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, which has a spherical applicator, has a tip attached to the tip of a coating liquid tank filled with the coating liquid through the tip, and like a ball-point pen, a part of the tip is exposed from the tip. The spherical applicator is rotatably held in the extended state. Then, the spherical applicator is repelled by a spring, and when not in use, the spherical applicator is brought into close contact with the inward tip edge of the chip, and the spherical applicator and the tip end edge of the chip form a valve structure so that the coating liquid does not discharge. I am trying.

When the spherical applicator is pressed against the application surface during use, the spherical applicator retreats against the elastic force of the spring and a gap is created between the spherical applicator and the tip edge of the chip. The coating liquid adhering to the inside of the tip of the spherical applicator passes through this gap and is applied to the outside of the chip as the spherical applicator rotates.However, since the viscosity of the coating liquid is high, it is applied in a natural state. The liquid is not sufficiently supplied to the surface of the spherical coated body. For this reason, the coating liquid tank can be blow-molded with a flexible material to make it deformable, and when in 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 surface of the spherical coating. Is being supplied to.

As described above, since it is necessary to press the coating liquid tank with a fingertip to pressurize the inside during use, 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 becomes high.

[0005]

[Problems to be solved by the device]

 For this reason, when the cap is mounted, if the inner cylinder of the cap seals the tip of the chip and the cap can be pushed further, and the volume of the sealed space in the inner cylinder is reduced, the pressure in the inner cylinder will be reduced. Get higher Therefore, the air in the inner cylinder invades the coating solution tank and pressurizes the coating solution tank, so that it is not necessary to press the coating solution tank with a fingertip during use.

However, since the spherical applicator is elastically ejected by the spring, in order to allow the air in the inner cylinder to enter the coating solution tank, it is necessary to overcome the elastic force of the spring and retract the spherical applicator. There is. Therefore, it is necessary to sufficiently increase the pressure in the inner cylinder. In other words, it is necessary to increase the pushing distance of the cap when the inner cylinder seals the tip of the chip, which makes the inner cylinder of the cap longer and makes it difficult to perform the pressing operation.

Therefore, in the present invention, when the cap is attached, the air in the inner cylinder can be easily infiltrated into the coating liquid tank to pressurize the coating liquid tank, and it is necessary to press the coating liquid tank with a fingertip during use. It is an object of the present invention to provide an applicator that is free of manufacturing costs and has low manufacturing costs.

[0008]

[Means for Solving the Problems]

 In order to achieve such an object, the present invention rotatably holds a spherical applicator in a state where a part of the applicator is exposed from the tip end of the tip, and the spherical applicator is springed by a spring to tip the tip. The tip of the tip that holds the tip is connected to the coating liquid tank, the coating liquid tank is filled with the highly viscous film-forming coating liquid, and the ring-shaped protrusion is formed on the outer periphery of the tip. In the applicator in which the tip is in close contact with the inner peripheral surface of the inner tube of the cap and the tip is made of a highly flexible material, the valve opening member is placed in the inner tube of the cap. When the spherical applicator comes into contact with the tip of the valve stick of the valve opening member in the process of mounting the tip, it retracts and separates from the inward tip edge of the tip, and when the cap mounting is completed, the tip stick is removed. It bends and abuts the side of the tip, restoring the spherical coating. Tsu to be in contact with the inward of the leading edge of flops.

[0009]

[Action]

 That is, in the process of mounting the cap, the spherical applicator comes into contact with the tip of the push rod of the valve opening member, so that the reaction causes the spherical applicator to retreat and separate from the inward tip edge of the tip, opening the valve mechanism. . Therefore, the pressurized air in the inner cylinder easily enters the coating solution tank and is pressurized. When the cap is completely attached, the protruding rod bends and comes into contact with the side of the chip, the spherical applicator restores and the valve mechanism closes, and the pressurized state is maintained. There is no need to press the liquid tank with your fingertips. Since 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, it is possible to manufacture at a low cost.

