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 throughout the year 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. As a result, the space between the mask and the face is humidified, and moisture is supplied to the oral cavity, thereby 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, not only the warm steam generated from the heated water-containing body is released from the mask body to the face side, but also to the side opposite to the face. Therefore, there is a problem that the space between the mask and the face cannot be humidified well.

[0006] The present invention has been made to solve the above problems, and an object thereof is to provide a mask that can humidify well between the mask and the face.

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 includes at least a first layer on the face side into which the water-containing body is inserted and a second layer on the covering portion side, the first layer has moisture permeability, and the second layer is moisture impermeable.

[0008] In the mask of the present invention, it is preferable that a steam holding layer capable of holding steam is provided on the face side surface of the first layer.

[0009] In the mask of the present invention, it is preferable that the first layer and the second layer have heat insulation properties.

[0010] Also, in the mask of the present invention, it is preferable that the water-containing body is heated by being irradiated with microwaves.

Effects of the Invention

[0011] 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.

[0012] In addition, since the first layer on the face side of the accommodation part has moisture permeability and the second layer on the covering part side is moisture impermeable, the warm steam emitted from the water-containing body in the accommodation part permeates through the moisture-permeable first layer and is released to the face side of the wearer. However, the moisture-impermeable second layer serves as a barrier on the side opposite to the wearer's face, and the steam is not released. Therefore, since the warm steam emitted from the water-containing body can be supplied only to the face side of the wearer, humidification can be performed efficiently.

Modes for Carrying Out the Invention

[0014] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIGS. 1 and 2 show a mask 1 of the present 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 accommodation part 6 provided on the face side surface of the covering part 5. The water-containing body 3 is heated by being irradiated with microwaves, for example, in a microwave oven after being accommodated in the accommodation part 6 of the mask body 2. Thereby, warm steam is emitted from the water-containing body 3 when the mask 1 is worn.

[0015] In this embodiment, the covering portion 5 is rectangular in plan view. The covering portion 5 has an upper edge 50 that extends horizontally below the eyes of the wearer's face when the mask 1 is worn, a lower edge 51 that extends horizontally across the lower jaw (or submandibular region), and left and right side edges 52, 53 that connect the upper edge 50 and the lower edge 51. The size of the covering portion 5 is not particularly limited. For example, it may be a size such that the left and right side edges 52, 53 vertically bisect the cheeks and cover a part of the nose, mouth, lower jaw, and cheeks of the face.

[0016] Further, in this embodiment, the covering portion 5 is flat before the mask 1 is worn (when not in use). That is, the structure of the covering portion 5 of this embodiment is different from that of a three-dimensional type covering portion. Specifically, the side edges of two mask pieces are joined by heat fusion or the like, and when not in use, the two mask pieces are folded over by a folding portion that extends vertically in the horizontal center. Even when the two mask pieces are unfolded, they do not become flat, which is 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.

[0017] 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 produced by the spunbond method, meltblown method, thermal bonding method, or spunlace method can be preferably used. More preferably, a non-woven fabric produced by the spunbond method can be used from the viewpoints of touch and shape retention, and a non-woven fabric produced by the meltblown method can be used from the viewpoint of the cutting performance for pollen, viruses, etc. Considering the above points, a suitable layer structure of the covering portion 5 can be, for example, an SMS layer (a three-layer structure of spunbond-meltblown-spunbond). In addition, an S layer (a single layer of spunbond) or an SS layer (a two-layer structure of spunbond-spunbond) can also be preferably mentioned. When the covering portion 5 has a laminated structure, the covering portion 5 can be formed by joining the outer peripheral edges of the sheets of each layer with a predetermined width by a known method such as sewing, ultrasonic welding, or heat fusion.

[0018] As the fiber materials of the woven fabric and non-woven fabric constituting each layer of the covering part 5, known materials 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.

[0019] The covering part 5 has a structure that can be extended in the vertical direction. For example, at least one pleat 54 formed by at least two folds extending in the horizontal direction is provided in the covering part 5. By the expansion of 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 corresponding to the size of the wearer's face.

[0020] 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, and heat fusion. The material of the ear-hanging band 7 is not particularly limited, but it is preferably an elastic 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.

[0021] 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 in the covering part 5 and joining the sheets of each layer constituting the covering part 5 at its upper and lower positions by ultrasonic welding or the like.

[0022] Next, as shown in FIGS. 1 to 3, the accommodating portion 6 has a first layer 60 on the face side and a second layer 61 on the side of the covering portion 5, 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, an opening is formed in the upper part of the accommodating portion 6, and it is formed in a bag shape capable of inserting and holding the water-containing body 3 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 portion 6 from the upper opening.

