Japanese Patent Application Publication No. 2009-11475 Special Publication No. 2006-525823

Transparent films have lower air permeability than woven or nonwoven fabrics. Therefore, when a soft (low rigidity) transparent film is used, the film may come into close contact with the mouth, making it difficult to breathe. On the other hand, when a hard (highly rigid) film is used, the film may be placed away from the mouth, resulting in poor fit. More specifically, the applicant conducted intensive research and found that increasing the rigidity of the film causes the outer edge of the film to lift away from the face or to dig into the face. If the outer edge of the film lifts up from the face, the outer edge of the film will come into contact with your hands, etc., making it easy for the mask to become misaligned. Moreover, if the outer edge of the film digs into the face, it is likely to cause discomfort when worn. There is room for improvement in masks that cover the mouth with a transparent film.

The present invention has been made in view of the above problems, and provides a mask that allows the wearer to breathe easily and improves the fit to the face.

The mask according to one embodiment includes a vertical direction that extends vertically when worn, a cross direction orthogonal to the vertical direction, and a covering portion that covers the wearer's mouth and is made of a film having a light transmittance of 80% or more. , a support part that supports the cover part, and a hook part connected to the support part and hung on the ear of the wearer. The cover portion has an outer edge extending in the vertical direction at an end edge of the cover portion in the cross direction. The support portion has a side support portion that covers at least a portion of the outer edge of the cover portion. The air permeability of the support part is higher than the air permeability of the cover part. The rigidity of the cover part is higher than the rigidity of the support part.

(1) Overview of the embodiments At least the following points will become clear from the description of this specification and the accompanying drawings.
The mask according to one embodiment includes a vertical direction that extends vertically when worn, a cross direction orthogonal to the vertical direction, and a covering portion that covers the wearer's mouth and is made of a film having a light transmittance of 80% or more. , a support part that supports the cover part, and a hook part connected to the support part and hung on the ear of the wearer. The cover portion has an outer edge extending in the vertical direction at an end edge of the cover portion in the cross direction. The support portion has a side support portion that covers at least a portion of the outer edge of the cover portion. The air permeability of the support part is higher than the air permeability of the cover part. The rigidity of the cover part is higher than the rigidity of the support part. Since the cover has relatively high rigidity and can easily maintain its shape, the cover is prevented from unintentionally coming into close contact with the mouth due to breathing, making it easier for the wearer to breathe. Furthermore, by covering the outer edge of the covering part with the supporting part having relatively low rigidity, the outer edge of the covering part does not hit the face directly, but rather through the supporting part. Therefore, it is possible to suppress the discomfort caused by the outer edge of the covering portion digging into the face. Furthermore, even if the outer edge of the covering part is lifted off the face, the supporting part can flexibly deform and maintain close contact with the face. Therefore, it is possible to suppress misalignment of the mask due to the outer edge of the covering portion hitting a hand or the like.

According to a preferred embodiment, a high-rigidity portion having higher rigidity than the surrounding area is provided at the center of the cover portion in the cross direction and extends in the up-down direction. According to this aspect, the shape of the center of the cover part in the cross direction can be maintained by the high-rigidity part, and the cover part can be prevented from deforming and coming into close contact with the mouth.

According to a preferred form, the support part and the hook part are made of the same material. According to this aspect, the hook portion pulls the entire outer edge of the cover portion outward in the cross direction via the support portion when the cover portion is worn (hanged over the ear). At this time, the support part and the catch part are integrated, and the support part and the catch part can work together to pull the outer edge of the cover part and press it toward the face. Therefore, lifting of the outer edge of the cover can be effectively suppressed.

According to a preferred embodiment, the upper edge of the inner side of the hook is located above the upper edge of the outer edge of the cover. The lower end edge of the inner side of the hook part is located below the lower end edge of the outer edge of the cover part. According to this aspect, the hook part pulls the upper edge of the outer edge of the cover part diagonally upward and also pulls the lower edge of the outer edge of the cover part diagonally downward. Therefore, it is possible to suppress deformation in which the upper and lower edges of the outer edge of the cover portion approach each other, and to suppress the outer edge of the cover portion from curving and lifting up.

According to a preferred form, the side support portion is provided continuously over the entire area of the outer edge of the cover portion from the upper edge to the lower edge of the outer edge. According to this aspect, by covering the entire area of the outer edge of the cover part with the continuous support part, force can be applied evenly to the entire area of the outer edge of the cover part, and partial lifting can be suppressed.

