And

[0005]

[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 2f of the valve cylinder 2e closes the outlet 2d, and the rod-shaped valve body 2h is seated and closed on the valve seat 2g. Is pressurized. When the body is squeezed after supplying a prescribed amount or more of coating liquid, the internal pressure of the fixed-volume coating stopper 2 is initially higher than the internal pressure of the bottle 1, so that excess coating liquid is transferred to the bottle 1. Then, a predetermined amount of coating liquid remains in the metering chamber 2b inside the quantitative coating stopper 2. 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 rod-shaped valve element 2h is brought into contact with the important point to be coated, and the rod-shaped valve element, and subsequently the valve cylinder. Push in 2e. Along with this, first, the rod-shaped valve body 2h opens to open the valve cylinder 2e, and the valve cylinder communicates the air in the measuring chamber 2b and the air in the bottle 1 via the pipe 3 to the outside air. The internal pressures of the constant volume coating stopper 2 and the bottle 1 are brought to atmospheric pressure, and subsequently the valve portion 2f of the valve cylinder opens the spout 2d, and the coating liquid in the coating head 2c spontaneously flows out from the spout. This outflow can be performed continuously or each time the rod-shaped valve body 2h and the valve cylinder 2e are pushed in, 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 possible to use the coating solution once received by the palm or the like. 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 by the fixed amount coating stopper 2, and then in the inverted posture, the rod-shaped valve body 2h and By pushing the valve cylinder 2e and opening the valve cylinder 2e and the spout 2d, the predetermined amount of the coating liquid can be continuously or subdivided outflow from the spout 2d, and at that time, Prior to pushing in the valve cylinder 2e that opens the spout 2d, push the rod-shaped valve body 2h to open the valve cylinder 2e, and open the valve cylinder 2e through the air in the metering plug 2 and the pipe 3 Since the air of the above is communicated with the outside air, the inner pressure of the constant volume coating stopper 2 and the bottle 1 can be made equal to the atmospheric pressure, and therefore, the internal pressure can always be made the atmospheric pressure at the time of pouring. Since the coating liquid once measured with the stopper 2 is allowed to flow out spontaneously, do not over- or under-apply. Not cheat it, by the by, or that we warmed up in the palm is the degree of compression, Desugi, nor cause a shortage out. 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. . Further, a valve seat 2g facing downward is formed at the tip of the valve cylinder 2e, and a short rod-shaped valve body 2h is seated and closed on the valve seat, and the tip of the rod-shaped valve body is pushed in from the valve cylinder tip to open the valve. Protrude as slightly as possible, connect one end of the elastic piece 2i to the rear end of the rod-shaped valve body 2h, attach a support ring 2j to the other end of the elastic piece, and place the support ring in the appropriate position in the valve cylinder 2e. Since the rod-shaped valve body 2h is biased in the seated and closed direction by the fitting and fixing and the elastic piece 2i, it is possible to store the rod-shaped valve body 2h related to ventilation in the valve cylinder 2e, and apply quantitatively. Since it does not project into the space inside the stopper to occupy the space, it is possible to eliminate useless space, and to make the size of the fixed quantity application stopper as small as possible, making it convenient to carry and use. Furthermore, since the periphery of the spout 2d is an elastic inward skirt portion 2q, the valve portion 2f of the valve cylinder 2e can be brought into close contact with the inner edge of the spout, and airtightness and watertightness can be ensured, and an accurate You can get the motion.
