Description

Technical Field

[0001] The present invention relates to a mask worn on the face, and more particularly to a mask that emits steam.

Background Art

[0002] Conventionally, masks have been widely used as a countermeasure against fine dust such as pollen and yellow sand, and also as a countermeasure against infections such as viruses and bacteria. Recently, the functions of masks have diversified, and various masks have been proposed. For example, during sleep, since there is no swallowing of food, drink, saliva, etc., the oral cavity is likely to become dry. Also, in winter, the air is generally dry, and even outside of winter, air conditioners are operating year-round in offices. Therefore, there are many environments where the air is likely to be dry even during the day, and the oral cavity is likely to become dry.

[0003] To prevent this, for example, Patent Document 1 discloses a mask having a humidifying function. The mask of Patent Document 1 accommodates a water-containing body containing moisture in a silicon bag-shaped mask body in which a large number of through holes are formed, and a filter containing moisture is accommodated in the mask body in a heated state, so that warm steam is generated. Thereby, the space between the mask and the face is humidified, and moisture is supplied to the oral cavity, thus preventing dryness of the oral cavity.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the mask of Patent Document 1, since the warm steam generated from the heated water-containing body directly hits the face, there is a risk of burning the nose or the like.

[0006] The present invention has been made to solve the above problems, and an object thereof is to provide a mask in which warm steam generated from a heated water-containing body does not directly hit the nose.

Means for Solving the Problems

[0007] The present invention relates to a mask that is worn on the face and emits steam. The mask of the present invention includes a mask body and a water-containing body containing moisture. The mask body includes a covering portion that covers a part of the wearer's face, and a bag-shaped accommodating portion provided on the face side surface of the covering portion for accommodating the heated water-containing body. The accommodating portion is attached to the covering portion at a position below the upper edge of the covering portion.

[0008] In the mask of the present invention, the accommodating portion includes at least a first layer on the face side and a second layer on the covering portion side into which the water-containing body is inserted therebetween. A part of the second layer except for the upper edge is joined to the first layer. The upper edge of the first layer is preferably located above the upper edge of the second layer and joined to the covering portion at a position below the upper edge of the covering portion.

[0009] Also, in the mask of the present invention, the water-containing body is preferably heated by being irradiated with microwaves.

Effects of the Invention

[0010] According to the present invention, when the mask is worn, warm steam is generated from the heated water-containing body, and thereby the space between the mask body and the wearer's face is humidified. Therefore, since moisture is supplied to the oral cavity, dryness of the oral cavity can be prevented.

[0011] Also, the accommodating portion is attached to the covering portion at a position below the upper edge of the covering portion. Therefore, when the mask is worn, the accommodating body is disposed below the wearer's nose, so that the nose is not covered by the water-containing body, and the wearer can easily breathe through the nose, and the water-containing body does not hit the nose to reduce the wearing feeling of the mask.

Mode for Carrying Out the Invention

[0013] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIGS. 1 and 2 show a mask 1 of this embodiment. The mask 1 includes a mask body 2 that covers a part of the wearer's face (the area below the eyes, particularly the nose and mouth), and a water-containing body 3 that contains moisture. The mask body 2 includes a covering part 5 that covers a part of the wearer's face when worn, and a bag-shaped housing part 6 provided on the face side surface of the covering part 5. After the water-containing body 3 is housed in the housing part 6 of the mask body 2, it is heated by being irradiated with microwaves, for example, in a microwave oven. Thereby, warm steam is emitted from the water-containing body 3 when the mask 1 is worn.

[0014] In this embodiment, the covering part 5 has a rectangular shape in plan view. The covering part 5 has an upper edge 50 that extends horizontally below the eyes of the wearer when the mask 1 is worn, a lower edge 51 that extends horizontally along the lower jaw (or submandibular region), and left and right side edges 52 and 53 that connect the upper edge 50 and the lower edge 51. The size of the covering part 5 is not particularly limited, and for example, it may be a size such that the left and right side edges 52 and 53 vertically cross the cheeks and cover a part of the nose, mouth, lower jaw, and cheeks of the face.

