摘要

The present disclosure relates to a leak-resistant slider zipper. The zipper typically includes end seals at the opening and closing ends of the zipper, an upper and a lower set of interlocking elements, first and second upper flanges above the upper interlocking elements having no gaps or cut-outs therein, and first and second lower flanges below the lower interlocking elements, one of the lower flanges being folded back on itself, and a slider.

主权项

1. A slider zipper, including:
a first profile with a first upper interlocking element, a first lower interlocking element, a first upper flange, and a first lower flange; a second profile with a second upper interlocking element, a second lower interlocking element, a second upper flange and a second lower flange, the second lower flange being folded back on itself; the first and second upper flanges being continuous; the first profile and the second profile being joined together at an opening end seal and a closing end seal; a slider having an opening end and a closing end, a first side and a second side, a bottom including inwardly facing ribs to maintain the slider on the first and second zipper profiles, and a top having a wedge formed from diverging slots positioned to engage the first and second upper flanges; wherein when the slider is moved in an opening direction the wedge forces apart the first and second upper flanges, thereby separating the first and second upper interlocking elements and the first and second lower interlocking element and when the slider is moved in a closing direction, the slider presses together and fully interlocks the first and second upper interlocking elements and the first and second lower interlocking elements; wherein a width of the slider wedge is 2½ to 3½ times the width of the interlocking elements when measured between outside surfaces of the interlocking elements.
