Description

[Technical Field]

[0001] The present invention relates to a face mask, and more particularly to a steam mask. [Background technology]

[0002] Masks have traditionally been widely used as a defense against fine dust particles such as pollen and yellow sand, and as a countermeasure against infections such as viruses and bacteria. Recently, mask functions have become more diverse, and a variety of masks have been proposed. For example, during sleep, the mouth can easily become dry because food, drink, and saliva are not swallowed. Furthermore, the air is generally dry in winter, and air conditioners are running year-round in offices even outside of winter. Therefore, many environments tend to have dry air even during the day, making the mouth more susceptible to dryness.

[0003] To prevent this, for example, Patent Document 1 discloses a mask with a humidifying function. The mask in Patent Document 1 has a mask body that covers the nose and mouth, and is equipped with a moisture-containing body and a heating element such as a hand warmer that fits closely to the moisture-containing body. The moisture-containing body is heated by the heating element to generate warm steam, which humidifies the space between the mask and the face and replenishes moisture in the oral cavity, preventing dryness of the oral cavity. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2000-225205 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the mask in Patent Document 1 uses a hand warmer to warm the water-containing body, which takes time for the hand warmer to generate heat. Also, because the water-containing body is heated indirectly, it takes time for steam to be generated immediately after putting on the mask, and the amount of steam produced immediately after putting on the mask is insufficient.

[0006] The present invention has been made to solve the above problems, and has an object to provide a mask that can supply a sufficient amount of steam immediately after wearing. [Means for solving the problem]

[0007] The present invention relates to a mask that is worn on the face and emits steam. The mask of the present invention comprises a mask body that covers part of the wearer's face, and a water-containing body that contains water and is heated by microwave irradiation to emit steam, and the mask body has a storage section that stores the heated water-containing body.

[0008] In the mask of the present invention, the mask body comprises a covering portion that covers part of the wearer's face, and a bag-shaped storage portion provided on the face-side surface of the covering portion, and the storage portion comprises at least a first layer on the face side and a second layer on the covering portion side between which the water-containing body is inserted, and it is preferable that the first layer is moisture-permeable and a vapor-retaining layer capable of retaining vapor is provided on the face-side surface of the first layer.

[0009] In the mask of the present invention, the first layer and the second layer preferably have heat insulating properties.

[0010] In the mask of the present invention, the second layer is preferably non-moisture permeable. [Effects of the Invention]

[0011] According to the present invention, when wearing a mask, the water-containing body is heated by microwave irradiation, for example, in a microwave oven, and then generates warm steam, which humidifies the space between the mask body and the wearer's face. This replenishes moisture in the oral cavity, preventing dryness of the oral cavity.

[0012] Furthermore, since the water-containing body is stored in the storage section in a heated state, it generates warm steam instantly, and it does not take long for steam to be generated immediately after putting on the mask, so a sufficient amount of steam can be supplied immediately after putting on the mask. [Brief explanation of the drawings]

[Figure 3] FIG. 2A is a rear view of the housing part, FIG. 2B is a front view, and FIG. 2C is a schematic cross-sectional view taken along the line X2-X2. [Figure 4] (A) is a front view of the water-containing body, and (B) is a side view. DETAILED DESCRIPTION OF THE INVENTION

[0014] An embodiment of the present invention will be described below with reference to the accompanying drawings. FIGS. 1 and 2 show a mask 1 of this embodiment. The mask 1 comprises a mask body 2 that covers part of the wearer's face (the area under the eyes, particularly the nose and mouth), and a water-containing body 3 that contains water. The mask body 2 comprises a covering portion 5 that covers part of the wearer's face when worn, and a bag-shaped storage portion 6 provided on the face-facing surface of the covering portion 5. The water-containing body 3 is stored in the storage portion 6 of the mask body 2 and then heated by exposure to microwaves, for example, in a microwave oven. As a result, warm steam is emitted from the water-containing body 3 when the mask 1 is worn.

[0015] In this embodiment, the covering portion 5 has a rectangular shape in a plan view. When the mask 1 is worn, the covering portion 5 has an upper edge 50 extending horizontally below the eyes of the wearer's face, a lower edge 51 extending horizontally across the chin (or below the chin), and left and right side edges 52, 53 connecting the upper edge 50 and the lower edge 51. The size of the covering portion 5 is not particularly limited, and may be any size as long as the left and right side edges 52, 53 extend vertically across the cheeks to cover the nose, mouth, chin, and part of the cheeks.