According to a preferred form, the side support portion is provided on the skin side of the cover portion. According to this aspect, the outer part of the covering part is less likely to come into direct contact with the skin, and discomfort against the skin can be suppressed.

According to a preferred embodiment, the support section includes an upper support section that covers the upper end of the cover section on the skin side of the cover section. The upper support part includes an upper joint part joined to the upper end part of the cover part, and extends downward from the upper joint part, and stands up with respect to the cover part from a lower end edge of the upper joint part. and a possible upper standing portion. According to this aspect, the upper upright part of the upper support part can be raised toward the wearer's side from the upper joint part as a base point when worn, and can cover the face. At this time, when the upper upright part is deformed so as to return to its original state (so that the upper upright part closes), the upper upright part moves toward the skin side and downward from the upper end of the covering part as a base point. The face can be covered by the upper standing part so as to fill the gap between the upper end of the covering part and the wearer's face.

According to a preferred embodiment, the upper supporting portion is formed with an upper tuck portion that shortens the length of the upper standing portion in the cross direction. The length of the upper tuck portion in the cross direction becomes longer toward the side away from the upper joint portion. According to this aspect, in the state where the upper upright portion is erected, the length of the upper upright portion in the cross direction becomes shorter toward the side away from the upper joint portion. Therefore, when the face is covered by the upper standing part, the upper end part of the mask (the upper standing part in the standing state) can be easily brought into close contact with the face, and the gap between the face and the mask can be reduced.

According to a preferred embodiment, the support section includes a lower support section that covers a lower end of the cover section on the skin side of the cover section. The lower support part includes a lower joint part joined to the lower end part of the cover part, and a lower part that extends from the lower joint part to the upper side and can stand up with respect to the cover part from the lower joint part. It has a standing part. According to this aspect, the lower upright part of the lower support part is erected toward the wearer side from the lower joint part as a base point when worn, and can cover the face. At this time, when the lower upright part is deformed so as to return to its original state (so that the lower upright part closes), the lower upright part moves toward the skin and upward using the lower end of the cover as a base point. The face can be covered by the lower standing part so as to fill the gap between the lower end of the covering part and the wearer's face.

According to a preferred embodiment, the lower upright portion is formed with a lower tuck portion that shortens the length of the lower upright portion in the cross direction. The length of the lower tuck portion in the cross direction becomes longer toward the side away from the lower joint portion. According to this aspect, in the state where the lower upright portion is in an upright state, the length of the lower upright portion in the cross direction becomes shorter toward the side away from the lower joint portion. Therefore, when the lower standing portion covers the face, the lower end portion of the mask (lower standing portion in an upright state) can be easily brought into close contact with the face, and the gap between the face and the mask can be reduced.

According to a preferred embodiment, the support portion is made of a stretchable base fabric. The base fabric is a woven fabric or a nonwoven fabric, and has excellent breathability, flexibility, and feel. Furthermore, since the support part has elasticity, it is possible to improve the adhesion of the support part to the face and the adhesion of the outer edge of the cover part to the face. Since the support portion is made of base fabric, it is possible to improve the feel and ensure breathability.

According to a preferred embodiment, the thickness of the covering portion is 100 μm or more and 300 μm or less. Since the thickness of the cover part 10 is 300 μm or less and is relatively thin, it does not cause discomfort when covering the face, and can prevent it from rising up and hitting the hands or the like. In addition, the thickness of the covering portion is 100 μm or more, which allows it to have a certain degree of rigidity, and prevents the film from coming into close contact with the mouth and making it difficult to breathe.

(2) Mask according to the embodiment Hereinafter, a mask according to the embodiment will be described with reference to the drawings. The mask may be a disposable mask intended for one-time use, or may be a mask that can be used multiple times. In addition, in the description of the following drawings, the same or similar parts are given the same or similar symbols. However, it should be noted that the drawings are schematic and the ratio of each dimension may differ from the actual one. Therefore, specific dimensions etc. should be determined with reference to the following explanation. Furthermore, the drawings may include portions with different dimensional relationships and ratios. Here, the upper end edge and the lower end edge in the present invention are edges located on the outside in the up-down direction This is the part that occupies the range. Further, the outer edge in the present invention is the outer edge in the cross direction Y, and the outer portion is a part that occupies a certain range in the cross direction including the outer edge in the cross direction Y. The inner edge in the present invention is the inner edge in the cross direction Y, and the inner part is a part that occupies a certain range in the cross direction including the inner edge in the cross direction Y.

