A plastic closure element for containers (1) for liquids comprises a liquid outlet mouth (2) formed by the neck (3) of the container (1) having a ring-shaped rib (4) ; the element (100) comprises: a first body (5) , formed by an upper closure surface (6) and a discontinuous ring-shaped cover, sharing an axis (Z) , extending from the surface (6) and formed by at least a first plurality (7) of tabs, each tab having an elastically yielding radial projection (8) ; a second body (9) , encompassing and engaging with the first body (5) and having a ring-shaped surface (10) for contact with the first plurality (7) of tabs in a projections (8) minimum radial dimensions configuration, in which they are in contact with the ring-shaped rib (4) on the neck (3) , forming a closure element (100) tightening configuration on the container (1) ; the second body (9) has a set of seats (11) designed for the radial projections (8) to engage in, when the second body (9) slides axially relative to the first body (5) along the axis (Z) , in such a way as to form a first plurality (7) of tabs maximum radial dimensions configuration corresponding to a container (1) open configuration. |
