Abstract: A container assembly comprises a master container and a plurality of sub-containers to be carried therein. The master container and the sub-containers are of the knock-down reusable type. Each container includes foldable sides which are maintained in an erected posture by resilient band. Each container provides a pair of corner folds at each corner which are effective to withstand vertical and torsional loads. The master container and sub-containers thus collectively provide four corner folds at each corner, and four corner folds at points along the side walls where two corners of two sub-containers meet. If four or more sub-containers are employed, eight corner folds are provided internally of the master container where four corners of the sub-containers meet. The container assembly is thus able to withstand substantial vertical and torsional loads during shipping. By removing the band from the master container, the sides thereof can be collapsed, exposing the sub-containers.

Abstract: A collapsible and reusable container is formed from a foldable base member, a collar and divider members made of a fibrous paperboard sheet material especially adapted for citrus fruit. The central base portion has an area encompassed by fold lines which define a hexagon. Each of the divider members constitutes a complete triangle to subdivide the base area into triangular compartments. The corners of the divider members reinforce the corners of the base member side walls. The collar encircles the outer surface of the side walls of the base member, also reinforces the side wall members and corners, and urges the divider members tightly together thereby forming a rigid container structure. Hand engaging openings in the side walls and openings in the central base portion and dividers provide ventilation. The entire container can be disassembled and the parts all folded flat for return and storage awaiting reuse.
