INGREDIENT DISPENSING CAP FOR BEVERAGE CONTAINER
A beverage ingredient dispenser can include a seal assembly configured to form spillproof seals with the inner surface (I.D.) of a beverage container opening. Additionally, a beverage ingredient dispenser can include a beverage ingredient reservoir containing a beverage ingredient to be mixed with another ingredient for creating a mixed beverage. For example, the beverage ingredient dispenser can include a dried powdered, tablet, or liquid ingredient to be mixed with water contained in a water bottle. The dispenser can also include a sealing mechanism configured to generate spillproof seals with a plurality of different sizes of beverage containers. The dispenser can also include an anchoring mechanism configured to enhance an anchoring of the dispenser to a beverage container.
The inventions disclosed herein relate to ingredient dispensing devices, for example, devices that can be connected to an opening of a beverage container for facilitating release of beverage ingredients stored therein into the beverage container for later consumption.
Description of the Related ArtPresently, there are thousands of beverage products widely available to the consuming public. The vast majority, if not all, of these beverages are made by mixing dry or concentrated ingredients with water. Alongside these beverages, various brands of bottled water in variety of differently sized bottles are also widely marketed.
Many retailers normally cannot sell all of the different beverages and waters currently offered by beverage manufacturers. The practical reality of the large amount of shelf space required for selling beverages effectively limits the number of different beverages many retailers can offer for sale at any one time. Thus, most retailers must choose a limited number of beverages of the many available, they wish to sell through their establishment.
Recently, beverage ingredient dispensing devices have become available. Such dispensing devices include a reservoir containing dried, compressed and liquid beverage ingredients and a threaded water bottle engagement collar. The threaded collar can be screwed to the top a water bottle with the same thread configuration. The reservoir can then be pierced so as to allow the ingredient to be discharged from the reservoir and mixed with the water in the water bottle. Some versions of this type of cap include drink-through spouts which allow a user to drink the mixed beverage through the dispensing device itself.
SUMMARY OF THE INVENTIONSAn aspect of at least one of the inventions disclosed here includes the realization that some beverage ingredient dispensing caps, such as those described above, suffer from several drawbacks. For example, one aspect of at least one of the inventions disclosed herein includes the realization that some known beverage ingredient dispensing caps, which rely on a threaded engagement with the opening of a water bottle, can only be used on one size water bottle. However, there are a range of different sizes of water bottles with differently sized openings presently on the market, many of which have different threads, including different thread sizes, and different thread pitches. Thus, a dispensing cap provided with a threaded collar designed for engagement with one water bottle will not work on most other water bottles. Such beverage ingredient dispensing caps can leave a user without the ability to connect the cap to the bottles that may be available at a given time.
Thus, in accordance with some embodiments, a beverage ingredient dispenser can include a seal assembly configured to seal against inner surfaces of the openings. As such, the beverage ingredient dispenser can avoid the need for threaded engagement surfaces, such as those used on the prior art devices described above, thereby avoiding unnecessary costs. For example, threaded engagement surfaces such as those provided on the caps of water bottles add a significant amount of cost to the manufacturing of such caps from plastic. Such caps are typically manufactured with a molding process and after an initial stiffening of the material molded with internal threads, the molded part must be unscrewed from the mold itself. Thus the timing and procedures necessary for successfully molding such a part presents significant cost to the manufacturing of such a component. Thus, a beverage ingredient dispenser that includes a seal assembly configured to seal against the inner surfaces of the openings of a beverage container can avoid the cost associated with the formation of internal threads for engaging the external threads typically found on many beverage containers.
