Description

Technical Field

[0001] This application claims the benefit of priority based on Korean Application No. 10-2017-0146817, filed on November 6, 2017, and Korean Application No. 10-2017-0147519, filed on November 7, 2017, and all contents disclosed in the specification and drawings of this application are incorporated herein by reference.

[0002] The present invention relates to a drain cleaning sprayer, and more particularly to a drain cleaning sprayer that sprays a drain cleaning composition toward a drain outlet and drain pipe of a sink to achieve an excellent foaming cleaning effect.

[0003] The present invention also relates to a method for cleaning a sink drain pipe and a cleaning container therefor, and more particularly to a method for cleaning and sterilizing a sink drain pipe by injecting a mixed foaming cleaning agent into the sink drain pipe and a cleaning container therefor. Background Art

[0004] Sink filters and drain pipes typically retain food during cooking and discarding, and since they are constantly wet, they foster microbial growth, leading to contamination and severe odors. However, cleaning these filters and drain pipes to maintain their cleanliness is inconvenient, time-consuming, and labor-intensive, and there are no specific solutions other than replacing them, creating a problem.

[0005] To address this issue, U.S. patent application Ser. No. 14 / 529,388 discloses a two-component system for cleaning drainpipes using a perhydrolase such as amylase to foam hydrogen peroxide. However, in this system, the bactericidal bleaching power of hydrogen peroxide is significantly lower than that of sodium hypochlorite, and thus the bactericidal bleaching effect is not fully achieved.

[0006] Additionally, U.S. Patent Publication No. US2003 / 0171234 discloses a method for cleaning drainpipes by simultaneously pouring a viscous sodium hypochlorite composition and a foaming agent to generate foam. However, this cleaning method is difficult to uniformly mix the sodium hypochlorite and foaming agent, and the foam cannot remain in the vertically disposed drainpipe for a long time and must be immediately discharged, thus limiting its cleaning power. Therefore, there is a need to develop a composition or method that increases the duration of the cleaning effect of a foaming cleaning agent composition and allows for more effective cleaning of drainpipes in sinks. Summary of the Invention

[0007] Technical issues

[0008] The problem to be solved by the present invention is to provide a drain pipe cleaning sprayer that sprays foam onto a drain outlet and drain pipe of a sink to achieve a foaming cleaning effect.

[0009] Another object of the present invention is to provide a method for foaming and cleaning a sink drain outlet and a drain pipe using a drain pipe cleaning sprayer.

[0010] In addition, the problem to be solved by the present invention is to provide a sink drain pipe cleaning method and a cleaning container for cleaning the sink drain pipe, which are improved by utilizing the combined structure of the first storage part and the second storage part to conveniently mix and foam the cleaning agent to clean the sink drain pipe.

[0011] In addition, the present invention aims to provide a method for cleaning a drain pipe of a sink, which allows foam to remain in the drain pipe of a vertically arranged sink for a long time to increase the duration of the cleaning effect achieved by the foaming cleaning agent, and a cleaning container for cleaning the drain pipe of a sink.

[0012] Means of solving problems

[0013] Furthermore, the present inventors have made unremitting efforts and research to overcome the above-mentioned problems in the prior art. As a result, they discovered that when a drain cleaner composition is sprayed onto a sink filter, drain outlet, and drain pipe using a sprayer, the foamed cleaner composition remains in the filter, drain outlet, and drain pipe for a long time, thereby maximizing the cleaning effect. This led to the completion of the present invention.

[0014] The present invention provides a drain cleaning sprayer comprising a drain cleaning composition including a chlorine-based cleaning agent. The sprayer sprays the drain cleaning composition into a drain outlet and drain pipe, providing a long-term cleaning effect on the filter, drain outlet, and drain pipe. The sprayer sprays the drain cleaning composition in a spray or foam form.

[0015] In the present invention, "spray" means spraying a liquid drain cleaner composition sealed together with liquefied gas in a sealed container by using gas pressure to disperse small droplets of the liquid in the gas.

