Abstract

A molded, pressure capable container (50) is provided for use with an aerosol valve assembly (12A) to dispense a fluent product stored in the container (50). The aerosol valve assembly (12A) includes an aerosol valve (24) and a mounting cup (23A) that is crimped onto the container (50) to mount the aerosol valve (24) to the container (50). The container (50) includes a molded body (52) having a chamber (54) to contain a fluent product, a dispensing opening (56) extending from the chamber (54) to an exterior of the container (50), and a neck finish area (57) in the form of an annular neck (58) surrounding the opening (56) and an annular neck flange (60) on a distal end of the annular neck (58) to mount the aerosol valve assembly (12A). The neck flange (60) is defined by a radially outermost, annular edge (62); an annular end surface (64) extending from the annular edge (62) to the opening (56); and a frustoconical-shaped surface (66) extending from the annular edge (62) to an outer surface (68) of the annular neck (58).

Claims (15)

1. A molded, pressure capable container (50) for use with an aerosol valve assembly (12A) to dispense a fluent product stored in the container (50), the aerosol valve assembly (12A) including an aerosol valve (24) and a mounting cup (23A) that is crimped onto the container (50) to mount the aerosol valve (24) to the container (50), the container (50) comprising:
a molded body (52) having a chamber (54) to contain a fluent product, a dispensing opening (56) extending from the chamber (54) to an exterior of the container (50), an annular neck (58) surrounding the opening (56), and an annular neck flange (60) on a distal end of the annular neck (58) to mount the aerosol valve assembly (12A), the neck flange (60) being configured for crimping of the mounting cup (23A) thereto and being defined by a radially outermost, annular edge (62);
an annular end surface (64) extending from the annular edge (62) to the opening (56); and a frustoconical-shaped surface (66) extending from the annular edge (62) to an outer surface (68) of the annular neck (58), wherein the annular edge (62) and the frustoconical-shaped surface (66) are engageable with the mounting cup (23A) upon crimping of the mounting cup (23A) to the annular neck flange (60).
2. The container (50) of claim 1 wherein the annular neck flange (60) has a radial thickness Tr from the annular edge (62) to the opening (56), and the annular edge (62) has axial thickness Ta transverse to the radial thickness Tr, and the ratio of radial thickness Tr to the axial thickness Ta is no less than 3.0/1Ø

6. The container (50) of claim 5 wherein the angle .alpha. is in the range of 55° to 65°.
7. The container (50) of claim 5 wherein the angle .alpha. is 60°.
8. The container (50) of claim 1 wherein the annular edge (62) is centered on a central, longitudinal axis (70), has an axial thickness Ta parallel to the axis (70), and is blended to the end surface with a blend radius R that is no greater than 60% of the thickness Ta.
9. The container (50) of claim 8 wherein the blend radius R is no greater than 50% of the thickness Ta.
10. The container (50) of claim 1 wherein the annular edge (62) is centered on a central, longitudinal axis (70), has an axial thickness Ta parallel to the axis (70), and is blended to the frustoconical-shaped surface (66) with a blend radius R that is no greater than 60% of the thickness Ta.
11. The container (50) of claim 10 wherein the blend radius R in no greater than 50% of the thickness Ta.
12. The container (50) of claim 1 in combination with an aerosol valve assembly (12A), the aerosol valve assembly comprising an aerosol valve (24) and a mounting cup (23A), the mounting cup (23A) formed from a material having a thickness Tm, the mounting cup (23A) being crimped to the annular neck flange (60).
13. The container (50) of claim 12 wherein the annular edge (62) is centered on a central, longitudinal axis (70) and has. an axial thickness Ta parallel to the axis (70) that is no greater than 4.0 x Tm.
14. The container (50) of claim 13 wherein Ta is no greater than 3.5 x Tm.
15. The container (50) of claim 12 wherein the annular edge (62) is blended to the annular end surface (64) and the frustoconical-shaped surface (66) with blend radiuses R that are no greater than 2.1333 x Tm.
