(First embodiment)
The liquid application tool of this embodiment is configured as shown in FIGS. 1 and 2, FIG. 1 is a cross-sectional view of the liquid application tool, and FIG. 2 is a cross-sectional view showing a usage state of the liquid application tool. The liquid application tool 1 has a container body 10 and a cap 20, and the cap 20 can be attached to and detached from the container body 10. Discharge portion 30 for discharging the liquid is provided in the container body 10, configured to coating by ejecting liquid reserved in the container body 10 from the discharge unit 30.

  The container body 10 is molded from a synthetic resin, and a container cover 11 is attached to the container opening 10a. The container cover 11 is covered with an application base 12, and a brush 13 is embedded in the application base 12. A cap 20 is detachably attached to the container cover 11.

  The discharge unit 30 includes a pump 31, a discharge nozzle 32, and a flexible tube 33. The pump 31 includes a cylinder 31 a, a piston 31 b, and a piston rod 31 c. The pump 31 is assembled to the container cover 11 and the pump housing 34. The pump housing 34 is assembled to the container cover 11.

  A piston 31b is slidably assembled to the cylinder 31a, and a plate 31d is fixed to a piston rod 31c assembled to the piston 31b. A discharge nozzle 32 is fixed to the tip of the plate 31d, and a spring 31e is provided between the plate 31d and the cylinder 31a. The spring 31e constantly urges the discharge nozzle 32 in the discharge direction.

  A liquid passage 31b1 is formed in the piston 31b, and the liquid passage 31b1 is opened and closed by an on-off valve 31f. A discharge passage 32a is formed in the discharge nozzle 32, and liquid is supplied from the pump chamber 38 to the discharge passage 32a by the operation of the pump 31 through the passage 31d1 formed in the plate 31d.

  A flexible tube 33 is connected to the cylinder 31a, and a liquid discharge check valve 35 is provided inside the cylinder 31a at a connecting portion of the flexible tube 33. The flexible tube 33 is formed of resin or rubber and has a weight 36 on the liquid suction port side, and the weight of the weight 36 can always guide the liquid suction port 33a into the liquid according to the use state. . The flexible tube 33 is formed of resin. Examples of the resin material include thermoplastic resins such as polyolefin resin, polystyrene resin, polyvinyl chloride resin, polyvinylidene chloride, polyvinyl alcohol resin, polyacrylonitrile resin, polyacrylic acid resin, gen resin, and polyamide. Resin, polyester resin, polycarbonate, polyacetal, fluorine resin, polyurethane resin and the like. Examples of the polyolefin resin include polyethylene, polypropylene, 4-methylpentene-1, polybutene-1, and linear low density polyethylene. Examples of the polyvinyl alcohol resin include ethylene-vinyl alcohol copolymer, ethylene-vinyl acetate copolymer, and syndiotactic polyvinyl alcohol. Examples of the gen-based resin include polybutadiene, polyisoprene, and cyclized gen. The flexible tube 33 is formed to be bendable by a pipe or a bellows.

  The pump housing 34 is provided with a check valve 40 for introducing outside air. This check valve 40 for introducing outside air is composed of a valve body 40a and a weight 40b. The valve body 40a is movably provided in a hole 34a formed in the pump housing 34, and a weight 40b fixed to the valve body 40a is a container body. 10, the valve portion 40 a 1 of the valve body 40 a is located outside the container body 10. A communication hole 40a2 is formed in the valve body 40a, and the communication hole 40a2 communicates the inside of the container body 10 and the external communication path 11a formed in the container cover 11 so that the outside air can be introduced into the container body 10 in an upright state. The inflow is not blocked, the inflow of outside air into the container body 10 is blocked in the inverted state, and the outside air is flowed into the container body 10 when the inside of the container body 10 becomes negative pressure.

  Next, use of the liquid application tool 1 of this embodiment will be described with reference to FIG. 2A shows an upright state before use, and FIG. 2B shows an inverted state during use. When the liquid applicator 1 is not used, the cap 20 is closed as shown in FIG. 1, the tip of the discharge nozzle 32 is in close contact with the inner wall of the cap 20, and the pump 31 does not operate. The liquid inside does not discharge. In this upright state, as shown in FIG. 2A, the outside air introduction check valve 40 has a communication hole 40 a 2 of the valve body 40 a that passes through the external communication path 11 a formed in the container body 10 and the container cover 11. It communicates and does not block the flow of outside air into the container body 10.

  The cap 20 is removed at the time of use such as applying a hair-growing agent or hairdressing agent to the head, and the tip of the discharge nozzle 32 is applied to the head 100 in an inverted state as shown in FIG. 32 is pushed up and moves against the spring 31e. Due to the movement of the discharge nozzle 32, the piston 31b slides through the piston rod 31c, and pressure is applied to the liquid accumulated in the pump chamber 38 of the cylinder 31a, whereby the liquid discharge check valve 35 is closed and the pump chamber 38 is closed. The pressure of the accumulated liquid rises and the on-off valve 31f opens. As a result, the liquid in the pump chamber 38 passes through the liquid passage 31b1 of the piston 31b, is guided from the passage 31d1 to the discharge passage 32a of the discharge nozzle 32, and is discharged.

