CLOSING CAP FOR A CONTAINER

What is proposed is a closing cap (1) for a container, comprising a lateral wall (3) extending around an axis and a transversal wall (4) positioned at one end of the lateral wall, a separating line being provided on the lateral wall to define a retaining ring (301), which is configured to remain anchored to the neck (201) of the container, and a closing element (302) removably engageable with the neck, so as to open or close the container. The separating line extends around the axis and is circumferentially interrupted to define in the lateral wall a joining zone (305), which extends circumferentially for a first angular portion, in which the retaining ring and the closing element are joined. The lateral wall comprises a first cut (601), a second cut (602) and a projection which projects from the lateral wall, wherein the first cut and the second cut extend circumferentially within a second angular portion which is contained in the first angular portion, the projection (8) being circumferentially positioned between the first cut and the second cut. The retaining ring comprises a retaining portion (303) and a free portion which extend as far as a free edge, the retaining portion being configured to internally engage with a stop ring (206) of the neck, during a passage from a closed condition to an open condition of the closing element; the free portion (306) being configured to allow an axial movement at least of the second angular portion of the retaining ring during said passage.
