  However, in the conventional drug supply container, the amount of drug dissolved in water has changed due to temperature fluctuations such as air temperature and water temperature. For this reason, the concentration of the aqueous solution in which the drug is dissolved becomes unstable, and it is difficult to stably obtain the effect of the drug. Moreover, since the usage-amount of a chemical | drug | medicine changes with the fluctuation | variation of temperature, the variation in the usage period of the container had arisen.

  The present invention has been made in view of such circumstances, and can always supply a certain amount of chemical (medicine) into running water without being affected by temperature fluctuations such as air temperature and water temperature. This makes the concentration of the aqueous solution of the chemical solution constant, stabilizes the efficacy of the chemical solution, stabilizes the amount of the chemical solution used, and suppresses variations in the usage period of the container.

An outside air introduction pipe, an outflow path of a chemical solution formed in a gap between the outside air introduction pipe and the mouth, an impregnated body disposed in the pedestal and impregnated with the chemical liquid flowing out from the outflow path, The impregnated body is characterized in that a protruding portion that protrudes outward from the pedestal and is close to or in contact with the flowing water receiving surface is formed.

In the chemical solution supply container of the present invention, for example, a chemical solution (medicine) such as a fragrance or a cleaning agent accommodated in the container body flows out through the outflow path of the gap between the mouth of the container body and the outside air introduction pipe, Absorbed by the impregnated body. Also, outside air flows into the container body through the inside of the outside air introduction pipe in accordance with the volume of the chemical solution flowing out from the container body. In other words, since the outside air is stably introduced into the container body through the outside air introduction pipe, the chemical liquid flowing out from the container body to the impregnated body is successfully replaced with the outside air, and the impregnated body is stably immersed in the chemical liquid. It has come to be.
In addition, as this impregnation body, a porous sintered body, a nonwoven fabric, cloth, paper, etc. can be used, for example. Specifically, a material capable of obtaining a capillary action of a chemical solution is suitable for the impregnated body.

  And this impregnation body has the protrusion part which protrudes outside from a base, and the protrusion part is closely arranged or contact | abutted on a flowing water receiving surface. Therefore, when water flows on the running water receiving surface, the projecting portion of the impregnated body is immersed in the running water, and the chemical solution flows into the running water from this projecting portion, and is supplied stably by a certain amount. Yes.

  That is, according to the present invention, it is possible to always supply a certain amount of chemical liquid into running water regardless of temperature fluctuations such as air temperature and water temperature. Therefore, the concentration of the aqueous solution containing the chemical solution becomes constant, and the efficacy of the chemical solution can be stabilized. Moreover, since the usage amount of the chemical solution is stabilized, variations in the usage period of the chemical solution supply container can be suppressed, and the handleability is improved.

  Moreover, the chemical | medical solution supply container of this invention WHEREIN: It is preferable that the window hole which penetrates the said protrusion part and protrudes outside is formed in the surrounding wall of the said base.

  In this case, since a window hole through which the projecting portion of the impregnated body is inserted is formed in the peripheral wall, not the bottom wall of the pedestal having a bottomed cylindrical shape, it is possible to prevent water from flowing back into the container. . That is, since the window hole for projecting the protruding portion is formed in the peripheral wall, it is possible to prevent water from entering the pedestal by appropriately setting the height of the window hole. Specifically, for example, when water accumulates to a predetermined depth on the flowing water receiving surface, the window hole may be arranged so as to have a height equal to or higher than the predetermined depth.

  As a result, the concentration of the chemical solution (raw solution) impregnated in the impregnated body in the pedestal is surely suppressed from being diluted by the backflowed water, and the concentration of the aqueous solution in which the chemical solution is dissolved becomes constant. The effect obtained is more remarkable.

  According to the chemical solution supply container of the present invention, it is possible to always supply a certain amount of chemical solution (medicine) into running water without being affected by temperature fluctuations such as air temperature and water temperature, and thereby the concentration of the aqueous solution of the chemical solution. Can be stabilized, the efficacy of the chemical solution can be stabilized, the amount of the chemical solution used can be stabilized, and the variation in the use period of the container can be suppressed, thereby improving the handleability.

Accordingly, when water flows on the flowing water receiving surface 100, the protruding portion 6b of the impregnated body 6 is immersed in the flowing water, and the chemical liquid L flows out from the protruding portion 6b into the flowing water, and is supplied stably by a certain amount. It has become so.

  That is, according to the present embodiment, a constant amount of the chemical liquid L can be always supplied into running water regardless of temperature fluctuations such as air temperature and water temperature. Therefore, the concentration of the aqueous solution containing the chemical liquid L becomes constant, and the efficacy of the chemical liquid L can be stabilized. Moreover, since the usage-amount of the chemical | medical solution L is stabilized, the variation in the usage period of this chemical | medical solution supply container 1 can be suppressed, and handleability improves.

Moreover, in this embodiment, since the window hole 16 which penetrates the protrusion part 6b of the impregnation body 6 and protrudes outside the container is formed in the surrounding wall 18 of the base 3, there exists the following effect.
That is, in this case, since the window hole 16 through which the protruding portion 6b is inserted is formed in the peripheral wall 18 instead of the bottom wall 19 of the pedestal 3 having a bottomed cylindrical shape, the water may flow back into the container. Is prevented. That is, since the window hole 16 for projecting the projecting portion 6b is formed in the peripheral wall 18, by appropriately setting the height (position in the vertical direction) of the window hole 16, the inside of the base 3 (especially the impregnated body 6). It is possible to prevent water from entering into the radially inner portion of the peripheral wall 18 where the main body 6a is disposed. Specifically, for example, when water accumulates to a predetermined depth on the flowing water receiving surface 100, the window hole 16 may be disposed so as to have a height equal to or higher than the predetermined depth.

  As a result, the concentration of the chemical solution (raw solution) L impregnated in the impregnated body 6 in the pedestal 3 is reliably suppressed from being diluted by the backflowed water, and the concentration of the aqueous solution in which the chemical solution L is dissolved is constant. Thus, the above-described operational effects become more remarkable.

The tube 11 may be formed integrally with the lower tube portion 9.
Moreover, in the above-mentioned embodiment, although demonstrated using the impregnation body 6 in which the protrusion part 6b was made deformable, it is not limited to this, The protrusion part 6b may be undeformable. In this case, the protrusion 21 on the inner edge of the window hole 16 and the notch 22 of the protruding portion 6b may not be provided.

  In addition, in the range which does not deviate from the meaning of this invention, it is possible to replace suitably the component in the embodiment mentioned above by the known component, and you may combine the modification mentioned above suitably.
