BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an applicator filled with a high-viscosity coating liquid such as a correction liquid, a cosmetic liquid, an adhesive, and Peyton.

[0002]

2. Description of the Related Art In the above-mentioned applicator, an application body is attached to the tip of a coating liquid tank, and a valve mechanism is arranged behind the application body. In many cases, a high-viscosity coating liquid is supplied to a coating body in this state. And, when the coated body is spherical, the spherical coated body is inserted from the back into the chip whose tip edge is crimped inward, and a part of the spherical coated body is exposed from the tip of the chip, and the movable element is repelled by a spring. Often, the tip surface is biased forward. That is, when not in use, the spherical coating body is brought into close contact with the inward tip edge of the chip, and a valve structure is formed by the spherical coating body and the tip edge of the chip so that the correction liquid is not discharged.

[0003]

In such an applicator, since the size of the chip is much smaller than that of the application liquid tank, the chip is mounted on a holder and this holder is connected to the application liquid tank. The rod-shaped mover is disposed in the holder, and the thin tip of the holder is inserted into the chip to urge the spherical application body forward. That is, the mover is larger and has a larger mass than the spherical coated body. For this reason, when a large impact is applied to the applicator, such as when the applicator is dropped on the floor, the inertia force of the mover moving forward increases, and the spherical applicator is strongly pressed forward. Therefore, there is a problem that the spherical coating body breaks the inward leading edge of the chip and falls off.

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

[0005]

In order to achieve the above object, the present invention provides an applicator in which a coating liquid tank is connected to a chip holding a spherical coating body, and a highly viscous film-forming coating is applied to the coating liquid tank. In a liquid-filled applicator, a spherical movable body is held inside the tip of the chip in a freely rotatable manner with a part of it protruding from the tip, and a small mass mover and a spring are arranged inside the chip. The movable member repelled by the spring urges the spherical coating body forward to come into contact with the inward leading edge of the chip. In addition, a seat is formed inside the chip so that the spherical coating body rotates in contact with the seat during coating.

[0006]

[Function] Since the spherical application body is urged forward by the movable element repelled by the spring, the correction liquid is not discharged because the spherical application body adheres to the inward tip edge of the chip when not in use. Since the mover and the spring are arranged in the chip to reduce the mass thereof, the inertia of the mover and the spring is small even when a large impact is applied. Therefore, the force with which the mover and the spring press the spherical coating body is weak, and the spherical coating body does not fall off the tip of the chip.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to the embodiments shown in the drawings. In FIG. 1, a tip 3 is fitted into a tip end opening of a holder 2 whose tip portion is a sealing portion 21 having a small diameter. Then, the holder 2 is integrally connected to the coating liquid tank 1. The coating liquid tank 1 is injection-molded with a normal hard synthetic resin, and its manufacturing cost is lower than that obtained by blow-molding a flexible material.
Then, a coating liquid having a viscosity of, for example, 30 to 40 cps and a high film forming property is filled from the inside of the coating liquid tank 1 and the holder 2 to the chip 3.
A high-viscosity coating liquid such as a cosmetic liquid, an adhesive, or Peyton may be used.

The cap 7 is formed of a synthetic resin, and has an inner tube 8 integrally formed therein. And
When the inner peripheral surface of the leading edge of the inner cylinder 8 comes into close contact with the outer peripheral surface of the sealing portion 21 of the holder 2, the inside of the inner cylinder 8 becomes a sealed space, and the chip 3 is sealed.

The chip 3 is formed in a shell shape from stainless steel, and a spherical coating body 4 made of a carbide ball having a diameter of 1.0 mmφ is partially provided in a ball house at the tip of the tip 3. It is freely rotatable while protruding from.

Here, as shown in FIG. 2, the spherical coated body 4 is movable within the ball house 32 of the chip 3 made of stainless steel in a shell shape in the longitudinal direction, for example, within a range of about 15 to 30 μm. It is held, and a part of the tip 3 projects from the leading edge 36 of the tip 3. The ball house 32 communicates with the application liquid passage hole 31 through a center hole 33 and a radially formed vertical groove 34. And the coating liquid passage hole 3
A small mover 5 and a small spring 6 having a spring force of, for example, 40 g are arranged in 1. That is, chip 3
A spring 6 is interposed between the projection 37 at the tail end and the mover 5, and the front surface 5a of the mover 5 urged by the spring 6 urges the spherical coating body 4 forward, whereby the spherical The coated body 4 comes into contact with the tip edge 36 of the chip 3 and the spherical coated body 4
The valve mechanism is constituted by the tip edge 36 of the tip 3.

Thus, as shown in FIG.
Is inserted into the long inner cylinder 8, in the process, the leading edge of the inner cylinder 8 comes into close contact with the outer peripheral surface of the sealing portion 21 of the holder 2,
The inside becomes a sealed space. When the cap 7 is further pushed in from this state, the inner peripheral surface of the inner cylinder 8 slides in a state of being in close contact with the outer peripheral surface of the sealing portion 21, and the volume of the sealed space in the inner cylinder 8 decreases. The air in the cylinder 8 is pressurized. Therefore,
This pressure causes the spherical coated body 4 to retreat, and the spherical coated body 4
There is a gap between the tip 3 and the tip edge 36 of the chip 3, so that the air in the inner cylinder 8 enters the coating liquid tank 1 and the inside of the coating liquid tank 1 is pressurized. Therefore, when the cap 7 is removed for coating, the coating liquid is sufficiently supplied to the spherical coating body 4.
Therefore, in use, it is not necessary to press the coating liquid tank 1 with a fingertip. When the coating liquid tank 1 is moved while being pressed along the coating surface, the spherical coating body 4 to which the coating liquid has sufficiently adhered causes the resilience of the spring 6. The roller retreats against the seat portion 35 and rotates in contact with the seat portion 35, so that it is possible to reliably apply the ink by writing with a ballpoint pen.

Alternatively, as shown in FIG. 3, a seat or a ball house may be formed on the chip 3, and the distal end surface of the mover 5 may be used as the seat. Further, the chip 3 may be made of a metal pipe.

Here, if the applicator is dropped on the floor with the tip 3 down, the impact is also applied to the movable element 5 and the spring 6, and the forward inertia force is applied to the movable element 5 and the spring 6. Works, and presses the spherical coating body 4 forward. However, since the mass of the mover 5 and the spring 6 is small, the inertia force is not strong. Accordingly, the force for pressing the spherical coating body 4 forward is weak, and the tip edge 36 of the chip 3 is not deformed, and the spherical coating body 4 does not fall off.

[0014]

[Effects of the Invention] As described above, the applicator of the present invention is a movable element for bringing the spherical application body into contact with the tip edge of the chip.
In addition, since the spring for resiliently moving the mover is arranged in the chip to reduce the mass thereof, the coating device can be prevented from falling off the chip even if a large impact is applied to the coating device.
