Japanese Unexamined Patent Publication No. 2009-11475 Japanese Patent Publication No. 2006-525823

Transparent films have lower breathability than woven or non-woven fabrics. Therefore, when a soft (low rigidity) transparent film is used, the film may adhere to the mouth, making it difficult to breathe. On the other hand, when a hard (highly rigid) film is used, the film is arranged away from the mouth, and the fit may be deteriorated. More specifically, the applicant's diligent research revealed that increasing the rigidity of the film caused the outer edge of the film to rise from the face and the outer edge of the film to bite into the face. When the outer edge of the film rises from the face, the position of the mask tends to shift due to the outer edge of the film hitting the hand or the like. In addition, if the outer edge of the film bites into the face, a feeling of strangeness when worn is likely to occur. There was room for improvement in the mask that covered the mouth with a transparent film.
The present invention has been made in view of the above problems, and provides a mask that makes it easy for the wearer to breathe and improves the fit to the face.

The mask hung in one aspect includes a vertical direction extending up and down in the wearing state, an intersecting direction orthogonal to the vertical direction, and a covering portion formed of a film having a light transmittance of 80% or more and covering the wearer's mouth. It has a support portion that supports the cover portion, and a hook portion that is connected to the support portion and is hung on the wearer's ear. The covering portion has an outer edge extending in the vertical direction at the end edge of the covering portion in the crossing direction. The support has a side support that covers at least a portion of the outer edge of the cover. The air permeability of the support portion is higher than the air permeability of the cover portion. The rigidity of the covering portion is higher than the rigidity of the supporting portion.

(1) Outline of Embodiment At least the following matters will be clarified by the description of this specification and the accompanying drawings.
The mask hung in one embodiment includes a vertical direction extending up and down in the worn state, an intersecting direction orthogonal to the vertical direction, and a covering portion formed of a film having a light transmittance of 80% or more and covering the wearer's mouth. It has a support portion that supports the cover portion, and a hook portion that is connected to the support portion and is hung on the wearer's ear. The covering portion has an outer edge extending in the vertical direction at the end edge of the covering portion in the crossing direction. The support has a side support that covers at least a portion of the outer edge of the cover. The air permeability of the support portion is higher than the air permeability of the cover portion. The rigidity of the covering portion is higher than the rigidity of the supporting portion. Since the rigidity of the cover portion is relatively high and it is easy to maintain its shape, it is possible to prevent the cover portion from unintentionally coming into close contact with the mouth by breathing, and it is easy for the wearer to breathe. Further, by covering the outer edge of the covering portion with the support portion having relatively low rigidity, the outer edge of the covering portion does not directly hit the face but hits through the support portion. Therefore, it is possible to suppress a sense of discomfort caused by the outer edge of the covering portion biting into the face. Further, even when the outer edge of the covering portion is lifted from the face, the support portion is flexibly deformed, so that the support portion can secure the adhesion to the face. Therefore, it is possible to suppress the displacement of the mask due to the outer edge of the covering portion hitting the hand or the like.

According to a preferred embodiment, a high-rigidity portion having a higher rigidity than the surroundings is provided extending in the vertical direction at the center of the covering portion in the crossing direction. According to this aspect, the shape of the center of the covering portion in the crossing direction can be maintained by the high-rigidity portion, and it is possible to prevent the covering portion from being deformed and coming into close contact with the mouth.

According to the preferred form, the support portion and the hook portion are made of the same material. According to this aspect, the hanging portion pulls the entire outer edge of the covering portion outward in the crossing direction via the support portion in the worn state (the state of being hung on the ear). At this time, the support portion and the hook portion are integrated, and the support portion and the hook portion can cooperate with each other to pull the outer edge of the cover portion and press it toward the face side. Therefore, it is possible to effectively suppress the floating of the outer edge of the covering portion.

According to a preferred embodiment, the upper end edge of the inner portion of the hanging portion is located above the upper end edge of the outer edge of the covering portion. The lower end edge of the inner portion of the hanging portion is located below the lower end edge of the outer edge of the covering portion. According to this aspect, the hooking portion pulls the upper end edge of the outer edge of the covering portion diagonally upward and the lower end edge of the outer edge of the covering portion diagonally downward. Therefore, it is possible to suppress deformation such that the upper end edge and the lower end edge of the outer edge of the covering portion come close to each other, and it is possible to suppress the outer edge of the covering portion from rising while being curved.

