Document Type and Number:
Japanese Patent JPH09224718
Kind Code:
A
Abstract:

To eliminate a flaw and a problem in a conventional snap fastener.

In the female (recessed) side of the metal body of a snap fastener, an elastic engaging hole part 10, which expands through the elasticity of the material, is formed integrally with a flange part 11 around the hole part 10. In an opening side 12 of the hole part 10 in this metal body, an ornamental cap 13 is attached through the flange 11. In addition, on the bottom of the metal body, an engaging mouth 15 is provided to which a tack-on button 17 is attached to form the entire female side of the metal body. Then, a cylindrical cavity is formed downward in the center of the thin planar material and, in the center of a bottom 14 of that cavity, a hole is provided for the tack-on button 17; then, a notch is radially made from the outer circumferential edge of the flange 11 toward the cavity; using this notch, a part of the flange 11 is raised vertically, with the tip end of that raised piece curled inward to form a petal-shaped and freely expandable elastic engaging hole part 10.
