ABSTRACT:
The invention provides a security closure, particularly for single-measure bottles, of the type in which a screw cap is connected by breakable links to a ring engaged with a flange on the bottle neck. The lateral wall of the cap has at least one portion which is cut along its edges facing the rest of the wall and is connected to the ring by one or more breakable links only. When the cap is unscrewed and the links are broken the wall portions are completely detached and fall away from the cap so that, if the cap is subsequently screwed back into contact with the ring, the fact that the wall portions are missing will warn the consumer that the closure is broken.
