[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixed postcard-sized mailing case capable of securely and reliably mailing a floppy, negative, positive, letter, etc., to a mailing case for a floppy, the mailing case itself having a weight of 25 g or less. It is.

[0002]

2. Description of the Related Art Conventionally, a cushioning material having an air layer is provided between two synthetic resin sheets attached to paper in an envelope. Alternatively, a cushioning material such as Styrofoam is inserted, and a floppy is sandwiched between the cushioning materials and mailed.
Further, as an assembled paper box having a paper box main body, an outer lid, and an inner lid, the paper box main body is composed of a bottom portion, four side walls of the paper box, and connecting pieces formed between left and right end portions of each side wall. Each of the side walls is formed into a double wall having an outer wall and an inner side wall by folding an inwardly extending member connected to the bottom of the main body, and the folded front end is attached to the bottom of the main body. An outer lid is continuously provided on one side wall upper end of one of the two side walls facing each other, and an inner lid is continuously provided on the other side wall upper end, and an extension piece for closing is formed at the end of the inner lid, There is an assembled paper box (see Japanese Utility Model Laid-Open No. 58-67732) in which a diagonal fold is formed on the connecting piece so as to be folded inward.

[0003]

However, in the case of the above-mentioned prior art envelope in which a cushioning material is interposed and a floppy is sandwiched between the cushioning materials and mailed, the weight is first kept within 25 g. Is a difficult technique. Moreover, there is a problem that the disposal of the cushioning material causes pollution.

Further, the conventional assembly paper box is a folding box made of paper instead of mailing a floppy disk, but there is a problem that the weight is not taken into consideration at all.

In view of these circumstances, the present invention requires that the weight of the floppy mailing case itself be less than 25 g in order to ensure that the floppy is safe and does not cause a pollution problem, and that the weight of the floppy mailing case itself is less than 50 g in relation to the shipping cost. An object of the present invention is to provide a mailing case for a floppy disk which solves the problem.

[0006]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a cardboard paper assembly floppy mailing case having a case body, an outer lid, and an inner lid, wherein the case body has a bottom portion and four circumferences thereof. An extension member is continuously provided on each of the two upper and lower side walls that face each other, and the extension member is folded back inward. An outer lid is continuously provided on one of the right and left side walls opposite to each other, an inner lid is continuously provided on the other side wall, and a locking piece is continuously provided on the outer lid, which corresponds to the shape of the locking piece. As shown in the figure, a cutout hole of the same shape is drilled in the bottom of the case body, a bent piece is formed around three of the four circumferences of the inner lid, and a floppy insertion cutout part that can be formed by bending the three bent pieces is provided. Is formed with a fillet portion that engages with a notch formed in one corner of the floppy disk, and a polygonal hole for taking out the floppy disk is provided around the remaining one to provide a bending piece. Is bent approximately 180 degrees so as to be doubled, the inner lid is further bent to the case body side through the side wall of the case body, and then the outer lid can be folded so as to overlap the inner lid. Adopted technical means.

[0007]

According to the present invention, as a result of employing the above technical means, first, since the case is made by folding and assembling corrugated paper into a box shape, the present invention can withstand a large external bending force in the left, right, up and down directions. Then, in order to easily take out the inserted floppy disk, the cutout hole is utilized to the maximum to reduce the weight, and the cutout hole is used to facilitate the taking out with a finger. Furthermore, since the floppy cutout hole is formed so that the cutout portion at one corner of the floppy to be stored is exactly engaged with the storage of the floppy, the directionality can be ensured. Therefore, when the external force is applied, the weakest part is located in the part where the external force is hard to apply, so that the safety against the floppy disk is further enhanced. Moreover, without using any cushioning material that may cause pollution, it is possible to securely and safely mail the floppy with only paper. If the contents name is written on the back of the floppy mailing case for use, it can be managed very effectively if it is stored side by side on a shelf or the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the accompanying drawings. The outline of the configuration is as follows: In a corrugated cardboard assembly floppy mailing case having a case body, an outer lid 10 and an inner lid 9, the case body is composed of a bottom portion 1 and four side walls thereof, and one of the upper and lower ones faces each other. An extension member 5 is continuously provided on each side wall 4, and the extension member 5 is folded back inward. An outer lid 10 is continuously provided on one of the other left and right side walls 8 facing each other, an inner lid 9 is continuously provided on the other sidewall, and a locking piece 11 is continuously provided on the outer lid 10. A cutout hole 13 having the same shape is formed in the bottom portion 1 of the case main body so as to correspond to the shape of the piece 11, and a folding flap 18 is formed around three of the four circumferences of the inner lid 9, and the three folding flap 18 is bent. A floppy insertion cutout that can be formed is provided, and a fillet portion that engages with a notch formed in one corner of the floppy is formed in one corner, and a finger for taking out the floppy disk can be inserted in the remaining one periphery. Square holes are provided, trapezoidal folding flaps 20 are provided, and the respective folding flaps 18 and the trapezoidal folding flaps 20 are folded by approximately 180 degrees so as to be doubled. This is a floppy mailing case in which the inner lid 9 is further bent to the case body side through the side wall of the case body, and then the outer lid 10 is bent so as to overlap the inner lid 9.

More specifically, one sheet of relatively thin corrugated paper is punched and formed as in the developed state shown in FIG. 1 (it is also possible to laminate with a waterproof film to obtain waterproofness). Is). That is, as shown in FIG. 1, the bottom 1 of the main body of a fixed postcard extends from the upper and lower short sides 2 to the upper and lower side walls 4, 4 via the short side folds 3, 3 as viewed in the longitudinal direction. The pieces 5, 5 are provided in series.

