A dispenser head comprising a connection sleeve ( 20 ), a dispenser orifice ( 31 ), a duct ( 123 ) connecting said connection sleeve ( 20 ) to the dispenser orifice, and a press surface ( 11 ), the head further comprising a shutter ( 4 ) that is housed, at least in part, in said duct ( 123 ), and that is resiliently biased by spring means ( 47 ) towards said dispenser orifice ( 31 ), said shutter ( 4 ) including a contact zone ( 41 ) that bears in resilient leaktight manner against the dispenser orifice ( 31 ) so as to seal it hermetically, said shutter being axially movable against the spring means in such a manner as to withdraw its contact zone from the dispenser orifice, thereby creating an outlet passage for the fluid, the shutter including at least one abutment zone ( 440 ) that is resiliently biased by the spring means against a fixed support zone ( 34 ).
