Description

  The present invention relates to a mask, and more specifically, pollens, dust floating in the air, bacteria such as Mycobacterium tuberculosis, pathogenic bacteria such as viruses such as influenza virus and Thurs virus, formalin, thinner, ammonium, smell of tobacco, etc. Can effectively prevent inhalation of other odorous components and other pollutants and harmful substances, and has the effect of alleviating symptoms of patients with respiratory diseases such as asthma caused by moisture inhalation. The present invention relates to a mask effective for prevention of disease infection, and also for relief of symptoms in patients with respiratory diseases.

  In recent years, due to air pollution, organic solvents contained in building materials and paints, new viruses, pollen such as cedar and cypress, etc. The amount of pollutants is increasing. For this reason, sick house syndrome, influenza such as Thurs, hay fever, etc. are major social problems. Therefore, the necessity and importance of masks are increasing in order to prevent inhalation of the harmful substances and pollutants.

  At present, a wide variety of masks are commercially available. A general mask currently on the market is a gauze mask in which a covering portion that covers the mouth and nostril is made of gauze, and elastic ear-hook portions made of rubber strings or the like are provided on both sides thereof. Disposable masks made of non-woven fabric are also commercially available (see, for example, Patent Documents 1 to 3). Furthermore, there is a mask that improves the wearing feeling by devising the shape of the cover portion so that the cover portion does not adhere to the mouth and nostril (see Patent Documents 1 to 3, etc.). Furthermore, a mask having a double cover portion has also been proposed (see, for example, Patent Document 4). These masks remove harmful substances and pollutants such as dust, pathogens and pollen in the air when the inhalation when the wearer breathes passes through the gauze and nonwoven fabric constituting the cover. It is filtered with gauze or non-woven fabric to prevent inhalation from the nostril or mouth. For this reason, the conventional mask has been devised so that the gauze of the covering portion and the eyes of the non-woven fabric are made as small as possible so that the harmful substances in the air as described above do not pass through as much as possible.

  However, the various harmful substances and contaminants floating in the air are very fine. For example, in the case of pollen, the particle size of cedar pollen is 30 to 40 μm, ragweed pollen is 18 to 20 μm, cypress pollen is 0.5 μm to more, and grass pollen is 30 to 50 μm. The size is about 0.02 to 0.3 μm. In the case of influenza virus, the size is about 0.11 μm, and the tuberculosis bacteria is 0.3 to 0.6 μm wide and 1 to 4 μm long. Incense smoke contains fine particles of about 1 to 2 μm. Furthermore, malodorous components such as tobacco smoke are ultrafine particles of 0.2 μm or less. It is difficult to effectively prevent the inhalation of such fine harmful substances by making the mask gauze, non-woven fabric, etc. finer, and if possible, a highly functional material is necessary and the price of the mask Also gets higher. However, it is not only technically limited to make the gauze and non-woven eyes that cover the nostrils and mouth fine, but if the gauze and non-woven eyes are made too fine, the breathability is extremely reduced, making it difficult to breathe when worn. There is a problem.