[0016] Furthermore, in this embodiment, the covering portion 5 is flat before the mask 1 is worn (when unused). That is, the covering portion 5 of this embodiment has a different structure from a three-dimensional covering portion. Specifically, the side edges of two mask pieces are joined together by heat fusion or the like, and when not in use, the two mask pieces are folded over each other by a folding portion that extends vertically in the center of the horizontal direction, and the two mask pieces do not become flat even when unfolded, and is different from a structure that forms a large space between the under-nose (nostrils) and the mouth when worn on the face, and when worn on the face, it fits more closely to the surface of the face than a three-dimensional 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 formed using a breathable sheet such as a woven fabric or nonwoven fabric. Among these, nonwoven fabrics made by the spunbond method, meltblown method, thermalbond method, or spunlace method are preferably used. More preferably, nonwoven fabrics made by the spunbond method are used from the viewpoint of texture and shape retention, and nonwoven fabrics made by the meltblown method are used from the viewpoint of performance in cutting pollen, viruses, etc. Taking the above points into consideration, a suitable layer structure for the covering portion 5 can be, for example, an SMS layer (a three-layer structure of spunbond-meltblown-spunbond). Other preferred examples include an S layer (a single-layer spunbond) or an SS layer (a two-layer structure of spunbond-spunbond). When the covering portion 5 has a laminated structure, the covering portion 5 can be formed by joining the outer edges of each layer of sheet to a predetermined width using a known method such as sewing, ultrasonic welding, or heat fusion.

[0018] Known fiber materials can be used for the woven and nonwoven fabrics constituting each layer of the covering portion 5, including natural fibers such as paper and cotton, semi-synthetic fibers such as rayon and acetate, and synthetic fibers such as polypropylene, polyethylene, polyester, and nylon. Among these, polypropylene and polyethylene are preferred from the viewpoint of productivity, polypropylene can be used from the viewpoint of shape retention, and nylon can be used from the viewpoint of feel.

[0019] The covering part 5 has a structure that is stretchable in the vertical direction. For example, the covering part 5 has 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 is stretchable in the vertical direction, and the size of the covering part 5 can be freely adjusted to correspond to the size of the wearer's face.

[0020] Ear bands 7 are attached to the left and right side edges 52, 53 of the covering part 5 as a means for holding the covering part 5 on the wearer's face. The ear bands 7 can be attached to the covering part 5 by a known method such as sewing, ultrasonic welding, or heat fusion. The material of the ear bands 7 is not particularly limited, but a stretchy material such as polyester is preferable. Note that various means other than the ear bands 7 may be used to hold the covering part 5.

[0021] A linear nose piece 8 made of, for example, a plastic resin such as polyethylene or a biodegradable resin is provided at a position inside the upper edge 50 of the covering part 5. The nose piece 8 prevents a gap from forming between the wearer's nose and the covering part 5, allowing the covering part 5 to fit the face. The nose piece 8 can be built into the covering part 5, for example, and fixed in place by joining the sheets of each layer that make up the covering part 5 at its upper and lower positions using, for example, ultrasonic welding.

[0022] Next, as shown in Figs. 1 to 3, the storage part 6 has a first layer 60 on the face side and a second layer 61 on the cover part 5 side, and the outer periphery of the second layer 61 is joined to the first layer 60 except for the upper edge. As a result, the storage part 6 is formed in a bag shape with an opening formed at the top, into which the water-containing body 3 can be inserted and held between the first layer 60 and the second layer 61. In this embodiment, the upper edge of the second layer 61 of the storage part 6 is located lower than the upper edge of the first layer 60, making it easy to insert the water-containing body 3 into the storage part 6 from the upper opening.

[0023] The storage section 6 is attached to the covering section 5 by joining the face-side first layer 60 to the face-side surface of the covering section 5 by a known method such as sewing, ultrasonic welding, or heat sealing. In this embodiment, only the upper edge of the first layer 60 of the storage section 6, which is located above the upper edge of the second layer 61, is joined to the face-side surface of the covering section 5. This means that the storage section 6 does not interfere with the longitudinal extension of the covering section 5 by expanding the pleats 54, and furthermore, since the storage section 6 is not constrained by the covering section 5 and the weight of the water-containing body 3 makes it easier to bring the water-containing body 3 close to the wearer's face, steam emitted from the water-containing body 3 can be efficiently supplied to the nose and mouth.

