The invention concerns a plastics screw-type cap for bottles, said cap having a body with an internal thread and a tamperproof strip which has at least one expansion device. The expansion device comprises at least one point at which it is fixed to the cap body. In this way, a screw-type cap is produced which has a reliable tamperproof function and whose tamperproof strip, when the cap is unscrewed, remains on the cap body without free ends of the strip protruding from the cap body. |
