利用液体吹塑成形的容器制造方法
摘要：
本发明的利用液体吹塑成形的容器制造方法具备顶部空间形成工序，所述顶部空间形成工序是在将容器(C)配置在型腔(12)内的状态下，利用按压杆(20)按压在容器(C)的底部(Cb1)成形为向上凸状的底面面板部(Cb11)而使其翻转，塑性变形为呈向下凸状的形状，由此在容器(C)的上部形成顶部空间(HS)。
摘要（英）：

The method for producing a container by liquid blow molding has a head space formation step for using a push-down rod (20) to push down on a bottom panel part (Cb11) formed in an upward convex shape in the bottom part (Cb1) of a container (C) in a state in which the container (C) is disposed in a cavity (12), and inverting and plastically deforming the bottom panel part (Cb11) into a shape havinga downward convex shape, thereby forming a head space (HS) in the upper part of the container (C).
