When the mask of the present invention is actually worn, the side corresponding to the upper side of the wearer's body is referred to as “upper”, and the side corresponding to the lower side is referred to as “lower”.

  FIG. 1 is a schematic view showing an example of the mask of the present invention. 1A is a plan view, and FIG. 1B is a perspective view. Each plan view in the attached drawings is viewed from the inside, and is illustrated so that the upper side of the mask is located on the upper side of the figure.

The mask 100 of the present invention is basically coupled to the body 10 that covers the lower part of the face including the wearer's nose and mouth, and to the left and right of the body 10, and the body 10 is fixed to the lower part of the wearer's face. Part 90.
The main body portion 10 includes a main seat portion 20, a lower pocket portion 40 that forms a space for accommodating a wearer's lower jaw provided at a lower portion of the main seat portion 20, and a wear provided at an upper portion of the main seat portion 20. And an upper pocket portion 50 that forms a space for accommodating a person's nose.

  The main sheet portion 20 is one of the preferred embodiments having a laminate in which an inner sheet, a pathogen inactivating layer, and an outer sheet are laminated in this order from the wearer side. As will be described later, the pathogen inactivating layer is preferably composed of a plurality of sheet-like materials.

The inner sheet is basically used in contact with the wearer when worn, but the present invention is not limited to this.
The material of the inner sheet is not particularly limited. For example, non-woven fabrics such as dry nonwoven fabrics, wet nonwoven fabrics, spun melt nonwoven fabrics, and spun lace nonwoven fabrics; synthetic fiber fabrics; knits can be used. Among them, a material having a low basis weight is preferable in that air permeability is excellent.
Among these, it is one of preferred embodiments that the inner surface sheet is porous. Specific examples of the porous material include a net-like, mesh-like or gauze-like nonwoven fabric; an opening film; a net, mesh or lace obtained by interweaving or knitting synthetic fiber filaments. When the inner sheet is porous, the contact area with the skin is reduced, and the wearer feels better.
It is also one of preferred embodiments that the inner surface sheet has a bowl-shaped uneven structure on the surface. In this aspect, since the contact area with the skin is reduced and the cushioning property is provided, a so-called “soft touch” feel can be obtained, and the wearer's wearing feeling is excellent.
Furthermore, it is one of the preferable embodiments that the inner sheet is a funnel-type opening film as proposed by the present inventor in Japanese Patent Laid-Open No. 2002-238946. In this aspect, there is an effect of distributing and rectifying the exhaled breath, and it becomes easy to efficiently use the entire surface of the laminate.

The material constituting the inner sheet may be hydrophilic or hydrophobic.
As a material constituting the inner sheet, a material subjected to antifouling treatment, antibacterial treatment, water repellent treatment, or the like can be used.
Since the material which comprises an inner surface sheet | seat may be ingested into a body from a wearer's mouth, it is preferable that it is a highly safe thing.
The material constituting the inner sheet is preferably a material that does not generate dust, fallen fiber waste or the like due to friction during use.
The material constituting the inner surface sheet is preferably a material that is in contact with the lips of the wearer and is less likely to be adhered or soiled by cosmetics such as body fat and lipstick.
It is preferable that the material constituting the inner surface sheet is a material in which pathogens and resident bacteria discharged from the wearer are difficult to propagate on the surface.

The inner surface sheet can also be disposed over the entire surface of the laminate, and for example, can be partially disposed such as disposed only on the portion of the laminate that is in contact with the periphery of the lip.
The inner sheet may be disposed simply on the pathogen inactivating layer, or the surface of the inner sheet and the surface of the pathogen inactivating layer may be joined and integrated.
In the case where the inner sheet and the pathogen inactivating layer are simply laminated, it is easy to separate the two and change the inner sheet. In this aspect, for example, when the mask of the present invention is used continuously for a long time, the inner sheet is replaced when removing the mask for meal, bathing, etc. An excellent wearing feeling of the used product can be obtained.

The material of the outer sheet is not particularly limited. For example, non-woven fabrics such as dry nonwoven fabrics, wet nonwoven fabrics, spun melt nonwoven fabrics, and spun lace nonwoven fabrics; synthetic fiber fabrics; knits can be used. Among these, those having a dense structure and having relatively fine constituent fiber fineness capture the splashes when the wearer's breath is discharged to the outside, and also when the wearer inhales the outside air It is preferable because it captures dust and the like.
Among these, spun melt nonwoven fabrics of synthetic fibers such as PE, PP, PET, EVA, PE / PP composite fibers, and PE / PET composite fibers are preferable, and SMS and SMMS that are melt blown multilayers are more preferable.

