No. 14/533,924, filed Nov. 5, 2014 (now U.S. Pat. No. 10,010,486), each of which is hereby incorporated by reference herein in its entirety. 
    
    
     TECHNICAL FIELD 
     This disclosure relates to adjustable indicators for container assemblies and, more particularly, to adjustable indicators for closures of medicine bottle containers that keep track of medication schedules, as well as methods for using and making the same. 
     BACKGROUND OF THE DISCLOSURE 
     Various containers are used to hold medicine or other contents that must be used in a sensitive fashion (e.g., according to a strict medication schedule). Some containers are provided with indicators that may inform a user about the manner in which the contents ought to be used. However, safely and securely managing the variable information of such indicators has heretofore been infeasible. 
     SUMMARY OF THE DISCLOSURE 
     This document describes adjustable indicators for containers and methods for using and making the same. 
     As an example, a cap for a bottle may include a closure operative to be coupled to the bottle for closing the bottle. The closure may include a closure body defining a closure space and a closure passageway provided through the closure body. The cap may also include a base including a base body coupled to the closure body within the closure space, where the base body and the closure body define an indicia space within the closure space. The cap may also include a dial including a dial body positioned within the indicia space. The cap may also include a gear assembly positioned within the indicia space between a portion of the base body and a portion of the dial body. The gear assembly may include a dial gear subassembly including a dial gear coupled to the dial body, and a user gear subassembly including a user gear and a user shaft extending away from the user gear. Rotation of the user shaft is operative to rotate the user gear, rotation of the user gear is operative to rotate the dial gear, rotation of the dial gear is operative to rotate the dial body, and rotation of the dial body is operative to change the portion of the dial body that is aligned with the closure passageway. 
     As another example, a cap for a bottle may include a closure operative to be coupled to the bottle for closing the bottle, a base coupled to the closure, a dial positioned between a portion of the base and a portion of the closure, and a gear assembly positioned between a portion of the base and a portion of the dial. The gear assembly may include a dial gear subassembly coupled to the dial, and a user gear subassembly. The gear assembly is operative to translate movement of the user gear subassembly into movement of the dial gear subassembly for moving the dial with respect to the closure. 
     As yet another example, a method for changing the portion of indicia on a dial within a bottle cap that is visible to a user through a passageway in the bottle cap may include pushing a user gear along a first axis towards a dial gear that is coupled to the dial. During the pushing, the method may also include rotating the user gear about the first axis. The method may also include rotating the dial gear and the dial about a second axis using the rotation of the user gear. 
     As yet another example, a cap for a bottle may include a closure operative to be coupled to the bottle for closing the bottle. The closure may include a closure body defining a closure space and a closure passageway provided through the closure body. The cap may also include a dial including a dial body positioned at least partially within the closure space, a biasing mechanism positioned at least partially within the closure space, an external force interface, a groove portion including a groove, and an interaction feature including an extender that is at least partially positioned within the groove. Application of external force on the external force interface is operative to move the extender in a compression direction within the groove. Movement of the extender in the compression direction within the groove is operative to compress the biasing mechanism. At least partial termination of external force on the external force interface is operative to decompress the biasing mechanism. Decompression of the biasing mechanism is operative to move the extender in an expansion direction within the groove. Movement of the extender in the expansion direction within the groove is operative to rotate the dial body. Rotation of the dial body is operative to change the portion of the dial body that is aligned with the closure passageway. 
     As yet another example, a cap for a bottle may include a closure operative to be coupled to the bottle for closing the bottle. The closure may include a closure body defining a closure space and a closure passageway provided through the closure body. The cap may also include a dial including a dial body positioned at least partially within the closure space and operative to rotate within the closure space about a particular axis, an external force interface, a path portion defining a path, and an interaction feature including an extender that is operative to move along the path. Application of external force on the external force interface by one of a user and the bottle is operative to move the extender in a first direction along a first segment of the path from a first portion of the first segment to a second portion of the first segment. At least partial termination of the external force on the external force interface is operative to move the extender in a second direction along a second segment of the path from a first portion of the second segment to a second portion of the second segment. Movement of the extender along the second segment of the path in the second direction is operative to rotate the dial body about the particular axis. Rotation of the dial body about the particular axis is operative to change the portion of the dial body that is aligned with the closure passageway. The first segment of the path extends parallel to the particular axis. The second segment of the path extends about at least a portion of the particular axis. 
     As yet another example, a method for changing the portion of indicia on a dial within a closure of a bottle cap that is visible to a user through a passageway in the closure may be provided, wherein the bottle cap includes the closure, the dial, a path component that defines a path, an interaction feature, and an external force interface coupled to the interaction feature. The method may include moving the interaction feature along a first segment of the path that extends in a first direction that is parallel to a particular axis when an external force is applied to the external force interface, and moving the interaction feature along a second segment of the path that extends from the first segment about at least a portion of the axis when the external force is at least partially terminated on the external force interface.

     DETAILED DESCRIPTION OF THE DISCLOSURE 
     This disclosure relates to adjustable indicators for container assemblies and, more particularly, to adjustable indicators for closures of medicine bottle containers that keep track of medication schedules, as well as methods for using and making the same. In some embodiments, a gear assembly may be provided with a cap of a container assembly. The gear assembly may be operative to translate motion (e.g., rotation) of a user handle into motion (e.g., rotation) of a dial for changing the portion of indicia of the dial that may be aligned with a passageway through the cap. The dial, indicia, and at least a portion of the gear assembly may be positioned within a secure indicia space defined by components of the cap, while the user handle may be positioned at least partially outside of that secure space, such that the secure space may prevent inadvertent or undesired movement of the dial unless dictated by the user handle. In some embodiments, two distinct motions may be applied to the user handle before the gear assembly may translate motion of the user handle into motion of the dial. For example, the user handle may be configured to push a user gear of the gear assembly towards a dial gear of the gear assembly, such that teeth of the user gear may mesh with teeth of the dial gear. Then, once the teeth are meshed, the user handle may be configured to rotate the user gear about a first axis, which may rotate the dial gear about a second axis for moving the dial, which may be coupled to the dial gear. The first axis may be the same as or different than the second axis. The gear assembly may provide a stopper mechanism that may prevent opposite rotation of either the user gear or the dial gear, such that the dial may only be moved in one direction with respect to the cap. In other embodiments, a path may be defined within a closure space of a closure of a cap assembly and an interaction feature may be forced to move along the path when an external force is applied to and then at least partially terminated from being applied to an external force interface of the cap assembly, which may rotate a dial about an axis within the closure space. The path may be provided by a surface of the closure and the interaction feature and external force interface may be provided by portions of the dial. Alternatively, the path may be provided by a surface of the dial and the interaction feature and external force interface may be provided by portions of the closure. Alternatively, the path may be provided by a surface of the dial and the interaction feature and external force interface may be provided by portions of a button. Alternatively, the path may be provided by a surface of a button and the interaction feature and external force interface may be provided by portions of the dial. The external force may be applied to the external force interface and then at least partially terminated manually by a user of the container assembly and/or automatically by a container when the container is coupled to and then at least partially decoupled from the cap assembly. A biasing mechanism may be provided for applying a force opposing such an external force for ensuring at least a portion of the travel of the interaction feature along the path when the external force is at least partially terminated. A first portion of the travel of the interaction feature along the path may be substantially linear vertical movement along a vertical segment of the path when an external force is applied in a linear direction to the external force interface. A second portion of the travel of the interaction feature along the path may be along a diagonal segment of the path about at least a portion of an axis for causing the dial to rotate about that axis when such an external force is at least partially terminated (e.g., overcome by the magnitude of the force exerted by the biasing mechanism). 
     FIGS.  1 - 6  (Assembly  100 ) 
       FIGS. 1-6  show an illustrative bottle container assembly  100  with an adjustable indicator that may be used for any suitable purpose, such as for keeping track of a schedule with respect to any suitable content  197  (e.g., medicine) that may be held by assembly  100 . As shown, assembly  100  may include a bottle  190  and a cap or cap subassembly  110  that may be coupled to bottle  190  for forming a closed container that may safely hold content  197  therein. For example, bottle  190  may include a bottle body that may include one or more side walls  195  that may extend from a closed bottom end  199  to an at least partially open top end  191  for defining an interior bottle space  193 . Bottle  190  may be configured such that a user may insert content  197  through open end  191  into bottle space  193  (e.g., along the −Z direction) and/or may remove content  197  from bottle space  193  through open end  191  (e.g., along the +Z direction). Bottle  190  may be any suitable container portion that may be configured to hold any suitable content  197  in any suitable way. Bottle  190  may be made of any suitable material or combination of materials and may be of any suitable dimensions. For example, although bottle  190  may be shown to define a cylindrically shaped bottle space  193  and a circular opening  191 , any suitable shapes of any suitable sizes may be provided by any suitable portions of bottle  190 . 
     Cap subassembly  110  may be configured to be removably coupled to bottle  190 , such that cap subassembly  110  may cover open end  191  for preventing a user from accessing bottle space  193  (e.g., content  197 ) when cap subassembly  110  is coupled to bottle  190 , and such that cap subassembly  110  may not cover at least a portion of open end  191  for enabling a user to access bottle space  193  (e.g., content  197 ) when cap subassembly  110  is not coupled to bottle  190 . Assembly  100  may be configured in any suitable way for enabling cap subassembly to be removably coupled to bottle  190 . As just one example, as shown in  FIGS. 1-6 , bottle  190  may include at least one cap attachment feature  192  (e.g., one or more male threads protruding from an exterior surface of body  195  adjacent end  191 ) and cap subassembly  110  may include at least one bottle attachment feature  128  (e.g., one or more female threads protruding from an interior surface of cap subassembly  110 ), where bottle attachment feature  128  may be screwed or otherwise rotated down around cap attachment feature  192  (e.g., downwardly in the −Z direction about the Z-axis in the direction of arrow R 1 ) for securing cap subassembly  110  to bottle  190  over open end  191  (see, e.g.,  FIGS. 2 and 6 ). In some such embodiments, as shown, bottle attachment feature  128  may be configured to rotate with respect to cap attachment feature  192  about a longitudinal axis A for enabling cap subassembly  110  and bottle  190  to be removably coupled to one another (e.g., in the direction of arrow R 1  for coupling and in the direction of arrow R 2  for removing). It is to be understood that while arrow R 1  may be shown as a clockwise type rotation direction about the Z-axis (e.g., axis A) and that while arrow R 2  may be shown as a counter-clockwise type rotation direction about the Z-axis (e.g., axis A), these associations may be flipped or may be any other suitable opposing rotation directions or any other suitable translation directions. In such threaded embodiments, cap attachment feature  192  and bottle attachment feature  128  may provide a safety child-resistant mechanism (e.g., where cap subassembly  110  may be pushed downwardly in order to enable twisting or rotating for removing cap subassembly  110  from bottle  190 ). Cap attachment feature  192  and bottle attachment feature  128  may be any suitable combination of reciprocal or otherwise related features that may be configured to interact with each other for removably coupling cap subassembly  110  to bottle  190  (e.g., snaps, notches, clips, location or transition fits, etc.). Bottle  190  may also include a lip  194 , which may protrude from an exterior surface of body  195  below cap attachment feature  192 , where lip  194  may be configured to suspend cap subassembly  110  by at least a certain distance above closed end  199 . Cap attachment feature  192  and/or lip  194  may ensure a specific relationship between cap subassembly  110  and bottle  190  when cap subassembly  110  is coupled to bottle  190 . 
     Cap subassembly  110  may include an adjustable indicator that may be utilized for any suitable purpose, such as for keeping track of a schedule with respect to any suitable content  197 . As shown in  FIGS. 1-6 , for example, cap subassembly  110  may include a closure  120 , a dial  130 , a gear assembly  140 , and a base  170 . Closure  120  of cap  110  may include a closure body that may include one or more side walls  125  that may extend from an at least partially closed top end  121  to an at least partially open bottom end  129  for defining an interior closure space  123 . Bottle attachment feature  128  may be provided along an interior surface of a side wall  125  adjacent or otherwise near end  129 , or at any other suitable position of closure  120  (e.g., bottle attachment feature  128  may be provided on an external surface of closure  120  or along bottom end  129 ). Closure  120  may be configured to be removably coupled to bottle  190  for at least partially preventing content  197  from being removed from bottle space  197  and/or for maintaining the freshness of content  197 . Closure  120  may also include one or more closure indicia passageways  126  through any suitable portions of closure  120  for selectively exposing to a user one or more other portions of cap subassembly  100  (e.g., portions of dial  130 , as described below). As shown, closure indicia passageways  126  may include at least one top closure indicia passageway  126   t  that may be provided through the wall of top end  121  of closure  120 , at least one side closure indicia passageway  126   s  that may be provided through one or more side walls  125  of closure  120 , and/or at least one bottom closure indicia passageway (e.g., passageway  176  as described below with respect to base  170 ). As described below, each closure indicia passageway  126  may be a hollow opening through a wall or other portion of closure  120  or may be such an opening that may be covered by or otherwise configured to include a transparent or translucent material or any other suitable object (e.g., a magnifying glass  126   tm ,  126   sm , etc.) that may enable communication of information therethrough to a user of assembly  100 . Such an object positioned within an indicia passageway may be configured to prevent a user or other entity external to assembly  100  from interacting with dial  130  through that indicia passageway (e.g., such that dial  130  may not be moved within indicia spacing  183  except via interaction with gear assembly  140 ). Closure  120  may be made of any suitable material or combination of materials and may be of any suitable dimensions. For example, although closure  120  may be shown to defile a cylindrically shaped closure space  123  and a circular opening  129 , any suitable shapes of any suitable sizes may be provided by any suitable portions of closure  120 . In some embodiments, closure  120  may be configured to define a majority of the external appearance of cap subassembly  110  (e.g., at least a majority of the external appearance of the top and sides of cap subassembly  110 ). 
     Dial  130  of cap  110  may include a dial body that may include one or more side walls  135  that may extend from an at least partially closed top end  131  to an at least partially closed bottom end  139 . Dial  130  may include any suitable dial indicia  136  on any suitable portions of dial  130  for selective display to a user of assembly  100  (as described below). Dial indicia  136  may be stamped on dial  130 , provided by a sticker adhered to dial  130 , painted on dial  130  (e.g., with glow in the dark paint), etched into dial  130 , and/or provided via any other suitable method. As shown, dial indicia  136  may include top dial indicia  136   t  that may be provided on an exterior surface of top end  131  of dial  130 , side dial indicia  136   s  that may be provided on an exterior surface of one or more side walls  135  of dial  130 , and/or bottom dial indicia  136   b  that may be provided on an exterior surface of bottom end  139  of dial  130 . Dial  130  may be configured to fit at least partially within closure space  123 , such that dial  130  may be moved within closure space  123  with respect to closure  120  for selectively aligning different dial indicia  136  of dial  130  with a closure indicia passageway  126  of closure  120 . Dial  130  may be made of any suitable material or combination of materials and may be of any suitable dimensions. For example, although dial  130  may be shown to define a cylindrically shaped object with a circular top wall  131  and a circular bottom wall  139 , any suitable shapes of any suitable sizes may be provided by any suitable portions of dial  130 . 
     Base  170  of cap  110  may include a base body that may include one or more side walls  175  that may extend from an at least partially closed top end  171  to an at least partially closed bottom end  179 . Base  170  may be configured to be coupled (e.g., permanently or removably) to closure  120 , such that, for example, base  170  and closure  120  may together define at least a portion of an indicia space  183  within which dial  130  may be positioned. For example, as shown in  FIGS. 1-6 , base  170  may include at least one closure attachment feature  174  (e.g., one or more notches protruding from an exterior surface of base  170 ) and closure  120  may include at least one base attachment feature  124  (e.g., one or more grooves or female threads protruding from an interior surface of closure  120 ), where closure attachment feature  174  may snap into or otherwise fit base  170  within base attachment feature  124  for securing base  170  within closure space  123 , which may thereby define a reduced indicia space  183  between closure  120  and base  170  (see, e.g.,  FIG. 6 ). In some such embodiments, as shown, base  170  may be pushed upwardly (e.g., in the ±Z direction) for interlocking with base attachment feature  124  of closure  120 . Base attachment feature  124  may be positioned above bottle attachment feature  128  within closure space  123  of closure  120  such that base  170  may be coupled to closure  120  while still enabling bottle attachment feature  128  to removably couple closure  120  to bottle  190 . While closure space  123  may be defined by the interior surface(s) of side wall(s)  125 , top end  121 , and bottom end  129  of closure  120 , indicia space  183  may be defined by the interior surface(s) of side wall(s)  125  and top end  121  of closure  120  as well as by base  170 , such that indicia space  183  may be a portion of closure space  123 . Thus, base  170  may be configured to fit at least partially within closure space  123 , such that base  170  may define at least a portion of the bottom of indicia space  183 . As shown and as described below, base  170  may also include a base indicia passageway  176  that may be provided through the base body from top end  171  to bottom end  179 , where such base indicia passageway  176  may also be referred to herein as a bottom closure indicia passageway, as base  170  may act as a bottom of indicia space  183  defined by closure  120  at its top and sides. As described below, like each closure indicia passageway  126 , base indicia passageway  176  may be a hollow opening through a wall or other portion of base  170  or may be such an opening that may be covered by or otherwise configured to include a transparent or translucent material or any other suitable object (e.g., a magnifying glass  176   m ) that may enable communication of information therethrough to a user of assembly  100 . Such an object positioned within base indicia passageway  176  may be configured to prevent a user or other entity external to indicia space  183  from interacting with dial  130  through base indicia passageway  176  (e.g., such that dial  130  may not be moved within indicia spacing  183  except via interaction with gear assembly  140 ). Base  170  may be made of any suitable material or combination of materials and may be of any suitable dimensions. For example, although base  170  may be shown to define a disc or cylindrically shaped object with a circular top wall  171  and a circular bottom wall  179 , any suitable shapes of any suitable sizes may be provided by any suitable portions of base  170 . Base  170  may be a single molded piece to provide the entire structure of base  170 , which may or may not include component  172  described below. Dial  130  may be positioned within indicia space  183  when base  170  is coupled to closure  120  (see, e.g.,  FIG. 6 ). 
     Gear assembly  140  of cap  110  may be at least partially positioned within indicia space  183  along with dial  130 , and gear assembly  140  may be configured to selectively move dial  130  within indicia space  183  with respect to closure  120  for selectively aligning different dial indicia  136  with a closure indicia passageway  126  of closure  120 . Gear assembly  140  may include one or more gears that may be configured to translate a user motion that may be applied to a first portion of gear assembly  140  into movement of dial  130  with indicia space  183  (e.g., rotation of dial  130  about an axis A along a Z-axis). As shown in  FIGS. 1-6 , for example, gear assembly  140  may include an upper or dial gear subassembly  150  and a lower or user gear subassembly  160 . Dial gear subassembly  150  may include an upper or dial cogwheel or gear  152  and, in some embodiments, an upper or dial gear shaft  158  that may extend away from gear  152  along an axis of rotation of gear  152  (e.g., axis A along a Z-axis). Gear shaft  158  and gear  152  may be a single molded piece or may be distinct elements coupled via any suitable coupling features (e.g., glue, threading, etc.). User gear subassembly  160  may include a lower or user cogwheel or gear  162  and, in some embodiments, a lower or user gear shaft  168  that may extend away from gear  162  along an axis of rotation of gear  162  (e.g., axis B along a Z-axis that may be parallel to axis A). Gear shaft  168  and gear  162  may be a single molded piece or may be distinct elements coupled via any suitable coupling features (e.g., glue, threading, etc.). User gear subassembly  160  may also include a user handle  166  that may be coupled to a portion of gear  162  (e.g., at an end of gear shaft  168 ), such that a user may apply a user force or motion to handle  166  for rotating gear  162 . Gear shaft  168  and handle  166  may be a single molded piece or may be distinct elements coupled via any suitable coupling features (e.g., glue, threading, hinge, etc.). Gear assembly  140  may be configured to translate movement (e.g., rotation) of gear  162  into movement (e.g., rotation) of gear  152 , which may be configured to move (e.g., rotate) dial  130  with respect to closure  120  within indicia space  183 . For example, as shown, gear  162  may include teeth or cogs or any other suitable mechanical feature that may mesh with teeth or cogs or any other suitable mechanical feature of gear  152  to transmit torque therebetween within gear assembly  140  (e.g., as a transmission or gearbox). 
     Base  170  may be configured to support at least a portion of gear assembly  140  and/or dial  130  within indicia space  183  when base  170  is coupled to closure  120 . For example, as shown, at least a portion of user gear subassembly  160  (e.g., a bottom portion of gear  162 ) may be configured to rest against base  170  (e.g., against an exterior surface of top wall  171  of base  170 ). A user gear shaft opening  177  may be provided through base  170  (e.g., between top wall  171  and bottom wall  179 ) for enabling at least a portion of user gear shaft  168  and/or user handle  166  to extend therethrough from indicia space  183  to at least a portion of closure space  123  and/or bottle space  193  or for at least enabling a portion of gear subassembly  160  to be accessible therethrough, such that a portion of gear assembly  140  may be accessible to a user when cap  110  is not coupled to bottle  190  (e.g., when a user unscrews cap  110  from bottle  190  for accessing contents  197 ). Such accessibility to a portion of gear subassembly  160  by a user external to indicia space  183  (e.g., via user gear shaft opening  177  of base  170 ) may enable a user of assembly  100  to apply a user force or motion to handle  166  for rotating gear  162 . Alternatively or additionally, in some embodiments, user gear shaft opening  177  of base  170  may at least partially define an axis of rotation of user gear  162  and/or may otherwise limit at least a portion of a path along which at least a portion of user gear subassembly  160  may travel (e.g., by preventing or limiting movement of gear subassembly  160  along the X-axis and/or along the Y-axis within indicia space  183 ). For example, as shown, user gear  162  may be configured to rotate about an axis B, and gear shaft  168  may extend away from gear  162  along axis B, such that gear shaft opening  177  may align with axis B. Additionally or alternatively, as shown, at least a portion of dial gear subassembly  150  (e.g., a top portion of gear  152 ) may be coupled to dial  130  (e.g., non-rotatably affixed (e.g., via an adhesive or a bolt) to an exterior surface of bottom wall  139  of dial  130 ), such that movement of gear subassembly  150  may provide movement of dial  130  (e.g., rotational movement about axis A). In some embodiments, a dial gear shaft opening  173  may be provided through at least a portion of base  170  (e.g., through top wall  171 ), where opening  173  may at least partially define an axis of rotation of dial gear  152  and/or may otherwise limit at least a portion of a path along which at least a portion of dial gear subassembly  150  may travel (e.g., by preventing or limiting movement of gear subassembly  150  along the X-axis and/or along the Y-axis within indicia space  183 ). For example, as shown, dial gear  152  may be configured to rotate about an axis A, and gear shaft  158  may extend away from gear  152  along axis A, such that gear shaft opening  173  may align with axis A. However, in some embodiments, gear shaft opening  173  and/or gear shaft  158  may not be necessary and other features of assembly  100  may define axis A about which gear  152  may rotate. For example, the positioning of base  170 , gear subassembly  160 , and dial  130  within indicia space  183  may limit the manner in which gear subassembly  150  may move within indicia space  183  (e.g., only to movement about axis A). In some embodiments, as shown in  FIGS. 1-6 , an interior surface of top end  121  of closure  120  may include a dial movement feature  127  and an exterior surface of top end  131  of dial  130  may include a closure movement feature  137 , where such features  127  and  137  may interact with one another to at least partially define an axis of rotation of dial  130  with respect to closure  120  (e.g., axis A) or otherwise aid or limit such movement (e.g., by preventing or limiting movement of dial  130  along the X-axis and/or along the Y-axis within indicia space  183 ), for example, where feature  137  may be a nub that may extend into a cut out or notch  127 . In some embodiments, the thickness of dial  130  along the Z-axis combined with the thickness of gear assembly  140  along the Z-axis may be substantially equal to or slightly less than the thickness of indicia space  183  along the Z-axis, such that dial  130  and/or gear assembly  140  may be prevented or limited with respect to movement along the Z-axis. 
     As just one example of use, a user may interact with handle  166  of user gear subassembly  160 , as may be accessible to a user through opening  177  of base  170 , for rotating gear shaft  168  and/or gear  162  in the direction of arrow R 2  about axis B, which may in turn rotate gear  152  of dial subassembly  150  in the direction of arrow R 1  about axis A, which may in turn rotate dial  130  in the direction of arrow R 1  about axis A. Such rotation of dial  130  in the direction of arrow R 1  about axis A within indicia space  183  with respect to closure  120  may alter the particular portion of dial  130  and, thus, the particular portion of dial indicia  136  that may be aligned with a particular closure indicia passageway  126 , which may alter what information may be provided to a user of assembly  100  by that particular portion of dial indicia  136 . For example, as shown in  FIGS. 1-6 , top dial indicia  136   t  may include seven distinct indications or marks respectively indicative of one of the seven days of the calendar week, while side dial indicia  136   s  may include seven distinct indications or marks, each of which may be adjacent a respective one of the indications of top dial indicia  136   t  and may be indicative of a particular time of day, and while bottom dial indicia  136   b  may include seven distinct indications or marks, each of which may be adjacent a respective one of the indications of side dial indicia  136   s  and may be indicative of a particular dosage (e.g., number of pills of content  197 ). In such embodiments, a particular set of adjacent indications including one from each of dial indicia  136   t ,  136   s , and  136   b  may be aligned with a set of respective adjacent passageways of indicia space  183  including indicia passageways  126   t ,  126   s , and  176 , such that assembly  100  may be configured to expose a particular day of the week, a particular time of day, and a particular dosage to a user of assembly  100  via cap subassembly  110 . For example, as shown in  FIG. 2 , when dial  130  is at a first particular orientation with respect to closure  120  and base  170  within indicia space  183 , a first day of the week indication “Sat.” of top dial indicia  136   t  may be aligned with and visible through indicia passageway  126   t , and a first time of day indication “10:30 PM” of side dial indicia  136   s  may be aligned with and visible through indicia passageway  126   s , and a first dosage indication “1 Pill” of bottom dial indicia  136   b  may be aligned with and visible through indicia passageway  176  (see, e.g., the orientation of  FIG. 6 , which may only be visible to a user of assembly  100  when cap  110  is removed from bottle  190 ). However, when dial  130  is rotated in the direction of arrow R 1  about axis A within indicia space  183  with respect to closure  120  from such a first orientation to a second orientation, the particular portion of dial  130  and, thus, the particular portion of dial indicia  136  that may be aligned with such indicia passageways  126 / 176  may be altered, for example, such that a second day of the week indication “Sun.” of top dial indicia  136   t  may be aligned with and visible through indicia passageway  126   t , a second time of day indication “10:30 PM” of side dial indicia  136   s  may be aligned with and visible through indicia passageway  126   s , and a second dosage indication “1 Pill” of bottom dial indicia  136   b  may be aligned with and visible through indicia passageway  176 . This may enable a user of assembly  100  to update the information communicated to the user by dial  130  through cap subassembly  110  daily after the user takes the appropriate content  197  of bottle  190  for that day so that the user will be reminded on the appropriate dosage for the following day. It is to be understood that any other or any additional suitable information may be described by any one or more of the various dial indicia groupings  136   t ,  136   b , and  136   s . Moreover, it is to be understood that two or more passageways  126 / 176  of cap subassembly  110  may be positioned in any suitable arrangement about cap subassembly  110  and need not be provided at least partially within a single plane (e.g., the X-Z plane of  FIG. 6 ), which would thereby allow two or more dial indications  136  to be exposed that are not adjacent one another (e.g., not at least partially within a single plane). 
     While cap subassembly  110  may be configured to enable rotation of dial  130  in the direction of arrow R 1  about axis A within indicia space  183  with respect to closure  120  from a first orientation to a second orientation (e.g., to keep track of a medication schedule for content  197  of bottle  190 ) by enabling user rotation of handle  166  in the direction of arrow R 2  about axis B, cap subassembly  110  may be configured to prevent rotation of dial  130  in the opposite direction of arrow R 2  about axis A. For example, as shown, gear assembly  140  may include a ratchet component  142  with ratcheting teeth/notches or other suitable features and base  170  may include a stopper component  172  with a tensioned free end that may be configured to interact with ratchet component  142  for preventing rotation of gear subassembly  150  and, thus, dial  130  in the direction of arrow R 2  while enabling rotation of gear subassembly  150  in the direction of arrow R 1 . Ratchet component  142  may be provided anywhere along any portion of gear assembly  140  and base  170  may be configured to provide stopper component  172  at any suitable position with indicia space  183  that may enable proper interaction between components  142  and  172 . For example, as shown in  FIGS. 4 and 6 , ratchet component  142  may be provided along a portion of gear subassembly  150  (e.g., adjacent a top portion of gear  152  at or near dial  130 ) and base  170  may provide stopper component  172  just adjacent ratchet component  142  in the +X direction (e.g., at the top end of an extension body  178  that may extend from a top surface of the base body of base  170 ), such that a free end of stopper component  172  may enable rotation of ratchet component  142  and, thus, gear  152  and dial  130  in the direction of arrow R 1  about axis A and at the same time prevent rotation of ratchet component  142  and, thus, gear  152  and dial  130  in the direction of arrow R 2  about axis A (e.g., due to the geometrical relationship between teeth or other suitable features of ratchet component  142  and the free end of stopper component  172 ). This may prevent a user from rotating gear assembly  140  in the wrong direction (e.g., by an intentional user force but in an incorrect direction). Moreover, interaction of ratchet component  142  and stopper component  172  may emit a sound that may be audible to a user (e.g., a clicking sound) each time ratchet component  142  is rotated or advanced with respect to stopper component  172 , which may provide a user with an audible feedback to user adjustment of the indicia of assembly  100 . Additionally or alternatively, interaction of ratchet component  142  and stopper component  172  may generate a tactile resistance and then release that may be felt by a user each time ratchet component  142  is rotated or advanced with respect to stopper component  172 , which may provide a user with a tactile or haptic feedback to user adjustment of the indicia of assembly  100 . In some embodiments, stopper component  172  may be tensioned by a suitable amount such that the free end of stopper component  172  may exert a suitable force on ratchet component  142  for even preventing rotation of dial  130  in the direction of arrow R 1  about axis A, where such a force may be overcome by an intentional user force on handle  166  but that may not be overcome by any unintentional forces to which cap subassembly  110  may be susceptible during normal use of assembly  100 , such that components  142 / 172  may enable proper rotation of dial  130  in the direction of arrow R 1  but only if at least a certain amount of threshold force is applied to gear assembly  140  (e.g., to handle  166 ). 
