Abstract
A pressurized container includes a dispenser which releases liquid contents from the container into the atmosphere in the form of an aerosol spray by way of a discharge nozzle. Additional gas is injected into the dispenser under pressure and discharged with the spray to enhance the finely divided nature of the spray particles and to render more uniform the rate of discharge of the liquid contents as emptying of the container takes place. The container for the liquid product may be pressurized by a non-liquefied gas, for example carbon dioxide gas, and the additional gas may be supplied from a container of liquefied additional gas or a container of additional gas dissolved in a solvent medium.
