Abstract

PURPOSE:To improve a size stability and a mechanical strength when heating is effected, by a method wherein temperature of a blow mold is held at a given temperature, and a pressurized air is passed through under a given pressure temperature condition after a heated parison with a bottom is stretched vertically and horizontally. CONSTITUTION:Temperature of a blow mold 8 is held by an inequality I (where Tg is a glass transition temperature deg.C of thermoplastic polyester, and MT is a blow mold temperature deg.C). A parison 12 with a bottom is stretched in the axial direction and is also stretched transversely by blowing a pressurized gas through an air passage 5 into the parison 12. A low-temperature pressurized gas, which satisfies an inequality II (where AT is a low-temperature pressurized gas temperature deg.C) and is equal to or lower than that of the aforesaid pressurized gas, is passed through the air passage 5 into a molded blow container 12', and the cooled blow container 12' is then unloaded. A suitable temperature of the blow mold is at least 10 deg.C higher than the glass transition temperature, and a preferable heat-curing time is 5-15sec. A suitable temperature of the pressurized gas is about the normal temperature.
