  Hereinafter, actual forms of the present invention will be described with reference to the accompanying drawings. In addition, in each drawing, the same code | symbol is attached | subjected to the same component and the repeated description is abbreviate | omitted.

  FIG. 1 is a side view of a medicine supply device according to an embodiment of the present invention. The medicine supply tool 1 includes a bowl-shaped supply tool body 10 that can accommodate a columnar solid medicine 50 and a lid body 4 that covers the upper side of the supply tool body 10.

  The supply tool main body 10 is formed in a horizontally long shape, and includes engaging portions 6 and 6 on both sides in the longitudinal direction of the upper edge, and the protrusions 4a and 4a provided on the lower edge of the lid 4 are connected to the engaging portions 6 and 6, respectively. 6, the lid 4 is detachably attached to the supply tool body 10. A window portion 8 extending in the circumferential direction is formed on the upper portion of the supply tool body 10 so that the fragrance component of the solid medicine 50 can be evaporated and the remaining amount of the solid medicine 50 can be confirmed. A discharge port 12 is formed at the center of the bottom of the supply tool body 10, and a plurality of legs 13, 13 are provided so as to protrude downward from the periphery of the discharge port 12.

  The lid 4 can be composed of synthetic resin, earthenware, glass, or the like. In the present embodiment, the lid 4 has no opening so that the solid medicine 50 is not directly exposed to water. One or more volatilization ports may be formed.

  2 is a plan view of the supply tool body 10, and FIGS. 3 and 4 are perspective views of the supply tool body 10 as viewed from above and below, respectively. The supply tool body 10 is provided with reinforcing ribs 11 along the longitudinal direction of the inner surface. Further, a plurality of water conduits 14 and 14 extending radially from the discharge port 12 are formed inside the supply tool main body 10, and the water intakes are individually provided outside the water conduits 14 and 14. 15 and 15 are provided. In the present embodiment, intake ports 15 are formed at equal intervals in a total of six locations including both longitudinal sides of the supply tool body 10.

  The water conduit 14 is formed in a V-shaped cross section, and is inclined downward from the water intake 15 toward the outlet 12. The lower center of the water intake 15 protrudes downward in a V shape according to the shape of the water conduit 14. Each intake port 15 has the same shape, but is provided with a shielding piece 15b that covers the upper part of the opening except for those formed on both sides in the longitudinal direction of the supply tool body 10, whereby the supply tool The total opening area of the intake ports 15 formed at other positions is set smaller than the total opening area of the intake ports 15 formed on both sides in the longitudinal direction of the main body 10.

  The water conduits 14 and 14 are partitioned by a pedestal portion 16, and the bottom surface of the solid medicine 50 is supported by each pedestal portion 16. The pedestal portion 16 includes a notch groove-shaped communication path 17 that communicates between the water guide paths 14 and 14 adjacent to each other on both sides in the circumferential direction. The depth from the upper surface of the base part 16 to the bottom part of the communication path 17 is, for example, 4 mm at the deepest part and 2 mm at the shallowest part. If the depth is too shallow, the effect of providing the communication passage 17 is unlikely to occur. On the other hand, if the depth is too deep, the passing water is difficult to come into contact with the solid medicine 50, and is preferably 1 mm to 7 mm.

  An auxiliary port 18 that faces the communication channel 17 from the outside is formed at a radially inner position than the water intake port 15 on the outer side in the radial direction of the communication channel 17 in the pedestal portion 16. Further, an auxiliary discharge portion 19 penetrating in the vertical direction with the peripheral edge side of the discharge port 12 cut away is formed on the inner side in the radial direction of the communication passage 17 in the pedestal portion 16.

  As described above, since the water conduit 14 has a V-shaped cross section, an upward slope is formed from the water conduit 14 to the communication passage 17. Due to this inclination, the water taken in from the water intake 15 is quantitatively guided to the communication path 17, so that uniform dissolution of the solid medicine 50 can be promoted. The configuration of the communication portion 17 may be, for example, a through hole or a pipe shape in addition to the groove shape.