  In addition to the purpose of preventing inhalation of substances in the air together with inhalation during breathing, the gauze constituting the covering part for the purpose of preventing colds, other diseases, hay fever, etc. There has also been proposed a mask in which water (humidity) and a medicine are contained in the body and the moisture and the medicine are inhaled together with inhalation. For example, a wet mask method has been proposed in which a cold or the like is prevented by wetting the gauze of the cover and humidifying the intake air (see Non-Patent Documents 1 and 2). In addition, a mask (see Patent Document 5) in which a container filled with a drug such as a dried medicinal plant is attached to the mask cover (see Patent Document 5), a gauze containing a drug, or a pocket made between the gauze A medicinal mask containing a medicine in the inside (see Patent Document 6), a volatile drug sustained-release mask in which a powder in which a volatile drug is included in cyclodextrin is attached to gauze of a cover (patent Reference 7). A menthol-containing mask provided with a menthol sustained-release holding body composed of a microporous hollow fiber containing menthol (see Patent Documents 8 and 9, etc.), impregnated with a propoly extract solution having an effect of improving hay fever Hygiene mask for hay fever used by wrapping cloth with gauze (refer to Patent Document 10), water-containing material soaked with water and medicines can be stored in a plastic bag with a lot of vents and put in and out of the cover part A method for eliminating discomfort in the nostrils caused by aroma, by spraying a moisture inhalation mask (see Patent Document 11), a fragrance solution such as mint essence, menthol, hinokitiol on the inside of the cover immediately before wearing to cover the nostrils ( (See Patent Document 12.), a volatile agent such as menthol and ethanol is impregnated into a hygroscopic sheet, and this is packaged with a wrapping material with a hole, and a mask equipped with this (patent 13)), volatile compounds such as ethanol, butyl alcohol, menthol and other monovalent alcohols, volatile sulfides, acids, basic compounds, trihalomethanes, etc. that physiologically malfunction the upper respiratory mucosal cells are masked A method for treating colds and hay fever by inhalation (see Patent Document 14) has also been proposed.

  As described above, all masks that contain moisture or chemicals in the cover of gauze etc., can evaporate the moisture or chemicals by breathing and inhale with inhalation to prevent sickness such as colds and hay fever. Since prevention or treatment is performed, the volatile component as described above is used as the chemical solution. Therefore, although these conventional masks can inhale moisture and chemicals, a sufficient effect cannot be expected in terms of preventing inhalation of such extremely fine harmful substances and pollutants floating in the air. . In addition, as described above, when the mask cover is directly impregnated with water or chemicals, or a cloth impregnated with chemicals is inserted, the cover becomes heavy and the mask slides off the face. In addition, the impregnated chemical liquid oozes out from the covering portion and wets around the wearer's mouth and nose, causing uncomfortable feeling.

  In view of the problems of the conventional mask as described above, the present invention inhales extremely fine harmful substances and pollutants such as pollen, dust, bacteria, viruses and other pathogenic bacteria floating in the air, and further malodorous components. The purpose of the present invention is to provide a mask that can effectively prevent the occurrence of cold, hay fever, etc., and can further exert an excellent deodorizing effect, and that does not cause discomfort to the wearer. To do.

Mask of the present invention includes a cover portion having at least the mouth and breathable created shape and dimensions capable of covering the nostrils, and ear shell which is provided on both sides of the cover portion, the cover part is, non-hygroscopic nonwoven fabric has superimposed on at least double, during the non-hygroscopic nonwoven fabric, the hygroscopic fabric or nonwoven fabric, 1,3-butanediol, 1, 4-butanediol, 1,5 at least one selected from the group consisting of pentane diol, and, the liquid-impregnated sheet impregnated with a liquid containing one or more nitrogen-containing type nonionic surface active agent It is characterized by being sandwiched.

  It is more preferable that the liquid impregnated in the liquid-impregnated sheet contains a compound having at least one action of deodorizing, sterilizing, antibacterial and antiviral, or a compound having a composite action thereof.

  The nitrogen-containing nonionic surfactant is preferably at least one selected from the group consisting of polyoxyethylene fatty acid amides, polyoxyethylene alkylamines, alkylamine oxides, and fatty acid alkanolamides. Preferably, the polyoxyethylene fatty acid amide and the polyoxyethylene alkylamine are at least one kind, and the polyoxyethylene fatty acid amide fatty acid amide or the polyoxyethylene alkylamine higher alkylamine has 12 carbon atoms. It is preferable that the number of moles of ethylene oxide added to the fatty acid amide or higher alkylamine is 20 or less.

