Description

TECHNICAL FIELD The present invention relates to masks worn on the face, and more particularly to masks that emit steam.

2. Description of the Related Art Conventionally, masks have been widely used as a defense against fine dust such as pollen and yellow sand, and as a measure against infections such as viruses and bacteria. Furthermore, recently, the functions of masks have diversified, and various masks have been proposed. For example, during sleep, there is no swallowing of food, drinks, saliva, etc., so the oral cavity may become easily dry. Additionally, the air is generally dry during the winter, and even outside of the winter, air conditioners are running in offices all year round. Therefore, there are many environments where the air tends to be dry even during the day, making the oral cavity more likely to dry out.

To prevent this, for example, Patent Document 1 discloses a mask having a humidifying function. In the mask of Patent Document 1, the mask body that covers the nose and mouth is provided with a storage part that accommodates a water-containing body containing water, and the water contained in the water-containing body humidifies the space between the mask and the face, and the mouth is moistened. This prevents oral dryness.

JP2007-319421A

In the mask of Patent Document 1, in order to properly replenish the moisture contained in the water-containing body to the oral cavity, the layer on the opposite side of the face side of the accommodating part must be non-breathable, so that the water in the hydrated body flows through the face of the accommodating part. Preferably, the release is from the side layer. However, if the layer on the opposite side of the face side of the accommodating part is non-breathable, for example when wearing a mask while sleeping, the accommodating part will cover the wearer's mouth, but the non-breathable layer will cause the mask to cover the wearer's mouth. The problem is that it is difficult to breathe through the mouth because the body is covered.

The present invention was made to solve the above problems, and an object of the present invention is to provide a mask that allows the wearer to easily breathe through the mouth when wearing the mask.

The present invention relates to a mask worn on the face. The mask of the present invention includes a mask main body and a water-containing body containing water, and the mask main body includes a cover portion that covers a part of the wearer's face, and a bag provided on the face side surface of the cover portion. The accommodating part is characterized in that the accommodating part is provided with a ventilation hole in an area corresponding to the wearer's mouth when worn.

In the mask of the present invention, it is preferable that the ventilation hole extends a predetermined length above the lower edge of the accommodating portion.

Moreover, in the mask of the present invention, it is preferable that the ventilation hole is located at the center of the accommodation portion in the left-right direction.

Furthermore, in the mask of the present invention, the housing section includes at least a first layer on the face side between which the water-containing body is inserted and a second layer on the cover side, and the first layer has moisture permeability. The second layer is preferably moisture-impermeable.

According to the present invention, when the mask is worn, the accommodating part is provided with ventilation holes in the area corresponding to the wearer's mouth, so even if the wearer's mouth is covered by the accommodating part, the wearer can still Can breathe easily.

It is (A) a front view of the mask of this embodiment, and (B) is a back view. 2 is a schematic cross-sectional view taken along line X1-X1 in FIG. 1. FIG. (A) is a rear view, (B) is a front view, and (C) is a schematic cross-sectional view taken along X2-X2 of the accommodating portion. It is (A) a front view of a hydrous body, and (B) is a side view. FIG. 2 is a perspective view of a wearer wearing the mask of this embodiment on his/her face.

Hereinafter, embodiments 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 main body 2 includes a cover part 5 that covers a part of the wearer's face when worn, and a bag-shaped accommodating part 6 provided on the face side surface of the cover part 5. The water-containing body 3 is accommodated in the accommodating portion 6 of the mask body 2. In this embodiment, the water-containing body 3 is heated by being irradiated with microwaves in, for example, a microwave oven after being accommodated in the housing portion 6 of the mask body 2 . As a result, warm steam is emitted from the water-containing body 3 when the mask 1 is worn.

In this embodiment, the cover portion 5 has a rectangular shape in plan view. When the mask 1 is worn, the cover part 5 has an upper edge 50 extending laterally under the eyes of the wearer's face, a lower edge 51 extending laterally across the lower jaw (or under the jaw), and the upper edge 50 and the lower edge 51. It has left and right side edges 52, 53 connecting the two. The size of the covering portion 5 is not particularly limited, and may be of a size such that the left and right side edges 52, 53 traverse the cheeks and cover part of the nose, mouth, lower jaw, and cheeks of the face.

