Reusable beverage containers are increasingly popular as an environmentally-friendly alternative to single-use containers, such as plastic bottles. Consumers may fill and refill a reusable beverage container with a beverage for consumption throughout the day, such as by filling the container with water at a water fountain. However, a consumer may wish to drink more than one type of beverage throughout the day. The consumer may benefit from the option to fill their container with water or to prepare a flavored beverage. Many reusable beverage containers are simply used to store a beverage and do not provide additional functionality, such as the ability to dispense beverage ingredients from a beverage-ingredient cartridge. Thus, a container that may facilitate preparing a beverage from beverage ingredients (e.g., in addition to water) may be desirable to allow consumers to quickly and easily prepare such a beverage using a beverage container.
In some embodiments described herein, a reusable beverage container includes a vessel having an upper end defining an upper opening, and a cap removably securable to the upper end of the vessel to seal the upper opening. The cap includes a lower shell and an upper shell that are removably securable to one another so as to define an interior volume for receiving and completely enclosing a beverage-ingredient cartridge. The lower shell defines a lower opening such that when the cap is secured to the vessel, the interior volume of the cap is connected with the interior volume of vessel. The lower shell further includes a cartridge opener extending from the lower shell that is configured to engage the beverage-ingredient cartridge so as to cause a beverage ingredient stored within the cartridge to be dispensed from the cartridge into the vessel when a force is applied to press the cartridge onto the cartridge opener.
A reusable beverage container 100 includes a vessel 110 and a cap 180, as shown in
Neck portion 130 of vessel 110 may be removably securable to body portion 120, as shown in
In some embodiments, neck portion 130 may further include a lip 137 extending upwardly from upper end 133 of neck portion 130 and which defines upper opening 134, as shown in
Neck portion 130 may be removed from body portion 120, for example, to facilitate filling of body portion 120 (e.g., with a liquid and/or ice) or to facilitate washing vessel 110, as opening 125 of body portion 120 has a diameter that is larger than a diameter of upper opening 134 of neck portion 130. When neck portion 130 is secured to body portion 120, a consumer may drink from upper opening 134 of neck portion 130 which has a smaller diameter than opening 125 of body portion 120 and which may be better suited for sipping a beverage from vessel 110. However, it is understood that a beverage may alternatively be filled into vessel 110 via upper opening 134 of neck portion 130, and neck portion 130 need not be removed from base portion 120 for filling vessel 110. It is further understood that a consumer may drink from opening 125 of body portion 120 with neck portion 130 removed from body portion 120, if desired.
In some embodiments, vessel 110 is insulated so as to inhibit heat transfer into or out of vessel 110. Vessel 110 may have a double-walled construction to provide insulation. Further, in some embodiments, vessel 110 may be formed from a metal, such as stainless steel. An interior surface of vessel 110 may be coated, such as with a coating of copper, to provide further insulation for vessel 110. In some embodiments, neck portion 130 is formed from the same material as body portion 120, and thus may be formed of a metal, such as stainless steel. However, in alternate embodiments, neck portion 130 may be formed from a polymer or plastic, such as acrylonitrile butadiene styrene (ABS) or a polyamide, among other suitable materials.
A cap 180 may be removably secured to vessel 110 of reusable beverage container 100 so as to seal upper opening 134 at upper end 133 of neck portion 130. Cap 180 may be removed from vessel 110 to allow a consumer to drink a beverage stored within vessel 110. Cap 180 may be hollow so as to define an interior volume configured to receive and completely enclose a beverage-ingredient cartridge 500. Cap 180 may be shaped similarly to a shape of a beverage-ingredient cartridge 500. In some embodiments, cap 180 may have a spherical or spheroid shape so as to receive a beverage-ingredient cartridge 500 having a spherical or spheroid shape. As cap 180 is configured to receive cartridge 500, cap 180 may be somewhat larger than cartridge 500 so as to receive cartridge 500 within cap 180. However, in some embodiments, cap 180 may have any of various other shapes, and may be shaped as a cube, a rectangular prism, a pyramid, or a hemisphere, among various other shapes. Cap 180 may be formed from the same material as neck portion 130 of vessel 110. In some embodiments, cap 180 may be formed from a polymer or plastic, such as acrylonitrile butadiene styrene (ABS) or a polyamide, among other suitable materials.
