Abstract: A fluid dispenser member for associating with a fluid reservoir (3). The member has a body (1), a fastener ring (2) for holding the body in stationary manner relative to the reservoir (3), a covering hoop (6) that is engaged in stationary manner around the fastener ring (2), an actuator rod (15) that is axially movable down and up in the body (1), and a pusher (4) that is mounted on the actuator rod (15). The pusher is provided with a dispenser orifice (44). The dispenser member is provided with a blocking mechanism (49, 5, 62) that is secured to the hoop so as to prevent the pusher from turning on the actuator rod relative to the body, and consequently relative to the reservoir, such that the pusher is movable only axially. The blocking mechanism includes at least one longitudinal axial guide (55).
