Description

The present invention is provided at a place where slime or bad smell is generated due to metabolites such as germs and mold, such as a drain of a kitchen sink, a drain of a bathroom, a drain of a toilet floor, etc., to remove slime. , A slime-removing device useful for preventing the occurrence of slime or controlling slime, a container therefor, and a method for removing slime using the same, and in particular, a drain port of a kitchen sink for home use. A large-sized, garbage-removing basket is set up, and garbage, such as food scraps that have flowed out together with the wastewater, is collected by the garbage-removing basket. About the vessel.

It is known that the main components of slime in kitchen sinks and bathroom drains are polysaccharides that are secreted by bacteria at the time when food, surfactants, soap, human scum, etc. serve as nutrients for bacteria. I have.

Conventionally, a chlorine-based oxidizing agent such as trichloroisocyanuric acid, dichloroisocyanurate, or bromochlorodimethylhydantoin is used alone or in combination with other components as an agent for preventing slime in a garbage basket at the drain of a household sink. Tablets obtained by pressing and molding the tablets are housed in a plastic net or basket-shaped container, and are suspended in a basket for removing dust with a string or the like. These have been sold for several years and have been put to practical use under the name of "slimming agent".

The above chemicals are effective in preventing slime and bad smell of garbage cans due to the strong sterilizing power of chlorine-based oxidizing agents, and are widely used. Due to their strong oxidizing power, the garbage cans and surrounding drain outlets are used. In addition to deteriorating and corroding the material, there is a problem in safety such as generation of irritating odor gas such as chlorine gas or nitrogen trichloride generated by the reaction of chlorine gas with nitrogen in food waste.

種 々 In order to solve the above problems, various "slimming agents" using a bactericide other than a chlorine-based oxidizing agent have been proposed. For example, peroxides such as sodium percarbonate, potassium persulfate, and sodium perborate (see Patent Documents 2 and 3), iodine-based fungicides such as povidone iodine (see Patent Documents 4 and 5), and sulfur compounds such as sulfites And an antibacterial agent (see Patent Document 6), volatile disinfectants such as orthophenylphenol, diphenyl, 2-isopropyl-5-methylphenol, and hinokitiol (see Patent Document 7), silver ion, copper An inorganic disinfectant in which ions or the like are supported on an inorganic compound such as zeolite or silica gel (see Patent Literatures 8, 9, and 10), or an industrial disinfectant such as parachlorometa-xylenol or the like alone or with an appropriate dissolution regulator added Press molded tablets are known.

The "slimming agent" using a bactericide other than these chlorine-based oxidizing agents, like the "slimming agent" made of a chlorine-based oxidizing agent, is stored in a plastic net or basket-like container, and is garbage-treated with a string or the like. It is suspended in the take-out basket and is partially marketed as a `` slimming agent '' that does not use a chlorine-based oxidizing agent. The bactericidal power is weak, the effect of preventing slime and odor is inadequate, and it is not widely used.

JP-A-7-184823 (Patent Document 11) discloses an antibacterial agent such as a mixture of 5-chloro-2-methyl-4-isothiazolin-3-one and 2-methyl-4-isothiazolin-3-one. Is carried in a water-permeable bag such as a non-woven fabric, or is supported on a water-soluble substance such as a protein or polysaccharide, and is formed into a film-like "numery removing agent". Is described. However, 5-chloro-2-methyl-4-isothiazolin-3-one has a strong antibacterial activity and does not cause material corrosion or gas generation, but is easily soluble in water and has a long shelf life. In addition to the short-term disadvantages, the skin is highly irritating, and thus poses a safety problem when used at home.

In addition to the above, a garbage basket having a mounting portion for attaching a container containing a slime-removing agent to a garbage basket handle via a connecting portion (see Patent Document 12) or a garbage net basket whose surface is coated with a fluororesin is used. One to be used (see Patent Document 13), one to spray electrolytic acidic ionic water from an annular pipe provided around a net basket (Patent Document 14), and a solution having a bactericidal and fungicidal action on the upper part of a drain port An antibacterial and antifungal device for supplying (Patent Document 15) and the like are known.

