Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage case, and more particularly to a storage case composed of a drawer, a case body, and a top plate, each of which is integrally formed of a synthetic resin.

[0002]

2. Description of the Related Art Various types of storage cases have been proposed for storing, for example, clothing, video tapes or compact discs.
No. 40570 and the like. In addition, since this type of storage case can be provided in large quantities and at low cost, it is generally formed of a synthetic resin as a material.

Although the storage case made of synthetic resin can be finished to be uniform and beautiful, it is necessary to minimize the amount of synthetic resin used and to reduce the cost. In this case, since a portion having insufficient rigidity appears, it may be deformed when used for a long period of time, and for example, it may be impossible to access the drawer.

[0004] In particular, in the case body into which the drawer is drawn in and out, when the drawer is drawn out largely, a large force is applied to the vicinity of the draw-out opening as shown in FIG. Because each drawer contains video tape, etc., when it is pulled out, its center of gravity moves largely outward from the access opening of the case body, and the rear part of the drawer opens at the access opening of the case body. This is because they will be supported nearby.

In general, when the drawer is pulled out to take out the video tape contained therein, the user generally releases his / her hand from the drawer. At that time, the drawer is supported by the access opening of the case body. Although it must be done, the rigidity in this part is often insufficient, and it is quite possible that the part is deformed.

In such a case, it is only necessary to reinforce the vicinity of the access opening of the case body. However, when viewed from one case body, the reinforcement is provided on the upper side of the access opening, that is, on the top plate side. There are some difficulties in doing this.

[0007] The lower surface of the front end of the top plate must be flat so that the drawer can be smoothly inserted and removed. Of course, the lower surface of the front end of the top plate must be flat so that the drawer can be taken in and out even if the thing put in the drawer protrudes from the upper edge. For this reason, an extra thing for reinforcement cannot be attached to the front end lower surface of the top plate. On the other hand,
It must be clear so that it can be placed on top of it and another one placed on it.

The inventor of the present invention has conducted various studies on this kind of storage case as to how to ensure the rigidity of the vicinity of the access opening without difficulty, and as a result, completed the present invention. is there.

[0009]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned situation in this type of storage case, and the problem to be solved is to secure the necessary rigidity when the drawer is pulled out. is there.

That is, first, an object of the invention according to claim 1 is to provide a storage case which can increase the rigidity in the vicinity of the access opening of the case main body and which does not hinder the draw-in / out operation. It is to provide by a simple structure.

The object of the second aspect of the present invention is to achieve the same object as the first aspect of the present invention and to easily attach and detach a reinforcing bar for securing rigidity. It is an object of the present invention to provide a storage case that can reliably maintain a mounting state of a reinforcing bar.
