Closure with evidence of first opening

Abstract

The present invention is a tamper-evident closure intended for installation on the mouth of a container, preferably a bottle, such that it not only prevents fraudulent refilling but also makes its appearance and external configuration evident when it has been opened at least once. The tamper-evident mechanisms are not only more secure than those known in the prior art but are achieved with fewer parts and simultaneously accommodate several security mechanisms to prevent both fraudulent opening attempts and copying.
