A liquid blow molding method molds a bottomed tubular-shaped preform into a liquid-containing container in which a content liquid is held. The liquid blow molding method includes: a filling step of filling a first liquid in a first pressurizing source and filling a second liquid in a second pressurizing source; and a molding step of liquid blow molding the preform by simultaneously supplying, to the preform, the first liquid pressurized to a predetermined pressure by the first pressurizing source and the second liquid pressurized to a predetermined pressure by the second pressurizing source by simultaneously operating the first pressurizing source and the second pressurizing source.

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 blow molding device includes a cylindrical nozzle having, at a lower end thereof, a seal surface that, when the nozzle is inserted into a mouth part, abuts on a step surface provided at an inner circumferential surface of a preform in an axial direction to seal a gap between the nozzle and the inner circumferential surface of the preform. The preform has, at the inner circumferential surface thereof, the step surface to be abutted on by the seal surface of the nozzle in the axial direction. The step surface is tapered to be higher on a radial inner side than on a radial outer side.

Disclosed are preforms which incorporate improvements in the region of the neck and upper segment of the body to allow the production of lightweight containers, such as bottles suitable for containing water or other beverages. In accordance with certain embodiments, the improvements include a thinner neck finish area than conventional bottles, where the thinner area is extended into the upper segment of the body portion below the support ring. Reducing the thickness in these areas of the bottle allows for less resin to be used in forming the preform and bottle.

This reshaping device is arranged downstream of the heating device in the transport direction of the plastic preforms, and the reshaping device has a movable support, on which a plurality of reshaping stations are arranged for reshaping the plastic preforms into the plastic containers. The device also comprises a transport device, for transporting the heated plastic preforms individually from the heating device to the reshaping device, and a decorating device.

A method of manufacturing a liquid container, in which, a nozzle unit includes a blow nozzle having a supply port and a spare supply tube having, at a lower end thereof, a spare supply port. The method includes: an air exhausting step of exhausting the air in the preform to the outside by supplying a liquid into the preform from the spare supply port located at a bottom portion of the preform; a liquid blow molding step of molding the preform into a liquid container by supplying a pressurized liquid from the supply port into the preform; and a headspace forming step of forming a headspace by exhausting the liquid from the inside of the liquid container.

The invention relates to a method and to a device for producing containers (11) filled with a liquid filling material (21, 21.1) from preforms (2) made of a thermoplastic material, wherein the preform (2) is thermally conditioned before its transformation, and subsequently, during a forming and filling phase, in a mold (37) of a forming and filling station (10), it is transformed into the container (11) by means of the filling material (21, 21.1) as pressure medium, wherein the filling material (21, 21.1) is introduced from a forming and filling head (28) into the preform, wherein the forming and filling head (28) is moved from a rest position, which enables a supplying and insertion of a preform into the mold (37) of the forming and filling station (10), into a sealing position with respect the preform (2), wherein, during the transformation into the container (11), the preform (2) is preferably guided at least temporarily by a stretching rod (17) and stretched in axial direction, wherein, after the completion of the forming and filling phase, the container (11) is closed with a closure cap (15) before the container (11) is removed from the forming and filling station (10), wherein the closure cap (15) is supplied from a cap supplying device (50) into the area of the forming and filling station (10), and characterized in that, after the completion of the forming and filling phase, the forming and filling head (28) is moved from the sealing position into a position spaced apart from the container (11), then the closure cap (15) is supplied into the area between container (11) and forming and filling head (28), and then the closure cap (15) is pressed by the forming and filling head (28) in a longitudinal direction (32) of the container onto the container (11).