Further, in this embodiment, the cover portion 5 has a flat shape before the mask 1 is worn (when not in use). That is, the cover part 5 of this embodiment has a structure different from that of a three-dimensional type cover part. 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 with a folding part extending vertically in the center of the horizontal direction. Even when the two mask pieces are unfolded, they do not form a flat shape, and are different from those with a structure that creates a large space between the bottom of the nose (nostrils) and the mouth when worn on the face. When worn on the face, it fits more closely to the surface of the face than a 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 configured using a breathable sheet such as a woven fabric or a nonwoven fabric. Among these, nonwoven fabrics made by spunbond method, melt blowing method, thermal bonding method, or spunlace method can be preferably used. More preferably, from the viewpoint of texture and shape retention, nonwoven fabrics made by spunbond method are used to prevent pollen, viruses, etc. From the viewpoint of cutting performance, a nonwoven fabric produced by melt blowing can be used. In consideration of the above points, a suitable layered structure of the cover portion 5 may include, for example, an SMS layer (three-layered structure of spunbond, meltblown, and spunbond). In addition, preferred examples include an S layer (single layer of spunbond) and an SS layer (two-layer structure of spunbond and spunbond). When the cover part 5 has a laminated structure, the cover part 5 is formed by joining the outer peripheral edges of the sheets of each layer to a predetermined width by a known method such as sewing, ultrasonic welding, heat fusion, etc. be able to.

Known fiber materials can be used for the woven and non-woven fabrics constituting each layer of the cover 5, such as 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 these, 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 texture.

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

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

A linear nose piece 8 made of a plastic resin such as polyethylene, a biodegradable resin, or the like is provided at a position inside the upper edge 50 of the cover portion 5 . The nosepiece 8 prevents a gap from forming 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 is built into the cover part 5, for example, and can be fixed at a predetermined position by joining the sheets of each layer constituting the cover part 5 at the upper and lower positions, for example, by ultrasonic welding.

Next, as shown in FIGS. 1 to 3, the housing part 6 has a first layer 60 on the face side and a second layer 61 on the cover part 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 accommodating portion 6 has an opening formed in the upper part and is formed into a bag shape 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 accommodating part 6 is located below the upper edge of the first layer 60, making it easier to insert the water-containing body 3 into the accommodating part 6 from the upper opening. ing.

The housing part 6 is attached to the cover part 5 by joining the face-side first layer 60 to the face-side surface of the cover part 5 by a known method such as sewing, ultrasonic welding, or heat fusion. There is. In the present embodiment, in the housing section 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 section 5. As a result, the accommodating part 6 does not get in the way when the covering part 5 is extended in the vertical direction by expanding the pleats 54, and the accommodating part 6 is not restrained by the covering part 5, so that the weight of the water-containing body 3 Since the water-containing body 3 can be easily brought close to the wearer's face, steam emitted from the water-containing body 3 can be efficiently supplied to the nose and mouth.

Furthermore, since the upper edge of the first layer 60 on the face side is joined to the face side surface of the covering part 5, there is a space between the upper opening of the housing part 6 and the wearer's face when wearing the mask 1. A first layer 60 is interposed. As a result, even if warm steam emitted from the water-containing body 3 in the housing part 6 is released from the upper opening of the housing part 6, it will not be released to the wearer's face side until after it has passed through the first layer 60. Steam can be prevented from directly hitting the wearer's face.

In this embodiment, the accommodating 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 covering part 5 extends laterally under the eyes of the wearer's face when wearing the mask 1, if the accommodating part 6 is attached to the position of the upper edge 50 of the covering part 5, the accommodating part 6 The nose is covered by the water-containing body 3 inside. If the nose is covered with the water-containing material 3, it becomes difficult to breathe through the nose, and the water-containing material 3 may hit the nose, reducing the feeling of wearing the mask 1. Therefore, in this embodiment, the accommodating part 6 is placed at a predetermined height (for example, 15 mm or more) higher than the upper edge 50 of the cover part 5 so that the accommodating part 6 is placed under the nose of the wearer when the mask 1 is worn. 30 mm or less) is attached to the cover part 5 at a position shifted downward.

The size of the storage part 6 may be any size that allows the water-containing body 3 to be placed inside, and 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. The length can be set to 80 mm or more.

The first layer 60 on the face side of the accommodating portion 6 has moisture permeability. This moisture permeability is a property that allows vapor (water molecules) to pass through. 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. Preferably, it is more preferably 3000 g/m ² /24 h or more. As a result, the warm steam emitted from the water-containing body 3 in the housing section 6 passes through the first layer 60 and is released toward the wearer's face. On the other hand, the second layer 61 of the housing section 6 on the cover section 5 side is non-moisture permeable. This moisture impermeability is not limited to a property that completely prevents vapor (water molecules) from passing through, but also includes a property that allows a small amount of vapor (water molecules) to pass through. For example, the moisture permeability is preferably 350 g/m ² /24 h or less, more preferably 300 g/m ² /24 h or less. The moisture-impermeable second layer 61 acts as a barrier against the warm steam emitted from the water-containing body 3 in the housing part 6 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 housing part 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, which increases efficiency. It can humidify well.

