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.

1. 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; anda 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; andwherein the support ledge defines a horizontal planar upper surface about a circumference of the finish portion. 2. The plastic aerosol container of claim 1, wherein the reinforcement structure comprises a flange that is unitary with the side wall of the finish portion. 3. The plastic aerosol container of claim 2, wherein the flange is injection molded. 4. The plastic aerosol container of claim 1, wherein the reinforcement structure is blow molded. 5. The plastic aerosol container of claim 1, further comprising an aerosol dispensing closure mounted to the finish portion. 6. The plastic aerosol container of claim 5, wherein the aerosol dispensing closure is secured to the finish portion with the securement structure. 7. The plastic aerosol container of claim 1, wherein the securement structure and the main body portion are fabricated from polyethylene terephthalate. 8. The plastic aerosol container of claim 1, wherein a space is defined between the support ledge and the reinforcement structure, and wherein the space has a minimum vertical dimension that is at least about 1 mm. 9. The plastic aerosol container of claim 1, wherein a space is defined between the support ledge and the reinforcement structure, and wherein the space has a minimum vertical dimension that is at least about 1.5 mm. 10. The plastic aerosol container of claim 1, wherein the main body portion is constructed of polyethylene terephthalate. 11. The plastic aerosol container of claim 1, wherein the main body portion is constructed of plastic. 12. The plastic aerosol container of claim 1, wherein the finish portion and main body portion are fabricated from a material comprising at least one of the following: polyethylene terephthalate, polyethylene naphthalate, acrylonitrile, polycarbonate, polyamide, or a blend thereof. 13. The plastic aerosol container of claim 12, wherein the material has a viscosity ranging from about 0.76 to about 0.95. 14. The plastic aerosol container of claim 1, wherein the container has a wall thickness in the range from about 0.018 inch to about 0.022 inch. 15. The plastic aerosol container of claim 1, wherein the securement structure comprises a threaded portion. 16. The plastic aerosol container of claim 1, further comprising an aerosol mixture within the container. 17. 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; anda 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 comprises at least one position-registering recess defined therein; andwherein the support ledge defines a horizontal planar upper surface about a circumference of the finish portion. 18. The plastic aerosol container of claim 17, wherein the reinforcement structure comprises a flange that is unitary with the side wall of the finish portion. 19. The plastic aerosol container of claim 18, wherein the flange is injection molded. 20. The plastic aerosol container of claim 17, wherein the reinforcement structure is blow molded. 21. The plastic aerosol container of claim 17, wherein an aerosol dispensing closure is secured to the finish portion with the securement structure. 22. The plastic aerosol container of claim 17, wherein the securement structure and the main body portion are fabricated from polyethylene terephthalate. 23. The plastic aerosol container of claim 17, wherein a space is defined between the support ledge and the reinforcement structure, and wherein the space has a minimum vertical dimension that is at least about 1 mm. 24. The plastic aerosol container of claim 17, wherein a space is defined between the support ledge and the reinforcement structure, and wherein the space has a minimum vertical dimension that is at least about 1.5 mm. 25. The plastic aerosol container of claim 17, wherein the main body portion is constructed of polyethylene terephthalate. 26. The plastic aerosol container of claim 17, wherein the main body portion is constructed of plastic. 27. The plastic aerosol container of claim 17, wherein the finish portion and main body portion are fabricated from a material comprising at least one of the following: polyethylene terephthalate, polyethylene naphthalate, acrylonitrile, polycarbonate, polyamide, or a blend thereof. 28. The plastic aerosol container of claim 27, wherein the material has a viscosity ranging from about 0.76 to about 0.95. 29. The plastic aerosol container of claim 17, wherein the container has a wall thickness in the range from about 0.018 inch to about 0.022 inch. 30. The plastic aerosol container of claim 17, wherein the securement structure comprises a threaded portion. 31. The plastic aerosol container of claim 17, further comprising an aerosol mixture within the container.
