PROBLEM TO BE SOLVED: To keep liquid in a container in a sanitary condition, and to maintain the appearance shape of a container body, by retracting a valve member of the porous material with the pressure of the liquid, releasing a valve hole to discharge the liquid, and entering the air filtered by the valve member of the porous material though the air enters the container body. SOLUTION: The inside of a container body is a liquid chamber to store the liquid, a cylindrical mouth part 3 is projected on its upper part, and a cap 4 is screwed outside in an attachable/detachable manner. When a side of the container body is pressed, the pressure inside the liquid chamber is increased, the porous body 13 is retracted by the pressure, and a valve hole 7 is released to discharge the liquid from the valve hole 7. When the discharge is completed, the porous body 13 is elevated by an elastic member 16 to close the valve hole 7. When the pressing operation is released, the container body is restored, and the air enters from the valve hole 7 into the container. The air passes through the porous body 13 to reduce the number of germs, and filter and remove the dust. |
