Further, the inner plug main body 37 is sandwiched and held between the pouring member 38 and the container main body 12.

  Next, a method for assembling the liquid dispensing application container 10 of this embodiment will be described. First, a coil spring 74 is attached to the shaft portion 32 of the inner plug main body 37, and the chip 52 is inserted and set into the cylindrical portion 54 from above the shaft portion 32. Next, the pouring member 38 is placed over the tip 52, the nozzle portion 68 of the tip 52 is inserted into the pouring cylinder portion 46, and the attachment portion 20 of the inner plug main body 37 is fitted into the attachment cylinder portion 40. Push in with the above force. The flange portion 22 of the inner plug body 37 abuts on the inner peripheral surface of the lower end portion of the conical portion 44. At this time, the step portion 22a of the flange portion 22 is locked to the step portion 40a of the mounting tube portion 40, and the inner plug 18 is Made. The inner plug 18 in this state in which the chip 52 is placed in the inner space 72 is attached to the mouth portion 14 of the container body 12.

  Next, the tip 52, the inner plug main body 37, and the dispensing member 38 are attached to the mouth portion 14 of the container main body 12 in which the chemical solution 92 such as a medicine to be applied to the skin is assembled in the above-described state. First, the mounting portion 20 of the inner plug main body 37 is inserted into the mouth portion 14 from the end portion on the bottom portion 28 side. The mounting portion 20 is fluid-tightly fitted to the inner peripheral surface of the mouth portion 14, and the flange portion 22 abuts against the upper end surface of the mouth portion 14 to prevent further insertion. At this time, the engagement protrusion 36 of the mouth portion 14 is fitted and locked in the engagement recess 42 of the dispensing member 38 so that it does not fall off.

  Further, a cap 76 is attached to the mouth portion 14 of the container body 12. The cap 76 is placed over the dispensing cylinder portion 46 of the dispensing member 38 and is rotated around the axis so that the female screw 82 is screwed onto the male screw 16 of the mouth portion 14 and attached. The step portion 45 of the dispensing member 38 is pressed by the large pressure ring 90 of the cap 76 and closed with the inner plug main body 37 sandwiched between the mouth portion 14 of the container main body 12 as shown in FIG. It will be in a sealed state. At this time, the small pressing ring 86 of the cap 76 contacts the stepped portion 47 of the dispensing tube portion 46. Further, the protruding portion 84 of the cap 76 abuts on the tip 68a of the nozzle portion 68 of the tip 52 and is surely pushed to a predetermined length, and the shutoff valve 64 of the tip 52 is pressed against the valve seat portion 34 of the inner plug body 37. The container body 12 is closed in a liquid-tight state. In this state, even if the container main body 12 is tilted, the chemical solution 92 contained in the container main body 12 does not come out, and the metering dispensing application container 10 can be safely transported and stored.

  Next, a method of using the metering dispensing application container 10 will be described. When the chemical solution 98 is taken out from the container body 12 and used, first, the cap 76 is rotated around the axis, and the screwing of the female screw 82 and the male screw 16 of the mouth portion 14 is released and removed. In the process of removing the cap 76, as shown in FIG. 2, when the screwing of the cap 76 and the container body 12 is gradually released and the cap 76 is slightly raised, the tip 52 is also urged by the coil spring 74 and rises. The shut-off valve 64 of the tip 52 is opened slightly apart from the valve seat portion 34 of the inner plug body 37. At this time, the opening 66 a of the through hole 66 of the chip 52 is opened at a position closer to the inner space 72 than the closing projection 48, so that the space inside the container body 12 is separated from the through hole 66 of the chip 52. It communicates with the pouring hole 70 and is in an open state to the outside, so that air permeability inside and outside the container body 12 is ensured. Although the protruding portion 84 of the cap 76 is in contact with the tip 68a of the nozzle portion 68, the ventilation is not blocked because the protruding portion 84 is formed with a groove portion 88 for ventilation. Thereby, even if there is a pressure increase in the container main body 12 due to a temperature difference during storage, the container main body 12 is made equal to the atmospheric pressure by bleeding air when the cap 76 is opened.

  Further, the cap 76 is rotated around the axis to release the screwing. When the cap 76 is removed, the force holding the chip 52 is released, and the chip 52 is pushed up by the coil spring 74 and moves up. Since the cylindrical portion 54 is slidably fitted to the shaft portion 32 of the inner plug main body 37, the tip 52 slides along the axial direction of the shaft portion 32. As shown in FIG. The contact surface 56 reaches the closing protrusion 48 of the extraction member 38, and the tip 52 stops without moving any further. The shutoff valve 64 of the tip 52 is opened widely from the valve seat portion 34 of the inner plug main body 37, the internal space of the container main body 12 communicates with the pouring member 38, and the chemical liquid 92 accommodated in the container main body 12 is poured out. It becomes possible. At this time, the nozzle portion 68 of the tip 52 protrudes outward from the extraction tube portion 46 of the extraction member 38, and the spherical body 69 is exposed. However, since the opening 66a of the through-hole 66 coincides with the closing protrusion 48 of the extraction member 38 and is closed by the insertion port 50 sliding surface 50a of the closing protrusion 48, the drug solution 92 is in a closed state where it is not discharged. is there.

