发明名称 Watertight slide fastener stringer.
摘要 <p>A watertight slide fastener stringer comprises a series of coupling elements (52) mounted on a watertight stringer tape (51) along a longitudinal edge portion thereof. Each coupling element includes a pair of upper and lower halves or members disposed one on each side of the stringer tape and joined by at least one integral connector extending through the stringer tape. Each of the coupling element members has a coupling portion (63) including a support portion (64) placed on a thickened sealing member (56) which is disposed on the longitudinal tape edge, a neck portion (65) on the support portion (64), and a coupling head (66) on the support portion (64) integral with the neck portion (65) and projecting from the thickened sealing member. The support portion (64) and the neck portion (65) jointly define therebetween a pair of recesses opening away from the plane of the stringer tape (51) for receiving therein the coupling heads (66) of mating coupling elements. A layer (68, 69)) made of a cured adhesive material is disposed on each side of the stringer tape (51) at least around the integral connector to prevent water leakage between opposite sides of the coupled fastener stringers.</p>
