A fluid dispenser device comprising a body (10) defining a dispensing orifice (11), and a reservoir (20) containing one or more doses of fluid, said reservoir (20) having a piston (25) which, at rest, forms a leaktight stopper, said device being characterized in that it further comprises a resilient

A fluid dispenser device comprising a body (10) defining a dispensing orifice (11), and a reservoir (20) containing one or more doses of fluid, said reservoir (20) having a piston (25) which, at rest, forms a leaktight stopper, said device being characterized in that it further comprises a resilient element (30), such as a spring, that co-operates firstly with said reservoir (20) or with said piston (25), and secondly with a cocking member (40), said cocking member (40) being mounted to be movable manually relative to said body (10) so as to compress said spring (30), and being mounted to be lockable relative to said body (10) in at least one locked position in which said spring (30) is compressed, said device including at least one triggering member (50, 51) adapted to release said spring (30) so as to move said at least one piston (25) relative to said reservoir (20) so as to expel a dose of fluid.

1. A fluid dispenser device comprising: a body (10) defining a dispensing orifice (11); a reservoir (20) containing one or more doses of fluid, said reservoir (20) having a piston (25) which, at rest, forms a leaktight stopper; a resilient element (30), such as a spring; an intermediate element (60) secured to said reservoir (20) or to said piston (25), said resilient element (30) co-operating firstly with said intermediate element (60) and secondly with a cocking member (40); and at least one triggering member (50, 51); said device being characterized in that said cocking member (40) co-operates with said body (10) in a rest position in which said resilient element (30) is not compressed, is mounted to be movable manually relative to said body (10) so as to compress said resilient element (30), and is mounted to be lockable relative to said body (10) in at least one locked position in which said resilient element (30) is compressed and in which said intermediate element (60) is locked relative to said body (10) in a locked position, said at least one triggering member (50, 51) co-operating with said intermediate element (60) so as to release it from its locked position so that said resilient element (30) moves said piston (25) relative to said reservoir (20) so as to expel a dose of fluid.
