Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc storage case for storing a storage medium such as a CD (compact disc), an LCD (laser disc), an MCD (micro compact disc), an FD (floppy disc) and an optical disc. .

[0002]

2. Description of the Related Art Conventionally, there are various types of disk housing cases for housing disks. For example, as shown in FIG. 8 and FIG. 9, a disc storage case for a music CD has a synthetic resin holding insole 70 for holding the disc 50 so as not to move to the center thereof.
And a plastic outer box 72 for accommodating the insole 70 therein. Insole 70 for holding the disk 50 in its center against movement
Is a bottom portion 74 having a shape that substantially matches the outer peripheral shape of the disk 50 and is slightly larger than the outer peripheral shape, and two hill portions 76 that project above the bottom portion 74 and guide the outer circumference of the disk 50. , A substantially cylindrical elastic locking portion 78 projecting upward from the bottom portion at the center of the bottom portion. The elastic locking portion 78 has a tubular portion 80 having a taper whose diameter gradually decreases from the bottom portion 74 to the upper tip portion, and a disc portion 84 having a hole 82 in the center at the tip of the tubular portion 80, which are integrated with each other. It is a thing. The elastic lock 78 has a hole 82.
A plurality of radial slits 86 centering on the center and communicating with the hole 82 are formed over some areas of the disc portion 84, the tubular portion 80, and the bottom portion 74. The insole 70 is fitted into a plastic outer box 72 to form a conventional disk storage case. When the disc 50 is stored in the disc storage case, the hole 52 of the disc 50 is fitted into the elastic locking portion 78, and the inner edge of the hole 52 is fixed to the cylindrical portion 80.
Contact. As a result, the slit 86 of the elastic locking portion 78 is narrowed, and the disc 50 is held in a state of being fitted to the elastic locking portion 78 by the force of the opening direction of the slit 86.

[0003]

However, in the conventional plastic case, since the insole 70 and the outer box 72 are molded by the resin molding means, the manufacturing cost such as die cost is very high. Further, the current plastics generate harmful gas when burned at the time of disposal, and even if they are buried in the soil, they are not decomposed, and the treatment of plastic cases such as disk storage cases has been highlighted as a pollution problem. Further, it is conceivable to manufacture the disc storage case using paper or the like, but there are drawbacks that the opening / closing operation cannot be performed with one touch, or the lid opens immediately and dust enters.

The present invention has been made in order to solve the above-mentioned problems, and it is possible to provide a disk storage case which is not subject to pollution even if it is disposed of, is low in cost, can be opened / closed with a single operation, and dust does not enter. The purpose is to provide.

[0005]

DISCLOSURE OF THE INVENTION The present invention relates to a disk storage case made of a flexible material for storing a disk having a data recording section, and a base member including a bottom portion, a connecting portion and a cover plate, and the base member thereof. A middle plate having a hole large enough to allow the disc to pass through, and a hole large enough to allow the disc to finally pass through the plate attached to the outside of the middle plate. And a fitting plate that is attached to the lid plate of the base member and fits into the hole of the upper plate, insert the disc from the hole of the upper plate into the hole of the middle plate, and fit the lid part. The plywood is fitted into the hole of the upper plate and the hole of the upper plate is closed so that the disc is housed inside the upper plate, the middle plate, the bottom and the lid.

[0006]

According to the disk storage case of the present invention, the size is such that the disk can finally pass through the hole in the upper plate on the front side into which the disk is inserted, and the hole in the middle plate after passing through the upper plate is the hole in the upper plate. Make it bigger. This allows the disc to move freely within the hole in the middle plate, but prevents the disc from being removed through the top plate unless the disc matches the hole in the top plate. This allows the disc to be stored inside the upper plate without easily slipping out. Since paper is mainly used as a material for the disc storage case, it can be easily disposed of and the disc is not damaged. Further, since the lid is fitted in the hole of the upper plate, dust does not enter when the disc is stored.

