<P>PROBLEM TO BE SOLVED: To provide a cap wherein a content liquid is not adhering to the surfaces of a lid body and a cap body when the lid body is opened when being used, and which has a clean image. <P>SOLUTION: A pouring port 11 is provided in a protruding part 10 which is formed on the top surface part 9 of the cap body 1 which is fitted on the mouth 4 of a container, and a valve chamber 13 is formed in the pouring port 11. At the same time, a spherical valve 14 which can vertically move is arranged in the valve chamber 13. Therefore, even when the content liquid remains in the upper space of the pouring port 11 after pouring out the content liquid, a part of the remaining content liquid adheres to the upper surface of the spherical valve 14, and the spherical valve 14 descends to a valve seat 16b in the pouring port 11 by the self-weight and the suction by the restoring force of the container. Therefore, the content liquid does not remain in the upper space of the pouring port 11, and in addition, the content liquid does not adhere to a closing part 22 of the lid body 3 as well. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
