Embodiment

[0059] In the present invention, the front-rear direction of the metal double-sided meshing teeth refers to the orientation of the tape width direction when the metal double-sided meshing teeth are attached to the fastener tape, and the direction on the meshing head side is defined as the front direction. Let the direction of the zipper tape side be the rear direction. In addition, the left-right direction of the metal double-sided teeth refers to the direction of the front and back of the tape when the metal double-sided teeth are attached to the fastener tape, and the vertical direction of the metal double-sided teeth refers to the orientation of the tape when the metal double-sided teeth are attached to the fastener tape. The orientation of the tape length direction when the metal double-sided meshing teeth are respectively attached to the fastener tape.

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.

Description

technical field [0001] The invention of the present application relates to a metal double-sided meshing tooth in which an meshing convex portion and an meshing concave portion are respectively formed on both surfaces of a meshing head portion, and a slide fastener provided with the metal double-sided meshing tooth. Background technique [0002] Zippers are widely used for openings of bags and the like to open and close them. As such a slide fastener, a double slide fastener in which two sliders are arranged facing each other head to head or tail to tail, a single slide fastener in which one slider is arranged, etc. are known. [0003] In the double slide fastener, the slide fastener can be opened and closed regardless of which direction the two sliders are slid forward and backward along the meshing tooth row. In addition, in the single opening slide fastener, the slide fastener can be opened and closed by sliding the slider. [0004] There are slide fasteners using metal ...
