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. This invention relates to an applicator with a valve that can be easily adjusted.

(Problems to be solved by conventional techniques and inventions) Conventionally, as an applicator with a valve that stores the above-mentioned application liquid in the application liquid chamber, the main body is formed from a flexible material, and when in use, the applicator protrudes from the tip of the tip. The valve mechanism composed of the applicator and the inner surface of the tip body is created by pressing the tip of the applicator (made of synthetic resin and having a spiral-shaped part with elasticity from the middle part to the rear part) against the application surface. There is a known device in which the amount of coating liquid flowing out from the opening at the tip of the tip is adjusted by pressing the main body made of a flexible material in this state. Adjustment was based on the amount of pressure applied by the tip of the applicator against the application surface and the amount of pressure applied by the main body, so when the outside temperature rose, the interior of the application liquid chamber became pressurized, causing a large amount of application liquid to instantly flow out when the valve was opened. However, even during use, body temperature is transmitted, so it is difficult to adjust the pressure on the main body to make the appropriate amount of the coating liquid flow out. In order to solve these problems, it may be possible to make the aperture tip opening smaller, but if the opening is made smaller, a large amount of pressing force is required to make the coating liquid flow out. In addition, there were problems in that the outflow response of the coating liquid during pressing was poor, and phenomena such as smearing occurred due to insufficient outflow.

(Means for Solving the Problems) Therefore, in view of the above problems, the present invention provides a regulating part for the outflow amount of the coating liquid that is continuous with the valve mechanism at the tip of the acrobody, and also provides an intermediate part behind the regulating part. By providing a small chamber between the regulating part and the intermediate part inside the tip body, an applicator with a valve is provided that allows easy adjustment of the outflow amount of the application liquid and has good outflow response of the application liquid. There is no need to provide it.

That is, in the present invention, the agitator 3 is left in the coating liquid chamber 2.
A valve mechanism is composed of a main body 1 made of a flexible material having a body inside, a tip body 5 fixed to the tip of the body, and an inner surface of the tip body which is biased forward by an elastic body 7. In an applicator with a valve, which includes an applicator 6 protruding from the tip of the tip 5, the valve mechanism includes a seat 5b formed on the inner surface of the tip of the tip 5, and an applicator 6.
and a valve portion 6a formed at the tip of the tip body 5, and a rear portion 5 of the seat portion 5b of the tip body 5 at the rear of this valve mechanism.
f and the rear cylindrical portion 6d of the valve portion 6a of the applicator 6, a regulating portion 9 is formed which is continuous with the valve mechanism, and a flange portion 6c of the applicator 6 is formed.
and the inner surface 5 of the intermediate part of the tip body 5 facing the flange 6c.
A gap 10 is formed between g, and a small chamber 5c is formed in the tip body 5 to communicate with the regulating part 9 and the gap 10. be.

(Example) The present invention will be described in detail below based on an example shown in the accompanying drawings.

Reference numeral 1 is a main body made of a flexible material,
This main body 1 has an opening 1a and a coating liquid chamber 2 for storing correction fluid, ink, cosmetic liquid, etc. inside, and a stirring body 3 such as a sphere is left movably in this coating liquid chamber 2. are doing.

Reference numeral 4 denotes a cylindrical body fixed to the opening 1a of the main body 1, and the cylindrical body 4 has a rear receiving part for a resilient body 7, which will be described later, and a flange 4a, and the front end of the flange 4a is , the rear end of the collar 4a is pressed by an inner step 5a of the tip 5, which will be described later, which is fixed to the tip of the main body 1 by appropriate means such as screwing, press-fitting, adhesion, etc. It is pressed by the front end, and the pressure of the collar portion 4a in the front-rear direction prevents the coating liquid from leaking from the fixed portion between the main body 1 and the tip body 5. Incidentally, the cylindrical body 4 may be formed in one piece or may be composed of two parts.

6 has a conical valve part 6a at the tip and a cylindrical part 6b at the rear.
The coating body 6 is biased forward by an elastic body 7 such as a coil spring interposed between the flange 6c and the cylindrical body 4. , the applicator 6 connects its valve portion 6a to the tip body 5.
A conical seat portion 5b (valve portion 6a) formed at the tip of the inner surface of the
The cylindrical portion 6b of the applicator 6 is loosely inserted into the opening 4b of the cylindrical body 4 and is disposed within the tip body 5.

