Description

Technical Field

[0001] The present invention relates to an aerosol spray for cleaning drain pipes, and more particularly, to an aerosol spray for cleaning drain pipes that injects a drain pipe cleaning agent composition into a sink drain and a drain pipe to achieve an excellent foaming cleaning effect.

[0002] 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 injecting a mixed foaming cleaning agent into a sink drain pipe to perform cleaning and sterilization treatment and a cleaning container therefor.

[0003] This application claims priority based on Korean Patent Application No. 10-2017-0146817 filed on November 6, 2017 and Korean Application No. 10-2017-0147519 filed on November 7, 2017, and all of the contents disclosed in the specifications and drawings of the corresponding applications are incorporated herein.

Background Art

[0004] Generally, the garbage receiver and drain pipe of a kitchen sink are in an environment where food residues remain during the process of cooking or discarding food, are constantly wet with water, and microorganisms easily multiply. Therefore, they are easily soiled and cause bad odors. However, cleaning these to maintain cleanliness is inconvenient, time-consuming, and labor-intensive, and there is no special alternative other than replacing the garbage receiver and drain pipe, which has become a problem.

[0005] To solve this problem, U.S. Patent Application No. 14 / 529,388 discloses a two-component system that foams hydrogen peroxide with a hydrolytic enzyme such as amylase to clean pipes. However, such a system has a problem in that the bactericidal and bleaching power of hydrogen peroxide is significantly lower than that of sodium hypochlorite, and the bactericidal and bleaching effect cannot be fully exerted.

[0006] In addition, U.S. Patent Application Publication No. 2003 / 0171234 discloses a method of cleaning pipes by simultaneously pouring a viscous sodium hypochlorite composition and a foaming agent to cause foaming. However, in such a cleaning method, it is difficult to uniformly mix sodium hypochlorite and the foaming agent, and the foam does not stay in the pipes of a vertically installed sink for a long time and is immediately discharged, so there is a limit to maintaining the cleaning power.

[0007] Therefore, in order to more effectively clean the sink drain pipe, it is necessary to develop a composition or method that can extend the duration of the cleaning effect of the foaming cleaning agent.

Summary of the Invention

Problems to be Solved by the Invention

[0009] An object of the present invention is to provide an aerosol spray for cleaning drain pipes that can be sprayed onto a sink drain opening and a drain pipe to exhibit a foaming cleaning effect.

[0010] Another object of the present invention is to provide a method of foaming and cleaning a sink drain opening and a drain pipe using the aerosol spray for cleaning drain pipes.

[0011] Still another object of the present invention is to provide a method for cleaning a sink drain pipe and a cleaning container therefor, which are improved so that the cleaning agent can be conveniently mixed and foamed using the coupling structure between the first storage part and the second storage part to enable cleaning treatment of the sink drain pipe.

[0012] Furthermore, another object of the present invention is to provide a method for cleaning a sink drain pipe and a cleaning container therefor, which can increase the duration of the cleaning effect of a foaming cleaning agent by allowing bubbles to remain in a vertically provided sink pipe for a long time.

Means for Solving the Problems

[0013] As a result of intensive research to solve the above problems, the present inventors have found that when a drain pipe cleaning agent composition is sprayed onto the sink garbage receiver, drain opening, and drain pipe with an aerosol spray, the foamed cleaning agent composition remains in the garbage receiver, drain opening, and drain pipe for a long time, thereby maximizing the cleaning effect, and thus completing the present invention.

[0014] The present invention provides an aerosol spray for cleaning a drain pipe, which contains a drain pipe cleaning agent composition containing a chlorine-based cleaning agent component. By spraying the drain pipe cleaning agent composition onto the drain opening and drain pipe, the aerosol spray can clean the garbage receiver, drain opening, and drain pipe for a long time, and the cleaning effect is very excellent. The aerosol spray of the present invention can spray the drain pipe cleaning agent composition in the form of an aerosol or foam.

[0015] In the present invention, "aerosol" means a system in which a liquid drain pipe cleaning agent composition enclosed together with a liquefied gas in a sealed container is blown out by the pressure of the gas and small droplets are dispersed in the gas.

