A re-closable tamper-proof closure assembly for containers comprises a cap with a tamper-proof strip attached to the skirt of the cap by a breakable web but the strip is free of any tabs graspable by the user\s hand, and is broken away from the cap simply by the act of removing the cap by pushing upwards on a stout lug. There may be a gap in the web already in the region of the lug, and at the opposite side of the cap the skirt is extended downwards to form a tongue between the ends of the strip. There can be a bead on the container neck for snap engagement of the cap on re-use, in addition to the bead engaged by the tamper-proof strip.

A re-closable tamper-proof snap-on closure assembly comprising a closure cap, said cap having a peripheral skirt, a tamper-proof strip below said skirt and joined to said skirt by a circumferentially extending weakened breakable web, said strip being free of any graspable finger tab, and a co-operating container neck onto which said cap fits, said neck being provided with an external circumferentially extending bead formation under which said strip engages when said cap is in place, said cap being provided with an outwardly extending finger-engageable lug, a gap formed in said breakable web in the region of said lug allowing a user to push upwards on the region of the cap that carries said lug thereby separating said cap from said strip initially in said region at opposite sides of said gap, and the arrangement being such that continued upward pressure on said lug flexes said cap and progressively tears said web until said cap and tamper-proof strip are both free of said container neck.
