Abstract: A slide fastener slider is disclosed as including spaced parallel wing members and a longitudinal axis therebetween, a pull-lug affixed to its top surface, a pull member operatively connected to said pull-lug for moving the slider relative to interlocking elements, with the pull member being movable parallel to the longitudinal axis, and ends on the pull-lug to exert a pulling force on the slider from below the top surface thereof.

Abstract: A foldable plastic slider having a pair of hinged wings that fold downwardly and secured permanently in place to the opposite sides of the slider body to attach it to the plastic reclosable fastener elements when manufacturing a thermoplastic bag. The wings are hinged at the top of the slider body to provide for ease in molding the slider using a simple 2-piece mold.

Abstract: A fluid-tight sealing slide fastener includes a pair of rows of coupling elements mounted respectively on inner opposite edges of a stringer tape, an elastomeric top stop mounted on the stringer tape around a terminal opening at ends of the rows of coupling elements, and a slider for taking the rows of coupling elements into and out of intermeshing engagement. The slider includes a slider body having a pair of upper and lower plates interconnected by a diamond, a presser having a plurality of pins extending through the upper plate, and a screw having a threaded shank threaded in a cylindrical body on the upper plate of the slider body and a head acting on the presser. When the slide fastener is closed and the screw is tightened, the pins are pressed against the top stop which is resiliently pressed against the lower plate and the diamond of the slider body to provide fluid-tight sealing between the top stop and the slider.