     Additionally or alternatively to being provided with ratchet component and stopper component (e.g., ratchet component  142  and stopper component  172 ), gear assembly  140  may be configured to have a resting state in which movement of gear subassembly  150  may not translate into motion of gear subassembly  160  (and vice versa) and an active state in which movement of gear subassembly  150  may translate into motion of gear subassembly  160  (and vice versa). For example, as shown in  FIG. 6 , gear assembly  140  may be in a resting state, whereby a spacing distance  141  may exist between gear  152  and gear  162  (e.g., along the X-axis and/or along the Z-axis of  FIG. 6 ), such that any rotation of user gear  162  in such a resting state (e.g., about axis B in the direction of arrow R 1  or arrow R 2 ) would not be translated into a rotation of dial gear  152 . In order to reconfigure gear assembly  140  from such a resting state into an active state, a user may first apply an upward force (e.g., longitudinal force in the +Z direction along axis B) on gear subassembly  160  (e.g., via handle  166 , such as along a longitudinal axis of gear shaft  168 ), such that gear  162  may be moved upwards by spacing distance  141  in order to contact gear  152  (e.g., such that teeth of gear  162  may mesh with teeth of gear  152 ), and then the user may apply a rotation force (e.g., in the direction of arrow R 2  about axis B) to user gear subassembly  160  (e.g., via handle  166 ) for rotating meshed dial gear  152  in the direction of arrow R 1  about axis A. Therefore, like a safety or child-resistant mechanism may be provided by bottle attachment feature  128  and cap attachment feature  192  that may require cap subassembly  110  be pushed downwardly in order to enable twisting or rotating for removing cap subassembly  110  from bottle  190 , gear assembly  140  may provide a safety or child-resistant mechanism that may require user gear subassembly  160  be pushed towards dial gear subassembly  150  in order to enable effective rotation of user gear subassembly  160  for translating dial gear subassembly  150  (e.g., for updating exposed dial indicia  136 ). This may help prevent unintentional rotation of dial  130  and, thus, unintentional updating of exposed dial indicia  136 . Spacing distance  141  may be any suitable distance for any suitable assembly of any suitable use case, such as 0.125 inches (e.g., along the Z-axis) for a pill bottle container. 
     By preventing inadvertent or undesired movement of dial  130  within indicia space  183  through use of ratchet/stopper components  142 / 172  and/or use of spacing distance  141 , and/or by preventing user access to dial  130  and gear assembly  140  externally to assembly  100 , but instead by limiting user access to dial  130  via gear assembly  140  when cap  110  has been removed from bottle  190 , assembly  100  may provide a reliable and easy to use indicator mechanism (e.g., for tracking a medication schedule). By providing at least three distinct sets of dial indicia indicia  136   t ,  136   s , and  136   b ) via respective passageways to a user, various amounts of helpful information may be simultaneously communicated to a user for managing the content of assembly  100 . Although, it is to be understood, that only one or two of such indicia may be provided in other embodiments. In yet other embodiments, more than three of such indicia may be provided (e.g., two distinct sets of indicia may be provided along different heights of a side wall  135  of dial  130  (e.g., a second set of side dial indicia may be provided above or below side dial indicia  136   s  while a second distinct side closure indicia passageway may be provided above or below side closure indicia passageway  126   s ). It is to be understood that, in some embodiments, as shown, at least a portion of side wall  135  of dial  130  and/or at least a portion of side wall  125  of closure  120  may extend (e.g., in a Y-Z plane) parallel to the axis of rotation of dial  130  within closure  120  (e.g., axis A along an axis Z), while at least a portion of top  131  of dial  130  and/or at least a portion of top  121  of closure  120  may extend (e.g., in an X-Y plane) perpendicularly to the axis of rotation of dial  130  within closure  120  (e.g., axis A along an axis Z), and while at least a portion of bottom  139  of dial  130  and/or at least a portion of bottom  179  of base  170  may extend (e.g., in an X-Y plane) perpendicularly to the axis of rotation of dial  130  within closure  120  (e.g., axis A along an axis Z). 
     FIG.  7  (Assembly  200 ) 
       FIG. 7  shows another illustrative bottle container assembly  200 , which may be similar to assembly  100  of  FIGS. 1-6  but may include a hollow dial within which at least a portion of a gear assembly may reside. Assembly  200  of  FIG. 7  may include similar components to assembly  100  of  FIGS. 1-6 , with components of assembly  200  of  FIG. 7  being labeled with “2xx” reference labels that may correspond to the “1xx” reference labels of the labeled components of assembly  100  of  FIGS. 1-6 , where differences therebetween may be described below. As shown, assembly  200  may include a bottle  290  and a cap  210  that may be coupled to bottle  290  for forming a closed container that may safely hold content therein. For example, bottle  290  may include a bottle body that may include one or more side walls  295  that may extend from a closed bottom end (not shown) to an at least partially open top end  291  for defining an interior bottle space  293 . Bottle  290  may be configured such that a user may insert content (not shown) through open end  291  into bottle space  293  (e.g., along the −Z direction) and/or may remove content from bottle space  293  through open end  291  (e.g., along the ±Z direction). Bottle  290  may be any suitable container portion that may be configured to hold any suitable content in any suitable way. Bottle  290  may be made of any suitable material or combination of materials and may be of any suitable dimensions. 
     Cap  210  may be configured to be removably coupled to bottle  290 , such that cap  210  may cover open end  291  for preventing a user from accessing bottle space  293  when cap  210  is coupled to bottle  290 , and such that cap  210  may not cover at least a portion of open end  291  for enabling a user to access bottle space  293  when cap  210  is not coupled to bottle  290 . Assembly  200  may be configured in any suitable way for enabling cap subassembly to be removably coupled to bottle  290 . As just one example, bottle  290  may include at least one cap attachment feature  292  and cap  210  may include at least one bottle attachment feature  228 , where cap attachment feature  292  and bottle attachment feature  228  may be any suitable combination of reciprocal or otherwise related features that may be configured to interact with each other for removably coupling cap  210  to bottle  290  (e.g., threads, snaps, notches, clips, location or transition fits, etc.). Bottle  290  may also include a lip  294 , which may protrude from an exterior surface of body  295  below cap attachment feature  292 , where lip  294  may be configured to suspend cap subassembly  210  by at least a certain distance above the closed end. Cap attachment feature  292  and/or lip  294  may ensure a specific relationship between cap  210  and bottle  290  when cap  210  is coupled to bottle  290 . 
     Cap  210  may include a closure  220 , a dial  230 , a gear assembly  240 , and a base  270 . Closure  220  of cap  210  may include a closure body that may include one or more side walls  225  that may extend from an at least partially closed top end  221  to an at least partially open bottom end  229  for defining an interior closure space  223 . Closure  220  may also include one or more closure indicia passageways  226  through any suitable portions of closure  220  for selectively exposing to a user one or more other portions of cap subassembly  200  (e.g., portions of dial  230 , as described below). As shown, closure indicia passageways  226  may include at least one top closure indicia passageway  226   t  that may be provided through the wall of top end  221  of closure  220 , at least one side closure indicia passageway  226   s  that may be provided through one or more side walls  225  of closure  220 , and/or at least one bottom closure indicia passageway (e.g., passageway  276  as described below with respect to base  270 ). As described below, each closure indicia passageway  226  may be a hollow opening through a wall or other portion of closure  220  or may be such an opening that may be covered by or otherwise configured to include a transparent or translucent material or any other suitable object (e.g., a magnifying glass  226   tm ,  226   sm , etc.) that may enable communication of information therethrough to a user of assembly  200 . Closure  220  may be made of any suitable material or combination of materials and may be of any suitable dimensions. 
     Dial  230  of cap  210  may include a dial body that may include one or more side walls  235  that may extend from an at least partially closed top end  231  to an at least partially closed bottom end  239 . Unlike dial  130 , which may be a solid or closed shape, dial  230  may define an interior dial space  233 , which may be accessible via a dial opening  238 , which may be provided through any suitable portion of the dial body, such as through bottom end  239 . Dial  230  may include any suitable dial indicia  236  on any suitable portions of dial  230  for selective display to a user of assembly  200 . As shown, dial indicia  236  may include top dial indicia  236   t  that may be provided on an exterior surface of top end  231  of dial  230 , side dial indicia  236   s  that may be provided on an exterior surface of one or more side walls  235  of dial  230 , and/or bottom dial indicia  236   b  that may be provided on an exterior surface of bottom end  239  of dial  230  (e.g., adjacent opening  238  along the X-axis). Dial  230  may be configured to fit at least partially within closure space  223 , such that dial  230  may be moved within closure space  223  with respect to closure  220  for selectively aligning different dial indicia  236  of dial  230  with a closure indicia passageway  226  of closure  220 . Dial  230  may be made of any suitable material or combination of materials and may be of any suitable dimensions. 
     Base  270  of cap  210  may include a base body that may include one or more side walls  275  that may extend from an at least partially closed top end  271  to an at least partially closed bottom end  279 . Base  270  may be configured to be coupled (e.g., permanently or removably) to closure  220 , such that, for example, base  270  and closure  220  may together define at least a portion of an indicia space  283  within which dial  230  may be positioned. For example, base  270  may include at least one closure attachment feature (e.g., the shape of an exterior surface of side wall(s)  275  of base  270 ) and closure  220  may include at least one base attachment feature  224  (e.g., one or more grooves or female threads protruding from an interior surface of closure  220 ), where base  270  may snap into or otherwise fit base  270  within base attachment feature  224  for securing base  270  within closure space  223 , which may thereby define a reduced indicia space  283  between closure  220  and base  270 . Base attachment feature  224  may be positioned above bottle attachment feature  228  within closure space  223  of closure  220  such that base  270  may be coupled to closure  220  while still enabling bottle attachment feature  228  to removably couple closure  220  to bottle  290 . While closure space  223  may be defined by the interior surface(s) of side wall(s)  225 , top end  221 , and bottom end  229  of closure  220 , indicia space  283  may be defined by the interior surface(s) of side wall(s)  225  and top end  221  of closure  220  as well as by base  270 , such that indicia space  283  may be a portion of closure space  223 . Thus, base  270  may be configured to fit at least partially within closure space  223 , such that base  270  may define at least a portion of the bottom of indicia space  283 . As shown, base  270  may also include a base indicia passageway  276  that may be provided through the base body from top end  271  to bottom end  279 , where such base indicia passageway  276  may also be referred to herein as a bottom closure indicia passageway, as base  270  may act as a bottom of indicia space  283  defined by closure  220  at its top and sides. As described below, like each closure indicia passageway  226 , base indicia passageway  276  may be a hollow opening through a wall or other portion of base  270  or may be such an opening that may be covered by or otherwise configured to include a transparent or translucent material or any other suitable object (e.g., a magnifying glass  276   m ) that may enable communication of information therethrough to a user of assembly  200 . Base  270  may be made of any suitable material or combination of materials and may be of any suitable dimensions. Dial  230  may be at least partially positioned within indicia space  283  when base  270  is coupled to closure  220 . Moreover, as shown, unlike assembly  100 , at least a portion of base  270  may be positioned within dial space  233 . While a bottom portion (e.g., bottom  279 ) of base  270  may be substantially flat (e.g., like bottom  179  of base  170 ), at least a portion of a profile of a top portion (e.g., top  271 ) of base  270  may vary in height, for example, such that one portion of base  270  may pass up into dial space  233  via dial opening  238  (e.g., for supporting at least a portion of gear assembly  240 ) while another portion of base  270  may span bottom  239  of dial  230  (e.g., for defining a bottom of indicia space  283 ). 
     Gear assembly  240  of cap  210  may be at least partially positioned within indicia space  283  along with dial  230 , and gear assembly  240  may be configured to selectively move dial  230  within indicia space  283  with respect to closure  220  for selectively aligning different dial indicia  236  with a closure indicia passageway  226 / 276  of closure  220 /base  270 . Moreover, as shown, unlike assembly  100 , at least a portion of gear assembly  240  may be positioned within dial space  233 . Gear assembly  240  may include one or more gears that may be configured to translate a user motion that may be applied to a first portion of gear assembly  240  into movement of dial  230  with indicia space  283  (e.g., rotation of dial  230  about an axis A along a Z-axis). As shown, gear assembly  240  may include an upper or dial gear subassembly  250  and a lower or user gear subassembly  260 . Dial gear subassembly  250  may include an upper or dial cogwheel or gear  252  and, in some embodiments, an upper or dial gear shaft  258  that may extend away from gear  252  along an axis of rotation of gear  252  (e.g., axis A along a Z-axis). User gear subassembly  260  may include a lower or user cogwheel or gear  262  and, in some embodiments, a lower or user gear shaft  268  that may extend away from gear  262  along an axis of rotation of gear  262  (e.g., axis B along a Z-axis that may be parallel to axis A). User gear subassembly  260  may also include a user handle  266  that may be coupled to a portion of gear  262  (e.g., at an end of gear shaft  268 ), such that a user may apply a user force or motion to handle  266  for rotating gear  262 . Gear assembly  240  may be configured such that rotation of gear  262  may be configured to rotate or otherwise translate gear  252 , which may be configured to rotate or otherwise translate dial  230  with respect to closure  220  within indicia space  283 . For example, as shown, gear  262  may include teeth or cogs or any other suitable mechanical feature that may mesh with teeth or cogs or any other suitable mechanical feature of gear  252  to transmit torque therebetween within gear assembly  240  (e.g., as a transmission or gearbox). 
     Base  270  may be configured to support at least a portion of gear assembly  240  and/or dial  230  within indicia space  283  when base  270  is coupled to closure  220 . For example, as shown, at least a portion of user gear subassembly  260  (e.g., a bottom portion of gear  262 ) may be configured to rest against base  270  (e.g., against an exterior surface of top wall  271  of base  270 ). A user gear shaft opening  277  may be provided through base  270  (e.g., between top wall  271  and bottom wall  279 ) for enabling at least a portion of user gear shaft  268  and/or user handle  266  to extend therethrough from indicia space  283  to at least a portion of closure space  223  and/or bottle space  293  or for at least enabling a portion of gear subassembly  260  to be accessible therethrough, such that a portion of gear assembly  240  may be accessible to a user when cap  210  is not coupled to bottle  290  (e.g., when a user unscrews cap  210  from bottle  290  for accessing contents  297 ). Such accessibility to a portion of gear subassembly  260  by a user external to indicia space  283  (e.g., via user gear shaft opening  277  of base  270 ) may enable a user of assembly  200  to apply a user force or motion to handle  266  for rotating gear  262 . Alternatively or additionally, in some embodiments, user gear shaft opening  277  of base  270  may at least partially define an axis of rotation of user gear  262  and/or may otherwise limit at least a portion of a path along which at least a portion of user gear subassembly  260  may travel (e.g., by preventing or limiting movement of gear subassembly  260  along the X-axis and/or along the Y-axis within indicia space  283 ). For example, as shown, user gear  262  may be configured to rotate about an axis B, and gear shaft  268  may extend away from gear  262  along axis B, such that gear shaft opening  277  may align with axis B. Additionally or alternatively, as shown, at least a portion of dial gear subassembly  250  (e.g., a top portion of gear  252 ) may be coupled to dial  230  (e.g., to an interior surface of top wall  231  of dial  230  within dial space  233 ), such that movement of gear subassembly  250  may provide movement of dial  230  (e.g., rotational movement about axis A). In some embodiments, a dial gear shaft opening  273  may be provided through at least a portion of base  270  (e.g., through top wall  271 ), where opening  273  may at least partially define an axis of rotation of dial gear  252  and/or may otherwise limit at least a portion of a path along which at least a portion of dial gear subassembly  250  may travel (e.g., by preventing or limiting movement of gear subassembly  250  along the X-axis and/or along the Y-axis within indicia space  283 ). For example, as shown, dial gear  252  may be configured to rotate about an axis A, and gear shaft  258  may extend away from gear  252  along axis A, such that gear shaft opening  273  may align with axis A. However, in some embodiments, gear shaft opening  273  and/or gear shaft  258  may not be necessary and other features of assembly  200  may define axis A about which gear  252  may rotate. For example, the positioning of base  270 , gear subassembly  260 , and dial  230  within indicia space  283  may limit the manner in which gear subassembly  250  may move within indicia space  283  (e.g., only to movement about axis A). In some embodiments, as shown in  FIG. 7 , an interior surface of top end  221  of closure  220  may include a dial movement feature  227  and an exterior surface of top end  231  of dial  230  may include a closure movement feature  237 , where such features  227  and  237  may interact with one another to at least partially define an axis of rotation of dial  230  with respect to closure  220  (e.g., axis A) or otherwise aid or limit such movement (e.g., by preventing or limiting movement of dial  230  along the X-axis and/or along the Y-axis within indicia space  283 ), for example, where feature  237  may be a nub that may extend into a cut out or notch  227 . In some embodiments, the thickness of the wall of top end  231  of dial  230  along the Z-axis combined with the thickness of gear assembly  240  along the Z-axis may be substantially equal to or slightly less than a thickness of indicia space  283  along the Z-axis, such that dial  230  and/or gear assembly  240  may be prevented or limited with respect to movement along the Z-axis. 
     As just one example of use, a user may interact with handle  266  of user gear subassembly  260 , as may be accessible to a user through opening  277  of base  270 , for rotating gear shaft  268  and/or gear  262  in the direction of arrow R 2  about axis B, which may in turn rotate gear  252  of dial subassembly  250  in the direction of arrow R 1  about axis A, which may in turn rotate dial  230  in the direction of arrow R 1  about axis A. Such rotation of dial  230  in the direction of arrow R 1  about axis A within indicia space  283  with respect to closure  220  may alter the particular portion of dial  230  and, thus, the particular portion of dial indicia  236  that may be aligned with a particular closure indicia passageway  226 / 276 , which may alter what information may be provided to a user of assembly  200  by that particular portion of dial indicia  236 . For example, as shown in  FIG. 7 , when dial  230  is at a first particular orientation with respect to closure  220  and base  270  within indicia space  283 , a first indication of top dial indicia  236   t  may be aligned with and visible through indicia passageway  226   t , a first indication of side dial indicia  236   s  may be aligned with and visible through indicia passageway  226   s , and a first indication of bottom dial indicia  236   b  may be aligned with and visible through indicia passageway  276  (e.g., visible by a user when cap  210  is removed from bottle  290 ). However, when dial  230  is rotated in the direction of arrow R 1  about axis A within indicia space  283  with respect to closure  220  from such a first orientation to a second orientation, the particular portion of dial  230  and, thus, the particular portion of dial indicia  236  that may be aligned with such indicia passageways  226 / 276  may be altered. A liquid proof cover  269  may be provided over at least a portion of gear assembly  240 . For example, as shown in  FIG. 7 , any suitable cover  269  may be provided over a portion of the exterior surface of bottom  279  of base  270  (e.g., over opening  277  and any portion of gear assembly  240  that may extend out from opening  277  beyond bottom  279 ), whereby cover  269  may prevent any liquid or other element that may have a detrimental effect on the functionality of gear assembly  240  from entering into indicia space  283  via opening  277  (e.g., liquid contents of bottle  290 ). Cover  269  may be any suitable material (e.g., rubber) that may be flexible enough to enable a user to grasp/push/rotate handle  266  or otherwise interact with gear assembly  240  for moving dial  230 . 
     While cap subassembly  210  may be configured to enable rotation of dial  230  in the direction of arrow R 1  about axis A within indicia space  283  with respect to closure  220  from a first orientation to a second orientation (e.g., to keep track of a medication schedule for content of bottle  290 ) by enabling user rotation of handle  266  in the direction of arrow R 2  about axis B, cap subassembly  210  may be configured to prevent rotation of dial  230  in the opposite direction of arrow R 2  about axis A. For example, as shown, gear assembly  240  may include a ratchet component  242  and base  270  may include a stopper component  272  that may be configured to interact with ratchet component  242  for preventing rotation of gear subassembly  250  and, thus, dial  230  in the direction of arrow R 2  while enabling rotation of gear subassembly  250  in the direction of arrow R 1 . For example, as shown, ratchet component  242  may be provided along a portion of gear subassembly  250  (e.g., adjacent a top portion of gear  252  at or near dial  230 ) and base  270  may provide stopper component  272  just adjacent ratchet component  242  in the +X direction (e.g., at the top end of an extension body  278  that may extend from a top surface  271  of the base body of base  270 ), such that a free end of stopper component  272  may enable rotation of ratchet component  242  and, thus, gear  252  and dial  230  in the direction of arrow R 1  about axis A and at the same time prevent rotation of ratchet component  242  and, thus, gear  252  and dial  230  in the direction of arrow R 2  about axis A (e.g., due to the geometrical relationship between teeth or other suitable features of ratchet component  242  and the free end of stopper component  272 ). Moreover, interaction of ratchet component  242  and stopper component  272  may provide a user with an audible and/or tactile feedback to user adjustment of the indicia of assembly  200 . In some embodiments, stopper component  272  may be tensioned by a suitable amount such that the free end of stopper component  272  may exert a suitable force on ratchet component  242  for even preventing rotation of dial  230  in the direction of arrow R 1  about axis A, where such a force may be overcome by an intentional user force on handle  266  but that may not be overcome by any unintentional forces to which cap subassembly  210  may be susceptible during normal use of assembly  200 , such that components  242 / 272  may enable proper rotation of dial  230  in the direction of arrow R 1  but only if at least a certain amount of threshold force is applied to gear assembly  240  (e.g., to handle  266 ). 
     Additionally or alternatively to being provided with ratchet component and stopper component (e.g., ratchet component  242  and stopper component  272 ), gear assembly  240  may be configured to have a resting state in which movement of gear subassembly  250  may not translate into motion of gear subassembly  260  (and vice versa) and an active state in which movement of gear subassembly  250  may translate into motion of gear subassembly  260  (and vice versa). For example, as shown in  FIG. 7 , gear assembly  240  may be in a resting state, whereby a spacing distance (e.g., similar to spacing distance  141 ) may exist between gear  252  and gear  262  (e.g., along the X-axis and/or along the Z-axis of  FIG. 7 ), such that any rotation of user gear  262  in such a resting state (e.g., about axis B in the direction of arrow R 1  or arrow R 2 ) would not be translated into a rotation of dial gear  252 . In order to reconfigure gear assembly  240  from such a resting state into an active state, a user may first apply an upward force (e.g., in the +Z direction along axis B) on gear subassembly  260  (e.g., via handle  266 ), such that gear  262  may be moved upwards by the spacing distance in order to contact gear  252  (e.g., such that teeth of gear  262  may mesh with teeth of gear  252 ), and then the user may apply a rotation force (e.g., in the direction of arrow R 2  about axis B) to user gear subassembly  260  (e.g., via handle  266 ) for rotating meshed dial gear  252  in the direction of arrow R 1  about axis A. This may help prevent unintentional rotation of dial  230  and, thus, unintentional updating of exposed dial indicia  236 . 
     By positioning at least a portion of base  270  and/or gear assembly  240  within a dial space  233  within dial  230  (e.g., by positioning at least a portion of base  270  and/or at least a portion of gear assembly  240  above bottom  239  of dial  230 ), a height of indicia space  283  between top  221  and bottom  279  of assembly  200  may be shorter than a height of indicia space  183  between top  121  and bottom  179  of assembly  100  for a given height of a dial (e.g., along the Z-axis), which may reduce the overall height of the cap subassembly. Additionally or alternatively, by positioning at least a portion of base  270  and/or gear assembly  240  within a dial space  233  within dial  230  (e.g., by positioning at least a portion of base  270  and/or at least a portion of gear assembly  240  above bottom  239  of dial  230 ), a distance between bottom dial indicia  236   b  on bottom dial wall  239  and base indicia passageway  276  through base  270  of assembly  200  may be shorter than a distance between bottom dial indicia  136   b  on bottom dial wall  139  and base indicia passageway  176  through base  170  of assembly  100  (e.g., along the Z-axis), which may increase a user&#39;s ability to view the bottom dial indicia. 
     FIG.  8  (Assembly  300 ) 
       FIG. 8  shows another illustrative bottle container assembly  300 , which may be similar to assembly  100  of  FIGS. 1-6  but may include a hollow dial within which at least a portion of a gear assembly may reside. Assembly  300  of  FIG. 8  may include similar components to assembly  100  of  FIGS. 1-6 , with components of assembly  300  of  FIG. 8  being labeled with “3xx” reference labels that may correspond to the “1xx” reference labels of the labeled components of assembly  100  of  FIGS. 1-6 , where differences therebetween may be described below. As shown, assembly  300  may include a bottle  390  and a cap  310  that may be coupled to bottle  390  for forming a closed container that may safely hold content therein. For example, bottle  390  may include a bottle body that may include one or more side walls  395  that may extend from a closed bottom end (not shown) to an at least partially open top end  391  for defining an interior bottle space  393 . Bottle  390  may be configured such that a user may insert content (not shown) through open end  391  into bottle space  393  (e.g., along the −Z direction) and/or may remove content from bottle space  393  through open end  391  (e.g., along the ±Z direction). Bottle  390  may be any suitable container portion that may be configured to hold any suitable content in any suitable way. Bottle  390  may be made of any suitable material or combination of materials and may be of any suitable dimensions. 
     Cap  310  may be configured to be removably coupled to bottle  390 , such that cap  310  may cover open end  391  for preventing a user from accessing bottle space  393  when cap  310  is coupled to bottle  390 , and such that cap  310  may not cover at least a portion of open end  391  for enabling a user to access bottle space  393  when cap  310  is not coupled to bottle  390 . Assembly  300  may be configured in any suitable way for enabling cap subassembly to be removably coupled to bottle  390 . As just one example, bottle  390  may include at least one cap attachment feature  392  and cap  310  may include at least one bottle attachment feature  328 , where cap attachment feature  392  and bottle attachment feature  328  may be any suitable combination of reciprocal or otherwise related features that may be configured to interact with each other for removably coupling cap  310  to bottle  390  (e.g., threads, snaps, notches, clips, location or transition fits, etc.). Bottle  390  may also include a lip  394 , which may protrude from an exterior surface of body  395  below cap attachment feature  392 , where lip  394  may be configured to suspend cap subassembly  310  by at least a certain distance above the closed end. Cap attachment feature  392  and/or lip  394  may ensure a specific relationship between cap  310  and bottle  390  when cap  310  is coupled to bottle  390 . 
     Cap  310  may include a closure  320 , a dial  330 , a gear assembly  340 , and a base  370 . Closure  320  of cap  310  may include a closure body that may include one or more side walls  325  that may extend from an at least partially closed top end  321  to an at least partially open bottom end  329  for defining an interior closure space  323 . Closure  320  may also include one or more closure indicia passageways  326  through any suitable portions of closure  320  for selectively exposing to a user one or more other portions of cap subassembly  300  (e.g., portions of dial  330 , as described below). As shown, closure indicia passageways  326  may include at least one top closure indicia passageway  326   t  that may be provided through the wall of top end  321  of closure  320  and/or at least one side closure indicia passageway  326   s  that may be provided through one or more side walls  325  of closure  320 . As described below, each closure indicia passageway  326  may be a hollow opening through a wall or other portion of closure  320  or may be such an opening that may be covered by or otherwise configured to include a transparent or translucent material or any other suitable object (e.g., a magnifying glass  326   tm ,  326   sm , etc.) that may enable communication of information therethrough to a user of assembly  300 . Closure  320  may be made of any suitable material or combination of materials and may be of any suitable dimensions. 
     Dial  330  of cap  310  may include a dial body that may include one or more side walls  335  that may extend from an at least partially closed top end  331  to an open bottom end  339 . Unlike dial  130 , which may be a solid or closed shape, dial  330  may define an interior dial space  333 , which may be accessible via open bottom end  339 . Dial  330  may include any suitable dial indicia  336  on any suitable portions of dial  330  for selective display to a user of assembly  300 . As shown, dial indicia  336  may include top dial indicia  336   t  that may be provided on an exterior surface of top end  331  of dial  330 , and/or side dial indicia  336   s  that may be provided on an exterior surface of one or more side walls  335  of dial  330 . Dial  330  may be configured to fit at least partially within closure space  323 , such that dial  330  may be moved within closure space  323  with respect to closure  320  for selectively aligning different dial indicia  336  of dial  330  with a closure indicia passageway  326  of closure  320 . Dial  330  may be made of any suitable material or combination of materials and may be of any suitable dimensions. 
     Base  370  of cap  310  may include a base body that may include one or more side walls  375  that may extend from an at least partially closed top end  371  to an at least partially closed bottom end  379 . Base  370  may be configured to be coupled (e.g., permanently or removably) to closure  320 , such that, for example, base  370  and closure  320  may together define at least a portion of an indicia space  383  within which dial  330  may be positioned. For example, base  370  may include at least one closure attachment feature (e.g., the shape of an exterior surface of side wall(s)  375  of base  370 ) and closure  320  may include at least one base attachment feature  324  (e.g., one or more grooves or female threads protruding from an interior surface of closure  320 ), where base  370  may snap into or otherwise fit base  370  within base attachment feature  324  for securing base  370  within closure space  323 , which may thereby define a reduced indicia space  383  between closure  320  and base  370 . Base attachment feature  324  may be positioned above bottle attachment feature  328  within closure space  323  of closure  320  such that base  370  may be coupled to closure  320  while still enabling bottle attachment feature  328  to removably couple closure  320  to bottle  390 . While closure space  323  may be defined by the interior surface(s) of side wall(s)  325 , top end  321 , and bottom end  329  of closure  320 , indicia space  383  may be defined by the interior surface(s) of side wall(s)  325  and top end  321  of closure  320  as well as by base  370 , such that indicia space  383  may be a portion of closure space  323 . Thus, base  370  may be configured to fit at least partially within closure space  323 , such that base  370  may define at least a portion of the bottom of indicia space  383 . Base  370  may be made of any suitable material or combination of materials and may be of any suitable dimensions. Dial  330  may be at least partially positioned within indicia space  383  when base  370  is coupled to closure  320 . Moreover, as shown, unlike assembly  100 , at least a portion of base  370  may be positioned within dial space  333 . 
