Description

  The present invention relates to a toilet cleaning sheet that can be used for cleaning a toilet and can be cleaned in a water pool by a foaming action when discarded in a toilet as it is.

  In recent years, disposable fiber sheets are often used instead of rags for cleaning toilets. Among them, as shown in the following Patent Documents 1 to 4, a water-degradable fiber sheet impregnated with a cleaning liquid is preferred and used because it can be discarded as it is after use.

On the other hand, as cleaning agents for toilets, the following Patent Documents 5 to 7 disclose a tablet or loop tablet type (solid) cleaning agent containing a carbonate and an organic acid together with a cleaning agent such as a surfactant. ing. When such a cleaning agent is disposed in the toilet bowl, the carbonate and the organic acid react with each other using moisture as a medium, and carbon dioxide is generated, thereby improving the contact efficiency between the surfactant and the toilet wall surface, and soiling the hands. It is possible to clean the toilet pool and piping.

  When cleaning toilets using conventional water-decomposable fiber sheets, first wipe off the dirt other than the toilet puddles with the cleaning sheet made of the water-decomposable fiber sheets, and then discard the used sheets in the toilet puddles. After that, it is necessary to clean the toilet's puddle part with a brush or clean it with the above-mentioned toilet cleaner, so cleaning the parts other than the puddle and the puddle part is a double effort. It was necessary to do in.

  Therefore, a main problem of the present invention is to make it possible to easily clean a portion other than the water pool of the flush toilet and the water pool portion with a single labor, thereby greatly reducing the labor of cleaning.

  In order to solve the above-mentioned problem, as the present invention according to claim 1, in the water-degradable fiber sheet impregnated with the cleaning liquid, the microcapsules enclosing the carbonate and the microcapsules enclosing the organic acid are contained in the sheet. A toilet cleaning sheet is provided.

  In the present invention described in claim 1, the water-decomposable fiber sheet is made to contain microcapsules encapsulating carbonate and microcapsules encapsulating organic acid. Accordingly, when the portion other than the water reservoir of the toilet bowl is cleaned, the microcapsules enclosing the carbonate and the microcapsules enclosing the organic acid are ruptured, and a chemical reaction is started to generate carbon dioxide. And if the sheet is disposed in the toilet bowl as it is, the water pool part and the pipe part of the toilet bowl are cleaned by the foaming action, so that it is possible to easily clean the parts other than the water pool and the water pool part of the flush toilet in one time. The cleaning effort can be greatly saved.

  In the water-degradable fiber sheet impregnated with a cleaning liquid, the water-degradable fiber sheet is impregnated with one of a carbonate and an organic acid, and the other is enclosed in a microcapsule. A toilet cleaning sheet characterized in that it is contained in a conductive fiber sheet is provided.

  In the present invention according to claim 2, the water-degradable fiber sheet is impregnated with one of carbonate and organic acid in the water-decomposable fiber sheet, and the other is enclosed in a microcapsule and contained in the sheet. I made it. Therefore, when the part other than the water puddle of the toilet bowl is cleaned, the microcapsule ruptures, the enclosed carbonate (or organic acid) comes out, and the sheet is impregnated with the organic acid (or carbonate) impregnated in the sheet. The reaction starts and carbon dioxide gas is generated. And if the sheet is disposed in the toilet bowl as it is, the water pool part and the pipe part of the toilet bowl are cleaned by the foaming action, so that it is possible to easily clean the parts other than the water pool and the water pool part of the flush toilet in one time. The cleaning effort can be greatly saved.

  According to a third aspect of the present invention, there is provided a toilet cleaning sheet according to any one of the first and second aspects, wherein the microcapsule is a water-insoluble and pressure-sensitive microcapsule that bursts under pressure.

  The invention described in claim 3 uses a pressure-sensitive microcapsule that is water-insoluble and ruptures under pressure. By making the microcapsule used pressure-sensitive, when the toilet is cleaned with a sheet, the capsule is ruptured by pressure, and the encapsulated foaming agent component is released to the outside.

  As the present invention according to claim 4, there is provided a toilet cleaning sheet according to any one of claims 1 to 3, wherein the water-decomposable fiber sheet is impregnated with an antifouling agent.