[0015] In addition, in this embodiment, the covering portion 5 is flat before wearing the mask 1 (when not in use). That is, the structure of the covering portion 5 in this embodiment is different from that of a three-dimensional type covering portion. Specifically, the side edges of the two mask pieces are joined by heat fusion or the like, and when not in use, the two mask pieces are folded on top of each other by a folding portion extending in the vertical direction at the center in the horizontal direction. Even when the two mask pieces are unfolded, they do not become flat, and are different from a structure that forms a large space between the lower part of the nose (nostrils) and the mouth when worn on the face. When worn on the face, it adheres more closely to the surface of the face than a three-dimensional type covering portion.

[0016] The covering portion 5 can have a single-layer structure or a laminated structure of two or more layers, and each layer can be configured using a breathable sheet such as a woven fabric or a non-woven fabric. Among them, non-woven fabrics obtained by the spunbond method, meltblown method, thermal bond method, or spunlace method can be preferably used. More preferably, from the viewpoints of touch and shape retention, a non-woven fabric obtained by the spunbond method can be used, and from the viewpoint of the cutting performance of pollen, viruses, etc., a non-woven fabric obtained by the meltblown method can be used. Considering the above points, as a preferable layer structure of the covering portion 5, for example, an SMS layer (a three-layer structure of spunbond-meltblown-spunbond) can be mentioned. In addition, an S layer (a single layer of spunbond) or an SS layer (a two-layer structure of spunbond-spunbond) can be preferably mentioned. When the covering portion 5 has a laminated structure, the outer peripheral edges of the sheets of each layer can be joined by a predetermined width by known methods such as sewing, ultrasonic welding, and heat fusion to form the covering portion 5.

[0017] As the fiber materials of the woven fabric and non-woven fabric constituting each layer of the covering portion 5, known ones can be used. For example, natural fibers such as paper and cotton; semi-synthetic fibers such as rayon and acetate; synthetic fibers such as polypropylene, polyethylene, polyester, and nylon can be used. Among them, polypropylene and polyethylene can be preferably used from the viewpoint of productivity, polypropylene can be used from the viewpoint of shape retention, and nylon can be used from the viewpoint of touch.

[0018] The covering part 5 has a structure that can be extended in the vertical direction. For example, the covering part 5 is provided with at least one pleat 54 formed by at least two folds extending in the horizontal direction. By expanding this pleat 54, the covering part 5 can be extended in the vertical direction, and the size of the covering part 5 can be freely adjusted according to the size of the wearer's face.

[0019] On the left and right side edges 52, 53 of the covering part 5, an ear-hanging band 7 is attached as holding means for holding the covering part 5 on the wearer's face. The ear-hanging band 7 can be attached to the covering part 5 by known methods such as sewing, ultrasonic welding, heat fusion, etc. The material of the ear-hanging band 7 is not particularly limited, but it is preferably a stretchable material such as polyester. In addition, as the holding means of the covering part 5, various other means other than the ear-hanging band 7 may be used.

[0020] At a position inside the upper edge 50 of the covering part 5, a linear nose piece 8 made of, for example, a plastic resin such as polyethylene or a biodegradable resin is provided. The nose piece 8 prevents a gap from occurring between the wearer's nose and the covering part 5, so that the covering part 5 can be fitted to the face. The nose piece 8 can be fixed at a predetermined position, for example, by being built into the covering part 5 and joining the sheets of each layer constituting the covering part 5 at its upper and lower positions by, for example, ultrasonic welding.

