Thus, according to the present invention, there is provided a foldable container having a pallet and a plurality of side plates erected on the pallet, wherein at least one side plate is provided on the pallet. There is provided a collapsible container, which is rotatably mounted on the inside of the container.

In the assembly type container according to the present invention, a long metal frame having a U-shaped cross section is fixed to a lower end of a side plate erected on a pallet, and a long metal rod is used. It is preferable to form a space to be inserted.

In the assembling type container according to the present invention, it is preferable that a band-shaped metal fitting having a stepped cross-sectional shape is fixed on the pallet, and lower metal fittings are erected at four corner positions on the pallet. preferable.

In the prefabricated container according to the present invention, the side plate erected on the pallet has a long metal frame in a space formed by a long metal frame having a U-shaped cross section fixed to the lower end thereof. It is preferable that a round bar is inserted and rotatably attached to lower metal fittings erected at four corner positions on the pallet.

In the prefabricated container according to the present invention, one of the side plates erected on the pallet is vertically divided,
It is preferable to have a lower panel mounted on the pallet and an upper panel rotatably attached to the outside of the container by a hinge above the lower panel.

In the prefabricated container according to the present invention, it is preferable that one of the side plates erected on the pallet is removable.

[0012]

In the assembling type container according to the present invention, the side plate erected on the pallet is rotatably attached to the lower bracket fixed on the pallet, so that it can be easily assembled in use. After use, individual side plates can be folded without separating them.

In the prefabricated container according to the present invention, the side plate is inserted by inserting a long metal rod into the space formed by the long metal frame having a U-shaped cross section fixed to the lower end of the side plate. It can be easily attached to the lower metal fittings standing upright at the four corners on the pallet.

In the prefabricated container according to the present invention, one of the side plates is divided into upper and lower parts, and has a lower panel and an upper panel. The upper panel is rotatable only to the outside of the container with respect to the lower panel. In the case of adopting the mounted structure, it is possible to carry out the operation of loading products into the container while keeping the upper panel open to the outside of the container.

In the case of the prefabricated container according to the present invention, in which one of the side plates erected on the pallet is removable, the product is put in the container with the front panel open. Loading work can be performed.
