Реферат: This tamper-evident closure (1) comprises: an outer cap (2) with a sidewall (21) and a top wall (23) having a tamper-evident member (24) connected to a surrounding region (25) by a frangible structure (26); an inner cap (4) with a sidewall (41) and a top wall (43), coaxially nested in the outer cap with possibility of relative axial movement of the top walls (23, 43) toward each other; a protruding element (46) arranged between the top walls (23, 43) facing the tamper-evident member (24); a first engagement mechanism (52, 54) for driving the outer cap and the inner cap in unison upon application on the outer cap (2) of a rotational torque in the direction of screwing (R 1 ); a second engagement mechanism (72, 74) for driving the outer cap and the inner cap in unison upon application on the outer cap (2) of a rotational torque in the direction of unscrewing (R 2 ) at the same time as an axial force (F); a third engagement mechanism (82, 84) for breaking the frangible structure (26) upon relative rotational movement of the outer and inner caps when the outer cap is rotated in the direction of unscrewing (R 2 ), regardless of an axial force applied on the outer cap.
