Abstract: A liquid container manufacturing method includes: a liquid blow molding step of molding a preform into a liquid container; and a headspace formation step of forming a headspace, by discharging, in a state in which a liquid supply path is closed, a liquid out of the liquid container through a discharge port, the discharge accomplished by drawing-in by a liquid drawing source. In the headspace formation step, a pressurized gas is supplied from a pressurized gas supply source into the liquid container through a gas supply port to thereby assist the discharge, by the drawing-in, of the liquid out of the liquid container through the discharge port, and, when a pressure in a discharge path has increased to a set value, the supply of the pressurized gas by the pressurized gas supply source is stopped.

Abstract: A blow molding apparatus is configured to blow mold a preform into a container by supplying a pressurized incompressible fluid into the preform from a pressurized fluid supply unit. The blow molding apparatus includes: a drawing and discharging flow path connected to a drawing orifice; a fluid drawing source to apply drawing force to the drawing and discharging flow path, after blow molding is completed and after and/or while the blow nozzle is moved to a standby position, to draw the incompressible fluid adhering to the blow nozzle; and a pressurized gas supply source to supply a pressurized gas to the drawing and discharging flow path, after blow molding is completed and after a next preform is placed into the mold, to cause the incompressible fluid inside the drawing and discharging flow path to flow out toward the inside of the preform or toward the inside of a container.

Abstract: A blow molding device includes a nozzle, a pressurized fluid supply source, a seal body, and a rod. The seal body includes a tubular wall. A communication depression extending from a lower end of the tubular wall to a communication port open on an outer circumferential surface of the tubular wall is provided in an inner circumferential surface of the seal body. A communication path is provided in the nozzle. The blow molding device further includes a fluid suction source configured to suck an incompressible fluid from the communication depression through the communication path and the communication port, and/or a pressurized gas supply source configured to supply a pressurized gas that blows off the incompressible fluid from the communication depression through the communication path and the communication port.
