Description

  The present invention relates to a mask, and more specifically, it can effectively prevent inhalation of pollutants and harmful substances such as dust floating in the air, pathogens such as bacteria and viruses, and even pollen, dust proof, deodorant, disease The present invention relates to a mask that is effective in preventing infections and preventing hay fever.

  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 has increased, and influenza such as sick house syndrome, thirs, and hay fever have become social problems, and the necessity and importance of masks have increased to prevent inhalation of the harmful substances and pollutants. ing.

  A general-purpose mask currently on the market is a gauze mask in which the body covering the nostril and mouth is made of gauze, and elastic ear hooks made of rubber strings are provided on both sides thereof. . Disposable masks whose main body is made of nonwoven fabric or the like are also commercially available. In these masks, when inhalation passes through the gauze and nonwoven fabric of the mask body during breathing, harmful substances and pollutants such as dust, pathogens and pollen in the air are filtered by the gauze and nonwoven fabric. Inhalation from the nostrils and mouth. For this reason, conventionally, the gauze of the main body which covers a nostril and a mouth, and the eyes of a nonwoven fabric are made as small as possible, and the device which does not let through the harmful substances in the above air as much as possible has been made | formed.

  In addition to preventing inhalation of substances in the air along with inhalation during breathing, water (humidity) is applied to the mask body for the purpose of preventing colds, other diseases, and preventing hay fever. There has also been proposed a mask in which moisture and medicine are inhaled together with inhalation.

  For example, a wet mask method has been proposed in which a gauze of a mask body is wet and air is humidified to prevent a cold or the like (see Non-Patent Documents 1 and 2). In addition, a mask (see Patent Document 1) in which a container filled with a drug such as a dried medicinal plant is attached to the mask body (see Patent Document 1), a drug in gauze, or a drug in a pocket made between gauze A medicinal mask (see Patent Document 2) containing a volatile drug, and a volatile drug sustained-release mask in which a powder in which a volatile drug is included in cyclodextrin is attached to the gauze of the mask body (Patent Document 3) reference.). A menthol-containing mask provided with a menthol sustained-release holding body composed of microporous hollow fibers containing menthol (see Patent Documents 4, 5, 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 6), and water-containing substances soaked with water and drugs can be stored in a plastic bag with many vents and put in and out of the mask body Moisture inhalation mask (refer to Patent Document 7) A method for eliminating discomfort caused by fragrance by spraying a fragrance solution such as mint essence, menthol, hinokitiol on the inside of the mask just before wearing to cover the nostril (Patent Document) 8), a volatile agent such as menthol or ethanol is impregnated into a hygroscopic sheet, and this is wrapped in a perforated packaging material, and a mask (patent) 9)), volatile compounds such as ethanol, butyl alcohol, menthol and other monohydric alcohols, volatile sulfides, acids, basic compounds, trihalomethane, etc. that physiologically dysfunctional upper airway mucosal cells are masked A method for treating colds and hay fever by inhalation (see Patent Document 10) has also been proposed.

  However, the various harmful substances and pollutants 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. It is difficult to effectively prevent the inhalation of such fine harmful substances by making fine eyes such as mask gauze and non-woven fabric, and even 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 narrow the eyes of gauze and nonwoven fabric covering the nostrils and mouth, but if the eyes of gauze and nonwoven fabric are too fine, the breathability becomes extremely low and the breathing becomes difficult There is.

  All masks such as gauze that contain moisture and drugs will prevent or treat diseases such as colds and hay fever by volatilizing the moisture and drugs by breathing and inhaling with inhalation. As the drug, the volatile component as described above is used. Therefore, these conventional masks are expected to be sufficiently effective in preventing inhalation of extremely fine harmful substances and contaminants floating in the air, even though they can inhale moisture and drugs. Can not.

  In view of the problems of the conventional mask as described above, the present invention is effective in inhaling extremely fine harmful substances and pollutants such as dust, bacteria, viruses and other pathogens floating in the air, and pollen. It is an object of the present invention to provide a mask that can be easily prevented and that can be used to prevent colds and hay fever, and that can be manufactured without using high-performance and expensive materials.

  The mask according to the present invention has a breathability obtained by applying or impregnating a mask body made of a breathable cloth or sheet covering the nostril and mouth with a liquid having a boiling point of 120 ° C. or higher when the mask is used. An adsorbing layer made of a cloth or a sheet is provided.

