Reusable Instantaneous Beverage Cooling Device

Abstract

A cooling device for cooling beverage containers and their contents, such as, but not limited to, twelve-ounce aluminum cans. The device comprises a cylindrical body open at its top and having a bottom, where said cylindrical body includes an inner wall as well as an outer wall so as to form a plurality of compartments. In use, a beverage container is inserted into the innermost compartment surrounded by the inner wall while a solvent is added to the annular compartment between the inner and outer walls which contains a salt coolant. The dissolution of said salt in said solvent induces an endothermic chemical reaction capable of instantly cooling the beverage container as well as its contents via contact with said inner wall. Separation of the solvent from said salt coolant allows for subsequent reuse of the cooling device.

What is claimed is: 
     
         1 . A cooling device for cooling beverage containers, comprising:
 a cylindrical body open at its top and having a bottom, where said cylindrical body includes an inner wall as well as an outer wall so as to form a plurality of compartments within said cylindrical body;   a lid portion made of an insulative material having a closed top end, and a bottom end mattable with the open end of said cylindrical body;   coolant salt disposed within the annular compartment formed between said inner wall and said outer wall;   a plurality of valves for the inlet of said solvent into said annular compartment between said inner wall and said outer wall and the outlet of said solvent from said annular compartment between said inner wall and said outer wall;   insulative material disposed within said outer wall and said cylindrical body; and   whereby said cooling device cools the beverage container found within the innermost compartment via an endothermic chemical reaction, initiated by the addition of a solvent to the coolant salt found in the annular compartment between said inner wall and said outer wall and said solvent is subsequently removed for reuse of said coolant salt.   
     
     
         2 . The cooling device of  claim 1  wherein said inner wall is comprised of a conductive material, and said outer wall is made of an insulative material. 
     
     
         3 . The cooling device of  claim 1 , wherein said inner wall and outer wall comprises an adsorbent for the coolant salt. 
     
     
         4 . The cooling device of  claim 1 , wherein said insulative material disposed within said outer wall and said cylindrical body consists of a vacuum. 
     
     
         5 . The cooling device of  claim 1 , wherein said removal of solvent occurs by evaporation. 
     
     
         6 . The cooling device of  claim 1 , wherein said solvent is water.
