Abstract
A metering valve has an elongate axially moveable stem having a discharge passage. A flexible bag for containing a formulation to be discharged surrounds the lower end of the metering valve. The valve is fillable through a fill passage having one end opening to the ambient and the other end opening into the bag. A one-way valve in the fill passage prevents liquid in the bag from escaping through the fill passage but allows the bag to be filled after the lower end of the valve and the bag are inserted into a container and the container pressurized with a propellant.
