Abstract

PROBLEM TO BE SOLVED: To stabilize the discharging of an application liquid by regulating a pressure in an application liquid tank, and at the same time, reduce the cost by arranging a pressurizing tank in the application liquid tank, expanding a closing body by pressu rizing air in the pressurizing tank by a knocking operation, and pressurizing the inside of the application liquid tank by making air enter the tank. SOLUTION: A through-hole 71 of an air compressing member 7 is closed with a finger, and when a knock-pressing operation is performed, a deforming section 72 deforms and the internal volume of the air compressing member 7 reduces. In this case, accompanying the closing of the through-hole 71, the inside of a pressurizing tank 5 becomes a hermetic space, and accompanying the reduction of the internal volume of the air compressing member 7, the internal air of the pressurizing tank 5 is pressurized. Then, when the air pressure in the pressurizing tank 5 has reached a specified value or higher, a closing body 6 opens, and the closing of a vent hole 51 is released, and the air in the pressurizing tank 5 passes through the vent hole 51 and enters an application liquid tank 1, and the inside of the application liquid tank 1 is pressurized. By this constitution, even when the pigment of the application liquid is separated and deposited, the application liquid in the application liquid tank 1 can be pressurized.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention
The present invention relates to an applicator filled with a coating liquid having a high viscosity in which a pigment is dispersed in a solvent.

[0002]

2. Description of the Related Art An applicator having a spherical applicator has a tip attached to the tip of a coating liquid tank filled with a high-viscosity coating liquid in which a pigment is dispersed in a solvent, through a tip, and a ball-point pen. Similarly, the spherical coating body is held rotatably in a state where a part of the tip comes out of the tip 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, conventionally, the coating liquid tank is blow-molded with a flexible material so as to be deformable, and at the time of use, 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 spherical coated body. To the surface. However, since the application liquid tank is blow-molded with a flexible material, there is a problem that the manufacturing cost is increased.

Therefore, recently, a cap press type applicator has been put to practical use. With a cap pressurizing applicator, the coating liquid tank is injection molded with a hard synthetic resin, and when the cap is fitted, the air in the pressurized cap enters the coating liquid tank from the tip of the chip and is applied. The inside of the liquid tank is pressurized.

[0005]

As described above, the applicator of the cap pressurizing method can be manufactured at a low cost because the application liquid tank is injection-molded with a hard synthetic resin. There is an advantage that the operation is simple because there is no need to press the inside to pressurize the inside. However, since the fitting of the cap is usually performed after the application work is completed,
When applying a wide coating area, the pressure in the coating liquid tank drops on the way and the discharge of the coating liquid deteriorates. Conversely, if a small amount of coating is applied and the cap is Pressure may become too high and the coating liquid may drop. In other words, the cap pressurizing applicator has a problem in that it is difficult to keep the pressure in the applicator tank optimal, and the ejection of the applicator liquid is not stable.

For this reason, a pressurized tank is provided at the tail end of the coating liquid tank, and the vent hole of the pressurized tank is closed with a closing member made of a soft elastic material. It is conceivable that the closing body is opened and the air in the coating liquid tank enters the coating liquid tank and is pressurized.

However, in the coating liquid filled in the coating liquid tank, the pigment is dispersed in the solvent. If the coating tool is left at a store for a long time, for example, the pigment separates from the solvent and precipitates. And form a cake. When the closing member made of the soft elastic body is covered with the cake, the closing member does not operate even if the inside of the pressurizing tank is pressurized even if the knocking operation is performed, and the pressurizing in the application liquid tank is impossible. become.

Accordingly, the present invention has a low manufacturing cost, can appropriately adjust the pressure in the coating liquid tank, stabilizes the discharge of the coating liquid, and adds pressure to the coating liquid tank even if the pigment of the coating liquid separates and settles. An object of the present invention is to provide an applicator that can be pressed.

