摘要

Multifunctional zip fastener with combined opening methods comprises four sliders mounted on the zip fastener. The four sliders all sit on the same zip fastener spiral and can all be guided over the entire path of the spiral. The sliders are integrated head-to-head or foot-to-foot so that the sliders always have opposite functions when moved in the same direction, e.g. slider (1) in one direction closes the zip fastener, slider (2) in the same direction opens the zip fastener, slider (3) in the direction re-closes the zip fastener, and slider (4) in the same direction re-opens the zip fastener.
