Abstract
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).
