Description

The present invention relates to a packing box and a packing box mount.

Flat box-shaped and similar thin plate-shaped products have a narrow depth direction in both the height direction and the width direction. Such products include, for example, battery packages packaged in shrink packs. The battery package is packaged in a state in which a plurality of cylindrical batteries having a cylindrical axis in the height direction are arranged in a row in the width direction. Further, when a predetermined number of products flat in the depth direction such as a battery package are stored in a packing box, the products are often stored in a state of being stacked in the depth direction. The packing box is often, for example, an A-type corrugated cardboard box, a so-called "orange box type" square box as described in Non-Patent Document 1 below. In the A-type cardboard box, the height, width, and depth sizes of the products to be stored are defined as the depth, width, and length, respectively.

At the manufacturing site of thin plate-shaped products such as battery packages, product manufacturing, assembly, packaging, and even packaging may be performed consistently. Then, the packed products are collected from the shipping source such as a factory in a warehouse of products waiting to be shipped (hereinafter, also referred to as a terminal), and then delivered to a delivery destination such as each store via a predetermined transportation route. ..

By the way, the number of products delivered to each delivery destination is not necessarily a multiple of the number of all products contained in the packing box. That is, the product is not always delivered in the state of being stored in the packing box after manufacturing. Therefore, in some cases, the products stored in the packing box are picked at the terminal before being shipped. In the picking work, based on the delivery instructions for each delivery destination, you can take out the required number of products from the packing box and adjust the number of products in one packing box, or select the required number of products. Refill it in another box for transportation. The following Patent Document 1 describes a corrugated cardboard blank from which one to at least two corrugated cardboard boxes can be obtained.

When a thin plate-shaped product that is flat in the depth direction, such as a battery package, is packed at the end of the manufacturing process, it is stored in a packing box in a state of being stacked in the length direction without a gap. Therefore, if the products are transported in the packed state at the end of the manufacturing process, there is little possibility that the products will collide with each other in the packing box during transportation and be damaged. However, as described above, the products stored in the packing box at the end of the manufacturing process are often picked in the middle of the transportation route from factory shipment to delivery.

However, if the number of products in one packing box is reduced by picking, a large gap will be created in the packing box, so cushioning material should be stored in the gap inside the packing box so that the products do not collide with each other during transportation. Must be. Therefore, there is a cost related to the cushioning material and a cost for storing the cushioning material.

Further, when refilling into another delivery box, it is necessary to prepare various delivery boxes having different sizes according to the number of products to be stored, and the delivery box is costly. In addition, the packaging box cannot be reused once it is unpacked to refill the product because the opening is sealed at the end of the manufacturing process. Therefore, the cost of the packing box is wasted. It goes against the social demand to promote resource conservation.

In the invention described in Patent Document 1, a plurality of corrugated cardboard boxes can be assembled by dividing one corrugated cardboard blank. However, when a predetermined number of predetermined product packs are stored in a predetermined size packing box at the end of the product manufacturing process, there is an advantage in assembling the packing box using the corrugated cardboard blank described in Patent Document 1. rare. Further, even when the product pack is refilled during the picking work, it is necessary to divide the corrugated cardboard blank and assemble a transport box from the divided corrugated cardboard blank, which requires extra cost. become. The packing box is also wasted.

Therefore, an object of the present invention is to provide a packaging box that contributes to resource saving and facilitates picking work, and a packaging box mount that is the origin of the packaging box.

One aspect of the present invention for achieving the above object is a square packing box in which side surfaces are formed by front, rear, left and right surfaces, and upper and lower surfaces are formed by openable and closable inner flaps and outer flaps. The outer flap is connected to the upper and lower edges of at least one of the left and right surfaces.
The inner flap is connected to at least one of the upper and lower edges of at least one of the front and rear surfaces.
It is provided with a break portion that crosses the outer flap in the left-right direction while crossing each of the left and right surfaces in the vertical direction, and is formed so as to be separable back and forth with the break portion as a boundary.
When the broken portion is broken and separated into two pieces, at least one of the broken pieces is a box body having a side surface and a bottom with the fracture surface of the broken portion as an opening.
The side surface of the box body is composed of left and right surfaces broken in the packaging box and upper and lower surfaces in which the inner flap and the outer flap overlap each other.
In the box body, the outer flap covers the entire upper and lower surfaces.
In the box body , of the two inner flaps continuous to the upper edge and the lower edge of the bottom , at least one of the inner flaps is bent at the edge of the opening while protruding from the opening. At that time, an outer flap region covering the opening of the box body is formed.
When the outer flap region of the box body is bent, the entire surface of the opening is covered with the outer flap region.
It is a packaging box characterized by this.

