An intermediate plate 14 having a lateral dimension smaller than that of the top plate 15 and a vertical dimension substantially equal to that of the top plate 15 is formed, and a ring-shaped projection 13 for pressing a peripheral portion of a circular hole of the disc is formed on the intermediate plate 14. Have been. The protrusion 13 may or may not fit with the holding projection 9 provided on the disk storage portion A of the case body 2.

Further, in a state in which the front cover 3 is folded over the case main body 2 via the hinge portion 5 and the storage case 1 is closed, the edges of the case main body 2 and the front cover 3 are closed. A "U-shaped" end wall substantially surrounding the entirety of the portion, and two opposite end walls of said "U-shaped" end wall
17 is provided on the upper and lower ends of the front cover portion 3, and another end wall 16 is provided on the other end of the disk storage portion A of the case body 2.

In this way, a flat substantially rectangular parallelepiped space 18 is formed, one of which is surrounded by the top plate 15, the intermediate plate 14, and the two end walls 17, and is recorded on a disk stored in the space 18. A leaflet or the like on which the title, the content, or the photograph of the product is printed is set.

A fitting recess 12 for locking the case body 2 and the front cover 3 is formed at a position opposite to the other side end outside the upper and lower side surfaces of the disk storage portion A. A fitting projection 19 that fits into the fitting recess 12 is formed inside two opposing end walls of the front cover 3. The fitting concave portion 12 and the fitting convex portion 19 are necessary when closing the storage case 1, and perform a function of closing the storage case 1 in a pair. The concave portion 12 and the fitting convex portion 19 may be provided at any position of the storage case 1.

FIG. 2 shows an embodiment of the present invention in which the position of a hinge portion interposed between the case body 2 and the front cover 3 of the disk storage case 1 is changed.

Reference numeral 20 denotes an example showing a state in which the product is adhered by insert molding, whereby a label printed with the title, contents, or photograph of a product recorded on a disc to be stored is conventionally used as a back cover of a storage case. It is possible to abolish the setting work provided between the unit and the disk storage unit.

The thermal adhesive layer provided on the printed label 20 needs to be appropriately selected according to the thermoplastic resin used in the molding of the present invention, and is compatible with the thermoplastic resin. As long as it is a resin, it can be formed by a known coating method, or can be formed by laminating a film of the above compatible resin by a known technique by a known technique. Of course, when a film of the same resin as the thermoplastic resin used for molding is used for the label 20, it goes without saying that the thermal adhesive layer is unnecessary.

Although the embodiment in which the printed label 20 is adhered by insert molding has been described, the label 20 may be a transfer foil for painting only a printed pattern simultaneously with molding.

FIG. 4 is a cross-sectional view taken along the line YY of FIG. 1, and a printed label 20 having a heat bonding layer is adhered to the outer surface of the bottom surface of the case body 2 by insert molding. It is an example showing a state.

FIG. 5 is a cross-sectional view of the front cover 3 shown in FIG.
Reference numeral 21 denotes a ring-shaped receiving base 8 provided at the center of the circular recess 7 for accommodating the disk of the case main body 2, the peripheral edge of the circular hole of the disk being supported, and provided inside the receiving base 8. A state in which a ring-shaped projection 13 of the front cover 3 is fitted into the ring-shaped holding projection 9 for holding a circular hole of the disc and is held by the holding projection 9, and This is an example showing a state in which a leaflet or the like on which a title, contents, a photograph, or the like of a product recorded on a disk to be stored is set in a space 18 provided in the lid portion 3.
