Abstract
Abstract A pallet is provided having spaced apertured blocks of rigid foam polymeric material bonded or otherwise secured between layers of corrugated paperboard. The pallet may be rendered substantially waterproof. In one embodiment, C-shaped support members may be connected to at least some of the edges of the pallet. Openings may be provided in the C-shaped support members to permit the tines of a fork lift truck to engage the pallet to effect movement thereof. When the C-shaped support members are secured to each of the edges of the pallet, the pallet will be rendered substantially waterproof. In another embodiment, the bottom layer of corrugated paperboard may be eliminated and the top layer utilized to envelop some of the blocks. An intermediate strip of corrugated paperboard may be used to provide a base for the remaining blocks.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
150 words
A pallet comprising a plurality of spaced molded blocks of rigid foam polymeric material having smooth opposed major surfaces, a layer of corrugated paperboard fixedly secured to the top surfaces of said blocks, said layer of corrugated paperboard including sleeves at opposite ends thereof for encircling at least some of said foam polymeric blocks, said sleeve being integral with said layer, said sleeve including sidewalls adjacent the sides of said some of said foam polymeric blocks, said sleeves further including bottom walls for contacting the bottom faces of said some of said foam polymeric blocks, a further strip of corrugated paperboard fixedly secured only to the bottom faces of other of said foam polymeric blocks, said further strip having substantially the same width and length as the bottom wall of said sleeve, and said sidewalls of said sleeve cooperating with said foam polymeric blocks to resist deformation of said pallet.
Claim 2
Dependent Claim
150 words
A pallet comprising a plurality of spaced molded blocks of rigid foam polymeric material having smooth opposed major surfaces, a layer of corrugated paperboard fixedly secured to the top surfaces of said blocks, said layer of corrugated paperboard including sleeves at opposite ends thereof for encircling at least some of said foam polymeric blocks, said sleeve being integral with said layer, said sleeve including sidewalls adjacent the sides of said some of said foam polymeric blocks, said sleeves further including bottom walls for contacting the bottom faces of said some of said foam polymeric blocks, a further strip of corrugated paperboard fixedly secured only to the bottom faces of other of said foam polymeric blocks, said further strip having substantially the same width and length as the bottom wall of said sleeve, and said sidewalls of said sleeve cooperating with said foam polymeric blocks to resist deformation of said pallet.
Claim 3
Dependent Claim
76 words
A pallet as set forth in claim 1 wherein said layer of corrugated paperboard has score lines therein to facilitate forming of said sleeves, said layer of corrugated paperboard being wax coated to render said pallet substantially waterproof, said sleeve including additional sidewalls for contacting other side of some of said foam polymeric blocks, said other sidewalls having flaps connected thereto, and means securing said flaps to the under side of said layer of corrugated paperbOard.
Claim 4
Dependent Claim
71 words
A pallet as set forth in claim 1 wherein the bottom of said pallet is open to permit the tines of a lifting vehicle to travel on the ground and be positioned under said pallet, said pallet being open between said sleeves and said further strip of corrugated paperboard, said pallet between said sleeves and said further strip of corrugated paperboard being substantially composed of a single thickness of corrugated paperboard.
