2. Description of the Related Art Conventionally, an assembling type packaging box whose size can be appropriately changed is used for packaging products. ,In particular,
When the size of the article to be packaged is not constant, a prefabricated packaging box configured to be folded and packaged according to the size of the article to be packaged is used. For example, when mailing a product such as a book or a magazine that has a uniform shape but a different thickness depending on the number of books, a folding piece and a lid that can be freely folded so that the size can be accommodated. Assembled packaging boxes with parts are used.

FIG. 6 shows a typical assembly type packaging box which has been conventionally used. Two corrugated cardboard folding pieces 3, 3 are provided on both sides of a central portion of a rectangular corrugated cardboard main body 1 so as to have a substantially cross shape. The folding pieces 3, 3 are
It is integrally assembled by adhering the end edge portion 3a shown by diagonal lines, but the non-adhesion portion 5 having a constant width is provided on the end edge side of the main body piece 1. In the main body piece 1, a portion formed by attaching the folding piece 3 is a bottom portion 6, and both protruding end portions are lid portions 8.

Next, a method of using the assembling type packaging box having the above structure will be described. First, with the main body piece 1 and the folding pieces 3 and 3 opened (FIG. 6), the product H such as a book is placed on the bottom portion 6 with the end edge portion 3a of the folding piece 3, and then the folding piece 3 is placed. Is folded so as to wrap around the end of the product H, and both ends thereof are overlapped.

After that, the lid portion 8 of the main body piece 1 may be folded and wrapped, and the end portions may be overlapped and attached, or may be bound with a string. Since the non-sticking portion 5 protrudes and functions as a cushion that absorbs shocks, even a rough handling during mailing does not damage products such as books.

[0006]

However, the above assembling type packaging box has the following problems. That is, since the folding pieces 3 and 3 are attached to the body piece 1, a number of steps such as cutting and attaching are required for manufacturing,
It takes time and effort to manufacture, resulting in higher costs. Further, since the folding pieces 3 and 3 are attached to both end edges of the bottom portion 6 by hand, the inner edges of the folding pieces 3 and 3 and the outer edge of the bottom portion 6 are attached in parallel. It is difficult to wear, and both may be attached in an inclined state.

If the folded-back pieces 3, 3 and the outer edge of the bottom 6 are inclined, the cardboard can be bent along the corrugated groove when the product is wrapped, so that the folded-back piece can be folded into the outer edge of the body piece. Can not be folded parallel to. Therefore, there is a problem that a gap is created between the folded back pieces 3 and 3 and the lid portions 8 and 8 and the product cannot be assembled while being completely pressed.

Further, the non-sticking portion 5 of the bottom portion 6 is single-layered, and an opening surface of the cardboard appears on the side surface. Therefore, the non-adhesive portion 5 does not have sufficient strength as a cushion, and when it is hung on a string, it may be broken by the tightening force of the string.

The present invention has been made in view of the above situation, solves the above-mentioned problems, is easy to assemble during manufacture and use, and can be bent accurately in accordance with the shape of the product. The present invention provides a prefabricated packaging box that is not damaged.

[0010]

In order to achieve the above object, the present invention has the following constitution. That is, in the assembling type packaging box according to the present invention, the lid portion is continuously provided on both opposite side surfaces of the rectangular bottom portion through the folds, and the sticking pieces are continuously provided on the other opposite both side surfaces through the folds. And a connecting piece having substantially the same size as the rectangular bottom portion and having folded pieces continuously provided on both sides of the cut, and the connecting piece is placed on the bottom portion of the body piece. It is characterized in that both end edges of the continuous piece are adhered, and the pasted piece is folded over the both end edges of the continuous piece and integrally adhered. It is preferable that the cut line of the continuous piece is provided obliquely to the side end. Further, it is preferable that the notch of the continuous piece has a notch formed at a side end portion of the continuous piece and is provided between the notches. By forming a notch,
It is easy to separate the folded piece. Further, as the material, it is preferable to use cardboard for its excellent cushioning property.

