CROSS-REFERENCE TO RELATED CASES 
     This application is a continuation-in-part of a co-pending U.S. application Ser. No. 12/562,361 filed on Sep. 18, 2009, the contents of which are incorporated herein by reference in its entirety. 
    
    
     FIELD OF THE INVENTION 
     The present disclosure relates generally to a container lid and more particularly to an attachable container lid containing compartments for holding and selectively dispensing additive substances. 
     BACKGROUND 
     Containers of various designs for separately holding additive substances until they are ready to be mixed with a solvent fluid are known. However, many are limited in their capacity to hold different number of component substances and impractical in configuration for efficient manufacturing. Thus, there is a need for improved lid for a container. 
     SUMMARY 
     According to an embodiment of the present disclosure, a container lid for mixture of two or more substances is disclosed. The container lid comprises a top portion provided with an actuator and a main portion, wherein the top portion and the main portion are rotatably attached to each other and rotatable about the central axis of the container lid. The main portion of the container lid is comprised of a closed top end, open bottom end and a central axis, wherein the top end is operably connected to the top portion. The main portion of the container lid also includes three or more compartments having closed top ends and open bottom ends. The closed top ends of the three or more compartments are incorporated into the closed top end of the main portion of the container lid. A plunger member is provided within each of the three or more compartments and the plunger members are connected to the closed top ends of the three or more compartments. The top portion and the main portion are rotatably attached to each other and rotatable about the central axis of the main portion. One of the three or more compartments is a major compartment that is larger than the other of the three or more compartments. The plunger member of the major compartment is positioned along the central axis and the actuator is always in alignment with the plunger mechanism of the major compartment. The plunger members of the other of the three or more compartments are equidistant in radial direction from the central axis. 
     According to another embodiment, the container lid for mixture of two or more substances further includes a sealing member closing the open bottom ends of the three or more compartments. When the plunger member is moved from its initial position to an actuated position by aligning the actuator to the compartment associated with the particular plunger member and pushing down on the actuator, the plunger member is urged against the sealing member and unseals the sealing member. 
     The container lid of the present disclosure can be utilized to introduce a selection of additives to a primary substance to provide a mixture. For example, configuring the container of the present disclosure into a cap for a bottled water, a selection of flavoring additives can be discharged into the bottle when desired to produce flavored water drink. 
     The cap or lid is designed to be packaged with a plunger member in an initial neutral position for shipping which prevents accidental triggering of the plunger member. The container lid can be configured to be threaded or screwed on to another container such as a beverage bottle. In another embodiment, the container lid can be molded over a metal bottle cap that will contain holes for accommodating the actuating plunger member. 
     Thus, the container lid of the present disclosure can be used for flavoring various types of beverages, for adding additives to liquid medicines, or adding a desired scent to a liquid cleaner, for example. The container lid can also be used for introducing precisely pre-measured amounts of chemical components for making mixtures or solutions, such as, the components of multi-part epoxies. 
     The container lid of the present disclosure provides an apparatus for the internal mixture of substances that is easy and convenient to use. The container of the present disclosure provides a compartmentalized mixture of fluids and thus utilization of more than one flavor independently or together. The contents of the differing compartments may be interspersed at the choice of the user.

     DETAILED DESCRIPTION 
       FIGS. 1 and 2  show a container lid  100  for holding two or more additive substances to be selectively discharged into a container according to an embodiment of the present disclosure. The container lid  100  comprises a top portion  110  and a main portion  120 . An actuator button  112  for actuating the container lid  100  is provided on the top portion  110 . 
     The top portion  110  and the main portion  120  are configured and adapted to be rotatably connected so that the top portion  110  and the main portion  120  are rotatable relative to each other about the central axis A of the container lid  100 . The top peripheral region  122  of the main portion  120  is configured and adapted for rotatably engaging the top portion  120 . The top peripheral region  122  comprises a substantially vertical annular wall portion  124 . The vertical annular wall  124  is provided with a protruding ridge  123  that circumscribes the outer surface of the vertical annular wall  124 . 
