Japanese Utility Model Publication No. 51-47562 Design registration No. 1460784 Japanese Patent No. 6383082

However, in the conventional liquid medicine applicator device 100, the liquid medicine cannot be supplied to the applicator body 110 unless the applicator part 100 is directed downward so that the applicator body 110 faces the application site and the protruding part 321 is pressed.
Moreover, in the cases of Patent Documents 2 and 3, the application portion is the same.
Therefore, in any case, in the case of an elderly person with a narrow range of motion of the shoulder joint or a person with weak strength, the applicator main body 110 is pressed against the applicator site on the user's back, and the projecting portion 321 is pushed by the biasing force of the spring portion 323. It is difficult to push against it.

Therefore, when an elderly person with a narrow range of motion of the shoulder joint or a person with weak strength applies the medicinal solution to his or her back by himself, the applicator main body 110 is pressed against the arm in front of the body, and the applicator portion is first pressed. After the main body 110 is pressed and deformed, the protrusion 321 is pushed in to wet the applicator main body 110 with the liquid medicine, and then the liquid medicine applicator 100 must be turned around the back to apply the liquid medicine.
On the other hand, the area of the application target position is large, and it may not be possible to apply the liquid medicine to the entire range of the application target position only by wetting the application unit main body 110 once. In this case, it is troublesome to return the liquid medicine applicator 100 to the front of the body and press the applicator main body 110 against the arm to re-wet the applicator main body 110 .

In view of the above circumstances, the object of the present invention is to provide a liquid medicine applicator that can easily supply a liquid medicine from a container to the applicator body regardless of whether the applicator part faces upward or downward. there is

Figure 2 is a half-sectional view of the container of the applicator device of Figure 1; FIG. 2 is a cross-sectional view of a main part of a nozzle unit of the applicator of FIG. 1; It is explanatory drawing of the use condition of the applicator of FIG. It is a principal part sectional view of the conventional applicator.

The present invention will be described in detail below with reference to the drawings showing its embodiments.
1 and 2 show a first embodiment of a chemical liquid applicator according to the present invention.

As shown in FIGS. 1 and 2, this chemical liquid applicator 1 includes a container 2 serving as a chemical liquid reservoir, a nozzle unit 3 and a cap 4 .
As shown in FIG. 3, the container 2 is a peelable container and includes an outer container 22 made of flexible resin and an inner container 23 .

The outer container 22 is provided with a male thread 22 on the outer periphery of the mouth portion 20, and is provided with a vent hole 24 that communicates with the inside and outside of the outer container 22, and is always in a steady shape in a state where it is not subjected to pressure from the outside. The shape is restored to
The inner container 23 is thinner than the outer container 22, and only the mouth portion 20 thereof is integrated with the outer container 22, and is filled with a chemical solution (not shown).

The nozzle unit 3 includes a nozzle body 30 , an application section 35 and a cap 4 .
The nozzle body 30 has a housing 31 and a female screw cap portion 32 .

The housing 31 is made of thermoplastic resin such as polycarbonate, polyamide, polyethylene terephthalate, polyvinyl chloride, polyethylene, ABS resin, fluororesin, etc. As shown in FIG. is provided with a tube 33 and a pressure relief valve 34.
The pressure release valve 34 includes an inlet nozzle 34a, a valve body 34b, and a discharge nozzle 34c. 34b is fitted to the tip of the housing 31. As shown in FIG.

In the pressure release valve 34, the valve body 34b is provided therein with a chemical liquid passage that communicates with the inlet side nozzle 34a and the discharge side nozzle 34c (not shown). It has a valve body and a stainless steel coil spring that urges the spherical valve body against a valve seat provided in the chemical channel with a force of 3.4 kPa in a direction to close the chemical channel.
That is, the pressure relief valve 34 has a set pressure of 3.4 kPa.

The tube 33 is made of, for example, thermoplastic resins such as polycarbonate, polyamide, polyethylene terephthalate, polyvinyl chloride, polyethylene, fluororesin, and elastomers thereof, has flexibility, and has one end connected to the inlet side nozzle of the pressure release valve 34. 34a.

The female screw cap portion 32 is made of, for example, thermoplastic resin such as polycarbonate, polyamide, polyethylene terephthalate, polyvinyl chloride, polyethylene, ABS resin, or fluororesin, is fused or adhered to the housing 31 , and is attached to the male screw portion 21 of the container 2 . A female screw portion (not shown) to be screwed is detachably attached to the mouth portion 20 of the container 2, and as shown in FIG. there is
That is, the tube connection nozzle 32 is connected to the tube 33 so that the container 2 and the pressure release valve 34 can be communicated with each other via the tube 33 and the inlet nozzle 34a.

The applicator 35 has a ring shape that supports the applicator main body 35a made of a spongy material such as an open-cell polyurethane resin foam and the peripheral edge of the applicator main body 35a and the tip of the housing 31 so as to be sandwiched therebetween. The frame portion 35b is bonded or fused integrally with the housing 31. As shown in FIG.
The tip of the discharge side nozzle 34c of the pressure release valve 34 is substantially in contact with the applicator main body 35a, so that the liquid medicine discharged from the discharge side nozzle 34c is smoothly impregnated.

