When is pressed, the cylinder 10 slides downward in the drawing against the elastic force of the elastic body 9, and the valve portion 20 and the edge portion 20a of the second valve 13 form the flexible connecting portion 21. While extending, it separates from the valve seat portion 10b and opens the second valve 13 (see FIG. 5). Then, by the opening operation of the second valve 13, the liquid flows out from the inner hole 12 of the cylinder 10 into the liquid flow passage of the nozzle member 15, and the thin plate member 17 is deformed by the pressure of the liquid and the discharge port portion. The liquid flow passage is formed by expanding 17a, and eventually the liquid is discharged from the discharge port 18 formed in the nozzle body 16. When the discharge of the liquid is completed and the pressures of the liquid flow passage 15a and the inner hole 12 become equal, the thin plate member 17 returns to block the liquid flow passage again, and the second valve 13 is flexible.

The flexible connecting portion 21 is extended and separated from the valve seat portion 5b to open the first valve 7. The opening operation of the first valve 7 causes the liquid to flow out from the inner hole 8 of the piston 5 to the inner hole 12 of the cylinder 10 to prepare for the next use. And
After this preparatory action is completed, the inner hole 12 and the liquid chamber (liquid storage chamber)
When the pressure becomes equal to that of the second valve 7, the first valve 7 is closed by elastically contacting the valve portion 20 with the valve seat portion 5b due to the contracting action of the flexible connecting portion 21.

A piston having an inner hole communicating with the liquid chamber is provided at an opening of a container body having a liquid chamber inside, and a cylinder having an inner hole communicating with the discharge port is provided with respect to the piston. Liquid-tightly mounted so that it can be slid
A liquid passage communicating from the liquid chamber to the discharge port is formed. However, an openable and closable valve for communicating and blocking the liquid passage is provided in the liquid passage, and the piston and the cylinder are connected to each other. An elastic repellent body for urging the cylinder in a direction away from the piston is disposed between the two, and by pressing and releasing the pressing portion against the cylinder against the elastic force of the elastic repellent body, In a discharge container in which the cylinder is slid with respect to the piston, the valve is opened, and the liquid in the liquid chamber is discharged to a discharge port, the valve is a valve portion and a ring surrounding the valve portion. And a valve part and a ring part are connected by a connecting part made of a plurality of flexible materials.
