Japanese Patent Laid-Open No. 2-229333 JP 2001-342665 A

  However, in the chemical solution discharge container shown in FIG. 1 of the above-mentioned Japanese Patent Application Laid-Open No. 2-229333 and the chemical solution discharge container of Japanese Patent Application Laid-Open No. 2001-342665, the water in which the drug is dissolved flows down or flows out to the hand-washing part. In addition, stains and pigments due to chemical components remain in the hand-washed area, and the appearance is likely to be damaged. In addition, in the chemical solution discharge container of FIG. 2 of JP-A-2-229333, although the tip of the permeation part is located in the low tank, the permeation part narrows the opening area of the drain of the hand-washing part. In addition, the water in which the drug is dissolved spreads over the hand-washed area, and stains tend to remain in the hand-washed area.

  Furthermore, the chemical solution discharge container disclosed in Japanese Patent Application Laid-Open No. 2001-342665 has a complicated structure and is expensive to manufacture.

  On the other hand, as shown in FIG. 7A, a simpler mechanism is composed of a chemical liquid tank 1 for storing the chemical liquid A and a cap 3 attached to the bottom opening 2 of the chemical liquid 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. 7B, this chemical solution discharge container 100x is placed on the drain outlet 21 of the hand-washing part 20 of the low tank, and flushing the water of the flush toilet as indicated by the arrow from the currant to the hand-washing part 20 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 without spreading to the hand washing portion. . 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 this chemical solution discharge container 100x, it is possible to mix the chemical solution A into the raw tank with a simple mechanism, and it is also possible to prevent the water in which the chemical is dissolved from spreading into the hand-washing part and making a stain there.

  However, as shown in FIG. 8, when the diameter of the drain port 21 of the hand-washing unit 20 is large, the tip opening 5 of the chemical solution discharge nozzle 4 is less likely to be splashed, so that the chemical solution may not be discharged. In addition, the water pressure and amount of water supplied from the curan are different depending on the installation situation of the toilet, and the positional relationship between the curan and the chemical solution discharge container is also different, so that the chemical solution discharge nozzle 4 is hardly washed with water and the chemical solution is not discharged. On the other hand, there are also situations where excessive discharge occurs.

  Therefore, the present invention is placed in the hand-washing portion of the low tank, and in the chemical solution discharge container that discharges the chemical solution by supplying water from the currant, the water in which the chemical solution is dissolved flows down into the row tank without accumulating in the hand-washing portion. It is an object of the present invention to provide a chemical solution discharge container with a simpler structure and at a low cost.

  The present inventor has found that a chemical liquid discharge nozzle provided below the chemical liquid tank is washed with water supplied from a currant and has a specific water passage rate near the tip of the chemical liquid discharge nozzle in a chemical liquid discharge container that discharges the chemical liquid. When this chemical solution discharge container is placed in the hand washing part of the low tank of the flush toilet, regardless of the size of the drain outlet, the water supplied from the currant hits the porous member and becomes porous. It has been found that the chemical solution is stably discharged because it flows through the surface and the inside of the material member, and the tip opening of the chemical solution discharge nozzle is washed. In addition, since this porous member allows water to pass through quickly, it does not greatly hinder the flow of water flowing into the drain port, and therefore, the water in which the chemical solution is dissolved does not spread to the hand washing part, thereby hand washing. It was found that the part can be prevented from being stained with a stain of the chemical solution.

  That is, the present invention comprises a chemical solution tank for storing a chemical solution, a chemical solution discharge nozzle provided below the chemical solution tank, and a porous member disposed in the vicinity of the tip opening of the chemical solution discharge nozzle. A chemical discharge container that is placed in a hand washing part of a low tank, the tip opening of the chemical discharge nozzle is washed with water supplied to the hand washing part, and the chemical liquid is discharged from the chemical tank through the chemical discharge nozzle, and is a porous member The chemical | medical solution discharge container whose water passage rate is 20%-95% is provided.

  The present invention also provides a toilet cleaning product in which the above-described chemical solution discharge container is filled with toilet cleaning liquid.

  The chemical solution discharge container of the present invention includes a chemical solution tank for storing a chemical solution, a chemical solution discharge nozzle provided below the chemical solution tank, and a porous member disposed near the tip of the chemical solution discharge nozzle, and has a simple structure. Therefore, it can be manufactured at low cost.

