Definitions

• the present invention is related to pallets and, more specifically, pallets constructed of corrugated components that include a corrugated sheet and corrugated support blocks stabilised by lists.
• Such pallets are lightweight, recyclable and durable.
• Paper pallets are gaining in popularity as they provide consumers with an easily recyclable option as compared to the standard wood pallets that have been used for years.
• paper pallets while desirably recyclable often bring other undesirable features.
• paper pallets often provide the user with a pallet of reduced strength as compared to a wood pallet of similar size and configuration. The reduced strength limits the load that the pallet may carry and additionally, allows for the damaging of the pallet itself under heavy loads.
• pallets have been made of wood planks nailed together. In one common structure, a series parallel of upper wood planks are nailed to the top of three transversely extending, parallel, and equally-spaced wood support planks.
• Forklift forks can slide under the upper planks in the two parallel channels formed by the three spaced support planks. The forklift can then raise its forks, which lifts the pallet and anything mounted on it.
• wood pallets can withstand the often great abuses to which they are subject.
• the pallet may be dropped or rammed by a forklift or some other machine.
• the pallet may be slid around on a floor or stored outside in the rain or snow. It may be tossed around vigorously when being stored, stacked, or moved.
• a wood pallet can withstand a great deal of this type of use and abuse.
• Wood pallets are, however, expensive, because they eventually breakdown. When they do, little of the wood is useable to make new pallets. To make new pallets, new wood is often required, which requires cutting down of further trees. This is not only expensive but of great environmental concern.
• Wood pallets are also relatively heavy. Their weight increases the cost of storing or shipping products with them. Wood pallets are also dangerous in that, wear and tear causes the wood to splinter and nails to become exposed. The splinters and exposed nails can damage the product being shipped as well as the human operators working with the pallets.
• the paper pallet can be made out of honeycomb paper components.
• the cellular honeycomb core provides remarkable compression strength, lightweight, and significantly improved cushioning ability over the wood pallet. Further, the paper components are totally recyclable as well as biodegradable. The paper pallet can thus be shredded, baled, and sold as recyclable paper, or alternatively returned to the environment through biodegrading.
• One prior art paper pallet is made by International Honeycomb Illinois, Inc. This Honeycomb paper pallet is made of corrugated Kraft Honeycomb runners or blocks glued to the bottom of a corrugated Honeycomb pallet base or to the bottom of a corrugated cardboard carton. This paper pallet can weigh as little as 95% of the traditional wood pallets of a similar configuration. It also eliminates the need for nails and the problems that exposed nails and wood splinters can cause.
• the paper pallet can use three runners in parallel under the deck or carton.
• the three parallel runners form two parallel fork channels separated by the center runner.
• the forks from the forklift then penetrate the two fork channels to lift the pallet or carton.
• three parallel rows of three spaced apart paper honeycomb blocks are glued to the underside of a rectangular Honeycomb paper base.
• the forks can slide under the base from any of the four sides of the pallet.
• the three rows each form two channels for the forks on two opposing sides of the pallet, and the three lines of three spaced apart blocks form two transverse fork channels on the other two opposing sides of the pallet.
• three parallel rows of three equally spaced Honeycomb paper blocks are glued to the underside of a rectangular paper Honeycomb base.
• One parallel paper Honeycomb runner is glued to the bottom of each row of blocks. In this manner, the blocks form channels for forks to penetrate and lift in the fork channels they provide intermediate the pallet base, which is glued to the topside of the blocks, and the runners, which are glued to the bottoms of the blocks.
• EP 1553025 A1 describes a paper pallet comprising a pallet base made from layers of paper sheets and having an upper face, a bottom face and first and second opposite sides, six or nine support members, each of which is mounted on the bottom face of the pallet base and has an upper end, a lower end and side surfaces extending downwardly from the bottom face of the pallet base, six U-shaped lists secured to the support members, each of said lists has an interior wall and an exterior wall, said interior wall contacting the lower end and the side surfaces of at least two of the support members.
• Another object is to provide a pallet that is relatively easy to assemble and manufacture, from readily available components, and recyclable as well.
• a further object is to provide a paper honeycomb or similar pallet that has blocks or runners with relatively great bending resistance and strength.
• a still further object is to provide such a pallet that is relatively resistant to moisture and humidity.
• the present invention provides a corrugated paper pallet comprising:
• a pallet base (1 ) made from one or more layers of corrugated paper sheets, said base having an upper face (1a), a bottom face (1 b), and first and second opposite sides;
• the at least four support members (2) are made from multiple layers of corrugated paper sheets, and wherein the L-shaped lists are rigid to stabilise the pallet; optionally the the L-shaped lists are water resistant.
