ABSTRACT:
A reinforced twin-sheet thermoformed pallet is disclosed which has a substantially planar load-bearing member which is formed from an upper sheet of thermoplastic material and a lower sheet of thermoplastic material located generally in fixed parallel relationship to each other. A plurality of concave depressions in the load-bearing member form feet which depend from the load-bearing member. Each foot is formed as a downwardly depending portion of each of the two sheets of material joined together. Each foot has an inner foot floor formed from the upper sheet and an outer foot floor formed from the lower sheet. A quantity of reinforcing thermoplastic material is located between the inner and outer walls of each foot and is fused to the upper and lower sheets to form an integral foot floor which is substantially parallel to the load-bearing member. The thickness of the foot floor is substantially greater than the combined thicknesses of the upper and lower sheets. Preferably the upper and lower sheets and the reinforcing thermoplastic material are all composed of the same thermoplastic material. The pallet has reinforced feet of substantially increased thickness which extend the usable life of the pallet. This pallet, being composed of a single plastic material, may be economically crushed and recycled.
