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]
An application destination that can be flexibly deformed is attached to the front of the opening of the container main body provided with an application agent storage chamber, and a valve seat portion and the valve seat portion are pressed against each other between the application agent storage chamber and the application destination. As a valve applicator formed by arranging a valve mechanism constituted by a valve member biased forward, a valve hole 2 formed in Japanese Utility Model Publication No. 42-13671 is formed with a collar 1a on the upper side and drilled in the center. The valve stem 3 integral with the conical valve seat 3a is protruded to the upper end of the spiral ridge 4 which is locked to the lower inner edge 1b, and the valve seat 3 is fixed to the lower surface of the valve seat 3a. The valve lid 3 receives the outer lid 5 in which the inner lid 1 is pressed into the mouth of the container body 8 and the thick sponge rubber body 7 is bonded to the receptacle 5a from the upper portion 7 '. A liquid container for coating formed by being pierced so as to pass through the central valve hole 6 and inserted into the sponge rubber body, and further cap 10 The idea which makes a summary 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 liquid in the container body flows out from the 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 content liquid is applied to a desired location.

[Problems to be solved by the invention]
By the way, an applicator as 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 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]

[0009]
The effect of this invention is demonstrated with reference to FIG.
Reference numeral 7 denotes a surface to be coated such as a paper surface. The solid thin line at the application site shows the state before being pressed against the surface to be applied, and the thick solid line shows the state where the application site after being pressed against the application surface is deformed and opened (the deformation vertical length of the application site) (Indicated by <dimension Q>). At the time of application, if the application part at the application destination is pressed against the surface to be applied, the application piece of the application part can be bent and deformed, so that it is curved and deformed. At this time, the convex piece portion of the valve member provided between the rows of the application pieces can be bent and deformed, so that it deforms in a curved manner. As described above, the convex piece portion is curved and deformed in accordance with the deformation of the application piece, so that a rough feel in the application operation is reduced.
Furthermore, at this time, the tip body having a wide part slightly protruding from the tip of the coating tip has the highest contact resistance among the coating portions contacting the surface to be coated, and the stress applied to the tip body is relatively large. It will be a thing. At this time, the valve member integrally connected to the tip body is separated from the coating destination valve seat portion toward the rear of the container against the resilience, and the valve opens. (The dimension at the opening is indicated by R.)
When the valve opens, the coating agent in the coating liquid storage chamber passes through the valve, is dispersed in each coating piece of the coating destination coating unit, and flows out to the coated surface.
The influence of the application destination on the backward movement of the tip body when the valve is open is as follows. Since the gap is provided between the back of the wide part of the front body (the back of the front end surface of the front body) and the tip of the application destination application piece, the front body can smoothly move backward without interfering with the application destination. I can do it. In addition, even on the opposite side of the surface to be coated, a gap is provided between the back surface of the wide part of the tip body and the tip of the coating piece in the coating tip row, so that the tip can be applied to the coating tip even if the coating site is curved and deformed. It is possible to move backward smoothly without interfering with.
Also, since the coating piece on the center side of the coating tip row is shortened on the coated surface side, as shown in the figure, the degree of bending of this coating piece is less than the other long coating piece bending of the same row, so the result As a result, the center side of the coating tip row opens more than the left and right sides in the way of opening between the coating pieces. (The difference in opening between the central application piece and the left and right application pieces is indicated by a dimension S.)
As a result, the amount of the coating agent flowing out to the coated surface side can be increased toward the center side and decreased toward the end side, that is, the amount of the coating agent protruding to both sides of the flat coating destination can be suppressed. And by the same effect | action, the coating agent outflow time from a valve to the application | coating part center front-end | tip can be shortened, ie, coating agent discharge quick response property can be improved.
In addition, interference inhibition between the forward movement of the tip and the tip of the coating tip occurs when the coating piece rear bending strength is high, and the coating piece material is soft or has a delicate shape, etc. Since the tip of the coating tip deforms in the other direction (= escapes) while contacting the back surface of the wide front body portion, the gap portion on the back surface of the wide front body portion need not be provided.
At the time of application, the coating agent is dispersed into each coating piece and applied to the surface to be coated. However, since the coating agent is guided more to the recess provided in the center of the tip of the body, the tip contacts the surface to be coated. The area and the other application piece contact area are in the same application amount state.
