  • Metal double-sided tooth and slide fastener
    Patent number: 9101182
    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.

  • Button attaching fastener
    Patent number: 5940940
    Abstract: A button attaching fastener consisting of a button cap and an attachment plug. The button cap has centrally in its rear surface a socket, and the attachment plug has on one end a flange fitted in the socket with a clench portion provided along an outer periphery of the socket clenched over the flange through its substantially entire surface. The clench portion has on its outer surface a plurality of rotation-preventing projections extending radially outwardly from the base of the flange. The rotation-preventing projections serve to prevent the fastener from rotating on a piece of fabric, as of clothing, and also to increase the pulling strength of the attachment plug.
