This medicine supply device is provided with a medicine outlet hole at the bottom of a chemical tank (drug container) for storing a liquid medicine, the medicine is led out from the outlet hole into the impregnated body and impregnated. The chemicals contained in the impregnated body are dissolved in water and flowed down into the low tank.

JP 2001-342666 A

  The above-described drug supply device is structurally complex and expensive to manufacture. On the other hand, as shown in FIG. 13A, a simpler mechanism is composed of a chemical solution tank 1 for storing the chemical solution A and a cap 3 attached to the bottom opening 2 of the chemical solution tank 1. A chemical solution discharge container 100x provided with a chemical solution discharge nozzle 4 and a foot 6 can be considered. The chemical liquid A is held in the distal end opening 5 of the chemical liquid discharge nozzle 4 by the surface tension and the inside of the chemical liquid tank 1 being in a weak negative pressure state.

  As shown in FIG. 13 (b), this chemical solution discharge container 100x is placed on the water suction port 21 of the hand-washing part 20 of the low tank, and the water in the flush toilet is flushed to make the hand-washing part 20 as shown by the arrow. When the water W is supplied to the water tank, the water W flows down into the low tank so as to wash the chemical liquid discharge nozzle 4 holding the chemical liquid A, so that the chemical liquid A is mixed into the low tank. Further, even after the water supply from the currant is stopped, the temperature in the chemical liquid tank rises as compared with the time of the water supply, and the chemical liquid A may be discharged and mixed into the raw tank when the head space expands. Therefore, according to the chemical solution discharge container 100x, the chemical solution A can be mixed into the raw tank by a simple mechanism.

  However, according to the chemical solution discharge container 100x, when the chemical solution A is discharged, air is mixed into the chemical solution tank 1 to reduce the amount of the chemical solution A, and water is mixed to dilute the chemical solution A. Therefore, if the time when all of the chemical liquid A in the chemical liquid tank 1 is discharged is the time when the use of the chemical liquid discharge container 100x is to be terminated, the chemical liquid is diluted when water is mixed, There is a problem that the use is continued until the time when a chemical solution having insufficient medicinal effect is discharged.

  On the other hand, according to the present invention, the chemical liquid is reliably discharged when water is supplied from the currant and the water from the currant is actively mixed into the chemical tank by an appropriate combination of the physical properties of the chemical and the structure of the chemical discharge container. And reducing the amount of liquid in the chemical tank by causing replacement of the chemical and water, thereby preventing the end of use of the chemical discharge container from the remaining amount of liquid in the chemical tank Then, it is an object of the present invention to accurately determine the end of use based on matters associated with a decrease in chemical concentration such as the color of the diluted chemical.

  In the chemical solution discharge container having a simple mechanism that is placed in the hand-washing portion with a low tank of the flush toilet, the present inventors ensure that the chemical solution is filled with a specific gravity of 1.00 or more so that the chemical solution is reliably supplied when water is supplied from the currant. As the liquid is discharged, the chemical liquid is replaced with water, and the chemical liquid in the chemical liquid tank is found to be diluted with water. It was found that it is possible to accurately determine when to end use.

That is, the present invention comprises a chemical solution tank for storing a chemical solution, and a chemical solution discharge nozzle provided below the chemical solution tank, and is placed on the hand wash part of the low tank of the flush toilet, and the tip opening of the chemical solution discharge nozzle is the hand wash part. Is a chemical discharge container in which the chemical liquid is washed with water, discharged from the chemical liquid tank through the chemical liquid discharge nozzle, water enters the chemical liquid tank, and the chemical liquid is diluted with water,
The specific gravity of the chemical solution is 1.00 or more and 1.50 or less,
The viscosity of the chemical solution is 1 to 3000 mPa · s,
The narrowest flow path area in the chemical solution discharge nozzle is 0.2 to 80 mm ²
A chemical solution discharge container is provided.

  In addition, the present invention provides a toilet cleaning product in which the chemical liquid tank of the above-described chemical liquid discharge container is filled with a colored toilet cleaning liquid.

