The present invention relates to disposable masks, in particular disposable masks having anti-allergen and / or antiviral effects.

In recent years, the number of people with allergic diseases such as allergic rhinitis and bronchial asthma continues to increase. Allergens are the cause of these allergic diseases, and only 200 have been identified since they are currently identified. Pollen, a mite carcass, formaldehyde and the like are representative examples thereof, and these allergens enter the body in some form, causing various allergic symptoms.

In addition, similar to these allergic diseases, what threatens the health of people is a virus represented by an influenza virus or the like. A virus is a structure that contains DNA or RNA as a nucleic acid component and is parasitic to proliferate in living cells, and is infected by air infection or splash infection, and is particularly popular among people in winter when air is dry.

As a preventive measure of these allergic diseases and viral infections, wearing a disposable mask is the simplest and most effective. However, disposable masks only physically capture allergens or viruses, and active allergens or viruses remain in the mask. For this reason, there is a possibility that a large amount of active allergens and viruses enter the body by a certain shock, and the risk is high especially when the mask is taken off.

In connection with this, the invention regarding the mask which consists of fibers which have a substance which reduces the allergen captured by the mask, and the allergen reduction sheet for masks is disclosed (refer patent document 1). According to the invention disclosed in Patent Document 1, it is possible to provide a mask that exhibits a good allergen reduction effect as compared with a conventional mask.

Moreover, the invention regarding the antiviral mask which consists of an electret filter which adhered the extraction component of tea is disclosed (refer patent document 2). According to the invention disclosed in Patent Document 2, it is possible to provide a mask that exhibits a favorable virus reduction effect as compared with a conventional mask.

By the way, when a ear mask part is put into a tension state by wearing a conventional disposable mask, not only does it feel a pain in an ear, but also a feeling of frustration may be felt because a mouth part cover part is stretched to the left and right and adheres to a mouth and a nostril. Particularly in women, when wearing a mask, the lipstick is attached to the mask, so there are not many people who are uncomfortable with wearing the mask. The masks disclosed in Patent Document 1 and Patent Document 2 are no exception.

As a disposable mask which eliminated this unpleasant feeling, what is called a three-dimensional disposable mask of the shape in which the mouth-covering part bulged so that a space | interval is fully secured between the mouth-covering part which covers a mouth, and a mouth can be mentioned. This three-dimensional disposable mask not only has excellent moisturizing properties but also does not adhere to the corners of the mouth and the nostrils, so that it does not make the user feel uncomfortable such as stuffiness, and thus the usability is very good for the wearer.

However, since the mouth cover part of this three-dimensional disposable mask is formed by welding a sheet-like material so that it may become a bulged shape, it is exposed under high temperature at the time of manufacturing a mouth cover part. As a mask of the type manufactured by welding the ear hook portion to the mouth lid portion, the chance of exposure under high temperature is further increased. Specifically, heat of approximately 150 ° C. or more is applied to the mask.

For this reason, even if the allergen inactivating agent and virus inactivating agent which are weak to heat are generally added to what is called a three-dimensional disposable mask manufactured through a welding process, the effect cannot fully be exhibited. Therefore, disposable masks having an anti-allergen effect and / or an antiviral effect, and which have little or no discomfort such as a wearer's feeling, have not been developed until now, and providing such a mask is very beneficial for improving the health of people.

[Patent Document 2] Japanese Patent Application Laid-Open No. 2002-136615

The present invention has been made in view of the above problems, and an object of the present invention is to provide a disposable mask which has an anti-allergen effect and / or an antiviral effect and hardly feels unpleasant feelings such as stuffiness.

MEANS TO SOLVE THE PROBLEM As a result of earnestly researching in order to solve the said subject, the said subject can be solved by welding the sheet | seat-type material which added the cyclodextrin which included the allergen deactivator and / or the virus deactivator, and forms the mouth cover part. It has been found that the present invention has been completed. More specifically, the present invention provides the following.