[0016] In the present invention, for the aerosol spray for cleaning drain pipes, a container that sprays the drain pipe cleaning agent composition contained inside the container in the form of an aerosol or foam from the spray port when opened can be used. The aerosol spray container for cleaning drain pipes of the present invention can be manufactured by filling a flexible inner container capable of sealing the drain pipe cleaning agent composition. The container of the aerosol spray may be composed of an outer container made of iron, aluminum, plastic, etc. and an inner container containing the drain pipe cleaning agent composition. Between the outer container and the inner container, LPG, DME, compressed nitrogen, compressed air, etc. that have an internal pressure of the container so that the drain pipe cleaning agent composition can be sprayed can be charged. The upper end of the outer container of the aerosol spray can be sealed with a valve, and when the valve is opened and used, the drain pipe cleaning agent composition in the inner container can be continuously sprayed over a predetermined time.

[0017] In the present invention, the chlorine-based cleaning agent component may include hypochlorite, which has excellent bactericidal and bleaching effects. When diluted, it has a high decomposition rate, low residue, and low oral toxicity. Therefore, it can be effectively used for cleaning, sterilizing, and disinfecting sink garbage receivers, drain outlets, and drain pipes. More specifically, the hypochlorite may include any one or more selected from the group consisting of sodium hypochlorite, potassium hypochlorite, calcium hypochlorite, magnesium hypochlorite, etc., but is not limited thereto. Desirably, sodium hypochlorite can be used as the chlorine-based cleaning agent component.

[0018] The chlorine-based cleaning agent component, desirably hypochlorite, can be used in an amount of 0.1 to 30% by weight, desirably 5 to 27% by weight, more desirably 15 to 25% by weight based on the total weight of the composition. If the chlorine-based cleaning agent component, desirably hypochlorite, is used in an amount of less than 0.1% by weight, the function as a bactericide or disinfectant becomes weak, and if it is used in an amount exceeding 30% by weight, the compatibility with the surfactant is poor, and it is also disadvantageous in terms of the stability of hypochlorite ions themselves.

[0019] In the present invention, the detergent composition may contain an anionic surfactant, a nonionic surfactant, or a mixture thereof to increase the bactericidal or disinfecting power of hypochlorite ions and improve the cleaning effect and viscosity. Desirably, the anionic surfactant may contain an alkyl ether sulfate of the following Chemical Formula 1, desirably SLES (sodium lauryl ether sulfate).

[0020]

Chem.

[0021] Desirably, the anionic surfactant may contain a mixture of the alkyl ether sulfate of Chemical Formula 1 and an alkylamine oxide of the following Chemical Formula 2. Desirably, lauramine oxide may be used as the alkylamine oxide of Chemical Formula 2.

[0022]

Chem.

[0023] In the present invention, by using a mixture of the alkyl ether sulfate and the alkylamine oxide as the anionic surfactant, a synergistic effect between the surfactants and an interaction between the surfactant and the hypochlorite can form excellent detergency and viscosity as compared with the case where each is used alone.

[0024] Desirably, the weight ratio of the alkyl ether sulfate to the alkylamine oxide may be 1:20 to 20:1, desirably 1:10 to 10:1, more desirably 1:1 to 10:1 (alkyl ether sulfate: alkylamine oxide). When the alkyl ether sulfate and the alkylamine oxide are used within the weight ratio range, the viscosity of the detergent composition of the present invention is most excellently formed.

[0025] In the present invention, the anionic surfactant, nonionic surfactant, or a mixture thereof may be contained in an amount of 1 to 40% by weight, preferably 3 to 30% by weight, more preferably 5 to 20% by weight based on the total weight of the detergent. When the content of the surfactant is less than 1% by weight, the cleaning performance is slight, and when it exceeds 40% by weight, there is a problem that the solubility of the detergent decreases.

[0026] The detergent composition of the present invention may further contain any components within a range that does not harm the object of the present invention, and in order to maintain the basic physical properties and quality as a detergent composition, preservatives, thickeners and viscosity modifiers, fragrances or dyes, etc. that are useful and commonly used in detergent compositions may be further contained. In the present invention, the drain pipe detergent composition may further contain a fragrance in order to reduce the strong odor of hypochlorite ions during use and to meet aesthetic requirements. As the fragrance, one that is stable to hypochlorite ions may be used, and it may be used in an amount of 0.01 to 2% by weight based on the total weight of the detergent composition.

