The cap main body is constituted of an installation part to be installed on the mouth part of the container, a bulkhead for blocking an opening of the mouth part extended inward from the installation part, and a spouting cylinder stood around the spouting cylinder penetrating through the bulkhead. The upper lid is constituted of a top wall and a peripheral wall suspended at a peripheral edge of the top wall. On the back side of the top wall is suspended a sealing ring that seals an inner peripheral surface of the spouting cylinder of the cap main body.
