[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a liquid application container.

[0002]

2. Description of the Related Art There is known a container in which a water-permeable rubbing member is fitted to an opening of a container body having an elastically squeezable body, and the rubbing member is applied in an inverted state of the container body. Have been. 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.

[0003]

In recent years, there has been a medicinal coating liquid in which the amount of application is determined once and per day. Containers are not suitable due to the uncertainty of their use.

[0004] In the present invention, the usage amount per one or one day can be measured in advance, and the coating container which can be measured in such a manner can be obtained by measuring the liquid level in the container body at the temperature of the hand holding the container. Since the measurement may not be possible due to the rise in the temperature of the air above and expansion, such a disadvantage is removed. Is not incomplete.

[0005]

A holding cylinder 6 is erected from an elastically squeezable container body 1 for erecting the mouth and neck 3 and a first mounting cylinder 5 fitted to the mouth and neck. Along with
A tubular member 4 for erecting a pipe fitting tube 8 from an inner periphery of an inward flanged wall 7 attached to a lower portion of the holding tube to form a measuring chamber 9 between the tube and the holding tube; The nozzle 11 that raises the tapered cylindrical wall 13 upward and inward from the second mounting cylinder 12 fitted to the portion, and the coil spring 18 from the fixed cylinder 17 fitted to the upper inner surface of the holding cylinder 6 At the upper end of the spring, a horizontal plate portion 19 is provided at the upper end of the spring, which is pressed against the inner surface of the tapered cylindrical wall in a water-tight manner, and is inserted from the center of the horizontal plate portion into a spout 14 formed at the upper end of the nozzle. The rod 20 is erected, and a stoppered member 16 having a large-diameter portion 21 attached to the upper end of the stopper rod, and a liquid outflow pipe 26 vertically extending from the pipe fitting tube 8 to the bottom of the container body.
And a flow path 23 between the outer surface of the stopper rod and the periphery of the spout.
The upper end surface of the nozzle can be closed watertightly on the lower surface of the large-diameter portion 21 by pressing down against the bias of the coil spring 18.

[0006]

When the cap 27 is removed from the state shown in FIG. 1 and the body of the container is squeezed from this state, the liquid in the container fills the measuring chamber 9, and when the body is released, the excess liquid that has entered the upper part of the measuring chamber is obtained. Is sucked back into the container 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 part 21 is located at the upper end of the nozzle 11 (FIG. 2).
In this case, the check valve 22 formed by the inner surface of the tapered cylindrical wall 13 and the outer surface of the horizontal plate portion 19 opens, and the coating liquid flows out through the valve and the flow path 23. When the pressure in the state of FIG. 2 is further pressed as shown in FIG. When the large-diameter portion 21 is separated from the surface to be coated, the horizontal plate portion 19 rises and the check valve 22 closes again.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 denotes a container body, and a mouth and neck 3 is erected from an upper end of an elastically deformable body 2 via a shoulder.

Reference numeral 4 denotes a transparent tubular member, which holds the holding tube 6 from the first mounting tube 5 screwed to the upper end of the mouth and neck.
An inward flange-like wall 7 is attached to the lower part of the holding tube, and a pipe fitting tube 8 stands upright from the inner peripheral edge of the wall. The cylinder forms a measuring chamber 9 with the holding cylinder 6.

Reference numeral 11 denotes a nozzle having a second mounting cylinder 12 fitted to the upper end of the holding cylinder 6. The nozzle is tapered upward and inward from the second mounting cylinder 12 provided in a double cylindrical shape. The tubular wall 13 stands upright. The upper end of the cylindrical wall is formed by a spout formed by the upper end.
It is preferable that the liquid discharged from 14 be bent downward and inward in a reverse tape shape so as to improve the drainage.

Reference numeral 16 denotes a member with a plug, which projects a coil spring 18 upward and inward from a fixed cylinder 17 fitted to the upper inner surface of the holding cylinder 6 described above, and a horizontal plate 19 to the upper end of the spring. And a stopper 20 is erected by being inserted from the center of the horizontal plate portion 19 into a spout 14 formed by the upper end of the nozzle, and a large-diameter portion 21 is attached to the upper end of the stopper rod. The outer edge of the horizontal plate 19 is tapered.
The discharge valve 22 is formed by being pressed against the inner surface of the cylindrical wall 13 in a watertight manner, and the large-diameter portion 21 is pressed down on the upper surface against the bias of the coil spring 18 to plug the inside of the spout 14. The rod 20 descends,
The lower surface of the large-diameter portion 21 is provided so as to be in water-tight contact with the upper end surface of the nozzle. Although a groove is provided vertically on the outer surface of the stopper rod 20 to form the channel 23, the groove may be provided on the periphery of the spout. For convenience in molding, the stopper rod 20 may be formed in a cylindrical shape, and a separately molded core member 24 having a large diameter portion may be fitted into the cylindrical hole.

A liquid outflow pipe 26 extends vertically from the pipe fitting tube 8 to the bottom of the container.

Reference numeral 27 denotes a cap provided as needed.

[0013]

[Effect of the Invention] The present invention has the above-described configuration, and the measuring chamber 9 is provided.
Is provided so as to apply the liquid measured in the measuring chamber, so that the application amount is insufficient and the effect is insufficient, and the application liquid is not wasted due to too much. Further, a discharge valve 22 was formed by pressing a horizontal plate portion 19 attached to an upper end of a coil spring 18 rising from the holding cylinder 6 into a tapered cylindrical wall 13 of the nozzle 11 fitted to the upper end of the holding cylinder 6. Therefore, the discharge valve will not open unless the large-diameter portion 21 at the upper end of the plug rod rising from the horizontal plate portion through the spout 14 is pushed down, so that the air inside the container is heated at the temperature of the hand holding the container body. Expands and pressurizes the liquid surface, and even if the liquid in the container tries to flow into the measuring chamber side by the pressurization, the flowing liquid increases the air pressure on the measuring chamber side, so that the inflow becomes impossible. As described above, the measured liquid does not increase due to the expansion of the air in the container. Further, a large diameter portion 21 is provided at the upper end of the plug rod 20 which rises from the horizontal plate portion 19 through the spout 14, so that the lower surface of the large diameter portion 21 closes the upper end surface of the nozzle when the large diameter portion is pushed down. Therefore, since the flow path 23 is provided between the outer surface of the tapping rod and the periphery of the spout, the flow path is opened only at an intermediate position where the tapping rod 20 moves up and down by the discharge valve 22 and the large diameter portion 21. This makes it extremely easy to adjust the opening time of the flow passage, so that even if the air in the container is increased in pressure as described above, it is possible to prevent the coating liquid from flowing out too much.
