US Patent:

7017241, Mar 28, 2006
Filed:

Aug 26, 2002
Appl. No.:

10/228355
Inventors:

Per Bentsen - Suffern NY, US
Assignee:

Illinois Tool Works Inc. - Glenview IL
International Classification:

A44B 19/16
US Classification:

24400
Abstract:

A slider that reduces the tendency of a slider-zipper assembly to deactivate under freezer conditions. One embodiment of the slider comprises an opening window comprising a top portion, first and second side portions respectively connected to opposing ends of the top portion of the opening window, and a keeper connected to and projecting downward from the top portion, the keeper being disposed closer to the first side portion than to the second side portion of the opening window; a closing window comprising a top portion, and first and second side portions respectively connected to opposing ends of the top portion of the closing window, the closing window being separated from the opening window by a central zone; and a pair of opposing ridges located in the central zone proximal to the opening window and comprising respective convex surface of curving form. The ridges cam the profiled closure members of the zipper together and cam the male-profiled closure member toward the keeper.

US Patent:

7223222, May 29, 2007
Filed:

Jul 1, 2005
Appl. No.:

11/173581
Inventors:

David J. Anzini - Farmington NY, US
Steven Ausnit - New York NY, US
Lars Wihlborg - Stratford CT, US
Per Bentsen - Suffern NY, US
Robert G. Kobetsky - Chicago IL, US
Assignee:

Illinois Tool Works Inc. - Glenview IL
International Classification:

B31B 1/90
US Classification:

493214, 493212, 493213, 493927, 531334, 531392, 53412
Abstract:

The present disclosure relates to methods for forming reclosable bags with slider zippers which can be used in high pressure pasteurization. In particular, these methods form reclosable bags with a shroud formed over the slider zipper, with a patch or cap for protecting the slider during high pressure pasteurization. When the user tears the shroud from the bag, the patch or cap remains attached to the shroud but releases from the slider. An alternative embodiment forms an air pocket in the shroud to protect the slider.

US Patent:

7524110, Apr 28, 2009
Filed:

Apr 12, 2005
Appl. No.:

11/103751
Inventors:

David J. Anzini - Farmington NY, US
Steven Ausnit - New York NY, US
Michael J. Lasofsky - Pomona NY, US
Lars Wihlborg - Stratford CT, US
Per Bentsen - Suffern NY, US
Robert G. Kobetsky - Chicago IL, US
Assignee:

Illinois Tool Works Inc. - Glenview IL
International Classification:

B65D 33/14
B65D 33/16
B65D 33/00
US Classification:

383 5, 383 612, 383 64, 383204
Abstract:

The disclosure relates to a semi-soft cap or patch which is secured by adhesive to a slider on a zipper in a reclosable package. This cap or patch prevents the slider from puncturing the web or film of the bag during high pressure pasteurization. Further, the cap or patch is secured to a tear-away header which is formed as a shroud over the zipper. This allows the user to tear off the header which likewise removes the cap or patch from the slider. The header, with the cap or patch still attached thereto, can thereafter be disposed of as a single piece.

End Stops For Zippers For Reclosable Packages

US Patent:

7882603, Feb 8, 2011
Filed:

Oct 10, 2007
Appl. No.:

11/973703
Inventors:

Per Bentsen - Suffern NY, US
Assignee:

Illinois Tool Works Inc. - Glenview IL
International Classification:

B65D 33/16
US Classification:

24436, 383 64
Abstract:

The end stop is formed on ends of a zipper for a reclosable package or bag by ultrasonically welding the ends of the zipper profiles together so as to form a raised portion. This prevents the slider from being pulled off of the ends of the zipper. Additionally, in the ultrasonic welding step, an indentation is formed into which glue is added thereby forming a lateral protrusion on the side of a zipper profile. This increases the strength of the end stop and increases the slider pull-off force which can be resisted.

US Patent:

20060277737, Dec 14, 2006
Filed:

Jun 8, 2005
Appl. No.:

11/147559
Inventors:

David Anzini - Farmington NY, US
Steven Ausnit - New York NY, US
Lars Wihlborg - Stratford CT, US
Per Bentsen - Suffern NY, US
Robert Kobetsky - Chicago IL, US
International Classification:

B21F 45/18
US Classification:

029409000, 029408000
Abstract:

The disclosure pertains to methods for inserting a soft cap onto a slider in order to protect the slider from damaging the package film of a reclosable bag during high pressure pasteurization. A first embodiment discloses manual or automated insertion of the soft cap onto the slider, prior to inserting the slider/cap assembly onto a length of zipper. A second embodiment discloses automated insertion of the soft cap onto a slider which is already mounted on a length of reclosable zipper. A third embodiment uses an insert molding process with a first mold cavity to form the slider and a second mold cavity to form the soft cap over the slider. A fourth embodiment uses a dual shot molding process in a single mold cavity to form both the slider and the soft cap thereover.

Filed:

Apr 18, 2006
Appl. No.:

11/405786
Inventors:

Per Bentsen - Suffern NY, US
International Classification:

A44B 19/36
US Classification:

024399000, 024436000
Abstract:

A zipper for a reclosable bag is disclosed, wherein the end stops of the zipper are formed with a dot of hot glue or adhesive. These end stops are designed to limit the range of travel of the slider and prevent the slider from being removed from the zipper. Additionally, a vertical wall facing the slider is formed to prevent the slider from riding over the end stop.
