Description

[Detailed Description of the Invention] This invention relates to a packaging box used for transporting articles such as electronic parts and electrical appliances.

Relatively small electronic components such as TV tuners and printed wiring boards are generally transported continuously and in large quantities between factories or within a factory, but in this case, a certain number of components are stored in one carton and transported. Packaging boxes are often used.

By the way, the requirements for such packaging boxes are as follows:
In addition to being low-priced, the packaging material has great strength;
The packaging process is easy, and the number of storage members required to neatly store items in the carton is small.

In particular, when a packaging box is used as a so-called joint, its strength and ease of packaging work are important matters for ensuring reliable transport and transportation of articles, reducing distribution costs, and improving efficiency.

However, most of the conventional packaging boxes do not have sufficient strength and require a large number of article storage members for packaging, making the packaging operation complicated.

FIG. 1 shows a perspective view of an article storage member as an example used in a conventional packaging box, and FIG. 2A-9 shows a plan view of its parts.

As is clear from these figures, in order to form m article storage sections A, three and six parts 1 and 2 are required, respectively.

In addition, in order to assemble the storage member 3, cut out the notch 4 of each part.
This is done by mating 5 and 5, but the mating work is 6
Therefore, it takes a very long time just to assemble several tens of units of packaging boxes.

Furthermore, this storage member 3 has a disadvantage in that fin pieces 6 and 7 are formed around the periphery, and these fin pieces are easily broken.

There are several conventional article storage members in addition to those shown above, but none of them have been sufficiently improved in terms of reduction in the number of parts, workability, and strength.

Therefore, conventional packaging boxes have disadvantages such as having to be disposed of after being used only a few times as their strength decreases, or requiring a long time for packaging, which significantly reduces the efficiency of transporting goods. It was hot.

This idea was developed in consideration of the above points, including strength,
The object of the present invention is to provide a packaging box with improved workability, low cost, and a small number of parts.

Examples of this invention will be described below with reference to the drawings.

Figure 3 is a plan view of the seat for assembling the article storage member;
The figure shows a partially cutaway perspective view of the article storage member assembled from the sheet, and FIG. 5 shows an assembled view of the article storage member storing articles and the carton.

As is clear from these figures, the article storage member 3' is formed by cutting and folding a single sheet.

In FIG. 3, 8 is a folded part formed parallel to the side 9 of the sheet, 10.10' is formed between adjacent folded parts 8, and in the center between the folded part 8 and the side 9. A 0-shaped notch parallel to the side 9, 11° 11' is the notch 10.1
This is a bend that continues to 0'.

Note that the upper bent portion 11.11 of the bent portion 11.11'
' is formed between both ends of the upper horizontal cut part of the upper cut part 10 and the upper side of the sheet, and the lower bent part 11.11' is formed between the lower cut part 10 and the upper side of the sheet.
0' is formed between both ends of the lower horizontal notch and the lower edge of the sheet, and the central bent part 11, 11' is formed between both ends of the lower horizontal notch of the upper notch 10 and the lower notch 10'. It is formed between the upper horizontal notches.

After the bent portions 8, 11, 11' and the cut portions 10.degree. and 10' are formed as described above, the structure is assembled as shown in FIG.

That is, the partition plate 12 of the article is constructed by bending the folded portion 8, and the protruding pieces 13, 13' that support the storage member itself through the notches 10.10' are formed by folding the folded portion 11.
11', an article storage section A having a width d is formed between the partition plates 12.

Therefore, articles 14 can be stored between the partition plates 12, and these articles 14 are held in the center of the carton 15 by the protruding pieces 13.

In addition, in this case, the cut portions 10, 10' and the bent portion 11.1
1' and stops 16, 17, 18 are formed at the same time, so that two articles 14 can be accommodated between each partition plate 12 with external buffers at both ends.

That is, between stoppers 16.17 and 17.1.
Items 14 can be stored between the spaces 16 and 17, and each item has stoppers 16, 17 or 17 at both ends.
Protected by 18.

In short, in this storage member 3', ten articles 14 can be individually connected and stored by the partition plate 12 and the stoppers 16, 17, 18, and can be held in the center of the carton 15.

Incidentally, since the sheet with the cut portions and folded portions shown in FIG. All you have to do is fold the sheet.

As described above, according to this invention, the article storage section is formed by simply folding a single sheet, so the work efficiency is very good, and the number of parts is only a carton and one sheet, so it is easy to manage. It also has the advantage of being low cost.

Furthermore, the stopper that protects the article from external forces is strong because it is not fin-like, and therefore has the advantage of increasing the strength of the storage member and significantly extending its service life.
