Description

[Detailed description of the invention] This invention has a cardboard box structure that facilitates storage and disposal by speeding up the opening of the box, making it easier and faster to fold it into a flat state after taking out the contents, and making it possible to reuse it. This relates to punched cardboard for commercial purposes.

As is well known, cardboard boxes are used in all kinds of fields during the product distribution stage, and the amount of cardboard boxes used is increasing year after year.

The reason for this is that it is easier to make compact than containers made of synthetic resin, and there is no risk of causing pollution during processing.

Due to the large amount of cardboard boxes being used, supermarkets and other retail stores are requesting a simpler and faster process for folding cardboard boxes after removing the contents. In some cases, there is also a need for reusability in a folded state.

Assuming that the above requirements can be satisfied,
The bent edges of the bent end plates connected on both sides of the top and bottom panels of the box structure are formed by incision perforations, and a row of incision perforations is provided in the center of the top and bottom panels that reach the respective incision perforations. It consists of a row of holes and cut pieces, and by making cuts along these perforations, the top plate or the top plate and bottom plate are opened and folded flat, and the cut pieces are pasted with tape. There is a well-known packaging box that can be opened on both the upper and lower sides and can be reused.In this case, the bottom plate is also wider than a single row of perforations (note: the width of the cut piece).

) Because it can be cut open, it is difficult to maintain strength by simply attaching tape when reusing it, and in other words, it is not suitable for use as a bottom plate that bears the maximum load.

The present invention was developed by focusing on the diagonal point, which allows for quick opening of the box, quick and simple folding of the box into a flat state, and a sufficient function as a bottom plate for reuse. There are cardboard boxes to provide you with.

Next, an embodiment of the present invention that achieves the above objects will be described in detail with reference to the accompanying drawings.

In Fig. 1, 1 is the top plate, 2 is the left side plate, 3 is the right side plate, and 4 is the bottom plate.At the center of the top plate 1 in the left-right direction, there are two perforated holes 1a with a desired width W. Embossed lines 4a for folding are provided at the left and right centers of the bottom plate 4.

Further, an adhesive piece 5 is connected to one side of the top plate 1.

21 indicates the inner left front plate, 31 indicates the inner right front plate, 22 indicates the inner left rear plate, and 32 indicates the inner right rear plate. The inner right front plate 31 and the inner right rear plate 32 are connected to the right side plate 3 via a fold.

Further, for reasons to be described later, when constructing the box body, the opposing gaps between the inner left front plate 21 and the inner right front plate 31 and between the inner left rear plate 22 and the inner right rear plate 32 are at least 2 times the thickness of the cardboard.
The length of each left and right front and rear plates is 211°221 so that it is more than double.
．． 311 and 321 (that is, each of the above lengths is smaller than the widths IW and 4W of the top plate 1 and the bottom plate 4 by the thickness of the cardboard).

11 is an outer upper front plate, 41 is an outer lower front plate, 12 is an outer upper rear plate, 42 is an outer lower rear plate, and the outer upper front plate 11 and the outer upper rear plate 12 are located before and after the top plate 1. The above-described two perforation holes 1a and the other part leaving a width W between one part are connected through the perforation hole 1mh, and the outer lower front plate 41 and the outer lower rear plate 42 are perforated at the front and rear of the bottom plate 4. They are connected via hole 4mk.

Also, an outer upper front plate 11, an outer upper rear plate 12, an outer lower front plate 41.
Length of outer lower rear plate 42: 111.12 l, 41 l
, 42l is formed by dividing the heights 2h and 3h of the left side plate 2 and right side plate 3.

Furthermore, the outer upper front plate 11 and the outer upper rear plate 12 are provided with perforations 11a, 1 for cutting, which connect with the two perforated holes 1a described above.
2a is provided.

Next, to explain how to use it, for example, in fully automatic assembly line work, after setting a desired article on the bottom plate 4, bend the left side plate 2 and the right side plate 3 (note, respectively) It is bent at the boundary with

Further, all bending of each part will be done at the boundary, but the explanation thereof will be omitted.

