Background Art

Sink filters and drain pipes, where food residue is left behind during cooking and disposal, are constantly submerged in water, creating an environment conducive to microbial growth. This can lead to soiling and the development of odors. Cleaning these filters and drain pipes to ensure they remain clean is inconvenient, time-consuming, and labor-intensive. However, there are no specific solutions other than replacing the filter or drain pipe, creating a significant problem.

To address this issue, U.S. Patent Application No. 14-529388 discloses a two-liquid system for cleaning pipes using hydrolytic enzymes such as amylase to foam hydrogen peroxide. However, this system suffers from the drawback of being unable to fully exert its bactericidal and bleaching effects, as hydrogen peroxide has significantly lower bactericidal and bleaching capabilities than sodium hypochlorite.

In addition, U.S. Patent Publication No. US2003/0171234A1 discloses a method for cleaning pipes by simultaneously pouring a viscous sodium hypochlorite composition and a foaming agent and allowing them to foam. However, this cleaning method is not easy to evenly mix the sodium hypochlorite and foaming agent. Furthermore, in vertically arranged water tank pipes, the foam cannot be retained for a long time and discharged immediately, thus limiting the cleaning capacity. Furthermore, mixing the sodium hypochlorite composition with acidic hydrogen peroxide to achieve the foaming effect produces a large amount of chlorine gas that is harmful to the human body.

Therefore, there is a current need for a tool or method that can more effectively clean sink drains by extending the duration of the cleaning effect of a foaming cleaning composition. Furthermore, in order to enhance cleaning performance, it is crucial to adjust the component ratios in a foaming cleaning composition to fully induce the foaming reaction and suppress the generation of chlorine gas.

Summary of the Invention

Problems to be solved by the invention

In view of the above situation, the present invention aims to provide a cleaning container that utilizes foam generated by a foaming drainpipe cleaner to clean a filter, allowing the cleaner to slowly flow into the drainpipe to continuously clean the drainpipe.

Another object of the present invention is to provide a drain cleaning composition that maximizes the cleaning effect on drains and suppresses the generation of chlorine gas.

Another object of the present invention is to provide a set including a drain cleaning agent for foaming cleaning and a drain cleaning container for foaming cleaning.

In addition, the problem to be solved by the present invention is to provide a method for simultaneously and effectively cleaning a kitchen sink filter and a drain pipe by using the cleaning container.

Solutions to Problems

To solve the above problems, the present invention provides a cleaning container capable of slowly flowing a foaming drain cleaner into a drain pipe, and a method for efficiently foaming and cleaning a kitchen sink filter and drain pipe using the container.

To overcome the aforementioned problems of the prior art, the inventors of the present invention, through dedicated research and effort, developed a cleaning container comprising an inlet and an outlet that allow a foaming cleaning agent to slowly flow into the filter, drain, and drain pipe. The inventors surprisingly discovered that when the foaming cleaning agent and the cleaning container are used together, the richly foamed cleaning agent is discharged through the inlet, effectively cleaning the filter and drain. Furthermore, the slow discharge of the foaming cleaning agent through the outlet allows the drain pipe to be foamed for a prolonged period of time, significantly improving the cleaning effectiveness of the kitchen sink filter, drain, and drain pipe. This led to the completion of the present invention.

The present invention provides a drain cleaning container for foaming cleaning, which includes: a container body having a storage space formed therein; an inlet for allowing a drain cleaning agent for foaming cleaning to flow into the storage space; and at least one discharge port formed in the container body so that the storage space contained in the container body is connected to a drain pipe and the cleaning agent contained in the storage space is discharged to the drain pipe, and the discharge port can discharge the cleaning agent at a slower speed than when the cleaning agent is immediately disposed of to the drain pipe. The case of immediately disposing the cleaning agent to the drain pipe refers to the case of not using the cleaning container and directly disposing the cleaning agent to a drain outlet or drain pipe. The cleaning container can be provided at a drain outlet for connection to a drain pipe.

The foaming drainpipe cleaning container allows the foam generated by the foaming cleaning agent composition to overflow through the inlet and remain in the drain outlet and filter, effectively cleaning the drain outlet or filter. Furthermore, the cleaning agent is slowly discharged through the narrow outlet, continuously maintaining the cleaning effect on the drainpipe, thereby achieving an excellent drainpipe cleaning effect. Preferably, the foaming drainpipe cleaning container uses the generated foam to clean the drain outlet or filter while simultaneously using the cleaning agent flowing out of the narrow outlet to clean the drainpipe.

As one embodiment, the foaming cleaning container for drain pipes can be in the form of a cup with a drain outlet, in order to utilize the foam generated by the foaming cleaning agent to clean the drain outlet and filter, and to allow the cleaning agent to flow slowly into the drain pipe. FIG1 shows an embodiment of the cup-shaped foaming cleaning container for drain pipes.

As one embodiment, the drainpipe cleaning container for foaming cleaning can use a container with a shape in which the diameter gradually decreases from top to bottom. FIG5 shows a diagram of a drainpipe cleaning container for foaming cleaning having the characteristics described above. The diameter of the upper surface can be the same as or slightly smaller than the diameter of the drain outlet or the filter. In addition, the diameter of the upper surface can be a preset diameter so that it can be inserted into the drain outlet or the filter to form a socket combination. In addition, the upper surface can also include a card table so that it can be clamped on the drain outlet along the edge of the upper end. In summary, since the shape of the container is a shape in which the diameter gradually decreases from top to bottom, the upper end of the container can be hung on the drain outlet or the filter, and the lower end can enter the inner side of the filter.

