[Field to which the invention belongs]

 The present invention mainly relates to a case suitable for transferring a plate-shaped recording medium such as a compact disk or a floppy disk.

[0002]

[Problems to be solved by conventional techniques and devices]

 In recent years, compact discs (hereinafter referred to as CDs) have appeared on the market in the fields of computer software, music, and video. Correspondingly, there are increasing opportunities to send CDs by mail, home delivery, in-house courier, or other transportation means.

Usually, a CD is housed in a hard plastic case, but the plastic case is composed of three members, a main body, a lid, and an insole, which are injection-molded, respectively. Is expensive. Also, since the case is easily broken by impact, it is time-consuming to wrap the case with a cushion sheet before sending it. In addition, the weight of the case itself is heavy, and the thickness of the cushion sheet makes it bulky, which is disadvantageous for transportation. The present invention clarifies a case where the above problems can be solved.

[Embodiment of the invention]

 FIG. 1 is an exploded perspective view of a CD housing case. The plate body (1) which is the material of the case has a length of 525 mm, a width of 150 mm and a thickness of 3 mm. The plate body (1) is divided into three parts of a front plate (2), an intermediate plate (3) and a back plate (4) of the same length in the longitudinal direction, and the plate plate (1) is exposed on both sides of the intermediate plate (3). It is folded in three so that the plate (2) and the back plate (4) overlap.

As shown in FIG. 3, the plate body (1) is formed by joining paper sheets (11) and (11) on both sides of a lightweight foamed resin plate (10) having a thickness of less than 3 mm. At the boundary between the front plate (2) and the intermediate plate (3) of the plate body (1) and the boundary between the intermediate plate (3) and the back plate (4), bending notches (12) and (12) are provided inside. It is applied with the paper sheet (11) left.

Since the front plate (2) and the intermediate plate (3) are bent in opposite directions, the two notches (12) (12) are formed on the opposite surfaces of the plate body (1). A circular through hole having a diameter of 120 mm is opened in the intermediate plate (3), and a finger insertion notch (32) is formed at the hole edge on the side far from the front plate (2). A cut (13) for folding is made on the inner surface of the front plate (2) at a position approximately 35 mm from the boundary between the front plate (2) and the intermediate plate (3) in parallel with the boundary, and the cut is performed. The cover (21) extends from the boundary (13) to the front plate (2) and the intermediate plate (3), and the cover (22) extends from the notch (13) to the outside.

Both ends of the boundary between the front plate (2) and the intermediate plate (3) and both end portions on the front end side of the back plate (4) are formed by bending the front plate (2) and the back plate (4). When it is piled up on 3), both ends on the folding side of the front plate (2) are cut (14) (15) so that they are rounded. Bend the back plate (4) with the notch (12) and bond it to the intermediate plate (3), and bend the front plate (2) with the notch (12) and only the cover part (21) to the intermediate plate (3). By adhering, a case with a width of 175 mm, a length of 150 mm and a thickness of less than 10 mm is completed. The covering portion (21) covers a part of the through hole (31) of the intermediate plate (3).

However, the lid portion (22) is opened from the notch (13) of the front plate (2) to accommodate the CD (5) in the through hole (31) of the intermediate plate (3). A part of the through hole (31) is hidden by the cover portion (21) of the front plate (2), but if it is shifted from the side, the CD can be easily inserted into the through hole (31).

As shown in FIG. 4, if an envelope having a size corresponding to the case is prepared in advance and the case is inserted into the envelope from the rounded side, the case can be smoothly inserted without being caught.

Since the plate body (1) is formed by sticking the paper sheets (11) and (11) on both sides of the foamed resin plate (10), it has cushioning properties, and further, the double-sided sheet (11) (11) supplements the strength of the foamed resin plate (10), and the plate (1) of the case is tripled in the case, so it has sufficient strength for ordinary transportation means such as mailing and home delivery. Even if an impact is received during transportation, it is possible to prevent damage to the CD contained therein.

Further, the plate body (1) is lightweight, and the weight of the whole case is suppressed to about 25 g, which is a significant weight reduction as compared with the conventional hard plastic case for CD of about 70 g. Also, since it is not necessary to wrap the case with a cushion sheet, the bulkiness is suppressed, which is extremely advantageous for transportation such as mailing.

Further, the contour of the plate body (1), the punching process of the through hole (31), and the machining of the notches (12) and (13), that is, the front plate (2), the intermediate plate (3) and the back plate ( The paper sheets (11) and (11) in which 4) are connected by one thin skin can be manufactured in one process by a punching machine for paper plates called Thomson, and can be efficiently manufactured. Further, since the plate body (1) can be accurately punched into a rectangle having a predetermined size because it can be processed in one step, the notches (12) and (13) are also formed on the side edges in the longitudinal direction of the plate body (1). It can be applied at a right angle to the case, and when the case is finished, the end faces of the case are flush with each other and do not impair the commercial value.

The case can be assembled by simply folding the plate body (1) in three and adhering the necessary parts. Therefore, like the conventional hard plastic case, the lid, body and insole are separated by injection molding. The cost can be drastically reduced compared to the one that is molded and assembled.

The case and the envelope can be set in advance by putting the case in the envelope (6). In this case, in order to store the CD in the case, the entire lid part (22) is exposed from the envelope (6), but the covering part (21) is removed from the envelope (6) to the state where it is inside the envelope (6). Pull out, open the lid part (22) in this state, store the CD in the case and push the case into the envelope, and the lid part (22) will hit the opening edge of the envelope and close it naturally. It is housed in 6), and the case and envelope are not caught, making it convenient and easy to use.

The case may be directly marked with an address and mailed. In this case, the lid part (22) and the intermediate plate (3) may be joined by a joining means such as a double-sided tape (7) or a surface fastener. When removing the CD from the case, even if the lid part (22) is opened, the cover part (21) of the plate body (1) covers part of the CD, so the CD will not accidentally fly out of the case, CD damage can be prevented. CDs can be taken out without difficulty by inserting fingers into the notches (32) for inserting fingers.

In carrying out the present invention, the plate body (1) may have resin sheets adhered to both surfaces of the foamed resin plate (10) by welding or the like. In this case, the case is resistant to water wetting. The plate body (1) can also be implemented by a corrugated cardboard sheet.

Further, the case of the present invention is particularly effective as a case for transferring a plate-shaped recording medium such as a CD or a floppy disk, or a plate-shaped article such as a plate chocolat, which is easily broken. By increasing the thickness of), not only plate-like articles but also thick articles can be accommodated, and various modifications are possible within the scope of the utility model registration claim.
