ABSTRACT:
A 180.degree. stackable, nestable plastic tote box has ledge supports and foot supports with a combination of vertical and angled surfaces for guiding an upper box relative to a lower box to a stacked position and resisting the tendency of the upper box to collapse into the lower box when it is heavily loaded. The box also has orientation buttons received in recesses at its rim which give the box an easily visible asymmetric appearance. A drainage collector is molded into each box end wall which underlies a lid of the box and collects drainage from the lid to channel the drainage to the outside of the box, and is formed in walls which help support an upper box on a lower box when it is laterally slid onto it for stacking. The box can be provided with a one-piece lid or a two-piece hinged lid. The one-piece lid has wedge structures depending downwardly from its rim which snap into holes in the top of the box. A padlock hole is formed in an angled wall at the end of the box for locking the lid shut. A piano-type hinge of the two-piece lid has tabs which extend into holes in the box when the lid is shut so as to prevent lateral disengagement of the box side wall from the lid. The box rim also has upstanding wall structures which confront wall structures molded into the lid to resist lateral separation of the hinge joint when the lid is closed.
