1. Field of the Invention (Technical Field)
There are typically two types of keg dispensers readily available for home use. One, in its simplest form, is a boxed refrigerator with a column setting on top. The “column”, as it is generally referred to within the beer industry, is a cylindrical tube having an outside diameter of approximately four inches and an inside diameter of approximately three inches. The column is normally disposed on top of a refrigerated housing comprising tubing that connects the keg to the spigot. The tubing also limits airflow through the column. A spigot is also attached to the column. Aside from an unsightly appearance, such a configuration also makes it difficult to adequately cool the section of tubing housed within the column. Because beer which is not properly cooled has a tendency to foam excessively when dispensed into a drinking container, such known devices are plagued with chronic foaming. To combat this problem, some high-end residential units utilize a separate blower which forces cool air directly into the column in order to minimize foaming. However, this additional hardware increases the cost of the unit, thereby preventing the average consumer from purchasing it.
The second type of dispenser is a modified refrigerator with the spigot attached directly to the door of the refrigerator. This type is not manufactured. Instead, it is typically sold as a kit to be installed by the purchaser and requires drilling into the front door of a standard residential refrigerator, thereby defacing it and possibly damaging the refrigerator, and likely voiding the manufacture's warranty. Yet another problem with this known arrangement is that average individuals lack the basic knowledge of how draft works, thus making such piecemeal kit-systems problematic. Still further, another aspect of such an arrangement, viewed by some as unfavorable, is having the spigot and drip tray protrude from the front of the refrigerator door where aside from being unsightly, could prove to be a possible hazard (i.e. snagging of clothing or injury due to bumping with force).
While there may be other arrangements for dispensing kegs, they are typically reserved for commercial use due to the high cost of the equipment, installation and high maintenance associated with running such devices; they are not conducive for use in a residential setting.
Ideally, a keg dispenser should be easy to operate and maintain with little or no issues with product loss due to foam and should be aesthetically pleasing.
2. Description of Related Art
Note that the following discussion refers to a number of publications by author(s) and year of publication, and that due to recent publication dates certain publications are not to be considered as prior art vis-a-vis the present invention. Discussion of such publications herein is given for more complete background and is not to be construed as an admission that such publications are prior art for patentability determination purposes.
U.S. Pat. No. D 469,787 to Wicker discloses a keg cooler ornamental in design where the dispenser has a cylindrically contoured front to wrap around the keg. The dispenser column, however, is still located on the top outside of the housing thus operating as a typical keg cooler with dispenser column on top of the housing.
U.S. Pat. No. D 352,296 to Westendorf illustrates a keg-shaped keg cooler. Although ornamental, the design serves no utilitarian purpose.
U.S. Pat. No. 6,502,415 to Chiusolo et al. discloses a cooling system requiring the use of water and ice circulated over conduits by agitators to keep beer from foaming. This is arrangement is only useful in an off-grid setting where conventional refrigeration is not available. U.S. Pat. No. 4,225,059 to Kappos, U.S. Pat. No. 3,865,276 to Thompson and U.S. Pat. No. 2,223,152 to Nagin, also describe methods that are useful where typical refrigeration-techniques are not available or not preferred. Both of these systems lack a refrigeration unit, thus making them unsuitable for daily residential or commercial use.
U.S. Pat. No. 7,237,390 to Nelson discloses a portable cooling unit for use during social gatherings. Although the system provides desirable results for events lasting a few days, it is not useful for routine home use, where a keg may last weeks or months before being consumed. This is because Nelson's system fails to cool the entire keg, thus causing the beer to spoil in a short time. This system also lacks the ability to conceal the spigots from the public's view.
Another issue with current keg dispensers is the shear size of the units. For the most part, they are designed to house large ½ barrel kegs, which are typically used in commercial settings. This gives the appearance of a bar or frat house to the location in which they are housed. There are also a growing number of kegs being used to distribute craft or specialty beers. These are known as slim ¼ or slim 5 gallon kegs. These smaller kegs, generally referred to as “slim kegs” are also favored by a growing sect of home brewers. There is currently no known cylindrical dispenser designed specifically for these slim kegs.
There is thus a present need for an apparatus that dispenses slim kegs or typical ½ barrel kegs while maintaining a compact size. Particularly, an apparatus which is easier to maintain and operate and which ensures proper cooling and thus avoids the foaming problems that are so prolific in known keg dispensers. There is further a need for a keg-dispensing apparatus which includes an outer-housing that is shaped to fit within the décor of a home or trendy sports bar.
