ABSTRACT:
A flexible reopenable slide closure structure having first and second flexible plastic continuous fastener strips each having at least three continuous coactingly shaped interlocking releasable rib and groove elements extending along the strip with a closure slider positioned on the strips and guided to move therealong in a closing direction with the slider having opposing faces for pressing the strips together, one of the faces having a raised ridge extending laterally across the strip and extending at an angle to the direction of the strips so that the strips are pressed together in such a way that the ribs and grooves at one side are interlocked first with the ribs and grooves at the center second and the ribs and grooves at the other side last so that the ribs and grooves do not laterally fight each other while moving to closing relationship.
