Abstract

A snap button for attachment to a cloth is composed of male and female buttons engageable with each other. Each of the male and female buttons includes a face plate centrally from which a smashable shank projects, a snap body, and a resilient plate. The snap body has a respective one of concave socket and plug portions in which an axial shank-insertion hole, and a peripheral flange extending from a base portion of the plug and socket portions off an inner open end thereof. The resilient plate is adapted to be pierced by the shank so as to clamp the cloth between the face plate and the resilient plate. As a result, the cloth is held not only between the resilient plate and the shank but also between the shank and the snap body, and this clamp structure prevents the cloth from being removed off the each of the male and female buttons.

A snap button, for attachment to a cloth, which is composed of male and female buttons adapted to be coupled together, said male and female buttons comprising:

(a) a male face plate having a smashable shank projecting centrally from its inner surface for piercing a first part of the cloth;
(b) a male snap body having a concave plug portion, a shank-insertion hole extending axially through said plug portion, and a peripheral flange extending from a base portion of said plug portion off an inner open end thereof, wherein the male snap body is biased toward the male face plate and presses the first part of the cloth against the male face plate when the shank of the male face plate is deformed;
(c) a male resilient plate adapted to be pierced by and engaged with said shank of the male face plate so as to press the first part of the cloth against the inner surface of said male face plate;
(d) a female face plate having a smashable shank projecting centrally from its inner surface for piercing a second part of the cloth;
(e) a female snap body having a concave socket portion, a shank-insertion hole extending centrally through said socket portion, and a peripheral flange extending from a base portion of said socket portion off an inner open end thereof, wherein the female snap body is biased toward the female face plate and presses the second part of the cloth against the female face plate when the shank of the female face plate is deformed;
