Abstract: A dual dispenser having two pumps (P1, P2) associated with two reservoirs, each pump having a pump body (P10, P20) and an actuator rod (P11, P21) axially movable over an axial stroke; and a dispenser head including a dispenser orifice (O) for dispensing the fluids coming from the actuator rods (P11, P21). The dispenser head has a cap (1) mounted on the actuator rods (P11, P21) and that forms the dispenser orifice (O); a pusher (2) mounted on the cap (1) so as to move it axially downwards and upwards, the pusher (2) also being mounted on the cap (1) so as to turn relative thereto; and an adjustment insert (3) arranged below the cap (1) and that is secured to the pusher (2) to turn with it, the cap (1) coming into abutment against the adjustment insert (3), limiting the axial stroke of the actuator rods (P11, P21).

Abstract: A fastener ring for mounting a dispenser member, such as a pump or a valve, on a neck of a reservoir so as to constitute a fluid dispenser, the ring having a reception device suitable for receiving, in stationary manner, the dispenser member; and a fastener suitable for coming into engagement with the neck. A rupture device is provided between the reception device and the fastener so as to separate the reception device from the fastener, in such a manner as to be able to remove the dispenser member from the reservoir.