     Gear assembly  340  of cap  310  may be at least partially positioned within indicia space  383  along with dial  330 , and gear assembly  340  may be configured to selectively move dial  330  within indicia space  383  with respect to closure  320  for selectively aligning different dial indicia  336  with a closure indicia passageway  326  of closure  320 . Moreover, as shown, unlike assembly  100 , at least a portion of gear assembly  340  may be positioned within dial space  333 . Gear assembly  340  may include one or more gears that may be configured to translate a user motion that may be applied to a first portion of gear assembly  340  into movement of dial  330  with indicia space  383  (e.g., rotation of dial  330  about an axis A along a Z-axis). As shown, gear assembly  340  may include an upper or dial gear subassembly  350  and a lower or user gear subassembly  360 . Dial gear subassembly  350  may include an upper or dial cogwheel or gear  352  and, in some embodiments, an upper or dial gear shaft  358  that may extend away from gear  352  along an axis of rotation of gear  352  (e.g., axis A along a Z-axis). User gear subassembly  360  may include a lower or user cogwheel or gear  362  and, in some embodiments, a lower or user gear shaft  368  that may extend away from gear  362  along an axis of rotation of gear  362  (e.g., axis B along a Z-axis that may be parallel to axis A). User gear subassembly  360  may also include a user handle  366  that may be coupled to a portion of gear  362  (e.g., at an end of gear shaft  368 ), such that a user may apply a user force or motion to handle  366  for rotating gear  362 . Gear assembly  340  may be configured such that rotation of gear  362  may be configured to rotate or otherwise translate gear  352 , which may be configured to rotate or otherwise translate dial  330  with respect to closure  320  within indicia space  383 . For example, as shown, gear  362  may include teeth or cogs or any other suitable mechanical feature that may mesh with teeth or cogs or any other suitable mechanical feature of gear  352  to transmit torque therebetween within gear assembly  340  (e.g., as a transmission or gearbox). 
     Base  370  may be configured to support at least a portion of gear assembly  340  and/or dial  330  within indicia space  383  when base  370  is coupled to closure  320 . For example, as shown, at least a portion of user gear subassembly  360  (e.g., a bottom portion of gear  362 ) may be configured to rest against base  370  (e.g., against an exterior surface of top wall  371  of base  370 ). A user gear shaft opening  377  may be provided through base  370  (e.g., between top wall  371  and bottom wall  379 ) for enabling at least a portion of user gear shaft  368  and/or user handle  366  to extend therethrough from indicia space  383  to at least a portion of closure space  323  and/or bottle space  393  or for at least enabling a portion of gear subassembly  360  to be accessible therethrough, such that a portion of gear assembly  340  may be accessible to a user when cap  310  is not coupled to bottle  390  (e.g., when a user unscrews cap  310  from bottle  390  for accessing contents  397 ). Such accessibility to a portion of gear subassembly  360  by a user external to indicia space  383  (e.g., via user gear shaft opening  377  of base  370 ) may enable a user of assembly  300  to apply a user force or motion to handle  366  for rotating gear  362 . Alternatively or additionally, in some embodiments, user gear shaft opening  377  of base  370  may at least partially define an axis of rotation of user gear  362  and/or may otherwise limit at least a portion of a path along which at least a portion of user gear subassembly  360  may travel (e.g., by preventing or limiting movement of gear subassembly  360  along the X-axis and/or along the Y-axis within indicia space  383 ). For example, as shown, user gear  362  may be configured to rotate about an axis B, and gear shaft  368  may extend away from gear  362  along axis B, such that gear shaft opening  377  may align with axis B. Additionally or alternatively, as shown, at least a portion of dial gear subassembly  350  (e.g., a top portion of gear  352 ) may be coupled to dial  330  (e.g., to an interior surface of top wall  331  of dial  330  within dial space  333 ), such that movement of gear subassembly  350  may provide movement of dial  330  (e.g., rotational movement about axis A). In some embodiments, a dial gear shaft opening  373  may be provided through at least a portion of base  370  (e.g., through top wall  371 ), where opening  373  may at least partially define an axis of rotation of dial gear  352  and/or may otherwise limit at least a portion of a path along which at least a portion of dial gear subassembly  350  may travel (e.g., by preventing or limiting movement of gear subassembly  350  along the X-axis and/or along the Y-axis within indicia space  383 ). For example, as shown, dial gear  352  may be configured to rotate about an axis A, and gear shaft  358  may extend away from gear  352  along axis A, such that gear shaft opening  373  may align with axis A. However, in some embodiments, gear shaft opening  373  and/or gear shaft  358  may not be necessary and other features of assembly  300  may define axis A about which gear  352  may rotate. For example, the positioning of base  370 , gear subassembly  360 , and dial  330  within indicia space  383  may limit the manner in which gear subassembly  350  may move within indicia space  383  (e.g., only to movement about axis A). In some embodiments, as shown in  FIG. 8 , an interior surface of top end  321  of closure  320  may include a dial movement feature  327  and an exterior surface of top end  331  of dial  330  may include a closure movement feature  337 , where such features  327  and  337  may interact with one another to at least partially define an axis of rotation of dial  330  with respect to closure  320  (e.g., axis A) or otherwise aid or limit such movement (e.g., by preventing or limiting movement of dial  330  along the X-axis and/or along the Y-axis within indicia space  383 ), for example, where feature  337  may be a nub that may extend into a cut out or notch  327 . In some embodiments, the thickness of the wall of top end  331  of dial  330  along the Z-axis combined with the thickness of gear assembly  340  along the Z-axis may be substantially equal to or slightly less than a thickness of indicia space  383  along the Z-axis, such that dial  330  and/or gear assembly  340  may be prevented or limited with respect to movement along the Z-axis. 
     As just one example of use, a user may interact with handle  366  of user gear subassembly  360 , as may be accessible to a user through opening  377  of base  370 , for rotating gear shaft  368  and/or gear  362  in the direction of arrow R 2  about axis B, which may in turn rotate gear  352  of dial subassembly  350  in the direction of arrow R 1  about axis A, which may in turn rotate dial  330  in the direction of arrow R 1  about axis A. Such rotation of dial  330  in the direction of arrow R 1  about axis A within indicia space  383  with respect to closure  320  may alter the particular portion of dial  330  and, thus, the particular portion of dial indicia  336  that may be aligned with a particular closure indicia passageway  326 , which may alter what information may be provided to a user of assembly  300  by that particular portion of dial indicia  336 . For example, as shown in  FIG. 8 , when dial  330  is at a first particular orientation with respect to closure  320  and base  370  within indicia space  383 , a first indication of top dial indicia  336   t  may be aligned with and visible through indicia passageway  326   t  and/or a first indication of side dial indicia  336   s  may be aligned with and visible through indicia passageway  326   s . However, when dial  330  is rotated in the direction of arrow R 1  about axis A within indicia space  383  with respect to closure  320  from such a first orientation to a second orientation, the particular portion of dial  330  and, thus, the particular portion of dial indicia  336  that may be aligned with such indicia passageways  326  may be altered. As shown, handle  366  may include a telescopic (e.g., antenna-like) arm  367  that may be configured to extend from a first short state within gear shaft  368  to a second elongated state at least partially elongated outside of gear shaft  368  (e.g., as shown in  FIG. 8 ), which may enable handle  366  to elongate for easier use by a user and then retract within shaft  368  so as not to extend (too far) out from indicia space  383  so as to interfere with content of bottle  390  or a factory protective seal that may be initially provided by bottle  390  (e.g., across top  391 ). 
     While cap subassembly  310  may be configured to enable rotation of dial  330  in the direction of arrow R 1  about axis A within indicia space  383  with respect to closure  320  from a first orientation to a second orientation (e.g., to keep track of a medication schedule for content of bottle  390 ) by enabling user rotation of handle  366  in the direction of arrow R 2  about axis B, cap subassembly  310  may be configured to prevent rotation of dial  330  in the opposite direction of arrow R 2  about axis A. For example, as shown, gear assembly  340  may include a ratchet component  348  and base  370  may include a stopper component  372  that may be configured to interact with ratchet component  348  for preventing rotation of gear subassembly  360  in the direction of arrow R 1  and, thus, rotation of gear  350  and dial  330  in the direction of arrow R 2  while enabling rotation of gear subassembly  350  in the direction of arrow R 1 . For example, as shown, ratchet component  348  may be provided along a portion of gear subassembly  360  (e.g., adjacent a top portion of gear  362 ) and base  370  may provide stopper component  372  just adjacent ratchet component  348  in the −X direction (e.g., at the top end of an extension body  378  that may extend from a top surface  371  of the base body of base  370 ), such that a free end of stopper component  372  may enable rotation of ratchet component  348  and, thus, gear  360  in the direction of arrow R 2  about axis A and, thus gear  350  and dial  330  in the direction of arrow R 1  about axis A and at the same time prevent rotation of ratchet component  348  and, thus, gear  362  in the direction of arrow R 1  about axis A and, thus, gear  352  and dial  330  in the direction of arrow R 2  about axis A (e.g., due to the geometrical relationship between teeth or other suitable features of ratchet component  348  and the free end of stopper component  372 ). Moreover, interaction of ratchet component  348  and stopper component  372  may provide a user with an audible and/or tactile feedback to user adjustment of the indicia of assembly  300 . In some embodiments, stopper component  372  may be tensioned by a suitable amount such that the free end of stopper component  372  may exert a suitable force on ratchet component  348  for even preventing rotation of dial  330  in the direction of arrow R 1  about axis A, where such a force may be overcome by an intentional user force on handle  366  but that may not be overcome by any unintentional forces to which cap subassembly  310  may be susceptible during normal use of assembly  300 , such that components  348 / 372  may enable proper rotation of dial  330  in the direction of arrow R 1  but only if at least a certain amount of threshold force is applied to gear assembly  340  (e.g., to handle  366 ). Therefore, a stopper component may be configured to interact with a ratchet component coupled to a user gear subassembly rather than with a ratchet component coupled to a dial gear subassembly. 
     Additionally or alternatively to being provided with ratchet component and stopper component (e.g., ratchet component  348  and stopper component  372 ), gear assembly  340  may be configured to have a resting state in which movement of gear subassembly  350  may not translate into motion of gear subassembly  360  (and vice versa) and an active state in which movement of gear subassembly  350  may translate into motion of gear subassembly  360  (and vice versa). For example, as shown in  FIG. 8 , gear assembly  340  may be in a resting state, whereby a spacing distance (e.g., similar to spacing distance  141 ) may exist between gear  352  and gear  362  (e.g., along the X-axis and/or along the Z-axis of  FIG. 8 ), such that any rotation of user gear  362  in such a resting state (e.g., about axis B in the direction of arrow R 1  or arrow R 2 ) would not be translated into a rotation of dial gear  352 . In order to reconfigure gear assembly  340  from such a resting state into an active state, a user may first apply an upward force (e.g., in the +Z direction along axis B) on gear subassembly  360  (e.g., via handle  366 ), such that gear  362  may be moved upwards by the spacing distance in order to contact gear  352  (e.g., such that teeth of gear  362  may mesh with teeth of gear  352 ), and then the user may apply a rotation force (e.g., in the direction of arrow R 2  about axis B) to user gear subassembly  360  (e.g., via handle  366 ) for rotating meshed dial gear  352  in the direction of arrow R 1  about axis A. This may help prevent unintentional rotation of dial  330  and, thus, unintentional updating of exposed dial indicia  336 . 
     By positioning at least a portion of base  370  and/or gear assembly  340  within a dial space  333  within dial  330  (e.g., by positioning at least a portion of base  370  and/or at least a portion of gear assembly  340  above bottom  339  of dial  330 ), a height of indicia space  383  between top  321  and bottom  379  of assembly  300  may be shorter than a height of indicia space  183  between top  121  and bottom  179  of assembly  100  for a given height of a dial (e.g., along the Z-axis), which may reduce the overall height of the cap subassembly. 
     FIG.  9  (Assembly  400 ) 
       FIG. 9  shows another illustrative bottle container assembly  400 , which may be similar to assembly  100  of  FIGS. 1-6  but may include a flat dial and a reduced profile base. Assembly  400  of  FIG. 9  may include similar components to assembly  100  of  FIGS. 1-6 , with components of assembly  400  of  FIG. 9  being labeled with “4xx” reference labels that may correspond to the “1xx” reference labels of the labeled components of assembly  100  of  FIGS. 1-6 , where differences therebetween may be described below. As shown, assembly  400  may include a bottle  490  and a cap  410  that may be coupled to bottle  490  for forming a closed container that may safely hold content therein. For example, bottle  490  may include a bottle body that may include one or more side walls  495  that may extend from a closed bottom end (not shown) to an at least partially open top end  491  for defining an interior bottle space  493 . Bottle  490  may be configured such that a user may insert content (not shown) through open end  491  into bottle space  493  (e.g., along the −Z direction) and/or may remove content from bottle space  493  through open end  491  (e.g., along the +Z direction). Bottle  490  may be any suitable container portion that may be configured to hold any suitable content in any suitable way. Bottle  490  may be made of any suitable material or combination of materials and may be of any suitable dimensions. 
     Cap  410  may be configured to be removably coupled to bottle  490 , such that cap  410  may cover open end  491  for preventing a user from accessing bottle space  493  when cap  410  is coupled to bottle  490 , and such that cap  410  may not cover at least a portion of open end  491  for enabling a user to access bottle space  493  when cap  410  is not coupled to bottle  490 . Assembly  400  may be configured in any suitable way for enabling cap subassembly to be removably coupled to bottle  490 . As just one example, bottle  490  may include at least one cap attachment feature  492  and cap  410  may include at least one bottle attachment feature  428 , where cap attachment feature  492  and bottle attachment feature  428  may be any suitable combination of reciprocal or otherwise related features that may be configured to interact with each other for removably coupling cap  410  to bottle  490  (e.g., threads, snaps, notches, clips, location or transition fits, etc.). Bottle  490  may also include a lip  494 , which may protrude from an exterior surface of body  495  below cap attachment feature  492 , where lip  494  may be configured to suspend cap subassembly  410  by at least a certain distance above the closed end. Cap attachment feature  492  and/or lip  494  may ensure a specific relationship between cap  410  and bottle  490  when cap  410  is coupled to bottle  490 . 
     Cap  410  may include a closure  420 , a dial  430 , a gear assembly  440 , and a base  470 . Closure  420  of cap  410  may include a closure body that may include one or more side walls  425  that may extend from an at least partially closed top end  421  to an at least partially open bottom end  429  for defining an interior closure space  423 . Closure  420  may also include one or more closure indicia passageways  426  through any suitable portions of closure  420  for selectively exposing to a user one or more other portions of cap subassembly  400  (e.g., portions of dial  430 , as described below). As shown, closure indicia passageways  426  may include at least one top closure indicia passageway  426   t  that may be provided through the wall of top end  421  of closure  420 . As described below, each closure indicia passageway  426  may be a hollow opening through a wall or other portion of closure  420  or may be such an opening that may be covered by or otherwise configured to include a transparent or translucent material or any other suitable object (e.g., a magnifying glass  426   tm ) that may enable communication of information therethrough to a user of assembly  400 . Closure  420  may be made of any suitable material or combination of materials and may be of any suitable dimensions. 
     Dial  430  of cap  410  may include a dial body that may include one or more side walls that may extend from an at least partially closed top end  431  to an at least partially closed bottom end  439 . Unlike dial  230 , which may be an at least partially open shape and/or include a side dial indicia, dial  430  may be a relatively thin closed dial (e.g., along the Z-axis) with no side dial indicia, which may reduce the thickness of cap  410 . Dial  430  may include any suitable dial indicia  436  on any suitable portions of dial  430  for selective display to a user of assembly  400 . As shown, dial indicia  436  may include top dial indicia  436   t  that may be provided on an exterior surface of top end  431  of dial  430 , and/or bottom dial indicia  436   b  that may be provided on an exterior surface of bottom end  439 . Dial  430  may be configured to fit at least partially within closure space  423 , such that dial  430  may be moved within closure space  423  with respect to closure  420  for selectively aligning different dial indicia  436  of dial  430  with a closure indicia passageway  426  of closure  420  and/or a base indicia passageway  476  of base  470  (described below). Dial  430  may be made of any suitable material or combination of materials and may be of any suitable dimensions. 
     Base  470  of cap  410  may include a base body that may include one or more side walls  475  that may extend from an at least partially closed top end  471  to an at least partially closed bottom end  479 . Base  470  may be configured to be coupled (e.g., permanently or removably) to closure  420 , such that, for example, base  470  and closure  420  may together define at least a portion of an indicia space  483  within which dial  430  may be positioned. For example, base  470  may include at least one closure attachment feature (e.g., the shape of an exterior surface of side wall(s)  475  of base  470 ) and closure  420  may include at least one base attachment feature  424  (e.g., one or more grooves or female threads protruding from an interior surface of closure  420 ), where base  470  may snap into or otherwise fit base  470  within base attachment feature  424  for securing base  470  within closure space  423 , which may thereby define a reduced indicia space  483  between closure  420  and base  470 . Base attachment feature  424  may be positioned above bottle attachment feature  428  within closure space  423  of closure  420  such that base  470  may be coupled to closure  420  while still enabling bottle attachment feature  428  to removably couple closure  420  to bottle  490 . While closure space  423  may be defined by the interior surface(s) of side wall(s)  425 , top end  421 , and bottom end  429  of closure  420 , indicia space  483  may be defined by the interior surface(s) of side wall(s)  425  and top end  421  of closure  420  as well as by base  470 , such that indicia space  483  may be a portion of closure space  423 . Thus, base  470  may be configured to fit at least partially within closure space  423 , such that base  470  may define at least a portion of the bottom of indicia space  483 . Base  470  may be made of any suitable material or combination of materials and may be of any suitable dimensions. Dial  430  may be at least partially positioned within indicia space  483  when base  470  is coupled to closure  420 . Base  470  may have less material than base  270  or base  370 , and a thickness of base  470  (e.g., along the Z-axis) may be substantially constant while portions of base  470  may run adjacently along bottom  439  of dial  430  (e.g., to support dial  430 ). 
     Gear assembly  440  of cap  410  may be at least partially positioned within indicia space  483  along with dial  430 , and gear assembly  440  may be configured to selectively move dial  430  within indicia space  483  with respect to closure  420  for selectively aligning different dial indicia  436  with a closure indicia passageway  426  of closure  420 . Gear assembly  440  may include one or more gears that may be configured to translate a user motion that may be applied to a first portion of gear assembly  440  into movement of dial  430  with indicia space  483  (e.g., rotation of dial  430  about an axis A along a Z-axis). As shown, gear assembly  440  may include an upper or dial gear subassembly  450  and a lower or user gear subassembly  460 . Dial gear subassembly  450  may include an upper or dial cogwheel or gear  452  and, in some embodiments, an upper or dial gear shaft  458  that may extend away from gear  452  along an axis of rotation of gear  452  (e.g., axis A along a Z-axis). User gear subassembly  460  may include a lower or user cogwheel or gear  462  and, in some embodiments, a lower or user gear shaft  468  that may extend away from gear  462  along an axis of rotation of gear  462  (e.g., axis B along a Z-axis that may be parallel to axis A). User gear subassembly  460  may also include a user handle  466  that may be coupled to a portion of gear  462  (e.g., at an end of gear shaft  468 ), such that a user may apply a user force or motion to handle  466  for rotating gear  462 . Gear assembly  440  may be configured such that rotation of gear  462  may be configured to rotate or otherwise translate gear  452 , which may be configured to rotate or otherwise translate dial  430  with respect to closure  420  within indicia space  483 . For example, as shown, gear  462  may include teeth or cogs or any other suitable mechanical feature that may mesh with teeth or cogs or any other suitable mechanical feature of gear  452  to transmit torque therebetween within gear assembly  440  (e.g., as a transmission or gearbox). 
     Base  470  may be configured to support at least a portion of gear assembly  440  and/or dial  430  within indicia space  483  when base  470  is coupled to closure  420 . For example, as shown, at least a portion of user gear subassembly  460  (e.g., a bottom portion of gear  462 ) may be configured to rest against base  470  (e.g., against an exterior surface of top wall  471  of base  470 ). A user gear shaft opening  477  may be provided through base  470  (e.g., between top wall  471  and bottom wall  479 ) for enabling at least a portion of user gear shaft  468  and/or user handle  466  to extend therethrough from indicia space  483  to at least a portion of closure space  423  and/or bottle space  493  or for at least enabling a portion of gear subassembly  460  to be accessible therethrough, such that a portion of gear assembly  440  may be accessible to a user when cap  410  is not coupled to bottle  490  (e.g., when a user unscrews cap  410  from bottle  490  for accessing contents  497 ). Such accessibility to a portion of gear subassembly  460  by a user external to indicia space  483  (e.g., via user gear shaft opening  477  of base  470 ) may enable a user of assembly  400  to apply a user force or motion to handle  466  for rotating gear  462 . Alternatively or additionally, in some embodiments, user gear shaft opening  477  of base  470  may at least partially define an axis of rotation of user gear  462  and/or may otherwise limit at least a portion of a path along which at least a portion of user gear subassembly  460  may travel (e.g., by preventing or limiting movement of gear subassembly  460  along the X-axis and/or along the Y-axis within indicia space  483 ). For example, as shown, user gear  462  may be configured to rotate about an axis B, and gear shaft  468  may extend away from gear  462  along axis B, such that gear shaft opening  477  may align with axis B. Additionally or alternatively, as shown, at least a portion of dial gear subassembly  450  (e.g., a top portion of gear  452 ) may be coupled to dial  430  (e.g., to bottom wall  439  of dial  430 ), such that movement of gear subassembly  450  may provide movement of dial  430  (e.g., rotational movement about axis A). In some embodiments, a dial gear shaft opening  473  may be provided through at least a portion of base  470  (e.g., through top wall  471 ), where opening  473  may at least partially define an axis of rotation of dial gear  452  and/or may otherwise limit at least a portion of a path along which at least a portion of dial gear subassembly  450  may travel (e.g., by preventing or limiting movement of gear subassembly  450  along the X-axis and/or along the Y-axis within indicia space  483 ). For example, as shown, dial gear  452  may be configured to rotate about an axis A, and gear shaft  458  may extend away from gear  452  along axis A, such that gear shaft opening  473  may align with axis A. However, in some embodiments, gear shaft opening  473  and/or gear shaft  458  may not be necessary and other features of assembly  400  may define axis A about which gear  452  may rotate. For example, the positioning of base  470 , gear subassembly  460 , and dial  430  within indicia space  483  may limit the manner in which gear subassembly  450  may move within indicia space  483  (e.g., only to movement about axis A). In some embodiments, as shown in  FIG. 9 , an interior surface of top end  421  of closure  420  may include a dial movement feature  427  and an exterior surface of top end  431  of dial  430  may include a closure movement feature  437 , where such features  427  and  437  may interact with one another to at least partially define an axis of rotation of dial  430  with respect to closure  420  (e.g., axis A) or otherwise aid or limit such movement (e.g., by preventing or limiting movement of dial  430  along the X-axis and/or along the Y-axis within indicia space  483 ), for example, where feature  437  may be a nub that may extend into a cut out or notch  427 . In some embodiments, the thickness of the wall of top end  431  of dial  430  along the Z-axis combined with the thickness of gear assembly  440  along the Z-axis may be substantially equal to or slightly less than a thickness of indicia space  483  along the Z-axis, such that dial  430  and/or gear assembly  440  may be prevented or limited with respect to movement along the Z-axis. 
     As just one example of use, a user may interact with handle  466  of user gear subassembly  460 , as may be accessible to a user through opening  477  of base  470 , for rotating gear shaft  468  and/or gear  462  in the direction of arrow R 2  about axis B, which may in turn rotate gear  452  of dial subassembly  450  in the direction of arrow R 1  about axis A, which may in turn rotate dial  430  in the direction of arrow R 1  about axis A. Such rotation of dial  430  in the direction of arrow R 1  about axis A within indicia space  483  with respect to closure  420  may alter the particular portion of dial  430  and, thus, the particular portion of dial indicia  436  that may be aligned with a particular closure indicia passageway  426 , which may alter what information may be provided to a user of assembly  400  by that particular portion of dial indicia  436 . For example, as shown in  FIG. 9 , when dial  430  is at a first particular orientation with respect to closure  420  and base  470  within indicia space  483 , a first indication of top dial indicia  436   t  may be aligned with and visible through indicia passageway  426   t  and/or a first indication of bottom dial indicia  436   b  may be aligned with and visible through indicia passageway  476  of base  470 . However, when dial  430  is rotated in the direction of arrow R 1  about axis A within indicia space  483  with respect to closure  420  from such a first orientation to a second orientation, the particular portion of dial  430  and, thus, the particular portion of dial indicia  436  that may be aligned with such indicia passageways  426 / 476  may be altered. As shown, handle  466  may include a rotatable arm  467  about a pivot  465  of shaft  468  that may be configured to rotate from a first short state (e.g., with respect to the Z-axis) such that arm  467  may extend up towards base  470  (e.g., as shown in  FIG. 9 ) to a second elongated state (e.g., with respect to the Z-axis), which may enable handle  466  to elongate for easier use by a user and then rotatably retract so as not to extend (e.g., too far) out away from base  470  and/or indicia space  483  so as to interfere with content of bottle  490  or a factory protective seal that may be initially provided by bottle  490  (e.g., across top  491 ). Such rotation of arm  467  with respect to shaft  468  may enable easier rotation of shaft  468  about axis B through rotation of the free end of arm  467  about axis B and within an X-Y plane, which may provide a user with additional leverage than may be provided by a free end of shaft  468 . 
     While cap subassembly  410  may be configured to enable rotation of dial  430  in the direction of arrow R 1  about axis A within indicia space  483  with respect to closure  420  from a first orientation to a second orientation (e.g., to keep track of a medication schedule for content of bottle  490 ) by enabling user rotation of handle  466  in the direction of arrow R 2  about axis B, cap subassembly  410  may be configured to prevent rotation of dial  430  in the opposite direction of arrow R 2  about axis A. For example, as shown, gear assembly  440  may include a ratchet component  442  and base  470  may include a stopper component  472  that may be configured to interact with ratchet component  442  for preventing rotation of gear subassembly  450  in the direction of arrow R 2  while enabling rotation of gear subassembly  450  in the direction of arrow R 1 . For example, as shown, ratchet component  442  may be provided along a portion of gear subassembly  450  (e.g., adjacent a top portion of gear  452 ) and base  470  may provide stopper component  472  just adjacent ratchet component  442  in the +X direction (e.g., as an extension of a portion of top surface  471  of the base body of base  470 ), such that a free end of stopper component  472  may enable rotation of ratchet component  442  and, thus, gear  450  and dial  430  in the direction of arrow R 1  about axis A and at the same time prevent rotation of ratchet component  442  and, thus, gear  452  and dial  430  in the direction of arrow R 2  about axis A (e.g., due to the geometrical relationship between teeth or other suitable features of ratchet component  442  and the free end of stopper component  472 ). Moreover, interaction of ratchet component  442  and stopper component  472  may provide a user with an audible and/or tactile feedback to user adjustment of the indicia of assembly  400 . In some embodiments, stopper component  472  may be tensioned by a suitable amount such that the free end of stopper component  472  may exert a suitable force on ratchet component  442  for even preventing rotation of dial  430  in the direction of arrow R 1  about axis A, where such a force may be overcome by an intentional user force on handle  466  but that may not be overcome by any unintentional forces to which cap subassembly  410  may be susceptible during normal use of assembly  400 , such that components  442 / 472  may enable proper rotation of dial  430  in the direction of arrow R 1  but only if at least a certain amount of threshold force is applied to gear assembly  440  (e.g., to handle  466 ). 
     Additionally or alternatively to being provided with ratchet component and stopper component (e.g., ratchet component  442  and stopper component  472 ), gear assembly  440  may be configured to have a resting state in which movement of gear subassembly  450  may not translate into motion of gear subassembly  460  (and vice versa) and an active state in which movement of gear subassembly  450  may translate into motion of gear subassembly  460  (and vice versa). For example, as shown in  FIG. 9 , gear assembly  440  may be in a resting state, whereby a spacing distance (e.g., similar to spacing distance  141 ) may exist between gear  452  and gear  462  (e.g., along the X-axis and/or along the Z-axis of  FIG. 9 ), such that any rotation of user gear  462  in such a resting state (e.g., about axis B in the direction of arrow R 1  or arrow R 2 ) would not be translated into a rotation of dial gear  452 . In order to reconfigure gear assembly  440  from such a resting state into an active state, a user may first apply an upward force (e.g., in the +Z direction along axis B) on gear subassembly  460  (e.g., via handle  466 ), such that gear  462  may be moved upwards by the spacing distance in order to contact gear  452  (e.g., such that teeth of gear  462  may mesh with teeth of gear  452 ), and then the user may apply a rotation force (e.g., in the direction of arrow R 2  about axis B) to user gear subassembly  460  (e.g., via handle  466 ) for rotating meshed dial gear  452  in the direction of arrow R 1  about axis A. This may help prevent unintentional rotation of dial  430  and, thus, unintentional updating of exposed dial indicia  436 . 
     By reducing the thickness of dial  430  while also minimizing the thickness of indicia spacing  483  to only that which may be needed for gear assembly  430 , a height of indicia space  483  between top  421  and bottom  479  of assembly  400  may be shorter than a height of indicia space  183  between top  121  and bottom  179  of assembly  100 , while a portion of that reduced height may be used to store a portion of a handle  466  (e.g., portion  467 ) when in a non-use state. 
     FIG.  10  (Assembly  500 ) 
       FIG. 10  shows another illustrative bottle container assembly  500 , which may be similar to assembly  100  of  FIGS. 1-6  but may include a flat dial and a reduced profile base. Assembly  500  of  FIG. 10  may include similar components to assembly  100  of  FIGS. 1-6 , with components of assembly  500  of  FIG. 10  being labeled with “5xx” reference labels that may correspond to the “1xx” reference labels of the labeled components of assembly  100  of  FIGS. 1-6 , where differences therebetween may be described below. As shown, assembly  500  may include a bottle  590  and a cap  510  that may be coupled to bottle  590  for forming a closed container that may safely hold content therein. For example, bottle  590  may include a bottle body that may include one or more side walls  595  that may extend from a closed bottom end (not shown) to an at least partially open top end  591  for defining an interior bottle space  593 . Bottle  590  may be configured such that a user may insert content (not shown) through open end  591  into bottle space  593  (e.g., along the −Z direction) and/or may remove content from bottle space  593  through open end  591  (e.g., along the +Z direction). Bottle  590  may be any suitable container portion that may be configured to hold any suitable content in any suitable way. Bottle  590  may be made of any suitable material or combination of materials and may be of any suitable dimensions. 
