[Problems to be solved by the invention] However, when a certain amount of pouring cannot be obtained, and when the internal pressure fluctuates depending on the degree of squeezing or being warmed by the palm, sometimes the overshoot and sometimes the shortage occur. Occurs. The present invention is intended to solve the conventional drawbacks, and at the same time, is intended to simplify a fixed amount application plug and obtain an easy operation and a reliable operation.

[0004]

According to the present invention, a fixed amount application plug 2 is fitted to a mouth and neck portion 1a of a squeeze type bottle 1, and the fixed amount application plug has a measuring chamber 2b inside thereof. A plug body 2a is fitted to the neck 1a in an airtight manner, and a pipe 3 is suspended from the plug body into the bottle 1 to allow the pipe to communicate with the measuring chamber 2b and to be applied to the plug body 2a. A head 2c is provided, and a short and small cylinder portion 2d is formed on the tip of the application head with a diameter slightly smaller than other portions, and a spout 2f is formed in the center of the top wall 2e, and the inner edge of the spout is formed. A valve body 2h is movably provided in the coating cylinder, and the valve body 2g is detachably seated on the valve seat 2g and the valve body 2h is inserted into and out of the cylinder part 2d. A piston portion 2j freely inserted, a projection 2k projecting upward from the center of the valve body and inserted through the spout 2f so as to allow air to flow therethrough, and the piston portion 2j upward. To thereby open it provided a ventilation tube 2l suitable length and vertically from position further characterized in that is biased in the closing direction and take the valve body urging means.

[0005]

[Effects] The configuration is as described above.
The body 1b of the bottle 1 containing the coating liquid is squeezed in the upright posture. 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 portion 2i of the valve body 2h closes the spout 2f, and the piston portion 2j of the valve body 2h enters the cylinder portion 2d deeply and the spout 2f.
Is closed, so that 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 coated with the coating head 2c.
And the protrusion 2k of the valve element 2h is brought into contact with a point to be coated, and the protrusion is pushed in. Accordingly, first, the valve portion 2i of the valve body 2h is opened to open the spout 2f, and the air in the measuring chamber 2b is further passed through the ventilation tube 21 and the air in the bottle 1 is passed through the pipe 3. Communicates with the outside air, and the internal pressure of the fixed amount application plug 2 and the bottle 1 becomes the atmospheric pressure. Then, when the protruding member 2k is pushed further deeply, the piston portion 2j of the valve body comes out of the cylinder portion 2d and is spouted. The flow path to 2f is opened, and the coating liquid in the coating head 2c naturally flows out from the spout. This outflow can be performed continuously or every time the protrusion 2k is pushed in as long as the coating liquid is present in the coating 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.
