Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to nested synthetic resin containers that can be stacked.

[Conventional technology]

Conventional containers of this type include one with a metal handle as shown in FIG. 1, and one with a left-right interchangeable type when nested as shown in FIG. 2.

[Problem that the invention attempts to solve]

However, the former has the disadvantage that the metal handle 2 is set in the synthetic resin container 1, which increases the cost, and the metal handle 2 rusts, making it unusable in fields where rust is averse.

The latter method places a heavy burden on the worker, as the stacking work must be done while being careful to ensure that the left and right sides of containers 1 are the same, and when nesting work, care must be taken to ensure that the left and right sides are reversed one after the other. In addition, there is a recess 1a inside.
This has the disadvantage that stored items may fall apart or become a dead space.

[Means for solving problems]

This invention solves the above-mentioned drawbacks of conventional containers, and by attaching and detaching the bottom plate to the container body separately, stacking and nesting can be performed, and it can be made inexpensively from synthetic resin without using metals. The purpose of the present invention is to provide a synthetic resin container that can be stacked without considering the left-right relationship of the containers, and is a container that widens toward the end of the upper opening and is made of flexible synthetic resin. In such a container, the opposing parts of the vessel wall are separated from the other parts of the vessel wall except for the upper part, and the bottom part is folded under the bottom wall, and the part is separated from the other part of the vessel wall, and the part is separated from the other part of the vessel wall by a predetermined interval in the above-mentioned opposing direction. The present invention is characterized in that stoppers facing each other and locked to each other are formed on the bottom wall and the bottom portion, respectively, and a protrusion is provided on the lower surface of the bottom.

Hereinafter, the present invention will be explained in more detail based on the embodiments shown in FIGS. 3 to 6.

In FIGS. 3 and 4, reference numeral 3 denotes a rectangular container that widens toward the opening at the top, and is integrally molded using elastically deformable synthetic resin.

The four corners of the container 3 form part of the container wall,
A separation wall 6 is provided which is completely separated from the bottom wall 4 and separated from the side wall 5 except for the upper part. As shown in FIG. 4, the separation wall 6 consists of a bottom part 61 at the corner, and a side wall part 62 that includes a part of the side wall and is separated from the side wall 5 on both sides but continuous at the top. On the other hand, they are stacked at different levels on the bottom.

Therefore, when this container 3 is filled with items such as fruits, the stack separation walls 6 at the four corners will bend outward along the diagonal direction due to the load of the items due to its flexibility. and protrudes from the side wall 5, creating a gap A between the separation wall 6 and the side wall 5.

In order to restrict the amount of protrusion of the separation wall 6, stoppers 4a and 6 are provided on the opposing surfaces of the bottom wall 4 and the bottom 61, respectively.
1a is formed and the bottom part 61 of the separation wall 6 is displaced below the frontage flange 3a, the stopper 61
a is adapted to be laterally engaged with the inside of the stopper 4a. Another stopper 4b is formed on the lower surface of the bottom wall 4 on the inner side of the stopper 61a to prevent excessive inward bending of the separation wall 6.

Furthermore, in order to prevent inward lateral slippage during stacking,
A protrusion 61b is formed on the lower surface of the bottom portion 61, and holes 3a1 into which the protrusion 61b can fit are bored at the four corners of the opening flange 3a.

7 is a reinforcing rib provided below the opening flange 3a.

FIG. 5 shows the container 3 packed with items and stacked in two tiers.

When this container 3 is filled with items, the separation walls 6 at the four corners protrude and their bottoms 61 are displaced below the opening flange 3a. Resting on the flange 3a, the upper container 3 is supported on the lower container 3 by a separating wall 6.

Furthermore, during this stacking process, the protrusion 61b engages with the hole 3a1 of the opening flange 3a, so even if the number of items in the upper container 3 decreases, the separation wall 6 will shift inward and the stacking posture will collapse. Never.

In addition, the protrusion 61b may be formed in a curved shape when viewed from above and may be made to circumscribe the outer edge surface of the four corners of the opening flange 3a.
1 does not need to be provided.

When this container 3 is empty, there is no protrusion of the stack separation wall 6 and the outer surface of the side wall portion 62 coincides with the outer surface of the side wall 5, so that the containers can be nested as shown in FIG.

In the above embodiment, the separation walls 6 are provided at the four corners, but they may be provided on one side wall and only one pair on the opposite side wall, or they may be provided on each of the two pairs of side walls facing each other. You can.

In addition, in the above embodiment, the separation wall 6 is made to protrude when stacking, but conversely, the shape where the separation wall 6 protrudes, that is, the shape shown in FIG. The wall 6 may be configured to be bent inward.

[Effect of idea]

As described above, according to this invention, the opposing parts of the vessel wall form a separation wall that is connected to the other part of the vessel wall at the top, and during normal operation, this separation wall protrudes from the side wall or is flush with the side wall. In the former case, by simply pulling out the item from the nested state, or in the latter case, by simply stuffing the item, the stacked position can be obtained naturally. This can significantly reduce the burden on workers.

Moreover, since the container of this invention is made of synthetic resin, it is inexpensive and does not have the problem of rusting.Since there is no need to make unevenness on the inside surface, there is no problem of dead space or product falling apart, which is different from conventional containers. It is possible to obtain a container with high practical value that eliminates all drawbacks at once.
