<p>The present disclosure relates to a leakproof or leak-resistant slider zipper (10) for reclosable packages or bags wherein the zipper profiles (12, 14) include upper flanges (36, 38) which are captured within horizontal channels (76, 78) of the slider (16). 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 (20, 22) as well as a lower bead (46) and flap configuration (44) wherein the flap remains urged against the bead in a leakproof or leak-resistant configuration throughout the entire length of the slider.</p> |
