Insulated Beverage Container

Abstract

A container including a wall that defines an internal volume and an opening into the internal volume, the wall including an internal surface and an external surface, and being formed as a layered structure that includes a first layer positioned proximate the internal surface and a second layer positioned proximate the external surface, the second layer including major bosses extending into engagement with the first layer to space the second layer from the first layer.

1 . A container comprising at least one wall that defines an internal volume and comprises an internal surface and an external surface, said wall being formed as a layered structure comprising:
 a first layer positioned proximate said internal surface; and   a second layer positioned proximate said external surface, said second layer comprising a plurality of major bosses protruding into engagement with said first layer to space said second layer from said first layer.   
     
     
         2 . The container of  claim 1  wherein said second layer is embossed to define said plurality of major bosses. 
     
     
         3 . The container of  claim 1  wherein each major boss of said plurality of major bosses has a surface area ranging from about 25 to about 100 mm 2 . 
     
     
         4 . The container of  claim 1  wherein each major boss of said plurality of major bosses is spaced about 15 to about 50 mm from adjacent major bosses of said plurality of major bosses. 
     
     
         5 . The container of  claim 1  wherein said second layer has a surface area, and wherein said plurality of major bosses comprises about 2 to about 20 percent of said surface area. 
     
     
         6 . The container of  claim 1  wherein said second layer comprises about 0.5 to about 2 major bosses of said plurality of major bosses per square inch of said second layer. 
     
     
         7 . The container of  claim 1  wherein each major boss of said plurality of major bosses has a protruding depth of at least 5 points. 
     
     
         8 . The container of  claim 1  wherein each major boss of said plurality of major bosses comprises a rounded distal end. 
     
     
         9 . The container of  claim 1  wherein said second layer further comprises a plurality of minor bosses, each minor boss of said plurality of minor bosses having an average minor boss surface area, each major boss of said plurality of major bosses having an average major boss surface area, said average minor boss surface area being less than said average major boss surface area. 
     
     
         10 . The container of  claim 9  wherein said plurality of minor bosses protrude away from said first layer. 
     
     
         11 . The container of  claim 9  wherein said plurality of minor bosses protrude toward said first layer. 
     
     
         12 . The container of  claim 9  wherein each minor boss of said plurality of minor bosses has a surface area ranging from about 1 to about 25 mm 2 . 
     
     
         13 . The container of  claim 9  wherein each minor boss of said plurality of minor bosses is spaced about 1 to about 15 mm from adjacent minor bosses of said plurality of minor bosses. 
     
     
         14 . The container of  claim 9  wherein each minor boss of said plurality of minor bosses has a protruding depth ranging from about 2 to about 10 points. 
     
     
         15 . The container of  claim 1  wherein said layered structure further comprises an adhesive connecting said second layer to said first layer. 
     
     
         16 . The container of  claim 15  wherein said adhesive forms a string pattern in said layered structure. 
     
     
         17 . The container of  claim 15  wherein said adhesive is a foam adhesive. 
     
     
         18 . The container of  claim 17  wherein said foam adhesive comprises an organic binder and at least one of an organic filler and an inorganic filler. 
     
     
         19 . A container comprising at least one wall that defines an internal volume and comprises an internal surface and an external surface, said wall being formed as a layered structure comprising:
 a first layer positioned proximate said internal surface;   a second layer positioned proximate said external surface, said second layer comprising a plurality of major bosses protruding into engagement with said first layer to space said second layer from said first layer and a plurality of minor bosses protruding away from said first layer; and   an adhesive positioned between said second layer and said first layer.   
     
     
         20 . A container comprising:
 a side wall that defines a longitudinal axis and an internal volume;   a sleeve coaxially received over said side wall, said sleeve defining a plurality of major bosses and a plurality of minor bosses, said major bosses of said plurality of major bosses having a larger surface area than said minor bosses of said plurality of minor bosses, wherein said major bosses protrude radially inward into engagement with said side wall to space said sleeve from said side wall; and   an adhesive positioned between said sleeve and said side wall.