     Referring to  FIGS. 2 and 4 , the top portion  110  is configured with a substantially vertical annular lip  114  corresponding to the vertical annular wall  124  of the main portion  120 . The vertical annular lip  114  of the top portion  110  is configured and adapted for rotatably engaging the vertical annular wall  124 . In the illustrated example, the vertical annular lip  114  is provided with a groove  116  along its inner surface that engages the protruding ridge  123  of the main portion  120 . The top portion  110  and the main portion  120  are made from a suitable material so that the top portion  110  and the main portion  120  can be snap fitted together by the engagement of the groove  116  and the protruding ridge  123 . Once snap fitted together, the top portion  110  and the main portion  120  can be rotated relative to each other about the central axis A while the two portions are held together by the mechanical interference between the groove  116  and the ridge  123 . The curvatures of the vertical annular wall  124  and the annular lip  114  are matched to provide smooth rotating motion between the top portion  110  and the main portion  120 . 
       FIGS. 3 and 4  are exploded isometric views of the container lid  100  from two different angles to show the details of the structures. In  FIG. 3 , the closed top end  125  of the main portion  120  is shown. The main portion  120  is provided with two or more compartments  136  for holding additive substances. The two or more compartments  136  have open bottom ends (see  FIG. 4 ) and closed top ends  127 . The closed top ends  127  are connected with the closed top end  125  of the main portion  120 . The closed top ends  127  of two or more compartments  136  are visible in  FIG. 3 . As can be seen, in a preferred embodiment, the closed top ends  127  of the compartments  136  are integrally formed with the closed top end  125  of the main portion  120 . 
     Referring to  FIGS. 4 and 5 , the main portion  120  has an open bottom end. The main portion  120  comprises an inner wall  130  structure that defines a central region separated by a space  140  from the outer wall. The central region defined by the inner wall  130  is divided into the two or more compartments  136  by dividers  135 . In the illustrated example, the main portion  120  has four compartments  136  formed by four dividers  135 . According to a preferred embodiment, the dividers  135  are arranged in radially symmetrically about the central axis A forming two or more compartments  136  that are equal in size and positioned radially symmetrically about the central axis A. This would allow equal amounts of additive substances to be held in each of the two or more compartments  136 . 
     Provided within each of the two or more compartments  136  is a plunger member  133 . As shown in the cross-sectional views in  FIGS. 5-6 , the plunger members  133  are connected to the closed top ends  127  of the two or more compartments  136 . In a preferred embodiment, the top ends  127  of the compartments  136  are integrally formed with the closed top end  125  of the main portion  120 . In a preferred embodiment, the plunger members  133  are also integrally formed with the closed top ends  127  of the compartments  136 . Thus, the entire main portion  120  can be formed as one integral member by molding the structure in one single mold allowing the main portion  120  to be manufactured by a single molding process. For example, each of the main portion  120  and the top portion  110  are injection molded as integral pieces using an appropriate material such as a polymer material and then assembled together. 
     Referring to  FIG. 4 , on the bottom (or the inner) side of the top portion  110 , a center support member  115  is provided to provide some structural support in the center region of the top portion  110 . The actuator button  112  in this embodiment has a dome-like structure and has a stem  113  about its center on the bottom side. The actuator button  112  is located on the major surface of the top portion  110  off-center. Off-center position refers to the fact that the actuator  112  is located between the central axis A and the periphery of the top portion  110 . The actuator  112  and the closed top end  127  of the compartments  136 , to which the plunger members  133  are connected, are positioned equidistant in radial direction from the central axis A so that the actuator  112  can be aligned with the plunger member  133  associated with one of the compartments  136  by rotating the top portion  110  to a desired position relative to the main portion  120 . Thus, when a particular additive substance being held inside one of the compartments  136  is to be discharged, the user rotates the top portion  110  until the actuator button  112  is aligned with the compartment  136  holding the desired additive substance and depresses the actuator button  112 . The stem  113  of the actuator button  112 , in turn, pushes down on the closed top end  127  of that particular compartment  136  and pushes the plunger member  133  down from its initial position to actuated position. 
       FIGS. 6 and 7  show the container lid  100  assembly holding additive substances S in the two or more compartments  136 . The open bottom ends of the compartments  136  are sealed by a sealing member  180 . The actuator button  112  is shown aligned over one of the compartments  136  and still in its initial position. In  FIG. 8 , the actuator button  112  has been pushed down into its actuated position. The stem  113  of the actuator button  112  has pushed down on the top portion  127  of the compartment and the plunger member  133  has also been pushed down to its activated position. In the activated position, the plunger member  133  extends through the bottom end of the compartment  136  and has broken through the sealing member  180  discharging the content S. 
