Description

[Detailed description of the invention] [Industrial field of application] The present invention is a container for storing coating fluids such as ink and correction fluid, and more specifically, a container for storing coating fluids such as ink and correction fluid, and more specifically, a container that is made of a flexible material and has an opening at the tip end of a tube on the front side of the container. A valve mechanism in which a valve rod with a tip protruding from the tip is pressed against the tip tube by a spring body, and the coating liquid in the container can be applied by pressing the portion protruding from the tip tube against the application surface. The present invention relates to an improvement of an applicator having the following features.

[Problems that conventional technologies and ideas try to solve]

As an applicator of this type having a valve mechanism, there is a commercially available product (vertical sectional view, FIG. 12) in which the distal end of a plastic valve rod A is used as an applicator.

When in use, the tip of the coating body protruding from the tip of the tip (front barrel) is pressed against the coating surface against the elastic force of the spring body (spring body), and the main body made of a flexible material is pressed. By pressing the (container), the coating liquid flows out from the tip of the tip body (front tube), but since the coating liquid outflow adjustment function is performed only by the valve mechanism C, the amount of coating liquid flowing out is controlled. It is very difficult to adjust and has the disadvantage that the coating liquid drips.

As a solution to these shortcomings, Jitsukaisho
An applicator shown in No. 59-35087 has been developed (an example drawing of the invention is shown in FIG. 13, and a longitudinal sectional view of a commercially available product is shown in FIG. 14). These are equipped with a middle part (suppressing part) E having a suppressing function at the opening of the main body (container). ], the coating liquid is stored in the tip body (front tube) through the middle tool E, and then flows out from the tip of the tip body (tip tube). ) in a position far away from the opening of the
Not only does it take time for the application liquid to pass through the inner tool (suppressing part) and reach the tip body (tip tube) opening, but even when the body (container) is shaken, there is a small gap. A middle tool E having a suppressing part composed of
The coating solution in the room is in front of the inner tool E, and the main body (container) is behind the inner tool E.
The disadvantage is that the coating liquid inside the coating liquid is not stirred uniformly, and the effect of stirring the coating liquid is reduced.

A vertical cross-sectional view of a commercially available product similar to the one described above is shown in No. 15.
As shown in the figure.

By the way, in the valve rods shown in Figs. 13 to 15, a flange is formed on the valve lever to receive the projectile (spring), but these only serve the role of spring holders. However, in any case, the flow rate of the coating liquid is not adjusted at this flange, and the flange shown in FIGS. 13 and 14 is clear from both drawings. As shown, a plurality of recesses are formed around the periphery, and the coating liquid passes through these recesses and reaches the tip. The coiled elastic body (spring body) is located at least in front of the coating liquid suppressing part, that is, between the collar part for the spring receiver and the inner fitting E.

In addition, in the case shown in FIGS. 14 and 15, the valve rod (coated body) is inserted into the through hole formed in the inner member E, and the inner circumferential surface of the through hole and the valve rod (coated body) are inserted. The minute gap between the outer circumferential surface of the body and the outer circumferential surface of the coating liquid acts as a suppressor for the coating liquid.

In addition to the case where the inner fitting E having a suppressing effect is provided at the opening of the main body (container), there is also a small gap between the cylindrical part of the applicator and the opening of the cylindrical body attached to the opening of the main body (container). There is also one in which a restraining part is formed with (for example, see Utility Model Application No. 59-7075). In this case as well, since the deterrent part is formed at the opening of the main body (container),
As with the case where the inner tool E is provided, not only does it take time for the coating liquid to pass through the suppressing part and reach the tip body (tip tube), but also the difference between the inside of the tip body (tip tube) and the main body (container). Because the restraining part with a small gap is located in the middle, the coating liquid in the chamber in front of the restraining part and the coating liquid in the main body (container) behind the restraining part are not evenly stirred. This has the disadvantage that the stirring effect is reduced. Further, since the coating liquid whose outflow amount is regulated by the suppressing portion formed of a minute gap is temporarily stored in the chamber in front of the suppressing portion, the outflow responsiveness of the coating liquid is also poor.