Further, in some embodiments, a beverage ingredient dispense can include a seal assembly configured to seal against the inner surfaces of a range of sizes of beverage container openings. For example, in some embodiments, the seal assembly is configured to seal with a range of sizes of inner diameters of beverage container necks over a range of at least about ⅜ of one inch. This can be particularly convenient for users because a significant number of different water bottles have inner diameters within a range of about ⅜ of an inch, for example, about 0.80 inches to about 1¼ inches. Further, in some embodiments, the seal assembly can be configured to seal with a range of sizes of inner diameters of beverage container necks over a range of at least about ⅝th of one inch, for example, about 0.63 inches. This can also be convenient for users because a significant number of different water bottles have inner diameters within a range of about 0.63 inches, for example, from about 1.14 inches to about 1.77 inches, a range of sizes larger than those noted above, which can include some bottles commonly used as infant feeding bottles or “baby bottles”. Some of the beverage containers commonly available include inner diameters of about 1.3 inches and 1.61 inches, which also fall within this range.
Further embodiments can provide further advantages by including seal assemblies that can seal with a range of sizes of inner diameters of ¾ of one inch to about 1 and ¾ of one inch, for example, from 0.8 inches to about 1.77 inches. Thus, such beverage ingredient dispensers can be used with a wide variety of different, widely available water bottles.
Another aspect of at least one of the inventions disclosed herein includes the realization that some known beverage ingredient dispensers, whether they include powdered, liquid or tablet ingredients, can require an unnecessarily complicated installation procedure. For example, some known beverage ingredient dispensers, such as those described above which include a threaded collar for threaded engagement with a water bottle, require a user to first rotate the dispenser so as to threadedly engage the dispenser with a water bottle. Then after the dispenser has been threadedly engaged, the user must press an actuator to dispense the beverage ingredient into the liquid in the water bottle.
An aspect of at least one of the inventions disclosed herein includes the realization that beverage ingredient dispensers can be configured with a sealing and dispensing mechanism that provides the dual functions of sealing to an opening of a primary beverage container, and also dispensing a stored ingredient into the liquid, using a single motion. For example, a beverage ingredient dispenser can include a reservoir, a sealing mechanism, and an actuator. The actuator can be connected to both the dispenser and the sealing mechanism so as to cause the sealing mechanism to enhance a seal between the dispenser and the primary beverage container, as well as actuating the dispenser so as to dispense the beverage ingredient into the liquid in the primary container. For example, in some embodiments, the actuator can be configured for a single actuating movement such that a user can simply place the dispenser onto the opening of a water bottle, then press straight down, thereby actuating the sealing mechanism and dispenser with movement in a single direction. Alternatively, in some embodiments, a beverage ingredient dispenser can include a rotating actuator also connected to both the sealing mechanism and a dispenser so as to actuate the sealing mechanism and the dispenser with a single rotational movement.
Another aspect of at least one of the inventions disclosed herein includes the realization that some known beverage ingredient dispensers include dispensing actuators that result in interference with the discharge of beverage ingredient into the primary container, the mixing of the liquid in the primary container, as well as the discharge of the mixed beverage through the dispenser, for example, in the context of drink-through dispensers. More specifically, some known beverage ingredient dispensers include a frangible wall, such as a layer of foil. The dispensing mechanism on this type of device includes a rod with a piercing end, such as a sharpened point, configured to pierce the foil when the user pushes the rod downwardly. However, an aspect of at least one of the inventions disclosed herein includes the realization that merely piercing the foil often leaves pieces of the foil in a position interfering with the movement of the beverage ingredient out of the reservoir as well as movement of liquid into the reservoir for mixing purposes. For example, even though a piercing rod may initially cut and push pieces of the foil outwardly away from the reservoir, the foil remains free to bend back and forth and thus can interfere with the movement of the beverage ingredient out of the reservoir as well as liquid from the primary container into the reservoir.
Thus, in accordance with some embodiments, a beverage ingredient dispenser includes a piercing member and a frangible wall deflecting member. Thus, for example, a piercing member of the beverage ingredient dispenser can be actuated so as to pierce a frangible wall, such as a layer of foil, and then further deflect the foil away from a center of the bottom wall of the dispenser. As such, the frangible wall, such as the layer of foil, can be pushed farther out of the way of the beverage ingredient and thus interfere less with movement of the beverage ingredient out of the reservoir and liquid into the reservoir. In some embodiments, the deflection member includes a ring or collar disposed adjacent to an inside wall of the reservoir and positioned so as to fold a frangible wall toward a perpendicular orientation relative to the orientation of the frangible wall before piercing. Other configurations can also be used.