  According to the mask of the present invention, even when harmful substances or malodorous components floating in the air are finer than the eyes of the breathable nonwoven fabric constituting the cover part, when passing through the cover part Further, by being adsorbed by the liquid impregnated in the liquid-impregnated sheet sandwiched between the cover portions, it is possible to prevent the harmful substances and the like from being inhaled from the nostril or mouth. Therefore, by wearing this mask, it is possible to effectively prevent inhalation of dust, pathogens such as bacteria and viruses, pollutants and other harmful substances and pollutants, as well as malodorous components, etc. It is effective in preventing diseases such as colds, hay fever, and malodor. Moreover, contrary to the above, it is possible to prevent the wearer's halitosis component, the pathogenic bacteria possessed by the wearer, and the like from being expelled together with exhaled breath and spreading to the surroundings, which also has the effect of preventing halitosis and preventing the spread of pathogenic bacteria. Furthermore, the liquid-impregnated sheet improves the moisture retention, prevents the wearer's throat from drying, and reduces the symptoms of bronchial diseases such as asthma. Therefore, not only when going out, but also indoors, for example, by wearing this mask at bedtime, it is possible to sleep in a refreshing feeling without worrying about air pollution and bad breath in the room.

  In the mask of the present invention, the inner surface side of the cover part is covered with a non-hygroscopic woven fabric or a non-woven fabric, or the cover part itself is made of a non-hygroscopic non-woven fabric or the like. The liquid impregnated in the sandwiched liquid-impregnated sheet does not ooze out from the cover and wets the wearer's nose, mouth, etc., and gives discomfort.

  Furthermore, since the liquid is non-volatile or a low-volatile liquid having a boiling point of 120 ° C. or higher, it is difficult to be volatilized by the air passing through the mask body during breathing. Adsorption effects such as malodorous components are maintained for a long time. The liquid impregnated in the liquid-impregnated sheet needs to be liquid when using a mask. For example, when used in an extremely cold environment, the liquid does not freeze even in such an extremely cold environment. It is necessary to use one having a melting point capable of maintaining a liquid state.

  Furthermore, the mask according to the present invention has a simple structure in which a non-hygroscopic woven fabric or non-woven fabric is stacked on the inner surface side, or a liquid-impregnated sheet is sandwiched between a cover portion made of a non-hygroscopic non-woven fabric. Therefore, it is not necessary to use a high-performance and expensive material as the material, and the high-performance mask as described above can be manufactured at a relatively low cost.

  In addition, if the cover portion is formed in a three-dimensional shape that does not adhere to the mouth and nostril, the wearing feeling can be improved and the mask can be reliably prevented from sliding off the face due to the weight of the liquid-impregnated sheet.

  The cover is provided with a pocket that opens upward or laterally, and the mask in which the liquid-impregnated sheet is accommodated in the pocket is only easy to mount the liquid-impregnated sheet on the cover. Alternatively, the mask can be used repeatedly by attaching and detaching the liquid-impregnated sheet to the cover or replacing the liquid-impregnated sheet.

  By overlaying a nonwoven fabric made of at least one thermoplastic resin selected from the group consisting of a polyester resin, a polyolefin resin and a nylon resin on the inner surface side of the covering portion, or forming the covering portion with the nonwoven fabric. The liquid impregnated in the liquid-impregnated sheet sandwiched between the cover parts does not migrate to the non-hygroscopic nonwoven fabric located on the inner surface side of the cover part, and the liquid starts to ooze out from the cover part and It is possible to reliably prevent discomfort by wetting around the mouth.

  When the liquid-impregnated sheet is composed of a hygroscopic nonwoven fabric, in particular, a nonwoven fabric made of cotton, rayon, or a blend of thermoplastic synthetic fibers with them, the liquid-impregnated sheet can be easily impregnated with liquid. At the same time, the impregnated liquid is securely held by the liquid-impregnated sheet and does not ooze out from the cover and wet the wearer's nose, mouth periphery, and the like.

  As the liquid, at least one polyhydric alcohol selected from the group consisting of glycerin, polyerylene glycol, polypropylene glycol, 1,3-butanediol, 1,4-butanediol, and 1,5-pentanediol is used. In such a case, these polyhydric alcohols have no or very little evaporation loss with time, and conversely have the property of absorbing and increasing the amount of moisture from the air, thereby improving the moisture retention of the mask. Further, these polyhydric alcohols have very low toxicity, are harmless to the wearer, and are odorless, so that the wearing feeling is not impaired.