When cap 180 is secured to vessel 110, cap 180 seals upper opening 134 of vessel 110 and cap 180 may be used as a handle or grip for carrying reusable beverage container 100. Thus, a consumer may carry beverage container 100 by cap 180 rather than by grasping body portion 120 of vessel 110. This may help to prevent heat transfer from the consumer's hand to the beverage, and may provide consumer with a more secure grip on reusable beverage container 100. Further, in embodiments in which cap 180 has a spherical or spheroid configuration, cap 180 may be particularly well-suited for being grasped in the palm of a consumer's hand with the consumer's fingers wrapped around the cap 180 to provide the consumer with comfortable and secure grip of reusable beverage container 100.
In embodiments in which cap 180 has a generally spherical or spheroid shape, cap 180 is connected such that a lower end of sphere is connected to vessel 110 to provide beverage container 100 with an appearance of a sphere or ball on top of vessel 110. In some embodiments—whether or not cap 180 has a spherical or spheroid shape—cap 180 may have a maximum diameter DM (e.g., in embodiments where cap 180 has a spherical or spheroid shape DM may be a maximum exterior diameter of such spherical or spheroid shape), cap 180 may be connected to vessel 110 at a portion of cap 180 having a diameter of 0.1DM to 0.7DM, or 0.2DM to 0.6DM. Thus, a consumer may place their fingers around the relatively narrow lower end of cap 180 at which cap 180 meets vessel 110, and the relatively larger higher portion in their hand (e.g., in embodiments where cap 180 has a spherical or spheroid shape, the user may grasp the spherical or spheroid “ball” shape in a palm of their hand). In some embodiments, maximum diameter of cap 180 may be 1 inch to 3 inches, or 1.25 inches to 2.75 inches, or 1.5 inches to 2.5 inches.
In some embodiments, cap 180 can have a maximum diameter that is greater than a diameter of upper opening 134 and less than a maximum diameter of body portion 120 of vessel 110. In some embodiments, upper opening 134 may have a diameter that is at least 0.5 inches to a maximum that is equal to a diameter of vessel 110, which may be for example, 2.5 inches, 3 inches, or 3.5 inches. In some embodiments, maximum diameter of cap 180 may be 10% to 600% greater than a diameter of upper opening 134 of vessel 110, or may be 50% to 300% greater than a diameter of upper opening 134 of vessel 110, or may be 75% to 250% greater than a diameter of upper opening 134 of vessel 110. In this way, cap 180 widens from its lower end connected to vessel 110 at upper opening 134 toward a mid-portion of cap 180 having the maximum diameter, and, in some embodiments, diameter of cap 180 decreases or tapers from mid-portion toward an upper end 205 of cap 180. Thus, beverage container 100 is narrowest at upper opening 134 as neck portion 130 of vessel 110 tapers from lower end 131 towards upper end 133 and upper opening 134, and lower shell 190 of cap 180 widens from lower end 191 to upper end 193, creating a narrowed region to be grasped by the consumer. In embodiments in which cap 180 is a spherical shape as described above, cap 180 may be easily grasped by a consumer by grasping cap 180 in a palm of consumer's hand such that the consumer's fingers wrap around cap 180 and are positioned adjacent lower end of cap 180 having a reduced diameter.
In some embodiments, cap 180 includes a lower shell 190 and an upper shell 200 that are removably securable to one another, as shown in
In some embodiments, lower shell 190 may be connected to upper shell 200 by a snap-fit connection. However, lower shell 190 may be secured to upper shell 200 via press fit or interference fit, among other types of removable connection known in the art. In some embodiments, lower shell 190 may be connected to upper shell 200 via a connection ring 150, as best shown in
In some embodiments, upper shell 200 of cap 180 may be secured to lower shell 190 by a twist-lock connection, as shown in
In some embodiments, a seal ring 156 may be positioned around a circumference of connection ring 150 as shown in
Cap 180 may be removably secured to vessel 110 by lower shell 190. Lower shell 190 includes a body 192 having a lower end 191 and an upper end 193. Lower shell 190 may widen from lower end 191 toward upper end 193. Lower shell 190 may define a lower opening 194 at lower end 191 of body 192. Thus, when lower shell 190 is secured to vessel 110, an interior volume 185 of cap 180 is connected to (e.g., in fluid communication with) an interior volume of vessel 110 via lower opening 194. Lower shell 190 may include a neck 198 at lower end 191 that defines opening 194. Neck 198 may include threading 199 on an exterior surface of neck 198 for engaging with threading 138 on an interior surface of upper end 133 of vessel 110, such as threading 138 of lip 137 of neck portion 130. It is understood, however, that threading may alternatively be provided on an interior surface of neck 198 of lower shell 190 and on an exterior surface of upper end 133 of vessel 110.
