Paper CD case {PAPER COMPACT DISC CASE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper CD case. In particular, when a compact disc (hereinafter referred to as "CD") is taken out / stored, the recording surface of the CD can be protected from being damaged by scratches, etc., and it is made of paper material to facilitate recycling. And it also relates to a paper CD case that can be designed in a variety of colors and forms.

CD cases that house CDs individually are usually made of plastic. The so-called plastic CD case includes a base having an open top, a support frame formed so that a CD is placed on an upper surface thereof and detachably embedded in the base, and a cover rotatably coupled to one end of the base.

According to such a plastic CD case, the hinge portion connecting the base and the cover can be easily broken, and if the CD case is accidentally dropped on the floor or a big impact is applied to the CD case, it is easily broken due to the characteristics of the plastic material. There is this. In addition, the plastic CD case is inserted between the base and the base, the paper advertisement is usually printed product information, etc., because it is cumbersome to remove the paper advertisement is a cause of making it difficult to recycle. In addition, in order to make the plastic CD case into various shapes, many expensive molds are required to meet the shape, thereby increasing the manufacturing cost. Therefore, the plastic CD case has to be manufactured in a simple and uniform shape, thus failing to satisfy various tastes of consumers. . In addition, plastics have many environmental hazards due to their characteristics. Moreover, the plastic CD case has a problem that the user feels uncomfortable because the touch is hard and cold.

On the other hand, in order to solve the problems of the plastic CD case, a paper CD case made of a paper material has been proposed.

Most of the conventional paper CD case is made of a simple and thin pocket form by a thin paper material has the advantage that can be supplied at low cost. However, in order to insert or withdraw a CD in a conventional paper CD case, the CD must be pushed in or pulled out. In the process, the recording surface of the CD is scratched and damaged by friction with the paper CD case, thereby preventing expensive software from using the recorded CD. Things happen frequently. In addition, when a CD is stored in a conventional paper CD case, when the paper CD case is shaken, the CD recording surface and the paper CD case are rubbed by the flow of the CD, which may cause scratches on the CD recording surface. Furthermore, since the conventional paper CD case is thinly formed, if a large impact is applied to the surface, or if the paper CD case is put on a different surface with a different height from the paper CD case, the CD bends or breaks easily. Almost no function

In order to replace the plastic CD case while considering the problems of the conventional paper CD case, the paper CD case of Korean Utility Model Registration No. 248910 has been proposed by the present applicant.

The paper CD case includes an outer case of a paper material having an inner space of which one side is opened, an inner case formed of a paper material so that the CD is placed, and retractably inserted into the inner space of the outer case, It includes a separation prevention means for limiting the withdrawal of the inner case so that the inserted inner case is separated out of the outer case.

According to the paper CD case, it is possible to solve all the problems of the conventional plastic and paper CD case, but since the CD support portion constituting the inner case and the recording surface of the CD placed thereon are in surface contact, When the CD is stored / detached, scratches may occur due to friction on the recording surface of the CD.

The present invention was made to solve the problem of the paper CD case of the Korean Utility Model Registration No. 248910 proposed by the present applicant to replace the plastic paper CD case, and the recording surface of the CD when scratching the CD is removed. It is an object of the present invention to provide a paper CD case which can be protected from damage.
