Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in reality, since the sizes of the pallet and the box body were each determined independently, the box bodies could not be densely loaded on the pallet, a large gap was generated between the box bodies on the pallet, and the transport efficiency was reduced.

[0005] Incidentally, Patent Document 1, such as FIG. 3, shows a form in which boxes are loaded on a pallet, and it appears as if the boxes are densely loaded on the pallet. However, as shown by precedents such as Hei 8 (Gyoke) No. 42 and Hei 18 (Gyoke) No. 10342, in the first place, patent drawings are drawn for the convenience of explaining the technical content of the invention and are not drawn with the accuracy required for design drawings. Therefore, the size of the pallet or the size of the boxes cannot be specified from the drawings of Patent Document 1, nor can the relationship between the two be grasped. And in reality, as described above, a large gap was generated between the boxes on the pallet, and the transport efficiency was reduced.

[0006] An object of the present invention is to provide a carrier capable of realizing high transport efficiency of boxes.

Means for Solving the Problems

[0007] A first aspect of the present invention is a pallet having a rectangular loading surface, and a plurality of boxes loaded on the loading surface comprising a carrier, wherein the bottom surface of the box faces the loading surface, and the following formula (1): y - nx < z (1) (In the formula, n is an integer of 2 or more, x is the length of the side constituting the bottom surface, y is the length of the side constituting the loading surface, and z is a length less than x) is satisfied.

[0008] It is preferable that the loading surface is square.

[0009] It is preferable that the bottom surface is square.

[0010] The n may be 3.

[0011] It is preferable that the z is 2 cm.

[0012] The second aspect of the present invention is a pallet having a rectangular loading surface, and a plurality of boxes loaded on the loading surface to form a loaded body, wherein the bottom surface of the box faces the loading surface, and the following formula (2) mS b <S p <(m + i)S b (2) (wherein m is an integer of 2 or more, S b = the area of the bottom surface, S p = the area of the loading surface, and i is a positive number of 1 or less) is satisfied.

[0013] The m may be 9.

[0014] The i is preferably 0.2 or less.

[0015] And the following matters apply to each of the first aspect and the second aspect of the present invention.

[0016] The box is preferably made of cardboard.

[0017] The box preferably contains an article.

[0018] The article is preferably toilet paper.

[0019] The pallet preferably has an insertion port into which the fork of a forklift can be inserted.

[0020] In the loaded body of the present invention, it is preferable that the plurality of boxes are loaded in multiple stages.

[0021] The loaded body of the present invention may be wrapped with a film or a sheet.

[0022] In the carrier of the present invention, the plurality of boxes may be fixed to each other by an adhesive.

Advantages of the Invention

[0023] In the carrier of the present invention, boxes can be densely loaded on a pallet. Therefore, according to the present invention, high transportation efficiency of the boxes can be realized.

[0024] The present invention is suitable for transporting paper products such as toilet paper, which have a relatively small weight per unit and particularly require efficient transportation.

[0025] In recent years, due to problems such as a shortage of truck drivers, high transportation efficiency has been required when transporting boxes. However, according to the present invention, the transportation efficiency can be increased and the transportation cost per box can be reduced.

[0026] Also, by densely loading the boxes on the pallet, the gap between the boxes is reduced, and it is possible to prevent the boxes from collapsing during transportation.

Modes for Carrying Out the Invention

[0028] As a result of intensive studies, the inventors have found that by controlling the relationship between the size of the pallet and the size of the box, it is possible to densely load the boxes on the pallet and increase the transportation efficiency.

[0029] In the first aspect of the present invention, by controlling the relationship between the length of the side forming the rectangular loading surface of the pallet and the length of the side forming the bottom surface of the box body facing the loading surface within a predetermined range, the gap between the box bodies on the loading surface is made small, and the box bodies can be densely loaded on the pallet. Here, "facing" means the bottom surface of the box body that can directly face the loading surface, and the bottom surface of the box body "facing" the loading surface of the pallet can be in contact with the loading surface.

[0030] Heretofore, in order to improve the transportation efficiency of the box body, controlling the relationship between the length of the side forming the rectangular loading surface of the pallet and the length of the side forming the bottom surface of the box body facing the loading surface within a predetermined range has not been done. The first aspect of the present invention is the first to focus on the relationship between the length of the side forming the rectangular loading surface of the pallet and the length of the side forming the bottom surface of the box body facing the loading surface.

[0031] Specifically, in the first aspect of the present invention, the rectangular loading surface of the pallet and the bottom surface of the box body satisfy the following formula (1): y - nx < z (1) (wherein, n is an integer of 2 or more, x is the length of the side forming the bottom surface, y is the length of the side forming the loading surface, and z is a length less than x), the box body is loaded on the loading surface of the pallet.