In the case of the applicator shown in Utility Model Application Publication No. 59-7075, there is a
In other words, a regulating section is provided in continuity with the valve mechanism [this regulating section consists of a small gap between the inner wall of the tip body (front tube) and the rear cylindrical section of the application body], and the above-mentioned suppressing section prevents the outflow. The flow rate of the adjusted coating liquid is further adjusted by the regulating portion.

[Means to solve the problem]

The present invention is an improvement on the conventional example described above, and has the synergistic effect of improving the mobility of the coating liquid in the container and increasing the stirring effect, allowing the coating liquid with high concentration and large hiding power to be transferred to the valve. The purpose is to allow the appropriate amount to flow out smoothly and quickly upon opening.

In order to achieve this object, the present invention has a front tube 4 or 4' on the front side of a container 1 made of a flexible material having a sphere 2 for stirring the coating liquid in a chamber 1a,
A valve rod 5 is provided with a packing 3 that supports a spring body 6 and whose tip protrudes from the tip opening of the front cylinder 4 or 4'.
The applicator has a valve mechanism pressed against the valve rod 5, and a bulge 5a is formed at a position rearwardly away from the valve mechanism part of the valve rod 5, and the surface of the bulge 5a and the bulge A gap 7 having a liquid volume suppressing function between the inner surface of the wall of the front cylinder 4 or 4' surrounding the outside of the part 5a.
The bulging portion 5a divides the inside of the front cylinder 4 or 4' into two front and rear chambers 4f and 4g with the gap 7 as a boundary, and in the chamber 4g immediately rearward of the gap 7. , the bulge 5a and the valve lever 5
The spring body 6 is supported between the receiver tubes 3a of the packing 3 into which the
g and the chamber 1a in the container 1 are communicated through the opening 3b of the packing 3, which does not have a liquid volume control function, and only one part of the gap 7 is used as a coating liquid outflow adjustment section in front of the chamber 1a in the container 1. That is.

That is, in the present invention, by shaking the container,
A configuration in which the coating liquid in the container is uniformly and well-stirred and mixed, and when the valve is opened, an appropriate amount of the coating liquid can immediately flow out in response to the opening without any stagnation. There are characteristics.

[Effect]

The method of using the applicator according to the present invention is no different from the conventional applicator, but in the case of the present invention,
A bulging portion 5a is formed at a position rearwardly away from the valve mechanism portion of the valve rod 5, and the surface of the bulging portion 5a and the bulging portion 5
A gap 7 having a liquid volume control function is formed between the inner surface of the wall surrounding the outside of the tube a, and the inside of the front cylinder 4 or 4' is 2.
The receiving tube 3a of the packing 3 is divided into two chambers 4f and 4g, and in the chamber 4g immediately behind the gap 7, the bulging portion 5a and the valve rod 5 are inserted.
The spring body 6 is supported in between, and the chamber 4g immediately behind the gap 7 and the chamber 1a in the container 1 are communicated through the opening 3b of the packing 3, which does not have a liquid volume suppressing function. There is no suppressing part for the coating liquid behind the gap 7, and the chamber 4g immediately behind the gap 7 and the chamber 1a in the container 1 are communicated through the opening 3b of the packing 3, which does not have a liquid volume suppressing function. Therefore, both chambers 4g and 1a function as if they were one chamber, and by shaking the applicator up and down several times before use, chamber 1a
Even if the pigment contained in the liquid is partially precipitated, the coating liquid in the chamber 4g will not be applied to the sphere 2 in the chamber 1a.
At the same time as the stirring effect, the mixture can be freely moved and replaced in both chambers 1a and 4g, and the mixture can be easily uniformized. When using, with the tip side of the applicator facing downward, place the applicator in the tip tube 4 or 4'.
When the tip of the valve rod 5 protruding from the tip opening 4a is brought into contact with the point to be corrected and pressed against the elastic force of the spring body 6, the container 1 is pressed with the finger.
The agitated and homogenized coating liquid in the chamber 4g has its outflow rate adjusted by the only gap 7, and smoothly and quickly reaches the tip from the chamber 4f in front of it, and is connected to the valve mechanism in response to the opening of the valve. The correction work is carried out by smoothly flowing out the appropriate amount from the tip opening 4a without any stagnation. In this way, when the valve is opened by pressing the valve rod 5 of the applicator during use, an appropriate amount of the homogenized coating liquid quickly flows out in response to the opening without stagnation, so that the outflow response of the coating liquid is improved. In addition to having extremely good properties,
Adjustment of the outflow amount is also easy.

