ABSTRACT:
The present valve for a spray container has a mixing chamber for mixing a gas propellant with the active ingredient for producing a finely atomized spray. The gas propellant enters into the valve housing by means of sufficient clearance between the walls of the valve body and the valve housing. The active ingredient and the gas propellant both enter into a mixing chamber through simultaneously openable and closable passage openings. The valve stem of the present valve has two channels. One channel in the valve stem provides a flow path for the gas propellant and for the active ingredient mixture, the other channel in the stem providing a flow path substantially for the gas propellant alone. These channels combine in a second mixing chamber resulting in still further atomization of the spray and a more efficient utilization of substantially the entire container content.