[0024] Furthermore, because the upper edge of the first layer 60 on the face side is joined to the face side surface of the covering part 5, the first layer 60 is interposed between the upper opening of the storage part 6 and the wearer's face when the mask 1 is worn. As a result, even if warm steam emitted from the water-containing body 3 in the storage part 6 is released from the upper opening of the storage part 6, it is not released towards the wearer's face until it has passed through the first layer 60, and therefore it is possible to prevent the steam from directly hitting the wearer's face.

[0025] In this embodiment, the storage section 6 is attached to the covering section 5 at a position lower than the upper edge 50 of the covering section 5. Since the upper edge 50 of the covering section 5 extends horizontally below the eyes of the wearer when the mask 1 is worn, if the storage section 6 is attached to the position of the upper edge 50 of the covering section 5, the nose will be covered by the water-containing body 3 in the storage section 6. If the nose is covered by the water-containing body 3, it will be difficult to breathe through the nose, and the water-containing body 3 may come into contact with the nose, reducing the comfort of wearing the mask 1. Therefore, in this embodiment, the storage section 6 is attached to the covering section 5 at a position that is shifted downward by a predetermined height (for example, 15 mm to 30 mm) from the upper edge 50 of the covering section 5 so that the storage section 6 is positioned below the wearer's nose when the mask 1 is worn.

[0026] The size of the storage section 6 need only be large enough to accommodate the water-containing body 3 inside, and for example, the horizontal length can be 50 mm or more and 150 mm or less, and the vertical length can be 30 mm or more and 80 mm or less.

[0027] The first layer 60 on the face side of the housing part 6 has moisture permeability. This moisture permeability is a property that allows vapor (water molecules) to pass through. For example, the moisture permeability is 1000 g / m 2 / 24h or more is preferable, and 2000g / m 2 / 24h or more is more preferable, and 3000g / m 2 / 24h or more is more preferable. This allows the warm steam emitted from the water-containing body 3 in the storage section 6 to pass through the first layer 60 and be released to the wearer's face side. On the other hand, the second layer 61 on the cover section 5 side of the storage section 6 is moisture-impermeable. This moisture-impermeable property is not limited to a property that completely blocks moisture (water molecules), but also includes a property that allows a small amount of moisture (water molecules) to pass through. For example, if the moisture permeability is 350g / m 2 / 24h or less is preferable, and 300g / m 2 / 24h or less is more preferable. The warm steam emitted from the water-containing body 3 in the storage section 6 is not released to the side opposite the wearer's face because the moisture-impermeable second layer 61 acts as a barrier. In this way, by making the first layer 60 of the storage section 6 moisture-permeable and the second layer 61 moisture-impermeable, the warm steam emitted from the water-containing body 3 can be supplied only to the wearer's face side, allowing for efficient humidification.

[0028] Furthermore, both the first layer 60 and the second layer 61 of the storage section 6 are thermally insulating. The storage section 6 stores the water-containing body 3 after it has been heated by being irradiated with microwaves in a microwave oven or the like. When the temperature of the water-containing body 3 in the heated state drops, the time during which warm steam is generated from the water-containing body 3 becomes shorter. For this reason, in this embodiment, the first layer 60 and the second layer 61 of the storage section 6 are thermally insulating, which can prevent the temperature of the heated water-containing body 3 in the storage section 6 from dropping too quickly, thereby extending the time during which warm steam is generated from the water-containing body 3.

[0029] The first layer 60 of the storage section 6, which has the moisture permeability and heat insulation properties described above, can be made of, for example, a foamed resin sheet made of foamed polyurethane, foamed polyolefin, foamed polyvinyl chloride (PVC), etc., or a sheet-like batting fiber. Examples of fibers that make up the batting fiber include polyester fiber, polyolefin fiber, polyamide fiber, and acrylonitrile fiber.

[0030] The second layer 61 of the storage section 6, which is heat insulating and moisture-impermeable as described above, can be constructed, for example, using a foamed resin sheet or a sheet-like fiber cotton used in the first layer 60 described above, covered with a moisture-impermeable material.

