Abstract: An air/water-tight slide fastener has an end stop. The end stop has a flange portion extending therearoud. At least part of the flange is extensive enough to be integrally fixed to the opening edges of an opening formed in an article. Since the flange portion is firmly clamped by and between the air/water-tight fastener tape and the opening edges of the opening of the article; when the air/water-tight slide fastener is folded on itself; the excessive bending stresses exerted directly on the air/water-tight fastener tape is relaxed or mitigated.

Abstract: A waterproof zip closure is formed by extruding a first thermoplastic material onto its teeth, and applying a transverse force while the first thermoplastic material cures. The transverse force is sufficient to move the teeth in the separating direction, but is less than that which can cause separation. After curing of the thermoplastic material, the tapes and teeth of the zip closure are coated with a second thermoplastic sealing material, while the transverse force is maintained. When the transverse force is removed the sealing material is forced together to provide a waterproof seal. The second thermoplastic sealing material on the tapes further improves the waterproof nature of the zip closure.
