Abstract incl. reference numbers (as desired by WIPO) In a screw closure for wide-necked containers which is provi- ded with a tamper-evident safeguard and comprises a cover de- signed to be placed on the neck of the container and a secu- rity ring (2), the security ring is provided with lugs (7) which, in the closed position of the cover (1), engage behind a projection of the neck of the container. Corresponding bul- ges (17) for the lugs (7) or for the security ring are provi- ded on the neck of the container at the level of the security ring, being arranged and designed in such a way that, when the lug or the security ring passes over the bulge on opening of the screw closure, the security ring is expanded and breaks under the effect of weakened spots formed in the secu- rity ring.
