Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a tamper-proof carton that can immediately determine whether or not a sealed carton has been opened.

Conventional technology Conventionally, the lid of a carton before sale is sealed by gluing an insert or using a seal, but this can be skillfully peeled off without damaging the carton, and the contents can be taken out and re-sealed. It was possible to seal it.

Problems that the invention aims to solve: The problem with this invention is that once the lid of a carton containing products is opened, a hole is created in the lid that can be seen at a glance that the lid has been opened, and it cannot be resealed. A carton that prevents the lid from being opened was developed for this purpose.

Means for Solving the Problem The configuration of the present invention will be explained according to the above purpose.
In the box body 1 constructed by appropriate side panels,
Flaps 2 are provided on arbitrary both sides of the upper and lower openings A,
A circular half-cut portion 5 is carved on the back surface of the lid plate 4 having the insertion piece 3 provided on the remaining one side, and a slightly larger circular half-cut portion 6 concentrically formed on the surface of the lid plate is also carved,
This is an opening-preventing carton in which a box body 1 is assembled to house a product, and each flap 2 and each lid plate 4 have circular half-cut portions 5 on the back side adhered to each other.

Function The present invention is constructed as described above, and after assembling the box 1 and accommodating the product, each flap 22 is folded and placed in advance with glue in the circular half-cut portion 5 on the back side of each lid plate 4. When the lid plate 4 is opened after being folded and adhered to each other, there is a slightly larger circular half-cut portion 6 carved on the surface of the lid, and a slightly smaller circular half-cut portion 5 formed concentrically on the back surface of the lid. , a crack is generated between each half-cut portion, and a hole is created in the lid plate 4 that cannot be returned to its original state.

Embodiment An embodiment of the present invention will be further explained based on the drawings.As shown in FIG.
Each of the side plates 11, 12, 13, 14 and a glued piece 15 are arranged in series through 0, and the side plates 11 and 13 each have a flap 2 above and below, and furthermore, an insert piece 3 is provided above and below the side plate 12. Each lid plate 4 is provided, and a slightly larger circular half-cut portion 6 is carved on the surface of the lid plate, and a slightly smaller circular half-cut portion 5 is carved concentrically on the back side. Next, as shown in FIG. 2, glue is placed on the glued piece 15, and each side plate 11, 12,
13 and 14 are folded in and adhered with a glued piece 15 to stand up the box body 1.

Furthermore, as shown in FIG. 3, the flaps 2 are each folded, each lid plate 4 is folded over, and a rather small circular half-cut portion 5 carved on the back surface is adhered onto the flap 2.

When the lid plate 4 of the box manufactured in this manner is opened as shown in Fig. 4, a slightly smaller circular semi-cut 5 with glue on the back of the lid and a slightly larger concentric circle on the lid surface are revealed. A crack is generated between the half-cut portion 6 and a hole 16 in the lid plate 4, and the circular piece 17 remains adhered to the flap 2.

FIGS. 5 and 6 are cross-sectional views showing the lid plate 4 and the flap 2 when the lid is closed and opened.

Incidentally, the half-cuts carved on the lid plate can also be made into a polygonal shape other than a circle.

Effects As a result of the present invention configured as in the above embodiment, the following effects are produced.

Once you open the glued and sealed lid,
A ring-shaped torn part appears on the cover plate 4 due to the step between the circular notches 5 and 6, and since it is torn off due to the step, the cover plate 4 is returned and the cover is sealed again. Even if you try to do so, the cutout 17 will not fit neatly into the hole 16 formed in the lid plate 4, so it will be obvious that the package has been opened, and there will be no inconvenience in selling the product, such as having to take out the contents. This is a practical idea for a carton that prevents the lid from being opened.