Furthermore, the foaming cleaning drainpipe cleaning container may include a concave-convex structure with concave-convex grooves arranged at predetermined intervals, so that the cleaning agent discharged through the inlet flows along the outer surface. With such a concave-convex structure, even if the container is in close contact with a filter or drain outlet, the discharged cleaning agent will flow downward along the concave-convex structure, thereby improving the cleaning effect of the filter or drain outlet.

In the foaming drain cleaning container, the cleaning agent contained in the holding space can be discharged at a slower rate than when the cleaning agent is immediately discharged into the drain. The rate is not particularly limited, but the rate can be such that the cleaning agent contained in the holding space is discharged over a period of 10 to 180 minutes, preferably 20 to 150 minutes, and more preferably 30 to 120 minutes. By adjusting the discharge rate so that the cleaning agent is discharged slowly over a longer period of time, a continuous cleaning effect can be achieved on the drain, thereby significantly improving the cleaning effect compared to a method of simply pouring the cleaning agent into the drain outlet.

In the present invention, the discharge port of the cleaning container may have a preset diameter so that the cleaning agent can be discharged through the discharge port at a speed of 1 to 100 ml/min, preferably 5 to 50 ml/min, and more preferably 7 to 20 ml/min.

In the drainpipe cleaning container, the preset diameter of the discharge port can be 0.1 to 10 mm, preferably 0.3 to 5 mm, and more preferably 0.5 to 3 mm. When the diameter of the discharge port is less than 0.1 mm, the cleaning agent flows out too slowly, resulting in a prolonged cleaning time. When the diameter of the discharge port exceeds 10 mm, the cleaning agent flows out too quickly, resulting in a weak effect of improving the cleaning ability expected by the present invention.

Furthermore, according to a preferred embodiment of the present invention, the cleaning container may include discharge ports having a predetermined diameter and number, so that the cleaning agent can be discharged through the discharge ports for 10 to 180 minutes, preferably 20 to 150 minutes, and more preferably 30 to 120 minutes. In particular, when the discharge time of the foaming cleaning agent is less than 30 minutes, the average killing rate of microorganisms is low, while when it exceeds 120 minutes, the enhanced sterilization effect is minimal. Therefore, the discharge time is preferably controlled between 30 and 120 minutes.

In the drain cleaning container, the preset diameter of the discharge port can be 0.1 to 10 mm, preferably 0.3 to 5 mm, more preferably 0.5 to 3 mm, and most preferably 1 to 2.5 mm. In addition, the number of the discharge ports can be 1 to 8, preferably 1 to 6, and more preferably 2 to 5. Preferably, when the drain cleaning container of the present invention has 2 to 5 discharge ports with a diameter of 1 to 2.5 mm, the cleaning agent can be discharged through the discharge ports for 30 to 120 minutes, so that the drain cleaning effect can be best achieved. More preferably, the cleaning agent of the present invention can be used to clean the drain for more than 50 minutes to fully exert its cleaning effect. Even if the cleaning is continued, there will be no significant difference in the effect, and it will only unnecessarily extend the use time.

In addition, the present invention provides a drain pipe cleaning container for foaming cleaning, which includes: a container body having a storage space formed inside; an inlet for allowing a drain pipe cleaning agent for foaming cleaning to flow into the storage space; at least one discharge outlet formed in the container body so that the storage space contained in the container body is connected to a drain pipe and the cleaning agent contained in the storage space is discharged into the drain pipe; and a mesh component through which the drain pipe cleaning agent for foaming cleaning passes, so that the cleaning agent can be discharged at a slower speed compared to the case where the cleaning agent is immediately disposed of into the drain pipe.

In the drainpipe cleaning container for foaming cleaning, a mesh member for allowing the drainpipe cleaning agent to pass through can be formed at the inlet. This allows the first and second doses of cleaning agent, flowing through the mesh member at the inlet, to diffuse downward and mix evenly within the cleaning container. Furthermore, the foam of the foaming cleaning agent is discharged to the outside through the mesh member formed at the inlet, thereby forming a denser foam, significantly improving the cleaning effect.

In the present invention, the mesh member may be in the form of a net, or a member made of a non-woven fabric with uneven spacing may be used instead of the mesh member with a predetermined spacing, but the present invention is not limited thereto.

Preferably, the pore size of the mesh member is 100 to 10,000 μm, more preferably 300 to 4,000 μm, more preferably 400 to 2,000 μm, and most preferably 400 to 900 μm. A pore size of less than 100 μm is unsuitable because the cleaning composition does not readily pass through it. A pore size exceeding 10,000 μm reduces the homogenization of the cleaning mixture and the densification of the discharged foam.

In the present invention, the mesh member can be composed of metal wire, and the metal wire includes any one or more materials selected from the group consisting of stainless steel, glass fiber, and polyethylene (PE). In addition, the mesh member can be a member in which the longitudinal and transverse lines of the metal wires intersect perpendicularly to form a square mesh. From the perspective of the present invention, when the cleaning agent composition flows through the mesh member as described above, the homogenization effect of the cleaning agent flowing in and the densification effect of the foam discharged through the inlet are most excellent.

As one embodiment, in order to utilize the foam generated by the foaming cleaning agent to clean the drain outlet and the filter and allow the cleaning agent to slowly flow into the drain pipe, the drain pipe cleaning container for foaming cleaning includes a drain outlet and can be in the form of a cup with a mesh component formed at the inlet. Figure 12 shows an embodiment of the cup-shaped drain pipe cleaning container for foaming cleaning.

In the present invention, as the material of the above-mentioned drain pipe cleaning container for foaming cleaning, commonly used plastic materials such as HDPE (high-density polyethylene), LDPE (low-density polyethylene), PET (polyethylene terephthalate), PP (polypropylene), PE (polyethylene), PC (polycarbonate), PS (polystyrene) or ABS (acrylonitrile butadiene styrene), paper, glass or metal can be used.