     In a preferred embodiment, the dome-like structures of the actuator button  112  and the closed top ends  127  of the two or more compartments  136  are structured to function like a bellville washer. This means that once they are pushed down into their actuated positions shown in  FIG. 8 , the actuator button  112  and the closed top end  127  do not return to their initial positions and remain in the actuated positions. This creates a mechanically locked configuration between the top portion  110  and the main portion  120  and prevents the top portion  110  from being rotated further.  FIG. 8A  shows an alternate embodiment where the step  113  and the closed top end  127  have interlocking hook structures to keep them locked in the actuated configuration. 
     The locking embodiment can be utilized in applications where limiting the user from discharging more than one of the additive substances from the container lid  100 . If the limitation is not necessary, the actuator button  112  can be structured so that the actuator button  112  returns to its initial position after actuation. This will allow the user to select another of the two or more compartments  136  for actuation and discharge additional additive substances. This may be desired in beverage application where the consumer may elect to make a drink using more than one or all of the flavor additives provided in the container lid  100  assembly. 
     The sealing member  180  can be a sealing structure that is readily breakable or removed by the downward movement of the actuating plunger member  133 . In a preferred embodiment, the sealing member  180  is comprises an appropriately frangible membrane such as a metal foil or a polymer membrane that is bonded to the open bottom ends of the two or more compartments  136 . Such membranes can be bonded to the open bottom ends adhesively or by ultrasonic bonding or other suitable bonding methods available to one of ordinary skill in the art. If a metal foil membrane is used for the sealing member  180 , the metal foil can be coated with or bonded to a protective layer of polymer material that can prevent the metal from reacting with the contents of the compartment  136 . The metal foil embodiment of the frangible membrane can be coined or stamped with an appropriate pattern to facilitate breaking of the membrane by the actuating plunger member  133 . 
     Referring back to  FIG. 3 , at least one plug or a pedestal structure  126  is provided between two adjacent top ends  127  of the two or more compartments  136  for preventing the actuator button  112  from being accidentally depressed when the top portion  110  is dialed into its “neutral” position where the actuator button  112  and the pedestal structure  126  are aligned. The pedestal structure  126  is sufficiently tall so that it contacts the stem  113  of the actuator button  112  and prevents the actuator  112  from being depressed. Preferably, if the container lid  100  is being shipped with its two or more compartments filled with additive substances and sealed, the top portion  110  is dialed into its “neutral” position to prevent accidental activation of any of the compartments. 
     Referring to  FIGS. 3 and 6 , the protruding ridge  123  of the main portion  120  can be provided with a plurality of notches  123   a  and the groove  116  of the top portion  110  can be provided with a bump  117  for assisting the user with the alignment of the actuator button  112  to a desired compartment  136 . The bump  117  represents the position of the actuator button  112  and the notches  123   a  represents the locations of the two or more compartments. The bump  117  and the notches  123   a  are positioned such that as the top portion  110  is rotated, when the actuator button  112  comes in alignment with any one of the two or more compartments  136 , the bump  117  also comes in alignment with the notch  123   a  that is associated with the particular compartment and provide tactile and/or audible “click” so that the user knows that the actuator button  112  is in alignment with a compartment. For example, in the illustrated embodiment, the bump  117  is in a radial alignment with the actuator button  112  as shown in  FIG. 6 . The notches  123   a  are in radial alignment with the position of each of the two or more compartments  136  (represented by the closed top ends  127  of the compartments) as shown in  FIG. 3 . Preferably, visual markings  190   a ,  190   b  can also be provided on the exterior of the top portion  110  and the main portion  120  to aid the user in aligning the actuator button  112 . The visual marking  190   a  on the top portion  120  represents the position of the actuator button  112  and the visual markings  190   b  represent the positions of the two or more compartments  136 . Alternatively, the main portion  120  can be made from a transparent material so that the two or more compartments  136  and their contents are readily visible to the user to aid in aligning the actuator button  112  with the desired compartment. 
     As shown in  FIGS. 5 and 6 , the main portion  120  is configured and adapted to be attachable to a second container  500 . The inner wall  130  defines a space  140  between the inner wall  130  and the inside surface  128  of the outer wall. The space  140  is configured to engage an opening of a vessel  500  such as a water bottle. In the example shown here, the inside surface  128  of the outer wall is provided with screw threads  129  for engaging the threaded opening of the second container  500  commonly found in water bottles and other beverage bottles.  FIG. 9  shows such an embodiment of the container lid  100  threaded onto a container  500 . The container  500  contains water  510  and the container lid  100  can be filled with various flavoring additives that can be selectively discharged by the consumer to create a desired beverage. 
