ABSTRACT:
An apparatus for blow molding bottles having a hole formed in a molded interior recess is provided. The apparatus includes a mold having a neck forming cavity having an end flange surface. A recess forming rod is slideable within a hole in the end flange surface from an initial position wherein a face of the rod is withdrawn into the hole in the mold to an extended position wherein the face of the rod protrudes into the neck forming cavity so as to create the molded interior recess. A punch is slideable within a hole in the rod from an initial position wherein a face of the punch is withdrawn into the hole in the mold to an extended position wherein the face of the punch protrudes beyond the face of the rod into the neck forming cavity so as to create the hole in the interior recess.
