High burst leak-resistant slider zipper system

摘要

The disclosure pertains to a slider zipper which includes first and second zipper profiles, typically a hinged profile and an non-hinged profile, with first and second ears extending above the respective first and second zipper profiles. A slider rides above the zipper profiles and opens the zipper by separating the ears. Typically, the slider is configured to push the non-hinged zipper profile away from the hinged zipper profiles. Similarly, typically, the ear on the non-hinged zipper profile is stiffer than the ear on the hinged zipper profile.

主权项

1. A leak-resistant zipper for a reclosable package, including:
a first zipper profile including a first interlocking element and a first flange, and further including a first ear portion extending therefrom; a second zipper profile including a second interlocking element and a second flange, and further including a second ear portion extending therefrom, wherein the second interlocking element is in a hinged relationship with the second flange, and wherein the first ear portion is stiffer than the second ear portion; a slider including a plow between the first and second ear portions, the plow entirely above the first and second interlocking elements for separating the first and second interlocking elements from each other engaging the first and second ear portions, the slider separating the first and second ear portions, thereby separating the first and second interlocking elements from each other, when moved in a first direction, the slider urging the first and second ear portions toward each other, thereby interlocking the first and second interlocking elements, when moved in a second direction; and the first ear portion including a gap for forming a parking station for the slider, and wherein the second ear portion is free of a gap for forming a parking station.
