Abstract
The present disclosure relates to a leakproof or leak-resistant slider zipper for reclosable packages or bags wherein the zipper profiles include upper flanges which are captured within horizontal channels of the slider. The horizontal channels are configured to be closer to each other at the closing end than at the opening end so as to urge the zipper profiles together at the closing end and apart at the opening end. The zipper profiles further include complementary interlocking elements as well as a lower bead and flap configuration wherein the flap remains urged against the bead in a leakproof or leak-resistant configuration throughout the entire length of the slider.

A zipper for a reclosable package or bag, comprising:
- a first zipper profile with a first interlocking element, a first flange and a first leak-resistant element;
- a second zipper profile with a second interlocking element, a second flange and a second leak-resistant element;
- and
- a slider including first and second channels capturing the respective first and second flanges above the first and second interlocking elements whereby the first and second interlocking elements are below the first and second channels, the slider including an opening end wherein the channels are spaced apart so as to separate the first and second zipper profiles and a closing end wherein the channels are spaced apart so as to interlock the first and second zipper profiles, whereby when the slider is moved in a first direction, the first and second zipper profiles are interlocked with each other and when the slider is moved in a second direction, the first and second zipper profiles are separated from each other;
- the slider further including first and second side walls which include tapered portions to maintain contact between the first leak-resistant element and the second leak-resistant element throughout an entire length of the slider.
