DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the accompanying drawings. The material is a compact disc (CD-
For example, a cardboard paper or a foamed synthetic resin sheet having a role as a cushioning material for protection of the ROM may be used.

[0011] The outline of the structure will be described with reference to FIGS. 1 and 2. A mailing case for a compact disc made of corrugated cardboard comprising a case body and a holder will be described assuming that a material having no risk of pollution is selected. . As shown in FIG. 1, the case body comprises a bottom portion 1 and four side walls 4 and 8 around the bottom portion. Extending flap pieces 5 are connected to one of two upper and lower opposing side walls 4, respectively. The flap pieces 5 are folded inward through the short side folds 3. Further, a locking piece 14 for preventing a storage item other than the compact disk, for example, a greeting, a manual, a postcard, a music lyrics card, etc. from protruding in a part of the fold 3 outside the short side fold 3. Is formed. In order to reduce the weight, an arc-shaped notch 21 having substantially the same diameter as the outer diameter of the compact disc is formed.

An outer cover 10 is connected to one of the other left and right side walls 8 via a long side fold 7.
Notch 30 for releasing the locking piece provided on the holder
Are provided in a row. In order to further reduce the weight, an arc-shaped notch 21 having substantially the same diameter as the outer diameter of the compact disk is formed, and a locking piece 11 is connected to the outer lid 10 via a locking piece fold 12. The bottom 1 of the case main body corresponds to the shape of the locking piece 11.
And a cutout portion 9 into which a part of the end of the compact disc can be inserted and engaged with a side wall 8 whose bottom 1 is connected to the outer lid 10.
A locking piece 11 is continuously provided on the other end of the outer lid 10, and a cut-out portion in which a part of the other end of the compact disc can be engaged with a portion serving as a side wall 8 formed when the locking piece 11 is bent. A case body provided with a compact disk 9 and, as shown in FIG. 2, a circular disk-shaped compact disk outer peripheral engagement notch 18 having a radius corresponding to the diameter of the compact disk are provided at both ends on the long side of the rectangular flat plate made of corrugated paper. As one example, the folding ruled line 27 is formed so that the left and right sides are averaged so as to guide the outer periphery of the compact disk when both ends on the long side are bent.
Are bent inward from the ruled lines 27 and bonded.

The short side folding guide piece 16 is formed with a cutout hole 22 for reducing the weight. Further, the first outer periphery of the compact disk is locked at the center of one of the outer periphery engagement cutout portions 18 of the shorter side folding guide piece 16 via a first cut 28.
A second engaging member that locks the other outer periphery of the compact disc through the second cuts 29 at both ends of the engaging protrusion 24 and both ends of the compact disc outer peripheral engagement cutout portion 18 of the other short side folding guide piece 17. The stop projections 25 are provided respectively.

In the holder 15 constructed as described above, both short side folding guide pieces 16 and 17 are folded inward and adhered to both ends of the main body of the holder 15, so that when the compact disc is placed on the holder 15, The outer peripheral portion is inserted below the first locking projection 24 and the second locking projection 25, so that the first and second locking projections 24,
The compact disc is held at two or more points by utilizing the elastic force of 25. At the approximate center of the rectangular flat plate, there is formed an engaging hole 19 with which the protective projection at the center of the compact disk is engaged. Further, a notch hole 23 for reducing the weight on the left and right is formed so as to sandwich the engaging hole 19. And the holder 15 formed. Then, the notch hole 23 is used to push up the first locking projection 24 to facilitate the insertion of the compact disc, thereby enabling the compact disc to be clamped, thereby simplifying the assembly and insertion.

Since the compact disk is held in the holder 15, there is no shift or scratch during mailing.

Therefore, the protection projection of the compact disk is engaged with the engagement hole 19 of the holder 15, and the projection at the center of the compact disk and the outer periphery of the compact disk are formed by embossing or crimping. 2
6, the surface containing the information of the compact disk can be floated and held so as not to be tight, and the first locking projection 24 and the second locking projection 25 formed on the holder 15 can be used as the compact disk. Both ends of the holder 15 for supporting the compact disk are bent inward, and the outer periphery of the compact disk is held. The holder 15 holding the compact disk is placed on the bottom 1 of the case body and the side walls 4, 8 and the extended flap piece 5 , And then folded so as to cover with the outer lid 10,
It is safe because it is a mailing case for a compact disk in which the outer lid 10 is bent so as to overlap the case body bottom 1.

