1.tapºn-precinto for bottles and containers of threaded neck, preferably of plastic material, characterized in that, being molded in one piece, comprises a cylindrical inner annular skirt, which constitutes the seal and is attached to the bottom edge of the cap itself by several thin arcuate joining strips, arranged in respective notches made in the upper edge of the skirt-seal, the latter being provided on its internal face with multiple projecting protrusions of the same, with a right triangle plan, which determine a toothing in sawtooth, adapted to cooperate with corresponding projecting protuberances, arranged annularly around the neck of the bottle or container, also in right-angled plan, but determining saw teeth of inclined planes directed in a rotary direction opposite to that of the inclined planes of the serrated inside the skirt-seal, all this so that the stopper, together with the skirt-seal attached to it, can be screwed into the neck of the bottle or container to its closed position, thanks to the successive facing of the inclined planes of the internal toothing of the skirt in the direction of screwing- seal and the projections protruding from the neck of the bottle or container, while unscrewing the cap to open the bottle or container, collide with each other the vertical planes of the toothing of the skirt-seal and the neck of the bottle or container, preventing the rotation of the skirt and therefore of the stopper, until the thin strips of unión between the skirt-seal and the stopper break, which determines the unsealing of the stopper, the skirt-seal being then retained below a stopper. Annular rib disposed just above the projecting protuberances. 2.tapºn-precinto for bottles and containers of threaded neck. (Machine-translation by Google Translate, not legally binding)
