Description

  The present invention relates to a paper disk storage case for storing a disk-shaped storage medium such as a CD or a DVD.

Conventionally, as a storage case for storing or transporting a disk-shaped storage medium (hereinafter referred to as a disk) such as a CD or a DVD, a thin box-shaped storage case made by plastic molding has been widely used.
This is a thin box-shaped storage case that has a disc-shaped disk holding portion that is placed on the center of the disk and that fits in the center hole of the disk, and a cover that covers the disk to close the storage case.
With regard to this plastic molding, it can be constructed with light weight and strength, and it is suitable for mass production, and since it can be manufactured at a certain low cost, there are currently many types of plastic molding storage cases used. It is what.

On the other hand, since it is based on plastic molding, it is manufactured uniformly, and it has a structure that is ubiquitous in appearance, resulting in a low cost.
Furthermore, it was not suitable for incineration at the time of disposal, and was desired for some environmental solution.
In addition, because of plastic molding, when a force is applied to a specific portion such as a hinge portion, the portion is easily damaged, and the case itself is often broken at other locations.
This is because plastic molding has a certain level of strength, but if it exceeds that, it is prone to breakage, especially when it is pressed with a force-related part or protruding part, etc. It was.

Therefore, some countermeasure against this has been required.
Furthermore, when surface printing or the like is performed by plastic molding, many costs are high.
In view of the above points, paper storage cases are used instead of plastic molding.
First, Japanese Patent Laid-Open No. 2003-192077 (Patent Document 1) exists.
This has a tray on a substrate sheet, and both are formed of paper.
JP 2002-68354 (Patent Document 2) also clearly discloses a paper storage case provided with an R slit.

Furthermore, Japanese Patent Application Laid-Open No. 2001-122374 (Patent Document 3) clearly discloses a storage case having a storage portion into which a large number of sheets made of one paper sheet can be inserted.
In addition, there is JP-A-2002-370726 (Patent Document 4) in which a disk placed in an inner case is accommodated in an outer case that is divided into an outer case and an inner case.
Japanese Patent Laid-Open No. 2000-62764 (Patent Document 5) also exists as a storage case having a space having a bellows portion by a single paper sheet.
These are all configured with the advantage of being paper, and each has a feature in its shape.

An example of a storage case for storing a disk-shaped storage medium such as a CD or a DVD according to the present invention is shown in FIG.
The configuration shown in this figure is an example of a storage case in which a single paper sheet 1 is folded and bonded, and a disc-shaped disc holding portion 2 is mounted.
Therefore, the frame body portion 10 is overlapped and bonded to the bottom surface portion 11, the disk holding portion 6 is provided at the center portion of the bottom surface portion 11, and the lid body portion 12 is connected to the bottom surface portion 11. And can be closed by folding the lid 12.
In this state, the disk D is mounted on the disk holding portion 6 in this figure, and the lid body 12 has a slit 15 formed by a cut portion to hold necessary messages, materials, and the like.

The storage case is made of paper, can be configured by simple folding and bonding, and can easily perform various types of printing on the front cover, back cover, or both inner surfaces.
In the present invention, the paper sheet is not limited to a sheet made of only paper, but may of course be a resin sheet laminated or a multilayer sheet.
Next, FIG. 2 is a developed view of the paper sheet of the storage case.
As shown in the figure, a sheet 1 having a length and width slightly longer than about three times the length and width of the storage case at the time of molding is used as a basis.
The sheet includes a frame body portion 10 constituting a frame body, a bottom surface portion 11 constituting a bottom surface, and a lid body portion 12 constituting a lid body.
Further, the frame body portion 10 includes a frame body base surface 100 and both frame body portion overlapping surfaces 101 and 102 connected to both end portions thereof, and the both frame body portion overlapping surfaces 101 and 102 are provided on the frame body base surface 100. Each of the connecting lines 31 and 32 connected to each other is folded and overlapped.
The bottom surface portion 11 constituting the bottom surface also includes a bottom surface portion base surface 110 and both bottom surface portion overlapping surfaces 111 and 112 connected to both end portions thereof.