(1) A disposable mask comprising at least a mouth covering portion covering at least the wearer's mouth when worn and a pair of ear hook portions extending from both sides of the mouth covering portion and covering both ears, wherein the ear hook portion is more elastic than the elasticity of the mouth lid portion. A disposable mask having high elasticity, wherein the mouth cover portion is formed by welding a breathable sheet-like material, and one or both of cyclodextrin containing an allergen deactivator and a virus deactivator are added to the breathable sheet-like material.

The mouth cover portion of the disposable mask (1) is formed by welding a sheet-like material having air permeability. A plurality of sheet-like materials having air permeability may be used, for example, two sheets of sheet-like materials having air permeability may be welded together. In addition, the ear hook portion has a higher elasticity than that of the mouth cover portion, and has a structure in which the mouth cover portion is hard to deform. For this reason, the mouth cover portion is not in close contact with the mouth or the nostrils and hardly feels unpleasant feelings such as stuffiness. In the mask of the type in which the mouth cover part is swelled so that a gap can be sufficiently secured between the mouth cover part and the mouth value of a wearer, it does not feel more uncomfortable. In addition, the disposable mask according to the present invention is characterized by welding a sheet-like material to which a cyclodextrin (hereinafter also referred to as a cyclodextrin in a clathrate state) containing an allergen deactivator and / or a virus deactivator is formed to form a mouth cover. do. That is, by incorporating an allergen deactivator and a virus deactivator into a cyclodextrin, even when exposed to high temperature when welding a mask, these deactivators do not denature or volatilize. For this reason, the antiallergen effect and / or antiviral effect can fully be exhibited, and the disposable mask which a wearer does not feel uncomfortable can be provided.

(2) The disposable mask according to (1), wherein the ear hook portion is formed by welding a sheet-like material having an ear hook opening on both sides of the mouth lid portion.

The ear hook portion of the disposable mask (2) is formed by welding a sheet-like material having an opening for ear hooks on both sides of the mouth lid portion. By forming the ear hook portion using a sheet-like material having a higher elasticity than the elasticity of the lid portion, the lid portion is less likely to be deformed. For this reason, even when an impact from the outside is applied, the mouth cover portion is not in close contact with the mouth and nostrils, and the wearer hardly feels unpleasant feelings such as stuffiness. When manufacturing a mask, a step of closely attaching the ear hook portion to the mouth cover portion is added, but since the allergen inactivating agent and the virus inactivating agent are enclosed in cyclodextrin, the anti-allergen effect and / or antiviral effect can be sufficiently exhibited. Can provide a mask.

(3) The disposable mask according to (1) or (2), wherein the allergen deactivator is at least one selected from the group consisting of olive extract, calcium chloride and lanthanum chloride.

The allergen inactivating agent used in the disposable mask of (3) can effectively suppress allergens by inactivating allergens. Specifically, at least one selected from the group consisting of olive extract, calcium chloride and lanthanum chloride is used. By adding these allergen inactivating agents to the cyclodextrin in a mask, it is possible to provide a disposable mask that inactivates allergens more effectively.

(4) The disposable mask according to any one of (1) to (3), wherein the virus inactivating agent is iodine and / or catechin.

The virus inactivating agent used for the disposable mask of (4) can inactivate a virus and effectively suppress virus infection. Specifically, iodine or catechin is used. By adding these virus inactivating agents to the cyclodextrin and adding them in the mask, a disposable mask which inactivates the virus more effectively can be provided.

(5) The disposable mask according to any one of (1) to (4), wherein cyclodextrin that does not form a clathrate compound is further added to the breathable sheet-like material.

The sheet-like material used for formation of the mouth cover part of the disposable mask of (5) is further to which cyclodextrin which does not form a clathrate compound is added. The term "cyclodextrin that does not form a clathrate compound" as used in the present invention means a so-called covalent cyclodextrin that is not limited to an allergen inactivating agent or a clathrate compound of a virus inactivating agent and does not form a clathrate compound with any substance. do. In the presence of a cyclodextrin that does not form this clathrate compound (hereinafter also referred to as a covalent cyclodextrin), the inactivating agent which has escaped from the clathrate is re-capped to the covalent cyclodextrin in the vicinity, thereby preventing the anti-allergen effect and Can also keep antiviral effects longer Furthermore, since an odor component is contained in the cyclodextrin of a common state, deodorant effect can also be anticipated.