In the present invention, the drain cleaning composition for foaming cleaning may be any commonly used cleaning composition such as a composition containing a bleaching agent for cleaning filters, drain outlets, or drain pipes, without particular limitation.

Preferably, the present invention provides a foaming drainpipe cleaning agent comprising a first composition and a second composition, respectively, wherein the first composition comprises a chlorine-based cleaning agent, preferably hypochlorite, and the second composition comprises a foaming agent, preferably hydrogen peroxide. More specifically, the foaming drainpipe cleaning agent may comprise a first composition comprising a chlorine-based cleaning agent and a second composition comprising a foaming agent. The first or second composition may comprise an anionic surfactant, a nonionic surfactant, or a mixture thereof.

In the present invention, the first and second compositions can be mixed in the container of the foaming drainpipe cleaning container of the present invention before use. Furthermore, the weight ratio of the first and second compositions (first composition:second composition) can be 10:1 to 1:10, preferably 5:1 to 1:5, and more preferably 3:1 to 1:3. Within this weight ratio range, foaming and cleaning performance are optimal.

In the present invention, the reaction of hypochlorite and hydrogen peroxide as the chlorine-based cleaning agent component and foaming agent is preferred. A foaming reaction that generates oxygen gas, as shown in the following reaction formula 1, can be used. In addition, various other methods can be used to generate the foaming reaction, such as the reaction of sodium carbonate or sodium bicarbonate with an organic acid (such as citric acid or lactic acid) or an inorganic acid (such as aminosulfonic acid). Similar effects can also be achieved by adding surfactants or disinfectants. However, in the present invention, a foaming cleaning effect can be generated by reacting hypochlorite and hydrogen peroxide as the main components. In this case, the cleaning effect is superior to other foaming cleaning methods.

Reaction 1:

NaOCl+H ₂ O ₂ NaCl+H ₂ O+1/2O ₂

In the present invention, the first agent may contain a chlorine-based cleaning agent component as a main component, preferably hypochlorite, which has excellent sterilization and bleaching effects, decomposes quickly after dilution, has little residual content, and has low oral toxicity. Therefore, it can be effectively used for sterilization and disinfection of food and tableware.

The hypochlorite used as an effective component for sterilization or disinfection can be one or more selected from the group consisting of sodium hypochlorite (NaOCl), potassium hypochlorite, calcium hypochlorite, and magnesium hypochlorite. Sodium hypochlorite can be preferably used as the hypochlorite.

The chlorine-based cleaning agent component, preferably hypochlorite, can be used in an amount of 0.1 to 30% by weight, preferably 5 to 27% by weight, and more preferably 15 to 25% by weight, relative to the total weight of the first composition. When the amount of the chlorine-based cleaning agent component used is less than 0.1% by weight, its bactericidal or disinfecting function is weak, while when it exceeds 30% by weight, its compatibility with surfactants is poor and the stability of the chlorate ion itself is also adversely affected.

In the present invention, to enhance the foaming and cleaning effect of the cleaning composition, the hypochlorite and hydrogen peroxide may be contained in an equivalent ratio (hypochlorite:hydrogen peroxide) of 1:1 to 10:1, preferably 1.25:1 to 9:1, more preferably 2:1 to 7:1, and most preferably 3:1 to 5:1. Cleaning compositions with this equivalent ratio exhibit the best foaming and cleaning performance.

The present invention also provides a drain cleaning composition comprising a first component containing a chlorine-based cleaning agent, a second component containing a foaming agent, and a pH adjuster. Preferably, the composition provides a two-component foaming cleaning agent for drain cleaning. Preferably, the chlorine-based cleaning agent may be a hypochlorite, for example, and the foaming agent may be a hydrogen peroxide, for example. The addition of a pH adjuster to maintain a pH of 9 or above when the chlorine-based cleaning agent and foaming agent are mixed significantly suppresses the generation of chlorine gas, which is harmful to the human body.

More specifically, because the drain cleaning composition of the present invention includes a pH adjuster, it can maintain the pH of the composition comprising the first-part chlorine-based cleaning agent component, preferably sodium hypochlorite, at a level of 12 or higher. Furthermore, after mixing the second-part acidic foaming agent composition of the present invention with the first-part composition, the pH of the mixture can still be maintained at a level of 9 or higher, preventing the generation of significant amounts of chlorine gas. Therefore, kitchen sink filters and drains can be safely foamed and cleaned.

In the present invention, the process of mixing a first agent, primarily sodium hypochlorite, and a second agent, primarily acidic hydrogen peroxide, produces a large amount of harmful chlorine gas. Because chlorine gas is extremely dangerous to the human body, the formulations of the first and second agents are carefully designed to minimize chlorine gas production. In particular, it is preferred that the first and second agents be mixed in a manner that minimizes chlorine gas production. Sodium hypochlorite produces large amounts of chlorine gas at a pH below 9, making it extremely dangerous to the human body. Furthermore, mixing the first and second agents can also produce a rapid and instantaneous burst of chlorine gas. Therefore, to prevent this, it is crucial to adjust the pH of the mixture.

In the present invention, during the mixing of the first and second agents, a portion of the sodium hypochlorite contained in the first agent reacts with hydrogen peroxide to convert into sodium chloride, water, and oxygen. To prevent the rapid decomposition of the remaining sodium hypochlorite after the reaction and the generation of a large amount of chlorine gas, the pH of the mixture of the first and second agents is preferably 9 to 14, more preferably 11 to 14, which is safer.

The drain cleaning composition of the present invention includes a pH regulator, thereby significantly suppressing the generation of chlorine gas when the first and second agents are mixed. The amount of chlorine gas generated when using the drain cleaning composition is less than 300 ppm, preferably less than 100 ppm, and more preferably less than 50 ppm. For reference, according to the Material Safety Data Sheet (MSDS) provided by the safety and health agency, the toxicity concentration (LC50) of chlorine gas is 293 ppm. When using the drain cleaning composition of the present invention, the amount of chlorine gas generated can be significantly suppressed compared to the toxicity concentration (LC50), thereby being extremely safe for the human body.

