Abstract
Abstract A plastic pallet has a flat upper surface and a plurality of supporting legs. The pallet is formed of injection molded plastic or injection molded plastic foam and the legs comprise a unique structure for providing rigidity and support, along with a peripheral moat structure which includes a peripheral, downwardly-extending wall projecting from the upper surface. The recesses provide good support for the pallet while eliminating the necessity for a relief of material, to a great extent, adjacent the periphery of the pallet.