[0021] Next, as shown in FIGS. 1 to 3, the accommodating part 6 has a first layer 60 on the face side and a second layer 61 on the covering part 5 side, and a portion of the outer peripheral edge of the second layer 61 excluding the upper edge is joined to the first layer 60. Thereby, the accommodating part 6 is formed in a bag shape with an opening formed at the upper part, and the water-containing body 3 can be inserted and held between the first layer 60 and the second layer 61. In the present embodiment, the upper edge of the second layer 61 is located below the upper edge of the first layer 60, making it easier to insert the water-containing body 3 into the accommodating part 6 from the upper opening.

[0022] The accommodating part 6 is attached to the covering part 5 by joining the first layer 60 on the face side to the face side of the covering part 5 by a known method such as sewing, ultrasonic welding, or heat fusion. In the present embodiment, only the upper edge of the first layer 60, which is located above the upper edge of the second layer 61, is joined to the face side of the covering part 5. As a result, when the covering part 5 is extended in the vertical direction by expanding the pleats 54, the accommodating part 6 does not interfere, and since the accommodating part 6 is not restricted by the covering part 5 and the weight of the water-containing body 3 makes it easy to bring the water-containing body 3 closer to the face of the wearer, the steam emitted from the water-containing body 3 can be efficiently supplied to the nose and mouth.

[0023] Also, since the upper edge of the first layer 60 on the face side is joined to the face side of the covering part 5, the first layer 60 is interposed between the upper opening of the accommodating part 6 and the face of the wearer when the mask 1 is worn. As a result, even if the warm steam emitted from the water-containing body 3 in the accommodating part 6 is discharged from the upper opening of the accommodating part 6, it is not discharged to the face side of the wearer until it passes through the first layer 60, so it is possible to prevent the steam from directly hitting the face of the wearer.

[0024] In the present embodiment, the accommodating part 6 is attached to the covering part 5 at a position below the upper edge 50 of the covering part 5. Since the upper edge 50 of the covering part 5 extends horizontally below the eyes of the wearer when the mask 1 is worn, if the accommodating part 6 is attached at the position of the upper edge 50 of the covering part 5, the nose is covered by the water-containing body 3 in the accommodating part 6. When the nose is covered by the water-containing body 3, it becomes difficult to breathe through the nose, and there is a possibility that the wearing feeling of the mask 1 will deteriorate because the water-containing body 3 hits the nose. Therefore, in the present embodiment, the accommodating part 6 is attached to the covering part 5 at a position shifted downward by a predetermined height (for example, 15 mm or more and 30 mm or less) from the upper edge 50 of the covering part 5 so that the accommodating body 6 is disposed below the nose of the wearer when the mask 1 is worn.

[0025] The size of the accommodating part 6 may be such that the water-containing body 3 can be placed inside. For example, the length in the horizontal direction can be 50 mm or more and 150 mm or less, and the length in the vertical direction can be 30 mm or more and 80 mm or less.

[0026] The first layer 60 on the face side of the accommodating portion 6 has moisture permeability. This moisture permeability is the property of being able to pass through vapor (water molecules). For example, the moisture permeability is preferably 1000 g / m 2 / 24 h or more, more preferably 2000 g / m 2 / 24 h or more, and even more preferably 3000 g / m 2 / 24 h or more. Thereby, the warm vapor emitted from the water-containing body 3 in the accommodating portion 6 permeates through the first layer 60 and is released to the face side of the wearer. On the other hand, the second layer 61 on the covering portion 5 side of the accommodating portion 6 is moisture-impermeable. This moisture impermeability is not limited only to the property of not completely passing through vapor (water molecules), but also includes the property of slightly passing through vapor (water molecules). For example, the moisture permeability is preferably 350 g / m 2 / 24 h or less, and more preferably 300 g / m 2 / 24 h or less. The warm vapor emitted from the water-containing body 3 in the accommodating portion 6 is blocked by the moisture-impermeable second layer 61 on the side opposite to the face of the wearer and the vapor is not released. In this way, by making the first layer 60 of the accommodating portion 6 moisture-permeable and the second layer 61 moisture-impermeable, the warm vapor emitted from the water-containing body 3 can be supplied only to the face side of the wearer, and efficient humidification can be achieved.

