Description

Corrugated Pallet {CORRUGATED CARDBOARD PALETTE}

The present invention relates to a pallet, and more particularly to a corrugated pallet that is resistant to moisture and moisture, and that can withstand large loads (vertical loads).

In general, pallets have been widely used as a pedestal of cargo to allow cargo to be safely stacked, so that cargo can be loaded and unloaded from the loading box of the transportation vehicle more quickly.

Conventional pallets are typically formed in the form of a rectangular plate, the wood pallet is used in most cases.

Conventional wood pallets are made by nailing several boards and pieces of wood, and if knots occur, they are not only structurally vulnerable due to clicks or damage factors, but also have a high moisture content so that bacteria (fungus) can easily grow. There is a disadvantage to provide. In particular, the wooden pallet is a heavy weight to reduce the loading efficiency of the cargo to act as a major cause to significantly increase the logistics cost, and when the end of life is difficult to recycle because it is difficult to dispose disposal.

Therefore, in recent years to solve some of the shortcomings of wooden pallets, paper-made pallets are widely used in industrial sites.

As shown in FIG. 5, the conventional paper pallet 10 forms the top plate 12 by corrugated paper, and the top plate 12 has branch tubes 14 for supporting the struts at equal intervals. This conventional paper pallet 10 has the advantage of light weight, while the following has a problem.

First, the portion of the upper plate 12 which is in contact with the branch pipe 14 when pressed under a large loading load is pressed against the load, and has the disadvantage of being crushed. Second, since the contact area between the branch pipe and the top plate was small, there was no other method than the method of fixing using a stapler. This fixing method has a disadvantage in that workability is very poor. Further, even if the branch pipe is fixed to the top plate by this process method, there is a disadvantage that the branch pipe is easily detached from the top plate when a strong impact is applied from the side. Third, since the base tubes must be attached to the top plate in an adhesive manner in a row and row, assembly is very poor.

As such, the conventional paper pallet 10 is used in extremely limited circumstances due to these disadvantages.

The present invention is to solve such a conventional problem, the object of the present invention is to provide a new type of corrugated pallet that is excellent in assembly (workability) and durability, and able to withstand heavy heavy loads.

1 is an exploded perspective view of a cardboard pallet according to an embodiment of the present invention.

As shown in Figure 1, the corrugated cardboard pallet 100 according to a preferred embodiment of the present invention consists of the upper plate 110, the support box 120, the branch pipes 140 and the lower plate 150.

The upper plate 110 is formed of a hard board resistant to moisture, and the lower plate 150 is formed by overlapping a plurality of corrugated cardboards. Here, the lower plate 150 is laminated to combine the cardboard so that the bone of the cardboard perpendicular to each other. Three support boxes 120 are installed between the upper plate 110 and the lower plate 150 by an adhesive.

The support box 120 is a hollow cardboard box type, and provides improved assembly compared to the prior art. FIG. 2 is an exploded view of the support box, and FIG. 3 is a plan view illustrating a state in which the first side part is assembled and fixed in the support box.

2 and 3, the support box 120 has a rectangular bottom portion 122 formed at the center thereof, and a length L of the bottom portion 122 at the front and rear ends of the bottom portion 122. The front portion 123 and the rear portion 124 are formed to be folded by the bending line 50 to the same length as the (). The rear wing 124a is formed at both sides of the rear portion 124 at the same height as the height H of the rear portion 124, and the rear portion 124 is also formed at both sides of the front portion 123. The front wing 123a is extended to the same height as the height (H).

Side portions 125 are formed at both side ends of the bottom portion 122 to have the same width as the width W of the bottom portion 122. In this case, the height Ha of the side portion 125 is the rear portion ( It is equal to the height H of 124. On the other hand, the side portion 125 is also formed with the side wing blades 125a extending in the same width as the width W of the bottom portion 122. For example, it is preferable that the height Hb of the side blade 125a is formed at least shorter than the height Ha of the side blade 125. The rear cover portion 124 has a rectangular cover portion 229 is formed to extend, the cover portion wings 229a are formed on both sides of the cover portion 229, respectively.

On the other hand, the support box 120 has a fitting assembly means for improving the assembly.
