Each of the pivotally attached parts is located below by the crosspieces 18, 19, 20, and 21, so that the right side plate 5 and the left side plate 6 are formed.
When the hinges are bent and folded by the intermediate hinged parts 5 ′ and 6 ′, the respective pivotally connected parts smoothly rotate and the frame body 17 moves the right side plate 5.
The left side plate 6 is designed to be folded so as to be superposed.

In the figure, reference numeral 3'is a hinged portion between the upper flat plate 3a and lower front plate 3b, 17 'is a hinged portion between the top plate 7 and the frame 17, 22 and 23 are handles for carrying, 24 , 25 are mounting pieces for fixing the top plate 7 in a closed state by passing a padlock latch or the like into the holes 24 ', 25' formed in each, and 26 is the rear plate 4
A falling prevention piece for preventing the falling of the container to the outside of the container, 27 is a pivot axis of the front plate 3, and 28 is a pivot axis of the rear plate 4.

[0017]

Since the present invention is configured as described above, the top plate and the upper front plate can be easily folded and the container can be opened greatly, so that it is convenient to load and unload cargo easily. It becomes a folding container.

Also, after releasing the fasteners fixing the rear plate and folding the rear plate onto the bottom plate, then releasing the fasteners fixing the front plate and folding the front plate After folding it on the face plate in a superposed state, the right side plate / left side plate bent by the intermediate hinge part is superposed on this front plate and the top plate is superposed on the right side plate / left side plate via the frame. Since the entire container can be easily folded into a flat state by itself, it is a foldable container that is not bulky and can be stored without taking space when not in use.