In some embodiments, lower shell 190 may further include a recess 197 surrounding neck 198 for receiving an upper end of vessel 110, as shown in
When cap 180 is secured to vessel 110, lip 137 of neck portion 130 is inserted into recess 197 of cap 180 such that lip 137 may be partially or fully obscured by lower shell 190, and in turn neck 198 of lower shell 190 is inserted into upper opening 134 of vessel 110. In this way, when cap 180 is connected to vessel 110, beverage container 100 has a smooth and unitary appearance with no connecting structures visible to a consumer (see
Lower shell 190 further includes a cartridge opener 195 configured to facilitate dispensing of beverage ingredients from beverage-ingredient cartridge 500, as best shown in
In some embodiments, cartridge opener 195 extends inwardly from a lower end 191 of lower shell 190 toward an upper end 193 of lower shell 190. Cartridge opener 195 may be formed as one or more projections 221 spaced around lower opening 194, as best shown in
In some embodiments, cartridge opener 195 may instead be formed as a single projection extending above opening 194 of lower shell 190. In such embodiments, cartridge opener 195 may have a pointed upper end for contacting cartridge 500, and cartridge opener 195 may be shaped, for example, as a pyramid, a post, or a spike. In some embodiments, cartridge opener 195 may have a cross-shaped transverse cross sectional area, and may have a pointed upper end.
In some embodiments, lower shell 190 may further include an inner seal 210. When cartridge 500 is positioned in lower shell 190 for dispensing beverage ingredients, cartridge 500 presses against inner seal 210 so as to form a seal that prevents liquid in vessel 110 from entering an interior volume of cap 180 outside of a cartridge 500 through lower opening 194 (e.g., flowing along an exterior of cartridge 500). Inner seal 210 is positioned on an interior surface 196 of lower shell 190. Inner seal 210 may have an annular shape that contours to interior surface 196, and thus may have a generally hemispherical shape. Further, inner seal 210 is positioned on interior surface 196 and extends around cartridge opener 195 and lower opening 194 of lower shell 190. Inner seal 210 may be formed from a flexible and/or compressible material with good sealing properties, such as, for example, silicone or rubber. Inner seal 210 may be co-molded or over-molded with lower shell 190. In some embodiments, inner seal 210 may be formed separately from lower shell 190 and assembled as part of cap 180. In such embodiments, inner seal 210 may be disposed within lower shell 190 without any further attachment to lower shell 190 (e.g., so that it can be easily removed, for example, to be washed), or may be secured to lower shell 190 by glue, adhesives, bonding, welding, among other fastening methods.
While reusable beverage container 100 may receive a cap 180 as described herein for dispensing beverage ingredients from a beverage-ingredient cartridge 500, beverage container 100 may be configured to receive alternate types of caps 180. A consumer may wish to use different caps at different times. For example, a cap that simply seals vessel 110 without providing the functionality of dispensing beverage-ingredients from a cartridge 500 may be desired where the consumer wishes to save space or when the consumer wishes to use the vessel 110 to simply store water or other pre-made beverages. Further, a consumer may prefer a cap having a particular shape, geometry, or size for use in carrying the reusable beverage container 100, or which provides a desired aesthetic appearance.
Similarly, cap 180 may be removably securable to other beverage containers, such as existing plastic bottles. In some embodiments, for example, cap 180 may be securable to a single-use plastic bottle. Many single-use plastic beverage bottles have a common standard diameter and thread configuration. Cap 180 can be formed to mate with one of these common standard diameter and thread configurations, or may be used with a threaded adapter that allows cap 180 to sealably attach to one of these common standard diameter and thread configurations. Thus, cap 180 can be used to allow a consumer to dispense beverage ingredients from a cartridge 500 into any of various bottles that are shaped and sized to receive cap 180. Further, cap 180 may be sized and shaped so as to engage with the upper end, e.g., the mouth, of existing plastic bottles and containers, with or without an adapter.
