Abstract
A plastic aerosol container includes a main body portion that is constructed and arranged to withstand aerosol pressurization within a range that is about 50-300 psig. The plastic aerosol container also includes a finish portion that is unitary with the main body portion. The finish portion may be threaded or unthreaded. The finish portion has a side wall, an upper sealing surface, at least one helical thread and a support ledge beneath the helical thread. Reinforcement structure is positioned beneath the support ledge for reinforcing the finish portion against deformation due to the pressurization. A method of stabilizing a plastic aerosol container is also disclosed.