The material constituting the outer sheet may be hydrophilic or hydrophobic.
As a material constituting the outer sheet, a material subjected to antifouling treatment, antibacterial treatment, water repellent treatment, or the like can be used.
The material constituting the outer sheet preferably has a smooth surface so that even if the mask of the present invention is attached / detached, even if the surface is touched by hand, the surface is not easily soiled.
The material constituting the outer sheet is preferably a material that does not generate dust, fluff, etc. due to friction during use.

The outer sheet can be disposed over the entire surface of the laminate, or can be partially disposed.
The outer sheet may be simply laminated under the pathogen inactivating layer, or the surface of the outer sheet and the surface of the pathogen inactivating layer may be joined and integrated.

A pathogen inactivation layer is a layer for inactivating a pathogen.
In the present invention, the pathogen is a general term for microorganisms, viruses and the like that cause respiratory diseases such as tuberculosis, influenza, pneumonia, bronchitis, and pharyngitis. Specific examples include bacteria, molds, rickettsias, mites, and viruses.
In the present invention, inactivation means detoxification, detoxification, neutralization, etc. of the pathogen. Specific examples of inactivation include filtration removal, adsorption removal, heat denaturation, chemical denaturation, and antibody reaction.

The pathogen inactivation layer is not particularly limited in configuration as long as it has a function to inactivate pathogens, but is preferably composed of one or more sheet-like materials, and a plurality of sheet-like materials. More preferably, it is comprised.
In this case, it is one of preferred embodiments that at least one of the plurality of sheet-like materials constituting the pathogen inactivating layer is folded. In this aspect, the folding ratio obtained by dividing the area before folding of the folded sheet-like material by the area in the folded state is preferably 1.5 or more, and 2.0 or more. It is more preferable that

  The laminated body preferably has a higher air permeability than both the lower pocket portion 40 and the upper pocket portion 50. In this case, since exhaled air easily passes through the laminate, it is difficult for exhaled air to leak.

The lower pocket part 40 is provided in the lower part of the main seat part 20, and forms the space which accommodates a wearer's lower jaw.
The lower pocket portion 40 is formed of a stretchable material.
Examples of the stretchable material include the following three stretchable materials.

(1) Stretch knitted fabrics, woven fabrics, and polyurethane filament spunbonded nonwoven fabrics obtained by knitting elastic yarns such as rubber yarns and polyurethane filaments or interweaving with other synthetic filaments and spun yarns. For example, a net-like material such as a night cap, an elastic bandage, an elastic supporter, pantyhose, or a structure having a structure used as a sock stopper can be used.

(2) Elastic films such as polyurethane film, EVA film, SEBS, SBR film.

(3) A composite sheet of an elastic filament or stretchable film and a nonwoven fabric. The elastic body is obtained by bonding the elastic body to the nonwoven fabric with a bonding agent in the stretched state, or sandwiching both surfaces of the stretchable films with the nonwoven fabric. For example, a compressor (registered trademark, Nippon Absorbent Technology Laboratory Co., Ltd.), Flex Air ^™ Elastic Laminate (Toledogar, USA), which is a unidirectional stretch composite in which an easily stretchable nonwoven fabric and a stretch film are laminated in the transverse direction. For example).

  The stretchable material used in the present invention preferably has a so-called easy-to-extend property that easily stretches under low stress. Specifically, it is preferable that the maximum extension rate (the ratio of the maximum length that can be reversibly extended with respect to the length when not extended) is 150% or more.

The lower pocket part 40 is provided in the lower part of the main seat part 20 so that the space which accommodates a wearer's lower jaw may be formed.
Specifically, a pocket-shaped space can be formed by combining the stretchable material constituting the lower pocket portion 40 and the main sheet portion 20.
The bonding method is not particularly limited, and examples thereof include hot melt, pressure-sensitive adhesive, ultrasonic seal, and heat seal.
By binding the stretchable material to the main sheet portion 20 in this way, the lower pocket portion 40 always adheres to the wearer's skin and follows the movement of the face, while the main sheet portion 20 is attached to the wearer's face. On the other hand, it can always be held at a fixed position.

The upper pocket part 50 is provided in the upper part of the main seat part 20, and forms the space which accommodates a wearer's nose.
The stretchable material used for the upper pocket portion 50 is the same as the stretchable material used for the lower pocket portion 40 described above.

