Benefits of technology

[0006] It is a first objective of this invention to provide a strong, stiff, price-effective pallet which is durable within the needs of the user.
[0007] It is a second objective of this invention to provide a corrugated pallet which can be shipped to the user in a knocked-down form and easily assembled on site with minimal tools.
[0011] It is a further objective of this invention to provide an easily recyclable product when pallet return is impracticable.

Problems solved by technology

Such construction is suitable for most pallets used for shipping consumer items but is difficult to assemble without expensive automation and also difficult to ship in knock-down form.
Exported pallets pose two problems.

Embodiment Construction

[0018] The pallet of this invention is constructed from standard corrugated paper and may use single or multiple thickness corrugated either coated or uncoated. The rating of the corrugated sheets may be the same or different but would be selected for specific types of use and standardized for that use. Unlike wood, corrugated is readily treated to impart resistance to water, moisture, grease and oil, and made flame retardant. This allows even smaller orders to be prepared for specific shipping conditions without need for ovens or pressure treatment equipment. For international shipment, no fumigation is required and the pallets weight less than equivalent wood pallets.

[0019] The pallet is made from three die cut corrugated sheets. One is a top surface which is a flat sheet having the final length and width dimensions of the pallet. The second is the bottom sheet, identical in length and width to the top sheet but which may be a single layer when the top is two or more layers.

Abstract

A corrugated paper pallet formed from stringers, a top sheet and a bottom sheet. Each stringer is formed from an identical blank which is die cut to form four flaps. Four fold lines are impressed into the corrugated and the blank folded to form a rectangular box section with a double layer on one side. The flaps are folded to close off sections of the box sections and form openings through which lines may be passed. Top and bottom are adhered to parallel stringers. The pallet requires no fumigation, may be coated to resist grease, water or moisture, and the entire pallet is easily recycled

Description

FIELD OF THE INVENTION [0001] This invention relates to high strength recyclable pallets made from corrugated paper. BACKGROUND OF THE INVENTION [0002] Corrugated paper dates to the mid-19th century and corrugated paper for shipping pallets dates to the early 1970's in Japan. Most are based upon multiplying folded corrugated sheets to approximate the wooden stringers of conventional pallets. Wozniacki, U.S. Pat. No. 5,184,558 and Hutchison, U.S. Pat. No. 5,568,774 are representative. Such construction is suitable for most pallets used for shipping consumer items but is difficult to assemble without expensive automation and also difficult to ship in knock-down form. [0003] Corrugated pallets have many advantages. Unlike wooden, plastic, or metal pallets, corrugated can be recycled at the recipient's location as paper / cardboard and does not have to be returned for reuse. Even so called “pallet pools” ship a lot of air. [0004] Exported pallets pose two problems. Return is nearly imposs...
