Abstract:
A fluid dispenser device compromising a reservoir (10) containing one or more doses of fluid, a dispensing orifice (20), and a dispensing member (30), said reservoir being of the syringe type (10) having a hollow tube (11) provided with an upstream opening (12) and with a downstream opening (13), said upstream opening (12) being prided with a piston (40) which, at rest, forms a leaktight stopper, and which co-operates with an actuating rod (30) forming the dispensing member, and said downstream opening (13) being provided with an end-piece (50) firstly incorporating closure means (51) for forming a leaktight stopper at rest, and secondly adapted to define a spray profile (55) when the deice is actuated, the device being characterized in that said end-piece (50) has a fixing portion (54) fixed in leaktight manner to said downstream opening (13)of the syringe (10) so that the unit formed by the reservoir (10), the piston (40), and the end-piece (50) can be prefilled and closed off in leaktight manner before the device is assembled, said syringe (10) and said end-piece (50) being inserted, during assembly, into an outer body (80) incorporating the dispensing orifice (20) of the device.