  According to the mask according to the present invention as described above, even if the harmful substance floating in the air is finer than the eyes of the breathable cloth or sheet constituting the mask body, the mask body is provided. When passing through the adsorbing layer, it is adsorbed by the liquid of the adsorbing layer, so that the harmful substance can be prevented from being inhaled from the nostril or mouth. Therefore, in the mask of the present invention, the liquid applied or impregnated in the adsorption layer needs to be a liquid when the mask is used. For example, when used in an extremely cold environment, such a liquid is used as the liquid. It is necessary to use one having a melting point capable of maintaining a liquid state without freezing even in an environment. In addition, since the liquid has a boiling point of 120 ° C. or higher and low volatility, it is difficult to be volatilized by the air passing through the mask body during breathing, and the above-mentioned harmful substances and pollutants can be adsorbed for a long time. Maintained over.

  The adsorbing layer of the mask body may be provided by sandwiching a cloth or sheet coated or impregnated with the liquid between a breathable cloth or sheet of the mask body. Furthermore, a pocket may be provided in the mask body, and a cloth or a sheet coated or impregnated with the liquid may be attached to the pocket to form an adsorption layer.

  If the liquid of the adsorption layer contains at least one of a bactericidal agent, an antibacterial agent and an antiviral agent, bacteria or viruses adsorbed on the liquid by the bactericidal agent, antibacterial agent, antiviral agent, etc. It can be detoxified.

  In addition, the deodorizing effect is greatly improved by the adsorption layer using the liquid-impregnated cloth, but if an inorganic deodorizing agent is used in combination with the mask body, odor components in the air are also adsorbed by the deodorizing layer and inhaled together with the intake air. There is nothing to do. An inorganic deodorizing agent can be used for the deodorizing layer. When the inorganic deodorant is used, it can be filled into a bag having air permeability and sandwiched between a cloth or a sheet of the mask body to form a deodorizing layer. Furthermore, you may make it mount | wear with the bag provided with the said inorganic deodorizer in the pocket provided in the mask main body.

  According to the mask according to the present invention as described above, even if harmful substances and contaminants floating in the air are finer than the eyes of the breathable cloth or sheet constituting the mask body, the mask When passing through the adsorption layer provided on the main body, it is adsorbed by the liquid of the adsorption layer, so that the harmful substances can be prevented from being inhaled from the nostril or mouth, and the effect is maintained for a long time. . Therefore, wearing this mask can effectively prevent inhalation of harmful substances and pollutants such as dust, bacteria, viruses and other pathogens in the air, pollen, etc. Effective in preventing hay fever. Further, the mask according to the present invention can be produced simply by providing the adsorption layer on a conventional general gauze mask or a mask made of non-woven fabric, and it is necessary to use a particularly high-function and expensive mask material. Therefore, a high-performance mask can be manufactured at a relatively low cost.

  Further, a mask having an adsorbing layer can be easily manufactured by sandwiching a cloth or sheet coated or impregnated with the liquid between a breathable cloth or sheet of the mask main body. Furthermore, if a pocket is provided in the mask body and a cloth or sheet coated or impregnated with the liquid is attached to the pocket to form an adsorption layer, the adsorption layer can be easily provided, and the adsorption layer can be attached and detached. And can be exchanged.

  The liquid of the adsorption layer contains at least one of a bactericidal agent, an antibacterial agent and an antiviral agent, and the bacteria, viruses, etc. adsorbed on the liquid are rendered harmless by the bactericidal agent, the antibacterial agent and the antiviral agent. By doing so, infection of diseases caused by bacteria and viruses can be prevented more reliably.

  Further, if a deodorizing layer is further provided on the mask body, an odor component in the air is adsorbed on the deodorizing layer and is not inhaled together with the intake air, so that the mask has an excellent deodorizing effect. If an inorganic deodorant is used for the deodorizing layer, the deodorizing layer can be provided at a low cost. Furthermore, a mask having a deodorizing layer can be produced simply by filling the inorganic deodorizing agent into a bag having air permeability and sandwiching the bag with a cloth or a sheet of the mask body. Furthermore, if the bag body filled with the inorganic deodorizing agent is mounted in a pocket provided in the mask body, the deodorizing layer can be attached or detached or exchanged.

