造。[Scope of Claim for Utility Model Registration] A pair of split molds each having an open-type mold cavity half face with a parison inlet half face opening to the outside at the upper end of the mold cavity half face and a parison outlet face opening opening to the outside at the lower end of the mold cavity half face. In this case, the part near the half surface of the parison inlet port has an opening area necessary to utilize sufficient suction to feed the parison into the mold cavity as a whole, and has a small diameter to the extent that it does not allow the parison to bulge outside. A split mold ventilation structure used for suction-type parison supply, with numerous small suction ventilation holes penetrating from the inside of the mold cavity to the outside.
