[Industrial applications]

 The present invention relates to a liquid application container.

[0002]

[Prior Art]

 BACKGROUND ART There is known a container in which a rubbing member having water permeability is fitted into a mouth of a container body having an elastically squeezable body, and application is performed by the rubbing member in an inverted state of the container body. There is also known a container in which the rubbing member is a rollable sphere, and the sphere is rolled along the surface to be coated so that the liquid attached to the sphere adheres to the surface to be coated.

[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]

 A container body 1 having an elastically squeezable body portion that erects the mouth and neck portion 3, and a holding cylinder 6 that erects from the first mounting cylinder 5 that is fitted to the mouth and neck portion, and is attached to the lower portion of the holding cylinder. The pipe fitting cylinder 8 is erected from the inner circumference of the inward flange-shaped wall 7 to form a measuring chamber 9 between the cylinder and the holding cylinder, and the upper end of the holding cylinder 6 is fitted. The coil spring 18 is projected upward from the nozzle 11 that erects the taper-shaped cylindrical wall 13 upward from the second mounting cylinder 12 and the fixed cylinder 17 that is fitted to the upper inner surface of the holding cylinder 6. At the upper end of the spring, a horizontal plate portion 19 that is watertightly pressed against the inner surface of the taper-shaped cylindrical wall is attached, and the plug rod 20 is erected from the center of the horizontal plate portion through the spout 14 formed by the upper end of the nozzle. Then, the member with a plug 16 having the large diameter portion 21 attached to the upper end of the plug rod, and the liquid outflow member hung from the pipe fitting cylinder 8 to the bottom of the container body. 26, which is provided with a flow path 23 between the outer surface of the plug rod and the periphery of the spout, and is pushed down against the bias of the coil spring 18 so that the lower surface of the large diameter portion 21 serves to secure the upper end surface of the nozzle. It was formed so that it could be closed in a watertight manner.

[0006]

[Action]

 When the cap 27 is removed from the state of FIG. 1 and the body of the container is squeezed from this state, the liquid inside the container fills the inside of the measuring chamber 9, and when the body is released, the excess liquid that has entered above the measuring chamber is a container. It is sucked back into the body and the measurement is completed. When the container body is inverted from this state and the upper surface of the large diameter portion 21 is lightly pressed against the surface to be coated, the stopper rod 20 slides against the bias of the coil spring 18 as shown in FIG. The portion 21 approaches the upper end (lower end in FIG. 2) of the nozzle 11, and at this time, the check valve 22 formed by the inner surface of the taper-shaped tubular wall 13 and the outer surface of the lateral plate portion 19 is opened, so that the valve and the flow path are formed. The coating liquid flows out through 23. When it is further strongly pressed as shown in FIG. 3 from the state of FIG. 2, the lower surface of the large diameter portion 21 and the upper end surface of the nozzle 11 are in watertight contact with each other to stop the outflow. When the large-diameter portion 21 is separated from the surface to be coated, the lateral plate portion 19 is raised and the check valve 22 is closed again.

[Effect of the device]

 The present invention is configured as described above. Since the measuring chamber 9 is provided to apply the liquid measured in the measuring chamber, the coating amount is insufficient and the effect is insufficient, or the coating amount is large. The liquid is not wasted. Further, the discharge valve 22 is formed by pressing the horizontal plate portion 19 attached to the upper end of the coil spring 18 rising from the holding cylinder 6 into the taper-shaped cylindrical wall 13 of the nozzle 11 fitted to the upper end of the holding cylinder 6. Therefore, the discharge valve does not open unless the large-diameter portion 21 at the upper end of the stopper rod rising from the lateral plate portion through the spout 14 is pushed down. Expands and pressurizes the liquid surface, and even if the liquid in the container tries to flow into the measuring chamber side due to the pressurization, the inflowing liquid increases the air pressure on the measuring chamber side, so that the inflow becomes impossible, and therefore Unlike the conventional case, the measured liquid does not increase due to air expansion in the container body. Further, a large diameter portion 21 is attached to the upper end of the stopper rod 20 standing upright from the lateral plate portion 19 through the spout 14, and the lower surface of the large diameter portion 21 is closed when the large diameter portion is pressed down. Since there is a flow passage 23 between the outer surface of the plug rod and the periphery of the spout, the flow passage is formed by the discharge valve 22 and the large diameter portion 21 only at an intermediate position where the plug rod 20 moves up and down. As a result, the flow path opening time can be adjusted very easily, and even if the air inside the container has a high pressure as described above, it is possible to prevent the coating solution from flowing out too much.