1 to 5 are diagrams showing configuration examples of a mask 1 according to an embodiment. FIG. 1 is a side view of a mask in a folded state in which the mask is folded in half. FIG. 2 is a perspective view of the mask 1 in the unfolded state as seen from the outer surface side (non-skin side) Z2, and FIG. 3 is a perspective view of the mask 1 in the unfolded state as seen from the inner surface side (skin surface side) Z1. It is. FIG. 4 is a diagram showing a state in which the mask according to the embodiment is worn. FIG. 5 is a cross-sectional view taken along line AA shown in FIG. The mask 1 includes a cover portion 10 that covers at least the wearer's mouth, a pair of support portions 20, and a pair of hook portions 30. The mask 1 has a vertical direction X that extends above and below the wearer's face, and a cross direction Y that extends to the left and right sides of the wearer's face.

The cover portion 10 is made of a film having a light transmittance of 80% or more. The cover 10 is configured to cover at least the wearer's mouth, and may be configured to cover both the nose and mouth. In the folded state, the cover part 10 is folded with a main body crease FL10 extending along the up-down direction X at the center of the cover part 10 in the intersecting direction Y as a base point. The main body fold line FL10 is a fold line by which the cover part 10 is folded so that the inner surfaces of the cover part 10 face each other. Therefore, the cover portion 10 has a valley fold when viewed from the inner surface side Z1. In another embodiment, the covering part is not constituted by a single film, but has a left half sheet and a right half sheet, and the left half sheet and the right half sheet are arranged at the center of the covering part 10 in the intersecting direction Y. They may be joined. However, in the configuration in which the left half sheet and the right half sheet are joined, the joint portion is provided at the center of the cover portion 10 in the intersecting direction Y, and the visibility of the cover portion 10 is reduced. Therefore, preferably, the cover portion 10 may be made of a single material that is continuous in the cross direction Y. Additionally, in another embodiment, the mask may be unfolded rather than folded prior to use. The cover portion 10 may be vacuum formed. The cover portion 10 has a light transmittance of 80% or more and is substantially transparent. Note that the light transmittance may be measured by a known method. For example, it can be measured in accordance with JIS K 7375 using a colorimeter made by Nippon Denshoku Kogyo Co., Ltd. or a device equivalent thereto.

The cover part 10 has an outer edge that forms the outer shape of the cover part 10. The outer edges include a pair of outer edges 11 extending in the vertical direction It has a lower edge 13 extending in the Y direction. Note that in this embodiment, the term "extending in one direction" includes not only a configuration parallel to one direction but also a configuration at an angle of less than 45 degrees to one direction.

The support section 20 supports the cover section 10. The support portion 20 has a side support portion 21 that covers at least a portion of the outer edge 11 of the cover portion 10 in the vertical direction X. By covering at least a portion of the outer edge 11 of the cover part 10 with the side support part 21, it is possible to suppress the outer edge 11 of the cover part 10 from digging into the face. Preferably, the side support 21 may cover the entire outer edge 11 of the cover 10. According to this configuration, it is possible to suppress the outer edge 11 from digging into the face over the entire area of the outer edge 11 of the cover part 10. Note that, in a configuration in which the outer edge 11 is continuous in the vertical direction May be continuous in direction X. In another embodiment, if the outer edge 11 of the cover portion 10 is separated in the vertical direction X, the side support portions 21 may also be provided separated in the vertical direction X. The support portion 20 and the cover portion 10 are joined to each other by at least some of sewing, ultrasound, heat sealing, and adhesive. In the joint portion of this embodiment, the support portion 20 and the cover portion 10 are joined by heat sealing, and the joint portion 15 formed by heat sealing is shown in FIGS. 1 and 2. The joint portion 15 is provided along the outer edge of the cover portion, one size more inside than the outer edge. Further, the joint portion 15 is formed along the lower edge of an upper joint portion 221, which will be described later.