Another aspect of at least one of the inventions disclosed herein includes the realization that some beverage ingredient dispensers, such as those described above, can fail to discharge the desired amount of beverage ingredients from the associated reservoir because the piercing rod is smooth-sided. For example, in such known beverage ingredient dispensing devices, dried beverage ingredients can become more viscous (more resistant to movement) over time, for example, by caking. Thus, when the piercing rod is moved downwardly through the beverage ingredient so as to pierce the foil, some of the beverage ingredient can remain lodged in the reservoir.
Thus, in accordance with some embodiments, a beverage ingredient dispenser can include a dispensing element configured for axial movement relative to the ingredient reservoir. Additionally, the dispensing element can include at least one laterally extending surface extending into the ingredient reservoir. Thus, when the dispenser is actuated, for example, moved axially relative to the ingredient chamber, the laterally extending surface can assist movement of the beverage ingredient axially through the reservoir and thereby better overcome the potential effects of caking of a dry beverage ingredient. Additionally, the laterally extending surface can also, by way of moving a greater amount of ingredient out of the reservoir upon actuation, help push open a frangible wall through the interaction of the ingredient with the opened wall.
Another aspect of at least one of the inventions disclosed herein includes the realization that certain known beverage ingredient dispensers suffer from breakage and leaks due to the structural configuration of a bellows. More specifically, some known beverage ingredient dispensers include bellows attached to an actuator, for example, those designs described, with reference to
Thus, in accordance with some embodiments, a beverage ingredient dispenser includes an actuator connected to a beverage ingredient reservoir with a circular bellows member.
Another aspect of at least one of the inventions disclosed herein includes the realization that a sealing mechanism can achieve enhanced performance with regard to the ability to seal to a variety of different sizes of inner diameters of beverage container openings by including moveable members configured to increase the size of the contact patch between a resilient sealing member and the inner diameter of the beverage container opening. For example, in some embodiments, a beverage dispenser can include a ratcheting mechanism configured to modulate movement of sealing mechanism components during insertion of the dispenser into the opening of a beverage container opening, so as to press against the seal member and thereby increase a contact patch between the seal member and the inner surface. Ratcheting mechanisms can be configured to engage through axial movement or radial movement. Further, in some examples, ratcheting mechanisms can be used in conjunction with cooperating wedge shaped members.
Another aspect of at least one of the inventions disclosed herein includes the realization that a beverage ingredient dispenser can include retention members configured to extend into a primary beverage container for engagement with a portion of a neck of a beverage container to resist inadvertent withdrawal of the dispenser from the container. For example, a beverage ingredient dispenser can include extendable arms configured to extend into a beverage container, and radially outwardly into a space within the beverage container beneath the neck of the beverage container. As such, a beverage ingredient container can better retain a desired engaged position with the opening of the beverage container, and thereby resist unintended removal of the beverage dispenser.
Another aspect of at least one of the inventions disclosed herein includes the realization that some forms of beverage ingredients are sold in containers which can be inconvenient or difficult to open and dispense into a beverage container, such as a bottle of water. For example, some beverage ingredients can come in the form of a “blister pack”. Such blister packs typically contain a frame portion, a frangible portion, and a compressible portion. A beverage ingredient can be stored between the compressible portion and the frangible portion such that the beverage ingredient can be discharged by a user by pressing on the compressible portion such that a beverage ingredient is pushed through the frangible portion, causing the frangible portion to break and release the ingredients therethrough.