  In addition, the porous member used in the present invention is in the vicinity of the tip opening of the chemical solution discharge nozzle, is wider than the tip opening, and has a specific water permeability. For this reason, when the chemical solution discharge container of the present invention is used by being placed on the hand washing part of the low tank of the flush toilet, when water is supplied from the currant, the water hits the porous member and the surface of the porous member The tip opening of the chemical discharge nozzle is reliably washed with water induced by this porous member regardless of the size of the drain outlet of the hand-washing section, the water pressure, and the amount of water, The chemical solution is discharged stably.

  In addition, since the porous member used in the present invention has a specific water permeability, even if the porous member is located on the drain port of the hand-washing part or in the drain port, the flow of water flowing into the drain port is greatly hindered. The water in which the chemical solution is dissolved does not spread to the hand washing part. Therefore, it is possible to prevent the hand washing part from being soiled with a stain of the 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 partially cutaway cross-sectional view (a), a top view (b), and a bottom view (c) of a toilet cleaning product 200A filled with a chemical solution A in a chemical solution discharge container 100A of one embodiment of the present invention. FIG. 2 is a cross-sectional view of the toilet cleaning article 200A placed on the hand-washing portion of the low tank and water being supplied from the currant.

  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. On the bottom of the cap 3, a chemical solution discharge nozzle 4 and a foot 6 are formed integrally with the cap 3, and a holding member 12 for the porous member 11 is fixed. The holding member 12 includes an annular holding plate 12 a and a holding rod 12 b that suspends the holding plate 12 a from the cap 3, and the porous member 11 is held in the vicinity of the distal end opening 5 of the chemical liquid discharge nozzle 4 by the holding member 12. Has been.

  The chemical liquid tank 1 is filled with a chemical liquid A such as a toilet fragrance, a cleaning agent, and a disinfectant. As this chemical | medical solution A, a thing with a viscosity (20 degreeC) of 1-3000 mPa * s is used, Preferably the thing of 10-1000 mPa * s is used. This viscosity is a value measured with a B-type viscometer (60 rpm). 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. Can be discharged from the chemical solution discharge nozzle 4.

  Further, the chemical solution A is preferably one containing a colorant such as blue or green which is resistant to chlorine contained in tap water and safe for the human body. In this chemical solution discharge container 100A, the chemical solution A discharged from the chemical solution tank 1 and the water supplied from the currant are replaced, and the chemical solution in the chemical solution tank 1 may be diluted with water. By coloring, it is possible to observe from outside the chemical tank 1 how the color of the chemical liquid A in the chemical tank 1 changes due to dilution. Therefore, the chemical solution tank 1 is preferably made of a transparent or translucent material so that a change in color due to dilution of the chemical solution A can be observed from outside the chemical solution tank 1.

  It is preferable that the chemical | medical solution discharge nozzle 4 sets the aperture diameter of the front-end | tip opening part 5 to 0.5-10 mm. Thereby, the chemical | medical solution A is hold | maintained in the front-end | tip opening part 5 because surface tension and the inside of the chemical | medical solution tank 1 become a weak negative pressure. On the other hand, if the caliber is too small, the chemical solution A is difficult to be discharged, and if it is too large, the chemical solution A and the air are continuously replaced through the chemical solution discharge nozzle 4 while the water supply from the currant is stopped. Regardless of the presence or absence of the chemical solution A, the chemical solution A is quickly lost.

  The chemical solution discharge container 100A is characterized in that a porous member 11 is disposed in the vicinity of the tip opening 5 of the chemical solution discharge nozzle 4, and the porous member 11 has a specific water passage rate.

  Here, the porous member 11 is disposed in the vicinity of the front end opening 5 of the chemical solution discharge nozzle 4. Water is supplied from the currant, the water hits the porous member 11, and the surface of the porous member 11. It means that the tip opening 5 and the porous member 11 are arranged at a distance where the tip opening 5 comes into contact with water flowing on the porous member 11 when flowing inside. In this case, the distal end opening 5 of the chemical solution discharge nozzle 4 and the porous member 11 may be separated or in contact with each other. Furthermore, the tip opening 5 may be closed with the porous member 11. Even if the tip opening 5 of the chemical solution discharge nozzle 4 is blocked by the porous member 11, the porous member 11 used in the present invention has a water passage rate in a specific range and easily allows water to pass through. The discharge of the chemical liquid A from the chemical liquid discharge nozzle 4 is not hindered.