[0016] In the present invention, a drain cleaning sprayer can be used that sprays the drain cleaning agent composition contained in the container in the form of a spray or foam through a spray port when unsealed. The container of the drain cleaning sprayer of the present invention is made by filling a sealable, flexible inner container with a drain cleaning agent composition. The container of the sprayer is composed of an outer container formed of iron, aluminum, or plastic, and an inner container containing the drain cleaning agent composition. LPG, DME, compressed nitrogen, or compressed air is filled between the outer container and the inner container to spray the drain cleaning agent composition under internal container pressure. In the container of the sprayer, the upper end of the outer container is sealed by a valve, and when the valve is unsealed and used, the drain cleaning agent composition in the inner container is continuously sprayed for a predetermined time.

[0017] In the present invention, the chlorine-based cleaning agent component may include hypochlorite, which has excellent bactericidal and bleaching effects, rapidly decomposes when diluted, leaves little residual residue, and has low oral toxicity. It can be effectively used for cleaning, sterilizing, and disinfecting sink filters, drain outlets, and drain pipes. More specifically, the hypochlorite may include at least one selected from the group consisting of sodium hypochlorite, potassium hypochlorite, calcium hypochlorite, and magnesium hypochlorite, but the present invention is not limited thereto. Preferably, sodium hypochlorite is used as the chlorine-based cleaning agent component.

[0018] The chlorine-based cleaning agent component preferably contains 0.1 to 30% hypochlorite by weight, preferably 5 to 27% hypochlorite by weight, and more preferably 15 to 25% hypochlorite by weight, relative to the total weight of the composition. When hypochlorite is used in an amount of 0.1% or less by weight, its bactericidal or disinfectant properties are weak, while when it exceeds 30% by weight, its compatibility with surfactants is poor, which is also disadvantageous in terms of the safety of the hypochlorite ion itself.

[0019] In the present invention, the cleaning composition includes an anionic surfactant, a nonionic surfactant, or a mixture thereof to enhance the bactericidal or disinfecting power of hypochlorite ions and improve cleaning performance and viscosity. Preferably, the anionic surfactant includes an alkyl ether sulfate of the following chemical formula 1, preferably SLES (sodium laurylether sulfate).

[0020] [Chemical Formula 1]

[0021] R(CH2CH2O) n SO3M

[0022] (The above R represents C 10 ~C 16alkyl, n represents an integer of 1 to 5, and M represents sodium or potassium)

[0023] 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, the alkylamine oxide of the following Chemical Formula 2 may be lauramine oxide.

[0024] [Chemical Formula 2]

[0025]

[0026] (The above R' represents C 10 ~C 16 alkyl)

[0027] In the present invention, a mixture of the above-mentioned alkyl ether sulfate and alkylamine oxide is used as an anionic surfactant. This provides superior cleaning power and viscosity compared to the case where each is used alone, due to the synergistic effect between the surfactants and the interaction with the surfactant and hypochlorite.

[0028] Preferably, the weight ratio of the alkyl ether sulfate to the alkyl amine oxide is 1:20 to 20:1, more preferably 1:10 to 10:1, and more preferably 1:1 to 10:1 (alkyl ether sulfate:alkyl amine oxide). When the alkyl ether sulfate and alkyl amine oxide are used within this weight ratio range, the viscosity of the cleaning composition of the present invention is optimal.

[0029] In the present invention, the anionic surfactant, nonionic surfactant, or mixture thereof comprises 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 detergent. If the surfactant content is less than 1% by weight, the detergent performance is poor, while if it exceeds 40% by weight, the solubility of the detergent decreases.

[0030] The cleaning composition of the present invention may further include any optional ingredients, including preservatives, thickeners, viscosity modifiers, fragrances, dyes, etc., which are commonly and effectively used in cleaning compositions, to maintain the basic physical properties and quality of the cleaning composition, without impairing the purpose of the invention.

[0031] In the present invention, the drain cleaning composition may additionally include a fragrance to reduce the strong odor of hypochlorite ions during use and to satisfy aesthetic needs. The fragrance can be a fragrance that is stable to hypochlorite ions, and the amount used is 0.01 to 2% by weight relative to the total weight of the cleaning composition.

[0032] Preservatives include, for example, methyl paraben, a mixture of methylchloroisothiazolinone and methylisothiazolinone (trade name: Kathon CG, manufactured by Rohm & Haas, USA). Thickeners and viscosity modifiers include hydroxypropyl methylcellulose, hydroxymethylcellulose, sodium chloride, ammonium chloride, propylene glycol, and hexylene glycol. Dyes include water-soluble tar pigments.

