A pilfer-proof closure has an inwardly threaded side wall (7) terminating (at 10) at or just below an annular flange means (17) on the neck of the container (14). Shrunk-in below the flange means (17) is a tamper-evident band (9) joined by a small number (usually 3) of bridges (11, 12, 13). One of the bridges (13) is preferably made weaker than the others.