[0010]

【Example】

 The present invention will be described in detail below with reference to the embodiments shown in the drawings. In FIG. 1, a tip 3 is fitted in the tip opening of a front opening 2 having an annular projection 21 formed on the outer circumference of the tip. The tip 3 is formed of stainless steel in a bullet shape, and a part of the spherical coating 4 made of a super hard ball with a diameter of 1.0 mm protrudes from the tip of the tip 3 in the ball house at the tip of the tip 3. It is embraced in a freely rotatable state. The tip 3 may be made of a metal pipe.

A small spring 5 having a spring force of 40 g is arranged in the tip 3, and the spring 5 repels the spherical applicator 4 and presses it against the inward tip edge 31 of the tip 3 to form a spherical shape. The applicator 4 and the tip edge 31 of the tip 3 form a valve mechanism. The front port 2 is integrally connected to the coating liquid tank 1. The coating liquid tank 1 is injection-molded from a normal hard synthetic resin, and its manufacturing cost is lower than that of a liquid blow-molded from a flexible material. Then, from the inside of the coating liquid tank 1 and the front port 2 to the chip 3, the coating liquid, which is a repairing liquid having a viscosity of 30 to 40 cps and having a high film-forming property, is filled.

The cap 6 is made of synthetic resin, and as shown in FIG. 2, an inner cylinder 7 is integrally formed inside. When the inner peripheral surface of the tip edge 7a of the inner cylinder 7 comes into close contact with the annular projection 21 of the front opening 2, the inner cylinder 7 becomes a sealed space. The valve opening member 8 is arranged inside the inner cylinder 7. The valve opening member 8 is formed of a highly flexible material, and the thrust rod 8 1 is integrally projected. The thrust rod 81 is provided at a position slightly displaced from the center of the valve opening member 8, and the tip 81a of the thrust rod 81 is an inclined surface.

When the cap 6 is attached to the front opening 2, the tip edge 7a of the inner cylinder 7 comes into close contact with the annular projection 21 of the front opening 2 in the process, and the inside of the inner cylinder 7 becomes a sealed space. If the cap 6 is pushed further in this direction from this state, the inner peripheral surface of the inner cylinder 7 slides in close contact with the annular protrusion 21 and the volume of the sealed space inside the inner cylinder 7 decreases. Therefore, the air in the inner cylinder 7 is pressurized. Then, as shown in FIG. 2, the spherical applicator 4 contacts the tip 81a of the thrust rod 81, but when pushed in this state, the spherical applicator 4 retreats due to the repulsive force of the thrust rod 81. That is, since a gap is formed between the spherical applicator 4 and the tip edge 31 of the tip 3, the air in the inner cylinder 7 enters the coating solution tank 1 and the interior of the coating solution tank 1 is pressurized.

When the joint end 61 of the cap 6 comes into contact with the step surface 11 of the coating liquid tank 1 by further pushing in from the state shown in FIG. 2, the mounting of the cap 6 is completed as shown in FIG. At this time, the flexible stick 81 bends and comes into contact with the tip side portion of the tip 2, and the spherical applicator 4 does not come into contact with the stick 81. Therefore, the spherical applicator 4 comes into contact with the tip edge 31 of the chip 3 again by the resilience of the spring 5, and the pressurized state in the coating liquid tank 1 is maintained.

In this way, when the mounting of the cap 6 is completed, the air in the inner cylinder 7 easily enters the coating liquid tank 1 without raising the pressure in the inner cylinder 7 so much that the coating liquid tank 1 The inside is pressurized. Therefore, when the cap 6 is removed and coating is performed, the coating liquid is sufficiently supplied to the spherical coating body 4. That is, it is not necessary to press the coating liquid tank 1 with a fingertip, and it is possible to reliably apply the coating liquid tank 1 by writing with a ballpoint pen.

[0016]

As described above, in the applicator of the present invention, the spherical applicator comes into contact with the tip of the stick of the valve opening member in the process of mounting the cap on the front opening, and the spherical applicator reacts to the spherical shape. Since the applicator retracts and separates from the inward tip edge of the tip to open the valve mechanism, the pressurized air in the inner cylinder easily enters the coating solution tank, Pressurized. Therefore, it is not necessary to press the coating liquid tank with a fingertip at the time of use, and it is not necessary to blow mold the coating liquid tank with a flexible material. It can be manufactured.
