Description
- This application claims the benefit, under 35 U.S.C. § 119(e), to U.S.
provisional patent application 60/941,122, filed on May 31, 2007, the contents of the entirety of which are incorporated by this reference. - This invention relates to supplement containing and dispensing systems. It is particularly directed to a dispensing cap having a compartment that may be associated with a liquid container, and that is to contain supplements for ingestion with water or other beverage.
- Conventional beverage container and dispenser systems associated with compartments may be used with beverage supplements, such as a flavoring, an electrolyte, a vitamin, and a nutritional, mineral or medicinal additive. Dispenser systems are useful, particularly for ingredients that have a shortened shelf-life when mixed with a liquid. The dry or powdered ingredient may be stored in a compartment, and dispensed into the beverage immediately prior to consumption.
- Conventional dispenser systems may include different features. For example, a two-piece sealed capsule that is inserted into a liquid bearing container wall or neck of a bottle is disclosed in U.S. Pat. No. 6,886,686 to Anderson. A cylindrical body includes a sealed bottom integrally formed with the cylinder through a weakened wall area which defines the perimeter of the bottom of the body. A plunger tube is integrally formed with the bottom of the sealed body, and may be activated by manually depressing the top of the capsule, and ripping away the bottom of the cylindrical body, thus dispensing the material contained therein.
- The Anderson plunger tube may be difficult to manufacture, particularly in forming the integral tube and cylinder floor. In addition, because the capsule is inserted into the neck of the bottle, the system may not be used successfully with a full container of liquid.
- Another cap for a container, wherein two components of a drink may be stored separately, is disclosed in U.S. Pat. No. 6,230,884 to Coory. The cap includes a collar secured to the container and a two-part top. With the top in the open position, a basket between the top and the liquid holds the powdered component of the drink. The top is closed to release the seal between the liquid and the powder, the drink is shaken, and the top is reopened for consumption of the beverage. The cap disclosed in Coory requires an additional cover, releasable secured over the cap, to prevent the top from being closed accidentally and releasing the seal prematurely.
- A need exists for a supplement containing and dispensing system that is configured to temporarily associate a supplement with a beverage container. A system that is simple and inexpensive to manufacture, and usable with a number of different conventional beverage containers is particularly desirable.
- Described herein is a dispensing cap for a container with a top opening, the dispensing cap comprising: a body having a wall with an inside facing surface and a floor at least partially defining a chamber, the floor having at least one weakness therein; a plunger disposed within the chamber and having distal edges in contact with the inside facing surface of the wall of the chamber; and a mounting structure separated from the chamber by the chamber floor, and configured to engage with the top opening of the container. The plunger may comprise a piston and a cover, and the inside facing surface of the wall of the chamber may include channels configured to engage with the distal edges of the plunger. The cover of the plunger may include a central, substantially circular protrusion for engaging with the piston, and the cover of the plunger may be removable from the chamber.
- The weakness of the floor may comprise at least two intersecting lines of weakness, and the plunger may include a piston having four orthogonally disposed walls. The piston may be disposed within the chamber such that the walls of the plunger are offset from the at least two intersecting lines of weakness.
- The mounting structure may be configured to be disposed within the top opening of the container, or may be configured to engage threadedly with the top opening of the container.
- The chamber may include an inwardly protruding stop, which may be annular, and configured to engage with the plunger.
- Another embodiment of a dispensing cap for a container with a top opening comprises a body configured to engage with the top opening of the container and having a wall with an inside facing surface and a floor at least partially defining a chamber, the floor having at least two intersecting lines of weakness therein; and a plunger disposed within the chamber.
- The plunger may comprise a cover and a piston having four orthogonally disposed walls, and the inside facing surface of the wall of the chamber may include channels configured to engage with distal edges of the walls of the piston. The piston may be disposed within the chamber such that the walls of the plunger are offset from the at least two intersecting lines of weakness.
- The chamber may include an inwardly protruding stop that is annular, and is configured to engage with the plunger.