[0033] In the present invention, the drain cleaning composition further includes a thickener to slow down the rate of drainage. The viscosity of the cleaning composition including the thickener is 100 to 10,000 cps. Examples of the thickener include, but are not limited to, one or more selected from the group consisting of acrylic polymers, xanthan gum, locust bean gum, carrageenan, pectin, and gelatin.

[0034] The drain cleaning agent composition used in the drain cleaning sprayer of the present invention may not substantially contain a foaming agent. Preferably, the drain cleaning agent composition includes less than 5% by weight of a foaming agent relative to the total weight of the composition, more preferably includes less than 1% by weight of a foaming agent, more preferably includes less than 0.1% by weight of a foaming agent, and most preferably includes no foaming agent. The drain cleaning sprayer of the present invention does not substantially contain a foaming agent, thereby preventing the neutralization of the chlorine-based cleaning agent composition without hindering the cleaning power. In addition, the drain cleaning sprayer of the present invention can achieve a sufficient foaming effect simply by spraying, without the need for an unnecessary foaming process caused by a foaming agent, thereby minimizing the loss of cleaning ingredients.

[0035] In the present invention, a drain cleaning sprayer can be used that, upon opening, sprays the drain cleaning composition contained within the container in a spray or foam form through a spray port at a specific pressure. Preferably, the drain cleaning sprayer of the present invention is configured to continuously spray the drain cleaning composition within the container for a predetermined period of time upon opening until the drain cleaning composition within the container is completely consumed.

[0036] In the sprayer of the present invention, the container has a compression force of 3 to 9 bar, preferably 4 to 7 bar. If the compression force of the sprayer container is less than 3 bar, the cleaning composition is not discharged with sufficient force, resulting in weak cleaning power. If the compression force exceeds 9 bar, the cleaning composition is discharged rapidly, which may reduce the duration of cleaning.

[0037] The spray nozzle of the container of the sprayer of the present invention is preferably coupled to the inlet of the drain outlet. When using a sprayer of this configuration, the foaming cleaning composition discharged from the sprayer does not overflow from the drain outlet and drain pipe, but remains there for a long time, thereby effectively cleaning the drain outlet and drain pipe for a predetermined period of time.

[0038] Regarding the predetermined time, the sprayer of the present invention adjusts the amount and duration of the foaming cleaning composition discharged by adjusting the valve and nozzle of the container. The discharge time of the sprayer of the present invention is adjusted to discharge the cleaning composition for approximately 1 to 10 minutes, preferably 1.5 to 8 minutes, and more preferably 2 to 5 minutes. If the discharge time is less than 1 minute, the foamed cleaning composition will have difficulty filling the drain outlet and drain pipe. If it exceeds 10 minutes, the cleaning composition will be discharged excessively, resulting in waste.

[0039] To maximize cleaning effectiveness, the discharged foamed cleaning composition should be left in the drain outlet and drainpipe for 10 to 180 minutes, preferably 20 to 150 minutes, and more preferably 30 to 120 minutes. If the sprayed cleaning composition is left in place for less than 10 minutes, the composition will not remain in place for long enough, resulting in a weak cleaning effect. If the cleaning time exceeds 180 minutes, the excessive increase in cleaning time can lead to problems such as chlorine gas generation and sink corrosion.

[0040] The present invention also provides a method for cleaning a drain outlet and a drain pipe using the drain pipe cleaning sprayer.

[0041] Preferably, in the cleaning method of the present invention, the drainpipe cleaning sprayer is connected to the inlet of the drain outlet to discharge the cleaning agent for a predetermined time ( Figure 10 In the above cleaning method, the predetermined time applies in the same manner as described above for the sprayer of the present invention. This method produces denser foam than the foaming method of pouring one or two doses. When the cleaning composition is sprayed, the foamed cleaning composition, generated by the higher pressure, is delivered into the drainpipe, fully filling the drainpipe. Thus, the cleaning method of the present invention prevents the cleaning composition from overflowing from the drain outlet and drainpipe and remaining there for an extended period, maximizing the cleaning effect on the drain outlet and drainpipe.

[0042] In addition, in order to achieve the above-mentioned purpose, the present invention provides a method for cleaning the drain pipe of a sink, which includes the following steps: (a) preparing a cleaning container, which includes a first receiving part and a second receiving part for respectively receiving agent 1 and agent 2; (b) mixing the above-mentioned agent 1 and the above-mentioned agent 2 with each other; and (c) placing the above-mentioned cleaning container at the drain pipe inlet of the sink, and injecting the mixed foaming cleaning agent discharged through the discharge port of the above-mentioned cleaning container into the above-mentioned drain pipe.