In the present invention, a pH adjuster may be used in the drain cleaning composition to maintain a pH of 9 or higher after mixing the first and second components, thereby minimizing the generation of chlorine gas. The pH adjuster may be any one or more selected from the group consisting of sodium hydroxide (NaOH), potassium hydroxide (KOH), sodium _silicate ( _{Na3SiO3 , Na4SiO4} ), and _{sodium carbonate (Na2CO3 )} , with sodium hydroxide being preferred.

The drain cleaning composition of the present invention contains a pH adjuster, so when the first and second agents are mixed, the pH value can be maintained at 9 to 14. Preferably, the pH adjuster can be included in the first agent, in which case the pH of the first agent can be maintained at 12 to 14.

In the present invention, the equivalent ratio of the pH adjuster to the total amount of hydrogen ions of the acidic substance contained in the second agent (pH adjuster: equivalent amount of the total amount of hydrogen ions of the acidic substance contained in the second agent) is 1.1 to 10:1, preferably 1.1 to 5:1, and more preferably 1.1 to 3:1. When the content of the pH adjuster is less than an equivalent ratio of 1.1:1 (pH adjuster: equivalent amount of the total amount of hydrogen ions of the acidic substance contained in the second agent), the amount of chlorine gas generated will increase sharply because the pH value after mixing is less than 9. When the content of the pH adjuster exceeds an equivalent ratio of 10:1 (pH adjuster: equivalent amount of the total amount of hydrogen ions of the acidic substance contained in the second agent), the reactivity of the chlorine-based cleaning agent component and the foaming agent will decrease.

In the present invention, the first composition may include an anionic surfactant, a nonionic surfactant, or a mixture of the two to enhance the bactericidal and disinfecting ability of hypochlorite ions and improve their cleaning effect and viscosity. Preferably, the anionic surfactant may include an alkyl ether sulfate of the following chemical formula 1, preferably SLES (sodium lauryl ether sulfate).

Chemical formula 1:

R(CH ₂ CH ₂ O) _n SO ₃ M

(In Chemical Formula 1, R represents a C10-C16 alkyl group, n represents an integer of 1-5, and M represents sodium or potassium.)

Preferably, the anionic surfactant may include a mixture of the alkyl ether sulfate of the above Chemical Formula 1 and the alkylamine oxide of the following Chemical Formula 2. Preferably, as the alkylamine oxide of the following Chemical Formula 2, lauramine oxide may be used.

Chemical formula 2:

(In Chemical Formula 2, R' represents a C10-C16 alkyl group.)

In the present invention, by using the mixture of the above-mentioned alkyl ether sulfate and alkylamine oxide as the anionic surfactant, due to the synergistic effect between the surfactants and the interaction between the surfactant and hypochlorite, it is possible to form excellent cleaning ability and viscosity compared with the case of using each component alone.

Preferably, the weight ratio of the alkyl ether sulfate to the alkylamine oxide can be 1:20 to 20:1, preferably 1:10 to 10:1, more preferably 1:1 to 10:1, and most preferably 3:1 to 7:1 (alkyl ether sulfate:alkyl amine oxide). When the weight ratio of the alkyl ether sulfate to the alkylamine oxide is within this range, the viscosity of the first composition of the present invention can be optimized.

In the present invention, the first composition may further include an inorganic alkali salt to promote viscosity formation due to the interaction between the surfactant and hypochlorite ions while maintaining alkalinity. The inorganic alkali salt may be any one or more selected from the group consisting of sodium carbonate ( _Na2CO3 ), sodium bicarbonate ( _NaHCO3 ), sodium _silicate ( _Na3SiO3 , _Na4SiO4 ) _, and sodium hydroxide (NaOH), with _sodium hydroxide being preferred.

The inorganic alkali salt is used in an amount of 0.1 to 10% by weight, preferably 0.5 to 7% by weight, relative to the total weight of the first composition. When the inorganic alkali salt is used in an amount less than 0.1% by weight, the effects of maintaining alkalinity and promoting viscosity formation are minimal, while when the amount exceeds 10% by weight, the reactivity of hypochlorite with hydrogen peroxide decreases.

The type and amount of the inorganic alkaline salt can be selected so as to maintain the pH of the first composition within a range of 10 to 14. Maintaining a pH above 10 is not only an important factor in maximizing the chemical stability of the first composition, but also in enhancing the detergency of the surfactant. Furthermore, maintaining the pH of the first composition within a range of 10 to 14 helps minimize the chemical decomposition of the hypochlorite compound in the aqueous solution phase, as well as chemical interactions between the hypochlorite compound and the surfactant.

In the present invention, to reduce the strong odor of hypochlorite ions during use and to meet aesthetic requirements, a fragrance may be included in the foaming drainpipe cleaner. The fragrance may be a fragrance that is stable to hypochlorite ions and is used in an amount of 0.01 to 2% by weight relative to the total weight of the first composition.

As described above, the pH of the first composition of the present invention is preferably maintained at 10 to 14. Therefore, when the pH of the prepared first composition is outside this range, a pH adjuster may be used to adjust the pH to 10 to 14. Examples of the pH adjuster include citric acid, sodium hydroxide, calcium hydroxide, and triethanolamine.

In the present invention, the foaming drainpipe cleaner utilizes a second oxygen-based foaming composition to generate foam. This second composition may contain hydrogen peroxide as a main component, which reacts with the hypochlorite in the first composition to generate oxygen gas. Furthermore, the second composition may contain an anionic surfactant, a nonionic surfactant, or a mixture thereof to enhance cleaning effectiveness while maintaining a viscosity greater than 100 cps. Furthermore, a free radical stabilizer may be included to ensure stable flow of hydrogen peroxide.

