In the disc storage case 21, the glue margin portion 22d of the blank 22 having the shape shown in FIG. 19 is folded on the base portion 22a, and then the upper surface portion 22b is folded on the base portion 22a to be suitable for the glue margin portion 22d. Means, for example, glue to form a bag, and a thin non-woven fabric 26 is attached to the inner surface of the bag to form a pocket for storing the disk 25. The non-woven fabric 26 used here is for protecting the disc 25, and is preferably smooth and soft, and is preferably made of resin fiber such as polypropylene, polyester or polyethylene.

As shown in FIG. 18, the disc storage case 21 has a cover portion 2 after the disc 25 is stored in a pocket constituted by a base portion 22a and an upper surface portion 22b.
2c is folded on it using the crease line 23b, and in that state, or the whole is shrink-wrapped and distributed.

The disk storage case 21 of the above embodiment is
Since it has an extremely simple structure, it can be manufactured at low cost,
Moreover, since the non-woven fabric is arranged on the inner surface of the pocket for accommodating the disc 25, there is an advantage that the disc 25 is surely protected. Even if a part of plastic non-woven fabric is used, the amount of the non-woven fabric used is small and most of it is made of paper, so that it is easy to incinerate and there is no problem in disposal.
Further, similar to the above-described embodiment, the effect of easy printing can be obtained.

22 to 26 show still another embodiment. The disc storage case, generally designated by the reference numeral 31, is composed of two blanks 32 and 33 shown in FIG. The blank 32 is a crease line 34 such as a crease.
It has a base portion 32a divided by a and 34b, a folded portion 32b, and a cover portion 32c.
A cut 35 for inserting a tongue piece described later is formed in 2b. On the other hand, perforations 36a and 36b for tearing are formed on the cover portion 32c, and the region 37 between them can be torn and removed. Blank 3
3 is an upper surface portion 33a having an area substantially equal to that of the base portion 32a.
And has fold lines 3 on both sides of the upper surface portion 33a.
A glue margin portion 33b is provided in series via 8. A large recess 33c is formed in the upper surface 33a. The recess 33c is provided to facilitate the loading and unloading of the disc. On the back surface of the blank 33, the nonwoven fabric 40 is provided on both end portions (the area outside the broken line 39 in FIG. 23).
(See FIG. 22) is attached. The same paperboard as the blank 2 shown in FIG. 1 is also used for the blanks 32 and 33 used here, and as shown in FIG. 22, it is possible to exhibit desired rigidity when assembled in a box shape. Its thickness is defined.

Next, a method of assembling and using the disc storage case 31 will be described. After preparing the blanks 32 and 33 having the shape shown in FIG. 23, the glue margin portions 33b at both ends of the blank 33 are raised in a substantially U-shape, and the glue margin portions 33b are attached to the base portion 32a of the blank 32 to form a rectangular cross section. Then, the folded portion 32b is raised, and the upper surface portion 33
Stick on a. This state is the state shown in FIGS. 24 and 25, and a storage space for storing the disc 42 is formed between the base portion 32a and the upper surface portion 33a. After inserting the disc 42 into the storage space, the cover portion 32c is folded over the upper surface portion 33a by using the fold lines 34b, and as shown in FIG. The area 44 is attached below it. Thereby, the disc 42 is favorably accommodated and protected in the disc storage case 31. The disk storage case 31 is distributed in this state, or in a shrink-wrapped form if necessary.

Here, as can be seen from FIG. 25, since the upper and lower surfaces of both ends of the disk 42 accommodated inside are supported by the nonwoven fabric 40, the disk 42 is not damaged during transportation. Further, since there is a glue margin portion 33b under the non-woven fabric 40, there is a step with respect to the base portion 32a,
Therefore, the surface of the disc 42 does not directly contact the base portion 32a, and the protection of the disc 42 is further ensured.

The user who obtains the disk storage case 31 tears and removes the area 37 between the perforations 36a and 36b formed on the cover portion 32c for use. As a result, the cover portion 32c is separated from the upper surface portion 33a below the cover portion 32c.
And the disc 4 inside as shown in FIG.
2 can be taken out and used. Also at this time,
A tongue portion 32d is formed at the tip of the cover portion 32c. When the cover portion 32c is reclosed, the tongue portion 32d is inserted into the cut 35 to fix the cover portion 32c in the closed position.

Thus, the disc storage case 31
Also, since it is formed of the paper blanks 32 and 33, it can be manufactured at low cost, is easy to print, and can be incinerated. The disc storage case 31 has a box-shaped storage space for discs.
Moreover, since the both ends of the disc are supported by the non-woven fabric, the disc is surely protected and is not damaged during transportation or storage. Further, since the non-woven fabric is arranged only at both end portions that support the disc, the amount of the non-woven fabric used can be minimized and the cost can be reduced.

It is kept in a state where it does not come into contact with 82a and the cover portion 82b, and therefore is not damaged during transportation. In addition, the base portion 82a and the cover portion 82b
Since the disk storage member 83 made of paperboard is disposed between the case and, the compression resistance is large, and the case does not collapse even if it receives a compressive load. Further, the supporting member 89 is simply cylindrical and its outer diameter is set to be slightly larger than the center hole of the disc, so that the disc can be fitted into the center hole of the disc to fix the disc. It is easy and cheap to manufacture. In addition, since the disk storage case 81 of this embodiment is also mostly made of paper as in the other embodiments, it is possible to reduce costs, print easily, and incinerate easily. Have the effect of.

Although the disk storage cases having various structures have been shown above, the dimensions of these disk storage cases may be appropriately determined according to the diameter of the disk to be stored, but the conventional plastic case is used. It is also possible to make the external dimensions equivalent to. Adopting such external dimensions is convenient when it is stored side by side with a conventional plastic case.
