Abstract
The present invention is directed to a tampering/opening evidence mechanism to avoid the adulteration and reuse of packages, which corresponds to a device having a dual lid with a series of mechanisms that, when the user turns the lid to open the product, make the side surface thereof to be stained by an ink located therein. Thus, the mechanism of the invention stains with a permanent/indelible ink the inside of the dual lid, when it is rotated by the user for the first opening of the container, and wherein said movement allows both surface to be stained due to an element, such as a foam, being charged with ink which stains both surfaces with the rotation of the lid.