  In the present invention described in claim 4, the anti-fouling agent is impregnated in the water-decomposable fiber sheet, and the wall surface of the water pool portion is coated with the anti-fouling agent every time the sheet is used. It makes it difficult to adhere.

  As described above in detail, according to the present invention, it is possible to easily clean the portion other than the water pool of the flush toilet and the water pool portion with a single operation, so that the labor for cleaning can be greatly saved.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[Example of structure of water-decomposable fiber sheet]
The sheet material of the toilet cleaning sheet 1 is paper or non-woven fabric made of fibers and a binder. Examples of fibers include cellulose fibers such as wood pulp, non-wood pulp, rayon and cotton, and biodegradable fibers made of polylactic acid. In addition, polyethylene fibers, polypropylene fibers, polyvinyl alcohol fibers, polyester fibers, polyacrylonitrile fibers, synthetic pulp, glass wool and the like can be used in combination with these fibers as a main component. Moreover, after cleaning the toilet, it is water disintegratable so that it can be disposed in the toilet as it is.

  For example, as shown in FIG. 1, the toilet cleaning sheet 1 is formed by laminating outer layer sheets 2 and 2 on both surfaces of an inner layer sheet 3 and integrating them by pressure bonding. It can be impregnated.

  The inner layer sheet 3 is a water-degradable fiber sheet mainly composed of wood pulp, and may be either beaten pulp or unbeaten pulp, but preferably unbeaten pulp. If the pulp used as a raw material is unbeaten, water disintegration is excellent. Moreover, although the kind of pulp used as a raw material is not particularly limited, it is preferable to use NBKP and LBKP so that the weight ratio thereof is 95: 5 to 50:50. Furthermore, it is desirable that the binder is not substantially contained. If the binder is 0.2% or less, water disintegration is not hindered.

  The outer layer sheets 2 and 2 may be either beating pulp or unbeaten pulp, but preferably beating pulp. The outer layer sheets 2 and 2 contain a water-soluble binder such as polyvinyl alcohol, carboxymethyl cellulose (CMC) or a salt thereof, starch or a derivative thereof, sodium alginate, or the like as a binder. Further, an appropriate crosslinking agent is used depending on the type of binder. For example, when polyvinyl alcohol is used as the binder, it is desirable to use boric acid as the crosslinking agent. Moreover, when using carboxymethylcellulose (CMC), it is desirable to use a polyvalent metal ion.

  Further, when beaten pulp is used to form the outer layer sheets 2 and 2, the strength and flexibility are excellent. The type of beaten pulp used as a raw material is not particularly limited, but it is preferable to use NBKP and LBKP so that the weight ratio thereof is 6: 4 to 10: 0. Since NBKP is superior in strength and flexibility compared to LBKP, when a large amount of NBKP is used, the strength and flexibility are improved. Further, since a binder such as polyvinyl alcohol is used for the outer layer sheets 2 and 2 together with the beating pulp, the beating pulp is easily broken at the time of disposal (at the time of water disintegration), and water disintegration is improved.

  The cleaning liquid impregnated in the inner layer sheet 3 and the outer layer sheets 2 and 2 preferably contains water as a medium and contains a surfactant, a water-soluble solvent, a disinfectant, and the like. In addition, auxiliary agents such as deodorants and preservatives can be appropriately contained.

  As the surfactant, for example, any of an anionic surfactant, a nonionic surfactant, a cationic surfactant and an amphoteric surfactant can be used.

  Examples of the water-soluble solvent include alcohols such as ethanol, methanol, propanol, butanol, glycerin, and sorbitol, and glycols such as ethylene glycol, diethylene glycol, polyethylene glycol, propylene glycol, dipropylene glycol, butylene glycol, and hexylene glycol. One or several types can be appropriately selected from the above or the like.

  The cleaning liquid may contain a disinfectant in addition to the above components. As the disinfectant, hydrogen peroxide, hypochlorous acid, sodium hypochlorite, quaternary ammonium salt, sodium benzoate and sodium paraoxybenzoate, polylysine, and the like are preferably used.

