Abstract:
Capping device comprisinga cap, a lateral skirt of which is equipped with a means for engagement with a container, it being possible for the cap, in one position, to be placed over an opening of the container so as to close the container and, in another position, to be released from the opening so as to allow access to the inside of the container; a ring engaged on the container to delimit said opening and held axially thereon; and two arms in the form of an arc of a circle, each one of which is connected to the cap by a film hinge and a foldable means, and to the ring, the arms being connected to the ring at locations which are angularly distant with respect to the film hinge; said foldable means allows pivoting of the arms between a folded position, in which the arms are placed close to the ring and in which the cap is axially close to the ring, and an unfolded position, in which the arms are pivoted with respect to the film hinge and to the ring and allow the cap to be brought into a position which is axially remote from the ring, this position being sufficient to make it possible to release said means for engaging the cap with the container and to tilt said cap outwards with respect to the container so as to bring the cap into the position in which it is released from the opening of the container; wherein the cap comprises a bearing means which, during said tilting, bears against the container and exerts, a pulling on the arms, the pulling being minimal in the positions of engagement of the cap over the opening of the container and of total release of the cap from the opening, but being maximal in the intermediate position of the cap between these two positions.
