ABSTRACT:
A valve for aerosol container to dispense a given amount of aerosol from an associated aerosol tank, comprising a base solid providing a valve chamber and a valve stem slidably fitted and upwardly biased by a spring in the chamber. An inlet is made on the bottom of the chamber thereby permitting injection of aerosol from the associated aerosol tank. The valve stem provides a longitudinal channel and an outlet communicating the channel with the valve chamber, and a valve head fixed to the bottom end. A valve ring fitted at the upper side of the chamber in air-tight fashion shutting the outlet all the time. Whereby on depression of the valve stem, the valve ring is yieldingly bent for opening the outlet of the valve stem, thereby allowing a predetermined amount of aerosol to flow out of the valve chamber and eject from the longitudinal channel of the valve stem while shutting the inlet on the bottom of the chamber with the valve head of the valve stem.
