Description

  The present invention relates to a disc storage case suitable for storing various media discs (hereinafter simply referred to as “discs”) such as compact discs (CDs), MDs, and DVDs.

  For example, as a case for storing discs such as CDs, a plastic case in which upper and lower case bodies are connected so as to be openable and closable was attached to a paper board at first. When a plastic case is used, a case with a special shape or pattern is produced for the purpose of giving individuality to the shape or design. It was impossible to put it to practical use because there was a problem that it was not possible to make a profit because it was expensive.

  Therefore, in order to reduce the cost of the case, for example, as shown in Patent Document 1, a paper tray is also configured so that it can be freely inserted and removed from the inside of a paper case formed entirely in a box shape. In addition, as shown in Patent Document 2, a simple envelope-type paper or non-woven case in which a disk is inserted has been developed.

  However, the box-shaped paper case described in Patent Document 1 is composed of a total of four members: a paper case 1, a core plate portion 3, a disc holder 4, and a guide holder 5. In addition, there are many places that need to be bent at the time of manufacturing, adhesive margin for bonding, or printing surface, etc., and especially for the disk holder that holds the disk, in order to maintain a three-dimensional shape, Since it is necessary to paste each glue allowance, there is a problem that manufacturing and assembling take much time, time, and expense, and the manufacturing cost increases though it is made of paper.

  In addition, in the case of the envelope-type disk storage bag described in Patent Document 2, the manufacturing cost is low, but the disk may fall from the opening of the case, and the disk may be damaged. Because the paper case itself is not strong enough to protect the disc from external pressure, the disc is prone to breakage, and the recording surface of the disc is in direct contact with the surface of the paper case, thus protecting the recording surface safely. There were a number of problems such as being unable to do so.

  Therefore, the technical problem of the present invention is that a disk having a function that can be easily assembled, can reduce the manufacturing cost, can securely hold the disk, and can safely protect the recording surface. It is to provide a storage case.