     Cap  510  may be configured to be removably coupled to bottle  590 , such that cap  510  may cover open end  591  for preventing a user from accessing bottle space  593  when cap  510  is coupled to bottle  590 , and such that cap  510  may not cover at least a portion of open end  591  for enabling a user to access bottle space  593  when cap  510  is not coupled to bottle  590 . Assembly  500  may be configured in any suitable way for enabling cap subassembly to be removably coupled to bottle  590 . As just one example, bottle  590  may include at least one cap attachment feature  592  and cap  510  may include at least one bottle attachment feature  528 , where cap attachment feature  592  and bottle attachment feature  528  may be any suitable combination of reciprocal or otherwise related features that may be configured to interact with each other for removably coupling cap  510  to bottle  590  (e.g., threads, snaps, notches, clips, location or transition fits, etc.). Bottle  590  may also include a lip  594 , which may protrude from an exterior surface of body  595  below cap attachment feature  592 , where lip  594  may be configured to suspend cap subassembly  510  by at least a certain distance above the closed end. Cap attachment feature  592  and/or lip  594  may ensure a specific relationship between cap  510  and bottle  590  when cap  510  is coupled to bottle  590 . 
     Cap  510  may include a closure  520 , a dial  530 , a gear assembly  540 , and a base  570 . Closure  520  of cap  510  may include a closure body that may include one or more side walls  525  that may extend from an at least partially closed top end  521  to an at least partially open bottom end  529  for defining an interior closure space  523 . Closure  520  may also include one or more closure indicia passageways  526  through any suitable portions of closure  520  for selectively exposing to a user one or more other portions of cap subassembly  500  (e.g., portions of dial  530 , as described below). As shown, closure indicia passageways  526  may include at least one top closure indicia passageway  526   t  that may be provided through the wall of top end  521  of closure  520 . As described below, each closure indicia passageway  526  may be a hollow opening through a wall or other portion of closure  520  or may be such an opening that may be covered by or otherwise configured to include a transparent or translucent material or any other suitable object (e.g., a magnifying glass  526   tm ) that may enable communication of information therethrough to a user of assembly  500 . Closure  520  may be made of any suitable material or combination of materials and may be of any suitable dimensions. 
     Dial  530  of cap  510  may include a dial body that may include one or more side walls that may extend from an at least partially closed top end  531  to an at least partially closed bottom end  539 . Unlike dial  230 , which may be an at least partially open shape and/or include a side dial indicia, dial  530  may be a relatively thin closed dial (e.g., along the Z-axis) with no side dial indicia, which may reduce the thickness of cap  510 . Dial  530  may include any suitable dial indicia  536  on any suitable portions of dial  530  for selective display to a user of assembly  500 . As shown, dial indicia  536  may include top dial indicia  536   t  that may be provided on an exterior surface of top end  531  of dial  530 , and/or bottom dial indicia (not shown) that may be provided on an exterior surface of bottom end  539 . Dial  530  may be configured to fit at least partially within closure space  523 , such that dial  530  may be moved within closure space  523  with respect to closure  520  for selectively aligning different dial indicia  536  of dial  530  with a closure indicia passageway  526  of closure  520  and/or a base indicia passageway of base  570  (not shown). Dial  530  may be made of any suitable material or combination of materials and may be of any suitable dimensions. Unlike dial  130 , dial  530  may be configured to be coupled (e.g., permanently or removably) to closure  520 , such that, for example, closure  520  may prevent dial  530  from moving (e.g., along the Z-axis). For example, dial  530  may include at least one closure attachment feature (e.g., the shape of an exterior surface of side wall(s)  535  of dial  530 ) and closure  520  may include at least one dial attachment feature  522  (e.g., one or more grooves or female threads protruding from an interior surface of closure  520 ), where dial  530  may snap into or otherwise fit dial  530  within dial attachment feature  522  for securing dial  530  within closure space  523 . Dial attachment feature  522  may be positioned above both base attachment feature  524  (described below) and bottle attachment feature  528  within closure space  523  of closure  520  such that dial  530  and base  570  may be coupled to closure  520  while still enabling bottle attachment feature  528  to removably couple closure  520  to bottle  590 . 
     Base  570  of cap  510  may include a base body that may include one or more side walls  575  that may extend from an at least partially closed top end  571  to an at least partially closed bottom end  579 . Base  570  may be configured to be coupled (e.g., permanently or removably) to closure  520 , such that, for example, base  570  and closure  520  may together define at least a portion of an indicia space  583  within which dial  530  may be positioned. For example, base  570  may include at least one closure attachment feature (e.g., the shape of an exterior surface of side wall(s)  575  of base  570 ) and closure  520  may include at least one base attachment feature  524  (e.g., one or more grooves or female threads protruding from an interior surface of closure  520 ), where base  570  may snap into or otherwise fit base  570  within base attachment feature  524  for securing base  570  within closure space  523 , which may thereby define a reduced indicia space  583  between closure  520  and base  570 . Base attachment feature  524  may be positioned above bottle attachment feature  528  within closure space  523  of closure  520  such that base  570  may be coupled to closure  520  while still enabling bottle attachment feature  528  to removably couple closure  520  to bottle  590 . While closure space  523  may be defined by the interior surface(s) of side wall(s)  525 , top end  521 , and bottom end  529  of closure  520 , indicia space  583  may be defined by the interior surface(s) of side wall(s)  525  and top end  521  of closure  520  as well as by base  570 , such that indicia space  583  may be a portion of closure space  523 . Thus, base  570  may be configured to fit at least partially within closure space  523 , such that base  570  may define at least a portion of the bottom of indicia space  583 . Base  570  may be made of any suitable material or combination of materials and may be of any suitable dimensions. Dial  530  may be at least partially positioned within indicia space  583  when base  570  is coupled to closure  520 . Base  570  may have less material than base  270  or base  370 , and a thickness of base  570  (e.g., along the Z-axis) may be substantially constant while portions of base  570  may run adjacently along bottom  539  of dial  530  (e.g., to support dial  530 ). 
     Gear assembly  540  of cap  510  may be at least partially positioned within indicia space  583  along with dial  530 , and gear assembly  540  may be configured to selectively move dial  530  within indicia space  583  with respect to closure  520  for selectively aligning different dial indicia  536  with a closure indicia passageway  526  of closure  520 . Gear assembly  540  may include one or more gears that may be configured to translate a user motion that may be applied to a first portion of gear assembly  540  into movement of dial  530  with indicia space  583  (e.g., rotation of dial  530  about an axis A along a Z-axis). As shown, gear assembly  540  may include an upper or dial gear subassembly  550  and a lower or user gear subassembly  560 . Dial gear subassembly  550  may include an upper or dial cogwheel or gear  552  and, in some embodiments, an upper or dial gear shaft  558  that may extend away from gear  552  along an axis of rotation of gear  552  (e.g., axis A along a Z-axis). User gear subassembly  560  may include a lower or user cogwheel or gear  562  and, in some embodiments, a lower or user gear shaft  568  that may extend away from gear  562  along an axis of rotation of gear  562  (e.g., axis B along a Z-axis that may be parallel to axis A). User gear subassembly  560  may also include a user handle  566  that may be coupled to a portion of gear  562  (e.g., at an end of gear shaft  568 ), such that a user may apply a user force or motion to handle  566  for rotating gear  562 . Gear assembly  540  may be configured such that rotation of gear  562  may be configured to rotate or otherwise translate gear  552 , which may be configured to rotate or otherwise translate dial  530  with respect to closure  520  within indicia space  583 . For example, as shown, gear  562  may include teeth or cogs or any other suitable mechanical feature that may mesh with teeth or cogs or any other suitable mechanical feature of gear  552  to transmit torque therebetween within gear assembly  540  (e.g., as a transmission or gearbox). 
     Base  570  may be configured to support at least a portion of gear assembly  540  and/or dial  530  within indicia space  583  when base  570  is coupled to closure  520 . For example, as shown, at least a portion of user gear subassembly  560  (e.g., a bottom portion of gear  562 ) may be configured to rest against base  570  (e.g., against an exterior surface of top wall  571  of base  570 ). A user gear shaft opening  577  may be provided through base  570  (e.g., between top wall  571  and bottom wall  579 ) for enabling at least a portion of user gear shaft  568  and/or user handle  566  to extend therethrough from indicia space  583  to at least a portion of closure space  523  and/or bottle space  593  or for at least enabling a portion of gear subassembly  560  to be accessible therethrough, such that a portion of gear assembly  540  may be accessible to a user when cap  510  is not coupled to bottle  590  (e.g., when a user unscrews cap  510  from bottle  590  for accessing contents  597 ). Such accessibility to a portion of gear subassembly  560  by a user external to indicia space  583  (e.g., via user gear shaft opening  577  of base  570 ) may enable a user of assembly  500  to apply a user force or motion to handle  566  for rotating gear  562 . Alternatively or additionally, in some embodiments, user gear shaft opening  577  of base  570  may at least partially define an axis of rotation of user gear  562  and/or may otherwise limit at least a portion of a path along which at least a portion of user gear subassembly  560  may travel (e.g., by preventing or limiting movement of gear subassembly  560  along the X-axis and/or along the Y-axis within indicia space  583 ). For example, as shown, user gear  562  may be configured to rotate about an axis B, and gear shaft  568  may extend away from gear  562  along axis B, such that gear shaft opening  577  may align with axis B. Additionally or alternatively, as shown, at least a portion of dial gear subassembly  550  (e.g., a top portion of gear  552 ) may be coupled to dial  530  (e.g., to bottom wall  539  of dial  530 ), such that movement of gear subassembly  550  may provide movement of dial  530  (e.g., rotational movement about axis A). In some embodiments, a dial gear shaft opening  573  may be provided through at least a portion of base  570  (e.g., through top wall  571 ), where opening  573  may at least partially define an axis of rotation of dial gear  552  and/or may otherwise limit at least a portion of a path along which at least a portion of dial gear subassembly  550  may travel (e.g., by preventing or limiting movement of gear subassembly  550  along the X-axis and/or along the Y-axis within indicia space  583 ). For example, as shown, dial gear  552  may be configured to rotate about an axis A, and gear shaft  558  may extend away from gear  552  along axis A, such that gear shaft opening  573  may align with axis A. However, in some embodiments, gear shaft opening  573  and/or gear shaft  558  may not be necessary and other features of assembly  500  may define axis A about which gear  552  may rotate. For example, the positioning of base  570 , gear subassembly  560 , and dial  530  within indicia space  583  may limit the manner in which gear subassembly  550  may move within indicia space  583  (e.g., only to movement about axis A). In some embodiments, as shown in  FIG. 10 , an interior surface of top end  521  of closure  520  may include a dial movement feature  527  and an exterior surface of top end  531  of dial  530  may include a closure movement feature  537 , where such features  527  and  537  may interact with one another to at least partially define an axis of rotation of dial  530  with respect to closure  520  (e.g., axis A) or otherwise aid or limit such movement (e.g., by preventing or limiting movement of dial  530  along the X-axis and/or along the Y-axis within indicia space  583 ), for example, where feature  537  may be a nub that may extend into a cut out or notch  527 . In some embodiments, the thickness of the wall of top end  531  of dial  530  along the Z-axis combined with the thickness of gear assembly  540  along the Z-axis may be substantially equal to or slightly less than a thickness of indicia space  583  along the Z-axis, such that dial  530  and/or gear assembly  540  may be prevented or limited with respect to movement along the Z-axis. 
     As just one example of use, a user may interact with handle  566  of user gear subassembly  560 , as may be accessible to a user through opening  577  of base  570 , for rotating gear shaft  568  and/or gear  562  in the direction of arrow R 2  about axis B, which may in turn rotate gear  552  of dial subassembly  550  in the direction of arrow R 1  about axis A, which may in turn rotate dial  530  in the direction of arrow R 1  about axis A. Such rotation of dial  530  in the direction of arrow R 1  about axis A within indicia space  583  with respect to closure  520  may alter the particular portion of dial  530  and, thus, the particular portion of dial indicia  536  that may be aligned with a particular closure indicia passageway  526 , which may alter what information may be provided to a user of assembly  500  by that particular portion of dial indicia  536 . For example, as shown in  FIG. 10 , when dial  530  is at a first particular orientation with respect to closure  520  and base  570  within indicia space  583 , a first indication of top dial indicia  536   t  may be aligned with and visible through indicia passageway  526   t . However, when dial  530  is rotated in the direction of arrow R 1  about axis A within indicia space  583  with respect to closure  520  from such a first orientation to a second orientation, the particular portion of dial  530  and, thus, the particular portion of dial indicia  536  that may be aligned with such indicia passageway  526  may be altered. As shown, handle  566  may include a flexible arm that may be configured to bend or flex in any suitable direction and/or to any suitable shape (e.g., with respect to the Z-axis) such that handle  566  may extend up towards or at least parallel to base  570  (e.g., as shown in  FIG. 10 ) and then may be bent to a second elongated state (e.g., with respect to the Z-axis), which may enable handle  566  to extend away from base  570  for easier use by a user and then bend towards or along base  570  so as not to extend (too far) out away from base  570  and/or indicia space  583  so as to interfere with content of bottle  590  or a factory protective seal that may be initially provided by bottle  590  (e.g., across top  591 ). 
     While cap subassembly  510  may be configured to enable rotation of dial  530  in the direction of arrow R 1  about axis A within indicia space  583  with respect to closure  520  from a first orientation to a second orientation (e.g., to keep track of a medication schedule for content of bottle  590 ) by enabling user rotation of handle  566  in the direction of arrow R 2  about axis B, cap subassembly  510  may be configured to prevent rotation of dial  530  in the opposite direction of arrow R 2  about axis A. For example, as shown, gear assembly  540  may include a ratchet component  542  and base  570  may include a stopper component  572  that may be configured to interact with ratchet component  542  for preventing rotation of gear subassembly  550  in the direction of arrow R 2  while enabling rotation of gear subassembly  550  in the direction of arrow R 1 . For example, as shown, ratchet component  542  may be provided along a portion of gear subassembly  550  (e.g., adjacent a top portion of gear  552 ) and base  570  may provide stopper component  572  just adjacent ratchet component  542  in the +X direction (e.g., as an extension of a portion of top surface  571  of the base body of base  570 ), such that a free end of stopper component  572  may enable rotation of ratchet component  542  and, thus, gear  550  and dial  530  in the direction of arrow R 1  about axis A and at the same time prevent rotation of ratchet component  542  and, thus, gear  552  and dial  530  in the direction of arrow R 2  about axis A (e.g., due to the geometrical relationship between teeth or other suitable features of ratchet component  542  and the free end of stopper component  572 ). Moreover, interaction of ratchet component  542  and stopper component  572  may provide a user with an audible and/or tactile feedback to user adjustment of the indicia of assembly  500 . In some embodiments, stopper component  572  may be tensioned by a suitable amount such that the free end of stopper component  572  may exert a suitable force on ratchet component  542  for even preventing rotation of dial  530  in the direction of arrow R 1  about axis A, where such a force may be overcome by an intentional user force on handle  566  but that may not be overcome by any unintentional forces to which cap subassembly  510  may be susceptible during normal use of assembly  500 , such that components  542 / 572  may enable proper rotation of dial  530  in the direction of arrow R 1  but only if at least a certain amount of threshold force is applied to gear assembly  540  (e.g., to handle  566 ). 
     Additionally or alternatively to being provided with ratchet component and stopper component (e.g., ratchet component  542  and stopper component  572 ), gear assembly  540  may be configured to have a resting state in which movement of gear subassembly  550  may not translate into motion of gear subassembly  560  (and vice versa) and an active state in which movement of gear subassembly  550  may translate into motion of gear subassembly  560  (and vice versa). For example, as shown in  FIG. 10 , gear assembly  540  may be in a resting state, whereby a spacing distance (e.g., similar to spacing distance  141 ) may exist between gear  552  and gear  562  (e.g., along the X-axis and/or along the Z-axis of  FIG. 10 ), such that any rotation of user gear  562  in such a resting state (e.g., about axis B in the direction of arrow R 1  or arrow R 2 ) would not be translated into a rotation of dial gear  552 . In order to reconfigure gear assembly  540  from such a resting state into an active state, a user may first apply an upward force (e.g., in the +Z direction along axis B) on gear subassembly  560  (e.g., via handle  566 ), such that gear  562  may be moved upwards by the spacing distance in order to contact gear  552  (e.g., such that teeth of gear  562  may mesh with teeth of gear  552 ), and then the user may apply a rotation force (e.g., in the direction of arrow R 2  about axis B) to user gear subassembly  560  (e.g., via handle  566 ) for rotating meshed dial gear  552  in the direction of arrow R 1  about axis A. This may help prevent unintentional rotation of dial  530  and, thus, unintentional updating of exposed dial indicia  536 . 
     By reducing the thickness of dial  530  while also minimizing the thickness of indicia spacing  583  to only that which may be needed for gear assembly  530 , a height of indicia space  583  between top  521  and bottom  579  of assembly  500  may be shorter than a height of indicia space  183  between top  121  and bottom  179  of assembly  100 , while a portion of that reduced height may be used to store a portion of a handle  566  (e.g., a free end of handle  566 ) when in a non-use state. 
     FIG.  11  and FIG.  12  (Assembly  600 ) 
       FIGS. 11 and 12  show another illustrative bottle container assembly  600 , which may be similar to assembly  100  of  FIGS. 1-6  but may include a movable lid for enabling replacement of a dial or at least of the dial indicia of a dial. Assembly  600  of  FIGS. 11 and 12  may include similar components to assembly  100  of  FIGS. 1-6 , with components of assembly  600  of  FIGS. 11 and 12  being labeled with “6xx” reference labels that may correspond to the “1xx” reference labels of the labeled components of assembly  100  of  FIGS. 1-6 , where differences therebetween may be described below. As shown, assembly  600  may include a bottle  690  and a cap  610  that may be coupled to bottle  690  for forming a closed container that may safely hold content therein. For example, bottle  690  may include a bottle body that may include one or more side walls  695  that may extend from a closed bottom end  699  to an at least partially open top end  691  for defining an interior bottle space  693 . Bottle  690  may be configured such that a user may insert content  697  through open end  691  into bottle space  693  (e.g., along the −Z direction) and/or may remove content  697  from bottle space  693  through open end  691  (e.g., along the ±Z direction). Bottle  690  may be any suitable container portion that may be configured to hold any suitable content  697  in any suitable way. Bottle  690  may be made of any suitable material or combination of materials and may be of any suitable dimensions. 
     Cap  610  may be configured to be removably coupled to bottle  690 , such that cap  610  may cover open end  691  for preventing a user from accessing bottle space  693  when cap  610  is coupled to bottle  690 , and such that cap  610  may not cover at least a portion of open end  691  for enabling a user to access bottle space  693  when cap  610  is not coupled to bottle  690 . Assembly  600  may be configured in any suitable way for enabling cap subassembly to be removably coupled to bottle  690 . As just one example, bottle  690  may include at least one cap attachment feature  692  and cap  610  may include at least one bottle attachment feature  628 , where cap attachment feature  692  and bottle attachment feature  628  may be any suitable combination of reciprocal or otherwise related features that may be configured to interact with each other for removably coupling cap  610  to bottle  690  (e.g., threads, snaps, notches, clips, location or transition fits, etc.). Bottle  690  may also include a lip  694 , which may protrude from an exterior surface of body  695  below cap attachment feature  692 , where lip  694  may be configured to suspend cap subassembly  610  by at least a certain distance above the closed end. Cap attachment feature  692  and/or lip  694  may ensure a specific relationship between cap  610  and bottle  690  when cap  610  is coupled to bottle  690 . 
     Cap  610  may include a closure  620 , a dial  630 , a gear assembly  640 , and a base  670 . Closure  620  of cap  610  may include a closure body that may include one or more side walls  625  that may extend from an at least partially closed top end  621  to an at least partially open bottom end  629  for defining an interior closure space  623 . Closure  620  may also include one or more closure indicia passageways  626  through any suitable portions of closure  620  for selectively exposing to a user one or more other portions of cap subassembly  600  (e.g., portions of dial  630 , as described below). As shown, closure indicia passageways  626  may include at least one top closure indicia passageway  626   t  that may be provided through the wall of top end  621  of closure  620 . As described below, each closure indicia passageway  626  may be a hollow opening through a wall or other portion of closure  620  or may be such an opening that may be covered by or otherwise configured to include a transparent or translucent material or any other suitable object (e.g., a magnifying glass  626   tm ) that may enable communication of information therethrough to a user of assembly  600 . Closure  620  may be made of any suitable material or combination of materials and may be of any suitable dimensions. Closure  620  may also include a hinge  620 H or any other suitable mechanism that may enable at least a portion of top end  621  of closure  620  to be rotated or otherwise moved away from closure space  623  (e.g., from an X-Y plane to a Y-Z plane of  FIG. 11 ), such that a user may have access to at least a portion of closure space  623  (e.g., in the −Z direction), which may enable the user to replace dial  630  or any dial indicia thereon. Closure  620  may include one or more attachment features  627 A at top end  621  for enabling removable coupling of top end  621  with one or more attachment features  627 B along a top of a side wall  625  of closure  620 . 
     Dial  630  of cap  610  may include a dial body that may include one or more side walls that may extend from an at least partially closed top end  631  to an at least partially closed bottom end  639 . Unlike dial  230 , which may be an at least partially open shape and/or include a side dial indicia, dial  630  may be a relatively thin closed dial (e.g., along the Z-axis) with no side dial indicia, which may reduce the thickness of cap  610 . Dial  630  may include any suitable dial indicia  636  that may be positioned on any suitable portions of dial  630  for selective display to a user of assembly  600 . As shown, dial indicia  636  may include top dial indicia  636   t  that may be provided on an exterior surface of top end  631  of dial  630 , and/or bottom dial indicia (not shown) that may be provided on an exterior surface of bottom end  639 . Dial  630  may be configured to fit at least partially within closure space  623 , such that dial  630  may be moved within closure space  623  with respect to closure  620  for selectively aligning different dial indicia  636  of dial  630  with a closure indicia passageway  626  of closure  620  and/or a base indicia passageway of base  670  (not shown). Dial  630  may be made of any suitable material or combination of materials and may be of any suitable dimensions. Unlike dial  130 , dial  630  may be configured to be coupled (e.g., permanently or removably) to closure  620 , such that, for example, closure  620  may prevent dial  630  from moving (e.g., along the Z-axis). For example, dial  630  may include at least one closure attachment feature (e.g., the shape of an exterior surface of side wall(s)  635  of dial  630 ) and closure  620  may include at least one dial attachment feature  622  (e.g., one or more grooves or female threads protruding from an interior surface of closure  620 ), where dial  630  may snap into or otherwise fit dial  630  within dial attachment feature  622  for securing dial  630  within closure space  623 . Dial attachment feature  622  may be positioned above both base attachment feature  624  (described below) and bottle attachment feature  628  within closure space  623  of closure  620  such that dial  630  and base  670  may be coupled to closure  620  while still enabling bottle attachment feature  628  to removably couple closure  620  to bottle  690 . In some embodiments, an upper portion of attachment feature  628  may not be provided such that dial  630  may be easily removed from closure space  623  (e.g., in the +Z direction by a user when top  621  provides access to closure space  623 ), which may enable a user to replace dial  630  and/or at least replace indicia on all sides of dial  630 . 
     Base  670  of cap  610  may include a base body that may include one or more side walls  675  that may extend from an at least partially closed top end  671  to an at least partially closed bottom end  679 . Base  670  may be configured to be coupled (e.g., permanently or removably) to closure  620 , such that, for example, base  670  and closure  620  may together define at least a portion of an indicia space  683  within which dial  630  may be positioned. For example, base  670  may include at least one closure attachment feature (e.g., the shape of an exterior surface of side wall(s)  675  of base  670 ) and closure  620  may include at least one base attachment feature  624  (e.g., one or more grooves or female threads protruding from an interior surface of closure  620 ), where base  670  may snap into or otherwise fit base  670  within base attachment feature  624  for securing base  670  within closure space  623 , which may thereby define a reduced indicia space  683  between closure  620  and base  670 . Base attachment feature  624  may be positioned above bottle attachment feature  628  within closure space  623  of closure  620  such that base  670  may be coupled to closure  620  while still enabling bottle attachment feature  628  to removably couple closure  620  to bottle  690 . While closure space  623  may be defined by the interior surface(s) of side wall(s)  625 , top end  621 , and bottom end  629  of closure  620 , indicia space  683  may be defined by the interior surface(s) of side wall(s)  625  and top end  621  of closure  620  as well as by base  670 , such that indicia space  683  may be a portion of closure space  623 . Thus, base  670  may be configured to fit at least partially within closure space  623 , such that base  670  may define at least a portion of the bottom of indicia space  683 . Base  670  may be made of any suitable material or combination of materials and may be of any suitable dimensions. Dial  630  may be at least partially positioned within indicia space  683  when base  670  is coupled to closure  620 . Base  670  may have less material than base  270  or base  370 , and a thickness of base  670  (e.g., along the Z-axis) may be substantially constant while portions of base  670  may run adjacently along bottom  639  of dial  630  (e.g., to support dial  630 ). 
     Gear assembly  640  of cap  610  may be at least partially positioned within indicia space  683  along with dial  630 , and gear assembly  640  may be configured to selectively move dial  630  within indicia space  683  with respect to closure  620  for selectively aligning different dial indicia  636  with a closure indicia passageway  626  of closure  620 . Gear assembly  640  may include one or more gears that may be configured to translate a user motion that may be applied to a first portion of gear assembly  640  into movement of dial  630  with indicia space  683  (e.g., rotation of dial  630  about an axis A along a Z-axis). As shown, gear assembly  640  may include an upper or dial gear subassembly  650  and a lower or user gear subassembly  660 . Dial gear subassembly  650  may include an upper or dial cogwheel or gear  652  and, in some embodiments, an upper or dial gear shaft  658  that may extend away from gear  652  along an axis of rotation of gear  652  (e.g., axis A along a Z-axis). User gear subassembly  660  may include a lower or user cogwheel or gear  662  and, in some embodiments, a lower or user gear shaft  668  that may extend away from gear  662  along an axis of rotation of gear  662  (e.g., axis B along a Z-axis that may be parallel to axis A). User gear subassembly  660  may also include a user handle  666  that may be coupled to a portion of gear  662  (e.g., at an end of gear shaft  668 ), such that a user may apply a user force or motion to handle  666  for rotating gear  662 . Gear assembly  640  may be configured such that rotation of gear  662  may be configured to rotate or otherwise translate gear  652 , which may be configured to rotate or otherwise translate dial  630  with respect to closure  620  within indicia space  683 . For example, as shown, gear  662  may include teeth or cogs or any other suitable mechanical feature that may mesh with teeth or cogs or any other suitable mechanical feature of gear  652  to transmit torque therebetween within gear assembly  640  (e.g., as a transmission or gearbox). 
     Base  670  may be configured to support at least a portion of gear assembly  640  and/or dial  630  within indicia space  683  when base  670  is coupled to closure  620 . For example, as shown, at least a portion of user gear subassembly  660  (e.g., a bottom portion of gear  662 ) may be configured to rest against base  670  (e.g., against an exterior surface of top wall  671  of base  670 ). A user gear shaft opening  677  may be provided through base  670  (e.g., between top wall  671  and bottom wall  679 ) for enabling at least a portion of user gear shaft  668  and/or user handle  666  to extend therethrough from indicia space  683  to at least a portion of closure space  623  and/or bottle space  693  or for at least enabling a portion of gear subassembly  660  to be accessible therethrough, such that a portion of gear assembly  640  may be accessible to a user when cap  610  is not coupled to bottle  690  (e.g., when a user unscrews cap  610  from bottle  690  for accessing contents  697 ). Such accessibility to a portion of gear subassembly  660  by a user external to indicia space  683  (e.g., via user gear shaft opening  677  of base  670 ) may enable a user of assembly  600  to apply a user force or motion to handle  666  for rotating gear  662 . Alternatively or additionally, in some embodiments, user gear shaft opening  677  of base  670  may at least partially define an axis of rotation of user gear  662  and/or may otherwise limit at least a portion of a path along which at least a portion of user gear subassembly  660  may travel (e.g., by preventing or limiting movement of gear subassembly  660  along the X-axis and/or along the Y-axis within indicia space  683 ). For example, as shown, user gear  662  may be configured to rotate about an axis B, and gear shaft  668  may extend away from gear  662  along axis B, such that gear shaft opening  677  may align with axis B. Additionally or alternatively, as shown, at least a portion of dial gear subassembly  650  (e.g., a top portion of gear  652 ) may be coupled to dial  630  (e.g., to bottom wall  639  of dial  630 ), such that movement of gear subassembly  650  may provide movement of dial  630  (e.g., rotational movement about axis A). In some embodiments, a dial gear shaft opening  673  may be provided through at least a portion of base  670  (e.g., through top wall  671 ), where opening  673  may at least partially define an axis of rotation of dial gear  652  and/or may otherwise limit at least a portion of a path along which at least a portion of dial gear subassembly  650  may travel (e.g., by preventing or limiting movement of gear subassembly  650  along the X-axis and/or along the Y-axis within indicia space  683 ). For example, as shown, dial gear  652  may be configured to rotate about an axis A, and gear shaft  658  may extend away from gear  652  along axis A, such that gear shaft opening  673  may align with axis A. However, in some embodiments, gear shaft opening  673  and/or gear shaft  658  may not be necessary and other features of assembly  600  may define axis A about which gear  652  may rotate. For example, the positioning of base  670 , gear subassembly  660 , and dial  630  within indicia space  683  may limit the manner in which gear subassembly  650  may move within indicia space  683  (e.g., only to movement about axis A). In some embodiments, as shown in  FIG. 12 , an interior surface of top end  621  of closure  620  may include a dial movement feature  627  and an exterior surface of top end  631  of dial  630  may include a closure movement feature  637 , where such features  627  and  637  may interact with one another to at least partially define an axis of rotation of dial  630  with respect to closure  620  (e.g., axis A) or otherwise aid or limit such movement (e.g., by preventing or limiting movement of dial  630  along the X-axis and/or along the Y-axis within indicia space  683 ), for example, where feature  637  may be a nub that may extend into a cut out or notch  627 . In some embodiments, the thickness of the wall of top end  631  of dial  630  along the Z-axis combined with the thickness of gear assembly  640  along the Z-axis may be substantially equal to or slightly less than a thickness of indicia space  683  along the Z-axis, such that dial  630  and/or gear assembly  640  may be prevented or limited with respect to movement along the Z-axis. In some embodiments, dial indicia  636  may be replaceable on dial  630  (e.g., on top  631 ) when top  621  of closure  620  provides access to dial  630 . As shown in  FIGS. 11 and 12 , such dial indicia  636  may include a feature  636 C that may surround or otherwise interact with feature  637  of dial  630  (e.g., along axis A), while such dial indicia  636  may also include at least one feature  636 D that may surround or otherwise interact with feature  637 D of dial  630  (e.g., offset from axis A), which may enable proper orientation of indicia  636  with dial  630  when be positioned thereon by a user. 
