A low pressure aerosol dispensing can which is distinguished from existing high pressure aerosol dispensing cans. The generally cylindrical can has a thin wall thickness, like that of a carbonated beverage can, which can be distorted by finger pressure but whose shape is maintained by internal gas pressure. The liquid contents to be dispensed and the propellant gas are mixed in the can. The dispensing valve at the top of the can dispenses the liquid contents and propellant in a controlled manner. The valve may include an additional narrow bore vapor tap between the gaseous propellant head space in the can and the valve chamber for delivering extra gas for atomizing the liquid and propelling it from the nozzle. The gas pressure in the can is coordinated with the can wall and bottom thickness so that the can will have sufficient distortion resistance and burst resistance at elevated temperature. Yet the can has side walls of a thickness low enough to permit the can to be easily crushed by hand pressure when the can is empty.

[ What is claimed is:] [20.] A low pressure, non-barrier type, aerosol spray valved dispensing can for containing and dispensing fluent materials in aerosol spray form by compressed and/or liquified gas the can comprising:a generally cylindrical can having a wall of such a material and with such a thickness that when the can is unpressurized, the can wall is easily distortable by normal finger pressure and is easily crushable by normal hand pressure, but when the can is pressurized, the can is rigid enough to not be easily distortable and crushable by normal finger and hand pressure;the can being adapted for containing propellant and fluent material to be dispensed, the propellant and fluent material not be separated by a barrier in the can between them;an aerosol spray dispensing valve on the can with a valve orifice adapted to be opened to dispense a desired quantity and rate of flow of fluent material and propellant in an aerosol spray form and in a manner such that the can will retain enough propellant pressure to expel substantially all of the dispensable fluent material in the can. .Iaddend..Iadd.
