Description

[Detailed description of the invention] The present invention relates to a packaging box, in particular, the interior of the box can be partitioned into two chambers without incorporating a separate partition plate, and the partition part is made into a double wall structure to make it strong. Moreover, the present invention aims to provide a completely new packaging box that can be divided into two boxes from this partition portion as necessary.

An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows a developed view of a packaging box according to the present invention.

In FIG. 1, a material 1 such as cardboard or cardboard includes a bottom surface 2, and four side walls 3, 4, 5, 6 extending from the four sides of this bottom surface form a four-sided wall. The bottom part 2 has a perforation 7 placed on the middle line.
The two parts 2a and 2b can be cut as necessary, and one of the opposing first parts
The side walls 3 and 4 of and 2 are also separated by perforations 8 and 9 made on their midline to form parts 3a, 3b and 4.
It can be freely cut into parts a and 4b. On each midline of these side walls 3 and 4 there is also a hole 1
0 and 11 are formed. Further, both ends of these side walls 3 and 4 are extended to form four sleeve pieces 12, 1.
3, 14, and 15 are formed, and slits 16, 17, 18, and 19 are formed at the tip sides of these sleeve pieces, respectively.

Further, the other pair of opposing third and fourth side walls 5 and 6 are extended to form a pair of butt cover plates 20 and 2.
1 is formed, and these lid plates are further extended to form a pair of partition/side wall flaps 22 and 23, and both ends of these partition/side wall flaps are extended to form four folded pieces 24, 25, 26, 27 is formed.

Next, the assembly procedure will be explained with reference to FIGS. 2, 3 and 4.

First, as shown in FIG. 2, from the bottom part 2 of the material 1 shown in FIG.
Fold and stand up 4 and 4.
Fold the two sleeve pieces 12 to 15 so that they are positioned inside the other pair of opposing side walls 5 and 6, and fold the related pairs 12 and 14 and 13 and 15 into their slits 16 and 18 and 17 and 19. Combine through.

Then, as shown in FIG. 3, the side wall 6 is erected, the lid plate 21 is then folded horizontally, and the partition/side wall flap 23 is vertically bent downward to form a perforation along the midline of the bottom portion 2. 7, and fold the folding pieces 26 and 27 along the inner surfaces of the portions 3b and 4b of the side walls 3 and 4. Thereafter, the side wall 5, lid plate 20, partition/side wall flap 22, and folding pieces 24, 25 are assembled in the same manner, and the pair of lid plates 20 and 21 are butted together, and the pair of partition/side wall flaps 22 and 23 are matched against each other. Let them come into contact with you. In this state, the partition/side wall flaps 22 and 23 facing each other are located on the midline (perforation 7) of the bottom part 2, and the four side walls 3 to
The interior of the four-sided wall formed by 6 is partitioned into two chambers. Further, the folding pieces 24 to 27 of these partition-cum-side wall flaps are exposed through holes 10 and 11 formed on the respective midlines of the side walls 3 and 4.

Then, as shown in FIG.
Butt portions of 0 and 21 and holes 10 and 1 of side walls 3 and 4
Partition/side wall flaps 22, 2 exposed from 1
The folding pieces 24 to 27 of No. 3 are fixed together with tape 28 to complete the assembly.

As mentioned above, the packaging box assembled in this way is internally partitioned into two chambers by the two partition/side wall flaps 22 and 23 facing each other, so it is not necessary to separately incorporate a partition plate. Moreover, the double wall structure of the partition makes it very strong and has a good cushioning function, so even if the contents placed in the two chambers are easily damaged, they are sufficiently protected. be able to.

Furthermore, the packaging box assembled in this way can be fitted with its two partition/side wall flaps 22 and 23, if necessary.
It has the great advantage of being able to be separated into two sealed boxes of the same shape. That is, in the packaging box shown in FIG.
(See Figure 2), cut into two equal parts in the longitudinal direction, and cut the bottom part 2 into perforations 7 (second
), the side walls 3 and 4 are divided into parts 3a and 3b and parts 4a and 4b, and the bottom part 2 is divided into parts 2a and 2b.
Closed identical boxes 29a and 29 as shown in the figure.
It can be separated into b.

It should be noted that the perforations 8 and 9 are not necessarily necessary, since the width of the side walls 3 and 4 where these perforations are made is small to form the holes 10 and 11. You can cut it off. Moreover, it goes without saying that cut tape may be attached in place of the perforations 7 inserted in the bottom surface portion 2.
