Description

[Detailed description of the device]

[0001]

[Industrial application]

 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 has the applicator attached to the tip of the application liquid tank formed of a flexible material, and the valve mechanism is arranged behind the applicator. In many cases, the coating surface is pressed to open the valve, and in this state, the coating liquid tank is pressed to supply the coating liquid with high viscosity to the coating body. If the coated body is spherical, insert the spherical coated body from the back into a pipe-shaped tip with the tip edge swaged inward to expose a part of the spherical coated body from the tip of the tip, and spring it out. In many cases, the tip of the movable element is biased forward. In other words, when not in use, the spherical applicator is brought into close contact with the inward tip edge of the tip, and a valve structure is formed by the spherical applicator and the tip edge of the tip to prevent the correction fluid from being discharged.

[0003]

[Problems to be solved by the device]

 In such an applicator, when the tip of the spherical applicator is pressed against the application surface during application, the spherical applicator retracts and separates from the tip edge of the tip to open the valve, but since the tip is pipe-shaped, it strongly When pressed, the spherical applicator will be completely immersed in the chip. Therefore, the valve is opened widely, and the coating liquid is excessively discharged. In other words, there is a problem that it is difficult to control the discharge amount because the discharge amount changes depending on the pressure applied to the coating surface.

In addition, at the time of application, the spherical application body rotates by contacting with the tip end surface of the mover that is spring-backed, but the contact area is small, and the mover is spring-backed and moved. Since it is possible, it is unstable, and the spherical coated body does not rotate smoothly, which makes it difficult to coat. Further, since the spring and the mover are required, there is a problem that the number of parts is increased.

Therefore, the present invention has an object to provide an applicator that has a small number of parts, can easily control the ejection amount, does not excessively eject, and can apply smoothly. .

[0006]

[Means for Solving the Problems]

 To achieve such purpose. In the applicator of the present invention, a chip holding a spherical applicator is connected to a highly flexible coating solution tank, and the coating solution tank is filled with a highly viscous film-forming coating solution. The chip has a coating liquid passage hole inside, and holds a spherical coating body rotatably in a state where a part of it is exposed from the tip in a ball house connected to the coating liquid passage hole, and is integrated with one end of the spring. The spherical applicator is urged forward with a rod-shaped mover that is formed into contact with the tip of the tip facing inward, and during application, the spherical applicator contacts the seat of the ball house and rotates. To do so.

[0007]

[Action]

 Since the spherical applicator is biased forward by the mover formed integrally with the spring, the spherical applicator adheres to the inward tip edge of the chip when not in use, but the correction fluid does not discharge. At the time of coating, since the spherical coating material comes into contact with the seat portion of the ball house and rotates, the spherical coating material does not largely sink into the chip, the discharge amount can be controlled easily, and no excessive discharge occurs. Moreover, it can be applied smoothly. Since the mover is integrally formed by extending one end of the spring, there is an advantage that the number of parts is reduced.

[0008]

【Example】

 The present invention will be described in detail below with reference to the embodiments shown in the drawings. In FIG. 1, a spherical coating body 1 is rotatably held at the tip of a chip 2 having a coating liquid passage hole 21 inside. The chip 2 is held by a holder 3, and the holder 3 is connected to a coating liquid tank 4 formed of a flexible material. Inside the holder 3, a spring 6 and a rod-shaped movable element 5 integrally formed by extending one end of the spring 6 are arranged, and the movable element 5 is inserted into the chip 2. A cylindrical insert 7 is press-fitted into the holder 3, and the other end of the spring 6 is in contact with the insert 7. Therefore, the mover 5 is elastically bulged forward. Then, from the inside of the coating liquid tank 4 to the coating liquid passage hole 21, for example, a coating liquid which is a correction liquid having a viscosity of 30 to 40 cps and high film-forming property is filled.

Here, as shown in FIG. 2, the spherical coating 1 is movably held in the ball house 22 of the tip 2 made of stainless steel in a range of, for example, 5 to 15 μm in the front-rear direction, A part of it protrudes from the tip edge 26 of 2. The ball house 22 communicates with the coating solution passage hole 21, the center hole 23, and the vertical grooves 24 formed radially. The mover 5 inserted into the coating liquid passage hole 21 is slightly projected from the seat 25 of the ball house 22, that is, when the spherical applicator 1 moves in the front-back direction by, for example, about 5 to 15 μm. The spherical applicator 1 is biased forward in a state of being in contact with 25, whereby the spherical applicator 1 is in contact with the tip edge 26 of the tip 2.

Next, to give specific examples of dimensions, the spherical coating 1 is made of a superhard ball having a diameter of 0.7 mmφ, and the inner diameter of the ball house 22 is 0.72 to 0.73 mmφ. Further, the spherical coating 1 is loaded into the ball house 22 and then the tip edge 26 of the chip 2 is crimped and held. After the crimping, the tip of the spherical coating 1 is pressed with a punch to make the ball house 22. The seat 25 of 10 is submerged by 10 ± 3 μm and plastically deformed. Therefore, the spherical coated body 1 can move in the front-back direction within the range of 7 to 13 μm. Thus, the gap between the spherical applicator 1 and the ball house 22 is small for an applicator using a highly viscous coating liquid.

However, in use, when the coating liquid tank 4 is pressed with a fingertip to reduce the internal volume, the coating liquid adheres to the outer circumference of the spherical coating body 1. Then, when the spherical applicator 1 is moved while pressing it along the application surface, the spherical applicator 1 moves backward against the elastic force of the spring 6 and rotates while being in contact with the seat portion 25, so that application can be performed. In this way, since the spherical applicator 1 rotates while being in contact with the seat portion 25, the rotation is smooth, and therefore the application can be carried out smoothly. Further, since the spherical coating body 1 immediately contacts the seat portion 25, the coating liquid will not be excessively discharged. Further, since the mover is integrally formed by extending one end of the spring, the number of parts is reduced and the structure is simplified.

[0012]

[Effect of the device]

 As described above, in the applicator of the present invention, the mover that repels the spherical applicator is formed integrally with the spring, and the retracting spherical applicator immediately contacts the seat of the ball house of the tip during application. Since it is made to rotate, the number of parts is small, the discharge amount can be easily controlled, and it is possible to provide an applicator capable of applying smoothly without excessive discharge.
