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.

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).

An apparatus for forming plastic preforms into plastic containers, includes at least one forming station which forms the plastic preforms into the plastic containers by applying a flowable medium to the plastic preforms, wherein the forming station includes a blow mold, and a rod-like body which is insertable into the plastic preforms via a mouth of the plastic preforms, and a moving device which is configured for moving the rod-like body in the longitudinal direction of the plastic performs. The rod-like body has a channel for guiding the flowable medium, and the forming station has a valve device controlling the supply of the flowable medium into the channel. The valve device is arranged on the moving device and/or a ratio between an inner diameter of the rod-like body and an outer diameter of said rod-like body is, at least in sections, smaller than or equal to 0.5.

A soft-melted parison is disposed in molds forming a shape of a measurement pipeline portion 10, the parison is expanded by means of gas inflow, and blow molding is performed. The shapes of a pipe body 11, a fluid inlet portion 12, and a fluid outlet portion 13 are formed by an inner mold of the molds. Ultrasonic wave input-output portions 14a and 14b bulging outwards in a sealed manner are formed on both sides positioned in the oblique direction of the pipe body 11 with respect to a center line of the pipe body 11. Parts of the ultrasonic wave input-output portions 14a and 14b are wall surfaces 15a and 15b for attaching ultrasonic wave transmission-reception units. The measurement pipeline portion 10 is obtained by cutting end portions of the fluid inlet portion 12 and the fluid outlet portion 13 after the parison is solidified.
