Abstract

A dispensing package includes a container having a neck finish with an axis, a non-circular cross section in a plane perpendicular to the axis, and at least one circumferentially extending external engagement element on the neck finish. A closure has a wall received over the container neck finish. The wall has a non-circular cross section corresponding to the non-circular cross section of the neck finish and at least one internal circumferentially extending engagement element in engagement with the external engagement element on the neck finish. The internal circumferentially extending engagement element and/or the external circumferentially extending engagement element has a shallow lead-in angle to enable press-fit of the closure onto the container neck finish and a steep back angle to retard removal of the closure from the neck finish. Rotation of the closure on the neck finish is prevented by the non-circular cross sections of the neck finish and the closure wall.

Claims

1. A dispensing package that includes:

a container having a neck finish with an axis, a non-circular cross section in a plane perpendicular to said axis, and at least one external circumferentially extending engagement element, and

a closure having a wall received over said neck finish, said wall having a non-circular cross section corresponding to said non-circular cross section of said neck finish, and at least one internal circumferentially extending engagement element on said wall in engagement with said external circumferentially extending engagement elements on said neck finish,

said internal and/or said external circumferentially extending engagement elements having shallow lead-in angles to enable press-fit of said closure onto said container neck finish and steep back angles to retard removal of said closure from said neck finish,

rotation of said closure on said neck finish being prevented by said non-circular cross sections.

2. The package set forth in claim 1 wherein said at least one external circumferentially extending engagement element comprises a plurality of axially spaced external circumferentially extending engagement elements, and said at least one internal circumferentially extending engagement element comprises a plurality of axially spaced circumferentially extending engagement elements.

3. The package set forth in claim 2 wherein said closure includes a non-circular plug seal wall received within said neck finish, at least one of said engagement elements on said wall and at least one of said engagement elements on said neck finish being disposed radially outwardly from said plug seal wall.

4. The package set forth in claim 2 wherein said external engagement elements have said shallow lead-in angles and said steep back angles, and wherein said internal engagement elements have rounded profiles.

5. The package set forth in claim 4 wherein said shallow lead-in angles are about 40°

to said axis and said steep back angles are about 75°

to said axis.

6. The package set forth in claim 2 wherein said internal engagement elements on said wall and said external engagement elements on said neck finish are circumferentially continuous around said wall and said neck finish.

7. The package set forth in claim 2 wherein there are a plurality of axially spaced external engagement elements on said neck finish and a plurality of axially spaced internal engagement elements on said wall.

8. The package set forth in claim 1 wherein said closure includes a base on which said deck and said wall are disposed, a lid integrally hinged to said base and a child-resistant latch between said lid and said base.

9. A dispensing package that includes:

a container having a neck finish with an axis, a non-circular cross section in a plane perpendicular to said axis and a plurality of axially spaced circumferentially extending external engagement elements, and

a closure having a wall received over said neck finish, said wall having a non-circular cross section corresponding to said non-circular cross section of said neck finish, and a plurality of axially spaced circumferentially extending internal engagement elements on said wall in mating engagement with said external engagement elements on said neck finish,

said internal and/or said external circumferentially extending engagement elements having shallow lead-in angles to enable press-fit of said closure onto said neck finish and steep back angles to retard removal of said closure from said neck finish,

rotation of said closure on said neck finish being prevented by said non-circular cross sections.

10. The package set forth in claim 9 wherein said closure includes a non-circular plug seal wall received within said neck finish, at least one of said engagement elements on said wall and at least one of said engagement elements on said neck finish being disposed radially outwardly from said plug-seal wall.

11. The package set forth in claim 10 wherein said external engagement elements have said shallow lead-in angles and said steep back angles and said internal engagement elements have rounded profiles.

12. The package set forth in claim 11 wherein said internal engagement elements on said wall and said external engagement elements on said neck finish are circumferentially continuous around said wall and said neck finish.

13. The package set forth in claim 12 wherein said closure includes a base on which said deck and said wall are disposed, a lid integrally hinged to said base and a child-resistant latch between said lid and said base.

14. A container having a neck finish with an axis, a non-circular cross section in a plane perpendicular to said axis, and a plurality of axially spaced circumferentially extending engagement elements on said neck finish, said circumferentially extending engagement elements having shallow lead-in angles to enable press-fit of a closure onto said neck finish and steep back angles to retard removal of the closure from said neck finish.

15. The container set forth in claim 14 wherein said shallow lead-in angles are about 40°

to said axis and said steep back angles are about 75°

to said axis.

16. The container set forth in claim 14 wherein said external engagement elements are circumferentially continuous around said neck finish.

17. A closure having a wall for receipt over a neck finish on a container to secure the closure to the container, said wall having an axis and a non-circular cross section perpendicular to said axis, a plurality of circumferentially extending axially spaced rounded internal engagement elements on said wall, and a non-circular plug seal wall for receipt within the container neck finish, at least one of said engagement elements being disposed radially outwardly from said plug-seal wall.

18. The closure set forth in claim 17 wherein said rounded internal engagement elements on said wall are circumferentially continuous around said wall.

19. The closure set forth in claim 17 wherein said closure includes a base on which said deck and said wall are disposed, a lid integrally hinged to said base and a child-resistant latch between said lid and said base.