[0007]

First Embodiment Next, the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view showing an embodiment of a disk storage case according to the present invention. This disc storage case
The base member 10 is mainly composed of a base member 10, a plate-shaped lower plate 12, an intermediate plate 14, and an upper plate 16, and the base member 10 includes three plate-shaped lower plates 1.
2 and the middle plate 14 and the upper plate 16 are superposed and bonded together. The thickness of the intermediate plate 14 is 14
Thicker than the thickness of. The material of the base member 10, the lower plate 12, the middle plate 14, and the upper plate 16 is most desirable because paper is inexpensive and easy to process, but if it is not subject to pollution problems due to treatment such as incineration or burial. , Other than paper may be used. For example, when a plastic that is not subject to pollution problems is developed by treatment such as incineration or burial, such plastic may be used.

The base member 10 is composed of three continuous regions of the bottom portion 18 and the connecting portion 20 and the cover plate 22. The bottom part 18 and the connecting part 20 can be bent, and the connecting part 2
It is also possible to fold between 0 and the cover plate 22. As shown in FIG. 2, the bottom portion 18 is composed of a back plate 24 connected to the connecting portion 20, a support plate 26 having a width substantially the same as that of the back plate 24, and a glue margin 28. 28 back plate 2
By adhering to No. 4, a gap 30 is formed between the back plate 24 and the support plate 26. In this gap 30, a required document is put in according to the purpose. For example, this storage case is C for music
In the case of D case, a lyric card or the like is inserted in this gap 30. An annular support guide 32 for supporting the central portion of the disc is adhered to the center of the support plate 26. The thickness of the annular support guide 32 is set to the lower plate 1
It is almost the same as the thickness of 2. The support guide 32 has an annular inner diameter larger than the inner diameter of the central hole 52 of the disk 50. That is, by making the support guide 32 annular and making the inner diameter of the annular larger than the inner diameter of the hole 52 of the disc 50, when the disc 50 is taken out from the storage case, a finger can be inserted into the hole 52 of the disc 50. , So that the disc 50 can be easily removed from the storage case.

As shown in FIG. 1, the lower plate 12, the middle plate 14 and the upper plate 16 which are superposed and attached to each other are provided with holes 34, 36 and 38 having similar shapes. These holes 3
4, 36 and 38 have large arc shapes with different diameters. Here, the diameter of the arc of the hole 34 of the lower plate 12 is D _1, and the diameter of the arc of the hole 36 of the middle plate 14 is D ₂ .
Assuming that the diameter of the arc of the hole 38 of the upper plate 16 is D ₃ and the diameter of the disk 50 to be housed is D ₀ (see FIG. 3), the relationship between these diameters D ₁ , D ₂ , D ₃ and the diameter D ₀ is D ₁ <D
Set ₀ , D ₂ > D ₀ , D ₃ > D ₀ . Also, the lower plate 1
In the state where the second plate 2, the middle plate 14, and the upper plate 16 are joined, the centers of the diameters D ₁ , D ₂ , and D ₃ are the same. Further, the diameter D ₃ of the hole 38 of the upper plate 16 is equal to the disc 50.
The diameter is larger than the diameter D ₀ , but the size is set to be very small (about 1 mm to 2 mm). Furthermore, the middle plate 1
The diameter D ₂ of the hole 36 of No. 4 is set larger than the diameter D ₃ of the hole 38 of the upper plate 16. In other words, the hole 38 in the upper plate 16
Is large enough for the disc 50 to pass through,
The hole 36 of the middle plate 14 is sized to allow the disc 50 to pass therethrough, and the hole 34 of the lower plate 12 is sized to prevent the disc 50 from passing therethrough.

