Description

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

2. Description of the Related Art Conventionally, masks have been widely used as a protective measure against fine dust such as pollen and yellow sand, and as a preventive measure against infection with viruses and bacteria. Also, recently, various masks have been proposed and various masks have been proposed. For example, during sleep, since there is no swallowing of food, drink, saliva, etc., the oral cavity may be easily dried. In addition, the air is generally dry in winter, and even outside of winter, air conditioners are operating in the office year-round. Therefore, even in the daytime, there are many environments where the air is easily dried, and the oral cavity is easily dried.

In order to prevent this, for example, Patent Document 1 discloses a mask having a humidifying function. In the mask of Patent Document 1, a water-containing body containing water and a heating element such as a body warmer that adheres to the water-containing body are attached to a mask body that covers the nose and mouth. By heating a water-containing body containing water with a heating element, warm steam is generated, which humidifies the space between the mask and the face and replenishes the mouth with water, thereby preventing the mouth from drying.

However, in the mask of Patent Document 1, since the hydrated body is warmed by the body warmer, it takes time to generate heat from the body warmer, and the hydrated body is indirectly heated. It takes time and the amount of steam immediately after wearing the mask is insufficient.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a mask that can supply a sufficient amount of vapor immediately after wearing.

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 a part of the wearer's face, and a water-containing body that contains moisture and is heated by being irradiated with microwaves to emit steam, and the mask body is heated. It is characterized in that it is provided with a housing portion for housing the hydrated body.

In the mask of the present invention, the mask main body includes a cover portion that covers a part of the face of the wearer, and the bag-shaped storage portion that is provided on the face-side surface of the cover portion. Comprises at least a first layer on the face side and a second layer on the side of the cover part, between which the hydrate is inserted, the first layer having moisture permeability, and the face on the face side of the first layer. Is preferably provided with a vapor retaining layer capable of retaining vapor.

Further, in the mask of the present invention, it is preferable that the first layer and the second layer have a heat insulating property.

Moreover, in the mask of the present invention, it is preferable that the second layer is impermeable to moisture.

According to the present invention, when the mask is worn, for example, warm steam is generated from the heated hydrated body after being irradiated with microwaves in a microwave oven or the like, which causes a gap between the mask body and the wearer's face. Be humidified. Therefore, since the oral cavity is replenished with water, it is possible to prevent the oral cavity from drying.

In addition, since the hydrated body is stored in the storage unit in a heated state, it immediately generates warm steam, and it does not take time from immediately after wearing the mask until steam is generated. A large amount of steam can be supplied.

It is (A) front view of the mask of this embodiment, and is a (B) rear view. It is a X1-X1 schematic sectional drawing of FIG. It is a rear view of (A), a front view of (B), and (C) X2-X2 schematic sectional drawing of an accommodation part. It is a (A) front view of a water containing body, and is a (B) side view.

Hereinafter, the actual mode of the present invention will be described with reference to the accompanying drawings. 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 under the eyes, particularly the nose and mouth), and a water-containing body 3 containing water. The mask body 2 includes a cover portion 5 that covers a part of the wearer's face when worn, and a bag-shaped accommodation portion 6 provided on the face side of the cover portion 5. The water-containing body 3 is housed in the housing portion 6 of the mask body 2 and then heated by being irradiated with microwaves in, for example, a microwave oven. As a result, warm vapor is emitted from the hydrated body 3 when the mask 1 is worn.

The cover portion 5 has a rectangular shape in a plan view in the present embodiment. When the mask 1 is worn, the covering part 5 has an upper edge 50 extending laterally under the eyes of the wearer's face, a lower edge 51 extending laterally under the lower jaw (or below the jaw), an upper edge 50 and a lower edge 51. And left and right side edges 52, 53 for connecting the. The size of the cover portion 5 is not particularly limited, and may be any size as long as the left and right side edges 52, 53 cross the cheek and cover part of the nose, mouth, lower jaw and cheek of the face.