(6) The disposable mask according to (5), wherein the content of the cyclodextrin that does not form the clathrate compound is greater than the content of the cyclodextrin in which the allergen deactivator and / or virus deactivator is entrapped.

In the disposable mask of (6), a larger amount of cyclodextrin in the common state is added than the cyclodextrin in the inclusion state. According to this disposable mask (6), the anti-allergen effect and / or antiviral effect can be maintained longer, and more excellent deodorizing effect can be expected.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings.

First Embodiment

[Overall configuration]

The disposable mask 10 which concerns on 1st Embodiment of this invention is shown in FIG. The disposable mask 100 comprises a mouth cover 12 covering at least the mouth of the wearer, and a pair of ear hooks 13 extending from both sides of the mouth cover 12 and covering both ears. The disposable mask 10 is symmetric with respect to the first welding line 14 located approximately at the center of the mouth covering part 12 as a center line, and the mouth covering part 12 is mutually oriented in the first welding line 14. It consists of a pair of sheet-like materials joined together. Ear hook portion 13 is made of a pair of left and right sheet-like material bonded to the mouth lid portion 12 in the second welding line 16 at the rear end of the mouth lid portion 12, the opening 18 for hooking ears Has The mouth cover portion 12 is swollen so as not to be in close contact with the wearer's mouth or nostril.

[Mouth cover 12]

The sheet-like material constituting the mouth lid portion 12 is breathable and has a lower elasticity than the sheet-like material constituting the earring portion 13. The mouth lid portion 12 is configured to have a stiffness of 40 mm or less in accordance with the ductility A method specified in JIS-L-1096 so as not to expand or dent due to the wearer's breath. Specifically, a nonwoven fabric such as a melt bond nonwoven fabric or a spunbond nonwoven fabric made of thermoplastic synthetic fibers, a woven fabric, a plastic net, a woven fabric made of natural fibers, or a laminated product thereof is used. In addition, to the sheet-like material constituting the mouth lid portion 12, cyclodextrins containing allergen inactivating agents and cyclodextrins containing viral inactivating agents are added, and cyclodextrins not containing these inactivating agents are added.

[Allergen deactivator]

The "allergen inactivating agent" used in the present invention is to reduce the activity of allergens causing allergy and to suppress allergic symptoms, and various "allergen inactivating agents" can be used. Specifically, olive extract, calcium chloride, lanthanum chloride and the like are used. In addition, the "olive extract" in this invention extracts the leaf and the fruit of plant olive with water or an organic solvent.

[Virus inactivating agent]

The "virus inactivating agent" used in the present invention is to reduce the activity of the virus to suppress virus infection, and various "virus inactivating agents" can be used. Specifically, iodine, catechin and the like are used.

[Cyclodextrin]

The "cyclodextrin" used in the present invention is a cyclic oligosaccharide obtained by acting a microbial enzyme on starch. Cyclodextrins have the important property of blowing various guests into the cavity to form clathrate compounds. The formation of this clathrate compound is thought to be achieved by the van der Waals forces of the guest and the host and by hydrogen bonding of the hydroxyl group of the guest and cyclodextrin. Since the characteristic of such cyclodextrin is expressed more by the presence of water, it can be said that use of a mask is preferable.

The number of glucose groups contained in one cyclodextrin molecule is called α-cyclodextrin, 6 are β-cyclodextrin, and 8 are called γ-cyclodextrin. Both cyclodextrins have an excellent deodorizing effect. In particular, γ-cyclodextrins having eight glucose groups have a strong inclusion force, and thus have an excellent deodorizing effect of bad breath. In the present invention, any one cyclodextrin is appropriately selected depending on matching with the allergen inactivating agent and the virus inactivating agent. For example, β-cyclodextrin is preferably used for inclusion of the virus inactivating agent iodine. When γ-cyclodextrin is used for inclusion of iodine, it is not preferable because the inclusion force is so strong that iodine cannot escape from the inclusion state. In addition, these cyclodextrins are not limited to single use but can also be used together.

