Abstract
The present invention relates to a tamper evident closure in which the outer portion (10) rises upon first opening, and having means that prevent such outer portion from falling back to the original position once it has risen. Therefore, the tamper evident effect is given by the misalignment of the outer portion and the central portion (8). The closure may be made of cork, possibly of synthetic nature, or of screw type, adapted to be tightened to a threaded pouring device applied to the neck of the bottle.
