Title:
METAL DOUBLE-SIDED TOOTH AND SLIDE FASTENER
Document Type and Number:
WIPO Patent Application WO/2011/135699
Kind Code:
A1
Abstract:
Provided is a metal double-sided tooth configured in such a manner that a fluid protrusion does not get pushed out from the boundary surface between an interlock recess and a body. Also provided is a slide fastener that uses the metal double-sided tooth. The shape of the inner peripheral surface of the interlock recess (5) exhibits a roughly conical shape, and straddles the boundary surface (9) of the interlock recess (5) and the body (6), together with the surface (6a) and undersurface (6b) of the body (6) to form a recessed portion (10). When the metal double-sided tooth (1) is attached to fastener tape, the fluid protrusion produced by crimping a pair of legs (2) can be prevented from getting pushed outside from the surface and undersurface of the body or the side of the interlock recess, until sliding friction has been generated in the slider.
