Dispenser for discharging pharmaceutical liquid, has accessible ratchet wheel which is rotated about rotational axis parallel to axial direction between blocking rotational position and operating rotational position

摘要

The dispenser (100) has a movable actuator (130) to deliver liquid from a liquid storage unit (120) to surrounding atmosphere through a discharge port. An accessible ratchet wheel is arranged externally in a housing (110). The ratchet wheel is rotated about a rotational axis parallel to an axial direction (2) between a blocking rotational position and an operating rotational position, where discharge of liquid is prevented in blocking position and discharge of liquid is allowed in operating position.