[0009]

In order to achieve the above object, a first aspect of the present invention is to provide a spherical coating body in which a spherical coating body is rotatably held with a part of the spherical coating body protruding from the tip of a chip. A coating liquid tank in which the body is repelled by a spring and contacts the inward leading edge of the chip, filled with a high-viscosity film-forming coating liquid in which a pigment is dispersed in a solvent, and a built-in coating liquid stirring member. In the applicator with a chip connected to it, a cylindrical pressurized tank having a vent hole at the tip is arranged from the tail end to the tip of the application liquid tank injection-molded with a hard synthetic resin. At the same time, when the air holes are closed with a closing member made of a soft elastic body and the chip is left in an upward position with the coating liquid unused, the closing body is separated from the pigment separated and settled in the coating liquid. So that it is located at the top and pressurized by knocking And expanding air to be pressurized closure in ink penetrates into the coating solution in the tank through the vent holes, the coating liquid in the tank is to be pressurized.

[0010] Further, as in the second aspect of the present invention, when the distal end surface of the pressurized tank is covered with a closing member made of a soft elastic material, the applicator is shaken up and down, and when the application liquid is agitated by the agitating member, the agitation is performed. The member can abut against the obstruction to reduce the impact.
Furthermore, as in the invention of claim 3, the coating liquid stirring member is
When the applicator is stirred, the spherical or rod-shaped first stirring member that moves up and down between the tip of the pressurized tank and the chip and the gap between the outer peripheral surface of the pressurized tank and the inner peripheral surface of the coating liquid tank move up and down. If it is made of a cylindrical second stirring member, the coating liquid can be effectively stirred.

[0011]

Embodiments of the present invention will be specifically described below with reference to the drawings. In FIG.
The tip 3 is fitted in the opening at the tip of the device. Chip 3
A spherical coating 4 made of a carbide ball having a diameter of, for example, 1.0 mmφ is formed in a ball house at the tip of the tip 3 with a part thereof protruding from the tip of the tip 3. Held freely in rotation. In addition,
The tip 3 may be made of a metal pipe. A small-mass spring (not shown) is arranged in the chip 3.
And presses against the inward leading edge of the chip 3.
That is, a valve mechanism is formed by the spherical coating body 4 and the tip edge of the chip 3 so that the coating liquid is not discharged from the tip of the chip 3 when not in use.

The tip 2 into which the chip 3 is fitted is 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. From the inside of the coating liquid tank 1 and the front end 2 to the chip 3, for example, the viscosity is 30 to 40 cps and the solvent S
Coating liquid L, which is a correction liquid having a high film forming property in which pigment G is dispersed in
Is filled. Then, for example, when the chip 3 is displayed in an upward attitude at a store and left for a long time, the pigment G separates from the solvent S and sediments. When not in use, the cap 9 is fitted to the front end 2.

A pressurized tank 5 is formed integrally with the coating liquid tank 1 from the tail end to the tip end of the coating liquid tank 1. The pressurized tank 5 has a cylindrical shape, and is provided with, for example, two radial ventilation holes 51 at its tip. At the tip of the pressurized tank 5, a closed-end cylindrical closed body 6 made of a soft elastic body, for example, silicone rubber, is inserted.
1 is closed and the bottom surface also covers the front end surface of the pressurized tank 5. However, when the air force in the pressurized tank 5 increases, the closing body 6 expands to release the closing of the ventilation hole 51. Therefore, the inside of the pressurized tank 5 and the inside of the coating liquid tank 1 communicate with each other through the ventilation hole 51, and the air in the pressurized tank 5 enters the coated liquid tank 1. That is, the closing body 6 plays a role of “sadness”.

Here, as shown in FIG. 1, when the coating liquid L is not used, that is, when the amount of the coating liquid L is the maximum, the pigment G is separated from the solvent S by turning the chip 3 upward. The length of the pressurized tank 5 is set such that the closing body 6 is located above the pigment G even if the sedimentation occurs. Therefore, even if the sedimented pigment G solidifies to form a cake, the plug 6
Is not covered with cake.

The tail end opening of the pressurized tank 5 is
Covered with. The air compression member 7 is formed of a soft elastic body and has high flexibility, and has a through hole 71 at a tail end. Therefore, the inside of the pressurized tank 5 communicates with the outside through the through hole 71. A deformed portion 72 formed in a slightly thin bellows shape is provided at a middle portion of the air compression member 7. Further, inside the coating liquid tank 1, a spherical or rod-shaped first stirring member 81 that moves up and down between the tip of the pressurizing tank 5 and the chip 3, and the outer peripheral surface of the pressurizing tank 5 and the inside of the coating liquid tank 1 A cylindrical second stirring member 82 that moves up and down in a gap with the peripheral surface is arranged.