The applicator container 2 is constructed as described above. When the cap 4 is removed and the container 2 is pressed from the outside by gripping the container 2 with a hand, the application container 2 is dented inside the outer container 22 by the pressing force. As a result, pressure is applied in the direction in which the inner container 23 is recessed.
When the liquid pressure in the inner container 23 reaches 3.4 kPa or higher, the spherical valve element moves in the direction of opening the chemical solution passage against the biasing force of the coil spring, and the chemical solution in the inner container 23 is discharged. It is supplied to the applicator main body 35a through the side nozzle 34c and impregnates the applicator main body 35a.

On the other hand, when the pressure on the outer container 22 is released and the liquid pressure in the inner container 23 becomes less than 3 kPa, the urging force of the coil spring causes the spherical valve body to be pressed against the valve seat to close the chemical liquid passage. The ejection of the chemical liquid from the nozzle 34c is stopped.
In addition, since air enters the gap between the inner container 23 and the inner container 23 through the vent hole 24, the outer container 22 is restored to its original shape by its elastic restoring force. The inner container 23 is maintained in a state where the volume is reduced by the discharge amount of the chemical solution, and the gap volume between the outer container 22 and the inner container 23 is increased by approximately the discharge amount of the chemical solution. Moreover, the chemical liquid remaining in the inner container 23 and the tube 33 is not exposed to the outside air.

When the application portion main body 35a is impregnated with the liquid medicine, the liquid medicine can be applied to the application position by moving the application container 2 while the application portion main body 35a is in contact with the application position.
Further, when the chemical liquid impregnated in the application portion main body 35a is exhausted, the container 2 may be pressed again from the outside until the liquid pressure of the chemical liquid reaches 3.4 kPa or more.

As described above, the chemical liquid applicator 1 is provided with the pressure release valve 34 having a set pressure of 3.4 kPa at the discharge end of the liquid flow path. When the liquid pressure of the liquid medicine reaches 3.4 kPa or more, the pressure relief valve 34 is opened, and the liquid medicine is supplied from the discharge side nozzle 34c of the pressure relief valve 34 to the application section main body 35a.
Therefore, it is not necessary to press the applicator body 35a to the applicator position to open the valve as in the conventional art.

That is, the medicinal solution applicator 1 supplies the medicinal solution to the applicator main body 35a simply by applying pressure to the container 2 by grasping the container 2, regardless of whether the applicator main body 35a faces upward or downward. can do. Therefore, there is no need to press the applicator main body 35a against the back or the like with the applicator main body 35a facing downward, so that even elderly people who have difficulty reaching around the back can easily apply the liquid medicine to the application target position.

Moreover, since the set pressure of the pressure release valve 34 is 3.4 kPa, there is no need to raise the hydraulic pressure greatly, and even an elderly person with a weak grip can easily raise the hydraulic pressure to the set pressure.
Moreover, since the set pressure of the pressure release valve 34 is 3.4 kPa, the pressure release valve 34 will not be opened only by the weight of the chemical unless an external pressure is applied to the container 2 .
That is, unless an external pressure is applied to the container 2, even if the container 2 is tilted so that the applicator main body 35a side faces downward, the liquid medicine will not leak to the outside.

Furthermore, in this chemical liquid applicator 1, the container 2 is a peeling container, and the pressure release valve 34 is provided on the discharge outlet side of the chemical liquid flow path. 22 returns to its original shape, but the inner container 23 is held in a contracted state and is closed by the spherical valve body of the pressure release valve 34 having the chemical liquid flow path.
That is, even if the cap 4 is forgotten to be attached, there is little risk that the chemical solution will be exposed to the outside air and deteriorated by germs, etc., that the chemical solution will be oxidized, or that the volatile components in the chemical solution will volatilize and the efficacy will deteriorate.

In this chemical liquid applicator 1, since the pressure release valve 34 is composed of a stainless steel spherical valve body and a coil spring, the chemical liquid flow path is stably closed without corrosion of the spherical valve body and the coil spring. can do.

The invention is not limited to the embodiments described above. For example, in the above embodiments, the container is a peeling container, but the container may be a single-layer container as long as the liquid pressure of the chemical solution can be increased.
Further, for example, the bottom side of the container is pinched by hairpin-shaped squeezing means, and in a state in which the container is pinched by the squeezing means, the squeezing means is involved, and the liquid pressure in the container is increased by the squeezing to apply the chemical solution to the application portion. It does not matter as a configuration to send.

In the above embodiment, the pressure relief valve is composed of a stainless steel spherical valve body and a coil spring, but it may be of other valve structure such as a diaphragm valve depending on the type of chemical solution.
In the above embodiment, the application portion is made of a sponge-like material, but it may be made of very fine, dense bristles.
