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. | |
