Description

  The present invention relates to a disinfecting mat used to prevent the spread of viruses, bacteria, and fungi inside and outside each facility when entering or leaving a facility such as a livestock facility, a residential facility, or a public facility.

  Viruses such as foot-and-mouth disease virus, influenza virus, avian influenza virus, O-157 virus, norovirus, rotavirus, and other bacteria that cause disease in humans and animals, bacteria such as Staphylococcus aureus, Pseudomonas aeruginosa and pathogenic Escherichia coli, mold toxin The fungi that generate water are not only scattered in the air but also accumulated on the ground, and when pathogens enter or leave livestock facilities, residential facilities, public facilities, etc. The risk of spreading over a wide range and infecting humans and animals and increasing the disease level is increased.

  For this reason, foot-wiping mats, etc., coated with chemicals that sterilize and disinfect these pathogens are installed at the entrances and exits of each facility to prevent the spread of the viruses, bacteria, fungi, etc. attached to the back or side of footwear. Has been.

  Such a foot-wiping mat is a general-purpose rubber foot-wiping mat used to remove soil and sand on the back of footwear, and a medicine for sterilizing pathogens such as viruses, bacteria, and fungi is applied. It is commercially available.

  Patent Document 1 discloses a sterilization mat manufactured through an alkaline compound impregnation step in which an aqueous solution of an alkaline compound is supplied to a mat body such as a nonwoven fabric and then dried.

  Moreover, in patent document 2, it consists of the base which accommodated the mat main body and the mat main body, and the mat main body is comprised by the sponge structure, The disinfection liquid, the cleaning liquid, the alkaline liquid, the acidic liquid, the deodorizing liquid, Chemical liquid mats impregnated with chemical liquids such as mold liquid have been released.

  Since the above-mentioned commercially available foot wipe mat is made of rubber, it is heavy, and it is difficult to carry a plurality of sheets when storing and transporting when not in use. Also, because it is made of rubber, the disinfectant does not penetrate into the foot cleaning mat itself, the chemical solution evaporates in a short time, and it is necessary to replenish the chemical solution frequently. There is a risk of causing it. In addition, when incinerated and discarded, if the mat material is vinyl chloride or if a chlorinated compound is mixed as a plasticizer for rubber, dioxins that are toxic to the human body may be generated. Absent.

  In addition, in the invention described in Patent Document 1, it seems that the problem of the rubber foot wipe mat described above is overcome, but an alkaline compound is once dissolved in water, and the mat body is impregnated with the aqueous solution. After that, it is manufactured through the process of evaporating water, so it requires heat energy to evaporate water, and it takes time to evaporate water, which affects the productivity of products. From the viewpoint of manufacturing a product at a low cost, it was not sufficient.

  In addition, in the invention described in Patent Document 1, an alkaline compound is used as a material that exhibits a bactericidal effect, and even if the aqueous solution has a bactericidal power, mats such as sandals are exposed to the skin. When the body is stepped on, the aqueous solution may splash up and adhere to a part of the skin. However, in that case, the irritation caused by the alkaline aqueous solution is not particularly felt, and there is a risk of a chemical injury that a part of the skin to which the alkaline aqueous solution adheres unintentionally dissolves.

  Furthermore, in the invention described in Patent Document 1, since salts are used as the alkaline compound, even if the mat can be incinerated and discarded, the alkaline salts remain in the incinerator after incineration. However, even if a small amount of alkaline salt is impregnated in the mat, salt is accumulated in the incinerator every time the mat is incinerated, so the alkaline salt erodes the inner surface of the incinerator and the incinerator This is not preferable because it shortens the life of the product.

  Further, in the invention described in Patent Document 2, the mat main body is impregnated with a liquid chemical solution, and the impregnated mat main body is held on the pedestal. In this case, it is necessary to take care not to leak the chemical solution, or it is necessary to impregnate the mat main body with the chemical solution for the first time at the time of use.

  Therefore, in the present invention, in order to solve the above-mentioned problems, the production cost is reduced by generating no harmful substances to the human body at the time of incineration, simplifying the production process, suppressing energy consumption at the time of production, and increasing the productivity of the product. Even if the chemical solution adheres to a part of the skin, there is no risk of causing a chemical burn on the part of the skin without knowing it, and it does not shorten the life of the incinerator when discarded by incineration. The purpose is to facilitate the storage management of

  That is, the sterilizing mat according to the present invention is a disinfecting mat characterized by holding a solid organic acid on a sheet having a three-dimensional network structure at 5 ° C.