  When the application of the tip of the discharge nozzle 32 to the head 100 is stopped, the discharge nozzle 32 is moved in the discharge direction by the spring 31e, and in conjunction with this, the piston 31b is moved through the piston rod 31c, and the open / close valve 31f Closes. As a result, the pressure in the pump chamber 38 of the cylinder 31a is reduced to a negative pressure, and the liquid discharge check valve 35 is opened, and the liquid in the container body 10 enters the pump chamber 38 of the cylinder 31a via the flexible tube 33. Inhaled. Again, by applying the tip of the discharge nozzle 32 to the head 100, the discharge nozzle 32 is similarly moved by being pushed up, and pressure is applied to the liquid accumulated in the pump chamber 38 of the cylinder 31a, thereby causing a check valve for liquid discharge. 35 closes and the pressure of the liquid accumulated in the pump chamber 38 rises, and the liquid in the pump chamber 38 passes through the liquid passage 31b1 of the piston 31b and is led from the passage 31d1 to the discharge passage 32a of the discharge nozzle 32 and discharged.

  At the time of use such as applying the hair-restoring agent or hair-styling agent to the head, the liquid application tool 1 is in an inverted state, and the liquid in the container body 10 accumulates on the discharge part side, but the flexible tube 33 has a liquid inlet. Since the weight 36 is provided on the side, the liquid suction port 33a is guided into the liquid accumulated on the discharge portion side in use, and the liquid suction port 33a does not come out of the liquid.

  In the inverted state of the liquid applicator 1, the discharge portion 30 of the container body 10 faces downward, so that the check valve 40 for introducing outside air moves the valve body 40a downward by the weight 40b and the communication hole of the valve body 40a. 40a2 is closed, and the inflow of outside air into the container body 10 is blocked in the inverted state. Further, the operation of the pump 31 for discharging the liquid in the inverted state reduces the pressure in the pump chamber 38 of the cylinder 31a to a negative pressure, and the liquid discharge check valve 35 is opened to open the container through the flexible tube 33. The liquid in the main body 10 is sucked into the pump chamber 38, and the inside of the container main body 10 becomes negative pressure. When negative pressure is generated in this way, the weight 40b of the check valve 40 for introducing outside air is lifted by negative pressure, the communication hole 40a2 of the valve body 40a is opened, and the outside air is allowed to flow into the container body 10, thereby being inverted. The operation of the pump 31 for discharging the liquid in a state is made possible.

  As described above, the check valve 40 for introducing the outside air does not block the inflow of the outside air into the container body 10 in the upright state, blocks the inflow of the outside air into the container body 10 in the inverted state, and further blocks the container body 10. When the inside becomes negative pressure, the outside air is caused to flow into the container body 10. The flexible tube 33 has a weight 36 on the liquid suction port side, and guides the liquid suction port 33a into the liquid according to the state of use. For this reason, the pump 31 is activated by the operation of pressing the discharge nozzle 32 against the part to be applied, and the liquid stored in the container body 10 is discharged from the discharge nozzle 32, so that the liquid can be applied to the hair, head, face in any use state. A sufficient and appropriate amount can be applied to the place where the skin needs. Moreover, the liquid is swept away by the discharge nozzle 32 and stimulated in contact with the scalp, and an appropriate amount of the liquid can be applied to the required place on the hair, head and face skin, and stimulated in contact with the scalp. It is possible to give. Further, when the discharge nozzle 32 discharges the liquid, it stimulates in contact with the scalp, so that an appropriate amount of liquid can be applied to a necessary place on the hair, head, and face skin, and also in contact with the scalp to give stimulation. Is possible. In this way, the liquid is directly applied to the scalp and hairline and rubbed into the skin, and the skin surface is stimulated and massaged while the liquid is scattered.

  As shown in FIG. 4 (b), in the inverted state of the liquid application tool 1, the discharge part 30 of the container body 10 faces downward, so that the check valve 40 for introducing the outside air has the slit 40g closed by the pressure of the liquid. The flow of outside air into the container body 10 is blocked. Further, the operation of the pump 31 for discharging the liquid in the inverted state reduces the pressure in the pump chamber 38 of the cylinder 31a to a negative pressure, and the liquid discharge check valve 35 is opened to open the container through the flexible tube 33. The liquid in the main body 10 is sucked into the pump chamber 38, and the inside of the container main body 10 becomes negative pressure. When this negative pressure is reached, the slit 40g of the check valve 40 for introducing the outside air is opened by the negative pressure, allowing the outside air to flow into the container body 10 and thereby operating the pump 31 that discharges the liquid in an inverted state. To.

  In this manner, the check valve 40 for introducing the outside air has the slit 40g closed in the upright state shown in FIG. 4A, and blocks the inflow of the outside air into the container body 10. In the inverted state shown in FIG. 4B, the inflow of outside air into the container body 10 is blocked, and the outside air is caused to flow into the container body 10 when the inside of the container body 10 becomes negative pressure. The slit 40g can be provided at one place or a plurality of places, and the shape of the slit 40g can be a cross, Y-shape, X-shape, star-shape, etc., and is not particularly limited.
