<p>A container cap with pull ring that while ensuring the easiness of tear opening by pull ring and the high productivity of one-piece molding by injection molding technique, realizes marked enhancement of gas barrier properties, especially oxygen barrier properties and simultaneously avoids any contamination of container contents by metal micropowder derived from conventional metal foil tearing, use of gas barrier resin molding materials, etc. There is provided an oxygen barrier cap with pull ring molded using a thermoplastic resin and to be fixed to a mouth part of container, characterized in that the cap with pull ring on its score surface is coated with an oxygen barrier agent to thereby form an oxygen barrier coating.</p> |