  Each water guide channel 14 and the pedestal portion 16 are surrounded by a ring-shaped impermeable wall 20 having an inner diameter slightly larger than the diameter of the solid medicine 50 to be accommodated. A dewatering port 21 is formed outside the impermeable wall 20 at a position corresponding to each pedestal portion 16. In addition, a slit 22 is formed in the upper end portion of the water shielding wall 20 at a position corresponding to each dewatering port 21.

  The ratio of the total area occupied by the communication passage 17 in the region surrounded by the impermeable wall 20 is preferably 2% or more and 80% or less, and more preferably 10% or more and 30% or less in plan view. By setting the ratio to at least 2% or more, sufficient water contact with the solid medicine 50 is possible while water is distributed through the communication path 17, and uniform elution on the bottom surface of the medicine can be promoted.

  In the medicine supply device 1 configured as described above, the bottom of the solid medicine 50 is supported by the pedestals 16 and 16 by housing the solid medicine 50 in the water shielding wall 20 of the supply body 10. And in the state which closed the cover body 4, as shown in FIG. 1, by inserting the leg parts 13 and 13 in the flow-down opening 54 formed in the water receiving tray 52 of the water tank for flush toilets, in the water intake 15 The peripheral edge of the protrusion 15 a comes into contact with the upper surface of the water supply tray 52, and the medicine supply tool 1 is placed on the upper surface of the water supply tray 52. When the shape of the water supply tray 52 is a general rectangular shape, the supply tool body 10 can be placed so that the longitudinal direction of the supply tool body 10 coincides with the longitudinal direction of the water supply tray 52.

  Water supplied from a faucet (not shown) to the water supply tray 52 is mainly introduced into the supply tool main body 10 from each water intake 15, and passes through each water conduit 14 and the communication passage 17 to the pedestal portion 16. It contacts the bottom surface of the supported solid medicine 50 and is discharged from the discharge port 12. Thus, since the medicine supply tool 1 has the communication passage 17 in addition to the water conduit 14, it can obtain a wide contact area with the solid medicine 50 and can sufficiently dissolve the medicine immediately after the start of use. . In addition, when the water intake amount at some of the water intakes 15 is small, when water can be taken only from a specific water intake 15, when a part of the solid medicine 50 collapses during use and a part of the water conduit 14 is blocked In such a case, the water can be easily distributed between the water conduits 14 and 14 via the communication passage 17, and the elution of the medicine can be stabilized.

  The elution of the drug from the solid drug 50 is performed substantially uniformly only from the bottom surface mainly by contact with water passing through the water conduit 14 and the communication path 17. Therefore, by making the solid medicine 50 into a columnar shape as in the present embodiment, the solid medicine 50 can be reduced in volume while maintaining the initial diameter, and the solid medicine 50 is kept in the pedestal portion 16 until the end of use. It can be supported stably. As long as the shape of the solid medicine 50 is not limited to a columnar shape but a rectangular cross-section such as a prismatic shape, the volume can be reduced while the cross-section is kept constant, so that the same effect as described above can be obtained. be able to.

  Further, the shape of the solid medicine 50 may be other shapes such as a cone shape, a truncated cone shape, a spherical shape, etc., in addition to the above-described one having a constant cross section. When the water passing through the water contacts the bottom surface of the solid medicine 50 substantially uniformly, the solid medicine 50 can be dissolved while the bottom shape remains substantially constant.

  Moreover, the solid medicine 50 is not limited to a structure having only one layer, and a structure composed of a plurality of layers can be preferably used. For example, as shown in FIG. 8 (a), the periphery of the center layer is 1 such as a ring-shaped outer layer 50b concentrically arranged at a weight ratio of 1: 3 around the columnar center layer 50a. By using what is composed of a plurality of layers covered with an outer layer equal to or higher than the layers, it is possible to maintain the ratio of active ingredients and pigments eluted from each layer at a desired value in combination with the above effects. . Examples of the solid drug having such a structure include a kneading molding method disclosed in JP 2000-109897, a melt manufacturing method in which components are melted and mixed with heat, filled into a mold, and the drug is extracted from the mold after cooling. Can be manufactured.

