Claim Text:
1. A method of producing and filling containers made of thermoplastic material, comprising the steps of: inserting an extruded plastic tube into an open mold having movable mold parts, closing the mold parts with the plastic tube therein, expanding the plastic tube by a pressure gradient acting on the plastic tube to form a container, filling the container with filling material to a level in the container, raising the level of the filling material in the container by displacing a container volume by moving a displacer a first time to a first position, forming a container closure from the plastic tube by closing main head jaws of the mold, with recesses in the main head jaws remaining open and forming at least one open venting cannula from a part of the plastic tube located in the recesses while the displacer is in the first position, raising the level of the filling material in the container by displacing the container volume by moving the displacer a second time to a second position spaced from the first position, with air being displaced from the container through the open venting cannula, and closing the venting cannula by closing auxiliary head jaws of the mold.