[0031] In this embodiment, the storage section 6 is provided with a steam retaining layer 62 capable of retaining steam on the face-side surface of the face-side first layer 60. This steam retaining layer 62 allows some of the steam emitted from the water-containing body 3 in the storage section 6 and permeates the first layer 60 to pass through and be released toward the wearer's face, and retains some of the steam, thereby increasing the humidity between the mask body 2 and the wearer's face when the mask 1 is worn. This improves the humidifying effect, and the space between the mask body 2 and the wearer's face can be effectively humidified.

[0032] The steam-retaining layer 62 can be formed using breathable sheet-like fibers such as woven fabric or nonwoven fabric, with nonwoven fabric being preferred. Nonwoven fabrics made by spunbonding, thermal bonding, spunlace, or other methods can be used. From the standpoint of feel, thermal bonding and spunlace nonwoven fabrics are more preferred, with spunlace nonwoven fabrics being particularly preferred. Hydrophobic fibers are preferred as the fiber material for the woven and nonwoven fabrics making up the steam-retaining layer 62, as they prevent wetting and stickiness. Synthetic fibers such as polypropylene, polyethylene, and polyester can be used. Among these, polypropylene and polyethylene are preferred from the standpoints of flexibility and productivity. From the standpoints of steam-retaining function and flexibility, the steam-retaining layer 62 is preferably formed by overlapping multiple (two in this embodiment) sheet-like fibers (e.g., nonwoven fabrics).

[0033] Next, the water-containing body 3 is impregnated with a moisture-retaining liquid containing water as a main component, and can generate steam when heated by being irradiated with microwaves, for example, in a microwave oven. As shown in Figures 1 to 4, when the mask 1 is worn, the water-containing body 3 is housed in a heated state in the housing portion 6 of the mask body 2, and releases steam, humidifying the space between the mask body 2 and the face and supplying moisture to the oral cavity.

[0034] Although the water-containing body 3 is not particularly limited, it preferably contains a large amount of water-retaining liquid, and the amount of water-retaining liquid (impregnation amount) contained in the water-containing body 3 is preferably 6 g or more, more preferably 12 g or more, and even more preferably 16 g or more. Furthermore, from the viewpoint of the effect of the weight of the water-containing body 3 on the feeling of use 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. When 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, and the water-containing body 3 does not cool down easily after being heated, so the temperature of the water-containing body 3 that has been heated to a high temperature can be maintained for a long time. In this way, when the mask 1 is worn, the water-containing body 3 can be kept warm for a long time, so warm steam can be generated for a long time and a good feeling of use can be obtained.

[0035] In order to retain such a quantity of water-retaining liquid, the weight of the water-retaining body 3 is 500 g / m 2 It is preferable that the weight is 800 g / m or more. 2 On the other hand, if the basis weight is too large, the water-containing body 3 becomes hard, and when the mask 1 is worn, the water-containing body 3 does not deform to fit the shape of the face around the mouth of the wearer, which may cause discomfort to the wearer. Therefore, the basis weight of the water-containing body 3 is set to 1500 g / m or more. 2 It is preferable that the thickness is 1000 g / m or less. 2 More preferably, it is:

[0036] In this embodiment, the water-containing body 3 has a rectangular shape in a plan view. Since the water-containing body 3 is used around the mouth of the wearer when wearing the mask 1, its size is, for example, preferably 4 cm to 14 cm in the horizontal direction and 2 cm to 7 cm in the vertical direction, and more preferably 7 cm to 11 cm in the horizontal direction and 3 cm to 6 cm in the vertical direction. In terms of area, for example, 8 cm 2 More than 98cm 2 Preferably less than 25cm 2 More than 50cm 2 More preferably, it is:

[0037] The water-containing body 3 covers the wearer's mouth when the mask 1 is worn, and therefore the water-containing body 3 has an air vent 30 formed therein so as not to interfere with the wearer's breathing through the mouth. This facilitates breathing through the mouth of the wearer when the mask 1 is worn. The air vent 30 may be composed of multiple small-diameter holes or one or more notches, but is preferably composed of a notch extending in the vertical direction at the center of the left-right direction of the water-containing body 3. This makes it easier to fold the water-containing body 3 along the air vent 30 at the center of the left-right direction. As described above, in order to impregnate the water-containing body 3 with a large amount of water, the basis weight of the water-containing body 3 needs to be large. However, if the basis weight is large, the water-containing body 3 becomes stiff, and the water-containing body 3 does not conform to the shape of the wearer's face around the mouth when the mask 1 is worn, which may cause discomfort to the wearer. However, if the ventilation holes 30 make it easier for the water-containing body 3 to bend at the center position in the left-right direction, even if the basis weight of the water-containing body 3 is large, the water-containing body 3 will deform to fit the shape of the wearer's face around the mouth when the mask 1 is worn, and the wearer will not feel uncomfortable.