  According to the present invention, in the chemical solution discharge container that can mix the chemical solution in the chemical solution tank into the raw tank by a simple mechanism by placing it in the hand washing part of the low tank of the flush toilet, it is ensured when water is supplied from the currant. The chemical solution can be discharged, and further, the chemical solution in the chemical solution tank can be actively replaced with water and diluted with water by discharging the chemical solution at the time of water supply from the currant. Therefore, it is possible to accurately know the time when the use of the chemical solution should be ended with the color of the diluted chemical solution.

  Hereinafter, the present invention will be described in detail with reference to the drawings. In each figure, the same numerals indicate the same or equivalent components.

  FIG. 1 is a partial sectional view of a toilet cleaning product 200A filled with a chemical solution A in a chemical solution discharge container 100A according to an embodiment of the present invention, a partially enlarged sectional view (a), a side view (b), and a top view. (C) and bottom view (d).

  The chemical solution discharge container 100 </ b> A includes a chemical solution tank 1 and a cap 3 attached to the bottom opening 2 of the chemical solution tank 1.

  The chemical liquid tank 1 is filled with a chemical liquid A such as a toilet fragrance, a cleaning agent, and a disinfectant.

  When the specific gravity of the chemical solution A is equal to or higher than the specific gravity of the water supplied from the currant, the water supplied from the currant replaces the chemical solution A in the chemical solution tank 1. More specifically, at the time of water supply from the currant, the chemical liquid A in the chemical liquid tank 1 is replaced with water in the water flow with which the tip opening 5 of the chemical liquid discharge nozzle 4 is in contact, and is discharged into the water flow. Therefore, the specific gravity of the chemical solution A is equal to or higher than the specific gravity of the water supplied from the currant, and under normal use conditions, the specific gravity of the chemical solution A at 20 ° C. is set to 1.00 or higher, preferably from the viewpoint of ease of water replacement. The lower limit of the specific gravity (20 ° C.) is made larger than 1.00, more preferably 1.02 or more, and further preferably 1.03 or more. On the other hand, when the specific gravity of the chemical liquid is smaller than water, even if the tip opening 5 of the chemical liquid discharge nozzle 4 is in contact with water, the chemical liquid A in the chemical liquid tank 1 is hardly replaced with water.

  On the other hand, the upper limit of the specific gravity is set to 1.50 or less from the viewpoint of suppressing the natural fall (so-called dripping) of the chemical liquid A from the chemical liquid tank 1 while the water supply from the currant is stopped. 20 or less, more preferably 1.15 or less.

  The viscosity (20 degreeC) of the chemical | medical solution A shall be 1-3000 mPa * s. This viscosity is a value measured with a B-type viscometer (60 rpm) at 20 ° C. As the rotor used for the measurement, an appropriate one from a predetermined viscosity value is used.

  If the viscosity is too low, the chemical solution A is likely to be discharged excessively. On the other hand, if the viscosity is too high, the fluidity of the chemical solution A decreases and is not discharged. A can be discharged from the chemical liquid discharge nozzle 4.

  During use of the toilet cleaning product 200A, the chemical solution A in the chemical solution tank 1 is diluted with water supplied from the currant, the specific gravity approaches 1.00, and the viscosity gradually approaches 1 mPa · s. When the chemical liquid A having a specific gravity and viscosity of 100% and the chemical liquid discharge container 100A of the present invention are used, the effects of the present invention are exhibited.

  A chemical solution discharge nozzle 4 is formed integrally with the cap 3 at the bottom of the cap 3. The tip 4a of the chemical solution discharge nozzle 4 has a small diameter, and a filter 14 is filled therein.

