Insulating sleeve for containers

Abstract

A container having a sidewall, a folding closure, and a sleeve each formed from a one-piece blank. Also disclosed is a sleeve configuration having a plurality off vents and spacers for locating the vents in a spaced apart orientation relative to a container sidewall.

1 . A container, comprising a sidewall, a folding closure, and a sleeve each formed from a one-piece blank, the folding closure being located adjacent an upper edge of the blank adjacent the sidewall and being configured to provide a substantially open passage in an unfolded orientation and to provide a substantially closed structure in a folded orientation, the sleeve having an edge extending from the blank and configured for wrapping about an exterior portion of the sidewall, the sleeve comprising a sheet material having a plurality of vents extending between opposite interior and exterior surfaces, and a plurality of spacers which extend from the interior surface of the sleeve and include a free portion folded toward the interior surface of the sleeve for spacing the interior surface of the sleeve a desired distance from the exterior sidewall of the container. 
   
   
       2 . The container of  claim 1 , wherein the blank comprises a paperboard blank. 
   
   
       3 . The container of  claim 1 , wherein the blank comprises a plastic blank. 
   
   
       4 . The container of  claim 1 , wherein the container comprises a cup and further includes a bottom opposite the folding closure.

       6 . (canceled) 
   
   
       7 . A one-piece container blank, comprising a foldable sheet material having a foldable closure portion, a sidewall portion, and a sleeve portion positionable adjacent an exterior surface of the sidewall portion when the blank is formed into a container, the sleeve portion extending from the sidewall portion and having a plurality of vents extending between opposite interior and exterior surfaces, and a plurality of spacers which extend from the interior surface of the sleeve and include a free portion which is folded toward the interior surface of the sleeve for spacing the interior surface of the sleeve a desired distance from the exterior sidewall of the container. 
   
   
       8 . (canceled) 
   
   
       9 . (canceled) 
   
   
       10 . A sleeve for positioning adjacent an exterior sidewall of a container, the sleeve comprising a sheet material having a plurality of vents extending between opposite interior and exterior surfaces, and a plurality of spacers extending from the interior surface of the sleeve and configured for spacing the interior surface of the sleeve a desired distance from the exterior sidewall of the container, wherein the sleeve is independent of the sidewall of the container and is installed by slipping around the sidewall. 
   
   
       11 . The sleeve of  claim 10 , wherein the vents comprise open areas defined by portions of the sleeve that are punched out of the sheet material and the spacers comprise the portions of the sleeve that are punched out and which have been folded towards the interior surface of the sleeve. 
   
   
       12 . A container, comprising a sidewall, a folding closure, and a sleeve each formed from a one-piece blank, the folding closure being located adjacent an upper edge of the blank adjacent the sidewall and being configured to provide a substantially open passage in an unfolded orientation and to provide a substantially closed structure in a folded orientation, the substantially closed structure including a pair of gabled lid sections and a pair of lateral lid sections oriented to be linearly aligned with one another and each abutting opposite sides of the gabled lid sections, wherein an edge of the sleeve extends from the blank and the sleeve is configured for wrapping about an exterior portion of the sidewall.
