Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foldable simple container.

[0002]

2. Description of the Related Art Conventionally, there has been known a simple container in which a metal frame is fixed on a pallet, and front, rear, left and right side plates are foldably assembled on the pallet via the metal frame.

[0003] There are roughly two types of such containers, one is a type in which four side plates are completely separated from a metal frame, and the other is a type in which the lower end of each side plate is always pivoted. It is a form that is attached to a metal frame.

[0004] In the former case, that is, the side plate separated type container,
When assembling the side plates, it is necessary to lift the side plates one by one by hand, insert the side plates into the metal frame, and stop them, so that the operation is complicated. When the container is folded and returned, the side plate may be lost.

[0005] In the latter, ie, pivot type container, assembling the side plates is simpler than erecting the side plates that are laid down, and the risk of loss is small as compared with the separation type. However, when repairing a damaged side plate or the like, it takes time and effort to remove the side plate from the metal frame.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems in a conventional simple container.
An object of the present invention is to provide a simple container having a new structure in which a side plate can be easily assembled simply by erecting a laid side plate, and when necessary, each side plate can be easily removed from a metal frame.

[0007]

SUMMARY OF THE INVENTION The above-mentioned problems are solved by an upper lid,
In a simple container having a metal frame fixed on a pallet and front, rear, left and right side plates erected on the pallet via the metal frame, the front and rear side plates are:
A pair of pins protruding in the left-right direction of the container provided at predetermined positions at lower ends of both side surfaces thereof, and a pair of vertically long holes provided a predetermined distance above the lower ends of both lower corners on the outer surface thereof, Each of the left and right side plates has a pair of pins protruding in the front-rear direction of the container provided at the lower end of both side surfaces, and the metal frame has a height capable of accommodating four side plates. And vertical walls that are connected to each other at the four corners, and each vertical wall before and after the metal frame is made of a wall that forms a step in the vertical direction, and its lower wall is stretched outward with a width that allows the side plate to be placed. The lower wall and the intermediate horizontal portion are connected between the left and right ends and the left and right vertical walls through a middle horizontal portion through which a vertical gap for accommodating the front and rear direction pins is provided. The upper wall portion is located at a position corresponding to the vertically long hole on both left and right end sides of the inner surface thereof, and the inside of the container is A simple container, characterized in that each of the left and right vertical walls of the metal frame has a vertical slit for accommodating the left and right pins at a position closer to the center by a predetermined distance from both ends thereof, Can be solved.

[0008] In the simple container according to the present invention (hereinafter referred to as the present container), the upper surface of the intermediate horizontal portion has a height corresponding to the thickness of about two side plates from the pallet surface, and before and after standing upright. The height (height) of the side plate is lower than the left and right side plates by the height of the upper surface of the intermediate horizontal portion. Further, the height of the bottom surface of the vertical slit is substantially equal to the height of the upper surface of the intermediate horizontal portion. Furthermore, since both side surfaces of the left and right side plates are assembled by contacting the inner surfaces of both ends of the front and rear side plates, each side of the metal frame has a length sufficient to accommodate each side plate thus assembled.

When folding the side plate of the container constructed as described above, the pins in the front-rear direction are inserted into the vertical gap, and the pins in the left-right direction are dropped into the vertical slits, respectively. Each side plate may be stacked flatly in the space formed by the metal frame in the order of the left, right, left and right side plates and the front and rear or rear front side plates from below.

When the container space is formed by raising the side plates of the container, each of the front and rear side plates is rotated around a pin in the left-right direction, and each projection is formed while fitting the projection on the inner surface of the upper wall into the elongated hole. Place the side plate upright on the middle horizontal, then
The left and right side plates may be turned around the pins in the front-rear direction to stand upright on the pallet, and the upper ends of the side plates may be fixed to each other with the fasteners. In this case, the front and rear side plates are prevented from floating by the projections fitted in the vertically long holes, and the left and right side plates are prevented from floating by fixing the upper ends to the front and rear side plates with the stoppers. The upper end of each side plate assembled in a box shape is covered with an upper lid and fixed with a rubber band or the like.

In the container having the above structure, the upper portion of the vertical slit is open, and the container is easily deformed when an external force is applied around the slit. Also, the heads of the pins dropped in the slit in the front-rear direction and the left-right direction are exposed outside the container. For these, for example, a corner fitting is provided to cover the left and right ends of the front and rear vertical walls and the peripheral portions of the slits of the left and right vertical walls, and a vertically long gutter-like straddling the slit on the outer surface of the corner fitting overlapping the left and right vertical walls. A bulge may be provided to cover the head of the pin.
