Abstract

A finish portion of a container preform for forming a plastic container includes an opening to an interior of the container preform and a stepped internal portion narrowing from the opening. One or more threads are disposed on an exterior of the finish portion for rotatably engaging a closure.

Claims (18)

CLAIMS:
1. A preform for forming a plastic container, the preform comprising: a stepped interior having a first sealing surface with a first diameter, a second sealing surface with a second diameter less than the first diameter, and a third sealing surface with a third diameter less than the second diameter; and one or more threads for rotatably engaging a closure.
2. The preform of claim 1 , wherein the first sealing surface and the second sealing surface are polished surfaces.
3. The preform of claim 2, wherein the third sealing surface is a polished surface.
4. The preform of claim 1, further including a transition surface joining the first sealing surface with the second sealing surface, wherein the transition surface includes a concave portion that extends from the first sealing surface and joins with a convex portion that extends to the second sealing surface.
5. The preform of claim 1, further including a transition surface joining the second sealing surface with the third sealing surface, wherein the transition surface includes a concave portion that extends from the second sealing surface and joins with a convex portion that extends to the third sealing surface.
6. A finish portion of a container preform for forming a plastic container, the finish portion comprising: an opening to an interior of the container preform; a stepped internal portion narrowing from the opening; and one or more threads disposed on an exterior of the finish portion for rotatably engaging a closure.
7. The finish portion of claim 6, wherein the stepped internal portion includes a sealing surface configured to cooperate with a plug seal of the closure.
8. The finish portion of claim 7, wherein the stepped internal portion includes a transition surface extending from the sealing surface to a handling surface having a diameter smaller than a diameter of the sealing surface.
9. The finish portion of claim 8, wherein the transition surface includes a concave portion that extends from the sealing surface and joins with a convex portion that extends to the handling surface.
10. The finish portion of claim 8, wherein the transition surface is configured to cooperate with a plug seal of the closure.
11. The finish portion of claim 8, wherein the handling surface is configured to cooperate with a plug seal of the closure.
12. The finish portion of claim 8, wherein the transition surface is a first transition surface, and wherein the stepped internal portion includes a second transition surface extending from the handling surface to an interior surface having a diameter smaller than the diameter of the handling surface.
13. The finish portion of claim 12, wherein the second transition surface includes a concave portion that extends from the handling surface and joins with a convex portion that extends to the interior surface.
14. The finish portion of claim 13, wherein the second transition surface is configured to cooperate with a plug seal of the closure.
15. The finish portion of claim 13, wherein the interior surface is configured to cooperate with a plug seal of the closure.
16. A container assembly comprising: a container having a finish portion with a graduated interior, the interior having a first sealing surface with a first diameter, a second sealing surface with a second diameter less than the first diameter, and a transition surface having a concave portion that extends from the first sealing surface and joins with a convex portion that extends to the second sealing surface; and a closure with a plug seal, the plug seal including a first seal configured to compressibly seal the first sealing surface and a second seal configured to compressibly seal the second sealing surface, the closure further configured to rotatably engage the finish portion.
17. The container assembly of claim 16, wherein the interior further includes a third sealing surface with a third diameter less than the second diameter, and wherein the plug seal includes a third seal configured to compressibly seal the third sealing surface.
18. The container assembly of claim 17, wherein transition surface is a first transition surface, and wherein the interior includes a second transition surface having a concave portion that extends from the second sealing surface and joins with a convex portion that extends to the third sealing surface.