  As the central layer constituting the solid drug, surfactants, inorganic sulfates, active ingredients (water repellent, hydrophilizing agent, antifouling agent, deodorant, flavoring agent, antibacterial agent, antibacterial agent, bactericide 1 or 2 or more of chelating agents, enzymes, coloring agents, etc.), and examples of the outer layer mainly include surfactants, pigments, fragrances, anhydrous sulfates, etc. be able to. In the configuration of the solid medicine 50 having a plurality of layers, in addition to the above, for example, as shown in FIG. As shown in FIG. 8 (c), a cylindrical layer 50f filled with cylindrical layers 50g, 50h, and 50i having a smaller diameter than this, as shown in FIG. 8 (d), The layers 50j, 50k, and 50l are stacked in the vertical direction, and after the entire lower layer 50j is dissolved, the layers 50k and 50l adjacent to the upper side are sequentially dissolved. In addition, each layer which adjoins in each said structure should just differ in the kind and ratio about one or more components among the 1 or several component to contain.

  Moreover, the supply tool main body 10 is formed in a horizontally long shape so that the total opening area of the intake ports 15 formed at other positions is smaller than the total opening area of the intake ports 15 formed on both sides in the longitudinal direction. Therefore, when placed on the most common rectangular water supply tray 52, regardless of the water flow from the water supply faucet, the shape or gradient of the water supply tray 52, etc. Water can be introduced uniformly, and sufficient and stable elution of the drug can be promoted. In the present embodiment, the supply tool body 10 is configured to be horizontally long so that the water intakes 15 having a large opening area are naturally positioned on both sides in the longitudinal direction of the water supply tray 52 when placed on the water supply tray 52. Although it comprises, the supply tool main body 10 does not necessarily need to be horizontally long, and the water intake 15 with a large opening area is the longitudinal direction of the water supply tray 52 also by setting suitably the shape of the cover body 4, arrangement | positioning of a handle | pattern, etc. The user can be prompted to be located on both sides of the direction.

  Furthermore, since the water intake 15 is formed such that the lower center protrudes downward, the contact area with the water supply tray 52 is small, and the medicine supply tool 1 can be placed in an accurate posture. Even when the amount of water flowing through the outer surface of the medicine supply tool 1 is small, the water supplied to the water supply tray 52 can be reliably introduced into the supply tool body 10. Excess water that is not introduced into the medicine supply tool 1 passes between the lower surface of the supply tool main body 10 and the water supply tray 52 and flows down into the tank from the flow-down port 54.

  In addition, since the auxiliary port 18 that faces the communication path 17 is formed in the pedestal portion 16, it is possible to adjust the flow rate of water passing through the communication path 17 by taking in and out water through the auxiliary port 18. From this point, the drug can be sufficiently and stably eluted. The water introduction from the auxiliary port 18 also functions as priming water for water flowing into the communication passage 17 from the water supply passage 14 and has an effect of promoting smooth water introduction to the communication passage 17.

  The water that has entered from the window portion 8 of the supply tool body 10 is blocked by the impermeable wall 20 and flows out from the dewatering port 21. Further, when an excessive amount of water is introduced from the intake port 15, the excess water flows out from the dehydration port 21 through the slit 22. Therefore, even in such a case, water does not accumulate in the impermeable wall 20 excessively.

  As mentioned above, although one Embodiment of this invention was explained in full detail, the specific aspect of this invention is not limited to the said embodiment. For example, in the present embodiment, a plurality of water intakes 15 are provided for each water conduit 14, but it is not always necessary to individually correspond to the water conduits 14, and a plurality of water conduits are introduced after water is introduced from the water intake 15. 14 and 14 may be distributed. Moreover, the shielding piece 15b provided in some water intakes 15 is not necessarily required.

  In the present embodiment, the communication passage 17 is formed in a groove shape at a substantially central position in the radial direction of the pedestal portion 16, and the pedestal portion 16 is left with the same width inside and outside the communication passage 17. However, as long as the water introduced from the water intake 15 is distributed to each water conduit 14 and the passing water can be in contact with the bottom surface of the solid medicine 50 in the initial use, it may be in other arrangements and shapes. Good.

