Abstract
A fluid dispenser device comprising a reservoir (10) containing one or more doses of fluid, a dispensing orifice (20), and a dispensing member (30), said device being characterized in that said reservoir is 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 provided 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 device is actuated.

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.
A fluid dispenser device, compromising:
- an outer body (80) comprising a dispensing orifice (20);
- a reservoir (10) containing one or more doses of fluid;
- and
- a dispensing member (30);
- and wherein
- the reservoir has a hollow tube (11), comprising:
- an upstream opening (12);
- a downstream opening (13);
- a piston (40) disposed at or near (he upstream opening (12) and which, at rest, forms a leaktight stopper;
- an actuating rod (30) that, when actuated, moves the piston within the reservoir;
- and
- and end-piece (50) disposed at or near the downstream opening (13), the end-piece comprising a closure member that closes off in a leaktight manner the downstream opening (13) when the actuating rod is at rest, the end-piece cooperating with the outer body to define a spray profile when the actuating rod is actuated;
- and wherein the end-piece further comprises a fixing portion (54) fixed in leaktight manner to the downstream opening (13) of the reservoir so that the assembly formed by the reservoir (10), the piston (40), and the end-piece (50) are configured to be prefilled and closed off in a leaktight manner before assembling of additional pieces.
