Description

[Detailed description of the invention] (a) Industrial application field This invention is a packaging for mounting and supporting a thin disc having a central hole such as a record board, magnetic disc, or optical disc (compact disc, laser disc, etc.). Regarding the body.

(b) Conventional Technology Conventionally, record boards and magnetic disks such as floppy disks have been inserted into paper bags.

On the other hand, the compact disk
As disclosed in Japanese Patent No. 155583, a compact disc is housed in a shallow resin case, and the case is covered with a resin shallow dish lid that is pivotally supported at one end of the case. Protected and stored.

(c) Problems to be solved by the invention In cases where the thin disk is simply stored in the paper bag, the thin disk cannot be fixedly held within the bag, and the thin disk protection is insufficient.

In the case where the compact disc is housed in the resin case and lid, the central hole of the compact disc is press-fitted into the central protrusion of the case, and since these cases and lids are hard, the compact disc cannot be stored easily. Although the protection is sufficient, the overall thickness is large and the need for simpler packaging cannot be satisfied.

The present invention has been devised in view of the above points, and it is possible to improve the protection of the thin disk compared to the paper bag, reduce the thickness compared to the case using the resin case, and make the packaging easier. The problem to be solved is to simplify it.

(d) Means for solving the problem The present invention is constructed by sequentially connecting first, second, and third sheet materials of approximately the same size, and bending the continuous portions of adjacent sheet materials. The first sheet material has a pair of chevron-shaped slits with their respective tops facing each other, and the pair of slits are arranged between the ends of the opposing slits. is formed so that one side is wide and the other is narrow, and by bending the approximately triangular piece partitioned by each chevron-shaped slit, it is formed between this approximately triangular piece and the slit. The insertion part of the thin disk to be stored is formed in the gap between the first sheet material and the bridge part, and the second sheet material is folded into the first sheet material. The third sheet material has a window hole that exposes a part of the thin disc to be supported, and the third sheet material is formed by folding the first and second sheet materials to form the first sheet material on the side not facing the second sheet material. It is characterized in that it can be stacked on the back of the material.

(e) Effect In the above configuration, by bending a pair of opposing substantially triangular pieces defined by each mountain-shaped slit of the first sheet material, the first sheet member formed between the substantially triangular piece and the pair of mountain-shaped slits is bent. An insertion portion is formed in the gap between the sheet and the bridge portion. Since one of the slit ends of a pair of opposing slits is wide and the other is narrow, the thin disk to be stored, which is inserted from the side between the ends of the wide slit, becomes the insertion part, and the end of the narrow slit is inserted. It is supported to prevent it from falling out. Further, due to the restoring force of each substantially triangular piece, the thin disk is frictionally supported between the substantially triangular piece and the bridge portion.

By folding the first sheet material stored and supported with the thin disk material at the continuous part with the second sheet material, and stacking it on the second sheet material, one part of the thin disk material can be inserted through the window hole of the second sheet material. part is exposed. Next, the second sheet material is folded at the continuous portion with the third sheet material, so as to overlap the third sheet material, and the third sheet is placed on the back surface of the first sheet material on the side that does not face the second sheet material. By positioning the material, the back side of the first sheet material is protected.

(f) Examples An embodiment of the present invention will be described based on the drawings.

FIG. 1 is a developed view of the package. As shown in this drawing, the package A is constructed by sequentially arranging rectangular first, second, and third sheet materials 1, 2, and 3 of approximately the same size in a row, and the adjacent sheet materials are The continuous parts 4 and 5 are folded lines, and the three sheet materials 1, 2,
3 is folded three times. Each sheet material has four sides larger than the diameter of the thin disk B (see FIG. 2) which is the storage support article. In the embodiment, the sheet material is cardboard, but it may also be constructed from a plastic sheet. Further, in the embodiment, the thin disk B is a compact disk.

