Snap fastener and snap strap fastener for clothing

Abstract

An easy to engage and disengage snap fastener for clothing, made of a semi rigid plastic material but also of a more flexible vinyl or rubber like material or a combination of both materials, and an easy to engage and disengage snap strap fastener made preferably of a semi rigid plastic material but also of a more flexible vinyl or rubber like material or a combination of both materials and a strip of thermoplastic yarn web or fabric, said snap strap fastener could be adjustable in some applications. The male fastener part is substantially spherical in shape and the female fastener part, of thin walled construction, is substantially oval or elliptic in its base portion and substantially circular in its upper portion, also engaging portion. The inner diameter of the upper circular portion of the female part fastener is slightly smaller than the outer diameter of the male fastener part, said upper portion of the female fastener part flexes open, upon downward pressure being applied to the male fastener part against the female fastener part, thus allowing the male fastener part to engage and fasten in place.
