DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to an applicator filled with a highly viscous film-forming coating liquid such as a correction liquid or a nail polish.

[0002]

2. Description of the Related Art A ball-point pen type applicator having a spherical coating body has a tip similar to a ball-point pen attached to the tip of a coating liquid tank filled with a coating liquid through a front end, and the tip of the tip is inserted from the tip of the tip. The spherical application body is held rotatably with a part thereof protruding. 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. At the time of use, the coating liquid tank is pressurized to supply a high-viscosity coating liquid to the spherical coating body, and the spherical coating is applied by a ballpoint pen. Such a ballpoint pen-type applicator has the advantage that, in the case of a correction tool, small characters can be finely corrected. Also, recently, nail polish is filled, and a small pattern or the like is drawn on the surface of the nail with the nail polish.

[0003] In a brush-coating type applicator, a lid is detachably screwed onto a bottle filled with nail polish, as typified by a nail polish, and a fibrous body is bundled behind the lid. In many cases, an application rod having a brush-shaped application body formed at the tip is attached thereto, and a lid is removed at the time of use. A correction tool filled with a correction liquid has also been put to practical use. Such a brush-coated type applicator,
It has the advantage that a wide range can be applied efficiently.

[0004]

As described above, the ball-point pen type applicator can apply a small area finely, but cannot apply a wide area efficiently. The applicator can apply a wide range efficiently, but cannot apply a narrow range finely. However, in an actual application operation, it is sometimes necessary to apply a narrow area finely and to apply the wide area efficiently. In such a case, it is necessary to prepare two types of application tools.

Therefore, the present invention has a simple structure,
An object of the present invention is to provide an applicator capable of applying a narrow range finely by kind and applying a wide range efficiently.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a spherical coating body, wherein 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 into contact with the inward leading edge of the chip, and the tip holding the chip is detachably screwed into the tip opening of the coating liquid tank filled with a highly viscous film-forming coating liquid. Then, the brush-like application body that bundled the fibrous body fixed the application rod formed at the tip to the tip end in the opposite direction to the chip,
When the front end is screwed into the coating liquid tank, the brush-shaped coating body is immersed in the coating liquid.

[0007]

Embodiments of the present invention will be specifically described below with reference to the drawings. In FIG. 1, a coating liquid tank 1 is blow-molded with a plastic resin, and is a substantially bottomed cylindrical body that can be deformed when pressed with a fingertip. An external thread 11 is integrally formed at the tip of the coating liquid tank 1. A seat 12 is attached to the bottom of the coating liquid tank 1 so that the seat 12 is stable when placed upward on a desk. In the coating liquid tank 1, a coating liquid L having a high viscosity, such as a correction liquid or a nail polish liquid, is placed.
Is filled.

An inner thread 21 is formed at the tail end of the front end 2, and the inner thread 21 is detachably screwed to the outer thread 11 of the coating liquid tank 1. A tip 3 of a ballpoint pen type and a coating rod 5 having a brush-shaped coating body 6 formed by bundling fibrous bodies at the tip are attached to the tip 2 in opposite directions. When screwed, the brush-shaped application body 6 is immersed in the application liquid L.
When not in use, the cap 9 is fitted to the front end 2.

The tip 3 is formed in a shell shape from stainless steel, and is fitted in a center hole 23 of the front end 2 as shown in FIG. In the ball house at the tip of the tip 3, a spherical coating body 4 made of a hard ball having a diameter of 1.0 mmφ is rotatably held with a part thereof protruding from the tip of the tip 3. Note that the chip 3 may be made of a metal pipe. In the tip 3, the spring force is 4
A small spring 7 of about 0 g is arranged. The spring 7 rebounds the spherical coating body 4 and presses the spherical coating body 4 against the inward leading edge 31 of the chip 3. Make up the mechanism.

As shown in FIG. 2, a large diameter fixing portion 51 is formed at the base end of the coating rod 5.
1 is fitted in the front end 2. An inner hole 52 is formed at the base end of the application rod 5, and a plurality of long holes 53 communicating with the inner hole 52 are formed on the peripheral surface of the application rod 5. The peripheral edge of the base end opening of the application rod 5 has a tapered shape, and forms a valve seat 54. Therefore, when the application tool is turned downward, the application liquid L in the application liquid tank 1 enters the inner hole 52 from the long hole 53 of the application rod 5 and is then supplied in the direction of the chip 3.

A plurality of projections 22 are formed in the front end 2, and a valve ball 8 is disposed between the projections 22 and the application rod 5. Therefore, when the applicator is turned downward, the valve ball 8 comes into contact with the projection 22, but the application liquid L is supplied into the chip 3 through the gap between the projections 22. On the other hand, when the applicator is turned upward, the valve ball 8 sits on the valve seat 54 of the applicator rod 5 as shown by the virtual circle in FIG. 2, and the application liquid L in the chip 3 flows back into the application liquid tank 1. Not to be.

When the application is performed with the spherical application body 4, the application liquid is turned downward by pressing the application liquid tank 1 with a fingertip to reduce the internal volume. Thereby, the coating liquid tank 1
Since the inside is pressurized, the coating liquid L having a high viscosity enters the inner hole 52 from the long hole 53 of the coating rod 5 as described above, and is then supplied to the spherical coating body 4 held at the tip of the chip 3. You. And apply it in the way of writing with a ballpoint pen,
When the applicator is a correction tool, small characters and the like can be finely corrected, and when it is a nail polish tool, a small pattern or the like can be drawn on the nail surface with a nail polish solution.

On the other hand, when applying with the brush-shaped applying body 6,
The tip 2 is removed from the application liquid tank 1 with the application tool facing upward. However, since the brush-shaped application body 6 was immersed in the application liquid L, the brush-type application body 6 contains the application liquid L. . Therefore, it suffices to apply the brush-shaped application body 6 while holding the tip end 2, and when the application tool is a correction tool, a wide range can be efficiently corrected. Nail polish can be applied in a similar manner. When the amount of the coating liquid L is small, the brush-shaped coating body 6 may not be immersed in the coating liquid L when the coating tool is left standing, but in this case, the coating is performed after the leading end 23 is removed. If the liquid tank 1 is tilted to guide the coating liquid L to the vicinity of the opening of the coating liquid tank 1, the brush-shaped coating body 6 is immersed in the coating liquid L so that the coating liquid L is contained in the brush-shaped coating body 6. Good.
