A tray member 46 for fitting and holding the CD 45 is disposed inside the case body 42. The tray member 46 is generally formed of a white or colored hard synthetic resin material. .
[0004]
A booklet-shaped lyrics card 47 is held by a holding projection 48 inside the lid 44, and a back jacket (not shown) is sandwiched between the tray member 46 and the case body 42. . On the lyrics card 47, the lyrics of the recorded songs and the like are printed, and on the back jacket, titles, recorded song names, artist photos, various illustrations, artistic designs, and the like are drawn.
[0005]
A display piece 49 (generally referred to as a “band”) as shown in FIG. 9B is directed to the side 41 a of the CD case 41, and in this state, the entire cellophane for packaging ( (Not shown), and is displayed and sold after being perfectly wrapped. The display piece 49 is formed of a vertically long piece of paper bent in a U-shape, and on the surface thereof, a title, an artist name, a recorded music name, a fixed price, a bar code, and the like are displayed.
[0006]
Further, as a CD storage case capable of storing lyrics cards, commentary books, etc., for example, (2) a structure (jacket for a compact disc) disclosed in Japanese Patent Application Laid-Open No. 10-29681 is known. In this known storage case, a rectangular first jacket, a second jacket, and a third jacket each having a bag-shaped storage portion are separately formed using a flexible vinyl sheet. These are made into a book-type configuration by heat sealing the side edges or the upper edge.
[0007]

BEST MODE FOR CARRYING OUT THE INVENTION
Next, the present invention will be described in detail based on specific embodiments.
First, a storage case according to the first embodiment is shown in FIGS. FIG. 1 shows a plan view of a blank material obtained by disassembling the structure of the storage case 1 according to this embodiment. In FIG. 1, a storage case 1 includes a first sheet material 2 and a second sheet material 3.
[0017]
As the first sheet material 2, for example, a transparent or translucent synthetic resin sheet having a certain degree of rigidity can be used, and the synthetic resin sheet formed in a long rectangular shape is used. A back cover part A, a back cover part B, and a cover part C as the storage case 1 are formed in series, and a folded piece 4 is formed on a free end side of the back cover part A by a fold 5. , And a folded piece 6 is also formed on the free end side of the cover part C via a fold line 7.
[0018]
The folded back piece 4 provided on the free end side of the back cover part A has its free end formed into a curved surface or an arc shape 4a, and a notch 4b extending from the center of the arc shape 4a toward the center. Is formed. A cut line 8 serving as one locking means of a required length is formed substantially at the center along the fold line 5, and the cut line 8 is formed in a shape slightly bulging outward from the fold line 5. . The cut line 8 may be formed at a position not along the fold line 5, for example, at a position slightly inside the fold line 5, that is, at a position indicated by a virtual line.
[0019]
The folded-back piece 6 provided on the free end side of the cover part C is formed to have a size of about half the width of the cover part C, and the insertion piece or tongue piece 9 serving as the other locking means along the fold 7 Are formed so as to form. The width of the tongue piece 9 substantially corresponds to the length of the cut line 8 provided along the fold line 5 on the back cover A side, and the tongue piece 9 is inserted into the cut line 8 so that the back cover portion is formed. Thus, the closed state of A and the cover C is maintained.
[0020]
Regarding the spine portion B, a fold 11 is provided at the center, a fold 12a having a predetermined width is provided on the cover portion C of the fold 11, and a virtual line 12b is provided from the fold 12a to the opposite side of the fold 11. The range up to the range indicated by is the spine portion B. In order to facilitate the process of attaching (heat sealing) the upper and lower edges of the spine portion B, cutout portions 13a and 13b are provided at the upper and lower edges of the front cover portion C adjacent to the fold line 12a. is there.
[0021]
The second sheet 3 is a protection sheet for protecting the recording surface of a disk such as a CD, and is formed of, for example, a nonwoven fabric, and has an arc shape corresponding to the shape of a CD to be stored. Portion 3a and a rectangular trapezoidal portion 3b are united with each other, and overhanging portions 3c and 3d are formed at the upper and lower edges of the trapezoidal portion 3b, and the size thereof is as a whole. It is formed in a size that does not protrude from the back cover part A.
[0022]
The second sheet 3 is basically formed of a relatively thick non-woven fabric having a moderate rigidity. However, when the non-woven fabric is relatively thin and soft, the second sheet 3 has a high rigidity. A backing made of a resin film material is used, and the protrusions 3c and 3d formed at the upper and lower edges of the trapezoidal portion 3b may be formed only on the backed film material.
[0023]
When the storage case 1 is formed using the blank material thus formed, as shown in FIG. 2, first, the fold 11 serving as the spine portion B of the first sheet material 2 is folded to form After folding, the fold 12a is folded outward so that the spine portion B overlaps and the front cover portion C is opened.
[0024]

On the front cover part C side, The fold 7 is folded inward to hold the folded piece 6 on the cover C, and in this state, the overlapping portion of the upper and lower edges is sealed over a predetermined width, for example, by heat sealing. The parts 14a, 14b, 15a, 15b, 16a, 16b are formed, and the overlapping portions become the first storage part 17, the second storage part 18, and the third storage part 19.
[0025]
In particular, in this heat sealing step, as shown in FIG. 3, heat sealing is performed with the second sheet material 3 interposed between the back cover part A and the folded piece 4. The overhanging portions 3c and 3d provided on the second sheet material 3 enter the sealing portions 14a and 14b, and the material is a non-woven fabric. However, the periphery of the overhang portions 3c and 3d is heat-sealed to form a firm sandwiching state, and the second sheet material 3 after the sealing is attached in a state where it does not easily come off.
[0026]
The position where the second sheet material 3 is disposed is a position slightly inside the edge formed by the crease 5, and a heading space 17a having a predetermined width is left on the edge side. Further, the distance between the two seal portions 14a and 14b formed at the upper and lower edges is formed to be slightly (about 1 to 3 mm) smaller than the diameter of a disk such as a CD to be stored. By forming in this manner, the stored disk moves to the edge side formed by the fold 5 and is held so as not to abut.
[0027]
For the heat sealing in this case, various sealing means generally used for a film or a sheet material can be applied. As shown in FIG. 4, for example, a large number of strip-shaped sealing elements 14c are provided. Even in the case of heat seals formed in a parallel state, regarding the relationship between the overhangs 3c and 3d provided on the second sheet material 3 in the seals 14a and 14b, the seal element 14c is Although it is difficult to substantially heat seal the overlapping portion, the portion deviating from the overhang portions 3c and 3d is tightly sealed to create a strong sandwiching state. The second sheet material 3 is attached without being easily pulled out.
[0028]
The projecting lengths of the protruding portions 3c and 3d that protrude into the seal portions 14a and 14b are preferably about half the width of the seal, but may be about 1/3 of the seal width. A good holding state is obtained. That is, the second sheet material 3 is not forced to be pulled when a CD or the like is put in or taken out, so that it is only necessary to stably maintain the arrangement state.
[0029]