When using such a blister pack for discharging ingredients into a beverage container, such as a bottle of water, users can find and encounter difficulty in releasing the full contents of the blister pack into the beverage container. For example, wind can interfere with the process of discharging the ingredient into a beverage container, for example, by blowing some of the ingredients away from the opening of the container at the moment the frangible portion is broken. As such, a user may fail to mix all of the ingredient with the beverage in the container. This problem can be more undesirable in the context of unintended discharge of strong coloring agents (typical in high anti-oxidant nutrients) or volatile bubbling additives. Additionally, a user may find it awkward to hold beverage container and at the same time rupture the frangible portion of the blister pack while holding the beverage container securely, thereby accidently spilling some of the beverage and/or ingredient out of the bottle. Further, some of the ingredient may stick or adhere to the inside of the compressible portion or frangible portion of the blister pack found thereby preventing all of the ingredient from reaching the beverage in the beverage container.
An aspect of at least one of the inventions disclosed here includes the realization that a beverage ingredient dispenser can include blister pack alignment and sealing features and functionality for connection to a beverage container so as to facilitate a more accurate and complete discharge of the beverage ingredient from a blister pack into a beverage container. For example, in some embodiments, beverage ingredient dispenser can include a seal assembly configured to seal to an opening of a beverage container, a blister pack receiver portion ends an aperture aligned with the opening of the beverage container. As such, a user can attach the dispenser to a beverage container with the aperture aligned with the opening of the container. Additionally, user can insert a blister pack into the blister pack receiving portion such that the frangible portion of the blister pack is aligned with the aperture. As such, a user can compress the compressible portion of the blister pack so as to compress the ingredient against the frangible wall, thereby breaking the frangible wall and allowing the ingredient to flow into the opening of the beverage container.
In some embodiments, the blister pack receiving portion can be configured to form a leak reducing seal with a portion of the bottom surface of the blister pack surrounding the frangible portion. For example, the blister pack receiving portion can include a surface complimentary to the bottom surface of a blister pack and with a conforming material such that when a user presses the blister pack against the blister pack receiving portion, a spill proof seal can be formed against the blister pack receiving portion and the bottom surface of the blister pack. With such a sealing feature, a user can hold the water bottle while pressing down on the blister pack and shake the water bottle, thereby more thoroughly mix the ingredient within the blister pack with the beverage contained in the beverage container.
Another aspect of at least one of the inventions disclosed herein includes the realization that beverage ingredient dispensers with blister pack related features and functionality can include blister pack receiving portions configured to simplify the process of insertion of the blister pack into the receiving portion, for example, so as to more easily achieve alignment of the blister pack in the blister pack receiving portion. In some embodiments, blister pack portions can be provided with a circular shape around at least a portion of the outer periphery of the blister pack. As such, the blister pack receiving portion can include a complimentary, partly circular shape. Thus, a blister pack can be inserted with the partly circular periphery pressed against the partly circularly shaped portion of the blister pack receiving portion and thus be more easily alignable with the blister pack receiving portion.
Thus, in some embodiments, a blister pack assembly can include a plurality of individual blister packs connected together, for example, with frangible portions. Each of the blister pack members can include an outer periphery, at least having a circular shape around at least approximately 180 degrees around the periphery thereof. Further, in some embodiments, the blister pack members can be circular around substantially the entire parameter thereof. Further, in some embodiments, the blister pack members include frangible portions at four locations spaced around the circular periphery, at which the blister pack can be connected to four other blister pack members, forming a blister pack assembly. The frangible portions can present minor discontinuities and/or imperfections along the outer circular periphery of the blister pack members.
In other embodiments, the outer periphery of blister pack members can include other shapes, for example, but without limitation, other nonrectangular shapes including semi hexagonal, hexagonal, semi octagonal, octagonal, oval, semi oval, or other curved and/or faceted shapes or combinations thereof.
