Abstract
A stopper for a container providing evidence of first opening includes an upper part with a protection cap closable on a pouring element and a ridged lower part with an upper hollow cylindrical portion disposed inside the pouring element and a lower cylindrical portion of larger diameter that is internally threaded. A frangible label is positioned between the protection cap, and a security ring is connected with the upper and lower parts with frangible bridges. An annular security crown is connected to the lower part of the stopper by frangible bridges and a cam arrangement, coaxially coupled between an outer surface of the upper hollow cylindrical portion and an inner surface of the pouring element, causes their translation and rotation. The pouring element has a duct passage and a coaxial island shutter which cooperates with a central hole in the upper hollow cylindrical portion of the lower part.
