The lower end portion of the holding cylinder portion 96 closes the cap 82 to the container body 12 When this happens, it abuts on the step 45 of the measuring unit 38 formed between the mounting cylinder 40 and the measuring cylinder 44 and holds the measuring unit 38, and the plug 18 between the measuring unit 38 and the container body 12 Hold across.

  Next, a method of assembling the measuring and dispensing application container 10 of this embodiment will be described. First, the nozzle portion 68 of the valve 60 is inserted from the side of the mounting cylinder portion 40 of the measuring unit 38, and the nozzle portion 68 is protruded upward from the insertion port 56 of the closing projection 54. At this time, when a portion slightly thicker than the insertion opening 56 is provided in a part of the valve 60 and a click feeling is given, the valve 60 may be locked and not be removed after the insertion. The application head 76 is attached to the nozzle portion 68 of the valve 60 projecting upward from the insertion port 56 of the measuring device 38. The application head 76 inserts the nozzle 68 into the inner surface 76b from the side opposite to the top surface 76c, and fits the projection 78 of the application head 76 into the locking groove 70 of the nozzle 68, and the outer surface 76a is It is fitted on the outside of the pouring cylinder part 48 and attached. Next, the inside plug 18 is attached to the mounting cylinder 40 of the measuring device 38. The mounting portion 20 of the inside plug 18 is inserted from the end opposite to the bottom portion 28 into the mounting cylindrical portion 40 of the measuring unit 38, and is fitted to the inner peripheral surface of the metering cylindrical portion 44. The flange portion 22 of the inner plug 18 abuts on the lower end portion of the fixed amount cylinder portion 44 to prevent it from being further inserted. At this time, the step 22a of the flange 22 is engaged with the step 40a of the mounting cylinder 40 and does not fall off. At this time, the shaft portion 32 of the inner plug 18 is slidably inserted into the cylindrical portion 62 of the valve 60.

  Next, the inside plug 18, the measuring device 38, the valve 60, and the application head 76 are attached to the mouth 14 of the container body 12 containing the drug solution 98 such as a hair growth agent or a hair growth agent in the above-mentioned state. First, the mounting portion 20 of the plug 18 is inserted into the mouth 14 from the end on the bottom 28 side. The mounting portion 20 is liquid-tightly fitted to the inner peripheral surface of the mouth portion 14, and the flange portion 22 abuts on the upper end surface of the mouth portion 14 to prevent further insertion. At this time, the engagement projection 36 of the opening 14 is fitted and locked in the engagement recess 42 of the measuring unit 38, so that it does not fall off.

  Furthermore, the cap 82 is attached to the opening 14 of the container body 12. The cap 82 is placed over the top surface portion 76c of the application head 76, and is rotated about its axis to screw the female screw 88 into the male screw 16 of the mouth 14 for attachment. The stepped portion 45 of the measuring instrument 38 is pressed by the holding cylinder portion 96 of the cap 82, and is closed in a state in which the inside plug 18 is sandwiched between the inside plug 18 and the opening 14 of the container body 12 as shown in FIG. It becomes. At this time, the valve 60 and the application head 76 are pushed down by the liquid stopper cylinder 90 and descended, and the first valve 64 of the valve 60 is in a pouring state in which the first valve seat 34 of the inner plug 18 is closed. The inside of the container body 12 and the measuring space 46 are shut off. In this state, even if the container main body 12 is inclined, the liquid medicine stored in the container main body 12 does not go out, and the measuring and dispensing application container 10 can be safely transported and stored.

  Next, a method of using the measuring and dispensing application container 10 will be described. When taking out the drug solution 98 from the container main body 12 and using it, first, turn the cap 82 about the axis to release the screwing between the female screw 88 and the male screw 16 of the opening 14 and move the cap 82 in the insertion direction of the valve 60 Then, pull it out almost parallel. At this time, since the valve pull-up hook 92 of the cap 82 is inserted into the locking groove 72 of the valve 60 and locked with a certain level of strength, the valve 60 and the application head 76 slide along with the pulling up of the cap 82 Are pulled up. Since the cylindrical portion 62 of the valve 60 is slidably fitted to the shaft portion 32 of the inner plug 18, it slides along the axial direction of the shaft portion 32. When the second valve 66 of the valve 60 abuts on the second valve seat 58 of the closing projection 54 of the scale 38, the valve 60 does not pull up any more. When the cap 82 is further pulled up, the engagement between the valve lifting hook 92 and the locking groove 72 of the valve 60 is released, and the cap 82 is removed. At this time, as shown in FIG. 2, the second valve 66 of the valve 60 closes the second valve seat 58 of the scale 38, and the first valve 64 opens the first valve seat 34 of the inside plug 18. As a result, the internal space of the container body 12 communicates with the measuring device 38 and is in a measuring state.

