Description

The present invention relates to a container partition member and a container partition structure, and more particularly to a container partition member that does not fall inward and is easy to handle, and a container partition structure using the same.

Foldable containers, cold storage containers, and the like are known as containers in which various articles (food, parts, products, etc.) are stored, stored, and transported. For example, a foldable container is provided with a rectangular bottom plate and a pair of first side plates and second side plates connected to each opposite side (long side / short side) of the bottom plate so as to be able to stand up and down. First, the first side plate is rotated to stand up, and then the second side plate is rotated to stand up, and the standing side plates are locked.

In this type of container, it is necessary to improve the airtightness between the lid and the container body, as well as the airtightness between the side plates. For example, if the heights of the upper end surfaces of the upright side plates are different, a gap is opened between the lower surface of the lid and the upper surface of the side plates, and the airtightness of the container is deteriorated. Further, when only the container main bodies are stacked, the stability of the container main bodies stacked on the upper side may deteriorate.

Therefore, a foldable container having good airtightness, that is, a foldable container in which the height of the upper end surface of the upright side plate does not differ (see, for example, Patent Document 1) has been proposed.

The folding container described in Patent Document 1 has a connecting means for connecting the short side plate and the long side plate at a corner. The connecting means comprises a protrusion protruding inward (concave side of the container) from the inner surface of the end portion of the long side plate, and a notch formed at the end portion of the short side plate 40. The protrusion and the notch are formed in a tapered shape, and the plates on both sides are pulled and fixed by the wedge effect when the protrusion and the notch are engaged with each other. This enhances the airtightness between the plates on both sides.

By the way, in this type of container, the storage form of the article is diversified, and for example, it is considered to partition the space inside the container into upper and lower parts by a partition member. Here, many of the partitioning members that partition the inside of the container up and down are so-called box-shaped ones, which are complicated to install inside the container, and the volume of the partitioning member itself reduces the internal volume of the container. There are many challenges.

The present invention has been proposed in view of such conventional circumstances, and although it has a simple structure, it can be easily mounted on a container, is easy to handle, and is in a good mounting state. It is an object of the present invention to provide a partition member for a container capable of reliably partitioning a space in a container, and further, an object of the present invention is to provide a partition structure of the container.

In order to achieve the above-mentioned object, the partition member for a container of the present invention is a partition member for a container having a hollow double wall structure, and is a bottom plate and a pair of side plates connected to each other via hinges on both sides thereof. The hinge is formed by linearly compressing a partition member having a hollow double wall structure, and on the back surface side of the hinge, the bottom plate and the side plate retract with an inclination of 10 ° to 30 °. An inward fall prevention portion that regulates the inward fall of the side plate by abutting against each other is formed on each end edge of the bottom plate and the side plate that are continuously provided, and the inward fall prevention portion is formed in the bottom plate and the side plate. It is composed of a plurality of abutting portions formed on the side plates, and these abutting portions are formed as stepped portions formed by bending the bottom plate or the side plates, and the end surface of each abutting portion is an inclined surface. It is characterized by being.

The partition member for a container of the present invention has a simple structure in which side plates are connected to the bottom plate via hinges on both sides, and can be installed simply by erecting the side plates and inserting them into the container. The side plate does not fall inward due to the function of the inward fall prevention unit, and the difficulty of handling due to the careless inward fall of the side plate is eliminated.

According to the present invention, a partition member for a container, which has a simple structure, is easy to handle, can be easily mounted on a container, has a good mounting state, and can reliably partition the space inside the container, and a container. It is possible to provide a partition structure of.

Hereinafter, embodiments of the container partition member and the container partition structure to which the present invention is applied will be described in detail with reference to the drawings.

First, a container in which the internal space is partitioned by the container partitioning member of the present invention will be described. As shown in FIGS. 1 and 2, the container 1 is composed of a box-shaped container body 11 capable of accommodating articles and a lid 12 that closes an opening of the container body 11.

The container main body 11 is composed of a bottom plate 21 having a rectangular planar shape constituting the bottom surface, a pair of short side plates 22 and 23 constituting a side wall, and a pair of long side plates 24 and 25. The short side plates 22, 23 and the long side plates 24, 25 are foldably connected to the bottom plate 21. When folding the container body 11, as shown in FIG. 2, the short side plates 22 and 23 are folded inward, and then the long side plates 24 and 25 are folded so as to be overlapped with the folded short side plates 22 and 23. ..

Further, the container main body 11 has a connection mechanism for connecting the upright short side plates 22, 23 and the long side plates 24, 25 at the corners of the container main body 11, and the upright short side plates 22, 23 and the long side plates. It is equipped with a lock mechanism that locks 24 and 25, and the assembled state is maintained by these connection mechanisms and lock mechanisms.

The container 1 is, for example, a cold storage container for refrigerated foods and frozen foods. In that case, the bottom plate 21, the short side plates 22, 23, the long side plates 24, 25, and the lid 12 have a hollow double wall structure. And the heat insulation is maintained. A heat insulating material such as a foaming material may be inserted into the bottom plate 21, the short side plates 22, 23, and the long side plates 24, 25 having a hollow double wall structure.

