ABSTRACT:
A plastic pallet having an upper platform and a plurality of plastic legs attached to and extending downward from the underside thereof. The plastic legs comprise upper and lower molded plastic sheets. The upper sheet comprises a generally planar top panel and a skirt extending downwardly from the periphery thereof and having a distal edge defining an annular bonding surface. The top panel further has a hollow conical boss extending downwardly therefrom and including an annular sidewall portion and a bottom wall portion at the lower end thereof. The lower sheet is identical to the upper sheet but is rotated to an inverted position such that a skirt and hollow boss extend upwardly from a lower panel, the distal edge of the skirt defining an annular bonding surface and the hollow boss having an annular side wall portion and a top wall portion at the upper end thereof. When the upper and lower sheets are brought together, the bonding surfaces of the upper and lower sheet skirt edges are placed in registry with one another and fused together, the bottom wall portion of the top panel boss is fused to the upper surface of the bottom panel, the top wall portion of the bottom panel boss is fused to the lower surface of the top panel, and the side wall portions of the top and bottom panel bosses are fused together along an angled interface therebetween.
