A large size aerosol container (10') dispensing a fluent material. A generally cylindrical can body (12') is fabricated from a steel sheet and has a relatively thin sidewall thickness of between 0.004 inches and 0.010 inches depending upon the weight of the steel sheet from which the container is made. The can body has beads (30) formed at regular intervals substantially its length. The beading adds structural strength to the container so the container is not damaged by handling during manufacture of the container, will not collapse during vacuum filling, and cannot be crushed by hand before the container is filled. The container can withstand a vacuum of at least 23 inches of Mercury without collapsing. A valve assembly (14') includes a spray valve (20) for dispensing the fluent material stored in the container. The container is filled with the fluent material and a propellant stored in the container under pressure.
