Description

Description: TECHNICAL FIELD The present invention relates to a stacking container, and more particularly to a technique for effectively preventing the lower container from being spread out by stacking.

[Background Art] Conventionally, in a stacked container in which the bottom of a container body having an open top is stacked so as to close the opening of the lower container body, the containers are stacked in multiple stages, or heavy objects are stored in the container to be stacked. However, there has been a problem that the lower container is pushed out in the width direction and enters too deeply into the lower container so that the upper container cannot be removed. On the other hand, in the case of vertically stacked containers, side wall ribs are formed to increase the vertical load on the plate-shaped side walls, and the partitions are erected and held to partition the containers to distinguish the contents. However, there is a problem in that the inner volume of the container is reduced in order to form the side wall rib for increasing the vertical load and the holding portion for vertically holding the partition in a protruding manner on the inner surface of the container.

[Object of the Invention] The present invention has been made in view of the above problems,
The purpose is to avoid forming a holding portion for the partition other than the side wall ribs without reducing the internal capacity,
An object of the present invention is to provide a stacked container in which the lower container does not spread in the width direction while surely partitioning.

DISCLOSURE OF THE INVENTION A stacking container of the present invention is a stacking container in which a bottom portion 2 of a container body 1 having an upper opening is stacked so as to close an opening 3 of a lower container body 1, and an inner surface of the container body 1 An insertion protrusion 11 is formed at an upper end of a side wall rib 4 formed in the opening 3 and opposed to the width direction of the opening 3 at a distance from the inner side surface of the container body 1, and between the insertion protrusion 11 and the inner side surface of the container body 1. A receiving step portion 16 is formed in the partition 5, a mounting portion 14 is formed on both sides of the upper end of the partition 5, an insertion hole 15 is formed in the mounting portion 14, and an insertion hole 15 is inserted in the insertion protrusion 11. A partition 5 is installed between the side wall ribs 4 and 4 facing each other, and the depth of the receiving step portion 16 and the height of the mounting portion portion 14a inserted therein are made substantially equal to each other so that the upper surface of the partition 5 and the upper surface of the insertion protrusion 11 are formed. And are formed to be substantially flush with each other,
With such a configuration, the above object is achieved. That is, by utilizing the side wall ribs 4 that enhance the strength of the side wall 6 by detachably installing the partition 5 that does not extend in the width direction of the opening 3 between the side wall ribs 4 and 4 that face each other in the width direction of the opening 3. Thus, the partition 5 for partitioning the inside of the container body 1 can be attached, and it is not necessary to project a holding portion for standingly holding the partition 5 other than the side wall ribs 4 to the inner surface of the container body 1, Since the partition 5 does not expand without reducing the internal capacity, the opposing side walls of the container body 1 are not spread by the stacking load, and stable stacking can be performed as expected, and the container body 1 In order to mount the partition 5 between the side wall ribs 4 and 4 provided on the inner side surface, the insertion holes 15 at both ends of the partition 5 are inserted into the insertion protrusions 11 of the opposing side wall ribs 4 and face each other at the partition 5. Side wall 6,6 There was prevented from trying to spread, while avoiding the basic functions of stacking containers according to the side walls 6,6 spread is inhibited,
In such a case, the depth of the receiving step portion 16 and the height of the mounting portion 14a inserted therein are substantially equal to each other, and when the partition 5 is installed, the upper surface of the partition 5 and the insertion protrusion 11 of the upper end of the side wall rib 4 are inserted. Are substantially flush with each other, and the state in which the partition 5 is erected in a predetermined manner can be easily determined. For example, it is possible to avoid a erection failure such as pinching a small article at the bottom of the partition 5, and the upper part of the partition 5. In this case, a space that is flush with the opening 3 of the container body 1 can be formed, and the partition 5 and the insertion protrusion 11 are flush with each other to enhance the appearance.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

The container A is a molded product of synthetic resin, and an upper flange 7 is extended outward at the periphery of the opening 3 of the container body 1 having an open top. A fitting peripheral piece 9 is hung from the outer circumference of the bottom plate 8 of the container body 1 over the entire circumference thereof, and the outer peripheral dimension of the fitting peripheral piece 9 is substantially matched with the size of the opening 3. Further, a lower flange 10 extends substantially horizontally above the bottom plate 8. Then, the insertion peripheral piece 9 of the upper container A is replaced with the lower container A.
The lower flange 10 of the upper container A
Is mounted on the upper flange 7 of the lower container A so that the containers A and A can be stacked vertically.

