1. A capping device intended to be attached to a neck of a container that includes an orifice, a support collar and a coupling flange, including the capping device:
a lower ring fixed axially to the neck and movable in rotation on the neck around that X-axis, including this lower ring a first section that includes two engagement areas in which engaging elements protrude radially toward the inside of the lower ring and are intended to be placed under the coupling flange to retain axially the bottom ring on the neck of the container and a second section, with the first section and the second section of the lower ring articulated to each other so that the second section pivots with respect to the first section between a lowered position in which the second section is arranged below the coupling flange and a raised position in which the second section is arranged at least partially above the coupling flange,
a cap including an upper wall and an external peripheral skirt, presenting the external peripheral skirt a helical thread intended to cooperate with a helical thread of the neck to allow the movement of the cap between a closed position and a released position in which the helical thread of the cap is no longer present coupled with the helical thread of the neck ring;
an articulation device that joins the cap to the second section of the lower ring and is configured to allow the cap to pivot between the released position and an open tilted position in which the cap is removed from the orifice of the neck;
including the first section a front area which is diametrically opposed to the second section, with the two engagement areas located respectively on one side and the other side of the front area, between that front area and the second section, presenting the front area of the first section a height lower than the two engagement areas of the first section and the second section and being configured to fit between the support collar and the coupling flange during the movement of the second section between the lowered position and the released position to allow radial movement of the lower ring,
wherein the second section of the lower ring includes an internal face having at least one hole.