  When the container body 12 is inverted in this closed state, as shown in FIG. 4, the chemical solution 92 in the container body 12 passes through the through hole 30 of the inner plug body 37 and enters the inner space 72 of the dispensing member 38. Fill and fill. Since the through-hole 66 opening 66 a of the tip 52 is blocked by the sliding surface 50 a of the extraction member 38, the chemical liquid 92 in the inner space 72 does not leak out from the nozzle portion 68.

  In the closed state, it is brought close to the surface to be coated such as the skin surface and pressed against the surface to be coated by the tip 68a of the nozzle portion 68 of the chip 52. Then, as shown in FIG. 5, the tip 52 is pushed into the pouring member 38, and the through-hole 66 opening 66 a is located in the inner space 72 away from the closing projection 48, and is opened to fill the inner space 72. The drug solution 92 that has been flowing flows through the through hole 66 to the pouring hole 70 and exits from the tip 68a. Here, the coated surface is lightly tapped with the tip 68a of the nozzle portion 68 of the chip 52, and the chemical solution 92 is poured out from the pouring hole 70 with the momentum when hit. Since the tip 52 is urged outward by the coil spring 74, when it is struck, the coil spring 74 is elastically deformed and the tip 52 is pushed in for a short time, but is immediately restored and closed as shown in FIG. Therefore, the amount of the chemical solution 92 is not excessive. And the chemical | medical solution 92 poured out to the to-be-coated surface is rubbed with the spherical body 69 of the nozzle part 68, and it extends and apply | coats to a desired area.

  After use, the container body 12 is again erected, the cap 76 is attached, the tip 52 is pushed to a predetermined length by the small pressing ring 86 of the cap 76, and the shut-off valve 64 closes the valve seat 34. Liquid-tight and safe storage.

  According to the liquid dispensing application container 10 of this embodiment, with a simple structure, before the chemical liquid 92 of the contents is poured out, the container main body 12 is evacuated so that an appropriate amount of the chemical liquid 92 can be safely used. Can be poured out to a place. In particular, since the chemical liquid 92 is poured out from the pouring hole 70 opened at the center of the tip 68a of the nozzle part 68, if the tip 68a of the nozzle part 68 is applied to the surface to be coated, it is surely pinpointed only at the target site. A predetermined amount can be effectively dispensed to a required position without wasting chemical liquid 92. In addition, while having a liquid stopper mechanism with the inner plug 18 and the tip 52, the structure is such that the air can be easily vented by simply opening the cap 76, and the user does not forget to vent the air and dispenses the chemical 92. Air can be surely vented before. Since the air is sufficiently removed, it is possible to prevent the chemical liquid 92 from being discharged together with the air in the container main body 12 whose pressure has been increased when the chemical liquid 92 is taken out from the container main body 12. Therefore, even if the chemical liquid 92 is highly volatile, the vapor pressure in the container main body 12 can be lowered and can be used safely.

  Furthermore, by making the material of the chip 52 a flexible material such as an elastomer, the adhesion to the inner plug 18 can be enhanced. Further, since the adhesiveness is high, the pressing force of the coil spring 74 can be set low, and the chemical liquid 92 can be dispensed by simply pressing the nozzle portion 68 protruding from the dispensing cylinder portion 46. Since the portion that touches the skin is soft, irritation to the application surface can be reduced. The tip 68a of the nozzle portion 68 that contacts the surface to be coated is provided with a flexible and large spherical body 69 and is easily deformed. When the tip 52 is pushed against the surface to be coated and the chemical solution 92 is poured out, There is little irritation | stimulation to an application surface, a burden is not felt, and a usability | use_condition is favorable. By appropriately adjusting the size of the outer peripheral surface of the spherical body 69, the contact pressure to the coated surface can be changed, and the sliding resistance is adjusted by changing the contact area, and the feeling of use is appropriately changed. Can do. In addition, by forming the spherical body 69 in the nozzle portion 68, it becomes easy for the user to visually recognize, and by checking the nozzle portion 68, the operation of pouring and applying the chemical liquid 92 against the surface to be coated is easy. Can understand.

  Further, a shut-off valve 64 is provided, which can be sealed to the valve seat 34 of the inner plug 18, and when the tip 52 is pushed to a predetermined length, the flow port 25 between the container body 12 and the inner plug 18 is shut off, A stable dispensing amount can be maintained without being affected by the amount of liquid in the container main body 12, and excessive dispensing when the chip 52 is pushed in vigorously can be prevented.
