ABSTRACT:
A thermoformed twin sheet pallet comprising an upper plastic sheet and a lower plastic sheet, the sheets being fused together to form a platform structure and a plurality of leg structures downstanding from the platform structure in spaced relation and defining a plurality of forklift passages therebetween. The leg structures are formed of spaced downstanding leg portions of the upper sheet fused in vertically overlapping relation to spaced upstanding leg portions of the lower sheet, and main body planar portions of the upper sheet between the spaced downstanding leg portions coact with main body planar portions of the lower sheet between the spaced upstanding leg portions to define the forklift passages. The lower sheet further includes an upstanding flange portion extending around the perimeter of the lower sheet and fused to the perimeter of the upper sheet and openings are provided in the flange portion, in alignment with the forklift passages, to provide forklift access to the forklift passages. A flap is provided in each opening which is yieldable to allow entry of a forklift into the opening for access to the respective forklift passage. The downstanding leg portions of the upper sheet comprise clusters of hollow protrusions opening in the upper face of the upper sheet and the upstanding leg portions of the lower sheet comprise clusters of hollow protrusions opening in the lower face of the lower sheet and including sidewalls fused to sidewalls of the downstanding protrusions of the upper sheet.