As shown in FIG. 1, the hook part 30 is connected to the support part 20 and is hung on the wearer's ear. The hook portions 30 are continuous with both sides of the support portion 20 in the cross direction Y. Each hook 30 is hooked behind the wearer's ear. The inner part 33 of the hook part 30 is continuous with the outer part of the support part 20. The inner part 33 of the hook part 30 may be continuous in the vertical direction between the upper edge 31 of the inner part 33 and the lower edge 32 of the inner part 33, or the upper edge 31 of the inner part 33 and the lower end of the inner part 33. The edges 32 may be spaced apart and each connected to the support portion 20. The outer portion 34 of the hook 30 is configured to hook behind the wearer's ear. When both of the pair of hanging parts 30 are worn over the ears, the outer part of the cover part 10 and the support part 20 are pulled outward in the cross direction Y, and the cover part 10 covers the wearer's mouth. The state is maintained. The hanging portion 30 may be formed by a sheet member made of nonwoven fabric or the like, and may be formed by a cut 35 formed in the sheet member, or may be formed by a string-like elastic member.

The mask of this embodiment is configured to allow the wearer to breathe easily and to improve the fit to the face. Next, a configuration that allows the wearer to breathe easily and improves the fit to the face will be described in detail. The air permeability of the support part 20 is higher than that of the cover part 10. The cover portion 10 is made of a film, and its breathability is relatively low. The support portion 20 is made of, for example, nonwoven fabric, woven fabric, or urethane, and has relatively high air permeability. Therefore, even if the mouth is covered with the cover part 10 made of a film, breathability can be ensured through the support part 20 that supports the cover part, and the wearer's breathing can be ensured.

The rigidity of the cover part 10 is higher than the rigidity of the support part 20. Since the cover part 10 has relatively high rigidity and can easily maintain its shape, the cover part 10 is prevented from unintentionally coming into close contact with the mouth due to breathing, making it easier for the wearer to breathe. Moreover, by covering the entire outer edge 11 of the cover part 10 with the support part 20 having relatively low rigidity, the outer edge 11 of the cover part 10 does not hit the face directly, but does so through the support part 20. Therefore, the discomfort caused by the outer edge 11 of the covering part 10 digging into the face can be suppressed. Moreover, even if the outer edge 11 of the covering part 10 is lifted from the face, the support part 20 can be flexibly deformed, so that the support part 20 can ensure close contact with the face. Therefore, it is possible to suppress the positional shift of the mask M caused by the outer edge of the cover part 10 hitting a hand or the like. In addition, a wearer who practices sign language, such as a hearing-impaired person, performs an action of placing their hand around their face, such as an action of placing their hand on their cheek, in sign language. At this time, since the outer edge 11 of the cover part 10 has high adhesion, it is possible to suppress problems such as interference with the sign language movement or erroneous recognition that the movement of correcting the misalignment of the mask 1 is a sign language movement.

The thickness of the cover portion 10 may be 100 μm or more and 300 μm or less. Since the thickness of the cover part 10 is 300 μm or less and is relatively thin, it does not cause discomfort when covering the face, and can prevent it from rising up and hitting the hands or the like. In addition, the thickness of the cover portion 10 is 100 μm or more, so that it can have a certain degree of rigidity, and it is possible to prevent the film from coming into close contact with the mouth and making it difficult to breathe.

A high-rigidity part having higher rigidity than the surrounding area may be provided at the center of the cover part 10 in the cross direction Y so as to extend in the vertical direction X. According to this aspect, the shape of the center of the cover part 10 in the cross direction Y can be maintained by the high-rigidity part, and it is possible to suppress the cover part 10 from deforming and coming into close contact with the mouth. The high rigidity portion of this embodiment is constituted by the main body fold line FL10. Furthermore, in another embodiment, the high-rigidity portion may be configured by a bonded portion where the films forming the cover portion 10 are bonded to each other. However, in order to ensure the visibility of the cover part 10, it is preferable that no joining part is provided at the center of the cover part 10 in the cross direction Y.

