Abstract
A passive locking system is used to attach molded plastic bottom and cover members to the bottom and top edges of a four-sided sleeve to create a container that can be handled by a forklift and knocked down for storage and/or return shipment. The locks comprise molded tabs and receiver slots and allow for easy attachment and removal of the sleeve to the bottom and top members without the need for tools or manipulation of slide latches. In the preferred embodiment, foldable clips are attached to the sleeve edges to provide tabs on the sleeve. The clip tabs enter into apertures in the outside rim of the pallet and cover only when the sleeve edges are fully inserted into the pallet and cover.