In addition, the cover portion 5 has a flat shape before the mask 1 is worn (when not in use) in this embodiment. That is, the cover portion 5 of the present embodiment has a different structure from the three-dimensional type cover 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 and folded by a folding portion extending in the vertical direction at the center in the horizontal direction, Even if the two mask pieces are unfolded, they do not become flat, and this is different from the structure that forms a large space between the nose (nostril) and the mouth when it is worn on the face. When attached to, it fits more closely to the face surface than the three-dimensional type cover.

The cover 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 a nonwoven fabric. Among them, non-woven fabrics by spun bond method, melt blow method, thermal bond method or spun lace method can be preferably used, and more preferably, non-woven fabrics by spun bond method from the viewpoint of touch and shape retention, such as pollen and virus. From the viewpoint of cutting performance, a non-woven fabric produced by the melt blow method can be used. Considering the above points, as a suitable layer structure of the cover portion 5, for example, an SMS layer (three-layer structure of spunbond-meltblown-spunbond) can be cited. Other than these, an S layer (spunbond single layer) or an SS layer (spunbond-spunbond two-layer structure) can be preferably mentioned. When the cover portion 5 has a laminated structure, the cover portion 5 is formed by joining the outer peripheral edges of the sheets of the respective layers with a predetermined width by a known method such as sewing, ultrasonic welding, or heat fusion. be able to.

As the fiber material of the woven cloth and the non-woven cloth forming each layer of the cover portion 5, known materials can be used, for example, natural fibers such as paper and cotton; semi-synthetic fibers such as rayon and acetate; polypropylene, polyethylene and polyester. , Synthetic fibers such as 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.

The cover portion 5 has a structure that can extend in the vertical direction. For example, the cover portion 5 is provided with at least one pleat 54 formed by at least two folds extending in the lateral direction. By expanding the pleats 54, the cover 5 can be extended in the vertical direction, and the size of the cover 5 can be freely adjusted according to the size of the face of the wearer.

Ear-hook bands 7 are attached to the left and right side edges 52, 53 of the cover 5 as holding means for holding the cover 5 on the wearer's face. The ear hanging band 7 can be attached to the cover portion 5 by a known method such as sewing, ultrasonic welding, or heat fusion. The material of the ear-hook band 7 is not particularly limited, but it is preferably a stretchable material such as polyester. As the means for holding the cover portion 5, various means other than the ear hanging band 7 may be used.

A linear nosepiece 8 made of a plastic resin such as polyethylene or a biodegradable resin is provided at a position inside the upper edge 50 of the cover portion 5. Since the nose piece 8 prevents a gap from being formed between the nose of the wearer and the cover portion 5, the cover portion 5 can be fitted to the face. The nosepiece 8 can be fixed at a predetermined position by, for example, being built in the cover portion 5 and joining the sheets of the respective layers constituting the cover portion 5 at the upper and lower positions thereof by, for example, ultrasonic welding.

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 covering portion 5 side, and the upper edge of the outer peripheral edge of the second layer 61 is The removed portion is joined to the first layer 60. As a result, the accommodation portion 6 has an opening formed in the upper portion, and is formed into a bag shape in which the water-containing body 3 can be inserted and held between the first layer 60 and the second layer 61. In the present embodiment, in the accommodation portion 6, the upper edge of the second layer 61 is located below the upper edge of the first layer 60, and it is easy to insert the hydrated body 3 into the accommodation portion 6 from the upper opening. ing.

The accommodating portion 6 is attached to the cover portion 5 by bonding the first layer 60 on the face side to the face side surface of the cover portion 5 by a known method such as sewing, ultrasonic welding, or heat fusion. There is. In the present embodiment, in the housing portion 6, 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 cover portion 5. As a result, the accommodation portion 6 is not obstructed when the covering portion 5 is expanded in the longitudinal direction by expanding the pleats 54, and the accommodation portion 6 is not restrained by the covering portion 5 and the weight of the water-containing body 3 increases. Since it is easy to bring the water-containing body 3 close to the wearer's face, the steam emitted from the water-containing body 3 can be efficiently supplied to the nose and mouth.

