An apparatus for manufacturing a liquid container, in which a nozzle unit has a seal body disposed in a supply path, the seal body has an annular first seal portion, an annular second seal portion and a spare supply path extending from a flow inlet located between the first seal portion and the second seal portion to a flow outlet located closer to a tip side of the seal body than the second seal portion, and the seal body can move between a blocked position where the first seal portion sits on the supply path, a spare supply position where the first seal portion separates from the supply path and the second seal portion sits on the supply path and an open position where the first seal portion separates from the supply path and the second seal portion separates from the supply path.

The method relates to a method for filling a container (13, 32) with carbonized liquid filling material and for closing the filled container, in which the filling material is introduced in a filling station (10, 30) by a filling head (11, 33) at defined filling pressure into the container (13, 32), wherein the filling head (11, 33) is firstly moved from an idle position, which permits supplying and inserting a container (13, 32) into the filling station (10, 30), into a working position toward the inserted container, in which an end region (16) of the filling head seals off the opening (14) of the container, the container (13, 32) is then filled, the filling head (11, 33) is moved after completion of the filling phase back out of the working position into an idle position spaced apart from the container (13, 32) and the container (13, 32) is then closed in the filling station (10, 30) using a cap (20) at least enough that filling material can no longer escape, and the container (13, 32) is then removed from the filling station (11, 33), characterized in that before the movement of the filling head (11, 33) from the working position into the idle position spaced apart from the container (13), an overpressure lying between the ambient pressure and the filling pressure is set in a pressure chamber (15) of the filling station (10, 30) surrounding the opening (14) of the inserted container (13, 32), which overpressure is selected in such a way that possible foaming up of the filling material located in the container (13, 32) is minimized enough that filling material does not escape from the container (13, 32) when the filling head (11, 33) is raised out of the working position after the filling procedure.

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.

A liquid container manufacturing method includes: a nozzle fitting step of fitting a blow nozzle to a mouth of a preform; a liquid blow molding step of liquid blow molding the preform into a halfway shape by supplying a predetermined volume of liquid that is less than a full capacity of a liquid container from a liquid supply port of the blow nozzle to the preform; and an air blow molding step of molding the preform into a shape conforming to an inner surface of a mold for blow molding by supplying pressurized air from a gas supply port to the preform after the liquid supply port is closed, in which a headspace is generated in the liquid container, having a volume corresponding to a difference between a volume of the liquid supplied to the preform in the liquid blow molding step and a full capacity of the liquid container.

There is provided a system, a method and preform suitable for executing liquid forming of the preform into a final-shaped container. The present technology includes various improvements to methods, apparatuses, and systems for forming final-shaped containers from preforms using a liquid destined to be contained in the final-shaped container.

A system for simultaneously forming a container and filling the container with a product. The system includes a thermoplastic preform and a nozzle. The preform is configured to be molded into the container. The nozzle is for a forming/filling head configured to inject the product into the preform sealed to the nozzle for simultaneousl y forming the container from the preform and filling the container with the product. Upon insertion of a finish of the preform between an outer flange and an inner flange of the nozzle, the finish seals to the nozzle through cooperation between: a brim of the preform and an upper sealing surface of the nozzle between the outer flange and the inner flange; a sealing ledge of the finish and a lower sealing surface of the inner flange; and an inner sealing sidewall of the finish and an outer sealing surface of the inner flange.

A method for producing containers filled with liquid content from preforms made of thermoplastic material. The liquid content is fed as a pressure medium into thermally conditioned preforms during a forming and filling phase in a mold of one of a plurality of forming stations arranged circumferentially spaced apart on a common, continuously rotationally driven working wheel. A compensating device compensates for thermal consequences of centrifugal force acting on the liquid content fed into the preform during the forming and filling phase. The compensating device imparts a temperature profile to the preform in a circumferential direction, which is not point-symmetrical in relation to a longitudinal axis of the preform to produce a thermally differentiated partial circumferential region. The preform is inserted into the mold such that the thermally differentiated partial circumferential region faces in a radial direction of the working wheel.

Ways for simultaneously forming and filling a container are provided. A hydraulic intensifier (60) receives a first liquid (18) and dispenses the first liquid (18) at a first pressure, where a moveable member (62) having a first surface (64) contacts the first liquid (18) and a second surface (66) contacts a second liquid (68). The second liquid (68) provides a second pressure on the second surface (66) so that the first pressure is applied to the first liquid (18) by the first surface (64). The first surface (64) has a smaller area than the second surface (66) and the first pressure is greater than the second pressure. A blow nozzle (22) transfers the first liquid (18) at the first pressure into a preform (12) within a mold cavity (16) to urge the preform (12) to expand toward an internal surface (34) of the mold cavity (16) and form a resultant container. The first liquid (18) remains within the container as an end product.

Ways of simultaneously forming and filling a container include and/or use a mold (14), a pressure source (20), a blow nozzle (22), and one or more dampening means. The mold (14) has a cavity defining an internal surface and is configured to accept a preform (12). The pressure source (20) is configured to provide a pressurized liquid (18). The blow nozzle (22) is configured to receive the pressurized liquid (18) from the pressure source (20) and transfer the pressurized liquid (18) into the preform (12) to urge the preform (12) to expand toward the internal surface of the mold cavity (16) and form a resultant container, where the liquid (86, 96) remains within the container as an end product. The one or more dampening means is/are configured to reduce water hammer, for example, by coupling such dampening means to one of the blow nozzle (22) and the mold (14).

Systems and methods for making a reduced material container (105) are provided that hold a preform (130) adjacent to an open end (165) of the preform (130), stretch the preform (130), close a mold (110, 120) about the stretched preform (175) to form a truncated preform (185), and introduce a pressurized fluid (160) into the truncated preform (185) to expand the truncated preform (185) and form the reduced material container (105). A stretch rod (125) can be inserted into the preform (130) to mechanically stretching the preform (130). The mold (110, 120) accepts the preform (130) at a first end (135) thereof, has an open state and a closed state, and the closed state forms a cavity (140) defining an internal surface (145) having a second end (150) located remotely from the first end (135). A first length (155) is defined by a distance between the first end (135) and the second end (150), the stretch rod (125) mechanically stretching the preform (130) to a second length (170), the second length (170) being greater than the first length (155).
