Description

[Detailed explanation of the invention] [Industrial application field] This invention relates to an assembly box, and more specifically, the body box and the lid box are integrated, and when the lid box can be overturned by the body box, it becomes locked. This is about an assembly box that gets old.

[Prior art] This type of box is conventionally used, for example, in the 1980s.
The one shown in Japanese Patent No. 175416 is well known.

In this conventional technology, a box consisting of a bottom plate, a connecting plate, a lid plate, an inner and outer plate, an end plate, etc. is provided with a bendable locking piece protruding from the center of the side wall of the box with the bottom plate at the center, and a lid This box has a recess formed by a hole in the center of the inner wall of the lid centered on a plate, and a bendable tongue piece is provided on the back surface corresponding to the recess.

That is, in this case, the lid can be locked by bringing the outer edge of a locking piece b, which is bendably protruded from the center of the side wall of the body box, into contact with the inner edge of a hole c formed in the center of the inner wall of the lid box. (retention).

By pushing the tongue piece d inside the hole c, the locking piece b comes off from the edge of the hole c, and the box can be opened easily.

[Problem to be solved by the invention] Therefore, the above-mentioned conventional technology has the big problem of not being able to prevent crimes such as intentionally changing the products in the box, and in particular, crimes such as so-called pleasure crimes such as putting poisonous substances into the food in the box. There is a point.

[Purpose of the invention] The purpose of this invention is to eliminate the above-mentioned drawbacks, by cutting and raising protruding pieces on the body box and lid box that engage with each other when the lid is opened, and by locking the protruding pieces together. To provide an assembly box which cannot be opened and whose opened state can be easily determined by the bending of a protruding piece once the lid is opened.

[Summary of the invention] In order to achieve the above object, the assembly box of this invention centers on an end plate in which insert plates are connected in the width direction through the folds, and each of the end plates is connected through the folds. A bottom plate and a top plate in which a side plate, a folding plate, and a contact piece are connected in the direction in which the insertion plate is connected through folds on both sides, and a folding piece having diagonal folds is connected in the direction in which the insertion plate is connected. The end plate, folding plate and contact piece connected through the fold are connected in order through the fold to integrate the body cover forming part, the side plate and end plate around the bottom plate are folded inward, and the side plate and the end plate around the bottom plate are folded inward and the The folded piece folded in half is attached to the inside of the side plate, the folded plate is folded inward, and the contact piece at the end is brought into contact with the inner surface of the bottom plate to form a body box, and the side plate around the top plate is Then, fold the end plate inward, attach the insert plate and the folded piece folded outward in half to the inside of the side plate, fold the folded plate inward, and attach the contact piece at the end to the inner surface of the top plate. A locking piece cut and raised from the end face plate on the bottom plate side and a locking piece cut and raised on the folded plate on the top plate side are configured to lock when the lid is closed.

[Embodiment of the invention] As shown in FIG. 1, the assembly box of this invention has an insert of the same length as the connecting length of the side plate, folding plate, and contact piece, which will be described later, in the width direction through the fold 25. Board 2
Folds 26,
Folds 28 to 3 are formed in the connecting direction of the insert plate through 27.
A bottom plate 3 and a top plate 4 in which side plates 5, 8, folding plates 6, 9, and contact pieces 7, 10 are connected in order through 0, 31 to 33, and a folding plate with diagonal folds 34, 35. an end plate 11 in which the pieces 13 and 14 are connected in the insertion plate connecting direction via folds 36 and 37 and also between the side plates 5 and 8 via folds 38 and 39;
12, folding plates 15, 16 and contact plates 17, 1
8 are sequentially connected through folds 40 to 42 and 43 to 45, and the end plate 11 and the folded plate 1
U-shaped cuts 19, 20 with folds 41, 44 and side folds 46, 47 are provided at 6 to provide locking pieces 21, 22 to form a material 48 that integrates the body and lid forming portions 23, 24. It is then assembled as described below.

As shown in FIGS. 2a to 2c, the assembly box A of this invention has a bottom plate 3 of a body box forming part 23, a side plate 5,
Fold the end plates 1 and 11 inward, and fold the folded pieces 13 and 14 in half outward at the fold line 34 so that the folded pieces 13 and 14 are folded in half to the inner side of the side plate 5 at the fold lines 36 and 38. Folding plates 6, 15 are attached to each other.
The contact pieces 7 and 17 which are bent outward at the folds 6 and 41 and the folds 30 and 42 are folded back so that they are in surface contact with the bottom plate 3, and the folded pieces 13 are sandwiched between the side plate 5 and the folded plate 6. to form a shape-retaining body box 49, and then a second
As shown in Figures d and e, the side plate 8 and end plate 12 are bent inward at folds 31 and 43 with respect to the top plate 4, and the insert plate 2 bent inward at fold 25 is attached to the end plate 12. Fold this folded piece 14 inward at the fold 35.
Fold it in half outward at creases 37 and 39.
The contact pieces 10, 1 are made by bending the folding plates 9, 16 outward at the fold lines 32, 44 and the fold lines 33, 45 so as to attach them to the inside of the side plate 8 together with the insertion plate 2.
8 is folded back so that it is in surface contact with the top plate 4, and the insertion plate 2 and the folding plate 14 are sandwiched between the side plate 8 and the folding plate 9 to maintain their shape, and the lid box is slightly larger than the body box. Assemble 50 pieces each.

[Function of the invention] The assembly box A with an integrated body and lid of this invention is constructed as described above, and the body box 49 has a fold 27 as shown in FIG.
When the lid box 50 connected as a hinge can be overturned, the locking piece 21 cut and raised on the end plate 11 of the body box 49
and a locking piece 22 cut and raised on the folding plate 16 of the lid box 50.
When the lid box 50 is folded outward and inward at 30 to 40 degrees at the folds 46 and 47, and the lid box 50 is placed over the body box 49 as shown in FIG. It comes into contact with the end plate 11 and is returned again in the opposite direction to the bending direction, but for folding purposes, as shown in FIG. When the lid box is pushed in the direction shown by the arrow, the locking pieces 21 and 22 are cut and raised in the opposite direction in the final fitted state as shown in Fig. 4c.
will get stuck inside each other and become locked, making it impossible to open the lid.

In order to open the lid of the assembly box A, the lid can be opened by forcibly pulling the locking pieces 21 and 22 so that either of them is folded back at the folds 46 and 47. However, in this case, the locking pieces 21, 2
2 is folded back, so even if the lid box is closed again, it cannot be expected that it will be in the locked state before opening again, and it is easy to identify that the lid has been opened. This locking piece 2
By locking 1 and 22, there is no need for sealing, which saves time and effort for packaging.

[Effects of the invention] As described above, in this invention, the folding plate 16 on the top plate 4 side is partially cut and raised inside the locking piece 21 which is partially cut and raised on the end plate 11 on the bottom plate 3 side. Since the locking piece 22 is inserted to lock the closed state of the lid, once the lid is closed, the lid cannot be opened unless either the locking piece 21 or 22 is broken.
Even if the lid is forcibly opened, it will be immediately obvious that the lid has been opened, so there is a risk of the purchaser opening the lid without permission, intentionally changing the contents, contaminating foreign objects, and especially so-called happy criminals who put poisonous substances into the food inside the box. This has the effect of reliably preventing
