Description:
CROSS REFERENCE TO RELATED APPLICATIONS 
     This application claims the benefit of U.S. Provisional Application No. 62/868,709, filed Jun. 28, 2019, which is hereby incorporated by reference herein in its entirety. 
    
    
     TECHNICAL FIELD 
     The disclosed subject matter relates to reclosable can ends. 
     BACKGROUND 
     Cans are frequently used for storing and drinking such beverages as soda, beer, water, Ready To Drink (RTD) beverages and cocktails, energy drinks, juices, sparkling water and many more beverages and liquids, and/or for other cannable storage needs. Cans, which are often made from aluminum and aluminum alloy, are convenient for storing and drinking for many reasons. For example, aluminum is lightweight, is easily transportable, saves space in shipping containers, is sturdy, and is 100% recyclable. However, once a can is opened, it is typically not used as a portable container. In particular, cans are typically not reclosable, and it can therefore be difficult to transport an opened can and to keep a beverage in an opened can free from dirt, debris, or bugs. 
     Accordingly, it is desirable to provide a reclosable can end. 
     SUMMARY 
     A reclosable can end is provided. 
     In accordance with some embodiments, of the disclosed subject matter, a reclosable can end is provided, the reclosable can end comprising: a lid base positioned at a top portion of the reclosable can end, wherein the lid base comprises a scored area; a tab, wherein a first end of the tab is configured to apply pressure to the scored area of the lid base when a second end of the tab, opposite the first end of the tab, is lifted and causes the scored area to at least partially separate from the lid base to expose an opening in the lid base; a closure flap, wherein the closure flap comprises: a first portion that has dimensions corresponding to dimensions of the opening in the lid base opening wherein the first portion of the closure flap includes a raised bump that connects with a portion of the tab; a second portion that comprises an outer edge that extends beyond the first portion of the closure flap; an opening; and a protruding portion that protrudes from the outer edge of the second portion of the closure flap; and a rivet that connects the tab and the closure flap to the lid base such that the tab and the closure flap are configured to rotate around the rivet, wherein the rivet connects the tab and the closure flap to the lid base via the opening in the closure flap, wherein the first portion of the closure flap is configured to be inserted into the opening in the lid base end when the tab and the closure flap are rotated to a position corresponding to a position of the opening in the lid base, wherein the outer edge of the second portion of the closure flap is positioned on the top portion of the lid base when the first portion of the closure flap is inserted into the opening in the lid base, and wherein an edge that connects the first portion of the closure flap to the outer edge of the second portion of the closure flap includes an angled portion that connects to an indented portion such that the indented portion is positioned on a bottom portion of the lid base opening edge when the first portion of the closure flap is inserted into the opening of the lid base.

     DETAILED DESCRIPTION 
     In accordance with various embodiments, reclosable can ends are provided. 
     In some embodiments, reclosable can ends are described herein. In some embodiments, a reclosable can end can be part of any suitable type of can, such as a soda can, that can be used to store any suitable type of liquid or beverage, or a can that can be used for any other suitable cannable storage needs. 
     In some embodiments, a can that includes a reclosable can end can be opened. For example, in some embodiments, a lid base of the can end (e.g., a flat top portion of the can end) can be opened such that a scored flap of the lid base is pressed inward to expose an opening in the lid base. In some embodiments, a scored flap can be pressed inward in any suitable manner, such as by using a tab attached to the lid base that can act as a lever to apply pressure to the scored portion, thereby breaking a perforated border of the scored flap and lid base. 
     In some embodiments, the tab can be coupled to a closure flap that has a size and dimensions corresponding to an opening in the lid base such that the closure flap can be turned and then pressed into the opening to close the opening in the lid base, thereby providing a seal in the opening in the lid base. In some embodiments, the closure flap can be pulled and/or rotated out of the opening to open the lid base. Continuing further, in some embodiments, the closure flap can be reinserted in the lid base to reclose the opening in the lid base. In some embodiments, the closure flap can be inserted and rotated from an opening of an opened can any suitable number of times while still maintaining a seal over the opening. 
     In some embodiments, a tab can be coupled to a closure flap and attached to a lid base of a can end in any suitable manner. For example, in some embodiments, a tab can be coupled to a closure flap and attached to a lid base via a rivet made from a raised center area of the lid base, as shown in and described below in connection with  FIGS.  10 A,  10 B, and  10 C . As another example, in some embodiments, a tab can be coupled to a closure flap and attached to a lid base via a rivet made from a raised center area of the tab, such as shown in and described below in connection with  FIG.  3 E . As yet another example, in some embodiments, a tab can be coupled to a closure flap and attached to a lid base via an independent rivet, such as shown in and described below in connection with  FIGS.  4 A,  4 B, and  4 C . In some embodiments, any suitable mechanism can be used to couple a tab to a closure flap and to attach the coupled tab and closure flap to a lid base, which can allow the tab and the closure flap to lock and rotate together. 
     Note that, in some embodiments, “can end” can refer to a top portion of a can. In some embodiments, a can end can include any suitable elements, such as a lid base (e.g., a flat portion of a can end with shaped edges to allow the can end to attach to a can body), a scored flap corresponding to an opening in the lid base when the can has been opened, a closure flap, a tab, and/or any suitable rivets. Additionally, note that, in some embodiments, lid bases, closure flaps, tabs, and rivets as described herein can be manufactured for can ends of any suitable size. 
