Fluid product dispensing device
First Claim
1. A fluid dispenser device including a fluid dispenser member (10) and a dispenser head (20) provided with a dispensing orifice, said fluid dispenser device being provided with dispensing detector means (30, 31) for detecting dispensing of a dose of fluid, said detector means (30, 31) being adapted to deliver a signal for informing the user that a dose of fluid has indeed been dispensed, said detector means comprising a detector (30) for detecting the fluid going from said dispenser member to said dispenser orifice, wherein said detector (30) comprises a piezoelectric material;
- andwherein said detector means are disposed in a sleeve co-operating at one end with said dispenser member and at the other end with said dispenser head; and
said sleeve is made up of two portions engaged one on and surrounding at least in part the other, said detector means being disposed between said two sleeve portions, such that one sleeve portion contacts the dispenser member and not the dispenser head and the other sleeve portion contacts the dispenser head and not the dispenser member;
wherein the detector is tubular and surrounds an inner surface of the sleeve;
wherein one of the two sleeve portions is radially outside the detector and the other of the two sleeve portions is radially inside the detector; and
wherein the fluid dispenser member is a pump or a valve.

12. A fluid dispenser device, comprising:
-
a fluid dispenser member; and a dispenser head provided with a dispensing orifice; the fluid dispenser device comprises a detector that detects a dose of fluid going from the dispenser member to the dispenser orifice, the detector delivers a signal that informs the user that a dose of fluid has been dispensed by the dispenser member, the detector comprising a piezoelectric material; and wherein the detector is disposed in a sleeve comprised of two sleeve portions coupled together, one sleeve portion surrounding at least in part the other;
wherein one sleeve portion forms a fluid coupling with the dispenser member and the other sleeve portion forming a fluid coupling with the dispenser head, the detector located between the two sleeve portions;
wherein one of the two sleeve portions contacts the dispenser member and not the dispenser head and the other of the two sleeve portions contacts the dispenser head not the dispenser member;
wherein the detector is tubular and surrounds an inner surface of the sleeve;
wherein one of the two sleeve portions is radially outside the detector and the other of the two sleeve portions is radially inside the detector; and
wherein the fluid dispenser member is a pump or a valve. - View Dependent Claims (13, 14)
