ABSTRACT:
Aerosol package employs a compressed gas such as carbon dioxide or nitrous oxide as propellant and provides a tiny vapor tap in the aerosol valve body to permit, in a restricted controlled way, the passage of the propellant gas into the aerosol valve. The diameter of the vapor tap is preferably in the range of only about 0.004" to only about 0.008". In a modification a pair of vapor tap openings of 0.006" diameter are formed in the valve. This permits a lesser initial can pressure.
