ABSTRACT:
A plastic reclosable fastener with slider for opening and closing the reclosable fastener on plastic-film bags and the like is disclosed. The plastic reclosable fastener and slider include a provision for restraining the slider in closed position and thereby maintaining the male and female elements of the fastener in interlocking relation to avoid inadvertent opening of the elements of the fastener when the slider reaches the fully closed position at the end of its travel along the fastener. The ends of the flanges of the fastener that are created by the slider-restraining notch are provided with diverging structure to facilitate re-entry of the slider separator structure between the flanges when the slider is moved toward the opposite end of the fastener to open the male and female elements of the fastener.