The upper pocket part 50 is provided in the upper part of the main seat part 20 so that the space which accommodates a wearer's nose may be formed. As long as the space accommodates a portion around the nostril of the wearer's nose, it may accommodate a part of the nose or may accommodate the entire nose.
Specifically, a pocket-shaped space can be formed by combining the stretchable material constituting the upper pocket portion 50 and the main sheet portion 20.
The bonding method is not particularly limited, and examples thereof include hot melt, pressure-sensitive adhesive, ultrasonic seal, and heat seal.
By binding the stretchable material to the main sheet portion 20 in this way, the upper pocket portion 50 always adheres to the wearer's skin and follows the movement of the face, while the main sheet portion 20 is attached to the wearer's face. On the other hand, it can always be held at a fixed position.

  In the mask 100 of the present invention, the main body portion 10 may have a member other than the main sheet portion 20, the lower pocket portion 40, and the upper pocket portion 50.

The fixing portion 90 is coupled to the left and right of the main body portion 10 and fixes the main body portion 10 to the lower part of the wearer's face.
The fixing part 90 is formed of a stretchable material. The stretchable material used for the fixing portion 90 is the same as the stretchable material used for the lower pocket portion 40 described above.

  The stretchable materials forming the lower pocket portion 40, the upper pocket portion 50, and the fixing portion 90 may be the same or different.

  In the mask 100 of the present invention, as described above, the lower pocket portion 40, the upper pocket portion 50, and the fixing portion 90 are all formed of a stretchable material. This makes it difficult for exhalation to leak and makes it difficult for the main body of the mask to be displaced from the face. Furthermore, the wearer's ears and face are not strongly pressed.

The mask 100 of the present invention can be obtained by integrating (joining) the various members described above. The integration method is not particularly limited, and examples thereof include stitching with a sewing thread or the like; adhesion by hot melt or the like; welding by heat sealing, ultrasonic sealing, or the like. In the case of stitching with a perforated thread, the perforation can be sealed with a resin, an adhesive tape, or the like.
The mask 100 of the present invention is joined to a stretchable sheet member made of a stretchable material at the peripheral edges of the four sides of the main sheet portion 20 (dark hatched portion. Hereinafter, the joined portions are also shown in other drawings. (It may be indicated by a dark hatched part.)

  The mask 100 of the present invention is closely attached to the wearer's nose and the part corresponding to the lower jaw and the fixing part 90, and is fixed to the wearer's face. It is a preferable aspect of the mask of the present invention that the wearer's nose and the part corresponding to the lower jaw and the fixing part 90 are closely attached and fixed to the wearer's face.

  The mask 100 of the present invention accommodates the wearer's lower jaw in a space formed in the main body portion 10 between the main seat portion 20 and the lower pocket portion 40 provided in the lower portion of the main seat portion 20 when worn. And a wearer's nose is accommodated and used in the space formed between the main seat part 20 and the upper pocket part 50 provided in the upper part of the main seat part 20. For this reason, the lower edge of the main seat part 20 contacts over the vicinity of the wearer's jaw line, and the upper edge of the main seat part 20 contacts from the tip of the wearer's nose to the cheeks on both sides. And since the main seat part 20 exists between the lower edge and upper edge of these main seat parts 20, a space is formed between the main seat part 20 in the circumference of a wearer's mouth, and a wearer's The main sheet portion 20 is less likely to contact the periphery of the mouth.

  As shown in FIG. 1B, the mask 100 of the present invention has a main body 10 in which the lengths of the opening edges of the lower pocket portion 40 and the upper pocket portion 50 in the left-right direction correspond thereto. Since it is equal to the length of the sheet part 20 in the left-right direction, it has a planar structure from the main body part 10 to the fixed part 90, but the mask of the present invention is not limited to this.

A larger space is formed between the main seat portion and the periphery of the wearer's mouth.

In order to obtain a floating structure in which such a main seat portion is separated from the circumference of the wearer's mouth, for example, the length in the left-right direction of the opening edge of the lower pocket portion and / or the upper pocket portion is set as the main length. This can be realized by making the length of the portion corresponding to the seat portion shorter than the length in the left-right direction.
As shown in FIG. 2, the mask 106 according to the present invention has the left and right lengths of the opening edge portions of the lower pocket portion 46 and the upper pocket portion 56 in the left and right portions of the portion corresponding to the main sheet portion 26. It is shorter than the length.
In order to obtain such a structure, specifically, for example, when the lower pocket portion 46 and the upper pocket portion 56 are provided in the main seat portion 26, the stretchability that forms the lower pocket portion 46 and the upper pocket portion 56 is provided. It is possible to use a method of joining the main sheet portion 26 in a state where the material is pulled in the left-right direction and stretched to some extent and removing the pulling force after joining.
Such a structure is further formed by joining the main seat portion 26, the lower pocket portion 46, and the upper pocket portion 56 so as to be folded back when worn (see FIGS. 17D and 17E). ), It becomes easy to ensure a separated state between the main seat portion 26 and the face of the wearer.

