DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotating disk recording medium storage case for electronically recording information, such as a compact disk rotating body made of a composite of paper and plastic.

[0002]

2. Description of the Related Art A case for storing a recording medium such as a CD made of a composite of paper and plastic is composed of a relatively flat tray-like case body and a lid body for covering an opening of the tray body. In order to reduce the consumption of plastic materials and to simplify the collection and disposal of materials, they have been developed by using paperboard as far as possible, and cases of various structures have been marketed and developed.

A conventional flat CD case made of a composite of paper and plastic uses a plastic molded body for the frame, but uses paperboard for all the materials constituting the outer wall of the case. Was weaker in compressive stress and impact in the thickness direction applied to the outer wall surface of the case than in the case where all were manufactured by plastic molding.

For this reason, the structural paper constituting the wall surface of the case comes into pressure contact with the recording surface of the stored CD main body, and C
There were problems such as damage to the D surface and relatively low protection performance as a case for CDs.
