Embossed double wall cup

Abstract

A multi-walled container comprising a receptacle, and outer sleeve, and an intermediate space defined therebetween for insulating the container is provided. The receptacle includes a bottom wall and a circumferential sidewall, the receptacle sidewall including at least one outwardly projecting embossment spaced below an upper edge of the receptacle. The outer sleeve has a circumferential sidewall which may include at least one inwardly projecting debossment. The at least one outwardly projecting embossment contacts and engages the at least one inwardly projecting debossment of the receptacle to define an intermediate insulating layer between the receptacle sidewall and outer sleeve sidewall and secure the outer sleeve to the receptacle.

What is claimed is: 
     
         1 . A multi-walled container, the container comprising:
 a receptacle constructed of a paperboard material having a bottom wall and a circumferential sidewall, the receptacle sidewall including a plurality of vertically-extending, outwardly projecting embossments;   an outer sleeve having a circumferential sidewall, wherein a portion of the outer sleeve is positioned against the outwardly projecting embossments of the receptacle; and   a plurality of spaces defined between the receptacle sidewall and the outer sleeve sidewall.   
     
     
         2 . The container of  claim 1 , wherein the outwardly projecting embossments extend at least a majority of the height of the receptacle. 
     
     
         3 . The container of  claim 1 , wherein each outwardly projecting embossment has a height and a width, wherein the height of at least one of the embossments is at least four times greater than the width of such embossment. 
     
     
         4 . The container of  claim 1 , wherein the outwardly projecting embossments are vertically extending ribs. 
     
     
         5 . The container of  claim 1 , the outer sleeve further comprising at least one inwardly projecting debossment. 
     
     
         6 . The container of  claim 5 , wherein a portion of the at least one inwardly projecting debossment of the outer sleeve is positioned against the at least one of the outwardly projecting embossments of the receptacle. 
     
     
         7 . The container of  claim 5 , wherein the at least one inwardly projecting debossment is a continuous debossment extending circumferentially around substantially an entire perimeter of the sleeve sidewall. 
     
     
         8 . The container of  claim 5 , wherein the at least one inwardly projecting debossment recesses inward from an adjacent portion of the sleeve sidewall a distance of between about 0.02 inches and about 0.3 inches. 
     
     
         9 . The container of  claim 1 , wherein at least one of the outwardly projecting embossments protrudes from an adjacent portion of the receptacle sidewall a distance of between about 0.02 inches and about 0.3 inches. 
     
     
         10 . The container of  claim 1 , wherein the sleeve is constructed of paperboard material. 
     
     
         11 . A multi-walled container, the container comprising:
 a receptacle constructed of a paperboard material having a bottom wall and a circumferential sidewall, the receptacle sidewall including at least one vertically-extending, outwardly projecting embossment;   an outer sleeve having a circumferential sidewall, the outer sleeve sidewall including at least one inwardly projecting debossment;   wherein a portion of the at least one inwardly projecting debossment of the outer sleeve is positioned against the at least one outwardly projecting embossment of the receptacle; and   at least one void space defined between the receptacle sidewall and the outer sleeve sidewall.   
     
     
         12 . The container of  claim 11 , wherein the at least one outwardly projecting embossment vertically extends at least a majority of the height of the receptacle. 
     
     
         13 . The container of  claim 11 , wherein a height of the at least one outwardly projecting embossment is at least four times greater than a width of the at least one outwardly projecting embossment. 
     
     
         14 . The container of  claim 11 , wherein the at least one outwardly projecting embossment is a vertically extending rib. 
     
     
         15 . The container of  claim 11 , wherein the at least one inwardly projecting debossment is a continuous debossment extending circumferentially around substantially an entire perimeter of the sleeve sidewall. 
     
     
         16 . The container of  claim 11 , wherein the sleeve is constructed of paperboard material. 
     
     
         17 . The container of  claim 11 , wherein the at least one void space comprises an air gap. 
     
     
         18 . A multi-walled container, the container comprising:
 a receptacle constructed of a paperboard material having a bottom wall and a circumferential sidewall, the receptacle sidewall including a plurality of vertically-extending, outwardly projecting embossments;   an outer sleeve having a circumferential sidewall, the outer sleeve sidewall including at least one inwardly projecting debossment;   wherein a portion of the at least one inwardly projecting debossment is positioned against at least one of the plurality of outwardly projecting embossments; and   a plurality of air gaps defined between the receptacle sidewall and the outer sleeve sidewall.   
     
     
         19 . The container of  claim 18 , wherein the plurality of outwardly projecting embossments extend at least a majority of the height of the receptacle. 
     
     
         20 . The container of  claim 18 , the plurality of outwardly projecting embossments having a height and width, wherein the height of each embossment is at least four times greater than the width of each embossment.