Another aspect of at least one of the inventions disclosed herein includes the realization that some designs for ingredient dispensers can be improved by including a drink through valve mounted to an ingredient reservoir which can be mounted for piercing movement relative to a piercing element. In such configurations, the piercing element can be coupled to a beverage container opening. In some embodiments, the piercing element can be connected to a sealing assembly configured to seal to a range of sized of openings of beverage containers, including ranges of different sizes of threaded openings typically provided on water bottles.
This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
The inventions disclosed herein are described in the context of beverage ingredient dispensers that can be attached to beverage containers because they have utility in this context. However, the inventions disclosed herein can be used in other contexts as well, including but without limitation, dispensers for other types of ingredients, attachments to other types of devices, other food and beverage related contexts, pharmaceutical and Nutraceutical mixing and/or delivery devices, as well as other industrial and commercial non- food contexts, such as chemical organic/inorganics additives, plasticizers, coloring agents, etc.
Optionally, at least some of the embodiments disclosed herein can be configured to be used with a primary container, such as a beverage container. In some environments of use, such a primary container can be a beverage or water bottle that is commercially available. It has been determined that a substantial portion of the commercially available beverage bottles, and in particular water bottles, have openings that fall within a well-defined range of sizes.
For example, with reference to
The illustrated beverage containers 10, 12 have similar shapes. For example, the water bottle 10 includes an opening 20 having an inner surface 22 which is generally cylindrical in shape. The inner surface 22 thus can define an inner diameter. The opening 20 includes a shaft length 24 that extends from the upper end 26 of the opening 22 to a lower end 28. At the lower end 28, the water bottle 10 tapers outwardly along a tapering wall 30 out to the maximum diameter portion 32 which forms the bulk of the volumetric capacity of the bottle 10. At the transition between the lower end 28 and the tapering wall 30, the water bottle 10 includes a shoulder 34.
Similarly, the water bottle 12 includes an opening 40 having an upper end 42 and an inner surface 44. The opening 40 has a lower end 46 transitioning to a tapering wall 48 at a shoulder 50. The tapering wall 48 connects to the main portion 52 of the bottle 12.
The water bottle 10 illustrated
Additionally, the shaft length 24 of the bottle 10 has a length of 0.38 inches and the shaft length of the bottle 12 is approximately 0.775 inches. It has been determined that a significant portion of the presently commercially available water bottles have shaft lengths within the range of approximately 0.38 inches to 0.775 inches, for example, approximately 0.4 inches to approximately 0.8 inches. Thus, the range of shaft lengths in a portion of the presently commercially available water bottles is 0.395 inches or approximately 0.4 inches.
Typically, the water bottles 10, 12, and other water bottles falling within the range of sizes of the water bottles 10, 12 described above, include threads on the outer surfaces of the openings 20, 40, for threaded engagement with caps. In order to ensure properly oriented positive engagement with such threads, a device to be connected to such threads would need to have threads of a corresponding size and pitch. Thus, it is difficult to design one attachment device which can positively engage in a spill proof manner, water bottles having different thread sizes or pitches.
With reference to
In some embodiments, the beverage ingredient dispenser 100 includes a seal assembly 120 that is configured to generate at least spillproof seals with both water bottle 10 and water bottle 12, as well as one or more additional sizes of water bottles having intermediate sizes between the size of water bottle 10 and water bottle 12. For example, another water bottle (not shown) can have an opening with an inner diameter between 0.85 inches and 1.25 inches. Additionally, the seal assembly 120 can be configured to generate at least spillproof seals with different ranges of bottle sizes, optionally, inclusive of and/or greater than inner diameters of 1.25 inches such as 38 mm or about 1.5 inches or inclusive of and/or less than 0.85 inches, or other diameters.
In some embodiments, the seal assembly 120 can be configured to form spillproof seals with the inner surfaces of beverage containers, such as the inner surfaces 22, 44 of the water bottles 10, 12. As such, the seal assembly 120 is more likely to generate spillproof seals with different water bottles having different thread patterns on the outer diameter.
