DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved compact disk storage bag used when attaching a compact disk to a book.

[0002]

2. Description of the Related Art A compact disk has been widely used as a record carrier for various kinds of information because of its small storage size in addition to its large storage capacity. As the price of the compact disc has become lower, the compact disc has often been attached to the appendix of books such as books and magazines. In this case, there is a tendency to avoid the price increase of the book due to the attachment of the compact disc as much as possible, and there is also a demand that the case of the compact disc does not make the book thick. For this reason, as containers for compact discs attached to books and magazines, instead of hard plastic box-shaped cases called jewel boxes and widely available in the market, paper bags etc. with open tops are used. in use.

[0003]

However, in such a paper bag, the compact disc may fall out of a book during transportation or at a store, or the optical surface (the surface on which information is recorded) of the compact disc may be damaged. Accidents such as the adhesion of dust such as paper powder are likely to occur. Another drawback is that the compact disc can be easily taken out of the bag and easily taken out of the book and stolen.

The present invention solves the above-mentioned drawbacks, prevents accidents such as falling out of a compact disc, scratching an optical surface, and adhering dust, and also stores a compact disc that cannot be easily removed. The purpose is to provide bags.

[0005]

According to the present invention, in order to achieve the above object, according to the present invention, a back sheet is formed by bonding a tack paper to a back of a non-woven fabric with a synthetic resin film interposed therebetween and forming a part of the back sheet. Open the compact disc slot. Then, a transparent front sheet provided with a weakening line longer than the outer diameter of the compact disc to be accommodated is overlaid on the nonwoven fabric side of the back sheet, and the peripheral edges of the front sheet and the back sheet are heat-welded. Tack paper is obtained by applying an adhesive to one surface of a release paper. After the adhesive is applied to a nonwoven fabric or the like, the adhesive is exposed when the release paper is peeled off, and the nonwoven fabric can be bonded to another.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a front sheet, which is a transparent rectangular sheet made of soft polyvinyl chloride. Here, “transparent” includes translucent as well as generally referred to as transparent.
A semicircular weakening line 3 slightly larger than the outer diameter of the compact disc 2 to be accommodated is provided on the upper part of the front sheet 1.
(See FIG. 1).

Reference numeral 4 denotes a back sheet.
A nonwoven fabric 5, a synthetic resin film 6, and a tack paper 7 having the same dimensions as those described above, and the tack paper 7, the synthetic resin film 6, and the nonwoven fabric 5 are sequentially stacked and bonded (FIG. 2).
reference). The tack paper 7 is obtained by applying an adhesive 9 on a release paper 8. After the adhesive surface coated with the adhesive 9 is attached to the synthetic resin film 6, the release paper 8 is peeled off. The adhesive 9 moves to the 6 side. The synthetic resin film 6 and the nonwoven fabric 5 are laminated by lamination. Further, a compact disc insertion port 10 longer than the diameter of the compact disc 2 to be accommodated and shorter than the lateral width of the back sheet 4 is formed in the upper portion of the back sheet 4.

[0008] Then, the front sheet 1 is overlaid on the nonwoven fabric 5 side of the back sheet 4, and the periphery thereof is heat-welded (weld processing).
The compact disk storage bag 11 is formed (see FIG. 1). At the time of this thermal welding, the synthetic resin film 6 prevents the adhesive 9 from oozing to the nonwoven fabric 5 side and causing poor adhesion. The synthetic resin film 6 must be made of a material that is resistant to heat and does not exude the adhesive, and is preferably a nylon film or the like. The transparent front sheet 1 is preferably resilient so that the label surface of the compact disk is not transferred or damaged, and a soft polyvinyl chloride sheet or the like is used.

The compact disk storage bag 11 is used as follows. First, the recording surface of the compact disc 2 is put into the bag with the recording surface of the compact disc 2 facing the nonwoven fabric 5 side from the slot 10 (see FIG. 4), and the release paper 8 is peeled off and attached to the book 12 (see FIG. 3). The purchaser of the book separates the weakening line 3 and takes out the compact disc 2 from the front sheet 1 (see FIG. 5).

The compact disk slot 10 is provided with a bag 11
Is affixed to the book 12 to prevent the compact disk 2 from falling off during transportation or when displayed at a store. In addition, compact disk storage bag 1
No dust enters in 1.

[0011]

According to the present invention, since the compact disc insertion opening is opened in a part of the back sheet, the compact disc can be easily stored in the bag from here. Further, since the tack sheet is used for the back sheet, the storage bag can be easily attached to the book simply by peeling off the release paper. In addition, the compact disc slot is closed by simply sticking it to a magazine, etc., without any work such as bending the bag mouth, preventing dust from entering from here and causing the compact disc to fall out of the bag. Can be prevented. In addition, since the back sheet was formed by adhering the tack paper with a synthetic resin film sandwiched between the back of the nonwoven fabric, the adhesive oozed out to the nonwoven fabric side when the front sheet and the back sheet were heat welded, resulting in poor adhesion. And the front and back sheets can be securely bonded. Further, since the weakening line longer than the outer diameter of the compact disk to be accommodated is provided at the upper part of the front sheet, the compact disk cannot be taken out unless the weakening line is cut off. Therefore, the shoplifting of the compact disk can be prevented. After purchase,
Although it is necessary to cut off the line of weakness, the compact disc can be taken out by relatively simple operation without tools. The non-woven fabric protects the recording surface of the compact disc from scratches.
