ABSTRACT:
A blowhead assembly for receipt over a parison finish to blow the parison within a blow mold and simultaneously cool the parison finish includes a blowhead body having a first chamber at one end for receipt over the finish of a parison in a blow mold, and at least one passage in the blowhead extending to the chamber from a first inlet for directing cooling air onto the external surface of a parison finish in the chamber. A second chamber in the blowhead body is spaced from the first chamber, and at least one second passage in the blowhead body extends to the second chamber from a second inlet for directing blow air into the second chamber. A first tube extends from the second chamber through the first chamber for receipt within a parison finish in the first chamber to feed blow air from the second chamber into the parison. A second tube extends from an exhaust passage in the blowhead body through the second chamber and through the first tube for receiving exhaust air from the parison. The second tube is coaxial with the first tube and extends beyond the free end of the first tube. The second tube has at least a free end that flares radially outwardly for deflecting blow air from the first tube radially outwardly within the parison.
