2. Description of the Related Art Hitherto, in the manufacture of relatively large storage containers such as clothing boxes, they have been manufactured by being divided into respective members such as a container body, an extraction unit and a lid, but these are assembled into a set. When one package was used, the whole was very large and had to be transported by air.

[0003] For this reason, the cost of packing and transporting each unit is high, and it is necessary to prepare a wide space for transportation, sales and use.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention eliminates the above-mentioned disadvantages of the storage container, and is extremely easy to handle for manufacturers, dealers, and users by reducing the size during packaging and transportation and increasing the size during use. and Turkey to provide a highly practical container is an object.

At the same time, upon disposal when not in use,
It is an object of the present invention to make it easy to disassemble a large extraction box or cover frame.

[0006]

According to the present invention, a wall plate having an appropriate height is erected on the back and left and right side surfaces of an extraction box having a front opening, and an intermediate position of the height of the wall plate. A notch is formed at the corner portion of each wall plate up to the groove portion while forming a concave groove portion so that each wall plate can be folded inward,
On the other hand, the front and back sides are opened to form a concave groove at an intermediate position of the height of the right and left side plates of the covering body including the top plate and the left and right side plates, so that the groove can be folded inward, and the extraction is performed. Providing a corner material to be attached to the notch of the wall plate of the box, providing a lid to be attached to the front opening, providing a lid plate to be attached to the back opening of the cover, and providing a supporting rod in the front opening. Storage container.

[0007]

To form the thin-walled groove portion in the middle position of the predetermined thickened material portions of the object, such as a container molding in [action] mold,
A protruding portion is provided at a predetermined portion of the mold to form a narrow portion, and the shear heat generated when the central portion of the synthetic resin material passes through the narrow portion is replasticized of the synthetic resin material after passing through. is the Umo rows molded integrally with the predetermined thickened material portion by using the.
(The principle diagram is shown in FIG. 8.)

As described above, if a narrow portion where the synthetic resin material is difficult to flow smoothly is formed in the mold, the resin material in the central portion of the flow during the injection molding of the synthetic resin material is formed in the narrow portion. However, it has been found that a heat generation phenomenon occurs due to friction between molecules at that time, and the shear heat generation of the synthetic resin material refers to such a phenomenon.
When molded by such a method, the synthetic resin material on the end portion to be cooled is replasticized by heating.

[0009] Therefore, the upper wall portion of the three side walls of the extracted box constituting the whole of the formed storage container is horizontally folded inwardly in a concave groove serving as a narrow portion thereof, and is further covered. The lower portions of the left and right side plates of the frame are horizontally folded in the narrow groove portion, and these members are extracted together with the corner material on the box side and the back cover on the side of the cover frame along with the cover. As shown in FIG. 7, the plate and the support rod are packaged together in a flat, horizontal state.

When assembling this storage container during use,
The upper wall portion of each wall plate of the extracted and boxed body is set upright, and the corner material is engaged so that both corners are erected and fixed, and a lid is fitted into the front opening.

On the other hand, when the lower portions of the left and right side plates of the cover frame are set upright, the back cover plate is engaged with the rear opening and the support frame rod is fitted into the front opening.

The extracted box is inserted into the cover frame in such a state. (See Fig. 2)

When a plurality of storage containers are stacked, the wheels below the side plate of the cover frame of the upper storage container are fitted to the concave steps of the corners of the cover frame plate of the lower storage container. This puts the wheels in a stopped state. (See Fig. 3)
