PROBLEM TO BE SOLVED: To minimize the number of components to reduce a manufacturing cost. SOLUTION: The lid includes a lid body 4 to be mounted on a container opening 102 and a lift member 6 to be mounted on the lid body 4 so that it can rise/lower. The lid body 4 is equipped with a plurality of portions 40 to be unsealed for opening passage via thin parts, while the lift member 6 is equipped with a plurality of pressing walls 48. The lift member 6 is mounted on the lid body 4 wherein it can rise/lower between an initial rising position and an unsealed lowered position. When the lift member 6 is lowered from the initial rising position to the unsealed lowered position, each of the pressing walls 48 functions to each of the portions to be unsealed for opening passage to have the thin parts broken for unsealing. |
