ABSTRACT:
A closure device for a recipient with a threaded neck. It includes a tapped closure having a lower part attached to a guarantee strip by a zone of connection of low mechanical resistance, the strip presenting an elastically-deformable, inner, annular bead adapted to clip beneath a holding flange formed on a lower periphery of the neck by forced screwing of the closure; and an outer peripheral boss axially separated from the bead by a zone of controlled elastic deformation, an upper face of the boss and a lower edge of a lateral wall of the closure having formed therein, respectively, at least one tooth and at least one notch, the tooth being intended to be temporarily received in the notch during screwing when the bead is in abutment with the holding flange in order to avoid any relative rotational displacement of the closure with respect to the strip and to ensure clipping without deteriorating the zone of connection.
