Kit

The present invention relates to a kit for mounting on a wall surface of a urinal, and discharging the washing liquid or other sputum to the toilet side every time it is rinsed with washing water along the wall surface.

For example, there is known a container body having a container body attached to a wall surface of a urinal and having an inlet port for drawing the washing water flowing upward from the wall surface to the inside. The main body is provided with a medicine storage unit for storing the medicine which is dissolved in the washing water drawn into the inside of the container body to generate the sputum, and an outlet for discharging the generated sputum is formed in the lower portion of the container body (for example, refer to the patent) Document 1).

In the cartridge, the washing water flowing down the wall surface of the urinal is introduced into the drug cartridge, but when a predetermined amount of the washing water is introduced into the drug cartridge, the washing water introduced later is washed with water. The state is discharged to the outside of the drug cartridge, and when the washing water is no longer introduced into the drug cartridge under the stop flow of the washing water, the drug solution generated in the drug cartridge is discharged from the gas outlet.

Patent Document 1: Japanese Laid-Open Patent Publication No. 2003-247256 (Fig. 2, Fig. 3)

In the above-described conventional drug cartridge, the chemical liquid hardly flows out while the washing water is introduced into the drug cartridge, and after the introduction of the washing water is stopped, the high-concentration drug solution in the drug cartridge flows out to the lower portion of the drug cartridge. However, in this manner, the liquid medicine cannot be brought into contact with the entire wall surface of the urinal, and the urinal washing cannot be performed with good efficiency.

Therefore, in view of the above problems, an object of the present invention is to provide a drug cartridge capable of eliminating the above disadvantages.

In order to solve the above problems, the chemical cartridge of the present invention has a box shape and is mounted on a wall surface through which the washing water of the urinal flows, and is washed on the upper surface of the surface facing the wall (hereinafter referred to as "back surface"). Water is introduced into the introduction port in the drug cartridge, and has an outflow port at a lower portion of the back surface, and a drug is stored in the drug cartridge, and a part of the washing water at the time of washing is introduced from the introduction port to flow the drug to the drug. Dissolving to generate a chemical solution, and causing the generated chemical liquid to continue to flow from the outflow port to the wall surface of the urinal after washing, wherein the upper portion of the outflow opening has a discharge opening having an opening area larger than the outflow opening, when During the introduction of the washing water, the overflow portion of the generated chemical liquid flows out from the drain port to the wall surface of the urinal.

When a large amount of the washing water is introduced into the chemical cartridge, the introduced washing water is not directly discharged as the washing water, but is discharged after contacting the medicine as a chemical liquid. With such a configuration, although the concentration is somewhat lowered, a large amount of chemical liquid can be discharged.

Further, basically, the height of the lower edge of the drain port is made uniform to the height of the upper edge of the chemical in the initial state before use. When the amount of introduction of the washing water is large, the drain flows from a position higher than the lower edge of the drain port. Therefore, by setting the height of the lower edge of the drain port to be lower than the upper edge of the medicine in the state after the storage, it is possible to achieve the flushing of the introduction amount and the displacement amount in the state where the washing water is continuously introduced.

In addition, if the amount of the liquid medicine from the drain port is large, the liquid medicine is expanded to the left and right along the wall surface of the urinal by the amount of the water discharge (the left and right sides of the drug cartridge 1 are observed from the user of the urinal). It is preferably expanded to the left and right, preferably on the back side of the drug cartridge (from the back side of the urinary device to the back side of the cartridge 1), and a mountain-shaped drain groove for diverting the liquid medicine discharged from the drain port to the right and left.

Further, when the drain groove is provided in this way, if the front end of the drain groove protrudes from the side surface of the drug cartridge and the outflow direction adjusting portion is provided so that the direction of the chemical liquid flowing out from the tip end faces the wall surface side of the urinal, The liquid can be surely passed from the drain to the wall of the urinal.