  Moreover, the attachment structure of the lid 4 in the supply tool body 10 can have various aspects other than the present embodiment. For example, as shown in FIG. 106 and 106 can be provided, and the engagement protrusions 106 and 106 can be engaged with engagement grooves formed along the periphery of the lower portion of the lid made of ceramic or the like.

  Moreover, in this embodiment, the shape part which protrudes below from the lower center of the water intake 15 comprises the protrusion part 15a by forming the water conduit 14 in V-shaped cross section, but this protrusion part 15a As shown in FIGS. 9 and 10, it may be constituted by a projecting piece or the like provided in the vicinity of the lower portion of each water intake 15. The protruding length of the protruding portion 15a downward is not particularly limited, but is about 1 mm, for example. Although it is preferable that there are a plurality of projecting portions 15a, it is not always necessary to provide all of the water intakes 15. Thus, by providing the protrusion 15a in the vicinity of the lower portion of the water intake 15, a water passage space can be secured between the water intake 15 and the water receiving tray 52, and immersion of the water intake 15 can be prevented. Can do. When the projecting portion 15a is constituted by a projecting piece, the shape of the water intake 15 may be a general rectangular shape.

  Further, in the configuration shown in FIGS. 9 and 10, a strip-like support portion 10 a is provided on the outer surface of the supply tool body 10. The support portion 10a can be provided at an arbitrary position in a region existing radially outward from the water intake port 15 with the discharge port 12 as a center, and thereby, the gradient of the water supply tray 52 is steep and the protruding portion 15a. Even when the water supply tray 52 cannot contact the water supply tray 52 or when the entire protrusion 15a is accommodated in the flow-down port 54 due to the large diameter of the flow-down port 54, the supply tool body 10 and the water supply tray 52 A space can be secured between the water intake port 15 and a water flow path to the water intake port 15, and a clearance between the bottom surface of the supply tool body 10 and the water supply tray 52 can be secured, so Smooth drainage can be performed. The position of the support portion 10a is more preferably a position that does not hinder the water conveyance from the water intake port 15. In FIG. 9, the four support portions 10a are distributed in the vicinity of the periphery of the different dewatering ports 21, respectively.

  If the length of the support portion 10a is too long, the protruding portion 15a may not function effectively. Therefore, the solid medicine 50 in the supply tool body 10 is supported horizontally (that is, a side view shown in FIG. 9). In this state, the lower end of the support portion 10a is preferably located above the lower end of the protrusion 15a. Thereby, the supply tool main body 10 can be easily installed along the curved surface of the water supply tray 52. An example of the length of the support portion 10a is about 4 mm.

  As described above, in the configuration in which the supply tool body 10 includes the projecting portion 15a and the support portion 10a, the shape of the water supply tray 52 on which the medicine supply device 1 is placed, the amount of water supplied to the water supply tray 52, and the like. In addition, water can be stably introduced from the respective water intakes 15 to the inside of the supply tool main body 10, and uniform elution on the bottom surface of the medicine can be further ensured.

  That is, when the gradient of the water supply tray 52 is steep, the lower end of the support portion 10a comes into contact with the upper surface of the water supply tray 52 at a height H as shown in FIG. And a water supply tray 52 can be secured. Therefore, there is no possibility that the side surface of the supply tool main body 10 is in close contact with the water supply tray 52, and the water supplied to the water supply tray 52 can be reliably introduced into the supply tool main body 10 from the water intake 15.

  On the other hand, when the gradient of the water supply tray 52 is gentle, as shown in FIG. 9 (b), the lower end of the projecting portion 15 a comes into contact with the upper surface of the water supply tray 52, and the bottom surface of the supply tool body 10 and the water supply tray 52. A gap can be secured between the two. Therefore, there is no possibility that the bottom surface of the supply tool body 10 will block the flow-down port 54, and it is possible to reliably prevent water from accumulating in the water supply tray 52 and taking in more water than necessary from the water intake port 15.

  Hereinafter, based on an Example and a comparative example, this invention is demonstrated still in detail. However, the present invention is not limited to the following examples.

