Abstract
An aerosol type dispensing package utilizing CO.sub.2 as a propellant has a container with a dispensing valve having a passage extending longitudinally through the nozzle thereof and at least one lateral passage opening into the longitudinal passage. Separate flow paths extend from obturator means in the valve to the central passage and to the lateral passage. The obturator means obturates a main flow path from a dip tube and is movable to the open position upon actuating of the valve. The dip tube extends from the valve means to near the bottom of the container and is in communication with the main flow path. A body of a solution of a product to be dispensed in a liquid in which CO.sub.2 can be dissolved fills the container to a level below the top of the container for leaving a gas space in the upper part of the container. Compressed carbon dioxide is present in the space in the container above the body of solution.
