Abstract

(57) [Abstract] [Purpose] To provide an applicator in which the discharge amount can be easily controlled, the liquid can be applied smoothly without excessive discharge. In a coating tool in which a highly flexible coating liquid tank 4 is connected to a tip 2 made of a metal pipe holding a spherical coating body 1, a spherical coating body 1 is partially attached to a ball house 22 from the tip. The tip end surface of the mover 5, which is held in a freely protruding state and freely rotatably held by the spring 6, and which is slightly ejected into the ball house 22, biases the spherical applicator 1 forward to move the tip of the tip 2 inside. The spherical applicator 1 is brought into contact with the seat portion 21 and rotated during the application, by contacting the tip end edge 23 in the facing direction.

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 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.

Therefore, an object of the present invention is to provide an applicator in which the discharge amount can be easily controlled, the liquid can be applied smoothly without excessive discharge.

[0006]

[Means for Solving the Problems]

 To achieve such purpose. In the applicator of the present invention, a highly flexible coating liquid tank is connected to a chip made of a metal pipe holding a spherical coating body, and the coating liquid tank is filled with a highly viscous film-forming coating liquid. In the applicator, the peripheral surface near the tip of the tip is recessed to form a seat, and the ball applicator in front of this seat is provided with a spherical applicator that can rotate freely while a part of it is exposed from the tip. The spherical applicator is urged forward by the tip surface of the mover that is held and springed by the spring and slightly protrudes into the ball house to contact the inward tip edge of the chip. The body should rotate in contact with the seat of the tip.

[0007]

[Action]

 Since the spherical applicator is biased forward by the tip surface of the mover that is spring-backed, the spherical applicator is closely attached to the inward tip edge of the tip made of metal pipe when not in use. Although the correction fluid is not discharged, the spherical coating material rotates in contact with the seat part of the ball house during coating, so the spherical coating material does not largely sink into the chip, and the discharge amount can be controlled easily and excessively. It can be applied smoothly without being discharged.

[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 applicator 1 is rotatably held at the tip of a tip 2 made of a stainless steel pipe. 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 chip 2, a mover 5 having a small mass is arranged. Further, a cylindrical insert 7 is press-fitted into the holder 3, a spring 6 is interposed between the insert 7 and the radial projection 51 of the mover 5, and the mover 5 springs forward. Has been done. The coating liquid, which is a correction liquid having a viscosity of 30 to 40 cps and high film-forming property, is filled from the inside of the coating liquid tank 4 to the chip 2.

Here, seat portions 21 are formed on the peripheral surface of the same circle in the vicinity of the tip of the tip 2 on the same circle, for example, at three regular intervals, and a seat 21 is formed in front of the seat 21. The spherical applicator 1 is movably held in the ball house 22 of the chip 2 in the front-rear direction within a range of, for example, about 5 to 15 μm, and a part thereof is exposed from the tip edge 23 of the chip 2. . The front portion 5a of the mover 5 inserted between the seat portions 21 is slightly projected into the ball house 22, that is, when the spherical coating body 1 moves in the front-back direction by, for example, about 5 to 15 μm. The spherical applicator 1 is urged forward in a state of contacting the portion 21, so that the spherical applicator 1 is in contact with the tip edge 23 of the tip 2.

To give a specific example of the dimensions, the spherical coated body 1 is made of a superhard ball having a diameter of 0.7 mmφ, and the inner diameter of the pipe-shaped chip 2, that is, the inner diameter of the ball house 22 is 0. 72 to 0.73 mmφ. Further, the spherical applicator 1 is loaded into the ball house 22 and then the tip edge 23 of the chip 2 is crimped and held, but after caulking, the tip of the spherical applicator 1 is pressed with a punch and the seat of the ball house 22 is seated. Part 21 is submerged by 10 ± 3 μm and plastically deformed. Therefore, the spherical coating 1 can be moved 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.

In use, however, when the coating liquid tank 4 is pressed with a fingertip to reduce the internal volume, the coating liquid in the chip 2 adheres to the outer circumference of the spherical coating body 1. When the spherical applicator 1 is moved while pressing it along the application surface, the spherical applicator 1 retreats against the elastic force of the spring 6 and rotates while being in contact with the seat portion 21, so that application can be performed. As described above, since the spherical applicator 1 rotates while in contact with the seat portion 21, 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 21, the coating liquid does not discharge excessively.

[0012]

[Effect of the device]

 As described above, in the applicator of the present invention, the retracting spherical applicator is brought into immediate contact with the seat portion of the ball house of the pipe-shaped tip to rotate during application, so that the discharge amount can be controlled. The applicator can be easily applied and can be applied smoothly without excessive ejection.
