  • Publication number: 20240083093
    Abstract: 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.

  • Patent number: 11833729
    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).

  • Patent number: 11833728
    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.

  • Publication number: 20230219278
    Abstract: Ways to produce a plurality of preform (5) temperature profiles are provided that employ systems having a first heating means, a second heating means, and a first transfer means. The a first heating means has a first preform (5) path, imparts a first temperature profile to a preform (5) passing through the first preform (5) path, and has a first dispensing means configured to selectively dispense the preform (5) passing through at least a portion of the first preform (5) path. The second heating means has a second preform (5) path, imparts a second temperature profile to a preform (5) passing through the second preform (5) path, and has a second dispensing means configured to selectively dispense the preform (5) passing through at least a portion of the second preform (5) path. The first transfer means selectively transfers a preform (5) between the first preform (5) path and the second preform (5) path.

  • Publication number: 20230219277
    Abstract: Ways for controlling a level of a product in a container are provided that include engaging an exterior surface of the container containing the product at a first product level. A force is applied to the exterior surface of the container to cause the container to change from a first volume to a second volume. Cessation of the force results in the container containing the product at a second product level. The second product level can provide an accurate and reproducible final product level in the container.

  • Publication number: 20230191685
    Abstract: Ways for simultaneously forming and filling a container with a product are provided that include a mold cavity, a two-stage injection unit, and a blow nozzle. The mold cavity defines an internal surface and is configured to accept a preform. The two-stage injection unit receives and dispenses the product where a first stage includes an extruder and a second stage includes an accumulator. The extruder imparts mechanical energy to the product to reduce a viscosity of the product and transfers the reduced-viscosity product to the accumulator. The accumulator receives the reduced-viscosity product from the extruder and dispenses a charge of the reduced-viscosity product. The blow nozzle transfers the charge of the reduced-viscosity product dispensed from the accumulator into the preform to urge the preform to expand toward the internal surface of the mold cavity and form a resultant container.

  • Publication number: 20230191682
    Abstract: 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.

  • Patent number: 11639020
    Abstract: An apparatus and method for simultaneously forming and filling a plastic container without the use of a mold forming a mold cavity (116, 16) is provided. A pressure source (120, 20) includes an inlet (146, 150, 46, 50) and a piston-like device (140, 40). The piston-like device (140, 40) is moveable in a first direction wherein liquid is drawn into the pressure source (120, 20) through the inlet (146, 150, 46, 50) and in a second direction wherein the liquid is urged toward the preform (112, 12). A blow nozzle (122, 22) may be adapted to receive the liquid from the pressure source (120, 20) and transfer the liquid at high pressure (P2) into the preform (112, 12) thereby urging the preform (112, 12) to freely expand until an unopened end thereof contacts a platen (118). The platen (118) forms a bottom in a resultant container. The liquid remains within the container as an end product.

  • Patent number: 11541590
    Abstract: A method of making a container via a simultaneous filling and forming of the container with a liquid product is disclosed. The method comprises the steps of extruding a parison (12, 2), capturing a portion of the parison (12, 2) within a mold (15), and inflating the captured portion of the parison (12, 2) against the mold (15). The captured portion of the parison (12, 2) is inflated against the mold (15) by introducing the liquid product into an interior of the captured portion of the parison (12, 2), wherein the liquid product forms an end product to be sealed within the resultant container.
