  • Corrugated pallet
    Patent number: 9630742
    Abstract: A corrugated paperboard pallet is produced from two flat blanks which comprise a pallet top and a pallet bottom. The two blanks are each folded to produce only two parallel vertically extending double thickness ribs, three horizontal panels, two vertical side walls and two horizontal flaps. The ribs of the pallet top and pallet bottom lock each other from opening in the center of the pallet by intersecting perpendicularly with notches in the ribs. The horizontal flaps lock the ribs from opening at the edges of the pallet by intersecting perpendicularly with notches, and the vertical sidewalls include vertical flaps that open inward defining fork passages whereby the vertical flaps lock said horizontal flaps from opening.
