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).
