瞬時に吐出してしまうという欠点があつた。(Prior art) In conventional applicators of this kind, by pressing the applicator body or the main body, a valve pressed against the opening at the tip of the coating liquid chamber is opened and the coating liquid flows out into the applicator body. In the case of a coating liquid using a low-boiling point solvent, the entire coating liquid chamber is pressurized, and a large amount of the coating liquid is instantly discharged.

ある。(Structure) In order to achieve the above object, the present invention communicates with the opening at the tip of the main coating liquid chamber to form a small chamber, and in this small chamber, an intermediate valve and a tip valve are arranged, and each is connected to the tip of the main coating liquid chamber by a spring. It is characterized in that it is in pressure contact with the opening and the tip opening of the small chamber, and an applicator is fixed to the tip valve.

の栓、１１はキヤツプである。 An embodiment of the present invention shown in the accompanying drawings will be described in detail below. Reference numeral 1 denotes a main body, which has a small chamber 3 in communication with a main coating liquid chamber 2 and its tip opening 2a, and a stirring member 4 made of an appropriate material and having an appropriate shape is accommodated in the main coating liquid chamber 2. Reference numeral 5 designates an intermediate valve which is brought into contact with a valve seat 2b at the tip of the opening 2a by means of an elastic member 6 such as a spring, and has a protrusion 5a formed at its rear end. Reference numeral 7 designates a tip valve having a coating body 8 made of a bundle of synthetic fibers fixed to its tip, which is pressed against the valve seat 3b of the tip opening 3a by an elastic member 9 such as a spring installed between it and the intermediate valve 5. There is. 10 is a plug at the rear end, and 11 is a cap.

吐出する。 Next, the effect will be explained. When in use, when the applicator 8 is placed downward and the entire body is shaken up and down, the stirring member 4 moves up and down within the main application liquid chamber 2 and comes into contact with the protrusion 5a of the intermediate valve 5, and each time it bounces the intermediate valve 5. It opens against the elasticity of the member 6, and the coating liquid in the main coating liquid chamber 2 flows out into the small chamber 3. Then, when the application body 8 is pressed against the application surface, the tip valve 7 resists the elasticity of the elastic member 9 and the valve seat 3b
The coating liquid in the small chamber 3 is discharged onto the coating body 8.

The rear end of 5 is a spherical portion 15a. In this embodiment, since the spherical portion 15a is retracted from the rear end surface of the opening 2a, it is necessary to provide a protrusion at the tip of the stirring member.
Note that the ball portion 15a can also be formed separately from the intermediate valve body 15.

でき、円滑に塗布することができる。(Effects) According to the present invention, a small chamber is formed in communication with the tip opening of the main coating liquid chamber, and an intermediate valve and a tip valve are arranged in this small chamber, and springs are used to connect the tip opening of the main coating liquid chamber and the tip of the small chamber, respectively. Since the applicator is in pressure contact with the opening and the applicator is fixed to the tip valve, the main coating liquid chamber is blocked by the intermediate valve during coating, so even if a coating liquid using a low boiling point solvent is used, the main coating liquid will not be able to be applied. Since the pressure of the gas evaporated in the liquid chamber is not transmitted to the small chamber 3, even if the tip valve is opened, the coating liquid in the small chamber can be reliably prevented from being instantly discharged, and coating can be performed smoothly.