     In some embodiments, a closure flap, tab, and any rivets can remain attached to a can, thereby reducing litter and protecting consumers and animals from abrasions due to any sharp and/or metal edges. Additionally, in some embodiments, any suitable portions of a closure flap, tab, rivets, lid base, and/or any other suitable elements of a can end can be made from any suitable materials (e.g., aluminum and/or aluminum alloy as used in a can body), thereby allowing the closure flap, tab, rivets, and/or lid base to be recycled. 
     Turning to  FIGS.  1 A and  1 B , top views of examples of reclosable can ends are shown in accordance with some embodiments of the disclosed subject matter.  FIG.  1 A  shows an example of a lid base  100  that has not yet been opened. Note that, in some embodiments, a can end can be made of any suitable material, such as aluminum, an aluminum alloy, steel, and/or any other suitable materials. Additionally, note that, in some embodiments, a body of a can can be made of a different material than a can end. In some embodiments, an internal portion of a can end can be coated with any suitable material or combination of materials. For example, in some embodiments, an internal portion of the can end can be coated with epoxy resin. As another example, in some embodiments, an internal portion of the can end can be coated with a polymer plastic lining that is made of any suitable material or combination of materials (e.g., polyethylene, polypropylene, polyester, styrene, acrylic, vinyl, and/or any other suitable material(s)). 
     As illustrated,  FIG.  1 A  includes a tab  102 , a closure flap  108 , a tab rivet area  110 , lid base  100 , and a scored flap  104 . Note that, as shown in  FIG.  1 A , scored flap  104  is fully attached to lid base  100 , because tab  102  has not yet caused scored flap  104  to separate from a top portion of lid base  100 . In some embodiments, tab  102  can be connected to any suitable portion of lid base  100  (e.g., a center portion, and/or any other suitable portion) in any suitable manner. For example, in some embodiments, tab  102  can be connected to lid base  100  via a rivet in tab rivet area  110 . Note that, in some such embodiments, a rivet in tab rivet area  110  can be a rivet that is part of lid base  100  (e.g., as shown in and described below in connection with  FIGS.  10 A,  10 B , and/or  10 C), a rivet that is part of tab  102  in tab rivet area  110  (e.g., as shown in and described below in connection with  FIG.  3 E ), and/or an independent rivet inserted in tab rivet area  110  (e.g., as shown in and described below in connection with  FIGS.  4 A,  4 B, and  4 C ). 
     In some embodiments, tab  102  can cause a portion of scored flap  104  to at least partially separate from lid base  100 , thereby opening lid base  100 , as illustrated in  FIG.  1 B . In some embodiments, opening lid base  100  can cause an opening  106  of lid base  100  to be exposed. In some embodiments, tab  102  can cause the portion of scored flap  104  to separate from lid base  100  in any suitable manner. For example, in some embodiments, a tip of tab  102  that is above scored flap  104  can be pressed into scored flap  104 , thereby causing a portion of scored flap  104  to be pressed into an interior of a can body attached to lid base  100 . In some embodiments, the tip of tab  102  can be pressed into scored flap  104  in any suitable manner. For example, in some embodiments, tab  102  can be operated as a second class lever and a first class lever around a corresponding to tab rivet area  110  by lifting a back end of tab  102  that is opposite the tip of tab  102 , thereby causing the tip of tab  102  to apply pressure to scored flap  104 . 
     As shown in  FIG.  1 B , in some embodiments, tab  102  can be connected to a closure flap  108  in any suitable manner including a rivet, welding, recyclable sealant, rubber, recyclable glue, links, and/or in any other suitable manner. For example, in some embodiments, tab  102  can be connected to closure flap  108  via a rivet corresponding to tab rivet area  110 . Note that, in some embodiments, the rivet corresponding to tab rivet area  110  can be part of lid base  100  (e.g., as shown in and described below in connection with  FIG.  10 A ), part of tab  102  (e.g., as shown in and described below in connection with  FIG.  3 E ), and/or an independent rivet (e.g., as shown in and described below in connection with  FIGS.  4 A,  4 B, and  4 C ). 
     As shown in  FIG.  1 B , in some embodiments, closure flap  108  can have a size and a shape that corresponds to opening  106 , thereby allowing closure flap  108  to be inserted into opening  106  to re-close and seal lid base  100  after scored flap  104  of lid base  100  has been opened. 
     Note that, as shown in  FIG.  1 B , tab  102  can be joined by a rivet corresponding to tab rivet area  110 , thereby allow tab  102  to rotate in conjunction with closure flap  108 , either clockwise or counterclockwise. For example, in some embodiments, closure flap  108  can be rotated to a position suitable for insertion of closure flap  108  into opening  106  to seal opening  106 . 
     Additionally, note that, in some embodiments, scored flap  104  can have any suitable size and/or any suitable shape depressions. In some embodiments, scored flap  104  can be scored or perforated to allow a portion of scored flap  104  to separate from lid base  100  when a tip of tab  102  is depressed on scored flap  104  to open lid base  100 . Note that, when opened, in some embodiments, scored flap  104  can remain attached to lid base  100  via a link  112 . In some embodiments, any suitable portion of scored flap  104 , link  112 , and/or lid base  100  can be scored or perforated to allow any portion of scored flap  104  to bend from lid base  100  when lid base  100  is opened to allow the portion of scored flap  104  to remain attached to lid base  100  while providing a seal between closure flap  108  and opening  106 . 
