Patent 9538817 was granted and assigned to YKK on January, 2017 by the United States Patent and Trademark Office.
Open-ended slide fasteners that are watertight and/or airtight. The slide fasteners include box and pin mechanisms integrated with the slide fastener and configured to compress the tape edges and create a water and air tight seal, thus eliminating the need for installing a separate component after the slide fastener has been manufactured.
