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.

A hydraulic blow molding apparatus having a container forming station with a forming head coupled to a source of liquid blow medium. The container forming station further includes a mold configured to receive a preform and has interior surfaces that define the container shape. The container forming station injects a liquid end product into the preform and expands the preform to simultaneously form and fill a container with the liquid end product. Prior to the container being removed from the container forming station and while it is still full of the liquid end product, a seal is engaged with the container.

A method for producing containers, filled with liquid filling material, from thermally conditioned preforms, in which method the filling material is introduced under pressure through a filling valve into the preform at a forming and filling station, wherein the filling material is provided by a filling material source and is pumped into the preform by means of a displacement pump, which is provided between the filling material source and the forming and filling stations, when the filling valve is open, wherein at least two forming and filling stations (12, 14, 11, 13, 32, 33) are associated with each displacement pump (23, 24, 36), which forming and filling stations are supplied, in particular successively, with filling material by the displacement pump (23, 24, 36).

A liquid blow molding method of molding a synthetic resin preform having a mouth portion into a liquid container of a predetermined shape, including: an air-liquid replacement step of supplying a liquid into the preform from the mouth portion through a blow nozzle and discharging the air inside the preform to the outside; an air-liquid separation step of separating the air from the liquid inside the preform by vibrating the preform; and a blow molding step of molding the preform into a container of a predetermined shape by supplying a pressurized liquid into the preform from the mouth portion through the blow nozzle, after the air-liquid separation step.

A blow molding device includes: a tubular-shaped nozzle; a tubular-shaped sealing body configured to be displaced between closing and opening positions; and a stretching rod surrounded by the sealing body. The sealing body includes a tubular wall, which has a drawing-in hole extending from one end to another end, the one end being open at a lower end of the tubular wall, and the other end being open at an outer circumferential surface of the tubular wall. The nozzle has a drawing-in path configured to communicate with the other end of the drawing-in hole when the sealing body is in the closing position. The blow molding device further includes a fluid drawing-in source configured to draw in the incompressive fluid from the drawing-in path.

A liquid container manufacturing method includes: a liquid blow molding step of molding a preform into a liquid container having a shape conforming to an inner surface of a blow-molding mold, by supplying a pressurized liquid to an interior of the preform through a supply path in a state where a blow nozzle is engaged to a mouth of the preform; and a headspace forming step of forming a headspace in the liquid container, by discharging the liquid from an interior of the liquid container through a discharge port in a discharge rod extending to the interior of the liquid container through the blow nozzle, by introducing a pressurized gas to the interior of the liquid container through a gas inflow path in a state where the supply path is closed.

In a liquid container manufacturing method, a nozzle unit includes a flow path that is configured to be opened and closed by a valve embedded in a blow nozzle, and a seal pin arranged in a pin accommodating space included in the flow path has a protruding portion configured to enter a communication space in a closed state of the valve. The liquid container manufacturing method includes a liquid blow molding step of molding a preform into the liquid container, by supplying, to an interior of the preform, a pressurized liquid.

A liquid-blow molding apparatus including a blow-molding mold that houses a preform leaving a mouth that serves as an open end thereof; a blow nozzle that supplies a pressurized liquid into the preform; a partition-wall member that closely surrounds a periphery of an outer-wall surface of the mouth of the preform and defines a mouth-external pressurized space with the outer-wall surface; and pressurized liquid-supply means for supplying a pressurized liquid into the mouth-external pressurized space so that pressure in the mouth-external pressurized space is higher than pressure inside the preform during liquid blow-molding.

A method reduces the microbiological loading of container products made at least partially of at least one plastic material. As part of a first production process, a plastic granulate (29) is fed to an extruder device (19), which melts the granulate (29). As part of a subsequent production process, the melted granulate is forwarded onto a blow-molding, filling and sealing machine for obtaining the respective container product. At least in parts of the first production process, the plastic material undergoes at least one of the following treatment steps: high-energy radiation and/or plasma treatment and/or a gas having a sterilizing effect.

A method of manufacturing a content liquid containing bottle includes: a molding step of blow molding a preform into a bottle that includes a mouth portion, a shoulder portion expanding in a direction away from the mouth portion, a barrel portion, and a bottom portion; a cap attachment step of attaching a cap to the mouth portion of the bottle filled with a content liquid; and a label attachment step of placing a tubular shrink label over outside of the bottle, and thermally shrinking the shrink label to attach the shrink label to the bottle, wherein in the label attachment step, the shrink label is thermally shrunk in a state in which one end of the shrink label is located at a region of the shoulder portion in which an inner surface is in contact with the content liquid.