     In some embodiments, scored flap  104  can be scored in multiple ways around a circumference of opening  106  and at link  112 . In some embodiments, scored flap  104 , where it meets link  112 , can curl upward and inward toward the center of lid base  100 , such as shown in and described below in connection with  FIG.  5 C . As another example, in some embodiments, scored flap  104 , where it meets link  112 , can be scored such that it is a dead end stop with no curl as shown in and described below in connection with  FIG.  5 A . As yet another example, in some embodiments, scored flap  104 , where it meets link  112 , can be scored such that it can curl down and inward toward the center of scored flap  104  as shown in and described below in connection with  FIG.  5 D . 
     In some embodiments, an underside of link  112  can be perforated in any suitable manner (e.g., as shown in and described below in connection with  FIG.  5 B ) to create a more desirable angle to provide a seal of closure flap  108  over opening  106  of lid base  100  and link  112 . For example, in some embodiments, the underside of link  112  adjacent to a point at which link  112  connects to lid base  100  when lid base  100  is open can have small cuts or indents such that scored flap  104  bends around the perforations of link  112  when lid base  100  is open. In some embodiments, a depth of the perforations of the underside of link  112  can be deep enough to allow scored flap  104  to bend straight inward into opening  106  and around link  112  area but shallow enough that link  112  remains connected to lid base  100  when lid base  100  is opened. 
     Turning to  FIG.  2 A , an example of lid base  100  without a tab and when lid base  100  has not yet been opened (that is, scored flap  104  has not been pressed down) is shown in accordance with some embodiments of the disclosed subject matter. Note that, as shown in  FIG.  2 A , closure flap  108  can be positioned in a portion (e.g., a recessed portion, and/or any other suitable portion) of lid base  100  when closure flap  108  is not in use. 
     Turning to  FIG.  2 B , an example of lid base  100  without a tab and without a closure flap, when lid base  100  has not yet been opened is shown in accordance with some embodiments of the disclosed subject matter. 
     Note that, in some embodiments, a lid base  100  can include a drip-catch  208  (e.g., that catches liquid that comes out of an opening of lid base  100  when open), a lid base pocket  210 , a lid base rivet area  204 , and a rim  212 . 
     In some embodiments, drip-catch  208  of lid base  100  can have any suitable lid base pocket  210  with any type of depression, angle, edges, shape, arch, depth and width. In some embodiments, lid base pocket  210  can be used as a holding area for closure flap before lid base  100  is opened or when lid base  100  is re-opened. In some embodiments, lid base pocket  210  can be under a closure flap and can then be exposed once the closure flap is turned. 
     In some embodiments, drip-catch  208  can have a width or depth that is wide enough or deep enough to accommodate an opening of lid base  100  or a closure flap. As a more particular example, in an instance in which an opening of lid base  100  is wider than an opening of a traditional soda can, drip-catch  208  of lid base  100  can be relatively wider and more oval than a drip-catch of a traditional can end. In some embodiments, drip-catch  208  can include padding of any suitable type of material. 
     Referring to  FIGS.  2 A and  2 B , shapes of rivet areas of a closure flap (e.g., closure flap  108  as shown in  FIG.  2 A ) and a lid base (e.g., lid base  100  as shown in  FIG.  2 B ) are shown in accordance with some embodiments of the disclosed subject matter. For example, referring to  FIG.  2 A , in some embodiments, any suitable rivet can be inserted in a closure flap rivet area  202  to couple closure flap  108  to a tab (not shown). Note that, in some embodiments, a rivet inserted in closure flap rivet area  202  can be any suitable rivet, such as a rivet that is part of the tab (e.g., as shown in and described below in connection with  FIG.  3 E ), a rivet that is part of a lid base (e.g., as shown in and described below in connection with  FIG.  10   ), and/or an independent rivet (e.g., as shown in and described below in connection with  FIGS.  4 A,  4 B, and  4 C ). Additionally, note that, although closure flap rivet area  202  is shown as triangular in shape, in some embodiments, closure flap rivet area  202  can have any suitable shape (e.g., square, round, hexagonal, and/or any other suitable shape). 
     As another example, referring to  FIG.  2 B , in some embodiments, any suitable rivet can be used in lid base rivet area  204  to connect lid base  100  to a tab and closure flap. Note that, in some embodiments, the rivet can be a rivet that is part of the lid base (e.g., as shown in and described below in connection with  FIGS.  10 A,  10 B , and/or  10 C) that is located at lid base rivet area  204  on lid base  100 , a rivet that is part of the tab (e.g., as shown in and described below in connection with  FIG.  3 E ) that is inserted through the closure flap and through lid base rivet area  204 , and/or an independent rivet (e.g., as shown in and described below in connection with  FIGS.  4 A,  4 B, and  4 C ). Additionally, note that, although lid base rivet area  204  is shown as circular in shape, in some embodiments, lid base rivet area  204  can be any suitable shape (e.g., square, triangular, hexagonal, and/or any other suitable shape). In some embodiments, lid base rivet area  204  can be smaller or larger than closure flap rivet area  202 . 