When the application is started, first, the applicator is shaken up and down, the application liquid L is stirred by the first stirring member 81 and the second stirring member 82, and the pigment G is uniformly dispersed in the solvent S. Let it. At this time, the first stirring member 81 collides with the distal end surface of the pressurized tank 5, but since the distal end surface of the pressurized tank 5 is covered with the closing member 6 made of a soft elastic body, the impact of the collision is reduced. You. The gap between the outer peripheral surface of the pressurized tank 5 and the inner peripheral surface of the coating liquid tank 1 can also be efficiently stirred by the second cylindrical stirring member 82.

When the discharge of the coating liquid is reduced at the start of coating or during the coating operation, as shown in FIG. 2, a knocking operation is performed in which the finger 71 presses the air compressing member 7 with the through hole 71 closed. The internal volume of the air compression member 7 is reduced by deforming the deformation portion 72 of the air compression member 7. At this time, since the through hole 71 of the air compression member 7 is closed with the fingertip, the inside of the pressurized tank 5 becomes a closed space. Air is pressurized. Then, when the air pressure in the pressurized tank 5 becomes equal to or higher than a predetermined value, as described above, the closing body 6 expands and the blockage of the ventilation hole 51 is released. As a result, the liquid enters the coating liquid tank 1 and is pressurized.

Here, when the pigment G is separated from the solvent S and settles with the chip 3 facing upward in a state where the coating liquid L is not used, the closing member 6 is positioned above the pigment G and settles. Even if the pigment G solidified and the cake is formed, the closing body 6 is not covered with the cake. Therefore, when the air pressure in the pressurized tank 5 exceeds a predetermined value by the knocking operation, the closing body 6 operates normally. Then, the blockage of the ventilation hole 51 is released.

When the pressing operation is released, the inside of the pressurizing tank 5 communicates with the atmosphere through the through hole 71, so that the air compressing member 7 returns to its original position promptly by its own elasticity, and the closing member 6 is closed. The air holes 51 are closed, and the state returns to the state shown in FIG. When the ejection of the application liquid is not sufficient by one pressing operation, this pressing operation may be repeated as necessary. Conversely, if you want to slightly pressurize the coating liquid tank 1,
The pressing operation may be released halfway without deforming the air compression member 7 to the end.

As described above, since the pressure in the coating liquid tank 1 can be appropriately adjusted by the pressing operation of the air compressing member 7, a good and stable discharge of the coating liquid can be obtained. Also,
Since the coating liquid tank 1 is not formed by blow molding with a flexible material but is formed by injection molding with a hard synthetic resin, it can be manufactured at low cost. Further, even if the pigment G is separated from the solvent S and solidified, the closing member 6 operates normally and the ventilation holes 51 are formed.
Can be released, and the inside of the application liquid tank 1 can be pressurized.

As described above, according to the present invention, the spherical coated body is rotatably held with a part of the spherical coated body protruding from the tip of the chip, and the spherical coated body is resiliently resiliently spring-loaded. In contact with the inward leading edge of the coating liquid is filled with a highly viscous film-forming coating liquid in which a pigment is dispersed in a solvent, and a coating tool in which a chip is connected to a coating liquid tank containing a coating liquid stirring member. A cylindrical pressurized tank having a vent at the tip is disposed from the tail end to the tip of the coating liquid tank injection-molded with a hard synthetic resin, and the vent is formed from a soft elastic body. When the chip is closed with an obstruction and the chip is left in an upright position in a state where the application liquid is not used, the obstruction is positioned above the separated and settled pigment in the application liquid, and the knocking operation is performed. Pressurizes the air in the pressurized tank and blocks it The coating liquid is expanded into the coating liquid tank through the vent hole and pressurizes the coating liquid tank, so that the manufacturing cost is low, the pressure in the coating liquid tank can be adjusted appropriately, and the discharge of the coating liquid is stabilized, An applicator that can be pressurized even when the liquid pigment separates and sediments.
