BACKGROUND
The present invention relates to closure devices for carbonated beverage containers. The retention of the carbonation of a beverage after the container is initially open has been a problem recognized in the prior art. After the container is initially unsealed, the carbonated beverage immediately begins to loose its carbonation. Over time the beverage becomes flat even though the cap is utilized to reseal to the container. The carbonation continues to escape from the liquid into the interior of the container above the liquid.
A patent search was done and the following U.S. patent No.'s were found: U.S. Pat. No. 4,723,670 to Robinson et al which provides a hand-operated pump combined with a closure cap for sealing and pressuring the open space within a carbonated beverage container, U.S. Pat. No. 5,031,785 to Lemme which provides a combination pressure and vacuum pump for food or drink, and U.S. Pat. No. 4,899,896 to Metzger which provides a cap adapted for use in pressurizing the interior of a container for carbonated beverages.
The above mentioned patents disclose a device to re-pressurize the container to retain the carbonation within the beverage container once the container is opened. Additionally, the patents found from the search performed did not disclose a structure similar to the applicant's structure to be described herein.
SUMMARY
The object of the present invention is to provide an improved device for retaining carbonation inside beverage containers after opened for use. The present invention provides an assembly for a closure device for carbonated beverages. The device comprising a cap member manufactured to seal and adapted to engage with the mouth of the beverage container.

DETAILED SPECIFICATION
Referring to FIG. 1, there is illustrated one embodiment of the different components of the present invention, a closure device (10) for a beverage container (200). The main components of device (10) include cap member (15), connector member (35), and dispensing mechanism (100). For illustration, in FIG. 1, the main components of the closure device are disconnected.
As shown, cap member (15) has a threaded interior wall (16) adapted to engage the mouth (201) of the beverage container (200). As shown in FIG. 2, cap member (15) has interior threading which is manufactured to engage with and seal the conventional outer threading of the mouth (201) of the container (200). After the carbonated beverage is stored within container (200), cap member (15) is manufacturally sealed upon the mouth (201) of container (200) in such a manner as to maintain the required carbon dioxide pressure level within the container (200).
As depicted in FIG. 1, an inner groove (20) surrounds the outer peripheral edge of the cap member (15) forming a stud (25) within the center of the cap member (15). Stud (25) has a threaded outer wall (30) for engagement with connector member (35). The height and length of stud (25) can vary depending upon manufacturer design requirements. The illustrated embodiment further comprises connector member (35) having an internal bore (36) dimensioned to accommodate the length and the circumference of the stud (25). Bore (36) has means for circumferentially engaging the threaded outer wall (30) of stud (25).
Cap member (15) can further include sealing means (42). As shown, sealing means (42) can be an integral washer circumferentially surrounding the bottom of stud (25).
As depicted in FIG. 1, internally disposed within the top layer of bore (35) is cutting means (40). As depicted, cutting means (40) is a small triangular shape blade permanently mounted within the upper layer of bore (36). The blade extends laterally outward from the inner wall of bore (36). The blade can made of steel or another suitable material.
As shown in FIG. 2, in use, as the connector member (35) is engaged upon stud (25), a slit (45) is punctured into the outer wall of stud (25). Internal bore (36) is securely threaded onto the outer wall (30) of stud (25). Upon the final turn of threading bore (36) upon stud (25), cutting means (40) punctures a slit (45) in the outer wall of stud (25). Slit (45) provides an opening leading into outlet port (72) formed at the upper end of connector member (35). Outlet port (72) provides the means for the dispensing of the beverage from the container (200). In this embodiment, throughout the dispensing process, cap member (15) remains sealed and is never disengaged from the mouth of container (200).
Dispensing mechanism (100) is operationally connected to the top of the connector member (35). As a portion of the beverage is removed from the container through dispensing mechanism (100), the original carbonation level in the beverage container is always retained. The major advantage of the present invention is that the length of the storage time of the remaining portion of the beverage within the container does not affect the carbonation level. With the present invention, the original carbonation level is retained until the last drop of beverage is dispensed.
Referring to FIG. 1, dispensing mechanism (100) is a pouring spout (400) integrally formed upon the upper outlet port (72) of connector member (35). Pouring spout (400) extends vertically upward from connector member (35) and includes a cylindrical shape bore (403) extending upward from outlet port (72). In the illustrated embodiment, pouring spout (400) has a stepped portion (410) with a slightly smaller diameter. A valve (85) is operationally coupled to outlet port (72). Valve (85) includes a hand controlled button mechanism (80) operationally coupled to a moveable valve element (86) for opening and closing the outlet port (72) for dispensing beverage from container (200).
