Abstract
A metering valve having an elongate moveable stem arranged for axial movements within a container and defining a discharge passage. A flexible bag for containing a liquid formulation to be dispensed from the metering valve surrounds a lower end of the metering valve. The bag is fillable through a fill passage defined by the valve and from an exterior of the container. A one-way valve, disposed in operable combination with the fill passage, prevents liquid formulation in the bag from escaping to ambient through the fill passage but allows the bag to be filled after the lower end of the valve and the bag are inserted into the container and the container is pressurized with a propellant.
