Description

  The present invention relates to a simple disc case that does not require bonding, fixing, or the like, which can be performed by punching a single sheet.

  Disc cases such as CD (compact disc) and DVD (digital versatile disc) have various forms and materials. In particular, 5 mm thick 12 cm CD / DVD polystyrene cases are used in large quantities because they are compact and have high disc protection. In addition, since the thickness is only 5 mm, it is convenient not to take a place when storing the disc stored in the case. However, since it is a plastic molded product, there are problems such as disposal of the case, and the contents of the disc cannot be directly written or printed with a writing instrument such as a pencil or ballpoint pen on the case exterior surface including the back cover. there were.

On the other hand, many proposals have been made to obtain thin disk cases by bending and bonding paper or plastic sheets that do not require plastic molding. In cases where sheets are folded and bonded, how to fix the disk firmly to the case is a problem that is not possible with molded products, but simple disk fixing methods (Patent Documents 1, 2, and 3) have been proposed and implemented. Yes.

  If the disk fixing method shown in FIG. 7 and FIG. 8 which explains the conventional paper product in Patent Document 1, the disk is completely fixed to the mount by this alone, and the disk is not required to be covered or covered. This method is excellent in that it does not move or drop out. Although this is also used in Patent Document 2, a common problem is that 130a and 130b shown in FIG. Patent Document 1 and Patent Document 3 do not require adhesion, but the disk has a possibility of dropping off in the state where the lid or cover is not attached.

  The problems to be solved by the present invention are as follows. In other words, simply folding a single sheet does not require adhesive fixing, and covers the disc with a lid or cover, holds the disc firmly without locking the lid, and does not have to worry about dropping out Is to provide.

  The first problem solving means is that a disk holding piece is extended via a crease on the upper and lower edges of the rectangular mount sheet, and an arc-shaped cut is formed at the center of both disk holding pieces so as to face the cut opening. A rectangular cover sheet having fold lines from both ends of at least one arc-shaped cut to the left and right edges of the disc pressing piece, and at least one fold line on at least one of the left and right edges of the rectangular mount sheet. The disc case is made of a single sheet, and can be assembled without bonding anywhere.

  The second problem-solving means is that the rectangular mount sheet and the rectangular cover sheet are connected by a back cover portion composed of two fold lines, and the same edge of the rectangular cover sheet on the side opposite to the spine cover portion is folded. The disc case according to the first problem solving means described above is characterized in that a locking piece is extended through a spine portion made of a streak.

  Conventionally, a disc case that consists of a single sheet and is not glued or fixed will lock the disc firmly when the lid is closed or locked, but the disc may drop off before the lid is closed Cannot be denied. Further, in order to firmly fix the disc case even before the lid is closed, the disc pressing pieces 130a and 130b have to be adhered to the mount as shown in FIGS. However, according to the present invention, the disk is firmly fixed to the disk holding piece without being bonded and fixed anywhere, that is, the disk holding piece is bonded to the mount, and the lid is closed without being fixed. Will disappear.

  In addition, there is only punching a single sheet of paper, or the like, can be produced at the cheapest cost, the use of the paper sheet, on any surface, including the spine, the contents such as a disk of title pencil, such as ball-point pen usually You can write with a writing instrument and write the contents of the disc on the back cover, so when storing a large amount of discs and searching for the target disc from among them, look at the back cover from the state of being on the shelf etc. It is a great merit to be able to find the discs. The conventional plastic case is the cheapest, and it has been impossible to find a spine cover disc with a thin 5 mm thick disc case. However, according to the present invention, it can be made simple and inexpensive.

  FIG. 1 shows a development view of this embodiment. The sheet is a coated paper having a basis weight of 310 g / m2. In the actual battle, the cut line is shown, and the dotted line shows the crease. The disc pressing pieces 3 (3a, 3b, 3c, 3d, 3e), 4 (4a, 4b, 4c, 4d, 4e) are extended to the upper and lower edge pieces of the rectangular mount sheet 1 through the folding lines 8, 9. Yes. The disc pressing pieces 3 and 4 are provided with arc-shaped cuts 3c and 4c, and fold lines 3d and 4d are provided from both ends of the arc-shaped cuts 3c and 4c. A rectangular cover sheet 2 is extended on the other edge of the rectangular mount sheet 1 via a spine cover 7a composed of two folding lines. A locking piece 5 is extended from the leading edge of the rectangular cover sheet 2 via a spine cover 7b made of two fold lines.

  FIG. 2 is a plan view showing a state in which the disc pressing pieces 3 and 4 of FIG.

  3, in the state of FIG. 2, an appropriate arc side of the disk D 1 is inserted into the arc-shaped cut 4 c of the disk pressing piece 4, and the edge on the opposite side of the disk is bent by the folding line 3 d of the disk pressing piece 3. It is a perspective view which shows the state put on the disk holding | suppressing upper piece 3b.

  FIG. 4 shows a state in which the upper and lower disk pressing pieces 3 and 4 are bent at the folding lines 3d and 4d, and the disk D1 is inside the arc-shaped cut pieces 3e and 4e, and the upper disk pressing pieces 3b and 4b in the state of FIG. It is a perspective view which shows the state put on.

  FIG. 5 shows that the disk D1 is firmly rectangular from the state shown in FIGS. 3 and 4 by pushing the disk D1 with the finger toward the rectangular mount sheet 1 from the outside with the arc-shaped pieces 3e in FIG. 3 and the arc-shaped pieces 3e and 4e in FIG. It is a perspective view which shows the state hold | maintained and fixed to the mount sheet. The disk D1 is pressed by the arc-shaped pieces 3e and 4e, and the disk D1 presses the disk pressing upper pieces 3d and 4d, and it can be understood that the disk and the disk pressing piece are pressing each other. That is, this is a perspective view showing that the disk can be easily held and fixed to the mount without bonding and fixing the sheet anywhere. 6 shows a plan view of the state of FIG. FIG. 7 is a sectional view taken along line XX in FIG. 8, the rectangular cover sheet 2 is placed on the disk D1 from the state of FIG. 5, the locking piece 5 is bent to the rectangular mounting sheet side, and the locking tongue 5 a is inserted into the locking hole 6 of the rectangular mounting sheet 1. Indicates the state.

  As shown in FIGS. 9 and 10, the present invention can be designed to accommodate two discs, and it goes without saying that it is possible to accommodate more than this. In addition, it is apparent that the arc-shaped piece of the disk pressing piece is not necessarily a complete arc as shown in FIGS. Further, as shown in FIG. 11, the arc-shaped piece is easily opened by opening the extraction windows 3f and 4f so that a part of the disk protrudes to the opposite side of the arc-shaped piece and is angled with respect to the rectangular backing sheet of the disk holding piece. In addition, the disk can be easily locked by the disk pressing piece. The disk held and fixed according to the present invention can be easily released by pinching the tips of both arcuate pieces with a finger and pulling it upward. According to the present invention, the holding and fixing of the disk to the case can be performed with a single action, and the release can be performed with a single action, and it is thin, inexpensive, and can be written on the spine cover.