     The main portion  120  can be configured and adapted with a variety of different structures for engaging different types of vessel configurations. For example,  FIG. 10  shows the container lid  100  assembly mounted to a metal crown bottle cap  600 . The metal bottle cap  600  is similar to the metal crown bottle caps commonly found on some beverage bottles but has holes  610  provided therein for accommodating the plunger member  133  and to allow the contents of the container lid  100  to be discharged through the bottle cap  600 . The holes  610  allow the plunger member  133  to be pushed through as the plunger breaks through the frangible sealing membrane  180 . The container lid  100  assembly with the metal bottle cap  660  attached to the bottom can be used to cap bottles containing the solvent substance. The container lid  100  can be attached to the metal bottle cap  660  by one of a variety of methods available and known to one of ordinary skill in the art. 
     The various embodiments of the container lid  100  described above can be used in beverage industry, for example, to provide drinks that can be flavored with a desired flavor or fortified with a desired nutritional additive at the time of consumption by the consumer. The container lid  100  can be prefilled and sealed with two or more additives in the two or more compartments. In one embodiment, the container lid  100  can be sold to the consumer directly. The consumer can attach the pre-filled container lid  100  to a bottle of water, for example, and select and discharge the desired additive into the bottle of water just before consumption. The selection and discharge is accomplished by turning the rotatable top portion  110  to the desired compartment and activating that compartment by pushing down on the actuator button  112 . In the metal bottle cap embodiment shown in  FIG. 10 , the soda bottles capped with the metal bottle cap having container lid would be sold to the consumer. The consumer would select the desired flavor for the soda beverage by dialing the rotatable top portion  110  to the desired compartment and activating that compartment. 
     Referring to  FIGS. 11A and 11B , in another embodiment, the sealing member  180  can be a piston or a plug like structure to which the plunger member  133  is attached as shown. The plunger member  133  and the plug  180  can be attached by an appropriate mechanical fitting configuration for ease of assembly. For example, a hole can be provided on the plug  180  into which the bottom end of the plunger member  133  would be inserted. The dimensions of the hole and the plunger member  133  would be such that the two structure would fit sufficiently snuggly to prevent the plug  180  from falling out. Alternatively the plug  180  and the plunger member  133  can be configured to snap fit into each other. In any event, when the plunger member  133  is activated the plug  180  is pushed down and out of the bottom end of the compartment  136  allowing the content S to be discharged as shown in  FIG. 11B . When the plunger member  133  is activated the plunger member  133  pushes the piston  180  down and unseal the compartment  136 . 
       FIGS. 12A-17  disclose additional embodiments according to the present disclosure.  FIG. 12  shows a container lid assembly  1  for mixture of substances and comprises a rotatable top portion  2  and a main portion  4 . The top portion  2  is provided with an actuator  3 . The main portion  4  has a top edge  5  in communication with a bottom edge  6  of the rotatable top portion  2 . The main portion  4  is configured with two or more compartments  7  and at least one plunger member  8  provided within each of the compartments  7 . The plunger members  8  are configured to be actuated from their initial position to actuated position by means of the actuator  3 . The two or more compartments  7  are provided in a central portion  9  of the main portion  4  and are open on the bottom end. The main portion  4  has an outer wall  10  that is separated from the central portion  9  defining a space E between the central portion  9  and the outer wall  10 . The outer wall  10  and the central portion  9  defining the space E can be configured and adapted for engaging an opening of another container such as the bottle  500  in the embodiment shown in  FIG. 7 . 
     The container lid assembly  1  can be permanently affixed or removably attachable to a container. In operation, the bottom portion  4  of the container lid assembly  1  can be attached to a container, such as a beverage bottle, by any means known in the industry, including but not limited to threading, swaging or clamping. Subsequently, the rotatable top portion  2  is rotated into position until the actuator  3  is aligned with one of the two or more compartments  7 . Then, when the actuator  3  is depressed, the plunger member  8  is in turn depressed into its actuated position. Each of the two or more compartments  7  has a closed top end  18  that is integrally formed with the main portion  4 . The plunger member  8  is connected to the closed top end  18  and preferably also integrally formed with the closed top end  18 . The arcuate bellville washer like configuration of the closed top end  18  functions to lock the plunger member  8  in the pushed-down actuated position upon activation of the plunger member using the actuator  3 . The open bottom ends of the compartments  7  can be sealed with a sealing member  15  after component substances are placed in the compartments  7 . In one preferred embodiment, the sealing member  15  is a frangible membrane that is broken open by the plunger member  8 , such as a metal foil, upon activation of the plunger member  8 . In  FIG. 15 , the compartment  7  on the left side of the figure is shown with a sealing member  15  sealing the open bottom end of the compartment. The sealing member  15  can be made of penetrable membrane such as a foil membrane or any other kind of material which is easily penetrable by the plunger member  8 . 
