c Closes by pressing against the outer periphery, shuts off the communication between the spout 3a and the spout passage 2a, and prevents the contents from flowing out from the spout 3a of the cap 3. On the other hand, in use, when the pressure is depressed, the pressure in the ejection passage 2a increases, and when the pressure is accumulated to a magnitude corresponding to the elasticity of the valve portion 3b, as shown in FIG. It is deformed in the shape of a letter and detaches from the convex plug 2c to open the spout 3a.
Discharges the contents in the ejector body. When the push-down is released after use, the pressure in the ejection passage 2a is weakened, the elastic force of the valve portion 3b wins, and the communication between the ejection outlet 3a and the ejection passage 2a is interrupted. Prevent spill.

However, the conventional push button 1 has a configuration in which the convex plug 2c is inserted into the ejection port 3a, and the valve portion 3b is pressed against the outer periphery of the convex plug 2c to close the valve portion 3b. Therefore, for example, the frictional force between the valve portion 3b and the convex plug 2c is not uniform due to the combination of the ejection port 3a and the convex plug 2c. For this reason, there is a problem that the ejection state becomes unstable when the ejection port 3a is opened by separating from the convex plug 2c.

On the other hand, when the hand is released from the push button C to release the push, the push button C and the shaft-like member 17 are pushed up by the coil spring 30. At this time, the inclined portion 17c of the shaft-like member 17 is brought into contact with the lower end of the ejection pipe 16 so that the cylinder chamber 31 is moved.
The communication between the inside and the ejection pipe 16 is cut off, and the ejection pipe 16 is pushed up together. Then, when the pressure in the cylinder chamber 31 becomes negative, and the negative pressure overcomes the gravity of the valve member 15, the valve member 15 is opened and the contents in the plastic bag 13 are sucked into the cylinder chamber 31. Then, it returns to the original state shown in FIG.

As described above, according to the present invention, according to the present invention, when the valve is pressed down during use, the pressure in the ejection passage increases, and the pressing of the valve portion is released against the elastic force of the diaphragm portion. The outlet can be opened normally without distorting the outlet, and a stable discharge state can be obtained without dropping the contents.