  As the impregnation liquid, the polyhydric alcohol may be used alone, or two or more kinds may be mixed and used, or the polyhydric alcohol and water may be mixed and used.

  By adding a compound having at least one action of deodorizing, sterilizing, antibacterial and antiviral to the impregnating solution, the deodorizing effect by the liquid is improved, and adsorbed bacteria, viruses and the like are absorbed by the compound. It is detoxified and can more reliably prevent infections caused by diseases such as bacteria and viruses.

  As the compound, a nitrogen-containing nonionic surfactant, for example, at least one nitrogen-containing nonionic surfactant selected from the group consisting of polyoxyethylene fatty acid amide, polyoxyethylene alkylamine, alkylamine oxide, and fatty acid alkanolamide By using an agent, particularly polyoxyethylene fatty acid amide and polyoxyethylene alkylamine, both the deodorizing effect and the bactericidal effect can be exhibited simultaneously. The polyoxyethylene fatty acid amide and polyoxyethylene alkylamine are slightly different from general nonionic surfactants and have weak cationic activator properties, and the higher fatty acid amide and higher alkylamine have 12 to 24 carbon atoms. Thus, a condensate having an ethylene oxide addition mole number of 20 or less has a cationic property as described above, and a low molar adduct of ethylene oxide has a strong tendency. Therefore, as the compound used in the present invention, a higher fatty acid amide or a higher alkylamine preferably has 12 to 24 carbon atoms and an ethylene oxide addition mole number of 20 or less. Particularly, the higher fatty acid amide or higher alkylamine has a carbon number of 20 or less. Those having 12 to 18 and an added mole number of ethylene oxide of 10 or less are more preferable.

  When the compound contained in the liquid is a paraoxybenzoic acid ester, a bactericidal effect, an antifungal effect, and further an effect of removing malodors and harmful components such as ammonia, hydrogen sulfide, formalin and the like are exhibited. As the paraoxybenzoic acid ester, methyl paraoxybenzoate, ethyl paraoxybenzoate, propyl paraoxybenzoate, butyl paraoxybenzoate, benzyl paraoxybenzoate, isopropyl paraoxybenzoate, and isobutyl paraoxybenzoate can exhibit the above effects. It is preferable because of its low toxicity to the human body.

  Furthermore, the combined use of the nitrogen-containing nonionic surfactant and paraoxybenzoic acid ester can simultaneously exhibit the effects of both the deodorizing effect, the bactericidal effect, the antifungal effect, and the foul odor preventing effect. .

  1 is a perspective view showing an embodiment of a mask according to the present invention, FIG. 2 is a plan view, and FIG. 3 is a longitudinal sectional view. The mask 1 includes a breathable cover portion 2 having a shape and size capable of covering the mouth and nostrils, a pair of ear hooks 3 and 3 provided on both sides of the cover portion 2, and a conventional one. It has the same basic structure as a general mask. As shown in FIGS. 1 and 3, the cover 2 is formed in a three-dimensional shape so as not to adhere to the mouth m and the nostril n. In addition, the shape of the cover part 2 is not limited to the example of a figure, It can form in various three-dimensional shapes. Furthermore, the cover part 2 does not necessarily have a three-dimensional shape. For example, as shown in FIG. 4, the cover part 2A may have a planar shape. Moreover, in the mask 1 shown in FIGS. 1-3, the ear hooking parts 3 and 3 which have the hole 4 which hooks an ear | edge are integrally formed in the both sides of the cover part 2, but like the mask 1A shown in FIG. Further, ear covering portions 3A and 3A made of a stretchable material such as a rubber string may be provided on both sides of the covering portion 2A.

