Description

[Detailed description of the invention]

[0001] The present invention is a transport container capable of stacking containers in the same direction (hereinafter, referred to as stacking), but changing the direction of the containers to be overlapped (hereinafter, referred to as nesting), and having a large plane size. (Large box) and a container (half box) having a plane size obtained by dividing the plane size into approximately two parts can be stacked on each other regardless of the direction of the box.
The present invention relates to a transport container having a structure in which a load is not unevenly distributed with respect to a load and can be stacked in a stable state.

[0002]

2. Description of the Related Art Among containers of the same type, as a container capable of stacking and nesting depending on the structure of the container itself, for example, a transportation container disclosed in Japanese Utility Model Publication No. 63-40453 is known. In this container, a bulging portion (pocket portion) bulging outward from the opening edge of the container to the middle and high portion of the container is formed on the side wall of the rectangular container asymmetrically with respect to the opposing side wall. By nesting, one of the upper and lower containers is rotated 180 degrees in the plane direction so that the upper and lower containers are staggered so that the bulging portions are staggered (hereinafter, this stacking method is referred to as 180). Degree rotation method). However, in this container, the upper container must always be rotated by 180 degrees with respect to the lower container, as described above, and thus has the following problems.

That is, when a kanban, a card, or the like for displaying contents is attached to the outside of one side wall of the container, the display device is turned upside down in the upper and lower stages. In this case, the contents could not be checked from one direction, which was inconvenient at the time of storage in a warehouse. Also, in the case where a container containing contents such as parts is flowed through an assembling line, for example, as described above, if the containers are stacked in a 180-degree different direction for each stage, the containers are directly placed on the line in order from the top. In this case, the orientation of the contents differs from container to container, so that the workability is poor, and this also hinders automatic assembly by a robot.
For this reason, there is a problem in that the stacked containers must be turned every other one and lowered on the line, which is troublesome.

On the other hand, as disclosed in Japanese Utility Model Laid-Open Publication No. 2-102343, the containers are stacked in a normal position, and the upper container is replaced with the lower container. A container that can be nested by rotating it 180 degrees in a plane direction has been proposed (hereinafter, this stacking method is referred to as same-color stacking).

In this container, supporting legs (stacking support portions) on the opening edge of the container protruding from the outer surface of the side wall and a part of the side wall are bulged outward at point-symmetric positions of opposing side walls of the rectangular container. This is a transport container in which a pocket portion (nesting fitting portion) is formed so that the support leg portion can be put out and stored.

[0006] In general, in a container that can only be stacked, a container having a large planar size (hereinafter referred to as a large box) and a container in which the planar size of the large box is equally divided, for example, to one half ( (Hereinafter referred to as a half box) can be stacked with each other by raising the bottom of the large box and stacking the large box on the half box, or by fitting the stacking allowance of the large box without interference. One side of the opening edge (flange) of the half box or the opposite side is dropped into the half box. However, in containers that allow stacking and nesting, bins and half boxes are not stacked with each other regardless of orientation.

[0007]

[Problems to be solved by the invention] In order to stack (up and down) mutually in a large box and a half box of the same color stacking, it is necessary to install a stacking support part close to the corner of one container. . This is because the corner portion support is most effective in compressive (stacking) strength, and the stacking support is evenly arranged, and stable stacking is possible.

[0008] In a half-box, it is necessary to have a stacking support portion of four points or more so that a load is more evenly distributed when stacked on a large box.
If it is less than 3 points support, the span between the points is large,
Difficulty in stable stacking. In addition, in order to stack a large box on a half box, a stacking support portion is provided on both sides of the large box (side surfaces having the same length as the half box) as much as possible outside, and the stacking support portion is There must be two or more points near both sides.

3 In the case of a rectangular (plan view) container, FIG.
Pattern of stacking half boxes on a large box as shown in 4.
(1) and pattern for stacking large boxes on half boxes (2)
, As shown in FIG. This is because both the large box and the half box have the same color stacking structure, and the arrangement of the stacking support portion and the nesting fitting portion has directionality. A and B of the large box 21 and C and D of the half box 22 indicate directions, and arrows indicate the case where the half box is stacked on the large box and the large box is stacked on the half box, respectively. Therefore, from the viewpoint of work efficiency, a container that can be reliably stacked in a stable shape without any direction in any of the above patterns is most desirable.

