ABSTRACT:
A slider-zipper assembly includes a zipper having two interlockable zipper parts and a slider mounted to said zipper, one or both of the zipper parts having a longitudinal channel with closed ends and a substantially constant profile between the closed ends. The slider causes confronting portions of said the zipper parts to engage during slider travel in a first direction and to disengage during slider travel in a second direction opposite to said first direction. The slider comprises a pair of projections or a single extended projection arranged to project into and travel along the longitudinal channel during slider travel. One closed end of the channel lies in the path of one of the two projections or one end of the extended projection when the slider travels in an opening direction. The other closed end of the channel lies in the path of the other of the two projections or the other end of the extended projection when the slider travels in a closing direction. The closed ends of the channel act as slider end stops, blocking further travel of the slider.
