Closing cap for a container

A closing cap (1) for a container (2), comprising a lateral wall (3) extending around an axis (Z) and a transversal wall (4) positioned at one end of the lateral wall (3), a separating line (5) being provided on the lateral wall (3) to define a retaining ring (301), which is configured to remain anchored to the neck (201) of the container (2), and a closing element (302) removably engageable with the neck (201), so as to open or close the container (2);

• wherein the separating line (5) extends around the axis (Z) and is circumferentially interrupted to define in the lateral wall (3) a joining zone (305), which extends circumferentially for a first angular portion (α), in which the retaining ring (301) and the closing element (302) are joined;
• wherein the lateral wall (3) comprises a first cut (601), a second cut (602) and a projection (8), which projects from the lateral wall (3) and is configured to rest on the neck (201) in an open condition, wherein the first cut (601) and the second cut (602) extend circumferentially within a second angular portion (β) which is contained in the first angular portion (α) and the projection (8) is circumferentially positioned between the first cut (601) and the second cut (602);
• wherein the retaining ring (301) comprises a retaining portion (303) and a free portion (306) which extend as far as a free edge (304), the retaining portion (303) being configured to internally engage with a stop ring (206) of the neck (201), during a passage from a closed condition to an open condition of the closing element (302);
• the free portion (306) being configured to allow an axial movement at least of the second angular portion (β) of the retaining ring (301) during said passage, wherein each cut (601;
• 602) is formed by a cutting line passing through the lateral wall (3), wherein each cut (601;
• 602) comprises a respective breakable element (603;
• 604), suitable for breaking when the cap (1) is opened for the first time to define a tab (308) within which the projection (8) is positioned.