[0027] Also, both the first layer 60 and the second layer 61 of the accommodating portion 6 have heat insulation properties. The accommodating portion 6 accommodates the water-containing body 3 after being heated by irradiation with microwaves using a microwave oven or the like. When the temperature of the heated water-containing body 3 in the accommodating portion 6 decreases, the time for generating warm vapor from the water-containing body 3 becomes shorter. Therefore, in the present embodiment, the first layer 60 and the second layer 61 of the accommodating portion 6 are made heat-insulating, whereby it is possible to prevent the temperature of the heated water-containing body 3 in the accommodating portion 6 from rapidly decreasing. As a result, the time for emitting warm vapor from the water-containing body 3 can be extended.

[0028] The first layer 60 of the accommodating portion 6 having the above-described moisture permeability and heat insulation properties can be configured using, for example, a foamed resin sheet made of foamed polyurethane, foamed polyolefin, foamed polyvinyl chloride (PVC), or the like, or a sheet-shaped fibrous batting. Examples of the fibers constituting the fibrous batting include polyester fibers, polyolefin fibers, polyamide fibers, and acrylonitrile fibers.

[0029] The second layer 61 of the accommodating portion 6 having the above-described heat insulation property and being moisture impermeable can be configured using, for example, a material obtained by covering the foamed resin sheet or the sheet-shaped fibrous batting used for the first layer 60 described above with a moisture impermeable material.

[0030] In this embodiment, the accommodating portion 6 is provided with a vapor retaining layer 62 capable of retaining vapor on the face side surface of the first layer 60 on the face side. The vapor retaining layer 62 allows a part of the vapor emitted from the water-containing body 3 in the accommodating portion 6 and permeating through the first layer 60 to pass through as it is and be released to the face side of the wearer, and retains a part of the vapor, thereby increasing the humidity between the mask body 2 and the face of the wearer when the mask 1 is worn. As a result, the humidifying effect is improved, and the space between the mask body 2 and the face of the wearer can be effectively humidified.

[0031] The steam retention layer 62 can be configured using breathable sheet-like fibers such as woven fabric or non-woven fabric, and among them, non-woven fabric can be preferably used. As the non-woven fabric, non-woven fabrics by the spunbond method, thermal bond method, spunlace method, etc. can be used, but from the perspective of touch, non-woven fabrics by the thermal bond method and spunlace method can be more preferably used, and non-woven fabrics by the spunlace method can be particularly preferably used. As the fiber material of the woven fabric and non-woven fabric constituting the steam retention layer 62, hydrophobic fibers can be preferably used from the perspective of preventing wetness and stickiness, and for example, synthetic fibers such as polypropylene, polyethylene, and polyester can be used. Among them, polypropylene and polyethylene can be preferably used from the perspectives of flexibility and productivity. Incidentally, the steam retention layer 62 is preferably formed by overlapping a plurality (two sheets in this embodiment) of sheet-like fibers (for example, non-woven fabric) from the perspectives of steam retention function and flexibility.

[0032] Next, the water-containing body 3 is impregnated with a water retention liquid mainly containing moisture, and can be heated by irradiation with microwaves, for example, in a microwave oven, to generate steam. As shown in FIGS. 1 to 4, when the mask 1 is worn, the water-containing body 3 is housed in the housing portion 6 of the mask body 2 in a heated state to release steam, humidify the space between the mask body 2 and the face, and supply moisture to the oral cavity.

