[Action]

 With the above configuration, in use, first, the body portion 1b of the bottle 1 containing the coating liquid is squeezed in an upright posture. As a result, the coating liquid in the bottle 1 is supplied to the measuring chamber 2b of the fixed amount coating stopper 2 through the pipe 3. At this time, the valve portion 2i of the valve body 2h closes the outlet port 2f, and the piston portion 2j of the valve body 2h deeply enters the cylinder portion 2d to close the flow path to the outlet port 2f. Simultaneously with the supply of the liquid, the air in the fixed amount coating stopper 2 is pressurized. When the body is squeezed after supplying a predetermined amount or more of coating liquid, the internal pressure of the fixed amount coating stopper 2 is initially higher than the internal pressure of the bottle 1, so that the excess coating liquid is transferred to the bottle 1. A predetermined amount of the coating liquid remains in the fixed amount coating stopper 2, that is, in the measuring chamber 2b. Next, the whole is inverted, the coating liquid in the measuring chamber 2b is transferred to the coating head 2c, and at the same time, the protrusion 2k of the valve body 2h is brought into contact with a point to be coated and the protrusion is pushed. Let Along with this, first, the valve portion 2i of the valve body 2h opens and the spout 2f opens, and the air in the measuring chamber 2b passes through the through cylinder 2l, and the air in the bottle 1 further passes through the pipe 3. Is communicated with the outside air, the internal pressure of the constant-volume coating stopper 2 and the bottle 1 becomes atmospheric pressure, and the protrusion 2k of the valve is pushed further deeply, so that the piston portion 2j of the valve element comes out from the cylinder portion 2d and is poured. The flow path to the outlet 2f is opened, and the coating liquid in the coating head 2c spontaneously flows out from the pouring outlet. This outflow can be performed continuously or each time the protrusion 2k is pushed, as long as the coating liquid is present in the coating head 2c. That is, the predetermined amount can be continuously or subdivided and discharged, and this can be rubbed with the application head 2c. Of course, in the same manner, it is also possible to once receive the coating liquid on the palm or the like and use it. By the way, at the time of the above-mentioned coating, the inside of the bottle 1 may be warmed by the palm, the coating liquid and the air therein may expand, and the internal pressure may rise. However, since the inside of the bottle 1 and the inside of the fixed amount application stopper 2 are connected by the pipe 3, both are at equal pressure, and in the inverted position, only air moves through the pipe 3 and the application liquid does not move. Absent.

[Effect of the device]

 According to the present invention, by squeezing and releasing the bottle 1 in the upright posture, it is possible to accurately measure the amount of the coating liquid to a predetermined amount with the fixed amount coating stopper 2, and then in the inverted posture, push in the protrusion 2k. As a result, the predetermined amount of the coating liquid can be continuously or subdivided out from the spout 2f, and at that time, the valve body piston portion 2j can open the flow path to the spout 2f. Prior to this, only the spout 2f was opened, and the air in the fixed quantity coating stopper 2 and the air in the bottle 1 were communicated to the outside air via the pipe 3, so the internal pressure of the fixed quantity coating stopper 2 and the bottle 1 was brought to atmospheric pressure. As a result, the internal pressure can always be made atmospheric pressure at the time of pouring, and at the time of pouring, the coating liquid once measured by the fixed amount coating stopper 2 is naturally discharged, so that over- and under-supply can occur. Not depending on the degree of squeezing or warming with the palm By being given, there will be no excessive or insufficient output. Further, in the inverted posture, even if the inside of the bottle 1 is warmed by the palm and the coating liquid and the air inside expand, and the internal pressure rises, the inside of the bottle 1 and the inside of the fixed amount coating stopper 2 become equal pressure by the pipe 3. Moreover, since only the air moves through the pipe 3 and the coating liquid does not move, the amount of the coating liquid measured overnight does not fluctuate, and it is possible to always obtain an accurate fixed amount of coating. . Furthermore, since the valve member installed inside the metered-dose tap 2 is one valve body 2h, the structure can be simplified, and the pushing operation can be performed only by pushing one protrusion 2k, which is extremely easy. , The operation can be ensured. Moreover, in the inverted position, the coating liquid is double-closed by the valve portion 2i and the piston portion 2j of the valve body, so that the liquid leakage can be reliably prevented.
