Plastic aerosol container

摘要

An aerosol container includes a main body portion that is constructed and arranged to withstand aerosol pressurization within a range that is about 90-180 psig and a threaded finish portion that is unitary with the main body portion. The threaded finish portion has at least one helical thread, a support ledge beneath the helical thread and a secondary flange that is positioned beneath the support ledge. The secondary flange has an outer circumference that is noncircular in at least one location, whereby it may be engaged during a capping operation to prevent rotation of the container during capping. A method of making an aerosol container in which a preform is capped before the blow molding process is also disclosed.