More specifically, a sheet of relatively thin corrugated cardboard is punched and formed as shown in the unfolded state shown in FIG. 1 (note that it is also possible to laminate with a waterproof film in order to obtain waterproofness). Is). That is, as shown in FIG. 1, the bottom 1 of the main body, which fits within the standard for fixed-sized mail, has upper and lower side walls 2 on both upper and lower short side sides 2 through the short side folds 3, 3 as viewed in the longitudinal direction. 4, 4 and the extending flap pieces 5, 5 are provided continuously. Furthermore, a locking piece for preventing other storage items other than the compact disc, such as greetings, instructions, postcards, music lyrics cards, booklets, etc., from protruding into a part of the fold 3 outside the short side fold 3. 14 is formed so as to protrude when the upper and lower side walls 4 are bent. (It goes without saying that the number is one or more, as long as the protrusion can be prevented)

Also, as shown in FIG. 1, a left side wall 8 is connected to the left long side 6 via long side folds 7, 7 when viewed in the longitudinal direction, and a right side wall is further provided. An outer lid 10 is connected to 8. A locking piece 11 and a locking piece fold 12 are provided continuously at the outer end of the outer lid 10.
Further, a locking piece cutout hole 13 is formed so that the locking piece 11 is aligned with one end of the main body bottom 1 when the mailing case for a compact disc is assembled by bending.

The locking piece 11 and the fold 12 for the locking piece formed at the outer end of the outer lid 10 are not connected to each other, and the locking piece 11 is aligned with one end of the bottom 1 of the main body. Instead of forming the cutout hole 13 for the locking piece, it can be simply bent and locked at the end by an adhesive seal or the like. However, since the locking piece 11 and the locking piece cutout hole 13 are formed for the case made of corrugated paper, there is an advantage that the state of the temporary fixing can be maintained.

Since the cutout hole 13 for the locking piece is formed from one end as can be understood from FIG. 1, when the mailing case for a compact disc is assembled, it is necessary to make the cardboard cardboard flat. Cut out by the thickness of the paper.

The standard for fixed-size mail is at least 14 cm long.
23.5 cm or less, width of 9 cm or more, 12 cm or less, thickness of 1 cm or less, and weight of 50 g or less. However, since the compact disc is a disk and its outer diameter is about 12 cm, if it is completely covered with a case, it will exceed the limit of 12 cm which is the width of standard mail, and it will be outside the fixed form.
Postage will be higher.

In order to avoid this, a cut-out portion 9 is formed at a substantially middle portion of the side wall 8 connected to the outer lid 10 from the main body bottom portion 1 so that a part of the outer diameter of the compact disk can be engaged. A cutout 9 is formed between the lid and the locking piece 11 at substantially the middle of a piece corresponding to the side wall having the same height as the side wall 8 so that a part of the outer diameter of the compact disk is engaged.
When it is assembled, it is cut out so as to secure the standard of 12 cm on the short side, and only a part of the compact disc is exposed and can be stored therein. In addition, this is a mailing case for a compact disc in which the total weight of the case body and the contents of the compact disc can be made within 50 g.

As described above, in the unfolded state, the corrugated paper is punched and cut from the male plate surface side, punching of the outer shape corresponding to the ruled line, and the cutout hole 13 for the locking piece, each fold 3, 7, 1
2 is formed, a case body is obtained, and a compact disc sandwiched by a holder 15 and held by a holder 15 is mounted on the body body 1 on the case body, and the compact disk is bent as shown in FIG. It is something to assemble.

More specifically, when assembling the mailing case for a compact disc, as shown in FIG. 1, the inner side is turned up, in other words, the side on which the male plate is pressed is turned up. Then, the holder 15 holding the compact disk is placed on the bottom 1 of the main body, and the holder 15 is folded at the right long side fold 7, and the extended flap piece 5 on the long side is further folded while making up the right side wall 8. Bend.

