Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a packaging box having a function of preventing tampering with a packaged product by leaving a trace of opening.
[0002]
[Prior art]
Conventionally, as a box for packaging roll paper for a printer, as shown in FIG. 9, a pair of side walls 51 and end walls 52 form a peripheral wall, and a lid flap 53 extending from the upper edge of both side walls 51 A cover plate 54 extending from the upper edge of the end wall 52 is overlapped, and a sticking plate 55 extending from the tip thereof is attached to the outer surface of the other end wall 52 with a hot melt adhesive and sealed. ing.
[0003]
In this packaging box, a zipper 57 is provided on the base end side of the bonding portion 56 of the sticking plate 55. Since the zipper 57 cannot be opened unless the zipper 57 is cut, for example, a regular product is replaced with a poor product and resealed. Even so, there will always be traces of opening, preventing such crimes.
[0004]
[Problems to be solved by the invention]
However, in the packaging box as described above, there is a problem in that the packaging work efficiency is reduced due to sealing with a hot-melt adhesive when packaging the product, and the cost required for the operation of the material and the sealing machine is increased.
[0005]
Then, this invention makes it a subject to provide the packaging box which can be sealed easily without using an adhesive agent and can leave the trace of opening and can prevent mischief to goods.
[0006]
[Means for Solving the Problems]
In order to solve the above problems, the packaging box according to the present invention is provided with a folded piece on the insertion plate of the cover plate, folded the folded piece outwardly, and engaged with a cutout portion formed on the opposed inner folded plate. In addition, a notch with a connecting portion was made in the end wall to form a pushing piece that coincided with the notched portion, and a notch with a connecting portion was made in the base end of the lid flap.
[0007]
In this packaging box, when the pushing piece is pushed in and opened, the connection part of the notch is cut, and if the lid plate is forcibly pulled up and opened without pushing in the pushing piece, the base flap of the lid flap is connected. The part is cut, and in any case, a trace remains.
[0008]
In addition, if a guide ruled line is put on the back of the lid plate, if the lid plate is forcibly pulled up and opened without pushing the pushing piece, the lid plate will bend along the guide ruled line, and an abnormality will be found. It becomes easy.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the accompanying drawings.
[0010]
In this packaging box blank, as shown in FIG. 1, each pair of side walls 1 and end walls 2 are alternately arranged, and lid flaps 3 are provided on the upper edges of both side walls 1. A lid plate 4 is connected to the edge, and an inner folded plate 5 is connected to the upper edge of the other end wall 2. A bottom flap 6 is connected to the lower edges of the side walls 1, and a bottom plate 7 is connected to the lower edges of the both end walls 2.
[0011]
A passage 8 is provided at the outer edge of the other end wall 2, an insertion plate 9 is connected to the tip of the cover plate 4, and a folded piece 10 is provided at one end of the insertion plate 9. . A cutout portion 11 is provided on one side of the inner folding plate 5, and a zipper-shaped cut 13 with a connecting portion is placed on one side upper portion of the end wall 2, so that a pushing piece symmetrical to the cutout portion 11 is formed. 12 is formed.
[0012]
In addition, on the back surface of the cover plate 4, guide ruled lines 14 are placed at the four corners and the middle part, and a connecting part is provided at the base end of the cover flap 3 extending from the side wall 1 located on the opposite side of the passage 8. Zipper-shaped notch 15 is inserted.
[0013]
In order to assemble the blank and wrap the product, as shown in FIG. 2, each pair of side walls 1 and end walls 2 is bent into a rectangular tube shape, and the passage 8 is attached to the opposite side wall 1 to form a peripheral wall. Then, the bottom flap 6 and the bottom plate 7 are bonded together, the opposing bottom plates 7 are engaged with each other, and the bottom surface is closed.
[0014]
Then, as shown in FIG. 3, the inner folded plate 5 is folded on the back surface of the end wall 2, the folded piece 10 is folded outward to close the lid plate 4, and the insertion plate 9 is connected to the lid flap 3 and the inner folded plate. 5, the folded piece 10 is fitted into and engaged with the cutout portion 11 by repulsion, and the lid plate 4 is locked.
[0015]
Thus, in the said packaging box, since it can seal without using an adhesive agent by engagement with the folding piece 10 and the cutout part 11, goods can be packaged efficiently and packaging cost can be reduced.
[0016]
On the other hand, when opening the packaging box, as shown in FIG. 4 and FIG. 5, the connecting portion of the notch 13 is cut and the pushing piece 12 is pushed in, the folding piece 10 is pushed by the pushing piece 12, and the folded piece 10 and the cutout part 11 are disengaged, and the cover plate 4 is opened as shown in FIG.
[0017]
When opened in this way, even if the product is replaced and resealed, there remains a trace of the cut portion 13 being cut, so there is a high possibility that fraud will be revealed during inspection, and tampering with the product is prevented. Can do.
[0018]
Further, as shown in FIGS. 7 and 8, when the cover plate 4 is forcibly pulled up and opened without pushing the pushing piece 12, the cover plate 4 is bent along the guide ruled line 14, and the cover flap 3 Since the connection portion of the cut 15 is cut, an abnormality can be easily found.
[0019]
【The invention's effect】
As described above, in the packaging box according to the present invention, it is possible to seal without using an adhesive due to the engagement between the folded piece and the cutout part, and when the pushing piece is pushed in and opened, the connection part of the cut is cut. If the lid plate is forcibly pulled up and opened without pushing the pushing piece, the base end notch connecting portion of the lid flap is cut.
[0020]
In this way, in any case, since traces remain, fraud can be found from the appearance at the time of inspection, tampering with products can be prevented, and safety in the distribution process can be ensured.
[0021]
Also, if a guide ruled line is put on the back side of the cover plate, the cover plate will be bent along the guide ruled line when the cover plate is forcibly pulled up and opened without pushing in the pushing piece, so it is easy to make abnormalities. Can be found.