In the present invention, the narrowest channel area in the chemical solution discharge nozzle 4 is set to 0.2 to 80 mm ² . Here, the narrowest flow path area in the chemical liquid discharge nozzle 4 is the smallest of the net flow area in the cross section perpendicular to the flow-down direction of the chemical liquid A in the chemical liquid discharge nozzle 4. The area of the narrowest part among the net flow paths in 4 is said. Accordingly, in the chemical solution discharge container 100A, when the chemical solution discharge nozzle 4 is not filled with the filter 14, the tip opening portion 5 is the portion where the area of the flow path cross-section is minimized. However, when the chemical solution discharge nozzle 4 is filled with the filter 14 as shown in FIG. 1A, the area of the chemical solution discharge nozzle 4 at the portion where the filter 14 is filled is the same. When the narrow channel area (the minimum value of the net channel area obtained by subtracting the area occupied by the filter 14 from the channel area of the chemical solution discharge nozzle 4 itself) is smaller than the opening area of the tip opening 5, the filter 14 is filled. The narrowest flow path area of the chemical solution discharge nozzle 4 at the site where the liquid is present is within the above range. Moreover, when the flow path of the intermediate part of a chemical | medical solution discharge nozzle is thinner than the front-end | tip opening part, let the flow path area of the thin diameter part be the above-mentioned range.

  The discharge amount of the chemical liquid A depends on the area of the narrowest portion of the flow path in the chemical liquid discharge nozzle 4, and if the value is too small, the chemical liquid A is difficult to be discharged, and if it is too large, the water supply from the currant is stopped. In the meantime, the replacement of the chemical liquid and the air continuously occurs through the chemical liquid discharge nozzle 4, and the chemical liquid A disappears rapidly regardless of whether the toilet is used or not. By setting the range, an appropriate amount of the chemical liquid A can be discharged.

  The narrowest flow path area in the chemical liquid discharge nozzle 4 can be adjusted by the type of the filter filled in the chemical liquid discharge nozzle 4 in addition to the diameter of the front end opening of the chemical liquid discharge nozzle 4 or the cross section of the nozzle hole. Moreover, it can be adjusted depending on whether the chemical solution discharge nozzle 4 has a single-hole structure (see FIGS. 6A to 6E) or a porous structure (see FIGS. 6F to 6H). . Therefore, according to this invention, the freedom degree of design of the chemical | medical solution discharge nozzle 4 increases, and the shaping | molding operation | work becomes easy. In particular, when the chemical liquid discharge nozzle 4 having the smallest narrow channel area is manufactured, the diameter of the tip opening 5 of the chemical liquid discharge nozzle 4 does not necessarily have to be small, so that the chemical liquid discharge nozzle 4 can be easily molded. .

  In the present invention, the shape of the chemical liquid discharge nozzle 4 may be a cylindrical shape in which the inner diameter b is the same as the diameter a of the tip opening 5 as shown in FIG. Thus, it is preferable that the aperture nozzle 5 has a narrow aperture nozzle a having a smaller diameter a than the inner diameter b. As a result, when water or air is sucked from the tip opening 5 due to the negative pressure in the chemical liquid tank 1, it is possible to prevent the chemical liquid discharge nozzle 4 from being closed due to them and causing a discharge failure of the chemical liquid A.

  Further, as the shape of the chemical solution discharge nozzle 4, it is preferable that the tip portion 4a has an acute angle as shown in FIG. As a result, the surface tension for holding the chemical liquid A in the tip opening 5 is weakened, and the chemical liquid A held in the tip opening 5 is reliably washed with water each time water is supplied from the currant and discharged into the low tank. It becomes like this. As an aspect which makes the front-end | tip part 4a an acute angle, as shown in FIG. 5, you may narrow the outer diameter and internal diameter of the chemical | medical solution discharge nozzle 4 toward a front-end | tip part.

  There is no restriction | limiting in particular about the cross-sectional shape of the chemical | medical solution discharge nozzle 4. FIG. For example, when the chemical solution discharge nozzle 4 has a single-hole structure, it is not only a circle as shown in FIG. 6A, but also an ellipse (FIG. 6B), a rectangle (FIG. 6C), a star (FIG. (D)), a triangle ((e) in the figure), and the like. In the case of a porous structure, a plurality of holes may be formed in the nozzle substrate as shown in FIGS. 6 (f) and 6 (g), and inside the nozzle 4 ′ having a single hole structure as shown in FIG. 6 (h). Alternatively, the flow path partition member 15 having a lattice-like cross section may be fitted.

