1. A capping device intended to be attached to a neck of a container which includes a hole and an engaging collar, the capping device comprising:
a cap which includes an upper wall and an outer peripheral skirt, with the outer peripheral skirt having a thread formed by a series of ribs and intended to cooperate with a thread formed in the neck to allow:
unscrewing of the cap from the neck around an X-axis to move the cap from a closing position where the upper wall closes the hole of the neck and the outer peripheral skirt surrounds the neck to a released position where the cap is no longer attached to the neck, wherein the X-axis defines an axis of rotation of the cap; and
screwing of the cap to the neck to move the cap from the released position to the closing position;
a lower ring engageable to the neck and movable in rotation about the neck about the X-axis, wherein the lower ring includes a first sector comprising engaging elements, which project radially into the lower ring and are intended to be arranged under the engaging collar to retain the lower ring axially relative to the neck of the container, and a second sector, the first sector and the second sector of the lower ring are pivotally connected together so that the second sector pivots with respect to the first sector between a lowered position where the second sector is intended to be positioned under the engaging collar and a raised position where the second sector is intended to be at least partially positioned above the engaging collar, such that a bottom surface of the second sector is not in the same plane as a bottom surface of the first sector when the second sector is in the raised position; and
a hinge device that connects the cap to the lower ring, the hinge device including two plates that connect the outer peripheral skirt and the lower ring and are arranged to allow the cap to rotate between the released position and an open tilted position in which the cap disengages from the hole of the neck, the capping device in addition including a locking device configured to lock the cap in the open tilted position, such locking device including a bead which is formed on the outer peripheral skirt, between the two plates, and which is configured to rest against the neck of the container when the cap is in the open tilted position, the bead has an internal face where at least one of the ribs of the thread series is formed.
