Thereby, the coating liquid in the bottle 1 is supplied to the measuring chamber 2b of the fixed amount coating plug 2 through the pipe 3. At this time, the valve parts 2f and 2h of the valve cylinder 2e and the valve stem 2g are
Since 2e is closed, the air in the fixed amount application plug 2 is pressurized simultaneously with the supply of the application liquid. After supplying a predetermined amount or more of the coating liquid, when the squeezing of the body is released, since the internal pressure of the fixed amount coating plug 2 is initially higher than the internal pressure of the bottle 1, excess coating liquid is supplied to the bottle 1. After being pulled back, a predetermined amount of the coating liquid remains in the fixed amount coating plug 2, that is, in the measuring chamber 2b. Next, the whole is inverted, and the coating liquid in the measuring chamber 2b is transferred to the coating head 2c, and the valve rod 2g is brought into contact with a point to be coated, and the valve rod and the valve cylinder 2e are pushed in. Let it. Along with this,
First, the valve portion 2h of the valve stem opens the valve cylinder 2e, and the valve cylinder communicates the air in the measuring chamber 2b and the air in the bottle 1 with the outside air via the pipe 3 to form the fixed amount application plug 2 and The internal pressure of the bottle 1 is set to the atmospheric pressure. Subsequently, the valve portion 2f of the valve cylinder opens the spout 2d, and the coating liquid in the coating head 2c flows out from the spout.
This outflow can be performed continuously or every time the valve stem 2g and the valve cylinder 2e are pushed in, as long as the application liquid is present in the application head 2c. That is, a predetermined amount can be continuously or subdivided and discharged, and can be rubbed with the application head 2c. Needless to say, it is also possible to similarly use the coating liquid once received by the palm or the like. By the way, at the time of the above-mentioned coating etc., the inside of the bottle 1 is warmed by the palm, and the coating liquid and the air inside expand,
The internal pressure may increase. However, since the inside of the bottle 1 and the inside of the fixed amount application plug 2 are communicated with each other by the pipe 3, both are at equal pressures.
Moving through, there is no movement of the coating liquid.