     Note that, although tab  102 , closure flap  108 , and lid base  100  are shown in and described above in connection with  FIGS.  1 A,  1 B,  2 A, and  2 B , in some embodiments, any suitable alternative designs of tabs, closure flaps, lid bases, and rivets can be used in any suitable combination. For example, in some embodiments, alternative tab designs (e.g., as shown in and described below in connection with  FIG.  3 A,  3 B,  3 C,  3 D,  3 E,  9 A , and/or  9 F), alternative closure flap designs (e.g., as shown in and described below in connection with  FIG.  6 A,  6 B,  6 C,  7 A,  7 B,  7 C,  8 ,  9 A,  9 B,  9 C,  9 D , and/or  11 ), alternative rivet designs (e.g., as shown in and described below in connection with  FIGS.  4 A,  4 B,  4 C,  9 A,  9 B,  9 C,  9 D,  9 E,  9 F,  9 G,  10 A,  10 B , and/or  10 C), and/or alternative lid base designs (e.g., as shown in and described below in connection with  FIGS.  10 A,  10 B,  10 C , and/or  11 ) can be used in any suitable combination. 
     Turning to  FIG.  3 A , a top view of tab  102  is shown in accordance with some embodiments of the disclosed subject matter. Note that tab  102  is shown in  FIG.  3 A  with a tab rivet area  301  that is triangular in shape. In some embodiments, a tab can have a rivet area with any suitable shape (e.g., circular, triangular, square, L-shaped, hexagonal, and/or any other suitable shape). For example, as shown in  FIG.  3 C , a tab can have a round tab rivet area  312 . 
     Turning to  FIG.  3 B , an angled side view of a tab  102  is shown in accordance with some embodiments of the disclosed subject matter. In some embodiments, a force part  302  of tab  102  (e.g., a back portion of a tab) can have an arched or concave shape that allows tab  102  to be pulled upward by a finger and to be rotated. Additionally, note that tab  102  can have any suitable shape or dimensions that differ from tabs used in other drink cans. For example, in some embodiments, tab  102  can have a thicker force part  302  and/or thicker side portions  304  and/or  306  relative to tabs used in other drink cans. As another example, in some embodiments, a length and/or a width of tab  102  from force part  302  to tab rivet area  301  can be different in shape than tabs used in other drink cans (e.g., longer, shorter, wider, thinner, and/or different in any other suitable manner). 
     In some embodiments, a tab, a closure flap, and a lid base can be coupled using an independent rivet (e.g., a rivet that is not a part of any of the tab, the closure flap, and/or the lid base).  FIGS.  4 A,  4 B, and  4 C  show examples of independent rivets that can be used to couple any of a tab, a closure flap, and/or a lid base. 
     Turning to  FIG.  4 A , example views of an independent rivet with a circular top portion are shown in accordance with some embodiments of the disclosed subject matter. View  400  shows a three-dimensional side view of a rivet. As illustrated, the rivet includes a circular top portion  402 , a triangular middle portion  404 , and a circular bottom portion  406 . In some embodiments, circular top portion  402  can overlap a tab and can lock into a tab rivet area and a closure flap rivet area, thereby holding both the tab and the closure flap to a lid base. In some embodiments, triangular middle portion  404  can act as a lock between the closure flap and the tab, thereby allowing the tab and the closure flap to rotate as one piece. In some embodiments, circular bottom portion  406  can go through lid base rivet area  204  (as shown in and described above in connection with  FIG.  2 B ) of lid base  100  thereby allowing the tab and the closure flap to rotate together. In some embodiments, circular bottom portion  406  can be flattened by machinery to secure the rivet, as shown in and described below in connection with  FIG.  9 G . 
       FIG.  4 A  additionally shows a top view  408  and a bottom view  410  of the rivet shown in view  400 . Note that, as shown in  FIG.  4 A , in some embodiments, circular top portion  402  can have the largest area of the three portions of the rivet, and circular bottom portion  406  can have the smallest area of the three portions of the rivet. Note that, in some embodiments, each section of a rivet can vary in height, width, length, circumference, and/or in any other suitable manner. 
     Turning to  FIG.  4 B , an example  412  of a rivet with a triangular top portion  414  is shown in accordance with some embodiments of the disclosed subject matter. 
     Turning to  FIG.  4 C , an example  416  of a rivet with a round top and a cylindrical body  418  is shown in accordance with some embodiments of the disclosed subject matter. 
     In some embodiments, shapes of holes of a closure flap can correspond to portions of a rivet. For example, in some embodiments, rivet  416  (as shown in and described above in connection  FIG.  4 C ) can connect a tab with a circular tab rivet area to a closure flap with a circular closure flap rivet area. In some embodiments, this can allow the rivet and the closure flap to turn either clockwise or counter-clockwise. 
     It should be noted that the illustrated relative dimensions may differ from an actual rivet implemented in accordance with some embodiments. For example, in some embodiments, the height of each portion of  402 ,  404 ,  406 , and  418  may be shorter than a width and/or a diameter of that portion. In some embodiments, the heights may be exaggerated herein for clarity. 
     Turning to  FIG.  5 A , an example top view of a scored flap of a lid base (e.g., such as scored flap  104  as shown in and described above in connection with  FIG.  1 B ) is shown in accordance with some embodiments of the disclosed subject matter.  FIG.  5 B  shows an example bottom view of the scored flap with perforations on the lid base.  FIG.  5 C  shows an example top view of an alternate curved up scored area  502  where it meets link  112 .  FIG.  5 D  shows an example top view of an alternate curved down scored area  504  where it meets link  112 . Note that, in some embodiments, any suitable scored flap can be used in connection with any lid base. 
