JP-A-2005-8269

In the packaging box of Patent Document 1, when the upper projecting piece adhered to the outer surface of the lid is peeled off, the release agent layer provided on the projecting piece adhesive portion of the lid is peeled off together with the adhesive layer. Therefore, when the upper projecting piece is peeled off due to mischief without being able to be re-adhered, the upper projecting piece remains peeled off and the peeled state can be visually confirmed.

With such a configuration, the requirements for tampering prevention are fully satisfied. However,
In the packaging box of Patent Document 1, the upper projecting piece appears on the outside of the lid. For this reason, the appearance is impaired, and the packaging box for cosmetics and other products for which appearance is important is not sufficiently met with expectations, leaving room for improvement.

Therefore, it is an object of the present invention to realize and provide a packaging box in which a falsification prevention function is provided without impairing the appearance.

In order to solve the above problems, in the present invention, the falsification prevention packaging box is configured as follows.
That is, the four side walls constituting the square cylinder, the upper lid that closes the upper opening of the square cylinder, the bottom lid that closes the lower opening so that it cannot be resealed, and a pair of facing inner flaps that are folded inside the upper lid. An insertion piece connected to one side of the upper lid via a crease line and a pressing flap that is folded inside the inner flap are provided.
The upper lid is connected to the upper end of the side wall at a position adjacent to the side wall to which the pair of inner flaps are connected via a crease line, and further, the upper lid has a breaking line for separating the insertion piece.
The pressing flap is connected to the upper end of the side wall at a position facing the side wall to which the upper lid is continuously provided via a crease line.
The insertion piece is folded back along the crease line and inserted between the inner flap and the pressing flap.
The pressing flap is pushed up from the lower opening to an article housed inside the box, and the insertion piece is sandwiched between the pressing flap and the inner flap.

In this tamper-proof packaging box, the upper lid is closed first, and then the insertion piece connected to one side of the upper lid is bent along the crease line under the condition that the pressing flap hangs down inside the box. Insert it between the flap and the pressing flap.
After that, the article to be stored is stored inside the box through the lower opening, and the article is pressed down to push up the flap from below.

Then, after that, the lower opening is closed by the bottom lid. The bottom lid makes resealing impossible, such as by gluing.

This tamper-proof packaging box has notches at both ends of the crease line between the upper lid and the insertion piece, and is further located on the root side of the pressing flap in the assembled state of the pair of inner flap boxes. A protrusion may be provided on the edge so that when the insertion piece is inserted between the pressing flap and the inner flap, the protrusion is inserted into and engaged with the notch.

The bottom lid that cannot be resealed has a pair of facing inner flaps that are folded inside the bottom lid and a crease at the lower end of the side wall at a position facing the side wall in which the bottom lid is continuously provided. A structure including a connecting flap that is continuously connected via a wire, the connecting flap is folded outside the pair of inner flaps, the bottom lid is overlapped on the connecting flap, and the bottom lid is adhered to the connecting flap. Although good in appearance and preferred, the sealing of the lower opening of the box is not limited to its structure.

The insertion piece provided at the tip of the lid is bent and inserted into the inside of the lid, and the lock piece provided on the insertion piece is locked to the inner flap folded inside the lid to insert the insertion piece. Several methods have been proposed so far, such as a box sealing structure that prevents the box from coming off from the position, and even with such a sealing structure, it is possible to make it impossible to reseal the bottom lid.

In the falsification prevention packaging box of the present invention, when the pressing flap is pushed up from below by an article to be stored, the insertion piece inserted between the pressing flap and the inner flap is pushed by the pressing flap and is parallel to the upper lid. It is bent until it is in a close state, and is sandwiched between the pressing flap and the inner flap at the pushing end point (the storage completion point of the article) of the pressing flap by the article.

In this state, the upper lid prevents the insertion piece from being pulled out from the insertion position. Therefore, in order to open the upper lid, it is necessary to separate the insertion piece from the upper lid along the breaking line, which prevents the upper opening from being resealed by the upper lid, and prevents mischief from opening and tampering. To.

The tamper-proof packaging box of the present invention has a simple structure and is easy to assemble, and there are no protrusions to be attached to the surface of the upper lid, so that it can be used without problems for packaging products for which appearance is important. It will be a nice looking box.

It is a perspective view which shows the 1st process (bending process of a pressing flap) of the upper lid sealing of a box. It is a perspective view which shows the 2nd process (the process of bending an inner flap) of sealing the upper lid of a box. FIG. 5 is a cross-sectional view showing a state in which the top lid is closed, the insertion piece is pressed in, and the insertion piece is inserted between the flap and the inner flap. FIG. 5 is a cross-sectional view of a main part showing a state in which the pressing flap is pushed up by an article to be stored (a state in which the upper lid is sealed) after the insertion piece is inserted along the VI-VI line of FIG. It is sectional drawing which shows the state which separated the insertion piece from the upper lid along the breaking line provided on the upper lid. It is a perspective view which shows the state which the insertion piece was separated from the upper lid along the break line, and the inner flap was opened.

