PROBLEM TO BE SOLVED: To reduce costs by blowing air rich in ozone through an air bore provided in an axial core of a driving pin when a container is blow molded by a hollow molding machine, and by sterilizing the container interior simultaneously with the container molding. SOLUTION: A resin melted and plasticized by an extruder head 2 is extruded in an extrusion station 1 to form a parison 3, and two-divided molds 4a, 4b are closed to sandwich the parison 3. After cutting by a cutter 5, a mold clamping device 6 moves toward a driving station 8 by slanting a sliding axis 7. An upwardly and downwardly movable driving pin 9 is disposed in a driving station 8, an air rich in ozone if blown from an ozone-rich air generator 11 through an air bore provided in the axial core, and the parison 3 is expanded along a cavity 4c of the two divided molds 4a, 4b, thereby sterilizing the interior while molding a container 10. After the blow-molded container is cooled and solidified, the driving pin 9 rises. |
