ABSTRACT:
A method and an apparatus for manufacturing a tin-like container comprising a sleeve formed body or jacket (1) and at least one end closure (2, 3), in which the jacket (1) and the end closure or the end closures (2, 3) at the interior side of the container has a layer (5) of a constant heat weldable, high frequence weldable or ultrasonic weldable material, and in which the container is closed under sealed condition in that the end closure (2, 3) is formed with an edge flange extending all around the end closure and is introduced in the jacket (1) and is welded thereto. The introduction of the end closure (2, 3) in the jacket (1) is made by means of a press piston (14) having a press cone (15) which is formed with an expandable means (15d; 29). In the non-expandive condition the expandable means (15d; 29) is located inside of the cone surface, and it is adapted to become expanded before or at the same time as being welded to the innersurface of the container, whereby a resilient additional pressure line is obtained round the entire weld surface and along at least some part of the height of the weld surface.