Reference numeral 8 denotes a coating liquid flow path 8 formed between the cylindrical portion 6b of the coating body 6 and the opening 4b of the cylindrical body 4. As shown in FIG. Although the shape is annular, the cylindrical portion 6b of the applicator 6
A groove in the longitudinal direction may be formed in the cylindrical body 4.
The form of the flow path can be changed in various ways, such as by forming a longitudinal groove on the inner surface of the opening 4b. Furthermore, in this example, the flow path 8 is located near the front end of the opening 1a of the main body 1, but depending on the physical properties of the coating liquid used, it may be positioned closer to the coating liquid chamber 2 than in this example. , it can also be located on the acrosome 5 side.

Note that the reason why the flow path 8 is constituted by the cylinder 4 and the cylinder portion 6b of the applicator 6 which is movably inserted loosely into the opening 4b of the cylinder 4 is to prevent the application liquid from sticking in the flow path 8. This is a consideration to prevent the coating liquid chamber 2 from
Depending on the type of coating liquid stored in the cylinder body 4.
The flow path 8 may be formed by reducing the diameter of the opening 4b.

Reference numeral 9 indicates the rear portion 5f of the seat portion 5b of the tip body 5 and the applicator body 6.
The regulating part 9 is formed by a small gap between the valve part 6a and the rear cylindrical part 6d and is continuous with the valve mechanism.As shown in FIG. However, similar to the above-mentioned flow path 8, the form can be changed in various ways.

Reference numeral 10 denotes a flange portion 6c of the application body 6, and the flange portion 6c.
A small chamber 5c is formed in the tip body 5 between the inner surface 5g of the middle part of the tip body 5 facing the gap 10 and the regulating portion 9. The regulating portion 9 and the intervening portion 10 communicate with the small chamber 5c.

11 is a cap, and 11a is a rib formed on the inner surface of the cap opening, which can be fitted and fixed with the rib 5e formed on the rear outer surface of the tip body 5 and the rib 1b formed on the rear outer surface of the main body 1. It is.

Next, the effect will be explained.

When in use, the main body 1 is turned downward and shaken up and down, and after the coating liquid in the coating liquid chamber 2 is stirred by the stirring body 3, the tip of the coating body 6 protruding from the tip of the tip body 5 is brought into contact with the coating surface, When pressed against the elastic force of the elastic body 7, the valve mechanism (valve portion 6a and seat portion 5b) opens. When the main body 1 is pressed, the coating liquid in the coating liquid chamber 2 passes through the flow path 8 and the tip body 5 where the elastic body 7 is located, and the outflow amount is adjusted by the gap 10, and an appropriate amount is sent into the small chamber 5c. It will be leaked. When pressed further, the coating liquid stored in the small chamber 5c is buffered by the air in the small chamber 5c, and its outflow amount is further adjusted by the regulating part 9. Between the outer surface of the tip and the tip, an appropriate amount flows out onto the coating surface via the tip opening 5d of the tip 5.

That is, in the present invention, when the main body 1 is pressed, the coating liquid in the coating liquid chamber 2 is regulated by the intermediate part 10, buffered in the small chamber 5c, and further regulated by the regulating part 9, and continues to the regulating part 9 and released. Since an appropriate amount of liquid flows out from the tip opening 5d of the tip body 5 through the valve mechanism, the coating liquid in the coating liquid chamber 2 does not directly flow out from the tip opening 5d of the tip body 5. It is easy to adjust the flow rate of the coating liquid by pressing, and even when the external temperature rises, the coating liquid in the coating liquid chamber 2 directly flows out from the tip opening 5d of the tip body 5 when the valve is opened. The pressure state is buffered by flowing into the small chamber 5c. Therefore, when the valve is opened, a large amount of the coating liquid will not flow out instantly.

(Effects) Since the applicator with a valve according to the present invention has the configuration as explained above, the coating liquid in the coating liquid chamber does not directly flow out from the opening at the tip of the tip body, but only flows through the gap. It is stored in the chamber and then flows out to the tip opening of the main body through the valve mechanism which is connected to the regulating part 9 and opened while being regulated by the regulating part, so that when the valve is opened, a large amount of application liquid is instantly released by the pressure of the main body. There is no outflow, the amount of outflow can be easily adjusted, and the outflow responsiveness of the coating liquid can be improved.
