Abstract

A receptacle for maintaining the temperature of its contents. The body of the receptacle is constructed of a triple-walled, dual chamber enclosure. This dual chamber enclosure is comprised of an inner chamber and an adjacent outer chamber occupied, respectively, by a gel and a gaseous matter. Temperature regulating properties of the gel contained within the inner chamber are insulated by the adjacent outer chamber, permitting the temperature regulating properties of the gel to last for a longer period of time.

Claims

exact text as granted — not AI-modified
1 . A multi-chamber receptacle, comprising: 
 an inner receptacle member having a first rim and defining a cavity for receiving a substance;    a middle receptacle member having a second rim and shaped complementary to the inner receptacle member for nesting with the inner receptacle member;    an outer receptacle member having a third rim and shaped complementary to the middle receptacle member for nesting with the middle receptacle member;    wherein the inner, middle and outer receptacle members are nested to form a first chamber between the inner receptacle member and the middle receptacle member and a second chamber between the middle receptacle member and the outer receptacle member, and wherein the first, second and third rims are joined to seal the first chamber and the second chamber;    a gel disposed within the sealed first chamber; and    an insulator disposed within the sealed second chamber.    
   
   
       2 . The multi-chamber receptacle of  claim 1 , wherein the insulator is a gas.  
   
   
       3 . The multi-chamber receptacle of  claim 2 , wherein the gas is selected from the group consisting of ambient air, nitrogen and carbon dioxide.  
   
   
       4 . The multi-chamber receptacle of  claim 1 , wherein the gel is a thermal gel.  
   
   
       5 . The multi-chamber receptacle of  claim 1 , wherein the gel is a cooling gel.  
   
   
       6 . The multi-chamber receptacle of  claim 1 , wherein the gel is a heating gel.  
   
   
       7 . The multi-chamber receptacle of  claim 1 , wherein the gel is an insulating gel.  
   
   
       8 . The multi-chamber receptacle of  claim 1 , wherein the gel is a high specific heat gel.  
   
   
       9 . The multi-chamber receptacle of  claim 1 , wherein the first rim, the second rim and the third rim are joined by welding them together.  
   
   
       10 . The multi-chamber receptacle of  claim 1 , wherein the first rim, the second rim and the third rim are joined by gluing them together.  
   
   
       11 . The multi-chamber receptacle of  claim 1 , wherein the multi-chamber receptacle comprises a material selected from the group consisting of a metal, a polymer and combinations thereof.  
   
   
       12 . The multi-chamber receptacle of  claim 1 , wherein the inner receptacle member, the middle receptacle member and the outer receptacle member are stainless steel.  
   
   
       13 . The multi-chamber receptacle of  claim 1 , wherein the multi-chamber receptacle comprises a bowl.  
   
   
       14 . The multi-chamber receptacle of  claim 1 , wherein the multi-chamber receptacle comprises a casserole dish.  
   
   
       15 . The multi-chamber receptacle of  claim 1 , wherein the multi-chamber receptacle comprises a platter.  
   
   
       16 . The multi-chamber receptacle of  claim 1 , wherein the multi-chamber receptacle comprises a pan.  
   
   
       17 . The multi-chamber receptacle of  claim 1 , wherein the multi-chamber receptacle comprises a pitcher.  
   
   
       18 . The multi-chamber receptacle of  claim 1 , wherein the multi-chamber receptacle comprises a drinking cup.  
   
   
       19 . The multi-chamber receptacle of  claim 1 , wherein the multi-chamber receptacle comprises an ice bucket.  
   
   
       20 . The multi-chamber receptacle of  claim 1 , further comprising a lid to seal the cavity of the multi-chamber receptacle.  
   
   
       21 . A multi-chamber receptacle, comprising: 
 an inner receptacle member having a first rim and defining a cavity for receiving a substance;    a middle receptacle member having a second rim and shaped complementary to the inner receptacle member for nesting with the inner receptacle member;    an outer receptacle member having a third rim and shaped complementary to the middle receptacle member for nesting with the middle receptacle member;    wherein the inner, middle and outer receptacle members are nested to form a first chamber between the inner receptacle member and the middle receptacle member and a second chamber between the middle receptacle member and the outer receptacle member, and wherein the first, second and third rims are joined to seal the first chamber and the second chamber;    an oil disposed within the sealed first chamber; and    an insulator disposed within the sealed second chamber.    
   
   
       22 . The multi-chamber receptacle of  claim 21 , wherein the insulator is a gas.  
   
   
       23 . The multi-chamber receptacle of  claim 21 , wherein the gas is selected from the group consisting of ambient air, nitrogen and carbon dioxide.  
   
   
       24 . The multi-chamber receptacle of  claim 21 , wherein the first rim, the second rim and the third rim are joined by welding them together.  
   
   
       25 . The multi-chamber receptacle of  claim 21 , wherein the first rim, the second rim and the third rim are joined by gluing them together.  
   
   
       26 . The multi-chamber receptacle of  claim 21 , wherein the multi-chamber receptacle comprises a material selected from the group consisting of a metal, a polymer and combinations thereof.  
   
   
       27 . The multi-chamber receptacle of  claim 21 , wherein the inner receptacle member, the middle receptacle member and the outer receptacle member are stainless steel.
