Abstract: 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.

Abstract: 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 pressure source (120, 20) includes an inlet (146, 150, 46, 50) and a piston-like device (140, 40).

Abstract: A method of forming a container (1) and a container (1) formed thereby. A preform (2), having a generally cylindrical body (60, 8) extending between a closed end (12) and an open mouth, is placed within a mold (20, 22) having surfaces corresponding in shape to the desired container (1). An incompressible medium, which is the end product that remains in the molded container (1), is injected under pressure into the preform (2). Under the influence of the incompressible medium, the preform (2) is expanded into contact with the surfaces defining the cavity, simultaneously forming and filling the container (1). During expanding of the preform (2), portions of the plastic material are forced into a series of recesses (72) defined in the cavity surface (82, 85). With the incompressible medium contained therein, the container (1) is removed from the mold (20, 22) and including a series of raised dots corresponding to the series of recesses (72) defined in the cavity surface (82, 85).

Abstract: A method of forming a container from a plastic preform while using a liquid as a blow medium. During the method, liquid is withdrawn from the container to reduce pressure within the container prior to disengaging of the injection head from the container. In one aspect the method involves the opening of a recirculation valve to reduce the pressure. The opening of the recirculation valve allowing air dispersed within the liquid to rise to the top of the container before disengaging of a forming head from the container. As a result, splashing and spillage of liquid from the neck of the container is eliminated when the forming head disengages from the container.