The both bottom surface overlapping surfaces 111 and 112 are folded at the connecting connecting lines 41 and 42, overlapped with the bottom surface base surface 110, and bonded with an adhesive member or the like. 11 is configured.
Further, the lid body portion 12 constituting the lid body includes a lid body portion base surface 120 and both lid body portion overlapping surfaces 121 and 122 connected to both ends thereof.
The lid part overlapping surfaces 121 and 122 are folded at the connecting connecting lines 51 and 52 respectively and overlapped with the lid part base surface 120, and are similarly adhered by an adhesive member or the like. The lid body portion 12 is configured by overlapping.

However, between the lid overlapping surfaces 121 and 122, it is necessary to have a surface that is not adhered between the two, and a non-adhered surface is provided with a slit made of a cut portion 15 between them. It will be pinched.
Further, the frame body base surface 100, the bottom surface base surface 110, and the lid body base surface 120 are connected to each other and can be bent therebetween.
In particular, between the frame body base surface 100 and the bottom surface base surface 110, the base surface portion and the overlapping surface portions each have a three-layer structure. In order to achieve this, the widths 21 and 22 are about the thickness of both two layers sandwiched between them, that is, a total of four layers.

Similarly, between the bottom surface base surface 110 and the lid body base surface 120, the folded frame body portion can be folded by folding the base surface portion and the overlapping surface portions, respectively. When the thickness of 10 is taken into consideration, the widths 23 and 24 are about the thickness of a total of seven layers.
By having such a width, it is possible to manufacture a case that has a high quality appearance.
The side surfaces located on both sides of the frame body base surface 100, the bottom surface base surface 110, and the lid body base surface 120 have the overlapping surfaces as described above. Are separated from each other and have approximately the same size as each base surface.
Therefore, when the overlapping surface is overlapped with the base surface, the edge portions are exactly the same.

Next, the frame body base surface 100 and the frame body overlapping surfaces 101 and 102 have notches 140, 141, and 142 that allow a disc to enter and a fingertip, respectively.
This is because the disk D is accommodated in the frame body portion, and a space is formed so that the outer periphery portion of the disk D can be taken out while being touched with a finger.
The configuration shown in this figure shows a diamond-shaped cutout with corners formed in rounded shapes, but this figure is only an example, and it may of course be constructed with other cutout shapes.
Next, the bottom surface overlapping surfaces 111 and 112 of the bottom surface portion 11 have holes 131 and 132 for mounting disk-shaped disk holding portions.

In this case, when the bottom surface overlapping surfaces 111 and 112 are folded and overlapped with the bottom surface base surface 110, a disk-shaped disk holding part 6 is sandwiched between them, and the disk holding part 6 protrudes from the holes 131 and 132. It is a hole for.
Therefore, the holes 131 and 132 are preferably located at the center, but may be provided at appropriate positions according to the disk arrangement position.
Furthermore, this configuration has holes 131 and 132 on both bottom surface overlapping surfaces 111 and 112, the hole 132 on one surface is slightly larger, and the hole 131 on the other surface is slightly smaller than this and is a disk-shaped disc. It consists of the size of the disk-shaped part 61 of the holding part 6.

This is such that the base portion 60 of the disk holding portion 6 is included in the slightly larger hole 132, and the protruding disk-like portion 61 is accommodated in the slightly smaller hole 131.
Accordingly, the disk holding portion 6 is mounted on the bottom surface base 110, and the bottom surface overlapping surface 112 having a slightly larger hole 132 is first folded and overlapped, and the bottom surface overlapping surface 111 having a slightly smaller hole 131 is further folded and overlapped. Thus, the bottom surface portion 11 can be configured. With this configuration, the thickness of the base portion 60 of the disk holding portion 6 can be adjusted by the bottom surface overlapping surface 111, and further, the disk holding portion 6 can be tightly aligned by overlapping. Can be installed.