BEST MODE FOR CARRYING OUT THE INVENTION The embodiments shown in the drawings will be described in detail below. FIG. 1 is an exploded perspective view of a prefabricated packaging box according to the present invention. The assembling type packaging box 10 includes a body piece 11 and a continuous piece 13 formed by punching a cardboard. The main body piece 11 has a lid portion 19 via folds 17 formed of linear concave portions on opposite sides of a rectangular bottom portion 15,
19 are connected to each other, and the sticking piece 2 is provided on the other opposite sides of the bottom portion 15 with fold lines 20 and 20 formed of linear recesses.
1, 21 are connected in series.

The connecting piece 13 has a rectangular shape having substantially the same size as that of the bottom portion 15, and has a substantially central portion in the groove direction of the corrugated board of the corrugated cardboard and diagonally crossing the groove. That is, a cut line 2 is formed by a perforation or the like diagonal to the side surface.
3 is provided. Both sides of the cut 23 are folded back pieces 13a, 13a, respectively, and both ends of the cut 23 are provided between triangular cutouts 25, 25 formed at the side end portions of the continuous piece 13.

To assemble the continuous piece 13 and the main body piece 11, the continuous piece 13 is placed on the bottom portion 15 and both ends of the continuous piece 13 are attached to the bottom plate 15. The width of the part to be attached is
It is preferable that the width is substantially the same as the width of the sticking piece 21. After sticking both ends of the continuous piece 13 to the bottom plate 15, the sticking piece 21 is folded back from the fold 20 and stuck to the upper surface of the continuous piece 13 (see FIG. 2).

In the continuous installation 13, the folding pieces 13a, 13a are integrally connected through the cuts 23. Therefore, one end surface of the continuous installation piece 13 and the fold 20 of the main body piece 11 should be aligned with each other. Thus, even if it is placed on the other end side, the tip end surface of the connecting piece 13 and the side surface of the main body piece 11 are linear, so that the connecting piece 13 can be attached at an accurate position. As described above, by positioning the one end side, the side end surface of the main body 11 and the side end surface of the continuous piece 13 can be accurately and easily attached in the same direction as a whole.

Next, a method of using the assembling type packaging box having the above structure will be described with reference to FIGS. 3 to 5. First, the continuous piece 13
Is cut from the cut line 23, and the folded pieces 13a, 13a
Start up. Since the continuous piece 13 is only stuck within the range of the sticking piece 21, the folding pieces 13a, 13
a is raised along the inner end surface of the sticking piece 21, and both are raised in parallel.

Then, the folded piece 13a which has been raised,
An article H1 such as a book, which is an unwrapped article, is placed on the bottom portion 15 between the pieces 13a, and the folding pieces 13a and 13a are bent so as to wrap along the edges of the article H1 (see FIG. 4).

After that, as shown in FIG. 5, the lid portion 19 is bent from the fold line 17 to stand up, and further folded so as to wrap a book or the like so that both end portions of the lid portion 19 are overlapped and fixed with the string 27. The release paper of the attaching portion provided on one side of the lid portion 19 in advance may be peeled off and attached and fixed.

In the packaging box having the above structure, since the end faces of the continuous piece and the main body piece are accurately arranged in the same direction, the bending can be performed along the corrugated groove of the corrugated cardboard. This allows for tight packaging without sagging. Also, the folded piece 13
Since a and 13a are fixed by folding the sticking piece 21, the part of the sticking piece 21 has sufficient strength and cushioning property.

Further, the outer edges of the folding pieces 13a, 13a are not easily damaged because the sticking piece 21 is folded and wrapped, while the both ends of the lid portion 19 are overlapped to form a double layer. Therefore, even if the string is wrapped and bound, it will not be damaged by the tightening force of the string.

In the above embodiment, the cut 32 is formed obliquely with respect to the side end surface of the continuous piece 13, but it is formed in the direction perpendicular to the side end surface, that is, in parallel with the corrugated groove of the cardboard. Good. Further, not only cardboard but also suitable cardboard may be used.

[0021]

As is apparent from the above description, the folding piece is not a continuous piece that is integrally connected through the notch, and is integrally attached to the main body piece to form a prefabricated packaging box. Since it is separated from the cut line, it is easy to manufacture and can be attached accurately. Further, since the tip end portion of the folded back piece is wrapped with the sticking piece, the sticking portion with the sticking piece has a multi-layered structure, and sufficient strength and cushioning action can be provided. Therefore, the object to be packaged is not damaged by rough handling.
