[Problems to be solved by the invention]
Although it is convenient to take out a small amount of liquid and apply it, there is a drawback that the total amount of liquid continuously taken out is unclear because the small amount is continuously taken out many times.

In the present invention, a required amount is measured in advance before the liquid is taken out, and the measured liquid can be applied by taking out the small amount.
