Abstract
A tamperproof closure, effective to make any opening attempt irreversibly evident, comprises a cylindrical body adapted for association with a bottle, a cap, a thread connection between the cap and the cylindrical body, a tamperproofing band made unitary with the cap through a weakening line, a plurality of teeth distributed around the cylindrical body and a corresponding plurality of cams distributed around the band, each cam being located before a respective tooth in the unscrewing direction of the cap and interfering with the tooth during the unscrewina operation so as to be displaced outwardly and distort the band locally into a projection.