Further, since the upper edge of the first layer 60 on the face side is joined to the face side surface of the cover part 5, when the mask 1 is worn, it is between the upper opening of the housing part 6 and the face of the wearer. The first layer 60 is interposed. Thereby, even if the warm vapor generated from the water-containing body 3 in the housing portion 6 is discharged from the upper opening of the housing portion 6, it is not discharged to the wearer's face side after passing through the first layer 60. It is possible to prevent the steam from directly hitting the wearer's face.

In the present embodiment, the housing portion 6 is attached to the cover portion 5 at a position below the upper edge 50 of the cover portion 5. Since the upper edge 50 of the cover portion 5 extends laterally under the eyes of the wearer's face when the mask 1 is worn, when the storage portion 6 is attached to the position of the upper edge 50 of the cover portion 5, the storage portion 6 The hydrated body 3 in the inside covers the nose. If the nose is covered with the hydrated body 3, it may be difficult to breathe through the nose, and the hydrated body 3 may hit the nose to reduce the wearing comfort of the mask 1. Therefore, in the present embodiment, the housing portion 6 has a predetermined height (for example, 15 mm or more) from the upper edge 50 of the cover portion 5 so that the housing body 6 is placed under the nose of the wearer when the mask 1 is worn. It is attached to the cover portion 5 at a position shifted downward (30 mm or less).

The size of the accommodating portion 6 may be any size that allows the hydrated body 3 to be inserted therein. For example, the lateral length can be 50 mm or more and 150 mm or less, and the longitudinal length can be 30 mm. It can be 80 mm or less.

The first layer 60 on the face side of the housing portion 6 has moisture permeability. The moisture permeability is a property that allows vapor (water molecules) to pass therethrough. For example, the moisture permeability is preferably 1000 g/m ² /24 h or more, and more preferably 2000 g/m ² /24 h or more. It is more preferably 3000 g/m ² /24 h or more. As a result, the warm steam generated from the water-containing body 3 in the housing portion 6 passes through the first layer 60 and is discharged to the wearer's face side. On the other hand, the second layer 61 on the cover portion 5 side of the housing portion 6 is impermeable to moisture. The non-moisture permeability is not limited to the property of completely impervious to steam (water molecules), but also includes the property of slightly penetrating steam (water molecules). For example, the water vapor permeability is preferably 350 g/m ² /24 h or less, more preferably 300 g/m ² /24 h or less. The warm vapor emitted from the hydrated body 3 in the housing portion 6 is not emitted on the side opposite to the face of the wearer because the non-moisture permeable second layer 61 serves as a barrier. In this way, by making the first layer 60 of the housing portion 6 moisture-permeable and making the second layer 61 moisture-impermeable, the warm steam generated from the water-containing body 3 can be supplied only to the wearer's face side, and the efficiency can be improved. Can be well humidified.

In addition, both the first layer 60 and the second layer 61 of the housing portion 6 have heat insulating properties. Although the hydrated body 3 that has been heated by being irradiated with microwaves in a microwave oven or the like is housed in the housing unit 6, when the temperature of the hydrated body 3 in a heated state decreases, warm steam is emitted from the hydrated body 3. It will occur in a shorter time. Therefore, in the present embodiment, the first layer 60 and the second layer 61 of the housing portion 6 are made heat insulating, which prevents the temperature of the heated hydrated body 3 in the housing portion 6 from rapidly decreasing. As a result, the time during which warm steam is emitted from the hydrated body 3 can be extended.

The first layer 60 of the accommodation portion 6 having the moisture permeability and the heat insulating property described above uses, for example, a foamed resin sheet made of foamed polyurethane, foamed polyolefin, foamed polyvinyl chloride (PVC), or a sheet-shaped fiber cotton. Can be configured. Examples of fibers constituting the fiber cotton include polyester fibers, polyolefin fibers, polyamide fibers, and acrylonitrile fibers.

