Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention accommodates a disc-shaped information recording medium such as an optical recording or magneto-optical recording medium,
Regarding a container for storage. The present invention relates to a container in which a disc product such as a CD or a CD-ROM can be attached to a book or the like, has excellent protection and sealing properties, is easy to take out the disc, and is easy to discriminate the contents.

[0002]

2. Description of the Related Art In recent years, a large capacity information recording medium utilizing light has been put into practical use. Among these media, there are products that are built into a cartridge and products that are used as a single medium such as a record. CDs and CD-ROMs are the latter products, but due to their widespread use, they are increasingly attached to books and sold for sale. Conventionally, these products are stored in a case made of plastic or paper by locking the center hole of the disc to the boss in the center of the case,
Enclosed items such as lyrics cards were enclosed in a predetermined place, and were wrapped in an overwrapping film to be handled. However, due to the opening and closing mechanism and the appearance of the container,
Compared to the disc body, it has a large size both in terms of plane and thickness, and is unsuitable for sticking to a book or the like. Furthermore, when removing the disc from the case, it is necessary to hold down the boss at the center to weaken the locking lock and grasp the outer edge of the disc with fingers to remove it, which not only results in poor workability. There were also problems such as the curvature of the disc. Further, such a container has a high cost.

As a simple type storage container, Japanese Patent Laid-Open No. 7-27
No. 7384 and Japanese Patent Publication No. 7-2511 are disclosed.

JP-A-7-277384 discloses a bag-shaped storage container. The opening is locked by inserting a small locking piece behind the disk to prevent the disk from coming off (FIG. 12). In this form, since the opening is not tightly sealed, the structure does not sufficiently prevent the invasion of dust and dirt from the outside. Further, in order to take out the disc, either the container is turned upside down and the disc is shaken out, or the front and back of the disc are grasped with fingers and taken out. Especially when it is attached to books, etc.,
There is a problem that it is difficult to swing out the disk, and if it is sandwiched with a finger, a fingerprint is attached to the optical surface on which the information is recorded, which may cause an error in reading the information. Further, the container is provided with an enclosure pocket on the outer periphery of the opening, and in order to reduce the overall size, it is necessary to make the enclosure pocket small. In some cases, the amount of information obtained when looking at the container from the outside was not small.

Japanese Patent Publication No. 7-2511 shows a container in which a front sheet forming a pocket for holding a disk is joined along three sides of a back sheet (FIG. 13). When the disc is taken out, since it is sealed on three sides, it can only be taken out in the direction with the flaps, and it is difficult to take out the disc, especially when the back surface is stuck to a book or the like. It has a structure. In addition, the enclosure has a structure that is inserted between the pocket containing the disc and the back sheet whose outer extension is a flap. Is difficult to take out, and particularly when attached to a book or the like, it becomes very difficult to take out. Also, since the front sheet and flaps perform the dustproof function, it is not necessary to connect the front sheet over the entire length of each side, but in order to make the dustproof function more effective, the front sheet is the side edge of the backsheet. -It is desirable that they are connected over the entire length of the bottom side. When the front sheet is joined to the container over the entire length of each side of the back sheet in order to improve the hermeticity, the pocket for holding the disc becomes deep, and it becomes more difficult to take out the disc.

[0006]

DISCLOSURE OF THE INVENTION The present invention is lightweight and thin, and has excellent disc protection and sealing properties, and particularly when attached to a book or the like, it is easy to take out the disc or enclosure. An object of the present invention is to provide a disc storage container having a function of visually recognizing a wealth of information regarding contents.

[0007]

In a disk storage container comprising a back sheet, a front sheet, and a flap, the back sheet is a composite sheet of a base material and a non-woven fabric, and at least the peripheral portion of the non-woven fabric is the above-mentioned substrate. Fixed to one side of the material, the front sheet consists of two sheets, one of which is joined along one side and the bottom of the back sheet to form a disc holding pocket, and the other one of the back sheet. Combined along the remaining sides, the flaps are combined along the top edge of the backsheet and overlap almost over the backsheet to form a lid for the disc storage container, which is lightweight, thin, and In addition, it is possible to obtain a disc storage container which has excellent disc protection and sealing properties and is particularly easy to take out a disc even when attached to a book or the like. Further, by connecting the transparent sheet to the flap and forming the enclosure for holding the enclosure, the enclosure can be easily taken out and various kinds of information about the disc can be easily visually recognized from the outside.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention relates to a disk storage container including a back sheet, a front sheet, and a flap.

