Patent number: 6037022Abstract: The specification discloses a polymer blend especially well-suited for coating paperboard substrates used in food packaging, particularly acidic or acid-generating foods such as fruit and vegetable juices. The blend contains an acid-activatable oxygen scavenger dispersed in a film-forming synthetic polymer such as an EVOH copolymer. When placed as a film or layer on the side of the substrate inside the container in contact with the food the blend is effective to reduce the oxygen in the container over time to a very low concentration, replacing the same with carbon dioxide, for an excellent preservative effect.Type: GrantFiled: September 16, 1997Date of Patent: March 14, 2000Assignee: International Paper CompanyInventors: Ashok M. Adur, Gerald A. Marano, Raymond A. Volpe, Henry L. Mei

Patent number: 5810243Abstract: A paperboard polymer coated carton having protected board raw edge surfaces for packaging food and non-food products is provided in which a thin slice of the inside carton raw edge surface is removed or skived away from the side seam flap. The thin slice includes all of the inside polymer layers and most of the paperboard. The resulting outside flap is folded into the carton inside over the paperboard raw edge surface, and is flame sealed to the inside polar polymer layer, to seal the paperboard raw edge surface. The sealed edge surface is then flame sealed to the inside of the opposite paperboard surface, thereby creating an additional inside-outside flame seal. By such a process only inside-outside seals are formed or polar-covalent seals.Type: GrantFiled: April 15, 1997Date of Patent: September 22, 1998Assignee: International Paper CompanyInventors: John M. DiPinto, Gerald A. Marano, Edward Bombolevich, Charles E. Gibbons

Patent number: 5452563Abstract: A method for substituting inert gas for ambient air in the headspace of a container prior to closing of an opening of the container. The container is displaced along a straight path in a predetermined horizontal direction from a first position to a second position, e.g., by a conveyor. A stream of inert gas is injected generally downward from an outlet toward the headspace via an inverted recess as the container travels from the first position to the second position along the path. The inverted recess has a peripheral edge which is a closed contour lying in a horizontal plane. The exit velocity of the inert gas at the outlet and the dimensions of the outlet are such that the flow of inert gas from the outlet into the headspace is generally laminar. A portion of the inert gas enters the headspace to displace gases inside the headspace until less than 1% oxygen remains in the headspace.Type: GrantFiled: June 30, 1994Date of Patent: September 26, 1995Assignee: International Paper CompanyInventors: Gerald A. Marano, Donald Evans, Edwin D. Lomax, James C. Harbison

Patent number: 5201165Abstract: A gas displacement device and method for substituting inert gas for ambient air in a gable-top paperboard carton prior to closing of an open top of the carton. The open top has first and second predetermined dimensions in mutually perpendicular directions. The device includes a source of inert gas, a channel for outputting a blanket of inert gas through an outlet and a conveyor for moving cartons in the first direction so that each open top passes under the outlet. The outlet has maximum dimensions in first and second mutually perpendicular directions which are respectively greater than the first predetermined dimension and less than the second predetermined dimension. The open top of the carton passes underneath the outlet with the directions of the first and second predetermined dimensions being oriented substantially parallel to the first and second directions respectively. The outlet has the shape of a rectangle with rounded corners.Type: GrantFiled: September 16, 1991Date of Patent: April 13, 1993Assignee: International Paper CompanyInventors: Gerald A. Marano, Donald Evans, Edwin D. Lomax, James C. Harbison

Patent number: 4983431Abstract: The present invention relates to an improved container for food and non-food products. The container utilizes a novel paperboard barrier laminate structure which maintains an isolated gas environment in the container. The laminate makes use of a high strength, heat-resistant and caulking polymer layers which prevent pinholes, cuts, or cracking of the barrier layers during blank conversion, package formation, and package distribution. In addition, the novel polymer resin layers act to caulk the seams and channels present in the carton providing a sealed leak free container.Type: GrantFiled: May 22, 1989Date of Patent: January 8, 1991Assignee: International Paper CompanyInventors: Charles E. Gibbons, Gerald A. Marano, James M. Kittrell, Allan A. Whillock, Robert L. Lanham, Donald Evans
