Description

[Detailed description of the invention] [Industrial field of application] This invention is applicable to, for example, a coating container used as a writing instrument filled with a liquid such as ink, or a liquid lipstick.
The present invention relates to an applicator container used as a cosmetic tool containing liquid cosmetics such as nail polish.

[Conventional technology]

Conventionally, as this type of applicator container, one is known in which an applicator such as a brush is attached to the opening of the container body via a valve mechanism (for example, in the Utility Model Act published in 1973).
No. 12351, Jitko No. 61-12134). This conventional coating container is configured such that a valve is opened by pressing the tip of the coating body, and liquid such as ink inside the container body is sent to the coating body.

[Problem that the invention attempts to solve]

By the way, in the case of the above-mentioned conventional application container, if the application body is soft, the pressing force applied to the tip of the application body is not transmitted to the valve mechanism, and therefore liquid such as ink is supplied to the application body. However, when a hard coated body is used, the coated body is damaged by the pressing force.

This invention was made in view of the above circumstances, and it is possible to supply liquid such as ink to the coating body even when a soft coating body is used, and even when a hard coating body is used. The purpose of the present invention is to provide a coating container that does not damage the coating material.

[Means for solving the problem] This invention consists of a container body filled with a liquid inside, a cylindrical housing attached to the tip of the container body, and a cylindrical housing attached to the housing or the container body, a valve seat body having a hole communicating from the container body to the housing; a cylindrical piston fluid-tightly and slidably attached to the inner wall of the housing on the distal side of the valve seat body; and a cylindrical piston that is in contact with the rear end of the piston. a valve stem which is arranged to extend rearward inside the housing, and whose swollen valve portion normally closes a hole in the valve seat body and opens the hole when moved rearward; a biasing member that biases the valve portion of the valve stem toward the hole of the valve seat body; and a cylinder that is fitted and fixed to the distal end side of the piston and has a tapered sliding portion formed on its outer periphery. a shaped tip shaft, and an annular rib that is fitted and fixed to the outer periphery of the housing and is arranged to cover the outer periphery of the tip shaft, and is slidable on the sliding portion of the tip shaft inside the tip portion. The holder includes a cylindrical holder in which a notch extending rearward from the tip edge is formed in the distal end, and an applicator whose proximal end is fixed inside the distal end of the tip shaft.

[Effect]

When you press the outer periphery of the tip of the holder inward with the applicator facing downward, the inner diameter of the annular rib formed at the tip of the holder will shrink, and the tapered sliding part of the tip will slide backward inside the annular rib. do. As the front shaft slides, the piston and valve stem move rearward.
Then, the valve part of the valve stem, which had been blocking the hole in the valve seat body, moves away from the hole, and the movement of the piston compresses the inside of the housing and the container body, resulting in high pressure, which is stored inside the container body. The liquid flows into the housing through the hole in the valve seat body and flows out through the hole in the piston to the applicator body.

When you stop pressing the holder part, the valve stem returns to its original position by the biasing member, and the valve part of the valve stem comes into contact with the hole in the valve seat body in a biased state, causing the hole to close. do. Additionally, the pressure within the housing and within the container body decreases as the piston returns to its original position. This stops the liquid from flowing out to the application body.

In addition, in the figure, C is a cap that covers the applicator 11, and is detachably attached to the housing 4. Further, L is a liquid such as ink stored in the container body 2.

In the application container 1 having the above structure, when the application body 11 is directed downward and the uneven portion 10c of the holder 10 is pressed inward, the inner diameter of the annular rib 10a formed at the tip of the holder 10 is reduced, and the inner diameter of the annular rib 10a formed on the tip shaft 9 is reduced. A tapered sliding portion 9a slides rearward within the annular rib 10a. As the front shaft 9 slides, the piston 6 slides rearward inside the housing 4, and the valve rod 7 in contact with the inner cylinder 6d of the piston 6 also moves rearward. Then, the valve portion 7b that has until now closed the hole 3a of the valve seat body 3 separates from the valve seat 3b, and the liquid L in the container body 2 flows into the housing 4 through the hole 3a. At the same time, the storage body 5 is compressed by the piston 6, and the liquid L that has been absorbed
is discharged into the housing 4. Furthermore, the inside of the housing 4 and the inside of the container body 2 are compressed by the movement of the piston 6 and become high pressure. As described above, the liquid L flowing into or being discharged into the housing 4 passes through the groove 6c of the inner cylinder 6d, passes through the inside of the piston 6, and flows out to the applicator 11.

When you stop pressing the holder 10, the valve stem 7, piston 6, and front shaft 9 return to their original positions due to the biasing member 8 and the occluding body 5, and the valve portion 7b contacts the valve seat 3b and opens the hole 3a again. Obstruction. Further, as the piston 6 moves, the pressure inside the housing 4 and the container body 2 decreases, and the storage body 5 expands to absorb the excess liquid L inside the housing 4. With the above, the outflow of the liquid L to the application body 11 is stopped.

According to the coating container 1 having the above configuration, the liquid L in the container body 2 can be supplied to the coating body 11 by pressing the uneven portion 10a of the holder 10 inward. Therefore, since it is not necessary to apply a pressing force to the applicator 11, a soft brush or the like can be used as the applicator 11. Further, even if a hard coating body 11 is used, the coating body will not be damaged by the pressing force. Further, since the interior of the housing 4 and the container body 2 is compressed by the piston 6 and becomes high pressure, the liquid L can flow out to the applicator 11 well. Furthermore, after the liquid L flows out, the pressure inside the housing 4 and the container body 2 becomes low, and the liquid L inside the housing 4 is absorbed by the storage body 5, so that excess liquid L is prevented from flowing out. be able to.