       FIGS. 13 and 14  shows top-down views of the main portion  4  and the top portion  2 . In this illustrated example, the main portion  4  is provided with four compartments  7  arranged in radially symmetric manner so that the main portion  4  is divided into four quadrants, each quadrant being one of the two or more compartments  7 . 
     In one embodiment of the container lid  1 , the plunger mechanism  8  may contain a serrated edge  11  to facilitate breaking through the sealing member  15 . In this configuration, once the actuator  3  is depressed, the plunger member  8  breaches the penetrable sealing member  15 , allowing the contents of the compartment  7  to be discharged. 
       FIG. 16  shows an isomeric view of the container lid assembly  1  showing the top portion  2  and the main portion  4  rotatably engaged to each other. 
     Referring to  FIG. 17 , in a further embodiment of the lid container, the open bottom end of the two or more compartments  7  can be sealed by unidirectional flow valves  13 . The bottom ends of the plunger member  8  are configured as pistons  28  and upon depression of the actuator  3  aligned over one of the two or more compartments  7 , the plunger mechanism  8  and the piston  28  in that particular compartment moves downward and forces the contents of the compartment  7  out through the unidirectional flow valve  13 . In such embodiment, the contents of the compartments  7  would preferably be liquid substance. The unidirectional flow valve  13  may comprise a check valve or a tensioned flap. 
     As discussed above in connection with other embodiments, the actuator  3  and the closed top ends  18  of the two or more compartments  7  can be configured and adapted to lock the actuator  3  to the closed top ends  18 , and in turn to the plunger member  8 , upon activation of the actuator over one of the compartments  7 . Such locking configuration can be achieved by a permanent detent or other such mechanism as known in the art, such that upon activation, the locking mechanism  15  permanently secures the actuator  3  to the plunger. This locking mechanism serves to lock the actuator  3  and the plunger member  8  in actuated position and consequently, prevent the user from activating any of the other remaining compartments. In chemical solution mixing application, this feature ensures the integrity of the mixed solution, preventing over mixing and ensuring that the container lid assembly  1  is not readily reused. 
     Referring to  FIG. 18 , the principles of the container lids  1  and  100  discussed above can be adapted to a container having a main compartment holding a primary substance and two or more sub-compartments for holding additive substances that can be selectively discharged to make a mixture or solution with the primary substance.  FIG. 18  shows a container  100 A that has structures similar to the container lid  100  shown in  FIG. 7 . In the container  100 A, the outer wall of the main portion  120  extends further downward forming a bottom opening  150  defined by the bottom edge  120 E of the outer wall of the main portion  120 . When the bottom opening  150  is sealed by a second sealing member  180 A as shown, a main compartment space  16  is formed. A primary substance such as a liquid L can be placed into this main compartment space  16  before the second sealing member  180 A is placed in position. Similar to the first sealing member  180 , the second sealing member  180 A can be formed from the same selection of materials. For example, the second sealing member  180 A can be breakable membrane or a solid plug that can be threaded onto the outer wall of the main portion  120  or bonded to the main portion  120  in one of a variety of ways known in this art. 
     Furthermore, in another embodiment, the main compartment  16  can be configured into additional compartments by one or more dividers. Within each of these subdivided main compartments, two or more compartments  136  can be provided.

In a preferred embodiment, the plunger member  333  and in turn the corresponding depressible button  226  is located at the center of the main portion  220  in alignment with the central axis A of the container lid  200 . 
     The depressible button  226  is integrally formed with the closed top end  225  of the main portion  220  and comprises a center portion  226   a  and a flexible bellville washer-like portion  226   b . The flexible portion  226   b  allows the center portion  226   a  to be pressed downward which in turn moves the plunger member  333  downward similar to the plunger members  133 ,  8  and  233 . The main portion  220  can be formed as one integral member including the plunger members  233  and  333  similar to the main portion  120  of the container lid embodiment  100 . 
