Insulating wrapper sleeve for container

Abstract

An insulating wrapper sleeve for a container is provided. The wrapper sleeve can include an interior insulating layer and an exterior base layer. The insulating layer can include disruptions in the form of corrugations, embossments, debossments or apertures in various configurations along the surface of the insulating layer. To form the sleeve, the insulating layer is secured to the base layer and the disruptions create air gaps between the insulating layer and the base layer. The ends of the sleeve can then be secured together and adapted to receive a container so that the interior portion of the insulating layer contacts and rests against the sidewall of a container. The air gaps created within the sleeve provide for increased thermal characteristics of the container and sleeve combination.

What is claimed is: 
     
         1 . An insulating wrapper sleeve for a container, said sleeve comprising:
 an insulating layer having a plurality of edges defining a perimeter; and   an base layer having a plurality of edges defining a perimeter;   wherein said insulating layer is affixed to said base layer so that said plurality of edges of said insulating layer cannot freely migrate relative to said base layer.   
     
     
         2 . The insulating wrapper sleeve of  claim 1 , wherein said insulating layer has a plurality of disruptions defined therein, said disruptions creating a plurality of air gaps between said insulating layer and said base layer when said insulating layer and said base layer are affixed. 
     
     
         3 . The insulating wrapper sleeve of  claim 2 , wherein said disruptions are configured in the fonts of corrugations. 
     
     
         4 . The insulating wrapper sleeve of  claim 2 , wherein said disruptions are configured in the form of embossments. 
     
     
         5 . The insulating wrapper sleeve of  claim 2 , wherein said disruptions form a plurality of raised portions of said insulating layer and a plurality of contacting portions of said insulating layer. 
     
     
         6 . The insulating wrapper sleeve of  claim 2 , wherein said insulating layer is affixed to said base layer only at contacting portions of said insulating layer. 
     
     
         7 . The insulating wrapper sleeve of  claim 1 , wherein said insulating layer is affixed to said base layer only along said plurality of edges of said insulating layer. 
     
     
         8 . The insulating wrapper sleeve of  claim 1 , wherein said insulating layer and said base layer are approximately the same size so that said plurality of edges of said insulating layer are substantially aligned with said plurality of edges of said base layer. 
     
     
         9 . The insulating wrapper sleeve of  claim 1 , wherein said insulating layer is smaller in size that said base layer so that said base layer contains an outer perimeter edge region when said insulating layer is affixed to said base layer. 
     
     
         10 . The insulating wrapper sleeve of  claim 1 , wherein an outer surface of said insulating layer contacts an inner surface of said base layer when said insulating layer and said base layer are affixed together, and wherein said outer surface is affixed to said inner surface by an adhesive layer applied to the entirety of said outer surface contacting said inner surface. 
     
     
         11 . The insulating wrapper sleeve of  claim 1 , wherein said sleeve includes a first edge lateral end and a second lateral end and wherein said lateral edges are connected together to form a generally frustoconical sleeve. 
     
     
         12 . A container comprising an inner sidewall and an outer sleeve, said outer sleeve comprising:
 an insulating layer having a plurality of edges; and   a base layer having a plurality of edges;   wherein said insulating layer is secured to said base layer so that said plurality of edges said insulating layer are not free to migrate relative to said base layer, and wherein said outer sleeve is secured to said inner sidewall of said container.   
     
     
         13 . The container of  claim 12 , wherein said insulating layer is secured to said base layer along said plurality of edges of said insulating layer. 
     
     
         14 . The container of  claim 12 , wherein an entire outer surface of said insulating layer is secured to said base layer. 
     
     
         15 . The container of  claim 12 , wherein said insulating layer is configured with a plurality of disruptions creating air gaps between said insulating layer and said base layer and between said insulating layer and said inner sidewall of said container. 
     
     
         16 . The container of  claim 15 , wherein said disruptions further form a plurality of raised portions not in contact with said base layer and a plurality of contacting portions in contact with said base layer. 
     
     
         17 . The container of  claim 16 , wherein said insulating layer is secured to said base layer along the plurality of contacting portions. 
     
     
         18 . The container of  claim 15 , wherein said disruptions are in the form of corrugations. 
     
     
         19 . The container of  claim 15 , wherein said disruptions are in the form of embossments. 
     
     
         20 . An insulating wrapper sleeve configured to placement around a sidewall of a container, said wrapper sleeve comprising:
 an insulating layer defined by a plurality of edges, said insulating layer comprising:
 a plurality of corrugations extending in a generally vertical direction between two of said plurality of edges of said insulating layer; 
 a plurality of raised portions formed by said corrugations; and 
 a plurality of contacting portions formed by said corrugations; and 
   a base layer defined by a plurality of edges;   wherein all of said contacting portions of said insulating layer are affixed to said base layer so that said plurality of edges of said insulating layer are not free to migrate relative to said base layer.