Hereinafter, embodiments of the falsification-preventing packaging box of the present invention will be described with reference to FIGS. 1 to 8 of the attached drawings.

As shown in FIGS. 1 and 2, the example tamper-proof packaging box 1 includes side walls 2 to 5 on four surfaces constituting a square cylinder, a glue margin 6 connected to one side edge of the side wall 5, and the above. The upper lid 7 that closes the upper opening of the square tube and
An insertion piece 9 connected to the tip of the upper lid 7 via a crease line 8, a breaking line 10 provided in the middle of the upper lid 7 for separating the insertion piece 9 from the upper lid 7, and inside the upper lid 7. It has a pair of facing inner flaps 11 and 11 to be folded, and a pressing flap 12 connected to the side wall 5.

The upper lid 7 is connected to the upper end of the side wall 2 via the crease line 13, and the pair of inner flaps 11 and 11 are connected to the upper ends of the side walls 3 and 4 arranged to face each other via the crease line 14 and 14. Further, the pressing flap 12 is continuously provided at the upper end of the side wall 5 facing the side wall 2 via the crease line 15.

In the example packaging box, the lower opening of the square tube, which is composed of four side walls, is sealed by the bottom lid 16, a pair of facing inner flaps 17, 17 folded inside the bottom lid 16, and a pair of the bottom lid 16. It is made by a connecting flap 18 that is folded between the inner flap 17 and the bottom lid 16.

The bottom lid 16 is connected to the lower end of the side wall 2 via the crease line 19, the inner flaps 17 and 17 are connected to the lower ends of the side walls 3 and 4 via the crease line 20, and the connecting flap 18 is further connected. It is continuously provided at the lower end of the side wall 5 via the crease line 21.

In the example tamper-proof packaging box 1, notches 22 are formed at both ends of the crease line 8, and further, in the assembled state of the pair of inner flaps 11 and 11, the edges located on the root side of the pressing flap 12 The projecting pieces 23 and 23 are provided.

24 in FIG. 2 is a crease line between the side walls 2, 3, 4, and 5, and 25 is a crease line between the side wall 5 and the glue margin 6.

In the example falsification prevention packaging box 1 composed of the above elements, the glue margin 6 is glued to one side edge of the side wall 3 to form a square cylinder having four surfaces.

Then, as shown in FIG. 3, the pressing flap 12 is bent inward along the crease line 15, and then the pair of inner flaps 11 and 11 are bent inward along the crease line 14 as shown in FIG.

Then, as shown in FIG. 5, the upper lid 7 is bent along the crease line 13 and overlapped on the inner flap 11, and the insertion piece 9 is further bent along the crease line 8 to be pressed into the flap 12 and inside. Insert it between the flap 11 and the flap 11.

At the time of this insertion, the pressing flap 12 is in a state where the tip side (free end side) is allowed to hang down, so that it is pushed by the insertion piece 9 and escapes in the direction in which the tip end side hangs down significantly, whereby the insertion is performed. The insertion of the piece 9 proceeds without any trouble.

After completing the above work, the article A to be stored is inserted into the inside of the box through the unsealed lower opening as shown in FIG. Then, the pressing flap 12 is pushed up from below by the article A. Article A is stored in a size capable of maintaining the pushed-up state.

After storing the article A, the lower pair of inner flaps 17, 17 are bent inward along the crease line 20, then the connecting flap 18 is bent along the crease line 21 and stacked on the inner flap 17, and then The bottom lid 16 is bent along the crease line 19 and superposed on the connecting flap 18, and the inner surface of the bottom lid 16 is adhered to the connecting flap 18 to complete the assembly of the box and the storage of the article A.

In the state of FIG. 6, the insertion piece 9 is sandwiched between the pressing flap 12 and the inner flap 11, and the upper lid 7 prevents the insertion piece 9 from being pulled out from the insertion position.

In the illustrated storage box, in the assembled and stored state, the projecting piece 23 fits into the notch 22 and engages with the storage box, so that the upper lid 7 is prevented from being pulled out while being bent.

Therefore, when opening the upper lid 7, as shown in FIGS. 7 and 8, the insertion piece 9 is separated from the upper lid 7 along the breaking line 10. As a result, the upper lid 7 cannot reseal the upper opening. Therefore, opening and tampering by mischief are prevented.

As for the sealing of the lower opening of the box, the structure described in the embodiment is preferable because it looks good and is easy to assemble. However, as described above, there have been several sealing structures that prevent the lid from being resealed. The lower seal of the box, which is known and less noticeable than the upper one, may employ a known structure.
