Abstract
An aerosol type dispenser has a plurality of sources of fluent materials to be dispensed and a source of propellant gas under pressure exerting pressure on the fluent materials. The sources of fluent material is a rigid container holding one fluent material and a further collapsible container within the rigid container holding a second fluent material, and the source of propellant gas is a mass of compressed propellant gas in the container above the one fluent material and at least partially surrounding the second container. A valve member on the container has fluent material flow path means forming a path for pressurized fluent material through the valve member from the sources of fluent material, and the valve member further has a pressurized gas, i.e. propellant, flow path therethrough from the source of propellant gas. The valve member has an obturating member actuated by the movement of a valve stem for obturating the flow paths. A dispensing nozzle is provided having a pressurized fluent material passage directed out of the dispensing nozzle, and having a pressurized gas passage intercepting the fluent material passage at substantially right angles thereto just ahead of the discharge outlet from the nozzle.
