[0023]
Next, a method for using the quantitative dispensing container 10 of this embodiment will be described. The container body 12 is filled with a chemical solution such as a hair-growing agent or a hair nourishing agent, or a cosmetic solution, and the inner plug 18 to which the valve member 40 and the measuring cylinder member 36 are attached in advance is attached to the outlet 14 of the container body 12. At this time, the shaft portion 30 of the inner plug 18 is fitted into the cylindrical portion 42 of the valve member 40. The large-diameter extraction nozzle portion 48 of the valve member 40 is inserted into the insertion port 38 of the measuring cylinder member 36, and the small-diameter extraction nozzle portion 50 protrudes outside the measuring cylinder member 36.
[0024]
Further, a cap 56 is attached to the outlet 14 of the container body 12. When the engaged portion 58 of the cap 56 is pressed against the small-diameter dispensing nozzle portion 50 of the valve member 40, the engaged portion 58 of the cap 56 is slightly elastically deformed and opened outward. The bulging portion 62 gets over the engaging portion 54 of the small-diameter dispensing nozzle portion 50 and the elastic deformation returns to the original, and the bulging portion 62 is positioned below the engaging portion 54. At this time, while the fitting projection 64 of the cap 56 is fitted to the spout 51 of the valve member 40, the valve member 40 is moved toward the inside of the measuring cylinder member 36, and the valve member 40 is moved as shown in FIG. The first valve 44 closes the through hole 26 of the inner plug 18 and comes into close contact with the step portion 34, so that the chemical solution in the container body 12 does not flow out.
[0025]
Next, when taking out and using a chemical | medical solution from the container main body 12, if the cap 56 is removed first, it will be extracted from the small diameter extraction nozzle part 50 of the valve member 40. FIG. That is, since the engaging portion 54 of the small-diameter dispensing nozzle portion 50 is engaged with the bulging portion 62 of the engaged portion 58 of the cap 56, the valve member 40 moves along with the movement of the cap 56. It moves toward the outside of 36. In the valve member 40, the second valve 46 closes the insertion port 38 of the measuring cylinder member 36 and is in close contact with the stepped portion 39, and the first valve 44 is separated from the stepped portion 34 of the inner plug 18 and inside the container body 12. It becomes a measurement state. When the cap 56 is further pulled away, the engaged portion 58 of the cap 56 is elastically deformed and opened outward, the bulging portion 62 is detached from the engaging portion 54 of the small diameter dispensing nozzle portion 50, and the cap 56 is removed.
[0026]
Then, when the container body 12 is turned upside down in this measuring state, as shown in FIG. 2, the chemical solution in the container body 12 passes through the through hole 26 of the inner plug 18 and flows into the measuring cylinder member 36 to be filled. A certain amount is weighed. Since the second valve 46 closes the insertion port 38 of the measuring cylinder member 36, the chemical solution in the measuring cylinder member 36 does not leak outside. In this state, the upper surface 32a of the guide protrusion 32 is obliquely expanded downward with respect to the through hole 26, so that the liquid medicine is reliably filled in the measuring tube member 36. This is because if the upper surface 32a is a horizontal surface, an air pocket is formed between the upper surface 32a and the side wall of the measuring cylinder member 36 unless the container body 12 is accurately turned upside down and directed vertically. This solves the problem that the measuring tube member 36 is not filled with the chemical solution and accurate measurement cannot be performed.
[0027]
In this state, as shown in FIG. 4, the head 70 is moved closer to the head 70 and pushed by the tip of the small-diameter dispensing nozzle 50 of the valve member 40. Then, as shown in FIG. 3, the small-diameter dispensing nozzle portion 50 is pushed down into the measuring tube member 36, and the valve member 40 moves toward the inside of the measuring tube member 36. The first valve 44 closes the through hole 26 of the inner plug 18 and is in close contact with the step portion 34, the second valve 46 is separated from the insertion hole 38 of the measuring tube member 36, and the through hole 52 of the valve member 40 is formed of the measuring tube. It is exposed to the inside of the member 36 so that the spout 51 can be opened and can be poured. And the chemical | medical solution with which the inside of the measurement cylinder member 36 was filled passes the through-hole 52, flows through the spout 51 of the large diameter pouring nozzle part 48 and the small diameter pouring nozzle part 50, and comes out outside. At this time, since the first valve 44 closes the through hole 26 of the inner plug 18, the chemical solution in the container main body 12 does not flow out, and the chemical solution in the container main body 12 does not come out excessively, and the amount is constant. And the chemical | medical solution sprinkled on the head 70 is imprinted on a scalp suitably with a hand.
[0028]
After use, the cap 56 is attached to the container body 12 again, and the first valve 44 of the valve member 40 is stored safely in a metered state in which the through hole 26 of the inner plug 18 is closed.
[0029]
The fixed-quantity dispensing container 10 of this embodiment can measure a certain amount of chemical liquid reliably and use it accurately with a simple structure and simple operation. Further, by removing the cap 56, the valve member 40 can be automatically switched to the metering state. By simply turning the container body 12 upside down and pressing the small-diameter dispensing nozzle portion 50 against the head 70, the valve member 40 is automatically The switching of the valve member 40 to the metering and dispensing state and the dispensing can be performed at a time, and there are few work processes and the coating can be performed in a short time.
[0030]
Note that the quantitative dispensing container of this embodiment is not limited to the above-described embodiment, and the material, shape, shape of each member, etc. can be freely changed. The shape of the engaging portion that locks the cap and the valve member may be any shape that can be reliably locked with an appropriate force. Further, the shapes of the shaft portion of the inner plug and the cylindrical portion of the valve member are not limited to the above-described embodiment, and any shape can be used as long as the valve member is reliably moved in a certain direction without rattling. Further, the application is not limited to the above embodiment as long as it contains chemicals, cosmetics, and other liquids and can be taken out quantitatively.
[0031]
