Self-cooling beverage container

Abstract

A self-cooling beverage container having an open base forming a compartment or chamber adapted to receive and hold a sealed base component containing a freezable liquid or gel disposed therein is disclosed.

The embodiments of the invention in which an exclusive property right or privilege is claimed are defined as follows:  
     
         1 . A self-cooling beverage container comprising: 
 a means for containing a liquid comprising a main body having a closed bottom end and an open top; said containment means further comprising a handle attached to one side of the main body and having an open-ended base member extending from the bottom end of said containment means and further defining a compartment disposed adjacent to said bottom end of said containment means; and,    a base component removeably secured to said containment means at said open-ended base member within said compartment defined by said base member; said base component comprising a hermetically sealed enclosure containing a freezable liquid or gel.    
     
     
         2 . The apparatus of  claim 1 , wherein said removable base component is threadably secured to and received by said compartment of said base member.  
     
     
         3 . The apparatus of  claim 1 , wherein said removable base component is secured within said compartment of said base member by force of friction.  
     
     
         4 . The apparatus of  claim 1 , wherein said removable base component is secured within said compartment of said base member by hook and loop material such as Velcro®.  
     
     
         5 . The apparatus of  claim 1 , wherein said open-ended base member of said containment means forms an annular extension of the main body of said containment means and has an annular internal wall defining said compartment.  
     
     
         6 . The apparatus of  claim 2 , wherein the annular internal wall of said open-ended base member further comprises internal or “female” threads.  
     
     
         7 . The apparatus of  claim 1 , wherein said hermetically sealed enclosure of said removable base component is further defined as an annular, disc-shaped, enclosure.  
     
     
         8 . The apparatus of  claim 4 , wherein said annular, disc-shaped, enclosure of said base component further comprises external or “male” threads along its perimeter wall.  
     
     
         9 . The apparatus of  claim 1 , wherein the hermetically sealed enclosure of said removable base component has external dimensions compatible with the internal dimensions of the compartment of said base member.  
     
     
         10 . The apparatus of  claim 1 , wherein said hermetically sealed enclosure of said removable base component comprises a base enclosure having two flat sides and having a perpendicular extension centrally positioned on one side of said base enclosure.  
     
     
         11 . The apparatus of  claim 10 , wherein said perpendicular extension of said base component is cylindrical.  
     
     
         12 . The apparatus of  claim 1 , wherein said containment means further comprises a chamber centrally positioned and extending perpendicularly into the main body of said containment means from its bottom end; said chamber being open at its lower end for receiving a portion of the hermetically sealed enclosure of the base component.  
     
     
         13 . The apparatus of  claim 12 , wherein said chamber is cylindrical.  
     
     
         14 . The apparatus of  claim 12 , wherein said chamber has internal dimensions compatible with the external dimensions of the portion of the base component enclosure received thereby.
