[Problems to be solved by the device]

 Some of the recent medicinal coating liquids have a fixed coating amount per day, but as a container to store such coating liquid, the conventional container is not clear in its usage amount. Not suitable because there is.

The present invention is designed such that the amount used once or daily can be measured in advance, and such a coating container that can be measured is a liquid surface inside the container at the temperature of the hand holding the container. Since the temperature of the upper air rises and the metering may become impossible due to expansion, this drawback is eliminated.Furthermore, the high pressure inside the container due to the above-mentioned air expansion causes the liquid to squirt during the application. This is to prevent incomplete coating.

[0005]

[Means for Solving the Problems]

 An elastically squeezable container body 1 that erects the mouth / neck portion 4, and a seat plate 11 fixed to the upper end of the mouth / neck portion at the upper end opening surface of the mouth / neck portion 4 is watertightly closed, and A pipe 15 communicating with the bored through hole 13 is hung vertically to the bottom of the container, and an inner cylinder 16 is surrounded by the through hole 13 and an outer cylinder 17 is surrounded by the inner cylinder. A mouth closing member 10 that stands upright with a metering 18 provided therebetween, and a holding cylinder 23 that is watertightly contacted from the upper end of the peripheral wall 21 screwed to the outer surface of the mouth and neck to the outer surface of the outer cylinder 17 so as to be vertically movable. Standing up, the outer peripheral portion is fixed to the inner surface of the holding cylinder, the central portion of the horizontal plate 27 with the through hole 26 is detachably fitted to the inner surface of the inner cylinder 16, and the plug 28 is hung down. 27 When the operating cylinder 20 having a flange 37 attached to the inner surface of the upper holding cylinder 23 and the lower end of the peripheral wall 34 hanging from the outer periphery of the top plate 33 with the small through holes 32 are fixed to the upper end of the holding cylinder 23. Both Then, the stopper rod 36 hanging down from the central portion of the top plate 33 is inserted into the flange hole of the flange 29 so as to be pushed down, and the upper surface of the large outer diameter portion 35 attached to the lower end of the stopper rod is guided to the inner peripheral portion of the flange 29. An elastic coating member 31 which is pressed against each other to form a check valve. A stopper rod lowering gap is provided between the lower end surface of the stopper rod 36 and the central portion of the horizontal plate 27, and the flange 29 and the top plate 33 are provided.

[0006]

[Action]

 The cap 40 is removed from the state shown in FIG. 1, and as shown in FIG. 2, the operating cylinder 20 is screwed up so that the plug 28 also rises and the inner cylinder 16 opens. By elastically squeezing the container body 2 from this state, the coating liquid in the container body fills the measuring chamber 18, and when the body part is released, the excess liquid is sucked back into the container and measured. When the container body is inverted from the measuring state and the top plate 33 of the elastic coating member 31 is pressed against the surface to be coated, the top plate and the peripheral wall 34 are elastically deformed, and the large outer diameter portion 35 separates from the flange 29 and is non-returned. When the valve opens, the coating liquid that had moved to the inward flange side due to the above inversion enters the liquid storage chamber 37 between the flange 29 and the top plate 33, and further the small through hole of the top plate. It passes through 32 and adheres to the coated surface. The check valve is always closed unless the top plate 33 is pushed down. Therefore, in the metering state shown in FIG. 2, the air inside the container expands and pressurizes the liquid surface at the temperature of the hand holding the container, Even if the liquid inside the container tries to rise above the mouth closing member 10 having the measuring chamber 28 through the pipe 15, the air inside the holding cylinder 23 below the check valve will be pressurized due to the rise of the liquid, and No liquid will enter the space.

[Effect of the device]

 The present invention has the configuration described above, and since the measuring chamber 18 is provided to apply the liquid measured in the measuring chamber, the coating amount is insufficient or too large, and the effect of the coating liquid is insufficient. There is no such a case, and since a check valve that is normally closed unless the top plate 33 of the coating member 31 is pushed down is provided above the measuring chamber 18, the coating liquid in the container body is pushed above the mouth portion closing member 10. When it is raised, the space between the check valve and the mouth closing member 10 is also pressurized by the inflowing liquid, so that the air inside the container expands due to the temperature of the hand holding the container and the liquid level rises. Even if the pressure is applied, the stored liquid does not enter the measuring chamber with this amount of pressure, that is, there is no excessive measurement, and since the liquid storage chamber 37 is provided between the flange 29 and the top plate 33. , The container is turned upside down and the top plate 33 is pressed against the surface to be coated, so that even if the check valve opens, it will pass through the valve. The coating liquid enters the liquid reservoir chamber at the same pressure as the outside air due to the formation of the small through hole 32, and then is applied through the small through hole 32, so that the air inside the container becomes high pressure as described above. Even if the check valve is opened in this state, the coating solution will not spout from the small through hole.
