A cap for a container comprising a ferrule to be fixedly attached to the neck of the container, the ferrule comprising an upper wall and a tubular skirt extending downwardly from the upper wall; a tamper evidence mechanism connected with the ferrule; an overseal button removably arranged on top of the upper wall of the ferrule so as to at least fully cover the tamper evidence mechanism, the overseal button being connected to the tamper evidence mechanism such that upon first removal of the overseal button the tamper evidence mechanism is irreversibly damaged. The overseal button comprises at least one translucent portion arranged to extend over the at least one portion of the tamper evidence mechanism which is irreversibly damaged upon first removal of the overseal button.

A crown cap, configured based on a sheet with a circular body perimetrally presenting, after being adjusted to the rim of the mouth of a bottle, a plurality of folds. The sheet has an extension that extends from the circular body and a first transverse folding line to determine a folded arm with two sections, an upper, external section that extends from the circular body followed by a lower, internal section, located between the external or front section and the bottle. The extension also has a continuous cut on the external section that determines a flap with an inverted U-shaped surface, the continuous cut allowing the flap to bend out of a plane of the external section so that during removal of the cap from the bottle, a distal end of the flap engages an area where the extension extends from the circular body.

A closure cap having a hollow cylindrical body. The body includes a capsule-shaped cap portion and an open annular band, which is made integral in a breakable way with the cap portion by a breakable circumferential edge having a narrow thickness. At least one flexible tab is attached to the annular band such that the annular band can be removed by pulling the tab to break the breakable circumferential edge. At least one deformable annular protrusion having an external diameter which is greater than the external average diameter of the cylindrical body is on the side surface of the cap portion. The annular protrusion is configured to deform when a pressure higher than a predefined pressure threshold value is reached inside the cylindrical body. The closing wall is configured to rise following the deformation of the annular protrusion.
