Description

[Detailed Description of the Invention] Industrial Application Field The present invention is utilized in the technical field of packaging boxes, particularly wrap round packaging boxes.

Conventional Technology Packaging boxes are generally made of cardboard, and after completing their original mission of storing and distributing the contents, they are dismantled to make them easier to store at retail stores, and then collected by waste paper collection companies. It is considered a valuable resource that can be recycled as a raw material for waste paper.

Therefore, at a retail store or the like, post-processing is required in which all the contents are removed from the packaging box and the packaging box is dismantled for storage or disposal.

Therefore, A-
In the first type of packaging box 60, the sealing tape 61 on the top side is peeled off or cut to open the box and the contents are taken out, but the subsequent post-processing is also done by peeling off the sealing tape 62 on the bottom side. water, by cutting 1
It is easy because it can be disassembled into a single flat plate.

On the other hand, in a wrap-round conventional packaging box 70 as shown in FIGS. 7a and 7b, the perforations 71 to 74 on the top side are cut to open the box and the contents are taken out. Post-processing is extremely difficult because it requires cutting the perforations (not shown) that are made on the bottom side in the same way as perforations 71 to 74 on the top side to open the bottom and then folding it flat. It was time consuming and not easy.

In addition, in another conventional wrap-round packaging box 80 as shown in FIGS. 8a and 8b,
The perforations 81 and 82 on the body are cut to open the box and the contents are taken out. However, for subsequent post-processing, storing the half boxes 80a and 80b, which are divided into upper and lower halves, will be very bulky, and It was not easy to dismantle the half-boxes because it took time and effort.

Furthermore, in still another conventional wrap-round packaging box 90 as shown in FIGS. 9a and 9b, a pair of inner sealing flaps 91 and 92 on one side of the packaging box 90 is provided.
The pair of outer sealing flaps 94 and 95 glued to the box as shown by reference numeral 93 are peeled off to open the box and take out the contents. It is necessary to peel it off from the pair of inner sealing flaps that are glued to it and then fold it flat.
It was very time consuming and not easy.

Moreover, as described above, this packaging box 90 has a pair of outer sealing flaps 94 and 95 on one side and a pair of inner sealing flaps 91 and 92 that are glued together.
Since the box is opened by peeling it off, the opening process is more time-consuming than that of the packaging boxes 70 and 80 shown in Figures 7a-7b and 8a-8b, and the contents are also taken out from the side, which is troublesome. .

In addition, in FIGS. 7a to 9b, 75, 76,
Reference numerals 83, 84, and 96 indicate gluing portions, and wire fixing may be used instead of such gluing, and cut tape may be applied instead of perforations 71-72, 81.

Problems to be Solved by the Invention In view of the prior art described above, the present invention not only facilitates the work of opening the wrap-round packaging box and taking out the contents;
To facilitate post-processing by easily disassembling a box into a single flat plate after taking out the contents.

Means for Solving the Problems The present invention is a wrap round packaging box, in which the upper and lower outer sealing flaps are fixed to the left and right inner sealing flaps at different ends by gluing, etc. In addition to being able to open the box through a separation element such as a zipper placed between the side ends to facilitate opening and removal of the contents, the outer sealing flap is attached to its inner sealing flap after removing the contents. The box can be dismantled into a single flat plate simply by separating the fixed end portions through perforations, making post-processing easier.

Embodiments Next, embodiments of the present invention will be described in detail with reference to FIGS. 1 to 5.

The packaging box 1 according to this embodiment is made of cardboard or the like, and as shown in FIGS. 1 and 2, a connecting portion 3 is provided at the left end of the top section 2, and a left side section 4, a bottom section 5, and a connecting section 3 are arranged at the right end. A right side part 6 is extended, and sealing flaps 7 to 14 are extended from each end of the top part, left and right side parts, and bottom part by half H/2 of the height H of the left and right side parts,
The connection allowance 3 is located outside the upper end of the right side portion 6 with reference numeral 15.
As shown in FIG.
and 13, as indicated by reference numeral 16, and each outer sealing flap 7-10 has an end portion 7a fixed to its inner sealing flap 11-14.
-10a are provided with perforations 17-20 that can be freely divided.

Further, a zipper 21 is provided between both ends of the top surface portion 2 on the side of the connecting portion 3, and an H-shaped cut 22 is provided in the center thereof.

However, the packaging box 1 having such a structure has a third
As shown in the figure, the zipper 21 is opened from the H-shaped cut 22 of the top section 2.

Further, after the box has been opened and the contents have been taken out, as shown in FIG. By dividing from ~10a through perforations 17~20, it is disassembled into a single flat plate.

In this case, it is also possible to fold along these perforations 17-20 without cutting these perforations 17-20.

Note that instead of the zipper 21, two parallel perforations or a cut tape may be provided, and instead of gluing 15 and 16, fixing with a wire fastener may be used, and the connecting portion 3 is attached to the right side portion 6.
It can also be fixed to the upper end surface side.

Fig. 5 shows a modification in which the other ends of the upper and lower outer sealing flaps 7 to 10, which are not glued to the left and right inner sealing flaps 11 to 14, are inserted into the back side of the inner sealing flap to increase the sealing strength. The opening and post-processing are the same as the packaging boxes shown in FIGS. 1 to 4.

Effects of the invention According to the invention, after the box is opened and the contents are taken out, the wrap-round packaging box has perforations 17 to 20 made on the outer sealing flaps 7 to 10.
Since it can be easily disassembled into a single flat plate through the process, post-processing is very easy.

In addition, the top portion 2 can be cut freely via a separation element such as a zipper 21 and can be opened widely, making it easy to open the box and take out the contents.
