The container comprises a mouth, a wall section which adjoins the mouth in a longitudinal direction (L) of the container, and a base section which is designed as a standing face. The wall section merges into the base section. The container is formed in one piece. The base section has an injection point located in the interior in a radial direction (R) with respect to the longitudinal direction (L), and a central region which surrounds this injection point, and also a transition section which extends from the central region to the wall section. The transition section has a curvature with a finite radius of curvature in at least one and preferably in every radial direction (R) of the container in every geometric sub-section.Type: GrantFiled: August 21, 2008Date of Patent: February 7, 2012Assignee: Krones AGInventors: Heinrich Deyerl, Gerhard Schuster, Bastian Tissmer

Patent number: 8096098Abstract: Method and system for handling a plurality of hot-filled and capped containers having temporary deformations or distortions caused by vacuums induced in the containers. For each container, temporary deformations are confined or directed to a particular portion of the container. Annular hoop rings can be provided to confine the temporary deformations to a smooth sidewall portion of the container between the annular hoop rings. Alternatively, one or more supplemental vacuum panels can be provided to confine or direct the temporary deformation thereto. The annular hoop rings and the one or more supplemental vacuum panels can provide for substantially stable touch points for the container. The containers are conveyed with temporary deformations such that substantially stable contact points of each container are in contact with corresponding substantially stable contact points of other containers.Type: GrantFiled: January 2, 2010Date of Patent: January 17, 2012Assignee: Graham Packaging Company, L.P.Inventors: Paul V. Kelley, Scott E. Bysick

Patent number: 8047388Abstract: A plastic container of the type that may be formed from a material such as PET using the stretch blow molding process includes a main body portion and a base portion that is characterized by a relatively tall and narrow profile above the standing ring and that has a deep inset recess defined therein. The deep inset recess is defined in part by an upstanding inner sidewall portion adjacent to the standing ring that has a height that may be greater than about 0.35 inch. The upstanding inner sidewall portion may have a substantially straight portion that is substantially parallel to a substantially straight portion of an outer sidewall of the base.Type: GrantFiled: December 8, 2008Date of Patent: November 1, 2011Assignee: Graham Packaging Company, L.P.Inventors: Paul V.

Patent number: 8020717Abstract: Molded preform for blow molding a plastic container for pressurized applications, the preform having a base with a multilayer wall for forming a delamination and crack resistant multilayer footed container base. The preform base forming region has an end cap portion with a non-spherical inner wall, including a flattened central section joined by arcuate corner sections to a generally cylindrical outer section. The inner wall sections provide a varying end cap thickness profile which enhances orientation in select portions of the footed container base for improved performance and/or lightweighting of the container base.Type: GrantFiled: April 19, 2007Date of Patent: September 20, 2011Assignee: Graham Packaging Company, LPInventor: Tapan Y. Patel

Patent number: 7980404Abstract: A container can have a body with an integrally formed base attached to the body. The base includes a concave annular wall extending from the container sidewall to a standing surface, and an inner wall extending from the standing surface to a substantially flat inner annular wall. The inner annular wall is recessed in the base and is substantially perpendicular to the container sidewall. The inner annular wall includes a centrally located dimple. The dimple includes a plurality of spaced apart and radially extending indented ribs. One or more of the ribs extend radially into a brace that tapers to meet the inner annular wall.Type: GrantFiled: March 18, 2009Date of Patent: July 19, 2011Assignee: Graham Packaging Company, L.P.Inventors: Greg Trude, John W.
