Beverage Container Interface for Flush Valve Cap Engagement

Abstract

Provided is a thermally insulated sleeve to hold a beverage, the thermally insulated sleeve comprising: a substantially circular tubular member extending between three and eight inches along a central axis, the tubular member defining an external surface to be gripped by a user and an internal surface to at least partially envelope a beverage container and thermally insulate the beverage container, the internal surface having an diameter of between two and six inches, a distal end of the tubular member being open to receive a beverage container upon the beverage container being slid into the tubular member; and a beverage cap interface coupled to the tubular member at an end of the tubular member opposite the distal end, wherein the beverage cap interface comprises a receptacle shaped to interface with a flush valve cap of a urinal.

What is claimed is: 
     
         1 . A thermally insulated sleeve to hold a beverage, the thermally insulated sleeve comprising:
 a substantially circular tubular member extending between three and eight inches along a central axis, the tubular member defining an external surface to be gripped by a user and an internal surface to at least partially envelope a beverage container and thermally insulate the beverage container, the internal surface having an diameter of between two and six inches, a distal end of the tubular member being open to receive a beverage container upon the beverage container being slid into the tubular member; and   a beverage cap interface coupled to the tubular member at an end of the tubular member opposite the distal end, wherein the beverage cap interface comprises a receptacle shaped to interface with a flush valve cap of a urinal or toilet.   
     
     
         2 . The sleeve of  claim 1 , wherein the beverage cap interface is configured to resiliently deform upon the beverage cap interface being mated to the flush valve cap. 
     
     
         3 . The sleeve of  claim 1 , wherein the beverage cap interface defines a substantially hexagonal cylindrical volume. 
     
     
         4 . The sleeve of  claim 1 , wherein the beverage cap interface defines a substantially cylindrical volume with a base having 24 sides. 
     
     
         5 . The sleeve of  claim 1 , wherein the beverage cap interface is configured to clip onto the top of a urinal. 
     
     
         6 . The sleeve of  claim 1 , wherein the beverage cap interface is integrally formed with the tubular member. 
     
     
         7 . The sleeve of  claim 6 , wherein the beverage cap interface is integrally formed with the tubular member in an injection molding process within a single mold. 
     
     
         8 . The sleeve of  claim 1 , wherein the tubular member comprises neoprene. 
     
     
         9 . The sleeve of  claim 1 , wherein the tubular member comprises ethylene-vinyl acetate. 
     
     
         10 . The sleeve of  claim 1 , wherein the tubular member comprises a closed-cell foam. 
     
     
         11 . The sleeve of  claim 1 , wherein the tubular member is formed by injection molding a foam in a mold with the beverage cap interface previously disposed therein, the beverage cap interface being made of a different material from the tubular member and injection molded before the tubular member. 
     
     
         12 . The sleeve of  claim 1 , wherein the beverage cap interface comprises:
 an aperture to allow condensation liquid to escape.   
     
     
         13 . The sleeve of  claim 1 , wherein the beverage cap interface comprises:
 substantially planar sidewalls having respective normal vectors that are non-orthogonal to a central axis of the tubular member.   
     
     
         14 . The sleeve of  claim 1 , wherein the beverage cap interface comprises:
 an interior volume defining a generally octagonal cylindrical shape.   
     
     
         15 . The sleeve of  claim 1 , wherein the beverage cap interface comprises:
 an interior volume having a depth of between 0.2 and 1 inches.   
     
     
         16 . The sleeve of  claim 1 , wherein the beverage cap interface comprises: 
     
     
         17 . The sleeve of  claim 1 , wherein the beverage cap interface comprises:
 a chamfered edge.   
     
     
         18 . The sleeve of  claim 1 , wherein the beverage cap interface comprises:
 at least three resilient members shaped and positioned to flex away from one another upon the flush valve cap of the urinal being inserted into the beverage cap interface.   
     
     
         19 . The sleeve of  claim 1 , wherein the beverage cap interface comprises:
 means for securing a beverage to the flush valve cap.   
     
     
         20 . The sleeve of  claim 1 , comprising:
 a beverage configured to be inserted into the sleeve.