[0043] In the above step (a), a cleaning container is prepared that includes a first storage portion and a second storage portion for storing agent 1 and agent 2 in an isolated manner. In the above step (b), physical force is applied to damage the isolation portion between the above first storage portion and the above second storage portion to mix the above agent 1 and the above agent 2 with each other.

[0044] In the step (b), the separator is broken by a physical force generated by screwing or pressing, thereby mixing the first agent and the second agent.

[0045] In the step (a), the first and second storage parts are separated from each other, and in the step (b), the first and second agents are mixed with each other as the first and second storage parts are coupled together.

[0046] One of the first and second agents is in powder form, and the other is in liquid form.

[0047] In the step (c), the cleaning container is placed in an inverted state to inject the mixed foaming cleaning agent into the drain pipe.

[0048] According to another aspect of the present invention, a cleaning container for drain pipe cleaning is provided, characterized in that it includes: a first receiving portion and a second receiving portion, which respectively receive agent 1 and agent 2; and a rupture portion, which is provided in any one of the above-mentioned first receiving portion and the above-mentioned second receiving portion, so that the above-mentioned first receiving portion and the above-mentioned second receiving portion are combined with each other, and when physical force is applied, at least the other one is ruptured, so that the above-mentioned agent 1 and the above-mentioned agent 2 are mixed with each other, and the combination of the above-mentioned first receiving portion and the above-mentioned second receiving portion is arranged at the drain pipe inlet of the sink, thereby injecting a mixed foaming cleaning agent generated by the mixture of the above-mentioned agent 1 and the above-mentioned agent 2 into the above-mentioned drain pipe.

[0049] In one embodiment, in the drain cleaning container of the present invention comprising a first storage portion and a second storage portion and the drain cleaning method using the drain cleaning container, the above-mentioned first and second agents are mixed and then sprayed through the drain cleaning spray injector of the present invention for use.

[0050] Effects of the Invention

[0051] The drain cleaning sprayer of the present invention sprays the drain cleaning composition onto the sink filter, drain outlet and drain pipe in the form of spray or foam, and allows the foamed cleaning agent to stay for a long time, thereby maximizing the cleaning effect.

[0052] In addition, according to the present invention, the first and second agents are conveniently mixed and foamed by utilizing the coupling structure between the first and second housing parts, thereby having the advantage of being easy to handle and use.

[0053] In addition, the mixed foaming cleaning agent is slowly released from the inverted cleaning container, so that the foam stays in the drain pipe of the sink for a long time, thereby increasing the duration of the cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0065] Below, to facilitate understanding of the present invention, embodiments and the like are described in detail. However, the embodiments of the present invention may be modified into various forms, and the scope of the present invention is not limited to the following embodiments. The embodiments of the present invention are provided to more fully illustrate the present invention to those skilled in the art.

[0066] Example: Preparation of a Drain Cleaner Composition for Use in a Sprayer

[0067] The raw material components were mixed in the composition ratio shown in Table 1 below to produce a drain cleaning agent composition to be used in a sprayer.

[0068] Table 1

[0069]

[0070] The drainpipe cleaning composition and compressed gas were filled into a container at a pressure of 5 bar to produce a sprayer. In the following experimental examples, the comparative examples had the same ingredients as the examples, but used a liquid composition instead of a spray.

[0071] Experimental example: Evaluation of the sterilization and cleaning power of drain outlets

[0072] Ten households were visited and their sink drains were cleaned using the drainpipe cleaning sprayer of the present invention. Specifically, the spray can of the present invention was placed upside down and attached to the drain. The cleaning composition was sprayed for approximately 2-5 minutes, and then left to stand for approximately 1.5 hours to ensure the cleaning effect. After cleaning, the number of microorganisms in the filter and drain outlet was evaluated. Microorganism counts were measured at a point 15 cm from the drain outlet entrance to the bottom of the drainpipe.

[0073] The spray-type example was slowly discharged as foam, demonstrating an excellent sterilization rate of over 99.9% in both the filter and drain. In contrast, the liquid-type comparative example failed to remain in the filter and drain for long and immediately remained, resulting in insufficient sterilization.