  If it is such, there exist the following effects.

  In other words, since a sheet having a three-dimensional network structure is used, the entire foot mat becomes light and easy to carry.

  In addition, since a solid organic acid is used at 5 ° C. as a chemical exhibiting a sterilizing / disinfecting effect, the step of dissolving the chemical in water and impregnating the mat can be omitted to improve productivity. Since there is no need for a process for evaporating the heat, it is not necessary to add heat energy, and energy consumption during production can be suppressed.

  In addition, since a solid organic acid is used at 5 ° C. as a drug that exhibits a sterilizing / disinfecting effect, the aqueous solution of the solid organic acid is used in a wet state by supplying moisture to the stepping disinfection mat. Even if it adheres to a part of it, it is highly safe and does not affect the human body, and since it feels some irritation to the attached part, it is possible to prevent chemical injury by wiping the medicine or washing it with water.

  And since a solid organic acid is used at 5 ° C. as a drug that exhibits a bactericidal effect, not only when the step disinfection mat is incinerated, but also the solid organic acid is composed of an organic compound. When the foot sterilization mat is completely burned, all of it is decomposed into water and carbon dioxide and no salt remains, so the incinerator is not damaged and the life of the incinerator is not shortened.

  In addition, since a solid organic acid is used at 5 ° C. as a chemical exhibiting a bactericidal effect, there is no leakage of chemicals, and there is no need to pay particular attention during storage management when not in use.

  In order to simplify the production and energy saving of the foot disinfecting mat of the present invention and facilitate storage management when not in use, the solid organic acid is sandwiched between at least two sheets of the three-dimensional network structure. It is desirable to have a mat body.

  In order to prevent the aqueous solution from flowing out of the mat when it is used in a wet state by supplying moisture to the foot sterilization mat, in order to prevent the sterilization / disinfection effect from being reduced, at least the sheet of the three-dimensional network structure or the mat body It is desirable to cover the side and bottom surfaces with a hydrophobic film.

  In order to reduce evaporation of moisture contained in the mat body when supplying moisture to the mat body of the foot sanitizing mat and using it in a wet state, at least two layers of the three-dimensional mesh structure sheet of the mat body It is desirable to hold the water-absorbing resin between the sheets or the sheet having the three-dimensional network structure.

  In order to remove oil stains adhering to the back of the footwear and increase the sterilizing / disinfecting effect when supplying moisture to the foot sanitizing mat and using it in a wet state, it is between the at least two layers of the mat body or the three-dimensional mesh. It is desirable to retain the surfactant in the structured sheet.

  As described above, according to the foot disinfecting mat according to the present invention, no chlorine-based compound is used, and therefore no harmful substances such as dioxin are generated in the human body when incinerated after using the foot disinfecting mat.

  And since the mat main body which is the laminate body of the said three-dimensional network structure which hold | maintained the said organic acid in the stepping disinfection mat, or those and the said solid organic acid is used, it becomes lightweight as a whole stepping mat. Easy to carry.

  Further, since a solid organic acid is used at 5 ° C. as a drug that exhibits a bactericidal effect, the process of dissolving the drug in water and impregnating the sheet of the three-dimensional network structure or its laminate is omitted. Energy consumption can be suppressed since a process for evaporating water is not necessary.

  Since a solid organic acid is used at 5 ° C. as a drug that exhibits a bactericidal effect, even if an aqueous solution of the organic acid adheres to a part of the skin at the time of use, the safety is high and the human body is not affected. In addition, since some irritation is felt in the attached part, the chemical injury can be prevented by wiping the drug or washing with water.

  In addition, since a solid organic acid is used at 5 ° C. as a chemical that exhibits a bactericidal effect, not only the sheet having the three-dimensional network structure but also an organic acid is composed of an organic compound when the stepping disinfection mat of the present invention is incinerated. As a result, when the stepping disinfection mat is completely burned, all of it is decomposed into water and carbon dioxide, so no salt is produced and the incinerator is not damaged and the life of the incinerator is not shortened.

  And since a solid organic acid is used at 5 ° C. as a drug that exhibits a bactericidal effect, when the foot sterilization mat of the present invention is manufactured and stored or transported when not used, the sheet having the three-dimensional network structure is used. The organic acid does not leak from the gap.