The second layer 61 of the accommodating portion 6 having the heat insulating property and the non-moisture permeability described above covers, for example, the foamed resin sheet or the sheet-shaped fiber cotton used for the above-mentioned first layer 60 with the non-moisture impermeable material. It can be configured by using.

In the present embodiment, the housing portion 6 is provided with a vapor holding layer 62 capable of holding vapor on the face side of the face-side first layer 60. The vapor retaining layer 62 allows a portion of the vapor emitted from the hydrated body 3 in the accommodating portion 6 and permeating the first layer 60 to pass through as it is and to be released to the wearer's face side to retain a portion thereof. This increases the humidity between the mask body 2 and the face of the wearer when wearing the mask 1. As a result, the humidifying effect is improved, and the mask body 2 and the wearer's face can be effectively humidified.

The vapor retaining layer 62 can be formed by using air-permeable sheet-like fibers such as woven cloth and non-woven cloth, and among them, non-woven cloth can be preferably used. As the non-woven fabric, a non-woven fabric produced by a spunbond method, a thermal bond method, a spunlace method or the like can be used, but a nonwoven fabric produced by the thermal bond method or the spunlace method can be more preferably used from the viewpoint of touch, and a non-woven fabric produced by the spunlace method. Can be used particularly preferably. As the fiber material of the woven fabric and the non-woven fabric which constitutes the vapor retaining layer 62, hydrophobic fibers can be preferably used from the viewpoint of preventing wetting and stickiness, and for example, synthetic fibers such as polypropylene, polyethylene and polyester are used. You can Among them, polypropylene and polyethylene can be preferably used from the viewpoints of flexibility and productivity. In addition, it is preferable that the vapor retaining layer 62 be formed by stacking a plurality of (two in the present embodiment) sheet-shaped fibers (for example, non-woven fabric) from the viewpoint of the vapor retaining function and flexibility.

Next, the hydrated body 3 is impregnated with a water retaining liquid containing water as a main component, and can be heated by being irradiated with microwaves in a microwave oven or the like to generate steam. As shown in FIGS. 1 to 4, the hydrated body 3 releases steam by being accommodated in the accommodation part 6 of the mask body 2 in a heated state when the mask 1 is worn, so that the water content between the mask body 2 and the face is increased. Moisturize and supply water to the oral cavity.

The water-containing body 3 is not particularly limited, but preferably contains a large amount of water-holding liquid, and the water-holding liquid amount (impregnation amount) contained in the water-containing body 3 is preferably 6 g or more, 12 g More preferably, it is more preferably 16 g or more. Further, from the viewpoint of the influence of the weight of the hydrated body 3 on the feeling during use, the impregnated amount of the hydrated body 3 is preferably 30 g or less, more preferably 24 g or less, and more preferably 20 g or less. Is more preferable. Since the hydrated body 3 contains a large amount of water retention liquid, a large amount of steam can be supplied to the oral cavity, and the hydrated body 3 becomes difficult to cool after being heated. The temperature of can be maintained long. In this way, when the mask 1 is worn, the heat retention time of the hydrated 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.

In order to retain such an amount of the water retaining liquid, the basis weight of the hydrated body 3 is preferably 500 g/m ² or more, more preferably 800 g/m ² or more. On the other hand, if the basis weight is too large, the hydrated body 3 becomes hard, so that the hydrated body 3 is not deformed along the facial shape of the wearer's mouth when the mask 1 is worn, and the wearer may feel uncomfortable. .. Therefore, the basis weight of the water-containing body 3 is more preferably preferably at 1500 g / ^{m 2} or less, 1000 g / ^{m 2} or less.

The hydrated body 3 has a rectangular shape in plan view in the present embodiment. Since the hydrated body 3 is used at the wearer's mouth when the mask 1 is worn, the size thereof is preferably, for example, 4 cm or more and 14 cm or less in the lateral direction and 2 cm or more and 7 cm or less in the longitudinal direction. It is more preferably 7 cm or more and 11 cm or less and 3 cm or more and 6 cm or less in the longitudinal direction. The area 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.

