| 摘要 |
The present invention relates to a slide fastener suitable for providing a water resistant closure between two edges of material. The fastener comprises first and second stringer tapes, each stringer tape having a multiplicity of coupling elements disposed in a row therealong and a slider captively engaged with the opposed rows of coupling elements of the first and second stringer tapes for reciprocal movement therealong and for bringing the coupling elements into and out of interlocking engagement. The slide fastener is provided with an elongate length of water resistant film, which extends longitudinally of at least one face of each of the first and second stringer tapes at least along a coupling element anchoring zone and across at least a root portion of coupling element receiving recesses defined by neighbouring coupling elements so as to provide web portions between neighbouring coupling elements whereby the web portions abut against and conform when the slide fastener is in a closed position, so as to provide a water resistant seal against the front faces of the coupling elements.
