PROBLEM TO BE SOLVED: To provide a cap having a structure where fluid in a container is hardly accumulated inside a lid body.SOLUTION: An extraction cylinder 13 disposed on a cap body 4 has an extraction port 15 on a tip end part, and a flow port 19 communicating with the inside of a container 2 and the extraction port 15 is formed on a bottom in the extraction cylinder 13. A lid body 6 has a projection 32 for opening and closing the extraction port 15, and in a state where the lid body 6 is closed, the projection 32 is fitted to the extraction port 15, and an outer peripheral surface of the projection 32 contacts an inner peripheral surface of the extraction port 15. An inner surface 32a of the projection 32 facing the flow port 19 in the state where the lid body 6 is closed is a flat surface without a recessed part. |