2. Mask Evaluation Three adult subjects (two women and one man) were allowed to wear the masks obtained in Examples 1 and 2 and the masks of Comparative Examples 1 to 3 described later, and the following (1) to ( The items of 4) were evaluated.
FIG. 14 is a schematic perspective view of the mask of Comparative Example 1. The mask 110 shown in FIG. 14 was a gauze mask flat type (manufactured by White Cross Co., Ltd., gauze mask). Specifically, it was a gauze mask having fixed portions made of rubber strings on both the left and right sides of a main body portion formed by overlapping planar gauze.
FIG. 15 is a schematic perspective view of the mask of Comparative Example 2. The mask 112 shown in FIG. 15 was a pleat type gauze mask (manufactured by Kowa Co., Ltd., three-dimensional mask). Specifically, the gauze mask has fixing portions made of rubber strings on both left and right sides of a main body portion made of a single gauze provided with a plurality of pleats in the left-right direction.
FIG. 16 is a schematic perspective view of a mask of Comparative Example 3. The mask 114 shown in FIG. 16 was a three-dimensional mask (Unicharm, super solid mask). Specifically, the mask has a three-dimensional structure in which the main body is convex outward at the center in the left-right direction.

(1) Generation | occurrence | production state of the clearance gap at the time of wear As an index | exponent of the leak of the expiration | expired_air at the time of wear, the generation | occurrence | production state of the clearance gap at the time of wear was evaluated. Specifically, when the mask was worn, the state of occurrence of a gap with the wearer's face was evaluated on the four sides of the main body of the mask.
(2) Ease of slippage during wearing When wearing a mask, the wearer opened and closed the mouth up and down, and evaluated the ease of slippage of the mask at that time.
(3) Contact state to lips at the time of wearing When wearing a mask, the wearer moved the mouth and evaluated the contact state to the lips at that time.
(4) Contact state to cheek site at the time of wearing, feeling of pressure When wearing a mask, the contact state and feeling of pressure between the peripheral part of the body of the mask and the cheek were evaluated.

A summary of the results is shown in Table 1.
Moreover, the schematic diagram of the wearing condition of various masks is shown in FIG. 17A is a schematic diagram of the wearing state of the mask 110 of Comparative Example 1, FIG. 17B is a schematic diagram of the wearing state of the mask 112 of Comparative Example 2, and FIG. 17C is a comparative example. FIG. 17D is a schematic diagram of the wearing state of the mask 100 of Example 1, and FIG. 17E is the wearing state of the mask 106 of Example 2. It is a schematic diagram. As shown in FIGS. 17D and 17E, the mask 100 of Example 1 and the mask 106 of Example 2 are formed of stretchable sheet members (hatched portions in the figure). It was worn with the lower and upper pockets turned.

The mask of Comparative Example 1 had a poor wearing feeling because almost the entire inner surface of the main body was in contact with the periphery of the mouth, and in the case of a female wearer, lipstick was attached to the inner surface of the main body. In addition, the main body was displaced in conjunction with the movement of the mouth, and a large gap was generated at the periphery of the main body.
Since the pleat at the center of the mask spreads up and down, the mask of Comparative Example 2 can wrap the wearer's nose and lower chin to some extent. Although the body part swelled back and forth and became dented, it became easier for the recessed part to come into contact with the lips and cheeks of the wearer. It was attached. In addition, the center floated at the left and right ends of the main body, and a large gap was generated.
In the mask of Comparative Example 3, since the center of the main body is swollen, contact with the lips does not occur, and no lipstick adheres even in the case of a female wearer, but it is fixed at a position near the mouth of the cheek. Since it was combined with the upper part sheet, the feeling of pressure on both cheeks was felt somewhat stronger while wearing. Further, since the rigidity of the main body portion and the central seal portion is high, the mask is easily displaced up and down with the movement of the jaw.

In the mask of Example 1, the contact between the main body portion and the face only occurs at the portion of the elastic sheet member that forms the lower pocket portion and the upper pocket portion, and the main sheet portion floated from the mouth to the cheek. Since it was in a state (floating state), it was not in direct contact with the face, and no lipstick was attached even in the case of a female wearer.
In addition, with respect to facial movements such as opening and closing of the mouth, the flexible stretchable sheet absorbs the movements and is not transmitted to the main sheet part, so that there was almost no displacement of the main sheet part.
The mask of Example 2 has almost the same result as that of the mask of Example 1, but because the stretchable sheet member is stretched and joined to the main sheet part, the floating state of the main sheet part becomes large. The distance from the lips and the periphery of the mouth increased, and a comfortable wearing feeling was obtained. No lipstick was found even for female wearers.