The content of hydrogen peroxide can be 0.1 to 30% by weight, preferably 5 to 27% by weight, and more preferably 15 to 25% by weight relative to the total weight of the second composition. When the content of hydrogen peroxide is less than 0.1% by weight, the foaming effect and the resulting improvement in cleaning effect are minimal. When the content of hydrogen peroxide exceeds 30% by weight, the stability of the second composition is reduced, making it difficult to circulate.

In the present invention, it is very important for the second composition to stabilize hydrogen peroxide as its main component. To this end, the second composition may further include a free radical stabilizer. As the free radical stabilizer, salicylic acid represented by the following chemical formula 3 can be used, but is not limited thereto.

Chemical formula 3:

The content of the free radical stabilizer can be 0.01 to 15% by weight, preferably 0.1 to 5% by weight, and more preferably 0.5 to 3% by weight, relative to the total weight of the second composition. When the content of the free radical stabilizer is less than 0.01% by weight, the stabilization effect of hydrogen peroxide is insufficient, while when the content exceeds 15% by weight, the stability of the second composition is reduced.

In the present invention, the second composition may contain, in addition to the above-mentioned components, inorganic salts such as sodium carbonate and sodium sulfate, polymers, and fragrances generally used in cleaning compositions.

In the present invention, in order to enhance the bactericidal and disinfecting effects of hypochlorite ions and improve their cleaning effect and viscosity, the first composition and the second composition may each contain an anionic surfactant, a nonionic surfactant, or a mixture of the two.

The content of the anionic surfactant can be 0.1 to 10% by weight, preferably 0.5 to 7% by weight, relative to the total weight of the first composition or the second composition. The content of the nonionic surfactant can be 0.1 to 10% by weight, preferably 0.5 to 7% by weight, relative to the total weight of the first composition or the second composition. When the content of the anionic surfactant or nonionic surfactant is less than 0.1% by weight, its cleaning ability cannot be fully exerted, and it is difficult to form viscosity in the first composition or the second composition. When the content exceeds 10% by weight, the stability of hypochlorite ions or hydrogen peroxide will be hindered.

Preferably, the first composition and the second composition may each comprise a mixture of an anionic surfactant and a nonionic surfactant. More preferably, in the mixture, the weight ratio of the anionic surfactant to the nonionic surfactant may be 1:10 to 10:1, preferably 1:5 to 5:1, and more preferably 1:3 to 3:1 (anionic surfactant:nonionic surfactant). Within the above weight ratio range, the viscosity and cleaning ability are most effectively improved.

In the present invention, the content of the anionic surfactant, nonionic surfactant, or a mixture thereof may be 1 to 40% by weight, preferably 3 to 30% by weight, and more preferably 5 to 20% by weight, relative to the total weight of the cleaning agent. When the content of the surfactant is less than 1% by weight, the cleaning agent has a weak detergent function, while when it exceeds 40% by weight, the solubility of the cleaning agent may be reduced.

The anionic surfactant may include, for example, at least one selected from the group consisting of linear alkylbenzene sulfonates (R1- _CH2 - _SO3Na , wherein R1 represents a C9-C15 alkyl group), fatty acid salts (R2- _CH2 -COONa, wherein R2 represents a C11-C16 alkyl group), basic sulfonates (R3=CH- _SO3Na , wherein R3 represents a C11-C18 alkyl group), _and α-olefin sulfonates (R4-CH=CH- _CH2SO3Na , wherein R4 represents a C12-C18 alkyl group), but is not limited thereto.

The nonionic surfactant may include, for example, at least one selected from the group consisting of fatty alkoxypolyoxyethylene glycol (R5-CH-(O- _CH2 - _CH2 )l-OH, wherein R5 represents a C11-C18 alkyl group and l represents an integer of 5-25), fatty acid polyoxyethylene glycol (R6-CO-(O- _CH2 - _CH2 )m-OH, wherein R6 represents a C11-C18 alkyl group and m represents an integer of 5-25), alkylphenyl polyoxyethylene glycol (R7-Ar-O-( _CH2OCH2 - _O )nH, wherein R7 represents a C11-C18 alkyl group, Ar represents a benzene ring and n represents an integer of 5-25), and polyoxyethylene glycol (H-(O- _CH2 - _CH2 )i-OH, wherein i represents a total molecular weight of an integer of 1000 to 30000), but is not limited thereto.

The present invention may further comprise other optional components within the scope not impairing the purpose of the present invention. In addition, in order to maintain the basic physical properties and quality of the cleaning composition, preservatives, thickeners, viscosity modifiers, fragrances, dyes, etc. that are generally and effectively used in cleaning compositions may also be included.

For example, as a preservative, a mixture of methylparaben, methylchloroisothiazolinone, and methylisothiazolinone (trade name: Kathon CG, manufacturer: Rohm and Haas Company, USA) can be used. As a thickener and viscosity modifier, hydroxypropyl methylcellulose, hydroxymethylcellulose, sodium chloride, ammonium chloride, propylene glycol, or hexylene glycol can be used. As a dye, a water-soluble tar pigment can be used.

In the present invention, the foaming drain cleaner may further include a thickener to slow down drainage. The viscosity of the cleaning composition containing the thickener may be 100 to 10,000 cps. Examples of the thickener include, but are not limited to, one or more selected from the group consisting of xanthan gum, locust bean gum, carrageenan, pectin, and gelatin.