[0038] In this embodiment, the air vent 30 is formed so as to extend upward from the lower edge of the water-containing body 3, but it may also be formed so as to extend downward from the upper edge of the water-containing body 3, or so as to extend downward and upward from the upper and lower edges of the water-containing body 3, respectively, or so as to extend vertically in the region between the upper and lower edges of the water-containing body 3.

[0039] The hydrous body 3 can be formed from various fiber materials, including hydrophilic fibers and blended fibers of hydrophilic fibers and synthetic fibers. Examples of the fiber material include polyethylene, polypropylene, polyester, rayon, cotton, and pulp, with pulp being preferred in terms of flexibility and water retention. The method for producing such a hydrous body 3 is not particularly limited, but it can be produced by an airlaid method or the like, and from the viewpoints of productivity, processability, and durability, it is preferred to blend pulp, which is the main component, with heat-fusible fibers such as polyethylene in a predetermined ratio.

[0040] For example, when the water-containing body 3 is made of pulp, the ratio of pulp to heat-fusible fiber can be 60:40 to 80:20. The water-containing body 3 can have a single-layer or multi-layer structure. However, from the viewpoint of durability and water retention, a three-layer structure in which the fiber material is sandwiched between a pair of nonwoven fabrics is preferable. In this case, the layer sandwiched between the pair of nonwoven fabrics is called the middle layer, and the layers consisting of the pair of nonwoven fabrics are called the end layers. The nonwoven fabrics of the end layers can be made of the same material or different materials. Examples of materials for these nonwoven fabrics include hydrophilic fibers, hydrophobic fibers, synthetic fibers, and blended fibers of hydrophilic fibers and synthetic fibers. Examples of hydrophilic fibers include rayon and cotton, and rayon is preferred. Making the material hydrophilic has the advantage of facilitating moisture absorption by the pulp during production, thereby facilitating production. Examples of hydrophobic fibers include polyesters such as polyethylene, polypropylene, and polyethylene terephthalate, and polyethylene and polypropylene are preferred. Making the material hydrophobic has the advantage of preventing wetting and stickiness. Therefore, it is preferable that the surface facing the wearer is made of hydrophobic fibers, and the opposite surface is made of hydrophilic fibers such as rayon. 2 More than 50g / m 2 It is preferable to do the following:

[0041] The water-retaining liquid impregnated into the water-containing body 3 may be water alone, or it may be primarily water with a polyol blended into the water. Examples of polyols include glycerin, dipropylene glycol, 1,3-butylene glycol, propylene glycol, sorbitol, 1,2-pentanediol, and 1,2-hexanediol. Among these, glycerin is preferred for its safety. Other suitable additives include preservatives such as methylparaben and phenoxyethanol, moisturizers such as hyaluronate and betaine, plant extracts, water-soluble thickeners such as xanthan gum, hydroxypropylmethylcellulose (HPMC), hydroxyethylcellulose (HEC), hydroxypropylcellulose (HPC), agar, guar gum, and carrageenan, fragrances such as eucalyptus and mint, and surfactants (nonionic surfactants, amphoteric surfactants, and anionic surfactants) that solubilize fragrances. Before wearing the mask 1, that is, before storing it in the storage section 6, the water-containing body 3 is preferably stored in a bag made of an impermeable aluminum laminate film, aluminum-deposited PET film, transparent (silica)-deposited PET film, or the like.

[0042] According to the mask 1 of the present embodiment described above, after being irradiated with microwaves, for example, in a microwave oven, the heated water-containing body 3 generates warm steam, which humidifies the space between the mask body 2 and the wearer's face. This replenishes moisture in the oral cavity, preventing dryness of the oral cavity. Furthermore, since the water-containing body 3 is stored in the storage section 6 of the mask body 2 in a heated state, steam is generated immediately after the mask 1 is put on, and since it does not take time for steam to be generated, a sufficient amount of steam can be supplied immediately after the mask 1 is put on.