     In some embodiments, a closure flap can include any suitable elements that can allow a tab to exert pressure on a closure flap when a closure flap is inserted into an opening of a can to allow a more unified and/or tighter seal to be formed between the closure flap and the opening of the can. Additionally, a closure flap can include any suitable elements that allow a tab to rotate a connected closure flap.  FIGS.  6 A,  6 B, and  6 C  show examples of closure flaps with various design elements. Note that, in some embodiments, any of the elements shown in  FIGS.  6 A,  6 B , and/or  6 C can be combined in any suitable manner in a closure flap. 
     As shown in  FIGS.  6 A,  6 B, and  6 C , in some embodiments, a closure flap can have one or more variously shaped bumps, molds, raises, flaps, lips, or other designs. In some embodiments, a bump on a closure flap can aid a lock between a tab and the closure flap, aid in pushing and pulling the connected tab and closure flap, allow a tab to exert even pressure on a closure flap when the closure flap is inserted into an opening of a lid base, and/or perform any other suitable functions. In some embodiments, a closure flap can include any suitable bumps, such as bump  602  and/or bump  604  as shown in  FIG.  6 A , bump  610  and/or bump  614  as shown in  FIGS.  6 A and  6 C , and/or any other suitable bumps. In some embodiments, the one or more bumps can correspond to raised portions of an interior of the closure flap. Note, that, in some embodiments, a closure flap can include any suitable number of bumps (e.g., zero, one, two, three, five, and/or any other suitable number), each located at any suitable position on the closure flap. In some embodiments, the one or more bumps on a closure flap can be generated in any suitable manner, for example, by using any suitable welding or molding technique (e.g., using injection molding and/or any other suitable molding, welding, or shaping technique). 
     In some embodiments, the one or more bumps can meet a bottom portion of a tab, which can cause the tab to exert even pressure on the closure flap when the closure flap is inserted into an opening of an open can, thereby allowing a more unified and/or tighter seal to be formed between the closure flap and an opening of the can. In addition, the one or more bumps can act and engage as a lock with a tab to assist in rotation of the closure flap over an opening of the can end. Note that examples of closure flaps with one or more bumps that meet a bottom portion of a tab are shown in and described below in more detail in connection with  FIGS.  7 A,  7 B, and  7 C . Turning to  FIG.  3 C , in some embodiments, a square shaped bump (e.g., bump  614  of  FIGS.  6 A and  6 C ) can fit into a square shaped tab opening  314  of a tab  310 . As another example, in some embodiments, a round shaped bump (e.g., bump  610  of  FIG.  6 A ) can fit into a round shaped tab opening  318  of tab  310 . Note that, in some embodiments, each bump on a closure flap can have any suitable shape (e.g., round, square, rectangular, L-shaped, U-shaped, triangular, hexagonal, and/or any other suitable shape). Additionally, note that, in some embodiments, a tab can have openings of any suitable shape(s) that correspond to bumps of a closure flap that is to be connected to the tab. 
     Referring back to  FIG.  6 A , top views of an alternate closure flap  114  are shown in accordance with some embodiments of the disclosed subject matter. In some embodiments, closure flap  114  can include one or more closure flap lips  612  (as shown in  FIGS.  6 A and  6 C ). In some embodiments, closure flap lips  612  can act as a lock or a hook that engages with lips on a tab. For example, turning to  FIGS.  3 C and  3 D , tab  310  can include tab lips  316 . In some embodiments, as a tab turns, closure flap lips  612  can act as pressure points against tab lips  316 . In some embodiments, when the tab turns, both closure flap lips  612  and tab lips  316  can aid in the rotation (e.g., pushing or pulling a connected tab and closure flap), clockwise or counter-clockwise, and locking of the tab to closure flap  114  while still allowing the tab to rotate. Note that, referring to  FIG.  3 D , in some embodiments, a tab can additionally include pressure points  320 . In some embodiments, when pressure is applied to pressure points  320 , the tab can engage with a connected closure flap to create a secure seal of the closure flap in an opening of a lid base. In some embodiments, pressure points  320  can be any suitable added material, bumps, and/or punctures. In some embodiments, pressure points  320  can be formed from any part of a mold and/or in any other suitable manner. Note that  FIG.  3 D  shows an underside of tab  310 . 
     Referring back to  FIG.  6 A , in some embodiments, a closure flap can have an outer edge  609  that acts as an edge, lip, glide, flap, ledge, or seal. In some embodiments, outer edge  609  can extend beyond opening  106  and can allow for a seal when the closure flap is positioned over and seals opening  106 . In some embodiments, outer edge  609  can additionally aid in rotation of the closure flap over the lid base. 
     Turning to  FIG.  6 B , an example cross-sectional side view of a closure flap is shown in accordance with some embodiments of the disclosed subject matter. Note that, in some embodiments, side edges of a closure flap can have any suitable shape(s) (e.g., angles, curves, bends, arches, cuts, bumps, molds, and/or any other suitable designs), such as shown in and described below in more detail in connection with  FIGS.  7 A,  7 B,  7 C, and  8   . 
