The optical disk 5 can be stored in the optical disk storage case 10.

The pedestal portion 20A of the exterior portion 20 has
As shown in FIG. 1, claw portions 26 </ b> C, 26 </ b> C for preventing the disk from falling off are formed on two side surfaces connected to the connecting portion 29. As shown in FIG. 3, when the outer part 20 is closed when the optical disk 5 is stored (the lid part 20B is overlapped with the pedestal part 20A), the disk drop-off preventing claws 26C, 26C are pressed into the lid part 20C as shown in FIG. The lid 20C slightly attempts to return to the direction of pushing up the lid 20C (the direction indicated by the black arrow in the figure) against the force (indicated by the white arrow in the figure). As a result, in the state where the exterior part 20 is closed (the state where the lid part 20B is pressed against the pedestal part 20A side by the action of the stopper band 28B), the claw parts 26C and 26C are in close contact with the inner surface of the lid part 20C. .

At this time, the claws 26C, 26C are
In the optical disk storage case 10 made of paper 0, the following operational effects are exhibited. That is, the exterior part 20
Is made of paper, when stored, the paper lid 20B is soft and easy to bend, and even if the exterior part 20 is closed and the lid 20B is stopped on the pedestal part 20A side by the stopper band 28B (see FIG. 3). , A white arrow), and a gap is formed between the pedestal portion 20 and the pedestal portion 20.

Is provided, the claw portions 26C and 26C can be attached to the lid portion 20B even if the lid portion 20B flexes in a state where the exterior portion 20 is closed.
Since it is in close contact with B, the adhesion as a case is ensured. That is, even when the optical disk 5 comes off the boss 32 during transportation or the like, the claw portions 26C, 26C come into close contact with the lid portion 20B, so that the optical disk 5 falls out of the gap formed between the lid portion 20B and the pedestal portion 20A. There is no. As described above, by providing the claw portions 26C, 26C on the pedestal portion 20A, even when the exterior portion 20 is made of paper, a sufficient holding property of the optical disk 5 can be ensured as in the case of the plastic storage case.

The length of the claw portions 26C, 26C in the longitudinal direction is formed to be about one third of the length of the side surface of the pedestal portion 20A. When the outer part 20 is closed, it does not become a hindrance when it is fitted into the base 31, and the adhesion between the pedestal part 20A and the lid part 20B can be sufficiently ensured. Next, a disk holder 30 made of non-woven fabric (made of polyester) applied to the optical disk storage case 10 of this embodiment and a method of attaching the disk holder 30 to the pedestal portion 20A will be described with reference to FIGS. I do.

As shown in FIG. 4, the disk holder 30 is formed of a nonwoven fabric into a hollow papier shape. In the center of the disk holder 30, a circular disk storage recess 31 and a boss 32 are formed.

As described in detail above, in the optical disk storage case 10 of the present embodiment, the disk holder 30 made of non-woven fabric is made of a material (for example,
Since the exterior 20 to which the disc holder 30 is attached is made of paper, the optical disc storage case 10 that is environmentally and environmentally friendly can be provided as a whole. In addition, since the disk holder 30 is made of polyester, it can be recycled, and resources can be effectively used.

Further, the optical disk storage case 1 of the present embodiment
A value of 0 makes the disk holder 30 made of a nonwoven fabric elastic, thereby improving its cushioning property.
Also, the exterior part 2 to which the disc holder 30 is attached
0 is also formed of elastic cardboard 200,
The excellent cushioning properties of the disc holder 30 and the exterior part 20 combine to provide high cushioning properties for the optical disc storage case 10 as a whole, which is optimal for storing the optical disc 5.

Further, since the exterior part 20 is formed of a paper material, the lid part 20B is particularly liable to bend.
Is closed (the lid 20B is superimposed on the pedestal 20A), the claw 26 formed on the pedestal 20B is closed.
Since C and 26C are pressed against the lid 20B side, the holding property as a case is excellent, and even when the stored optical disk 5 comes off the boss 32, the optical disk 5 does not fall out of the optical disk storage case 10. Therefore, the optical disk 5 is suitable for transportation.

FIGS. 11 and 12 are a development view and a perspective view, respectively, showing a pedestal portion 40A and a lid portion 40B according to a modification of the optical disk storage case 10 of the present invention. The exterior part 40 of this modified example is different from the exterior part 20 shown in FIG. 10 in that a notch is not formed in the front mount (second mount) 45. By not forming the notch in this way, the shape of the cardboard 400 is simplified (FIG. 11). In the figure, 40
A is a pedestal, 40B is a lid, 45 is a backing paper, 46 is a backing paper, 46C and 46C are claw parts, 47 is a front cover paper, 48 is a backing paper, and 49 is a connecting part.

In this embodiment and the modified example, the disk holder 30 is made of a non-woven fabric made of polyester. However, other fiber materials (other chemical fibers, natural fibers, etc.) are used. Even if a disk holder is made of a nonwoven fabric, the same effect as that obtained when polyester is used can be obtained. Further, instead of the disk holder 30 of the present embodiment and the modified example, a disk holder made of a paper material may be manufactured. In this case, as the paper material, Japanese paper-laminated paper or the like can be considered. When the disc holder is made of a paper material in this way, the entire optical disc storage case 10 can be made of a paper material, so that no harmful gas is generated during incineration. Also, by using paper, an optical disk storage case that is friendly to the earth and the environment can be obtained.

Further, even when the disk holder is made of paper, sufficient elasticity can be provided, so that its cushioning property is improved, and the cushioning property of the paper outer part 20 is combined with the optical disk. High cushioning properties can be obtained as a whole storage case. In the present embodiment and the modified example, the length of the claw portions 26C, 26C, 46C, 46C in the longitudinal direction is set to be about one third of the length of the pedestals 20A, 40A. As long as the optical disk housed between the pedestals 20A and 40A is strong enough not to fall off, the optical disk may of course be shorter than this. In addition, as long as it does not hinder the storage of the optical disk, it goes without saying that the length may be longer.

Further, in the present embodiment and the modified example, the example using thick paper as the paper material has been described. However, if the paper material has elasticity and can be folded, it can be pasted with cardboard or Japanese paper. Other paper materials such as paper can be used.

In the present embodiment and the modification, the lid 20
B also shows an example in which the front cover paper 47 and the back cover paper 48 are formed in two layers to provide strength, but the cover 20B may have a single structure. In the present embodiment and the modification, the lid 20B
Is described on the base 20A side by inserting the stopper band 28B into the cut 26E, but the lid 20B may be stopped on the base 20A side by other means such as a Velcro.
