A plastic bag closer slider has a separator normally resting in notches in the tops of slider track strips, when the slider is at a bag-closed stop. As the slider is moved in the bag-opening direction, the separator is cammed downward by ends of the notches to disengage interlocking profile features and open the tag. In another embodiment, notches are omitted. The separator is manufactured with a normally down position but is resiliently biased upward when the bag is closed. As the slider is moved in the bag-opening direction, the pointed end of the separator wedge descends between the strips to open the bag. When the slider is moved in the bag-closing direction, the separator is cammed upward by the drag of the strip tops and the tapering walls of the slider squeeze interlocking profile features together, closing the bag.

[ What is claimed is:] [1.] In a reclosable bag having first and second walls and an open top defined by first and second elongate flexible strips attached to the first and second walls, respectively, adjacent the top of the walls, one of the strips having a profile portion forming a groove and the other strip having a profile portion forming a rib with a portion of the rib received and retained in the groove when the bag top is closed, each of the strips having a base connected to the respective wall and each of the strips having an upper edge adjacent the upper edge of the other strip, and the bag having a slider mounted on the strips and movable in one direction longitudinally of the strips to progressively separate the rib from the groove to open the bag, and the slider being movable in the opposite direction to progressively return the rib portion to retained condition in the groove to close the bag, and the slider having a top, the improvement comprising:a separator movably situated in the slider and having a proximal portion adjacent the top of the slider and hinged to the slider and having a distal portion residing in a first space between the top of the slider and the upper edges when the rib portion is retained in the groove of the groove-forming profile;the separator distal portion being movable from the first space into position between the rib and the groove to separate the rib from the groove as the slider moves in the one (bag-opening) direction, but movable out of position between the rib and the groove as the slider is moved in the opposite (bag-closing) direction to permit closure of the bag.