On the other hand, the bulging portion 5a for forming the gap 7 also serves as a spring receiver for the spring body 6, and the receiving tube 3a of the packing 3 into which the valve rod 5 is inserted into the bulging portion 5a.
The front end of the spring body 6 located between the bulges 5a
The rear end of the spring body 6 is supported by the receiving tube 3a of the packing 3. And excuse 5

is located behind the gap 7 for adjusting the outflow amount of the coating liquid, and the coating liquid whose outflow amount is adjusted by the gap 7 smoothly and quickly reaches the tip from the chamber 4f in front of it. Become.

〔Example〕

Embodiments of the present invention will be described based on the accompanying drawings.

The container 1 is made of a flexible material such as plastic. This container 1 stores coating liquids such as ink and correction fluid, and contains a sphere 2 for stirring the coating liquid.

A packing 3 is attached to the mouth of the container 1 or halfway inside the container 1. 1 to 4 and 8 to 11 show packing 3 in container 1.
5 to 7 show a case in which a packing 3 is provided halfway inside the container 1 (described later).

A front tube 4 or 4' is provided on the front side of the container 1. Figures 1 to 4 and Figures 8 to 1
1 shows the case where the front tube 4 is screwed onto the packing 3 attached to the mouth of the container 1.
Any means other than screwing, fitting, etc. may be used to connect the two. Furthermore, FIGS. 5 and 6 show a case in which the tip of the container 1 is made thinner than the barrel portion, and a small tip tube 4' is fitted into that portion. Any method may be used for this, and as shown in FIG.
The tip of the container 1 may be integrally molded with the container 1 so that the tip of the container 1 becomes the tip tube 4 as it is.

In the center of the packing 3, a receiving tube 3a for the spring body 6 supported by, for example, a cross-shaped partition piece is formed. The chamber 1a and the chamber 4g in the container 1 are communicated through each opening 3b of the packing 3, and the two chambers function as if they were one chamber.

A valve lever 5 is disposed within the tip tube 4 or in a place that spans the narrowed part of the container 1 and the small tip tube 4' provided at the tip, and its tip is connected to the tip of the tip tube 4 or 4'. The lower end of the valve rod 5 is fitted into the receiving tube 3a of the packing 3. The tip of the valve stem 5 is pressed against the inner wall 4a of the tip opening of the tip cylinder 4 or 4' by a coiled spring 6.

The lower end of the spring body 6 is held in the receiving tube 3a of the packing 3. That is, the packing 3 functions as a so-called spring stopper. The packing 3 in the cases of Figs. 5 to 7 has only this spring locking function, but in the cases of Figs. 1 to 4 and Figs. That is, it can be said that it also has the function of sealing the joint between the container 1 and the front tube 4.