[0010] 4. In addition, since both the large box and the half box have the same color stacking structure, a nesting fitting portion for accommodating the stacking support portion is naturally required on the side of the container, and the stacking support portion comes over the nesting fitting portion. Also, the stacking mechanism cannot be performed. And so on.

An object of the present invention is to provide a transport container having the same color stacking structure in which the upwardly opened flat surface has a rectangular shape. A large box having a large plane size and a half box having a half plane size thereof are used for load support. It provides a transportable container that is stackable in a stable form with each other (up and down), has excellent compressive strength when stacked in multiple layers, and has excellent workability that can be stacked regardless of direction. is there.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the transport container of the present invention will be described with reference to the drawings. In the figure, the bottom mesh, side patterns, signs, handle portions, and the like are omitted. The large box 1 is a rectangular container which is inclined so that the long side walls 2 and 3 and the short side walls 4 and 5 extend slightly outward from the bottom 6 toward the opening edge 7 as shown in FIGS. , 3 each have two S portions 8 and two N portions 9 near each corner, and the short side walls 4 and 5 have two S portions each near each corner near the corner.
Part 10 (slightly wider than S part 8) and two N parts 11
(Slightly wider than the N portion 9) are integrally formed.

In FIG. 12, the positions of the S parts 8, 10 below the opening edge 7 are indicated by dotted lines. As shown in FIG. 12, the S portion and the N portion of the opposing side wall are substantially point-symmetric with respect to the center O of the container. The S portions 8, 10 provided on the outer side surface of the side wall of the container have two vertical ribs hanging down from the opening edge 7 and being connected to the horizontal ribs 12 and extending further downward. Are formed. S part,
It is a stage toward the outside, and has an intermediate receiving portion 13 (which corresponds to the lower side of the lateral rib 12) and a receiving portion 14 at a lower end. ), The receiving portion 14 at the lower end becomes a receiving portion at the time of stacking.

At the time of stacking, the portion below the lower end 14 of the S portion of the container fits inside the upper part of the lower container as a stacking margin. The N portion bulges a part of the side wall to the outside, dents the inner surface of the container, and forms a pocket portion, and can store below the intermediate receiving portion of the S portion during nesting. At the center of the bottom part 6, a bottom surface reaching the lower part of the long side wall parallel to the short side wall is raised on the inner side, and a concave part 15 which is recessed on the outer side is provided. And the opening edge is stored, so that the stacking margin is fitted to the upper inside of the half box to enable stacking.

The half box 1A is inclined so that the opposing long side walls 2A, 3A and short side walls 4A, 5A extend slightly outward from the bottom 6A toward the opening edges 7A, 7B as shown in FIGS. It is a rectangular container whose plane size is approximately equal to the plane of the large box 1 divided into two, and whose long side walls 2A, 3A are almost the same length as the short side walls 4, 5 of the large box. And the lengths of the short side walls 4A and 5A of the half box and the lengths of the opening edges thereof are almost half the lengths of the long side walls 2 and 3 and the length of the opening edges of the large box. 1
It has become.

On the long side walls 2A and 3A, two S portions 10 and two N portions 11 are provided for each side wall near the corner.
However, on the short side walls 4A and 5A, two S portions 8 and two N portions 9 are integrally formed near each corner near each corner. In FIG. 15, S below the opening edge 7A
The positions of the parts 8 and 10 are indicated by dotted lines. Further, the arrangement of the S portion and the N portion is at a point symmetric position with respect to the side wall opposite to the center O of the container, and the same color stacking as in the large box.

S parts 8, 10 provided on the outer surface of the side wall of the half box
Has a stepped outer side like a large box, and has a receiving portion 13 at an intermediate portion and a receiving portion 14 at a lower end. At the time of stacking, a portion below the lower end 14 of the S portion of the container is fitted to the upper inside of the lower container as a stacking margin. N part 9.1
1 has a pocket portion formed on the inner side surface of the container as in the case of the large box, so that a portion below the intermediate receiving portion of the S portion can be stored during nesting.