  The filter 14 is filled in the chemical solution discharge nozzle 4 as necessary in order to adjust the narrowest flow path area of the chemical solution discharge nozzle 4. As this filter 14, it is preferable to use a material having good water permeability. For example, the filter 14 is composed of an open-cell foam of a synthetic resin such as polyurethane, polyethylene, nylon, or melamine, a layer of honeycomb, mesh, or net. A woven fabric, a nonwoven fabric, a metal fiber aggregate, or the like having a dimensional skeleton structure can be used. Among them, an open cell foam having 5 to 50 cells / 25 mm is preferable, and an open cell urethane foam is particularly preferable. In addition, when filling open-cell foam, the larger the number of cells, the smaller the discharge amount of chemical solution A. Therefore, the discharge amount of chemical solution A can be adjusted by appropriately selecting the number of open-cell urethane foam cells to be used. can do.

  In the toilet cleaning product of the present invention, the tip opening 5 of the chemical solution discharge nozzle 4 is adjusted by adjusting the specific gravity, viscosity, and narrowest flow area of the chemical solution discharge nozzle 4 to a predetermined range as described above. The chemical solution A is held by the surface tension and the inside of the chemical solution tank 1 being in a weak negative pressure state. While the tip opening 5 is in contact with the water supplied from the currant, the chemical solution A is surely watered. To be discharged.

The amount of chemical A discharged per flush in the flush toilet is such that the effect of the chemical is fully exerted, and that the number of sustained use in the toilet is increased by suppressing the excessive discharge of the chemical, It is preferable to use an appropriate amount according to the concentration and the like (for example, 0.05 to 0.5 g of chemical discharge amount per flash, 0.1 to 0.2 g in consideration of use for one month). Within the scope of the present invention, it is preferable to appropriately combine the specific gravity and viscosity of the chemical liquid A and the narrowest flow path area of the chemical liquid discharge nozzle 4. For example, when the specific gravity of the chemical solution A is 1.08,
When the viscosity (20 ° C.) of the chemical liquid A is 50 to 300 mPa · s, the narrowest flow path area of the chemical liquid discharge nozzle 4 is preferably 0.8 to 7 mm ² .
When the viscosity (20 ° C.) of the chemical solution A is 300 to 500 mPa · s, the narrowest channel area of the nozzle is 3 to 13 mm ² ,
When the viscosity (20 ° C.) of the chemical solution A is 500 to 1500 mPa · s, the narrowest channel area of the nozzle is 7 to 28 mm ² ,
When the viscosity (20 ° C.) of the chemical solution A is 1500 to 2000 mPa · s, the narrowest channel area of the nozzle is 20 to 38 mm ² ,
When the viscosity (20 ° C.) of the chemical solution A is 2000 mPa · s or more, the narrowest flow path area of the nozzle is preferably 28 to 50 mm ² .

  Further, when the specific gravity is increased, since the discharge amount of the chemical liquid increases, it is preferable to adjust the appropriate discharge amount of the chemical liquid by reducing the viscosity and reducing the narrowest flow path area of the nozzle.

  As chemical | medical solution A, what is resistant to the chlorine contained in tap water, and contains colorants, such as blue and green safe to a human body, is preferable. Further, the degree of coloring by the colorant can be visually recognized at least at the concentration filled in the chemical liquid tank 1, even if the color cannot be visually recognized at the concentration at which the chemical liquid A is mixed in the raw tank, The color at the time of filling and the color at the time of dilution at which the use should be finished should be visually distinguishable.

  The liquid chemical tank 1 is made of a transparent or translucent material so that the state of the color of the liquid chemical A filled therewith can be observed from the outside of the liquid chemical tank 1 as it is diluted with water. Is preferred.