     As just one example of use, a user may interact with handle  666  of user gear subassembly  660 , as may be accessible to a user through opening  677  of base  670 , for rotating gear shaft  668  and/or gear  662  in the direction of arrow R 2  about axis B, which may in turn rotate gear  652  of dial subassembly  650  in the direction of arrow R 1  about axis A, which may in turn rotate dial  630  in the direction of arrow R 1  about axis A. Such rotation of dial  630  in the direction of arrow R 1  about axis A within indicia space  683  with respect to closure  620  may alter the particular portion of dial  630  and, thus, the particular portion of dial indicia  636  that may be aligned with a particular closure indicia passageway  626 , which may alter what information may be provided to a user of assembly  600  by that particular portion of dial indicia  636 . For example, as shown in  FIG. 12 , when dial  630  is at a first particular orientation with respect to closure  620  and base  670  within indicia space  683 , a first indication of top dial indicia  636   t  may be aligned with and visible through indicia passageway  626   t . However, when dial  630  is rotated in the direction of arrow R 1  about axis A within indicia space  683  with respect to closure  620  from such a first orientation to a second orientation, the particular portion of dial  630  and, thus, the particular portion of dial indicia  636  that may be aligned with such indicia passageway  626  may be altered. As shown, handle  666  may include a flexible arm that may be configured to bend or flex in any suitable direction and/or to any suitable shape (e.g., with respect to the Z-axis) such that handle  666  may extend up towards or at least parallel to base  670  (e.g., as shown in  FIG. 10 ) and then may be bent to a second elongated state (e.g., with respect to the Z-axis), which may enable handle  666  to extend away from base  670  for easier use by a user and then bend towards or along base  670  so as not to extend (too far) out away from base  670  and/or indicia space  683  so as to interfere with content  697  of bottle  690  or a factory protective seal that may be initially provided by bottle  690  (e.g., across top  691 ). 
     While cap subassembly  610  may be configured to enable rotation of dial  630  in the direction of arrow R 1  about axis A within indicia space  683  with respect to closure  620  from a first orientation to a second orientation (e.g., to keep track of a medication schedule for content of bottle  690 ) by enabling user rotation of handle  666  in the direction of arrow R 2  about axis B, cap subassembly  610  may be configured to prevent rotation of dial  630  in the opposite direction of arrow R 2  about axis A. For example, as shown, gear assembly  640  may include a ratchet component  642  and base  670  may include a stopper component  672  that may be configured to interact with ratchet component  642  for preventing rotation of gear subassembly  650  in the direction of arrow R 2  while enabling rotation of gear subassembly  650  in the direction of arrow R 1 . For example, as shown, ratchet component  642  may be provided along a portion of gear subassembly  650  (e.g., adjacent a top portion of gear  652 ) and base  670  may provide stopper component  672  just adjacent ratchet component  642  in the +X direction (e.g., as an extension of a portion of top surface  671  of the base body of base  670 ), such that a free end of stopper component  672  may enable rotation of ratchet component  642  and, thus, gear  650  and dial  630  in the direction of arrow R 1  about axis A and at the same time prevent rotation of ratchet component  642  and, thus, gear  652  and dial  630  in the direction of arrow R 2  about axis A (e.g., due to the geometrical relationship between teeth or other suitable features of ratchet component  642  and the free end of stopper component  672 ). Moreover, interaction of ratchet component  642  and stopper component  672  may provide a user with an audible and/or tactile feedback to user adjustment of the indicia of assembly  600 . In some embodiments, stopper component  672  may be tensioned by a suitable amount such that the free end of stopper component  672  may exert a suitable force on ratchet component  642  for even preventing rotation of dial  630  in the direction of arrow R 1  about axis A, where such a force may be overcome by an intentional user force on handle  666  but that may not be overcome by any unintentional forces to which cap subassembly  610  may be susceptible during normal use of assembly  600 , such that components  642 / 672  may enable proper rotation of dial  630  in the direction of arrow R 1  but only if at least a certain amount of threshold force is applied to gear assembly  640  (e.g., to handle  666 ). 
     Additionally or alternatively to being provided with ratchet component and stopper component (e.g., ratchet component  642  and stopper component  672 ), gear assembly  640  may be configured to have a resting state in which movement of gear subassembly  650  may not translate into motion of gear subassembly  660  (and vice versa) and an active state in which movement of gear subassembly  650  may translate into motion of gear subassembly  660  (and vice versa). For example, as shown in  FIG. 12 , gear assembly  640  may be in a resting state, whereby a spacing distance (e.g., similar to spacing distance  141 ) may exist between gear  652  and gear  662  (e.g., along the X-axis and/or along the Z-axis of  FIG. 12 ), such that any rotation of user gear  662  in such a resting state (e.g., about axis B in the direction of arrow R 1  or arrow R 2 ) would not be translated into a rotation of dial gear  652 . In order to reconfigure gear assembly  640  from such a resting state into an active state, a user may first apply an upward force (e.g., in the +Z direction along axis B) on gear subassembly  660  (e.g., via handle  666 ), such that gear  662  may be moved upwards by the spacing distance in order to contact gear  652  (e.g., such that teeth of gear  662  may mesh with teeth of gear  652 ), and then the user may apply a rotation force (e.g., in the direction of arrow R 2  about axis B) to user gear subassembly  660  (e.g., via handle  666 ) for rotating meshed dial gear  652  in the direction of arrow R 1  about axis A. This may help prevent unintentional rotation of dial  630  and, thus, unintentional updating of exposed dial indicia  636 . 
     By reducing the thickness of dial  630  while also minimizing the thickness of indicia spacing  683  to only that which may be needed for gear assembly  630 , a height of indicia space  683  between top  621  and bottom  679  of assembly  600  may be shorter than a height of indicia space  183  between top  121  and bottom  179  of assembly  100 , while a portion of that reduced height may be used to store a portion of a handle  666  (e.g., a free end of handle  666 ) when in a non-use state. Additionally or alternatively, by enabling user access to dial  630  (e.g., via a movable top end  621  of closure  620 , a user may interchange dials  630  or indicia  636  thereon for using assembly  600  for different purposes with different appropriate adjustable indicia. 
     FIG.  13  and FIG.  14  (Assembly  700 ) 
       FIGS. 13 and 14  show another illustrative bottle container assembly  700 , which may be similar to assembly  100  of  FIGS. 1-6  but may include axially aligned gear subassemblies. Assembly  700  of  FIGS. 13 and 14  may include similar components to assembly  100  of  FIGS. 1-6 , with components of assembly  700  of  FIGS. 13 and 14  being labeled with “7xx” reference labels that may correspond to the “1xx” reference labels of the labeled components of assembly  100  of  FIGS. 1-6 , where differences therebetween may be described below. As shown, assembly  700  may include a bottle  790  and a cap  710  that may be coupled to bottle  790  for forming a closed container that may safely hold content therein. For example, bottle  790  may include a bottle body that may include one or more side walls  795  that may extend from a closed bottom end  799  to an at least partially open top end  791  for defining an interior bottle space  793 . Bottle  790  may be configured such that a user may insert content  797  through open end  791  into bottle space  793  (e.g., along the −Z direction) and/or may remove content  797  from bottle space  793  through open end  791  (e.g., along the +Z direction). Bottle  790  may be any suitable container portion that may be configured to hold any suitable content  797  in any suitable way. Bottle  790  may be made of any suitable material or combination of materials and may be of any suitable dimensions. 
     Cap  710  may be configured to be removably coupled to bottle  790 , such that cap  710  may cover open end  791  for preventing a user from accessing bottle space  793  when cap  710  is coupled to bottle  790 , and such that cap  710  may not cover at least a portion of open end  791  for enabling a user to access bottle space  793  when cap  710  is not coupled to bottle  790 . Assembly  700  may be configured in any suitable way for enabling cap subassembly to be removably coupled to bottle  790 . As just one example, bottle  790  may include at least one cap attachment feature  792  and cap  710  may include at least one bottle attachment feature  728 , where cap attachment feature  792  and bottle attachment feature  728  may be any suitable combination of reciprocal or otherwise related features that may be configured to interact with each other for removably coupling cap  710  to bottle  790  (e.g., threads, snaps, notches, clips, location or transition fits, etc.). Bottle  790  may also include a lip  794 , which may protrude from an exterior surface of body  795  below cap attachment feature  792 , where lip  794  may be configured to suspend cap subassembly  710  by at least a certain distance above the closed end. Cap attachment feature  792  and/or lip  794  may ensure a specific relationship between cap  710  and bottle  790  when cap  710  is coupled to bottle  790 . 
     Cap  710  may include a closure  720 , a dial  730 , a gear assembly  740 , and a base  770 . Closure  720  of cap  710  may include a closure body that may include one or more side walls  725  that may extend from an at least partially closed top end  721  to an at least partially open bottom end  729  for defining an interior closure space  723 . Closure  720  may also include one or more closure indicia passageways  726  through any suitable portions of closure  720  for selectively exposing to a user one or more other portions of cap subassembly  700  (e.g., portions of dial  730 , as described below). As shown, closure indicia passageways  726  may include at least one top closure indicia passageway  726   t  that may be provided through the wall of top end  721  of closure  720 . As described below, each closure indicia passageway  726  may be a hollow opening through a wall or other portion of closure  720  or may be such an opening that may be covered by or otherwise configured to include a transparent or translucent material or any other suitable object (e.g., a magnifying glass  726   tm ) that may enable communication of information therethrough to a user of assembly  700 . Closure  720  may be made of any suitable material or combination of materials and may be of any suitable dimensions. 
     Dial  730  of cap  710  may include a dial body that may include one or more side walls that may extend from an at least partially closed top end  731  to an at least partially closed bottom end  739 . Unlike dial  230 , which may be an at least partially open shape and/or include a side dial indicia, dial  730  may be a relatively thin closed dial (e.g., along the Z-axis) with no side dial indicia, which may reduce the thickness of cap  710 . Dial  730  may include any suitable dial indicia  736  that may be positioned on any suitable portions of dial  730  for selective display to a user of assembly  700 . As shown, dial indicia  736  may include top dial indicia  736   t  that may be provided on an exterior surface of top end  731  of dial  730 , and/or bottom dial indicia  736   b  that may be provided on an exterior surface of bottom end  739 . Dial  730  may be configured to fit at least partially within closure space  723 , such that dial  730  may be moved within closure space  723  with respect to closure  720  for selectively aligning different dial indicia  736  of dial  730  with a closure indicia passageway  726  of closure  720  and/or a base indicia passageway  776  of base  770 . Dial  730  may be made of any suitable material or combination of materials and may be of any suitable dimensions. Unlike dial  130 , dial  730  may be configured to be coupled (e.g., permanently or removably) to closure  720 , such that, for example, closure  720  may prevent dial  730  from moving (e.g., along the Z-axis). For example, dial  730  may include at least one closure attachment feature (e.g., the shape of an exterior surface of side wall(s)  735  of dial  730 ) and closure  720  may include at least one dial attachment feature  722  (e.g., one or more grooves or female threads protruding from an interior surface of closure  720 ), where dial  730  may snap into or otherwise fit dial  730  within dial attachment feature  722  for securing dial  730  within closure space  723 . Dial attachment feature  722  may be positioned above both base attachment feature  724  (described below) and bottle attachment feature  728  within closure space  723  of closure  720  such that dial  730  and base  770  may be coupled to closure  720  while still enabling bottle attachment feature  728  to removably couple closure  720  to bottle  790 . 
     Base  770  of cap  710  may include a base body that may include one or more side walls  775  that may extend from an at least partially closed top end  771  to an at least partially closed bottom end  779 . Base  770  may be configured to be coupled (e.g., permanently or removably) to closure  720 , such that, for example, base  770  and closure  720  may together define at least a portion of an indicia space  783  within which dial  730  may be positioned. For example, base  770  may include at least one closure attachment feature (e.g., the shape of an exterior surface of side wall(s)  775  of base  770 ) and closure  720  may include at least one base attachment feature  724  (e.g., one or more grooves or female threads protruding from an interior surface of closure  720 ), where base  770  may snap into or otherwise fit base  770  within base attachment feature  724  for securing base  770  within closure space  723 , which may thereby define a reduced indicia space  783  between closure  720  and base  770 . Base attachment feature  724  may be positioned above bottle attachment feature  728  within closure space  723  of closure  720  such that base  770  may be coupled to closure  720  while still enabling bottle attachment feature  728  to removably couple closure  720  to bottle  790 . While closure space  723  may be defined by the interior surface(s) of side wall(s)  725 , top end  721 , and bottom end  729  of closure  720 , indicia space  783  may be defined by the interior surface(s) of side wall(s)  725  and top end  721  of closure  720  as well as by base  770 , such that indicia space  783  may be a portion of closure space  723 . Thus, base  770  may be configured to fit at least partially within closure space  723 , such that base  770  may define at least a portion of the bottom of indicia space  783 . Base  770  may be made of any suitable material or combination of materials and may be of any suitable dimensions. Dial  730  may be at least partially positioned within indicia space  783  when base  770  is coupled to closure  720 . Base  770  may have less material than base  270  or base  370 , and a thickness of base  770  (e.g., along the Z-axis) may be substantially constant while portions of base  770  may run adjacently along bottom  739  of dial  730  (e.g., to support dial  730 ). 
     Gear assembly  740  of cap  710  may be at least partially positioned within indicia space  783  along with dial  730 , and gear assembly  740  may be configured to selectively move dial  730  within indicia space  783  with respect to closure  720  for selectively aligning different dial indicia  736  with a closure indicia passageway  726  of closure  720 . Gear assembly  740  may include one or more gears that may be configured to translate a user motion that may be applied to a first portion of gear assembly  740  into movement of dial  730  with indicia space  783  (e.g., rotation of dial  730  about an axis A along a Z-axis). As shown, gear assembly  740  may include an upper or dial gear subassembly  750  and a lower or user gear subassembly  760 . Dial gear subassembly  750  may include an upper or dial cogwheel or gear  752  and, in some embodiments, an upper or dial gear shaft (not shown) that may extend away from gear  752  along an axis of rotation of gear  752  (e.g., axis A along a Z-axis). User gear subassembly  760  may include a lower or user cogwheel or gear  762  and, in some embodiments, a lower or user gear shaft  768  that may extend away from gear  762  along an axis of rotation of gear  762  (e.g., axis A). User gear subassembly  760  may also include a user handle  766  that may be coupled to a portion of gear  762  (e.g., at an end of gear shaft  768 ), such that a user may apply a user force or motion to handle  766  for rotating gear  762 . Gear assembly  740  may be configured such that rotation of gear  762  may be configured to rotate or otherwise translate gear  752 , which may be configured to rotate or otherwise translate dial  730  with respect to closure  720  within indicia space  783 . For example, as shown, gear  762  may include teeth or cogs or any other suitable mechanical feature of gear  762  (e.g., on a cylindrical or conical or any other suitable shaped exterior surface of gear  762 , such that teeth of gear  762  may extend away from axis A of gear  762  towards gear  752  (e.g., along the X-axis)) that may mesh with teeth or cogs or any other suitable mechanical feature of gear  752  (e.g., on a cylindrical or conical or any other suitable shaped interior surface of gear  752 , such that teeth of gear  752  may extend away towards axis A of gear  752  and towards gear  762  (e.g., along the X-axis)) to transmit torque therebetween within gear assembly  740  (e.g., as a transmission or gearbox). Gear  752  may be cup shaped for receiving at least a portion of gear  762  therein (e.g., in a nesting fashion). 
     Base  770  may be configured to support at least a portion of gear assembly  740  and/or dial  730  within indicia space  783  when base  770  is coupled to closure  720 . For example, as shown, at least a portion of user gear subassembly  760  (e.g., a bottom portion of gear  762 ) may be configured to rest against base  770  (e.g., against an exterior surface of top wall  771  of base  770 ). A user gear shaft opening  777  may be provided through base  770  (e.g., between top wall  771  and bottom wall  779 ) for enabling at least a portion of user gear shaft  768  and/or user handle  766  to extend therethrough from indicia space  783  to at least a portion of closure space  723  and/or bottle space  793  or for at least enabling a portion of gear subassembly  760  to be accessible therethrough, such that a portion of gear assembly  740  may be accessible to a user when cap  710  is not coupled to bottle  790  (e.g., when a user unscrews cap  710  from bottle  790  for accessing contents  797 ). Such accessibility to a portion of gear subassembly  760  by a user external to indicia space  783  (e.g., via user gear shaft opening  777  of base  770 ) may enable a user of assembly  700  to apply a user force or motion to handle  766  for rotating gear  762 . Alternatively or additionally, in some embodiments, user gear shaft opening  777  of base  770  may at least partially define an axis of rotation of user gear  762  and/or may otherwise limit at least a portion of a path along which at least a portion of user gear subassembly  760  may travel (e.g., by preventing or limiting movement of gear subassembly  760  along the X-axis and/or along the Y-axis within indicia space  783 ). For example, as shown, user gear  762  may be configured to rotate about an axis A, and gear shaft  768  may extend away from gear  762  along axis A, such that gear shaft opening  777  may align with axis A. Additionally or alternatively, as shown, at least a portion of dial gear subassembly  750  (e.g., a top portion of gear  752 ) may be coupled to dial  730  (e.g., to bottom wall  739  of dial  730 ), such that movement of gear subassembly  750  may provide movement of dial  730  (e.g., rotational movement about axis A). In some embodiments, the positioning of base  770 , gear subassembly  760 , and dial  730  within indicia space  783  may limit the manner in which gear subassembly  750  may move within indicia space  783  (e.g., only to movement about axis A). In some embodiments, as shown in  FIG. 14 , an interior surface of top end  721  of closure  720  may include a dial movement feature  727  and an exterior surface of top end  731  of dial  730  may include a closure movement feature  737 , where such features  727  and  737  may interact with one another to at least partially define an axis of rotation of dial  730  with respect to closure  720  (e.g., axis A) or otherwise aid or limit such movement (e.g., by preventing or limiting movement of dial  730  along the X-axis and/or along the Y-axis within indicia space  783 ), for example, where feature  737  may be a nub that may extend into a cut out or notch  727 . In some embodiments, the thickness of the wall of top end  731  of dial  730  along the Z-axis combined with the thickness of gear assembly  740  along the Z-axis may be substantially equal to or slightly less than a thickness of indicia space  783  along the Z-axis, such that dial  730  and/or gear assembly  740  may be prevented or limited with respect to movement along the Z-axis. 
     As just one example of use, a user may interact with handle  766  of user gear subassembly  760 , as may be accessible to a user through opening  777  of base  770 , for rotating gear shaft  768  and/or gear  762  in the direction of arrow R 1  about axis A, which may in turn rotate gear  752  of dial subassembly  750  in the direction of arrow R 1  about axis A, which may in turn rotate dial  730  in the direction of arrow R 1  about axis A. Such rotation of dial  730  in the direction of arrow R 1  about axis A within indicia space  783  with respect to closure  720  may alter the particular portion of dial  730  and, thus, the particular portion of dial indicia  736  that may be aligned with a particular closure indicia passageway  726 , which may alter what information may be provided to a user of assembly  700  by that particular portion of dial indicia  736 . For example, as shown in  FIG. 14 , when dial  730  is at a first particular orientation with respect to closure  720  and base  770  within indicia space  783 , a first indication of top dial indicia  736   t  may be aligned with and visible through indicia passageway  726   t  and a first indication of bottom dial indicia  736   b  may be aligned with and visible through indicia passageway  776  (e.g.,  776   m ). However, when dial  730  is rotated in the direction of arrow R 1  about axis A within indicia space  783  with respect to closure  720  from such a first orientation to a second orientation, the particular portion of dial  730  and, thus, the particular portion of dial indicia  736  that may be aligned with such indicia passageway  726 / 776  may be altered. As shown, handle  766  may not extend beyond base  770  (e.g., in the −Z direction), but instead may include a friction pad or other suitable feature at its end within opening  777  such that a user may grip handle  766  (e.g., with the tip of a user finger), while handle  766  does not take up any real estate of assembly  700  outside of indicia space  783 , which may prevent handle  766  from interfering with content  797  of bottle  790  or a factory protective seal that may be initially provided by bottle  790  (e.g., across top  791 ). 
     While cap subassembly  710  may be configured to enable rotation of dial  730  in the direction of arrow R 1  about axis A within indicia space  783  with respect to closure  720  from a first orientation to a second orientation (e.g., to keep track of a medication schedule for content of bottle  790 ) by enabling user rotation of handle  766  in the direction of arrow R 1  about axis A, cap subassembly  710  may be configured to prevent rotation of dial  730  in the opposite direction of arrow R 2  about axis A. For example, as shown, gear assembly  740  may include a ratchet component  742  and base  770  may include a stopper component  772  that may be configured to interact with ratchet component  742  for preventing rotation of gear subassembly  750  in the direction of arrow R 2  while enabling rotation of gear subassembly  750  in the direction of arrow R 1 . For example, as shown, ratchet component  742  may be provided along a portion of gear subassembly  750  (e.g., adjacent a top portion of gear  752 ) and base  770  may provide stopper component  772  just adjacent ratchet component  742  in the +X direction (e.g., as an extension of a portion of top surface  771  of the base body of base  770 ), such that a free end of stopper component  772  may enable rotation of ratchet component  742  and, thus, gear  750  and dial  730  in the direction of arrow R 1  about axis A and at the same time prevent rotation of ratchet component  742  and, thus, gear  752  and dial  730  in the direction of arrow R 2  about axis A (e.g., due to the geometrical relationship between teeth or other suitable features of ratchet component  742  and the free end of stopper component  772 ). Moreover, interaction of ratchet component  742  and stopper component  772  may provide a user with an audible and/or tactile feedback to user adjustment of the indicia of assembly  700 . In some embodiments, stopper component  772  may be tensioned by a suitable amount such that the free end of stopper component  772  may exert a suitable force on ratchet component  742  for even preventing rotation of dial  730  in the direction of arrow R 1  about axis A, where such a force may be overcome by an intentional user force on handle  766  but that may not be overcome by any unintentional forces to which cap subassembly  710  may be susceptible during normal use of assembly  700 , such that components  742 / 772  may enable proper rotation of dial  730  in the direction of arrow R 1  but only if at least a certain amount of threshold force is applied to gear assembly  740  (e.g., to handle  766 ). 
     Additionally or alternatively to being provided with ratchet component and stopper component (e.g., ratchet component  742  and stopper component  772 ), gear assembly  740  may be configured to have a resting state in which movement of gear subassembly  750  may not translate into motion of gear subassembly  760  (and vice versa) and an active state in which movement of gear subassembly  750  may translate into motion of gear subassembly  760  (and vice versa). For example, as shown in  FIG. 14 , gear assembly  740  may be in a resting state, whereby a spacing distance (e.g., similar to spacing distance  141 ) may exist between gear  752  and gear  762  (e.g., along the X-axis and/or along the Z-axis of  FIG. 14 ), such that any rotation of user gear  762  in such a resting state (e.g., about axis A in the direction of arrow R 1  or arrow R 2 ) would not be translated into a rotation of dial gear  752 . In order to reconfigure gear assembly  740  from such a resting state into an active state, a user may first apply an upward force (e.g., in the +Z direction along axis A) on gear subassembly  760  (e.g., via handle  766 ), such that gear  762  may be moved upwards by the spacing distance in order to contact gear  752  (e.g., such that teeth of gear  762  may mesh with teeth of gear  752 ), and then the user may apply a rotation force (e.g., in the direction of arrow R 1  about axis A) to user gear subassembly  760  (e.g., via handle  766 ) for rotating meshed dial gear  752  in the direction of arrow R 1  about axis A. This may help prevent unintentional rotation of dial  730  and, thus, unintentional updating of exposed dial indicia  736 . 
     By reducing the thickness of dial  730  while also minimizing the thickness of indicia spacing  783  to only that which may be needed for gear assembly  730 , a height of indicia space  783  between top  721  and bottom  779  of assembly  700  may be shorter than a height of indicia space  183  between top  121  and bottom  179  of assembly  100 . Additionally or alternatively, by nesting a user gear subassembly  760  within a dial gear subassembly  750  (or vice versa), such as within an X-Y plane, may reduce a width of at least a portion of an indicia space  783  (e.g., along the X-axis and/or along the Y-axis). 
     FIGS.  15 - 21  (Assembly  800 ) 
       FIGS. 15-21  show another illustrative bottle container assembly  800 , which may be similar to assembly  100  of  FIGS. 1-6  but may include a cap with a push button that may be operative to move linearly along an axis for rotating a dial about the axis for changing the portion of indicia of the dial that may be aligned with a passageway for viewing by a user. Assembly  800  of  FIGS. 15-21  may include one or more similar components to assembly  100  of  FIGS. 1-6 , with components of assembly  800  of  FIGS. 15-21  being labeled with “8xx” reference labels that may correspond to the “1xx” reference labels of the labeled components of assembly  100  of  FIGS. 1-6 , where differences therebetween may be described below. As shown, assembly  800  may include a bottle  890  and a cap  810  that may be coupled to bottle  890  for forming a closed container that may safely hold content therein. For example, bottle  890  may include a bottle body that may include one or more side walls  895  that may extend from a closed bottom end  899  to an at least partially open top end  891  for defining an interior bottle space  893 . Bottle  890  may be configured such that a user may insert content  897  through open end  891  into bottle space  893  (e.g., along the −Z direction) and/or may remove content  897  from bottle space  893  through open end  891  (e.g., along the ±Z direction). Bottle  890  may be any suitable container portion that may be configured to hold any suitable content  897  in any suitable way. Bottle  890  may be made of any suitable material or combination of materials and may be of any suitable dimensions. 
     Cap  810  may be configured to be removably coupled to bottle  890 , such that cap  810  may cover open end  891  for preventing a user from accessing bottle space  893  when cap  810  is coupled to bottle  890 , and such that cap  810  may not cover at least a portion of open end  891  for enabling a user to access bottle space  893  when cap  810  is not coupled to bottle  890 . Assembly  800  may be configured in any suitable way for enabling cap subassembly  810  to be removably coupled to bottle  890 . As just one example, bottle  890  may include at least one cap attachment feature  892  and cap  810  may include at least one bottle attachment feature  828 , where cap attachment feature  892  and bottle attachment feature  828  may be any suitable combination of reciprocal or otherwise related features that may be configured to interact with each other for removably coupling cap  810  to bottle  890  (e.g., threads, snaps, notches, clips, location or transition fits, etc.). Bottle  890  may also include a lip  894 , which may protrude from an exterior surface of body  895  below cap attachment feature  892 , where lip  894  may be configured to suspend cap subassembly  810  by at least a certain distance above the closed end. Cap attachment feature  892  and/or lip  894  may ensure a specific relationship between cap  810  and bottle  890  when cap  810  is coupled to bottle  890 . 
     Cap  810  may include a closure  820 , a dial  830 , a push button  844 , and a biasing mechanism  881 . Closure  820  of cap  810  may include a closure body that may include one or more side walls  825  that may extend from an at least partially closed top end  821  to an at least partially open bottom end  829  for defining an interior closure space  823 . Closure  820  may also include one or more closure indicia passageways  826  through any suitable portions of closure  820  for selectively exposing to a user one or more other portions of cap subassembly  810  (e.g., portions of dial  830 , as described below). As shown, closure indicia passageways  826  may include at least one top closure indicia passageway  826   t  that may be provided through the wall of top end  821  of closure  820  and/or at least one side closure indicia passageway  826   s  that may be provided through at least one side wall  825  of closure  820 . Each closure indicia passageway  826  may be a hollow opening through a wall or other portion of closure  820  or may be such an opening that may be covered by or otherwise configured to include a transparent or translucent material or any other suitable object (e.g., a magnifying glass  826   tm  and/or  826   sm ) that may enable communication of information therethrough to a user of assembly  800 . Closure  820  may be made of any suitable material or combination of materials and may be of any suitable dimensions. 
     Dial  830  of cap  810  may include a dial body that may include one or more side walls  835  that may extend from an at least partially closed top end  831  to an at least partially open bottom end  839 . Dial  830  may define an interior dial space  833 , which may be accessible via a dial opening  838 , which may be provided through any suitable portion of the dial body, such as through bottom end  839 . At least one groove  832  may be provided along any suitable surface of dial  830 , such as along an interior surface  834  of one or more side walls  835 , where dial groove  832  may be accessible within dial space  833  (e.g., by a portion of push button  844 , as described below). Dial  830  may include any suitable dial indicia  836  that may be positioned on any suitable portions of dial  830  for selective display to a user of assembly  800 . As shown, dial indicia  836  may include top dial indicia  836   t  that may be provided on an exterior surface of top end  831  of dial  830 , and/or side dial indicia  836   s  that may be provided on an exterior surface of one or more side walls  835 . Dial  830  may be configured to fit at least partially within closure space  823 , such that dial  830  may be moved within closure space  823  with respect to closure  820  for selectively aligning different dial indicia  836  of dial  830  with a closure indicia passageway  826  of closure  820 . Dial  830  may be made of any suitable material or combination of materials and may be of any suitable dimensions. 
     Button  844  of cap  810  may include a button body that may include one or more side walls  845  that may extend from a top end  841  to a bottom end  849 . Button  844  may define an interior button space  843 , which may be accessible via a top button opening through a top surface at top end  841  and/or via a bottom button opening through a bottom surface at bottom end  849 . Button  844  may be configured to be coupled (e.g., permanently or removably) to closure  820  (e.g., at least partially within closure space  823 ), such that, for example, closure  820  may prevent button  844  from rotating (e.g., about an axis A along a Z-axis) while closure  820  may still enable button  844  to move linearly (e.g., along axis A). For example, button  844  may include at least one closure interaction feature  846  (e.g., a feature extending outwardly from an exterior surface of side wall(s)  845  of button  844 ) and closure  820  may include at least one button interaction feature  822   b  (e.g., one or more grooves within an interior surface of closure  820 ), where button  844  may snap into or otherwise fit each closure interaction feature  846  of button  844  within a button interaction feature  822   b  of closure  820  for securing button  844  at least partially within closure space  823 . Button  844  may be configured to be coupled (e.g., permanently or removably) to closure  820 , such that, for example, button  844  and closure  820  may together define at least a portion of an indicia space  883  within which dial  830  may be positioned. Each button interaction feature  822   b  may be positioned above bottle attachment feature  828  within closure space  823  of closure  820  such that button  844  may be coupled to closure  820  while still enabling bottle attachment feature  828  to removably couple closure  820  to bottle  890  (see, e.g.,  FIG. 18 ). While closure space  823  may be defined by the interior surface(s) of side wall(s)  825 , top end  821 , and bottom end  829  of closure  820 , indicia space  883  may be defined by upper portions of the interior surface(s) of side wall(s)  825  and top end  821  of closure  820  as well as by a portion of button  844  (e.g., bottom  849  and/or each closure interaction feature  846  of button  844 ), such that indicia space  883  may be a portion of closure space  823 . Thus, button  844  may be configured to fit at least partially within closure space  823 , such that button  844  may define at least a portion of the bottom of indicia space  883 . Button  844  may be made of any suitable material or combination of materials and may be of any suitable dimensions. Dial  830  may be at least partially positioned within indicia space  883  when button  844  is coupled to closure  820 . In some embodiments, as shown in  FIG. 17 , an interior surface of top end  821  of closure  820  may include any suitable dial movement feature  827  and an exterior surface of top end  831  of dial  830  may include any suitable closure movement feature  837 , where such features  827  and  837  may interact with one another to at least partially define an axis of rotation of dial  830  with respect to closure  820  (e.g., axis A) or otherwise aid or limit such movement (e.g., by preventing or limiting movement of dial  830  along the X-axis and/or along the Y-axis within indicia space  883 ), for example, where feature  837  may be a nub that may extend into a cut out or notch  827 . 
