    • Inner surface strain of a container is reduced by suppressing a temperature drop of blow air, and heat resistance of the container is increased by enhancing the degree of crystallization. A blow air supply unit for a blow molding machine for molding a hollow bottle container 1 by supplying heated blow air into a preform includes: a high-pressure air source 11 for generating high-pressure blow air; a high-pressure gate valve 12 for opening/closing a blow air channel on the downstream of the high-pressure air source 11; a heat exchanger 13 for heating the blow air on the downstream of the high-pressure gate valve 12; a throttle valve 14 for throttling the flow rate of blow air on the downstream side of the heat exchanger 13; and a switchover valve 15 for switching the blow air on the downstream of the throttle valve 14.
    • 通过抑制吹入空气的温度降低容器的内表面应变,通过提高结晶度来提高容器的耐热性。 用于通过向预成型体中供应加热的吹风而成型中空瓶容器1的吹塑机的吹气供应单元包括:用于产生高压吹风的高压空气源11; 用于打开/关闭在高压空气源11的下游的吹气通道的高压闸阀12; 用于加热高压闸阀12下游的吹气的热交换器13; 节流阀14,用于节流热交换器13下游侧的吹风流量; 以及用于切换节流阀14的下游侧的吹出空气的切换阀15。