In order to allow the introduced washing water to flow efficiently to the drug, a separator for biasing the drug on the front side may be provided in the drug cartridge, and a cleaning device may be formed on the left and right sides of the separator for introduction from the inlet. The opening for the washing water flowing to the medicine side and the opening for the chemical liquid for discharging the washing water generated after the contact with the medicine to the drain port are formed in the center of the partition.

Similarly, it is preferable to provide a crotch portion on the upper portion of the opening for the chemical liquid to alleviate the flow of the washing water introduced from the introduction port without impeding the flow of the washing water.

Further, when a partition for preventing the washing water from being mixed with the chemical liquid is provided between the opening for the washing water and the opening for the chemical liquid, the concentration of the chemical liquid to be drained can be prevented from being lowered.

Further, a wall portion for preventing the leakage of the chemical liquid toward the rear and guiding the left and right wall portions may be formed at the rear edge of the drain groove.

Furthermore, if the liquid medicine does not flow in the drain tank after the drainage of the chemical liquid from the drain port is stopped, the liquid medicine cannot be continuously expanded to the left and right. Therefore, it is preferable to form an auxiliary drain port on the upper portion of the drain tank for continuously discharging the liquid medicine in the medicine tank to the drain tank after the liquid medicine from the drain port is stopped.

Moreover, a cover portion that covers the medicine from above is provided to cover a part of the medicine, and when the washing water is introduced, air is left inside to prevent the washing water from entering the inside of the lid, and the washing water is prevented from contacting the covered portion. The drug can inhibit the dissolution rate of the drug.

Moreover, the present invention provides a pharmaceutical composition comprising a solid drug of the above-described drug cartridge and a molded body of a solid acid.

According to the above description, when the introduced washing water is discharged as a chemical liquid, the overflow portion is overflowed by the washing water during the period in which the washing water is introduced into the chemical cartridge. The washing water is a chemical liquid, and a large amount of the chemical liquid can be caused to flow to the wall surface of the urinal by discharging from a drain opening having a large opening area different from the usual outlet. Further, since there is no overflow portion after the completion of the washing, the chemical liquid is not discharged from the drain port and continues to be discharged from the normal outlet. As a result, the chemical solution can be brought into contact with a wide range of the wall surface of the urinal, and the disinfection or washing using the chemical solution can be performed efficiently.

Referring to Fig. 1, a kit according to the present invention is attached to a wall cartridge of a urinal W, and is suspended from a urinal W through a handle 11. As shown in Fig. 2, the urinal W has two types of cockroaches, one of which is shown in (a), the shower outlet WH, which is called washing water, is mostly in the shape of a shower, and the other, as shown in (b), is called only The sprinkler shape of the discharge port WH is set at the center. Since the shower is provided with a plurality of discharge ports WH, the discharge speed of the washing water is slow. On the other hand, the spreader shape is configured such that the washing water is strongly discharged due to the small number of discharge ports, and the washing water flows to the entire urinal W. The kit 1 of the present invention can be installed in any form of urinal. Specifically, a metal hook H is hung on the discharge port WH, and the handle 11 is hung on the hook H.

In Fig. 2(a), hooks are provided at the two discharge ports, so that the two introduction ports are immediately below the discharge port of the washing water, and the washing water can be efficiently introduced. Further, since the hook H is a structure that is inclined to the front, the flow of the washed washing water does not hit the hook and spread. Further, since the hook of Fig. 2(b) is pulled downward by the hanging of the medicine cartridge, the sprayed water is diffused without hitting the hook.

Referring to Figs. 3 and 4, the drug cartridge 1 is composed of a cartridge body 2 and a lid portion 3.