  Non-hygroscopic nonwoven fabrics W and W are stacked on the cover 2, and a pocket P opening upward is provided. The liquid impregnated sheet 5 is accommodated in the pocket P. In the illustrated masks 1 and 1A, the cover portions 2 and 2A are in a state in which one nonwoven fabric is folded, and both side edges thereof are bonded or fused to form a pocket P that opens upward. Two non-woven fabrics may be overlapped, and the lower end edge and both side edges thereof may be bonded or fused to provide a pocket P opened upward, as long as the liquid-impregnated sheet 5 can be sandwiched inside. . Further, in the illustrated masks 1 and 1A, the cover portions 2 and 2A are formed by doubling the nonwoven fabric and sandwiching the liquid-impregnated sheet 5 therebetween, but the inner surface side or the outer surface of the cover portions 2 and 2A. The side may be a structure in which two or more nonwoven fabrics are stacked. Furthermore, the pocket P may be opened to the side of the cover part 2, and in that case, it may be opened to both sides.

  The cover portion 2 is made of a non-hygroscopic nonwoven fabric made of a thermoplastic resin such as a polyester resin, a polyolefin resin, or a nylon resin. Examples of the polyester nonwoven fabric include trade name “Bonden” manufactured by Toyobo Co., Ltd. Examples of the polyolefin-based non-woven fabric include a trade name “Strex latex” which is a polypropylene spunbonded non-woven fabric manufactured by Idemitsu Unitech Co., Ltd., for example, “Strex RW2070”, a core portion of polyester, and a sheath portion of polyethylene core. Examples thereof include an olefin-based spunbonded nonwoven fabric made of sheath double structure fibers, such as “Elves” manufactured by Unitika Ltd. Furthermore, as the nylon-based nonwoven fabric, a trade name “NIACE” which is a nylon-based spunbonded nonwoven fabric manufactured by Unitika Co., Ltd. may be mentioned.

  The liquid-impregnated sheet 5 is large enough to be accommodated in the pocket P of the cover 2 and preferably large enough to cover both the mouth m and the nostril n. The liquid-impregnated sheet 5 is made of a hygroscopic nonwoven fabric, and is made of cotton, rayon, a nonwoven fabric made of a blend of thermoplastic synthetic fibers, and the like. Examples of the cotton-based non-woven fabric include trade name “Cot Ace” which is a cotton non-woven fabric manufactured by Unitika Ltd., for example, “Cot Ace C110S / 26” (100% cotton). Examples of the non-woven fabric made of the rayon-based non-woven fabric or a blend of rayon and polyester include “Travelon” manufactured by Kanai Important Industry Co., Ltd.

  The liquid impregnated in the liquid-impregnated sheet 5 is non-volatile or a liquid having a boiling point of 120 ° C. or higher. Such a liquid does not evaporate in a short time due to breathing when wearing a mask, and the inhalation preventing effect and deodorizing effect of harmful substances and pollutants last for a long time of 10 hours or more. Moreover, since the impregnating liquid is volatilized to some extent by the intake air passing through the adsorption layer and may be inhaled together with the intake air, it is preferable to use a non-irritating odorless liquid and a low toxicity liquid. Furthermore, from the viewpoint of ease of production, it is preferable that the liquid has a viscosity that can be easily impregnated into the hygroscopic nonwoven fabric at room temperature. Furthermore, in an extremely cold environment application, it is necessary to use one having a melting point capable of maintaining a liquid state without freezing during use.

  As the impregnation liquid, for example, polyhydric alcohols such as glycerin, polyerylene glycol, polypropylene glycol, 1,3-butanediol, 1,4-butanediol, and 1,5-pentanediol are preferably used. Glycerin is transparent and in a molasses state, is a non-volatile liquid having a boiling point of 290 ° C., is particularly strong and has excellent moisture retention. Polyethylene glycol is a non-volatile liquid and has a hygroscopic property. Polypropylene glycol is a non-volatile liquid and is commonly used as a humectant. 1,3-butanediol has a boiling point of 207 ° C. and is hygroscopic and absorbs 25% over 400 hours. 1,4-butanediol has a boiling point of 228 ° C. and is mixed with water at an arbitrary ratio. 1,5-pentanediol has a boiling point of 238 ° C. and is mixed with water at an arbitrary ratio. These polyhydric alcohols do not lose evaporation over time and, conversely, absorb moisture from the air over time and increase the amount, improving the moisturizing effect of the mask. These polyhydric alcohols are suitable as liquids to be impregnated in the liquid-impregnated sheet because they have low toxicity, do not cause harm to the wearer, and are odorless. These polyhydric alcohols may be used alone or in combination of two or more. Furthermore, it is also a preferred embodiment that the viscosity and boiling point are adjusted as appropriate by mixing with water.