  It is preferable that a water guiding structure is provided at the bottom of the cap 3 so that the water supplied from the currant flows toward the chemical liquid discharge nozzle 4 and flows down along the chemical liquid discharge nozzle 4. In the chemical solution discharge container 100A of FIG. 1, eight plate-like portions 7 erected radially around the chemical solution discharge nozzle 4 are provided integrally with the cap 3 as one aspect of the water guiding structure. Further, the cap 3 is integrally provided with a foot 6, and further, extends around the chemical liquid discharge nozzle 4 along the chemical liquid discharge nozzle 4, and its tip is more than the front end opening 5 of the chemical liquid discharge nozzle 4. Four protruding water amount adjusting plates 8 are provided.

  The plate-like portion 7 and the water amount adjusting plate 8 are provided as necessary in the present invention. By providing the plate-like portion 7 radially with the chemical solution discharge nozzle 4 as the center, regardless of the shape of the hand-washing portion 20 of the low tank, the amount of water in the hand-washing water, the water pressure, the placement position of the chemical-solution discharge container 100A in the hand-washing portion 20, etc. The water supplied from the currant can flow along the plate-like portion 7 toward the chemical liquid discharge nozzle 4, and then flow down along the chemical liquid discharge nozzle 4 into the raw tank. Further, since the bottom surface of the cap 3 is prevented from blocking the water inlet 21, it is possible to prevent water from overflowing into the hand-washing portion 20.

  Further, by providing the water amount adjusting plate 8 so as to protrude from the front end opening 5 of the chemical liquid discharge nozzle 4, the water W from the currant continues to be excessively applied to the front end opening 5 of the chemical liquid discharge nozzle 4, and the excessive amount of the chemical liquid A is present. It is possible to prevent the discharge from being caused.

  Note that the modes of the water guiding structure and the water amount adjusting plate 8 are not limited to the above examples. For example, as long as the plate-like portion 7 forming the water guiding structure rises radially around the chemical solution discharge nozzle 4, the shape thereof may be a flat plate or a curved plate. The number of the plate-like portions 7 is not limited to 8 and may be a plurality of, preferably 4 to 12. The amount of water adjusting plate 8 is not limited to four, but may be a plurality of, preferably 3 to 8.

  A top plate 10 is detachably provided on the chemical tank 1. In the present invention, the top plate 10 prevents the water W from directly hitting the chemical liquid tank 1 when the curan water is supplied from directly above the chemical liquid discharge container 100A. In order to stabilize the discharge amount of the chemical liquid A regardless of fluctuations in water temperature or air temperature, it is provided as necessary. Moreover, since the water supplied from the currant flows radially along the top plate 10 and exhibits a beautiful water veil appearance, it is also preferable from the viewpoint of improving the usability of the chemical solution discharge container 100A.

  The top plate 10 is formed of a colored member so as to exhibit the appearance color of the chemical liquid tank 1 when the chemical liquid A in the chemical liquid tank 1 is diluted to a predetermined ratio with water. As a method of forming such a top plate 10, for example, first, the chemical solution concentration required to obtain a sufficient medicinal effect for the chemical solution A is examined, and then the chemical solution having the concentration (for example, the original chemical solution) Is diluted to 5%) in the chemical tank 1. And the color of the resin material which forms the top plate 10 is matched with the external color of the chemical | medical solution tank 1 filled with this chemical | medical solution. By adjusting the color tone of the top plate 10 in this way, it is possible to easily determine when the use of the chemical solution A in the chemical solution tank 1 should be terminated from the contrast between the appearance color of the chemical solution tank 1 and the color of the top plate 10. be able to.

  Further, in order to make such a determination easier, the top plate 10 is made of an opaque material that cannot be seen through than the transparent material that can clearly see through the chemical tank 1 through the top plate 10 or It is preferable to form from a semi-transparent material having an appropriate hiding property.

