Abstract
The invention provides cleats or bars for interlocking produce lug boxes at the top tier of multiple tier columns of such boxes arranged on a pallet in a unitized stack. The lug boxes have rectangular plastic frames at their ends, surmounted by spacers, and the invention provides cleats or bars which clamp to these spacers at the top of the stack. The end frames of the containers engage end-frame to end-frame in the stack, and are provided with interlocking elements which prevent lateral shifting of individual containers. In combination with the use of these interlocking elements, the clamping bars at the top provide an especially well integrated stack of containers. In addition, certain binding tapes are used, and these interengage with guides and recesses in the end frames and locking bars to unitize and stabilize the stack. The clamping bars also provide flat platforms on which can be mounted a second pallet supporting a second stack of containers.
