A method for producing at least one molded, filled and sealed container product (10) includes at least the method steps of: extruding a hose (32) by an extrusion device (12) using supporting gas in vertical extrusion direction in a preforming position; sealing the hose (32) at its lower end and cutting it at its upper open end; cutting the parison (22) to length; transporting the cut parison by a gripper device (20) in linear transport direction transverse to the extrusion direction from the preforming position into an opened molding tool (18); transferring the parison (22) into the opened molding tool (18) by the gripper device (20) in a main forming position; sealing the molding tool (18) for further forming of the parison (22) by a pressure gradient; filling and sealing the parison (22); and returning the gripper device (20) to the preforming position for a repeated sequence of the above method steps.