[0032] The value of n is not particularly limited as long as it is a positive number of 2 or more. For example, it can be 2 to 8, preferably 3 to 6, and more preferably 3.

[0033] In the above formula (1), nx means the total length of one side (bottom side) constituting the bottom surface of each box body when a plurality of box bodies are stacked on the loading surface of the pallet adjacent to each other. The sides (bottom sides) constituting the bottom surface of the box body intersect at a substantially right angle. Here, "substantially right angle" means that it is a right angle in design, but actually includes cases where it is slightly deviated from a right angle in the mathematical sense due to the material constituting the box body, the contents of the box body, the usage situation, etc.

[0034] When stacking box bodies on top of each other on the loading surface of the pallet, nx means the total length of one side (bottom side) constituting the bottom surface of each of the plurality of box bodies existing at the bottom.

[0035] On the other hand, y is the length of one side of the loading surface of the pallet. The sides constituting the loading surface of the pallet intersect at a substantially right angle. Here, "substantially right angle" means that it is a right angle in design, but actually includes cases where it is slightly deviated from a right angle in the mathematical sense due to the material constituting the pallet, the usage situation, etc.

[0036] Therefore, y - nx means the maximum value of the length of the gap between the box bodies when a plurality of box bodies are stacked adjacent to each other (with the sides constituting the bottom surface of the box body and the sides constituting the loading surface overlapping) on the loading surface of the pallet. And the above formula (1) means that the maximum value of the gap is less than the length of one side constituting the bottom surface of one box (z). In this way, since the gap between the box bodies on the loading surface of the pallet is suppressed to be at most less than the length of the bottom side of one box, the box bodies can be densely stacked on the loading surface.

[0037] The value of z is a positive number of 0 or more, and is not particularly limited as long as it is less than x. For example, it can be 20 cm, 10 cm, 5 cm, or 2 cm.

[0038] Also, in the first aspect of the present invention, when a plurality of box bodies are stacked adjacent to each other (with the sides constituting the bottom surface of the box body and the sides constituting the loading surface overlapping) on the loading surface of the pallet, since the maximum value of the length of the gap between the box bodies on the loading surface of the pallet is less than the length of one side constituting the bottom surface of one box, the collapse of the box bodies is less likely to occur.

[0039] On the other hand, in the second aspect of the present invention, by controlling the relationship between the area of the loading surface of the pallet and the area of the bottom surface of the box body within a predetermined range, the gap between the box bodies on the loading surface is made small, and the box bodies can be densely loaded on the pallet.

[0040] Heretofore, in order to improve the transportation efficiency of the box body, controlling the relationship between the area of the rectangular loading surface of the pallet and the area of the bottom surface of the box body facing the loading surface within a predetermined range has not been performed. The second aspect of the present invention is the first to focus on the relationship between the area of the rectangular loading surface of the pallet and the area of the bottom surface of the box body facing the loading surface.

[0041] Specifically, in the second aspect of the present invention, the rectangular loading surface of the pallet and the bottom surface of the box body satisfy the following formula (2): mS b <S p <(m + i)S b (2) (In the formula, m is an integer of 2 or more, S b = the area of the bottom surface, S p = the area of the loading surface, and i is a positive number of 1 or less), the box body is loaded on the loading surface of the pallet.

[0042] The value of m is not particularly limited as long as it is an integer of 2 or more. For example, it can be 4 or more, preferably 9 or more, and more preferably 9.

[0043] In the above formula (2), mS b means the sum of the areas of the bottom surfaces of the box bodies when a plurality of box bodies are loaded. The shape of the bottom surface of each box body is substantially rectangular. Here, "substantially rectangular" means that it is rectangular (square or rectangle) in design, but actually includes cases where it slightly deviates from a rectangle in a mathematical sense due to the material constituting the box body, the contents of the box body, etc.

[0044] In addition, when stacking boxes on the loading surface of the pallet, mS b means the total area of the bottom surfaces of a plurality of boxes that are located at the bottom most.

[0045] On the other hand, S p is the area of the loading surface of the pallet. Therefore, the above formula (2) means that when stacking a plurality of boxes on the loading surface, the total area of the gaps between the boxes on the loading surface is less than the bottom area of one box. In this way, since the area of the gaps between the boxes on the loading surface of the pallet is suppressed to be at most less than the bottom area of one box, the boxes can be densely stacked on the loading surface.