[0027] Also, as the preservative, for example, methyl paraben, a mixture of methylchloroisothiazolinone and methylisothiazolinone (trade name: Kathon CG, manufacturer: Rohm and Haas, USA), etc. may be used. As the thickener and viscosity modifier, hydroxypropylmethylcellulose, hydroxymethylcellulose, sodium chloride, ammonium chloride, propylene glycol, or hexylene glycol, etc. may be used. As the dye, water-soluble tar dyes, etc. may be used.

[0028] In the present invention, the drain pipe detergent composition may further contain a thickener in order to slow down the flowing-down speed. The viscosity of the detergent composition containing the thickener may be 100 to 10,000 cps. The thickener may be used, for example, one or more selected from the group consisting of acrylate polymers, xanthan gum, locust bean gum, carrageenan, pectin, and gelatin, etc., but is not limited thereto.

[0029] The drain pipe cleaning agent composition usable for the aerosol spray for drain pipe cleaning of the present invention may substantially contain no foaming agent. Desirably, the drain pipe cleaning agent composition may contain less than 5% by weight, more desirably less than 1% by weight, still more desirably less than 0.1% by weight, and most desirably may not contain any foaming agent based on the total weight of the composition. The aerosol spray for drain pipe cleaning of the present invention prevents the neutralization of the chlorine-based cleaning agent composition by substantially containing no foaming agent, and thus the cleaning power does not decrease.

[0030] In addition, the aerosol spray for drain pipe cleaning of the present invention exhibits a sufficient foaming effect only by spraying, omits the unnecessary foaming process by the foaming agent, and can minimize the loss of the cleaning components.

[0031] In the present invention, as the aerosol spray for drain pipe cleaning, a container that ejects the drain pipe cleaning agent composition contained inside the container in the form of an aerosol or foam from the ejection port at a specific pressure when opened can be used. Desirably, the aerosol spray for drain pipe cleaning of the present invention can be manufactured so that the drain pipe cleaning agent composition inside the container is continuously sprayed over a certain period of time until it is completely consumed when opened.

[0032] The aerosol spray of the present invention can be manufactured such that the compression force of the container is 3 to 9 bar, desirably 4 to 7 bar. When the compression force of the aerosol spray container is less than 3 bar, the ejection force of the cleaning agent composition is insufficient and the cleaning power becomes weak. When it exceeds 9 bar, there is a problem that the cleaning agent composition is rapidly ejected and the cleaning duration is reduced.

[0033] Desirably, the ejection port of the container of the aerosol spray of the present invention can be connected to the inlet of the drain port. When using an aerosol spray in such a form, the foaming cleaning agent composition ejected from the spray does not overflow from the drain port and the drain pipe and stays for a long time, and the drain port and the drain pipe can be effectively cleaned over a predetermined period of time.

[0034] Regarding the aforementioned predetermined time, the aerosol spray of the present invention can adjust the discharge amount and discharge time of the foaming detergent composition by adjusting the valve and injection port of the container. The discharge time of the aerosol spray of the present invention can be adjusted so that the detergent composition is discharged for about 1 to 10 minutes, preferably 1.5 to 8 minutes, more preferably 2 to 5 minutes. When the discharge time is less than 1 minute, the foamed detergent composition may be insufficient to fill the drain outlet and drain pipe. When it exceeds 10 minutes, the detergent composition may be discharged in an excessive amount wastefully.

[0035] To sufficiently exhibit the cleaning effect, the discharged foamed detergent composition can be left in the drain outlet and drain pipe for 10 minutes to 180 minutes, preferably 20 minutes to 150 minutes, more preferably 30 minutes to 120 minutes. When the standing time of the detergent composition of the spray is less than 10 minutes, the detergent composition cannot stay for a long time, and the cleaning effect becomes weak. When it exceeds 180 minutes, problems such as the generation of chlorine gas or the corrosion of the sink due to a wasteful increase in the cleaning time may occur.

