ABSTRACT:
A plastic pallet of twin sheet construction formed in a vacuum thermal forming process. The upper sheet includes a series of downwardly extending hollow upwardly opening bosses arranged in staggered rows and the lower sheet includes a series of upwardly extending hollow downwardly opening bosses generally corresponding in size, number, shape and distribution pattern to the downwardly extending bosses on the upper sheet. The lower walls of the downwardly extending bosses are fused to the upper walls of the upwardly extending bosses in the thermal forming process so as to form a series of vertical columns extending between the upper and lower sheets and maintaining the sheets in fixed spaced relation. The pallet further includes a plurality of legs spaced circumferentially about the periphery of the pallet and depending downardly from the pallet. Each of the legs is formed of a downwardly extending portion of each of the sheets and forms an upwardly opening pocket opening in the upper face of the upper surface of the upper sheet to allow nesting of the pallet with other pallets of similar construction.