[0033] The water-containing body 3 is not particularly limited, but preferably contains a large amount of water-retaining liquid. The amount of the water-retaining liquid contained in the water-containing body 3 (impregnation amount) is preferably 6 g or more, more preferably 12 g or more, and even more preferably 16 g or more. Further, from the viewpoint of the influence on the feeling of use due to the weight of the water-containing body 3 during use, the impregnation amount of the water-containing body 3 is preferably 30 g or less, more preferably 24 g or less, and even more preferably 20 g or less. Since the water-containing body 3 contains a large amount of water-retaining liquid, a large amount of steam can be supplied to the oral cavity. In addition, the water-containing body 3 is less likely to cool down after being heated, so the temperature of the water-containing body 3 that has become high due to heating can be maintained for a long time. Thus, when the mask 1 is worn, the heat retention time of the water-containing body 3 can be maintained for a long time, so that warm steam can be generated for a long time, and a good feeling of use can be obtained.

[0034] Also, in order to hold such an amount of water-retaining liquid, the basis weight of the water-containing body 3 is preferably 500 g / m 2 or more, and more preferably 800 g / m 2 or more. On the other hand, if the basis weight is too large, the water-containing body 3 becomes hard, so that when the mask 1 is worn, the water-containing body 3 may not deform along the facial shape of the wearer's mouth area, and the wearer may feel uncomfortable. Therefore, the basis weight of the water-containing body 3 is preferably 1500 g / m 2 or less, and more preferably 1000 g / m 2 or less.

[0035] In the present embodiment, the water-containing body 3 has a rectangular shape in plan view. Since the water-containing body 3 is used at the wearer's mouth area when the mask 1 is worn, its size is preferably, for example, 4 cm or more and 14 cm or less in the horizontal direction and 2 cm or more and 7 cm or less in the vertical direction, and more preferably 7 cm or more and 11 cm or less in the horizontal direction and 3 cm or more and 6 cm or less in the vertical direction. In terms of area, for example, it is preferably 8 cm 2 or more and 98 cm 2 or less, and more preferably 25 cm 2 or more and 50 cm 2 or less.

[0036] Since the water-containing body 3 covers the wearer's mouth when the mask 1 is worn, ventilation holes 30 are formed in the water-containing body 3 so as not to obstruct the wearer's breathing through the mouth. This facilitates the wearer's breathing through the mouth when the mask 1 is worn. The ventilation holes 30 may be composed of a plurality of small-diameter holes, or may be composed of one or more notches, but are preferably composed of notches extending in the vertical direction at the central position of the water-containing body 3 in the left-right direction. This makes it possible to easily bend the water-containing body 3 along the ventilation holes 30 at the central position in the left-right direction. In order to impregnate the water-containing body 3 with a large amount of moisture, as described above, it is necessary to increase the basis weight of the water-containing body 3. However, when the basis weight increases, the water-containing body 3 becomes hard, and when the mask 1 is worn, the water-containing body 3 may not conform to the facial shape around the wearer's mouth, so the wearer may feel uncomfortable. However, if the ventilation holes 30 make the water-containing body 3 easily bendable at the central position in the left-right direction, even if the basis weight of the water-containing body 3 is large, when the mask 1 is worn, the water-containing body 3 deforms along the facial shape around the wearer's mouth, so the wearer will not feel uncomfortable.

[0037] In addition, in this embodiment, the ventilation holes 30 are formed so as to extend upward from the lower edge of the water-containing body 3, but may be formed so as to extend downward from the upper edge of the water-containing body 3, or may be formed so as to extend downward and upward from the upper edge and the lower edge of the water-containing body 3, respectively, or may be formed so as to extend vertically in the region between the upper edge and the lower edge of the water-containing body 3.

[0038] The water-containing body 3 can be formed of various fiber materials, but can be formed of hydrophilic fibers or blended fibers of hydrophilic fibers and synthetic fibers. Examples of the fiber material include polyethylene, polypropylene, polyester, rayon, cotton, pulp, etc., and preferably pulp can be mentioned from the viewpoints of flexibility and water retention. The manufacturing method of such a water-containing body 3 is not particularly limited, but can be manufactured by an airlaid method or the like, and it is preferable to blend heat-fusible fibers such as polyethylene with pulp as the main component at a predetermined ratio from the viewpoints of productivity, processability, and durability.