The lower plate 12, the middle plate 14 and the upper plate 1 in FIG.
6 and the lower plate 12 are adhered to the support plate 26 of the base member 10 in this order, and the holes 38 of the upper plate 16 are formed.
When the disk 50 is horizontally inserted into the base member 10 from above, the disk 50 passes through the hole 38 of the upper plate 16 and the hole 36 of the middle plate 14, but does not pass through the hole 34 of the lower plate 12 (FIG. 3). Passes the disc 50 through the hole 38 of the upper plate 16,
Shown is the state in contact with the lower plate 12). As a result, as shown in FIGS. 3 and 4, the disk 50 inserted from the hole 38 of the upper plate 16 is supported by the lower plate 12 near the outer peripheral edge of the surface on the insertion side. Moreover, since the thickness of the lower plate 12 and the thickness of the support guide 32 are substantially the same, the central portion of the disk 50 is in contact with and supported by the support guide 32.

The thickness of the intermediate plate 14 is set thicker than that of the disk 50, and the diameter D ₂ of the arc of the hole 36 of the intermediate plate 14 is set larger than the diameter D _{0 of the} disk 50. As such, the disc 50, while supported by the lower plate 12, is free to move until the outer peripheral edge of the disc 50 contacts the inner edge of the hole 36 in the middle plate 14. FIG. 5 shows a state in which the disc 50 is moved from the state of FIG. 3 and the outer peripheral edge of the disc 50 is brought into contact with the inner edge of the hole 36 of the intermediate plate 14. In the state of FIG. 5, a part (two places) of the disc 50 is covered with the upper plate 16 when viewed from the upper plate 16 side. Therefore, in FIG.
Even if you try to remove the disc 50 from the above state, the upper plate 1
Due to the presence of 6, the disc 50 cannot be taken out, and the disc 50 can be reliably stored inside without coming off. In other words, the disk 50 is the hole 38 of the upper plate 16.
Since the diameter D ₃ of the disk 50 is only slightly larger than the diameter D ₀ of the disk 50, the disk 50 cannot be taken out unless the outer peripheral edge of the disk 50 fits inside the inner edge of the hole 38 of the upper plate 16. .

As shown in FIG. 1, the cover plate 2 of the base member 10
A fitting plate 40 having a shape to be fitted into the hole 38 of the upper plate 16 is fixed to the second plate 2. As shown in FIG. 4, when the lid plate 22 is closed as shown by the chain double-dashed line after the disc 50 is housed, the fitting plate 40 is just fitted into the hole 38 of the upper plate 16 and the lid plate 22 is easily opened. Absent. Thus, the hole 38 of the upper plate 16 and the cover plate 2
Since the second fitting plate 40 is just fitted, dust does not enter from this fitting portion, and dust does not adhere to the disc during storage. Moreover, when the cover plate 22 is closed, the connecting portion 20 is in a state of being substantially at a right angle to the back plate 24 as shown in FIG. Two
The force to return to the same plane as 4 works. That is, the connecting portion 2
For 0, a force returning in the arrow X direction in FIG. 6 acts around the contact point P with the back plate 24. The force in the arrow X direction acting on the connecting portion 20 causes the outer peripheral edge of the fitting plate 40 of the cover plate 22 and the hole 38 of the upper plate 16.
At the joint point Q with the inner edge of, the fitting plate 40 is pushed in the Y direction, and the contact resistance at the joint point Q increases, and as a result, the lid plate 22 does not open more easily. The upper plate 16 is provided with a notch 42 at a central position where it joins the free end of the cover plate 22. When opening the cover plate 22, if a finger or a nail is put in the notch 42 and the cover plate 22 is lifted, the cover plate 22 can be easily opened.

