DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art An applicator having a spherical applicator has a tip attached to a tip of a coating liquid tank filled with a coating liquid through a tip, and like a ballpoint pen, a tip is partially attached to the tip. The spherical application body is held rotatably in a state where it comes out from the tip. Then, the spherical application body is repelled by a spring, and when not in use, the spherical application body is brought into close contact with the inward tip edge of the chip, and a valve structure is formed by the spherical application body and the tip edge of the chip so that the application liquid is not discharged. Like that.

[0003] In use, when the spherical coated body is pressed against the coated surface, the spherical coated body retreats against the resilience of the spring, and a gap is formed between the spherical coated body and the tip edge of the chip. The coating liquid adhering to the inside of the chip of the coating body is applied to the outside of the chip through this gap with the rotation of the spherical coating body and is applied, but since the viscosity of the coating liquid is high, the coating liquid is in a natural state. Is not sufficiently supplied to the surface of the spherical coated body. For this reason, the coating liquid tank is blow-molded with a flexible material to make it deformable, and when used, the coating liquid tank is pressed with a fingertip to pressurize the inside, and the pressure is used to apply the coating liquid to the surface of the spherical coated body. To supply.

[0004] Even when the applied body is rod-shaped, a tapered portion in the middle of the applied body is formed, and the tapered portion of the applied body, which is repelled by a spring, is brought into close contact with the inward leading edge of the chip, and the rod-shaped applied body is formed. A valve structure is formed by the tip of the body and the tip to prevent the application liquid from being discharged. When the application body is pressed against the application surface, the application body retreats against the elastic force of the spring, and a gap is formed between the tapered portion of the application body and the tip edge of the chip. When the inside is pressurized by applying pressure, the application liquid is supplied to the application body and application becomes possible.

[0005] As described above, it is necessary to press the coating liquid tank with a fingertip to pressurize the inside during use, so that the operation is complicated, and the manufacturing cost is increased because the coating liquid tank is blow-molded with a flexible material. There is a problem that increases.

[0006]

For this reason, a cap pressing method has been put to practical use. This is because when the cap is attached, the cap can be further pushed in with the cap sealing the tip of the chip, and if the volume of the sealed space in the cap is reduced, the pressure in the cap increases. The pressurized air in the cap enters the coating solution tank, and the inside of the coating solution tank is pressurized.
In use, there is no need to press the coating liquid tank with a fingertip.

However, since the application body is repelled by the spring, in order for the air in the inner cylinder to enter the application liquid tank, it is necessary to overcome the elasticity of the spring and retreat the application body. . Therefore, it is necessary to sufficiently increase the pressure in the cap. That is, it is necessary to increase the pushing distance of the cap in a state in which the tip seals the tip of the chip, and there is a problem that the cap becomes longer and it is difficult to perform the pressing operation.

Therefore, according to the present invention, when the cap is mounted, the air in the cap can easily enter the coating liquid tank to pressurize the coating liquid tank, and it is not necessary to press the coating liquid tank with a fingertip during use. The purpose of the present invention is to provide an applicator with low manufacturing cost.

[0009]

In order to achieve the above object, the present invention provides a method of manufacturing a semiconductor device, in which an application body is held in a state where a part of the application body is protruded from a tip end opening of a chip, and the application body is elastically moved by a spring. It is emitted and contacts the inward leading edge of the chip, the tip holding the chip is connected to the coating solution tank,
The coating liquid tank is filled with a highly viscous film-forming coating liquid, and the annular projection formed on the outer peripheral surface of the front end slides on the inner peripheral surface of the cap when the cap is attached. A spherical sealing member made of a material with high flexibility is arranged, and a minute step is formed on the inner peripheral surface of the cap. In the process of attaching the cap, the coating body is retracted when it comes into contact with the tip of the sealing member. When the tip of the tip contacts the stepped portion of the cap, and the cap is pushed in further, the elastically deformed seal member is attached to the tip of the tip. Close the opening.

[0010]

[Function] That is, in the process of attaching the cap,
Since the annular projection formed on the outer peripheral surface of the front end slides on the inner peripheral surface of the cap, the air in the closed space of the cap is pressurized, but the applied body comes into contact with the tip of the spherical seal member. As a result, the spherical application body retreats by the reaction and separates from the inward tip edge of the chip, and the valve mechanism opens. Therefore, the pressurized air in the cap easily enters the coating solution tank and is pressurized. At this time, the cap mounting operation is performed because the annular projection of the leading end contacts the minute step of the cap. Stop once. In other words, the time when the ball mechanism is open and the valve mechanism is open away from the inward tip edge of the chip and retreats,
The pressurized air in the cap surely enters the coating liquid tank. Then, when the cap is further pushed in and the cap is completed because the annular projection of the leading end gets over the minute step of the cap, the sealing member is largely elastically deformed and closes the tip opening of the tip. The pressurized state in the liquid tank is maintained, and there is no need to press the coating liquid tank with a fingertip during use.

[0011]

Embodiments of the present invention will be specifically described below with reference to the drawings. In FIG. 1, a front end 2 having an annular projection 21 formed on an outer peripheral surface is connected to a tip of a coating liquid tank 1 injection-molded with a normal hard synthetic resin. The tip 3 is fitted in the tip opening of the front end 2. The tip 3 is formed in a shell shape from stainless steel, and holds the spherical coating body 4 at its tip.
Note that the chip 3 may be made of a metal pipe.

