Claims
- 1. A pressurized fluid package comprising
- an oriented plastic container including a cylindrical side wall, a neck, a neck finish on the upper end of the neck for receiving a closure, and a hemispherical bottom wall,
- a plastic base including an annular seating area for engaging a surface on which the package is supported,
- said base having a peripheral annular inverted frustoconical wall extending upwardly and outwardly and terminating in an annular frustoconical free edge portion defining an inner primary support area tangentially engaging a complementary area of the upper end of the hemispherical wall of the container to provide primary support axially for the container in the base,
- said hemispherical bottom wall having a radius that is uniform throughout the bottom wall,
- said free edge portion of said frustoconical wall engaging the hemispherical wall and being tangential thereto at an angle ranging between 50.degree. and 75.degree. with a transverse plane through the axis of the base,
- said base having a second contact area for receiving adhesive to bond the hemispherical bottom wall of the container.
- 2. The pressurized fluid package set forth in claim 1 wherein said container has a central axially upwardly extending recess, said base having a cruciform projection extending axially upwardly into and engaging said recess.
- 3. The pressurized fluid package set forth in claim 1 wherein said second contact area is centrally located in the bottom of said base.
- 4. The pressurized fluid package set forth in claim 1 wherein said second contact area comprises an annular portion tangential to portions of the hemispherical wall of the container.
- 5. The pressurized fluid package set forth in claim 4 wherein said container has a central axially upwardly extending recess, said base having a cruciform projection extending axially upwardly into and engaging said recess.
- 6. The pressurized fluid package set forth in claim 1 wherein said container comprises a one-half liter container and the angle ranges between 54.degree. and 65.degree..
- 7. The pressurized fluid package set forth in claim 1 wherein said container comprises a one liter container and the angle ranges between 59.degree.-65.5.degree..
- 8. The pressurized fluid package set forth in claim 1 wherein said container comprises a two liter container and the angle ranges between 58.degree.-65.degree..
- 9. The pressurized fluid package set forth in claim 1 wherein said container comprises a one gallon container and the angle ranges between 62.5.degree.-70.degree..
- 10. A base for an oriented plastic container including a cylindrical side wall, a neck finish on the upper end of the neck for receiving a closure, and a hemispherical bottom wall having a radius that is uniform throughout the bottom wall,
- said base being made of plastic and including an annular seating area for engaging a surface on which the package is supported,
- said base having a peripheral annular inverted frustoconical wall extending upwardly and outwardly and terminating in an annular frustoconical free edge portion defining an inner primary support area tangentially engaging a complementary area of the upper end of the hemispherical wall of a container to provide primary support axially for the container in the base,
- said free edge of said frustoconical wall adapted to engage the hemispherical wall and be tangential thereto at an angle ranging between 50.degree. and 75.degree. with a transverse plane through the axis of the base,
- said base having a second contact area for receiving adhesive to bond the hemispherical bottom wall of a container.
- 11. The base set forth in claim 10 wherein said base has a cruciform projection extending axially upwardly and adapted to extend into and engage a central axially extending recess in a container.
- 12. The base set forth in claim 10 wherein said second contact area is centrally located in the bottom of said base.
- 13. The base set forth in claim 10 wherein said second contact area comprises an annular portion tangential to portions of the hemispherical wall of a container.
- 14. The base set forth in claim 13 wherein said base has a cruciform projection extending axially upwardly and adapted to extend into and engage a central axially extending recess in a container.
- 15. The base set forth in claim 10 wherein the angle ranges between 54.degree. and 65.degree..
- 16. The base set forth in claim 10 wherein the angle ranges between 59.degree.-65.5.degree..
- 17. The base set forth in claim 10 wherein the angle ranges between 58.degree.-65.degree..
- 18. The base set forth in claim 10 wherein the angle ranges between 62.5.degree.-70.degree..
