  • Patent number: 5745964
    Abstract: A push-button closure part including a contoured button, a metallic rivet part having a rivet shank projecting from the underside of the button and an approximately radially extending, round rivet flange. The closure part includes a push button eyelet for slipping onto the rivet shank through a central opening. The rivet shank is deformed in a shallow S-shape which causes flexible material clasped between the rivet flange and the eyelet to be pressed between the edge of the central opening of the eyelet and rivet flange and also between the surrounding outer edge of the eyelet and the rivet flange.
