The outer shape in the length direction is composed of and. The dimension of the insertion opening 26 in the width direction is set to be slightly larger than the width of the video tape T by about the thickness of the folded long piece 16 or 17.

A slit 20 is formed at a fold line 13 portion between the upper lid portion 14 and the insertion piece 15, and a tongue piece 22 extending through the fold line 21 is provided at an upper edge of the front face portion 10 facing the slit 20. Further, notches 23a, 23b parallel to the inner side of the base end fold line 21 of the tongue piece 22 and a fold line 23c connecting the base end portions of these notches are formed to separate the tongue piece 22 from the front surface portion 10. By forming a bent portion 23 that is bent at a time, it can be inserted into the slit 20 when the case 1 is formed.

Here, the length of the folding long pieces 16 and 17 serving as the inner lid that closes the insertion opening 26 is increased because the strength in the thickness direction at the time of forming the box body is the folding long pieces 16 and 17. It is for storing by interposing 17 between the front part 10 and the back part 2. Further, it is also for preventing backlash when the DM copy P is not inserted by folding it inward, so that a cushioning effect is exhibited.

Further, the bottom lid forming portions 18 and 19 have the same shape as is apparent from FIG. 2 and are combined as shown in FIG. Can be formed. Each bottom lid forming portion 18, 19 is provided with a step having a thickness about half that of the case at the center of the back surface 2 in the width direction, and this step has a protruding insertion portion 18a having a length about the thickness of the case 1, 19a and insertion recesses 18b, 19b arranged so as to face the mating protruding insertion portions are formed. 18c, 19c
Is a bent portion formed through the valley crease lines 24, 24 to obtain the above-described allowable insertion movement, and 18d, 19d are mountain crease lines 25, 25
It is a sticking part that is bent through and is stuck to the inside of the box body by gluing or the like.

Further, according to the above-mentioned configuration, the back surface part 2, the pair of side surface parts 5, 6 and the side surface part 10 are bent along the respective fold lines to form a box-like shape with the sticking piece and to form the bottom lid. Department
The bottom opening is closed by 18,19, and in that state, case 1
The video tape T is stored inside, and the long strip 1 on the side 5 and 6 side
The upper opening is closed with 6,17 and the insertion piece 15 is inserted to overlap the upper lid portion 14, and the tongue piece 22 is cut 23
The tongue piece 22 is bent so that it is lifted by a and 23b and the crease line 23c.
It can be mailed by inserting the into the slit 20 and locking it so as not to open the upper opening.

In particular, as shown in FIG. 4, if the video tape T is inserted from the insertion opening 26, it can be easily inserted with a large width G, G. At that time, the position is fixed in the thickness direction by inserting the DM copy P or the like in the thickness direction. In addition, as shown in FIG. 5, when the DM copy or the like P is not inserted, the folding length pieces 16 and 17 are folded inward to reduce the width direction dimension,
It is inserted without play.

For VHS type, case length 189 to 197 mm, case width 105 to
Good results were obtained by conducting the test in the range of 110 mm and case thickness of 25 to 30 mm.

101-250 for first-class non-standard size mail (as of April 1989)
Shipping costs of 250 yen for g and 360 yen for 251-500g. In the case of standard 15 minute VHS tape (hereinafter referred to as "15 minute tape"), the weight of bare tape is in the range of about 185 ~ 192g, and in order to reduce the shipping cost to 250 yen postage, Maximum allowable weight 250g to 15 minutes Minimum tape weight 18
The remaining weight of 65 g after subtracting 5 g is the maximum weight that is effective as a case. If the case exceeds this 65g, 15
The shipping cost of one step higher (360
Yen) is required.

It has been found that a case having a minimum area necessary to accommodate a video tape can be sufficiently constructed even with a weight of, for example, 30 g. Therefore, even if the 15-minute tape has a maximum weight of 192 g, it will be 222 g at +30 g, and there is a margin of 28 g by the maximum allowable weight of 250 g. In this case, it is possible to enclose several printed materials such as A4 DM copies. If you don't include anything, you can set the case weight up to 58g for a 15-minute tape.

In addition, standard 30-minute and 40-minute VHS tapes (hereinafter referred to as "30-minute tapes" and "40-minute tapes") are approximately 201 to 213, respectively.
g, weight in the range of about 203-220 g. Even with the maximum weight of 213 g, the 30-minute tape still has a margin of 7 g, and even in this case, it is possible to enclose one printed matter. Also, with a 40-minute tape, the maximum weight of 220 g can be reduced to 250 g in calculation only when the printed matter is not enclosed,
Can be mailed.

In this way, instead of simply pursuing economic efficiency, it is possible to send mail at a slightly lower price in accordance with the postal charge system, which enables economical mailing in consideration of postage.

It should be noted that the present invention is not limited to the structure of the embodiment described above, and the shape and structure of each part can be appropriately modified or changed as necessary. For example, in the above-described embodiment, the bottom opening is closed by the structure shown in FIG. 3, but as is apparent from FIG. 6, the side folding long pieces 30a and 30b are used. It is easy to understand that it is good.

[Effect of device]

As described above, according to the present invention, a housing space that is approximately equal to the outer shape of the video tape is formed in the case, and in particular, the space between both side surfaces is made thicker than the outer shape of the video tape by the thickness of the plate material. When the piece is overlapped with the inner wall surface of each side surface portion, a guide surface approximately in the width dimension of the video tape is formed from the insertion opening toward the inside of the case, and smooth insertion without play can be realized. .

Also, even if the case is made thinner in the thickness direction by conforming to the outer shape of the video tape, the thickness of both side and bottom parts has a double structure, so the strength of the case frame is improved and twisting in the mail is avoided. It is possible to obtain the shape-retaining effect of sufficiently withstanding the addition of a load or the like. In addition, since the above-mentioned double structure plays a role of a cushion, it is possible to absorb an external impact and protect the video tape satisfactorily.

In addition to the above, one plate material has a minimum required area that almost fits the outer shape of the video tape, which further reduces the weight of the entire case, ensuring safety during mailing. The shipping cost can be kept to the minimum necessary amount. For example, when a conventional video tape case was placed in a dedicated cushion envelope and sent by mail, a mailing cost of more than 250g (360 yen) was required. However, in the case of the present invention, 250g or less The postage (250 yen) is enough, and its practical effect is great.
