[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage case made of only a flexible paper material such as cardboard and for storing a disk-type recording medium such as a compact disk.

[0002]

2. Description of the Related Art Conventionally, as a storage case for an expensive and large magnetic recording medium such as a compact disk, a thin rigid plastic case having an openable and closable lid on one side thereof is mainly used. In some cases, paper bags are also used.

[0003]

Since this rigid plastic case is strong against external force, it is advantageous in that it can house a magnetic recording medium, and can be transported or stored. However, there is a problem that the manufacturing cost is high because the plastic case is formed by resin molding using a mold, and the shape is restricted by the use of the mold. Further, the amount of use of this plastic case has been increasing year by year, and accordingly, a large number of plastic cases that have become damaged or unnecessary have been generated. Moreover, when they are disposed of, they are generally incinerated,
In this case, high combustion heat and harmful gas are generated, and even if the waste is disposed of in landfills instead of incineration, it does not corrode and decompose for a long period of time, causing a problem on the global environment. Further, some paper bags are intended to simply store the magnetic recording medium in the paper bag, and thus have a problem that they are not suitable for protecting the stored magnetic recording medium in terms of strength. The present invention has been made to solve these problems. In other words, the present invention focuses on the characteristics that paper materials such as cardboard are easy to process and are easy to dispose of. An object of the present invention is to provide a disk-type recording medium storage case that can sufficiently protect a recording medium and can easily handle the storage disk-type recording medium.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned object, and has a storage portion for storing a disk-type recording medium, which is made of a paper material. The present invention relates to a disk-type recording medium storage case in which a pair of opposing side walls are formed in a bellows shape so that a disk-type recording medium can be housed in a pair of bellows-shaped valleys (edges). The storage case is formed of a paper material as a backing sheet, the center of which is a disk-type recording medium storage surface, and a pair of bellows-shaped disk-type recording medium support pieces provided at a portion facing the storage surface. Further, at least one of the pair of portions on the other surface of the storage surface is provided with a folded piece. Then, a pair of bellows facing the side wall of the disk recording medium storage portion are formed by bending the bellows-shaped disk type recording medium locking piece,
The folded piece is bent to form another side wall and a lid that covers the upper part of the disk-type recording medium storage part, thereby forming a disk-type recording medium storage case. The disc-type recording medium is sandwiched in a state of being floated on the valley surface (edge portion) of the bellows portion, and is stably engaged without providing a special stopper by the elasticity of the bellows portion. In addition, the bellows can sufficiently withstand external pressures from above and below, and from vertical and horizontal directions, so that the disk-type recording medium is not damaged. Examples of the disk-type recording medium include a compact disk, a laser disk, and an optical disk. However, especially compact discs (CD, CD
-I, CD-V, etc.) from the viewpoint of its properties. Examples of the paper material include paperboard, paper, cardboard, carton paper, and those obtained by laminating or printing thin paper printed thereon. There is no particular limitation on the number of bellows. At the bottom of the bellows, insert a leaflet explaining or advertising the contents recorded on the recording medium, and insert the leaflet into the valley (edge) of the next step. A disk-type recording medium is inserted, and held between the upper and lower sides and the left and right sides by the elasticity of the bellows while being stably floated. However, as shown in FIG. 2, it is desirable to form only one valley for accommodating only one disk, because the strength of the storage case is significantly increased and the disk is not damaged.

[0005]

According to the present invention, a support for a disk-type recording medium such as a compact disk is formed in a bellows shape by bending a paper material, and this is used as side walls on both sides of the disk-type recording medium storage portion. It can be formed only by bending the raw material, and the manufacturing process is simple. Further, since the storage disk type recording medium is sandwiched between the opposing valleys (edges) in the middle of the pair of bellows-like support pieces, it becomes a floating state.
The elasticity and cushioning properties of the bellows are effective in protecting the storage disk type recording medium. In particular, when used for storing a compact disc, it is preferable that the bare surface is not damaged during transportation or storage.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view of the disk-type recording medium storage case according to the present invention. The storage case (1) is a box-shaped case made of a flexible material such as cardboard, which stores a recording medium such as a compact disk so as to surround the storage medium from above and below and from the side. On both left and right sides of (2), a pair of bellows-like support pieces (3) and (4) are provided to sandwich and support the side surface of the stored item. Two lids (5) and (6) are provided. Moreover, it is formed only of a flexible paper material. This storage case can be formed by bending a single piece of flexible paper material shaped as shown in FIG. In other words, the center is a rectangular storage container receiving surface (2), and rectangular overhanging pieces (9) and (10) are formed from both left and right sides (7) and (8) of the storage surface to form bellows-like support pieces. Each of the overhanging pieces (9) and (10) has three folding lines (11) to (1).

Next, another embodiment of the present invention will be described. One of the lids may be adhered to the upper surface of a bellows-like support piece to form a box having an open end. Also,
A protruding piece may be provided on one lid, and a locking tool such as a notch or the like into which the protruding piece can be inserted may be provided on the other lid to lock both. Further, both lids may be bonded with an adhesive or the like without using such a locking tool. In the above embodiment, two lids are formed. However, one lid may be used, and if the length of the lid is set so as to cover the opposite side, the storage case can be sealed with one lid. Further, one bellows is provided on the inside with three folds at the three folds. However, if the number of folds is increased and the number of the middle valleys is increased, a plurality of disk type recording media can be stored in one storage case. In the above embodiment, the storage surface is rectangular, but any shape may be used as long as a pair of bellows-like support pieces can be formed. Since the storage case is made of paper material, the manufacturing process is simplified.However, depending on the shape, the lid and the bellows-like support piece are separated, and these are adhered to the mount that forms the storage object storage surface. It may be formed.
The lid, the apertures may be set only for facilitating the removal of the disk-type recording medium accommodated. Further, without providing a lid portion, the storage surface can be covered with another package or stored in a separate box having an open end.

[0008]

As described above, according to the present invention, a disk-type recording medium such as a compact disk is sandwiched and supported by a pair of bellows-like supporting pieces, so that the disk-type recording medium is supported in a floating state. Since the bellows also have a cushioning function, they are not damaged even when a force is applied from the upper or lower surface or the lateral surface, and are less likely to be broken, so that they are excellent in transportation and storage.
Since the bellows-like support piece also serves as the side wall of the case, the structure is simple and the strength is strong. Further, since the storage case of the present invention is made of paper, it is light and easy to print and process. Further, since various designs can be easily made, and furthermore, it can be incinerated when discarded due to breakage or the like, it is also useful as an ecological product. In particular, the features of the disk-type recording medium storage case of the present invention will be described below using a compact disk (CD) storage package made of paper as an example.

A structure in which only the edge, which is the edge of the CD (the thickness of the CD), touches and supports the package.
The "floating state" in which the back surface (data surface) of D does not contact the inside of the package is enabled. The bellows-shaped box or three-dimensional structure enhances the strength of the package, acts as a cushion against external loads, etc., and protects the CD inside the package from being "scratched" or "cracked" I made it. Because it is all made of paper, it has excellent design. Because it is all made of paper, it is lighter than before. Lighter weight can reduce labor in the store. Since it is entirely made of paper, transportation costs can be reduced. Since it is entirely made of paper, it is environmentally friendly and can be reused. Because of the structure that is easy to produce, it is easy to mechanize and low cost. Compared with the conventional plastic package, the overall image is gentle.
