Patent number: 7469796Abstract: A plastic container (10) that exhibits an optimal ratio of hoop strength to top load strength includes a finish portion (12) and generally cylindrical main body portion (14). The main body portion includes a sidewall (16) that has a first plurality of generally vertical ribs (18, 20, 21, 24) defined therein. In addition, a second plurality of generally horizontal wave (26, 28, 30, 32, 34, 36) shaped ribs is defined in the sidewall. The generally horizontal wave shaped ribs intersect with the generally vertical ribs, thereby imparting enhanced strength characteristics to the container (10).Type: GrantFiled: November 5, 2003Date of Patent: December 30, 2008Assignee: Constar International Inc.Inventors: Satya Kamineni, Michael Mooney

Patent number: 7458478Abstract: A hot fillable container includes a bottom and a sidewall connected with the bottom so as to define an internal space. The sidewall is further shaped so as to define in transverse cross-section a first convex sidewall label area having a first convexly curved outer surface having a first curvature and a second convex sidewall area having a second convexly curved outer surface having a second curvature. The label area is of the type that has no horizontal reinforcing ribs. The sidewall is constructed and arranged so that deformation of the sidewall in response to a partial vacuum condition within the internal space after a hot fill process will result in a decrease of the first curvature and an increase of the second curvature. This deformation is effected without any denting of the sidewall.Type: GrantFiled: January 17, 2007Date of Patent: December 2, 2008Assignee: Constar International Inc.Inventor: Satya Kamineni

Patent number: 7416090Abstract: An improved hot fillable container includes a bottom and a sidewall connected with the bottom so as to define an internal space. The sidewall is shaped so as to define in transverse cross-section in at least one location a substantially circular outer circumference. The sidewall further includes first and second convex label panel portions each having a convexly curved outer surface. Advantageously, the sidewall is constructed and arranged so that deformation of the sidewall in response to a partial vacuum condition within the internal space will occur primarily in the convex label panel portions. The structure permits the hot fillable container to be constructed without the use of concave vacuum panel portions.Type: GrantFiled: October 8, 2004Date of Patent: August 26, 2008Assignee: Constar International Inc.Inventors: Michael Mooney, Satya Kamineni