The present invention also provides a foaming drain cleaner comprising a first composition and a second composition. The first composition comprises, relative to the total weight of the first composition, 0.1-30% by weight of a hypochlorite, 0.1-10% by weight of an anionic surfactant, 0.1-10% by weight of a nonionic surfactant, and 0.05-10% by weight of an inorganic alkali salt. The second composition comprises, relative to the total weight of the second composition, 0.1-30% by weight of hydrogen peroxide, 0.1-10% by weight of an anionic surfactant, 0.1-10% by weight of a nonionic surfactant, and 0.05-10% by weight of a free radical stabilizer. This foaming drain cleaner has excellent sterilizing and disinfecting effects on kitchen sink filters and drain pipes and has an excellent viscosity of over 100 cps.

Additionally, the first dose of the foaming drain cleaner may contain a pH adjuster, wherein the equivalent ratio of the pH adjuster to the total hydrogen ions of the acidic substance contained in the second dose (pH adjuster: equivalents of the total hydrogen ions of the acidic substance contained in the second dose) is 1.1 to 10:1. Alternatively, the first dose of the foaming drain cleaner may contain 0.3 to 10% by weight of the pH adjuster relative to the total weight of the first dose composition. In this case, the foaming drain cleaner significantly suppresses the generation of chlorine gas, making it safe for human health.

Furthermore, the foaming drain cleaner composition may contain the hypochlorite and hydrogen peroxide at an equivalent ratio (hypochlorite:hydrogen peroxide) of 1:1 to 10:1. In this case, the foaming drain cleaner composition significantly increases the amount of foam generated and exhibits excellent sterilization and disinfection effects on filters, drain outlets, and drain pipes.

The present invention also provides a foaming drain cleaning kit comprising the foaming drain cleaning container and the foaming drain cleaning agent. The kit can be used by a general user to conveniently and effectively clean the filter, drain outlet, and drain pipe of a kitchen sink.

Preferably, the present invention provides a drain pipe cleaning kit for foaming cleaning, characterized in that it comprises: a drain pipe cleaning agent for foaming cleaning, the drain pipe cleaning agent for foaming cleaning including a first agent containing hypochlorite and a second agent containing hydrogen peroxide; and a drain pipe cleaning container for foaming cleaning, the drain pipe cleaning container for foaming cleaning including a container body having a storage space formed therein and an inlet for allowing the drain pipe cleaning agent for foaming cleaning to flow into the storage space, and the volume of the storage space is smaller than the total volume of the drain pipe cleaning agent for foaming cleaning.

For the above-mentioned cleaning kit, when the cleaning container and the cleaning agent included therein are used simultaneously, since the storage space of the cleaning container is smaller than the total volume of the cleaning agent, the cleaning agent with rich foam will overflow and flow through the inlet, thereby effectively cleaning the filter and the drain outlet.

More specifically, the volume of the storage space can be smaller than the volume of the mixture of the first and second doses of the drain cleaner in a foaming state and the bubbles generated thereby. Therefore, the mixture of the first and second doses of the foaming drain cleaner or the bubbles generated thereby can overflow and flow through the inlet of the storage space, thereby effectively cleaning the filter and drain outlet. If the volume of the storage space is larger than the combined volume of the mixture of the first and second doses and the bubbles, the cleaning agent will not overflow through the inlet, and thus, the filter located above the cleaning container will not be adequately cleaned.

In the present invention, the volume ratio of the volume of the above-mentioned storage space and the volume of the above-mentioned foaming cleaning agent can be 1:1.01-5, preferably 1:1.05-3, and more preferably 1:1.1-2 (volume of the storage space: volume of the cleaning agent after foaming). When the volume of the foaming cleaning agent relative to the volume of the storage space is less than 1:1.01 (volume of the storage space: volume of the cleaning agent after foaming), the foaming cleaning agent will not overflow the container or will overflow in small amounts, so the cleaning effect will be weak. If the volume of the foamed cleaning agent relative to the volume of the storage space exceeds 1:5 (volume of the storage space: volume of the cleaning agent after foaming), there is a problem that the foamed cleaning agent will excessively overflow to the bottom of the sink around the drain outlet.

The present invention also provides a method for foaming and cleaning a kitchen sink filter and a drainpipe using the foaming drainpipe cleaning container. FIG2 shows the cleaning method of the present invention using the foaming drainpipe cleaning agent and the cleaning container.

The cleaning method comprises: step S1, installing the aforementioned foaming cleaning drainpipe cleaning container at the drain outlet; and step S2, simultaneously or sequentially pouring the aforementioned first and second cleaning agent compositions into the receiving space of the cleaning container. In step S2, when the first and second compositions are poured sequentially, the order of pouring is irrelevant.

In the above-mentioned method for foaming and cleaning the filter and drain pipe of a kitchen sink, after the above-mentioned step S2, foaming is caused by mixing the first composition and the second composition. The foam overflows from the inlet of the above-mentioned cleaning container to clean the filter, and the liquid foaming cleaning agent slowly flows out through the outlet, thereby continuously exerting a cleaning effect on the drain pipe. Therefore, the cleaning method of the present invention can effectively clean the filter and the drain pipe at the same time.

Effects of the Invention

The foaming drain cleaning container of the present invention allows the foam of the foaming cleaning agent to overflow onto the filter screen and drain outlet of the kitchen sink, thereby effectively cleaning them, and allows the foaming drain cleaning agent to slowly flow into the drain pipe, thereby continuously exerting a cleaning effect on the drain pipe.

In addition, the drain cleaning composition of the present invention, when containing a chlorine-based cleaning agent component and a foaming agent in a specific weight ratio, can generate abundant foam, thereby having a very excellent sterilization and cleaning effect on the filter screen, drain outlet and drain pipe of the sink.

