摘要： Systems and methods for making a reduced material container are provided that hold a preform adjacent to an open end of the preform, stretch the preform, close a mold about the stretched preform to form a truncated preform, and introduce a pressurized fluid into the truncated preform to expand the truncated preform and form the reduced material container. A stretch rod can be inserted into the preform to mechanically stretching the preform. The mold accepts the preform at a first end thereof, has an open state and a closed state, and the closed state forms a cavity defining an internal surface having a second end located remotely from the first end. A first length is defined by a distance between the first end and the second end, the stretch rod mechanically stretching the preform to a second length, the second length being greater than the first length.

摘要： Provided is a stretching rod for a molding unit for manufacturing a container from a preform and a method for manufacturing a container by stretch blow-molding. The stretching rod extends longitudinally, parallel to a main axis Y, and comprises a body of cylindrical or tubular form, a distal end in the extension of said body, at least one internal channel to allow the circulation of a cooling gas to said distal end, a flat situated at the distal end of the stretching rod, an end-fitting protruding from said flat and a plurality of orifices, said orifices being fluidically connected with said internal channel and being distributed around said end-fitting on said flat. The rod can include an annular skirt in the extension of said body, at said distal end, said skirt having a height less than the height of said end-fitting.

摘要： Disclosed is a method for cooling heated molds from a machine for molding containers from thermoplastic material by stretch-blow molding hot preforms using at least one pressurized fluid. The cooling method includes, in order to cool the molds, at least one cooling step that involves selectively feeding at least one cooling fluid into the molding cavity of at least some of the molding units that, after the carousel has been stopped in order to immobilize the molding units at least during the cooling step, are located in a predetermined cooling region in which the molding units are in a closed position.

摘要： 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).

摘要： 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.

摘要： Ways for simultaneously forming and filling a container with a liquid product are provided that include a mold cavity, a dispensing means, a blow nozzle, a conduit, and a hydrophobic surface. The mold cavity defines an internal surface and accepts a preform. The dispensing means receives the liquid product and dispenses a charge of the liquid product. The blow nozzle transfers the charge of the liquid product dispensed from the dispensing means into the preform to urge the preform to expand toward the internal surface of the mold cavity and form a resultant container. The liquid product remains within the container as an end product. The conduit fluidly couples the dispensing means to the blow nozzle. The hydrophobic surface contacts the liquid product when the system simultaneously forms and fills the container, where the hydrophobic surface forms part of the dispensing means, the blow nozzle, and/or the conduit.