  Therefore, the distance between the tip opening 5 of the chemical solution discharge nozzle 4 and the porous member 11 is a distance that allows water flowing on the porous member 11 to contact the tip opening 5 of the chemical solution discharge nozzle 4, specifically. Is preferably 0 to 10 mm. When the tip opening 5 of the chemical solution discharge nozzle 4 and the porous member 11 are in contact with each other, the porous member 11 prevents water supplied from the currant from washing the tip opening 5 directly. Since the tip opening 5 is washed with water that has passed through the porous member 11, it is more preferable that the tip opening 5 of the chemical solution discharge nozzle 4 is not in contact with the porous member 11. For this, the porous member 11 having a high water passage rate is used. Even if the tip opening 5 of the chemical solution discharge nozzle 4 and the porous member 11 are in contact with each other, the chemical surface of the tip opening 5 is recessed from the edge of the tip opening 5 in an equilibrium state. Does not ooze into the porous member.

  The water passage rate of the porous member 11 is 20 to 95%, preferably 70 to 90%. If the water passage rate of the porous member 11 is too low, the flow of water supplied from the currant and flowing into the drain port 21 is obstructed, and the water in which the chemical solution is dissolved spreads in the hand washing unit 20, and the stain of the chemical solution is present in the hand washing unit 20. Since it becomes easy to stick, it is not preferable. Further, the flow of water supplied from the currant is limited to the surface of the porous member 11 having a low water passage rate, the flow inside the porous member 11 is reduced, the tip opening 5 of the chemical solution discharge nozzle 4 and the porous member. 11 is not preferable because the flow rate of water to the tip opening 5 decreases. On the contrary, if the water passage rate of the porous member 11 is too high, there is little water flowing on the surface of the porous member 11 when water is supplied from the currant, and the tip opening 5 of the chemical solution discharge nozzle 4 can be washed with the water. It becomes difficult. Therefore, even when water is supplied from the currant, the chemical A is washed out with water from the tip opening 5 and mixed into the low tank unless the water flowing down along the chemical discharge nozzle 4 directly hits the tip opening 5. No, the discharge amount of the chemical liquid A becomes unstable due to the size of the drain outlet, the water pressure and the amount of water, and the like.

  Here, the water passage rate is a value measured as follows. As shown in FIG. 9A, a funnel having an opening diameter D1 = 95 mm, a drain nozzle outer diameter D2 = 21 mm, a drain port 31 diameter D3 = 10 mm, a height L1 = 65 mm, and a drain nozzle portion height L2 = 22 mm. A test piece 32 having a diameter of 20 mm is fixed on the drainage port 31 of 30 as shown in FIG. 5B, and water is poured from the upper part of the funnel 30 so that the water injection height L3 = 60 mm is maintained. The amount of water passing through 31 is measured. On the other hand, without using the test piece 32, the amount of water passing through the drain port 31 in the same manner is measured, and the water passage rate (%) is obtained by the following equation (1).

[Equation 1]
Water passage rate (%) = ([Amount of water passing for one minute when there is a sample on the drain outlet) / [Amount of water passing for one minute when there is no sample on the drain outlet]) × 100 Formula (1)

  As a forming material of the porous member 11 having such a water passage rate, for example, a three-dimensional layer composed of an open-cell foam of a synthetic resin such as polyurethane, polyethylene, nylon, and melamine, a honeycomb-like, mesh-like, or net-like layer is used. Examples thereof include a woven fabric, a nonwoven fabric, and a metal fiber aggregate having a skeletal structure. Among these, open-cell urethane foam having 5 to 50 cells / 25 mm is preferable.

Further, the area of the surface of the porous member 11 facing the tip opening 5 of the chemical liquid discharge nozzle 4 can be adjusted even if the water supplied from the currant does not directly hit the tip opening 5 of the chemical liquid discharge nozzle 4. 11, it is preferable that the opening area of the tip opening 5 be larger than that of the tip opening 5 so that the tip opening 5 is reliably washed with water. Also, as shown in FIG. The diameter of the porous member 11 may be made smaller than the diameter of the drainage port 21 so that the porous member 11 can be inserted into the drainage port 21 when placed on the drainage port 21 of the hand-washing portion 20 of the hand-washed low tank. preferable. Specifically, the preferred size of the area of the porous member 11 varies depending on the diameter of the drain port 21, the length of the chemical solution discharge nozzle 4, and the like. Since it is about 6 cm, it is preferable that the area of the porous member 11 facing the tip opening 5 is 2 cm ² or less so that the tip opening 5 can be disposed also in a drain outlet having a narrow diameter.