[0023] The accommodating portion 6 is attached to the covering portion 5 by joining the first layer 60 on the face side to the face-side surface of the covering portion 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 located above the upper edge of the second layer 61 is joined to the face-side surface of the covering portion 5. Thereby, when the covering portion 5 is extended in the vertical direction by expanding the pleats 54, the accommodating portion 6 does not interfere, and since the accommodating portion 6 is not restricted by the covering portion 5 and it is easy to bring the water-containing body 3 close to the wearer's face due to the weight of the water-containing body 3, the steam emitted from the water-containing body 3 can be efficiently supplied to the nose and mouth.

[0024] Further, since the upper edge of the first layer 60 on the face side is joined to the face-side surface of the covering portion 5, the first layer 60 is interposed between the upper opening of the accommodating portion 6 and the wearer's face when the mask 1 is worn. Thereby, even if the warm steam emitted from the water-containing body 3 in the accommodating portion 6 is released from the upper opening of the accommodating portion 6, it is not released to the wearer's face side until it passes through the first layer 60, so that it is possible to prevent the steam from directly hitting the wearer's face.

[0025] In the present embodiment, the accommodating portion 6 is attached to the covering portion 5 at a position below the upper edge 50 of the covering portion 5. Since the upper edge 50 of the covering portion 5 extends horizontally below the eyes of the wearer's face when the mask 1 is worn, if the accommodating portion 6 is attached at the position of the upper edge 50 of the covering portion 5, the nose is covered by the water-containing body 3 in the accommodating portion 6. When the nose is covered by the water-containing body 3, it becomes difficult to breathe through the nose, and there is a risk that the water-containing body 3 hits the nose and the wearing feeling of the mask 1 deteriorates. Therefore, in the present embodiment, the accommodating portion 6 is attached to the covering portion 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 portion 5 so that the accommodating body 6 is disposed below the wearer's nose when the mask 1 is worn.

[0026] The size of the accommodating portion 6 may be any size that allows the water-containing body 3 to 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.

[0027] 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 steam (water molecules). For example, the moisture permeability is preferably 1000 g / m 2 / 24h or more, more preferably 2000 g / m 2 / 24h or more, and even more preferably 3000 g / m 2 / 24h or more. Thereby, the warm steam 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 to the property of completely not passing steam (water molecules), but also includes the property of slightly passing steam (water molecules). For example, the moisture permeability is preferably 350 g / m 2 / 24h or less, more preferably 300 g / m 2It is more preferably below 24 h. The warm steam emitted from the water-containing body 3 in the accommodating part 6 has the non-permeable second layer 61 as a barrier on the side opposite to the wearer's face, so that the steam is not released. In this way, by making the first layer 60 of the accommodating part 6 moisture-permeable and the second layer 61 non-moisture-permeable, the warm steam emitted from the water-containing body 3 can be supplied only to the wearer's face side, and humidification can be performed efficiently.

[0028] Further, both the first layer 60 and the second layer 61 of the accommodating part 6 have heat insulation properties. The accommodating part 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 part 6 decreases, the time for generating warm steam 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 part 6 are heat-insulating, whereby it is possible to prevent the temperature of the heated water-containing body 3 in the accommodating part 6 from rapidly decreasing. As a result, the time for warm steam to be emitted from the water-containing body 3 can be extended.

[0029] The first layer 60 of the accommodating part 6 having the moisture permeability and heat insulation properties described above 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 fiber batting. Examples of the fibers constituting the fiber batting include polyester fibers, polyolefin fibers, polyamide fibers, and acrylonitrile fibers.

[0030] The second layer 61 of the accommodating part 6 having the heat insulation properties and being non-moisture-permeable described above can be configured using, for example, a material obtained by covering the foamed resin sheet or the sheet-shaped fiber batting used for the first layer 60 described above with a non-moisture-permeable material.

[0031] In this embodiment, the accommodation part 6 is provided with a vapor retention layer 62 capable of retaining vapor on the face side of the first layer 60 on the face side. This vapor retention layer 62 allows a part of the vapor emitted from the water-containing body 3 in the accommodation part 6 and passing through the first layer 60 to pass through as it is and be released to the wearer's face side, and retains a part of the vapor, thereby increasing the humidity between the mask body 2 and the wearer's face when the mask 1 is worn. As a result, the humidifying effect is improved, and the space between the mask body 2 and the wearer's face can be effectively humidified.

[0032] The vapor retention layer 62 can be formed 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 produced by the spunbond method, the thermal bond method, the spunlace method, etc. can be used, but from the perspective of touch, non-woven fabrics produced by the thermal bond method and the spunlace method can be more preferably used, and non-woven fabrics produced by the spunlace method can be particularly preferably used. As the fiber material of the woven fabric and non-woven fabric constituting the vapor 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. Note that the vapor retention layer 62 is preferably formed by laminating a plurality (two sheets in this embodiment) of sheet-like fibers (for example, non-woven fabric) from the perspectives of vapor retention function and flexibility.

