Abstract: A container is made in a collapsed configuration with bellows fold corners for self-erection and has spaced-panel end walls encompassing hollow columns for vertical reinforcement. An outer end wall panel is joined to the container bottom, leading to a ledge panel that is horizontal when the container is erected, and an inner end wall panel folds over and down to lock via tabs into openings in the bottom. The hollow columns reside under the ledge panel and are provided by column-forming panels folded inwardly and glued to the inner end wall panels. Score or fold lines define the corners of the hollow column and are placed to bear against inner sides of the front and back walls, which holds the hollow columns open when the container is erected. The column-forming panels have protruding tabs backed by corresponding tabs on a ledge panel between inner and outer panels of the end walls. These tabs form a two thickness registration tab that engages a corresponding opening in the container bottom for stacking.
Abstract: A collapsible container for packing, shipping and displaying articles is formed from an integral piece of corrugated craft, paperboard or similar foldable material. The container includes a plurality of panels which are connected to form a bottom, front, back and exterior sidewalls, and preferably also a top. A bellows fold connects each of the exterior sidewalls with at least one of the front and back walls. Each exterior sidewall is provided with a respective interior sidewall which together support a horizontal ledge. The horizontal ledges are useful for stacking multiple cartons in vertical alignment and can support containers that are somewhat out of registry. Locking tabs extend from the bellows panels of the container to limit lateral deflection of the sides and deformation of the container.
Abstract: A shipping and display container is formed from an integral piece of corrugated board, paperboard, or the like. The container has a top which includes two opposing flaps allowing access to the contained space of the container for loading. The two flaps are adhered to each other at their opposing edges when the container is closed and sealed for shipping. The top may be removed from the container by separating the top from the sidewalls at perforation lines extending generally at the outer edges of the top. The front of the container has removable portions which are integrally attached to the top so that a pair of windows is formed when the container is opened by the end user's removal of the top together with the removable portions. Product is accessible through the two windows as well as through the top of the opened container. The container is folded and glued from an integral flat blank, and is erected from a collapsed parallelogram shape by moving together outer transverse edges.
