Abstract
Abstract The invention comprises a pallet constructed of a foldable material, such as corrugated paperboard, provided with a series of apertures in the bottom wall adapted to receive support blocks which are integrally attached to a plurality of runners which are disposed in spaced relationship upon the bottom wall. The corrugated paperboard is cut and scored in such a fashion as to permit it to be folded into a tray type pallet which serves to lock the plurality of runners, forming the rigid load-bearing deck of the pallet, into a fixed position.
