Abstract:
1. A slider body comprising: a top plate; a bottom plate substantially parallel to the top plate, the bottom plate having lateral upwardly projecting bottom side rails, the bottom side rails having an upper surface vertically spaced from a lower surface of the top plate by a first elevational distance; and a post extending from the upper surface of the bottom plate to the lower surface of the top plate, the post to facilitate closing of a zipper when the slider body is moved in a first direction and opening of the zipper when the slider body is moved in a second direction opposite the first direction; and a downwardly projecting top control rib that extends from the lower surface of the top plate and is disposed in the second direction from the post, wherein the downwardly projecting top control rib includes an edge or face that is disposed at an angle away from the lower surface of the top plate to provide a gap between the post and the top control rib in the second direction that is longer at a lower portion of the top control rib than at an upper portion of the top control rib, wherein the slider body is configured to accommodate passage of a zipper tape and an overlying layer in a slot defined by a space between the top plate and the upper surface of the bottom side rails, and wherein the downwardly projecting top control rib extends into the slot and is configured to separate first and second portions of the overlying layer to facilitate opening or closing of the zipper by the slider body.