FIG. 2 shows a state in which the spherical coated body 4 is rotatably held by the chip 3. The spherical coated body 4 is made of a carbide ball having a diameter of, for example, 1.0 mm. It is arranged in the house 32. Ball house 32
Is formed by the center hole 33 and the vertical groove 34.
6, the spherical coated body 4 retreats and rotates while contacting the seat 35 of the ball house 32 at the time of coating. A spring 5 composed of a coil spring is arranged in the chip 3.
And press it against the inward leading edge 31 of the chip 3,
The spherical coating body 4 and the tip end 31 of the chip 3 constitute a valve mechanism. Here, the spring load of the spring 5 is 5
300 g. A coating liquid having a viscosity of, for example, 30 to 40 cps and having a high film forming property is filled from the inside of the coating liquid tank 1 connected to the front port 2 and the inside of the front port 2 to the chip 3.

The cap 6 is formed of a synthetic resin into a cylindrical shape with a bottom. As shown in FIG. 3, a plurality of vertical ribs 63 are formed at the back bottom, and the vertical ribs 63 are highly flexible. A spherical sealing member 7 made of a material is held. The inner peripheral surface on the abutment side of the cap 6 is a cylinder portion 61 on which the annular projection 21 of the front end 2 slides when the cap is attached. When the cylinder portion 61 comes into close contact with the annular projection 21 of the front end 2, the inside of the cap 6 is It becomes a sealed space.

A step 6 is provided at the end of the cylinder 61.
2 are formed. The stepped portion 62 is formed at a position where the spherical application body 4 comes into contact with the seal member 7 and slightly retreats when the annular projection 21 of the front end 2 comes into contact with the stepped portion 62. The step portion 62 is minute as shown in FIG.
The height from the cylinder 61 is, for example, 0.05 mm.

When the cap 6 is attached to the front opening 2, first, as shown in FIG.
Is in close contact with the end of the cylinder portion 61, and the inside of the cap 6 becomes a sealed space. When the cap 6 is further pushed in from this state, the annular projection 21 slides in a state of being in close contact with the cylinder portion 61, and the volume of the sealed space in the cap 6 is reduced. Is done.

Then, as shown in FIG.
Abuts against the tip of the seal member 7, and the spherical coating body 4 is retracted by the repulsive force of the seal member 7. At this time, when the annular projection 21 abuts on the step portion 62 and the cap 6 is attached with a normal pushing force, the pushing of the cap 6 is temporarily stopped by the resistance. Since the spherical coating body 4 has receded, a gap is formed between the spherical coating body 4 and the tip edge 31 of the chip 3, as shown in FIG. Although the liquid enters the liquid tank 1, since the pushing of the cap 6 is temporarily stopped, there is a time margin for the pressurized air in the cap 6 to enter the coating liquid tank 1. The inside of the coating liquid tank 1 is pressurized easily and reliably.

Next, when the pusher is further pushed in from the state shown in FIG. 6, the annular projection 21 gets over the step portion 62, and the abutment end 64 of the cap 6 comes into contact with the step surface 22 of the front end 2, and as shown in FIG. Then, the mounting of the cap 6 is completed. At this time, the sealing member 7 formed into a spherical shape with a material having high flexibility is largely elastically deformed, and closes the tip opening of the tip 3 as shown in FIG. Therefore, the pressurized state is maintained in the coating liquid tank 1.

As described above, when the cap 6 is mounted, the spherical coating body 4 is forcibly retracted by the sealing member 7 to form a gap between the spherical coating body 4 and the tip edge 31 of the chip 3. Since the state is temporarily maintained, the air in the cap 6 easily and reliably enters the coating liquid tank 1 without increasing the pressure inside the cap 6 too much.
The inside of the coating liquid tank 1 is pressurized. Therefore, when the cap 6 is removed for coating, the coating liquid is sufficiently supplied to the spherical coating body 4. In other words, there is no need to press the coating liquid tank 1 with a fingertip, and the coating can be reliably applied in the manner of writing with a ballpoint pen. Further, since the sealing member 7 is spherical, there is an advantage that there is no directionality, the assembling is easy, and the dimensional error is easily absorbed. And since it is spherical, there is clearance for clearance, and the seal member 7 is less likely to undergo plastic deformation.

[0019]

As described above, in the applicator according to the present invention, in the process of attaching the cap to the front end, the applicator comes into contact with the tip of the sealing member, and the spherical applicator recedes due to the reaction, and the chip As the valve mechanism opens and this state is temporarily maintained, the pressurized air in the cap easily enters the coating liquid tank, The inside of the tank is pressurized. When the mounting of the cap is completed, the elastically deformed seal member closes the tip opening of the chip, so that the pressurized state in the application liquid tank is maintained. Therefore, there is no need to press the coating liquid tank with a fingertip at the time of use, and furthermore, it is not necessary to blow-mold the coating liquid tank with a flexible material, and injection molding can be performed with a normal hard synthetic resin, so that it can be manufactured at low cost. There are advantages that can be.
