Fluid product dispensing device
Abstract:
A fluid dispenser device comprising a body (1) provided with a dispenser orifice (2), a reservoir (10) containing at least one dose of fluid being disposed statically in said body (1), said reservoir (10) being closed in sealed manner by two stoppers (20, 30), a first stopper (20) and a second stopper (30), the fluid being disposed in a fluid chamber (11) situated between said first and second stoppers (20, 30), said device further comprising opener means (40) for opening said first stopper (20), said opener means (40) being disposed statically in said body (1), actuator means (50) being connected to said second stopper (30) so as to displace it in said reservoir (10), the actuation of said second stopper (30) creating pressure in the fluid chamber (11); said pressure displacing and/or deforming said first stopper (20) towards said opener means (40), in such a manner that firstly said first stopper (20) is opened, and then fluid is expelled through said open first stopper (20) towards said dispenser orifice (2), a spray profile (50) being provided downstream from said dispenser orifice (2), the device further comprising precompression means (70) so as to create precompression in the reservoir (10) before said first stopper (20) is opened by said opener means (40), so as to improve the spraying of the fluid, and so as to ensure that the entire dose of fluid is dispensed.