     Button  844  may also include one or more dial interaction features  847  that may be operative to interact with dial groove  832  of dial  830  for rotating dial  830  within indicia space  883  when button  844  is moved within closure space  823 . For example, as mentioned, the geometry of at least one button interaction feature  822   b  of closure  820  may interact with the geometry of at least one closure interaction feature  846  of button  844  to prevent rotation of button  844  within closure space  823  (e.g., within closure space  823  about axis A) while still enabling linear movement of button  844  within closure space  823  (e.g., within closure space  823  along axis A, such as, for example, between a first “low” position of  FIG. 17  and/or  FIG. 19  to a second “high” position of  FIG. 18 ). The interaction of at least one dial interaction feature  847  with at least one dial groove  832  may enable translation of such linear movement of button  844  within closure space  823  into rotational movement of dial  830  within indicia space  883  (e.g., about axis A), for example, such that different indicia  836  of dial  830  may be rotated into alignment with a passageway  826  of closure  820 . As shown, groove  832  may extend along interior surface  834  of dial  830  about at least a portion of axis A, and, when button  844  is coupled to closure  820 , at least a portion of each dial interaction feature  847  may extend into at least a portion of dial space  833  for interacting with groove  832 . Each dial interaction feature  847  may extend away from top end  841  of button  844  (e.g., in the +Z-direction) to a top end  847   t  of that dial interaction feature  847 . At some location along the length of dial interaction feature  847 , an extender portion  847   e  may extend from the main body of interaction feature  847  (e.g., away from axis A, such as in the −X-direction of  FIG. 17 ) for extending at least partially into groove  832 . In some embodiments, top end  847   t  of a dial interaction feature  847  may be a free end for enabling deflection of extender  847   e  towards and/or away from axis A, for example, such that extender  847   e  may be enabled to snap or otherwise fit into groove  832 . In some embodiments, extender  847   e  may extend away from the main body of interaction feature  847  at top end  847   t . In other embodiments, extender  847   e  may extend away from the main body of interaction feature  847  at some point below top end  847   t , for example, such that top end  847   t  may be operative to interact with an interior surface of top  831  of dial  830  (see, e.g.,  FIG. 19 ), which may at least partially limit the linear movement of button  844  in the +Z-direction. 
     Biasing mechanism  881  may be positioned at any suitable position within closure space  823  for biasing at least a portion of button  844  away from top end  821  of closure  820  (e.g., in the −Z-direction), for example, to at least partially control the linear movement of button  844  within closure space  823 . Biasing mechanism  881  may be any suitable component or combination of components made of any suitable material (e.g., metal and/or plastic and/or rubber), such as any suitable spring, that may be operative to be compressed or tensioned for enabling movement of at least a portion of button  844  towards top end  821  of closure  820  (e.g., in the +Z-direction) when a suitable amount of force is applied to button  844  in that direction by an object remote from cap subassembly  810  (e.g., a user U or bottle  890 ), while also being operative to decompress or relax for moving at least a portion of button  844  away from top end  821  (e.g., in the −Z-direction) when such a suitable amount of force is not applied to button  844  by such a remote object. As shown, for example, biasing mechanism  881  may include at least one spring that may be operative to be compressed from a first state (e.g., a first expanded or decompressed relaxed state of  FIG. 17  and/or  FIG. 19 , whereby biasing mechanism  881  may have a first length B 1  along the Z-axis when no external force is applied to button  844 ) to a second state (e.g., a compressed or tensioned state of  FIG. 18 , whereby biasing mechanism  881  may have a second length B 2  along the Z-axis that is shorter than length B 1 ) when a suitable external force is applied to button  844  in the +Z-direction (e.g., by user U or bottle  890 , as described below in more detail) and that may be operative to expand from the second state to the first state when no such suitable external force is applied to button  844 . As shown, biasing mechanism  881  may be positioned within indicia space  883  for extending between an interior surface of top  831  of dial  830  and an interior surface of bottom  849  of button  844  (e.g., along and/or about axis A). In other embodiments, biasing mechanism  881  may be positioned within closure space  823  for extending between an interior surface of top  821  of closure  820  (e.g., through an opening in top  831  of dial  830  (e.g., similarly to described below with respect to  FIG. 22 )) and any suitable surface of button  844  (e.g., along and/or about axis A). In some embodiments, rather than extending to an interior surface of bottom  849  of button  844 , biasing mechanism  881  may extend to any other suitable portion of button  844 , such as to a top portion of button  844  (e.g., top  841  or one or more top portions  847   t  (e.g., similarly to described below with respect to  FIG. 35 )). 
     Dial groove  832  may extend along at least a portion of the interior of dial  830  about at least a portion of axis A. Groove  832  may have any suitable shape for translating movement of button  844  (e.g., extender  847   e ) towards and/or away from top  821  of closure  820  (e.g., movement of button  844  along or substantially along the Z-axis) into rotation or other suitable movement of dial  830  about axis A. For example, as shown, groove  832  may include two or more vertical or substantially vertical segments  832   v  (e.g., extending along or substantially along a Z-axis) and at least two diagonal segments  832   d , where each diagonal segment  832   d  may couple an upper portion  832   u  of a first vertical segment  832   v  to a lower portion  832   l  of a second vertical segment  832   v  that may be adjacent the first vertical segment  832   v . Different stages of use of cap subassembly  810  may be shown in  FIGS. 17-19  and may illustrate how the geometry of groove  832  may at least partially dictate movement between such stages. It is to be understood that, rather than an extender  847   e  of button  844  moving along a path defined by groove  832  of dial  830 , any suitable feature of button  844  may interact with any suitable feature of dial  830  for enabling the below-described action. For example, feature  832  may be a track that extends outwardly from dial  830  for defining a path as opposed to a groove formed in a surface of dial  830  while feature  847   e  may be an arm that latches onto the track and that is operative to move along the track. In other embodiments, feature  847   e  may be a groove or a track or any other suitable path-defining element while feature  832  of dial  830  may be an extender or arm or any other suitable feature that may interact with the path-defining element. 
     As shown in  FIG. 17 , cap subassembly  810  may be in a first state, where no force external to cap subassembly  810  may be applied to any portion of cap subassembly  810 , such that such a first state of cap subassembly  810  may be referred to as a relaxed state or an expanded state (e.g., as biasing mechanism  881  may be in an expanded state of a first length B 1 , which may be limited from expanding to a greater length by one or more of a biasing characteristic or geometry of biasing mechanism  881 , the interaction of at least one closure interaction feature  846  of button  844  with the bottom of a respective button interaction feature  822   b  of closure  820 , and/or the interaction of at least one extender  847   e  of button  844  with a bottom of a respective vertical segment  832   v  of groove  832  of dial  830 ). In such a first state of  FIG. 17 , a first particular side indicia (e.g., “Fri”) of side indicia  836   s  may be aligned with side passageway  826   s  or a first particular top indicia of top indicia  836   t  may be aligned with top passageway  826   t , while each extender  847   e  of button  844  may be positioned within a respective vertical segment  832   v  of groove  832  of dial  830  (e.g., at or proximal to the lower portion  832   l  of that vertical segment). 
     Next, when any suitable external force is applied to cap subassembly  810  that may be large enough to at least overcome the biasing force of biasing mechanism  881  for reducing the vertical length B 1  of biasing mechanism  881 , at least a portion of button  844  may be moved in the +Z-direction. For example, in some embodiments, as shown in  FIG. 18 , a user U may apply a user force in the +Z-direction onto any accessible portion of button  844  that may provide an external force interface (e.g., an exterior surface of bottom  849 ) that may reduce the vertical length of biasing mechanism  881  to length B 2  (e.g., when cap  810  is not coupled to bottle  890 ). In alternative embodiments, as also shown in  FIG. 18 , when bottle  890  is coupled to closure  820 , a portion of bottle  890  (e.g., top  891 ) may be operative to apply a bottle force in the +Z-direction onto any suitable portion of button  844  that may provide an external force interface (e.g., an exterior surface of bottom  849 ) that may reduce the vertical length of biasing mechanism  881  to length B 2 . In any event, such an external force may provide a second state of cap subassembly  810  of  FIG. 18 . Such a second state of cap subassembly  810  may be referred to as a compressed state or tensioned state, as biasing mechanism  881  may be in a compressed or tensioned state of a second reduced length B 2 , which may be limited from compressing to an even shorter length by one or more of a biasing characteristic or geometry of biasing mechanism  881  (e.g., the equilibrium length of a spring), the interaction of at least one closure interaction feature  846  of button  844  with the top of a respective button interaction feature  822   b  of closure  820 , the interaction of at least one extender  847   e  of button  844  with a top of a respective vertical segment  832   v  of groove  832  of dial  830 , the interaction of top  847   t  of button  844  with a portion of dial  830  (e.g., an interior surface of top  831 ), and/or the interaction of bottle  890  with closure  820  (e.g., lip  894  with bottom end  829 ). In such a second state of  FIG. 18 , the first particular side indicia (e.g., “Fri”) of side indicia  836   s  may or may not remain aligned with side passageway  826   s . Moreover, in such a second state of  FIG. 18 , each extender  847   e  of button  844  may remain positioned within the same respective vertical segment  832   v  of groove  832  of dial  830  as it was at the first state of  FIG. 17 , but at a location within that vertical segment  832   v  that is at or proximal to the upper portion  832   u  of that vertical segment. 
     As shown in  FIG. 19 , cap subassembly  810  may advance to a third state when the external force being applied to cap subassembly  810  in its second state of  FIG. 18  is terminated or reduced a suitable amount. For example, when the external force applied by user U or bottle  890  is at least partially reduced or removed such that bias mechanism  881  forces each extender  847   e  of button  844  in a downward direction (e.g., in the −Z-direction), the geometry of groove  832  and its interaction with extender  847   e  may be operative to prevent extender  847   e  from traveling back down the same initial vertical segment  832   v  in which extender  847   e  was located in its second state of  FIG. 18  (e.g., in the −Z-direction) but rather may be operative to guide the travel of extender  847   e  diagonally downwardly (e.g., in the direction of arrow D of  FIGS. 17 and 18 ) along the diagonal segment  832   d  extending from the upper portion  832   u  of the initial vertical segment  832   v  of the first and second states and into the lower portion  832   l  of an adjacent new vertical segment  832   v  for the third state of cap subassembly  810 . Such diagonal movement of extender  847   e  with respect to dial  830  along groove  832  may rotate dial  830  about axis A from its rotational orientation of the second state of  FIG. 18  to its rotational orientation of the third state of  FIG. 19  (e.g., by an arc length equal to the arc length between the two adjacent vertical segments  832   v ). In such a third state of  FIG. 19 , a new particular side indicia (e.g., “Sat”) of side indicia  836   s  may now be aligned with side passageway  826   s  (e.g., as compared to “Fri” of the first state of  FIG. 17 ) or a new particular top indicia of top indicia  836   t  may be aligned with top passageway  826   t , as each extender  847   e  of button  844  may be positioned within a new respective vertical segment  832   v  of groove  832  of dial  830  (e.g., at or proximal to the lower portion  832   l  of that new vertical segment). Such a third state of cap subassembly  810  of  FIG. 19  may also be referred to as a relaxed state or an expanded state (e.g., as biasing mechanism  881  may be in an expanded state of first length B 1 , which may be limited from expanding to a greater length by one or more of a biasing characteristic or geometry of biasing mechanism  881 , the interaction of at least one closure interaction feature  846  of button  844  with the bottom of a respective button interaction feature  822   b  of closure  820 , and/or the interaction of at least one extender  847   e  of button  844  with a bottom of the new respective vertical segment  832   v  of groove  832  of dial  830 ). Therefore, by limiting the motion of each extender  847   e  of button  844  within dial space  833  to vertical or at least substantially vertical movement (e.g., along the Z-axis (e.g., due to interaction of features  822   b  and  846 )), the interaction between the geometry of downwardly moving extender  847   e  of button  844  and the geometry of groove  832  of dial  830  may rotate dial  830  about axis A for aligning new indicia with one or more passageways for viewing by a user of cap subassembly  810 . 
     Groove  832  of dial  830  may have any suitable geometry for enabling such rotation of dial  830  with respect to closure  820  in response to such linear movement of button  844  with respect to closure  820 . For example, in some embodiments, as shown in  FIG. 20 , portions of groove  832  provided with “|||” or “\\\” markings (e.g., the “deeper” portions  832   p  of groove  832 ) may extend a greater depth into the side wall(s)  835  of dial  830  than the portions of groove  832  provided with no markings (e.g., the “normal” portions  832   n  of groove  832 ), and/or the portions of groove  832  provided with no markings may extend a greater depth into the side wall(s)  835  of dial  830  than the portions of groove  832  provided with “+++” markings (e.g., the “shallower” portions  832   s  of groove  832 ). As mentioned, each extender  847   e  of button  844  may be operative to deflect inwardly and/or outwardly with respect to axis A when suitable force is applied thereto. In some embodiments, when cap subassembly  810  is assembled, each extender  847   e  of button  844  may snap into groove  832  and may be biased to extend to at least a depth beyond the depth of the normal portions of groove  832  when no external force is applied to each extender  847   e , such that each extender  847   e  may extend into the deeper portions of groove  832  when aligned with such a deeper portion, and such that each extender  847   e  may deflect inwardly towards axis A when aligned with a shallower portion of groove  832 . Such variance in the depth of groove  832  may be of any suitable amount and may enable a better user experience and/or may ensure a desired interaction between each extender  847   e  of button  844  and groove  832 . For example, in some embodiments, as shown in  FIG. 20 , deeper portions of groove  832  may be provided at upper portion  832   u  and/or lower portion  832   l  of one or more vertical segments  832   v  and/or at an upper portion  832   t  of one or more diagonal segments  832   d , normal portions of groove  832  may be provided along the middle of one or more vertical segments  832   v  and/or along the middle of one or more diagonal segments  832   d , and/or shallower portions of groove  832  may be provided at a portion of one or more vertical segments  832   v  just below an adjoining diagonal segment  832   d  and/or at a lower portion  832   b  of one or more diagonal segments  832   d  just prior to an adjoining vertical segment  832   v . For example, a shallower portion of a vertical segment  832   v  just below an upper portion  832   t  of an adjoining diagonal segment  832   d  may not only require a certain amount of force to be applied to button  844  (e.g., by user U or bottle  90 ) to enable extender  847   e  to move upwardly (e.g., in the ±Z-direction) within a vertical segment  832   v  from a normal portion and beyond that shallower portion and into an upper portion  832   u  of that vertical segment and thus into an upper portion  832   t  of an adjoining diagonal segment  832   d  (e.g., to require intentional force and/or to provide an audible click or tactile sensation when a rotation of dial  830  is imminent) but also may require a certain amount of force to be applied to button  844  (e.g., by bias mechanism  881 ) to enable extender  847   e  to move downwardly (e.g., in the −Z-direction) within the vertical segment  832   v  from a deep upper portion  832   u  and beyond that shallower portion and into a normal middle portion of that same vertical segment thereby preventing a desired rotation of dial  830  (e.g., bias mechanism  881  may be configured to not enable such a force, thereby ensuring that desired rotation of dial  830  is not prevented by such movement of extender  847   e  downwardly beyond such a shallower portion of a vertical segment  832   v  just below an adjoining diagonal segment  832   d ). As another example, as shown by groove  832  of  FIG. 20  but not by an alternative groove  832 ′ of  FIG. 21 , a shallower portion at a lower portion  832   b  of one or more diagonal segments  832   d  just prior to a lower portion  832   l  of an adjoining vertical segment  832   v  may not only require a certain amount of force to be applied to button  844  (e.g., downward force by biasing mechanism  881 ) to enable extender  847   e  to move diagonally downwardly within a diagonal segment  832   d  from a normal portion and beyond that shallower portion and into a lower portion  832   l  of an adjoining vertical segment  832   v  (e.g., bias mechanism  881  may be configured to provide such a force, thereby ensuring that desired rotation of dial  830  is not prevented and/or to provide an audible click or tactile sensation when a rotation of dial  830  is completed) but also may require a certain amount of force to be applied to button  844  to enable extender  847   e  to move diagonally upwardly back up along that diagonal segment  832   d  from a deep lower portion  832   l  and beyond that shallower portion and into a normal middle portion of the diagonal segment  832   d  thereby undoing a completed rotation of dial  830  (e.g., bias mechanism  881  and/or the geometry of an assembled cap subassembly  810  may be configured to not enable such a force, thereby ensuring that a completed rotation of dial  830  is not reversed by such movement of extender  847   e  diagonally upwardly beyond such a shallower portion of a diagonal segment  832   d ). Groove  832  may be provided with any suitable profile that may be gradual or somewhat step wise between different depths for providing any suitable feel or performance of cap subassembly  810 . The number of vertical segments  832   v , which may be slightly tilted and not completely vertical, may be equal to the number of different indicia that may be rotatably aligned with a passageway for visibility by a user. The angle of each diagonal segment  832   d  may be based on the number of vertical segments  832   v  and the circumference or other suitable size of the surface along which groove  832  may be provided. 
     FIG.  22  (Assembly  900 ) 
       FIG. 22  shows another illustrative bottle container assembly  900 , which may be similar to assembly  800  of  FIGS. 15-21  but may include a bias mechanism that extends between a closure and a push button. Assembly  900  of  FIG. 22  may include one or more similar components to assembly  800  of  FIGS. 15-21 , with components of assembly  900  of  FIG. 22  being labeled with “9xx” reference labels that may correspond to the “8xx” reference labels of the labeled components of assembly  800  of  FIGS. 15-21 , where differences therebetween may be described below. As shown, assembly  900  may include a bottle  990  and a cap  910  that may be coupled to bottle  990  for forming a closed container that may safely hold content therein.  FIG. 22  may show cap subassembly  910  in a second or tensioned position, which may be similar to the position of cap subassembly  810  of  FIG. 18 . Cap  910  may include a closure  920 , a dial  930 , a push button  944 , and a biasing mechanism  981 . Closure  920  of cap  910  may include a closure body that may include one or more side walls  925  that may extend from an at least partially closed top end  921  to an at least partially open bottom end  929  for defining an interior closure space  923 . Dial  930  of cap  910  may include a dial body that may include one or more side walls  935  that may extend from an at least partially closed top end  931  to an at least partially open bottom end  939 . Unlike dial  830 , dial  930  may be configured to be coupled (e.g., permanently or removably) to closure  920 , such that, for example, closure  920  may prevent dial  930  from moving (e.g., along the Z-axis). For example, dial  930  may include at least one closure attachment feature (e.g., the shape of an exterior surface of side wall(s)  935  of dial  930 ) and closure  920  may include at least one dial attachment feature  922  (e.g., one or more grooves or female threads protruding from an interior surface of closure  920 ), where dial  930  may snap into or otherwise fit dial  930  within dial attachment feature  922  for securing dial  930  within closure space  923 . Dial attachment feature  922  may be positioned above one or more button interaction features  922   b  and bottle attachment feature  928  within closure space  923  of closure  920  such that dial  930  may be coupled to closure  920  while still enabling bottle attachment feature  928  to removably couple closure  920  to bottle  990 . Unlike dial  830 , dial  930  may include an opening  932  through a portion of top end  931 , such that biasing mechanism  881  may extend through opening  932  between an interior surface of top  921  of closure  920  and a portion of button  944  (e.g., along and/or about axis A). 
     FIG.  23  (Assembly  1000 ) 
       FIG. 23  shows another illustrative bottle container assembly  1000 , which may be similar to assembly  800  of  FIGS. 15-21  but may include a base that may be operative to guide an external force applied to a push button. Assembly  1000  of  FIG. 23  may include one or more similar components to assembly  800  of  FIGS. 15-21 , with components of assembly  1000  of  FIG. 23  being labeled with “10xx” reference labels that may correspond to the “8xx” reference labels of the labeled components of assembly  800  of  FIGS. 15-21 , where differences therebetween may be described below. As shown, assembly  1000  may include a bottle (not shown) and a cap  1010  that may be coupled to the bottle for forming a closed container that may safely hold content therein.  FIG. 23  may show cap subassembly  1010  in a second or tensioned position, which may be similar to the position of cap subassembly  810  of  FIG. 18 . Cap  1010  may include a closure  1020 , a dial  1030 , a push button  1044 , and a biasing mechanism  1081 . Closure  1020  of cap  1010  may include a closure body that may include one or more side walls  1025  that may extend from an at least partially closed top end  1021  to an at least partially open bottom end  1029  for defining an interior closure space  1023 . Dial  1030  of cap  1010  may include a dial body that may include one or more side walls  1035  that may extend from an at least partially closed top end  1031  to an at least partially open bottom end  1039 . Button  1044  may include at least one closure interaction feature  1046  and closure  1020  may include at least one button interaction feature  1022   b . An interior surface of top end  1021  of closure  1020  may include any suitable dial movement feature  1027  and an exterior surface of top end  1031  of dial  1030  may include any suitable closure movement feature  1037 , where such features  1027  and  1037  may interact with one another to at least partially define an axis of rotation of dial  1030  with respect to closure  1020  (e.g., axis A) or otherwise aid or limit such movement (e.g., by preventing or limiting movement of dial  1030  along the X-axis and/or along the Y-axis within closure space  1023 ), for example, where feature  1027  may be a nub that may extend into an opening  1037  through top end  1031  of dial  1030  and may extend into a portion of biasing mechanism  1081  (e.g., through a central portion of a spring) for at least partially limiting the movement of at least a portion of biasing mechanism  1081  with respect to closure  1020  and/or with respect to dial  1030 . 
     Unlike cap subassembly  810 , cap subassembly  1010  may include a base  1070  that may include a base body that may include one or more side walls  1075  that may extend from an at least partially closed top end  1071  to an at least partially closed bottom end  1079 . Base  1070  may be configured to be coupled (e.g., permanently or removably) to closure  1020 , such that, for example, base  1070  and closure  1020  may together define at least a portion of a space within which dial  1030  and button  1044  may be positioned. For example, base  1070  may include at least one closure attachment feature (e.g., the shape of an exterior surface of side wall(s)  1075  of base  1070 ) and closure  1020  may include at least one base attachment feature  1024  (e.g., one or more grooves or female threads protruding from an interior surface of closure  1020 ), where base  1070  may snap into or otherwise fit base  1070  within base attachment feature  1024  for securing base  1070  within closure space  1023 , which may thereby define a reduced space between closure  1020  and base  1070 . Base attachment feature  1024  may be positioned above bottle attachment feature  1028  within closure space  1023  of closure  1020  such that base  1070  may be coupled to closure  1020  while still enabling bottle attachment feature  1028  to removably couple closure  1020  to a bottle (not shown). While closure space  1023  may be defined by the interior surface(s) of side wall(s)  1025 , top end  1021 , and bottom end  1029  of closure  1020 , a base space  1083   b  may be defined by the interior surface(s) of side wall(s)  1025  and top end  1021  of closure  1020  as well as by base  1070 , such that base space  1083   b  may be a portion of closure space  1023 . Base  1070  may be made of any suitable material or combination of materials and may be of any suitable dimensions. Base  1070  may include at least one opening  1077  therethrough between top  1071  and bottom  1079 , where opening  1077  may be operative to enable a remote object (e.g., a fingertip of user U) to be inserted therethrough for applying a force on button  1044  (e.g., in the +Z-direction) for moving cap subassembly  1010  to a second or tensioned position of  FIG. 23 . For example, as shown, opening  1077  may be positioned directly underneath biasing mechanism  1081  for guiding user U to apply such a force to a portion of button  1044  that may provide an external force interface (e.g., bottom  1049 ) that is aligned with biasing mechanism  1081  and/or axis A for promoting the application of the most effective user force for achieving the second position of  FIG. 23  (e.g., rather than a user force that may be applied off-axis from axis A and/or not along the center of biasing mechanism  1081 ). 
     FIG.  24  (Assembly  1100 ) 
       FIG. 24  shows another illustrative bottle container assembly  1100 , which may be similar to assembly  800  of  FIGS. 15-21  but may include a base that may be operative to guide an external force applied to a push button, that may be operative to prevent rotation of the push button, and/or that may be operative to enable a bottle to apply a force to the push button. Assembly  1100  of  FIG. 24  may include one or more similar components to assembly  800  of  FIGS. 15-21 , with components of assembly  1100  of  FIG. 24  being labeled with “11xx” reference labels that may correspond to the “8xx” reference labels of the labeled components of assembly  800  of  FIGS. 15-21 , where differences therebetween may be described below. As shown, assembly  1100  may include a bottle  1190  and a cap  1110  that may be coupled to bottle  1190  for forming a closed container that may safely hold content therein.  FIG. 24  may show cap subassembly  1110  in a second or tensioned position, which may be similar to the position of cap subassembly  810  of  FIG. 18 . Cap  1110  may include a closure  1120 , a dial  1130 , a push button  1144  with side wall(s)  1145  extending between a top end and a bottom end  1149 , and a biasing mechanism  1181 . Closure  1120  of cap  1110  may include a closure body that may include one or more side walls  1125  that may extend from an at least partially closed top end  1121  to an at least partially open bottom end  1129  for defining an interior closure space  1123 . Dial  1130  of cap  1110  may include a dial body that may include one or more side walls  1135  that may extend from an at least partially closed top end  1131  to an at least partially open bottom end  1139 . An interior surface of top end  1121  of closure  1120  may include any suitable dial movement feature  1127  and an exterior surface of top end  1131  of dial  1130  may include any suitable closure movement feature  1137 , where such features  1127  and  1137  may interact with one another to at least partially define an axis of rotation of dial  1130  with respect to closure  1120  (e.g., axis A) or otherwise aid or limit such movement (e.g., by preventing or limiting movement of dial  1130  along the X-axis and/or along the Y-axis within closure space  1123 ), for example, where feature  1127  may be a nub that may extend into a cut out or notch  1137  in top end  1131  of dial  1130 . 
     Unlike cap subassembly  810 , but like cap subassembly  1010 , cap subassembly  1110  may include a base  1170  that may include a base body that may include one or more side walls  1175  that may extend from an at least partially closed top end  1171  to an at least partially closed bottom end  1179 . Base  1170  may be configured to be coupled (e.g., permanently or removably) to closure  1120 , such that, for example, base  1170  and closure  1120  may together define at least a portion of a base space  1183   b  within which dial  1130  and button  1144  may be positioned. For example, base  1170  may include at least one closure attachment feature (e.g., the shape of an exterior surface of side wall(s)  1175  of base  1170 ) and closure  1120  may include at least one base attachment feature  1124  (e.g., one or more grooves or female threads protruding from an interior surface of closure  1120 ), where base  1170  may snap into or otherwise fit base  1170  within base attachment feature  1124  for securing base  1170  within closure space  1123 , which may thereby define a reduced space between closure  1120  and base  1170 . Base attachment feature  1124  may be positioned above bottle attachment feature  1128  within closure space  1123  of closure  1120  such that base  1170  may be coupled to closure  1120  while still enabling bottle attachment feature  1128  to removably couple closure  1120  to a bottle feature  1192  of bottle  1190 . While closure space  1123  may be defined by the interior surface(s) of side wall(s)  1125 , top end  1121 , and bottom end  1129  of closure  1120 , a base space  1183   b  may be defined by the interior surface(s) of side wall(s)  1125  and top end  1121  of closure  1120  as well as by base  1170 , such that base space  1183   b  may be a portion of closure space  1123 . Base  1170  may be made of any suitable material or combination of materials and may be of any suitable dimensions. Base  1170  may include at least one opening  1177  therethrough between top  1171  and bottom  1179 , which may be similar to opening  1077  of cap subassembly  1010  of  FIG. 23 . 
     Rather than closure  1120  including any button interaction feature (e.g., like button interaction feature  822   b  of cap subassembly  810  for preventing rotation of the push button), button  1144  may instead interact with a portion of base  1170  for preventing such rotation. For example, button  1144  may include at least one closure interaction feature  1146  (e.g., a feature extending outwardly from an exterior surface of side wall(s)  1145  or bottom  1149  of button  1144  and then downwardly through at least one associated base opening  1177   b  of base  1177 ), where the portion of one or more closure interaction features  1146  extending through an associated base opening  1177   b  may prevent rotation of button  1144  with respect to base  1170  and, thus, closure  1120 . Moreover, a portion of one or more closure interaction features  1146  extending through an associated base opening  1177   b  may be exposed to interacting with a portion of bottle  1190  (e.g., top  1191 ) for providing an external force interface when bottle  1190  may be coupled to cap subassembly  1110 , where such interaction may apply an upward force (e.g., in the ±Z-direction) for moving button  1144  to and/or holding button  1144  at its second position of  FIG. 24 . 
     FIG.  25  (Assembly  1200 ) 
       FIG. 25  shows another illustrative bottle container assembly  1200 , which may be similar to assembly  800  of  FIGS. 15-21  but may include a base that may be operative to guide an external force applied to a push button, that may be operative to prevent rotation of the push button, and/or that may be operative to enable a bottle to apply a force to the push button, while also enabling indicia on a bottom portion of a dial to be exposed through the push button. Assembly  1200  of  FIG. 25  may include one or more similar components to assembly  800  of  FIGS. 15-21 , with components of assembly  1200  of  FIG. 25  being labeled with “12xx” reference labels that may correspond to the “8xx” reference labels of the labeled components of assembly  800  of  FIGS. 15-21 , where differences therebetween may be described below. As shown, assembly  1200  may include a bottle  1290  and a cap  1210  that may be coupled to bottle  1290  for forming a closed container that may safely hold content therein.  FIG. 25  may show cap subassembly  1210  in a second or tensioned position, which may be similar to the position of cap subassembly  810  of  FIG. 18 . Cap  1210  may include a closure  1220 , a dial  1230 , a push button  1244  with side wall(s)  1245  extending between a top end  1241  and a bottom end  1249 , and a biasing mechanism  1281 . Closure  1220  of cap  1210  may include a closure body that may include one or more side walls  1225  that may extend from an at least partially closed top end  1221  to an at least partially open bottom end  1229  for defining an interior closure space  1223 . Dial  1230  of cap  1210  may include a dial body that may include one or more side walls  1235  that may extend from an at least partially closed top end  1231  to an at least partially open bottom end  1239 . Any suitable feature(s) of dial  1130  may interact with any other suitable feature(s) of cap  1210  to at least partially define an axis of rotation of dial  1230  with respect to closure  1220  (e.g., axis A) or otherwise aid or limit such movement (e.g., by preventing or limiting movement of dial  1230  along the X-axis and/or along the Y-axis within closure space  1223 ). 
