摘要

The protective closure, made from a moulded plastic material, comprises a closing part 1, which is screwed onto the neck 3 of the container, and an actuating part 12. The latter is connected to the closing part 1 by the engagement, with the possibility of limited vertical displacement, of a collar 10 of the latter in a circular groove 15 of the actuating part 12. On its inner face, the actuating part 12 comprises notches 17 which, when the said actuating part is pushed in, engage with oblique ramps 18 carried by the opposite face of the closing part 1. The invention applies to closures requiring a particular manipulation in order to be opened, as a protective measure.