  As shown in FIG. 2, when the chemical solution discharge container 100 </ b> A is placed on the drain port 21 of the hand-washing portion 20 of the hand-washed row tank of the flush toilet, the porous member 11 is disposed in the row tank below the drain port 21. The lengths of the holding rod 12b and the legs 6 of the porous member 11 are adjusted so as to be located inside. Therefore, in this chemical solution discharge container 100A, the porous member 11 does not impede the flow of water flowing into the drain port 21 not only from the point that the water passage rate is 20% or more but also from the installation position. The water in which the chemical solution A is dissolved does not accumulate in the hand washing unit 20 and immediately flows down into the low tank. Therefore, it is completely prevented that the hand-washing part 20 is stained with water in which the chemical solution A is dissolved.

  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.

  As a method of using the toilet cleaning product 200A, first, the chemical solution discharge container 100A is placed on the drain 21 of the hand-washing portion 20 of the low tank with hand-washing of the flush toilet while the chemical solution A is stored in the chemical tank 1. Then, the chemical solution discharge nozzle 4 is inserted into the drain 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.

  The case where a currant is provided on the drain outlet 21 of the hand-washing portion of the low tank and water is supplied from above the chemical tank 1 will be described below. When the chemical liquid discharge nozzle 4 is inserted into the mouth 21, this chemical liquid discharge container 100A 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 along the side surface of the chemical tank 1 to the hand-washing unit 20 and further flows into the drain port 21. Part of the water that has flowed into the drain port 21 flows so as to wash the tip opening 5 of the chemical solution discharge nozzle 4 directly, flows on the surface and inside of the porous member 11, and flows down into the raw tank. The other part flows into the hand-washing part 20 and then hits the porous member 11, and this water flows through and on the surface of the porous member 11 to wash the tip opening 5 of the chemical solution discharge nozzle 4, 11 flows through the surface and the inside of the tank and flows down into the low tank. 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, and the chemical solution A is mixed into the low tank.

  As described above, when the toilet cleaning product 200A is used, the water passage rate of the porous member 11 is 20% or more, so that the porous member 11 hinders the water flowing into the drain port and dissolves the chemical in the hand washing part 20. Water is prevented from spreading. Further, since the water passage rate of the porous member 11 is 95% or less, the water hitting the porous member 11 flows on the surface and inside thereof, and the tip opening 5 of the chemical solution discharge nozzle 4 is washed with this water. For this reason, as shown in FIG. 3, even if the water outlet 21 has a large diameter and the water flowing into the water outlet 21 has almost no water flowing so as to wash the tip opening 5 directly, it is porous. As long as the member 11 is sufficiently exposed to water, the chemical solution A can be reliably discharged regardless of the diameter of the drain outlet, the water pressure, the amount of water, and the like.

  The toilet cleaning product using the chemical solution discharge container of the present invention can take various other forms. For example, a recess may be formed on the surface of the porous member 11 that faces the tip opening 5 of the chemical liquid discharge nozzle 4 as in the toilet cleaning article 200B shown in FIG. Thereby, the water which hit the peripheral part of the porous member 11 can also be used effectively in order to wash the tip opening part 5.

  Further, as in the toilet cleaning product 200C shown in FIG. 5, the tip of the chemical solution discharge nozzle 4 is made longer by making the foot 6 longer than the toilet cleaning product 200A and shortening the chemical solution discharge nozzle 4 and the holding rod 12b. You may make it the opening part 5 and the porous member 11 become a substantially the same level as the formation position of the drain port 21. FIG. Depending on the type of low tank, a net or the like is stretched under the drain outlet to prevent items from falling from the drain outlet into the low tank, and the chemical discharge nozzle may not be inserted into the drain outlet. This toilet cleaning product 200C is also useful for a low tank.

  FIG. 6 is a side view (a), an enlarged view (b) of the vicinity of the porous member 11, and a bottom view (c) of a toilet cleaning product 200D according to the present invention.