- Also disclosed herein is a dispensing system, comprising: a container with a top opening, a dispensing cap mounted on the container, the dispensing cap comprising: a body having a wall with an inside facing surface and a floor at least partially defining a chamber, the floor having at least one weakness therein; a plunger disposed within the chamber and having distal edges in contact with the inside facing surface of the wall of the chamber; and a mounting structure separated from the chamber by the chamber floor and configured to engage with the top opening of the container; and a supplement disposed within the chamber of the dispensing cap. The inside facing walls of the chamber may include channels configured to engage with the distal edges of the plunger.

Theintermediate floor 25 may be funnel-shaped to enable thesupplement 50 to enter the mountingstructure 30 with the aid of gravity.Support walls 40 may extend radially from theintermediate floor 25 to provide aflat support surface 45 when the dispensingcap 10 is placed on a beverage container. Theflat support surface 45 may seat against arim 62 of the beverage container 65 (FIG. 1B ). The dispensingcap 10 illustrated inFIG. 1 includes foursupport walls 40, however a dispensing cap including any number of support walls is within the scope of the invention. A dispensing cap including a body wall having an outside facing surface extending to the edge of the flat support surface is also within the scope of the invention. - A dispensing cap having no support walls is also within the scope of the invention. In use, a dispensing cap having no support walls may be matingly engaged with the
beverage container 65. The mountingstructure 30 may be received within theopening 67 of thebeverage container 65, and the outside facing surface of the funnel-shapedintermediate floor 25 may provide an annular seal with therim 62 of thebeverage container 65. The funnel-shapedintermediate floor 25 may be desirable with a beverage container having an opening with a relatively small cross-sectional area, with respect to the cross-sectional area of the storage compartment. Dispensing caps configured for use with beverage containers having relatively large openings, and an opening with a cross-sectional area substantially similar to the cross-sectional area of the storage compartment, may not include a funnel-shaped intermediate floor, as described hereinbelow with respect toFIGS. 6 through 11 . - Returning to
FIG. 2 , theplunger 70 may comprise acover 75 and apiston 80 positioned within the storage compartment. Thesupplement 50 may be sealed within thestorage compartment 24, between the inside facingsurface 27 of thebody 20, theplunger cover 75, theintermediate floor 25 and afloor 35 of thestorage compartment 24. Thepiston 80 may comprise four orthogonally disposedwalls 82. Eachwall 82 may taper toward acentral point 84 near thefloor 35 of thestorage compartment 24. Eachwall 82 has adistal edge 81 in contact with theinside facing surface 27. The taper of thewalls 82 may be configured to work with the funnel-shapedintermediate wall 25 of thebody 20. -
FIG. 3A depicts thebody 20 without theplunger 70, so thestorage compartment 24 may be viewed. Thebody 20 includes anopening 21 at the top for receiving theplunger 70. Theopening 21 may be substantially round. - The
inside facing surface 27 of thebody 20 includes alongitudinal channel 22 for guiding theplunger 70. Afirst indexing stop 90 may be annular, and inwardly protruding. Thefirst indexing stop 90 may be configured to engage with theplunger cover 75. During assembly of the dispensingcap 10, thefirst indexing stop 90 may provide a positive reinforcement that theplunger cover 75 is in the proper position, and does not need to be pushed further into thebody 20. The first indexing stop may also provide a safety, requiring more force to depress theplunger 70. In use, theplunger 70 is manually depressed to break thefloor 35 and dispense thesupplement 50. It may be desirable to retain the plunger in the depressed position, for example, so theplunger 70 holds thefloor 35 open, enabling fluid communication between the inside of thebeverage container 65 and thestorage compartment 24. Thefirst indexing stop 90 may engage with the top surface of theplunger cover 75, and prevent theplunger 70 from backing out of thebody 20. The user may shake thebeverage container 65 and dispensingcap 10, and the beverage may wash the supplement out of thestorage compartment 24. Thefirst indexing stop 90, shown in more detail inFIG. 3B , may include anengagement surface 92 which extends radially inwardly from theinside facing surface 27 of thebody 20. Theengagement surface 92 may engage with theplunger 70, and prevent the plunger from departing from the depressed position. Anupper surface 94 of the inwardly protruding stop may taper outward, from theinside facing surface 27 to the inside perimeter of theengagement surface 92. Thus, theplunger 70 may move past thefirst indexing stop 90 to the depressed position, but may not return to the original position. - Another embodiment of a
