Device for producing and filling container products

A device for producing and filling containers, the device comprising:

• a plasticized plastic material extruder extruding a hose from an extrusion head of the extruder;
• a mold movable between an open position receiving the hose, a molding position forming an open container and a closed position sealing the container closed;
• a hose guide guiding the hose between the extrusion head and the mold;
• a filling mandrel longitudinally movable in the extrusion head to a functional position inside the open container to introduce filling material into the open container;
• a first process gas feeder duct in the extrusion head adjacent to an interior surface of the hose and adjacent to at least one exit point of the hose from the extrusion head, the first process gas feeder duct conveying a process gas into the hose along the interior surface of the hose;
• and
• a first exhaust gas duct extending in the extrusion head, being spaced from the first process gas feeder duct, and discharging the process gas from an interior of the hose,
• wherein the first exhaust gas duct opens into the interior of the hose and extends through the extrusion head parallel to the filling mandrel.
