Reißverschluß mit führungssicheren Rippen

摘要

A resilient fastener or zipper, which may be incorporated as part of a bag, pouch, wrapper or liner, or which may be used as a protective garment closure, includes a pair of flexible closure strips and at least one zipper slider. The strips include interlocking ribs and channels of complementary cross-sectional shape which lock together in an interference fit. The ribs have enlarged heads, and, complementarily, the channels have enlarged bottoms. The strips also include webs to which sheet material or the like may be attached and, between the webs and the interlocking ribs and channels, an anti-derailing rib. The latter ensures that the zipper slider remains on track and does not derail from the interlocking ribs and channels when the slider is moved therealong to open or to close the zipper.