  FIG. 1 shows an embodiment of a mask according to the present invention. The mask 1 is provided with a pair of ear hooks 3 and 3 on both sides of the mask body 2 covering the nostril and mouth, and has the same basic configuration as a conventional general mask. The mask body 2 is made of a breathable cloth or sheet. As the cloth or sheet constituting the mask main body 2, gauze, non-woven fabric or the like can be used in the same manner as a conventional general mask. The ear hooks 3 and 3 can be made of a stretchable material such as a rubber string as in the conventional mask. And the inside of the mask main body 2 is provided with an adsorbing layer 4 made of a breathable cloth or sheet that is coated or impregnated with a liquid having a boiling point of 120 ° C. or higher when the mask is used. In the mask 1 shown in the figure, the adsorbing layer 4 is formed by sandwiching a cloth or sheet coated or impregnated with a liquid between the gauze 2a and 2a constituting the mask main body 2. Further, the adsorbing layer 4 is provided with a pocket 5 by folding the gauze (a plurality of layers) constituting the mask body 2 in such a manner that the ends thereof are on the upper side, and the liquid is applied to the pocket 5. Alternatively, the impregnated gauze 6 (a plurality of stacked ones) is attached, and the adsorption layer 4 is provided between the gauze 2a and 2a.

  As the cloth or sheet having air permeability constituting the adsorbing layer 4, it is possible to use the same layered gauze as the mask body 2, but further use a nonwoven fabric or a sponge-like material having open cells. You can also

  The liquid applied or impregnated into the adsorption layer has a boiling point of 120 ° C. or higher and low volatility. By using a coating or impregnating liquid having a boiling point of 120 ° C. or higher, it does not evaporate in a short time due to breathing when wearing a mask, and prevents inhalation of harmful substances and pollutants over a long period of 10 hours or more. Persists. Further, since the coating or impregnating liquid may be 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, a liquid having a viscosity that can be easily applied or impregnated into gauze or the like at room temperature is preferable. 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.

  Examples of the coating or impregnating liquid include phthalic acid esters, aliphatic dibasic acid esters, and positive oils used as plasticizers for thermoplastic resins such as vegetable oils, mineral oils, synthetic oils, surfactants, and vinyl chloride resins. Specific examples include non-ionic surfactants such as glycerin, glycols, 1,3-butanediol, liquid paraffin, polyoxyethylene alkyl ether, sorbitan fatty acid ester, polyoxyethylene fatty acid ester, and the like. Agents, dibutyl sebacate, 2-ethylhexyl diphenyl phosphate, and polybutene.

  Further, if the liquid of the adsorption layer 4 contains a bactericidal agent, an antibacterial agent, an antiviral agent, etc., the bacteria or viruses adsorbed on the adsorption layer 4 can be converted into such a bactericidal agent, antibacterial agent, antiviral agent, etc. Can be rendered harmless. As the antibacterial agent and antibacterial agent m antiviral agent, known ones can be used. For example, effective infection and prevention of influenza include azithromycin hydrate, which is an antibiotic, amantadine hydrochloride, which is an anti-influenza A virus agent, zanamivir hydrate, which is also an anti-influenza agent, and oseltamivir phosphate. Can be mentioned. As for the infection and prevention of tuberculosis, anti-tuberculosis chemotherapeutic agent paraaminosalicylate calcium, tuberculosis chemotherapeutic agent pyrazinamide, isoniazid, isoniazid metasulphonate sodium, also ethambutol hydrochloride, also etionamide, antituberculous agent Examples include calcium aluminoparaaminosalicylate. In addition, parabens and cationic surfactants are also effective. Although there is no restriction | limiting in particular in the usage-amount of these disinfectants, For example, 0.01-20 weight part is dissolved or disperse | distributed with respect to 100 weight part of liquid applied or impregnated to the adsorption layer 4, and is used. In addition, the above bactericides 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 when harmful substances and pollutants floating in the air pass through the adsorbing layer 4 even though they pass through the gauze 2 a constituting the mask body 2. It is adsorbed and removed by the liquid applied or impregnated on the gauze 6 to prevent harmful substances and pollutants from being inhaled from the nostril or mouth together with inhalation. Moreover, since the boiling point of the liquid of the adsorption layer 4 is 120 ° C. or more and low volatility, it is hardly volatilized even by respiration passing through the mask body 2, and the effect lasts for a long time. Therefore, wearing the mask 1 can prevent infection of diseases such as colds and influenza, and onset of hay fever. Moreover, since the mask 1 can be easily manufactured simply by providing the adsorption layer 4 on a conventional general gauze mask or a mask made of nonwoven fabric, it is necessary to use a particularly high-functional and expensive mask material. Thus, a high-performance mask can be manufactured at a relatively low cost.

Further, the adsorbing layer 4 can be easily provided by sandwiching the gauze 6 coated or impregnated with liquid between the gauze 2a, 2a of the mask body 2, and further provided on the mask body 2 as shown in the figure. If the gauze 6 coated with liquid or impregnated in the pocket 5 is attached to form the adsorption layer 4, not only the mask 1 can be easily manufactured, but also the attachment / detachment and replacement of the adsorption layer 4 can be easily performed. A mask provided with various adsorbing layers 4 can be easily manufactured only by preparing a gauze 6 coated or impregnated with a liquid or coated or impregnated with a liquid containing a different sterilizing agent.

