Abstract
A pallet (10) is disclosed which is particularly adapted for being constructed of moldable thermoplastic materials. The pallet includes a load-bearing surface (12) supported by a plurality of feet (32) with the load-bearing surface (12) being constructed of a pair of sheets of the thermoplastic material (13, 15) located in spaced parallel relationship to each other. Respective top (22, 24) and bottom (26) channels are formed in the upper and lower sheets of material (13, 15) with the bottoms of each of the channels (22, 24, 26) being joined to the bottom of the channels from the other sheet of material to securely and rigidly fix the two sheets of material (13, 15) together. The feet (32) include alternating solid (40) and hollow (38) portions which serve to make the feet (32) extremely strong. An alternative embodiment of the present invention includes a self-draining feature so that the channels (122) on the top surface of the pallet drain into the feet (132) with the fluid entering the feet (132), draining from a hole (143) provided in the bottoms thereof.
