Abstract
A package including an outer container, with upper narrow flanges, and which can be folded into the container form, and includes interiorly thereof at least one liner, the liner being shaped so as to provide for its interfitting within the container, having clearance on at least two opposite sides from the container walls, while the other two walls of the liner are contiguous with, or adhesively connected to, the interior of the other two walls of the container. The liner has beveled panels, at its corners, so that when the container of the package is folded into a flattened configuration, the liner follows suit, and can likewise be folded simultaneously flat with the container, so that the package blank can then be shipped or stored in that condition. When the package is erected, for filling, the liner shapes into the open configuration, with the container, can be filled with bulk material, and then a particular style of cap formed of a cover panel, with beveled flanges along each edge embrace the narrow upper flanges of the container, to secure the package into closure, at which time it may be banded or otherwise secured into closure.