first indexing stop 90′ is shown inFIG. 3C . Thefirst indexing stop 90′ may comprise anannular recess 91′ on theinside wall 27′ of the body, to mate with anannular protrusion 93′ of theplunger 70. It is also within the scope of the invention for thefirst indexing stop recess 91′ in theinside wall inside wall inside wall plunger 70. A second indexing stop may also prevent the plunger from traveling too far within thebody 20. - The
inside facing surface 27 of thebody 20 may includelongitudinal channels 22 for guiding thedistal edges 82 of thepiston 80, as shown inFIG. 3A . In use, force may be applied by a user to thecover 75 of theplunger 70, forcing thepiston 80 to engage with and slide along thechannels 22 toward thefloor 35 of thestorage compartment 24. Thefloor 35 of thestorage compartment 24 may include a weakness, such that under the force of theplunger 70, thepiston 80 may pierce thefloor 35. Thefloor 35 may open along the weakness, enabling the supplement to exit thestorage compartment 24 via the mountingstructure 30 to mix with the beverage. The weakness may comprise a scored or reduced thickness region of thefloor 35, as further described hereinbelow with respect to the embodiment shown inFIG. 6 . - The
piston 80 is depicted inFIG. 4 . Thepiston 80 includes four orthogonally disposedwalls 82, however apiston 80 comprising a single planar body, as well as a piston comprising two, three, or more than four walls is also within the scope of the invention. Thewalls 82 may include thedistal edges 81 configured to engage with thechannels 22 of thestorage compartment 24. Thewalls 82 may taper at one end thereof to apoint 84. Thepoint 84 is positioned at one end of the piston at the intersection of thewalls 82. - The
piston 80 and thecover 75 of theplunger 70 may comprise discrete components as shown, however it is within the scope of the invention for theplunger 70 to comprise a unitary body. Thecover 75 may provide a surface for a user to engage and depress the plunger, and may also retain a supplement within the chamber. -
FIG. 5 depicts thecover 75 of theplunger 70. Thecover 75 may comprise a disc-shapedbody 76 sized to fit within theinside facing surface 27 of thebody 20. Thecover 75, theinside facing surface 27, theintermediate floor 25, and thefloor 25 define thestorage compartment 24. Anannular rim 77 may extend from the perimeter of the disc-shapedbody 76. Optionally, thecover 75 may include acentral protrusion 78 for engaging with thepiston 80. - The
body 20 and theplunger 70 may be formed of a polymer, for example polypropylene, polyvinyl or polyethylene. Thebody 20 and theplunger 70 may be formed, for example, by a molding process such as injection molding, transfer molding, or compression molding. Subsequent to forming thebody 20, thepiston 80 may be positioned within thebody 20, and thestorage compartment 24 may be partially filled with thesupplement 50. Thecover 75 of theplunger 70 may then be positioned withinbody 20. -
FIGS. 6 and 7 depict a second exemplary embodiment of a dispensingcap 100 including aspects of the invention. As illustrated, the dispensingcap 100 includes abody 120 having astorage compartment 124 therein and a mountingstructure 130, and aplunger 170. Thestorage compartment 124 enables temporary storage of asupplement 50 for use in conjunction with abeverage 60. Thesupplement 50 may be in any form such as, for example, a granule or powder, a tablet or pill, or a paste, liquid or syrup. Thesupplement 50 may be applied to thebeverage 60 as an additive prior to the beverage being imbibed, such as with flavors, sweeteners or electrolytes. Theplunger 170 may include aplunger cover 175 and apiston 180. - The mounting
