Insulated Drinking Container

Abstract

An insulated drinking container having a sidewall structure comprising an inner wall and an outer wall, wherein the inner wall comprises a ceramic material and wherein a gap is provided between the inner wall and the outer wall and an insulating material that is placed in the gap. A sidewall structure for an insulated drinking container having an inner wall comprising a ceramic material, an outer wall, wherein the inner wall and the outer wall are formed such that there is a gap between the inner wall and the outer wall and an insulating material that is inserted in the gap.

What is claimed is: 
     
         1 . An insulated drinking container, comprising:
 a sidewall structure comprising an inner wall and an outer wall, wherein the inner wall comprises a ceramic material and wherein a gap is provided between the inner wall and the outer wall; and   an insulating material that is placed in the gap.   
     
     
         2 . The insulated drinking container of  claim 1 , wherein the insulating material is one of a quilted insulation panel, a semi-quilted insulation panel, a pourable microporous powder, a foam material or a polyurethane blowing agent. 
     
     
         3 . The insulated drinking container of  claim 1 , wherein the outer wall comprises one of ceramic, stainless steel, glass, plastic, or a composite material. 
     
     
         4 . The insulated drinking container of  claim 3 , wherein the inner wall and outer wall comprise different materials. 
     
     
         5 . The insulated drinking container of  claim 1 , further comprising:
 a bottom portion that seals the insulating material in the air gap.   
     
     
         6 . The insulated drinking container of  claim 5 , wherein the bottom portion is coupled to the inner wall. 
     
     
         7 . The insulated drinking container of  claim 1 , wherein the inner wall and the outer wall meet and wherein a further single wall structure extends past the location where the inner wall and outer wall meet, the further single wall structure forming an upper rim of the insulated drinking container. 
     
     
         8 . The insulated drinking container of  claim 1 , wherein the inner wall and the outer wall meet to form an upper rim of the insulated drinking container. 
     
     
         9 . The insulated drinking container of  claim 1 , wherein the insulating material is glued to the inner wall. 
     
     
         10 . The insulated drinking container of  claim 1 , further comprising:
 a lid to seal an upper portion of the insulated drinking container.   
     
     
         11 . A sidewall structure for an insulated drinking container, comprising:
 a inner wall comprising a ceramic material;   an outer wall, wherein the inner wall and the outer wall are formed such that there is a gap between the inner wall and the outer wall; and   an insulating material that is inserted in the gap.   
     
     
         12 . The sidewall structure of  claim 11 , wherein the insulating material is one of a quilted insulation panel, a semi-quilted insulation panel, a pourable microporous powder, a foam material or a polyurethane blowing agent. 
     
     
         13 . The sidewall structure of  claim 11 , wherein the outer wall comprises one of ceramic, stainless steel, glass, plastic, or a composite material. 
     
     
         14 . The sidewall structure of  claim 11 , wherein the inner wall and the outer wall meet at a location and wherein a further single wall structure extends past the location where the inner wall and outer wall meet, the further single wall structure forming an upper rim of the insulated drinking container. 
     
     
         15 . The sidewall structure of  claim 11 , wherein the inner wall and the outer wall meet to form an upper rim of the insulated drinking container. 
     
     
         16 . The sidewall structure of  claim 11 , wherein the insulating material is initially inserted as a liquid that expands into a foam insulation after insertion. 
     
     
         17 . The sidewall structure of  claim 11 , wherein the insulating material is a powder that is enclosed in a flexible material, wherein the flexible material including the powder is inserted into the gap.
