Abstract
A fluid dispenser including, a fluid reservoir with a neck 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 that is mounted on the neck by a fastener member in engagement both with the threaded neck and with the dispenser member. The fastener member includes a ring, the ring forming: a reception mechanism for receiving the dispenser member; an annular ledge; and a skirt that is in engagement with the threaded neck. The ring includes a rupture mechanism 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 remove the dispenser member from the reservoir.
Claims15
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.

A fluid dispenser comprising:
- a fluid reservoir provided with a neck that is externally threaded and that internally defines an opening that communicates with an inside of the reservoir, the neck forming at least one helical thread defined by a projecting helical rib having a helical top surface portion and a parallel helical bottom surface portion;
- and
- a dispenser head that is mounted on the neck of the reservoir, the head 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 comprising a ring, the ring forming an opening having a support for the dispenser member, the support extending radially inward;
- and a skirt configured to be in threaded engagement with the at least one helical thread;
- wherein the ring includes a weakened portion configured to rupture and separate a lower portion of the ring from an upper portion of the ring so as to separate the support from the skirt by turning the ring on the threaded neck and so as to allow removal of the dispenser member from the reservoir
- the neck comprises an annular peripheral lip disposed above the thread, the lip defining an annular shoulder below which the skirt comes into abutment preventing the skirt from being unscrewed from the threaded neck;
- the skirt is malleable in such a manner as to deform on the threaded neck;
- the fastener member further comprises a rigid hoop 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 weakened portion is ruptured and the ring with the skirt is removed, the ring with the skirt is no longer configured to be screwed on the threaded neck.