The engaging portion 21 that the handle 11 is slidably engaged with the left and right side surfaces of the cartridge body 2 is formed. In addition, a pair of right and left inlets 4 are provided on the upper surface of the wall surface of the urinal W in a state of being attached to the urinal W. The washing water Wa is introduced into the cartridge main body 2 from the two introduction ports 4, and the inside of the medicine C to be described later is dissolved in the chemical solution Wf, and flows out from the three outlets 51 provided in the lower portion of the back surface. Further, in order to allow the chemical solution Wf flowing out from the outflow port 51 to flow to the wall surface of the urinal W, the guide 5 is formed at the lower portion of the center outlet port 51. Although the guide inlet 4 is provided on the left and right in FIGS. 3 and 4, the present invention is not limited thereto, and may be one elongated opening or three or more small openings, and the position thereof may not be left or right. Central or close to the center. In short, any position can be used as long as the washing water Wa can be smoothly introduced into the inside of the drug cartridge.

The inlet port 4 and the three points of the guide 5 are in contact with the wall surface of the urinal W to maintain the posture of the medicine cartridge 1. Further, the sub-guides 52 are provided at the right and left outlets 51, respectively, and the chemical liquid is also caused to flow to the wall surface of the urinal W.

A drain port 7 is formed in a central portion of the inlet port 4. In the first embodiment shown in FIG. 3, the lower edge of the drain port 7 is set to be the same height as the upper edge of the medicine C accommodated in the cartridge body 2 as will be described later.

Guide members 22 are formed on the left and right inner side surfaces of the cartridge body 2, respectively. On the other hand, the partition wall 6 which extends downward is formed in the cover part 3. Although the partition wall 6 is engaged with the guide 22 and housed in the cartridge main body 2, the medicine C accommodated therein is set so as to be located on the front side of the partition wall 6. Further, an opening 61 for washing water is formed on the right and left sides of the partition wall 6, and the introduced washing water Wa flows through the opening 61 to the medicine side. Moreover, the inflowing washing water Wa contacts the medicine C as the chemical liquid Wf, but the opening 62 through which the chemical liquid Wf passes is provided in the center of the partition wall 6. Therefore, the chemical liquid Wf flowing from the front to the rear through the opening 62 is drained from the drain port 7 to the outside.

Further, the urinal W washing water Wa, which is particularly in the form of a spreader, is strongly introduced into the cartridge body 2 from the introduction port 4. Here, the crotch portions 61a and 62a are formed on the upper portions of the respective openings 61 and 62 in order to alleviate the flow.

Fig. 5 shows a second embodiment, and the difference from the embodiment 1 shown in Fig. 3 is the height of the lower edge of the drain port 7. As described above, in the first embodiment shown in Fig. 3, the lower edge of the drain port 7 is substantially the same height as the upper edge of the drug C, but in the second embodiment shown in Fig. 5, the lower edge of the drain port 7 is lowered. 5mm.

Next, in the third embodiment shown in Fig. 6, the height of the lower edge of the drain port 7 is the same as that of the first embodiment, but a mountain-shaped drain groove 8 is formed at the lower portion of the drain port 7. The front end 82 of the drain groove 8 is disposed to protrude outward from the side of the cartridge body 2. Further, an outflow direction adjusting portion 81 is provided for bending the direction of the chemical solution flowing out from the distal end 82 to the wall surface side of the urinal W. The outflow direction adjusting portion 81 is formed to be inclined at an angle α to the rear.

In the fourth embodiment shown in Fig. 7, the drain groove 8 of the third embodiment of Fig. 6 is added to the second embodiment shown in Fig. 5.

In the fifth embodiment shown in Fig. 8, the crotch portion 61a is further removed in the fourth embodiment, leaving only the crotch portion 62a.

In the embodiment 6 shown in FIG. 9, a partition plate 63 is provided for the embodiment 5 shown in FIG. 8 for partitioning the opening 61 and the opening 62.

In the embodiment 7 shown in Fig. 10, in the fourth embodiment shown in Fig. 7, the vertical wall 83 is provided at the rear of the drain groove 8.

Next, in the eighth embodiment shown in Fig. 11, as in the fourth embodiment shown in Fig. 7, the auxiliary drain port 84 is provided on the upper portion of the drain groove 8.