Moreover, when using a cyclodextrin of a clathrate state and cyclodextrin of a co-state, it is preferable that these cyclodextrins are another type. This is because, when the same type of cyclodextrin is used, it is highly likely that the deactivating agent released from the inclusion state will leave the inclusion state again. For example, in the case of using β-cyclodextrin in which iodine, which is a virus inactivating agent, is used, by using α-cyclodextrin as a common cyclodextrin, the antiviral effect can be effectively expressed and maintained. Furthermore, the deodorant effect of bad breath can also be exhibited by using together the gamma-cyclodextrin of co-state. Specifically, 1 part by weight or more of the co-state α-cyclodextrin and the co-state γ-cyclodextrin are combined and used in combination with 1 part by weight of β-cyclodextrin incorporating iodine which is a virus inactivating agent. And the deodorizing effect can be effectively expressed and maintained.

In addition, a cyclodextrin of a clathrate state can be obtained by adding and mixing a common cyclodextrin to an allergen deactivator and a virus deactivator. The determination of the cyclodextrin of a clathrate state and the cyclodextrin of a common state can be confirmed by elemental analysis etc. using X-rays, for example.

Moreover, cyclodextrin can be melt | dissolved in alcohol solvents, such as ethanol and IPA (isopropyl alcohol) by methylation, and printing to a nonwoven fabric is attained when such a cyclodextrin is used. In this case, however, since resin must be mixed, it should be noted that the resin may cover the cyclodextrin or damage the texture of the nonwoven fabric.

[Earring part 13]

The sheet-like material constituting the ear hook portion 13 preferably has air permeability, and has a higher elasticity than the sheet-like material constituting the mouth lid portion 12. Specifically, a stretchable nonwoven fabric or the like obtained by heat-treating a web made of thermally stretchable composite fibers is used. In addition, the ear hook 13 may use a string-like material in addition to the sheet-like material.

[Manufacturing method]

First, the sheet-like material constituting the mouth lid portion 12 is immersed in a mixed aqueous solution to which an allergen deactivator, a virus deactivator and a cyclodextrin are added. By this immersion, the cyclodextrin in a clathrate state and the cyclodextrin in a covalent state are arrange | positioned uniformly throughout the sheet-like material. At the time of immersion, the liquid temperature of the mixed aqueous solution is preferably room temperature, and the flow rate of the nonwoven fabric is preferably about 30 m / min. Moreover, citric acid, polycarboxylic acid, oxalic acid, glyoxal, dialkyl carbonate, etc. can be used as a fixer of cyclodextrin. Among them, citric acid is preferably used from the viewpoint of safety. It is preferable that the addition amount of citric acid is 5 times or more by weight ratio with respect to iodine, for example in the case of the cyclodextrin which contained iodine as a virus inactivating agent. Subsequently, after immersion, the sheet-like material is welded to form the mouth lid portion 12. The mouth lid 12 is formed to swell, and finally, the disposable mask 10 can be obtained by welding a sheet-like material having an opening constituting the ear hook portion 13 to both sides of the mouth lid 12. .

<Variation example>

As a modified example of the disposable mask 10 which concerns on 1st Embodiment of this invention, the disposable mask formed by the side cover part bend | folding and heat-pressing one piece of thermoplastic sheet material in two is mentioned. It is the same as that of the disposable mask 10 except that the formation method of the mouth cover part differs. In the disposable mask according to this modification, a bulging mouth cover part is formed by hot pressing a sheet-like material to form a first welding line.

According to the present invention, it is possible to provide a disposable mask which has an anti-allergen effect and / or an antiviral effect and hardly feels unpleasant feelings such as stuffiness by the wearer.
