Publication number: 20090202766Abstract: Accordingly, the present disclosure provides a container and method of making a container. In one example, a preform is disposed into a mold cavity having a base forming assembly. The base forming assembly includes a base insert and a movable ring insert. The preform is blown against the mold cavity to form a body defining a base portion. The movable ring insert is advanced into the base portion to form a thinned flex point in the base portion while keeping the base insert fixed. The container is hot-filled with a commodity. The commodity is allowed to cool causing a vacuum in the container that results in the upward movement or inversion of a central inset portion defined at the thinned flex point.Type: ApplicationFiled: February 6, 2009Publication date: August 13, 2009Applicant: Amcor LimitedInventors: Frederick C.

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.

Patent number: 6709624Abstract: A method and apparatus for stabilizing a blow molded plastic preform and container in a blow mold during a demolding operation. The blow mold has a first mold section, a second mold section, and a mandrel. The mandrel cooperates with a pair of spring loaded jaws slidingly coupled to one or both of the mold sections. With the mold sections in their fully open position, the mandrel with an attached preform and/or container travels into the blow mold. During the final stage of closing the mold sections, the jaws contact the finish and restrain the container. As the mold sections begin to open, the jaws prevent any movement of the container relative to the mandrel.Type: GrantFiled: July 19, 2001Date of Patent: March 23, 2004Assignee: Schmalbach-Lubeca AGInventors: G.

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.
