Packaging system to provide fresh packed coffee

Abstract

A packaging system useful for roast and ground coffee, having a container with a bottom, a top, and a body enclosing a perimeter between the bottom and the top. A flexible closure is removably attached and sealed to the protuberance so that the closure seals the interior volume of the container.

1 . A packaging system comprising:
 a container for holding an off-gassing substance and having a longitudinal axis and comprising a bottom, a top, and a body having an enclosed perimeter between the bottom and the top, wherein the bottom, top, and body together define an interior volume; and   the body comprises a multi-layered structure including a collapsible inner layer which holds the off-gassing substance and collapses and expands within the interior volume to compensate for changes in pressure resulting from off-gassing of the substance.   
     
     
         2 . The packaging system of  claim 1 , wherein the collapsible inner layer comprises a bag. 
     
     
         3 . The packaging system of  claim 2 , wherein the top of the bag comprises an upper edge and the container comprises an upper edge, and the upper edge of the bag is sealed to the upper edge of the container. 
     
     
         4 . The packaging system of  claim 3 , wherein a one-way valve is disposed in the bag. 
     
     
         5 . The packaging system of  claim 1 , wherein at least one layer of the body comprises an oxygen barrier. 
     
     
         6 . The packaging system of  claim 1 , wherein the layers of the body other than the collapsible inner layer comprise at least one region of deflection, wherein the region of deflection allows flexion and thereby has less resistance to flexing than an area proximate to the region of deflection. 
     
     
         7 . The packaging system of  claim 1 , wherein at least one of the layers of the body is blow-molded, and comprises a material selected from the group consisting of polycarbonate, linear low density polyethylene, low density polyethylene, high density polyethylene, polyethylene terephthalate, polypropylene, polystyrene, polyvinyl chloride, co-polymers thereof, and combinations thereof. 
     
     
         8 . The packaging system of  claim 1 , further comprising a flexible closure removably attached and sealed to the top of the container, and an overcap. 
     
     
         9 . The packaging system of  claim 8 , wherein the flexible closure has a one-way valve disposed therein. 
     
     
         10 . The packaging system of  claim 8 , wherein the body includes a protuberance proximate to the top, and the closure is removably attached to the protuberance. 
     
     
         11 . The packaging system of  claim 1 , wherein the substance is roast and ground coffee. 
     
     
         12 . The packaging system of  claim 1 , wherein a one-way valve is disposed in the collapsible inner layer. 
     
     
         13 . The packaging system of  claim 1 , wherein the collapsible inner layer comprises an outer surface, and all or part of the outer surface is non-permanently attached to an adjacent layer of the body. 
     
     
         14 . The packaging system of  claim 13 , wherein all or part of the outer surface is laminated to the adjacent layer.
