Abstract
Abstract This invention is concerned with a four-sided pallet container which is used in connection with a bottom section. The pallet container of this invention is particularly suited for use in connection with produce and as a bulk industrial container. The pallet container utilizes a pair of opposing primary panels and a pair of opposing secondary panels. The primary and secondary panels are locked into position by opposing tapers. When positioned in a rectangular or square locking relationship, the primary and secondary panels are rigidly secured in a rectangular or square relationship when pressure is supplied to the underside of said primary panels. The pallet container of this invention can utilize a plurality of bottom sections. After assembly the pallet container of this invention can be readily broken down or disassembled. In disassembly, as a result of the integral, opposing locking taper means the secondary panel can be removed from the primary panel when the secondary panel is lifted approximately one half of the height of the primary panel. The component parts of the pallet container of this invention may be readily formed from polymeric materials.
