Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a transportable rectangular container (hereinafter, also simply referred to as a “container”) that can be stacked and stacked.

[Prior art and its problems]

The rectangular containers for transportation, in which each side wall is inclined so as to expand slightly outward toward the opening edge, may be piled up (hereinafter referred to as “nesting”) when not in use so that it does not become bulky. The container can be stacked in multiple stages by containing contents such as parts (hereinafter referred to as "stacking").
Say. ) There are things that can be done.

As described above, a container capable of nesting and stacking is conventionally well known, for example, from Japanese Utility Model Publication No. 63-40453, and it is connected to a side wall of a rectangular container for transportation from an opening edge of the container. It is also well known that the bulging portion is formed asymmetrically with respect to opposite side walls. This is configured such that by stacking the upper container on the lower container by rotating it 180 degrees in a horizontal plane, the bulged portions of the upper and lower containers are staggered and stacking is possible. However, in the above-mentioned conventional container, as described above, the upper container has to be always rotated by 180 degrees with respect to the lower container, so that there is the following problem.

In other words, if, for example, a kanban or a card for displaying contents is attached to the outside of one side wall of the container, the display tools are opposite to each other in the upper and lower tiers. In this case, the contents could not be confirmed from one direction, which was inconvenient during storage in a warehouse. In addition, for example, when a container in which contents such as parts are stored is flown to an assembly line, if the containers are stacked in different directions by 180 degrees for each stage as described above, the container remains as it is. If the items were placed on the line in order from the top, the orientation of the contents would differ from container to container, resulting in poor workability and obstacles to automatic assembly by robots. For this reason,
Stacked containers have to be turned every other piece and dropped onto the line, which causes a problem of poor workability and trouble.

Further, in order to clarify the direction of the container, JP-A-60-1
There is known a plastic container having a two-color finish, which is capable of stacking and nesting, as shown in Japanese Patent Publication No. 9515, but this does not solve the above problems.

Therefore, the applicant can stack the upper container as it is (without needing to rotate 180 degrees) with respect to the lower container, as in the application for utility model registration in Japanese Utility Model Application No. 1-9752. We proposed a rectangular container for transportation that can be nested by rotating the upper container 180 degrees with respect to the above container, and improved its handleability.

That is, the transportation rectangular container pertaining to the utility model registration application is
A rectangular container in which each side wall is inclined so as to spread slightly outward toward the opening edge, and at a point-symmetrical position of the opposing side walls, a supporting leg projecting from the outer surface of the side wall and riding on the opening edge of the container,
It is characterized in that a part of the side wall is bulged outward so as to be recessed in the inner surface of the container to form a pocket portion into which the supporting leg portion can be fitted.

Therefore, when the upper container is placed on the lower container as it is, the supporting leg of the upper container is supported on the opening edge of the lower container and is in a stacking state, while the upper container is 180
When the container is rotated once and placed, the supporting leg portion of the upper container is fitted into the pocket portion of the lower container to be in a nesting state.

However, in the rectangular container for transportation, when stacking the upper container on the opening edge of the lower container and sliding the upper container on the opening edge of the lower container for stacking, the stacking is performed as shown in FIG. As shown, the supporting leg b of the upper container fits into the pocket a of the lower container during the slide, and the upper container cannot be slid unless the upper container is lifted up, which deteriorates workability. There was a problem.

[Means for solving problems]

In order to solve the above problems and to further improve the workability and handleability of the transportation rectangular container, the transportation rectangular container of the present invention has a side wall inclined so as to expand toward the opening edge. The upper surface of which is formed to be flat in the same plane, and a wide pocket portion having a depth substantially half that of the container formed by bulging outward the inner wall at the corner of the side wall and the wide pocket. First supporting leg / pocket part formed of a combination with a narrow supporting leg part disposed on the outer wall of the side wall near the center adjacent to the center part and a wide supporting leg part disposed on the outer wall of the corner part of the side wall, and the wide supporting leg part. The second support leg formed by combining the inner wall of the side wall near the center adjacent to the support leg portion of the container with a narrow pocket having a depth approximately half that of the container formed outwardly.
Or a first supporting leg / pocket portion, and a pair of the second supporting leg / pocket portions are arranged to face at least a corner portion of the opposing side wall, or the first supporting leg / pocket portion. Are arranged at least at the corners of the same side wall, and the second supporting leg / pocket part is arranged on the side wall opposite to the side wall so as to face the first supporting leg / pocket part, respectively. It was done.

