FIG. 5 is a partial detailed sectional view showing an operation of taking out the inner solution at the time of liquid supply from the liquid derivative, and FIG. 6 is a partial detailed sectional view showing a state where a predetermined amount of the inner solution is taken out from the liquid derivative.
[0010]
As shown in FIG. 1 , the liquid container 401 of the embodiment includes a cylindrical tank 403 that includes a hollow portion 403 a inside and accommodates the internal solution 2, and a cylindrical protrusion from a part of the tank 403. An opening 405 that communicates the inside and outside of the tank 403 at the tip of the liquid supply unit 404, and continuously extends from the inside of the tank 403 to the opening 405. The liquid derivative 6 is disposed on the inside of the tank 403 so that the inner solution 2 in the tank 403 is sucked up to the vicinity of the opening 405 by a capillary force.
[0011]
A cap 407 is detachably fitted and mounted near the opening 405 so as to cover the opening 405 and a vent hole 408 formed in the vicinity of the opening 405 described later.
[0012]
The liquid derivative 406 is formed in a substantially cylindrical shape by a large number of synthetic fiber bundles, and can be restored even if the tip portion 406a disposed in the vicinity of the opening 405 is deformed by an external force. Further, the liquid derivative 406 is disposed over via the cylindrical holding member 409 surrounding the substantially cylindrical outer peripheral portion from the bottom of the tank 403b near within the tank 403 to the opening 405.
[0013]
As shown in FIGS. 1 and 2 , the holding member 409 extends substantially linearly from the front end 404a of the liquid supply unit 404 to the vicinity of the tank bottom 403b. The inner plug portion 409a is formed in a stepped shape with a diameter larger than that of the opening portion of the distal end portion 404a.
[0014]
A vent hole 408 is formed in the wall portion of the holding member 409 so as to communicate the inside of the tank 403 with the outside through the cylindrical portion disposed inside the tank 403 and the upper surface of the inner plug portion 409a. . As shown in FIG. 3 , the opening 408a on the upper surface of the inner plug 409a of the vent hole 408 is formed in the vicinity of the opening 405 formed in the substantially central portion of the inner plug 409a.
Further, the opening 408 b into the tank 403 of the vent hole 408 is formed close to the upper part inside the tank 403.
[0015]
When the pressure inside the tank 403 fluctuates by venting the inside of the tank 3 through the vent hole 408, for example, when the internal solution of the tank 403 decreases and the pressure inside the tank 403 decreases. The external air is taken into the tank 403 by the amount of the reduced internal solution through the vent hole 408 so that the pressure inside the tank 3 is kept constant.
[0016]
In the vicinity of the opening 405, as shown in FIG. 3 , it is formed continuously with a part of the opening 405 in a plan view and enters the inner plug 409 a inside from the inner periphery of the opening 405. A small amount of liquid supply part 420 is formed which is formed in the inner stopper part 409a and is recessed inward from the upper surface.
[0017]
As shown in FIG. 4 , the small amount of liquid supply unit 420 is notched deeper into the inside plug portion 409 a than the upper end surface of the distal end portion 406 a of the liquid derivative 406 disposed in the opening 405, and is a part of the opening 405. A liquid inflow passage 421 that is formed continuously with the portion, and a storage portion for storing the inner solution 2 that is formed to be deeply recessed inside the inner plug portion 409a than the liquid inflow passage 421 and flows into the liquid inflow passage 421. 422 is formed.
[0018]
Next, the operation of the liquid container 401 according to the embodiment will be described in detail with reference to the drawings.
In a state in which the content liquid 2 is filled in the liquid container 401, FIG. 1, as shown in FIG. 4, always inner solution 2 to the tip portion 406a of the liquid derivative 406 is impregnated by capillary force of the liquid derivatives 406 .
[0019]
When the inner solution 2 in the tank 403 is used, as shown in FIG. 5 , first, the rod body 30 is pressed against the tip 406 a of the liquid derivative 406 exposed in the opening 405, and the inside of the opening 405 is directed. Deform. Then, the tip end portion 406a is compressed and deformed by the pressure of the rod body 30, and the inner solution 2 impregnated inside is pushed out to the upper side of the tip end portion 406a, and a liquid inflow path provided adjacent to and in communication with the opening 405. It flows into the reservoir 422 through 421.