The above-described cartridges shown in Examples 1 to 8 were attached to the urinal W, and the washing water was actually flowed, and the concentration of the chemical solution was measured. Further, all of the three outlets 51 are circular with a diameter of 1.5 mm, and the flow rate of the chemical solution flowing out from the outflow port is slow, so that it flows out from the outlet port as compared with the amount of the chemical liquid flowing out from the outflow port 7. The amount of liquid medicine is small. However, since the chemical liquid remaining in the drug cartridge after the washing water stops is discharged from the outflow port 51, the chemical liquid is not diluted and discharged by the washing water, and flows into the drain gate of the lower portion of the toilet. Therefore, it is possible to form a structure capable of effectively cleaning the dirt at the center portion of the wall surface of the toilet and the drain gate which are likely to cause fouling.

Specifically, the drug C is formed into a wall-shaped urinal (U370) manufactured by TOTO Co., Ltd., which is formed into a shower-shaped urinal W, by forming 27 g of the solid acid into a size of 25 mm in length, 52 mm in width, and 17 mm in height. The washing water was flowed at intervals of 10 minutes for 10 seconds. Then, 18 hours after the installation, the sluice water of the toilet was taken, and the washing liquid of the lower portion of the container (寛60 mm) and the left side of the container (寛60 mm) between the washing water and the container for 10 seconds was measured, and the concentration of the chemical liquid was measured. The measurement results are shown in Table 1. Further, the water temperature at the time of the test was 21 ° C to 23 ° C, and the weight of the residual drug in the drug cartridge was 21 g to 22 g.

Examples of the solid acid include fumaric acid, adipic acid, phthalic acid, succinic acid, maleic acid, methyl succinic acid, and boric acid. These solid acids are used alone or as a mixture of two or more.

Further, a surfactant may be contained. The surfactant is a mixture selected from the group consisting of ethylene oxide-propylene oxide copolymer, ethylene oxide-propylene oxide copolymer and sorbitan monooleate, and ethylene oxide-propane oxide copolymer and sulfonamide At least one of the group consisting of a mixture of sodium dioctyl acrylate.

Further, the coloring agent may also contain a coloring matter in the dissolved drug. The pigment may be a mixture of brilliant blue FCF alone or a mixture of blue No. 1 and other water-soluble pigments.

Further, the measurement results when the urinal was attached to the automatic washing urinal (US820C) manufactured by TOTO Co., Ltd. under the same conditions as described above are shown in Table 2.

However, the drug cartridge 1 has a different amount of water to be charged inside due to the type or shape of the urinal to be installed, or water pressure. Therefore, even if it is not easy to take water, it needs to be formed so that sufficient water can be taken inside. However, if it is installed in a place where it is easy to take water, it takes a lot of water, and the dissolution rate of the medicine C is accelerated, and the consumption of the medicine C is abrupt.

As described above, as shown in FIGS. 12 and 13, the medicine C is covered by the lid portion 9. The lid portion 9 is opened below, and the medicine C is covered from above to cover a part of the medicine C. If water is contained in the drug cartridge 1, the air in the lid portion 9 remains in the lid portion 9, so that water cannot enter the lid portion 9. As a result, the portion of the drug C covered by the lid portion 9 does not come into contact with water, and the dissolution rate of the drug C can be suppressed. Further, an adjustment portion 91 that can be appropriately cut at the site is provided on the side surface of the lid portion 9. When the adjustment portion 91 is cut to an appropriate depth, water enters the cut position in the lid portion 9, so that the contact area between the medicine C and water can be adjusted.

The adjustment portion 91 is preferably made thinner than the surrounding thickness for easy cutting. Further, as shown in FIG. 13 and FIG. 14, the number of the adjustment portions 91 having different heights of the cut-out portions is plural, and the dissolution rate of the medicine can be adjusted.