The support portion 20 and the hook portion 30 may be made of the same material. That is, the support portion 20 and the hook portion 30 are not formed by joining different materials, but are continuously formed from the same material. The hook portion 30 pulls the entire outer edge 11 of the cover portion 10 outward in the cross direction Y via the support portion 20 in the worn state. At this time, since the support part 20 and the catch part 30 are integrated, the support part 20 and the catch part 30 can work together to pull the outer edge 11 of the cover part 10 and press it toward the face. Therefore, lifting of the outer edge 11 of the cover portion 10 can be suppressed. Further, the support portion 20 covers the entire area of the outer edge 11 of the cover portion 10 in the vertical direction 112 (see FIG. 1) can be pulled in the cross direction Y. For example, if the hook portion 30 and the support portion 20 are configured as separate members, and the hook portion 30 is connected to the upper edge and the lower edge of the support portion 20, respectively, the hook portion 30 is connected to the upper edge and the lower edge of the support portion 20. The edges are pulled in the cross direction Y, and the upper and lower edges of the support section 20 are pulled in a direction toward each other (inward in the vertical direction). As a result, the upper edge 111 and the lower edge 112 of the outer edge 11 of the cover part 10 are deformed so as to approach each other, and the outer edge 11 of the cover part 10 may curve and rise. More specifically, when the upper edge 111 and lower edge 112 of the outer edge 11 of the cover part 10 are deformed so as to approach each other, the center of the outer edge 11 of the cover part 10 in the vertical direction The outer edge 11 of the face tends to stand out from the face. In particular, the covering portion 10 made of a film tends to be curved, and the outer edge 11 tends to maintain a raised state with respect to the cheek. However, since the support part 20 and the hanging part 30 are made of the same material, the entire outer edge 11 of the cover part 10 can be pressed toward the face, and the outer edge 11 can be prevented from curving and lifting. In addition, in another embodiment, the support part 20 and the hook part 30 may be made of different materials, and may be joined to each other so as to be continuous.

The upper edge 31 of the inner side 33 of the hook 30 is located above the upper edge 111 of the outer edge 11 of the cover 10, and the lower edge 32 of the inner side 33 of the hook 30 is located above the outer edge 11 of the cover 10. It may be located below the lower edge 112 of 11. Since the upper edge 31 of the inner side 33 of the hook 30 is located above the upper edge 111 of the outer edge 11 of the cover 10, when the hook 30 is hung on the ear, the hook 30 is placed on the cover 10. Pull the upper edge 111 diagonally upward. In addition, since the lower edge 32 of the inner side 33 of the hook 30 is located below the lower edge 112 of the outer edge 11 of the cover 10, the cover 10 can Pull the lower edge 112 diagonally downward. Therefore, the upper edge 111 and lower edge 112 of the outer edge 11 of the cover part 10 are pulled in the direction away from each other. By suppressing deformation in which the upper edge 111 and the lower edge 112 of the outer edge 11 of the cover part 10 approach each other, it is possible to suppress the outer edge 11 of the cover part 10 from curving and lifting up, and the outer edge of the cover part 10 11 can be placed closer to the face.

The side support portion 21 of the support portion 20 may be provided continuously from the upper edge 111 to the lower edge 112 of the outer edge 11 of the cover portion 10 . By covering the entire area of the outer edge 11 of the cover part 10 with the continuous side support part 21, force is applied evenly to the entire area of the outer edge 11 of the cover part 10, and the outer edge 11 of the cover part 10 is partially raised. can be suppressed.

The side support portion 21 may be provided on the skin side Z1 of the cover portion 10. According to this configuration, the outer part of the covering part 10 is less likely to come into direct contact with the skin, and discomfort against the skin can be suppressed. Moreover, in another embodiment, the side support part 21 may be arranged on both the skin side Z1 of the cover part 10 and the non-skin side Z2 of the cover part 10. That is, the outer edge 11 of the cover part 10 may be sandwiched between the side support parts 21 in the thickness direction. According to the other embodiment, the outer edge 11 of the cover part 10 can be pressed toward the face side by the side support part 21 located on the non-skin side, and the side support part 21 located on the skin side Z1 can press the outer edge 11 of the cover part 10 toward the face side. The outer edge 11 of the face can be prevented from coming into direct contact with the face.

