[0001]

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 is blow-molded with a flexible material so as to be deformable, 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 spherically. Feeding to the body surface.

[0005] 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.

[0006]

For this reason, when the cap is mounted, the cap can be further pushed in with the inner cylinder of the cap sealing the tip of the chip, thereby reducing the volume of the sealed space in the inner cylinder. Then, the pressure in the inner cylinder increases. Therefore, the air in the inner cylinder enters the coating liquid tank,
Since the inside of the coating liquid tank is pressurized, there is no need to press the coating liquid tank with a fingertip during use.

However, since the spherical coated body is repelled by the spring, in order for air in the inner cylinder to enter the coating liquid tank, it is necessary to overcome the elasticity of the spring and retreat the spherical coated body. 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 tip, and the inner cylinder of the cap becomes longer,
There is a problem that it is difficult to perform pressure operation.

Therefore, according to the present invention, the air in the inner cylinder can be easily introduced into the coating liquid tank with the cap attached to pressurize the coating liquid tank, and the coating liquid tank is pressed with a fingertip during use. It is an object of the present invention to provide an applicator that does not need to be performed and has low manufacturing cost.

[0009]

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 contacts the inward leading edge of the chip, the tip holding the chip is connected to the coating liquid tank, and the coating liquid tank is filled with a highly viscous film-forming coating liquid and stirred. The tip of the cap is an applicator that seals the chip in a pressurized state with the outer periphery of the front end being in close contact with the inner peripheral surface of the inner cylinder of the cap. It is movably held at the leading end, and when the stirrer collides with the tail end of the chip during stirring of the coating liquid, the chip moves forward by the impact, the spherical coated body comes into contact with the inner bottom part of the inner cylinder of the cap and retreats, The pressurized air in the inner cylinder is separated from the inward tip edge of the So as to penetrate into the click.

[0010]

[Function] In other words, when the application liquid is stirred by shaking the application liquid tank with the cap attached, the chip is advanced by the impact of the stirrer, and the spherical application body comes into contact with the inner bottom of the inner cylinder of the cap. The applicator recedes and moves away from the inward leading edge of the chip, opening the valve mechanism. Therefore, the pressurized air in the inner cylinder easily enters the coating liquid tank and is pressurized.

When the stirring of the cap is completed, the tip is restored to the original position, and the spherical coating body comes into contact with the inward tip edge of the tip, and the valve mechanism is closed, so that the pressurized state is maintained. There is no need to press the liquid tank with a fingertip. Since the coating liquid tank does not need to be blow-molded with a flexible material and can be injection-molded with a normal hard synthetic resin, it can be manufactured at low cost.

[0012]

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.
The tip 3 is held at the front end opening of the front end 2 in which 1 is formed so as to be able to move back and forth. An impact receiving member 8 is connected to the rear end of the chip 3. The return spring 81 interposed between the impact receiving member 8 and the coating liquid tank 1 causes the tip 3 to rebound toward the tail end. . The tip 3 is formed in a shell shape from stainless steel, and a spherical coating body 4 made of a carbide ball having a diameter of 1.0 mmφ is partially exposed from the tip of the tip 3 in a ball house at the tip of the tip 3. It is held in a freely rotating state. 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, and the spring 5 resiliently presses the spherical coating body 4 against the inward leading edge 31 of the chip 3 to form a spherical coating. The body 4 and the leading edge 31 of the tip 3 constitute a valve mechanism. The leading end 2 is integrally connected to the coating liquid tank 1. The coating liquid tank 1 is injection-molded with a normal hard synthetic resin, and its manufacturing cost is lower than that obtained by blow-molding a flexible material. A coating liquid having a viscosity of, for example, 30 to 40 cps and having a high film forming property is filled with the coating liquid from the inside of the coating liquid tank 1 and the front end 2 to the chip 3. Is accommodated.

When the inner peripheral surface of the tip of
The inside of the inner cylinder 7 becomes a sealed space, and when the cap 6 is pushed in to complete the mounting, the volume of the sealed space in the inner cylinder 7 is reduced, so that the air in the inner cylinder 7 is pressurized.

When the cap 6 is attached to the front end 2, the air in the inner cylinder 7 is pressurized. In this state, when the application liquid tank 1 is shaken up and down to agitate the application liquid, as shown in FIG. Thus, the stirrer 9 collides with the tail end of the impact receiving member 8.
Therefore, the chip 3 advances due to the impact, and the spherical coating body 4 hits the pushing portion 71 at the inner bottom of the inner cylinder 7 and retreats. That is, since a gap is formed between the spherical coating body 4 and the tip end 31 of the chip 3, the pressurized air in the inner cylinder 7 enters the coating liquid tank 1, and the inside of the coating liquid tank 1 is pressurized. Is done.

When the stirring is completed, the tip 3 is restored to its original position by the elastic force of the return spring 81, and the spherical coating body 4 is separated from the pushing portion 71. Therefore, the spherical coating body 4 is again brought into contact with the tip 3
And the inside of the coating liquid tank 1 is maintained in a pressurized state.

As described above, when the coating liquid tank 1 is shaken and stirred with the cap 6 attached, the pressurized air in the inner cylinder 7 easily enters the coating liquid tank 1 and the coating liquid tank 1 is stirred. The inside is pressurized. Therefore, when the cap 6 is removed for coating, 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.

[0018]