     Turning to  FIG.  6 C , an example side view of a closure flap is shown in accordance with some embodiments of the disclosed subject matter. Note that, in some embodiments, side edges of a closure flap can have any suitable shape(s), as shown in and described below in more detail in connection with  FIGS.  7 A,  7 B,  7 C,  8 ,  9 B,  9 C , and/or  9 D. 
     Turning to  FIGS.  7 A,  7 B, and  7 C , example cross-sectional side views of closure flaps, with a tab and a lid base, of different shapes inserted into an opening of a lid base are shown in accordance with some embodiments of the disclosed subject matter. Note that  FIGS.  7 A,  7 B, and  7 C  each show three different potential edge shapes  702 ,  704 , and  706 , respectively, of closure flaps. Additionally, note that the shapes of closure flaps shown in  FIGS.  7 A,  7 B, and  7 C  are shown merely as examples, and, in some embodiments, any suitable shape can be used. Note that additional possible shapes of closure flaps are shown in and described below in connection with  FIGS.  8 ,  9 B,  9 C , and/or  9 D. Additionally, note that, in  FIGS.  7 A,  7 B, and  7 C , outer edge  609  of each closure flap is shown on top of lid base  100 . 
     Note that, in some embodiments, the closure flap and/or bumps on the closure flap can each be made of any suitable material. For example, in some embodiments, the closure flap and/or the bumps can each be made of the same material as the can, such as aluminum or an aluminum alloy. In some embodiments, the closure flap and/or the bumps on the closure flap can each be made of any suitable material that allows the closure flap and/or the bumps to be recycled along with the can. 
     Additionally, note that, in some embodiments, the closure flap can have a depressed pocket (e.g., a depressed pocket  708  as shown in  FIG.  7 A ) in the center that has dimensions that correspond to dimensions of an opening of an open can (e.g., opening  106  as shown in and described above in connection with  FIG.  1 B ). 
     In some embodiments, a bottom portion of the closure flap can have a lining sealant (e.g., lining sealant  710  as shown in  FIG.  7 A ) of any suitable material, such as the same coating as the interior of the can body or any other suitable material. Note that, in some embodiments, any suitable type of sealant can be used, such as a sealant used in a lining or interior of the can (e.g., epoxy resin, any suitable polymer plastic, and/or any other suitable sealant). In some embodiments, the sealant can be any suitable sealant that satisfies any suitable criteria, such as being harmless to a consumer (e.g., BPA-free, and/or any other suitable harmless sealant), recyclable with aluminum, does not contaminate and/or change a taste of a beverage in a can, and/or that satisfies any other suitable criteria. In some embodiments, the lining sealant can have any suitable layers and/or can have any suitable thickness that can aid in sealing the opening of the can end and/or can aid in ease of use. In some embodiments, the lining sealant can have any suitable dimensions to correspond to a portion of a bottom of a corresponding closure flap or to the entire bottom of a corresponding closure flap. Additionally or alternatively, note that, in some embodiments, the closure flap can be covered prior to first use with a breakable sealant that prevents contaminants from entering an area under the closure flap. 
     Turning to  FIG.  8   , example cross-sectional side views of closure flaps of different shapes are shown in accordance with some embodiments of the disclosed subject matter. As illustrated, eight shapes,  802 ,  804 ,  806 ,  808 ,  810 ,  812 ,  814 , and  816  are shown with multiple design options and/or combination options. Note that, as illustrated in  FIG.  8   , a closure flap can have any suitable dimensions, and any suitable shape that includes any suitable angles, cuts, edges, padding, grooves, molds, lips, pressure points, curls, and/or any other suitable designs. 
     In some embodiments, a closure flap can have sections that can include: 1.) depressed pocket  708  (as shown in and described above in connection with  FIG.  7 A ); 2.) a closure seal lock area  826 ; and 3.) outer edge  609  (as shown in and described above in connection with  FIG.  6   ). For example, in some embodiments, depressed pocket  708  can be various depths, angles, shapes, and/or widths in relationship to a closure seal lock area  826  for insertion inside of a lid base opening and/or insertion inside of a holding area of a lid base pocket (e.g., lid base pocket  210  of  FIG.  2 B ), to accommodate movement of the closure flap (e.g., during rotation or positioning of the closure flap during opening or closing) and/or to aid in insertion of the closure flap in a lid base opening. 
     As another example, in some embodiments, as shown in shapes  812 ,  814 , and  816 , the closure flap can include a straight edge  818  that is connected to angle drop  819  of any suitable angle (e.g., 40 degrees, 45 degrees, 50 degrees, and/or any other suitable angle), that leads to an under-cut/indent  820  that acts as a hook. In some embodiments, under-cut/indent  820  can be positioned underneath an edge of opening  106  once lid base  100  is open. In some embodiments, this can allow for a seal of the closure flap over opening  106  such that the seal does not interfere with link  112  but allows the closure flap to work in conjunction with link  112  to seal a lid base opening. 
     As yet another example, in some embodiments, outer edge  609  of shape  814  can act with a spring-like action when the closure flap is depressed in the middle via an attached tab to provide resistance or assistance when the closure flap is depressed in a lid base opening and/or when the closure flap is rotated by a coupled tab. Note that shape  814  includes an upward arch and downward bend  822  into a curled edge  824  that can tuck under the arch  822  and which can sit on top of a drip catch of a lid base, which can be used to provide the spring-like action, resistance, pressure, and/or any other suitable function to assist a tight and non-leakable seal of the closure flap over a lid base opening and a link of a lid base opening (e.g., link  112 , as shown in and described above in connection with  FIG.  1 B ). Additionally, in some embodiments, curled edge  824  can provide a smooth surface area to an outer edge  609  of the closure flap such that the closure flap does not have an abrasive edge. 
