BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an unsealing prevention seal and a container using the same.
By attaching the unsealing prevention seal made by coloring the main base material of the seal body so that it is difficult to peel off, the cut surface of the seal can be easily visually checked to know the open / close state of the openable container, preventing the container from being opened. The present invention relates to an anti-opening seal and a container using the same, which significantly improve security.

[0002]

2. Description of the Related Art Conventionally, there are the following containers having the purpose of preventing opening and having security.

That is, in an openable / closable container, a seal is attached to an open / close portion of the container body to enhance security, and the seal must be peeled or cut.

[0004] However, this type of container has the following problems.

That is, the open / closed state of the container is recognized by the seal attached to the open / close portion of the container. If the adhesiveness of the seal is low, the seal is peeled off and then attached again. The container is easily opened.

[0006] Even when the seal is cut and the container is opened, it is difficult to visually recognize the cut surface with a normal seal.

[0007]

As described above, in the conventional openable / closable container, the container can be easily opened,
There is a problem that it is difficult to visually recognize the cut surface of the seal and security is low.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and it is possible to easily visually recognize the cut surface of the seal to know the open / closed state of the openable / closable container and prevent the container from being opened. It is an object of the present invention to provide an unsealing prevention seal capable of significantly improving security and a container using the same.

[0009]

In order to achieve the above object, according to the first aspect of the present invention, the container is bent at a corner of the openable container so as to cover the openable portion of the openable container. Used in a state where the entire surface is firmly adhered in a state where the seal is a colored main base material, peeling protection.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is an external perspective view showing a configuration example of a container with an opening prevention seal according to the present invention. That is, FIG.
As shown in FIG.
The opening prevention seal 3 is stuck to the opening / closing portion of the opening / closing container 2 made of, for example, plastic or paper, that is, at a position where the opening / closing container 2 is prevented from opening and closing.

FIG. 2 is a sectional view showing an example of the configuration of the opening prevention seal 3 according to the present invention. That is, as shown in FIG. 2, the unsealing prevention seal 3 of this embodiment includes a main substrate 4, a peelable protection layer 5, a hologram layer 6, a light reflection layer 7, an adhesive layer 8,
Release paper 9 is sequentially laminated. However, when sticking the opening prevention seal 3 to the openable container 2, the release paper 9 is naturally peeled off.

Here, the main base material 4 is about 50 to 10
A thickness of about 0 μm is appropriate, for example, polyester,
A resin film such as polycarbonate can be used. The main base material 4 has a role of protecting the hologram layer 6 and is colored, for example, by adding a dye, so that the cross section becomes darker than when viewed from the sealing surface, and can be easily recognized. I have. The dye is transferred to a film that is more transparent than the transfer paper by a known technique such as thermal transfer (sublimation transfer). In this case, in the case of sublimation transfer, the dye enters the inside of the film. Furthermore, as transfer paper,
It is desirable to use a relatively light color of the same color over the entire surface.

As the peelable protective layer 5, for example, an acrylic resin, a mixture of an acrylic resin and a vinyl resin is formed into a paint, and a solvent coat method such as a bar coat, a blade coat, an air knife coat, a gravure coat roll coat, or the like is used. Alternatively, by applying by a known coating method such as a screen printing method and drying, a thickness of 1 to 2
A resin layer of about μm is formed.

On the other hand, the embossed relief hologram layer 6 is formed, for example, by coating an acrylic resin, a urethane resin, a cellulose acetate resin, a nitrocellulose resin or the like with a paint and by the same coating method as described above. The thickness is preferably about 0.5 to 2 μm, and the hologram layer 6 is formed by heating and pressing a nickel press plate on which a hologram image is formed with respect to this resin layer.

The light reflecting layer 7 is preferably made of a metal having a high surface reflectance. For example, a metal such as aluminum or tin can be formed by a vacuum deposition method, a sputtering method, an ion plating method, or the like. The thickness is preferably about 300 to 1000 angstroms.

