Fluid product dispensing device

Abstract

A fluid dispenser device including a fluid dispenser member ( 10 ) such as a pump or a valve, and a dispenser head ( 20 ) provided with a dispensing orifice, said fluid dispenser device being characterized in that said device is 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 by said pump, said detector means comprising a detector ( 30 ) for detecting the fluid going from said dispenser member to said dispenser orifice.

       20 . A fluid dispenser device including a fluid dispenser member ( 10 ) such as a pump or a valve, 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 by said pump, said detector means comprising a detector ( 30 ) for detecting the fluid going from said dispenser member to said dispenser orifice, said fluid dispenser device being characterized in that said detector ( 30 ) comprises an optical fiber ( 30 ). 
   
   
       21 . A device according to  claim 20 , in which the dispenser member ( 10 ) is connected to the dispensing orifice ( 40 ) via an expulsion channel ( 50 ), said detector means ( 30 ,  31 ) being provided in said expulsion channel ( 50 ). 
   
   
       22 . A device according to  claim 20 , in which said optical fiber ( 30 ) is associated with a deformable membrane ( 31 ) which deforms when fluid passes through it, such deformation generating stress in the optical fiber ( 30 ). 
   
   
       23 . A device according to  claim 22 , in which said deformable membrane ( 31 ) is disposed around a portion of said expulsion channel ( 50 ). 
   
   
       24 . A device according to  claim 22 , in which said optical fiber ( 30 ) co-operates with said deformable membrane ( 31 ) in a casing ( 45 ) secured to the dispenser head ( 20 ). 
   
   
       25 . A device according to  claim 20 , in which said optical fiber ( 30 ) is made of plastic or of glass.