The support part 20 may include an upper support part 22 that covers the upper end of the cover part 10 on the skin side Z1 of the cover part 10. The upper support part 22 may cover at least a portion of the upper end of the cover part. In this embodiment, the upper support portion 22 covers the entire upper end portion of the cover portion 10 and is continuous with the side support portion 21 . As shown in FIG. 4, the upper support portion 22 includes an upper joint portion 221 joined to the upper end portion of the cover portion 10, and extends downward from the upper joint portion 221, and covers the lower end edge of the upper joint portion 221 as a base point. It may have an upper standing part 222 that can stand up with respect to the part 10. The upper joint portion 221 in this embodiment is a region surrounded by two heat seals (joint portions 15), and is shown with diagonal lines in FIG. The upper upright portion 222 of the upper support portion 22 is erected toward the wearer from the upper joint portion 221 when worn, and can cover the wearer's face. At this time, when the upper upright part 222 is deformed so as to return to its original state (so that the upper upright part is closed), the upper upright part 222 moves toward the skin side and downward from the upper end of the covering part 10 as a base point. The face can be covered by the upper standing part 222 so as to fill the gap between the upper end of the cover part 10 and the wearer's face.

The upper standing portion 222 may be folded back so as to stand up with respect to the upper joint portion 221 in the folded state shown in FIG. According to this form, the upper standing part 222 tends to stand up naturally due to the folding tendency in the folded state, and the upper standing part 222 can cover the upper part of the wearer's face (for example, the nose) when worn. In another embodiment, the upper support portion 22 may be formed with an upper tuck portion that shortens the length of the upper standing portion 222 in the cross direction Y. The length of the upper tuck portion in the cross direction Y may increase toward the side away from the upper joint portion 221. In the state where the upper standing portion 222 stands up, the length of the upper standing portion 222 in the cross direction Y becomes shorter toward the side away from the upper joint portion 221. Therefore, when the face is covered by the upper standing portion 222, the upper end portion of the mask (the upper standing portion in the upright state) can be easily brought into close contact with the face, and the gap between the face and the mask can be reduced. Further, in the case of a configuration having an upper tuck portion, the upper tuck portion may be provided on the skin surface side of the upper standing portion 222. According to this configuration, when worn, the upper tuck part can be grasped to make the upper standing part 222 stand up with respect to the upper joint part 221. In another embodiment, the upper support portion 22 may include a nose fit member at a portion corresponding to the nose when worn. The mask 1 of this embodiment does not include an upper tuck portion and a nose fit member.

The support section 20 may include a lower support section 23 that covers the lower end of the cover section 10 on the skin side of the cover section 10 . The lower support portion 23 may cover at least a portion of the lower end portion of the cover portion 10. In this embodiment, the lower support portion 23 covers the entire lower end portion of the cover portion 10 and is continuous with the side support portion 21 . The lower support portion 23 includes a lower joint portion 231 joined to the lower end portion of the cover portion 10, and extends upward from the lower joint portion 231, and is capable of standing up with respect to the cover portion 10 from the upper end edge of the lower joint portion 231. A lower standing portion 232 may be included. The lower joint portion 231 of this embodiment is formed by one heat seal. The lower upright portion 232 of the lower support portion 23 is erected toward the wearer from the lower joint portion 231 when worn, and can cover the wearer's face. At this time, when the lower upright part 232 is deformed so as to return to its original state (so that the lower upright part is closed), the lower upright part 232 moves toward the skin and upward using the lower end of the covering part 10 as a base point. The face can be covered by the lower standing portion 232 so as to fill the gap between the lower end of the covering portion and the wearer's face.

A lower tuck portion 233 may be formed on the lower upright portion 232 to shorten the length of the lower upright portion 232 in the intersecting direction Y. The length of the lower tuck portion 233 in the cross direction Y increases toward the side away from the lower joint portion 231. Therefore, when the lower standing portion 232 covers the face, the upper end portion of the mask (lower standing portion in an upright state) can be easily brought into close contact with the face, and the gap between the face and the mask can be reduced. Further, the lower tuck portion 233 may be provided on the skin surface side Z1 of the lower standing portion 232. According to this configuration, when worn, the lower tuck portion 233 can be grasped to make the lower standing portion 232 stand up with respect to the lower joint portion 231. In another embodiment, the lower support portion 23 may include a nose fit member at a portion corresponding to the nose when worn. The mask 1 of this embodiment includes a lower tuck portion and does not include a nose fit member.

The support portion 20 may be made of a stretchable base fabric. Here, the base fabric is a nonwoven fabric or a woven fabric. Since the support portion is made of base fabric, it is possible to improve the feel and ensure breathability. Moreover, since the support part 20 has elasticity, it is possible to improve the adhesion of the support part to the face and the adhesion of the outer edge of the covering part to the face. Since the support portion 20 is made of base fabric, it is possible to improve the feel and ensure breathability.