A packaging box in which the outer flaps are formed symmetrically and the inner flaps are formed vertically symmetrically can also be used. A packaging box may be formed in which a fold line is formed in the outer flap region along the edge of the opening.

Another aspect of the present invention is a mount that is the origin of the packaging box according to any one of the above.
In the packing box, the front surface, the left surface, the rear surface, and the right surface are linearly arranged in a predetermined direction.
The outer flaps are connected to the left side surface and the right side surface in at least one of the upward direction and the downward direction in the packing box.
The inner flaps are connected to at least one of the front surface and the rear surface in the upward direction and the downward direction of the packing box, respectively .
The left surface, the right surface, and the outer flap are formed with the break portion in a direction orthogonal to the predetermined direction.

Further, it is not necessary to consider the vertical relationship when assembling the packing box 1a, and the packing box 1a can be easily assembled.

FIG. 4 shows a stored state of the battery package 100 in the packing box 1a. The packing box 1a shown in FIG. 4 can store 10 sets of 8 battery packages 100 shown in FIG. 1. The eight dry batteries 101 in each battery package 100 are housed in the packing box 1a so as to be lined up in a row in the left-right direction with the cylindrical shaft 102 facing in the vertical direction. Then, 10 battery packages 100 are stored in a state of being stacked in the front-rear direction. The inner dimension (≈W) in the width direction and the inner dimension (≈D) in the depth direction of the packing box 1a are substantially equal to the width w and the height h of one battery package 100, and the length of the packing box 1a. The inner dimension (≈L) in the direction is substantially equal to 10 times the thickness t in the depth direction of the battery package 100 (L≈10 × t). As a result, 10 battery packages 100 are housed in the packing box 1a without any gaps. The broken portion 10 of the packing box 1a is formed at a position where each of the left and right surfaces (3L, 3R) is divided into two equal parts in the front-rear direction, and the packing box 1a is broken by the breaking portion 10 into two pieces. When separated, one piece becomes a shipping box that can hold up to five battery packages 100.

FIG. 5 shows a packaging box 1a in a state of being separated into two pieces. FIG. 5A shows the packaging box 1a in a state of being separated into two pieces (20F, 20B) by the broken portion 10, and FIG. 5B shows the shipping box 20. As shown in FIG. 5A, the packing box 1a according to the embodiment is separated into two pieces (20F, 20B) in the front-rear direction by the breaking portion 10. Then, the rear individual piece 20B is reused as the transportation box 20. As shown in FIG. 5B, the transport box 20 has a rear surface 2B as a bottom surface, a front and rear bisected left surface 3L, a right surface 3R, and an outer flap (4L, 4R) as side surfaces, and a fractured portion 10. The fracture surface is defined as the opening 21. Further, the inner flap 5B protrudes from the opening 21. The region of the inner flap 5B protruding from the opening 21 (hereinafter, also referred to as the outer flap region 51) is formed so as to cover the opening 21 when bent at the edge portion of the opening 21 of the transport box 20. There is. That is, the length L4 of the outer flap region 51 in each of the upper and lower inner flaps 5B is set to be ½ of the depth D of the packing box 1a.

FIG. 6 shows an example of the procedure for using the transport box 20. First, as shown in FIG. 6A, the required number of battery packages 100 are transferred from the 10 battery packages 100 stored in the packing box 1a to the shipping box 20. In the transport box 20, the front-rear direction in the packing box 1a is the depth direction, and the inner dimension in this depth direction is approximately the size when five battery packages 100 are stacked in the front-rear direction (L / 2). ≈ 5 × t). When storing four or less battery packages 100 in the transport box 20, if necessary, a cushioning material may be used to fill the gap in the transport box in the depth direction.

As shown by the alternate long and short dash line, the inner flap 5B is formed with a valley fold line 23 for bending the outer flap region 51 inward of the transport box 20 along the break portion 10. Then, when the required number of battery packages 100 are stored in the transport box 20, the outer flap region 51 is directed toward the inside of the opening 21 with the valley fold line 23 as the base, as shown in FIG. 6 (B). And bend it. As described above, in the packing box 1a, the front-rear length L2 of the rear inner flap 5B on the transport box 20 side is L2 = (L + D) / 2, which is half the length of the front-rear length L of the packing box 1a. It is the length obtained by adding the length of 1/2 of the depth D of the packing box 1a. Therefore, when the upper and lower inner flaps 5B are bent along the folding line 23, the tips of both inner flaps 5B are abutted against each other. Thereby, the opening 21 is covered by the outer flap region 51. When the battery package 100 is shipped in the transport box 20, the transport box 20 may be sealed with an adhesive tape or the like so that the outer flap region 51 does not open. When shipping 6 or more battery packages 100, the required number of battery packages 100 were taken out without breaking the packing box 1a, and the gaps in the packing box 1a in the front-rear direction were filled with cushioning material or the like. Above, the packing box 1a may be used as it is as a delivery box.

