The present invention provides a bottomed cylindrical container, comprising a body wall, a bottom wall, and a ring-shaped foot downwardly extending from the bottom wall, said container being produced by thermo-molding a resin sheet, characterized in that said foot is formed by folding an inner wall by compressed fluid to be fusion-bonded with an outer wall, so as to form the foot comprising the inner wall and the outer wall. The present invention also provides a bottomed cylindrical container, comprising a body wall having a grounding edge at a lower end thereof, and a bottom wall, said container being produced by thermo-molding a resin sheet, characterized in that said bottom wall connects with an upper edge of an inner wall produced by folding back the body wall along the grounding edge and by fusion-bonding it to an inner periphery of the body wall. In addition, the present invention provides the methods for thermo-molding these containers and their apparatuses.

Refilling container having flexible shoulder portion movable between

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.
