Abstract

A metering valve for a pressurized dispensing container. The container is intended to operate in the inverted position. An element having a raised peripheral portion is provided about the valve housing which substantially closes the space between the wall of the container and the valve housing. The element prevents the settling of active substances of the material being dispensed in the region of the inlet opening of the metering valve.
