Patent number: 9987787Abstract: A method and system for hydraulic blow molding a container from a preform 24. A molding medium is injected into the preform from a nozzle 12 during a first molding stage. In the first molding stage, the molding medium is injected so as to be specifically directed at a closed end of the preform 24. During the first molding stage, the preform is axially stretched in response to the force exerted on the preform by the molding medium. The molding medium is also injected into the preform during a second molding stage, where the molding medium is injected at a flow rate greater than a flow rate during the first molding stage. During the second molding stage, the preform is radially expanded into the shape of the container.Type: GrantFiled: June 28, 2013Date of Patent: June 5, 2018Assignee: DISCMA AGInventors: G.

Patent number: 9221223Abstract: A method of forming a container includes providing a preform of the container. The preform has a wall with an interior region and an exterior region. The method also includes disposing the preform in a mold cavity wherein the mold cavity has a mold surface. Furthermore, the method includes introducing a substance into the preform to expand the preform toward the mold surface. The interior region of the wall has a first interior temperature prior to the introduction of the substance and a second interior temperature after the introduction of the substance. The exterior region of the wall has a first exterior temperature prior to the introduction of the substance and a second exterior temperature after the introduction of the substance. The method further includes controlling the first interior temperature to be greater than the first exterior temperature prior to the introduction of the substance.Type: GrantFiled: December 20, 2012Date of Patent: December 29, 2015Assignee: Discma AGInventors: G.

Patent number: 9044887Abstract: A method of forming a plastic container from a preform. The method comprises injecting a forming liquid into the preform at a predetermined system pressure range, a predetermined flow rate, and a predetermined duration sufficient to create a pressure spike at a peak pressure. The peak pressure being greater than the system pressure to urge the preform into the mold cavity, thus creating enhanced container definition, reduced post mold shrinkage, lower residual material stresses, and/or an improved transfer of the mold geometry and engraving to the final formed container.Type: GrantFiled: May 23, 2012Date of Patent: June 2, 2015Assignee: DISCMA AGInventors: Robert A.

Patent number: 8573964Abstract: An apparatus and method for simultaneously forming and filling a plastic container is provided. A mold cavity defines an internal surface and is adapted to accept a preform. A pressure source is a servo motor system that includes an inlet. The servo motor system is operable to draw liquid through the inlet and urge it into the preform. A blow nozzle may be adapted to receive the liquid from the pressure source and transfer the liquid at high pressure into the preform thereby urging the preform to expand toward the internal surface of the mold cavity and create a resultant container. The liquid remains within the container as an end product.Type: GrantFiled: October 18, 2010Date of Patent: November 5, 2013Assignee: Amcor LimitedInventors: David Andison, George David Lisch, Kirk Edward Maki, Theodore F.
