DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembling type packaging box suitable for mailing heavy goods such as books, magazines and the like.

[0002]

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 package is not constant, an assembling type packaging box configured to be folded and packed according to the size of the package is used. For example, in order to mail a product such as a book or a magazine having a constant shape but a different thickness depending on the number of books, a folded piece and a cover that can be freely bent so as to be able to correspond to the size. A prefabricated packaging box having a section is used.

FIG. 6 shows a typical assembly type packaging box conventionally used. On the both sides of the central part of the rectangular main body 1 made of corrugated cardboard, two folded pieces 3 made of corrugated cardboard are provided in a substantially cross shape. The folded pieces 3, 3
The non-adhesive portion 5 having a constant width is provided on the edge side of the main body piece 1 by attaching the edge portion 3a indicated by oblique lines. In the main body piece 1, a portion where the folded piece 3 is adhered is defined as a bottom portion 6, and both protruding end portions are defined as lid portions 8.

[0004] Next, a method of using the assembled packaging box having the above-described configuration will be described. First, in a state where the main body piece 1 and the folded pieces 3 and 3 are opened (FIG. 6), a product H such as a book is placed on the bottom portion 6 while being placed on the edge 3a of the folded piece 3, and then the folded piece 3 Is folded so as to be wrapped around the end of the product H, and both ends are overlapped.

After that, the lid 8 of the main body piece 1 may be folded and wrapped, and the ends may be overlapped and adhered or bound with a string. Since the non-sticking portion 5 protrudes and functions as a cushion for absorbing impact, even a rough handling during mailing does not damage a product such as a book.

[0006]

However, the assembling type packaging box has the following problems. That is, since the folded pieces 3 and 3 are attached to the main body piece 1 respectively, the manufacturing requires many steps such as cutting and attaching,
The production is troublesome, and the cost is increased. In addition, since the folded pieces 3 and 3 are attached to both end edges of the bottom 6 by hand, the inner edges of the folded pieces 3 and 3 and the outer edge of the bottom 6 are attached in parallel. It is difficult to attach them, and they may be attached in an inclined state.

If the folded pieces 3, 3 and the outer edge of the bottom portion 6 are inclined, the cardboard will be bent along the corrugated groove when wrapping the product. Can not be bent in parallel. Accordingly, there is a gap between the folded pieces 3 and 3 and the lids 8 and 8, and there is a problem that the product cannot be assembled in a completely pressed state.

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-adhered portion 5 does not have sufficient strength as a cushion, and may be broken by the tightening force of the string when the string is hooked.

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

[0010]

The present invention has the following configuration to achieve the above object. That is, in the assembling type packaging box according to the present invention, the lid portion is continuously provided on both opposing side surfaces of the rectangular bottom portion via the fold, and the sticking pieces are provided continuously on the other opposing side surfaces via the fold lines. And a continuous piece having substantially the same size as the rectangular bottom and having folded pieces connected to both sides of the cut, and the continuous piece is stacked on the bottom of the main body piece. The present invention is characterized in that both end edges of the continuous piece are adhered, and the adhesive piece is folded on the both end edges of the continuous piece and integrally attached. It is preferable that the cut of the continuous piece is provided obliquely with respect to the side end. It is preferable that the notch of the connecting piece is formed by forming a notch at a side end of the connecting piece and provided between the notches. By forming a notch,
Separation of the folded pieces becomes easy. Further, as the material, it is preferable to be formed of corrugated cardboard because of its excellent cushioning property.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The illustrated embodiment will be described below in detail. FIG. 1 is an exploded perspective view of the assembly type packaging box according to the present invention. The assembling type packaging box 10 includes a main body piece 11 formed by stamping out a cardboard and a continuous piece 13. The main body piece 11 has a lid 19, which is formed on the opposite sides of a rectangular bottom 15 via folds 17, 17 formed of linear concave portions.
19 are continuously provided, and further, on the other opposing sides of the bottom portion 15, the bonding pieces 2
1, 21 are connected in series.

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

In order to assemble the connecting piece 13 and the main body piece 11, the connecting piece 13 is overlapped on the bottom 15, and both ends of the connecting piece 13 are attached to the bottom plate 15. The width of the part to be stuck is
It is preferable that the width is approximately equal to the width of the sticking piece 21. After sticking both end portions of the connecting piece 13 to the bottom plate 15, the sticking piece 21 is folded back from the crease 20 and is attached to the upper surface of the connecting piece 13 (see FIG. 2).

Since the connecting pieces 13 are formed by integrally connecting the folded pieces 13a and 13a through the cuts 23, one end face of the connecting piece 13 and the fold 20 of the main body piece 11 are made to coincide with each other. Accordingly, even if it is placed on the other end side, the distal end surface of the connecting piece 13 and the side surface of the main body piece 11 become linear, so that the connecting piece 13 can be stuck at an accurate position. In this way, by positioning the one end, the side end surface of the main body 11 and the side end surface of the connecting piece 13 can be stuck accurately and easily in the same direction as a whole.

Next, a method of using the assembled packaging box having the above structure will be described with reference to FIGS. First, the connecting piece 13
Is cut off from the cut 23, and the folded pieces 13a, 13a
Start up. Since the continuous piece 13 is only pasted in the range of the pasting piece 21, the folded pieces 13 a, 13
a is raised along the inner end face of the sticking piece 21 and both are raised in parallel.

Next, the turned up piece 13a,
A product H1 such as a book, which is a non-packaged product, is placed on the bottom portion 15 between the portions 13a, and the folded pieces 13a, 13a are folded so as to wrap around the edges of the product H1 (see FIG. 4).

Thereafter, as shown in FIG. 5, the lid 19 is bent from the fold line 17 to stand up, and further folded so as to enclose a book or the like, and both ends of the lid portion 19 are overlapped and fixed with the string 27. Alternatively, the peeling paper of the sticking portion provided in advance on one side of the lid 19 may be peeled off and stuck and fixed.

In the packaging box according to the above configuration, since the end faces of the continuous piece and the main body piece are accurately arranged in the same direction, the folding is performed along the corrugated groove of the corrugated cardboard. Therefore, tight packaging without sagging is possible. 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 folded pieces 13a, 13a are hardly damaged because the sticking pieces 21 are folded and wrapped around, while the both ends of the lid 19 are overlapped and doubled. Therefore, even if the string is wound and bound, it is not damaged by the tightening force of the string.

In the above embodiment, the cut 32 is formed obliquely with respect to the side end face of the connecting piece 13, but is formed in a direction perpendicular to the side end face, that is, in parallel with the corrugated groove of the cardboard. Is also good. In addition, not only cardboard but also appropriate cardboard may be used.

[0021]

As is clear from the above description, the folded piece is a continuous piece integrally connected through a cut, and this is integrally attached to the main body piece to form an assembling type packaging box. Since it is cut off from the cut, it is easy to manufacture and can be accurately adhered. In addition, since the tip of the folded piece is wrapped by the sticking piece, the part to be stuck to the sticking piece has a multilayer structure, and can have sufficient strength and cushioning action. Therefore, the packaged item is not damaged by rough handling.