[0074] Table 2

[0075]

[0076] in addition, Figure 1 It is a combined cross-sectional view showing the structure of a cleaning container for performing a method for cleaning a drain pipe of a sink according to a preferred embodiment of the present invention.

[0077] Reference Figure 1 According to a preferred embodiment of the present invention, a cleaning container is provided, which includes: a container body 100, a first receiving portion 101 and a second receiving portion 102 coupled to the container body 100; a partition 103 located between the first receiving portion 101 and the second receiving portion 102; a cover 105 screwed to the upper portion of the container body 100 to cover the opening; and a rupture portion 104, which ruptures the partition 103 by a physical force generated by the screwing of the cover 105.

[0078] The container body 100 comprises a first storage portion 101 and a second storage portion 102 for storing a first dose 10 and a second dose 20, respectively, connected to form a single body. The shape of the container body 100 is not limited to the example shown in the drawings, but can be variously modified.

[0079] The first storage portion 101 for storing the first agent 10 is relatively close to the upper end of the container body 100 compared to the second storage portion 102 for storing the second agent 20. The first storage portion 101 is preferably inserted into the interior of the second storage portion 102 and fixed. In such a configuration structure, it is preferred that the first agent 10 is formed into a powder form and the second agent 20 is formed into a liquid form, but it is not limited to such an example. That is, the first agent 10 and the second agent 20 can be in various forms selected from liquid, powder, tablets, etc. When the first agent 10 and the second agent 20 are mixed with each other, a foaming cleaning agent that can clean and sterilize the drain pipe of the sink is formed. As the composition of the first agent 10 and the second agent 20, a general product can be used, so its detailed description is omitted.

[0080] A through-hole discharge port 102a for discharging the foaming detergent is formed on the side of a portion near the upper end of the second housing portion 102 (preferably, the portion where the screw is formed). This discharge port 102a is exposed when the lid 105 is removed from the second housing portion 102 and raised a predetermined distance, and communicates with the gap 106 through which the mixed foaming detergent is discharged.

[0081] The separator 103 is located between the first storage section 101 and the second storage section 102 to separate the first dose 10 from the second dose 20. The separator 103 is formed by a member (e.g., a film) independent of the first storage section 101 or the second storage section 102, or may be formed by the bottom portion of the first storage section 101.

[0082] The rupture portion 104 is integrated with a cover 105 of a predetermined shape and linked together. Figure 2As shown, the physical force generated by the cap 105 being screwed onto the container body 100 and advancing downward causes the rupture portion 104 to rotate, rupturing the separator 103, thereby mixing the first dose 10 and the second dose 20. The tip of the rupture portion 104 is substantially sharp or pointed to rupture the separator 103. Preferably, the rupture portion 104 is cylindrical in shape to rupture the separator 103 over a wide area as much as possible, with one side being relatively longer, forming a sharp structure. As a countermeasure, the rupture portion 104 can also be configured as a rod with a sharp tip.

[0083] like Figure 3 As shown, when the lid 105 is retracted a predetermined distance, a gap 106 communicating with the outside is formed between the lid 105 and the second housing portion 102. Therefore, the mixed foaming cleaning agent formed by mixing the first agent 10 and the second agent 20 is gradually released to the outside of the container body 100 through the gap 106.

[0084] In a cleaning container having such a structure, when the user intentionally rotates the lid 105 in the closing direction, the rupture portion 104 advances and ruptures the partition 103, thereby releasing the separation between the first agent 10 and the second agent 20. When the partition 103 ruptures, the powdered first agent 10 in the first storage portion 101 and the liquid second agent 20 in the second storage portion 102 mix with each other to form a foaming cleaning agent.

[0085] After the foaming detergent is produced by mixing the first agent 10 and the second agent 20, when the lid 105 is gently rotated in the opening direction, the mixed foaming detergent is converted into a state of being discharged to the outside through the discharge port 102a and the gap 106 between the container body 100 and the lid 105 connected thereto.

[0086] like Figure 4 As shown, when the cleaning container is placed upside down at the drain inlet 200 of the sink so that the mixed foaming cleaning agent can be discharged to the outside, the mixed foaming cleaning agent is slowly injected through the inlet hole 201 of the drain pipe over a long period of time, thereby performing cleaning and sterilization treatment.