The first sheet material 1 has a pair of mountain-shaped slits 6,
7 with their tops 8 and 9 facing each other. In the one shown in FIG. 1, a pair of slits 6,
7 face each other on the left and right, their respective top parts 8 and 9 are separated from each other, and a bridge part 10 is formed between the pair of slits. In this case, the width between the upper slit ends 11 and 12 of the pair of slits is larger than the diameter of the thin disc B, and the width between the lower slit ends 13 and 14 is the width of the thin disc B. It has become narrower with smaller dimensions.

The second sheet material 2 has a circular window hole 12 smaller than the thin disk B in the center.

By bending the substantially triangular pieces 16 and 17 defined by the slits 6 and 7 of the first sheet material 1, a gap is created between the substantially triangular pieces and the bridge portion 10, and the thin disc In this embodiment, when the thin disc B is inserted from above the insertion part 18, the width between the lower slit ends 13 and 14 becomes narrower than the diameter of the thin disc B. Therefore, thin disk B
are supported by the slit ends 13 and 14. Further, due to the restoring force of the substantially triangular pieces 16 and 17, the thin disk B is frictionally supported by the substantially triangular pieces 16 and 17 and the bridge portion 10.

The first sheet material 1 containing and holding the thin disk B in this manner is bent at the continuous portion 4 and stacked on the second sheet material 2, as shown in FIG. Then, the first sheet material 1
A part of the thin disk B held by the second sheet material 2
It is exposed through the window hole 12 (see Fig. 4).

Next, as shown in FIG. 3, the third sheet material 3 is stacked on the back surface of the first sheet material 1 on the side that is bent at the continuous portion 5 and does not face the second sheet material 2, and the third sheet material 3 is folded on the back surface side. Protect the exposed thin disk B. FIG. 4 shows a state in which three sheets 1, 2, and 3 are folded.
Note that the continuous portion 5 has a width in consideration of the thickness of the first sheet material 1 and the thin disk B.

FIG. 5 shows a perspective view of a package A in which a booklet 19 such as an instruction manual or an explanatory booklet is provided on the inner surface of the third sheet material 3.

In the above embodiment, the pair of mountain-shaped slits 6, 7 of the first sheet material are opposed to each other on the left and right,
In this example, the thin disk B is inserted from above. As shown in FIG. 6, a pair of mountain-shaped slits 6, 7 are arranged to face each other vertically, and the thin disk B is inserted from the connecting portion 4 side into the insertion portion 18 between the approximately triangular pieces 16, 17 and the bridge portion 10.
In the case of the one shown in Fig. 6, even if the thin disk B tries to slip out of the insertion portion 18 in the opposite direction to the insertion direction during folding of the three sheet materials 1, 2, and 3 for some reason, it can come into contact with the connecting portion 4 and be prevented from slipping out.

Further, in each embodiment, a case is shown in which three sheet materials are arranged in a row, but three sheet materials may be arranged in a row in an L-shape.

(g) Effects of the invention As described above, according to the invention, a pair of chevron-shaped slits are provided in the first sheet material so that their tops face each other, and the approximately triangular pieces defined by the chevron-shaped slits are bent. Accordingly, an insertion part for the thin disc to be stored is formed in the gap between this approximately triangular piece and the bridge part of the first sheet material formed between the slits, and the thin disc is inserted and held in this insertion part. is protected by the second sheet material and the third sheet material which are connected to the first sheet material, so the protection of the thin disc is enhanced compared to the conventional method of simply inserting it into a paper bag. In addition, the thickness can be made thinner than that using a conventional resin case, and packaging can be simplified.

In addition, since the opposing slit ends of the pair of chevron-shaped slits are formed so that one is wide and the other is narrow, the thin disk inserted from the wide insertion part is inserted into the narrow slit end. The thin disk can be housed and held by the restoring force of the substantially triangular piece in combination with the frictional holding between the substantially triangular piece and the bridge section.

Furthermore, since the second sheet material has a window hole that exposes a part of the thin disk that is housed and held by the first sheet material, it is possible to visually confirm that the thin disk is being stored.