As described above, in the packing box 1a according to the embodiment, a predetermined number of flat products such as the battery package 100 in the depth direction can be stored without gaps, and a part of the packing box 1a can be stored in the required number during picking work. It can be reused as a shipping box for refilling products. That is, when the product stored in the packing box 1a is picked and then shipped, it is not necessary to separately prepare a refilling destination box. Since a part of the packing box 1a is reused, the amount of waste can be reduced. Further, even if the number of products stored in the transport box 20 is less than the number that can be stored in the transport box 20, the products in the transport box 20 are less likely to shift in the width direction and the height direction, and the transport box 20 does not easily shift. The gap in the transport box 20 can be filled by filling the minimum cushioning material to the depth of the above, and it is possible to prevent the products from colliding with each other during transportation. Therefore, the packing box 1a according to the embodiment can safely transport the product while contributing to resource saving and cost reduction of the product.

=== Other Examples ===
As a matter of course, the product stored in the packing box 1a according to the embodiment is not limited to the battery package 100. The product may be flat in the depth direction corresponding to the front-rear direction of the packing box 1a, and the width and height of the product may be the same as the width and depth of the packing box. Then, the length in the front-rear direction when a predetermined number of products are stacked in the front-rear direction may be substantially the same as the inner dimension in the front-rear direction of the packing box 1a. Of course, even if the product is not flat in the depth direction, the product can be stored in the transport box 20 separated from one packing box 1a. For example, a flexible and hard-to-break product is unlikely to be damaged even if the products collide with each other during transportation. Therefore, depending on the properties of the product, the width and height of the product may not be equal to the width and depth of the packing box 1a. For products that are flat in the depth direction and whose width and height are about the same as the width and depth of the packing box 1a, as described above, when the shipping box 20 is refilled, a gap is generated in the shipping box 20. However, the gap can be filled with the minimum necessary cushioning material, and even fragile products can be safely transported.

The broken portion 10 may not be formed at a position where the packing box 1a is divided into two equal parts in the front-rear direction. That is, the number of products that can be stored in the transport box 20 can be appropriately set. In any case, the lengths (L2, L4) of the inner flap 5B and the outer flap region 51 on the transport box 20 side may be set according to the size of the opening 21 of the transport box 20 in the vertical direction.

The outer flaps (4L, 4R) do not have to be formed symmetrically. That is, the outer flap (4L or 4R) may be connected only to the upper edge of one of the left and right surfaces (3L or 3R). For example, in the packing box 1b shown in FIG. 7, the outer flap 4R is connected only to the upper edge of the right side 3R. In the example shown in FIG. 7, the left-right width W1 of the outer flap 4R is larger than the width W of the packing box 1b, and the tip end side of the outer flap 4R is the insertion 41. It is also possible not to provide the inner flaps (5F, 5B) in the front-rear direction, but to provide the one having the outer flap area 51 only in the front-rear direction.

The inner flaps (5F, 5B) having the outer flap region 51 do not have to be formed vertically symmetrically. For example, as in the transport box 120 shown in FIG. 8, the outer flap region 51 may be formed only in one of the upper and lower inner flaps (121a, 121b), the inner flap 121a. In any case, the inner flap (5B, 121a) formed on the transport box (20, 120) side may be formed with an outer flap region 51 that covers the opening 21 of the transport box (20, 120). ..

As in the packing box 1c shown in FIG. 9, the outer flap regions 51 may be provided on both the inner flaps (5F, 5B) connected to the front and rear surfaces (2F, 2B). That is, the length (L5, L6) of the inner flaps (5F, 5B) connected to the front and rear surfaces (2F, 2B) is larger than 1/2 of the front and rear length L of the left and right surfaces (3L, 3R). It may be lengthened so that the front and rear inner flaps (5F, 5B) are overlapped with each other as over flaps. Then, while the front-rear lengths (L5, L6) of the inner flaps (5F, 5B) connected to the front-rear surfaces (2F, 2B) are the same, the lengths (L5, L6) are L5 = L6 =. If (L + D) / 2, two shipping boxes 20 of the same size can be obtained from one packing box 1c. Further, if the front and rear positions of the broken portion 10 are appropriately set and the front and rear lengths (L5 and L6) of the front and rear inner flaps (5F, 5B) are changed according to the position of the broken portion 10, two different sizes are used. You can also get the shipping box 20.