[0039] For example, when the water-containing body 3 is formed of pulp, the ratio of pulp:heat-fusible fibers may be 60:40 to 80:20. The water-containing body 3 can have a single-layer or a multi-layer structure, but from the viewpoints of durability and water retention, it is preferably a three-layer structure in which a fiber material is sandwiched between a pair of nonwoven fabrics. At this time, the layer sandwiched between the pair of nonwoven fabrics is referred to as the middle layer, and the layers composed of the pair of nonwoven fabrics are referred to as the end layers. The nonwoven fabrics of the end layers may be of the same material or different materials. Examples of the materials of these nonwoven fabrics include hydrophilic fibers, hydrophobic fibers, synthetic fibers, or blended fibers of hydrophilic fibers and synthetic fibers. Examples of the hydrophilic fibers include rayon and cotton, and rayon is preferred. Making it hydrophilic has the advantage that moisture is easily absorbed by the pulp during production, facilitating production. Examples of the hydrophobic fibers include polyesters such as polyethylene, polypropylene, and polyethylene terephthalate, and polyethylene and polypropylene are preferred. Making it hydrophobic has the advantage that wetting and stickiness can be prevented. Therefore, it is preferable that the surface facing the wearer is composed of hydrophobic fibers and the surface on the opposite side is composed of hydrophilic fibers such as rayon. The above-mentioned pair of nonwoven fabrics, for example, has a basis weight of 20 g / m 2 or more and 50 g / m 2 or less is preferable.

[0040] The water-retaining liquid to be impregnated into the water-containing body 3 may be only water, but it is mainly composed of water and a polyol can be blended into the water. Examples of the polyol include glycerin, dipropylene glycol, 1,3-butylene glycol, propylene glycol, sorbitol, 1,2-pentanediol, 1,2-hexanediol, etc. Among them, glycerin is preferable in terms of safety. In addition to these, preservatives such as methyl paraben and phenoxyethanol, moisturizers such as hyaluronate and betaine, plant extracts, xanthan gum, hydroxypropyl methylcellulose (HPMC), hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC), agar, guar gum, carrageenan, etc. Water-soluble thickeners, fragrances such as eucalyptus and mint, and surfactants (nonionic surfactants, amphoteric surfactants, anionic surfactants) for solubilizing the fragrances can be appropriately used. The water-containing body 3 is preferably stored in a bag made of an impermeable aluminum laminate film, an aluminum vapor-deposited PET film, a transparent (silica) vapor-deposited PET film, etc. before wearing the mask 1, that is, before being stored in the storage portion 6.

[0041] According to the mask 1 of the above-described embodiment, for example, warm steam is generated from the heated water-containing body 3 after being irradiated with microwaves by a microwave oven or the like, and thereby the space between the mask body 2 and the wearer's face is humidified. Therefore, since moisture is supplied to the oral cavity, dryness of the oral cavity can be prevented. Further, since the water-containing body 3 is stored in the storage portion 6 of the mask body 2 in a heated state, steam is immediately generated immediately after wearing the mask 1, and it does not take time until the steam is generated. Therefore, a sufficient amount of steam can be supplied immediately after wearing the mask 1.

[0042] Further, according to the mask 1 of the present embodiment, the storage portion 6 is attached to the covering portion 5 at a position below the upper edge 50 of the covering portion 5. Therefore, when the mask 1 is worn, the storage body 6 is disposed under the wearer's nose, so that the nose is not covered by the water-containing body 3, and the wearer can easily breathe through the nose, and the water-containing body 3 does not hit the nose and the wearing feeling of the mask 1 does not decrease.

