Abstract

A corrugated board pallet with considerable strength and simple structure. The corrugated board pallet includes: a structural reinforcing member constructed from corrugated board sheet; structural reinforcing bends formed by bending the structural reinforcing member, axes of the structural reinforcing bends in parallel with the direction that forks of a forklift vehicle are inserted in the pallet; a load carrying member constructed from corrugated cardboard sheet, the load carrying member fixed to an upper surface of the structural reinforcing member, wherein the direction that waves of the corrugated board forming the structural reinforcing member, and the load carrying member are in parallel with the direction that the forks of the forklift vehicle insert into the pallet.

Claims

1. A corrugated board pallet comprising:

a structural reinforcing member constructed from a corrugated board sheet, said structural reinforcing member having an upper surface and a first and a second end;

a plurality of parallel structural reinforcing bends formed in said structural reinforcing member, said plurality of structural reinforcing bends defining channels which extend below said upper surface of said structural reinforcing member said channels extending from said first end to said second end;

a load carrying member made of a corrugated board sheet, said load carrying member connected to said upper surface of said structural reinforcing member and including opposing end portions which are bent to form receiving plates, which entirely cover said first and second of the structural reinforcing bends, and feet which cover at least a portion of a bottom side of the structural reinforcing member and are fixed thereto; and

openings in the receiving plates for receiving forks of a forklift vehicle.

2. A corrugated board pallet as claimed in claim 1, wherein said channels defined by said structural reinforcing bends have a trapezoidal cross-section.

3. A corrugated board pallet as claimed in claim 1, wherein said channels defined by said structural reinforcing bends have a V-shaped cross-section.

4. A corrugated board pallet as claimed in claim 1, wherein said structural reinforcing member comprises corrugated cardboard.

5. A corrugated board pallet as claimed in claim 1, wherein said load carrying member comprises corrugated cardboard.

6. A corrugated board pallet as claimed in claim 1, wherein said structural reinforcing member comprises plastic.

7. A corrugated board pallet as claimed in claim 1, wherein said load carrying member comprises plastic.
