DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging box, and more particularly to a packaging box which has a simple assembling means and has a mechanism effective in preventing tampering or unauthorized opening.

[0002]

2. Description of the Related Art Generally, in a packaging box, the box body is formed as a rectangular tubular body, and a lid plate and a bottom plate are connected to the upper and lower ends of a front wall or a rear wall of the tubular body so as to be openable and closable. At the same time, a folding piece to be inserted into the opening of the box body is continuously provided at the ends of the lid plate and the bottom plate.

[0003] It has recently become common to provide a packaging box with the function of preventing unauthorized opening and tampering. However, a box having such a structure is exclusively used as a medicine for human health and life. Are limited to individual packaging boxes,
A cardboard box having such a structure has not been proposed yet.

Further, the tampering prevention mechanism that has been conventionally adopted has been concentrated on the lid plate and the bottom plate portion where tampering is easily performed. It has a double structure and is configured so that the trace of opening can be easily confirmed from the outside if an unauthorized opening operation is performed.

[0005]

However, in the conventional means for preventing unauthorized opening, since the lid plate and the bottom plate portion have the double structure as described above, the structure of the box body becomes complicated, and the product is It has been pointed out that the operation for assembling and the assembling means are complicated, and there are drawbacks such as lack of workability.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an excellent function for preventing unauthorized opening and tampering by simply interposing an inner lid in the opening of a box. It is an object of the present invention to provide a packaging box in which it is possible to easily perform the accommodation operation of the product in the box body, as well as being able to exhibit the above.

[0007]

The present invention comprises a combination of a box body and an inner lid attached to the upper and lower opening surfaces of the box body. The box body is formed in a tubular shape by four front, rear, left and right wall surfaces, and upper and lower side walls The inner lid and the insole are foldably connected to both ends, and the lid plate and the bottom plate are foldably connected to the upper and lower ends of the front and rear side walls, and the boundaries between the inner lid and the insole are bent. The tampering control cover, which is the base end, is formed by punching so that it can be bent freely, and both ends of the cover plate and the bottom plate are formed with fitting notches corresponding to the shape of the tampering control cover. The inner lid is formed in a side-U shape with both ends slightly bent, and a band-shaped adhesive such as double-sided tape is attached to both sides of the inner lid. The box for use is the main point of the invention.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

The packaging box of the present invention comprises a box body 1 and inner lids 2 and 2 which are fitted into the upper and lower openings of the box body.

The box body 1 is formed by folding one sheet of paperboard, and includes a front wall 11, a right side wall 12, a rear wall 13, a left side wall 14,
To form a tubular body by bending it continuously.
Inner lids 16 are provided on the upper and lower ends of the right side wall 12 and on the upper and lower ends of the left side wall 14.
Further, the insole 17 is foldably connected to each other, and the lid plate 18 and the bottom plate 19 are foldably connected to the upper and lower ends of the front wall 11 and the rear wall 13, respectively. Reference numeral 15 is a glue margin that is continuous to the outside of the front wall 11.

Reference numerals 20 and 20 denote tampering restraining lids formed on the inner lid 16 and a part of the insole 17 so as to be freely bendable, and their base ends are in contact with the upper and lower end portions of the right side wall 12 and the left side wall 14, respectively. The inner lid 16 and the insole 17 are punched out so that they can be bent. (See FIGS. 1 and 3)

18 '... 18' and 19 '... 19' are tampering restraining lids 2 formed by notching at the ends of the lid plate 18 and the bottom plate 19.
It is a notch for inserting 0, 20 and has a size such that the tampering restraining lids 20, 20 can be fitted perfectly when the two facing lid plates 18, 18 and the bottom plates 19, 19 are closed. It is cut out.

The inner lid 2 is formed by connecting a few folding pieces 21, 21 to both ends of a paperboard of a size suitable for the opening of the box body 1 so that the side surface has a U-shape. Band-shaped adhesives 3 and 3 such as double-sided adhesive tape are attached to both ends. Release paper (not shown) is attached to the upper surfaces of the band-shaped adhesives 3 and 3.

[0014]

Assembly of the Invention The packaging box of the present invention having the above construction is assembled as follows.

First, a front wall 11, a right side wall 12, a rear wall 13 and a left side wall 14 are sequentially folded along a folding line, and a glue margin 15 is continuously provided at the end of the left side wall 14 at the inner end of the front wall 11. Bonding to form a tubular body.

Next, after the inner bottoms 17, 17 of the bottom portion are bent inward with the tampering restraining lids 20, 20 upright, the inner lids 2 are mounted, and further, both ends of the inner lids 20, 20 are attached. After peeling the release paper of the adhered strip-shaped adhesives 3 and 3, the bottom plates 19 and 19 are folded and brought into contact with the upper surface thereof to close, and further,
Notches 19 'formed by bending the bottom plates 19, 19,
Fold the tampering control cover 20, 20 to the 19 'part,
The back surface is brought into contact with and adhered to the band-shaped adhesives 3, 3.

The closing work of the cover plate part is exactly the same as the above, and after the products are stored in the box body 1 in the state illustrated in FIG. 2, the tampering restraining cover 20, 20 is erected. The inner lids 16 and 16 are bent inward (see FIG. 3), and then the separately formed inner lids 2 are attached so that the upper surfaces of the two inner lids 16 and 16 are closed, and the lid plates 18 and 18 are further attached to the upper surfaces. The assembly is completed by bending and adhering it to the strip-shaped adhesives 3 and 3 and also by adhering the tampering restraining lids 20 and 20.

Although it is not an important technical matter for the present invention, the tampering control lids 20 and 20 are included on the surfaces where the ends of the two lid plates 18 and 18 and the bottom plates 19 and 19 are joined. It is desirable to bond a sealing tape (not shown).

[0019]

As described above, according to the present invention, the inner lids 2 and 2 are attached to the upper and lower openings of the box body 1, and the inner lids 16 and a part of the inner bottom 17 are attached to the upper surfaces of the inner lids 2 and 2. Since the tampering control lids 20 and 20 and the lid plates 18 and 18 and the bottom plates 19 and 19 which are formed to be freely bendable are configured to be bonded to each other, the lid plate 20 portion will be illegally opened with a sharp blade. However, the presence of the inner lid 2 makes it impossible to open. Further, even if an attempt is made to illegally open from the upper and lower end portions of the side wall, it cannot be opened unless the tampering control pressing lids 20 and 20 are cut, and if such an illegal operation is performed, the trace of the unsealing remains clearly. There is a feature that allows you to easily check the fact of fraud.
