Abstract
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.