[Action]

When the upper container is slid for stacking, the large supporting legs near the corners of the upper container can be slid without sliding into the small pockets of the lower container during the slide operation, which facilitates stacking.

[Embodiment 1] FIGS. 1 to 3 show Embodiment 1 of the rectangular container for transportation according to the present invention.
Indicates. This rectangular container for transportation is a container in which long side walls 1 and 2 and single side walls 3 and 4 are inclined so as to spread slightly outward toward an opening edge 5, and a long side wall 1 whose center point O is point-symmetrical. On a part of the long side wall 2, a set A composed of a supporting leg 6A and a pocket 7A, a set B composed of a supporting leg 6B and a pocket 7B, a set C composed of a supporting leg 6C and a pocket 7C and a supporting leg 6D.
D sets each of which includes a pocket portion 7D and a pocket portion 7D are formed.

The supporting leg portions 6A to 6D project outward from the outer walls of the long side walls 1 and 2, and the upper half portions 6A1 to 6D1 thereof are formed in a stepped shape so that the protruding amount thereof is larger than that of the lower half portion. ing.

In addition, the pockets 7A to 7D are formed so that the inner walls of the long side walls 1 and 2 adjacent to the supporting legs 6A to 6D are bulged outwardly to form a recess in the inner wall of the container, so that the pockets 7A to 7D have about half the size of the container. The pocket portions 7A to 7D having a depth are formed, and the supporting leg portions 6A to 6D respectively have the same set of pocket portions 7A to 6D as the supporting leg portions 6A to 6D when nesting.
It is formed in a size that can be fitted into 7D.

Further, the supporting leg portions 6A and 6B arranged to face the opposing long side walls 1 and 2 are formed so that the width dimension thereof is narrower than that of the supporting leg portions 6C and 6D. The width dimensions of the pocket portions 7A and 7B arranged to face each other are smaller than the width dimensions of the pocket portions 7C and 7D. The wide support legs 6C and 6D and the wide pockets 7C and 7D are both arranged so as to be closer to the corner of the container, and thus the wide support leg 6 is provided.
The narrow leg portions 6A, 7B narrower than C, 6D and the narrow pocket portions 7A, 7B narrower than the wide pocket portions 7C, 7D are both longer than the long side wall 1 from the corner of the container. Two
Of the supporting legs 6C and 6D having a wide width and the pockets 7C and 7D having a wide width.

Furthermore, the opening edge 5 of the transporting rectangular container is formed so that its upper surface is the same plane and has a flat surface without steps.

In the transporting rectangular container configured as described above, by placing the upper container on the lower container without rotating it, the upper container can be placed on the opening edge 5 of the lower container as shown in FIG. Support legs 6A, 6B, 6C, 6 of the upper container
D is supported and can be stacked. When the upper container is slid on the lower container for such stacking, the narrow supporting legs 6A, 6B of the upper container are separated by the wide pockets 7C, 7D of the lower container. Wide pockets 7C, 7 because they are formed closer to the parts
Since the wide supporting legs 6C and 6D of the upper container are not wider than the pockets 7A and 7B of the lower container without fitting into the D, the pockets 7A and 7B are also narrow.
It is possible to slide smoothly without fitting into B and facilitate stacking work.

Further, as described above, since the opening edge 5 of the container is formed into a flat plane without steps or the like, stacking work becomes easier, and the upper container is located above the opening edge 5 of the lower container. Can be slid more smoothly. In particular, if the opening edge 5 of the container has unevenness such as a step, it is impossible to stack a large number of containers in a stable state, and the stacked containers may collapse. Since the opening edge 5 is formed in a flat plane without steps or the like, it is possible to stack a large number of containers in a stable state, and thus the stacked containers are not collapsed, and The storage and storage space for the container can be reduced.