Referring to FIG. 1, to prevent the operation of button mechanism (80) while container (200) is in an upright storage position, locking mechanism (82) is coupled to button mechanism (80). In this embodiment locking mechanism (82) includes a groove is formed within the pouring spout (400) lying along the backside of button mechanism (80). Locking mechanism (82) further includes a ball slidably engaged within the groove. While the container (200) is in an upright storage position, the ball remains positioned behind the button mechanism (80) preventing the depression of button mechanism (80). However, when the container (200) is placed in a pouring position, the ball travels down the groove to allow the depression of button mechanism (80). Here, locking mechanism (82) provides the advantage of preventing the escape of carbonation from the container while the container is in an upright storage position. Thus, the original carbonation pressure is never loss from the container due to accidental depression of button mechanism (80).
Referring to FIG. 3, dispensing mechanism (100) can further include a lever (450) to assist in dispensing the beverage from container (200). Lever (450) is externally mounted parallel to the upper most section of pouring spout (400) above button mechanism (80). Lever (450) is aligned adjacent to and parallel with the pouring spout (400).
Referring to FIG. 4, container (200) is shown in an upright storage position while FIG. 5 shows container (200) in a pouring position. Bolt member (415), a type of actuator, is perpendicularly connected to the uppermost section of lever (450) at a position aligned directly above the button mechanism (80). The bolt member (415) protrudes outward to a desired height which is adjustable by the user. As illustrated, bolt member (415) can be adjustably screwed into the upper end of lever (450) until the desired height is obtained.
As shown in FIG. 3, handle (420) is connected to the distal end of lever (450). Handle (420) can have grooves to support the hand. In use, the user depresses handle (420) which in turns depresses the lever (450) which cause bolt member (415) to contact and depress button mechanism (80).
In some embodiments, the length of handle (420) can be adjusted. As shown in FIG. 3, rod (250) is attached to the distal end of lever (450). Handle (420) is adapted to adjustably connect to rod (250) to a desired length. In use, handle (420) is adjusted to accommodate the size of the container (i.e. 20 oz, 2, Liter, or 3 liter or etc.) as well as the size of the user's hand.
Locking mechanism (82) (illustrated in FIGS. 4 and 5) can operate in conjunction with lever (450) and handle (420). Handle (420) can only depress lever (450) while container (200) is in a pouring position, as shown in FIG. 5. Additionally, the entire lever (450) can be removable attached to the pouring spout through hooking mechanism (230). As depicted, hooking mechanism (230) is externally mounted abutting step portion (410) of pouring spout (400).
Referring to FIGS. 6 and 7, there is shown an alternative dispensing mechanism (100). In this alternative embodiment, an elongated pipe (105) interconnects the outlet port (72) of each connector member (35) to a dispensing valve (115). Elongated pipe (105) is operationally connected to dispensing valve (115) in a conventional manner. Dispensing valve (115) provides the capability of controlling the dispensing the beverage from the container.
In this embodiment, dispensing mechanism (100) can support the dispensing of beverage from a plurality of containers with each container containing a different type of carbonated beverage. To support the configuration of dispensing from a plurality of containers, stand (120) is required to securely hold at least one beverage container in an upside down position. In the illustrated embodiment in FIGS. 6 and 7, one type of stand (120) is illustrated. Stand (120) further comprises a bottom panel with a second panel perpendicularly attached near the center of the bottom panel. The second panel extends vertically upward therefrom to a set distance which allows stand (100) to fit into a cooler. Stand (120) further includes a plurality of container holders (125) mounted to the upper end of the second panel. Each container holder has the means for securely holding the upper end of the beverage container in an upside down position.
FIGS. 6 and 7 illustrate two alternative means of dispensing from a plurality of containers. In FIG. 6, each beverage container is connected to a separate dispensing valve (115) (i.e. a conventional pouring spout). However, as shown in FIG. 7, each container can be connected to a single dispensing valve (115). With this configuration, the dispensing valve (115) has a separate means (i.e. a separate button (126)) to control the dispensing of beverage from each connected container.
Additionally, the dispensing mechanism (100) can be adapted to be stored in a cooler, refrigerator or another suitable refrigeration mechanism. As shown in FIGS. 6 and 7, the height of stand (120) is adjusted to allow the stand (120) to fit in a cooler or another type of refrigeration unit.
