  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic plan view of Embodiment 1 according to the present invention, which can accommodate four compact discs. In FIG. 1, the sheet-like main body 11 uses a transparent plastic sheet having a high daylighting property having a haze value of 5 or less. As this plastic sheet, a polypropylene resin, a polyethylene resin, a polyester resin, a vinyl chloride resin, an acrylic resin, a polycarbonate resin, a nylon resin, or a polystyrene resin that makes printing clearer is used.

  Moreover, the transparent plastic sheet used as the sheet-like main body 11 needs to satisfy both two use conditions of use for wall hanging and use as a self-supporting case. In the first embodiment, the sheet-like main body 11 has a relation between the tensile modulus A (MPa) and the minimum thickness t (mm) satisfying the formula (1) of A × t = 40, Even if it is made thin for wall mounting, the strength as a self-supporting case is sufficient.

  In Example 1, the necessary condition was determined so as to satisfy the formula (1) of A × t = 40. That is, the sheet thickness of the disk constituting the sheet-like main body 11 is determined from the physical properties of the material to be used, so that both the use for wall hanging and the use as a self-supporting case are adopted.

  For example, when the sheet-like main body 11 is OPP (oriented polypropylene), if the tensile elastic modulus is 20 MPa, the one having a minimum thickness of 0.2 mm is used. Under this condition, the expression (1) of 20 MPa × 0.2 mm = 40 is satisfied.

  Further, when the sheet-like main body 11 has a PET (polyester) tensile elastic modulus of 43 MPa, the appropriate minimum thickness t1 is 43 MPa × t1 mm = 40 from the relational expression 43 MPa × t1 mm = 40, that is, the minimum thickness t1 = 0.93 mm. The thickness may be about 1 mm.

  Moreover, you may print a pattern on the sheet-like main body 11 with an ultraviolet curable ink as needed. Thereafter, a single punching process was performed to form a plurality of slits in the sheet-like main body 11 as shown in FIG.

The compact disc storage sheet 100 is formed with the folding portions 12, so that each folding portion 12 is divided into individual compact disc storage portions 13 and divided into substantially the same square shape, and a plurality of compact disc storage portions 13 are formed. However, it is formed in a strip shape in a row continuously.

  In Example 1, since the necessary condition was determined so that the plastic sheet of the sheet-like main body 11 satisfies the formula (1) of A × t = 40, the folding characteristic by the ruled line pressing at the time of the punching process is The sheet shape is excellent in maintaining flatness when it is placed on a flat surface or hanging on a wall, and when folded, it retains its folded shape (shape holdability). The main body 11 can be used as a self-supporting case.

  Further, a hole 14 for wall hanging is formed in the center of the upper side of the storage portion 13 of the uppermost compact disc of the compact disc storage sheet 100 by punching. A pair of U-shaped slits 15 and 15 are formed in the central portion of the storage portion 13 of each compact disc so as to be separated from each other toward the opposite sides. The tongue pieces 15 a and 15 a formed by the pair of U-shaped slits 15 and 15 function as locking pieces in the center hole 21 of the compact disc D.

  In the punching process, in addition to the U-shaped slits 15 in the storage portions 13 of the respective compact discs, a pair of arc-shaped slits 17 for inserting and supporting the corner portions of the jacket 16 for storing the compact discs D are supported. , 17 are formed at positions that are diagonally opposed to each other at a predetermined distance from the pair of U-shaped slits 15, 15. The tongue pieces 17a and 17a formed by the pair of arcuate slits 17 are formed to face each other at an angle of approximately 45 degrees of the jacket 16, and in the state of being accommodated in the arcuate slits 17 and 17, The pieces 17 a and 17 a function as locking pieces at each corner of the jacket 16. For example, when the respective corners of the jacket 16 placed on the surface of the sheet-like main body 11 are inserted into the slit 17 and stored on the back surface of the sheet-like main body 11, the tongue pieces 17 a and 17 a are formed on the surface of the sheet-like main body 11. In the vicinity of the slit 17 on which the jacket 16 is placed, the surface of the sheet-like main body 11 in the vicinity of the slit 17 is supported by supporting the jacket 16 from below with the surface in the vicinity of the slit 17 and pressing the tongue piece 17a from above. And the tongue piece 17a sandwich and hold the jacket 16 up and down.
