Description

[Detailed Description of the Invention] "Industrial field of application" This invention uses, for example, a coating container containing a liquid such as ink to be used as a writing instrument, or a liquid cosmetic such as liquid lipstick and nail polish to be used as a makeup implement. Application container.

"Prior Art" Conventionally, as this type of coating container, there is known a container body equipped with a coating body such as a brush via a valve mechanism at the tip opening (for example, Japanese Utility Model Publication No. 42-12351). , No. 61-12134). In this conventional coating container, the valve is opened by pressing the tip of the coating body with the coating body facing downward so that liquid such as ink in the container body is sent to the coating body while falling. Is configured.

"Problems to be solved by the device" However, according to the conventional coating container, when the coating body is soft, the pressing force applied to the tip of the coating body is not transmitted to the valve mechanism, and therefore the ink is applied to the coating body. However, there is a drawback in that it is impossible to supply such liquid. Further, when a hard coating is used, there is a drawback that the coating is damaged by the pressing force.

This invention was made in view of the above circumstances,
An object of the present invention is to provide a coating container that can supply a liquid such as ink to an application body even when a soft application body is used, and does not damage the application body even when a hard application body is used. I am trying.

"Means for Solving Problems" This invention relates to a cylindrical container body having a liquid discharge port at its tip, and an applicator attached to the tip of this container body.
A valve rod having a valve body at the tip portion which is movably inserted in the container body in the axial direction thereof and which opens and closes the discharge port; and an operating mechanism for reciprocating the valve rod to open and close the discharge port. A coating container having a structure in which the discharge port is closed by moving the valve rod to the rear end side of the container body, the movable end being movable in the axial direction to the rear end part of the valve rod. A push button having a body integrally provided with the operation mechanism on the peripheral wall of the rear portion of the container body and having a tapered pressing portion on the inner surface, and an abutting portion formed on the moving body and pressed by the pressing portion. When,
And a biasing member for biasing the valve rod toward the rear end side of the container body, and further, the pressing portion and the abutting portion, the moving body is configured to move to the tip side of the container body, Further, a piston member slidably and liquid-tightly provided along the inner wall of the container body is interposed between the valve rod and the moving body.

[Action] When the push button provided on the peripheral wall of the rear portion of the container body is pressed with the applicator facing downward, the action of the pressing portion and the contact portion of the valve rod causes the valve rod to move against the elastic force of the biasing member. Since it is pushed down, the valve body that has closed the discharge port also moves downward to open the discharge port, and the liquid inside the container body is dropped and supplied to the application body from this discharge port. Then, when the pressing operation of the push button is released, the valve rod is pushed upward by the elastic force of the biasing member, so that the valve body closes the discharge port to prevent the liquid from falling.

The discharge port 11 is opened by moving the discharge port 11 in the direction (A in the figure).

Further, a spring (biasing member) 22 is provided inside the shaft portion 13 outside the occlusion body 15, and normally biases the valve rod 17 toward the rear end (direction B in FIG. 1). Therefore, the discharge port 11 is always closed by the valve body 17a, and in this state, the storage chamber 10a is kept liquid-tight.

In addition, the push button 20, the pressing portion 20a, the edge portion (contact portion 18
e) and the spring 22 constitute the operating mechanism 23, respectively. Reference numeral 24 indicates a cap put on the brush brush 14.

Next, the operation and usage of the coating container having the above structure will be described.

First, when the liquid cosmetic R is discharged, the brush brush 14 is directed downward. In this state, the discharge port 11 is closed by the valve body 17a of the valve rod 17 which is biased by the spring 22, and the liquid cosmetic R may be discharged from the inside (storage chamber) 10a of the container body 10 to the brush brush 14. Absent.

Next, when the push button 20 is pressed with a finger, the spring 22
Against the elastic force of (the pressing portion 20a and the edge portion 18e), the valve rod 17 is pushed down, the valve body 17a is also lowered, and the discharge port 11 is opened. Then, the liquid cosmetic material R inside the container body 10 (storage chamber) 10 a falls from the discharge port 11 due to its own weight and the pressurization of the piston 16 that is pushed down integrally with the valve rod 17, and the occlusion body 15 Is once absorbed and supplied to the brush brush 14.

