Patent ID: 7670052

Claim:
A slider and zipper assembly, the slider having a leading edge, a trailing edge and a top edge with a top surface and a top frame, comprising: a pair of protrusions at the trailing edge pressing on opposite sides of a zipper of the slider and zipper assembly to close the zipper upon moving the slider over the zipper in a closing direction, and an opening plow on the top surface and protruding downward between the leading edge and the trailing edge, wherein the top surface is positioned such that it originally projects upward from the top frame, and wherein the top surface is depressed downward for the opening plow to penetrate a pair of inter-locked inter-locking members on the opposite sides of the zipper, and for the opening plow to separate the pair of inter-locking members and open the zipper by moving the slider over the zipper in an opening direction while the top surface is being depressed downward, and wherein when the top surface is not depressed downward, the top surface tends to return to its original upwardly projecting position.