Further, both the first layer 60 and the second layer 61 of the housing portion 6 have heat insulating properties. The housing part 6 stores the water-containing body 3 that has been heated by being irradiated with microwaves in a microwave oven, etc., but when the temperature of the heated water-containing body 3 decreases, warm steam is released from the water-containing body 3. It takes less time to occur. Therefore, in this embodiment, the first layer 60 and the second layer 61 of the housing section 6 are made to have heat insulating properties, thereby preventing the temperature of the heated water-containing body 3 inside the housing section 6 from decreasing rapidly. As a result, the time during which warm steam is emitted from the water-containing body 3 can be extended.

The first layer 60 of the housing section 6 having moisture permeability and heat insulation properties described above is made of, for example, a foamed resin sheet made of foamed polyurethane, foamed polyolefin, foamed polyvinyl chloride (PVC), or a sheet-like fiber cotton. Can be configured. Examples of the fibers constituting the fiber cotton include polyester fibers, polyolefin fibers, polyamide fibers, and acrylonitrile fibers.

The second layer 61 of the accommodating portion 6 which has the above-mentioned heat insulating properties and is non-moisture permeable is made by, for example, covering the foamed resin sheet or sheet-like fiber cotton used for the first layer 60 with a non-moisture permeable material. It can be configured using

In the present embodiment, the accommodating portion 6 is provided with a vapor retention layer 62 capable of retaining vapor on the face-side surface of the first layer 60 on the face side. This vapor retaining layer 62 allows a part of the vapor that is emitted from the water-containing body 3 in the housing part 6 and passes through the first layer 60 to pass through and releases it to the face side of the wearer, and retains a part of the vapor. This increases the humidity between the mask body 2 and the wearer's face when the mask 1 is worn. Thereby, the humidification effect is improved, and the space between the mask body 2 and the wearer's face can be effectively humidified.

The vapor retention layer 62 can be constructed using breathable sheet-like fibers such as woven fabrics and nonwoven fabrics, among which nonwoven fabrics can be preferably used. As the nonwoven fabric, a nonwoven fabric made by a spunbond method, a thermal bonding method, a spunlace method, etc. can be used, but from the viewpoint of texture, a nonwoven fabric made by a thermal bonding method or a spunlace method is more preferably used, and a nonwoven fabric made by a spunlace method is more preferable. 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 viewpoint of preventing wetting and stickiness. For example, synthetic fibers such as polypropylene, polyethylene, and polyester can be used. Can be done. Among them, polypropylene and polyethylene can be preferably used from the viewpoint of flexibility and productivity. Note that the vapor retention layer 62 is preferably formed by stacking a plurality (in this embodiment, two) of sheet-like fibers (for example, nonwoven fabric) from the viewpoint of vapor retention function and flexibility.

Since the accommodating part 6 covers the wearer's mouth when wearing the mask 1, the accommodating part 6 is provided with a ventilation hole 9 so that the accommodating part 6 does not obstruct the wearer's breathing through the mouth. As shown in FIG. 5, the ventilation hole 9 is provided in a region of the accommodating portion 6 that corresponds to the wearer's mouth when the mask 1 is worn. This makes it easier for the wearer to breathe when wearing the mask 1.

In this embodiment, the ventilation hole 9 is formed by cutting out the lower edge of the housing part 6 at the center position in the left-right direction of the housing part 6, and extends a predetermined length upward from the lower edge of the housing part 6. It has an elongated shape. Note that the shape of the ventilation hole 9 is not particularly limited, and may be formed to extend a predetermined length downward from the upper edge of the housing portion 9, or may be formed so as to extend downward from the upper edge of the water-containing body 3 and the lower side. It may be formed to extend a predetermined length downward and upward from the side edge, respectively, or may be formed to extend a predetermined length vertically between the upper and lower edges of the water-containing body 3. may have been done. Further, the ventilation hole 9 may be composed of a plurality of small diameter holes.

Next, the water-containing body 3 is impregnated with a water-retaining liquid containing water as a main component, and can be heated by microwave irradiation in a microwave oven or the like to generate steam. As shown in FIGS. 1 to 4, when the mask 1 is worn, the water-containing body 3 is heated and accommodated in the accommodating portion 6 of the mask body 2, releases steam, and creates a space between the mask body 2 and the face. Humidifies and supplies moisture to the oral cavity. In this way, by heating the water-containing body 3 in a microwave oven or the like, the water-containing body 3 emits steam immediately after wearing the mask 1, and it does not take time for the steam to be generated, so the mask A sufficient amount of steam can be supplied immediately after wearing the item 1.

Although the water-containing body 3 is not particularly limited, it is preferable that it contains a large amount of water-retaining liquid, and the amount of water-retaining liquid (impregnated amount) contained in the water-containing body 3 is preferably 6 g or more, and 12 g. It is more preferable that it is above, and even more preferable that it is 16 g or more. In addition, from the viewpoint of the influence of the weight of the water-containing body 3 on the feeling of use during use, the amount of impregnated water-containing body 3 is preferably 30 g or less, more preferably 24 g or less, and 20 g or less. is even more preferable. Since the water-containing body 3 contains a large amount of water-retaining liquid, a large amount of steam can be supplied to the oral cavity, and the water-containing body 3 is difficult to cool down after being heated, so the water-containing body 3 that has become high temperature due to heating temperature can be maintained for a long time. In this way, when wearing the mask 1, 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.