  In addition, as a method for adjusting the color tone of the top plate 10, in addition to adjusting the color of the resin material forming the top plate 10 as described above, it is also possible to apply a predetermined color sticker to the top plate 10, Since the seal is formed separately from the top plate 10, the cost is high, and since it is frequently exposed to water from the currant, there is a possibility that the pasted seal may fall off. It is preferable to form itself in a predetermined color.

  As a method for using the toilet cleaning product 200A, first, in the state where the chemical solution A that has not been diluted with water from the currant is stored in the chemical solution tank 1, the toilet cleaning product 200A is hand-washed in a low tank with a hand-washing toilet. The chemical solution discharge nozzle 4 is inserted into the water suction port 21. In this state, the chemical liquid A is held in the tip opening 5 of the chemical liquid discharge nozzle 4 by the surface tension and the weak negative pressure in the chemical liquid tank 1.

  A case where a currant is provided on the water inlet 21 of the low tank and water is supplied from above the chemical tank 1 will be described below. However, there is no curan on the water inlet 21 of the low tank, and accordingly, When the chemical liquid discharge nozzle 4 is inserted into the water suction port 21, the toilet cleaning product 200 </ b> A can be used even when water is supplied from the side of the chemical liquid tank 1.

  As shown in FIG. 2, after the toilet cleaning product 200 </ b> A is placed on the hand-washing unit 20, when the water in the flush toilet is flushed and water is supplied from the currant, the water W is first radial along the top plate 10. And then flows into the hand washing section 20 along the side surface of the chemical tank 1. The water W that has flowed into the hand-washing portion 20 flows along the plate-like portion 7 toward the chemical solution discharge nozzle 4 and enters the low tank so as to wash the tip opening 5 of the chemical solution discharge nozzle 4. Therefore, the chemical solution A held in the tip opening 5 is swept away by the water W and reliably mixed into the raw tank. Then, depending on the amount of the chemical liquid mixed from the chemical liquid tank 1 into the raw tank, the water, the diluted liquid of chemical liquid or the air adhering to the tip opening 5 immediately enters the chemical liquid tank 1 and the front opening of the chemical liquid discharge nozzle 4 is opened. The liquid medicine A is held in the part 5.

  When the water supply from the currant stops, there is no flow of water exposing the chemical liquid A held in the tip opening 5 of the chemical liquid discharge nozzle 4, and the discharge of the chemical liquid A into the raw tank by this flow also stops. Thereafter, when the head space of the chemical liquid tank 1 expands due to the relationship between the water temperature and the air temperature, the chemical liquid A is discharged into the raw tank as needed.

  Thereafter, this action is repeated by water supply from the currant, the chemical solution A is mixed into the raw tank, and the chemical solution in the chemical solution tank 1 is gradually diluted. Therefore, as shown in FIG. 3 (a), the color of the external appearance of the chemical tank 1 and the color of the top plate 10 were initially clearly distinguished from each other. ), The appearance color of the chemical tank 1 and the color of the top plate 10 are almost the same. At this point, the user of the chemical solution discharge container 100A knows that the chemical solution A has been diluted to such an extent that it does not have a sufficient medicinal effect, and regardless of the remaining amount in the chemical solution tank 1, You can stop using it. Therefore, according to the chemical solution discharge container 100A, it is possible to prevent a situation in which the chemical solution A having no sufficient medicinal effect is continuously used.

  The chemical solution discharge container of the present invention can take various other forms. For example, as in the chemical solution discharge container 100B shown in FIG. 7, in the chemical solution discharge container 100A of FIG. 1 described above, the top plate 10 has an area 10a that exhibits the appearance color of the chemical solution tank 1 before the chemical solution A is diluted with water. Then, a region 10b that exhibits the appearance color of the chemical solution tank 1 when the chemical solution A is diluted to the extent that the use should be terminated may be formed, or an intermediate color region between these regions may be formed. . As a result, even if the user of the chemical solution discharge container 100B does not clearly remember the appearance color of the chemical solution tank 1 when it is first used, the external color of the chemical solution tank 1 is diluted as needed. Compared with the external color area 10a of the chemical liquid tank 1 before the use, the external color area 10b of the chemical liquid tank 1 at the time when the use should be terminated, or the intermediate color area of these, the use of the chemical liquid A is started (FIG. 7). The end of use (FIG. 7 (b)) can be clearly distinguished from (a)).