  Furthermore, if the liquid impregnated in the liquid impregnated sheet 5 contains a compound having at least one action of deodorizing, sterilizing, antibacterial and antiviral, the liquid impregnated sheet is added to the liquid impregnated sheet when passing through the cover 2. Malodorous components adsorbed on the impregnated liquid, pathogenic bacteria such as bacteria and viruses, and the like can be rendered non-brominated and harmless by these compounds.

  As the compound, for example, a nitrogen-containing nonionic surfactant can be used. Examples of the nitrogen-containing nonionic surfactant include polyoxyethylene fatty acid amide, polyoxyethylene alkylamine, alkylamine oxide, and fatty acid alkanolamide. These nitrogen-containing nonionic surfactants are used alone. Or 2 or more types can also be mixed and used. Among these, polyoxyethylene fatty acid amide or polyoxyethylene alkylamine is more preferable. Further, in this case, the fatty acid amide in the polyoxyethylene fatty acid amide or the higher alkylamine in the polyoxyethylene alkylamine has 12 to 24 carbon atoms, and addition of ethylene oxide to the fatty acid amide or higher alkylamine Those having a mole number of 20 or less are particularly preferred. This nitrogen-containing nonionic surfactant has an excellent sterilizing effect on both food poisoning gram-negative bacterium Escherichia coli and gram-positive staphylococcus aureus, and sterilizes MRSA bacteria quickly so that it can be disinfected. Excellent deodorizing effect because it completely sterilizes spoilage bacteria, and this nitrogen-containing nonionic surfactant has a boiling point of 250 ° C or higher, and maintains deodorizing power and bactericidal power for a long time. Can do. This nitrogen-containing nonionic surfactant has been approved as a plastic additive for food packaging containers as a pigment dispersant, antistatic agent, etc., and has also passed Ministry of Health and Welfare Notification No. 370 (Japan). Low toxicity has been proven.

  Among the nitrogen-containing nonionic surfactants, polyoxyethylene fatty acid amide (higher fatty acid amide condensate) is an addition polymer of ethylene oxide to higher fatty acid amide or a dehydration condensate of higher fatty acid amide and polyethylene glycol. It is a nonionic surfactant having cationic properties, produced by addition polymerization of ethylene oxide to two active hydrogens bonded to the nitrogen group of higher fatty acid amide or by dehydration condensation of polyethylene glycol. Polyoxyethylene alkylamine (higher alkylamine condensate) is a weakly cationic nonionic surfactant obtained by condensing ethylene oxide with a higher alkylamine in which two active hydrogens bonded to a nitrogen group are present. . Thus, polyoxyethylene fatty acid amides and polyoxyethylene alkylamines are slightly different from general nonionic surfactants and have weak cationic surfactant properties, and higher fatty acid amides and higher alkylamines have 12 carbon atoms. The condensate having an addition mole number of ethylene oxide of 20 or less has a cationic property as described above, and a low mole addition product of ethylene oxide has a strong tendency. Therefore, as a compound used in the present invention, naturally, a higher fatty acid amide or higher alkylamine having 12 to 24 carbon atoms and an ethylene oxide addition mole number of 20 or less is desirable. More preferably, the number is 12 to 18 and the number of added moles of ethylene oxide is 10 or less. These polyoxyethylene fatty acid amides and polyoxyethylene alkylamines are water-soluble by appropriately selecting and adjusting the production method, particularly the types of higher fatty acid amides and higher alkylamines and the number of moles of ethylene oxide added. In addition, since it has the feature that it can be freely synthesized even those that are hardly soluble in water and soluble in alcohol, hydrocarbon, and other organic solvents, it can be easily mixed with the liquid to be impregnated in the liquid-impregnated sheet 5. .