The back sheet is a composite sheet of a base material and a non-woven fabric, and at least the peripheral portion of the non-woven fabric is fixed to one surface of the base material. The non-woven fabric faces the optical surface on which information of the disc is recorded when the disc is stored, and protects the optical surface. According to the present invention, the material, thickness, hardness, etc. of the back sheet base material do not become a factor that impedes the removability of the disc or the inclusion, and there is no particular limitation. For example, it is possible to use a rigid material such as a plastic plate or a metal plate instead of a sheet. Further, the side, bottom and corresponding side of the front sheet forming the disc holding pocket, which are connected to each other, do not need to be formed in a straight line according to the need of design or the like.

The front sheet is composed of two sheets, one of which is joined along one side and the bottom of the back sheet so as to be supported at at least two points on the outer circumference of the disk corresponding to the central angle of 90 degrees of the disk. To form disc-holding pockets and the other one is joined along the remaining side of the backsheet. By forming the disc-holding pocket by connecting the two sides, the angle at which the disc can be taken out from the disc-holding pocket becomes much wider than in the conventional bag-shaped container that is joined by the three sides. It's very easy to take out. The remaining one front sheet functions to prevent the disc from rolling out of the disc holding pocket and to prevent intrusion of dust and dirt from the outside when the disc is stored. Although the front sheet and the flap perform a dustproof function and it is not necessary to join the front sheet along the entire length of each side, in order to make the dustproof function more effective, each front sheet should be attached to the side of the back sheet. It is desirable that they are connected along the entire length of the side and the bottom. In the disc storage container of the present invention, even if the front sheet is joined over the entire length of each side, the disc take-out property is not hindered thereby, and both excellent dustproofness and disc take-out property are achieved. Is possible. Further, the edge of the front sheet corresponding to the opening of the disc holding pocket does not have to be a straight line, and the periphery of the disc and the central hole of the disc can be grasped by fingers when the disc is taken out. It is desirable to have a shape that covers the disc to the extent that a finger can fit in the center hole. The front sheet is made of a thermoplastic resin sheet or paper. Further, like the back sheet, by using a composite sheet with a non-woven fabric, the optical surface of the disk can be protected even when the user mistakenly stores the disk in the opposite direction. The front sheet may be bonded to the back sheet by a method such as heat-welding, ultrasonic welding, or gluing with a hot-melt resin or a pressure-sensitive adhesive to the above-prepared front-sheet material. Alternatively, the composite sheet may be extended and formed.

The flaps are joined along the upper side of the back sheet and overlap almost the entire surface of the back sheet to form a lid for the disc storage container and prevent the disc from rolling in the upper side direction. The flap can be formed in the same manner as the front sheet. The flap is made of a thermoplastic resin sheet or paper.

Further, in the disc storage container of the present invention, various information regarding the contents of the disc can be displayed on the flap. According to the present invention, it is possible to display a wide area, and it is possible to easily recognize various kinds of information. Various kinds of information about the contents of the disc include images such as portraits and designs of singers, and information about the contents of the disc such as lyrics and commentary. The display combines a transparent sheet on the outer surface of the flap,
A pocket for holding inclusions is provided, and a method for displaying various information on the outer surface of the flap by printing etc., or a pocket for holding inclusions on the inner surface of the flap in addition to printing There is a method of providing. Further, when the flap is made of a see-through material, a pocket for holding an enclosure may be provided on the inner surface of the flap.

When the front sheet or flap is formed by the extension method, if a crease is formed in the bent portion by a method such as scoring, the closed state of the front sheet or flap stabilizes and holds the disc. And dust resistance can be improved.

The non-woven fabric used is not particularly limited, but a thermal bonding type or chemical bonding type non-woven fabric with less defibering from the non-woven fabric is desirable. In particular, the chemical bonding type non-woven fabric is suitable because it has almost no defibering.

As the thermoplastic resin sheet, one having flexibility such as vinyl chloride, polyester, polyethylene or polypropylene can be used, and the thickness is 10
0 to 200 μm is desirable.

The disc storage container of the present invention can be used in the following forms. In other words, it is used independently, and the back sheets are attached together to form a disc.
It can be used as a container that can store multiple sheets, can be used by sticking it on a book, etc., or can be used for filing multiple sheets with a hole for stocking a holder etc. Protection of the
It is excellent in hermeticity, and even when it is attached to a book or the like, it is possible to easily take out the disc or the enclosure, and it is possible to sufficiently discriminate various information regarding the disc even when viewed from the outside.

As a form of sticking to a book or the like, there is a method of gluing the whole or a part of the back sheet, or a method of providing a portion serving as a glue margin on one side of the back sheet and gluing at that portion. . When the disc storage container is attached by the latter method, the attached pages of the book can be used in a foldable state.
