Abstract: A large box of sufficient size to carry a coat is cut and folded with the use of a conventionally sized standard die from a single piece of sheet-form material and has side panel structures formed by having an exterior side panel, an integral hinge, and an interior side panel with latching tabs to interlock with the bottom of the box. The exterior and interior side panels have a reduced total height due to the hinged side panels being formed with a bias cut so as to reduce the effective height of the panels to be less than the total height of the completed box while still providing closure integrity and structural stability.

Abstract: A foldable corrugated shipping tray has a one-piece blank which is scored, stripped, and cut for assembly into a rectangular tray with vertical sides and ends, the ends having portions which raise the tray bottom to create an air space below.
