Claim:
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.