  The content of the nitrogen-containing nonionic surfactant in the impregnating liquid is not particularly limited, but it is preferably 0.05% by weight or more based on the liquid, while it is added in excess of 1% by weight. However, the effect is saturated and only the cost is increased.

  Further, as the compound to be contained in the impregnating liquid, paraoxybenzoic acid such as methyl paraoxybenzoate, ethyl paraoxybenzoate, propyl paraoxybenzoate, butyl paraoxybenzoate, benzyl paraoxybenzoate, isopropyl paraoxybenzoate, isobutyl paraoxybenzoate, etc. Esters can also be used.

  The blending amount of paraoxybenzoic acid ester with respect to the impregnating liquid is preferably 0.01% by weight or more. Below this, the effect is difficult to be exhibited. Moreover, even if it contains exceeding 1 weight%, an effect will be saturated and it will only raise a cost.

  It is also effective to use a nitrogen-containing nonionic surfactant such as polyoxyethylene alkylamine and the paraoxybenzoic acid ester in combination. For example, an impregnating solution composed of 80% by weight of 1.3-butenediol and 20% by weight of water contains 0.2% by weight of each of the nitrogen-containing nonionic surfactant and the paraoxybenzoic acid ester. It is impregnated into a hygroscopic nonwoven fabric and used as a liquid-impregnated sheet 5 in the pocket P of the cover portion 2 made of a non-hygroscopic nonwoven fabric.

  Further, the impregnating liquid may contain other known disinfectants and antibacterials instead of or in combination with the nitrogen-containing nonionic surfactant and paraoxybenzoic acid ester having the deodorizing effect and the bactericidal effect as described above. Agent, antiviral agent can be contained. For example, effective infection and prevention of influenza include azithromycin hydrate as an antibiotic, amantadine hydrochloride as an anti-influenza A virus agent, zanamivir hydrate as an anti-influenza agent, and oseltamivir phosphate as well. Can be mentioned. As for tuberculosis infection and prevention, anti-tuberculosis chemotherapeutic agent, paraaminosalicylate calcium, tuberculosis chemotherapeutic agent pyrazinamide, isoniazid, isoniazid metasulphonate sodium, also ethambutol hydrochloride, ethinamide, antituberculosis agent. Examples include calcium aluminoparaaminosalicylate. In addition, parabens, cationic surfactants and the like are also effective. Although there is no restriction | limiting in particular in the usage-amount of these disinfectants etc., 0.01-20 weight part is dissolved or disperse | distributed and used with respect to 100 weight part of impregnating liquids. These bactericides and antiviral agents can be used alone or in combination depending on the purpose of use of the mask.

  According to the mask 1 according to the present invention as described above, even if malodorous components, harmful substances, pollutants, etc. floating in the air pass through the non-hygroscopic nonwoven fabric W constituting the covering portion 2, etc. When passing through the liquid-impregnated sheet 5 sandwiched between the nonwoven fabrics W, W of the covering portion 2, the liquid impregnated in the liquid-impregnated sheet 5 is adsorbed and removed, and bad odor components, harmful substances, pollutants, etc. are sucked in. In addition, inhalation from the nostril or mouth can be prevented. On the other hand, bad breath components and viruses such as viruses contained in the breath exhaled from the mouth of the wearer are also captured by the impregnating liquid when passing through the liquid impregnated sheet 5, and the mask wearer Prevents bad breath and germs from being scattered around. Moreover, since the impregnating liquid is non-volatile or low volatile with a boiling point of 120 ° C. or higher, the impregnating liquid is hardly volatilized even by exhaled air (air) passing through the cover 2 and the effect is maintained for a long time. Therefore, by wearing the mask 1 of the present invention, it is possible to prevent infections of diseases such as colds and influenza and the onset of hay fever.

