DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat storage box of a flat shell such as a disk-shaped recording medium inner shell such as a magneto-optical disk or a floppy disk.

[0002]

2. Description of the Related Art Conventionally, as a flat shell storage box of this type, at least three sides of a flat shell stored and placed in a relatively large plastic case are temporarily supported by vertical ribs on the inner surface of the case. In addition to preventing the inner horizontal delusion, the vertical movement of the flat shell is prevented by pressing the upper surface of the shell when the lid is closed with a cushioning material such as a sponge interposed at the top to close the shell inside the case. Was.

[0003]

In the prior art described above, a cushioning material such as a sponge or urethane material is separately required in addition to the case. It was very uneconomical for 20-30% of the case fee.

In addition, it is necessary to arrange and manage cushioning materials, and furthermore, it is necessary to place cushioning materials on the flat shell placed in the case. Accidents due to forgetting to assemble materials are easy to occur, and various types of cushioning materials must be prepared according to the thickness of the flat shell and the number of sheets to be stored. There was a point.

According to the present invention, in order to eliminate the above-mentioned problems, a shell receiving rib corresponding to the thickness of a flat shell housed in a case is protruded from a shell receiving piece, so that a cushioning material is not used. The purpose is to prevent shell delusions.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide a plastic molded box in which a flat shell is placed flat and accommodated, and a vertical rib is provided near an opposing inner surface of a substantially hollow rectangular parallelepiped case. And upper and lower shell receiving ribs are respectively provided on the inner surfaces of the shell receiving pieces connected to the vertical ribs, and V
A locking piece for locking the lid, which engages with the inner surface locking portion of the case, protrudes from the hinge-facing side of the case lid extending through the cut hinge, and receives the downwardly directed peripheral edge formed on the case lid. This can be achieved by forming a guide slope for slightly bending the front side inward when the lid is closed, on the upper part of the vertical rib where the side opposite the hinge approaches.

[0007]

The flat shells are sandwiched one by one from the lower ribs on the upper and lower shell receiving ribs against the resilience of the shell receiving pieces between the shell receiving pieces in the open case. It can be temporarily fixed by supporting it. Next, the case lid is put on the case via the hinge, and the locking piece of the case lid is engaged and locked with the locking portion of the case by the elasticity of the material, so that the closed state of the lid can be kept locked.

The shell receiving piece which has been supported by the flat shell with the closure can be slightly bent inwardly together with the shell receiving piece by the downwardly directed peripheral edge of the case lid which slides down the guide slope of the vertical rib. The flat shells, which are temporarily fixed, can now be tightly supported between the shell receiving pieces, and these shells can be permanently fixed to the case.

Next, in order to remove the flat shell in the fully fixed state from the inside of the case, first lift the front edge of the case lid by a finger, remove the locking piece from the locking portion of the case against its elasticity, and open it. By closing the shell, the shell receiving piece can be returned to the outside elastically, and the fixed flat shell can be unlocked and temporarily fixed, and the flat shell can be temporarily fixed. It can be taken out against the elasticity of the receiving piece.
