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]

 An applicator with a spherical applicator has a tip made of, for example, a metal pipe attached to the tip of an application liquid tank that is made of a flexible material and filled with the application liquid. The spherical applicator is rotatably held with a part of it protruding from the tip. Then, the coating liquid in the coating liquid tank is supplied to the surface of the spherical coating body and is coated on the coating surface by rotating the spherical coating body on the coating surface. In many cases, the tip of the child is biased forward. That is, when not in use, the spherical applicator is brought into close contact with the inward tip edge of the tip, and the valve structure is constituted 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, since the size of the tip made of a metal pipe is much smaller than that of the coating solution tank, the tip is attached to a holder and this holder is connected to the coating solution tank. Then, a rod-shaped mover is placed in the holder, and the thin tip portion of the holder is inserted into the tip 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 for moving 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, 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 has a high film-forming property. In the applicator filled with the coating solution, the tip of the tip is recessed in the peripheral surface near the tip to form a seat, and a part of the spherical applicator protrudes from the tip in the ball house in front of this seat. In this state, the spring is held so that it can be freely rotated, and a spring with a small mass is placed in the tip.The spherical applicator is repelled by this spring and comes into contact with the inward tip edge of the chip. Contacts the seat of the tip and allows it to rotate.

[0006]

[Action]

 Since the spherical applicator is biased forward by the spring, when not in use, the spherical applicator adheres to the inward tip edge of the tip made of a metal pipe and the correction fluid does not discharge, but the mover is omitted. Since the spring is placed inside the tip made of metal pipe to reduce its mass, the inertial force of the spring is small even when a large impact is applied. Therefore, the force with which the spring 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 tip 2 made of a stainless steel pipe having an inner diameter of 1.05 mmφ has a diameter of 1. A spherical applicator 1 made of a 0 mmφ carbide ball is rotatably held. 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 cylindrical insert 6 is press-fitted into the holder 3. A spring 5 having a small mass is arranged in the tip 2, and one end of the spring 5 is received by the insert 6 to repel the spherical coating body 1 forward. As a result, the spherical coated body 1 is in contact with the tip edge 23 of the tip 2 deformed inward. Then, from the inside of the coating liquid tank 4 to the chip 2, the coating liquid, which is a correction liquid having a viscosity of 30 to 40 cps and high film-forming property, is filled.

Here, seat portions 21 are formed on the peripheral surface of the same circle in the vicinity of the tip of the chip 2 on the same circle, for example, at three regular intervals, and the front of the seat portion 21 is the ball house 22. 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 80 to 100 μm, and a part thereof is exposed from the tip edge 23 of the chip 2. .

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 periphery of the spherical coating body 1. When the spherical applicator 1 is moved while being pressed along the application surface, the spherical applicator 1 retracts against the elastic force of the spring 5 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 spring 5 is also impacted, and a forward inertial force acts on the spring 5, so that the spherical applicator Press 1 forward. However, since the spring 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.

[0011]

[Effect of device]

 As described above, in the applicator of the present invention, the mover for contacting the spherical applicator with the tip edge of the chip made of a metal pipe is omitted, and the spring having a small mass is arranged in the tip. It is possible to provide an applicator in which the spherical applicator does not fall off the chip even when a large impact is applied to the tip.
