Patent number: 10035625Abstract: A reclosable gusseted bag is disclosed wherein a single web multiple alignment zipper is placed around the interior of the mouth of the bag, downwardly adjacent from the upper edge of the front panel, rear panel and side gussets thereby resulting in an increased size of opening as the mouth of the gusseted bag. The use of a single web multiple alignment zipper allows opposing portions of the web to engage each other within a range of alignments thereby allowing for simplified use by the consumer.Type: GrantFiled: July 31, 2017Date of Patent: July 31, 2018Assignee: ILLINOIS TOOL WORKS INC.Inventors: Charles G. Greco, Steven Ausnit

Patent number: 9260225Abstract: The disclosure relates to a zipper for a reclosable bag wherein the zipper is designed to make additional sound during operation, and further provide an increased tactile response. The zipper profile is manufactured by forming cuts in the profile, and then the profile is stretched so that the cuts become gaps. These gaps cause additional sound during operation of the zipper.Type: GrantFiled: November 29, 2011Date of Patent: February 16, 2016Assignee: ILLINOIS TOOL WORKS INC.Inventors: David Anzini, Rusty Koenigkramer, Eric Plourde, Kenny McCracken, Steven Ausnit, Charles G.

Patent number: 8550715Abstract: A reclosable zipper is illustrated, which includes a first profile having a first interlocking element, a first consumer side flange with a first consumer side intermeshing contour and a first product side flange with a first product side intermeshing contour. The zipper includes a second profile which includes a second interlocking element, a second consumer side flange with a second consumer side intermeshing contour, and a second product side flange with a second product side intermeshing contour. The first and second consumer side intermeshing contours are complementary intermeshing contours and the first and second product side intermeshing contours are complementary intermeshing contours. As a result, when the interlocking elements are engaged, the first and second consumer side intermeshing contours are capable of intermeshing and the first and second product side intermeshing contours are capable of intermeshing.Type: GrantFiled: November 22, 2010Date of Patent: October 8, 2013Assignee: Illinois Tool Works Inc.Inventors: David J. Anzini, Charles G. Greco, Glyn Russell

Patent number: 8250718Abstract: The disclosure relates to a reclosable zipper for a package or bag wherein apertures are formed at periodic package-width intervals passing through the interlocking elements of the zipper profiles in order to minimize the mass of zipper material in areas where side seals of packages or bags will be subsequently formed. The otherwise interlocking elements upstream of, or at the trailing edge of, the apertures are deformed so as to prevent interlocking of the elements through a limited area. This allows a separator pin to pass through the area of the apertures and pass between the zipper profiles, eliminating or reducing the collision of the separator with the zipper profiles and subsequent potential damage to the zipper profiles.Type: GrantFiled: September 18, 2009Date of Patent: August 28, 2012Assignee: Illinois Tool Works Inc.Inventor: Charles G. Greco

Publication number: 20120202667Abstract: The disclosure pertains to method for manufacturing reclosable packages, bags or pouches wherein, typically, a unisex zipper is looped and sealed inside of the package. The formation of the looped zipper segment causes the package to have a wide open mouth, and a natural tendency toward the open configuration. Both transverse and machine direction methods are disclosed, as well as resulting packages which may include a spout.Type: ApplicationFiled: July 28, 2011Publication date: August 9, 2012Applicant: ILLINOIS TOOL WORKS INC.Inventors: Charles G.

Patent number: 7540072Abstract: The use of coextruded or integral sealing ribs on zipper flanges enhances the quality of the sealing between the flanges and the walls of a reclosable package. The coextruded sealing ribs may be made from sealing resins or similar materials. Additionally, grip strips are placed on the opposite side of the flanges from the ribs in order to improve the quality of the sealing even further and to inhibit inner flange sealing.Type: GrantFiled: June 26, 2006Date of Patent: June 2, 2009Assignee: Illinois Tool Works Inc.Inventors: David J. Anzini, Charles G. Greco, Rusty Koenigkramer, Glyn Russell, Lawrence Share
