Device For Dispensing Liquid Product Provided With A Flow Reduction Member

1 . A liquid dispenser device comprising:

a dispenser endpiece including a cavity having an end wall from which there extends a longitudinal liquid outlet channel; and

a flow reducer member that is fitted in the cavity of the endpiece, said flow reducer member including a transverse surface that co-operates with the end wall of the endpiece to define a liquid deflector channel that extends in a transverse plane, the deflector channel being non-rectilinear, and an essentially longitudinal feed channel through which liquid flows, and in which the liquid deflector channel forms a junction between the outlet channel and the feed channel.

2 . A device according to claim 1 , wherein the end wall of the endpiece includes a transverse surface that is substantially plane, and the transverse surface of the flow reducer member includes portions in relief that co-operate with the end wall of the endpiece to define the liquid deflector channel.

3 . A device according to claim 2 , wherein the flow reducer member includes a base having a support function, carrying the portions in relief, and having a height in the longitudinal direction that is greater than the height of the portions in relief.

4 . A device according to claim 1 , wherein the transverse surface of the flow reducer member is substantially plane, and the end wall of the endpiece includes portions in relief that co-operate with the transverse surface of the flow reducer member to define the liquid deflector channel.

5 . A device according to claim 4 , wherein the feed channel is defined entirely by the flow reducer member.

6 . A device according to claim 1 , wherein the flow reducer member is pressed against the end wall of the endpiece in the longitudinal direction.

7 . A device according to claim 1 , comprising only two parts: the dispenser endpiece and the flow reducer member.

8 . A device according to claim 1 , wherein the flow reducer member includes a closure wall for closing the outlet channel, which closure wall is elastically movable between a rest configuration in which liquid can pass, and a deformed configuration in which the wall is pressed against the outlet channel so as to close it, at least in part.

9 . A device according to claim 8 , wherein the closure wall is connected to a base of the flow reducer member via a deformable wall, the deformable wall presenting a thickness that is small relative to the thickness of the base.

10 . A device according to claim 1 , wherein the flow reducer member is made out of a flexible material.

11 . A device according to claim 1 , wherein the flow reducer member is non-porous.

12 . A device according to claim 6 , wherein the flow reducer member fastened against the end wall by one of snap-fastening, clamping, or ultrasonic welding.

13 . A device according to claim 10 , wherein the flexible material is an elastomer material.
