[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a foldable simple container.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a simple container of a type in which a metal frame is fixed on a pallet and front, rear, left and right side plates are assembled so as to be foldable on the pallet via the metal frame is known.
[0003]
There are roughly two types of such containers, one is a type in which the four side plates are completely separated from the metal frame, and the other is a metal frame that is always pivoted at the lower end of each side plate. It is a form to install.
[0004]
In the former, that is, the side plate separation type container, when assembling the side plates, it is necessary to lift the side plates one by one by hand and insert them into a metal frame, which is complicated. Also, when the container is folded and returned, the side plate may be lost.
[0005]
In the latter case, that is, the pivot type container, the side plate can be assembled easily by raising the side plate that is laid down, and is less likely to be lost than the separate type. However, it takes time and effort to remove the side plate from the metal frame when repairing the damaged side plate or the like.
[0006]
[Problems to be solved by the invention]
The object of the present invention is to solve the above-mentioned problems in the conventional simple container, so that the side plate can be assembled simply by raising the side plate that is laid, and each side plate can be easily removed from the metal frame when necessary. It is possible to provide a simple container having a new structure.
[0007]
[Means for Solving the Problems]
In the simple container comprising an upper lid, a metal frame fixed on the pallet, and front, rear, left and right side plates that are foldable on the pallet via the metal frame, The side plate has a pair of pins projecting in the left-right direction of the container provided at predetermined positions on the lower end portions of both side surfaces, and a pair of vertically elongated holes provided at a predetermined distance above the lower ends of the lower corner portions on the outer surface. The left and right side plates each have a pair of pins projecting in the front-rear direction of the container provided at the lower ends of both side surfaces, and the metal frame has a height that can accommodate four side plates. The vertical walls that are erected on each side are connected to each other at the four corners, and each vertical wall before and after the metal frame consists of a wall portion that forms a step in the vertical direction. Connected to the upper wall through an intermediate horizontal portion projecting toward the The inter-horizontal portion has a vertical gap between the left and right ends and the left and right vertical walls to accommodate the front and rear pins, and the upper wall portion corresponds to the vertical elongated holes on the left and right ends of the inner surface. And a vertical slit that accommodates the left and right pins at a position closer to the center by a predetermined distance from both ends of the vertical walls. This can be solved by a simple container characterized by this.
[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 a plate thickness of about two side plates from the pallet surface, and the front and rear side plates standing upright on the upper side. The height (height) is lower than the left and right side plates by the height of the upper surface of the intermediate horizontal portion. 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. Further, since both side surfaces of the left and right side plates are assembled in contact with 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 the side plates so assembled.
[0009]
When folding the side plate of the container configured as described above, the front and rear pins are dropped into the vertical gap, and the left and right pins are dropped into the vertical slit, and the left and right pins are Alternatively, the side plates may be stacked flatly in the space formed by the metal frame in the order of the right and left side plates and the front and rear or rear front side plates.
[0010]
When the container side walls are formed by raising the side plates of the container, the front and rear side plates are rotated around the pins in the left and right direction, and the projections on the inner surface of the upper wall portion are fitted into the vertically long holes, and the side plates are placed in the middle. What is necessary is just to make it stand upright on a horizontal part, and then to turn each side plate on either side around the pin of the front-back direction to stand upright on a pallet, and to fix the upper end part of each side plate mutually with a fastener. In this case, the front and rear side plates are prevented from being lifted by the protrusions inserted into the vertically long holes, and the left and right side plates are prevented from being lifted by fixing the upper ends of the left and right side plates to the front and rear side plates with a stopper. An upper lid is placed on the upper end of each side plate assembled in a box shape and fixed with a rubber band or the like.
[0011]
In the container having the above-described configuration, the upper part of the slit in the vertical direction is open, and is easily deformed when an external force is applied around the slit. Further, the heads of the pins in the front-rear direction and the left-right direction dropped into the slit are exposed to the outside of the container. For these, for example, corner metal fittings that cover the left and right end portions of the front and rear vertical walls and the peripheral portions of the slits of the left and right vertical walls are provided, and a vertically long bowl shape that spans the slits on the outer surface of the corner metal fitting that overlaps the left and right vertical walls. A bulging portion may be provided to cover the head of the pin.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
The following (A) can be mentioned as a preferred embodiment of the present invention.
(A) The simple container described above, wherein at least one of the side plates is divided into two in the vertical direction with a dividing line as a boundary, and an upper part of the side plate can be reversed outwardly by a hinge provided on the dividing line.
[0013]
According to the present embodiment, since at least one of the side plates has a folded structure, the contents can be easily loaded into the container by inverting the upper part of the side plate to the outside of the container. And convenient.
[0014]