[0036] The present invention also provides a method for cleaning a drain outlet and a drain pipe using the aerosol spray for cleaning the drain pipe.

[0037] Preferably, the cleaning method of the present invention can combine the aerosol spray for cleaning the drain pipe with the inlet of the drain outlet so that the cleaning agent is discharged during a predetermined time (Figure 10). In the aforementioned cleaning method, the predetermined time is applicable in the same manner as the content regarding the aerosol spray of the present invention. When such a method is used, denser bubbles can be generated than the method of pouring the first agent and the second agent and foaming them. When the detergent composition in the spray is sprayed, the foamed detergent is pushed in by high pressure so as to sufficiently fill the drain pipe. As a result, the cleaning method according to the present invention can maximize the cleaning effect of the drain outlet and the drain pipe by preventing the detergent composition from overflowing from the drain outlet and the drain pipe and allowing it to stay for a long time.

[0038] Further, in order to achieve the above object, the present invention provides a method for cleaning a sink drain pipe, comprising: (a) preparing a cleaning container including a first accommodating portion and a second accommodating portion for accommodating a first agent and a second agent respectively; (b) mixing the first agent and the second agent with each other; and (c) disposing the cleaning container at the inlet of the sink drain pipe and injecting the mixed foaming cleaning agent discharged from the discharge port of the cleaning container into the drain pipe.

[0039] In step (a), a cleaning container is prepared in which a first accommodating portion and a second accommodating portion for accommodating the first agent and the second agent separately are combined. In step (b), a physical force is applied to damage the separating portion between the first accommodating portion and the second accommodating portion so that the first agent and the second agent can be mixed with each other.

[0040] In step (b), the first agent and the second agent can be mixed with each other by rupturing the separating portion by a physical force such as a screw connection or a pressing operation. In step (a), the first accommodating portion and the second accommodating portion are separated from each other. In step (b), the first accommodating portion and the second accommodating portion are combined, and the first agent and the second agent can be mixed with each other.

[0041] Either one of the first agent and the second agent may be in powder form and the other may be in liquid form. In step (c), the cleaning container may be disposed in an inverted state to inject the mixed foaming cleaning agent into the drain pipe.

[0042] According to another aspect of the present invention, there is provided a cleaning container for cleaning a drain pipe, comprising: a first accommodating portion and a second accommodating portion for accommodating a first agent and a second agent respectively; and a rupturing portion provided in either one of the first accommodating portion and the second accommodating portion, wherein when a physical force is applied to couple the first accommodating portion and the second accommodating portion to each other, at least the other one is ruptured so that the first agent and the second agent are mixed with each other. The combined body of the first accommodating portion and the second accommodating portion is disposed at the inlet of the sink drain pipe, and a mixed foaming cleaning agent formed by mixing the first agent and the second agent is injected into the drain pipe.

[0043] In one embodiment, a cleaning container for cleaning a drain pipe including a first accommodating portion and a second accommodating portion of the present invention and a method for cleaning a drain pipe using the same can be used by mixing the first agent and the second agent and then spraying the mixture using an aerosol spray for cleaning a drain pipe of the present invention during use.

Advantages of the Invention

[0044] The aerosol spray for cleaning a drain pipe of the present invention sprays a composition for cleaning a drain pipe in the form of an aerosol or foam onto a sink waste receptacle, a drain opening, and a drain pipe, and the cleaning effect can be maximized by allowing the foamed cleaning agent to stay for a long time.

[0045] Further, according to the present invention, since the first agent and the second agent can be conveniently mixed and foamed using the coupling structure between the first accommodating portion and the second accommodating portion, there is an advantage that handling and use are convenient.

[0046] Also, since the mixed and foamed cleaning agent is gradually discharged from the cleaning container standing upright, the foam stays in the sink drain pipe for a long time, and the duration of the cleaning effect can be increased.

Mode for Carrying Out the Invention

[0048] Hereinafter, the present invention will be described with specific examples. However, the examples according to the present invention can be deformed into many other forms, and the scope of the present invention should not be construed as being limited to the examples described later. The examples of the present invention are provided to more fully explain the present invention to those having average knowledge in the industry.