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

According to the preferred embodiment, the side support portion is provided on the skin surface side of the cover portion. According to this aspect, the outer portion of the covering portion is less likely to be directly touched by the skin, and a feeling of discomfort to the skin can be suppressed.

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

According to a preferred embodiment, the upper support portion is formed with an upper tack portion that shortens the length of the upper standing portion in the crossing direction. The length of the upper tack portion in the crossing direction becomes longer toward the side away from the upper joint portion. According to this aspect, in the state where the upper standing portion is upright, the length of the upper standing portion in the crossing direction becomes shorter toward the side away from the upper joint portion. Therefore, when the face is covered with the upright portion, the upper end portion of the mask (the upright 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.

According to a preferred embodiment, the support portion has a lower support portion that covers the lower end portion of the cover portion on the skin surface side of the cover portion. The lower support portion has a lower joint portion joined to the lower end portion of the cover portion and a lower portion extending upward from the lower joint portion and capable of standing upright with respect to the cover portion with the lower joint portion as a base point. It has an upright part. According to this aspect, the lower upright portion of the lower support portion can stand up on the wearer side with the lower joint portion as a base point at the time of wearing and cover the face. At this time, when the lower standing portion is deformed so as to return to its original position (so that the lower standing portion is closed), the lower standing portion moves toward the skin and upward with the lower end portion of the covering portion as a base point. The face can be covered by the lower standing portion so as to fill the gap between the lower end portion of the covering portion and the wearer's face.

According to a preferred embodiment, the lower upright portion is formed with a lower tack portion that shortens the length of the lower upright portion in the crossing direction. The length of the lower tack portion in the crossing 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 upright, the length of the lower upright portion in the crossing direction becomes shorter toward the side away from the lower joint portion. Therefore, when the face is covered with the lower standing portion, the lower end portion of the mask (the standing portion 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 the preferred form, the support portion is made of a stretchable base cloth. The base fabric is a woven fabric and a non-woven fabric, and is excellent in breathability, flexibility and touch. Further, since the support portion has elasticity, it is possible to improve the adhesion of the support portion to the face and the adhesion of the outer edge of the cover portion to the face. Since the support portion is made of a base cloth, it is possible to improve the touch 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 covering portion 10 is 300 μm or less and is relatively thin, there is no sense of discomfort when covering the face, and it is possible to prevent the covering portion 10 from rising and hitting a hand or the like. In addition, the thickness of the covering portion is 100 μm or more, and it is possible to give a certain rigidity, and it is possible to suppress a problem that the film adheres to the mouth and it becomes difficult to breathe.

(2) Mask according to the embodiment The mask according to the embodiment will be described below 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 the description of the drawings below, the same or similar parts are designated by the same or similar reference numerals. However, it should be noted that the drawings are schematic and the ratio of each dimension may differ from the actual one. Therefore, the specific dimensions, etc. should be determined in consideration of the following explanation. In addition, there may be a portion where the relationship and ratio of the dimensions of the drawings are different from each other. Here, the upper end edge and the lower end edge in the present invention are edges located outside the vertical direction X, and the upper end portion and the lower end portion are constant in the vertical direction including the edge located outside the vertical direction X. It is the part that occupies the range. Further, the outer edge in the present invention is an outer edge in the crossing direction Y, and the outer portion is a portion that occupies a certain range in the crossing direction including the outer edge in the crossing direction Y. The inner edge in the present invention is an inner edge in the crossing direction Y, and the inner portion is a portion that occupies a certain range in the crossing direction including the inner edge in the crossing direction Y.

1 to 5 are diagrams showing a configuration example of the mask 1 according to the 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 seen from the outer surface side (non-skin surface side) Z2 of the unfolded mask 1, and FIG. 3 is a perspective view seen from the inner surface side (skin surface side) Z1 of the unfolded mask 1. Is. FIG. 4 is a diagram showing a wearing state of the mask according to the embodiment. FIG. 5 is a cross-sectional view taken along the line AA shown in FIG. The mask 1 has 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 extending above and below the wearer's face, and a crossing direction Y extending to the left and right sides of the wearer's face.

