Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet bowl cleaner and a toilet bowl cleaning method. More specifically, the present invention relates to a toilet bowl cleaner installed on a wall of a toilet bowl or a dissolver installed in the middle of a flush water pipe. Or, install it in the toilet bowl or trap, and dissolve the washing water little by little in the wash water to wash the toilet surface, the trap part of the toilet and the drain pipe part, and clean the toilet surface with traps and drain pipes. TECHNICAL FIELD The present invention relates to a chemical for preventing stains on the part and adhesion of scales, slimes, and the like, and a method for cleaning a toilet bowl using the chemical.

[0002]

2. Description of the Related Art A mixed molded product composed of a surfactant, a fragrance, a pigment, etc. is installed in a tank for washing water of a toilet bowl, an upper hand-washing section or a container suspended on the surface of a toilet bowl, and the medicine is washed in the washing water. A large number of detergents for toilet bowls have been proposed and put into practical use, which are dissolved little by little to prevent stains on the toilet bowl surface and to give a refreshing feeling by coloring the wash water.

In addition, we set solid acid as an active ingredient in the trap part of the urinal for boys to dissolve it little by little in the wash water, and prevent the scale and so-called urine stone from adhering to the trap part and the drain pipe. To propose a drug (Japanese Patent Laid-Open No. 62-038
299), part of which is put to practical use.

Furthermore, a similar chemical is stored in a dissolver installed in the middle of the toilet flush water drainage pipe, part of the wash water is taken into the dissolver, and the flush water in which the chemical is dissolved is returned to the pipe. Also, a method for simultaneously preventing dirt on the toilet surface and adhesion of urine stones to the trap portion and the drainage pipe by flowing down the toilet surface has been proposed (JP-A-3-200887, JP-A-3-223386, JP-A-3-22386). 224923), part of which has been put to practical use.

[0005]

The method of storing a drug having a solid acid as an active ingredient in a dissolver installed in the toilet flush water pipe and dissolving it in the flush water is as follows: It has the excellent feature that it can prevent the adherence of urinary stones to the pipes at the same time, but in some toilets black deposits are generated inside the dissolver, the flush water outflow hole part and trap part of the toilet bowl, and the dissolver This was a problem because the operation of the toilet and the wash water outflow from the toilet were blocked.

Further, a drainage pipe is installed in the center of a trap, which is usually called a trap removable urinal, and a water sealing part is formed by the pipe and a projection part of a perforated plate installed from above so as to surround the pipe. With a urinal with a special trap structure, the urine in the trap was not sufficiently replaced with flushing water, and a high concentration of urine was likely to remain in the trap compared with a normal toilet bowl, and the flow rate of flushing water in the trap was slow. Since solids are not discharged from the trap, soft adherents called microbial-derived slime are generated, and it is difficult to prevent the slime from being generated by a drug containing a solid acid as an active ingredient.

[0007]

Means for Solving the Problems The inventors of the present invention have conducted extensive studies to solve the above-mentioned problems, and as a result, did they use a toilet bowl cleaner composition containing a slime inhibitor in the toilet cleaner? , Throw a chemical containing a slime inhibitor as a separate agent from the toilet cleaner into the dissolver installed in the middle of the piping, or put a chemical containing a slime inhibitor as a separate agent from the toilet cleaner in the toilet It is possible to effectively prevent black deposits generated in the dissolver, the flush water outflow hole portion of the toilet bowl and the trap portion, and slime generated in the trap of the trap removable urinal by putting it in the trap or trap. Found and completed the present invention.

In the present invention, the slime preventive agent means a substance having an action of inhibiting the growth of mold and bacteria.

As an anti-slime agent for preventing the generation of black deposits at the mouth of flushing water of a dissolver or a toilet bowl, a compound which is effective in inhibiting the growth of mold and is generally known as a fungicide or bactericide. Can be used. For example, methylenebisthiocyanate, 2-methoxycarbonylaminobenzimidazole, 2,3,3-triiodoallyl alcohol, 2-pyridinethiol-1-oxide zinc salt, 4
-Chlorophenyl-3-iodopropargyl formal,
3-iodo-2-propargyl butylcarbamic acid, 3-
Bromo-2,3-iodo-2-propenylethyl carbonate, 5-chloro-2methyl-isothiazoline-3-
On, 2,2-dithio-bis- (pyridine-1-oxide), diiodomethyl-p-trisulfone, 2,3
5,6-tetrachloro-4- (methylsulfonyl) pyridine, 2-thiocyanomethylthiobenzthiazole, thiabendazole, 1-bromo-3-chloro-5,5-dimethylhydantoin, trichloroisocyanuric acid and the like can be mentioned. .

