Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to an applicator with a valve that stores a coating liquid such as correction fluid, ink, cosmetic liquid, etc. The present invention relates to an applicator with a valve that can be easily adjusted and that can discharge an appropriate amount of coating liquid even when coating a small area.

(Prior art) Conventionally, as an applicator with a valve that stores the above-mentioned application liquid in the application liquid chamber, the main body is made of a flexible material, and when in use, the tip of the applicator that protrudes from the tip of the main body is pressed against the coating surface. It is known that the valve is opened by pressing the main body made of a flexible material in this state to adjust the amount of the coating liquid that flows out from the opening at the tip of the main body. However, when the outside temperature rises, When the coating liquid chamber becomes pressurized, a large amount of coating liquid may instantly flow out when the valve is opened, and body heat is transmitted even during use, making it difficult to adjust the pressure on the main body to allow the appropriate amount of coating liquid to flow out. However, some problems remained. In order to solve these problems, it may be possible to make the opening amount of the opening at the tip of the main body very small, but if the opening amount is made very small, a large amount of pressing force will be required to make the coating liquid flow out. In addition to this, there was also the problem that phenomena such as fading occurred due to insufficient outflow.

Therefore, the present applicant has provided an outflow amount regulating section at the tip of the main body and a restraining section between the coating liquid chamber and a sub-chamber provided in front of this coating liquid chamber, thereby making it possible to adjust the outflow amount by pressing the main body. First applied for an applicator with a valve that made it easier to apply (Utility Model Publication No. 62-29103)
did.

(Problem to be solved by the invention) However, although the above invention has made it easier to adjust the coating liquid by pressing the body, it is difficult to simply press the tip of the coating body against the coating surface when coating a small area. There was a problem in that the amount of the coating liquid discharged was small, and if the tip of the applicator was pressed against the coating surface while pressing the main body, the amount of the coating liquid was too large and it was difficult to adjust the amount of discharge.

(Means for Solving the Problems) Therefore, in order to solve the above problems, the inventor of the present invention has conducted intensive research and found that when applying to a small area, the tip of the application body should be placed on the application surface without pressing the main body. The present invention was completed by discovering a structure that makes it possible to discharge an appropriate amount of coating liquid just by pressing. That is, the present invention consists of a main body made of a flexible material having a coating liquid chamber inside, a tip body fixed to the tip of the main body, and a tip that is urged forward by an elastic body so that the tip protrudes from the opening of the tip body. An applicator with a valve includes an applicator body disposed with a valve part formed at the tip part pressed against a seat part in the tip body, a cylindrical part behind the seat part in the tip body, and the applicator body. A regulating part is formed in a small space between the valve part and the rear cylindrical part, and a sub-chamber communicating with the regulating part is provided in the tip body, and an opening communicating the sub-chamber and the application liquid chamber; A valve-equipped applicator is provided, characterized in that a restraining part is formed in a small space between the applicator body and the cylindrical part at the rear thereof, and the spatial cross-sectional area of the restricting part is larger than the spatial cross-sectional area of the restraining part. This is a summary.

(Structure of the invention) The present invention will be described in detail below based on embodiments shown in the accompanying drawings.

Reference numeral 1 is a main body made of a flexible material,
The main body 1 is formed with an opening 2 and a coating liquid chamber 3 for storing correction fluid, ink, cosmetic liquid, etc. In the coating liquid chamber 3, a stirring sphere (not shown) is provided as needed. ) are left movable. 4 is a cylindrical body, and this cylindrical body 4 is press-fitted into the opening 2 of the main body 1;
The front end of the collar 4a is pressed by the inner step 5a of the tip 5, which is fixed to the front end of the main body 1 by an appropriate fixing means such as press-fitting or adhesive, and the rear end of the collar 4a is pushed into the opening 2 of the main body 1. is placed in contact with the front end of the

is biased forward by an elastic body 7 such as a coil spring stretched between the rear end of the flange 6c and the front end of the cylinder 4, and the tip of the applicator 6 is pushed through the opening of the tip body 5. 5e and the valve portion 6a of the applicator 6.
A conical seat portion 5b formed at the inner tip of the tip body 5
The cylindrical portion 6b of the applicator 6 is loosely inserted into the opening 4b of the cylindrical body 4, and is disposed in the subchamber 5c in the tip body 5. Reference numeral 8 denotes a regulating portion formed by a minute gap between a cylindrical portion 5d behind the seat portion 5b of the tip body 5 and a cylindrical portion 6d behind the valve portion 6a of the application body 6. Reference numeral 9 denotes a restraining part formed by _a minute gap between the cylindrical part 6b of the applicator 6 and the opening 4b of the cylindrical body 4. area
It is larger than S ₂ .

(effect) Next, the effect will be explained.

When in use, the main body 1 is turned downward, and the tip of the applicator 6 that protrudes from the tip of the main body 1 is brought into contact with the coating surface and pressed against the elastic force of the elastic body 7. When the main body 1 is pressed, the flow rate of the coating liquid in the coating liquid chamber 3 is adjusted by the restraining part 9, and an appropriate amount flows out into the auxiliary chamber 5c. When pressed further, the coating liquid accumulated in the subchamber 5c is buffered by the air in the subchamber 5c,
The outflow amount is further regulated by the regulating portion 8, so that the appropriate amount flows out onto the coating surface.

That is, in the present invention, when the main body 1 is pressed, the coating liquid in the coating liquid chamber 3 is regulated by the suppressing part 9, and the coating liquid in the subchamber 5 is adjusted.
Since the coating liquid in the coating liquid chamber 3 directly flows out from the tip opening 5e of the tip body 5, the coating liquid is buffered within c and further regulated by the regulating part 8 to flow out from the tip opening 5e of the tip body 5. This makes it easy to adjust the amount of coating liquid coming out by pressing the main body 1, and even when the external temperature rises, the coating liquid in the coating liquid chamber 3 is directly transferred to the tip when the valve is opened. The pressure state is buffered by flowing into the subchamber 5c without flowing out from the tip opening 5e. Therefore, when the valve is opened, a large amount of the coating liquid will not flow out instantly.

Moreover, since the spatial cross-sectional area S ₁ of the regulating part 8 is larger than the spatial cross-sectional area S ₂ of the suppressing part 9, when applying a small area, the main body 1 is pressed and the pressure in the subchamber 5c is reduced. When the pressure of the main body 1 is released and the tip of the application body 6 is pressed against the application surface, pressure is applied to the application liquid stored in the subchamber 5c, but the restriction part 8
Since the cross-sectional area of the space is larger than that of the suppressing part 9, it is easier for the coating liquid to flow, and furthermore, when the tip of the coating body 6 is pressed against the coating surface, the tip opening 5e almost suppresses the discharge of the coating liquid. Therefore, an appropriate amount of the coating liquid flows out smoothly from the acrosome opening 5e. Therefore, it is suitable for application to a small area, so-called spot application.