An embodiment of the present invention relates to a beverage dispensing apparatus that includes a keg compartment and an upper column having one or more upper doors and a spigot that is concealed when the doors are closed. In one embodiment the keg compartment is cooled by a cooling unit. The cooling unit can operate on the principal of adiabatic cooling of a compressed refrigerant and/or include a Peltier-effect-based thermo electric cooler. In one embodiment, the keg compartment can include a door which has a drip tray disposed in an upper end thereof. The keg compartment can be disposed below the upper column. Optionally, the spigot can be disposed on a front portion of the upper column.
In one embodiment the spigot is not disposed on a top surface of the dispensing apparatus. Optionally, the upper column is not cylindrical. The upper column can have at least two different radiuses of curvature. The upper column can include two upper doors and the keg compartment can include only one door. Optionally, the upper column can include a cool air entrance opening having a cross-sectional area of at least 24 square inches within which at least a terminal portion of a line lies. The cool air entrance opening can be communicably coupled to an interior of the keg compartment and not to ambient air when a door of the keg compartment is closed and the upper doors are open. Optionally, the cool air entrance opening can be communicable with ambient air when a door of the keg compartment is open, but not when the door is closed.
In one embodiment, the spigot can be rotated about a substantially horizontal axis and/or the spigot can include a quick-couple spigot handle. Optionally, a plurality of spigots can be provided. The keg compartment can include internal dimensions which accommodate a plurality of slim kegs. Optionally, a vent can be disposed in the upper column and can be communicable with an area formed between the one or more upper doors and the upper column.
An embodiment of the present invention also relates to a beverage dispensing apparatus having a keg compartment, an upper column that includes one or more upper doors and a spigot that is concealed when the doors are closed; and the dispenser having an elongated cylindrical shape.
An embodiment of the present invention also relates to a beverage dispensing apparatus having a substantially cylindrical shape; a cooled keg compartment; a first spigot communicably coupled to a keg tap; a second spigot communicably coupled to a water source; and the spigots can be secured within a spigot bay that is formed into a portion of the substantially cylindrical shape.
An embodiment of the present invention also relates to a beverage dispensing apparatus having a keg containing compartment, and an upper column, the upper column having a spigot, wherein an outer portion of the upper column is recessed from an outer portion of the keg compartment, thereby forming a rabbeted shape.
An embodiment of the present invention relates to a method and apparatus for dispensing carbonated beverages with minimal foam by properly maintaining the temperature of the carbonated beverage within a desirable range. The apparatus preferably comprises an enhanced column which provides a greater flow of chilled air around a keg. This embodiment can also optionally provide a spigot which can be concealed from view when not in use. Another embodiment of the present invention provides a relatively small foot print, thus requiring less floor space than conventional keg dispensers. One embodiment of the present invention relates to a method and apparatus for dispensing draft beverages e.g. beer, cider, soda, ginger beer, root beer or any other beverage able to be served in through a conventional draft system.
One embodiment of the present invention comprises a keg dispenser. The keg dispenser preferably includes a cylindrical housing which is about 10 to about 24 inches in diameter, and more preferably about 13 to about 15 inches in diameter. The smaller approximate 13″ diameter housing can house a 5 gallon slim keg or a smaller keg while the larger approximate 15″ in diameter can house either a ¼ slim keg, a slim 5 gallon, or a smaller keg. Alternatively, larger diameters can be used and will provide desirable results, including the ability to house one or more full-size half kegs, 5 gallon slim kegs, and/or ¼ slim kegs. Optionally, the housing can have a single or double door wide enough and tall enough for the one or more kegs to be inserted into it. The one or more doors can optionally accommodate a keg which is in an upright position.
In one embodiment, a bottom portion of the housing preferably houses a refrigeration unit. Alternatively, the refrigeration unit can be disposed elsewhere on and/or within the housing. In one embodiment, a portion of the housing can have a rabbet incorporated into it. Optionally, the rabbet can be formed between a substantially vertical surface, upon which a spigot can be mounted, and a substantially horizontal surface, on which a drip tray can be formed.
An alternative embodiment of the present invention provides a locking mechanism, thus providing a user with the ability to hide or lock, under key, the equipment used to dispense and house a keg.
Another embodiment of the present invention provides a draft dispenser having the appearance of a water cooler with or without the ability to dispense water either from a water line or refillable water container. While using this embodiment the water dispensing nozzle can be located on the exterior of the dispenser readily available to all.
Another embodiment of the present invention provides a dispenser with the appearance of a beverage container in the shape of a can or bottle. In this embodiment, the appearance can be adapted to simulate an existing product, such as a commercially-available individual-serving-sized canned product of the dispensed beverage which is commercially available, thus building brand-recognition and product identification among consumers.
