Abstract: This invention relates to a collapsible box for shipments between plants of heavy loads up to 5,000+ pounds per box for heavy parts. The box is designed to be collapsible to be returned flat for less shipping costs. The box is fabricated in an octagonal shape made from 8 sides of hardboard on the outside, and a sheet of aluminum secured thereto with hinges holding the sides together in an octagon with strips holding the box on a pallet.The hinges hold the sides together from the base on the pallet to the top of the box. The hinges are of two types. One hinge is a double pivot for opposite corners of the collapsed box, and it folds back on itself with two pivot points, shown in FIGS. 6 and 7. The other hinge folds from a flat position on the top or bottom of the collapsed position to a 45.degree. bend inwardly toward the assembled box with only one pivot point, shown in FIG. 4 and 5.
