Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an applicator having a valve function for applying a liquid or powdery coating agent such as paint, paint, ink, correction liquid, glue, cosmetic liquid, medicine, repair agent, coating agent or the like.
[0002]
[Prior art]
As an applicator with a valve, in which an application destination capable of bending deformation is attached in front of an opening of a container main body provided with an application agent storage chamber, and a valve mechanism is disposed between the application agent storage chamber and the application destination. In Japanese Utility Model Publication No. 42-13671, a valve rod 3 formed with a collar 1a on the upper side and drilled in the center is projected into a valve stem 3 integral with a conical valve seat 3a, and a spiral locked to a lower inner edge 1b. The upper end of the striated body 4 is fixed 3a 'to the lower surface of the valve seat 3a, and the inner lid 1 in which the valve seat is pressed against the valve hole 2 is inserted into the mouth of the container body 8, and the thick wall is formed from the upper part. The outer cover 5 in which the sponge rubber body 7 is bonded to the receiving board 5a is crowned so that the valve rod 3 passes through the valve hole 6 in the center of the receiving board and is inserted into the sponge rubber body, and the cap 10 is further crowned. A device based on a liquid container for application formed as a gist is disclosed.
The usage method of the liquid container for coating agent is as follows.
When the sponge rubber body is pressed down and pressed against the surface to be coated, the valve rod moves inward of the container body as the sponge rubber body is compressed, and the pressure contact between the valve seat and the valve hole is released to create a gap. The internal solution in the container body flows out from this gap and penetrates into the sponge rubber body. Thereafter, the pressing force is released, the valve seat and the valve hole are pressed and sealed, and the sponge rubber body impregnated with the internal solution is applied to a desired location.

[Problems to be solved by the invention]
By the way, the applicator disclosed in the Japanese Utility Model Publication No. 42-13671 is often held by hand, and in this case, the applicator is not perpendicular to the surface to be applied but is inclined at an angle. It is often used with This is because, when the device is used at an oblique angle, the field of view to the coated surface becomes better, and the contact load on the coated surface at the coating destination becomes smaller, which makes it easier to apply.
On the other hand, the applicator as described above is a mechanism that compresses the applicator and opens the valve. Therefore, in order to open and close the valve with a practical force, the tip of the valve stem is at least forward of the middle part of the application destination. It is necessary to be located in
In such an applicator, at the time of application, the tip of the valve rod in the sponge rubber body, which is the application destination, is hard, so that the feel of pushing the valve stem is transmitted, and it becomes a terrible feel and tries to obtain a smooth feel. It is difficult, and when the valve is opened, the valve stem is pushed diagonally backward, and the valve stem moves while contacting other members, so it resists the sum of the urging force against the valve stem and the contact resistance load. As a result, the valve is opened, and the load for opening the valve becomes heavy.
[0004]
An object of the present invention is to provide a valve-equipped applicator that reduces the harsh feel at the time of application and does not increase the load that can open the valve, and that reliably opens the valve even with a small load.
[0005]
