ABSTRACT:
A supply of a propellant gas is maintained at substantially uniform temperature and pressure. Uniform predetermined increments of the propellant gas are withdrawn in rapid succession and rapidly introduced into aerosol containers in which product to be dispensed has already been introduced. Such containers are subjected to ultrasonic frequency agitation during the introduction of the propellant thereby enhancing the speed of introduction. The propellant may be introduced into a container either by the "through-the-valve" method or by the "under-the-cap" method at conventional speeds using known commercial equipment.
