DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk-shaped record carrier package for accommodating a disk-shaped record carrier such as a compact disk, a CD-ROM, and a DVD.

[0002]

2. Description of the Related Art Conventionally, as a tool for accommodating a disk-shaped record carrier, there are a plastic protective case, a bag formed of nonwoven fabric, and a bag-shaped container formed of paperboard having a nonwoven fabric or film adhered to an inner surface thereof. .

[0003]

A plastic protective case, which is a conventional storage device for a disk-shaped record carrier, includes:
There are drawbacks in that the manufacturing cost is high, and when a large number of disk-shaped record carriers are stored due to the bulkiness, a corresponding space is required.

[0004] In addition, the method of storing in a bag formed of a nonwoven fabric has a disadvantage that the stored disk-shaped record carrier has weak protection. That is, the disc-shaped record carrier is only protected by the nonwoven fabric, and therefore, when pressure is applied from the outside, the pressure directly reaches the stored disc-shaped record carrier, and the disc-shaped record carrier is easily formed. May be damaged or broken.

[0005] In contrast to the above storage device, a bag-shaped container made of paperboard having a nonwoven fabric or a film adhered to the inner surface thereof is:
The manufacturing cost is not as high as that of a plastic protective case, and since it is made of paperboard, the protection of the disc-shaped record carrier housed therein is higher than that of a nonwoven bag. However, we bond nonwoven fabric and film to paperboard,
In addition, a two-step process of forming a bag is required, which requires some complexity of the process.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a disk-shaped record carrier package which is low in manufacturing cost, has high protection of a disk-shaped record carrier housed therein, and can be manufactured by a simple process. And

[0007]

In order to solve the above-mentioned problems, according to the present invention, a cardboard or paperboard package is provided.
A fold is provided while maintaining a distance substantially equal to the diameter of the disc-shaped record carrier, and a lid portion for covering the disc-shaped record carrier is formed on both sides of the fold, and when the package is folded, the folds oppose the inner surface of the package. Then, a means for protecting the recording surface of the disc-shaped record carrier by sandwiching the disc-shaped record carrier with the protruded strip is adopted. Hereinafter, what action the solution has will be described.

Since the disk-shaped record carrier package according to the present invention is made of cardboard or paperboard,
Manufacturing costs can be kept low.

Further, since the disk-shaped carrier is made of cardboard or paperboard, the stored disk-shaped carrier has high protection.
Furthermore, the fact that a ridge is inevitably formed against the inner surface of the package is simple because if a fold is formed on thick paper by the usual creasing method of an automatic flat plate punching machine, the fold is formed as a ridge. This is a necessary step in the process of making a package.

As described above, the package for a disk-shaped record carrier according to the present invention is made of cardboard or paperboard, so that the manufacturing cost is low, the protection of the disk-shaped record carrier housed therein is high, and furthermore, Creases in the cardboard, a process that is inevitable in the process of manufacturing the package, creates ridges to hold the disk-shaped record carrier, so special adhesives such as bonding a nonwoven fabric or film to the inner surface of paperboard This eliminates the need for processing steps and parts.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing a state of use of the present invention, FIG. 2 is a developed view of the present invention, FIG. 3 is a front view of the present invention, FIG. 4 is a rear view thereof, and FIG. FIG. 6 is a diagram showing a state in which the cardboard is creased.

The package according to the present invention is preferably made of cardboard or paperboard, and has a bag-like form as shown in FIG. FIG. 2 is an exploded view, in which the glue (1) is bent and the central ridge (3) is bent so that the glues (1) are stuck together to form a bag.

The ridges (3) are manufactured by a creasing method of an automatic flat plate punching machine. FIG. 5 is a view showing a state in which the cardboard is creased by the automatic flat plate punching machine. As shown in FIG. 5, when the cardboard is creased by the automatic plate punching machine, the crease (5) is obtained. Becomes convex, and it becomes possible to manufacture the convex stripe (3).

The position where the ridge (3) is manufactured is on both sides of the package (4) according to the present invention, that is, FIG.
In other words, it is the fold at the center and the fold at the bottom of the lid (2).

FIG. 5 is a sectional view taken along the line A--A of the present invention. The ridges (3) are provided on both sides, and the disk-shaped record carrier is held between the ridges (3).

FIG. 3 is a front view of the present invention, and FIG. 4 is a rear view of the same. As shown, the appearance of the package (4) according to the present invention is similar to a normal envelope.

Further, as another embodiment of the present invention,
There are those as shown in FIGS.

FIG. 7 is a front view of another embodiment of the present invention, and FIG.

Another embodiment of the present invention shown in FIGS. 7 and 8 is to fold a cardboard or a paperboard into three and store a disk-shaped record carrier, which has a simpler structure. As shown in FIG. 8, the disk-shaped record carrier (6) is sandwiched by the ridges (3) formed on both sides in a three-folded state.

In the package for a disc-shaped record carrier according to the present invention, the distance between the ridges (3) on both sides is slightly shorter than the diameter of the disc-shaped record carrier to be stored. Must be set to This is for effectively holding the disc-shaped record carrier. For example, CD or CD
-ROMs are 12 cm in diameter, so these CDs
In a package for storing a CD-ROM or a CD-ROM, the distance between the ridges (3) may be set slightly shorter than 12 cm.

[0022]

According to the present invention, since the present invention is constructed as described above, the manufacturing cost is low and the disk-shaped recording carrier can be reliably held by the ridges. It is possible to provide a disk-shaped record carrier package which has high protection and can be manufactured by a simple process.
