Abstract A circular tamper-proof closure device and process for sealing threaded bottles, jars, and similar containers are disclosed. The closure comprises a sealing ring containing a peripheral lip, a wedge-shaped security ring, retaining bridges to join the sealing ring to the security ring, an annular stop to limit the movement of the security ring, and a metallic cap with a rim that is wedged into the sealing ring between the lip and the security ring. The closure is fastened to the threaded bottle by securing the sealing ring to the bottle and forming threads on the metallic cap.
