Abstract
The present invention is to provide an oxygen barrier cap with pull ring that maintains the opening easiness by tearing off with a pull ring, and the high productivity of one-piece molding by injection molding, and enhances significantly the gas barrier property, particularly oxygen barrier property. Further, in order to prevent conventional contamination of stored content caused by metal dust generated by tearing off the metal foil, or use of gas barrier resin molding material, the oxygen barrier cap with pull ring is molded from thermoplastic resin, and fixed to an opening of a container, and an oxygen barrier agent is coated on a score surface of a cap with pull ring, to form a coating film with oxygen barrier property.