[0043] Further, according to the mask 1 of the present embodiment, since the upper edge of the first layer 60 on the face side of the accommodating portion 6 is located above the upper edge of the second layer 61 on the covering portion 5 side and is joined to the face side surface of the covering portion 5, when the mask 1 is worn, the first layer 60 is interposed between the upper opening of the accommodating portion 6 and the face of the wearer. Therefore, even if the warm steam emitted from the water-containing body 3 in the accommodating portion 6 is discharged from the upper opening of the accommodating portion 6, it is not discharged to the face side of the wearer unless it passes through the first layer 60. Thus, it is possible to prevent the steam from directly hitting the face of the wearer.

[0044] Further, according to the mask 1 of the present embodiment, since a steam holding layer 62 capable of holding steam is provided on the face side surface of the first layer 60 on the face side of the accommodating portion 6, a part of the steam emitted from the water-containing body 3 in the accommodating portion 6 and passing through the first layer 60 is held by the steam holding layer 62. Therefore, due to the steam holding layer 62, the humidity between the mask body 2 and the face of the wearer when the mask 1 is worn increases, so that the humidifying effect is improved, and the space between the mask body 2 and the face of the wearer can be effectively humidified.

[0045] Further, according to the mask 1 of the present embodiment, since the first layer 60 and the second layer 61 of the accommodating portion 6 have heat insulation properties, it is possible to prevent the temperature of the heated water-containing body 3 in the accommodating portion 6 from rapidly decreasing. Therefore, warm steam can be generated from the water-containing body 3 for a longer time.

[0046] Further, according to the mask 1 of the present embodiment, since the first layer 60 on the face side of the accommodating portion 6 has moisture permeability and the second layer 61 on the covering portion 5 side is moisture impermeable, the warm steam emitted from the water-containing body 3 in the accommodating portion 6 passes through the moisture-permeable first layer 60 and is discharged to the face side of the wearer, but the moisture-impermeable second layer 61 serves as a barrier on the side opposite to the face of the wearer and the steam is not discharged. Therefore, since the warm steam emitted from the water-containing body 3 can be supplied only to the face side of the wearer, efficient humidification can be achieved.

[0047] As described above, the embodiments of the present invention have been described. However, the present invention is not limited to the above embodiments, and various modifications are possible without departing from the spirit of the present invention.

[0048] For example, in the above embodiment, the water-containing body 3 is heated after being irradiated with microwaves after being housed in the housing portion 6 of the mask body 2, but it may be housed in the housing portion 6 of the mask body 2 after being irradiated with microwaves and heated.

[0049] Also, in the above embodiment, the water-containing body 3 is heated by being irradiated with microwaves, for example, in a microwave oven, but the method of heating the water-containing body 3 is not particularly limited, and various methods may be used.

[0050] Also, in the above embodiment, the vapor retention layer 62 is provided on the first layer 60 on the face side of the housing portion 6, but this vapor retention layer 62 does not necessarily have to be provided.

[0051] Also, in the above embodiment, both the first layer 60 and the second layer 61 of the housing portion 6 have heat insulation properties, but only one of them may have heat insulation properties, or neither of them may have heat insulation properties.

[0052] Also, in the above embodiment, the first layer 60 of the housing portion 6 is moisture-permeable and the second layer 61 is moisture-impermeable, but both may be moisture-permeable.

[0053] Also, in the above embodiment, the upper edge of the first layer 60 on the face side of the housing portion 6 is located above the upper edge of the second layer 61 on the cover portion 5 side and is joined to the cover portion 5, but the upper edge of the second layer 61 on the cover portion 5 side may be located above the upper edge of the first layer 60 on the face side and be joined to the cover portion 5.

[0054] Also, in the above embodiment, the water-containing body 3 has ventilation holes 30 formed therein, but the ventilation holes 30 do not necessarily have to be formed.

[0055] In the above-described embodiment, the upper edge 50, the lower edge 51, and the left and right side edges 52, 53 of the covering portion 5 are formed in a straight line.