On the other hand, a bulge 5a is formed at a position rearwardly away from the valve mechanism part of the valve rod 5, and between the surface of the bulge 5a and the inner surface of the wall surrounding the outside of the bulge 5a. A gap 7 is formed between the bulging portion 5a and the front cylinder 4 or 4' is divided into two chambers 4, front and rear, with the gap 7 as a boundary.
It is divided into 7 parts f and 4 g, and this gap 7 part is used as an outflow adjusting part of the coating liquid. In the chamber 4g immediately behind this gap 7, the bulging portion 5a and the valve rod 5
The spring body 6 is positioned between the receiving tubes 3a of the packing 3 into which the spring body 6 is inserted, and its both ends are supported by the bulging portion 5a and the receiving tube 3a of the packing 3. In this way, the spring body 6 has a gap 7 for adjusting the amount of outflow of the coating liquid.
The coating liquid located further back and whose outflow amount is adjusted by the gap 7 smoothly and quickly reaches the tip from the chamber 4f in front of it.

By the way, as described above, the chamber 4g behind the gap 7 and the chamber 1a in which the sphere 2 for stirring the coating liquid is stored communicate through the opening 3b of the packing 3, which does not have a liquid volume control function. Both chambers function as if they were one chamber, and the coating liquid is stored in both chambers. Therefore, the gap 7 portion serves as the only coating liquid outflow adjusting portion in front of the chamber 1a. Further, as described above, the coating liquid that has passed through the gap 7 smoothly and quickly reaches the tip from the chamber 4f located in front of the gap 7, passes through the valve mechanism in response to the opening of the valve, and stagnates. It quickly flows out smoothly and in an appropriate amount from the tip opening 4a.

Among the embodiments, FIG. 5 shows a case where a gap 7 is formed between the tapered inner wall 1b of the tip end of the container 1 and the outer peripheral surface of the bulging part 5a of the valve rod 5, and FIG. This shows a case in which a gap 7 is formed between the step portion 4c formed on the inner wall of the cylinder 4 and the upper end surface of the bulging portion 5a of the valve rod 5.
A case is shown in which a gap 7 is formed between the valve rod 5 and the outer circumferential surface of the bulging portion 5a of the valve rod 5. This gap 7 is 4 in FIG.
d or may be partially closed at the tip as shown at 4e in FIG. In short, it is sufficient that at least the gap 7 is formed behind the closed portion.

By providing the bulging portion 5a on the valve rod 5, the front end of the spring body 6 can be engaged with the stepped portion immediately below the bulging portion 5a, and the bulging portion 5 for forming the gap 7 can be engaged with the step immediately below the bulging portion 5a.
A can be used as it is as a spring holder.

The bulging portion 5a provided on the valve rod 5 may be formed by integral molding with the valve rod 5 as in the embodiments shown in FIGS. A separate ring-shaped member may be attached to the valve rod 5.

Alternatively, the gap 7 may be formed by providing a linear or spiral groove on the surface of the bulge 5a of the valve stem 5 or on the inner surface of a wall surrounding the bulge 5a. In addition, although the gap 7 is located at about 1/4 of the total length of the applicator when viewed from the end of the tip cylinder 4 or 4', it may be located at a position far back from the valve mechanism of the valve rod 5. For example, the position can be changed as appropriate depending on the viscosity of the coating liquid.

Note that FIGS. 1 to 10 show the case where the tip of the plastic valve rod 5 is used as the coating body.
This application body may be made of fiber as shown at 10 in FIG.

In other drawings, 8 is a cap attached to the front tube 4 or 4' or the small-diameter stepped portion of the container 1, and 9 (FIGS. 5 to 7) is a cap attached to the small diameter step of the container 1.
It is a tail plug attached to the tail end of the.

Next, how to use this applicator will be explained.

After the coating liquid in the chamber 1a of the container 1 is stirred by the sphere 2, the tip of the valve body 5 protruding from the tip of the front cylinder 4 or 4' is pressed against the application surface against the elastic force of the spring body 6. Further press the container 1. Then,
Opening 3b of packing 3 without liquid volume control function
The coating liquid stirred in the chambers 4g and 1a, which are connected to each other and function as if they were one chamber, is adjusted to flow out for the first time at the gap 7, and immediately flows into the chamber 4f in front of the gap 7. It flows smoothly and quickly from this chamber 4f to the tip, and in response to the opening of the valve, the inner wall 4a of the tip opening of the tip cylinder 4 or 4' and the tip of the valve rod 5 or the fiber-made An appropriate amount is allowed to flow out smoothly from between the coating body 10 and the coating body 10. In this way, the coating liquid can be applied to the coating surface.

