1. A cap to be applied on a neck of a container comprising:
a retaining ring suitable for being associated with the neck of the container;
a closing element comprising a lateral wall which extends around an axis and a transversal wall which extends transversally to the axis for defining a closed end of the closing element;
a hinge band structure;
wherein the closing element comprises a projection which projects from an outer surface of the lateral wall transversally to said axis, the projection extending around said axis by an angle of at least 180°, wherein the projection projects from the lateral wall by a radial dimension, the radial dimension being variable around the axis, the radial dimension gradually increasing from the hinge band structure to a region diametrically opposite the hinge structure;
wherein the projection has, in a plane perpendicular to said axis, a circular perimeter defined by a circle having a centre which lies outside of said axis; and
the projection is provided with a provided with a plurality of stiffening ribs extending on a surface of the projection facing towards the transversal wall, the plurality of stiffening ribs comprises two end stiffening ribs which delimit the front part on opposite sides and extend in respective planes parallel to the axis,
the plurality of stiffening ribs comprising further ribs lying in respective further planes parallel to the axis which do not contain the axis, the further planes forming, with a plane defined by the nearest end stiffening rib, respective angles which increase from the front part to the hinge band structure; and
the stiffening ribs being absent in a front part arranged in a position diametrically opposite the hinge band structure.