The partition member 30 is mounted inside the container 1 to partition the internal space of the container 1 into a plurality of parts. Specifically, as shown in FIG. 3, for example, by stacking two partition members 30 and inserting them into the container 1, the space in the container 1 is divided into upper and lower parts.

FIG. 4 shows a state in which two partition members 30 are stacked inside the container 1, and by installing the two partition members 30, a lower accommodation space partitioned by the lower partition member 30 and a lower accommodation space. An upper accommodation space partitioned by the upper partition member 30 is formed. That is, the container 1 can be configured in two stages, and articles can be stored in each space.

Next, the configuration of the partition member 30 will be described. As shown in FIGS. 5 and 6, the partition member 30 has side plates 32 and 33 hinges 34 on both sides (long side in this example) of the bottom plate 31, respectively. It is connected through 35. FIG. 5 is a diagram showing a state in which the partition member 30 is spread out, and FIG. 6 is a diagram showing a state in which the side plates 32 and 33 are raised. When partitioning the internal space of the container 1, the side plates 32 and 33 are used in a raised state as shown in FIG.

Like the container 1, the partition member 30 also has a hollow double-walled structure formed so as to have a space between two resin sheets. For example, as shown in FIG. 6, the partition members 30 are formed on the side plates 32 and 33. Mechanical strength is ensured by forming the slit-shaped ribs 32a and 33a. The slit-shaped ribs 32a and 33a are formed as recesses by compression, and two resin sheets on the front and back are welded in this portion. By alternately forming the hollow double wall structure and the compression portion, the strength is greatly improved.

The hinges 34 and 35 are formed by linearly compressing a partition member 30 having a hollow double wall structure. In the hinges 34 and 35, the hollow double wall structure is crushed and two resin sheets are welded and integrated, so that the hinges 34 and 35 can be bent like one resin sheet. Therefore, in the partition member 30, the side plates 32 and 33 can be raised as shown in FIG. 6 by bending the hinges 34 and 35 from the expanded state shown in FIG.

The compression of the hinges 34 and 35 is performed using a mold, but it is preferable to give an inclination to the mold to be used in consideration of ease of die cutting, mold strength, and the like. For example, by providing an inclination of about 10 ° to 30 ° on both sides with respect to the pushing direction of the mold, the mold can be released well and the mold strength can be improved. If the partition member 30 is formed so as to be tilted with respect to the mold at the time of compression, it is possible to impart the inclination to only one side of the mold.

FIG. 7 is a cross-sectional view taken along the line xx of FIG. 5, which is an enlarged view of the vicinity of the hinge 35. The hinges 34 and 35 are formed by compression on the inner surface side of the partition member 30, and on the back surface side of the hinges 34 and 35, the bottom plate 31 and the side plates 32 and 33 are inclined (inclined by about 10 ° to 30 °). ) Is retreating. Therefore, as shown in FIG. 8, on the back surface side of the hinges 34 and 35, a space is formed at the corners when the side plates 32 and 33 are raised. The corners of the container 1 often have a curved surface shape, and the partition member 30 cannot be laid without a gap unless the hinges 34 and 35 of the partition member 30 have such a shape.

If the side plates 32 and 33 in the raised state of the partition member 30 collapse, it becomes difficult to maintain a stable stacked state, and it becomes difficult to secure a space for accommodating the articles. For example, when the side plates 32 and 33 are housed in the container 1 in a raised state, the outer surface of the side plates 32 and 33 of the partition member 30 is supported by the inner wall surface of the container 1, so that the side plates 32 and 33 are supported. Does not fall (fall out) toward the outside.

On the other hand, since the insides of the side plates 32 and 33 are not supported by the container 1, they tend to fall down carelessly. The inward tilting (inward tilting) of the side plates 32 and 33 hinders the formation of the space partitioned by the partition member 30, and the upper partition member at the tip of the side plates 32 and 33 of the lower partition member 30. When considering the configuration of supporting the bottom surface of 30, there is also a problem that stacking becomes impossible.

Therefore, in the partition member 30 of the present embodiment, the inward falling prevention portion 40 is provided in the connecting portion between the bottom plate 31 and the side plate 32 and the connecting portion between the bottom plate 31 and the side plate 33 to prevent the side plates 32 and 33 from falling inward. I am doing it. In the case of the present embodiment, inward fall prevention portions 40 are provided at three locations in the joint portion between the bottom plate 31 and the side plate 32 and three locations in the joint portion between the bottom plate 31 and the side plate 33, for a total of six locations.

Each inward fall prevention portion 40 is composed of an abutting portion 41 on the bottom plate 31 side and an abutting portion 42 on the side plates 32 and 33 sides, and each of the abutting portions 41 and 42 bulges inward. It is formed as a rectangular stepped area.