The covering portion 10 is made of a film having a light transmittance of 80% or more. The covering portion 10 is configured to cover at least the wearer's mouth and may be configured to cover both the nose and the mouth. In the folded state, the covering portion 10 is folded about the main body crease FL10 extending along the vertical direction X at the center of the crossing direction Y of the covering portion 10. The main body crease FL10 is a fold that folds the cover portion 10 so that the inner surface sides of the cover portion 10 face each other. Therefore, the covering portion 10 is formed with a valley fold habit when viewed from the inner surface side Z1. In another embodiment, the cover portion is not composed of a single film, has a left half-side sheet and a right half-side sheet, and the left half-side sheet and the right half-side sheet are formed at the center of the cover portion 10 in the crossing direction Y. It may be joined. However, in the form in which the left half surface sheet and the right half surface sheet are joined, the joint portion is provided at the center of the crossing direction Y of the covering portion 10, and the visibility of the covering portion 10 is lowered. Therefore, preferably, the covering portion 10 may be composed of a single material continuous in the crossing direction Y. Furthermore, in another embodiment, the mask may be unfolded and unfolded prior to use. The covering portion 10 may be vacuum-formed. The covering portion 10 has a light transmittance of 80% or more and is substantially transparent. The light transmittance may be measured by a well-known method. For example, a color difference meter manufactured by Nippon Denshoku Industries Co., Ltd. or an equivalent one can be used for measurement in accordance with JIS K7375.

The covering portion 10 has an outer edge forming the outer shape of the covering portion 10. The outer edges are a pair of outer edges 11 extending in the vertical direction X at the end edge of the covering portion 10 in the crossing direction Y, an upper end edge 12 extending in the crossing direction Y at the upper end of the covering portion 10, and an intersecting direction at the lower end of the covering portion 10. It has a lower end edge 13 extending to Y. In the present embodiment, the form extending in one direction is a concept including not only a configuration parallel to one direction but also a configuration of less than 45 degrees with respect to one direction.

The support portion 20 supports the cover portion 10. The support portion 20 has a side support portion 21 that covers at least a part of the outer edge 11 of the cover portion 10 in the vertical direction X. By covering at least a part of the outer edge 11 of the covering portion 10 with the side support portion 21, it is possible to prevent the outer edge 11 of the covering portion 10 from biting into the face. Preferably, the side support portion 21 may cover the entire outer edge 11 of the covering portion 10. According to this configuration, it is possible to prevent the outer edge 11 from biting into the face over the entire area of the outer edge 11 of the covering portion 10. In the case where the outer edge 11 is continuous in the vertical direction X from the upper end edge 111 of the outer edge 11 to the lower end edge 112 of the outer edge 11 as in the present embodiment, the side support portion 21 is also up and down. It may be continuous in the direction X. In another embodiment, when the outer edge 11 of the covering portion 10 is separated in the vertical direction X, the side support portion 21 may also be provided separately in the vertical direction X. The support portion 20 and the cover portion 10 are joined to each other by sewing, ultrasonic waves, heat sealing, and at least a part of an adhesive. In the joint portion of the present embodiment, the support portion 20 and the cover portion 10 are joined by a heat seal, and the joint portion 15 by the heat seal is shown in FIGS. 1 and 2. The joint portion 15 is provided along the outer edge of the covering portion and one round inward from the outer edge. Further, the joint portion 15 is formed along the lower end edge of the upper joint portion 221 described later.

As shown in FIG. 1, the hanging portion 30 is connected to the support portion 20 and is hung on the wearer's ear. The hooking portions 30 are connected to both sides of the support portion 20 in the crossing direction Y. Each hook 30 is hooked behind the wearer's ear. The inner portion 33 of the hook portion 30 is connected to the outer portion of the support portion 20. The inner portion 33 of the hooking portion 30 may be continuous in the vertical direction between the upper end edge 31 of the inner portion 33 and the lower end edge 32 of the inner portion 33, or the upper end edge 31 of the inner portion 33 and the lower end of the inner portion 33. The edges 32 may be separated and connected to the support portion 20 respectively. The outer portion 34 of the hook portion 30 is configured to be hooked behind the wearer's ear. With both of the pair of hooking portions 30 being hung on the ears, the outer portion of the covering portion 10 and the supporting portion 20 were pulled to the outside in the crossing direction Y, and the covering portion 10 covered the wearer's mouth. The state is maintained. The hooking portion 30 may be formed of a sheet member made of a non-woven fabric or the like, and may be formed of a notch 35 formed in the sheet member, or may be formed of a string-shaped elastic member.

