1. A device for producing and filling containers, the device comprising:
a plasticized plastic material extruder with an annular extrusion nozzle extruding a hose from the annular extrusion nozzle in 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 conveying a process gas into an interior of the hose and having a first guide duct extending inside the extrusion head and outside of the filling mandrel; and
a first exhaust gas duct extending in the extrusion head, being spaced from the first guide duct, and discharging the process gas from the 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.
