Abstract
A process for producing thermoplastic containers () extrudes a plastic tube into opened movable mold parts (). The main mold parts () form the container main part (). The bottom parts are closed to close and weld the tube bottom end. The tube () is widened by a pressure gradient acting on it, forcing the tube against the wall of the mold parts () to form the container. The mold parts are then moved into the position to open the mold for removal of the formed container (). The container bottom is made in the form of a cup-like bottom part () axially extending into the container main part () by the bottom part being everted into the interior of the container () to form a bottom elevation ().
