Description

[Technical field]

[0001] The present invention relates to a paper pallet used for transporting or storing items. [Background technology]

[0002] Traditionally, wooden or plastic pallets have been used to load cargo, but it is known that these pallets are difficult to recycle and dispose of. Therefore, when cargo loaded on pallets is transported, it is often the case that the pallets are returned to the source of transport, as shown in Figure 1, because it costs money to dispose of the unnecessary pallets at the destination.

[0003] Therefore, paper pallets have been developed, which are much easier to dispose of or recycle than wood or plastic, and are inexpensive. Paper pallets can be disposed of more easily than wood or plastic through recycling or incineration, and as shown in Figure 2, there is no need for the delivery destination to return the pallet to the shipping source, which helps reduce transportation costs. In addition, paper pallets can be manufactured inexpensively by using recycled paper.

[0004] For example, Patent Document 1 discloses a cardboard pallet comprising a top plate and a bottom plate arranged opposite each other with a gap between them in the vertical direction, and a number of supports connected to the opposing surfaces of the top plate and the bottom plate, wherein the top plate and the bottom plate are each a laminate formed by stacking a number of cardboard sheets so that the ridges of the cores intersect, and the supports are a rolled body formed by rolling a strip-shaped cardboard sheet into a cylindrical shape so that the ridges of the cores extend in the vertical direction.

[0005] This technology not only makes it possible to solve the above-mentioned waste disposal problems and manufacturing cost problems, but also makes it possible to minimize the risk of the top and bottom plates bending downward when a load is applied from above, as is the case with typical paper pallets.

[0006] Also, for example, Patent Document 2 discloses a paper pallet having a paper top plate on which cargo is loaded, and a top plate reinforcing material that is provided on the top plate and arranged on the underside thereof to reinforce the top plate, the top plate reinforcing material having a housing made of the same paper material as the material forming the top plate, and a paper tube that is stored in and removable from the housing, and the housing is fixed to the top plate. According to this technology, it is said that the strength of the paper pallet can be ensured by the cardboard tube. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Utility Model Registration No. 3234104 [Patent Document 2] JP 2005-289413 A Summary of the Invention [Problem to be solved by the invention]

[0008] However, it has been pointed out in the field that the technology disclosed in the above Patent Document 1 and the like is still weak in terms of strength when the weight of the cargo or the like to be loaded is heavy.

[0009] The present invention is intended to solve the above-mentioned problems, and aims to provide a paper pallet that increases the strength of the components of the pallet and, by combining them, improves the strength of the pallet as a whole, while also solving problems such as disposal. [Means for solving the problem]

[0010] In order to address the above-mentioned problems, the present invention provides the following technical solutions. That is, the invention described in claim 1 is a paper pallet comprising a top plate on which cargo is loaded, a bottom plate arranged opposite the top plate with a gap in the vertical direction, and a cylindrical paper tube connected between the opposing surfaces of the top plate and the bottom plate and supporting the top plate in the axial direction from below, wherein the top plate is made of a paper honeycomb board and the bottom plate is made of a paper board.

[0011] The invention described in claim 2 is a paper pallet described in claim 1, characterized in that the cylindrical paper tube is connected between opposing surfaces at each corner of the top plate and the bottom plate, between opposing surfaces near the center of each side of the top plate and the bottom plate, and between opposing surfaces near the center of the top plate and the bottom plate. Effect of the Invention

[0012] According to the present invention, since the material is paper, disposal is easy, and as a result, direct transportation in pallet units can be realized, thereby reducing costs such as warehousing and retrieval, storage, transshipment, center fees, and pallet management.

[0013] In addition, according to the present invention, it is possible to reduce product inventory and waste, and since the workload of transportation and other tasks is reduced, it is possible to reduce the frequency of deliveries (this is in line with the logistics standardization led by the Japanese government). Furthermore, according to the present invention, since the pallets are made of paper, they can be recycled as resource waste, and this also addresses the issue of environmental consideration (SDGs).