     Unlike cap subassembly  810 , but like cap subassembly  1110 , cap subassembly  1210  may include a base  1270  that may include a base body that may include one or more side walls  1275  that may extend from an at least partially closed top end  1271  to an at least partially closed bottom end  1279 . Base  1270  may be configured to be coupled (e.g., permanently or removably) to closure  1220 , such that, for example, base  1270  and closure  1220  may together define at least a portion of a base space  1283   b  within which dial  1230  and button  1244  may be positioned. For example, base  1270  may include at least one closure attachment feature (e.g., the shape of an exterior surface of side wall(s)  1275  of base  1270 ) and closure  1220  may include at least one base attachment feature  1224  (e.g., one or more grooves or female threads protruding from an interior surface of closure  1220 ), where base  1270  may snap into or otherwise fit base  1270  within base attachment feature  1224  for securing base  1270  within closure space  1223 , which may thereby define a reduced space between closure  1220  and base  1270 . Base attachment feature  1224  may be positioned above bottle attachment feature  1228  within closure space  1223  of closure  1220  such that base  1270  may be coupled to closure  1220  while still enabling bottle attachment feature  1228  to removably couple closure  1220  to a bottle feature  1292  of bottle  1290 . While closure space  1223  may be defined by the interior surface(s) of side wall(s)  1225 , top end  1221 , and bottom end  1229  of closure  1220 , base space  1283   b  may be defined by the interior surface(s) of side wall(s)  1225  and top end  1221  of closure  1220  as well as by base  1270 , such that base space  1283   b  may be a portion of closure space  1223 . Base  1270  may be made of any suitable material or combination of materials and may be of any suitable dimensions. Base  1270  may include at least one opening  1277  therethrough between top  1271  and bottom  1279 , which may be similar to opening  1077  of cap subassembly  1010  of  FIG. 23 . 
     Rather than closure  1220  including any button interaction feature (e.g., like button interaction feature  822   b  of cap subassembly  810  for preventing rotation of the push button), button  1244  may instead interact with a portion of base  1270  for preventing such rotation. For example, button  1244  may include at least one closure interaction feature  1246  (e.g., a feature extending outwardly from an exterior surface of side wall(s)  1245  or bottom  1249  of button  1244  and then downwardly through at least one associated base opening  1277   b  of base  1277 ), where the portion of one or more closure interaction features  1246  extending through an associated base opening  1277   b  may prevent rotation of button  1244  with respect to base  1270  and, thus, closure  1220 . Moreover, a portion of one or more closure interaction features  1246  extending through an associated base opening  1277   b  may be exposed to interacting with a portion of bottle  1290  (e.g., top  1291 ) for providing an external force interface when bottle  1290  may be coupled to cap subassembly  1210 , where such interaction may apply an upward force (e.g., in the ±Z-direction) for moving button  1244  to and/or holding button  1244  at its second position of  FIG. 25 . 
     Moreover, closure indicia passageways  1226  may include not only at least one top closure indicia passageway  1226   t  that may be provided through the wall of top end  1221  of closure  1220  and/or at least one side closure indicia passageway  1226   s  that may be provided through at least one side wall  1225  of closure  1220 , closure indicia passageways may also include at least one button indicia passageway  1246   b  through a portion of one or more closure interaction features  1246  of button  1244  and/or at least one base indicia passageway  1276  through a portion of base  1270 . Each closure indicia passageway may be a hollow opening through a wall or other portion of closure  1220 , button  1244 , and/or base  1270  or may be such an opening that may be covered by or otherwise configured to include a transparent or translucent material or any other suitable object (e.g., a magnifying glass  1226   tm  and/or  1226   sm  and/or  1246   bm  and/or  1276   m ) that may enable communication of information therethrough to a user of assembly  1210 . Dial  1230  may include any suitable dial indicia  1236  that may be positioned on any suitable portions of dial  1230  for selective display to a user of assembly  1210 . As shown, dial indicia  1236  may include top dial indicia  1236   t  that may be provided on an exterior surface of top end  1231  of dial  1230  (e.g., for alignment with passageway  1226   t ), and/or side dial indicia  1236   s  that may be provided on an exterior surface of one or more side walls  1235  (e.g., for alignment with passageway  1226   t ) and/or bottom dial indicia  1236   b  that may be provided on an exterior surface of bottom end  1239  of dial  1230  (e.g., for alignment with passageway  1246   b  and/or passageway  1276 ). 
     FIG.  26  (Assembly  1300 ) 
       FIG. 26  shows another illustrative bottle container assembly  1300 , which may be similar to assembly  800  of  FIGS. 15-21  but may include a base that may be operative to guide an external force applied to a push button, that may be operative to prevent rotation of the push button, and/or that may be operative to enable a bottle to apply a force to the push button, while also enabling a push button to interact with a groove on an exterior or outwardly facing surface of a dial. Assembly  1300  of  FIG. 26  may include one or more similar components to assembly  800  of  FIGS. 15-21 , with components of assembly  1300  of  FIG. 26  being labeled with “13xx” reference labels that may correspond to the “8xx” reference labels of the labeled components of assembly  800  of  FIGS. 15-21 , where differences therebetween may be described below. As shown, assembly  1300  may include a bottle (not shown) and a cap  1310  that may be coupled to the bottle for forming a closed container that may safely hold content therein.  FIG. 26  may show cap subassembly  1310  in a second or tensioned position, which may be similar to the position of cap subassembly  810  of  FIG. 18 . Cap  1310  may include a closure  1320 , a dial  1330 , a push button  1344  with side wall(s)  1345  extending between a top end  1341  and a bottom end  1349 , and a biasing mechanism  1381 . Closure  1320  of cap  1310  may include a closure body that may include one or more side walls  1325  that may extend from an at least partially closed top end  1321  to an at least partially open bottom end  1329  for defining an interior closure space  1323 . Any suitable feature(s) of dial  1330  may interact with any other suitable feature(s) of cap  1310  to at least partially define an axis of rotation of dial  1330  with respect to closure  1320  (e.g., axis A) or otherwise aid or limit such movement (e.g., by preventing or limiting movement of dial  1330  along the X-axis and/or along the Y-axis within closure space  1323 ). 
     Unlike cap subassembly  810 , but like cap subassembly  1110 , cap subassembly  1310  may include a base  1370  that may include a base body that may include one or more side walls  1375  that may extend from an at least partially closed top end  1371  to an at least partially closed bottom end  1379 . Base  1370  may be configured to be coupled (e.g., permanently or removably) to closure  1320 , such that, for example, base  1370  and closure  1320  may together define at least a portion of a base space  1383   b  within which dial  1330  and button  1344  may be positioned. For example, base  1370  may include at least one closure attachment feature (e.g., the shape of an exterior surface of side wall(s)  1375  of base  1370 ) and closure  1320  may include at least one base attachment feature  1324  (e.g., one or more grooves or female threads protruding from an interior surface of closure  1320 ), where base  1370  may snap into or otherwise fit base  1370  within base attachment feature  1324  for securing base  1370  within closure space  1323 , which may thereby define a reduced space between closure  1320  and base  1370 . Base attachment feature  1324  may be positioned above bottle attachment feature  1328  within closure space  1323  of closure  1320  such that base  1370  may be coupled to closure  1320  while still enabling bottle attachment feature  1328  to removably couple closure  1320  to a bottle feature of the bottle. Base  1370  may include at least one opening  1377  therethrough between top  1371  and bottom  1379 , which may be similar to opening  1077  of cap subassembly  1010  of  FIG. 23 . 
     Rather than closure  1320  including any button interaction feature (e.g., like button interaction feature  822   b  of cap subassembly  810  for preventing rotation of the push button), button  1344  may instead interact with a portion of base  1370  for preventing such rotation. For example, button  1344  may include at least one closure interaction feature  1346  (e.g., a feature extending outwardly from an exterior surface of side wall(s)  1345  or bottom  1349  of button  1344  and then downwardly through at least one associated base opening  1377   b  of base  1377 ), where the portion of one or more closure interaction features  1346  extending through an associated base opening  1377   b  may prevent rotation of button  1344  with respect to base  1370  and, thus, closure  1320 . Moreover, a portion of one or more closure interaction features  1346  extending through an associated base opening  1377   b  may be exposed to interacting with a portion of the bottle (e.g., a top of the bottle) for providing an external force interface when the bottle may be coupled to cap subassembly  1310 , where such interaction may apply an upward force (e.g., in the ±Z-direction) for moving button  1344  to and/or holding button  1344  at its second position of  FIG. 26 . 
     Dial  1330  of cap  1310  may include a dial body that may include one or more side walls  1335  that may extend from an at least partially closed top end  1331  to an at least partially open bottom end  1339 , where side indicia  1336   s  may be provided on an exterior surface of side wall(s)  1335 . Rather than a portion of button  1344  interacting with a groove on an interior surface of wall(s)  1335 , one or more second internal side wall(s)  1335   i  may extend downwardly from top end  1331  internal to wall(s)  1335  (e.g., closer to but also about axis A) and at least one extender  1347   e  of button  1344  may extend into a groove  1332  of dial  1330  that may be provided in an exterior surface of wall(s)  1335   i  about axis A. Therefore, rather than extending outwardly from the button into an interior surface of the dial (e.g., as extender  847   e  may extend outwardly away from button  844  and axis A into groove  832  in an interior surface of dial  830 ), extender  1347   e  may extend inwardly away from button  1344  and towards axis A into groove  1332  in an exterior surface of dial  1330 . 
     FIG.  27  (Assembly  1400 ) 
       FIG. 27  shows another illustrative bottle container assembly  1400 , which may be similar to assembly  800  of  FIGS. 15-21  but may include a dial with an axis of rotation that may be offset from an axis of rotation of a closure for coupling to a bottle. Assembly  1400  of  FIG. 27  may include one or more similar components to assembly  800  of  FIGS. 15-21 , with components of assembly  1400  of  FIG. 27  being labeled with “14xx” reference labels that may correspond to the “8xx” reference labels of the labeled components of assembly  800  of  FIGS. 15-21 , where differences therebetween may be described below. As shown, assembly  1400  may include a bottle (not shown) and a cap subassembly  1410  including a closure  1420  that may be coupled to the bottle for forming a closed container that may safely hold content therein (e.g., by rotating closure  1420  with respect to the bottle about a bottle axis AB (e.g., in the direction of arrow R 1  and/or arrow R 2 ) that may extend through the middle of cap subassembly  1410 ). Unlike cap subassembly  810  where an axis of rotation of closure  810  for coupling closure  810  to bottle  890  may be the same as an axis of rotation of dial  830  within closure  810  (e.g., axis A of assembly  810 ), cap subassembly  1410  may include an axis A about which dial  1430  may rotate (e.g., in the direction of arrow R 1  and/or arrow R 2 ), where axis A is offset from axis AB (e.g., axis A may be parallel to but not co-linear with axis AB). Rotation of dial  1430  may align particular dial indicia with one or more particular passageways through closure  1420  (e.g., indicia  1436   t  with passageway  1426   t  and/or indicia  1436   s  with passageway  1426   s ). This cap subassembly  1410  may therefore be provided with a dial  1430  of a significantly smaller magnitude than that of closure  1420 . 
     FIGS.  28 - 32  (Assembly  1500 ) 
       FIGS. 28-32  show another illustrative bottle container assembly  1500 , which may be similar to assembly  800  of  FIGS. 15-21  but may not include a push button distinct from a dial. Assembly  1500  of  FIGS. 28-32  may include one or more similar components to assembly  800  of  FIGS. 15-21 , with components of assembly  1500  of  FIGS. 28-32  being labeled with “15xx” reference labels that may correspond to the “8xx” reference labels of the labeled components of assembly  800  of  FIGS. 15-21 , where differences therebetween may be described below. As shown, assembly  1500  may include a bottle  1590  and a cap  1510  that may be coupled to bottle  1590  for forming a closed container that may safely hold content therein. For example, bottle  1590  may include a bottle body that may include one or more side walls  1595  that may extend from a closed bottom end  1599  to an at least partially open top end  1591  for defining an interior bottle space  1593 . Bottle  1590  may be configured such that a user may insert content  1597  through open end  1591  into bottle space  1593  (e.g., along the −Z direction) and/or may remove content  1597  from bottle space  1593  through open end  1591  (e.g., along the ±Z direction). Bottle  1590  may be any suitable container portion that may be configured to hold any suitable content  1597  in any suitable way. Bottle  1590  may be made of any suitable material or combination of materials and may be of any suitable dimensions. 
     Cap  1510  may be configured to be removably coupled to bottle  1590 , such that cap  1510  may cover open end  1591  for preventing a user from accessing bottle space  1593  when cap  1510  is coupled to bottle  1590 , and such that cap  1510  may not cover at least a portion of open end  1591  for enabling a user to access bottle space  1593  when cap  1510  is not coupled to bottle  1590 . Assembly  1500  may be configured in any suitable way for enabling cap subassembly  1510  to be removably coupled to bottle  1590 . As just one example, bottle  1590  may include at least one cap attachment feature  1592  and cap  1510  may include at least one bottle attachment feature  1528 , where cap attachment feature  1592  and bottle attachment feature  1528  may be any suitable combination of reciprocal or otherwise related features that may be configured to interact with each other for removably coupling cap  1510  to bottle  1590  (e.g., threads, snaps, notches, clips, location or transition fits, etc.). Bottle  1590  may also include a lip  1594 , which may protrude from an exterior surface of body  1595  below cap attachment feature  1592 , where lip  1594  may be configured to suspend cap subassembly  1510  by at least a certain distance above the closed end. Cap attachment feature  1592  and/or lip  1594  may ensure a specific relationship between cap  1510  and bottle  1590  when cap  1510  is coupled to bottle  1590 . 
     Cap  1510  may include a closure  1520 , a dial  1530 , and a biasing mechanism  1581 . Closure  1520  of cap  1510  may include a closure body that may include one or more side walls  1525  that may extend from an at least partially closed top end  1521  to an at least partially open bottom end  1529  for defining an interior closure space  1523 . Closure  1520  may also include one or more closure indicia passageways  1526  through any suitable portions of closure  1520  for selectively exposing to a user one or more other portions of cap subassembly  1510  (e.g., portions of dial  1530 , as described below). As shown, closure indicia passageways  1526  may include at least one top closure indicia passageway  1526   t  that may be provided through the wall of top end  1521  of closure  1520  and/or at least one side closure indicia passageway  1526   s  that may be provided through at least one side wall  1525  of closure  1520 . Each closure indicia passageway  1526  may be a hollow opening through a wall or other portion of closure  1520  or may be such an opening that may be covered by or otherwise configured to include a transparent or translucent material or any other suitable object (e.g., a magnifying glass  1526   tm  and/or  1526   sm ) that may enable communication of information therethrough to a user of assembly  1500 . Closure  1520  may be made of any suitable material or combination of materials and may be of any suitable dimensions. 
     Dial  1530  of cap  1510  may include a dial body that may include one or more side walls  1535  that may extend from an at least partially closed top end  1531  to an at least partially closed bottom end  1539 . Dial  1530  may define an interior dial space  1533 , which may be accessible via a dial opening  1538 , which may be provided through any suitable portion of the dial body, such as through top end  1531 . Unlike assembly  800  in which a groove is provided in a portion of dial  830 , at least one groove  1532  may be provided along any suitable surface of closure  1520  of assembly  1500  rather than along a surface of dial  1530 , such as along an interior surface  1534  of one or more side walls  1525  of closure  1520 , where closure groove  1532  may be accessible within closure space  1523  (e.g., by a portion of dial  1530 , as described below). Dial  1530  may include any suitable dial indicia  1536  that may be positioned on any suitable portions of dial  1530  for selective display to a user of assembly  1500 . As shown, dial indicia  1536  may include top dial indicia  1536   t  that may be provided on one or more exterior surface portions of top end  1531  of dial  1530 , and/or side dial indicia  1536   s  that may be provided on one or more exterior surface portions of one or more side walls  1535 . Dial  1530  may be configured to fit at least partially within closure space  1523 , such that dial  1530  may be moved (e.g., rotated about axis A) within closure space  1523  with respect to closure  1520  for selectively aligning different dial indicia  1536  of dial  1530  with a closure indicia passageway  1526  of closure  1520 . Dial  1530  may be made of any suitable material or combination of materials and may be of any suitable dimensions. 
     Rather than including a distinct button component, like button  844  of assembly  800 , certain features may be provided by dial  1530  for interacting with groove  1532  of closure  1520  for enabling rotation of dial  1530  with respect to closure  1520 . As shown, dial  1530  may include one or more closure interaction features  1547  that may be operative to interact with closure groove  1532  of closure  1520  for rotating dial  1530  within closure space  1523 . Unlike assembly  800  in which button  844  may be pushed linearly in the Z-direction with respect to closure  820  but prevented from rotating with respect to closure  820 , the interaction of one or more closure interaction features  1547  of dial  1530  with closure groove  1532  of closure  1520  of assembly  1500  may enable dial  1530  not only to be pushed linearly in the Z-direction with respect to closure  1520  but also to be rotated with respect to closure  1520  within closure space  1523 , such as, for example, between a first “low” position of  FIG. 31  and/or  FIG. 33  to a second “high” position of  FIG. 32 ). The interaction of at least one closure interaction feature  1547  with at least one closure groove  1532  may enable rotational movement of dial  1530  within closure space  1523  (e.g., about axis A) with respect to closure  1520  after suitable linear movement of dial  1530  within closure space  1523  (e.g., along the Z-axis) with respect to closure  1520 , for example, such that different indicia  1536  of dial  1530  may be rotated into alignment with a passageway  1526  of closure  1520 . As shown, groove  1532  may extend along interior surface  1534  of closure  1520  about at least a portion of axis A, and, when dial  1530  is coupled to closure  1520 , at least a portion of each closure interaction feature  1547  may extend into at least a portion of closure groove  1532 . Each closure interaction feature  1547  may extend adjacently and/or parallel to one or more portions of side wall  1535  away from bottom end  1539  (e.g., in the +Z-direction) to a top end  1547   t  of that closure interaction feature  1547 . At some location along the length of closure interaction feature  1547 , an extender portion  1547   e  may extend from the main body of interaction feature  1547  (e.g., outwardly away from axis A) for extending at least partially into groove  1532 . In some embodiments, top end  1547   t  of a closure interaction feature  1547  may be a free end for enabling deflection of extender  1547   e  towards and/or away from axis A, for example, such that extender  1547   e  may be enabled to snap or otherwise fit into groove  1532 . In some embodiments, extender  1547   e  may extend away from the main body of interaction feature  1547  at top end  1547   t . In other embodiments, extender  1547   e  may extend away from the main body of interaction feature  1547  at some point below top end  1547   t , for example, such that top end  1547   t  may be operative to interact with an interior surface of top  1521  of closure  1520  (e.g., as described with respect to assembly  800  of  FIG. 19  but not shown by assembly  1500 ), which may at least partially limit the linear movement of dial  1530  in the +Z-direction within closure space  1523 . 
     Biasing mechanism  1581  may be positioned at any suitable position within closure space  1523  for biasing at least a portion of dial  1530  away from top end  1521  of closure  1520  (e.g., in the −Z-direction), for example, to at least partially control the linear movement of dial  1530  within closure space  1523 . Biasing mechanism  1581  may be any suitable component or combination of components, such as any suitable spring, that may be operative to be compressed or tensioned for enabling movement of at least a portion of dial  1530  towards top end  1521  of closure  1520  (e.g., in the +Z-direction) when a suitable amount of force is applied to dial  1530  in that direction by an object remote from cap subassembly  1510  (e.g., a user U or bottle  1590 ), while also being operative to decompress or relax for moving at least a portion of dial  1530  away from top end  1521  (e.g., in the −Z-direction) when such a suitable amount of force is not applied to dial  1530  by such a remote object. As shown, for example, biasing mechanism  1581  may include at least one spring that may be operative to be compressed from a first state (e.g., a first expanded or relaxed state of  FIG. 30  and/or  FIG. 32 , whereby biasing mechanism  1581  may have a first length B 1  along the Z-axis when no external force is applied to dial  1530 ) to a second state (e.g., a compressed or tensioned state of  FIG. 31 , whereby biasing mechanism  1581  may have a second length B 2  along the Z-axis that is shorter than length B 1 ) when a suitable external force is applied to dial  1530  in the +Z-direction (e.g., by user U or bottle  1590 , as described below in more detail) and that may be operative to expand from the second state to the first state when no such suitable external force is applied to dial  1530 . As shown, biasing mechanism  1581  may be positioned within closure space  1523  and at least partially within dial space  1533  for extending between an interior surface of top  1521  of closure  1520  and an interior surface of bottom  1539  of dial  1530  (e.g., along and/or about axis A). In other embodiments, biasing mechanism  1581  may be positioned within closure space  1523  but not dial space  1533  for extending between an interior surface of top  1521  of closure  1520  and an exterior surface of top  1531  of dial  1530  (e.g., similarly to described below with respect to  FIG. 35 ). 
     Closure groove  1532  may extend along at least a portion of the interior of closure  1520  about at least a portion of axis A. Groove  1532  may have any suitable shape for translating movement of dial  1530  (e.g., extender  1547   e ) towards and/or away from top  1521  of closure  1520  (e.g., movement of dial  1530  along or substantially along the Z-axis) into rotation or other suitable movement of dial  1530  about axis A. For example, like groove  832  of assembly  800 , as shown, groove  1532  may include two or more vertical or substantially vertical segments  1532   v  (e.g., extending along or substantially along a Z-axis) and at least two diagonal segments  1532   d , where each diagonal segment  1532   d  may couple an upper portion  1532   u  of a first vertical segment  1532   v  to a lower portion  1532   l  of a second vertical segment  1532   v  that may be adjacent the first vertical segment  1532   v . Different stages of use of cap subassembly  1510  may be shown in  FIGS. 30-32  and may illustrate how the geometry of groove  1532  may at least partially dictate movement between such stages. 
     As shown in  FIG. 30 , cap subassembly  1510  may be in a first state, where no force external to cap subassembly  1510  may be applied to any portion of cap subassembly  1510 , such that such a first state of cap subassembly  1510  may be referred to as a relaxed state or an expanded state (e.g., as biasing mechanism  1581  may be in an expanded state of a first length B 1 , which may be limited from expanding to a greater length by one or more of a biasing characteristic or geometry of biasing mechanism  1581 , and/or the interaction of at least one extender  1547   e  of dial  1530  with a bottom of a respective vertical segment  1532   v  of groove  1532  of closure  1520  (e.g., at a lower portion  1532   l )). In such a first state of  FIG. 30 , a first particular side indicia (e.g., “Fri”) of side indicia  1536   s  may or may not be aligned with side passageway  1526   s  (e.g., horizontally aligned within an X-Y plane) and/or a first particular top indicia of top indicia  1536   t  may be aligned with top passageway  1526   t  (e.g., vertically aligned within a Y-Z plane), while each extender  1547   e  of dial  1530  may be positioned within a respective vertical segment  1532   v  of groove  1532  of closure  1520  (e.g., at or proximal to the lower portion  1532   l  of that vertical segment  1532   v ). 
     Next, when any suitable external force is applied to cap subassembly  1510  that may be large enough to at least overcome the biasing force of biasing mechanism  1581  for reducing the vertical length B 1  of biasing mechanism  1581 , at least a portion of dial  1530  may be moved in the +Z-direction. For example, in some embodiments, as shown in  FIG. 31 , a user U may apply a user force in the +Z-direction onto any accessible portion of dial  1530  providing an external force interface (e.g., an exterior surface of bottom  1539 ) that may reduce the vertical length of biasing mechanism  1581  to length B 2  (e.g., when cap  1510  is not coupled to bottle  1590 ). In alternative embodiments, as also shown in  FIG. 31 , when bottle  1590  is coupled to closure  1520 , a portion of bottle  1590  (e.g., top  1591 ) may be operative to apply a bottle force in the +Z-direction onto any suitable portion of dial  1530  providing an external force interface (e.g., an exterior surface of bottom  1539 ) that may reduce the vertical length of biasing mechanism  1581  to length B 2 . In any event, such an external force may provide a second state of cap subassembly  1510  of  FIG. 31 . Such a second state of cap subassembly  1510  may be referred to as a compressed state or tensioned state, as biasing mechanism  1581  may be in a compressed or tensioned state of a second reduced length B 2 , which may be limited from compressing to an even shorter length by one or more of a biasing characteristic or geometry of biasing mechanism  1581 , the interaction of at least one extender  1547   e  of dial  1530  with a top of a respective vertical segment  1532   v  of groove  1532  of closure  1520  (e.g., at an upper portion  1532   u ), the interaction of top  1547   t  of dial  1530  with a portion of closure  1520  (e.g., an interior surface of top  1521 ), and/or the interaction of bottle  1590  with closure  1520  (e.g., lip  1594  with bottom end  1529 ). In such a second state of  FIG. 31 , the first particular side indicia (e.g., “Fri”) of side indicia  1536   s  may be aligned with side passageway  1526   s  (e.g., horizontally aligned within an X-Y plane). Moreover, in such a second state of  FIG. 31 , each extender  1547   e  of dial  1530  may remain positioned within the same respective vertical segment  1532   v  of groove  1532  of closure  1520  as it was at the first state of  FIG. 30 , but at a location within that vertical segment  1532   v  that is at or proximal to the upper portion  1532   u  of that vertical segment  1532   v.    
     As shown in  FIG. 32 , cap subassembly  1510  may advance to a third state when the external force being applied to cap subassembly  1510  in its second state of  FIG. 31  is terminated or reduced a suitable amount. For example, when the external force applied by user U or bottle  1590  is at least partially reduced or removed such that bias mechanism  1581  forces each extender  1547   e  of dial  1530  in a downward direction (e.g., in the −Z-direction), the geometry of groove  1532  and its interaction with extender  1547   e  may be operative to prevent extender  1547   e  from traveling back down the same initial vertical segment  1532   v  in which extender  1547   e  was located in its second state of  FIG. 31  (e.g., in the −Z-direction) but rather may be operative to guide the travel of extender  1547   e  diagonally downwardly (e.g., in the direction of arrow D of  FIG. 30 ) along the diagonal segment  1532   d  extending from the upper portion  1532   u  of the initial vertical segment  1532   v  of the first and second states and into the lower portion  1532   l  of an adjacent new vertical segment  1532   v  for the third state of cap subassembly  1510 . Such diagonal movement of extender  1547   e  with respect to closure  1520  along groove  1532  may rotate dial  1530  about axis A from its rotational orientation of the second state of  FIG. 31  to its rotational orientation of the third state of  FIG. 32  (e.g., by an arc length equal to the arc length between the two adjacent vertical segments  1532   v ). In such a third state of  FIG. 32 , a new particular side indicia (e.g., “Sat”) of side indicia  1536   s  may or may not be aligned (e.g., horizontally aligned in an X-Y plane) with side passageway  1526   s  (e.g., as compared to “Fri” of the first state of  FIG. 30 ) and/or a new particular top indicia of top indicia  1536   t  may be aligned with top passageway  1526   t  (e.g., vertically aligned in a Y-Z plane), as each extender  1547   e  of dial  1530  may be positioned within a new respective vertical segment  1532   v  of groove  1532  of closure  1520  (e.g., at or proximal to the lower portion  1532   l  of that new vertical segment  1532   v ). Such a third state of cap subassembly  1510  of  FIG. 32  may also be referred to as a relaxed state or an expanded state (e.g., as biasing mechanism  1581  may be in an expanded state of first length B 1 , which may be limited from expanding to a greater length by one or more of a biasing characteristic or geometry of biasing mechanism  1581 , and/or the interaction of at least one extender  1547   e  of dial  1530  with a bottom of the new respective vertical segment  1532   v  of groove  1532  of closure  1520 ). Therefore, the interaction between the geometry of downwardly moving extender  1547   e  of dial  1530  and the geometry of groove  1532  of closure  1520  may rotate dial  1530  about axis A for aligning new indicia with one or more passageways for viewing by a user of cap subassembly  1510 . Although not shown in  FIGS. 28-32 , groove  1532  of closure  1520  of assembly  1510  may be provided with the same depth variation as described above with respect to assembly  800  and  FIGS. 20 and 21 . In some embodiments, it is to be noted that both useful alignment of particular side indicia of side indicia  1536   s  with side passageway  1526   s  (e.g., horizontal alignment in an X-Y plane) and useful alignment of particular top indicia of side indicia  1536   t  with top passageway  1526   t  (e.g., vertical alignment in a Y-Z plane) may only be achieved when cap subassembly  1510  is positioned in its second state of  FIG. 31  (e.g., when an external force may be provided by a user or bottle on cap subassembly  1510 ). 