An object of the present invention is to provide a solution of a slime control agent from a container containing a slime control agent that can be easily installed at an upper portion of a drain port, is excellent in safety and handleability, and maintains appropriate solubility. An object of the present invention is to provide a drainage slimming device that can be spread on a drain pipe wall or the like.

The present inventors have proposed a non-bleachable powdery slime control agent obtained by press-molding an inclusion compound comprising 5-chloro-2-methyl-4-isothiazolin-3-one and a multimolecular host compound. (Japanese Patent Application No. 9-50384). Since this controlling agent uses 5-chloro-2-methyl-4-isothiazolin-3-one as a multimolecular clathrate with a host compound, skin irritation is reduced, and solubility in water is also reduced. It is an excellent slime control agent. The present inventors have also proposed a slime control agent obtained by press-molding an organic iodine antibacterial agent and a solid acid (Japanese Patent Application No. 9-50385), and this slime control agent is also excellent. Slime control effect has been confirmed.

By the way, if a chemical containing a chlorine-based oxidizing agent as an active ingredient, even if it is installed at the bottom of a garbage can, the generated chlorine gas can sterilize even the part that does not come into contact with the chemical solution, so that the entire slime inside the basket can be sterilized. While prevention is possible, a drug containing a non-chlorine-based oxidizing agent as an active ingredient, in particular, the above-mentioned 5-chloro-2-methyl-4-isothiazolin-3-one was converted into a multimolecular clathrate with a host compound. The excellent slime control effect of a slime control agent formed by pressing a slime control agent or an organic iodine antibacterial agent is limited to the peripheral part where the drug is installed, especially for the part above the position where the drug is installed. We found that the effect was weak. Therefore, these slime control agents can be installed at the entrance or upper part of the drainage pipe, and various types of slime removal containers for drainage ports capable of spreading the solution of the slime control agent on the drainage pipe wall surface and the like, The slime control effect was examined, and the slime control effect was confirmed. Thus, the present invention was completed.

About.

Furthermore, the present invention is a container having a shape that can be installed at the entrance or upper portion of the drainage port, and that can store therein a solid material containing a substance that suppresses the growth of microorganisms, and a bottom portion or a lower portion of the side portion. Or, in addition thereto, a solid solution outflow hole on the side surface, and a drainage inflow hole on the upper surface or the upper side surface, respectively, and the total opening area of the solution outflow hole is 0.98 of the total opening area of the drainage inflow hole. The present invention relates to a slime-removing container capable of spreading a solution of a solid material having a thickness of from 0.01 to a slime-generating wall portion.

The slime removing device for a drain port of the present invention can be easily installed on the upper portion of the drain port, is excellent in safety and handleability, and drains a solution of the slime controlling agent from a container containing the slime controlling agent. It can be spread on the wall, and the opening area of the inflow hole for drainage and the opening area of the outflow hole for discharging the solution are adjusted, so that the minimum required amount of drainage is taken into the container while the drainage is flowing Even after the drainage is finished, the solution in which the drug is dissolved flows out of the container. In the conventional basket-shaped container, most of the chemicals flowed out together with the drainage and remained at the slime generating portion and did not exhibit the effect of controlling the slime, whereas the slime removing device for the drainage port of the present invention is not diluted by the drainage. Because the solution contacts the slime-generating area for a long time, slime can be effectively prevented with a small amount of chemicals, and the amount of chemicals flowing out into the wastewater is very small. Little effect. In addition, since the active ingredient is eluted at an appropriate dissolution rate, it is provided at a place where slime is generated by metabolites such as germs and molds, such as a kitchen sink or a drain of a bathroom, and the slime is removed. Can be prevented for a long period of time.

