ABSTRACT:
A valve for an aerosol container, of the kind which is adapted to pass propellant into the container to pressurize the aerosol product, has a dip tube which is arranged to act as a diffuser. The propellant is thereby caused to enter the product as a large number of small bubbles rather than a much smaller number of larger bubbles. By thus improving the rate of solution of the propellant in the product the propellant charging times can be substantially reduced.
