Abstract
A plastic aerosol container includes a plastic base portion and a plastic main body portion that is unitary with the plastic base portion and defines a longitudinal axis. The base portion and the main body portion together define an internal space within the container that is pressurized with an aerosol mixture at a pressure that is substantially within a range of about 50 psi to about 300 psi at room temperature. The main body portion has an upper portion that has a first maximum transverse diameter, a lower portion that has a second maximum transverse diameter and an intermediate portion that has a third maximum transverse diameter. The third minimum transverse diameter is less than both the first and second maximum transverse diameters, whereby the main body portion has a narrowed waist portion that provides reinforcement against deformation as a result of pressurization within the internal space of the container. The narrowed waist portion preferably has a substantially constant radius of curvature.