May be. As the form of use of the solid material, for example, there is a case where a single cylindrical material or a donut shape is used according to the shape of the solid material storage portion of the container, but a large number of small particles can also be used. . When a large number of small particles are used, in addition to using the same type, a plurality of different small solids such as drugs having different blending components or drugs having different solubilities can be used. The solid substance in the present invention has a form capable of preventing the active ingredient from flowing out more than necessary when it comes into contact with the wastewater and can be dissolved in the wastewater contacted at an appropriate speed, for example, Numeri. Non-woven fabric, paper, film or other water-permeable bags or tubes containing a control agent, slime control agent or the like carried on a sponge, resin foam, or liquid slime control agent And the like are impregnated with a porous mineral or the like for convenience.

Next, in the present invention, the container for storing the solid matter containing the growth inhibitor of microorganisms has a shape that can be installed at the inlet or upper part of the drainage port, and has an opening degree that can control the inflow of drainage. Drainage inflow holes provided on the upper or upper side of the container and the bottom or side of the container having an opening degree that can control the amount of the solid solution flowing out, or the solution outflow provided on the side in addition thereto Any material may be used as long as it has pores and can spread the solid solution on the wall surface where the slime is generated. Examples of the shape that can be installed at the inlet or upper part of the drain port include a shape formed by a flange-shaped locking portion formed on the peripheral portion of the ring-shaped container main body, and a plurality of members extending horizontally from the container main body. In addition to the shape consisting of a stop piece, the shape consisting of a plurality of locking pieces standing upright from the container body, the lid shape such as a chrysanthemum-shaped rubber lid installed at the sink sink drain, and such a rubber lid A ring-shaped container or the like that can be fitted or attached to the upper or lower part of the housing by utilizing the elastic force of an elastic body such as rubber. Further, in addition to disposing a solution outflow hole at the lower side of the container body so that the solid solution can be spread on the slime-generating wall surface, a distribution pipe and a distribution gutter are provided at or near the solution outflow hole. , A thin rod-shaped distribution pin or the like may be provided.

  When the solid matter is stored in the container, it may be introduced into the container through a drainage inlet if it is a small one. A part having a solid material inlet and a lid can also be used. In addition, in order to enable the container to be installed at the entrance or upper part of the drain port, as described above, the one in which the locking member is integrally provided in the container body can be used. When a stopper or a lid is provided in the container, a container having a similar shape to the stopper or the lid can be preferably used. When the container is a lid provided at the drain of the sink, it can be simply and simply installed. As the material of these containers, various known materials such as plastic, rubber, and metal can be used, but various plastics are preferably used from the viewpoint of cost, processing, and the like. In particular, in the case of a container having a lid provided at the drain of the sink sink, a plastic lid, for example, a colored plastic lid may be used instead of the conventional rubber lid.

  The drainage inflow hole is provided on the upper surface or upper side of the container, and is arranged so as to have an opening degree that can control the amount of inflow of drainage, that is, when the amount of drainage is large, a part of the drainage is solidified through the drainage inflow hole. Although it flows into the goods storage part, most of it is arranged so as to be drained without passing through the drainage inflow hole, and specifically, one or a plurality of adjusted ones are provided on the upper surface or upper side surface of the container. The drainage inflow hole with an open degree is provided, and the drainage inflow hole is provided at the base of the adjusted water channel that only part of the drainage is led to the drainage inflow hole. it can. By providing such a drainage inflow hole, since the inflow amount is controlled, even when the drainage amount is large, it is possible to suppress the backflow of the solid solution from the drainage inflow hole.

  In addition, the solution outflow hole is provided at the bottom or lower side of the container or in addition to the side so that the solid solution can be spread on the slime-generating wall portion, and specifically, a drain port Dissolved liquid flows out to the inside of the lid, such as one with a plurality of dissolving liquid outflow holes with a controlled opening degree along the mouth of the garbage or the upper edge of the garbage basket, and the inside of the lid such as a chrysanthemum-shaped rubber lid A hole with a hole to allow the solution to diffuse on the front and back of the rubber lid, and a controlled opening at the base end of a plurality of distribution pipes (gutters) whose tip can contact the upper part of the drain pipe or the upper part of the garbage basket. A dispensing hole having a dissolving solution, or a distributing pin having a thin rod-like shape which can contact the upper part of a dust removal basket at a position close to the dissolving solution outflow hole instead of a distribution pipe (gutter) And the like.