[0046] The value of i is not particularly limited as long as it is a positive number of 1 or less. For example, it can be 0.8, 0.6, 0.4, or 0.2.

[0047] The smaller the numerical value of i, the closer the area of the loading surface of the pallet is to an integer multiple of the bottom area of the box, and the more boxes will be stacked on the loading surface of the pallet, which is preferable.

[0048] Also, in the second aspect of the present invention, since the area of the gaps between the boxes on the loading surface of the pallet is less than the bottom area of one box, the boxes are less likely to collapse.

[0049] The first aspect and the second aspect of the present invention can be embodiments including only each aspect, or can also be embodiments including both aspects. That is, the loading carrier of the present invention may satisfy either one of the above formulas (1) and (2), or may satisfy both of the above formulas (1) and (2).

[0050] Hereinafter, as an embodiment including both the first aspect and the second aspect of the present invention, an example of an embodiment of the present invention will be described with reference to the drawings. In the description of the embodiment, the same reference numerals are assigned to the same components, and duplicate descriptions are omitted. In the following description, the up-down, left-right directions are set for convenience in explaining the embodiment, and do not limit the configuration or usage state of the carrier.

[0051] FIG. 1 shows an example of a pallet used in an embodiment of the carrier of the present invention. The pallet 1 shown in FIG. 1 is made of a resin such as polyethylene and includes a rectangular loading surface 11 for loading boxes. The loading surface 11 does not have to be a mathematically exact rectangle, and for the safety of the user, the corners of the loading surface 11 may be rounded.

[0052] As long as the shape of the loading surface 11 is rectangular, it is not particularly limited, and it can be rectangular or square, but a square is preferred. It is more preferable that the loading surface 11 is a square with rounded corners.

[0053] As the pallet 1, for example, one having a square loading surface 11 with a side length of 1100 mm and a height of 150 mm can be used.

[0054] The form of the surface of the loading surface 11 is not particularly limited as long as the box described later can be loaded, but for the stability of the box, it is preferably flat. Also, on the surface of the loading surface 11, for anti-slip purposes, a known agent having an anti-slip effect may be applied, or irregularities or holes may be provided. It is more preferable that the loading surface 11 is in a mesh form.

[0055] On each side surface 12 of the pallet 1 shown in FIG. 1, a pair of left and right insertion ports 13, 13 are open, and each insertion port 13 communicates with the void inside the pallet 1. Then, by inserting the fork of a forklift (not shown) into the insertion ports 13, 13 and placing and supporting the fork in the void, the pallet 1 can be transported.

[0056] FIG. 2 shows an example of the box used in the embodiment of the carrier of the present invention. The material of the box 2 shown in FIG. 2 is not particularly limited and can be any material such as resin, wood, paper, etc. However, in terms of light weight, the box 2 is preferably made of paper, and in terms of robustness, it is preferably made of cardboard. That is, the box 2 is preferably a cardboard box.

[0057] The shape of the box 2 is not particularly limited and can be a rectangular parallelepiped or a cube of any shape, but a rectangular parallelepiped is preferred. The bottom surface 21 of the box 2 facing the loading surface 11 of the pallet 1 can be rectangular or square, but the bottom surface 21 is preferably square.

[0058] As the box 2, for example, one with a height of 340 mm having a square bottom surface with a side length of 363 mm can be used.

[0059] The box 2 shown in FIG. 2 is provided with a storage portion having a predetermined volume and can store or contain various articles. The type, shape, number, etc. of the articles contained in the box 2 are not particularly limited, and the box 2 can store any articles. Note that the storage portion of the box 2 shown in FIG. 2 can be sealed by a double - door flap.

[0060] As the articles, paper products with a relatively small weight per unit are preferred. Examples of such paper products include tissue paper, toilet paper, etc. In particular, toilet paper in a rolled - up form is preferred. The rolled - up toilet paper may be in a form where thin paper is wound around a cardboard core material, or may be in a form where thin paper is wound without using a core material. Each toilet paper may be individually packaged, or a plurality of toilet papers may be packaged together with a plastic film or the like.

[0061] For example, in the box body 2 shown in FIG. 2, roll-shaped toilet paper individually packaged can be accommodated in its accommodating portion. Specifically, nine roll-shaped toilet papers can be arranged in a 3×3 square shape as one layer, and three layers can be accommodated in the box body 2. In this case, the box body 2 can densely accommodate 27 roll-shaped toilet papers. Thereby, the transportation efficiency can be improved.

[0062] FIG. 3 shows an example of an embodiment of the carrier of the present invention. In FIG. 3, 27 box bodies 2 are densely stacked in three layers with three in a row on the loading surface of the pallet 1 shown in FIG. 1. As shown in FIG. 3, in the carrier of the present invention, since a plurality of box bodies 2 are densely stacked on the pallet 1, the transportation efficiency can be improved.