For example, seal assembly 120 can be configured to form a spillproof seal with the inner diameter of primary containers having any inner diameter, but with different thread patterns because such different thread patterns would not interfere with forming seals with the inner surfaces of the openings of such bottles. Additionally, such inner surfaces of beverage containers, which can be inwardly facing, can cooperate with attached devices to provide an anchoring function, for anchoring the attached device to the beverage container. Thus in some embodiments, the seal assembly 120 can be configured to form a spill proof seal and to achieve an anchoring engagement with the inner surface with sufficient anchoring to prevent the dispenser 100 from being unintentionally removed from the beverage container, for example, when the dispenser is subjected to small axial forces in a direction away from the beverage container.
For example, the seal assembly 120 can be configured to form a spill proof seal and to achieve an anchoring engagement with the inner surface with sufficient anchoring to prevent the dispenser 100 from being removed from the associated bottle when a user pulls axially on a drink-through valve (described below). In some embodiments, the seal assembly 120 can be configured to generate an anchoring engagement with the inner surface of the beverage container that is sufficiently strong to support the entire weight of the beverage container to which it is attached, and optionally, a beverage contained therein, if the dispenser 100 is grasped by a user and lifted off of a table. For example, in some embodiments where the beverage container contains approximately 1 L of a beverage having about the same density of water, the anchoring engagement between the seal assembly 120 and the inner surface of the beverage container can be sufficiently strong to resist a kilogram-force of about 1 kilogram generated by the weight of the beverage container and the 1 L of the beverage contained therein.
Additionally, the dispenser 100 can include an additional anchoring device configured to engage a portion of the beverage container 10, 12 not in contact with the seal assembly 120, with additional anchoring to further resist the dispenser 100 from being unintentionally removed from the beverage container 10, 12, for example, when the dispenser 100 is subjected to small axial forces in a direction away from the beverage container 10, 12. In some embodiments, the combination of the anchoring engagement generated by the seal assembly 120 and such an additional anchoring device can generate an engagement with additional strength for resisting inadvertent removal of the dispenser 100 from the associated bottle, as described above. Optionally, in some embodiments, the additional anchoring device can generate further anchoring engagement sufficient to resist forces greater than the total weight of the beverage container and a beverage contained therein.
The seal assembly 120 can have various different configurations. For example, the seal mechanism 120 can comprise an assembly including multiple sealing surfaces at least one configured to be sealable against the inner surface of the opening 20 of bottle 10 and at least one other configured to be sealable against the inner surface 44 of bottle 12.
Optionally, the beverage ingredient dispenser 100 can include a dispensing mechanism 160 configured to cause the discharge of the beverage ingredient contained in the reservoir 110 and into a liquid contained within a water bottle 10, 12 to which the beverage ingredient dispenser 100 is attached. For example, the dispenser 100 can include a frangible lower wall 111 on the reservoir 110 and the dispensing mechanism can be in the form of a moveable piercing member disposed within the reservoir 110. Alternatively, the dispensing mechanism 160 can be mounted in a fixed position relative to the seal assembly 120 and the reservoir 110 can be mounted to be moveable relative to the seal assembly 120. In such configurations, the movement of the reservoir 110 can cause the frangible lower wall to be pressed against the piercing member, thereby opening the reservoir 160 for discharge of an ingredient container therein.
Optionally, the beverage ingredient dispenser 100 can include an actuator 190 configured to trigger operation of the dispenser mechanism 160. In some embodiments, the actuator 190 can also be integrated with a drink-through mechanism configured to allow a user to discharge liquid from the associated beverage container 10, 12, through the beverage ingredient dispenser 100, and outwardly, for example, for consumption.
With reference to
Additionally, in some embodiments, the seal assembly 120A can be configured to expand the seal assembly 120A to both of the inner diameters of the inner surfaces 22, 44 and exert sufficient pressure to achieve a spillproof seal with both inner surfaces 22, 44. Additionally, optionally, the seal assembly 120A can be configured to expand the seal assembly 120A to the inner diameters of both the inner surfaces 22, 44 and exert sufficient pressure to achieve anchoring of the dispenser 100A to both of the bottles 10, 12.
