Embodiments of the present invention will be described below with reference to the accompanying drawings.

In the first embodiment of the present invention, as shown in FIGS.
1 and the front sheet 12 are coupled in series, and a covering sheet 13 that is folded back on the back surface of the back sheet 11 is coupled to an edge of the back sheet 11. Also, on both side edges of the back sheet 11, folding pieces 14 that are folded toward the back surface of the back sheet 11 are provided.

Although the fold piece 14 is provided with a gore portion for providing a constant space between the opposing back sheet 11 and cover sheet 13 in the illustrated case, it is not necessarily required.

Further, one of the overlapping cover sheet 13 and the folded piece 14 is engaged with the through hole 15 and the other is engaged with the through hole 15 by penetrating the through hole 15 (as shown in FIG. 4). 16 are provided.

Although the above-mentioned locking piece 16 is coupled to the edge of the folding piece 14 in the drawing, for example,
There is a case where a slit such as a letter shape is provided and the number is not limited to one. Of course, one through hole 15 of the folding piece 14 and the locking piece 16 may be provided on the other.

Although the folded pieces 14 are provided on both side edges of the back sheet 11 in the illustrated case, they may be provided only on the cover sheet 13 side.

Naturally, when the folding piece 14 is provided on the back sheet 11 side, the folding sheet 14 is folded so as to overlap the front surface instead of the back surface of the covering sheet 13, and when the folding piece 14 is provided on the covering sheet 13 side, The sheet 11 is folded back so as to overlap one of the front and back surfaces.

With the above configuration, the back sheet 11
The plate-shaped body 3 is inserted together with the back cover 1 of the disk case A into a bag formed by the folding piece 14 and the covering sheet 13 which are engaged with the through hole 15 and the locking piece 16. .

At this time, the cover 2 of the disk case A
Is placed on the back surface of the front sheet 12.

On the free end side of the front sheet 12, a folded sheet 17 that is folded back on the back surface of the front sheet 12 is coupled.

Although the folded sheet 17 is connected to the free end of the front sheet 12 in the illustrated case, it may be connected to one side edge or both side edges.

The folded sheet 17 has a disk case A from one side of the folded sheet 17 to the other side.
Locking means 1 that allows the free end of the front cover 2 to pass through
8 are provided.

The embedment locking means 18 includes a hook piece 19 shown in FIGS. 2 and 3 and a single slit 20 shown in FIG.
And two slits 20 shown in FIG.

Then, the hook piece 1 of the embracing locking means 18
The free end of the front sheet 2 can be passed from one of the front and back surfaces of the folded sheet 17 to the other through the slit 9 and the slit 20, and the front cover 2 is held on the free end side of the front sheet 12.

The coupled connection portion between the back sheet 11 and the covering sheet 13 may be the whole (full length) or, for example, a partial portion at both ends.

In the second embodiment of the present invention, the covering sheet 13 is continuous from one side edge of the back sheet 11 as shown in FIG.

For this reason, the folding piece 14 to be fixed to the covering sheet 13 with the through hole 15 and the locking piece 16 is
Only one side edge is required. Of course, even though the free end side of the back sheet 11 is in an open state, there is no problem at all, and the folded piece 14 is not limited to the back sheet 11 but may be provided in the covering sheet 13, and the through holes 15 and The locking piece 16 may be provided in reverse.

The folded sheet 17 provided with the embrace locking means 18 provided on the front sheet 12 is the same as in the first embodiment, and a description thereof will be omitted.

When the cover sheet 13 is coupled to the back sheet 11 via the gore portion 13 'as shown in FIG. 7, a constant interval can be provided between the back sheet 11 and the cover sheet 13. Of course, the gore piece 14 is also provided with the gore portion 13 '.

According to the third embodiment of the present invention, instead of the cover of the first embodiment and the folded sheet 17 with the locking means 18 of the cover of the second embodiment, the front sheet 12 is provided on the free end side of the back surface. As shown in FIGS. 8 and 9, a bag sheet 31 having an open edge on the cover sheet 13 side is provided.

The above-mentioned bag sheet 31 is formed by folding a continuous sheet from the side edge or the edge of the front sheet 12 and fixing the overlapping side edges via heat fusion (fusion) or an adhesive, or another method. The edge of the sheet is fixedly provided in the manner described above.

Then, the free end of the cover 2 of the cover A is inserted inside the bag sheet 31, and the cover is mounted on the disk case A.

Of course, the back cover 1 and the plate 3 of the disk case A are inserted between the back sheet 11 and the covering sheet 13.

If a bag sheet 31 as shown in FIG. 9 is provided (opened at both ends), when the back cover 1 is extruded together with the plate-like body 3, the cover 2 is extruded (slid) together. Free end protrudes from inside the bag sheet 31.

In the fourth embodiment of the present invention, as shown in FIGS. 10 and 11, the front sheet 12 and the folded sheet 1 with the embedment locking means 18 are attached to the cover of the first embodiment.
Cover without 7 (can be used as case)
And

This cover (case) stores books, documents, and the like, and has gore portions 13 'on the edges other than the openings when the stored items are thick.

In the fifth embodiment of the present invention, as shown in FIGS. 12 and 13, the cover of the second embodiment is
A structure without the front sheet 12 and the folding sheet 17 with the embedment locking means 18 is used as a cover (can be used as a case).

This cover (case) stores books, documents, and the like, and has a gore portion 13 'on the periphery other than the opening when the storage object has a thickness. Of course, a cover (case) may be provided with a lid.

In the sixth embodiment of the present invention, as shown in FIGS. 14 and 16, the cover for the disk case shown in the first to third embodiments and the fourth and fifth embodiments are used. The through hole 15 of the cover shown is
When the back sheet 11 and the cover sheet 13 are folded flat,
The locking pieces 16 are long holes that can move inward in the through holes 15.

Then, flat folding as shown in FIGS. 15 and 17 becomes possible, and the bulk before use can be reduced, that is, the assembled cover can be folded flat.

The through-hole 15 may have a hook-like shape with an open inward end as shown in FIG.
However, the side edge of the locking piece 16 abuts on the outward edge of the through hole 15, and the gore portion 13 'and the folding piece 14 are stopped at an accurate position.

Although the cover of the disk case is shown in the drawing, the present invention is also applied to the case.

Although the folded piece 14 is present at a part of the side edge, it may be provided at the entire length of the side edge or partially.

[0046]

As described above, the cover for a disk case according to the present invention forms a back sheet, a front sheet, a covering sheet, a folding piece, and a folded sheet with engaging means by one sheet. Since the covering sheet and the folding piece are stopped by the through hole and the locking piece, there is no need to process the bag sheet or the bag portion (fixing work using heat fusion or an adhesive). Therefore, the cost can be significantly reduced.

Further, even with a cover having a bag portion provided on the free end side of the front sheet, the process of providing the bag sheet becomes unnecessary. For this reason, the processing time is reduced by half, and the cost can be reduced. Furthermore, a back sheet, a covering sheet, and a folding piece are formed by one sheet, and the covering sheet is opposed to the back sheet with the through holes and the locking pieces to form a cover. This eliminates the need for the fixing operation using the slab, thereby significantly reducing the cost. In addition, since the locking piece can be moved inward in the through hole, the cover can be folded flat to reduce the volume before use.