[0087] Figure 5 1 is an exploded perspective view showing the structure of a cleaning container for cleaning a drain pipe of a sink provided according to another embodiment of the present invention. Figure 6 yes Figure 5 Combined cross-sectional view.

[0088] Reference Figure 5 and Figure 6According to another embodiment of the present invention, a cleaning container is provided, which includes: a container body 100', a first receiving portion 101' and a second receiving portion 102' coupled to the container body 100'; a partition 103' located between the first receiving portion 101' and the second receiving portion 102'; a cover 105' screwed to the upper portion of the container body 100' to cover the opening; and a rupture portion 104' which ruptures the partition 103' by a physical force generated by a push operation of a user.

[0089] The first storage section 101' is located relatively closer to the upper end of the container body 100' than the second storage section 102'. To this end, the first storage section 101' is preferably screwed into the upper portion of the second storage section 102'. A through-hole outlet 101'a is preferably formed on the side of the first storage section 101' for discharging the mixed foaming detergent. This outlet 101'a communicates with the outside when the first storage section 101' separates from the second storage section 102' and rises a predetermined distance.

[0090] Preferably, the first agent 10 stored in the first storage section 101' is in powder form, and the second agent 20 stored in the second storage section 102' is in liquid form, but this is not limiting. Specifically, the first agent 10 and the second agent 20 can take various forms, including liquids, powders, and tablets. When the first and second agents 10 and 20 are mixed, a foaming detergent is formed that can clean and sterilize sink drain pipes. Since the combination of the first and second agents 10 and 20 can be a common product, a detailed description thereof will be omitted.

[0091] The separator 103' is located between the first storage section 101' and the second storage section 102' to separate the first dose 10 and the second dose 20. The separator 103' is formed of a member (e.g., a film) independent of the first storage section 101 or the second storage section 102, or may be formed by the bottom portion of the first storage section 101'.

[0092] The rupture portion 104' is separated from the cover 105' and is connected to the first receiving portion 101' in a state of being more or less tightly inserted. Figure 7As shown, when an external force is applied to the upper end of the rupture portion 104' with the cover 105' removed, the rupture portion 104' slides and advances downwardly of the first storage portion 101'. Through such physical force, the rupture portion 104' ruptures the isolation portion 103', and as the isolation state is released, the first dose 10 and the second dose 20 are mixed with each other. Preferably, the top end of the rupture portion 104' is substantially formed in a pointed or sharp shape so as to be able to rupture the isolation portion 103', and the rupture portion 104' is formed in a cylindrical shape so as to rupture one isolation portion 103' to a wide area as much as possible, and one side is formed to be relatively longer to form a sharp structure. As a countermeasure, the rupture portion 104' can be configured in the shape of a rod with a sharp tip.

[0093] like Figure 8 As shown, when the screws of the first container 101' are loosened and the container extends a predetermined distance from the second container 102', the discharge port 101'a is exposed to the outside. This connects the container body 100' to the outside. Consequently, the mixed foaming detergent, formed by mixing the first agent 10 and the second agent 20, is gradually discharged through the discharge port 101'a to the outside of the container body 100'.

[0094] In the case of a cleaning container having the above-described structure, if a user presses the upper end of the rupture portion 104' while the lid 105' is removed, the rupture portion 104' advances, rupturing the separator 103', thereby releasing the separation between the first agent 10 and the second agent 20. When the separator 103' is ruptured, the powdered first agent 10 in the first storage portion 101' and the liquid second agent 20 in the second storage portion 102 mix together to form a foaming cleaning agent.

[0095] After the foaming detergent is produced by mixing the first agent 10 and the second agent 20, the first container 101' is rotated in an opening direction to slightly expose the discharge port 102'a to the outside, so that the mixed foaming detergent flows from the container body 100' and is discharged to the outside.

[0096] like Figure 9 As shown, when the cleaning container is placed upside down at the drain inlet 200 of the sink while the mixed foaming cleaning agent is being released to the outside, the mixed foaming cleaning agent is slowly injected through the inlet hole 201 of the drain pipe over a long period of time, thereby performing cleaning and sterilization.

[0097] Figure 10 A combination structure of a cleaning container for performing a method for cleaning a drain pipe of a sink according to yet another embodiment of the present invention is shown.

[0098] exist Figure 10In (a), the first storage section 110 and the second storage section 120 store the first and second doses separately, respectively, similarly to the above-mentioned embodiment, and provide them in a state of being separated from each other.