[0043] Furthermore, according to the mask 1 of this embodiment, a vapor retaining layer 62 capable of retaining vapor is provided on the face-side surface of the first layer 60 on the face side of the housing portion 6, and thus the vapor retaining layer 62 retains a portion of the vapor that is emitted from the water-containing body 3 in the housing portion 6 and permeates the first layer 60. Therefore, the vapor retaining layer 62 increases the humidity between the mask body 2 and the wearer's face when the mask 1 is worn, improving the humidifying effect and enabling effective humidification of the space between the mask body 2 and the wearer's face.

[0044] Furthermore, according to the mask 1 of this embodiment, the first layer 60 and the second layer 61 of the storage portion 6 have heat insulating properties, which can prevent a rapid decrease in the temperature of the heated water-containing material 3 in the storage portion 6. Therefore, warm steam can be generated from the water-containing material 3 for a longer period of time.

[0045] Furthermore, according to the mask 1 of this embodiment, the first layer 60 on the face side of the storage section 6 is moisture-permeable, and the second layer 61 on the cover section 5 side is moisture-impermeable, so that warm steam emitted from the water-containing body 3 in the storage section 6 passes through the moisture-permeable first layer 60 and is released to the wearer's face side, but the moisture-impermeable second layer 61 acts as a barrier to prevent steam from being released to the side opposite the wearer's face. Therefore, warm steam emitted from the water-containing body 3 can be supplied only to the wearer's face side, allowing for efficient humidification.

[0046] Furthermore, according to the mask 1 of this embodiment, the upper edge of the first layer 60 on the face side of the storage section 6 is located higher than the upper edge of the second layer 61 on the covering section 5 side and is joined to the face-side surface of the covering section 5, so that when the mask 1 is worn, the first layer 60 is interposed between the upper opening of the storage section 6 and the wearer's face. Therefore, even if warm steam emitted from the water-containing body 3 in the storage section 6 is released from the upper opening of the storage section 6, it is not released toward the wearer's face until it has passed through the first layer 60, and therefore the steam can be prevented from directly hitting the wearer's face.

[0047] Furthermore, according to the mask 1 of this embodiment, the storage portion 6 is attached to the cover portion 5 at a position lower than the upper edge 50 of the cover portion 5. Therefore, when the mask 1 is worn, the storage portion 6 is positioned below the wearer's nose, so the nose is not covered by the water-containing body 3, allowing the wearer to breathe easily through the nose, and the water-containing body 3 does not come into contact with the nose, reducing the comfort of wearing the mask 1.

[0048] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications are possible 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 accommodation section 6 of the mask body 2, but it may also be accommodated in the accommodation section 6 of the mask body 2 after being heated by being irradiated with microwaves.

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

[0051] In addition, in the above embodiment, the first layer 60 and the second layer 61 of the storage section 6 both have thermal insulation properties, but only one of them may have thermal insulation properties, or neither may have thermal insulation properties.

[0052] In addition, in the above embodiment, the first layer 60 of the storage section 6 is moisture permeable and the second layer 61 is moisture impermeable, but both may be moisture permeable.

[0053] In addition, in the above embodiment, the storage section 6 is attached to the cover section 5 at a position below the upper edge 50 of the cover section 5, but it may also be attached to the cover section 5 at the position of the upper edge 50 of the cover section 5.

[0054] Furthermore, in the above embodiment, the upper edge of the first layer 60 on the face side of the storage section 6 is positioned higher than the upper edge of the second layer 61 on the cover section 5 side and joined to the cover section 5, but the upper edge of the second layer 61 on the cover section 5 side may also be positioned higher than the upper edge of the first layer 60 on the face side and joined to the cover section 5.

[0055] In the above embodiment, the water-containing body 3 has the air vents 30 formed therein, but the air vents 30 do not necessarily have to be formed therein.

[0056] Furthermore, in the above 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 straight lines, but for example, the upper edge 50 may be formed in a curved or bent line that is convex toward the upward direction, and / or the lower edge 51 may be formed in a curved or bent line that is convex toward the downward direction, and / or the left and right side edges 52, 53 may be formed in a curved or bent line that is convex toward the inward direction.

[0057] In addition, in the above embodiment, since the storage section 6 covers the wearer's mouth when the mask 1 is worn, the storage section 6 may be provided with an air vent to prevent the storage section 6 from interfering with breathing through the wearer's mouth.
