Constitution: A tip 2 holding a spherical applicator 1 is connected to a highly flexible coating liquid tank 4, and the coating liquid tank 4 is filled with a highly viscous film-forming coating liquid. The spherical applicator 1 is rotatably held inside the tip of the tip while a part of the tip is exposed from the tip, and a mover 5 having a small mass is arranged in the tip 2 so that the spring 6 repels the mover. The spherical applicator 1 is biased forward by the tip surface of the child 5 so as to come into contact with the inward tip edge 26 of the tip 2.

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 applicator is spherical, insert the spherical applicator from the back into the tip with the tip edge swaged inward to expose a part of the spherical applicator from the tip of the tip, and the mover springed by the spring. Many of them are urged forward by the tip surface of. 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, the size of the chip is much smaller than that of the coating liquid tank, so the chip is attached to a holder and this holder is connected to the coating liquid tank. Then, the rod-shaped mover is arranged in the holder, and the thin tip portion of the holder is inserted into the chip to urge the spherical applicator forward. That is, the mover is larger than the spherical applicator and has a large mass. For this reason, when a large impact is applied to the applicator such as when the applicator is dropped on the floor, the inertial force that moves the mover forward increases, and the spherical applicator is strongly pressed forward. Therefore, there is a problem that the spherical coating material breaks the inward tip edge of the chip and falls off.

Therefore, an object of the present invention is to provide an applicator in which the spherical applicator does not fall off even when a large impact is applied to the applicator.

[0005]

[Means for Solving the Problems]

 In order to achieve such an object, the applicator of the present invention is such that a chip holding a spherical applicator is connected to a highly flexible coating liquid tank, and the coating liquid tank has a highly viscous film-forming coating liquid. In the applicator filled with, the spherical applicator is rotatably held inside the tip of the tip with a part of it protruding from the tip, and a mover with a small mass is arranged in the tip. The tip of the mover, which is spring-backed, urges the spherical applicator forward so that it contacts the inward tip edge of the tip.

[0006]

[Action]

 Since the spherical applicator is urged forward by the tip surface of the mover that is spring-backed, the spherical applicator adheres to the inward tip edge of the chip when not in use, and the correction fluid is not discharged. However, since the mover is placed inside the chip to reduce its mass, the inertial force of the mover is small even when a large impact is applied. Therefore, the force with which the mover presses the spherical applicator is weak, and the spherical applicator does not fall off the tip of the chip.

[0007]

【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 shell-shaped tip 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. A mover 5 having a small mass is arranged in the coating liquid passage hole 21 of the chip 2, and the front portion 5a of the mover 5 is inserted into the ball house 22 of the chip 2. Further, a cylindrical insert 7 is press-fitted into the holder 3, a small spring 6 is interposed between the insert 7 and the mover 5, and the mover 5 is elastically bulged forward. The coating liquid tank 4 is filled with the coating liquid, which is a repair liquid having a viscosity of 30 to 40 cps and a high film-forming property, from the inside of the coating liquid tank 4 to the coating liquid passage hole 21.

Here, the spherical coating body 1 is movably held in the ball house 22 of the tip 2 made of stainless steel in the front-rear direction within a range of, for example, about 5 to 15 μm, and from the front edge 26 of the tip 2. A part of it appears. The ball house 22 communicates with the coating solution passage hole 21, the center hole 23, and radial grooves 24. The mover 5 arranged in the coating liquid passage hole 21 slightly protrudes from the seat portion 25 of the ball house 22, that is, the spherical coating body 1 moves in the front-back direction by, for example, about 5 to 15 μm. Then, the spherical applicator 1 is biased forward while being in contact with the seat portion 25, whereby the spherical applicator 1 is in contact with the tip edge 26 of the tip 2.

Next, as a specific example of the size, 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.

Therefore, 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.

Here, if this applicator is dropped onto the floor with the tip 2 facing downward, the movable element 5 is also impacted and an inertial force acts in the forward direction on the movable element 5. Push the body 1 forward. However, since the mover 5 has a small mass, this inertial force is not strong. Therefore, the force for pressing the spherical applicator 1 forward is weak, the tip edge 26 of the tip 2 is not deformed, and the spherical applicator 1 does not fall off.

[0012]

As described above, in the applicator of the present invention, the mover for contacting the spherical applicator with the tip edge of the tip is arranged in the tip to reduce its mass, so that the applicator is subjected to a large impact. It is possible to provide an applicator in which the spherical applicator does not drop off from the chip even when it is exposed.
