there is disclosed a method and apparatus for blow molding a thermoplastic container . the blow molded container is fabricated conventionally from a downwardly descending thermoplastic extruded parison tubing which passes between sets of separated mold halves . one of the sets of mold halves is adapted to accommodate an insert positioned on a retaining wand . when the molds close and the parison is conventionally blow molded the wand continues to support the insert while at the same time extends beyond the container so blow molded . the insert may be , for instance , a nozzle for a thermoplastic bottle having a cap molded thereabout having break away features whereby the cap may be removed . in another embodiment the wand is supported by a block located externally of the mold halves and in some cases axially with respect to the molds .