[0063] As shown in FIG. 3, in the carrier of the present invention, it is preferable that a plurality of box bodies 2 are stacked in a plurality of layers.

[0064] In FIG. 3, nine box bodies 2 form one layer, but the number of box bodies 2 forming one layer is not limited. Also, in FIG. 3, one layer formed by nine box bodies 2 is stacked three times, but the number of stacked layers is not particularly limited.

[0065] The carrier shown in FIG. 3 can be appropriately loaded on a transportation means such as a truck and transported. When using a truck as the transportation means, for example, eight carriers can be arranged in one row and two rows can be loaded.

[0066] The carrier of the present invention may be packaged with a film or a sheet. For example, in the carrier shown in FIG. 3, by packaging the periphery of the 27 box bodies 2 stacked in three layers with a film or a sheet made of plastic or the like, the stability during transportation can be improved and the collapse of the load can be prevented.

[0067] In the carrier of the present invention, a plurality of boxes may be fixed to each other by an adhesive. For example, in the carrier shown in FIG. 3, an adhesive capable of temporarily fixing the boxes 2 is applied to at least a part of the surfaces of 27 boxes 2, and the boxes 2 can be integrated with each other. Thereby, the stability during transportation can be enhanced and the collapse of the load can be prevented. The adhesive is not particularly limited, and any type can be used, but a temporary adhesive that can be peeled off after fixing is preferable.

[0068] Either packaging with a film or a sheet or fixing with an adhesive may be carried out, or both may be carried out.

[0069] FIG. 4 is a conceptual diagram showing the relationship between the loading surface of the pallet and the bottom surface of the box in an example of the carrier of the present invention.

[0070] FIG. 4 shows the loading surface 11 of the pallet 1 of an example of a carrier in which 27 boxes are stacked in three layers as shown in FIG. 3, and the bottom surface 21 of the lowermost box 2 facing the loading surface 11. In the example shown in FIG. 4, the loading surface 11 of the pallet 1 is a square with a side length of 1110 mm, and 9 boxes 2 each having a bottom surface 21 in the shape of a square with a side length of 363 mm are loaded on the loading surface 11.

[0071] In the example shown in FIG. 4, since the total length of the bottom sides of the 9 boxes 2 is 3 × 363 mm = 1089 mm, the length of the side constituting the loading surface 11 of the pallet 1 (1100 mm) - the total length of the bottom sides of the 9 boxes 2 (3 × 363 mm) = 11 mm, and the maximum length of the gap between the boxes 2 is only 11 mm. This is considerably smaller than the length of the bottom side of the box 2, which is 363 mm (for convenience, the gap is exaggerated in FIG. 4). Therefore, the example shown in FIG. 4 satisfies the above formula (1). Thus, in the present invention, the length of the gap between the boxes can be suppressed, so that the boxes can be densely loaded on the pallet, and thereby the transportation efficiency of the boxes can be enhanced.

[0072] Also, in the example shown in FIG. 4, the total bottom area of the 9 boxes 2 is 363 mm × 363 mm × 9 = 1085921 mm2 On the other hand, the total bottom area of the ten boxes 2 is 363 mm × 363 mm × 10 = 1317690 mm 2 And the area of the loading surface 11 of the pallet 1 is 1100 mm × 1100 mm = 1210000 mm 2 This value lies between the bottom area of nine boxes 2 and the bottom area of ten boxes 2. Therefore, the example shown in FIG. 4 satisfies the above formula (2). In particular, in the example of FIG. 4, "i" in the above formula (2) is only about 0.2. That is, in the example shown in FIG. 4, the total area of the voids existing on the loading surface 11 of the pallet 1 is less than 20% of the bottom area of one box 2. Thus, in the present invention, since the area of the voids between the boxes can be suppressed, the boxes can be densely loaded on the pallet, thereby enhancing the transportation efficiency of the boxes.

Industrial Applicability

[0073] The loading carrier of the present invention can achieve high transportation efficiency of the boxes and can be suitably used for loading articles onto a vehicle and unloading articles from the vehicle.

[0074] Also, by densely loading the boxes on the pallet, the gaps between the boxes are reduced, and it is possible to prevent the boxes from collapsing during transportation.

[0075] In recent years, due to problems such as a shortage of truck drivers, when transporting boxes, high transportation efficiency has been demanded. However, according to the present invention, the transportation efficiency can be enhanced and the transportation cost per box can be reduced.
