Abstract
The water-resistant or waterproof zipper includes first and second profiles which are interlocked or separated by the movement of a slider. The first sidewall of the slider is generally planar while the second sidewall is generally curved so that the sidewalls are relatively closer together at the closing end and generally further apart at the opening end. A triangular island and separating plow are formed at the opening end to separate the first and second profiles. The slider includes various channels which engage corresponding rails in the profiles in order to properly position the profiles. The slider further includes various protrusions and a flange to properly position the profiles.