For example, in some embodiments, the seal assembly 120A can include a seal member 124A and an expansion device 125A. As such, the expansion mechanism 125A can expand the seal member 124A in the direction of arrow E. The expansion mechanism 125A can be any type of expansion mechanism, manually or passively activated, electric, pneumatic, hydraulic, mechanical or other types of expansion mechanisms. The expansion mechanism can be configured to generate the desired forces.

For example, the seal assembly 120B can include a seal member 124B. The seal member 124B can include upper end having an outer dimension 126B and a lower end having an outer dimension of 127B. In some embodiments, the outer dimension 126B is larger than the largest bottle to which the dispenser 100B is designed to be attached. For example, in some embodiments, the outer dimension 126B can be greater than 1.25 inches.
On the other hand, the outer dimension 127B can be smaller than the smallest size bottle 10 to which the dispenser 100B is designed to be attached. For example, the outer dimension 127B can be less than about 0.85 inches.
In some embodiments, the seal member 124B can be conical in shape. However, other configurations can also be used.

Other heights can also be used. For example, in some embodiments, the seal assembly 120B can be configured to generate the contact patch 132B of at least one-tenth of one inch when the dispenser 100B is attached, in the manner illustrated in

Optionally, the dispensing mechanism 160C can include at least one laterally extending surface 170C extending laterally from piercing member 161C. For example, the lateral surface 170C can be configured to assist in discharging a beverage ingredient from the reservoir 110C when the piercing member 161C is moved downwardly (as viewed in
Additionally, the dispensing mechanism 160C can include a frangible wall deflecting assembly 180C. For example, the frangible wall deflecting assembly 180C can be configured to deflect separated pieces of the frangible wall 111C away from a center axis of the reservoir 110C. Such deflection, for example, can assist in preventing pieces of the broken frangible wall 111C from interfering with the flow of beverage ingredient out of the reservoir 110C or liquid from the attached container flowing into the reservoir 110C.
Optionally, the frangible wall deflecting assembly 180C can be connected to the piercing member 161C with a connection assembly 181C. For example, a connecting assembly 181C can connect the piercing member 161C with the deflecting assembly 180C such that the deflecting assembly 180C moves with the piercing member 161C. Optionally, the actuator 190C can be also connected to the piercing member 161C. Thus, for example, the actuator 190C can be configured to allow a user to press on an upper surface of the actuator 190C to thereby move the piercing member 161C in a downward direction, as viewed in

The layers 228 can have outer surfaces shaped to fit within the openings, and seal therewith, of bottles of different sizes. For example, the layer 228 can include a lower end 227A defining an outer diameter that is less than 0.85 inches. Additionally, the inner layer 228 can define an outer diameter 226A that is larger than 0.85 inches. Similarly, the outer layer 229 can include a lower end 227B defining a diameter that is less than 1.25 inches but greater than 0.85 inches. Further, the outer layer 229 can include an upper end defining an outer diameter 226B that is greater 1.25 inches.
Thus, for example, the opening of the bottle 10 can be inserted around the lower end 227 of the layer 228 and moved into a spillproof sealing engagement with the layer 228.
Similarly, as shown in
Optionally, a user can actuate the actuator 290 to actuate the dispensing mechanism 260. For example, a user can push downwardly on the actuator 290, which is connected to the dispensing mechanism. Upon downward movement, the dispensing mechanism opens the lower wall 211 of the reservoir 210, thereby allowing beverage ingredient to be released from the reservoir 210. Additionally, a user can apply the downward force to the actuator 290 to cause the movement required to seal the seal assembly 220 with the inner surface of the bottle 12. Thus, the dispenser 200 can be installed and sealed to either of the bottles 10, 12 with a single direction of movement.
