PROBLEM TO BE SOLVED: To obtain a container plug with an oxygen absorbing function which can tightly seal a container mouth and can be opened in a similar way to a cork stopper, can reliably prevent oxidation and deterioration of contents, and can be manufactured in a relatively simple manufacturing method at a low cost. SOLUTION: The container plug is entirely formed to be cylindrical similar to a natural cork stopper, and comprises, from upward, a plug body 2, an adhesive layer 3, an oxygen barrier layer 4, an adhesive layer 5, a deoxidizing layer 6, an adhesive layer 7 and an oxygen permeable layer 8 which are laminated to integrate. The deoxidizing layer 6 has unevenness formed on a side facing the contents, thereby enlarging a surface area on the side facing the contents and improving oxygen absorbing efficiency. In addition, an oxygen barrier layer is provided either between the deoxidizing layer and the plug or on a top of the plug, thereby completely blocking entrance of oxygen from the outside. |
