Patent ID: 7850891

Claim:
A method of manufacturing a suction cup, the suction cup having a suction cup main body formed from an elastic synthetic resin material, an attachment surface formed on said suction cup main body, and a gel layer provided integrally with said attachment surface and formed of a gel, the surface of said gel layer serving as a suction surface, the method comprising: mating a primary mold with a common mold to form a suction main body molding cavity in the inside of said molds so that said attachment surface molded in a shape corresponding to said suction cup main body fronts on said primary mold; injecting said synthetic resin material in a fluid state into said suction cup main body molding cavity to mold said suction cup main body, opening said primary mold to obtain said suction cup main body on said common mold, with said attachment surface directed in the direction of separating said primary mold; then mating a secondary mold with said common mold to form a gel layer molding cavity having a shape corresponding to said gel layer in the inside of said molds and between said mold and said attachment surface; and injecting said gel in a fluid state into said gel layer molding cavity to mold said gel layer on said attachment surface, and opening said secondary mold to obtain said suction cup.