Next, with respect to the lid body portion 12, one lid body overlapping surface 121 has a slit made of a cut portion 15, and both lid body portion overlapping surfaces 121 and 122 are folded into the lid body base surface 120. By making the surface having the cut portion 15 the uppermost surface when overlapping, an object can be inserted from the cut portion 15, and the object can be sandwiched and stored between the lid overlapping surfaces 121 and 122. It becomes.
Therefore, as described above, it is only necessary that the vicinity of the slit is bonded with an adhesive member or the like at least in the vicinity of the outer peripheral edge portion without bonding the cover body overlapping surfaces 121 and 122 to each other.
As described above, the sheet material shown in FIG. 2 can be easily manufactured by first performing necessary cuts and cuts on one paper sheet material.
Furthermore, folding such as superposition can be facilitated by making a crease at the same time or separately at the folding part.
That is, folding can be easily performed in the next process by making a crease at a necessary connecting line portion.

FIG. 3 is a diagram showing a state in which the respective overlapping surfaces are overlapped and overlapped.
This figure is a view inserted for easy understanding of the shape during folding, and is not a shape that needs to be temporarily used in the manufacturing process.
That is, as described above, both the frame body overlapping surfaces 101 and 102 are folded to form the frame body portion 10, and the bottom surface portion overlapping surfaces 111 and 112 are folded via the constant widths 21 and 22. In addition, it is connected to a lid body portion 12 formed by folding both lid body portion overlapping surfaces 121 and 122 through constant widths 23 and 24.
In the figure, these are respectively bonded by an adhesive member, but in the figure, since the disk-shaped disk holding portion is not yet arranged, they are adhered in a state where they are arranged.

FIG. 4 is a diagram showing a state in which a disk-shaped disc holding portion is arranged. As shown in the figure, the disc holding portion 6 is arranged and the respective overlapping surfaces 111 and 112 are bonded to each other to form a frame. The portion 10, the bottom surface portion 11, and the lid portion 12 can be formed, and each of them can also be folded and overlapped.
Regarding the process shown in this figure, after the process of cutting out the necessary sheet material shown in FIG. 2, a process of applying a necessary adhesive member and further folding and bonding each overlapping surface is performed. Any disk may be used as long as the disk holding part is placed and bonded or welded as necessary.

Next, the figure shown in FIG. 5 is a figure which shows the state which overlap | superposed the frame body part 10 on the bottom face part 11 further from the state of FIG.
By configuring in this way, the frame body portion 10 can hold a width greater than the thickness of the position where the disk D is to be stored, and the disk D can be stored safely.
Further, the disk D can be attached and detached as necessary.
Accordingly, by closing the lid in this state, the disk D can be effectively protected against external impacts.

In particular, the bottom surface portion 11, the lid portion 12, and the frame portion 10 are made of paper capable of cushion-like protection with respect to impact, and further each has a three-layer structure, which can be protected extremely effectively. Become.
As described above, the storage case according to the present invention can be easily manufactured by paper, and further has a three-layer structure as a protective material and is extremely resistant to impact.
In addition, because of the three-layer structure, each part has a thickness, which can give a sense of quality, and various decorations can be easily applied not only on the front and back surfaces but also on the inner surface by printing. A case can be provided.

In the present invention, a paper sheet is used, but as described above, in addition to thick paper, hard paper, etc., for example, a paper having a certain thickness, a composite sheet with another resin sheet, a laminate, or a coating It may be a sheet or the like.
Any sheet that uses a paper material at least in part may be used.
Next, in the present invention, in the description, it is described as being configured by bonding with an adhesive member at the stage of overlapping or folding of each part, but other than using an adhesive member, for example, using a composite sheet, It may be configured to have a welded object such as sonic welding.

The upper frame body portion 10, the bottom surface portion 11, and the lid body portion 12 are described on the premise that they have the same size, but they are not necessarily all the same size. For example, the bottom surface portion The frame body portion may be configured to be slightly small.
Further, the lid 12 may be larger than the bottom 11 for the convenience of opening and closing.
Therefore, each size may be determined arbitrarily.
Furthermore, it is optimal that the size of each overlapping surface is almost the same as that of the base surface, but it is not constrained by this, and the size of the overlapping surface is changed to give an accent. What is necessary is just to be able to improve cushioning property at least by folding.