After that, if the pressing operation of the push button 20 is released, the spring 2
2 pushes up the valve rod 17 again and the valve body 17a closes the discharge port 11, so that the excess liquid cosmetic material R does not drop. At this time, the negative pressure generated by the piston 16 that is liquid-tight in the storage chamber 10a of the container body 10 quickly stops the discharge of the liquid cosmetic material R.

According to this embodiment, the discharge port 11 is normally provided with the valve body 17
Since it is securely closed by a, the liquid cosmetic material R is not discharged to the brush brush 14 unless the push button 20 is pressed. Therefore, even if the application container is hung around while carrying, there is no fear of inadvertently ejecting the liquid cosmetic material R. In addition, by operating the push button 20, the brush brush 14
When applying the liquid cosmetic R discharged to, the application container is usually used while holding the pencil and holding the tip end side. At this time, since the push button 20 is provided on the rear portion of the container body 10, it is possible to avoid unnecessary discharge of the liquid cosmetic material R by erroneously pressing the push button 20 with a fingertip or the like. Further, since one-touch operation is possible with one hand, there is an advantage that the other hand can be used freely.

Further, since the piston 16 slides back and forth in the storage chamber 10a of the container body 10 in a liquid-tight manner by operating the push button 20,
When the push button 20 is pressed, the piston 16 can pressurize the liquid cosmetic material R to promote its discharge, and when the push button 20 is stopped, the piston 16 can be pressed.
By the negative pressure of, the discharge of the liquid cosmetic material R can be quickly stopped. Furthermore, the piston 16 can reliably discharge the liquid cosmetic R even when it has a high viscosity. Therefore, the piston 16
As a result, the stability of the discharge of the liquid cosmetic R from this coating container
The certainty can be increased.

If the piston 16 and the moving body 18 are integrally molded, the number of parts can be reduced and the cost can be reduced. Further, the number of the push buttons 20 is not limited to one, and two push buttons 20 may be provided in mutually opposite positions.

[Advantages of the Invention] As described in detail above, according to the present invention, a cylindrical container body having a liquid discharge port at its tip, an applicator attached to the tip of this container body, and a container body A valve rod having a valve body at the tip portion which is movably inserted in the axial direction thereof and which opens and closes the discharge port; and an operating mechanism for reciprocating the valve rod to open and close the discharge port. And, the valve rod is a coating container configured to close the discharge port by moving to the rear end side of the container body, the rear end of the valve rod,
A movable body that is movable in the axial direction is integrally provided, and the operation mechanism is provided on the peripheral wall of the container body, and a push button having a tapered pressing portion on the inner surface is formed on the movable body. The contact part to be pressed and a biasing member for biasing the valve rod toward the rear end side of the container body are provided, and the pressing part and the contact part are provided on the movable body of the container body.

Play.

With the configuration of the valve rod and the operating mechanism for operating the valve rod, the liquid discharge operation inside the container body can be reliably performed, and therefore the reliability thereof can be improved. In addition, when using this coating container, it is usual to hold it with a pencil and hold it with the tip side. At this time, since the push button is provided on the rear part of the container body,
It is possible to avoid unnecessary discharge of liquid due to erroneous pressing of this push button. Furthermore, since the liquid in the container body can be easily and surely delivered to the application body by one-touch operation of the push button, the operability is excellent and the usability is very good. Moreover, when the pressing operation of the push button is released, the ejection port is surely closed, so there is no fear of inadvertently ejecting the liquid when carrying it.

Further, since the piston member slides in a liquid-tight manner along the inner wall of the container main body by the operation of the push button, it is possible to pressurize the liquid when pressing the push button to prompt the discharge of the liquid,
Further, when the pressing operation is stopped, the discharge of the liquid can be quickly stopped by the negative pressure. Furthermore, even when the viscosity of the liquid to be discharged is high, the piston member
This can be reliably discharged. Therefore, it is possible to enhance the stability and reliability of the liquid ejection of the application container.

Further, because of these, it is possible to use a soft or hard application body, respectively, and since the application body is not damaged, it is possible to improve use durability.
