ABSTRACT:
A button for being attached to a garment fabric has a button body composed of a double-walled tubular stem with an annular flange extending radially outwardly therefrom, a cap having an internal back place mounted on the annular flange, and a tack member having a central shank for penetrating the garment fabric and for extending into the tubular stem to join the tack member to the button body with the garment fabric interposed therebetween. The annular flange includes a first marginal wall flaring radially outwardly and having a plurality of radially outward projections. The cap also has a second marginal wall fitted over the first marginal wall and including a plurality of protuberances deformed radially outwardly by the projections, respectively. The projections and the protuberances are held in interlocking engagement for preventing the button body and the cap from rotating relatively to each other. The shank of the tack member has a tapered end portion which, upon being forced into the button body, is elastically deformable against the back plate laterally into the form of a retainer hook held in locking engagement with the tubular stem.