In addition, when the drain cleaning composition of the present invention further contains a pH adjuster, the pH value when the first and second agents are mixed can be maintained at or above 9, thereby significantly suppressing the generation of chlorine gas caused by the reaction between the chlorine-based cleaning agent components and the foaming agent, thereby achieving a safe and excellent cleaning effect.

In addition, the foaming cleaning drain pipe cleaning kit of the present invention allows the foam of the foaming cleaning agent to overflow from the cleaning container, thereby effectively cleaning the filter screen and drain outlet of the kitchen sink.

DETAILED DESCRIPTION

Below, in order to help understand the present invention, the following embodiments will be described in detail. However, the embodiments of the present invention can be modified in various ways, and it should not be understood that the scope of the present invention is limited to the following embodiments. The embodiments of the present invention are provided to more fully illustrate the present invention to those of ordinary skill in the art.

Example: Manufacturing a foaming drain cleaning agent

The raw material components were mixed and stirred according to the composition ratios shown in Tables 1 and 2 below to produce a first composition and a second composition.

【Table 1】

First dose composition

Raw material name Weight ratio 1 purified water Add to 100 2 Sodium hypochlorite (12%) 20% 3 SLES (3 mol, 27%) 5% 4 Laurylamine oxide 1% 5 spices 0.1%

【Table 2】

Second dose composition

Raw material name Weight ratio 1 purified water Add to 100 2 Hydrogen peroxide (35%) 20% 3 SLES 5% 4 salicylic acid 1% 5 sodium sulfate 0.5% 6 spices 0.1%

The cleaning container was fabricated in the form of a cup, as shown in one embodiment of FIG5 . When the first and second compositions were used simultaneously with the cleaning container, it was confirmed that the foamable mixture of the first and second compositions overflowed through the inlet, cleaning the filter, and the foamable liquid composition was continuously discharged through the outlet provided through the cup.

Experimental Example 1: Evaluation of the Sterilization and Cleaning Capacity of Drain Outlets Using a Cleaning Container

Six households were visited and their sink drains were cleaned for 1.5 hours using the first and second doses of the present invention and a cup-shaped cleaning container. The number of microorganisms at the drain outlets was then measured. The experimental results, shown in Table 3 below, confirmed that an average of 99.93% of microorganisms in the drains were eliminated, demonstrating excellent sterilization effectiveness.

【Table 3】

Microbial killing rate before and after treatment

3 and 4 show photographs before cleaning (left) and after cleaning (right). It was confirmed that the foaming cleaning composition of the present invention and the cleaning container have excellent cleaning effects on the filter and the drain port.

Experimental Example 2: Evaluation of the sterilization and cleaning capabilities of drain pipes using cleaning containers

Seven households were visited. After cleaning the drain pipes of sinks for 1.5 hours using the first and second agents of the present invention and a cup-shaped cleaning container, the number of microorganisms in the drain pipes was evaluated.

In the Example, a cuvette was placed in a sink, 500 ml of the first dose was poured in, followed by 250 ml of the second dose, and then allowed to stand for 1.5 hours. In the Comparative Example, 500 ml of the first dose and 250 ml of the second dose were poured simultaneously into the sink and allowed to stand for 1.5 hours. A microbial sample was then collected and measured approximately 10 cm from the sink drainpipe entrance.

The experimental results shown in Table 4 below show that Comparative Examples 1 to 3, which did not use a cuvette, exhibited an average sterilization efficiency of 57.10%. In contrast, the drain pipes of Examples 1 to 4, which used a cuvette, exhibited an average sterilization efficiency of 99.95%. This confirms that the cuvette of the present invention exhibits a very excellent sterilization effect.

【Table 4】

6 and 7 show photographs of the comparative example before cleaning ( FIG. 6 ) and after cleaning ( FIG. 7 ), and FIG. 8 and 9 show photographs of the example before cleaning ( FIG. 8 ) and after cleaning ( FIG. 9 ). These results confirm that the foaming cleaning composition and drain cleaning container of the present invention provide a very excellent drain cleaning effect.

Experimental Example 3: Evaluation of the Diameter and Number of Discharge Ports on Discharge Time and Sterilization Capacity

To evaluate the effects of the diameter and number of discharge ports on discharge time and sterilization performance, the first and second doses were prepared according to the composition ratios listed in Tables 1 and 2. Subsequently, 500 ml of the first dose and 250 ml of the second dose were poured into cup-shaped cleaning containers having the corresponding discharge port sizes and numbers shown in Table 5. The time required for complete discharge was measured.

【Table 5】

The results shown in Table 5 above confirm that when the diameter of the discharge outlet is 1 to 2.5 mm and the number of outlets is 2 to 5 (Examples 10 to 12), the discharge time of the foaming cleaning agent is approximately 30 minutes to 2 hours. Furthermore, it was found that when the foaming composition is discharged for a time greater than 30 minutes, a microbial kill rate exceeding 99.9% is achieved, while after 2 hours, further enhanced sterilization performance is difficult to achieve.

Experimental Example 4: Chlorine Concentration after Mixing a Cleaning Composition Containing a pH Adjuster

The raw material components were mixed and stirred according to the composition ratios shown in Table 6 below to prepare first and second compositions of comparative examples and examples of the present invention.

The first and second compositions of Comparative Examples and Examples, prepared with different NaOH contents in the first composition, were mixed at a ratio of 1:1 and analyzed for pH and chlorine gas generation by gas chromatography.

【Table 6】

According to the experimental results shown in Table 6, it can be confirmed that, like Comparative Examples 4 and 5, when the NaOH content in the first agent is less than 0.2%, the pH value after mixing is less than 9, and a significant amount of chlorine gas is generated.

In contrast, the analysis results of chlorine gas generation in Example 13, shown in Figures 10 and 11, confirm that the chlorine gas concentration in Example 13 was 15.3 ppm, significantly lower than that in the Comparative Example. For reference, the chlorine gas concentration in Example 13 was significantly lower than the toxic concentration (LC50) of 293 ppm.

