Abstract

Twist-off cover for container, comprising a screw cap (1) and a sealing device which fixes the screwed-down cover by means of a plastics ratchet ring (9) on the flange against being twisted off and which releases the cover only on account of a recognizable change thereat, wherein the cover (1) seated on the flange is wedged between the cover and the foot of the flange, characterised in that the ratchet ring (9) is joined by means of plastics film joints (17) to concentric retaining ring portions (15) which surround the cover (1) concentrically, wherein the cover (1) is provided with locking elements (7) that project outwardly and have cutting edges (31) which between the ratchet ring (9) and the retaining ring portions (15) are directed circumferentially towards the plastics film joint (17).