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

The rigidity of the covering portion 10 is higher than the rigidity of the supporting portion 20. Since the rigidity of the covering portion 10 is relatively high and it is easy to maintain its shape, it is possible to prevent the covering portion 10 from unintentionally coming into close contact with the mouth by breathing, and it is easy for the wearer to breathe. Further, by covering the entire outer edge 11 of the covering portion 10 with the supporting portion 20 having relatively low rigidity, the outer edge 11 of the covering portion 10 does not directly hit the face but hits through the supporting portion 20. Therefore, it is possible to suppress a sense of discomfort caused by the outer edge 11 of the covering portion 10 biting into the face. Further, even when the outer edge 11 of the covering portion 10 is lifted from the face, the support portion 20 is flexibly deformed, so that the support portion 20 can secure the adhesion to the face. Therefore, it is possible to suppress the misalignment of the mask 1 due to the outer edge of the covering portion 10 hitting the hand or the like. In addition, a wearer who performs sign language, such as a hearing-impaired person, performs an action of putting a hand around the face, such as a action of putting a hand on the cheek in the sign language. At this time, since the outer edge 11 of the covering portion 10 has high adhesion, it is possible to suppress a problem that the sign language operation is hindered or that the operation of correcting the misalignment of the mask 1 is erroneously recognized as the sign language operation.

The thickness of the covering portion 10 may be 100 μm or more and 300 μm or less. Since the thickness of the covering portion 10 is 300 μm or less and is relatively thin, there is no sense of discomfort when covering the face, and it is possible to prevent the covering portion 10 from rising and hitting a hand or the like. Further, the thickness of the covering portion 10 is 100 μm or more, and it is possible to give a certain rigidity, and it is possible to suppress a problem that the film adheres to the mouth and it becomes difficult to breathe.

At the center of the crossing direction Y of the covering portion 10, a high-rigidity portion having higher rigidity than the surroundings may be provided extending in the vertical direction X. According to this aspect, the shape of the center of the crossing direction Y of the covering portion 10 can be maintained by the high-rigidity portion, and the covering portion 10 can be prevented from being deformed and coming into close contact with the mouth. The high-rigidity portion of the present embodiment is configured by the main body crease FL10. Further, in another embodiment, the high-rigidity portion may be formed by the joint portion in which the films constituting the cover portion 10 are joined to each other. However, in order to ensure the visibility of the covering portion 10, it is preferable that the joining portion is not provided at the center of the covering portion 10 in the crossing direction Y.

The support portion 20 and the hanging 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 separate materials, but are continuously formed of the same material. The hooking portion 30 pulls the entire outer edge 11 of the covering portion 10 to the outside in the crossing direction Y via the support portion 20 in the worn state. At this time, since the support portion 20 and the hook portion 30 are integrated, the support portion 20 and the hook portion 30 can cooperate with each other to pull the outer edge 11 of the cover portion 10 and press it toward the face side. Therefore, it is possible to suppress the floating of the outer edge 11 of the covering portion 10. Further, the support portion 20 covers the entire area of the outer edge 11 of the cover portion 10 in the vertical direction X, and the hook portion 30 has the upper end edge 111 and the lower end edge of the outer edge 11 of the cover portion 10 via the support portion 20. 112 (see FIG. 1) can be pulled in the crossing direction Y. For example, when the hooking portion 30 and the supporting portion 20 are composed of separate members and the hanging portion 30 is connected to the upper end edge and the lower end edge of the support portion 20, the hooking portion 30 has the upper end edge and the lower end edge of the support portion 20. The edges are pulled in the crossing direction Y, and the upper end edge and the lower end edge of the support portion 20 are pulled in a direction approaching each other (inside in the vertical direction). As a result, the upper end edge 111 and the lower end edge 112 of the outer edge 11 of the covering portion 10 are deformed so as to come close to each other, and the outer edge 11 of the covering portion 10 may be curved and lifted. More specifically, when the upper end edge 111 and the lower end edge 112 of the outer edge 11 of the covering portion 10 are deformed so as to approach each other, the center of the outer edge 11 of the covering portion 10 in the vertical direction X is curved so as to rise, and the covering portion 10 is formed. The outer edge 11 of the is easily lifted from the face. In particular, the covering portion 10 made of a film tends to be in a curved state, and it is easy to maintain a state in which the outer edge 11 is raised with respect to the cheek. However, since the support portion 20 and the hanging portion 30 are made of the same material, it is possible to press the entire outer edge 11 of the covering portion 10 toward the face side and prevent the outer edge 11 from rising while being curved. In another embodiment, the support portion 20 and the hook portion 30 may be made of different materials and may be joined to each other and connected to each other.

