Multi-walled container with mechanically locking outer sleeve

Abstract

A multi-walled container comprising a receptacle, an outer sleeve, and an intermediate space defined therebetween for insulating the container is provided. The receptacle includes a bottom wall and 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 including an inwardly projecting upper lip at the top end thereof. The inwardly projecting upper lip is positioned above and engages the at least one outwardly projecting embossment of the receptacle to define an intermediate space between the receptacle sidewall and outer sleeve sidewall and couple the outer sleeve to the receptacle.

What is claimed is: 
     
         1 . A multi-walled container, the container comprising:
 a receptacle having a bottom wall and circumferential sidewall, the receptacle sidewall including at least one outwardly projecting embossment spaced below an upper edge of the receptacle;   an outer sleeve having a circumferential sidewall including an inwardly projecting upper lip at the top end thereof; and   a space defined between the receptacle sidewall and the outer sleeve sidewall;   wherein the inwardly projecting upper lip of the outer sleeve is positioned above and engages the at least one outwardly projecting embossment of the receptacle.   
     
     
         2 . The container of  claim 1 , wherein the at least one outwardly projecting embossment is a continuous embossment extending circumferentially around an entire perimeter of the receptacle sidewall. 
     
     
         3 . The container of  claim 1 , wherein the at least one outwardly projecting embossment comprises a plurality of spaced apart embossments formed around at least a portion of a perimeter of the receptacle sidewall. 
     
     
         4 . The container of  claim 1 , where the receptacle sidewall comprises a first outwardly projecting embossment and a second outwardly projecting embossment located above the first outwardly projecting embossment. 
     
     
         5 . The container of  claim 4 , wherein the inwardly projecting upper lip of the outer sleeve is positioned between the first outwardly projecting embossment and second outwardly projecting embossment. 
     
     
         6 . The container of  claim 1 , wherein both the receptacle and the sleeve are constructed of paperboard material. 
     
     
         7 . The container of  claim 1 , wherein the space is an air gap. 
     
     
         8 . The container of  claim 1  further comprising an outwardly rolled upper lip at the top edge thereof. 
     
     
         9 . The container of  claim 8 , the outer sleeve further comprising at least one outwardly projecting embossment positioned below the inwardly projecting upper lip, wherein the at least one outwardly projecting embossment of the outer sleeve is positioned above and engages with the receptacle upper lip of a second container when the container is nested within the second container. 
     
     
         10 . The container of  claim 9 , wherein the at least one outer sleeve outwardly projecting embossment is a continuous embossment extending circumferentially around the entire perimeter of the outer sleeve sidewall. 
     
     
         11 . The container of  claim 9 , wherein the at least one outer sleeve outwardly projecting embossment comprises a plurality of spaced apart embossments formed around at least a portion of a perimeter of the outer sleeve sidewall. 
     
     
         12 . 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 outwardly projecting embossment spaced below an outwardly rolled upper lip at the top edge thereof;   an outer sleeve constructed of a paperboard material having a circumferential sidewall including an inwardly projecting upper lip at the top end thereof; and   a space defined between the receptacle sidewall and the outer sleeve sidewall;   wherein the inwardly projecting upper lip of the outer sleeve is positioned above and engages the at least one outwardly projecting embossment of the receptacle.   
     
     
         13 . The container of  claim 12 , wherein the at least one outwardly projecting embossment is a continuous embossment extending circumferentially around the entire perimeter of the receptacle sidewall. 
     
     
         14 . The container of  claim 12 , wherein the receptacle sidewall comprises a first outwardly projecting embossment and a second outwardly projecting embossment located above the first outwardly projecting embossment. 
     
     
         15 . The container of  claim 12 , wherein the inwardly projecting upper lip of the outer sleeve is positioned between the first outwardly projecting embossment and second outwardly projecting embossment. 
     
     
         16 . The container of  claim 12 , wherein the space is an air gap. 
     
     
         17 . The container of  claim 12  further comprising an outwardly rolled upper lip at the top edge thereof. 
     
     
         18 . A multi-walled container, the container comprising:
 a receptacle having a bottom wall and circumferential sidewall, the receptacle sidewall including a first outwardly projecting embossment and a second outwardly projecting embossment located above the first outwardly projecting embossment, both embossments being spaced below an upper edge of the receptacle;   an outer sleeve having a circumferential sidewall including an inwardly projecting upper lip at the top end thereof; and   a space defined between the receptacle sidewall and the outer sleeve sidewall;   wherein the inwardly projecting upper lip of the outer sleeve is positioned above and engages the at least one outwardly projecting embossment of the receptacle.   
     
     
         19 . The container of  claim 18 , wherein the first outwardly projecting embossment and second outwardly projecting embossment are each a continuous embossment extending circumferentially around the entire perimeter of the receptacle sidewall. 
     
     
         20 . The container of  claim 18 , wherein at least one of the first outwardly projecting embossment and second outwardly projecting embossment comprises a plurality of spaced apart embossments formed around at least a portion of a perimeter of the receptacle sidewall. 
     
     
         21 . The container of  claim 18 , wherein the inwardly projecting upper lip of the outer sleeve is positioned between the first outwardly projecting embossment and second outwardly projecting embossment. 
     
     
         22 . The container of  claim 18 , wherein both the receptacle and the sleeve are constructed of paperboard material.
