       BACKGROUND OF THE INVENTION 
       [0005]    The invention relates generally to the field of beverage cooling, and specifically to re-usable cold wraps containing a refrigerant gel for application to beverage cooling kegs. 
         [0006]    Beverage kegs are typically used to store and dispense large quantities of a contained beverage for consumption by a large number people. The contained beverage is most often beer, but other beverages, such as root beer, are commonly available. While many indoor keg set-ups feature a specially designed refrigerator to keep the keg and its contents cool, such devices are relatively fixed to the location of installation, and therefore may not always be available, especially at outdoor events. 
         [0007]    The prior art discloses a number of wraps and bags that may be applied to a beverage keg to keep it cool. Some simply involve an air or neoprene insulating layer, while others apply ice or a freezable refrigerant gel. Within wraps that apply a refrigerant gel, those known in the art tend to be bulky (making them difficult to store, freeze, transport, and install), tend to be fiddly to properly fit around a keg, and generally lack special access points for kegs that feature a tap at the side or bottom, rather than at the top, particularly increasingly popular disposable mini kegs. Further, many of the prior art keg wraps employing a gel employ manually inserted gel packs stored in pockets. While this type of system provides versatility, it also greatly increases the number of parts that must be separately managed and cared for. 
       SUMMARY OF THE INVENTION 
       [0008]    Accordingly, the invention is a beverage keg cooling wrap designed to easily collapse to a small, manageable package, and to easily fit and stretch around the keg using Velcro or similar fasteners. Additionally, the invention features openings for kegs that employ a side or bottom tap. 
         [0009]    Additional features and advantages of the invention will be set forth in the description which follows, and will be apparent from the description, or may be learned by practice of the invention. The foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0015]    Referring now to the invention in more detail,  FIG. 1  shows the first exemplary embodiment of the invention fitted to a standard top-tapped beverage keg. The invention, in its most basic embodiment, comprises a refrigerant wrap ( 1 ) surrounding a beverage keg ( 2 ), and held in place by Velcro strip ( 3 ); the refrigerant wrap ( 1 ) leaves the top-located tap ( 4 ) exposed. The cold wrap ( 1 ) comprises a hollow membrane of flexible and stretchable material, for example a plastic or elastic sheet, woven, or knit material. 
         [0016]      FIG. 4  shows a sectional view of the cold wrap ( 1 ). The cold wrap ( 1 ) may be formed by stitching, fusing, adhering, or otherwise affixing a pair of sheets of material ( 40 ) and ( 41 ) together along the edges; each sheet of material may comprise more than one layer. The cold wrap ( 1 ) may, optionally, be divided into chambers by fusing the opposing walls of the hollow membrane ( 40 ) and ( 41 ) together along lines to separate the chambers. The interior of the hollow membrane is filled with a refrigerant gel ( 42 ), suitable for freezing and refreezing, which may be inserted alone or inside of a flexible, impervious bladder. Many such gel materials are known in the prior art. Also optionally, the Velcro strip ( 3 ) may be of different widths to attain different amounts of gripping strength, and may be broken into sections to accommodate differently shaped kegs ( 2 ). It would further be acceptable to replace the Velcro strip ( 3 ) with an alternative fastening method, such as hooks and eyes, a lace and eyes, clasps, or buckles. 
         [0017]    Referring now to the second exemplary embodiment of  FIG. 2 , the invention is shown fitted around a beverage keg ( 2 ) features a tap ( 4 ) that protrudes from the side at the vertical center. In this configuration, the wrap ( 1 ) features an opening ( 5 ), created by short cuts made transverse to the seam held in place by the Velcro strip ( 3 ) or to a separate vertical cut, allowing for the wrap ( 1 ) to be peeled back around the tap ( 4 ). Additionally, the wrap ( 1 ) could feature a fastening means for the peeled back corners to attach to the wrap&#39;s surface, such as buttons or snaps, thereby holding the opening ( 5 ) open in a convenient and visually pleasing manner. 
         [0018]    Referring now to the third exemplary embodiment of  FIG. 3 , the invention is shown fitted around a beverage keg ( 2 ) features a tap ( 4 ) that protrudes from the side at the vertical bottom. In this configuration, the lower corners of the wrap ( 1 ) peel back around the tap ( 4 ). The corners may be located at the base of the seam held in place by the Velcro strip ( 3 ) to form an opening ( 5 ), or may optionally be located along a separate slit or cutout at the bottom of the wrap ( 1 ). Additionally, the lower corners of the wrap ( 1 ) could feature a fastening means for attachment to the wrap&#39;s surface, such as buttons or snaps, thereby holding open the opening ( 5 ) in a convenient and visually pleasing manner. 
         [0019]    While the foregoing written description of the invention enables one of ordinary skill to make and use what is presently considered to be the best mode thereof, those of ordinary skill in the art will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should, therefore, not be limited by the above described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention.