• the pallet of the present invention comprises six support members (2) and six L- shaped lists (3).
• the L-shaped lists (3) are spaced substantially equidistantly between the opposite sides of the pallet base.
• the support members (2) and pallet base (1 ) comprise paper sheeting or cardboard compressed or glued together.
• the support members have a protective moisture resistant coating, such as polyethylene. This will further prolong the lifetime of pallets of the present invention, particularly when used in humid environments.
• the paper pallet generally comprises support members, a top sheet, and rigid water resistant L-shaped lists to stabilise the construction and protect the corrugated paper from humidity/water coming from the ground/floor on which the pallet is placed.
• the support members are made from laminated corrugated paper sheets.
• the top pad is of a corrugated material and is positioned above the support members.
• the support members are preferably glued onto the top pad.
• the water resistant lists are preferably made from photo paper or a plastic polymer, such as polyethylene, polypropylene, PVC, PTFE, bakelit, epoxy, polystyrene, and polycarbonate.
• a plastic polymer such as polyethylene, polypropylene, PVC, PTFE, bakelit, epoxy, polystyrene, and polycarbonate.
• bioplastics such as starch based plastic, PLA, PHB, PA 1 1 , and biodegradable polyethylene.
• the lists are made from a biodegradable plastic or other biodegradable material, as long as it provides stability to the pallet and is water resistant.
• FIGURE 1 is a bottom view of a pallet according to the present invention.
• FIGURE 2 is a photograph comparing U- and L-shaped lists after impact with a pallet lifter.
• FIG. 1 there is shown a rectangular pallet base (1 ) mounted on support members (2).
• the pallet base (1 ) is a corrugated sheet, while the support members are made from multiple corrugated sheets that are glued together to form the support members.
• the thickness of the base (1 ) varies depending on the load to be carried by the pallet.
• the glue used to secure each block in place is preferably polyvinyl acetate or similar glue.
• the corrugated paper pallet of the present invention which pallet has a pallet base (1 ) made from one or more layers of corrugated paper sheets.
• This base has an upper face (1 a), a bottom face (1 b), and first and second opposite sides.
• Support members (2) are attached to the bottom face (1 b) of the pallet base (1 ), e.g. by glueing.
• In order to provide stability in the pallet L-shaped lists (3) are secured to the support members (2).
• Each of the support members is composed of about ten corrugated boards having the same width and attached to one another by e.g. thermo-melting glue. Shock-absorbing rib members may be disposed within corrugation of the corrugated boards for reinforcing the same.
• the support members are connected under the pallet base by thermo-melting glue.
• each of the edges of the support members and pallet base may be sealed by thermo-melting glue to eliminate any fissure therein.
• An appropriate adhesive that can be used in any glueing according to the present invention is one based on aqueous vinylacetate/ethylene copolymer dispersions.
• FIG. 2 a photograph comparing U- and L-shaped lists after impact with a pallet lifter is shown to demonstrate the stability and robustness of a pallet having L-shaped lists compared with a pallet having a U-shaped list.
• the photograph compare the stability of a set of L-shaped lists attached to supporting members (L-PAL) with a U-shaped list attached to the same kind of support members (U-PAL).
• L-PAL supporting members
• U-PAL the L-shaped lists have been made by dividing a U-shaped list in order to establish a correct comparison.
• U-PAL extend across the U-shaped list, whereas only the L-shaped list that was hit by the pallet lifter is affected, the other L-shaped list of the L-PAL being intact. Moreover, due to the greater flexibility/elasticity of the L-shaped lists the L-shaped list that was hit appears to be less affected in the area of impact than the U-shaped list in corresponding area of impact.
• support members may be attached several layers of carton boards to reinforce the support members.
• the present invention has the following advantages:
• the pallet of the present invention can be recovered for reuse without causing pollution of environment.
• the pallet has much less weight so that the transfer or displacement thereof can be easily performed.
• the present pallet can be automatically mass-produced.
• the present pallet is subject to natural decomposition so that the environment will not be contaminated.
• the present pallet is manufactured at lower cost so that the price thereof is reduced to enhance the competitive ability of the manufacturer.
• the corrugated board may be made of recovered waste paper and can be reused so that the natural resource can be best utilized.
• the support members of the present scaffold board are composed of multiple vertically arranged corrugated boards so that the vertical compression strength thereof is increased to enhance the structural strength and hardness of the pallet.
