Abstract: The present invention provides a container for storing and dispensing food stuffs. The container includes a shell having a sidewall and a bottom wall. Together, the sidewall and the bottom wall define an interior of the container. The bottom wall is detachably connected to the sidewall. The apparatus further includes a liner positioned within the container for holding the food stuffs. Upon the application of an appropriate force, the bottom wall is detached from the sidewall and forced into the interior of the container. As the bottom wall is forced into the interior of the container, the liner collapses and the food stuffs are forced towards an opening in the container opposite to the bottom wall.

The container includes a tubular body of substantially paper material, a cup-shaped end closure of substantially paper material and a cup-shaped membrane having an outer upwardly-extending rim portion of substantially the same height as an upwardly-extending rim portion of the cup-shaped end closure. The membrane and end closure are positioned in an open upper end portion of the body in superimposed relationship with the membrane below the end closure. An upper area of the upper end portion of the body extends above the superimposed rim portions of the membrane and the end closure and is folded inwardly over and around the upper ends of the superimposed rim portions.

Abstract: A dual function overcap for a cylindrical container, having a bead about the top edge and generally used for snack foods, includes a substantially planar covering portion and a downwardly extending lip. The dual function overcap fits over the container with a bead by engaging the downwardly extending lip or can fit a shortened form of the same container without a bead, or the same, or similar, container without a bead. In one form of the invention, the overcap must be flipped over to attach the overcap to the edge of the shortened container. In the preferred form of the invention, a raised channel within the covering portion, receives and retains the edge of the shortened container.

Abstract: A container for being filled with a powdered product includes a container body having an open bottom end and an end closure attached to the container top end portion for closing the container top end portion to adapt the container to be filled through the open bottom end portion with the container in an inverted position. The top end closure includes an easy-opening feature for adapting the container to be easily opened by removing at least a part of the top end closure to obtain access to the powdered product within the container after filling and closure of the bottom end portion.

Abstract: A method is provided of manufacturing an easy-open container. A bodywall layer strip is positioned on a wider liner layer strip to define first and second edge portions on the side of the wider liner layer which extends transversely beyond the bodywall layer side edges. These layers are fed to a mandrel and the first liner layer edge portion is folded-over onto an outside surface of the bodywall layer and a high strength bond is formed therebetween. The resulting layers are spirally wound on the mandrel to form a continuous tube having a spiral seam with the bodywall layer side edges forming a butt joint and with each of the first and second liner layer edge portions extending through the butt joint and out of the spiral seam. The second liner layer edge portion is positioned on the first folded-over liner layer edge portion and a low strength bond is formed therebetween. A flexible label layer is spirally wound onto the tube on the mandrel with its longitudinal edges in overlapped relationship.