[Contains foaming components]
After cleaning the toilet with the toilet cleaning sheet 1, the toilet cleaning sheet 1 is dumped into the water reservoir in the toilet and is washed away by the water flow. The sheet 1 contains microcapsules 4 enclosing carbonates and microcapsules 5 encapsulating organic acids.

  Examples of the carbonate include sodium bicarbonate, sodium carbonate, potassium carbonate, and ammonium carbonate. Examples of the organic acid include tartaric acid, citric acid, succinic acid, malic acid sulfamic acid, and the like. be able to.

  On the other hand, as the microcapsule 4, it is desirable to use a pressure-sensitive microcapsule that is water-insoluble and bursts when subjected to pressure. As the capsule film-forming substance, an amino acid such as gelatin, a crosslinked acrylic resin, a formalin condensation polymer, or the like is used, and the capsule is produced by adjusting the pressure-sensitive value with a wall film modifier.

  The inclusion of the microcapsules 4, 4... In the toilet cleaning sheet 1 can be held between the sheets 2 and 3 in the case of the sheet 1 having a multilayer structure as shown in FIG. Further, as shown in FIG. 2, the fiber sheet 6 can be cut into the fiber at the time of manufacture, or can be applied to the upper surface of the fiber sheet 6 and fixed with a binder or the like as shown in FIG. 3. 2 and 3 can be adopted regardless of the sheet configuration.

  When cleaning the toilet, the microcapsules 4, 5... Are ruptured when the sheet 1 wipes dirt on the toilet surface, toilet seat, floor around the toilet, etc. Are released to the outside, the carbonate and organic acid undergo a chemical reaction to release carbon dioxide. When the sheet 1 is discarded in the toilet puddle after the wiping and cleaning is completed, the wall surface and the pipe portion of the puddle portion of the toilet bowl are washed by the foaming action due to the release of carbon dioxide gas. Then, the sheet 1 is made to flow when the foaming action is stopped.

  The sheet 1 is preferably impregnated with an antifouling agent together with the cleaning liquid described above. As the antifouling agent, known ones such as a copolymerizable monomer such as an amphoteric polymer compound, a cationic polymer compound, and a nonionic polymer can be used. When impregnated with the antifouling agent, the antifouling agent adheres and accumulates on the wall surface of the water pool portion every time it is used, and a coating layer is formed.

  By the way, in the said form example, although both the microcapsule which enclosed carbonate and the microcapsule which enclosed organic acid were contained in the sheet | seat, one of carbonate and organic acid was made into the said hydrolysable fiber sheet. It is also possible to impregnate and enclose the other in a microcapsule so as to be contained in a sheet. In this case, when the part other than the puddle of the toilet bowl is cleaned, the microcapsule is ruptured, the enclosed carbonate (or organic acid) comes out, and the organic acid (or carbonic acid impregnated in the sheet) is impregnated. Salt) and start to react with carbon dioxide. Furthermore, a microcapsule enclosing a carbonate (organic acid) may be a two-liquid phase microcapsule surrounded by a microcapsule enclosing an organic acid (carbonate).

[Other examples]
(1) In the above embodiment, a water-insoluble, pressure-sensitive macrocapsule was used as the microcapsule, and it was ruptured by the pressure at the time of wiping, but it was inactive with the surrounding washing liquid and was discarded in the toilet bowl. It is also possible to use microcapsules that dissolve upon contact with water. Examples of such microcapsules include those described in JP-A-63-137996. In the microcapsule, at least one selected from a water-soluble polymer and a water-absorbing polymer, the wall membrane is made of cellulose acetate petrate, cellulose acetate propionate, polystyrene, polyamide or polyester, and an active ingredient as a core substance. It is a microcapsule containing seeds, and this microcapsule does not swell or deteriorate in an alkaline aqueous solution containing a surfactant and the like, and when diluted in water, water permeates inside the capsule. The wall film is ruptured by the water-soluble polymer or water-absorbing polymer swollen by the water.

It is a cross-sectional view showing a structural example of a water-decomposable fiber sheet and a holding mode of microcapsules. It is a transverse cross section at the time of making a microcapsule into a fiber of a water-decomposable fiber sheet, and holding it.
