    • PROBLEM TO BE SOLVED: To provide a manufacturing process of a resin container which can effectively avoid the deformation of the mouth of a preform to become the opening end of the preform, to which blowing air is supplied, due to the heat, the pressure, etc. of the blowing air, when manufacturing the resin container of a predetermined container shape by blow molding the preform by supplying the blowing air to the preform formed in a cylindrical shape with a bottom, and to provide a blow molding machine. SOLUTION: The blowing air supply port 15 of a blow molding nozzle 1 is communicated with the mouth 21 of the preform 2 in an airtight manner. The blowing air is supplied into the preform 2, and the cooling medium is supplied to the outer circumference surface side of the mouth 21 of the preform 2. COPYRIGHT: (C)2009,JPO&INPIT
    • 要解决的问题:提供一种树脂容器的制造方法,其可以有效地避免预成型件的口部变形,从而成为由于热量而被供给吹送空气的预成型件的开口端, 吹送空气的压力等,当通过向形成为具有底部的圆筒形状的预成型体供给吹送空气来吹塑成型预制件来制造预定容器形状的树脂容器时,提供吹塑机。 解决方案:吹塑喷嘴1的送风口15以气密的方式与预型件2的口21连通。 吹送空气被供给到预成型体2中,冷却介质供给到预成型体2的口部21的外周面侧。(C)2009,JPO&INPIT