The upper end edge 31 of the inner portion 33 of the hanging portion 30 is located above the upper end edge 111 of the outer edge 11 of the covering portion 10, and the lower end edge 32 of the inner portion 33 of the hanging portion 30 is the outer edge of the covering portion 10. It may be located below the lower end edge 112 of 11. Since the upper end edge 31 of the inner portion 33 of the hanging portion 30 is located above the upper end edge 111 of the outer edge 11 of the covering portion 10, the hanging portion 30 is placed on the covering portion 10 while the hanging portion 30 is hung on the ear. Pull the upper edge 111 of the ears diagonally upward. Further, since the lower end edge 32 of the inner portion 33 of the hanging portion 30 is located below the lower end edge 112 of the outer edge 11 of the covering portion 10, the covering portion 10 is in a state where the hanging portion 30 is hung on the ear. Pull the lower edge 112 diagonally downward. Therefore, the upper end edge 111 and the lower end edge 112 of the outer edge 11 of the covering portion 10 are pulled in a direction away from each other. By suppressing deformation such that the upper end edge 111 and the lower end edge 112 of the outer edge 11 of the covering portion 10 approach each other, it is possible to prevent the outer edge 11 of the covering portion 10 from rising while being curved, and the outer edge of the covering portion 10 can be suppressed. 11 can be placed closer to the face.

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

The side support portion 21 may be provided on the skin surface side Z1 of the cover portion 10. According to this configuration, the outer portion of the covering portion 10 is less likely to come into direct contact with the skin, and a feeling of discomfort with the skin can be suppressed. Further, in another embodiment, the side support portion 21 may be arranged on both the skin surface side Z1 of the covering portion 10 and the non-skin surface side Z2 of the covering portion 10. That is, the outer edge 11 of the covering portion 10 may be sandwiched by the side support portion 21 in the thickness direction. According to the other embodiment, the outer edge 11 of the covering portion 10 can be pressed toward the face by the side supporting portion 21 located on the non-skin surface side, and the covering portion 10 can be pressed by the side supporting portion 21 located on the skin surface side Z1. It is possible to prevent the outer edge 11 of the face from directly hitting the face.

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

The upper upright portion 222 may be folded back so as to stand up against the upper joint portion 221 in the folded state shown in FIG. According to this embodiment, the fold habit of the folded state makes it easy for the upright portion 222 to stand up naturally, and the upper part of the wearer's face (for example, the nose) can be covered by the upright portion 222 when worn. Further, in another embodiment, the upper support portion 22 may be formed with an upper tack portion that shortens the length of the upper standing portion 222 in the crossing direction Y. The length of the upper tack portion in the crossing direction Y (the length obtained by picking the upper standing portion 222 in order to shorten the length of the upper standing portion 222 in the crossing direction Y) is toward the side away from the upper joint portion 221. It can be long. With the upper standing portion 222 standing upright, the length of the upper standing portion 222 in the crossing direction Y becomes shorter toward the side away from the upper joining portion 221. Therefore, when the face is covered with the upright portion 222, the upper end portion of the mask (the upright 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, in the form having the upper tack portion, the upper tack portion may be provided on the skin surface side of the upper standing portion 222.