In addition, the supporting legs 6A, 6B, 6C, and 6D have long side walls 1 and 2.
In addition, since two are formed for each, a stable stacking state is obtained, and the supporting legs 6A, 6B, 6C, 6D of the upper container and the supporting legs 6A of the lower container,
Since 6B, 6C and 6D are arranged substantially vertically when stacking, the upper container is mainly supported by the supporting legs 6A, 6B, 6C and 6D of the lower container. Therefore, it is possible to stack more containers in multiple stages without causing damage such as buckling of the containers.

In addition, place the upper container in the horizontal plane with respect to the lower container.
When rotated by 0 degrees and placed, each pocket 7 of the lower container
In A to 7D, the supporting legs 6A to 6D of the upper container can be fitted into each other for nesting. At this time, the upper half portions 6A1 to 6D1 of the supporting legs of the upper container ride on the opening edge 5 and the amount of fitting is limited.

The supporting legs and the pockets of the side walls 1, 2, 3, 4 are
The arrangement or the number as shown in this embodiment is not limited, and another arrangement or a larger number may be provided.

[Embodiment 2] Embodiment 2 shown in FIGS. 4 and 5 is different from Embodiment 1 in the arrangement of the supporting leg portions 6A to 6D and the pocket portions 7A to 7D on the long side walls 1 and 2. In this Example 2
, The wide supporting leg portion 6C near the corner of the long side wall 1,
6D is formed, and the wide supporting leg portions 6C and 6D are fitted into the long side wall 2 on the side opposite to the long side wall 1 at positions facing the wide supporting leg portions 6C and 6D formed on the long side wall 1, respectively. Wide pockets 7C to 7D to be obtained are formed. Then, near the center of the long side wall 1 of the wide supporting leg portions 6C and 6D, narrow pocket portions 7A and 7B narrower than the wide pocket portions 7C to 7D are arranged, and the wide pocket portion 7C is also provided. , 7D near the center of the long side wall 2, supporting legs 6C,
Narrow supporting legs 6A and 6B each having a width narrower than that of 6D are arranged. The narrow pocket portions 7A and 7B of the long side wall 1 are arranged to face the narrow support leg portions 6A and 6B formed on the long side wall 2 on the opposite side of the long side wall 1, respectively. . In this way, stacking and nesting can be performed in the same manner by changing the arrangement of the supporting legs and the pockets.

[Embodiment 3] In the embodiment shown in FIGS. 6 and 7, in addition to the long side walls 1 and 2, the supporting portions 8A, 8B, 8C and 8D and the supporting legs are fitted into the single side walls 3 and 4, respectively. Possible pockets 9A, 9B, 9C,
9D is formed, and by doing so, when stacking, the upper container is supported by the supporting legs 8A, 8B, 8
Since C and 8D are also supported on the lower container, a more stable and load-bearing stacking becomes possible.

[Effect of device]

As described above, the transport container of the present invention has good handleability because it can be stacked without rotating the upper container with respect to the lower container, and when the upper container is slid for stacking. In addition, since the supporting legs do not needlessly fit into the pockets of the lower container and can be smoothly slid, workability for stacking is good.

By forming the pocket portion by bulging the inner wall adjacent to the supporting leg portion outward, the pocket portion bulging outward acts as a reinforcing rib. This makes it possible to prevent problems such as deterioration of the washing performance of the container due to the convex portions of the mold, and facilitates mold design.

The opening edge is formed on a flat plane without steps,
Since the upper container is configured to be able to slide more smoothly on the opening edge of the lower container, the stamping work becomes easier. Also, if there are irregularities such as steps on the opening edge of the container, it is not possible to stack a large number of containers in a stable state, and the stacked containers may collapse, but the transport container of the present invention is
Since the opening edge of the container is formed into a flat plane without steps or the like, it is possible to stack a large number of containers in a stable state, and therefore the stacked containers do not collapse, and In addition, the storage and storage space for the container can be reduced.

By integrally forming the adjacent side wall portions of the pocket portion and the supporting leg portion with each other, there is no gap between the adjacent pocket portion and the supporting leg portion, so that the cleaning property of the container is improved and the strength is improved. Further, since the structure of this portion is simplified, the mold can be made to have a simple structure, and the productivity can be improved.
