The present invention relates to an anti-opening seal, which enables the user to know the open / closed state of a releasable container by easily visually observing the cut surface and prevents the unsealing of the container to remarkably improve security, and a container using the same.

[0002]

[Prior art]

 Conventionally, as a container having security for the purpose of preventing opening, there are the followings, for example.

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

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. However, if the adhesive property of the seal is low, the seal is peeled off and then attached again, The container is easily opened.

Further, 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]

[Problems to be solved by the device]

 As described above, in the conventional open-close type container, it is difficult to open the container easily, and it is difficult to visually recognize the cut surface of the seal, and there is a problem that the security is low.

The present invention has been made to solve the above-mentioned problems, and it is possible to easily see the cut surface of the seal to know the open / closed state of the openable container and prevent the container from being opened. It is an object of the present invention to provide a tamper-proof seal capable of significantly improving security and a container using the seal.

[0009]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, first, in the device according to the first aspect of the invention, in the seal firmly attached to the open / close portion of the open / close container, the main base material of the seal body is colored.

Here, in particular, the seal body is an adhesive layer having an adhesive force stronger than that of the colored main substrate, the peelable protective layer, the hologram layer, the light reflection layer, and the peelable protective layer. It is made by stacking release paper in sequence.

According to the third aspect of the invention, in the openable container, an opening prevention seal formed by coloring the main base material of the seal body is firmly attached to the open / close portion of the container body.

[0012] Here, in particular, the above-mentioned opening preventive seal is an adhesive layer having an adhesive force stronger than the adhesive force of the colored main substrate, the peelable protective layer, the hologram layer, the light reflecting layer, and the peelable protective layer. , Release papers are sequentially laminated.

[0013]

[Action]

 Therefore, in the opening prevention seal of the present invention and the container using the opening prevention seal, the opening prevention seal attached to the opening / closing part of the container is not peeled off by the strong adhesive when the container is opened. The protective seal must be cut. In this case, since the main material of the tamperproof seal is colored, the cut surface of the tamperproof seal becomes easily visible when cut.

With this, it is possible to easily know the open / closed state of the openable container, prevent the container from being opened, and significantly improve the security.

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an external perspective view showing a structural example of a container with an opening prevention seal according to the present invention. That is, as shown in FIG. 1, the container 1 with an opening prevention seal of the present embodiment is opened at an opening / closing portion of an opening / closing container 2 made of, for example, plastic or paper, that is, a position where the opening / closing of the opening / closing container 2 is prevented. The preventive seal 3 is attached so as to be difficult to peel off.

FIG. 2 is a cross-sectional view showing a configuration example of the unsealing 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 protective layer 5, a hologram layer 6, a light reflection layer 7, an adhesive layer 8, and a release paper 9. It is constructed by sequentially stacking. However, when the opening prevention seal 3 is attached to the openable container 2, the release paper 9 is, of course, peeled off.

Here, as the main base material 4, a thickness of about 50 to 100 μm is suitable, and for example, a resin film of polyester, polycarbonate or the like can be used. This main substrate 4 has a role of protecting the hologram layer 6 and, for example, by coloring with a dye, the cross section has a darker color than that seen from the seal surface and is easily visible. ing. Further, the dye is transferred from a transfer paper to a transparent film by a well-known technique such as thermal transfer (sublimation transfer). In this case, in the case of sublimation transfer, the dye penetrates inside the film. Furthermore, as the transfer paper, it is desirable that the transfer paper has the same color on the entire surface and a relatively light color.

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

On the other hand, the embossed relief type hologram layer 6 is formed by coating the acrylic resin, urethane resin, cellulose acetate resin, nitrocellulose resin or the like into a coating material by the same coating method as described above. The thickness thereof is preferably about 0.5 to 2 μm, and a nickel press plate on which a hologram image is formed is heated and pressed against this resin layer to form the hologram layer 6.

The light reflection layer 7 is preferably a metal having a high surface reflectance, and 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. However, the thickness is preferably about 300 to 1000 angstrom.

Further, as the adhesive layer 8, for example, an acrylic resin, a vinyl resin, or the like is used as a main component, and the thickness thereof is set to about 0.5 to 2 μm by the above-mentioned coating method. The adhesive layer 8 has a stronger adhesive force than that of the peelable protective layer 5.

Next, a method of using the container 1 with the unsealing prevention seal of the present embodiment configured as described above will be described with reference to FIGS. 3 and 4.

First, the unsealing prevention seal 3 is bent and attached to a corner (edge portion) so as to close the opening / closing portion of the opening / closing container 2.

On the other hand, in order to open the opening / closing container 2 in which the opening prevention seal 3 is attached to the opening / closing portion in this way, the opening prevention seal 3 has to be peeled off or cut.

However, in this case, since the adhesive layer 8 of the unsealing prevention seal 3 uses a strong adhesive material, it is difficult to peel off the unsealing prevention seal 3. That is, if the opening prevention seal 3 is forcibly peeled off, the adhesive material of the adhesive layer 8 has a stronger adhesive strength than the adhesive strength of the peelable protective layer 5, and therefore the peelable protective layer 5 and the hologram layer 6 Peeling occurs between the hologram layers 6 and the light reflection layer 7. At this time, the hologram layer 6 and the light reflection layer 7 are destroyed because a part of the hologram layer 6 is adhered to the peelable protective layer 5 and a part of the light reflection layer 7 is adhered. It

Therefore, the opening / closing part must be opened by cutting the opening prevention seal 3. 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 base material 4 becomes darker than when viewed from the surface due to the dye contained therein, and the cut surface is easily visible. In this case, even if the unsealing prevention seal 3 is carefully cut, the hologram layer 6 and the light reflection layer 7 are very thin and are easily broken.

On the other hand, even after opening the open / close portion of the open / close container 2 and attaching a cut surface to close the open / close container again, as can be seen from the above, the hologram layer 6 and the light reflection layer 7 are destroyed. Therefore, the cut surface can be easily found.

Further, as shown in the enlarged perspective view of FIG. 4, by using a film having a thickness of about 50 to 100 μm for the main base material 4 (there is a certain elasticity, the two cross sections of the cut end are 90 degrees). It will be in a rotated state), and it is very difficult to bond the cut surface to the original state. That is, since the unsealing prevention seal 3 is once cut, the cross section of the cut surface is visible.

That is, the container has an extremely high security.

As described above, the container 1 with the unsealing prevention seal of this embodiment has a colored main substrate 4, a peelable protective layer 5, a hologram layer 6, and a light reflection layer at the open / closed portion of the openable container 2. The layer 7, the adhesive layer 8 having an adhesive force stronger than the adhesive force of the peelable protective layer 5, and a release paper 9 are laminated in order, and an unsealing prevention seal 3 is firmly attached.

Therefore, when the opening / closing container 2 is opened, the opening prevention seal 3 attached to the opening / closing portion of the opening / closing container 2 has the main base material 4 colored, so that the opening prevention seal 3 When cut, the cut surface becomes easily visible.

With this, the opened / closed state of the openable / closable container 2 can be easily known, and even if the openable / closable container 2 is opened, it can be found immediately, and the opening / closing of the openable / closable container 2 is prevented. It is possible to remarkably improve the security.

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

In the above embodiment, the opening prevention seal 3 is stronger than the adhesive strength of the colored main substrate 4, the peelable protective layer 5, the hologram layer 6, the light reflection layer 7, and the peelable protective layer 5. The case where the adhesive layer 8 having an adhesive force and the release paper 9 are sequentially laminated has been described, but it goes without saying that the present invention is not limited to this.