Since the hydrated body 3 covers the mouth of the wearer when the mask 1 is worn, the hydrated body 3 is provided with a vent hole 30 so that the hydrated body 3 does not prevent breathing by the wearer's mouth. This facilitates breathing through the mouth of the wearer when wearing the mask 1. The vent hole 30 may be formed of a plurality of small-diameter holes, or may be formed of one or a plurality of notches, but a notch that extends in the vertical direction at the center position of the hydrous body 3 in the left-right direction. Preferably. Thereby, the water-containing body 3 can be easily bent along the ventilation hole 30 at the center position in the left-right direction. In order to impregnate the hydrated body 3 with a large amount of water, it is necessary to increase the basis weight of the hydrated body 3 as described above, but the larger the basis weight, the harder the hydrated body 3 is, and the hydrated body is worn when the mask 1 is worn. Since 3 does not follow the facial shape of the wearer's mouth, the wearer may feel uncomfortable. However, if the hydrated body 3 can be easily bent at the center position in the left-right direction by the vent hole 30, even if the hydrated body 3 has a large basis weight, the hydrated body 3 conforms to the facial shape of the wearer's mouth when the mask 1 is worn. Therefore, the wearer does not feel uncomfortable.

In addition, although the vent hole 30 is formed to extend upward from the lower edge of the hydrous body 3 in the present embodiment, it may be formed to extend downward from the upper edge of the hydrous body 3. However, it may be formed so as to extend downward and upward from the upper edge and the lower edge of the hydrated body 3, respectively, and extend vertically in the region between the upper edge and the lower edge of the hydrated body 3. It may be formed in this way.

The hydrated body 3 can be formed of various fiber materials, and can be formed of hydrophilic fibers or a mixed fiber of hydrophilic fibers and synthetic fibers. Examples of the fiber material include polyethylene, polypropylene, polyester, rayon, cotton, pulp and the like, and from the viewpoint of flexibility and water retention, pulp is preferable. The method for producing such a hydrated body 3 is not particularly limited, but it can be produced by the air laid method or the like, and from the viewpoint of productivity, processability and durability, pulp which is the main component is heat-melted with polyethylene or the like. It is preferable to mix the adhesive fiber in a predetermined ratio.

For example, when the water-containing body 3 is formed of pulp, the ratio of pulp:heat-fusible fiber is 60:40 to 80:20. The water-containing body 3 may have a single-layer structure or a multi-layer structure, but from the viewpoint of durability and water retention, it is preferable to have a three-layer structure in which a fibrous material is sandwiched between a pair of nonwoven fabrics. At this time, the layer sandwiched between the pair of non-woven fabrics is called the middle layer, and the layer consisting of the pair of non-woven fabrics is called both end layers. The nonwoven fabrics of both end layers may be made of the same material or different materials. Examples of the material of these non-woven fabrics include hydrophilic fibers, hydrophobic fibers, synthetic fibers, or mixed-spun fibers of hydrophilic fibers and synthetic fibers, and examples of hydrophilic fibers include rayon and cotton. Rayon is preferred. The hydrophilic property has an advantage that the moisture is easily absorbed by the pulp during the production, which facilitates the production. Examples of the hydrophobic fiber include polyesters such as polyethylene, polypropylene and polyethylene terephthalate, and polyethylene and polypropylene are preferable. The hydrophobic property has the advantage of preventing wetting and stickiness. Therefore, it is preferable that the surface facing the wearer side is made of hydrophobic fiber and the surface opposite to the side is made of hydrophilic fiber such as rayon. The pair of nonwoven fabrics described above preferably have a basis weight of, for example, 20 g/m ² or more and 50 g/m ² or less.

