<p>A slider (121) to open and close a plastic bag (113) has a separator (134, 136) in a rest position at the tops (118T, 119T) of interlocking rib and groove profiled bag-closure strips, when the slider is in a bag-closed stop location. As the slider is moved in the bag-opening direction, the separator pivots downward to disengage the interlocking profile features (18H, 19G), and open the bag. When the slider is moved in the bag-closing direction, the separator is cammed upward by the strip tops until it rides atop the strips, and the tapering walls (31, 32) of the slider squeeze the interlocking profile features together, closing the bag. A guide pin (141) in the slider pre-conditions the strips for the opening separator and helps guide the slider as the bag is opened. It is also a slider travel stop if needed at the strip ends.</p> |
