Abstract
A cap for closing a neck of a bottle is disclosed. The cap includes a lid for closing off the neck and a skirt for fixing to the neck. The skirt is provided with a bulge line for interfering by wedging with the neck, a weakened line to be ruptured by propagation of a tear, and a stop means for preventing the tearing propagating in the rectilinear extension of a first part of the weakened line that runs along the bulge line while being situated on the side of the latter opposite to the lid. The weakened line also includes second and third substantially rectilinear parts which, on the periphery of a skirt, follow on respectively from the first part to the second part of the weakened line. The second part of the weakened line avoids the stop means and extends on either side of the bulge line, while being inclined both with respect to the bulge line and with respect to the direction of the axis of the skirt. The third part of the weakened line extends along the bulge line while being situated on the side of the bulge line turned towards the lid.