  FIG. 8 is a side view of a chemical liquid discharge container 100C according to a different embodiment of the present invention. This chemical solution discharge container 100C is not provided with a top plate, and the cap 3 is formed of a colored member exhibiting the appearance color of the chemical solution tank 1 when the chemical solution A is diluted to the extent that the use should be terminated. Also with this chemical solution discharge container 100B, the start of use of the chemical solution A (Fig. A) and the end of use (Fig. B) can be clearly distinguished by comparing the appearance color of the chemical solution tank 1 and the color of the cap 3. It is possible to accurately know when to end the use of the chemical solution A.

  Thus, in the chemical solution discharge container of the present invention, where the colored member having the appearance color of the chemical solution tank when the chemical solution is diluted with water is provided, the color of the colored member is compared with the appearance color of the chemical solution tank 1. There is no particular limitation as long as it can be done.

  Furthermore, in the present invention, the colored member as described above is not necessarily provided. For example, a colored region in which visibility is improved after dilution than before dilution may be formed in the chemical solution tank so that the time when the use of the chemical solution should be terminated can be known. More specifically, like the chemical solution discharge container 100D shown in FIG. 9, the plate 11 in which “END” is written in almost the same color as the chemical solution before dilution is raised in the chemical solution tank 1 in advance, and the chemical solution A is Fill. As a result, in the state where the chemical solution A is not diluted, the letters “END” are concealed by the chemical solution A and cannot be seen from the outside of the chemical solution tank ((a) in the figure), but from the background as the chemical solution is diluted. It becomes possible to clearly see when it is raised and when the use of the chemical solution is to be finished, and it becomes possible to know the time when the use of the chemical solution is to be finished ((b) in the figure).

  In addition, the individual components such as the chemical liquid tank 1 and the chemical liquid discharge nozzle 4 are not limited to the illustrated modes, and can take various shapes.

(1) Relationship between the specific gravity of chemical liquid and the discharge amount In order to investigate the relationship between the specific gravity of chemical liquid and the discharge amount, a chemical liquid discharge container (chemical liquid tank capacity 95 mL) similar to the chemical liquid discharge container 100A of FIG. Two containers A1 and A2 in which the chemical solution discharge nozzle was not filled with a filter were produced. The container A1 has a diameter a of the tip opening of the chemical solution discharge nozzle and an inner diameter of the center of the nozzle of 6.0 mm (opening area = the narrowest channel area = 28 mm ² ), and the container A2 has a diameter of the tip opening. a is 1.0 mm (opening area = narrowest channel area = 0.8 mm ² ), and the inner diameter b of the central portion is 4 mm.

  On the other hand, as shown in Table 1, six types of chemicals of 1A to 1F having different viscosities at a viscosity (20 ° C.) of 100 mPa · s, and three types of 1G to 1I having viscosities (20 ° C.) of 7 mPa · s and different specific gravities. The chemical solution was prepared and filled with 80 g of the chemical solution discharge containers A1 and A2. Then, the tip opening of the chemical solution discharge nozzle is immersed in 1 L of still water for 1 minute (room temperature 23 ° C., water temperature 23 ° C., chemical solution temperature 23 ° C.), and the blue absorbance (630 nm) of the water is measured. The amount of the chemical solution discharged from the chemical solution tank into 1 L of still water was calculated. The result is shown in FIG.