The water retaining liquid with which the hydrated body 3 is impregnated may be only water, but it is also possible to use water as a main component and mix a polyol with water. Examples of the polyol include glycerin, dipropylene glycol, 1,3-butylene glycol, propylene glycol, sorbitol, 1,2-pentanediol, 1,2-hexanediol, and among them, glycerin is preferable from the viewpoint of safety. .. In addition to these, preservatives such as methylparaben and phenoxyethanol, moisturizers such as hyaluronate and betaine, plant extracts, xanthan gum and hydroxypropylmethylcellulose (HPMC), hydroxyethylcellulose (HEC), hydroxypropylcellulose (HPC), agar. , Water-soluble thickeners such as guar gum and carrageenan, fragrances such as eucalyptus and mint, and surfactants (nonionic surfactants, amphoteric surfactants, anionic surfactants) that solubilize fragrances can be used as appropriate. .. Before the mask 1 is worn, that is, before being accommodated in the accommodating portion 6, the water-containing body 3 is accommodated in a bag made of an impermeable aluminum laminate film, an aluminum vapor-deposited PET film, a transparent (silica) vapor-deposited PET film, or the like. It is preferable to set.

According to the mask 1 of the present embodiment described above, warm steam is generated from the heated hydrated body 3 after being irradiated with microwaves in, for example, a microwave oven, which causes the mask body 2 and the face of the wearer to be exposed. The space between them is humidified. Therefore, since the oral cavity is replenished with water, it is possible to prevent the oral cavity from drying. Further, since the water-containing body 3 is housed in the housing portion 6 of the mask body 2 in a heated state, it immediately emits steam immediately after wearing the mask 1, and it does not take time to generate steam. A sufficient amount of steam can be supplied immediately after wearing the mask 1.

Further, according to the mask 1 of the present embodiment, since the vapor holding layer 62 capable of holding vapor is provided on the face side of the first layer 60 on the face side of the housing portion 6, the vapor holding layer 62 is used. A part of the vapor emitted from the water-containing body 3 in the housing portion 6 and transmitted through the first layer 60 is retained. Therefore, the vapor retention layer 62 increases the humidity between the mask body 2 and the face of the wearer when the mask 1 is worn, so that the moisturizing effect is improved and the effect between the mask body 2 and the face of the wearer is improved. Can be humidified.

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 a heat insulating property, the temperature of the heated hydrated body 3 in the accommodating portion 6 rapidly increases. Can be prevented. Therefore, warm steam can be generated from the hydrated body 3 for a longer time.

Further, according to the mask 1 of the present embodiment, since the first layer 60 on the face side of the containing portion 6 has moisture permeability and the second layer 61 on the covering portion 5 side has no moisture permeability, the containing portion 6 The warm vapor generated from the hydrated body 3 inside passes through the moisture-permeable first layer 60 and is discharged to the wearer's face side, but the moisture-impermeable second layer on the side opposite to the wearer's face. The layer 61 serves as a barrier and vapor is not released. Therefore, since the warm steam generated from the water-containing body 3 can be supplied only to the wearer's face side, the humidification can be efficiently performed.

Further, according to the mask 1 of the present 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 the covering portion 5 is covered. Since the mask 1 is joined to the face side, the first layer 60 is interposed between the upper opening of the housing 6 and the wearer's face when the mask 1 is worn. Therefore, even if the warm steam generated from the hydrated body 3 in the housing portion 6 is discharged from the upper opening of the housing portion 6, it is not discharged to the wearer's face side after passing through the first layer 60, and thus the steam is not discharged. Can be prevented from directly contacting the wearer's face.

Further, according to the mask 1 of the present embodiment, the housing portion 6 is attached to the cover portion 5 at a position below the upper edge 50 of the cover portion 5. Therefore, since the container 6 is placed under the nose of the wearer when the mask 1 is worn, the nose is not covered with the water-containing body 3 and the wearer can easily breathe through the nose. The hydrated body 3 does not hit the nose and the feeling of wearing the mask 1 does not deteriorate.