structure 130 of thebody 120 may be configured to matingly engage with another container, for example a beverage bottle. The mountingstructure 130 may includeinterior threads 134 on an inside surface thereof, for matingly engaging with a beverage container having exterior threads. Alternatively, as shown inFIG. 8 , the mountingstructure 230 may have an inside surface which is substantially smooth, and be configured to rest over, or snap onto a container. - The
body 120 of the dispensingcap 100 includes awall 123. Theinside facing surface 127 of the wall, afloor 135 of thebody 120, and theplunger cover 175 may define astorage compartment 124. Thefloor 135 may include aweakness 26, pierceable by theplunger 170. - The
weakness 26 may comprise two troughs in the material of thefloor 135, arranged in a cross-shape, or “+” shape. The trough depth may be sufficient to enable tofloor 135 to rupture at theweakness 26, yet provide a fluid tight seal prior to the rupturing. Alternatively, theweakness 26 may comprise scoring along the desired breaking points. Theweakness 26 may be offset from the “+” shape of thepiston 80. Thepiston 80 may contact thefloor 35 at the point of intersection of the “+” and in locations between theweakness 26, and push the floor toward the channel, severing thefloor 35 along theweakness 26. -
Channels 122 on theinside facing surface 127 of thebody wall 123 may be configured to engage with the distal edges of thepiston 180. Thechannels 122 do not extend the entire length of thebody 120, rather, the channels extend from the proximal edge of the mountingstructure 130 to the bottom of the distal edges of thepiston 180. It is also within the scope of the invention for thechannels 122 to extend to the opening of thebody 120, as shown in the embodiment depicted inFIG. 3A . Thechannels 122 may enable the piston to remain in the desired alignment with respect to theweakness 26 of thefloor 135. Thepiston 180 may be aligned such that the four walls of thepiston 180 are offset from the four arms of thecross-shaped weakness 26. - The
first indexing stop 190 on the inside facing surface of thebody wall 123 may be configured to engage with theplunger cover 175. Asecond indexing stop 195 on the inside facing surface of thebody wall 123 may be configured to engage with an upper surface of thepiston 180 when thepiston 180 is depressed. Theindexing stop 190 may prevent thepiston 180 from returning to the position shown inFIGS. 6 and 7 . Theindexing stop 190 may be configured as a protruding structure, as shown inFIG. 3B , or a recessed structure, as shown inFIG. 3C . Alternatively, or in addition, the second indexing stop may be configured to engage with theplunger cover 175, preventing theplunger cover 175 from traveling too far within thebody 120 of the dispensingcap 170. -
FIGS. 8 through 11 depict another exemplary embodiment of a dispensingcap 200 including aspects of the invention. As illustrated, the dispensingcap 200 includes abody 220 having astorage compartment 224 therein and a mountingstructure 230, and aplunger 270. Thestorage compartment 224 enables temporary storage of asupplement 50 for use in conjunction with abeverage 60. Theplunger 270 may include aplunger cover 275 and apiston 280. - The mounting
structure 230 may have an inside facing surface 232 which may be substantially smooth. The distal perimeter of the mountingstructure 230 may includeannular engagement structures 234. Theengagement structures 234 may be configured to mate with the rim of a beverage container, for example to “snap-on” to a beverage container. - The
wall 223 of thebody 220 may increase in thickness at anannular transition location 295. The increase in thickness of thewall 223 reduces the inside diameter of thebody 220. With theplunger 270 in a depressed position, as shown inFIG. 10 , theplunger cover 275 may be prevented from traveling farther down thebody 220 by reduction in inside diameter. Alternatively, asecond indexing stop 295 may prevent theplunger cover 275 from traveling father down thebody 220. Afirst indexing stop 290 is also depicted inFIG. 10 . - In use, the original cap of the
beverage container 65 may be removed, and the dispensingcap beverage container 65. A user may press on theplunger cover piston piston floor storage compartment supplement 50 to mix with thebeverage 60. Thepiston floor beverage 60. - Although the foregoing description contains many specifics, these should not be construed as limiting the scope of the invention, but merely as providing illustrations of some embodiments of the invention.
