Abstract

PROBLEM TO BE SOLVED: To reduce the cost by reutilizing a paper tube, which has been discarded after use, for a portion of a pallet. SOLUTION: The pallet comprises a top panel 1 and a bottom panel 2 which are made of a corrugated fiberboard and spacers 3 which are horizontally spaced apart, in the width direction of the pallet, at proper intervals between the top panel 1 and the bottom panel 2, each spacer being oriented in the front and rear directions of the pallet. Each spacer 3 comprises a paper tube 4, as a core material, and a protecting pipe 5 which is prepared by bending a corrugated fiberboard into a rectangular body so as to be wrapped around the tube 4. The bottom surface of the pipe 5 is fixed to the bottom panel 2 through an adhesive, while the top surface of the pipe 5 is fixed to the top panel 1 with an adhesive.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet used for conveying goods.

[0002]

2. Description of the Related Art Conventionally, pallets made of wood have been generally used as such pallets. However, pallets made of this wood are heavy and have problems in terms of handling and high costs. Therefore, cardboard pallets which are easy to handle and inexpensive have been used instead of pallets made of wood. However, there is a demand for further cost reduction in this cardboard pallet.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to solve such a problem and to reduce the cost by reusing a paper tube used and discarded for a part of a pallet. It is.

[0004]

In order to solve this problem, the present invention provides a top plate and a bottom plate made of a corrugated board,
Spacers are provided between the top plate and the bottom plate in the front-rear direction and horizontally provided at appropriate intervals in the width direction of the pallet.Each spacer is formed by a paper tube serving as a core and a paper tube surrounding the paper tube. A protective tube formed by bending a corrugated cardboard plate into a rectangular tube shape so as to cover the space between the bottom surface of the protective tube and the bottom plate, and the top surface of the protective tube and the top plate with an adhesive. The gist of this is. Further, according to the present invention, in any one of the spacers, the protection tube has a substantially trapezoidal front surface, a bottom portion, left and right inclined side portions connected to both sides of the bottom portion, and one of these side portions. An upper surface connected to the upper end of the inner upper surface, and an outer upper surface connected to the upper end of the other side surface so as to overlap the upper surface of the inner upper surface and fixed to the inner upper surface by an adhesive, The gist of the invention is that the outer top surface and the top plate are fixed with an adhesive. Further, according to the present invention, the protection tube of the spacer is configured so that the free end of the outer top surface protrudes from the upper end of one of the side surfaces that connects to one side of the bottom surface, and is located directly above one side of the bottom surface. It is the gist of what has been done.

[0005] With this configuration, it is possible to reuse a paper tube that has been discarded after being used for a part of the pallet, thereby reducing costs.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. First, a first embodiment shown in FIGS. 1 to 4 will be described. 1 is a top plate having a substantially square planar shape. 2 is a bottom plate having a substantially square planar shape. Is constituted by a corrugated board. In order to form a space for inserting a forklift between the top plate 1 and the bottom plate 2, spacers 3 are provided horizontally between the top plate 1 and the bottom plate 2 at appropriate intervals in the width direction of the pallet. Have been. The spacer 3 uses a used paper tube 4 used for winding paper or the like in a roll shape as a core material, and a protective tube 5 formed by bending a corrugated cardboard plate into a rectangular tube around the paper tube 4. The protective tube 5 is covered, and the inner surface of the protective tube 5 and the outer surface of the paper tube 4 are fixed by an adhesive. As the paper tube 4, a pallet having a strength enough to withstand use is used. The protection tube 5 has a substantially trapezoidal front shape, a bottom surface 5a, left and right inclined side surfaces 5b and 5c connected to both sides of the bottom surface 5a, and these side surfaces 5b and 5c.
5c, the inner upper surface 5d connected to the upper end of one side surface 5b, and the upper surface 5d is connected to the upper end of the other side surface 5c so as to overlap the upper surface 5d with an adhesive. And an outer upper surface 5e. The spacer 3 has a length extending in the front-rear direction of the top plate 1 and the bottom plate 2 constituting the upper surface and the lower surface of the pallet. Five spacers are provided at intervals, and the space between the bottom surface 5a and the bottom plate 2 of each spacer 3 and the space between the outer upper surface 5e and the top plate 1 are fixed with an adhesive.

In the above configuration, the load of the load placed on the top plate 1 is received by the five spacers 3. At this time, since the used paper tube 4 used for winding the paper or the like in a roll shape as described above is used as the core material, even if the load applied to the spacer 3 is considerably large, the spacer 3 is not used. Does not deform.
In particular, since the protective tube 5 covering the paper tube 4 of the spacer 3 has a substantially trapezoidal front shape, the protective tube 5 is hardly deformed even when a large load is applied from above.

By the way, of the five spacers 3 provided at appropriate intervals between the top plate 1 and the bottom plate 2, the spacers 3 located at the end portions of the second embodiment shown in FIG. Can also be used. In the protection tube 5 of the spacer 3 according to the second embodiment, the free end portion 5f of the outer upper surface portion 5e is projected from the upper end of one side surface portion 5b connected to one side of the bottom surface portion 5a. It is configured to be located directly above one side. By protruding the free end 5f of the outer upper surface 5e in this manner, it becomes easy to align the free end 5f with the end of the top plate 1. In addition, the shape of the protective tube 5 does not need to have a substantially trapezoidal front shape, and the front shape may be substantially square.

[0009]

As described above, according to the present invention, it is possible to reuse a paper tube which has been discarded after being used for a part of a pallet, thereby reducing costs.