Then, as a solution outflow hole having a controlled opening degree, the maximum amount of water that can be held in the container flows out in 0.5 to 500 seconds, preferably 2 to 100 seconds, more preferably 5 to 50 seconds. One having a total opening area can be given. If the maximum volume of water in the container is less than 0.5 seconds, and the solution has a total area of the opening, the solution drains out while the used wastewater does not end and a small amount of wastewater flows. Since the solution is diluted, the concentration of the drug that remains in the slime-generating area is reduced, and the effect of controlling the slime is weakened. Unnecessarily consumed. On the other hand, in the case of a solution outflow hole having a total opening area such that the outflow time exceeds 500 seconds, the area of the outflow hole becomes too small, and troubles such as clogging of the outflow hole by debris or chemical debris in drainage occur. More likely to occur. However, when the time is less than 2 seconds or more than 100 seconds, the tendency in the case of less than 0.5 seconds or more than 500 seconds becomes extremely small.

Further, when the total area of the opening of the solution outflow hole is set to 0.98 to 0.01, preferably 0.95 to 0.1 of the total area of the opening of the drainage inflow hole, the drainage can be performed even when the drainage amount is large. The amount of the solid solution flowing out during the flow of the wastewater is small, so that the effective concentration of the solution can be flown out after the drainage has finished flowing, and more efficient slime control can be achieved. If the total area of the opening of the solution outflow hole exceeds 0.98 of the total area of the opening of the drainage inflow hole, the amount of drainage flowing into the container becomes small when the drainage time is short, and the drug is sufficiently dissolved. In addition, it is difficult to secure a sufficient amount of the solution to spread on the wall surface, and the slime control effect becomes insufficient. On the other hand, if the total opening area of the solution outflow hole is less than 0.01 of the total opening area of the drainage inflow hole, the opening portion of the drainage inflow hole becomes too wide, and the drainage inflow speed is too fast, so that the solution This causes a problem that the active ingredient flows out of vain together with the wastewater, and garbage or the like flows into the container.

  Regarding the shape of the drainage inflow hole and the solution outflow hole, if the wastewater can flow in or the solution can flow out, any shape such as circular, oval, rectangular, star, slit, ring, etc. Although such a shape may be used, the shape of the drainage inflow hole is preferably a slit shape effective for preventing inflow of garbage and the like, a large number of small holes, a mesh shape, etc., in this case, the width of the slit, The area of the small holes is adjusted so that the inflow of dust is small and the inflow of drainage is not hindered by surface tension. In addition, as long as the drainage can be introduced, the opening can be covered with a water-permeable material such as a nonwoven fabric. In this case, the opening area of the drainage inflow hole is regarded as the opening area having the same water flow rate. be able to.

か ら Further, it is preferable that the shape of the hole of the solution outflow hole is a slit shape cut out from the bottom to the lower side of the container from the viewpoint of preventing clogging due to inflowing garbage and the like and of the advantages of the shape. By adopting such a shape, even if garbage etc. accumulates at the bottom, the solution outflow hole is not completely closed, and also the dissolution of the drug is prevented from being remarkably accelerated due to the constant accumulation of water in the container. it can.

In the present invention, the slime-generating wall portion means a kitchen sink, a bathroom, an inner wall portion of a drain pipe on the floor of a toilet, a front and back surface of a rubber lid of a sink sink drainage, and a garbage removal basket installed thereunder. Of the garbage container placed in the sink sink, such as a flat surface or a curved surface, on which slime occurs.

  Next, the slime removing device of the present invention, in particular, a rubber cover provided at a sink sink drainage port, and a slime removing device applied to a trash removing basket provided thereunder will be specifically described.