     In some embodiments, a lid base can have a slide area in which a closure flap can move during rotation of the closure flap in and out of a lid base opening. In some embodiments, the slide area can aid in movement and/or rotation of the closure flap. Turning to  FIG.  11   , a top view of a lid base is shown in accordance with some embodiments of the disclosed subject matter. As illustrated, the lid base has a slide area  1102 . In some embodiments, slide area  1102  can be level with a scored flap of the lid base (e.g., scored flap  104 ). Alternatively, in some embodiments, slide area  1102  can slope in any suitable direction (e.g., upward toward scored flap  104 , downward toward scored flap  104 , and/or in any suitable direction). Note that, in some embodiments, slide area  1102  can be any suitable portion of the lid base. For example, in some embodiments, as shown in  FIG.  11   , slide area  1102  can be a subset of the top area of the lid base (e.g., a right side of the lid base, a left side of the lid base, and/or any other suitable area of the lid base). As another example, in some embodiments, slide area  1102  can be a full top portion of the lid base. Note that, in some embodiments, slide area  1102  can be used in connection with any combination of any suitable tab, rivet(s), closure flap, scored area, link(s), and/or any other suitable elements of a can end described herein. 
     In some embodiments, as shown in  FIG.  11   , the lid base can include a push button  1103 . In some embodiments, push button  1103  can act as a pressure point. In some embodiments, push button  1103  can be depressed to aid in rotation of closure flap out and away from the lid base opening to re-open the can end by loosening a connection of the closure flap within the lid base opening. Note that, in some embodiments, push button  1103  can be included in any suitable lid base and can be located at any suitable position on the lid base. Additionally, note that, in some embodiments, push button  1103  can be of any suitable shape and/or size (e.g., round, square, rectangular, triangular, L-shaped, and/or any other suitable shape). In some embodiments, push button  1103  can be formed via any suitable manufacturing technique(s) (e.g., any suitable molding technique, a pulled or pushed force manufacturing technique(s) as part of the lid base, welded onto the lid base, extruded from the lid base, and/or any other suitable technique(s)). In some embodiments, push button  1103  can be omitted. 
     Turning to  FIGS.  9 A,  9 B,  9 C,  9 D, and  9 F , another example of a tab and a closure flap are shown in accordance with some embodiments of the disclosed subject matter. 
     Turning to  FIG.  9 A , a top view of a tab  902  connected to a closure flap  906  and lid base is shown in accordance with some embodiments of the disclosed subject matter. As illustrated, tab  902  can include a tab rivet area  910 , a lip  916 , and/or a middle bar  918 . Note that  FIG.  9 F  shows a top view of tab  902 . 
     In some embodiments, tab rivet area  910  can correspond to a rivet that is used to couple tab  902  to the lid base. Note that, similar to what is described above, in some embodiments, a rivet used in connection with tab rivet area  910  can be any suitable rivet, such as an independent rivet (e.g., as shown in and described above in connection with  FIGS.  4 A,  4 B , and/or  4 C), a rivet that is part of a lid base (e.g., as shown in and described below in connection with  FIG.  10   ), and/or a rivet that is part of tab  902  at a location of tab rivet area  910  (e.g., as shown in and described below in connection with  FIG.  3 E ). 
     In some embodiments, middle bar  918  can engage with closure flap  906  in any suitable manner. For example, in some embodiments, middle bar  918  can fasten to or otherwise engage with a platform area  908  (e.g., as shown in  FIGS.  9 B and  9 C ) of closure flap  906 . As another example, in some embodiments, tab opening  318  (as shown in  FIG.  3 C ) can fasten to and/or engage with a closure flap bump  904 , as shown in  FIGS.  9 A and  9 B . As yet another example, in some embodiments, middle bar  918  can engage with any suitable independent rivet, such as a rivet  912  shown in  FIG.  9 E . 
     Turning to  FIG.  9 B , a side view of tab  902  and closure flap  906  is shown in accordance with some embodiments of the disclosed subject matter. 
     Turning to  FIGS.  9 C and  9 D , a top view of closure flap  906  and a side view of closure flap  906 , respectively, are shown in accordance with some embodiments of the disclosed subject matter. As illustrated, closure flap  906  includes a bump  904  on platform area  908 . In some embodiments, bump  904  can engage with tab  902  by being inserted through a circular tab opening of tab  902  (e.g., tab opening area  318 , as shown in  FIG.  9 F ). Referring back to  FIG.  9 A , in some embodiments, when bump  904  is inserted into the circular tab opening  318  of tab  902 , bump  904  can act as a rivet that couples tab  902  and closure flap  906 . For example, in some embodiments, bump  904  can be flattened (e.g., by a machine that applies pressure to bump  904 ), thereby causing bump  904  to act as a rivet that couples tab  902  and closure flap  906 . Note that, in instances in which bump  904  acts as a rivet that couples tab  902  and closure flap  906 , bump  904  can couple tab  902  and closure flap  906  such that tab  902  and closure flap  906  rotate together in conjunction, thereby acting as a lock mechanism that can aid in tab  902  rotating closure flap  906 . In some embodiments, when bump  904  is flattened, bump  904  can create a lip (e.g., as shown in and described below in connection with  FIG.  9 G ) to keep tab  902  connected to closure flap  906 . 