  In the embodiment shown in FIG. 1, the pocket 5 is provided in the mask body 2 made of the gauze 2a and the gauze 6 or the like coated or impregnated with the liquid is attached to form the adsorbing layer 4. However, the present invention is not limited to this. Instead, the adsorption layer 4 may be integrally formed on the mask body 2 by applying or impregnating the liquid as described above to a part of a plurality of layers of gauze constituting the mask body 2. In this case, it is preferable that the gauze in the inner layer of the mask body 2 is used as the adsorption layer 4 so that the adsorption layer 4 does not directly contact the nose or mouth of the face. Further, an adsorbing layer 4 formed by applying or impregnating the liquid onto a cloth body or sheet body such as gauze 6 as shown in the mask 1A shown in FIG. Further, gauze 7 or the like may be further overlapped on the inside, or the adsorption layer 4 may be wrapped with gauze 7 and overlapped on the inside of the mask body 2 for use.

  Further, in the masks 1 and 1A, only one adsorption layer 4 is provided, but a plurality of layers may be provided. In this case, the liquid applied or impregnated in each adsorption layer 4 is the same or different. It may be a liquid, and further may be any one including, not including, or a combination of including a bactericidal agent.

  Further, if a deodorizing layer is further provided on the mask body in addition to the adsorption layer 4 as described above, odor components in the air are adsorbed on the deodorization layer and are not inhaled together with the intake air. FIG. 3 shows one embodiment of such a mask 10. Like the mask 1, this mask 10 is provided with a pair of ear hooks 13 and 3 on both sides of a mask main body 12 covering the nostril and mouth, and has the same basic configuration as a conventional general mask. The mask body 12 is made of a breathable material such as gauze or non-woven fabric, and the ear hooks 3 and 3 are made of a stretchable material such as a rubber string. And in this mask 10, the adsorption layer 4 which consists of the gauze which apply | coated or impregnated the liquid whose boiling point is 120 degreeC or more inside the mask main body 2, and the deodorizing layer using the inorganic deodorizing agent inside the mask main body 2 17 is provided. In the mask 1 shown in the figure, the mask body 12 is provided with two pockets 15 and 16 opened upward, and a gauze in which liquid is applied or impregnated into the pocket 15 on the inner side (side facing the face) is attached to the adsorption layer 4. In the outer pocket 16, a bag body 19 having air permeability filled with an inorganic deodorizing agent 18 is attached and a deodorizing layer 17 is provided.

  The inorganic deodorizing agent 18 is not particularly limited, and those having a known deodorizing adsorption ability represented by activated carbon, silica gel, zeolite and the like can be used. Moreover, the raw material of the bag body 19 filled with the inorganic deodorant 18 may be any material having air permeability, and examples thereof include cloth and nonwoven fabric.

  According to the mask 10, contaminants and harmful substances floating in the air are adsorbed by the liquid of the adsorption layer 4 when passing through the gauze or the like of the mask main body 2, so that the harmful substances are emitted from the nostrils or mouth. Substances can be prevented from being inhaled, and the effect lasts for a long time. In addition, bactericides, antibacterial agents, antiviral agents, etc. are included in the liquid of the adsorption layer 4, and the bacteria and viruses adsorbed on the liquid are rendered harmless, thereby preventing infections caused by bacteria and viruses. An effect similar to that of the mask 1 can be obtained, which can be surely prevented. Furthermore, in the case of this mask 10, since the deodorizing layer 17 using the inorganic deodorizing agent 18 is provided, the odor component in the air is adsorbed by the inorganic deodorizing agent 18 of the deodorizing layer 17, and the deodorizing effect is excellent. It becomes a mask. Moreover, the deodorizing layer can be provided at low cost by using the inorganic deodorizing agent 18, and the deodorizing layer can be simply obtained by filling the bag body 19 having air permeability with the inorganic deodorizing agent 18 and sandwiching it between the mask bodies 12. 17 can be provided. Furthermore, if the bag body 19 filled with the inorganic deodorizing agent is attached to the pocket 16 provided in the mask body 2 to form the deodorizing layer 17, not only the mask 10 provided with the deodorizing layer 17 can be easily manufactured, but also the deodorizing layer 17 is provided. It can also be removed and replaced.

