Abstract:
1. A fluid dispenser comprising: a fluid reservoir provided with a neck that is externally threaded and that internally defines an opening that communicates with the inside of the reservoir, the neck forming at least one helical thread; and a dispenser head (T) that is mounted on the neck of the reservoir, the head (T) comprising: a dispenser member; a pusher for actuating the dispenser member; and a fastener member that is in engagement both with the threaded neck of the reservoir and with the dispenser member; the fastener member including a ring, the ring forming: reception means for securely receiving the dispenser member; an annular ledge for exerting pressure on the neck; and a skirt that is suitable for coming into engagement with the threaded neck; wherein the ring includes rupture means between the ledge and the skirt so as to separate the ledge from the skirt by turning the ring on the threaded neck, in such a manner as to make possible removal of the dispenser member from the reservoir; the dispenser further comprises abutment means preventing the skirt from being unscrewed from the threaded neck; the neck comprises an annular peripheral lip situated above the thread, the lip defining the abutment means in the form of an annular shoulder below which the skirt comes into abutment when attempting to unscrew the skirt from the neck; the skirt is malleable in such a manner as to deform on the threaded neck; the fastener member further comprises a rigid hoop that is engaged around the skirt so as to push the skirt radially against the threaded neck in such a manner as to deform the skirt against the thread of the neck and create a thread indentation in the skirt and to lock the skirt under the annular shoulder; and wherein once the ring with the skirt is removed, the ring with the skirt is no longer screwable on the threaded neck.