From FIG. 10, by setting the specific gravity of the chemical solution to 1.00 or more, the chemical solution can be discharged into the water from the chemical solution tank, in particular, the container A1 (the narrowest channel area of the chemical solution discharge nozzle is 28 mm ² ), and the chemical solution viscosity is 100 mPa · s. It can be seen that by setting the specific gravity to 1.05 or more, the chemical solution discharge speed increases.

(2) Relationship between chemical solution viscosity and discharge amount In order to examine the relationship between the chemical solution viscosity and discharge amount, five types of chemical solutions 2A to 2E having different viscosities (20 ° C.) were prepared as shown in Table 2. .

80 g of these five kinds of chemical solutions are respectively filled in the chemical solution discharge container A1 (chemical solution tank capacity 95 mL, the narrowest channel area of the chemical solution discharge nozzle 28 mm ² ) prepared in (1). The tip opening of the discharge nozzle was immersed in 1 L of still water for 1 minute, the blue absorbance of the water was measured, and the amount of chemical discharged from the chemical tank into 1 L of still water was calculated from the measured value. The result is shown in FIG.

From FIG. 11, when the narrowest flow path area of the chemical solution discharge nozzle is 28 mm ² , the chemical solution discharge speed from the chemical solution tank is increased by setting the chemical solution viscosity to 10 to 500 mPa · s, and the chemical solution viscosity is set to 500 to It can be seen that by setting the pressure to 2000 mPa · s, the chemical solution discharge speed is moderately suppressed.

(3) Relationship between the narrowest channel area of the chemical solution discharge nozzle and the discharge amount In order to investigate the relationship between the narrowest channel area of the chemical solution discharge nozzle and the discharge amount, the container A1 (the narrowest flow) prepared in (1) In addition to vessel area 28 mm ² (diameter 6 mm)) and container A 2 (narrowest channel area 0.8 mm ² (diameter 1 mm)), the narrowest channel area of the chemical discharge nozzle (without filter filling) is 3 mm ² ( A total of seven types of chemical solution discharge containers of diameter 2 mm), 7 mm ² (diameter 3 mm), 13 mm ² (diameter 4 mm), 38 mm ² (diameter 7 mm), and 50 mm ² (diameter 8 mm) were prepared. Further, a container A1-F1 (filling section length 10.5) filled with 5.5 mg of urethane foam (8 ± 2 cells / 25 mm) (Everlight MF-8, Bridgestone) in the chemical discharge nozzle of the container A1. 85mm, length of non-weighted part at the tip of the nozzle 2mm), and a container A1-F2 filled with urethane foam (number of cells 40 ± 4 / 25mm) (Everlight MF-40, Bridgestone) in the same way as the chemical discharge nozzle Was made.

  On the other hand, as shown in Table 3, two types of chemical solutions 3A and 3B were prepared, and these two types of chemical solutions 80g were mixed with seven types of containers in which the above chemical solution discharge nozzle was not filled with a filter and two types of filters. In the same manner as in (1), the tip opening of the chemical solution discharge nozzle is immersed in 1 L of still water for 1 minute, and the blue absorbance of the water is measured. From this, the amount of the chemical discharged from the chemical tank into 1 L of still water was calculated. The results are shown in FIG. 12 for seven types of containers in which the chemical liquid discharge nozzle is not filled with a filter.

From Figure 12, if the viscosity is of 500 mPa · s, by the narrowest flow area of the drug solution discharge nozzle and 13mm ² ~28mm ^2, the greater the solution discharge speed from the chemical liquid tank, also, the viscosity is 100mPa · in the case of s, by the narrowest flow area of the drug solution discharge nozzle and 7mm ² ~38mm ^2, it can be seen that the solution discharge speed from the chemical liquid tank is increased.
In addition, when the chemical solution discharge nozzle is filled with a filter (containers A1-F1, A1-F2), the chemical solution discharge amount is smaller than when the same chemical solution discharge nozzle is not filled with a filter (container A). The larger the number of urethane foam cells used, the smaller the discharge amount of the chemical solution. Therefore, it can be seen that the discharge amount can be adjusted depending on whether or not the filter is filled and the type of filter.
