Abstract
A slider-zipper assembly in which the slider has a design lending itself to economical manufacture using an injection molding process. The slider comprises a frame that straddles the zipper, a plow supported by the frame and separating respective sections of two interlockable profiled zipper parts, and a plurality of projections that latch under the zipper parts to retain the slider on the zipper. The frame has three bridging members, a first opening disposed between the first and second bridging members, and a second opening disposed between the second and third bridging members, the plow being connected to and depending downward from the second bridging member. First and second retaining projections are disposed entirely under the first opening with no portion of the first and second bridging members overhanging any portion thereof, and third and fourth retaining projections are disposed entirely under the second opening with no portion of the second and third bridging members overhanging any portion thereof.
