Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a transportation container equipped with a partition.

[Prior art and its problems] A protrusion is asymmetrically formed on the opposing side walls of a rectangular container that is open at the top, extending from the opening edge to the middle part of the container, and when these are stacked in the same direction, the lower container A transport container is one in which the upper container is stacked in a nested manner, and when the upper container is rotated 180 degrees in a horizontal plane and stacked, the upper container can be stacked on the opening edge of the lower container. It has been known for a long time. That is, as an example is shown in FIGS. 6 and 7, the swelling protrusions 3a,
4a and the expansion protrusions 5b and 6b are formed asymmetrically, and when these containers are stacked in two or more tiers, when the upper container is in the same direction as the lower container, the inside of the expansion protrusion of the lower container is The expanded protrusions of the upper container fit together and the two containers overlap in a nesting manner (hereinafter referred to as nesting), but the upper container is rotated 180 degrees in a horizontal plane relative to the lower container. When stacked, the bottom surface of each swelling part of the upper container rests on the opening edge 7 of the lower container, so that the upper container can be stacked while securing space for storing items in the lower container. This is called "stucking".

However, when the upper container is rotated 180 degrees and stacked left and right oppositely to the lower container as described above, each expanded protrusion 3a, 4 of the upper container is placed on the opening edge of the lower container.
Since the bottom surfaces of the containers a, 5b, and 6b rest directly on each other, they shift laterally even when subjected to slight vibrations or shocks, making it impossible to obtain stable stacking. When a partition plate is provided, conventionally, the pair of ribs 9, 9 on the inner wall surface of the container forming the groove 8 for supporting the partition plate are located at the locations where the swollen protrusions 3a, 4a, 5b, and 6b are located. Therefore, it was necessary to form it on the inner surface of each of the swollen protrusions. For this reason, it becomes necessary to make the length of the partition plate longer at this swelling part than at other parts.
There was a problem in that because partition plates of different lengths had to be prepared, it became time-consuming to manage and assemble them.

[Means for Solving the Problems] Accordingly, the present invention has a protrusion formed on the opposing side walls from the opening edge of the rectangular container to a high part in the container, and a bottom surface of the protrusion on the outer surface of the container. In addition to extending the extension part in a more drooping manner, a stopper is provided protrudingly on the outer surface of the other opposing side wall, and a pair of ribs that hold both ends of the partition plate are installed at a portion lower than the swelling part on the inner wall surface of the container. It was formed in a limited manner.

[Operation] When the upper container and the lower container are stacked in opposite left and right directions, the lower end of the side wall of the upper container fits into the lower container, and the lower end surfaces of the extension legs are placed above the left and right opening edges of the container. It is placed in contact with the Therefore, the containers on the upper tier fit tightly into the containers on the lower tier and do not shift laterally, so that the containers can be stacked firmly in the vertical direction.

[Example] Figures 1 to 5 show an example of the transportation container of the present invention. In this container, opposing side walls 2a, 2
In b is a swelling protrusion 3 from the opening edge 7 to the middle and high part of the container.
a, 4a, 5b, and 6b are formed asymmetrically. And a pair of ribs 9, 9 that hold both ends of the partition plate 10.
are formed on the inner wall surface of the container below the expanded protrusions 3a, 4a, 5b, and 6b. Reference numeral 11 indicates an extending leg extending downwardly from the bottom surface of each of the expanded protrusions 3a, 4a, 5b, and 6b on the outer surface of the container. The dimensions are determined. Therefore, once fitted together, the containers in the upper and lower tiers can be firmly stacked without shifting from side to side. Since the lower end surface of the extending leg 11 is located slightly above the lower end surface of the container, the side walls 2a, 2b of the upper container,
The lower end portions of the extending legs 13a and 13b fit into the lower container, and the lower end surface of the extending leg 11 comes into contact with the opening edge of the lower container. At this time as well, both containers are maintained in a stacked state without shifting from side to side.
Reference numeral 12 denotes a stopper protruding from the outer surface of the other opposing side walls 13a and 13b, and the stopper of the upper container comes into contact with the opening edge 7 of the lower container during nesting, so that both containers fit together during nesting. The amount is regulated accordingly.

[Effect of the invention] Since a partition plate of a constant length can be used without changing at the expanded protrusion, the structure and assembly of the partition plate can be simplified, contributing to cost reduction.

Furthermore, there is an advantage that even if the upper and lower containers are stacked with their left and right sides reversed, they can be stacked firmly without shifting laterally.
