Temperature control device for a container

Abstract

A temperature control device for a container includes a base, a projection extending from the base and temperature control substance contained within an inner chamber of the projection. The base has a bottom wall, at least one side wall, and a top wall from which the projection extends. The projection includes a side wall, a bottom wall and a top wall which together define an inner chamber in which the temperature control substance is located. Preferably, the temperature control substance is one of a phase changing material or an activated carbon. The device is configured to connect with a bottom wall opening of a container to provide temperature control to the contents located within the container.

What is claimed is: 
     
         1 . A temperature control device for a container, comprising:
 (a) A base having a bottom wall, at least one side wall, and a top wall;   (b) A projection connected with and extending from said base, said projection including a side wall, a bottom wall and a top wall defining an inner chamber, said base and projection configured for connection with a lower end opening of a drink container; and   (c) A temperature control substance contained within said inner chamber.   
     
     
         2 . The temperature control device of  claim 1 , wherein a portion of said projection side wall has a generally fluted configuration. 
     
     
         3 . The temperature control device of  claim 2 , wherein said projection has a generally conical configuration. 
     
     
         4 . The temperature control device of  claim 3 , wherein an outer surface of said base side wall contains a connection mechanism having a friction fit. 
     
     
         5 . The temperature control device of  claim 4 , wherein said connection mechanism includes a base side wall annular notch arranged to correspond with at least one side wall protuberance of a drink container lower end opening. 
     
     
         6 . The temperature control device of  claim 4 , wherein said connection mechanism includes a plurality of base side wall dimples arranged to correspond with a plurality of side wall protuberances of a drink container lower end opening. 
     
     
         7 . The temperature control device of  claim 6 , wherein said base side wall has a progressively narrowing diameter from said bottom wall to said top wall. 
     
     
         8 . The temperature control device of  claim 7 , wherein said bottom wall is planar. 
     
     
         9 . The temperature control device of  claim 8 , wherein said projection top wall has one of a convex, concave and frustoconical configuration. 
     
     
         10 . The temperature control device of  claim 1 , wherein said temperature control substance includes a phase changing material. 
     
     
         11 . The temperature control device of  claim 1 , wherein said temperature control substance includes an activated carbon, said base bottom wall including a removable seal to activate said activated carbon. 
     
     
         12 . The temperature control device of  claim 11 , wherein said base bottom wall contains at least one opening. 
     
     
         13 . The temperature control device of  claim 11 , wherein said base bottom wall includes a permeable material. 
     
     
         14 . A container, comprising:
 (a) a housing having a bottom wall containing a lower end opening, at least one side wall, and an open upper end defining a chamber;   (b) a hollow projection arranged within said chamber and integral with said bottom wall; and   (c) a temperature control device configured for connection with said container, including:
 i. a base having a bottom wall, at least one side wall, and a top wall; 
 ii. a device projection connected with and extending from said base, said device projection including a side wall, a bottom wall and a top wall defining an inner chamber, said base and said device projection being configured for connection with said hollow projection via said lower end opening; and 
 iii. a temperature control substance contained within said inner chamber. 
   
     
     
         15 . The container of  claim 14 , wherein a portion of said device projection side wall has a generally fluted configuration. 
     
     
         16 . The container of  claim 15 , wherein an outer surface of said base side wall contains an annular notch arranged to correspond with at least one side wall protuberance arranged on a surface of said hollow projection. 
     
     
         17 . The container of  claim 15 , wherein an outer surface of said base side wall contains a plurality of dimples arranged to correspond with a plurality of side wall protuberances arranged on a surface of said hollow projection. 
     
     
         18 . The container of  claim 17 , wherein said temperature control substance includes a phase changing material, said base bottom wall including a removable seal to activate said phase changing material. 
     
     
         19 . The container of  claim 18 , wherein said base bottom wall contains at least one opening. 
     
     
         20 . The container of  claim 18 , wherein said base bottom wall includes a permeable material.
