Abstract: The specification discloses a collapsible pallet box or container composed of a pallet platform and four upright panels connected together at the corner edges by flexible material to form a polygon expandable to a rectangle or collapsible to a flattened parallelogram. The bottom of the polygon panels are removably attached to the pallet. The tops of the panels have a stabilizing grid with interconnected compression elements between the panels to stabilize the panel tops in the expanded rectangular configuration, and interconnectable, releasable hook and loop fasteners on the grid and on the polygon upper end, at the corners of the grid and recessed into the corners of the polygon, to keep the grid secured to the polygon and thereby keep the polygon locked to the pallet.

Abstract: The specification discloses a collapsible pallet box or container composed of a pallet platform and four upright panels connected together at the corner edges by flexible belting at the top and bottom to form a polygon expandable or collapsible to a rectangle or a flattened parallelogram. The bottom of the polygon panels are removably attached to the pallet, preferably by a tongue and groove arrangement of tongues extending from the pallet and grooves in the panels. The tops of the panels have stabilizing, wedging compression elements therebetween at the panel corners to stabilize the panel tops in the expanded rectangular configuration and to keep the panels locked to the pallet.
