Abstract

A container includes a neck finish extending from a body and having at least two thickened wall portions circumferentially spaced apart and extending radially inwardly, and including interior surfaces disposed radially inwardly of a neck finish interior surface to at least partially establish an internal trough, and axially facing shoulders axially recessed with respect to a sealing lip of the neck finish.

First claim

The invention claimed is:

1. A method of making a container that includes the steps of:
forming a parison in a blank mold wherein the parison includes a body and a neck finish, and the neck finish includes a neck finish interior, a sealing surface facing generally axially and extending fully circumferentially continuously around the neck finish interior, and at least one axially facing shoulder, wherein the forming step comprises:
forming, by a plunger of the blank mold, a first portion of the neck finish interior to have a first geometry with at least two thickened wall portions circumferentially spaced apart, and extending radially inwardly and chordally with respect to the neck finish, wherein the thickened wall portions included interior surfaces to at least partially establish an internal trough, the plunger having a non-circular cross-section to form the first portion of the neck finish interior with a corresponding non-circular cross-section; and
forming, by one of the plunger and a guide ring of the blank mold, a second portion of the neck finish interior to have a second geometry different than the first geometry and that includes the at least one axially facing shoulder being axially recessed with respect to the axially facing sealing surface; and

blowing the parison in a blow mold to form the container, which has the neck finish having the axially facing sealing surface extending fully circumferentially around the neck finish interior and the neck finish interior having the at least one axially facing shoulder axially recessed with respect to the axially facing sealing surface.

2. The method of claim 1 , wherein the forming step comprises forming, by the guide ring, the axially facing sealing surface.

3. The method of claim 1 , wherein the first and second portions of the neck finish interior are formed by pressing the parison against the plunger of the blank mold and one of the plunger and the guide ring of the blank mold, respectively, as a pressing step in a press-and-blow process.

4. The method of claim 1 , wherein the first and second portions of the neck finish interior are formed by blowing the parison against the plunger of the blank mold and one of the plunger and the guide ring of the blank mold, respectively, as a first blowing step in a blow-and-blow process.

5. The method of claim 1 , wherein the neck finish also includes a fully circumferentially continuously extending step-down axially recessed with respect to the axially facing sealing surface and coplanar with the at least one axially facing shoulder.

6. The method of claim 1 , wherein the neck finish also includes closure engagement features extending completely circumferentially around an outer surface of the neck finish.

7. A method of making a container that includes the steps of:
forming a parison in a blank mold wherein the parison includes a body and a neck finish, and the neck finish includes a neck finish interior, a sealing surface facing generally axially and extending fully circumferentially continuously around the neck finish interior, and a pair of axially facing shoulders, wherein the forming step comprises:
forming, by a plunger of the blank mold, a first portion of the neck finish interior to have a first geometry; and
forming, by a guide ring of the blank mold, a second portion of the neck finish interior to have a second geometry different than the first geometry and that includes the pair of axially facing shoulders being axially recessed with respect to the axially facing sealing surface; and

blowing the parison in a blow mold to form the container, which has the neck finish having the axially facing sealing surface extending fully circumferentially around the neck finish interior and the neck finish interior having the pair of axially facing shoulders axially recessed with respect to the axially facing sealing surface.

8. The method of claim 7 , wherein the plunger forms the first portion of the neck finish interior to have at least two thickened wall portions circumferentially spaced apart and extending radially inwardly and chordally with respect to the neck finish.

9. The method of claim 8 , wherein the at least two thickened wall portions include interior surfaces to at least partially establish an internal trough.

10. The method of claim 7 , wherein the forming step comprises forming, by the guide ring of the blank mold, the axially facing sealing surface.

11. The method of claim 7 , wherein the plunger has a non-circular cross-section to form the first portion of the neck finish interior with a corresponding non-circular cross-section.

12. The method of claim 7 , wherein the first and second portions of the neck finish interior are formed by pressing the parison against the plunger of the blank mold and the guide ring of the blank mold, respectively, as a pressing step in a press-and-blow process.

13. The method of claim 7 , wherein first and second portions of the neck finish interior are formed by blowing the parison against the plunger of the blank mold and the guide ring of the blank mold, respectively, as a first blowing step in a blow-and-blow process.

14. The method of claim 9 , wherein the neck finish also includes a fully circumferentially continuously extending step-down axially recessed with respect to the axially facing sealing surface and coplanar with the at least one axially facing shoulder.

15. The method of claim 7 , wherein the neck finish also includes closure engagement features extending completely circumferentially around an outer surface of the neck finish.

16. A method of making a container that includes the steps of:
forming a parison in a blank mold wherein the parison includes a body and a neck finish, and the neck finish includes a neck finish interior, a sealing surface facing generally axially and extending fully circumferentially continuously around the neck finish interior, and at least one axially facing shoulder, wherein the forming step comprises:
forming, by a plunger of the blank mold, a first portion of the neck finish interior to have a first geometry with at least two thickened wall portions circumferentially spaced apart, and extending radially inwardly and chordally with respect to the neck finish, wherein the thickened wall portions included interior surfaces to at least partially establish an internal trough, the plunger having a non-circular cross-section to form the first portion of the neck finish interior with a corresponding non-circular cross-section; and
forming, by the plunger, a second portion of the neck finish interior to have a second geometry different than the first geometry and that includes the at least one axially facing shoulder being axially recessed with respect to the axially facing sealing surface; and

blowing the parison in a blow mold to form the container, which has the neck finish having the axially facing sealing surface extending fully circumferentially around the neck finish interior and the neck finish interior having the at least one axially facing shoulder axially recessed with respect to the axially facing sealing surface.

17. The method of claim 16 , wherein the first and second portions of the neck finish interior are formed by pressing the parison against the plunger of the blank mold as a pressing step in a press-and-blow process.

18. The method of claim 16 , wherein the first and second portions of the neck finish interior are formed by blowing the parison against the plunger of the blank mold, as a first blowing step in a blow-and-blow process.
