ABSTRACT:
A process for forming a collapsable tube having a flexible inner tube and a resilient outer tube. A shoulder member is formed having connecting surfaces. A flexible inner tube is joined to the shoulder member at a connecting surface. An outer tube encompassing the inner tube is joined to the shoulder member at a separate connecting surface so that the outer tube overlaps the joint between the inner tube and shoulder member. To resist permeation, the inner tube is formed by lap welding a laminated sheet of different natured materials and depositing a molten material along an edge of the sheet to seal it.
