Publication number: 20080159664Abstract: A reclosable bag that can be hermetically sealed. The bag comprises a pair of zipper strips that are joined in respective zones without substantial deformation of the longitudinal profiled closure elements. These zones of zipper strip joinder assist in providing a leakproof transition from the openable section of the zipper to the corner seals, where the longitudinal profiled closure elements are either substantially deformed (e.g., crushed) or absent. The method of manufacture involves the steps of ultrasonically welding a wide area and then thermally crushing a narrower area overlapping the wide welded area to form leakproof zipper joints. This method can be applied to string (flangeless) zippers as well as flanged zippers.Type: ApplicationFiled: March 12, 2008Publication date: July 3, 2008Inventors: Lawrence Share, David J. Matthews, Donald L. Crevier

Publication number: 20080159663Abstract: A reclosable bag comprising a receptacle having a mouth, a flexible closure located near the mouth, and a slider mounted over the mouth. The receptacle comprises first and second panels and first and second seals at respective ends of the mouth. The closure comprises first and second closure profiles. The slider comprises a finger that extends into the mouth, but not between the first and second closure profiles. The slider may be of a type that causes disengaged portions of the first and second closure profiles to mutually engage during travel in either direction. The finger prevents the slider from being pulled off either end of the closure by abutting the corresponding seal. The receptacle and closure may form an airtight boundary for an interior volume.Type: ApplicationFiled: December 29, 2006Publication date: July 3, 2008Inventor: Linh Pham

Publication number: 20080112652Abstract: The present disclosure relates to a zipper for a reclosable package or bag and a method of forming thereof, wherein aligned apertures are cut into the zipper flanges proximate to the slider position when the package or bag is open. Portions of the front and rear walls of the package or bag extend through these apertures during the original manufacture of the bag, and are sealed to each other during the same sealing operation which seals the front and rear walls of the package or bag to the flanges of the zipper. The resulting seal between the front and rear walls, extending through the apertures in the zipper flanges, prevents the zipper profiles from opening in the portion where the slider is positioned when the reclosable package or bag is open.Type: ApplicationFiled: November 9, 2006Publication date: May 15, 2008Inventor: Kevin P.
