1. A closing cap for a container, the container having an opening in a neck provided with an outer threaded portion, the closing cap comprising:
a lower ring coupled to the neck of the container and an upper cap that has on the inner face thereof a thread coupled to the outer threaded portion of a container neck,
the upper cap and the lower ring being joined to each other in such a way that they are able to rotate together,
wherein the connection between the upper cap and the lower ring is carried out by two flexible extensions that are diametrically opposed to each other, each flexible extension of the two flexible extensions formed from a thickening present in the lower ring that includes a grooved portion such that the two flexible extensions are formed above the grooved portion in such a way that the two flexible extensions have the same outer diameter as the outer diameter of the thickening, the lower edge of the body of the upper cap having a step that defines a recessed portion in which the two flexible extensions are located, and such that in a closed condition the two flexible extensions are arranged above and parallel to the body of the lower ring;
while in an open position of the closing cap, respective upper ends of each flexible extension of the two flexible extensions act as a hinge region in such a way that the upper cap is able to rotate, and in which the interior of the lower ring includes retaining means intended to act on a perimeter projection present on a container neck, such retaining means being disposed on the inner diameter of the body of the lower ring, in such a way that the regions are aligned in height with the position where each flexible extension of the two flexible extensions is generated from the lower ring are devoid of such retaining means such that the two flexible extensions flex responsive to a vertical movement of the lower ring.