Side wall ribs 4 ... Are integrally formed with the side wall 6 on the inner surface of the side wall 6 of the container body 1 to increase the vertical load on the side wall 6.
An insertion protrusion 11 is formed on the upper end of the side wall rib 4. As shown in FIG. 1, the partition 5 is made of a thin plate member 12 and a thick reinforcing bar member 13 integrally molded with the synthetic resin so that the partition member 5 does not extend or contract in the length direction and is configured as a strength member. is there. At the upper part of both ends of the partition 5 in the longitudinal direction, the mounting portion 1
4 is formed and the fitting hole 14 is penetrated through the insertion hole 14. Then, by inserting the insertion hole 15 of the partition 5 into the insertion protrusion 11 of the side wall rib 4 to detachably install the partition 5, the side wall rib 4 that enhances the strength of the side wall 6 is utilized.
A partition 5 for partitioning the inside of the container body 1 can be attached, and it is not necessary to form a holding part for standingly holding the partition 5 other than the side wall ribs 4 on the inner surface of the container body 1 so as to project.
The manufacturing (mold manufacturing) surface is improved, the volume of the container body 1 is not reduced, and the partition 5 does not extend,
The opposing side walls of the container body 1 are not spread by the stacking load, and stable stacking is possible as expected.

In this case, the upper surface 5a of the partition 5 and the upper surface of the insertion protrusion 11 are substantially flush with each other. That is, as shown in FIGS. 3 and 4, the receiving step portion 16 is formed between the insertion protrusion 11 and the inner side surface of the container body 1, and the insertion hole 1 is inserted into the insertion hole 1.
Although the partition 5 is installed between the opposing side wall ribs 4 and 4 by inserting the partition 5, the depth of the receiving step portion 16 and the height of the mounting portion 14a inserted therein are substantially equal to each other. 5
And the upper surface of the insertion protrusion 11 are substantially flush with each other. Then, as shown in FIG. 3, in the stacked state of the containers A, A, a gap is formed between the insertion peripheral piece 9 and the partition 5.

[Advantages of the Invention] In summary, according to the present invention, the insertion protrusion is formed on the upper end surface of the side wall rib formed on the inner side surface of the container body and facing the width direction of the opening at a distance from the inner side surface of the container body. A receiving step is formed between the insertion protrusion and the inner surface of the container body, mounting portions are formed on both sides of the upper end of the partition, insertion holes are formed in the attachment portion, and insertion holes are formed in the insertion protrusion. A partition is installed between the side wall ribs that are inserted and face each other, and the depth of the receiving step portion and the height of the mounting portion that is inserted into the receiving step portion are approximately the same, and the upper surface of the partition and the upper surface of the insertion protrusion are substantially flat. Therefore, in order to mount the partition between the side wall ribs provided on the inner surface of the container body, the insertion holes at both ends of the partition are inserted into the insertion protrusions of the opposite side wall ribs to face each other. To prevent the space between the side walls from expanding and to allow the side wall to expand. In such a case, the depth of the receiving step and the height of the mounting part to be inserted into the receiving step are almost equal to each other, while preventing the basic function of the stacking container from being hindered. , The upper surface of the partition and the insertion protrusions at the upper ends of the side wall ribs are substantially flush with each other, and it is possible to easily determine the state in which the partition is erected in a predetermined manner. It is possible to avoid the above, and it is possible to form a space in the upper part of the partition that is flush with the opening of the container body, and the partition and the insertion protrusion are flush with each other, so that the appearance can be improved. .
