Method for producing a liner of a container

1. A method for manufacturing a liner of a container including at least one container penetration element, the method comprising the steps of:

providing a positioning apparatus including an elongate shaft having a first end and a second end;

providing a first container penetration element;

providing a second container penetration element;

providing a parison;

releasably coupling the first container penetration element onto the first end of the positioning apparatus to form a substantially fluid-tight connection;

releasably coupling the second container penetration element onto the second end of the positioning apparatus to form a substantially fluid tight connection;

guiding the parison around the positioning apparatus having the first container penetration element and the second penetration element releasably coupled thereto; and

forming the parison into a hollow liner using a fluid flowing through the positioning apparatus, wherein the first container penetration element and the second container penetration element each span an exterior of the hollow liner to an interior of the hollow liner.

2. The method according to claim 1 , wherein the substantially fluid-tight connection between the first container penetration element and the first end of the positioning apparatus is one of a threaded connection, a dovetail interlock connection, a ball and detent connection, and a lock bar connection.

3. The method according to claim 1 , further comprising the step of: providing a fluid source in fluid communication with the positioning apparatus, wherein the fluid source provides the fluid to expand the parison and form the hollow liner.

4. The method according to claim 1 , further comprising the step of: removing the positioning apparatus from the hollow liner by an axial movement of the positioning apparatus through a passageway formed in at least one of the first container penetration element and the second container penetration element.

5. The method according to claim 1 , wherein the substantially fluid-tight connection between the second container penetration element and the second end of the positioning apparatus is one of a threaded connection, a dovetail interlock connection, a ball and detent connection, and a lock bar connection.

6. The method according to claim 1 , wherein the positioning apparatus includes a passageway and a plurality of apertures formed therein, the passageway and the plurality of apertures providing fluid communication between the fluid source and an environment surrounding the positioning apparatus.

7. The method according to claim 1 , wherein the positioning apparatus is a telescoping apparatus.

8. The method according to claim 1 , wherein the first container penetration element and the second container penetration element are disposed in opposing axial ends of the liner.

9. The method according to claim 1 , further comprising the step of aligning at least one of the first penetration element and the second penetration element in the parison using the positioning apparatus.

10. A method for manufacturing a liner of a container including at least one container penetration element, the method comprising the steps of:

providing a parison;

guiding the parison around a positioning apparatus having a first container penetration element and a second penetration element releasably coupled thereto, the first container penetration element and the second container penetration element each forming a substantially fluid-tight connection with the positioning apparatus;

aligning the first penetration element and the second penetration element in the parison using the positioning apparatus; and

forming the parison into a hollow liner using a fluid flowing through the positioning apparatus, wherein the first container penetration element and the second container penetration element each span an exterior of the hollow liner to an interior of the hollow liner.

11. The method according to claim 10 , further comprising the step of: providing a fluid source in fluid communication with the positioning apparatus, wherein the fluid source provides the fluid to expand the parison and form the hollow liner.

12. The method according to claim 10 , further comprising the step of: removing the positioning apparatus from the hollow liner by an axial movement of the positioning apparatus through a passageway formed in at least one of the first container penetration element and the second container penetration element.

13. A method for manufacturing a liner of a container including at least one container penetration element, the method comprising the steps of:

providing a parison;

providing a positioning apparatus having a first end and a second end;

releasably coupling a first container penetration element onto the first end of the positioning apparatus to form a substantially fluid-tight connection;

releasably coupling a second container penetration element onto the second end of the positioning apparatus to form a substantially fluid-tight connection;

guiding the parison around the positioning apparatus having the first container penetration element and the second penetration element releasably coupled thereto;

aligning the first penetration element and the second penetration element in the parison using the positioning apparatus; and

blow molding the parison into a hollow liner using a fluid flowing through the positioning apparatus, wherein the first container penetration element and the second container penetration element each span an exterior of the hollow liner to an interior of the hollow liner.

14. The method according to claim 13 , further comprising the step of: providing a fluid source in fluid communication with the positioning apparatus, wherein the fluid source provides the fluid to expand the parison and form the hollow liner.

15. The method according to claim 13 , further comprising the step of: removing the positioning apparatus from the hollow liner by an axial movement of the positioning apparatus through a passageway formed in the first container penetration element and a passageway formed the second container penetration element.
