To provide a container cap with a pull ring which retains easiness in tearing unsealing with the pull ring and high productivity achieved through one-piece molding using an injection molding method, improves a gas barrier property, especially greatly improves an oxygen barrier property, and prevents a decline in moldability and/or economic advantage and pollution of a stored object by metal powder resulting from tearing of a metal foil.

The oxygen barrier cap with the pull ring is made of a thermoplastic resin, and is fixed to a container mouth. A scored face of the cap with the pull ring is coated with an oxygen barrier agent to form an oxygen barrier film on the scored face.