Further, as shown in Fig. 15, instead of the adjusting portion 91, the holes 92 having different heights which are pre-drilled can be sealed with a stopper or a plastic stopper 93, and the dissolution of the medicament can be adjusted by opening the hole 92 of a necessary height. speed.

However, the dissolution rate of the drug is affected by the amount of washing water that is also introduced from the introduction port 4. The smear of the smear-shaped urinal is faster than the urinal of the shower-shaped rinsing water, so that the dissolution of the medicinal agent is accelerated. Therefore, as shown in FIG. 16, in order to adjust the fluctuation of the dissolution rate of the medicine caused by the cleaning method of the urinal, a crack 41 is provided in the thin portion of the end portion of the introduction port 4, and the urinal such as the spreader is used for washing. When the urinal having a high water discharge speed is reduced, the amount of the washing water introduced from the introduction port 4 is reduced by canceling the outer portion 41a, whereby the dissolution rate of the medicine can be made slow.

Further, in the ninth embodiment, the lid portion 9 is separately provided. However, in the tenth embodiment shown in Fig. 14, the lid portion 9 and the lid portion 3 may be integrally formed.

<<Example 11: Long drain groove 8A>

Fig. 17 is a perspective view showing a modification of the drain groove of Fig. 10 in the eleventh embodiment.

In Fig. 17, 8A is an elongated drain groove (long drain groove) of the eleventh embodiment. The long drain groove 8A has a U-shaped cross section, and the entire width of the drug cartridge 1 is more than three times. The portion of the long portion that is in contact with the drug cartridge 1 in a plan view (Fig. 17(B)) is straight, and the portion that protrudes from the straight line to the left and right is slowly curved on the front side. Further, the front side of the long drain groove 8A (Fig. 17(C)) is formed in a slow mountain shape having an apex in the longitudinal direction. The length of the wall surface of the urinal used for the entire length of the elongate body is, for example, the length of the range in which the urinary stone or the like is to be removed, and the curvature of the curvature is consistent with the curvature of the wall surface of the urinal used. In Fig. 17, the long drain groove 8A is attached to the apex of the mountain shape at a height in the middle of the height of the drug cartridge 1.

"Slit K formed in the long drain groove 8A and the shape of the guide plate J"

Further, in the back side side wall A2 of the protruding portion of the protruding portion, a slit K of a lengthwise width is provided at a plurality of positions in the longitudinal direction (in FIG. 17 is 3), and a blocking plate J is provided to pass A portion of the chemical liquid Wf inside the long drain groove 8A faces the slit K so as to gradually extend from the downstream side end portion of the slit side K toward the upstream side end portion to the inner center of the long drain groove 8A. . Further, both end portions of the long drain groove 8A are bent toward the wall surface of the urinal by the end portion E (Fig. 17 (B)) of the front side wall A1.

"The Effect and Effect of Slit K and Blocking Plate J"

A part of the chemical liquid Wf passing through the inside of the long drain groove 8A can be made to be in the slit K direction by the stopper plate J, and is strongly ejected from the slit K toward the wall surface of the urinal. Further, the chemical solution Wf passing through the barrier plate J and the front side wall A1 is redirected to the direction of the slit K by the downstream one of the barrier plates J, is strongly ejected from the slit K, or passes through the barrier J and the front side Between the side walls A1. The liquid medicine Wf of all the stopper plates J is finally ejected from the slit K of the front end E of the long drain groove 8A toward the wall surface of the urinal.

Thus, the chemical liquid Wf passing through the inside of the long drain groove 8A is strongly ejected from any slit K toward the wall surface of the urinal, or is strongly ejected from the slit K formed at the front end of the long drain groove 8A toward the wall surface of the urinal .

Therefore, according to the embodiment 17, the chemical solution Wf of the overflow portion is strongly ejected from the plurality of slits K by the barrier plate J formed by expanding the entire length of the elongated body, so that the wall surface of the urinal is comprehensively involved. Can contact the drug solution Wf.

"Setting place of long drain groove 8A"
