BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an applicator filled with a highly viscous application liquid such as a correction liquid or a cosmetic liquid.

[0002]

2. Description of the Related Art An applicator having a spherical applicator has a tip attached to a tip of a coating liquid tank filled with a coating liquid through a tip, and like a ballpoint pen, a tip is partially attached to the tip. The spherical application body is held rotatably in a state where it comes out from the tip. Then, the spherical application body is repelled by a spring, and when not in use, the spherical application body is brought into close contact with the inward tip edge of the chip, and a valve structure is formed by the spherical application body and the tip edge of the chip so that the application liquid is not discharged. Like that.

[0003] In use, when the spherical coated body is pressed against the coated surface, the spherical coated body retreats against the resilience of the spring, and a gap is formed between the spherical coated body and the tip edge of the chip. The coating liquid adhering to the inside of the chip of the coating body is applied to the outside of the chip through this gap with the rotation of the spherical coating body and is applied, but since the viscosity of the coating liquid is high, the coating liquid is in a natural state. Is not sufficiently supplied to the surface of the spherical coated body. For this reason, the coating liquid tank can be deformed by blow molding with a flexible material, and when used, 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 coated body. To supply.

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

[0005]

By the way, if the coating liquid tank is formed of a metal having good thermal conductivity, the body temperature of the hand is transferred to the coating liquid tank when the coating liquid tank is gripped at the time of coating. The temperature inside becomes high. Therefore, the air in the coating liquid tank expands and is pressurized, so that it is not necessary to press the coating liquid tank with a fingertip during use. However, the body temperature of the palm that is not in direct contact with the coating liquid tank as well as the fingertip that contacts the coating liquid tank is also transmitted to the coating liquid tank, so the inside of the coating liquid tank becomes too hot, that is, the pressure becomes too high and The liquid may be discharged excessively.

Accordingly, an object of the present invention is to provide an applicator which does not need to press the application liquid tank with a fingertip during use and does not excessively discharge the application liquid.

[0007]

In order to achieve the above object, the present invention provides a spherical coating body in which a spherical coating body is rotatably held with a part thereof protruding from the tip of a chip. Is repelled by a spring and comes in contact with the inward tip edge of the chip, and the coating liquid tank in which the chip is connected to the tip is filled with a highly viscous film-forming coating liquid. Although the surface of the metal bottomed cylinder is covered with a heat insulating material, the portion where the fingertip abuts when the application liquid tank is gripped at the time of application is removed so that the metal surface is exposed.

[0008]

[Function] That is, since the metal surface is exposed at the portion where the fingertip comes into contact when the application liquid tank is gripped during application,
The body temperature of the fingertip is transmitted to the application liquid tank and the inside is pressurized,
It is not necessary to press the application liquid tank with a fingertip, but the body temperature of the palm is not conducted to the application liquid tank because the other parts are covered with heat insulating material. For this reason, the inside of the coating liquid tank is not excessively pressurized, and it is possible to prevent the coating liquid from being excessively discharged.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to the embodiments shown in the drawings. In FIG. 1, a chip 3 is connected to a tip of a coating liquid tank 1 via a front port 2. Chip 3
Is made of stainless steel in a shell shape, and the tip 3
A spherical coated body 4 made of a carbide ball having a diameter of 1.0 mmφ is rotatably held in the ball house at the tip with a part thereof protruding from the tip of the chip 3. Note that the chip 3 may be made of a metal pipe. A small spring 5 having a spring force of 40 g is arranged in the chip 3. The spring 5 rebounds the spherical coating body 4 and presses the spherical coating body 4 against the inward leading edge 31 of the chip 3. The tip edge 31 of the tip 3 constitutes a valve mechanism.

The coating liquid tank 1 is a bottomed metal cylinder 11 having a high thermal conductivity such as an aluminum alloy. The surface of the bottomed metal cylinder 11 is formed of, for example, a synthetic resin having a low thermal conductivity. Covered with a sheet-like heat insulating material 12. However, when the application liquid tank is gripped at the time of application, the fingertip contact portion 13 where the fingertips of the thumb, index finger, and middle finger abut is insulated by the heat insulating material 12.
Has been removed to expose the metal surface. A coating liquid (not shown), which is a correction liquid having a viscosity of, for example, 30 to 40 cps and having a high film forming property, is filled from the inside of the coating liquid tank 1 and the front opening 2 to the chip 3. Is provided with a stirrer (not shown).

Thus, when the application liquid tank is gripped during application, the thumb, index finger and middle finger of the fingertip contact portion 13
Since the heat insulating material 12 is removed and the metal surface is exposed, the body temperature of the fingertip is transmitted to the application liquid tank 1 and the air inside the fingertip contact portion 13 expands. Therefore, the inside of the coating liquid tank 1 is pressurized, and the coating liquid is sufficiently supplied to the spherical coating body 4. In other words, there is no need to press the coating liquid tank 1 with a fingertip, and the coating can be reliably applied in the manner of writing with a ballpoint pen. However, since the metal bottomed cylinder 11 is covered with the heat insulating material 12 except for the fingertip contact portion 13, the body temperature of the palm is hardly conducted to the application liquid tank 1. Therefore, the inside of the coating liquid tank 1 does not become too high, that is, is not excessively pressurized, and the coating liquid is not discharged excessively.

[0012]

[Effects of the Invention] As described above, in the applicator of the present invention, the coating liquid tank is formed by covering the surface of the metal bottomed cylindrical body with the heat insulating material. The parts where the fingertips abut are exposed to the metal surface by removing the heat insulating material, so there is no need to press the coating liquid tank with the fingertips during use, and a coating tool that does not excessively discharge the coating liquid. can do.