By the way, the chamber 4g behind the gap 7 and the container 1
The inner chamber 1a communicates with the inner chamber 1a through the opening 3b of the packing 3, which does not have a liquid volume control function, and both chambers function as if they were one chamber.
When the coating liquid in the chamber 1a is stirred by the sphere 2 by shaking, the coating liquid in the chamber 4g and the coating liquid in the chamber 1a are evenly and uniformly stirred.
The stirring effect is extremely large. When the container 1 is pressed, the coating liquid that has been evenly stirred in the chambers 4g and 1a is adjusted to flow out for the first time in the gap 7, and the coating liquid that has been adjusted to flow out in the gap 7 immediately flows to the front of the gap 7. It flows out into the chamber 4f, from which it smoothly and quickly reaches the tip, and in response to the opening of the valve, it flows smoothly and in appropriate amounts without any stagnation through the valve mechanism.

[Effect of idea]

In the present invention, a bulging portion 5a is formed at a position remote from the valve mechanism portion of the valve rod 5 rearwardly, and the surface of the bulging portion 5a and the inner surface of the wall surrounding the outside of the bulging portion 5a are connected. A gap 7 is formed in between, but there is no coating liquid suppressing part behind this gap 7, and the chamber 4g behind the gap 7 and the chamber 1a in the container 1 have a liquid volume suppressing function. Since they are connected through the opening 3b of the packing 3, which does not have a Even if some of the pigment contained in the coating liquid is precipitated, the coating liquid remains in the chamber 1a.
At the same time as the stirring effect by the inner sphere 2, the insides of both chambers 1a and 4g can be freely moved and replaced, which facilitates homogenization. When in use, with the tip of the applicator facing downward, place the tip of the valve rod 5 protruding from the tip opening 4a of the tip tube 4 or 4' in contact with the location to be corrected, and apply the spring body 6.
When the container 1 is pressed against the elastic force of the container 1 and the container 1 is pressed with a finger, the amount of the agitated and homogenized coating liquid in the chamber 4g is adjusted by the only gap 7, and the flow rate of the agitated and homogenized coating liquid in the chamber 4g is adjusted by the only gap 7. From there, it reaches the tip smoothly and quickly, and in response to the opening of the valve, it passes through the valve mechanism and promptly flows out smoothly and in an appropriate amount from the tip opening without stagnation, thereby performing the correction work. In this way, when the valve is opened by pressing the valve rod 5 of the applicator during use, an appropriate amount of the homogenized application liquid flows out smoothly and quickly in response to the opening without stagnation, so that the application liquid is The outflow response is extremely good, and the outflow amount can be easily adjusted.

Furthermore, even during use, the coating liquid whose outflow amount is finely adjusted in the gap 7 immediately and smoothly reaches the tip from the chamber 4f in front of the gap 7.
In response to the opening of the valve, a proper amount of liquid flows out smoothly from the tip opening without any stagnation through the valve mechanism, so there is no chance of dripping.

In addition, a gap 7 for adjusting the outflow amount of the coating liquid is spaced rearward from the valve mechanism part of the valve rod 5, and a gap 7 between which the chamber 4
f, the coating liquid near the tip is exposed to outside air and tends to harden, as in the case where the regulating part that adjusts the flow rate of the coating liquid is provided immediately after the valve mechanism part. , it is also possible to avoid the so-called clogging phenomenon.

Further, a bulging portion 5a for forming the gap 7 is located in the chamber 4g immediately behind the gap 7, between the bulging portion 5a and the receiving tube 3a of the packing 3 into which the valve rod 5 is inserted. Since the bulging portion 5a also serves as a spring holder, there is no need to separately form a flange for supporting the front end of the spring body, and the structure is that much simpler. become.