As an example, the drug supply device having the configuration shown in FIG. 1 contains a solid drug used for “Bluelet Pottery (only Suzuran fragrance)” manufactured by Kobayashi Pharmaceutical Co., Ltd. The product was placed on a water supply tray of model number: S721B) and flushed with “Large” once an hour (water temperature: 25 ° C., air temperature: 25 ° C.). And the stored water of the water storage tank into which the water which passed the chemical | medical agent supply tool in each time flowed was extract | collected to the test tube, and the light absorbency in wavelength 630nm was measured with the spectrophotometer (Shimadzu Corporation, model number: UV-1700). The result is shown in FIG. FIG. 6A shows a value obtained by multiplying each absorbance of N = 3 by 1000. Moreover, the used solid medicine has a two-layer structure, and the components and the like are as follows.
(Solid drug used)
Outer layer: perfume, surfactant, pigment, enzyme, chelating agent, green tea extract inner layer: surfactant, pigment, chelating agent content: 25 g (outer layer: inner layer = 3: 1)
Water color: Blue Absorbance × 1000 value is in the range of 50 to 110, which is the best color. As is clear from FIG. 6 (a), the results of the examples show that color development is good immediately after the start of use and that stable color development is obtained throughout the use period.

  Next, the same test as described above was performed using various water storage tanks on which the medicine supply tool was placed, and the absorbance (× 1000) of water collected after the 20th flush was measured. The result is shown in FIG. As is clear from FIG. 6 (b), in the example, for any of the water tanks tested, a good color was obtained immediately after the initial use.

  On the other hand, as a comparative example, a container having a configuration disclosed in Japanese Patent Application Laid-Open No. 2004-316417 (specifically, a configuration in which the lid shown in FIG. 14 of the publication and the supply tool main body shown in FIG. 16 are combined). The same test as described above was performed using the same solid drug as in the example. The results are shown in FIGS. 7 (a) and (b).

  As is clear from FIG. 7 (a), the initial color development was not particularly sufficient for the comparative example, and this result was the same for other water storage tanks as shown in FIG. 7 (b). In addition, as compared with the examples, the coloration stability over the entire use period was also inferior.

  Note that the amount of water supplied to the water receiving tray of each water storage tank is as shown in FIG. 6B as a value for 10 seconds, and water is actually supplied to the water receiving tray for 60 seconds. That is, the total amount of water supplied to the water tray is six times the value shown in FIG.

  Next, in order to confirm the effect of providing the protruding portion 15a and the support portion 10a on the supply tool body 10, the above-described drug supply tool having the configuration shown in FIG. 1 and the drug supply tool having the configuration shown in FIG. Similarly to the above, the absorbance of water collected after 20 flashes was measured, and the state of water being introduced from the water intake 15 was observed. As the water storage tank, model number S771B manufactured by Totoki Equipment Co., Ltd. was used. In this water supply tank, the amount of water supplied to the water receiving tray is normally 500 mL / 10 sec. However, in this example, since the test is performed under more severe conditions, the amount of water supplied to the water receiving tray is 750 mL. / 10 sec and 800 mL / 10 sec were respectively tested. The result is shown in FIG.

  As apparent from the absorbance in FIG. 11, when the amount of water supplied to the water tray is increased, the configuration shown in FIG. 9 can suppress an increase in the coloration of the drug compared to the configuration in FIG. 1. Recognize. When observing how water is introduced from the water intake 15, in the configuration of FIG. 1, the gap formed between the bottom surface of the supply tool body 10 and the top surface of the water supply tray 52 is very small. The amount of water supplied to the water supply tray 52 is larger than that during normal use, so that the amount of water supplied to the water supply tray 52 is larger than the amount discharged from the downflow port 54. In the state of the side view of FIG. 1, the upper part of the water intake 15 is only slightly exposed from the water surface, and most of the water intake 15 is submerged.

  On the other hand, in the structure of FIG. 9, even if the supply amount to the water supply tray 52 is so large that it cannot occur in a normal use state, the lower end of the protrusion 15a contacts the upper surface of the water supply tray 52. Since the surplus water can sufficiently pass between the bottom surface of the supply tool body 10 and the upper surface of the water supply tray 52, an appropriate amount of water is continuously introduced from each intake port 15. It was estimated that water was properly distributed through each water conduit 14.