As shown in FIG. 5, the disc 50 is generally provided with a hole 52 in the center thereof, and outside the hole 52, there is an annular inner non-recording portion 54 (a region between the hole 52 and the alternate long and short dash line 56). ) Is provided, an annular data recording section 58 (a region between the one-dot chain line 56 and the one-dot chain line 60) is provided outside the non-recording section 54, and an annular outside non-recording is provided outside the data recording section 58. A portion 62 (between the one-dot chain line 60 and the outer peripheral edge) is provided. Depending on the type of the disc 50, it may be desirable that the data recording sections 58 exist on both sides and that the data recording section 58 should not come into contact with anything. Therefore, as shown in FIGS. 3 and 5, no matter which position the disc 50 moves in the state where the disc 50 is housed, the position where the lower plate 12 or the upper plate 16 comes into contact with the disc 50 is set to the position of the disc 50. The lower plate 12 so that only the outer non-recording portion 62 is provided
The shape and size of the hole 34 of the above and the hole 38 of the upper plate 16 are set. As described above, only the outer non-recording portion 62 of the disc 50 can be in contact with the disc 50 of the lower plate 12 or the upper plate 16 because the lower plate 12 supports the vicinity of the outer peripheral edge of the disc 50. Can be achieved by The center of the disc 50 contacts the annular support guide 32. However, as shown in FIGS. 3 and 5, the annular support guide 32 contacts only the inner non-recording portion 54 regardless of the position of the disc 50. To do so.

Here, there is a risk that the fitting plate 40 of the lid plate 22 on the upper surface of the disk 50 will come into direct contact with the data recording section 58 on the upper surface of the disk 50. In that case, as shown in FIG. In addition, the support guide 3 is attached to the fitting plate 40.
A holding plate 44 having the same shape as that of 2 is adhered. Then, the total thickness of the fitting plate 40 and the pressing plate 44 is made equal to the thickness of the upper plate 16. As a result, the disk 50 can be stored in the case without touching the data recording sections 58 on both sides. The data recording unit 58
Even if the upper plate 16 or the like comes into contact with the disk storage case, since the disk storage case mainly uses paper, the data recording section 58 is generally not damaged.

In the above embodiment, the lower plate 12 and the middle plate 14
The holes 34, 36, 38 of the upper plate 16 and the holes of the upper plate 16 are made substantially similar in shape. However, the hole 38 of the upper plate 16 has a size such that the disk 50 can pass through the hole 38 of the middle plate 14
As long as 6 has a size that allows the disc 50 to pass through with a sufficient margin, the respective holes of the lower plate 12 and the middle plate 14 may be set in any shape. Further, the disc storage case may be stored inside a cubic outer case having only one surface as an opening.

[0016]

Second Embodiment Next, another embodiment of the disk storage case according to the present invention is shown in FIGS. In these figures, the same symbols as in FIG. 1 indicate the same parts. Foundation member 46
Is a connecting portion 47 to the cover plate 22 of the base member 10 of the first embodiment.
And the cover plate 48 are sequentially attached integrally. A space between the cover plate 22 and the cover plate 48 can be bent via the connecting portion 47. A fitting plate 49 is attached to the lid plate 48. In the first embodiment, the lower plate 12, the middle plate 14, and the upper plate 16 are provided only on one surface of the bottom portion 18 of the base member 10.
However, in this embodiment, the lower plate 12, the middle plate 14, and the upper plate 16 are laminated and bonded to each other on both sides of the bottom portion 18 of the base member 46. On both sides, the side closer to the base member 46 is the lower plate 12, and the upper plate 16 with the middle plate 14 interposed is the side farther from the base member 46.

In this embodiment, as shown in FIG. 9, a total of two disks 50 can be accommodated, one on each side of the base member 46. Thereafter, the fitting plate 40 of the lid plate 22 is just fitted into the hole 38 of the upper plate 16 on one side, and the fitting plate 49 of the lid plate 48 is just fitted to the hole 38 of the upper plate 16 on the other side. Since the holes 22 and 48 are not easily opened and the hole 38 of the upper plate 16 is closed, dust does not enter through the hole 38 and dust does not adhere to the disc during storage. Thus, in the second embodiment, two disks 50 can be stored.

[0018]

As described above, the storage case is conventionally made of plastic, but according to the present invention, it is sufficient to perform punching processing on a flexible material such as paper and combine them, and to manufacture the storage case at an extremely low cost. be able to. Also,
The conventional plastic had a problem of pollution when it was discarded, but since the material used in the present invention can be burned, there is no problem of pollution at all. Furthermore, it is a storage case made of materials such as paper, which can be opened and closed with one touch,
Moreover, it is possible to completely prevent dust from entering.