One aspect of an embodiment of the present invention provides a draft dispenser with the availability of various colors. This will prove to be useful in displaying team spirit as consuming draft beverages is sometimes associated with watching professional and collegiate sports on television.
Yet another embodiment of the present invention provides a spigot that comprises a quick-connect and quick-release mechanism (for example the mechanism can optionally be similar to those used to connect air tools to air hoses). Optionally, a locking mechanism can be incorporated and/or adapted into the quick-connect housing such that the normal placement of the handle connection for the spigot is prevented from being used.
Other objects, advantages and novel features, and further scope of applicability of the present invention will be set forth in part in the detailed description to follow, taken in conjunction with the accompanying drawings, and in part will become apparent to those skilled in the art upon examination of the following, or may be learned by practice of the invention. The objects and advantages of the invention may be realized and attained by means of the instrumentalities and combinations particularly pointed out in the appended claims.
The accompanying drawings, which are incorporated into and form a part of the specification, illustrate one or more embodiments of the present invention and, together with the description, serve to explain the principles of the invention. The drawings are only for the purpose of illustrating one or more preferred embodiments of the invention and are not to be construed as limiting the invention. For example, although the drawings illustrate only circular and oval cross-sectional-shaped housings, desirable results can also be achieved by virtually any cross-sectional shape capable of housing at least one keg of any size.

Referring now to FIGS. 1 and 2A-C, an embodiment of keg dispenser 110 is illustrated. In this embodiment, dispenser 110 preferably comprises spigot 100 attached to front portion 101 of upper column 108 of housing 102. Although numerous configurations and designs can optionally be incorporated into upper column 108, as best illustrated in
Housing 102 preferably comprises an internal void, which extends from cooling unit housing portion 107 through keg compartment 109 (see
By placing spigot 100 directly on front portion 101 of upper column 108, instead of on the end of a line which extends from housing 102, direct cooling and ventilation from cooling unit 114 (see
In one embodiment, front portion 101 of upper column 108 has a frontal diameter of about three to about four inches smaller than the outside diameter of housing 102. By providing a smaller diameter of front portion 101, which is containable within doors 103, not only is spigot 100 concealable, but drip tray 104 can thus also be contained within an upper portion of lower door 105, such that drip tray 104 resides under spigot when lower door 105 is closed. Because drip tray 104 is housed within an upper portion of door 105, when upper doors 103 are closed, not only is spigot 100 concealed, but drip tray 104 is also concealed. In an alternative embodiment, upper doors 103 can be shortened and a drip tray can be incorporated into a portion of housing 102 which wraps around the front of dispenser 110 between the upper doors and the lower door.
Optionally drip tray 104 can include a recess within which a removable drip tray can be disposed. This removable drip tray thus allows for easy cleaning and draining. In an alternative embodiment, drip tray 104 can simply comprise a recess which contains a dripped liquid. In either embodiment, a line can be connected to drip tray 104 such that liquids which are captured by drip tray 104 are led to a predetermined area, which can include a capture container, a sewer drain, and/or a heated evaporating tray.
Optionally, doors 103 can include locking mechanism 111, which aids in keeping unauthorized people, such as children, from dispensing the beverage housed therein. Lower door 105 can also optionally include locking mechanism 112. Although cooling unit 114 (see
In one embodiment, one or more vents 121 (see

With the ability to quickly connect and disconnect handle 928, a user can also optionally keep a plurality of color-coded couplers, spigots, and/or tap handles, thereby providing a manner to ensure that proper tap handles are attached to the proper spigot, particularly for those embodiments which provide a plurality of spigots.
Still another embodiment of the present invention provides a user with the ability to monitor temperature and/or remaining quantity of a beverage remaining within the keg. The temperature can be monitored via the use of one or more temperature sensors and the one or more temperature levels can be displayed on display 929 (see
Referring now to the figures generally, in one embodiment, hinges for one or more of doors 103 and/or 105 are preferably concealed when closed. In one embodiment, spigot 100 is not disposed on a top surface of dispenser the dispenser or on a top surface of upper column 101. In one embodiment, the dispenser is not cooled by, nor does it rely on ice or another substance that is cooled prior to placing it within dispenser 110. In one embodiment, upper column 101 is not cylindrical. In one embodiment, the cooling unit of the invention comprises only a single fan for circulating cooled air and does not comprise an additional blower for forcing chilled air into an area surrounding tap lines. In one embodiment, keg 106 can comprise any ready-to-drink beverage. Optionally, keg 106 can comprise any ready-drink-carbonated beverage. In one embodiment, keg 106 does not comprise a bag-in-a-box or a component thereof.
Although the invention has been described in detail with particular reference to these preferred embodiments, other embodiments can achieve the same results.