Experimental Example 5: Evaluation of the Bactericidal Ability of a Cleaning Composition Containing a pH Adjuster

Six households were visited and their sink drains were cleaned for 1.5 hours using 500 ml of the first dose and 500 ml of the second dose of the composition corresponding to Example 13 of the present invention, along with a cup-shaped reaction container having four holes with a diameter of 1 mm at the bottom. The number of microorganisms at the drain outlet was then measured.

【Table 7】

Microbial killing rate before and after treatment

According to the experimental results shown in Table 7, it was confirmed that an average of 99.93% of the microorganisms in the drainage pipe were killed, indicating an excellent sterilization effect.

Experimental Example 6: Evaluation of the amount of foam generated by cleaning agents based on the equivalent ratio of hypochlorite to hydrogen peroxide

【Table 8】

First dose composition

After preparing the first and second agents according to the compositions shown in Table 8 and Table 2, comparative examples and examples were prepared at the equivalent ratios shown in Table 9 below.

【Table 9】

First dose of sodium hypochlorite (mol) Second dose of hydrogen peroxide (mol) Comparative Example 6 0.79 1 Comparative Example 7 10.59 1 Example 16 1.26 1 Example 17 3.16 1 Example 18 5.53 1

After 500 ml of the first dose was poured into a 3500 mL beaker, 250 ml of the second dose was poured therein, and the amount of bubbles generated and the bubble bursting time were measured. The results are shown in Table 10 below.

【Table 10】

Evaluation results of foam volume and foam breaking time

Comparative Example 6 Comparative Example 7 Example 16 Example 17 Example 18 Initial foam volume 2500ml 1300ml 2400ml 2200ml 1900ml Bubble breaking time 150 minutes 40 minutes 140 minutes 120 minutes 70 minutes

The results shown in Table 10 above indicate that in Comparative Example 7, where the sodium hypochlorite equivalent ratio exceeded 10:1 (hypochlorite:hydrogen peroxide), the amount of foam generated initially was relatively small. Furthermore, since the foam burst time in Comparative Example 7 was also short, it is not suitable for situations where the cleaning composition remains in the drainpipe for an extended period of time and exhibits sufficient cleaning performance.

Experimental Example 7: Evaluation of the sterilization and cleaning capabilities of mixed solutions for drain pipes

The bactericidal and cleaning abilities of solutions prepared by mixing 500 ml of the first agent and 250 ml of the second agent from the comparative example and example of Experimental Example 6 were evaluated. Five households were visited and sink drains were cleaned for 1.5 hours using the first and second agent cleaning compositions and the cleaning container of the present invention. Afterwards, the number of microorganisms at the drain outlet was measured to confirm the degree of contamination removal.

【Table 11】

Microbial killing rate before and after treatment

Before treatment (CFU/mL) After treatment (CFU/mL) Killing rate (%) Comparative Example 6 5.6E+07 5.9E+06 89.46 Comparative Example 7 5.1E+07 4.8E+05 99.06 Example 16 3.1E+08 1.6E+05 99.95 Example 17 4.3E+07 1.9E+04 99.96 Example 18 7.7E+07 3.4E+04 99.96

The experimental results shown in Table 11 above confirm that when the sodium hypochlorite content in the first dose is low, that is, when the equivalent of sodium hypochlorite relative to the equivalent of hydrogen peroxide in the second dose is 0.79 times, as in Comparative Example 6, the amount of sodium hypochlorite remaining after the reaction between the first and second doses is small, resulting in a weak bactericidal effect. Furthermore, when the equivalent of sodium hypochlorite relative to hydrogen peroxide is high, that is, 10.59 times, as in Comparative Example 7, the bactericidal effect is not maximized because sufficient foam is not retained in the drainpipe.

In addition, after cleaning the drain outlets of the sinks of the visited households with the mixed solution of the first and second doses for 1.5 hours, the degree of contamination removal in the filters and drain pipes was visually confirmed. The cleaning performance evaluation results are shown in Table 12.

【Table 12】

(◎: Very good; ○: Good; △: Average; X: Not good)

Table 12 above confirms that when the sodium hypochlorite content in the first dose is low, that is, when the sodium hypochlorite equivalent to hydrogen peroxide is 0.79 times, as in Comparative Example 6, the cleaning performance is weak. Furthermore, in Comparative Example 7, although the sodium hypochlorite equivalent to hydrogen peroxide is high, namely 10.59 times, the cleaning foam does not sufficiently remain on the inner wall of the drainpipe, resulting in poor cleaning performance.

Experimental Example 8: Evaluation of the sterilization and cleaning capabilities of the mesh component of the cleaning container

We visited eight households, installed non-mesh cleaning containers in the sink drains of two households, and installed mesh cleaning containers in six households. We then treated the sink drains with both the first and second doses. After cleaning the sink drains for 1.5 hours, we measured the number of microorganisms in the drains.

The experimental results shown in Table 13 below confirm that an average of 99.87% of microorganisms were killed in drainpipes treated with cleaning agents using a cleaning container with a mesh member. These results confirm that the Example, treated with a cleaning container with a mesh member, exhibited significantly higher sterilization capabilities than the Comparative Example, treated with a cleaning container without a mesh member.

In addition, the degree of contamination removal was visually assessed, and the cleaning performance evaluation results are shown in Table 14 below. The results shown in Table 14 below confirm that the Examples exhibited superior cleaning performance overall compared to the Comparative Examples. These results confirm that the mixed solution of the first and second agents processed in the cleaning container formed dense foam as it passed through the mesh member. This foam adhered to the wall of the drainpipe, effectively removing contamination. [Table 14]