An exemplary method of operating reusable beverage container 100 to prepare a beverage using a beverage-ingredient cartridge 500 is shown in
Cap 180 may be removably secured to upper end 133 of neck portion 130 of vessel 110 for sealing upper opening 134 until the consumer wishes to drink the beverage within vessel 110. Cap 180 may be secured to upper end 133 of neck portion 130 by engaging threading 199 on neck 198 of lower shell 190 of cap 180 (e.g., exterior threading, as shown) with threading 138 on upper end 133 of neck portion 130 (e.g., interior threading, as shown). Cap 180 provides a liquid-tight seal and when threading 138 on upper end 133 of neck portion 130 of vessel 110 is engaged with threading 199 on lower shell 190 of cap 180, and further recess 197 may include a seal ring 158 therein that contacts upper end 133 of neck portion 130 when neck portion 130 is inserted into recess 197. Further, the arrangement of threading 138 of neck portion 130 as interior threading, and of threading 199 of cap 180 as exterior threading helps allow more direct access from cap 180 through upper end 133 of neck portion 130 and into vessel 110, since it can provide a smooth transition into the interior (e.g., for beverage ingredients to traverse) without interference from connection structures (e.g., threads).
The consumer may select a beverage-ingredient cartridge 500 that stores one or more beverage ingredients 300, 400, and the beverage ingredients may be in powder or liquid form. Cartridge 500 may have a spherical or spheroid shape. Cartridge 500 may include an opening covered by a seal 510, such as a plastic film or a displaceable component, such that beverage ingredients 300, 400 can be released from cartridge 500 upon application of a force to seal 510 of cartridge 500.
In order to prepare a beverage using reusable beverage container 100 and a beverage-ingredient cartridge 500, upper shell 200 of cap 180 can be removed from lower shell 190, with lower shell 190 still secured to neck portion 130 of vessel 110. Beverage-ingredient cartridge 500 may be positioned with its seal 510 facing downward, such that seal 510 of cartridge 500 is in contact with cartridge opener 195 of lower shell 190, as shown in
Upper shell 200 may be placed on top of cartridge 500 and a force may be applied along a longitudinal axis of cartridge 500 and of reusable beverage container 100 so as to push cartridge 500 into cartridge opener 195 in a direction toward vessel 110. As the force is applied to upper shell 200 and upper shell 200 moves toward engagement with lower shell 190, upper shell 200 in turn applies a force to cartridge 500 to open cartridge 500 to dispense the beverage ingredients. When upper shell 200 reaches lower shell 190, upper shell 200 connects to lower shell 190, engaging with lower shell 190 by, for example, snap-fit, such that beverage-ingredient cartridge 500 is sealed within cap 180, as shown in
As mentioned above, while upper shell 200 is in the process of being closed (e.g., engaging with lower shell 190) with a cartridge 500 positioned against cartridge opener 195 of lower shell 190, cartridge opener 195 pushes against seal 510 of cartridge 500, and upon sufficient application of force, cartridge opener 195 punctures or enters cartridge 500 and causes beverage ingredients 300, 400 to be dispensed from cartridge 500 (see
The consumer may shake reusable beverage container 100 so as to mix beverage ingredients 300, 400 and liquid 600 to form the beverage. Because beverage-ingredient cartridge 500 is enclosed within cap 180, cartridge 500 is in contact with inner seal 210 of lower shell 190 so as to form a seal that prevents liquid from passing from vessel 110 through lower opening 194 of lower shell 190 and into cap 180 along an exterior surface of cartridge 500. After mixing the beverage ingredients and the liquid, cap 180 may be removed from vessel 110 so that a consumer may drink the beverage from vessel 110. Cap 180 serves to store the used beverage-ingredient cartridge 500 such that cap 180 may continue to be used to seal upper opening 134 of vessel 110, and cartridge 500 can be stored in cap 180 until a consumer wishes to remove and dispose of cartridge 500 (e.g., in a recycling receptacle). The ability to store a used or spent cartridge 500 within cap 180 may be beneficial so that the consumer does not have to separately carry or store the used cartridge 500, especially in circumstances in which a receptacle for appropriately disposing of the cartridge may not be readily available at the location where the consumer prepares the beverage.