  The mask according to the present invention is not limited to the embodiment shown in FIG. 3, and the deodorizing layer 17 can be provided on both sides of the adsorption layer 14 inside and outside the mask body 12. Also, a plurality of adsorption layers 14 can be provided. In this case, the deodorizing agent or liquid in each layer may be the same type of disinfectant contained in the liquid, or a deodorizing layer using a different deodorizing agent, or applying or impregnating a different liquid or disinfectant. The adsorbed layers may be combined. Further, the bag body 19 of the deodorizing layer 17 and the adsorbing layer 14 such as gauze coated or impregnated with a liquid can be used by being superimposed on the inside of the mask body 12 in the same manner as the mask 1A shown in FIG.

  Hereinafter, the results of testing the effect of the mask according to the present invention will be shown as experimental examples and examples. The drugs used in the following experimental examples and examples are as shown in Table 1 below.

[Experimental Example 1]
The characteristics of various liquids (chemicals) used for the adsorption layer of the mask according to the present invention were examined as follows. Samples of various liquids shown in Table 2 were applied to gauze (7.5 × 10 cm, 12 sheets folded) as the stock solution, and the state after 10 hours at 37 ° C. was examined. The stickiness was determined by application. The residual rate was determined by measuring the weight of the liquid at the time of application with a balance, taking the weight as 100%, and measuring the weight after 10 hours at 37 ° C. The odor was judged by a sensory test. Moreover, the viscosity at 20 ° C. of each sample was also measured. The viscosity was measured with a single cylindrical rotational viscometer bismetron (model VG-A1, Yasuda Seiki Seisakusho). The results are shown in Table 2.

[Experiment 2]
The liquid diluted with water shown in Table 3 was applied to gauze (7.5 × 10 cm, 12 layers), and the residual ratio and wetness of the solution after 10 hours in a 37 ° C. air dryer were examined. The residual ratio (%) of the solution was obtained by measuring the weight of the liquid at the time of application with a balance, setting the weight to 100%, and measuring the weight after 10 hours at 37 ° C. Further, the wetness was determined by the touch of the fingertip. The results are shown in Table 3. The reason why the coating amount varies is that the optimal coating amount for gauze varies depending on each sample.

  As can be seen from Table 3, the results showed that glycerin-water and PEG-water are preferable as the liquid in the adsorption layer in terms of the remaining amount of liquid after the passage of time, the wetness, stickiness, and the like.

  The mask of the present invention was subjected to an odor test and a smoke test. Table 4 shows the mask, gauze, and nonwoven fabric used.

(2) As the liquid, glycerin or polyethylene glycol (PEG-200) was used, and the amount applied was 4 g.
(3) As the deodorizer, 1 g of activated carbon or zeolite-based deodorizer (Mizuka Sieves EX122) was put in a non-woven tea pack (7 × 8.5 cm) bag and sandwiched between masks.
(4) As a control, an N95 mask (manufactured by 3M) and a clean line Kowa (manufactured by Kowa Healthcare Co., Ltd.) were used in the same manner as in the above (1). However, uncoated gauze was not used, and only the polyethylene film was stacked and fixed with a rubber band.
(5) Evaluation method The odor from the beaker was judged numerically by assigning points according to the criteria shown in Table 5 below.

(Smoke test)
(1) The suction force of the handy type vacuum cleaner has been improved so that it is slightly stronger than that of humans. The mask shown in Table 4, gauze or non-woven fabric coated with liquid, and As shown in Table 6, the gauze was set in three layers in order from the outside, and fixed with vinyl tape so that there was no gap in the suction port.
(2) Burn the mosquito coil and place the mask at the tip of the suction port of the vacuum cleaner about 20cm above the place where the smoke is generated. After sucking for 10 minutes, the inner surface of the second layer of gauze or nonwoven fabric (the side of the suction port) The coloration state of (side) was determined. The same coating solution and deodorizer as those described in (2) and (3) of the odor test were used. In addition, the determination was made by assigning 3 points to the color of Comparative Example 1 in which the liquid-uncoated gauze was stacked in two layers on a mask that did not contain a deodorant, and as the point became thinner, it was set to 2 points and 1 point. The case was set to 0 points. As a control, an N95 mask and a clean light Kowa were used in the same manner as in the odor test (4).

  The results of the odor test and smoke test are shown in Table 6.

  As shown in Table 6, by using a gauze or non-woven fabric coated with a liquid, and further using an inorganic deodorizer, the amount of volatile components such as xylene and toluene and the permeation of smoke can be reduced. The effect of the mask became clear.

  Like the conventional general mask, the mask of the present invention is only worn with the nostril and mouth covered, and harmful substances such as dust, bacteria, viruses and other pathogens floating in the air, and pollen.