  The chemical solution discharge container 100D of the toilet cleaning product 200D has a water guiding structure that causes water supplied from the currant to flow toward the chemical solution discharge nozzle 4 and flow down along the chemical solution discharge nozzle 4 with respect to the chemical solution discharge container A described above. As shown in the figure, eight plate-like portions 7 erected radially around the chemical solution discharge nozzle 4 are provided integrally with the cap 3 at the bottom portion of the cap 3, and the chemical solution discharge nozzle 4 is provided around the chemical solution discharge nozzle 4. Four water amount adjusting plates 8 extending to the vicinity of the front end opening 5 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 wash portion 20 of the low tank, the amount of water in the hand wash water, the water pressure, the placement position of the chemical solution discharge container 100D in the hand wash 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, it is possible to prevent the bottom surface of the cap 3 from blocking the drain port 21.

  By providing the water amount adjusting plate 8 around the chemical solution discharge nozzle 4, the water W from the currant continues to be excessively applied to the tip opening 5 of the chemical solution discharge nozzle 4 to prevent the chemical solution A from being excessively discharged. Can do.

  In addition, the aspect of the water induction structure and the water amount adjusting plate 8 is not limited to the above-described example. 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.

  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.

Examples 1-10, Comparative Examples 1-3
(Production of chemical discharge container)
In order to investigate the relationship between the diameter of the drain outlet of the low tank and the chemical discharge performance of the toilet cleaning product, first, the chemical discharge container 100A of FIG. 1 (chemical solution tank capacity 100 mL, diameter of the tip opening of the chemical discharge nozzle 2 mm) is prepared. did. In this case, as the porous member, an open-cell urethane foam having a diameter of 15 mm and a thickness of 5 mm (8 ± 2 cells / 25 mm) (Everlight MF-8, Bridgestone) is used with the tip opening of the chemical solution discharge nozzle. It was provided at a distance of 1 mm (Example 1). Moreover, the chemical | medical solution discharge container was similarly produced using the porous member of the material of Table 1 (Examples 2-10).

Further, a chemical solution discharge container of Comparative Example 1 was produced in the same manner as in Example 1 except that the porous member and the holding member for holding the porous member were not provided, and the same size polyethylene was used instead of the continuous urethane foam in Example 1. The chemical solution discharge container of Comparative Examples 2 and 3 was produced using the sintered body of No. 1 or pulp (850 g / m ² ).

(Evaluation)
The toilet cleaning products of Example 1 and Comparative Examples 1 and 2 were placed on a low tank with a drain port of 36 mm and a 16 mm low tank, respectively, and flushed with flush toilet water every 2 minutes ( The number of times that the concentration of the chemical solution was diluted to 5% of the initial value and was stably discharged until the end of the drug effect was examined by measuring the visual and absorbance (630 nm) at room temperature 25 ° C. and water temperature 23 ° C.). The results are shown in Table 3.

[Table 3]

  From the results of Table 3, according to the toilet cleaning products of Examples 1 to 10 in which the water passage rate of the porous member is in the range of 20 to 95%, the discharge of the chemical liquid is performed regardless of the diameter of the drain outlet of the hand-washing portion of the low tank. However, according to the toilet cleaning product of Comparative Example 1 without the porous member, the discharge of the chemical liquid becomes unstable when the drain port is large, According to Comparative Example 2 in which the water passage rate with the porous member is 4.4% and Comparative Example 3 in which the water passage rate is 0.1%, the water in which the chemical solution is dissolved is washed by hand when the diameter of the drainage port is small. It was confirmed that the hand-washing part was easily soiled. In Comparative Example 2 and Comparative Example 3, the number of times 717 times and 765 times is large because the distance between the tip opening of the chemical solution discharge nozzle and the porous member (sintered body, pulp) is short, and the sintered body This is considered to be because the flow rate of water from the currant is limited to a slight flow path of 1 mm between the tip opening of the chemical solution discharge nozzle and the porous member. On the other hand, urethane foam having a high water passage rate is considered to increase the discharge amount because water from the currant can be guided freely from around the urethane.

  The toilet cleaning product using the chemical solution discharge container of the present invention can be used for a low tank with hand-washing in a flush toilet regardless of the position of the currant or drain outlet, the size of the drain outlet, etc. in the hand-washing section.
