Abstract
A device for closing a container having a neck, in particular a bottle or pot for a cosmetic product, of the type having structure for axial tightening by screwing of a cap onto the neck of the container and for the angular positioning of the cap with respect to the container. The angular positioning structure comprises at least one lug of the container extending substantially axially upwards from a shoulder surface of the container substantially perpendicular to the tightening axis and at least one tongue member of the cap which is elastically deformable in the axial direction co-operating with such lug in order to vary the axial tightening force at the time of the opening and closing operations.
