ABSTRACT:
An improved tote box especially adapted for use within an automated storage and retrieval system is provided with a bumper rim a short distance from the tote bottom to reduce the moment arm created when the box engages another box or the like. Stacking stops are integrated with the bumper rim to provide additional strength, and the stops circumscribe side drains to allow fluid to be drained without flowing into a lower box in a stack. A divider grid is provided and includes intersecting crosswise and lengthwise divider plates, each Z-shaped and each having mounting slots in one edge and notches in the other. When the plates are mated by seating the slot of a lengthwise plate in the slot of a crosswise plate, the opposing bosses at the mouth of each slot of each plate seat in the notch of an intersecting plate. Tabs on each end of each plate seat in slots in the tote box walls and a ramp overlying the notch restrains the divider plate tab to secure the grid in the tote box.
