The invention describes a squeeze bottle for dispensing a liquid, in particular a liquid medicament, in a metered and substantially germ-free manner, at least comprising: a storage chamber for accommodating the liquid, a metering chamber with a variable volume for dispending from this chamber, under reduction of volume of the chamber, a measured volume of liquid, restoring means for returning the metering chamber to its original state after a volume of liquid has been dispensed, an inlet for placing the metering chamber in communication with the storage chamber by mediation of a flow restrictor, which flow restrictor counteracts flow from the metering chamber to the storage chamber substantially completely when the pressure in the storage chamber is increased, counteracts flow between the storage chamber and the metering chamber substantially completely and , when the increase pressure in the storage chamber is removed, allows flow from the storage chamber into the metering chamber, at least one outflow opening for placing the interior of the metering chamber in communication with the environment, the outflow opening comprising a non-return valve, actuating means can be actuated by squeezing the bottle, means for ventilating the squeeze bottle.

1. Squeeze bottle (1) for dispensing a liquid, in particular a liquid medicament, in a metered and substantially germ-free manner, at least comprising:a storage chamber (2) for accommodating the liquid, a metering chamber (3) with a variable volume for dispensing from this chamber, under reduction of volume of the chamber, a measured volume of liquid, restoring means (8) for returning the metering chamber to its original state after a volume of liquid has been dispensed, an inlet (4) for placing the metering chamber in communication with the storage chamber by mediation of a flow restrictor, which flow restrictor counteracts flow from the metering chamber to the storage chamber substantially completely and, when the pressure in the storage chamber is increased, counteracts flow between the storage chamber and the metering chamber substantially completely and, when the increased pressure in the storage chamber is removed, allows flow from the storage chamber into the metering chamber, at least one outflow opening (5) for placing the interior of the metering chamber in communication with the environment, the outflow opening comprising a non-return valve (6), which exclusively allows flow in the intended dispense direction, the valve being designed in such a way that valve portions that are, in closed position, in direct contact with the environment, are also located outside the metering chamber in opened position of the valve, and valve portions that are, in opened position, in direct contact with the environment, are also located outside the metering chamber in closed position of the valve, actuating means (7) for reducing the volume of the metering chamber, which actuating means can be actuated by squeezing the bottle, means for ventilating the squeeze bottle.