  Then, when the container body 12 is inverted in this weighing state, as shown in FIG. 3, the chemical solution 98 in the container body 12 passes through the through hole 30 of the inner plug 18 and flows into the metering space 46 of the metering unit 38. Charge and a fixed amount is measured. In addition, since the second valve 66 of the valve 60 closes the second valve seat portion 58 of the measuring device 38, the chemical solution 98 in the measuring space 46 does not leak out of the nozzle portion 68. In this state, as the partition wall portion 24 of the inner plug 18 approaches the through hole 25, it becomes an inclined surface positioned upward, and the drug solution 98 reliably fills the inside of the measuring space 46. This is because if the partition wall portion 24 is a horizontal surface, an air reservoir will be formed between the partition wall portion 24 and the mounting portion 20 unless the container main body 12 is accurately erected vertically, and the chemical solution 98 is a measuring space. This solves the problem that accurate metering can not be performed without filling in the 46.

  It is brought close to the surface to be coated such as scalp as it is, and pressed on the surface to be coated by the top surface 76 c of the coating head 76. Then, as shown in FIG. 4, the valve 60 is pushed down into the scale 38, and the first valve 64 closes the first valve seat portion 34, and the second valve 66 is separated from the second valve seat portion 58. The through holes 74 of 60 are exposed to the measuring space 46 of the measuring device 38, and the measuring space 46 communicates with the nozzle 68. Then, the drug solution 98 filled in the measuring space 46 flows into the nozzle portion 68 through the through hole 74 and comes out from the tip portion 68 a. At this time, since the first valve 64 closes the first valve seat portion 34, the drug solution 98 in the container body 12 does not flow out, and only the drug solution 98 filled in the measuring space 46 is poured out. The chemical solution 98 in the container body 12 does not come out excessively, and is a fixed amount. However, since the nozzle portion 68 has a small diameter, the chemical solution 98 can not be continuously discharged only by inverting the container. Here, the scalp is lightly tapped with the top surface portion 76c which is the top surface of the application head 76, and the liquid medicine 98 is poured out little by little from the pouring port by the impact when hit. A groove 77 is provided between the top surface 76c, which is the top surface of the application head 76, and the tip 68a of the nozzle 68, and they are not in contact with each other. It does not move to 76 and is dropped directly onto the scalp at a pinpoint from the small diameter nozzle portion 68. Then, the chemical solution 98 dropped uniformly and little by little on the application surface is applied so as to penetrate the scalp while tapping lightly with the application head 76.

  After use, the container body 12 is erected again, the cap 82 is attached, the application head 76 and the valve 60 are pushed by the liquid stopping cylinder 90 of the cap 82, and the first valve 64 closes the first valve seat 34 It is liquid-tight in the pouring state and stored safely.

  According to the metered-out dispensing application container 10 of this embodiment, the flexible and large application head 76 is attached to the tip of the nozzle portion 68 with a simple structure, the application head 76 is applied to the scalp and the valve 60 is pushed to inject the drug solution 98 It can be put out, there is little irritation to the scalp, there is no tactile load, and the feeling of use is good. In addition, a certain amount of the drug solution 98 can be reliably measured and used accurately. By removing the cap 82, the valve 60 can be automatically switched to the weighing state, and the container body 12 is inverted, and then the application head 76 is automatically pressed to the surface to be coated. The switching operation to the ejection state and the pouring operation can be performed at one time, and the process can be performed in a short time with few processes.

  Furthermore, in use, the application head 76 is made of a soft elastomer thin-walled, and the curved portion bends moderately and is easily deformed, and when pressed against the scalp, it can cushion the impact. As it is less irritating, painless and feels good, it can be applied while massaging comfortably. The top surface portion 76c which is the top surface of the application head 76 is provided higher than the tip end portion 68a of the nozzle portion 68, so the nozzle portion 68 made of a hard material does not hit the scalp. Since the groove 77 is provided between the inner surface 76 b of the application head 76 and the outer peripheral surface of the nozzle 68 of the valve 60, the chemical liquid 98 poured out from the nozzle 68 is not transmitted to the application head 76. Because it drips on the scalp vertically, it is possible to aim at the position to be applied precisely.

  In addition, the lower end of the outer surface 76a of the application head 76 is fitted from the outside to the dispensing cylinder 48 of the measuring unit 38, and the length overlapping the upper end of the dispensing cylinder 48 even in the weighing state where the valve 60 is raised. Therefore, no gap is formed between the application head and the dispensing cylinder, and foreign matter is not caught. Furthermore, the application head 76 is securely attached with the engagement projection 78 fitted in the engagement groove 70 of the nozzle portion 68 and does not come off. Only by moving the container body 12 and tapping lightly, the application head 76 is The chemical solution 98 can be uniformly applied at 76. An application projection 80 is provided on the top surface portion 76c of the application head 76, and the massage effect is enhanced when the scalp is lightly tapped with the top surface portion 76c, and the feel is also improved. Further, the cap 82 can be provided with a liquid stop cylinder 90 fitted with the groove 77 and a valve pull-up hook 92 so that transportation and storage can be performed in a reliable liquid tight state, and the cap 82 can be removed The valve 60 can be reliably pulled up to the weighing state, the structure is simple and the operation process of pouring out is simple and easy to use.