In particular, methylenebisthiocyanate, 2-
Methoxycarbonylaminobenzimidazole, 2,
3,3-triiodoallyl alcohol, 2-pyridinethiol-1-oxide zinc salt, 4-chlorophenyl-
3-iodopropargyl formal, 3-iodo-2-propargyl butylcarbamic acid, 3-bromo-2,3-diiodo-2-propenylethyl carbonate, diiodomethyl-p-trisulfone, 2,3,5,6 -Tetrachloro-4- (methylsulfonyl) pyridine, thiabendazole and the like have a strong growth inhibitory effect on slime,
Moreover, since the solubility in water is as low as 0.1 to 150 ppm, the slime inhibitor added to the detergent is not extracted with water, and the wash water immediately after the detergent is put into the dissolver and after a lapse of time has passed. The concentration of the slime-preventing agent that elutes in the solution becomes relatively constant, and even if the amount of the slime-preventing agent added to the toilet cleaner is small, about 0.1 to 2%, it is possible to effectively prevent the generation of slime, and therefore it is preferably used To be done.

Further, 5-chloro-2methyl-isothiazolin-3-one and 2,2-dithio-bis- (pyridin-1-oxide) are easily dissolved in water (the former is 8. Commercially available as a 6% aqueous solution, the latter has a saturated aqueous solution concentration of 1.13%). It has the characteristic that the wall surface is not contaminated by the deposition of slime inhibitor.

In order to prevent slime generated in the trap of the detachable urinal, the compound which is effective in inhibiting the growth of bacteria and is generally known as an antibacterial agent or bactericidal agent, for example, methylenebisthiocyanate , 2,
3,3-triiodoallyl alcohol, 3-iodo-2
-Propargyl butylcarbamic acid, 3-bromo-2,3
-Iodo-2-propenylethyl carbonate, 5-chloro-2methyl-isothiazolin-3-one, 2-thiocyanomethylthiobenzthiazole, 2,2-dibromophophophonitroethanol, 2,4,4-trichloro-
2-hydroxy-diphenyl ether, 2-bromo-2
-Nitro-1,3-propanediol, didecyldimethylammonium chloride, tetradecyldimethylbenzylammonium chloride, cetylpyridinium chloride, 1-bromo-3-chloro-5,5-dimethylhydantoin, trichloroisocyanuric acid, etc. used.

In particular, methylenebisthiocyanate, 2,
3,3-triiodoallyl alcohol, 1-bromo-3-chloro-5,5-dimethylhydantoin, and the like have a strong growth inhibitory effect on bacterial-derived slime generated in traps of trap removable urinals, and water. Since its solubility in water is as low as 10 to 5000 ppm, it is special when a molded product of these slime inhibitors alone or in a mixture with other appropriate components is installed in a dissolver, a toilet bowl part, a trap, etc. It has a feature that it can be dissolved at an appropriate dissolution rate without the addition of a special dissolution regulator, and a slime inhibitor can be added to trap wastewater at a stable concentration over a long period of time to prevent the generation of slime.

Further, 5-chloro-2methyl-isothiazolin-3-one has a large solubility in water and a strong skin irritation, so that although it has an excellent slime-preventing effect, it is difficult to use, but it is difficult to use a polymolecular compound. By using the inclusion compound as a host, it can be used as a good antislime agent. Examples of the host compound include tetrakis (4-hydroxyphenyl) ethane and 1,1,6,6-tetraphenyl-2,4-hexadiyne-1,6-diol.

The anti-slime agent is added to the detergent as one kind alone or as a mixture of two or more kinds. When the anti-slime agent is added as a mixture of two or more kinds, the anti-slime agents mixed are different antibacterial agents. A drug that has characteristics and does not cause alteration or the like by mixing is selected.