[0099] like Figure 10 As shown in (b), during use, when the second storage part 120 is coupled to the first storage part 110 to complete the connection, the isolation part 111 of the first storage part 110 is ruptured by the rupture part 125 provided in the second storage part 120, thereby connecting the first storage part 110 and the second storage part 120 to each other, thereby mixing the first agent and the second agent to form a foaming detergent. At this time, the isolation part 111 of the first storage part 110 is inserted into the first storage part 110 by the rupture part 125 of the second storage part 120 according to the physical force generated by the screwing or pressing operation and is ruptured. As a countermeasure, a predetermined isolation part (isolation membrane) is provided at the top of the second storage part 120, and is damaged and ruptured during the insertion process, so that the two agents stored therein are discharged and mixed with the first agent stored in the first storage part 110.

[0100] If the cleaning container is placed at the drain inlet 200 of the sink with the first storage section 110 and the second storage section 120 combined, the mixed foaming cleaning agent is slowly discharged over a long period of time through the gap between the first storage section 110 and the second storage section 120, and is then injected through the inlet hole 201 of the drain to perform cleaning and sterilization.

[0101] The present invention has been described above with reference to the limited embodiments and drawings, but the present invention is not limited thereto, and those skilled in the art can make various modifications and variations within the technical concept of the present invention and the equivalent scope of the claims described below.

Claims

1. A method for cleaning a drain pipe of a sink, comprising the following steps: (a) Preparing a cleaning container including a container body, a partition, and a lid, wherein the container body includes a first storage portion and a second storage portion, wherein the first storage portion and the second storage portion respectively store a first dose and a second dose, the first storage portion and the second storage portion are separated from each other, and the second storage portion includes: a thread formed on an outer surface of the second receiving portion; and a discharge port formed between at least one of the threads, the isolation portion being located between the first receiving portion and the second receiving portion and being used to isolate the first receiving portion from the second receiving portion, the cap comprising a rupture portion extending along the axial direction of the container body toward the isolation portion, the cap being screwed to the container body to seal the container body; (b) rotating the lid in the first direction relative to the container body so that the lid is more screwed into the second receiving portion, thereby rupturing the separator through the rupturing portion, thereby mixing the first agent and the second agent to form a foaming detergent; (c) rotating the cover in a second direction opposite to the first direction to loosen the cover, wherein when the cover is rotated in the second direction and retreated a predetermined distance, a gap communicating with the outside is formed between the cover and the second receiving portion, the discharge port is exposed and communicated with the gap, and the foaming cleaning agent is slowly discharged to the outside of the container body through the gap; and (d) The cleaning container having the lid screwed to the container body is placed upside down at the drain inlet of the sink, and the foaming cleaning agent is discharged into the sink through the discharge port of the second storage portion, thereby cleaning the drain port of the sink.

2. The method for cleaning the drain pipe of a sink according to claim 1, wherein: One of the first and second agents is in powder form, and the other is in liquid form.

3. A cleaning container for cleaning the drain pipe of a sink, characterized in that: It includes: A container body comprising a first receiving portion and a second receiving portion for receiving a first dose and a second dose, respectively, wherein the first receiving portion and the second receiving portion are separated from each other, and the second receiving portion comprises: a thread formed on an outer surface of the second receiving portion; and a discharge port formed between at least one of the threads; an isolation portion located between the first receiving portion and the second receiving portion, for isolating the first receiving portion from the second receiving portion; and a cap including a rupture portion extending along the axial direction of the container body toward the isolation portion, the cap being screwed to the container body to seal the container body, The container body is rotated in the first direction to further screw the lid into the second receiving portion, thereby rupturing the separator through the rupture portion, thereby mixing the first agent and the second agent to form a foaming detergent. The lid is rotated in a second direction opposite to the first direction to loosen the lid. When the lid is rotated in the second direction and retreated a predetermined distance, a gap communicating with the outside is formed between the lid and the second receiving portion. At this time, the discharge port is exposed and communicated with the gap, and the foaming cleaning agent is slowly discharged to the outside of the container body through the gap. The cleaning container having the lid screwed to the container body is placed upside down at the drain inlet of the sink, and the foaming cleaning agent is discharged into the sink through the discharge port of the second storage portion, thereby cleaning the drain of the sink.