FIG. 9 is an enlarged view showing the vicinity of the inward fall prevention portion 40. For example, in the abutting portion 41 of the bottom plate 31, a rectangular region near the end edge along the hinges 34 and 35 of the bottom plate 31 is bent around. It is formed as a stepped portion that seems to have been lifted inward (upward). The rectangular upper surface 41a of the abutting portion 41 is formed as a stepped surface protruding upward (that is, in the abutting portion 41, the outer surface of the bottom plate 31 recedes inward from the main surface of the bottom plate 31. The lower surface 41b is substantially flush with the upper surface 31a of the portion of the bottom plate 31 where the abutting portion 41 is not formed. The end surface 41c on the side plates 32, 33 side of the abutting portion 41 faces the abutting portion 42 of the side plates 32, 33 in a rising state in a shape lifted from the bottom plate 31, and has an inclined surface inclined at approximately 45 °. Has been done.

The same applies to the abutting portion 42 of the side plates 32 and 33, and the stepped portion where the rectangular region near the edge of the side plates 32 and 33 along the hinges 34 and 35 is bent around and protrudes inward. (That is, in the abutting portion 42, the outer surface of the side plates 32, 33 is formed so as to recede inward from the main surface of the side plates 32, 33). The rectangular inner side surface 42a of the abutting portion 42 is formed as a stepped surface protruding inward, and the outer surface 42b is the inner side surface 32a of the portion of the side plates 32 and 33 where the abutting portion 42 is not formed. , 33a, which are almost flush with each other. The end surface 42c on the bottom plate 31 side of the abutting portion 42 faces the abutting portion 41 of the bottom plate 31 so as to project from the side plates 32 and 33, and is an inclined surface inclined at approximately 45 °.

In the inward fall prevention portion 40 having the above configuration, when the side plates 32 and 33 are in the rising state, the end surface 42c of the abutting portion 42 provided on the side plates 32 and 33 becomes the end surface of the abutting portion 41 provided on the bottom plate 31. Contact with 41c. Since each of the end faces 41c and 42c is formed as an inclined surface inclined at approximately 45 °, the side plates 32 and 33 are held in a state of standing up at a substantially right angle when they come into contact with each other. Further, the contact between the end faces 41c and 42c prevents the side plates 32 and 33 from falling further inward, and prevents the side plates 32 and 33 from falling inward.

Further, the space inside the container 1 is partitioned by stacking the partition members 30 in the state where the side plates 32 and 33 are raised. At this time, the tip surfaces 32b and 33b of the side plates 32 and 33 of the lower partition member 30 are formed. It is supported by abutting on the bottom surface 31a of the bottom plate 31 of the upper partition member 30. Therefore, it is preferable that the mechanical strength in the vicinity of the tip surfaces 32b and 33b of the side plates 32 and 33 is high.

Therefore, in the partition member 30 of the present embodiment, the bending portions 32d and 33d are provided at the tip portions of the side plates 32 and 33 at three locations corresponding to the inward fall prevention portions 40, respectively. The bent portions 32d and 33d are formed by projecting the vicinity of the tip surfaces 32b and 33b of the side plates 32 and 33 inward, similarly to the inward fall prevention portion 40.

By forming the bent portions 32d and 33d at the tip portions of the side plates 32 and 33 in this way, the mechanical strength of the tip portions of the side plates 32 and 33 is improved and the contact area abutting against the bottom plate 31 is expanded. As a result, the stacked state of the partition members 30 becomes stable.

The contact structure between the tips of the side plates 32 and 33 of the lower partition member 30 and the bottom plate 31 of the upper partition member 30 is not limited to this, and as a reference example, for example, the tips of the side plates 32 and 33 of the lower partition member 30. The portion may be shaped so as to enter the abutting portion 41 formed on the upper bottom plate 31.

10 and 11 show another example of the contact structure between the tip ends of the side plates 32 and 33 of the lower partition member 30 and the bottom plate 31 of the upper partition member 30. The configuration of the inward fall prevention portion 40 is the same as the example shown in FIG. 9, but in addition to this, a positioning protrusion 51 is provided on the back surface side of the abutting portion 41 on the bottom plate 31 side. Further, at a position corresponding to the abutting portion 41 on the bottom plate 31 side, the tip portions of the side plates 32 and 33 of the lower partition member 30 are formed so as to project.

In a state where the partition members 30 having such a configuration are stacked, as shown in FIG. 11, the tip ends of the side plates 32 and 33 of the lower partition member 30 are in the recesses on the back surface side of the abutting portion 41 on the bottom plate 31 side. The position is regulated by the positioning protrusion 51 provided on the back surface of the abutting portion 41 on the bottom plate 31 side. As a result, for example, when the cargo is stacked in the upper partition member 30, even when the bottom plate 31 is bent due to the weight of the cargo, the positioning protrusion 51 can prevent the bottom plate 30 from falling inward. Therefore, it is possible to make the stacked state of the partition member 30 more stable by setting such a stacked state.

As described above, the partition member 30 of the present embodiment has a simple structure, is easy to handle, can be easily mounted on the container, and is in a good mounting state. Therefore, by using the partition member 30 of the present embodiment, it is possible to reliably partition the space in the container 1.

Although the embodiments to which the present invention has been applied have been described above, it goes without saying that the present invention is not limited to the above-described embodiments, and various changes may be made without departing from the gist of the present invention. It is possible.
