Abstract: Provided are a metal double-sided tooth that prevents a flow protruding portion from protruding from the boundary between a coupling concave portion and a body, and a slide fastener using the metal double-sided tooth. The inner side of a coupling concave portion is formed in a substantially bowl shape and a concave portion is formed throughout the boundary between the coupling concave portion and a body and a front side and a rear side of the body. Further, when the metal double-sided tooth is attached to a fastener tape, it is possible to prevent a flow protruding portion generated by caulking a pair of legs from protruding outward from the coupling concave portion or the front side and the rear side of the body until sliding friction is generated in a slider.

Abstract: Metallic one-side teeth that attain preventing of colliding contact at interlock, enhancing of rigidity against moment by horizontal pull force and construction of simple structure; and a two-way slide fastener utilizing the metallic one-side teeth. An upper inclined plane (8) declining toward the side of interlock dent portion (5) is provided between the opening edge (5a) of the interlock dent portion (5) and the apical edge (7) of an interlock head portion (3). By virtue of the upper inclined plane (8), at insertion in the interlock dent portion (5), there can be prevented any insertion of an interlock convex portion (4) as an interlock counterpart-side while making colliding contact with the interlock head portion (3). Accordingly, the sliding movement of slider for opening/closing of a two-way slide fastener can be smoothed.

With the provision of the guide groove, the coupling elements are mutually engageable and disengageable with least friction resistance when the slide fastener is opened and closed in either of two reciprocal directions. A simple method of making such coupling element is also disclosed.

Abstract: A coupling element of a slide fastener stringer has a pair of integral upper and lower coupling portions having different shapes and engagable with the lower and upper coupling portions of adjacent coupling elements on a co-operating like stringer. The upper coupling portion has a side surface including a flat abutment surface extending perpendicularly to a stringer tape across the thickness of a longitudinal edge portion of the stringer tape. When lateral pulling forces are applied to the coupled stringers, areas on the abutment surfaces of the interdigitating coupling elements take up such forces and prevent the stringers from separation.