[0049] Example: Production of a drain pipe cleaning agent composition used in an aerosol spray The raw material components were mixed at the ratio of the composition shown in Table 1 below to produce a drain pipe cleaning agent composition used in an aerosol spray.

[0050]

Table 1

[0051] The said drain pipe cleaning agent composition was filled in a container together with a compressed gas at a pressure of 5 bar to produce an aerosol spray. In the following experimental examples, the comparative examples have the same components as the examples, but were used as a liquid composition instead of an aerosol dosage form.

[0052] Experimental Example: Evaluation of Bactericidal Power and Cleaning Power of Drain Outlet Ten households were visited, and the sink drain outlet was cleaned using the aerosol spray for cleaning drain pipes of the present invention. Specifically, the aerosol spray can of the present invention was stood upside down and connected to the drain outlet, and the cleaning agent composition was sprayed for about 2 to 5 minutes and then left for about 1.5 hours for the cleaning effect. After the cleaning treatment, the number of microorganisms present in the trash can and the drain outlet was evaluated. The number of microorganisms was measured at a location 15 cm below the drain outlet from the inlet of the drain pipe.

[0053] The aerosol formulation example exhibited excellent bactericidal power of 99.9% or more for both the trash can and the drain pipe by discharging in a foamy and slow manner. On the other hand, the comparative example of the liquid formulation did not stay long in the trash can and the drain pipe and flowed down immediately, resulting in insufficient bactericidal power.

[0054] [Table 2]

[0055] FIG. 1 is an assembled cross-sectional view showing the configuration of a cleaning container for performing the cleaning method of a sink drain pipe according to a preferred embodiment of the present invention.

[0056] Referring to FIG. 1, the cleaning container provided by a preferred embodiment of the present invention includes a container body 100 in which a first accommodating portion 101 and a second accommodating portion 102 are interconnected, a partition portion 103 located between the first accommodating portion 101 and the second accommodating portion 102, a cap 105 screwed to the upper part of the container body 100 to cover the opening, and a rupturing portion 104 for rupturing the partition portion 103 by the physical force of the screw connection of the cap 105.

[0057] The container body 100 is integrally formed by interconnecting a first accommodating portion 101 and a second accommodating portion 102 that respectively accommodate a first agent 10 and a second agent 20. The shape of the container body 100 is not limited to the illustrated example and can be variously deformed.

[0058] The first accommodating portion 101 that houses the first agent 10 is located relatively closer to the upper end of the container body 100 than the second accommodating portion 102 that houses the second agent 20. It is desirable that the first accommodating portion 101 be inserted and fixed inside the second accommodating portion 102. In such an arrangement structure, the first agent 10 may be in powder form and the second agent 20 may be in liquid form, but it is not limited to such an example. That is, the first agent 10 and the second agent 20 can be provided in various forms selected from liquid, powder, tablets, etc. The first agent 10 and the second agent 20 form a foaming cleaning agent that can clean and sterilize the sink drain pipe when mixed with each other. As the compositions of the first agent 10 and the second agent 20, ordinary products can be adopted, so detailed descriptions thereof are omitted.

[0059] On the side of a location near the upper end of the second accommodating portion 102 (desirably, the portion where the screw is formed), a discharge port 102a in the form of a through hole for discharging the foaming cleaning agent is formed. This discharge port 102a is exposed when the cap 105 is opened from the second accommodating portion 102 and rises by a predetermined distance, and communicates with a gap 106 through which the mixed foaming cleaning agent is discharged.

[0060] The isolation portion 103 is located between the first accommodating portion 101 and the second accommodating portion 102 and isolates the first agent 10 and the second agent 20 from each other. The isolation portion 103 can be a member (for example, a thin film) different from the first accommodating portion 101 and the second accommodating portion 102, or can be provided by the bottom of the first accommodating portion 101.

