1. Field of the Invention
The present invention relates to a female member of a snap fastener, in particular to a female member used by sewing it on clothes, such as blouse, with a thread.
2. Description of the Prior Art
A first preferred embodiment of the present invention is shown in FIGS. 1 to 4, in which
FIG. 1 is a plan view showing a female member of a snap fastener;
FIG. 2 is a sectional view showing said female member;
The present invention will be below described with reference to FIGS. 1 to 4 showing the first preferred embodiment thereof.
Referring now to FIGS. 1 to 4, reference numeral 1 designates a female member comprising a central ring-shaped portion 5 provided with a through hole 4 with which a projecting portion 3 of a male member 2 is engageable, four projecting pieces 6 - - - radially projecting outward from said central ring-shaped portion 5 and an outside ring-shaped portion 7 for connecting said projecting pieces 6 - - - to each other at a pointed end thereof integrally formed of synthetic resinous materials by the injection molding method so that the face and the back may be symmetrically formed. And, said projecting pieces 6 - - - are adapted to be sewed on a suit material of clothes at the pointed end side portion thereof, and said central ring-shaped portion 5 and each of said projecting pieces 6 - - - are provided with a radial slit 9 - - - communicating with said through hole 4. A thickness of said projecting pieces 6 - - - is slightly less than that of said outside ring-shaped portion 7, and each of said projecting pieces 6 - - - is provided with a reinforcing rib 6a- - - formed on both the face and the back at an end portion of a side of the outside ring-shaped portion 7. Reference numeral 10 designates a sewing space portion.
With the above described construction, since the female member 1 is formed of synthetic resins as a whole, it can be easily and inexpensively mass-produced by the injection molding method and the washing of clothes do not lead to the generation of rust.