The slime inhibitor can be added to the detergent by various known methods, but it is preferable that the slime inhibitor is uniformly dispersed in the detergent. For example, when the cleaning agent is manufactured by a manufacturing method in which a heated and melted chemical is filled in a mold such as plastic and cooled and solidified, a method of adding a slime inhibitor to the melt and uniformly mixing is exemplified, and a mixture of powders. When it is produced by a tableting molding method, a method of adding it to the powder and uniformly mixing it can be exemplified.

The toilet bowl cleaning agent of the present invention is mainly used by being stored in a dissolver installed in the middle of the flush water pipe of the toilet bowl. Store in a dissolver installed at the outlet of the wash water in the tank or above the wash water tank, or a dissolver installed in the trap part of the toilet bowl, or use the molded body as it is in each of the above parts. You can also

The toilet bowl cleaner of the present invention contains a solid acid for preventing urinary stones and an anti-slime agent in the same molded body, and simultaneously dissolves both components at the time of use, as well as a molded body containing a solid acid. Body and molded body containing anti-slime agent are separately molded, both molded bodies are put into the dissolver at the same time and used, only the molded body containing only the mildew-proofing agent and solid acid in the dissolver And a molded article containing an antibacterial agent is put into the trap of the trap-removable urinal.

When a solid acid having a slow solubility or an anti-slime agent is used as an active ingredient, the drug does not take the form of a molded product but is put directly into the dissolver or trap in the form of granules or powder. It can also be used as it is, or a liquid or a readily soluble drug can be filled in a container having a filter or the like at its mouth and placed in a dissolver for use.

When a solid acid having a slow solubility or a slime inhibitor is used as an active ingredient, a method of forming a molded body containing a disintegrant and disintegrating it in a trap or a dissolver to obtain a powder state is also preferably used. It As the disintegrator, calcium salt of carboxymethyl cellulose, boron oxide and the like are preferably used.

[0033]

[Function] A detergent containing a solid acid as an active ingredient is stored in a dissolver installed in the toilet flush water pipe, and when the detergent is dissolved in the wash water, in the dissolver or in the flush water outflow hole portion and trap portion of the toilet bowl. The generated black deposits are the result of research by the present inventors,
It was found that the mold in the air grew with the surfactant in the detergent and the organic components in tap water as nutrient sources, and the slime generated in the trap of the detachable trap urinal is derived from bacteria. It was

The slime inhibitor added to the toilet cleaner dissolves other components of the detergent in the wash water and also dissolves in the wash water, and is dissolved in the dissolver, the wash water outflow hole portion and the trap portion of the toilet bowl. Prevents mold and bacteria from growing and forming deposits (slime).

When the chemical containing the slime preventive agent is directly put into the trap of the urinal which is detachable from the trap, the concentration of the slime preventive agent in the trap is reduced during a long time when the use of the toilet bowl is stopped for a long time such as at night or on holidays. Since it is significantly higher than in normal times, it becomes possible to kill the bacteria that have propagated, and the effect is particularly remarkable.

In addition, the inside of the trap of the trap-removable urinal has a large area inside the trap, and the inside of the trap is divided into several parts, so that it takes a long time to disperse the drug. Even if the drug is present only in the part, a phenomenon occurs in which the drug concentration does not reach the concentration that can sufficiently suppress the growth of bacteria in the part far from the drug inside the trap.

As a solution to this problem, a slime inhibitor having a low solubility is added in the form of granules or powder, or a tablet containing a disintegrant is disintegrated in a trap. Even if the amount of drug is small, slime can be effectively prevented.

The urinary stones that adhere to the traps and drainage pipes of the toilet bowl are because the urine in the urine is decomposed into ammonia and carbon dioxide by the action of microorganisms and the pH rises, so that the urine, which is originally weakly acidic, becomes alkaline. The water-soluble calcium component in the urine is bound to carbon dioxide and phosphoric acid to precipitate as a water-insoluble calcium compound and adhere as a scale. An acidic substance suppresses the rise in urine pH by its pH adjusting action and prevents the generation of urinary stones, but since it also suppresses the activity of microorganisms by adding a slime preventive agent, the toilet cleaning agent containing a slime preventive agent The urinary stone prevention effect is higher than the urine stone prevention effect as compared with a toilet bowl cleaner containing only acidic substances.
