Claims24
A button for attachment to a garment fabric, comprising:
- (a) a capped button body including a hollow hub having a flanged free end;
- (b) a tack member having a head and a shank projecting perpendicularly and centrally from said head for being forced through the garment fabric into said hollow hub of said button body to thereby join said tack member with said button body, said shank including
- (1) a cylindrical stem contiguous to said head,
- (2) an end portion extending coaxially from said stem, and
- (3) a cold-pressed recessed portion disposed circumferentially in said stem adjacent to said end portion and having a stiffness greater than the other portion of said shank, said recessed portion being disposed in such a position that the same is disposed adjacent to said flanged free end of said hollow hub when said shank is fully inserted through said hollow hub with the garment fabric sandwiched between said hollow hub and said head of said tack member, said end portion being plastically deformable about said recessed portion into an axially compressed and radially uniformly swelled configuration when said shank is forced into said button body.