     FIG.  33  (Assembly  1600 ) 
       FIG. 33  shows another illustrative bottle container assembly  1600 , which may be similar to assembly  1500  of  FIGS. 28-32  but may be configured to be in a relaxed position when a bottle is coupled to a cap assembly. Assembly  1600  of  FIG. 33  may include one or more similar components to assembly  1500  of  FIGS. 28-32 , with components of assembly  1600  of  FIG. 33  being labeled with “16xx” reference labels that may correspond to the “15xx” reference labels of the labeled components of assembly  1500  of  FIGS. 28-32 , where differences therebetween may be described below. As shown, assembly  1600  may include a bottle  1690  and a cap  1610  that may be coupled to bottle  1690  for forming a closed container that may safely hold content therein.  FIG. 33  may show cap subassembly  1610  in a first or relaxed position, which may be similar to the position of cap subassembly  1510  of  FIG. 30 . Cap  1610  may include a closure  1620 , a dial  1630 , and a biasing mechanism  1681 . Closure  1620  of cap  1610  may include a closure body that may include one or more side walls  1625  that may extend from an at least partially closed top end  1621  to an at least partially open bottom end  1629  for defining an interior closure space  1623 . Dial  1630  of cap  1610  may include a dial body that may include one or more side walls  1635  that may extend from an at least partially open top end  1631  to an at least partially closed bottom end  1639 . Unlike assembly  1500 , assembly  1600  may be configured such that, when a bottle is coupled to the cap subassembly, the bottle does not exert a force on the dial for moving the dial to a tensioned position. For example, unlike  FIG. 30  that may show cap subassembly  1510  in a tensioned second position when bottle  1590  is coupled to closure  1520  (e.g., due to a force exerted by bottle  1590  on dial  1530 ), assembly  1600  may be configured such that cap subassembly  1610  may be in a first relaxed position when bottle  1690  is coupled to closure  1620  (e.g., via cap attachment feature  1692  and bottle attachment feature  1628 ) as bottle  1690  may not be exerting any force on dial  1630  or a force that may overcome a downward force on dial  1630  by biasing mechanism  1681 . Therefore, unlike cap subassembly  1510  that may enable the rotation of dial  1530  for updating the particular indicia  1536  visible to a user through coupling and uncoupling cap subassembly  1510  from bottle  1590  (e.g., automatic dial rotation when a container assembly is opened and/or closed by decoupling/coupling a cap subassembly to a bottle), cap subassembly  1610  may not enable such rotation due to coupling and uncoupling cap subassembly  1610  from bottle  1690  but may instead require active user force be applied to dial  1630  for such rotation (e.g., manual user force applied to a user extension feature  1639   u  that may extend downwardly from bottom end  1639  of dial  1630  at a suitable location (e.g., a location along the same Z-axis as axis A and/or biasing mechanism  1681 ) for providing an external force interface). 
     FIG.  34  (Assembly  1700 ) 
       FIG. 34  shows another illustrative bottle container assembly  1700 , which may be similar to assembly  1500  of  FIGS. 28-32  but may enable a dial to interact with a groove on an exterior or outwardly facing surface of a closure. Assembly  1700  of  FIG. 34  may include one or more similar components to assembly  1500  of  FIGS. 28-32 , with components of assembly  1700  of  FIG. 34  being labeled with “17xx” reference labels that may correspond to the “15xx” reference labels of the labeled components of assembly  1500  of  FIGS. 28-32 , where differences therebetween may be described below. As shown, assembly  1700  may include a bottle  1790  and a cap  1710  that may be coupled to bottle  1790  for forming a closed container that may safely hold content therein.  FIG. 34  may show cap subassembly  1710  in a second or tensioned position, which may be similar to the position of cap subassembly  1510  of  FIG. 31 . Cap  1710  may include a closure  1720 , a dial  1730 , and a biasing mechanism  1781 . Closure  1720  of cap  1710  may include a closure body that may include one or more side walls  1725  that may extend from an at least partially closed top end  1721  to an at least partially open bottom end  1729  for defining an interior closure space  1723 . Rather than a portion of dial  1730  interacting with a groove on an interior surface of wall(s)  1725  of closure  1720 , one or more second internal side wall(s)  1725   i  may extend downwardly from top end  1721  internal to wall(s)  1725  (e.g., closer to but also about axis A) and at least one extender  1747   e  of dial  1730  may extend into a groove  1732  of closure  1720  that may be provided in an exterior surface of wall(s)  1725   i  about axis A. Therefore, rather than extending outwardly from the dial into an interior surface of the closure (e.g., as extender  1547   e  may extend outwardly away from dial  1530  and axis A into groove  1532  in an interior surface of closure  1520 ), extender  1747   e  may extend inwardly away from dial  1730  and towards axis A into groove  1732  in an exterior surface of closure  1720 . 
     FIG.  35  (Assembly  1800 ) 
       FIG. 35  shows another illustrative bottle container assembly  1800 , which may be similar to assembly  1500  of  FIGS. 28-32  but may include a biasing mechanism extending from the closure to a top of the dial. Assembly  1800  of  FIG. 35  may include one or more similar components to assembly  1500  of  FIGS. 28-32 , with components of assembly  1800  of  FIG. 35  being labeled with “18xx” reference labels that may correspond to the “15xx” reference labels of the labeled components of assembly  1500  of  FIGS. 28-32 , where differences therebetween may be described below. As shown, assembly  1800  may include a bottle (not shown) and a cap  1810  that may be coupled to the bottle for forming a closed container that may safely hold content therein. Cap  1810  may include a closure  1820 , a dial  1830 , and a biasing mechanism  1881 . Closure  1820  of cap  1810  may include a closure body that may include one or more side walls  1825  that may extend from an at least partially closed top end  1821  to an at least partially open bottom end  1829  for defining an interior closure space  1823 . Dial  1830  of cap  1810  may include a dial body that may include one or more side walls  1835  that may extend from an at least partially closed top end  1831  to an at least partially open or at least partially closed bottom end  1839 . Unlike assembly  1500 , assembly  1800  may be configured such that biasing mechanism  1881  may extend from an interior surface of top end  1821  of closure  1820  to an exterior surface of top end  1831  of dial  1830 . As shown, for example, biasing mechanism  1881  may include one or more springs or any other suitable mechanism features extending away from top end  1831  of dial  1830  towards top end  1821  of closure  1820  within closure space  1823 , such that biasing mechanism  1881  may be used in the same way as biasing mechanism  1581  of assembly  1500  but without requiring any portion of biasing mechanism  1881  from extending within dial  1830  (e.g., within a dial space between top end  1831  and bottom end  1839 ). An external force may be applied to any suitable external force interface of dial  1830  (e.g., for rotating dial  1830  within closure space  1823 ) in any suitable way, such as by a bottle  1890  or user U on bottom end  1839  and/or through a dial space and on to an interior surface of top end  1831 . 
     FIGS.  36 - 39  (Assembly  1900 ) 
       FIGS. 36-39  show another illustrative bottle container assembly  1900 , which may be similar to assembly  800  of  FIGS. 15-21  but may not include one or more features on a dial that move within a groove about the dial. Assembly  1900  of  FIGS. 36-39  may include one or more similar components to assembly  800  of  FIGS. 15-21 , with components of assembly  1900  of  FIGS. 36-39  being labeled with “19xx” reference labels that may correspond to the “8xx” reference labels of the labeled components of assembly  800  of  FIGS. 15-21 , where differences therebetween may be described below. As shown, assembly  1900  may include a bottle  1990  and a cap  1910  that may be coupled to bottle  1990  for forming a closed container that may safely hold content therein. For example, bottle  1990  may include a bottle body that may include one or more side walls  1995  that may extend from a closed bottom end (not shown) to an at least partially open top end  1991  for defining an interior bottle space  1993 . Bottle  1990  may be configured such that a user may insert content through open end  1991  into bottle space  1993  (e.g., along the −Z direction) and/or may remove content from bottle space  1993  through open end  1991  (e.g., along the ±Z direction) when cap subassembly  1910  is not coupled to bottle  1990 . Bottle  1990  may be any suitable container portion that may be configured to hold any suitable content in any suitable way. Bottle  1990  may be made of any suitable material or combination of materials and may be of any suitable dimensions. 
     Cap  1910  may be configured to be removably coupled to bottle  1990 , such that cap  1910  may cover open end  1991  for preventing a user from accessing bottle space  1993  when cap  1910  is coupled to bottle  1990 , and such that cap  1910  may not cover at least a portion of open end  1991  for enabling a user to access bottle space  1993  when cap  1910  is not coupled to bottle  1990 . Assembly  1900  may be configured in any suitable way for enabling cap subassembly  1910  to be removably coupled to bottle  1990 . As just one example, bottle  1990  may include at least one cap attachment feature  1992  and cap  1910  may include at least one bottle attachment feature  1928 , where cap attachment feature  1992  and bottle attachment feature  1928  may be any suitable combination of reciprocal or otherwise related features that may be configured to interact with each other for removably coupling cap  1910  to bottle  1990  (e.g., threads, snaps, notches, clips, location or transition fits, etc.). For example, cap  1910  may be screwed onto and off from bottle  1990  about an axis AB (e.g., in the direction of arrow R 1  or arrow R 2 ) using features  1928  and  1992 . Bottle  1990  may also include a lip  1994 , which may protrude from an exterior surface of body  1995  below cap attachment feature  1992 , where lip  1994  may be configured to suspend cap subassembly  1910  by at least a certain distance above the closed end. Cap attachment feature  1992  and/or lip  1994  may ensure a specific relationship between cap  1910  and bottle  1990  when cap  1910  is coupled to bottle  1990 . 
     Cap  1910  may include a closure  1920 , a dial  1930 , a dial enclosure  1944 , and a biasing mechanism  1981 . Dial enclosure  1944  of cap  1910  may include an enclosure body that may include one or more side walls  1945  that may extend from an at least partially open top end  1941  to an at least partially closed bottom end  1945  for defining an indicia space  1983  when coupled to closure  1920 . Closure  1920  of cap  1910  may include a closure body that may include one or more side walls  1925  that may extend from an at least partially closed top end  1921  to an at least partially open bottom end  1929  for defining an interior closure space  1923 . Closure  1920  may also include one or more closure indicia passageways  1926  through any suitable portions of closure  1920  for selectively exposing to a user one or more other portions of cap subassembly  1910  (e.g., portions of dial  1930 , as described below). As shown, closure indicia passageways  1926  may include at least one top closure indicia passageway  1926   t  that may be provided through the wall of top end  1921  of closure  1920 . Although not shown, closure indicia passageways  1926  may additionally or alternatively include at least one side closure indicia passageway that may be provided through at least one side wall  1925  of closure  1920 . Each closure indicia passageway  1926  may be a hollow opening through a wall or other portion of closure  1920  or may be such an opening that may be covered by or otherwise configured to include a transparent or translucent material or any other suitable object (e.g., a magnifying glass  1926   tm ) that may enable communication of information therethrough to a user of assembly  1900 . Closure  1920  may be made of any suitable material or combination of materials and may be of any suitable dimensions. As described below in more detail, closure  1920  may also include a dial access opening  1922  through any suitable portion of closure  1920 , such as through top end  1921  of closure  1920  as shown in  FIGS. 36-39 , which may enable a user U to access a portion of dial  1930  for manipulation thereof. Moreover, as shown in  FIGS. 36-39 , closure  1920  may include a content opening  1921   o  that may be provided through any suitable portion of closure  1920 , such as through top end  1921  of closure  1920 , and a content door  1921   d  that may be provided for selectively opening and closing content opening  1921   o . Closure  1920  may be configured such that a user U may insert content through content opening  1921   o  into bottle space  1993  (e.g., along the −Z direction) and/or may remove content from bottle space  1993  through content opening  1921   o  (e.g., along the +Z direction) when door  1921   d  is open and cap subassembly  1910  is not coupled to bottle  1990 . 
     Dial  1930  of cap  1910  may include a dial body that may include one or more side walls  1935  that may extend from an at least partially closed top end  1931  to an at least partially open bottom end  1939 . Dial  1930  may define an interior dial space  1933 , which may be accessible via a dial opening  1938 , which may be provided through any suitable portion of the dial body, such as through bottom end  1939 . Unlike assembly  800  in which a groove is provided in a portion of dial  830 , at least one groove  1932  may be provided along any suitable surface of dial enclosure  1944  of assembly  1900  rather than along a surface of dial  1930 , such as along an interior surface  1934  of one or more side walls  1925  of dial enclosure  1944  that may extend between an at least partially open top end  1941  and an at least partially closed bottom end  1949 , where groove  1932  may be accessible by a portion of dial  1530  within an indicia space  1983  (e.g., as defined between dial enclosure  1944  and a portion of closure  1920  when dial enclosure  1944  may be coupled to closure  1920 , as described below). Dial  1930  may include any suitable dial indicia  1936  that may be positioned on any suitable portions of dial  1930  for selective display to a user of assembly  1900 . As shown, dial indicia  1936  may include top dial indicia  1936   t  that may be provided on one or more exterior surface portions of top end  1931  of dial  1930 . Alternatively or additionally, although not shown in  FIGS. 36-39 , dial  1930  may include side dial indicia that may be provided on one or more exterior surface portions of one or more side walls of dial  1930  and/or bottom dial indicia that may be provided on one or more exterior surface portions of one or more bottom walls of dial  1930 . Dial  1930  may be configured to fit at least partially within indicia space  1983 , such that dial  1930  may be moved (e.g., rotated about axis A) within indicia space  1983  with respect to closure  1920  for selectively aligning different dial indicia  1936  of dial  1930  with a closure indicia passageway  1926  of closure  1920 . Dial  1930  may be made of any suitable material or combination of materials and may be of any suitable dimensions. Assembly  1900  may be configured in any suitable way for enabling dial enclosure  1944  to be removably or fixedly coupled to closure  1920 . As just one example, dial enclosure  1944  may include at least one closure attachment feature  1946  and closure  1920  may include at least one enclosure attachment feature  1922   b , where closure attachment feature  1946  and enclosure attachment feature  1922   b  may be any suitable combination of reciprocal or otherwise related features that may be configured to interact with each other for coupling enclosure  1944  to closure  1920  (e.g., threads, snaps, notches, clips, location or transition fits, etc.). For example, enclosure  1944  may be screwed onto and off from enclosure  1920  about an axis A (e.g., in the direction of arrow R 1  or arrow R 2 ) using features  1946  and  1922   b . When enclosure  1944  and enclosure  1920  are coupled together, side wall(s)  1945  and bottom end  1949  of enclosure  1944  and a portion of top end  1921  may define indicia space  1983 . Groove  1932  may be provided along an interior surface of side wall(s)  1945  of enclosure  1944  at least partially about axis A. 
     Rather than including a distinct button component, like button  844  of assembly  800 , certain features may be provided by dial  1930  for interacting with groove  1932  of enclosure  1944  for enabling rotation of dial  1930  with respect to closure  1920 . As shown, dial  1930  may include one or more closure interaction features  1947  that may be operative to interact with enclosure groove  1932  of enclosure  1944  for rotating dial  1930  within indicia space  1983 . Unlike assembly  800  in which button  844  may be pushed linearly in the Z-direction with respect to closure  820  but prevented from rotating with respect to closure  820 , the interaction of one or more enclosure interaction features  1947  of dial  1930  with enclosure groove  1932  of enclosure  1944  of assembly  1900  may enable dial  1930  not only to be pushed linearly in the Z-direction with respect to closure  1920  but also to be rotated with respect to closure  1920  within indicia space  1983 , such as, for example, between a first “high” position of  FIG. 37  and/or  FIG. 39  to a second “low” position of  FIG. 38 ). The interaction of at least one enclosure interaction feature  1947  with at least one enclosure groove  1932  may enable rotational movement of dial  1930  within indicia space  1983  (e.g., about axis A) with respect to closure  1920  after suitable linear movement of dial  1930  within indicia space  1983  (e.g., along the Z-axis) with respect to closure  1920 , for example, such that different indicia  1936  of dial  1930  may be rotated into alignment with a passageway  1926  of closure  1920 . As shown, groove  1932  may extend along an interior surface of enclosure  1944  about at least a portion of axis A, and, when dial  1930  is positioned within indicia space  1983 , at least a portion of each enclosure interaction feature  1947  may extend into at least a portion of enclosure groove  1932 . Each enclosure interaction feature  1947  may extend downwardly away from one or more portions of side wall  1935  away from bottom end  1939  (e.g., in the −Z-direction) to a bottom end  1947   t  of that enclosure interaction feature  1947 . At some location along the length of enclosure interaction feature  1947 , an extender portion  1947   e  may extend from the main body of interaction feature  1947  (e.g., outwardly away from axis A) for extending at least partially into groove  1932 . In some embodiments, end  1947   t  of an enclosure interaction feature  1947  may be a free end for enabling deflection of extender  1947   e  towards and/or away from axis A, for example, such that extender  1947   e  may be enabled to snap or otherwise fit into groove  1932 . In some embodiments, extender  1947   e  may extend away from the main body of interaction feature  1947  at end  1947   t . In other embodiments, extender  1947   e  may extend away from the main body of interaction feature  1947  at some point above end  1947   t , for example, such that end  1947   t  may be operative to interact with an interior surface of bottom  1949  of enclosure  1944 , which may at least partially limit the linear movement of dial  1930  in the −Z-direction within indicia space  1983 . 
     Biasing mechanism  1981  may be positioned at any suitable position within indicia space  1983  for biasing at least a portion of dial  1930  towards top end  1921  of closure  1920  (e.g., in the +Z-direction), for example, to at least partially control the linear movement of dial  1930  within indicia space  1983 . Biasing mechanism  1981  may be any suitable component or combination of components, such as any suitable spring, that may be operative to be compressed or tensioned for enabling movement of at least a portion of dial  1930  away from top end  1921  of closure  1920  (e.g., in the −Z-direction) when a suitable amount of force is applied to dial  1930  in that direction by an object remote from cap subassembly  1910  (e.g., a user U on a user feature  1931   u  that may extend upwardly away from top end  1931  (e.g., through opening  1922  of enclosure  1920 ) for providing an external force interface), while also being operative to decompress or relax for moving at least a portion of dial  1930  towards top end  1921  (e.g., in the +Z-direction) when such a suitable amount of force is not applied to dial  1930  by such a remote object. As shown, for example, biasing mechanism  1981  may include at least one spring that may be operative to be compressed from a first state (e.g., a first expanded or relaxed state of  FIG. 37  and/or  FIG. 39 , whereby biasing mechanism  1981  may have a first length B 1  along the Z-axis when no external force is applied to dial  1930 ) to a second state (e.g., a compressed or tensioned state of  FIG. 38 , whereby biasing mechanism  1981  may have a second length B 2  along the Z-axis that is shorter than length B 1 ) when a suitable external force is applied to dial  1930  in the −Z-direction (e.g., by user U, as described below in more detail) and that may be operative to expand from the second state to the first state when no such suitable external force is applied to dial  1930 . As shown, biasing mechanism  1981  may be positioned within indicia space  1983  for extending between an interior surface of top  1931  of dial  1930  and an interior surface of bottom  1949  of enclosure  1944  (e.g., along and/or about axis A). 
     Enclosure groove  1932  may extend along at least a portion of the interior of enclosure  1944  about at least a portion of axis A. Groove  1932  may have any suitable shape for translating movement of dial  1930  (e.g., extender  1947   e ) towards and/or away from top  1921  of closure  1920  (e.g., movement of dial  1930  along or substantially along the Z-axis) into rotation or other suitable movement of dial  1930  about axis A. For example, like groove  832  of assembly  800 , as shown, groove  1932  may include two or more vertical or substantially vertical segments  1932   v  (e.g., extending along or substantially along a Z-axis) and at least two diagonal segments  1932   d , where each diagonal segment  1932   d  may couple an upper portion  1932   u  of a first vertical segment  1932   v  to a lower portion  1932   l  of a second vertical segment  1932   v  that may be adjacent the first vertical segment  1932   v . Different stages of use of cap subassembly  1910  may be shown in  FIGS. 37-39  and may illustrate how the geometry of groove  1932  may at least partially dictate movement between such stages. 
     As shown in  FIG. 37 , cap subassembly  1910  may be in a first state, where no force external to cap subassembly  1910  may be applied to any portion of cap subassembly  1910 , such that such a first state of cap subassembly  1910  may be referred to as a relaxed state or an expanded state (e.g., as biasing mechanism  1981  may be in an expanded state of a first length B 1 , which may be limited from expanding to a greater length by one or more of a biasing characteristic or geometry of biasing mechanism  1981 , and/or the interaction of at least one extender  1947   e  of dial  1930  with a top of a respective vertical segment  1932   v  of groove  1932  of enclosure  1944  (e.g., at a lower portion  1932   l )). In such a first state of  FIG. 37 , a first particular side indicia (e.g., “Sun”) of top indicia  1936   t  may be aligned with top passageway  1926   t , while each extender  1947   e  of dial  1930  may be positioned within a respective vertical segment  1932   v  of groove  1932  of enclosure  1944  (e.g., at or proximal to the lower portion  1932   l  of that vertical segment  1932   v ). 
     Next, when any suitable external force is applied to cap subassembly  1910  that may be large enough to at least overcome the biasing force of biasing mechanism  1981  for reducing the vertical length B 1  of biasing mechanism  1981 , at least a portion of dial  1930  may be moved in the −Z-direction. For example, in some embodiments, as shown in  FIG. 38 , a user U may apply a user force in the −Z-direction onto any accessible portion of dial  1930  providing an external force interface (e.g., feature  1931   u ) that may reduce the vertical length of biasing mechanism  1981  to length B 2 . Such an external force may provide a second state of cap subassembly  1910  of  FIG. 38 . Such a second state of cap subassembly  1910  may be referred to as a compressed state or tensioned state, as biasing mechanism  1981  may be in a compressed or tensioned state of a second reduced length B 2 , which may be limited from compressing to an even shorter length by one or more of a biasing characteristic or geometry of biasing mechanism  1981 , the interaction of at least one extender  1947   e  of dial  1930  with a bottom of a respective vertical segment  1932   v  of groove  1932  of enclosure  1944  (e.g., at an upper portion  1932   u ), and/or the interaction of top  1947   t  of dial  1930  with a portion of enclosure  1944  (e.g., an interior surface of bottom  1949 ). In such a second state of  FIG. 38 , the first particular side indicia (e.g., “Sun”) of top indicia  1936   t  may remain aligned with top passageway  1926   t . Moreover, in such a second state of  FIG. 38 , each extender  1947   e  of dial  1930  may remain positioned within the same respective vertical segment  1932   v  of groove  1932  of enclosure  1944  as it was at the first state of  FIG. 37 , but at a location within that vertical segment  1932   v  that is at or proximal to the upper portion  1932   u  of that vertical segment  1932   v.    
     As shown in  FIG. 39 , cap subassembly  1910  may advance to a third state when the external force being applied to cap subassembly  1910  in its second state of  FIG. 38  is terminated or reduced a suitable amount. For example, when the external force applied by user U is at least partially reduced or removed such that bias mechanism  1981  forces each extender  1947   e  of dial  1930  in an upward direction (e.g., in the +Z-direction), the geometry of groove  1932  and its interaction with extender  1947   e  may be operative to prevent extender  1947   e  from traveling back up the same initial vertical segment  1932   v  in which extender  1947   e  was located in its second state of  FIG. 38  (e.g., in the +Z-direction) but rather may be operative to guide the travel of extender  1947   e  diagonally upwardly along the diagonal segment  1932   d  extending from the upper portion  1932   u  of the initial vertical segment  1932   v  of the first and second states and into the lower portion  1932   l  of an adjacent new vertical segment  1932   v  for the third state of cap subassembly  1910 . Such diagonal movement of extender  1947   e  with respect to closure  1920  along groove  1932  may rotate dial  1930  about axis A from its rotational orientation of the second state of  FIG. 38  to its rotational orientation of the third state of  FIG. 39  (e.g., by an arc length equal to the arc length between the two adjacent vertical segments  1932   v ). In such a third state of  FIG. 39 , a new particular side indicia (e.g., “Mon”) of top indicia  1936   t  may now be aligned with top passageway  1926   t  (e.g., as compared to “Sun” of the first state of  FIG. 37 ), as each extender  1947   e  of dial  1930  may be positioned within a new respective vertical segment  1932   v  of groove  1932  of enclosure  1944  (e.g., at or proximal to the lower portion  1932   l  of that new vertical segment  1932   v ). Such a third state of cap subassembly  1910  of  FIG. 39  may also be referred to as a relaxed state or an expanded state (e.g., as biasing mechanism  1981  may be in an expanded state of first length B 1 , which may be limited from expanding to a greater length by one or more of a biasing characteristic or geometry of biasing mechanism  1981 , and/or the interaction of at least one extender  1947   e  of dial  1930  with a top of the new respective vertical segment  1932   v  of groove  1932  of enclosure  1944 ). Therefore, the interaction between the geometry of upwardly moving extender  1947   e  of dial  1930  and the geometry of groove  1932  of enclosure  1944  may rotate dial  1930  about axis A for aligning new indicia with one or more passageways for viewing by a user of cap subassembly  1910 . Although not shown in  FIGS. 36-39 , groove  1932  of enclosure  1944  of assembly  1910  may be provided with the same depth variation as described above with respect to assembly  800  and  FIGS. 20 and 21 . Alternatively, in other embodiments, although not shown, dial  1930  may be prevented from moving linearly with respect to closure  1920  (e.g., along axis Z) but may only be enabled to rotate with respect to closure  1920  (e.g., about axis A), while enclosure  1944  may be coupled to closure  1920  in such a manner that enclosure  1944  may be enabled to move linearly with respect to closure  1920  (e.g., along axis Z) but may be prevented from rotating with respect to closure  1920  (e.g., about axis A), such that rather than a user U applying a downward force on feature  1931   u  of dial  1930  for moving subassembly  1910  from its first position to its second position for enabling rotation of dial  1930 , a user U may apply an upward force on an exterior surface of bottom end  1949  of enclosure  1944  providing an external force interface for moving subassembly  1910  from its first position to its second position for enabling rotation of dial  1930 . Although not shown, a rubber or any other suitable material (e.g., pacifier like covering (e.g., cover  269  of  FIG. 7 )) may provide a protection layer along an exterior surface of a bottom layer of one or more portions of a cap assembly, which may protect the cap assembly from being exposed to any content of the bottle (e.g., a liquid substance). In some embodiments, a biasing mechanism may not be provided and gravity, for example, may be operative to move a cap assembly from a second position to a third position once an external force is no longer applied to the cap assembly (e.g., by a user or a coupled bottle).

       FIG. 40  is a flowchart of an illustrative process  2000  for changing the portion of indicia on a dial within a bottle cap that is visible to a user through a passageway in the bottle cap. At step  2002 , process  2000  may include pushing a user gear along a first axis towards a dial gear that is coupled to the dial. For example, as described with respect to any one of assemblies  100 - 700 , a user gear  162 - 762  may be pushed towards a dial gear  152 - 752  that is coupled to a dial  130 - 730  for eliminating a spacing distance (e.g., distance  141 ) between the two gears. Next, at step  2004 , during the pushing of step  2002 , process  2000  may include rotating the user gear about the first axis. For example, as described with respect to any one of assemblies  100 - 700 , a user gear  162 - 762  may be rotated when such a spacing distance has been eliminated (e.g., when teeth of the user gear are meshed with teeth of the dial gear). Then, at step  2006 , process  2000  may include rotating the dial gear and the dial about a second axis using the rotation of the user gear. For example, as described with respect to any one of assemblies  100 - 700 , rotation of a user gear  162 - 762  may rotate a dial gear  152 - 752  and a dial  130 - 730  coupled thereto. In some embodiments, the first axis of the pushing of step  2002  and of the rotating of step  2004  may be the same as the second axis of the rotating of step  2006  (e.g., axis A of assembly  700  of  FIGS. 13 and 14 ). In other embodiments, the first axis of the pushing of step  2002  and of the rotating of step  2004  may be different than the second axis of the rotating of step  2006  (e.g., axis B versus axis A of any one of assemblies  100 - 600  of  FIGS. 1-12 ). 
     It is understood that the steps shown in process  2000  of  FIG. 40  are merely illustrative and that existing steps may be modified or omitted, additional steps may be added, and the order of certain steps may be altered. 
     FIG.  41  (Process  2100 ) 
       FIG. 41  is a flowchart of an illustrative process  2100  for changing the portion of indicia on a dial within a closure of a bottle cap that is visible to a user through a passageway in the closure. The bottle cap may include the closure, the dial, a path component that defines a path, an interaction feature, and an external force interface coupled to the interaction feature. At step  2102 , process  2100  may include moving the interaction feature along a first segment of the path that extends in a first direction that is parallel to a particular axis when an external force is applied to the external force interface. Next, at step  2104 , process  2100  may include moving the interaction feature along a second segment of the path that extends from the first segment about at least a portion of the axis when the external force is at least partially terminated on the external force interface. For example, as described with respect to any one of the assemblies  800 - 1400  of  FIGS. 15-27 , a surface of a dial may define a groove or other suitable path (e.g., groove  832  of dial  830 ), and a push button may include an external force interface and an interaction feature (e.g., bottom end  849  and extender portion  847   e  of interaction feature  847  of button  840 ). In other embodiments, as described with respect to any one of the assemblies  1500 - 1900  of  FIGS. 28-39 , a surface of a closure may define a groove or other suitable path (e.g., groove  1532  of closure  1520 ), and a dial may include an external force interface and an interaction feature (e.g., bottom end  1539  and extender portion  1547   e  of interaction feature  1547  of dial  1530 ). In any event, when an external force is applied to such an external force interface (e.g., by a user U or by a portion of a container coupled to the cap, such an interaction feature may be moved along a first segment of the path (e.g., a vertical segment) that may extend in a first direction that is parallel to a particular axis (e.g., vertical segment  832   v  may extend from lower portion  832   l  to upper portion  832   u  in a direction parallel to axis A), and when such an external force is at least partially terminated (e.g., when gravity or the expansion force of a biasing mechanism is greater than any external force applied to the external force interface), such an interaction feature may be moved along a second segment of the path (e.g., a diagonal segment) that extends from the first segment about at least a portion of the particular axis (e.g., diagonal segment  832   d  may extend from upper portion  832   u  of vertical segment  832   v  about a portion of axis A) for rotating a dial within a closure space. 
     It is understood that the steps shown in process  2100  of  FIG. 41  are merely illustrative and that existing steps may be modified or omitted, additional steps may be added, and the order of certain steps may be altered. 
     FURTHER APPLICATIONS OF DESCRIBED CONCEPTS 
     While there have been described adjustable indicators for containers and methods for using and making the same, it is to be understood that many changes may be made therein without departing from the spirit and scope of the subject matter described herein in any way. Insubstantial changes from the claimed subject matter as viewed by a person with ordinary skill in the art, now known or later devised, are expressly contemplated as being equivalently within the scope of the claims. Therefore, obvious substitutions now or later known to one with ordinary skill in the art are defined to be within the scope of the defined elements. It is also to be understood that various directional and orientational terms, such as “proximal” and “distal,” “up” and “down,” “front” and “back,” “upper” and “lower,” “top” and “bottom” and “side,” “vertical” and “horizontal” and “diagonal,” “length” and “width” and “thickness” and “diameter” and “cross-section” and “longitudinal,” “X-” and “Y-” and “Z-,” and the like, may be used herein only for convenience, and that no fixed or absolute directional or orientational limitations are intended by the use of these words. For example, the assemblies and patients can have any desired orientations. If reoriented, different directional or orientational terms may need to be used in their description, but that will not alter their fundamental nature as within the scope and spirit of the subject matter described herein in any way. 
     Therefore, those skilled in the art will appreciate that the invention can be practiced by other than the described embodiments, which are presented for purposes of illustration rather than of limitation.