Further, in order to retain such an amount of water-retaining liquid, the basis weight of the water-containing 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 water-containing body 3 becomes hard, so that the water-containing body 3 does not deform to follow the facial shape of the wearer's mouth when wearing the mask 1, and the wearer may feel uncomfortable. . Therefore, the basis weight of the water-containing body 3 is preferably 1500 g/m ² or less, more preferably 1000 g/m ² or less.

In this embodiment, the water-containing body 3 has a rectangular shape in plan view. Since the water-containing body 3 is used near the wearer's mouth when wearing the mask 1, 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; More preferably, the length is 7 cm or more and 11 cm or less, and 3 cm or more and 6 cm or less in the longitudinal direction. In addition, 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.

A vent hole 30 is provided in the water-containing body 3 at a position corresponding to the vent hole 9 of the accommodating portion 6 of the mask body 2. In this embodiment, the ventilation hole 30 is formed of a notch like the ventilation hole 9, and is formed to extend upward from the lower edge of the water-containing body 3 at the center position of the water-containing body 3 in the left-right direction. ing. This facilitates breathing through the mouth of the wearer when wearing the mask 1. In addition, by aligning the ventilation hole 30 of the water-containing body 3 with the ventilation hole 9 of the housing part 6, the water-containing body 3 can be held at a predetermined position in the housing part 6, and the water-containing body 3 can be stored without making a mistake in its orientation. It can be accommodated in section 6.

Furthermore, since the ventilation hole 30 extends in the vertical direction at the center position in the width direction of the water-containing body 3, the water-containing body 3 can be easily folded along the ventilation hole 30 at the center position in the left-right direction. In order to impregnate the water-containing body 3 with a large amount of water, as described above, it is necessary to increase the basis weight of the water-containing body 3. However, as the basis weight increases, the water-containing body 3 becomes hard, and when the mask 1 is worn, the water-containing body 3 becomes hard. 3 does not conform to the shape of the wearer's mouth and face, so the wearer may feel uncomfortable. However, if the ventilation hole 30 makes it easier for the water-containing body 3 to bend at the center position in the width direction, even if the basis weight of the water-containing body 3 is large, the water-containing body 3 will be able to follow the shape of the face around the wearer's mouth when wearing the mask 1. The wearer will not feel uncomfortable because the wearer will be able to deform the wearer.

In addition, the water-containing body 3 may be provided with one or more ventilation holes 30 including, for example, small-diameter holes, in addition to the positions corresponding to the ventilation holes 9 of the accommodating portion 6 . Furthermore, the water-containing body 3 does not necessarily need to be provided with the ventilation hole 30 at a position corresponding to the ventilation hole 9 of the housing section 6 . For example, the water-containing bodies 3 may be accommodated in the areas on the right and left sides of the ventilation hole 9 of the housing part 6, respectively, and each water-containing body 3 may be provided with a desired ventilation hole 30, or the ventilation hole 30 may not be provided. good.

The water-containing body 3 can be formed of various fiber materials, and 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, and pulp, with pulp being preferred from the viewpoint of flexibility and water retention. The method for manufacturing such a water-containing body 3 is not particularly limited, but it can be manufactured by an air-laid method, etc., and from the viewpoint of productivity, processability, and durability, heat-fused material such as polyethylene is added to pulp as the main component. It is preferable to blend the adhesive fibers in a predetermined ratio.

For example, when the water-containing body 3 is formed from pulp, the ratio of pulp to heat-fusible fiber is 60:40 to 80:20. The water-containing body 3 can have a single-layer or multi-layer structure, but from the viewpoint of durability and water retention, it is preferably 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 nonwoven fabrics is called the middle layer, and the layer consisting of the pair of nonwoven fabrics is called the both end layers. The nonwoven fabrics of both end layers may be made of the same material or may be made of different materials. Examples of the 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. Rayon is preferred. Hydrophilicity has the advantage that water can be easily absorbed into the pulp during production, making production easier. Examples of the hydrophobic fiber include polyesters such as polyethylene, polypropylene, and polyethylene terephthalate, with polyethylene and polypropylene being preferred. Hydrophobicity 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. 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 water-containing body 3 is impregnated may be only water, but water may be the main component and a polyol may be blended with the water. Examples of polyols include glycerin, dipropylene glycol, 1,3-butylene glycol, propylene glycol, sorbitol, 1,2 pentanediol, 1,2-hexanediol, and among them, glycerin is preferred in terms of safety. .
