The invention concerns a safety screw cap for sealing a bottle, comprising a tamperproof system, characterised in that it mainly consists of two concentric parts, an inner part in the form of a top (1) whereof the skirt (2) comprises an internal threading designed to be engaged on a bottle (12) neck threading, and an outer protective part in the form of a shell (4), the latter being a roofless shell opening upwards and downwards, and the shell (4) and the top (1) are provided with vertically shaped grooves such that if there is an attempt to unscrew the top without removing the shell, the latter rotates without transmitting the torque. |
