Abstract
An aerosol type dispenser, wherein a dispensable fluid product is in storage, under pressure, intermediate wall surfaces of the dispenser and exterior surfaces of a pliable, impervious, expandable sac. Propellant gas, contained in isolation within the confinements of the sac, influence expansible surfaces of the sac to exert an expulsion force to the product. A dispensing valve mechanism, of choice, is utilized for the appropriate dispensing application. Propellant vapors may be co-dispensed with the product to provide an atomized spray or the vapors can be used to remove product residue from the valve mechanism.