Further, the adhesive layer 8 is mainly composed of, for example, an acrylic resin or a vinyl resin, and has a thickness of about 0.5 to 2 μm by the above-mentioned coating method. The adhesive layer 8 has an adhesive strength stronger than that of the peelable protective layer 5.

Next, a method of using the container 1 with the opening prevention seal of the present embodiment configured as described above will be described with reference to FIGS.

First, the opening prevention seal 3 is bent so as to cover the opening / closing portion of the openable / closable container 2 to form a corner (edge portion).
Paste in.

On the other hand, in order to open the openable container 2 having the opening prevention seal 3 attached to the opening portion,
The only way to do this is to peel off or cut off the opening prevention seal 3.

However, in this case, it is difficult to peel off the anti-opening seal 3 because the adhesive layer 8 of the anti-opening seal 3 uses a highly adhesive adhesive. That is, if the forcible opening prevention seal 3 is forcibly peeled off, the adhesive of the adhesive layer 8 has a stronger adhesive strength than the adhesive strength of the peelable protective layer 5. Alternatively, separation occurs between the hologram layer 6 and the light reflection layer 7. At this time, the hologram layer 6 and the light reflection layer 7 are broken because a part of the hologram layer 6 and a part of the light reflection layer 7 are separated and adhered to the peelable protective layer 5. You.

Accordingly, the opening prevention seal 3 must be cut to open the opening / closing portion. FIG. 3 is a perspective view showing a state in which the opening prevention seal 3 is cut and the opening / closing portion is opened. That is, the cut surface of the main substrate 4 becomes darker due to the dye contained therein than when viewed from the surface, and the cut surface is easily visible. In this case, even if the opening prevention seal 3 is carefully cut, the hologram layer 6 and the light reflection layer 7 are very thin and thus easily broken.

On the other hand, even if the cut surface is adhered for opening again after the opening / closing portion of the opening / closing container 2 is opened, as can be seen from the above, the hologram layer 6 and the light reflection layer 7 are broken. You can easily find the cut surface.

As shown in FIG. 4 as an enlarged perspective view,
By using a film of about 50 to 100 μm for the main base material 4 (there is a certain elasticity,
It is very difficult to glue the cut surface back to its original condition. That is, since the opening prevention seal 3 is once cut, the cross section of the cut surface is visible.

That is, the container has extremely high security.

As described above, the container 1 with an opening prevention seal according to the present embodiment has a colored main substrate 4, a peelable protective layer 5, a hologram layer 6, a light reflection layer 7, an unsealing prevention seal 3 in which an adhesive layer 8 having an adhesive strength stronger than that of the peelable protective layer 5 and a release paper 9 are laminated in this order.

Therefore, when the openable container 2 is opened and closed, the openable container 2 is attached to the openable portion.
Since the main base material 4 is colored, the cut surface can be easily visually recognized when the unsealing prevention seal 3 is cut.

Thus, the open / close state of the openable container 2 can be easily known, and even if the openable container 2 is opened, it can be immediately detected. Security can be significantly improved.

The present invention is not limited to the above embodiment, but can be implemented as follows.

In the above embodiment, the unsealing prevention seal 3 has a stronger adhesion than the colored main substrate 4, the peelable protective layer 5, the hologram layer 6, the light reflecting layer 7, and the peelable protective layer 5. Although the case where the adhesive layer 8 having a force and the release paper 9 are sequentially laminated has been described, it is needless to say that the present invention is not limited to this.

[0034]

According to the present invention, as described above, the colored main base material and the peeling property are provided on the open / close portion of the openable / closable container body .
Protective layer, hologram layer, light reflecting layer,
Adhesive layer with adhesive strength stronger than adhesive strength, release paper
The next layer of the anti-sealing seal is firmly attached, so the cut surface of the seal can be easily visually checked to determine the open / closed state of the openable container, preventing the container from being opened and ensuring security. An anti-sealing seal and a container using the same that can be significantly enhanced can be provided.