[0061] The rupture portion 104 is interlocked by integrating with a cap 105 having a predetermined shape. As shown in FIG. 2, due to the physical force caused by the cap 105 being screwed to the container body 100 and moving downward, the rupture portion 104 rotates and ruptures the isolation portion 103, whereby the first agent 10 and the second agent 20 are mixed with each other. The end of the rupture portion 104 is substantially pointed or configured in a sharp shape so as to be able to rupture the isolation portion 103. The rupture portion 104 desirably has a cylindrical shape so as to rupture the isolation portion 103 over as large an area as possible, and one side is formed relatively long to form a sharp structure. Or, the rupture portion 104 may have a rod shape with a sharp end.

[0062] As shown in FIG. 3, when the cap 105 is retracted in the reverse direction by a predetermined distance, a gap 106 communicating with the outside may be formed between the cap 105 and the second accommodating portion 102. As a result, the mixed foaming detergent formed by mixing the first agent 10 and the second agent 20 can be gradually discharged to the outside of the container body 100 through the gap 106.

[0063] In the cleaning container having the above-described configuration, when the user intentionally turns the cap 105 in the closing direction, the rupture portion 104 advances to rupture the isolation portion 103, thereby releasing the isolated state between the first agent 10 and the second agent 20. When the isolation portion 103 ruptures, the powdery first agent 10 present in the first accommodating portion 101 and the liquid second agent 20 present in the second accommodating portion 102 are mixed with each other to form a foaming detergent.

[0064] After the foaming detergent is produced by mixing the first agent 10 and the second agent 20, when the cap 105 is turned in the opening direction, the mixed foaming detergent is switched to a state where it can be discharged to the outside from the discharge port 102a and the gap 106 between the container body 100 and the cap 105 communicating therewith.

[0065] In a state where the external discharge of the mixed foaming detergent is possible, as shown in FIG. 4, when the cleaning container is placed upside down at the inlet 200 of the sink drain pipe, the mixed foaming detergent is gradually injected from the inflow hole 201 of the drain pipe over a long time, and cleaning and sterilization treatments can be performed.

[0066] FIG. 5 is an exploded perspective view showing the configuration of a cleaning container for cleaning a sink drain pipe provided according to another embodiment of the present invention, and FIG. 6 is a combined cross-sectional view of FIG. 5.

[0067] Referring to FIGS. 5 and 6, a cleaning container provided by another embodiment of the present invention includes a container body 100' in which a first accommodating portion 101' and a second accommodating portion 102' are interconnected, a separating portion 103' located between the first accommodating portion 101' and the second accommodating portion 102', a cap 105' screwed to the upper part of the container body 100' to cover the opening, and a rupturing portion 104' that ruptures the separating portion 103' by physical force by a user's push operation.

[0068] The first accommodating portion 101' is located relatively closer to the upper end of the container body 100' than the second accommodating portion 102'. For this reason, it is desirable that the first accommodating portion 101' be inserted into the upper part of the second accommodating portion 102' by screw connection. It is desirable that a discharge port 101'a in the form of a through hole for discharging the mixed foaming cleaning agent be formed on the side portion of the first accommodating portion 101'. This discharge port 101'a communicates with the outside when the first accommodating portion 101' is rotated from the second accommodating portion 102' and rises by a predetermined distance.

[0069] The first agent 10 accommodated in the first accommodating portion 101' is preferably in powder form, and the second agent 20 accommodated in the second accommodating portion 102' is preferably in liquid form, but is not limited to such an example. That is, the first agent 10 and the second agent 20 can be provided in various forms selected from liquid, powder, tablets, etc. The first agent 10 and the second agent 20 form a foaming cleaning agent that can clean and sterilize the sink drain pipe when mixed with each other. As the compositions of the first agent 10 and the second agent 20, ordinary products can be adopted, and thus detailed descriptions thereof are omitted.

[0070] The separating portion 103' is located between the first accommodating portion 101' and the second accommodating portion 102' and separates the first agent 10 and the second agent 20 from each other. The separating portion 103' can be a member (for example, a thin film) different from the first accommodating portion 101 and the second accommodating portion 102, or can be provided by the bottom of the first accommodating portion 101'.

