<P>PROBLEM TO BE SOLVED: To surely prevent a liquid from leaking during non-drinking time by making the liquid flow out from the inside only when suction is performed from the outside. <P>SOLUTION: A container is equipped with a container body 12 storing the liquid and having an opening on its upper part, a nozzle 14 having inside a flow path 14a which can be communicating with the inside of the container body 12 and provided above the container body 12, and a valve 18 for performing communication/non-communication between the flow path 14a and the inside of the container body 12. The valve 18 has a curved face part 18a which becomes convex toward the inside of the container body 12 during non-drinking time, and forms a slit 18b on its central part, and during non-drinking time, the slit 18b is closed and the inside of the container body 12 is not communicating with the flow path 14a of the nozzle 14. On the other hand, the curved face part 18a becomes convex to the nozzle 14 side by a suction force from the nozzle 14 side during drinking time, and the slit 18b is opened to make the inside of the container body 12 communicate with the flow path 14a of the nozzle. <P>COPYRIGHT: (C)2007,JPO&INPIT |
