ABSTRACT:
Cap of a type suitable to be used for the momentary closure of bottles containing gaseous or aerated liquids, the cap comprising an outer sheath (13, 113) open at its lower end, within which is installed a longitudinally slidable supporting and closure element (14) including at its lower end a seal (15) which is rested on the mouth (12) of the bottle. The supporting and closure element (14) cooperates at its upper end with resilient thrust elements (16) firmly secured to the outer sheath (13, 113) and also comprising anchorage legs (18, 118) which can be deformed resiliently in a radial direction and which bear terminal claw elements (19, 119), the anchorage legs (18, 118) cooperating with a clamp having at least one first working position, in which the cap (10) is anchored to the bottle, and a second inactive position, in which the cap is free to be withdrawn from the bottle. The clamp has coordinated projections (22, 122) which can be arranged circumferentially against the anchorage legs (18, 118), the projections (22, 122) cooperating momentarily with the anchorage legs (18, 118) so as to clamp the same against the neck (11) of the bottle.
