[Structure] A spherical applicator 4 is rotatably embraced with a part thereof protruding from the tip of the tip 3, and the spherical applicator 4 is elastically springed by a spring 5 to inwardly tip the tip 3. The tip 2 that contacts the edge 31 and holds the chip 3 is connected to the coating liquid tank 1 that is made of metal with excellent thermal conductivity and also functions as a barrel, and the coating liquid tank 1 is coated with a highly viscous film-forming agent.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an applicator filled with a highly viscous coating liquid such as a correction liquid or a cosmetic liquid.

[0002]

[Prior art]

 The applicator, which has a spherical applicator, has a tip attached to the tip of a coating liquid tank filled with the coating liquid through the tip, and like a ball-point pen, a part of the tip is exposed from the tip. The spherical applicator is rotatably held in the extended state. Then, the spherical applicator is repelled by a spring, and when not in use, the spherical applicator is brought into close contact with the inward tip edge of the chip, and the spherical applicator and the tip end edge of the chip form a valve structure so that the coating liquid does not discharge. I am trying.

When the spherical applicator is pressed against the application surface during use, the spherical applicator retreats against the elastic force of the spring and a gap is created between the spherical applicator and the tip edge of the chip. The coating liquid adhering to the inside of the tip of the spherical applicator passes through this gap and is applied to the outside of the chip as the spherical applicator rotates.However, since the viscosity of the coating liquid is high, it is applied in a natural state. The liquid is not sufficiently supplied to the surface of the spherical coated body. For this reason, the coating liquid tank can be blow-molded with a flexible material to make it deformable, and when in use, the coating liquid tank is pressed with a fingertip to pressurize the inside, and the pressure is used to apply the coating liquid to the surface of the spherical coating. Is being supplied to.

[0004]

[Problems to be solved by the device]

 As described above, since it is necessary to press the coating liquid tank with a fingertip to pressurize the inside during use, the operation is complicated, and the manufacturing cost is high because the coating liquid tank is blow-molded with a flexible material. There is a defect.

Therefore, when the cap is mounted, the cap can be further pushed in a state where the tip of the tip is sealed by the inner tube of the cap, and the volume of the sealed space in the inner tube is reduced. The pressure will increase. Therefore, the air in the inner cylinder invades the coating solution tank and pressurizes the coating solution tank, so that it is not necessary to press the coating solution tank with a fingertip during use.

However, since the spherical applicator is elastically ejected by the spring, in order to allow the air in the inner cylinder to enter the coating solution tank, it is necessary to overcome the elastic force of the spring and retract the spherical applicator. There is. Therefore, it is necessary to sufficiently increase the pressure in the inner cylinder. In other words, it is necessary to increase the pushing distance of the cap when the inner cylinder seals the tip of the chip, which makes the inner cylinder of the cap longer and makes it difficult to perform the pressing operation.

Therefore, an object of the present invention is to provide an applicator that can pressurize the inside of the coating liquid tank with a simple structure and does not need to press the coating liquid tank with a fingertip during use. .

[0008]

[Means for Solving the Problems]

 The purpose of this is that the spherical applicator is rotatably embraced with part of it protruding from the tip of the chip, and the spherical applicator is spring-loaded by the spring to contact the inward tip edge of the chip. Achieved by an applicator in which the tip that holds the chip is made of metal with excellent thermal conductivity and is connected to a coating liquid tank that also functions as a barrel, and the coating liquid tank is filled with a film-forming coating liquid with high viscosity. To be done.

[0009]

[Action]

 In other words, since the coating liquid tank that also functions as the barrel is filled with the highly viscous film-forming coating liquid and is made of metal with excellent thermal conductivity, when applying the liquid by holding the coating liquid tank, As a result, the inside of the coating liquid tank is heated and pressurized. Therefore, it is not necessary to pressurize the inside of the coating liquid tank by pressing the coating liquid tank with a fingertip during use, and the coating can be easily applied.

【Example】

 The present invention will be described in detail below with reference to the embodiments shown in the drawings. In FIG. 1, a tip 3 is fitted in the tip opening of the front opening 2. The tip 3 is formed of stainless steel in a bullet shape, and the ball house 32 at the tip of the tip 3 has a spherical coating body 4 made of a superhard ball having a diameter of 1.0 mmφ, a part of which is from the tip of the tip 3. It is embraced in a freely rotatable state in an exposed state. The tip 3 may be made of a metal pipe.

A small spring 5 having a spring force of 40 g is arranged in the tip 3, and the spring 5 repels the spherical applicator 4 and presses it against the inward tip edge 31 of the tip 3 to form a spherical shape. The applicator 4 and the tip edge 31 of the tip 3 form a valve mechanism. The front port 2 is integrally connected to the coating liquid tank 1. The coating liquid tank 1 doubles as a shaft cylinder, but is made of a metal having excellent thermal conductivity, such as an aluminum pipe, and a tail plug 6 is attached to its tail end. Then, from the inside of the coating liquid tank 1 and the front port 2 to the chip 3, the coating liquid, which is a repairing liquid having a viscosity of 30 to 40 cps and having a high film-forming property, is filled. In addition, a rod-shaped or spherical stirrer (not shown) is arranged in the coating liquid tank 1, and by shaking the coating liquid tank 1 before use, the coating liquid is agitated to remove the pigment and the solvent. Mix evenly.

Then, the coating liquid tank 1 is held by hand, and the coating liquid is filled with the film-forming coating liquid having high viscosity, and the coating liquid tank 1 also serving as the barrel is formed of metal having excellent thermal conductivity. Therefore, the temperature of the inside of the coating liquid tank 1 is raised by the body temperature of the hand to be pressurized, and the coating liquid is sufficiently supplied to the spherical coating body 4. Therefore, it is not necessary to pressurize the inside of the coating liquid tank by pressing the coating liquid tank with a fingertip at the time of use, and the coating can be easily performed by writing with a ballpoint pen.

[0013]

[Effect of device]

 As described above, in the applicator of the present invention, the spherical applicator is rotatably held while a part of the applicator is exposed from the tip end of the tip, and the spherical applicator is elastically repelled by the spring. The tip of the tip that contacts the inward tip edge of the tip is made of metal with excellent thermal conductivity and is connected to the coating liquid tank that also functions as a shaft cylinder. Since the coating solution is filled, the inside of the coating solution tank can be pressurized with a simple structure, and it is possible to provide an applicator that does not require pressing of the coating solution tank with a fingertip during use.
