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.
Claims31
A plastic aerosol container, comprising:
- a main body portion that is constructed and arranged to withstand aerosol pressurization within a range that is about 50-300 psig;
- and
- a finish portion that is unitary with the main body portion and defines a vertical longitudinal axis, the finish portion having a side wall, an upper sealing surface, a securement structure extending outwardly from the side wall, a support ledge separate from and beneath the securement structure, and a reinforcement structure separate from and beneath the support ledge for reinforcing the finish portion against deformation due to the pressurization;
- wherein the support ledge defines an outer circumference that is noncircular in at least one location;
- and
- wherein the support ledge defines a horizontal planar upper surface about a circumference of the finish portion.
