Abstract

A nozzle for a blow-molding process includes a first sealing portion and a second seating portion. A transition portion is positioned between the first sealing portion and the second sealing portion. The nozzle is configured such that upon engagement with a container preform having a longitudinal axis, the second sealing portion is positioned along the longitudinal axis at a different location than the first sealing portion.

First claim

What is claimed is:

1 . A nozzle for a blow-molding process, the nozzle comprising:
a first sealing portion; a second sealing portion; and a transition portion positioned between the first sealing portion and the second sealing portion, the nozzle configured such that upon engagement with a container preform having a longitudinal axis, the second sealing portion is positioned along the longitudinal axis at a different location than the first sealing portion.

2 . The nozzle of claim 1 , wherein a seal of the first sealing portion is disposed around a circumference of the first sealing portion.

3 . The nozzle of claim 2 , wherein the seal of the first sealing portion is in the form of an O-ring.

4 . The nozzle of claim 1 , wherein a seal of the second sealing portion is disposed around a circumference of the second sealing portion.

5 . The nozzle of claim 4 , wherein the seal of the second sealing portion is in the form of an O-ring.

6 . The nozzle of claim 1 , wherein one of the first and second sealing portions includes a circular edge as a seal.

7 . The nozzle of claim 6 , wherein the circular edge is a blunt circular edge.

8 . The nozzle of claim 1 , wherein the nozzle further defines an opening configured to permit the insertion of a blow-molding instrument therethrough.

9 . The nozzle of claim 1 , wherein the first and second sealing portions are cylindrical, and wherein the second sealing portion has a larger outer diameter than the first sealing portion.

10 . A nozzle for a blow-molding process, the nozzle comprising:
a first sealing portion; and a second sealing portion, the nozzle configured such that upon engagement with a container preform having a sealing surface disposed on an interior of the preform finish adjacent a preform opening, no portion of the nozzle contacts the sealing surface.

11 . The nozzle of claim 10 , further including a transition connecting the first sealing portion with the second sealing portion.

12 . The nozzle of claim 10 , wherein the second sealing portion is a tapered sealing portion.

13 . The nozzle of claim 12 , wherein a seal of the second sealing portion is disposed around a circumference of the second sealing portion.

14 . The nozzle of claim 10 , wherein the nozzle further defines an opening configured to permit the insertion of a blow-molding instrument therethrough.

15 . The nozzle of claim 10 , wherein the first and second sealing portions are cylindrical, and wherein the second sealing portion has a larger outer diameter than the first sealing portion.

16 . A nozzle for a blow-molding process, the nozzle comprising:
a first cylindrical portion with a first seal; a second portion with second seal, wherein the second portion is one of a cylindrical portion or a tapered portion.

17 . The nozzle of claim 16 , wherein the first seal is in the form of an O-ring.

18 . The nozzle of claim 16 , wherein the second seal is in the form of an O-ring.
