Patent number: 7416089Abstract: An improved hot-fill type container that has particular utility for use with the nitrogen dosing hot-fill process includes a finish portion, a main body portion and a base portion having a pushup area and a chime that is situated about the pushup area for supporting the container when a horizontal surface. The container advantageously includes a reinforced heel portion in the area between the main body portion and the chime for protecting the container against deformation that could otherwise be caused by the positive pressurization of the nitrogen dosing process.Type: GrantFiled: December 6, 2004Date of Patent: August 26, 2008Assignee: Constar International Inc.Inventors: Richard G. Kraft, Prasad Joshi, Phillip Kraft

Patent number: 6698606Abstract: A blow-molded plastic container is provided suitable for hot-filling under pressurize-fill conditions, and under gravity-fill conditions. The container includes opposing handgrips within panels, which lack hinges and thus do not function as conventional vacuum panels as the inward deformation is spread beyond the panels. The hand grip includes a distal, relatively stiffened portion formed by a sidewall that forms a thumb piece and a proximal, relatively un-stiffened portion the smooth merges into a cylindrical sidewall of the container.Type: GrantFiled: June 4, 2002Date of Patent: March 2, 2004Assignee: Constar International, Inc.Inventors: Donald Deubel, Satya Kamineni, Philip G. Kraft, Richard G. Kraft

Patent number: 6645423Abstract: In a process for making a multi-chambered container that is lightweight, relatively inexpensive to produce, and that requires less external reinforcement against flexure than conventional multi-chambered containers do, a parison is heated and inflated to form the container. Further, first and second pinched-in areas are fashioned in the sidewall of the container. The first pinched-in area includes first and second wall portions that extend inwardly toward an interior of the main body of the container, and a first end wall portion connecting the first and second wall portions. The second pinched-in area includes third and fourth wall portions that extend inwardly toward an interior of the main body, and a second end wall portion connecting the third and fourth wall portions.Type: GrantFiled: March 25, 2002Date of Patent: November 11, 2003Assignee: Constar International, Inc.Inventors: C. Joseph Everette, Charles M. Brandt, Richard G. Kraft

Patent number: 6070753Abstract: A container holds fluids, such as motor oil, and is sized to hold about one quart or one liter. The container has a rectangular base portion, and a top portion is formed integral with the base portion, the top portion being shaped like an offset, inverted funnel. The top portion has an opening forming a mouth, an outside edge of the mouth being in substantial alignment with a first side of the base portion. A concave, arcuate top panel extends from an opposing second side of the base portion to the mouth, and the top panel has a ridge along the center of its length for increasing top load strength and for providing a flow channel for fluid within the container.Type: GrantFiled: February 2, 1998Date of Patent: June 6, 2000Assignee: Exxon Research and Engineering Co.Inventors: Richard N. Hirst, Herbert M. Meyers, Richard C. Edstrom, Richard G. Kraft

Patent number: 5971197Abstract: A plastic container that has more than one chamber and that is constructed so as to be stiffer than conventional molded multi-chambered containers includes a bottom wall, a neck, and a main body that has defined therein a first pinched-in area and a second pinched-in area that extends inwardly toward and is joined to the first pinched-in area so as to define separate compartments. The first end wall portion is laterally offset from the second end wall portion, so that the flexibility of the main body about the joint of the first and second wall portions is minimized. As a result, the container is less likely to need supplemental reinforcement against flexure.Type: GrantFiled: February 28, 1997Date of Patent: October 26, 1999Assignee: Crown Cork & Seal Technologies CorporationInventors: C. Joseph Everette, Charles M. Brandt, Richard G. Kraft
