A dispenser brush for dispensing doses of an agent comprises a brush head (1), a conduit member (3) and a piston pump (4) placed between the reservoir and the dispensing openings. To obtain a very precise dosing the piston pump (4) is arranged for movement in a direction substantially normal to the longitudinal axis of the brush. The actuator button (11) of the piston may be activated by the thumb of the user while having a normal working grip around the handle. |