[0020]
Thereafter, as shown in FIG. 6, when the pressing by the rod 30 is stopped and the tip part 406 a is separated from the tip part 406 a, the tip part 406 a is restored to its original shape by elastic force. At this time, the inner solution 2 that is in contact with the tip 406a is again absorbed by the liquid derivative 406 from the tip 406a, but the inner solution 2a that has flowed into the reservoir 422 is not in contact with the tip 406a. A certain amount is stored in the storage section 422 without being absorbed by the storage.
[0021]
When the inner solution 2a is used, the inner solution 2a stored in the storage section 422 is used by impregnating an appropriate amount of the inner solution 2a with a thin cotton swab or the like having a capillary force.
[0022]
Here, in the liquid derivative 406, the reduced amount of the internal solution 2a stored in the storage unit 422 is quickly sucked up from the inside of the tank 403 by the capillary force, and is returned to a predetermined impregnation amount. Thus, the liquid derivative 406 can be prepared for the next supply of the inner solution 2.
[0023]
On the other hand, in the tank 403, the amount of the internal solution 2 stored in the storage unit 422 decreases, so the pressure in the tank 403 decreases. However, the volume of air that has decreased in the tank via the vent 408 is reduced. The pressure inside the tank 403 is supplied from the outside and kept constant.
[0024]
As described above, since the embodiment is configured, according to the liquid container 401, the small amount of liquid supply unit 420 is provided in the vicinity of the opening 405 for supplying the internal solution, so that the internal solution 2 is directly supplied from the liquid derivative 406. In addition, since the internal solution 2 can be precisely stored and quantitatively supplied by the storage unit 422 of the small liquid supply unit 420, the internal solution 2 can be quantitatively impregnated into the cotton swab 20 or tissue paper. . Moreover, since the inner solution 2 is retained in the reservoir 422, even a small cotton swab can be appropriately impregnated with a liquid by natural capillary force.
[0025]
In the embodiment, the configuration and material of the liquid derivative 406 and the configuration of the vent hole 408 are not limited.
[0026]
Further, in the present embodiment, the liquid derivative is configured in a substantially cylindrical shape by a large number of synthetic fiber bundles, but the present invention is not limited to the configuration of the liquid derivative. For example, the liquid derivative is formed into a fiber bundle rod shape. It may be constituted by a porous body such as a body or a sponge.
[0027]
【The invention's effect】
As described above, according to the liquid container described in the present invention, an amount of the internal solution that can be absorbed by natural capillary force can be easily obtained with a simple configuration without excessive supply to a cotton swab or tissue paper. There is an excellent effect that it can be impregnated.
[0028]
Specifically, according to the present invention, in the liquid container, the tank that stores the liquid, the opening that communicates the inside and the outside of the tank, and the opening from the inside of the tank to the opening are continuously disposed. By having a liquid derivative capable of sucking up the liquid in the tank to the vicinity of the opening by capillary force, a vent hole that ventilates the inside and outside of the tank, and a cap that prevents volatilization of the liquid in the tank. The liquid supplied from inside the tank has an amount that is sucked up by the capillary force of the liquid derivative. By pressing the liquid derivative end of the opening with a cotton swab or tissue paper, the liquid derivative An appropriate amount of liquid impregnated at the end can be impregnated into a cotton swab or tissue paper.
[0029]
Further, according to the present invention, the liquid derivative is impregnated by deforming the end portion of the liquid derivative by allowing the configuration of the liquid derivative to be restored even if the one end portion disposed in the opening is deformed by an external force. The liquid can be pushed out and used repeatedly.
Further, according to the present invention, by forming the vent hole in the vicinity of the opening, the vent hole can be sealed at the same time when the opening is sealed by the cap, and the sealed state can be ensured. .
[0030]
Further, according to the present invention, the liquid derivative is disposed via a cylindrical holding member that surrounds the outer periphery from the inside of the tank to the opening, and the air hole is formed between the holding member and the tank inner wall portion. Thus, the tank and the opening can be formed with a simple configuration, the assembly work can be facilitated, and the vent hole can be reliably configured.
[0031]
Further, according to the present invention, a small amount of liquid supply section is provided near the opening by providing a small amount of liquid supply section that stores a liquid that overflows when one end of the liquid derivative disposed in the opening is pressed. Therefore, the liquid can be quantitatively impregnated into a cotton swab, tissue paper or the like, and even a small cotton swab can be appropriately impregnated with liquid by natural capillary force.
The above remarkable effects are exhibited.