Next, the upper and lower side walls 4 and the extended flap pieces 5 are bent through the short side folds 3, and the holder 15 holding the compact disc is covered so as to be pressed from above and below.

Finally, the outer lid 10 covers the holder 15 holding the compact disc and each extended flap piece 5 through the long side fold 7 to which the left outer lid 10 is connected. The locking piece 11 is bent through the folding cover 12 and further through the locking piece fold 12 to engage with the locking piece cutout hole 13 formed in the bottom 1 of the main body, and this portion is sealed with a seal or the like.

Next, the holder 15 will be described in detail with reference to FIG. Engagement made of a material having a thickness of CD and CD-ROM, for example, a rectangular flat plate of relatively thin corrugated cardboard, capable of accommodating standard mail, and in which a protective projection formed at the center of the compact disc can be fitted. A hole 19 is formed, and the short side folding guide piece 16 and the hook hole formed with the compact disk outer periphery engagement notch 18 are formed so as to guide the outer periphery of the compact disk engaged with the engagement hole 19. The short-side folding guide piece 17 is provided with a ruled line so as to be bent from the left and right, and is bent at the ruled line and adhered to the holder 15 main body to guide the outer periphery of the compact disc. .

When the display is to be lightened as shown in FIG. 2 in order to reduce the weight as much as possible, the hook hole 20 to be hooked on the locking member is provided with the short side folding guide piece 17 and the holder 15.
Notch holes 23 are formed on the left and right sides symmetrically with respect to the main body portion of the holder 15 so as to sandwich the engagement hole 19, and the short side folding guide piece 17 having the hook hole 20 is bent to overlap the main body of the holder 15. Is bonded.

When the compact disk held by the holder 15 is housed and assembled in the case main body as described above, the cut-out portion 9 formed at a substantially intermediate portion of the side wall 8 formed between the main body bottom portion 1 and the lid body 10 is formed. A portion of the outer periphery of the compact disc is held between the cutout 9 formed between the lid 10 and the locking piece 11 in a protruding state. Stopping piece 2
Four points are clamped by 4 and 25 and are mechanically held. Further, the size of the standard mail can be ensured within the standard.

Then, a sticker on which an address and an address are written is affixed to the outside of the bottom 1 of the main body, or the sticker is directly written and mailed. When storing the compact disk in a mailing case for a compact disk and storing it on a shelf or the like, a spine sticker is attached to the outside of the left side wall 8 shown in FIG. 1, or the content of the storage is directly described.

In order to remove the compact disc from the mailed one, the seal attached to the locking piece 11 is peeled off, the outer lid 10 is opened, and the holder 15 holding the compact disc is taken out. The compact disk can be easily taken out through the engagement hole 19 formed in the compact disk 15.

Although a specific embodiment has been described above, if the light weight is mainly designed, a light material (for example, styrene foam) can be used without increasing the cutout amount or considering the pollution. However, there are problems of strength and pollution. However, when designing mainly for strength,
Though thicker corrugated paper and fewer cut-out portions are conceivable, the weight increases and the postage increases.

Needless to say, various designs can be made to balance the above contradictory points in a well-balanced manner and to keep the total weight of the mailing case for compact disc and the compact disc within 50 g.

[0034]

According to the present invention, as a result of employing the above configuration,
The following effects can be obtained. (1) A compact disk can be set and handled as a fixed-size mail while ensuring prevention of breakage, and can be mailed at low postage. (2) Since the locking projection is formed on the holder and is sandwiched between the locking projections, the compact disc does not shift and is not scratched. (3) When managing compact discs, they can be placed side by side on a shelf while being delivered to a case. In addition, since the contents of the contents can be shown on the spine, the contents can be easily managed. (4) Greetings, manuals, postcards, music lyrics cards, etc.
It can be inserted and locked so that it does not fall down and can be mailed. (5) The compact disk is held in a floating state by the arc-shaped protrusion formed on the holder and the circular protrusion provided at the center of the compact disk, so that the compact disk is not scratched. (6) Since a proper number of case bodies and holders can be sold, transported, and stored in a flat state, handling is simple without bulk.
