Abstract

PURPOSE:To provide a vessel of high mechanical strength, etc. when biaxial- stretch-blow-forming the vessel by stretching while keeping the temperature of a blowing die within a specific range and then filling completely a liquid of a specific temperature into the blow-formed vessel. CONSTITUTION:When forming a biaxial-stretch-blown vessel of a thermoplastic polyester such as polyethylene terephtalate, a parison with a bottom heated by keeping the temperature of a blowing die within a temperature range which satisfies an equation I(Tg is the glass transistion temperature of the thermoplastic polyester; MT is the temperature of the blowing die) is stretched in the axial direction, and at the same time, pressurized gas is blown into the parison to stretch it laterally. Next, after filling a liquid of a temperature which satisfies an equation II (LT is the temperature of the liquid) into the formed blow vessel completely, the blow vessel is taken out, obtaining a vessel of high thermal contraction resistibility, etc.