[0033] Next, the water-containing body 3 is impregnated with a water retention liquid mainly containing moisture, and can generate vapor by being heated, for example, by irradiation with microwaves in a microwave oven. As shown in FIGS. 1 to 4, when the mask 1 is worn, the water-containing body 3 is accommodated in the accommodation part 6 of the mask body 2 in a heated state to release vapor, humidify the space between the mask body 2 and the face, and supply moisture to the oral cavity.

[0034] 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. Also, from the viewpoint of the influence on the usability depending on the weight of the water-containing body 3 when in 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 vapor can be supplied to the oral cavity. Moreover, 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 vapor can be generated for a long time, and a good usability can be obtained.

[0035] 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 when the mask 1 is worn, the water-containing body 3 may not deform along the facial shape at 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.

[0036] 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.

[0037] 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 in the left-right direction of the water-containing body 3. Thereby, the water-containing body 3 can be easily bent 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.

[0038] 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, and may also be formed so as to extend vertically in the region between the upper edge and the lower edge of the water-containing body 3.

[0039] 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.

[0040] For example, when forming the water-containing body 3 with pulp, the ratio of pulp:heat-fusible fiber can be 60:40 to 80:20. The water-containing body 3 can have a single-layer or a multi-layer structure. However, 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 called the middle layer, and the layers composed of the pair of nonwoven fabrics are called 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 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 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 side is composed of hydrophobic fibers, and the surface on the opposite side is composed of hydrophilic fibers such as rayon. The pair of nonwoven fabrics described above, for example, has a basis weight of 20 g / m 2 or more and 50 g / m 2 or less is preferable.

[0041] 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, water-soluble thickeners such as xanthan gum, hydroxypropyl methylcellulose (HPMC), hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC), agar, guar gum, carrageenan, etc., fragrances such as eucalyptus and mint, and surfactants (nonionic surfactants, amphoteric surfactants, anionic surfactants) for solubilizing the fragrance can be appropriately used. Before wearing the mask 1, that is, before being housed in the housing portion 6, the water-containing body 3 is preferably housed in a bag made of an impermeable aluminum laminate film, an aluminum vapor-deposited PET film, a transparent (silica) vapor-deposited PET film, etc.

[0042] 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 housed in the housing 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, so that a sufficient amount of steam can be supplied immediately after wearing the mask 1.

[0043] Also, 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 released to the wearer's face side. However, on the side opposite to the wearer's face, the moisture-impermeable second layer 61 serves as a barrier and the steam is not released. Therefore, since the warm steam emitted from the water-containing body 3 can be supplied only to the wearer's face side, humidification can be performed efficiently.

[0044] Also, according to the mask 1 of the present embodiment, since a steam-retaining layer 62 capable of retaining steam is provided on the face side 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 retained by the steam-retaining layer 62. Therefore, due to the steam-retaining layer 62, the humidity between the mask body 2 and the wearer's face when the mask 1 is worn increases, so the humidifying effect is improved, and the space between the mask body 2 and the wearer's face can be effectively humidified.

[0045] Also, 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] Also, 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 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 wearer's face. Therefore, even if the warm steam emitted from the water-containing body 3 in the accommodating portion 6 is released from the upper opening of the accommodating portion 6, it is not released to the wearer's face side until it passes through the first layer 60, so it is possible to prevent the steam from directly hitting the wearer's face.

[0047] Further, according to the mask 1 of the present embodiment, the accommodating 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 accommodating body 6 is disposed below 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. Moreover, the water-containing body 3 does not hit the nose and the wearing feeling of the mask 1 does not deteriorate.

[0048] 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 can be made without departing from the spirit of the present invention.

[0049] For example, in the above embodiment, the water-containing body 3 is heated by being irradiated with microwaves after being accommodated in the accommodating portion 6 of the mask body 2. However, it may be accommodated in the accommodating portion 6 of the mask body 2 after being heated by being irradiated with microwaves.

[0050] Further, in the above embodiment, the water-containing body 3 is heated by being irradiated with microwaves, for example, in a microwave oven. However, the method of heating the water-containing body 3 is not particularly limited, and various methods may be used.

[0051] Moreover, a vapor retaining layer 62 is provided on the first layer 60 on the face side of the accommodating portion 6. However, this vapor retaining layer 62 is not necessarily provided.

[0052] Further, in the above embodiment, both the first layer 60 and the second layer 61 of the accommodating portion 6 have heat insulating properties. However, only one of them may have heat insulating properties, or neither of them may have heat insulating properties.

[0053] Further, in the above embodiment, the accommodating portion 6 is attached to the covering portion 5 at a position below the upper edge 50 of the covering portion 5. However, it may be attached to the covering portion 5 at the position of the upper edge 50 of the covering portion 5.

[0054] In the above-described embodiment, 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 covering portion 5. However, the upper edge of the second layer 61 on the covering portion 5 side may be located above the upper edge of the first layer 60 on the face side and be joined to the covering portion 5.

[0055] In the above-described embodiment, the water-containing body 3 has the ventilation holes 30 formed therein. However, the ventilation holes 30 do not necessarily have to be formed.

[0056] 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.