[0071] The rupture part 104' is separated from the cap 105' and is joined so as to be somewhat tightly sandwiched in the first accommodation part 101'. As shown in FIG. 7, when an external force is applied to the upper end of the rupture part 104' with the cap 105' removed, the rupture part 104' slides downward in the first accommodation part 101' and advances. Due to the physical force caused thereby, the rupture part 104' ruptures the isolation part 103', and the first agent 10 and the second agent 20 are mixed with each other when the isolated state is released. The end of the rupture part 104' is substantially pointed or configured in a sharp shape so as to rupture the isolation part 103'. The rupture part 104' is formed in a cylindrical shape so as to rupture the isolation part 103' over as wide an area as possible, and it is desirable that one side be formed relatively long to form a sharp structure. Alternatively, the rupture part 104' may be in the shape of a rod with a sharp end.

[0072] As shown in FIG. 8, when the screw of the first accommodation part 101' is loosened and the first accommodation part 101' is withdrawn from the second accommodation part 102' by a predetermined distance, the discharge port 101'a is exposed to the outside. As a result, the container body 100' communicates with the outside. Accordingly, the mixed foaming cleaning agent formed by mixing the first agent 10 and the second agent 20 is gradually discharged from the discharge port 101'a to the outside of the container body 100'.

[0073] In the cleaning container having the above-described configuration, when the user performs a pressing operation on the upper end of the rupture part 104' with the cap 105' removed to advance the rupture part 104' and rupture the isolation part 103', the isolated state between the first agent 10 and the second agent 20 is released. When the isolation part 103' ruptures, the powdery first agent 10 present in the first accommodation part 101' and the liquid second agent 20 present in the second accommodation part 102 are mixed with each other to form a foaming cleaning agent.

[0074] After the foaming cleaning agent is produced by mixing the first agent 10 and the second agent 20, by turning the first accommodation part 101' in the opening direction to slightly expose the discharge port 102'a to the outside, the mixed foaming cleaning agent is switched to a state where it can come out of the container body 100' and be discharged to the outside.

[0075] When the external discharge of the mixed foaming detergent is possible and the cleaning container is placed upside down at the inlet 200 of the sink drain pipe as shown in Fig. 9, the mixed foaming detergent is gradually injected from the inflow hole 201 of the drain pipe over a long period of time, and cleaning and sterilization treatment can be performed.

[0076] Fig. 10 shows the coupling structure of the cleaning container for performing the cleaning method of the sink drain pipe according to still another embodiment of the present invention.

[0077] In Fig. 10(a), the first accommodating portion 110 and the second accommodating portion 120 each accommodate the first agent and the second agent in isolation in the same manner as in the foregoing embodiment, and are provided in a mutually separated state.

[0078] In use, when the second accommodating portion 120 is coupled to the first accommodating portion 110 and the fastening is completed as shown in Fig. 10(b), the isolation portion 111 of the first accommodating portion 110 is ruptured by the rupture portion 125 provided in the second accommodating portion 120, and the first accommodating portion 110 and the second accommodating portion 120 communicate with each other, so that the first agent and the second agent are mixed with each other to form a foaming detergent. At this time, the isolation portion 111 of the first accommodating portion 110 is ruptured when the rupture portion 125 of the second accommodating portion 120 is inserted into the first accommodating portion 110 by a physical force by screw coupling or pushing operation. Alternatively, a predetermined isolation portion (isolation film) is provided at the end of the second accommodating portion 120, and it is also possible to mix with the first agent accommodated in the first accommodating portion 110 by being ruptured by being damaged during the insertion process and discharging the second agent accommodated therein.

[0079] When the cleaning container is placed at the inlet 200 of the sink drain pipe in a state where the first accommodating portion 110 and the second accommodating portion 120 are coupled, the mixed foaming detergent is gradually discharged through the gap between the first accommodating portion 110 and the second accommodating portion 120 over a long period of time and is injected through the inflow hole 201 of the drain pipe, and cleaning and sterilization treatment are performed.

[0080] As described above, the present invention has been explained by way of limited embodiments and drawings. However, the present invention is not limited thereto, and it goes without saying that various modifications and variations can be made by those with ordinary knowledge in the technical field to which the present invention pertains within the equivalent scope of the technical idea and claims of the present invention.