  Further, the mask 1 can be easily manufactured simply by accommodating the liquid-impregnated sheet 5 in the pocket P of the covering portion 2 made of a nonwoven fabric, and a high-functional material or a complicated structure and an expensive one are used. This is unnecessary, and a high-performance mask can be manufactured at a relatively low cost. Furthermore, the mask 1 containing the liquid-impregnated sheet 5 impregnated with the liquid in the pocket P provided in the cover part 2 is easy to attach and detach the liquid-impregnated sheet 5, and also impregnates different liquids or different compounds. If various liquid-impregnated sheets 5 impregnated with a liquid containing liquid are prepared, masks of other varieties having various functions according to the purpose can be easily manufactured.

  In the illustrated masks 1 and 1A, the liquid impregnated sheet 5 impregnated with the liquid is accommodated in the pockets P provided in the cover 2 made of the double nonwoven fabrics W and W, but the present invention is not limited to this. Instead of this, the liquid impregnated sheet 5 may be sandwiched between a plurality of nonwoven fabrics W constituting the cover 2 and bonded, welded, or stitched.

  Furthermore, in the illustrated masks 1 and 1A, only one liquid-impregnated sheet 5 is sandwiched between the non-woven fabrics W, W constituting the covering portion 2, but a plurality of liquid-impregnated sheets 5 may be sandwiched. In this case, the liquid impregnated in each liquid-impregnated sheet 5 may be the same or different liquid, and further, those containing or not containing a compound such as a deodorizing agent or disinfectant, Any combination of these may be used.

  Further, if the cover 2 is further provided with a deodorizing layer in addition to the liquid-impregnated sheet 5 as described above, odor components in the air are also adsorbed to the deodorizing layer and are not inhaled together with intake air. . The deodorizer used is not particularly limited, and known inorganic deodorizers represented by activated carbon, silica gel, zeolite and the like can be used. For example, the deodorizer may be accommodated in a bag made of a non-woven fabric having air permeability and sandwiched between the non-woven fabrics W constituting the covering portion 2. As a result, the liquid-impregnated sheet 5 when malodorous components, pollutants, harmful substances, etc. floating in the air, or bad breath components or pathogenic bacteria that are expelled from the wearer's mouth along with exhalation pass through the cover 2. In addition to being adsorbed by the liquid, the deodorizing layer simultaneously provides a mask with further excellent deodorizing effects. Further, by attaching a bag body filled with an inorganic deodorizing agent to a pocket provided in the cover portion 2 in the same manner as the liquid-impregnated sheet 5, a mask provided with a deodorizing layer can be easily manufactured. It can also be removed and replaced.

  Further, in the illustrated masks 1 and 1A, the cover portions 2 and 2A themselves are made of a non-hygroscopic nonwoven fabric, and the liquid-impregnated sheet 5 is sandwiched inside. However, the cover part 2 does not necessarily have to be made of a non-hygroscopic material, and is conventionally used in general, and the cover part is an inner surface side of a cotton mask made of a plurality of stacked cotton cloths, that is, In addition, the sheet made of the non-hygroscopic material as described above is stacked on the side of the wearer's nose or mouth, and the liquid-impregnated sheet as described above is inserted between the covered cotton cloths. It may be used with pinching. In the above case, in order to prevent the non-hygroscopic sheet stacked on the inner surface side of the cover part from falling off from the cover part, it is bonded to the cover part or sewn without impairing the air permeability. May be. Furthermore, the sheet made of the non-hygroscopic material is inserted between the cotton cloths of the cotton mask and sandwiched between the cotton cloths, and the outer side of the sheet made of the hygroscopic material, that is, the wearer The liquid impregnated sheet may be sandwiched between cotton cloths on the side away from the face. Further, the non-hygroscopic sheet or the liquid-impregnated sheet may be adhered to or sewn to the cotton cloth of the cover part in order to prevent the sheet from falling off the cover part.
