PURPOSE:To remove residual oxygen fast out of a container and to prevent deterioration of quality and decline of flavor from occurring to substance enclosed in the container by a method wherein minutely rugged face is formed on the surface of an oxygen-absorbing resin composition provided either on a resin liner or a packing so that the rugged face covers almost entirely the surface on its central part facing the inside of the container. CONSTITUTION:A container cap 1 is type of crown cap and is made up of a container cap shell body 2 and a sealing liner 3 that is provided on the inside of the shell body 2, which is formed of a top board part 4 and its circumferential skirt part 5 that are made up by integrally forming metal or the like. The sealing liner 3 is provided on a part that is provided on the inside of the shell body 2 for engagement with a mouth of the container, and the liner is made of oxygen absorbing resin composition, in which deoxygenation agent is mixed for dissipation of the oxygen. The liner 3 is equipped with a central part 7 that is smaller than a surrounding sealing part 6 for engagement with the mouth of the container, and is exposed to the inside of the container. Minutely rugged face 8 is formed over the surface of the central part 7. |