     The actuator  212  in this embodiment has a flexible dome-like structure and has a major stem  213  for engaging and actuating the depressible button  226  of the major compartment  336  and a minor stem  214  for actuating the depressible button  227  of two or more minor compartments  236 . The actuator  212  is also provided with a minor stem  214  located off-center on the bottom side of the top portion  210  for engaging and actuating the depressible button  227  as shown in  FIG. 20 . The minor stem  214  is located off-center so that it can be brought into alignment with the off-center positioned depressible buttons  227 . 
     In one embodiment, the actuator  212  itself is also located off-center on the top portion as shown to encompass both the major and minor stems  213 ,  214  on the bottom side of the actuator  212 . However, the actuator  212  can also encompass the whole top surface of the top portion  210  as long as the location of the major stem  213  and the off-centered location of the minor stem  214  are marked appropriately on the actuator  212  so that the user knows where to press down to actuate the plunger members  233 ,  333 . 
     When the top portion  210  is assembled with the main portion  220 , the centrally located major stem  213  is in alignment with the depressible button  226  of the major compartment  336 . The off-centered minor stem  214  and the two or more depressible buttons  227  are located equidistant from the central axis A such that the minor stem  214  and the two or more depressible buttons  227  can be brought into alignment by rotating the top portion  210  about the central axis A. 
     A top-down view of an assembled container lid  200  in  FIG. 21  illustrates the arrangement of the major and minor stems  213 ,  214  with respect to the depressible buttons  226 ,  227  in detail. The major stem  213 , minor stem  214  and the center portions  227   a  of the depressible button  227  are shown in broken lines. The major stem  213  is provided at or near the center of the top portion  210 . The center of the top portion  210  being identified by the central axis A. The minor stem  214  is positioned so that by turning the top portion  210  in the direction L or R marked by the arrows, the minor stem  214  is brought in alignment with the center portions  227   a  of the depressible buttons  227 . As shown in  FIGS. 19-21 , the top portion  210  and the main portion  220  can be provided with appropriate alignment markings M to enable the user to know when the minor stem  214  is in alignment with the depressible button  227  for the desired minor compartment  236 . 
     After the top portion  210  is dialed into a desired position, the contents of the major compartment  336  and one of the minor compartment  236  are discharged by pressing down on the actuator  212 . The actuator  212  can be configured to be sufficiently rigid so that by pressing down anywhere on the actuator  212  will push both the major stem  213  and the minor stem  214  down into the corresponding depressible buttons  226 ,  227  which in turn push the plunger members  333 ,  233  downward from their initial position into their actuated position and break the sealing member at the bottom ends of the compartments  336 ,  236 . Alternatively, the actuator  212  can be configured to be more flexible so that each of the major compartment  336  and the selected one of the two or more minor compartments  236  can be unsealed one at a time. This can be achieved by the user pressing down in to the appropriate portion of the actuator  212  corresponding to the locations of the major stem  213  and the minor stem  214  thus actuating the corresponding plunger members individually. 
     The center portions  227   a  can be provided with slots  221  for engaging the minor stem  214 . Because the major stem  213  is centrally located on the top portion  210 , as the top portion  210  is rotated about the central axis A, the major stem  213  remains in alignment with the depressible button  226  which is also centrally located on the main portion  220 . 
     Similar to the container lid embodiment  100  discussed above, in one preferred embodiment, the bellville washer-like portions  226   b ,  227   b  of the depressible buttons  226 ,  227  functions to lock the corresponding plunger members  333 ,  233  in their pushed-down actuated position upon activation of the plunger members. 
     Similar to the container lid embodiment  100  discussed above, the open bottom ends of the major and minor compartments  336 ,  236  can be sealed by a sealing member to hold the additive substances placed inside the major and minor compartments  336 ,  236 . When the plunger members  233 ,  333  are urged downward by pressing down the actuator  212 , the plunger members  233 ,  333  break the sealing member allowing the contents of the corresponding compartments to be discharged. Additionally, similar to the container lid embodiment  100 A shown in  FIG. 18 , the container lid embodiment  200  also can utilize a second sealing member (see  180 A of  FIG. 18 ) to close the open bottom end of the main portion  220  and define a main compartment.