) Inner left front plate 21° Inner right front plate 31. Inside left rear plate 22,
The inner right rear plate 32 is bent, and then the outer lower front plate 41 and the outer lower rear plate 42 are bent, and the inner left front plate 21. Lower half of inner right front plate 31, inner left rear plate 22, inner right rear plate 32
The top plate 1 and the adhesive piece 5 are bent and the adhesive piece 5 is attached to the right side plate 3, and then the outer upper front plate 1
1 and the outer upper rear plate 12 and the inner left front plate 21
．． The work is completed by pasting it on the upper part of the inner right front plate 31, the inner left rear plate 22, and the upper half of the inner right rear plate 32.

On the other side of usage, there is so-called manual filling work, but in this case, the inner left front plate 21, the inner right front plate 31, the inner left rear plate 22, the inner right rear plate 32, the outer lower front plate 41 and the outer lower rear The work is performed by gluing and placing the plate 42, then placing the article on the bottom plate 4, bending the top plate 1, attaching the adhesive piece 5, and attaching the outer upper front plate 11 and the outer upper rear plate 12. It ends.

In the box containing the goods configured as described above, there is a space between the inner left front plate 21 and the inner right front plate 31, and between the inner left rear plate 22 and the inner right rear plate 32, which are at least twice the thickness of the cardboard. The above gaps are formed as shown in FIG.

(Note: The gap indicated by the symbol G in the same figure.

) Next, the box opening means will be explained with reference to FIGS. (by pushing in with your index finger or the like), and then holding the cut portion and pulling it along the two perforations 1a, the top plate 1 is divided into left and right halves as shown in FIGS. 8 and 9.

Next, the top plate 1 is separated from the outer upper front plate 11 and the outer upper rear plate 12 using a perforation hole of 1 mh, and the top plate 1, which has been divided into two parts as shown in FIG. 10.11, is opened left and right to take out the article.

When folding after taking out the article, lower front plate 41 outside the bottom plate 4
and the outer lower rear plate 42 along the perforation hole 4mh provided at the boundary, and the bottom plate 4 is cut along the embossed line 4a at the 12th.
13 Fold as shown in Figure 1, and also open the outer upper front plate 11 and the outer lower front plate 4.
1, the outer upper and rear plates 12, and the outer lower and rear plates 42 are also the 12th
．． By folding as shown in Fig. 13, the whole can be made into a flat shape, but in this case, there is a gap G as described above between the inner left front plate 31 and the inner right front plate 31, and between the inner left rear plate 22 and the inner right rear plate 32. This allows these plates to be folded easily and neatly.

(Note: If necessary, instead of folding outward as shown in Figure 12, it may be folded inward.

) In case of reuse, the other cut-off parts except for the cut-off part through the two perforated holes 1a are pasted with duct tape, etc., and the article is placed therein, and then the cut-off part made by the above-mentioned perforation holes 1a is closed with duct tape, etc. However, in this case, since the bottom plate is not cut out like the above-mentioned known ones, it can function well as the original bottom plate.

Since the present invention is constructed as described above, the cardboard box assembled thereby has the perforated holes 11a or 1 for cutting the cardboard box.
By tearing 2a with a fingertip or the like and holding the torn part and pulling it along the two perforation holes 1a, the top plate 1 can be easily and quickly polished for 2 minutes, and then the top plate can be divided into two by cutting out the perforation hole 1mh. 1 can be opened, and it can be easily made flat by cutting out the perforation hole 4mh, but in this case, the inner left front plate 21, the inner right front plate 31, the inner left rear plate 22, the inner right rear plate 32, etc. By forming a gap at least twice the thickness of the cardboard between the opposing sides of the bottom plate 4, it is possible to easily and neatly fold the bottom plate 4 into two.
Since the embossed lines 4a are provided on the bottom plate, the strength of the bottom plate can be maintained well.