[0014] Furthermore, according to the present invention, even though the pallet is made of paper, the strength of the components of the pallet is high, and the combination of each component gives the pallet a high strength as a whole, so that it can adequately handle even heavy cargoes. [Brief description of the drawings]

[0015] [Figure 1] FIG. 1 is a schematic diagram showing a conventional logistics flow. [Diagram 2] FIG. 1 is a schematic diagram showing a conventional logistics flow using a paper pallet. [Diagram 3] FIG. 1 shows an embodiment of a paper pallet according to the present invention, where (a) is a front view, (b) is a right side view, (c) is a bottom view, (d) is a plan view, (e) is a cross-sectional view along line A-A', and (f) is a bottom oblique view. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] An embodiment of a paper pallet according to the present invention will be described with reference to the drawings. Fig. 3 shows an embodiment of a paper pallet according to the present invention, where (a) is a front view, (b) is a right side view, (c) is a bottom view, (d) is a plan view, (e) is a cross-sectional view along line A-A', and (f) is a bottom perspective view. Note that, with regard to the reference numerals, 10 denotes a paper pallet, 12 denotes a top plate, 14 denotes a bottom plate, 16 denotes a cylindrical cardboard tube (each corner), 18 denotes a cylindrical cardboard tube (center of each side), 20 denotes a cylindrical cardboard tube (center), and 22 denotes a cutout portion.

[0017] First, as shown in Fig. 3, the paper pallet 10 in this embodiment has a top plate 12 on which cargo is loaded, a bottom plate 14 arranged opposite the top plate 12 with a gap in the vertical direction, and a cylindrical paper tube 16 (18) connected between the opposing surfaces of the top plate 12 and the bottom plate 14 and supporting the top plate 12 in the axial direction from below, the top plate 12 being made of a paper honeycomb board, and the bottom plate 14 being made of a paper board. As such, because a high-strength honeycomb board is used for the top plate 12, even though it is a paper pallet, it is strong and can be fully used even when the weight of the cargo to be loaded is heavy.

[0018] Furthermore, in this embodiment, the cylindrical paper tube 16 is connected between the opposing surfaces at each corner of the top plate 12 and the bottom plate 14, the cylindrical paper tube 18 is connected between the opposing surfaces near the center of each side of the top plate 12 and the bottom plate 14, and the cylindrical paper tube 20 is connected between the opposing surfaces near the center of the top plate 12 and the bottom plate 14. It is preferable to use thick paper tubes that can withstand lateral thrusts for the cylindrical paper tubes 16, 18, and 20. In addition, since a paper honeycomb board, a paper board, and a cylindrical paper tube are used in this embodiment, the weight of the entire pallet can be reduced, and furthermore, it can be recycled as resource waste.

[0019] Furthermore, because it is a paper pallet, there is no need to carry out fumigation (heat treatment) even when exporting overseas, which allows for a significant reduction in transportation costs. Note that, in the bottom plate 14 of the paper pallet 10 in this embodiment, as shown in Figures 3(c), (e) and (f), cutouts 22 are provided symmetrically in the top, bottom, left and right directions, and these cutouts 22 are intended to allow the tires of the hand lift to directly touch the ground when the hand lift is in use, and do not limit the present invention. [Industrial Applicability]

[0020] The paper pallet according to the present invention is made of paper, so that disposal is easy. As a result, direct transportation of pallets can be realized, and costs such as warehouse entry and exit, storage, transshipment, center fees, and pallet management can be reduced. In addition, it is possible to reduce product inventory and waste loss, and the workload of transportation and other tasks is reduced, making it possible to reduce the frequency of delivery (in line with the logistics standardization led by the Japanese government). Furthermore, according to the present invention, since the pallet is made of paper, it can be recycled as resource waste, and the problem of environmental consideration (SDGs) can be addressed. Furthermore, even if it is made of paper, the strength of the components of the pallet is high, and the strength of the pallet as a whole is also high depending on the combination of the components, so it can be fully handled even when the weight of the cargo to be loaded is heavy.
