Adhesive material for preventing reuse

DETAILED DESCRIPTION However, such labels have the disadvantage of being high in cost, because the film, as the material on to which the metal is being vaporized, is limited to polyester or the like and other various conditions must be satisfied, as the metal is vaporized on to the film and the silicon layer.
Moreover, there were further disadvantages such as sanitary problems caused by the attachment of dust on the tacky surface of the exposed adhesive layer, due to a part of the adhesive layer remaining on the adhering portion of the material being adhered on, when the film was torn off.
Therefore, a principal object of the present invention is to provide an adhering material for preventing reuse, which is sensitive to the separation after the adhesion and does not require any vaporizing process.
The present invention is, to be brief, an adhering material for preventing reuse comprising an adhesive layer, a second layer, which can be cut or torn by fingers and laminated on the adhesive layer, an adhesion layer laminated on the second layer and a first layer laminated and adhered temporarily to the adhesion layer.
According to the present invention, the second layer is adhered temporarily to the first layer by the adhesion layer, thus it can be formed without vaporization as in the past.
In addition, since the first and second layers are adhered temporarily, whereby re-adhering is impossible by the adhesive layer, when any attempt is made to tear the adhering material off from the opening of the package and so on, the first layer will come off from the second layer and the re-adhering thereof is no longer possible, thus it is clear that the adhering material that had been adhered on is torn off.
Furthermore, when the second layer has been cut or torn, it will not return to its original state, so that the separation of the first layer can be distinguished.
Thus, separation of the adhering material that had been adhered on can be seen at a glance, and the adhering material without the vaporization process used hitherto, may be obtained
