Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a disk-shaped recording medium storage case, and more specifically, to a disk storage case suitable for storing compact disks.

[Conventional example]

Since optical information recording disks, such as compact disks, are played back using optical pickup, they must be handled with care to avoid dust or finger marks from getting on the recording surface.

For this reason, a special case is provided for this type of disk, and the disk is stored in the case when not in use.

[Problem that the invention attempts to solve]

However, most conventional cases are made of synthetic resin and require expensive molding molds, resulting in high manufacturing costs. Furthermore, since it is difficult to directly print on the surface of synthetic resin, a printed matter displaying the contents is placed inside the case. Furthermore, since this type of case has a flat box body, it also has the operational disadvantage that it is difficult to hold the case body when opening the case cover.

This idea was devised in view of the conventional circumstances mentioned above, and its purpose was to make it possible to use relatively inexpensive and easy-to-print paper as a material, and to make it possible to take out and store disks with simple operations. An object of the present invention is to provide a disk-shaped recording medium storage case.

[Means for solving problems]

In order to achieve the above purpose, the storage case of this invention consists of a case body that is a flat rectangular box with one side open, and a case body that is folded in half to sandwich a disk, which appears inside the case body together with the disk. a drawer member that can be stored;
A locking tongue folded inward is provided at the opening of the case body, and a bendable wing plate is connected to one side plate of the drawer member through a fold line, and the wing plate is A folded flange that can be engaged with the locking tongue is formed at the end.

[Effect]

In the above configuration, the disk is held in the case body together with the drawer member while being held between the drawer members. When the drawer member is pulled out from the case body, the folding flange of the wing plate engages with the locking tongue, so that the wing plate is bent so as to open outward from the case body from the fold line. As a result, a portion of the disk is exposed, and the disk can be removed from the case body.

〔Example〕

Hereinafter, one embodiment of this invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is an external perspective view of this disk-shaped recording medium storage case when the disks are stored, and FIG. 2 is an exploded perspective view of the storage case. Further, FIG. 3 is a sectional view taken along the - line in FIG. 1.

This storage case includes a case body 10 and a drawer member 20 built into the case body 10 so as to be retractable.

The case body 10 is made of a rectangular flat box, and an opening 11 is provided on one side of the case body 10. A locking tongue piece 12 that is folded back toward the inside of the box body is connected to one longitudinal side of the opening 11 . Furthermore, V-shaped cut grooves 13, 13 are formed approximately at the center of both longitudinal sides of the opening 11 to allow the drawer member 20 to be gripped. The case main body 10 has a pair of front walls 14 and a rear wall 15, which are punched out from a piece of cardboard in an unfolded state, bent into a box shape, and then cut into, for example, the front wall. It is assembled by gluing the flaps 16, 16 formed on both sides of the flap 14 to the rear wall 15 of the other party.

The drawer member 20 is formed in a bifold shape.
It has a pair of side plates 21 and 22. In this case, one side plate 21 has a first fold line 2 in the shape of a mountain fold.
The wing plate 24 is bendably connected to the blade plate 24 through the blade 3, and a stopper 33 for preventing the blade from coming off that engages with the locking tongue piece 12 is cut and raised. The wing plate 24 is provided with a second fold line 25 in the form of a mountain fold for folding its end side downward, and
A flange 26, which cooperates with the locking tongue piece 12 and forms a stopper, is folded back at the end thereof.
According to this embodiment, the skirt portion 24a of the wing plate 24
A third crease line 27 is formed in the shape of a valley fold to make the hem portion 24a parallel to the side plate 21. Further, a notch hole 28 is formed in the ridgeline portion formed by the first crease line 23 and expands from that portion toward both the side plate 21 and the wing plate 24 . On the other hand, above the other side plate 22,
As shown in FIG.
A cover piece 29 is provided at the bend to cover the edge of the disk D located inside the disk. Note that there is a crease line 30 that allows this cover piece 29 to be folded.
A fold line 31 is provided at a lower position to allow the cover piece 29 to escape to the side so as not to get in the way when the disk D is inserted or removed. Like the case body 10, this drawer member 20 is also made from, for example, a piece of cardboard.

In the above-described configuration, the disk D is held between the side plates 21 and 22 of the drawer member 20 and is housed together with the side plates 21 and 22 in the case body 10 (see FIG. 3). In order to take out the disk from inside the case body 10, cut grooves 13 and 1 in the case body 10 are required.
When you pinch the upper edge of the drawer member 20 at the part 3 and pull it out, the folded flange 2
6 engages with the locking tongue piece 12, and the hem 24 of the wing plate 24
a is captured in the opening 11. Therefore, when it is pulled out further, the first fold line 23 and the second fold line 25 become a mountain fold, and the third fold line 27 becomes a valley fold, so that the wing plate 24 becomes as shown in FIG. When viewed from the side, it opens into an inverted triangular shape, thereby exposing a portion of the disk D. Therefore,
The user folds the cover piece 29 along the crease line 31 and releases it to the side to remove the disc D.
The disk D can be taken out without touching the recording surface by placing one's fingers on the peripheral edge and the center hole H of the disk.

On the other hand, in order to store the disk D, with the drawer member 20 pulled out from the case body 10 as shown in FIG.
0 between the side plates 21 and 22, cover with the cover piece 29, and then push the drawer member 20 into the case body 10. During this pushing operation, the wing plate 24 is housed in the case body 10 in a state where it is stacked parallel to the other side plate 22.

In this embodiment, the storage case is made of cardboard, but a thin plastic plate may be used instead.

〔effect〕

As is clear from the description of the embodiments described above, according to this invention, it can be made by punching a plate material such as cardboard into a predetermined shape and bending it, so it can be manufactured without using a conventional molding die. It can be provided at a comparatively low price. In addition, if it is made of paper, it is also advantageous in this respect because it is possible to directly print the song list, singer name, etc. using normal printing means. Furthermore, since the disk can be pulled out from within the case body, the effect is remarkable, such as better operability than the conventional case cover opening/closing type.
