A threaded cap and neck set for evidencing tampering with containers (13), comprising:

• a neck of a container having a cylindrical shape and an aperture, said neck having threads on its outer surface and a sealing collar, wherein said sealing collar comprises a plurality of teeth;
• and
• a cap with a thread portion having a cylindrical shape and having threads on its inner surface, said cap including a tamper-evident ring coupled to a lower rim of said cap, wherein said tamper-evident ring has a diameter greater than a diameter of said cap;
• wherein said tamper-evident ring comprises a plurality of reversible grippers projecting longitudinally from said tamper-evident ring, wherein said reversible grippers are coupled to said lower rim of said tamper-evident ring by means of a hingeable membrane;
• wherein at least one of said reversible grippers comprises a hingeable locking mechanism relative to said gripper, wherein:
• the hingeable locking mechanism consists of a flap attached to said reversible claw of said cap by a flexible membrane;
• and
• wherein said flap has a shape which, by rotational movement in the closing direction of said cap on a bottle, said flap hinges with respect to said flexible membrane to a releasing position allowing the passage thereof on said teeth of said bottle neck;
• and, by rotational movement in the opening direction of said cap on the bottle, said flap hinges with respect to said flexible membrane to a locking position which does not allow the passage thereof on said teeth of said bottle neck.
