Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a large folding container used for storing cases such as beer and soft drinks, moving luggage, or agricultural products such as fruits and vegetables. The present invention relates to a large pallet container having a high side wall plate for storing a large amount of articles.

[0002]

2. Description of the Related Art Conventionally, a folding wall is provided on a bottom plate which constitutes a pallet, and when the folding wall is used, the folding wall is erected to form a container, and when not in use, the folding wall is folded on the upper surface of the bottom plate to reduce the bulk. What was done is Kaikaihei 3-9
It is known from 1925. This actual Kaihei 3-9
The one disclosed in Japanese Patent No. 1925 has a configuration in which an auxiliary wall body is integrally formed with a bottom plate along a pair of opposite sides of the bottom plate.

[0003]

However, in the case where the auxiliary wall body is integrally formed along a pair of opposing sides of the bottom plate as described above, it can be used only as a pallet container and only the bottom plate is used. Can not be used as a pallet whose upper surface is a flat surface, and can also be used as a bottom plate of a pallet container whose upper part is a container using the pallet currently used. There wasn't. Further, in the prior art, in manufacturing, a bottom plate was formed with a mold in which an auxiliary wall body was integrally formed, and a mold different from a mold for a general pallet was required. Moreover, if the size of the bottom plate is different,
It was necessary to form a plurality of types of bottom plates in which the auxiliary wall bodies were integrated.

Moreover, in the above-mentioned conventional example, since the auxiliary wall body is formed only along a pair of opposite sides of the bottom plate, the auxiliary wall is formed on the side of the auxiliary wall body among the four side wall bodies. Although the side wall body is placed directly on the body, the side wall body is erected on the bottom plate on the remaining pair of opposite sides of the bottom plate. However, when the contents are put in such a container, for example, when the pickles are stored in a bag, a larger load or internal pressure is applied to the lower side of the side wall of the container. In the non-existing portion, the same maximum load or maximum internal pressure as that applied to the auxiliary wall body is applied near the bottom plate at the lower end portion of the side wall body. Therefore, unlike the auxiliary wall body, the side wall body is not integrated with the bottom plate and is merely placed, so that the lower portion of the side wall body may greatly squeeze outward.

The present invention has been made in view of the above-mentioned problems of the prior art, and its object is to use it as a pallet container which is assembled with a simple structure and whose upper part is a container, or is compact. It is possible to fold it into a pallet, and it is also possible to use only the bottom plate as a normal pallet. Also, it can be used as the bottom plate of a pallet container whose upper part is a container using the currently used pallet. It is also possible to manufacture a bottom plate for a pallet container by using a mold for manufacturing an ordinary bottom plate, and a lateral load applied to the four side wall bodies when the contents are put therein. Another object of the present invention is to provide a pallet container that can be made small and can prevent the side wall body from being pushed out.

[0006]

In the pallet container of the present invention, auxiliary wall bodies 3 are detachably attached by bolts 4 along four sides of an upper surface of a rectangular bottom plate 2 having a fork insertion portion 1 for a forklift. The side wall body 6 is attached to the auxiliary wall body 3 by fitting the shaft 7 provided at the lower portion of the side wall body 6 into the bearing portion 5 provided on the auxiliary wall body 3 so as to be rotatable and vertically movable.
And the fall prevention leg portion 8 provided on the lower end portion of the side wall body 6 can be inserted into the locking groove 9 provided on the auxiliary wall body 3 from above, and the side wall bodies 6 are adjacent to each other in an upright state. The side walls 6 are detachably connected to each other, and the four side walls 6 can be stacked on the bottom plate 2 in a state where the side walls 6 are disconnected from each other. By adopting the configuration, the problems of the conventional example described above are solved and the object of the present invention is achieved.

[0007]

According to the present invention having the above-described structure, however, when used, it can be used as a pallet container by erecting the side wall bodies 6 and connecting the adjacent side wall bodies 6 into a container shape. When it is not done, the side wall body 6 is laid down and the bottom plate 2
It is made compact by stacking on top. Then, the auxiliary wall bodies 3 are detachably attached with the bolts 4 along the four sides of the upper surface of the rectangular bottom plate 2 having the fork lift insertion portion 1 for the forklift, respectively.
On the other hand, since the auxiliary wall body 3 is a separate body and is attached by the bolts 4, the same bottom plate as the ordinary bottom plate can be used, and when the bolts 4 are removed, the bottom plate 2 becomes the same as an ordinary pallet. It is now possible to use.
Further, the auxiliary wall body 3 is erected by the bolts 4 along the four sides of the upper surface of the bottom plate 2 so that the maximum lateral load applied by the contents when the side wall body 6 is erected and assembled in a container shape. The maximum internal pressure is applied to the auxiliary wall body 3 attached by the bolt 4 and is supported at this portion, so that the side wall body 6 is prevented from being pushed out.
