Abstract
A reusable envelope tray system includes a stacking tray with linear structural corrugations and a support unit. The tray bottom has parallel side fold lines extending along the corrugations and parallel end fold lines transverse to the corrugations. A sidewall extends upwardly from each bottom side fold line, and an end wall extends upwardly from each bottom end fold line. Each end wall has an outer portion connected to the bottom wall and an inner portion connected to the outer portion. Fold lines connect the inner and outer portions to provide a bearing surface during stacking. The outer portion includes a hand hole and the inner portion includes a return hinge extending transverse to the corrugations and reachable through the hand hole. The hinge allows bending of the inner portion under folding assembly/disassembly of the tray. The support unit has upstanding posts received in apertures on the tray bottom.