     Note that, as shown in section  920  of  FIG.  9 C , in some embodiments, platform area  908  can extend or protrude from an outer edge of the closure flap. In some embodiments, section  920  can increase a distance between rivet area  616  and a depressed pocket area of closure flap  906 . In some embodiments, platform  908  can have any suitable dimensions (e.g., length, width, thickness, etc.), and platform  908  can protrude from the outer edge of the closure flap by any suitable amount. 
     Turning to  FIGS.  10 A,  10 B, and  10 C , examples of a lid base  1002  with different lid base rivet area designs are shown in accordance with some embodiments of the disclosed subject matter. Note that, in some embodiments, lid base  1002  can have any suitable outer rim (e.g., an industry-standard can end outer rim, and/or any other suitable outer rim), which can be attached and sealed to a body of a can in any suitable manner (e.g., a double-seam method, and/or in any other suitable manner). Note that, in some embodiments, any suitable tab and/or closure flap can be used in connection with any of the lid bases shown in  FIGS.  10 A,  10 B , and/or  10 C. 
     Referring to  FIG.  10 A , lid base  1002  can include a protuberance  1004 . In some embodiments, protuberance  1004  can be formed on lid base  1002  in any suitable manner. For example, in some embodiments, protuberance  1004  can be formed via any suitable manufacturing technique(s) (e.g., any suitable molding technique, a pulled or pushed force manufacturing technique(s) as part of lid base  1002 , welded onto lid base  1002 , extruded from lid base  1002 , and/or any other suitable technique(s)). In some embodiments, protuberance  1004  can be closed at a top portion of protuberance  1004 . In some embodiments, protuberance  1004  can function as a rivet that can couple a closure flap and a tab to lid base  1002 . For example, in some embodiments, protuberance  1004  can be inserted through a round shaped closure flap rivet area and through a round shaped tab rivet area. Continuing with this example, in some embodiments, protuberance  1004  can then be flattened in any suitable manner to allow protuberance  1004  to function as a rivet. In some embodiments, protuberance  1004  can be flattened in any suitable manner, such as by a machine that depresses protuberance  1004  and/or applies pressure to protuberance  1004  in any suitable manner. 
     Turning to  FIG.  10 B , an example of lid base  1002  with a hollow protuberance  1006  is shown in accordance with some embodiments of the disclosed subject matter. In some embodiments, hollow protuberance  1006  can be formed in any suitable manner.

Additionally, note that, in some embodiments, a rivet that is part of tab  350  can be formed in any suitable manner. For example, in some embodiments, a rivet can be adhered to tab  350  (e.g., welded to tab  350 , pulled or pushed force or other suitable manufacturing technique as part of tab  350 , and/or adhered in any other suitable manner), formed via any suitable mold, extruded, and/or formed in any other suitable manner. 
     In some embodiments, a rivet that is a part of tab  350  can be any suitable shape, and can include any suitable sections, each having any suitable shape. For example, in some embodiments, tab  350  can include a rivet  351  that has a circular shape. As another example, in some embodiments, tab  350  can include a rivet  352  that can include a triangular section that can act as a lock above a circular portion of rivet  352 . As yet another example, in some embodiments, tab  350  can include a rivet  353  that includes a square section that can act as a lock above a circular portion of rivet  353 . 
     In some embodiments, a circular portion of a rivet that is part of tab  350  can be inserted through a circular closure flap rivet area (e.g., circular closure flap rivet area  616 , as shown in  FIG.  6 A , and/or any other suitable circular closure flap rivet area) and then through a circular lid base rivet area (e.g., lid base rivet area  204  as shown in  FIG.  2 B , hollow protuberance  1006  as shown in  FIG.  10 B , rivet opening  1008  as shown in  FIG.  10 C , and/or any other suitable circular lid base rivet area). 
     In some embodiments, a rivet can then be attached to the connected lid base, closure flap, and tab in any suitable manner. For example, in some embodiments, the rivet can be flattened in any suitable manner, such as by a machine that depresses the rivet from an underside of the lid base after the rivet is inserted through the lid base rivet area. Turning to  FIG.  3 F , an underside of a lid base after a rivet is inserted and flattened is shown in accordance with some embodiments of the disclosed subject matter. As illustrated,  FIG.  3 F  includes a flattened rivet  354  that has been flattened by any suitable machine that applies pressure to the rivet after insertion through the lid base rivet area. 
     Turning to  FIG.  9 G , an example cross-sectional view of a machine flattened rivet is shown in accordance with some embodiments of the disclosed subject matter. As illustrated,  FIG.  9 G  includes a flattened rivet  930 , and a side portion  932 . In some embodiments, flattened rivet  930  can correspond to any suitable rivet that is created using any suitable technique(s), as described above. Note that, in some embodiments, flattened rivet  930  can correspond to an independent rivet, a rivet that is part of a tab, a rivet that is part of a lid base, and/or any other suitable rivet. For example, in some embodiments, flattened rivet  930  can correspond to an independent rivet as shown in and described above in connection with  FIGS.  4 A,  4 B , and/or  4 C.