Further, a part of the S portion provided on the outer surface of the side wall of the half box has a lateral rib 1A from the opening edge 7A as shown in the S portion 8 of FIG.
Up to 2A, one vertical rib hangs down from the horizontal rib 12A to form two vertical ribs. Also in this case, an intermediate receiving portion 13 (coincident with the lower surface of the horizontal rib 12A) and a lower end receiving portion 14 are provided. The arrangement of the S and N parts in the half box is shown in FIG.
Are arranged as shown in FIG.
If no distinction is made between the parts, they are located at substantially the same positions as the parts S and N in the large box with respect to the container corner. Side walls 2A, 3A and 4A, 5
The arrangement of the S portion 8 and the N portion 9 of 4A and 5A of A is the reverse of the arrangement of the S portion 8 and the N portion 9 of the opposing side walls 2 and 3 of the box.

S and S of the large box and the half box shown in FIGS.
The arrangement of the part and the N part corresponds to FIG. FIGS. 20 and 21 show an example of a pattern when half boxes are stacked on the illustrated large box. The figure corresponds to the pattern of FIG. In the front side view of FIG. 20, the upper half box 1A is supported by the right S portion 8 as shown in FIG. A vertical rib is provided on a side wall of a portion located below the S portion 8 of the half box, though it does not overlap with the S portion of the lower large box 1, and is strengthened against load. In the left side view of FIG.
Support stacking. S section 10 of the lower box
The upper half box S section 10 is on top.

In both the large box and the half box, a vertical rib reaching the vertical rib 12 from the opening edge to the horizontal rib 12 is provided at an appropriate position separately from the portion S outside the side wall. A transverse rib is provided between the two to strengthen the wall against a load. In FIG. 20, the S portion 8 supporting the stacking of the upper half box does not overlap with the S portion of the lower large box, but the large box is formed by vertical ribs connecting the opening edge and the horizontal ribs 12 with the opening edge and the side wall body. In FIG. 21, the S portion 10 of the upper half box is strengthened against the load.
And the S section 10 of the lower large box is in the state where it is most difficult to support the overlapping load. In contrast to FIG. 4, the stacking of the half box to the large box is performed by four points of the S section representing the vicinity of each corner. Supported and stable stacking. Further, since the lower portion of the upper half box below the S portion lower end 14 is fitted inside the upper portion of the lower box, the half box does not slip or slip off from the box.

FIGS. 22 and 23 show an example of a pattern when a large box is stacked on the illustrated half box. The figure corresponds to the pattern of FIG. As can be seen from the pattern diagram of FIG. 8, there is no S part supporting the stacking in the front side view of FIG. 22, but in the left side view of FIG. 23, the left and right S parts 10 of the large box have the opening edge 7A of the lower half box. Riding on top supports stacking. The S portion of the large box that supports the stacking of the large boxes overlaps the S portion 10 of the half box at the time of stacking, which is the best arrangement for supporting the load.
Since the large box is supported at four or more points in the S section near each corner (in the figure, near the corner of the short side wall), the large box is stuck in a form that is stable against load support. In addition, since the concave portion 15 in the center of the bottom straddles the opening edges of the two lower half boxes and stores them, the bottom large box excluding the concave portion 15 does not interfere with the opening edge of the half box. The stacking allowance fits inside the upper part of the half box, and the stacking is performed in a stable state without slipping or slipping.

As can be seen from the illustrated embodiment and the pattern diagrams of FIGS. 4 to 11, the stacking of the transport container according to the present invention has an S portion near the container corner and is effective for compressive strength when stacked in multiple stages. The container is reinforced, and the stacking is supported by the S portion, but at least one or more S representing each corner portion (including the vicinity) is provided.
Parts are supported by four or more points and are stable against load support.
It is understood that the portion and the S portion of the lower container often overlap each other, and stacking that does not force the load support is performed.

The container of the present invention is made of a synthetic resin (including one modified with rubber) and is integrally molded by injection molding or other known molding methods. As the synthetic resin, a thermosetting resin can be used in addition to a thermoplastic resin, and plastics are generally used. Of course, pigments, dyes, fillers, antioxidants, and others can be used as the synthetic resin. Also, the container of the present invention
