ABSTRACT:
A container sealing member for a container used for preserving an aqueous liquid or semi-liquid material is disclosed. Said sealing member is characterized in that some of the space inside the sealing member is filled with an oxygen absorbent and the absorbent is separated from the contents of the container by a film which adheres to the sealing member so as to prevent the oxygen absorbent from contacting the contents of the container, the film having a plurality of fine openings and being gas-permeable but water-impermeable at one atmospheric pressure.