Also, as shown in FIG. 1, left and right side walls 8 and 8 are connected to each other on both long sides 6 on the left and right sides when viewed in the longitudinal direction via long creases 7 and 7 on the long sides. An inner lid 9 is connected to one of the left and right side walls 8 and 8, and an outer lid 10 is connected to the other. A locking piece 11 and a locking piece fold 12 are continuously provided on the outer end portion of the outer lid 10. Further, a cutout hole 13 for a locking piece is formed at one end of the main body bottom portion 1 so that the locking piece 11 is aligned when the folding and assembling the floppy mailing case.

The cutout hole 13 for the locking piece is formed from one end as can be understood from FIG. 1, so that when the mailing case for a floppy disk is assembled, it is necessary to make the height equal to that of the corrugated paper. In this case, the bent pieces 15 are formed on the left and right side walls 8 via the bent piece folds 14 also as reinforcement.

Next, the floppy insertion hole 21, which is a cutout portion for accommodating the floppy in the inner lid 9, will be described in detail. So that you can insert a 3.5 inch floppy
A diagonal cut 16 is formed at the upper left corner so as to match the notch at one corner formed on the floppy, and a shape substantially matching the size of the floppy so as to be connected to both ends of the diagonal cut 16 Are formed, and a flap 18 is formed by folding the upper and lower three pieces so as to be bent by the square fold 17.

Then, a cut is made one size slightly smaller than the size of the floppy, and a cut is made at an angle of 45 degrees toward the upper right corner, and a cut is made at the upper left corner. Make a cut until Then, only one piece on the lower side is cut at an angle of 45 degrees from the left and right corners of the lower side as shown in the figure in order to make a finger insertion hole 19 so that a finger can be inserted when the floppy disk is taken out. Extends the trapezoidal folding flap 20
Is formed, and by utilizing this portion, a substantially hexagonal finger insertion hole 19 is formed.
To drill. In addition, this substantially trapezoidal folding flap 20
As shown in FIG. 1, the substantially hexagonal finger insertion hole 19 is bent diagonally, resulting in a substantially trapezoidal finger insertion hole 19.

As described above, the corrugated paper is punched in the unfolded state, and is sequentially folded and assembled as shown in FIGS. 2 to 5 using the folds 3, 7, 12, 17 corresponding to the ruled lines. .

More specifically, when assembling the mailing case for floppy,
As shown in FIG. 1, the upper and left folding flaps 18 are folded 180 degrees inward through a square fold 17 formed in the inner lid 9 so as to be doubled, and further, the lower square fold 17 is formed. , The trapezoidal folding flap 20 is folded 180 degrees to the same inside so as to be doubled so that the floppy can be stored. Then, necessary negatives, positives, messages, etc. are placed on the bottom 1 of the main body, and the inner lid 9 is completed while folding the right side wall 8 at the long side fold 7 on the right side, and the floppy is inserted into the floppy insertion hole 21. insert.

Next, the upper and lower side walls 4 and the extension piece 5 are bent through the short side folds 3 and the inner lid 9 is covered so as to be pressed from above and below.

Finally, the outer lid 10 is folded so as to cover the inner lid 9 through the long side folds 7 on which the left outer lid 10 is continuously provided, and further, the locking piece folds 12 are provided.
, The engaging piece 11 is bent to engage with the engaging piece cutout hole 13 formed in the bottom 1 of the main body, and this portion is sealed with a seal or the like (see FIG. 5).

Then, a sticker on which an address and an address are written is attached to the outside of the bottom 1 of the main body, or the sticker is directly written and mailed. When the floppy is stored in the mail case for the floppy while being stored in a shelf or the like, a spine cover sticker is attached to the outside of the left side wall 8 shown in FIG. 1 or the contents of the storage are directly described.

In order to take out the floppy from the mail, the sticker attached to the locking piece 11 is peeled off, the outer lid 10 is opened, and the finger is inserted through the substantially trapezoidal finger insertion hole 19. The floppy can be easily removed.

If the amount of cutting is increased, the weight becomes lighter, but a problem of strength arises. Therefore, the portion to be cut out is determined by maximizing the portion that needs to be cut out. Nevertheless, it was considered in terms of strength.

Although a specific embodiment has been described above, if the light weight is mainly designed, a light-weight 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, if you mainly design strength,
Though it may be possible to use thick corrugated cardboard or reduce the cutout portion, the weight becomes heavy and the postage increases.

It goes without saying that various designs can be made to balance the above contradictory points in a well-balanced manner and to keep the weight of the mailing case within 25 g.

[0023]

As a result of adopting the above configuration, the present invention provides
The following effects can be obtained. (1) Since paper is the only material used, pollution problems do not occur. (2) Since it is a fixed size and can be stored within 50g including a floppy, it can be sent by cheap postage. (3) When the floppy is stored, the weakest portion is positioned at the strongest portion of the case when an external force is applied, so that the floppy is hardly damaged. (4) When managing floppies, they can be placed on a shelf while being delivered to a case. Moreover, since the contents of the contents can be shown on the spine, it can be easily managed. (5) Since the case body, the outer lid, and the inner lid can be stacked, sold, transported, and stored in a flat state while being integrated, they are not bulky and are easy to handle.
