Patent number: 11426922Abstract: Systems and methods for simultaneously forming and filling a container are provided where a pressure source is accelerated from an initial state to attain a predefined process speed while applying pressure to a volume of fluid. The volume of fluid is fluidly coupled to a preform upon attaining the predefined process speed, the pressure source directs at least a portion of the volume of fluid into the preform and stretching the preform to form the container, where the container includes at least the portion of the volume of fluid. The volume of fluid is fluidly decoupled from the container and the pressure source is then decelerated from the predefined process speed toward the initial state.Type: GrantFiled: June 29, 2018Date of Patent: August 30, 2022Assignee: DISCMA AGInventors: Richard Sieradzki, G. David Lisch, Jr., Gregory Carpenter

Patent number: 10682802Abstract: An injection nozzle for cooling and providing counter pressure to a neck of a preform during a forming of a container from the preform. The injection nozzle includes a manifold that defines a receiving space into which the neck of the preform is received. A cavity is also defined in a part by an inner wall and an outer wall of the manifold and a plurality of ports are provided through the inner wall to communicate the cavity with the receiving space. When a cooling medium is received into the cavity, the cooling medium is directed through at least some of the ports toward the neck of the preform located within the receiving space.Type: GrantFiled: May 29, 2014Date of Patent: June 16, 2020Assignee: DISCMA AGInventors: Frederick C. Beuerle, G. David Lisch, Jr., Richard Steih, Semen Kharchenko, Pankaj Kumar

Patent number: 10377073Abstract: A one-step hydraulic blow molding system and method for forming a preform and a liquid filled container from the preform. The machine and method include a sealing mechanism that forms a seal primarily utilizing compressive forces in an axial direction to prevent the leakage of liquid blow medium. The sealing mechanism includes an axial end face of a forming head and an upper axial surface of a neck ring.Type: GrantFiled: June 30, 2014Date of Patent: August 13, 2019Assignee: Discma AGInventors: G. David Lisch, Jr., Frederick C. Beuerle

Patent number: 6767197Abstract: A blow molding machine for producing a biaxially oriented, heat set plastic container, including a blow mold; a high-pressure gas source; a high-temperature gas source; a fluid source; a mixer coupled to the high-temperature gas source and to the fluid source; a blow core assembly having an exhaust; and a controller coupled to the high-pressure gas source, to the, high-temperature gas source, and to the fluid source. The PET containers produced by the machine have an average sidewall crystallinity greater than about 30%, which allows the PET container to maintain its material integrity during any subsequent pasteurization or retort process of the contents in the PET container, and during shipment of the PET container.Type: GrantFiled: December 28, 2001Date of Patent: July 27, 2004Assignee: Schmalbach-Lubeca AGInventors: Timothy J. Boyd, Kerry W. Silvers, Dwayne G. Valliencourt, G. David Lisch, Jr.

Patent number: 6763968Abstract: A plastic container for receiving a commodity and retaining the commodity during high-temperature pasteurization and subsequent cooling that includes an upper portion, a sidewall portion, and a base portion. The upper portion defines an aperture and is sealable with a closure. The sidewall portion, which defines a sidewall diameter, is connected to and extends generally downward from the upper portion. The base portion has a chime section connected to and extending generally downward and inward from the sidewall portion, and a push-up section connected to and extending generally upward and inward from the chime section to close the plastic container. The push-up section defines a push-up diameter, and the ratio of the sidewall diameter to the push-up diameter is at least 1.3:1.0.Type: GrantFiled: June 30, 2000Date of Patent: July 20, 2004Assignee: Schmalbach-Lubeca AGInventors: Timothy J. Boyd, Dwayne G. Vailliencourt, Kerry W. Silvers, Richard J. Steih, G. David Lisch, Jr.

Patent number: 6485670Abstract: A method for producing a biaxially oriented, heat set plastic container, including the steps of providing a plastic preform within a mold cavity; expanding and stretching the plastic preform into conformity with the surfaces defining the mold cavity to form a biaxially oriented plastic container; inducing crystallinity in the plastic container by using convection heat transfer to heat a surface of the plastic container to a temperature of at least 120° C.; and removing the plastic container from the mold cavity. The PET containers produced by the method have an average sidewall crystallinity greater than about 30%, which allows the PET container to maintain its material integrity during any subsequent pasteurization or retort process of the contents in the PET container, and during shipment of the PET container.Type: GrantFiled: November 9, 1999Date of Patent: November 26, 2002Assignee: Schmalbach-Lubeca AGInventors: Timothy J.
