Japanese Unexamined Patent Publication No. 2018-204169 Utility Model Registration No. 3055534 Gazette

In a disposable mask without a pattern as in Patent Document 1, the inner surface (the surface that comes into contact with the skin when worn) and the outer surface (the surface opposite to the inner surface) are colored in the same color or a similar color as a whole. It becomes difficult to distinguish between the inner surface and the outer surface, and it may take time to attach the mask. In addition, the inner surface and the outer surface may be mistakenly attached, and the outer surface may be attached as a surface that comes into contact with the skin. In that case, the original function of the mask may not be exhibited. Further, in a disposable mask having a pattern as in Patent Document 2, it is not difficult to distinguish between the inner surface and the outer surface, but there is a risk that the mask performance may be affected or the cost may increase depending on the printing of the pattern.

An object of the present invention is to provide a disposable mask that can easily distinguish between an inner surface and an outer surface while suppressing the influence on the mask performance.

The disposable mask of the present invention has (1) a vertical direction, a width direction, and a thickness direction, has a first surface and a second surface which are one and the other surfaces in the thickness direction, and is made of a non-woven fabric. A disposable mask comprising a mask body and a pair of ear hook members fused to the second surface on both sides of the mask body in the width direction at a fused portion, wherein the color of the ear hook members is , A disposable mask in which a color different from the color of the first surface is visible from the first surface side through the fused portion, which is different from the color of the first surface of the mask body.

In this disposable mask, when the non-woven fabric of the mask body is fused with the ear hook member at the fused portion, it melts into a film and becomes substantially transparent. Therefore, the user can use the color of the ear hook member fused to the second surface, or the mixed color in which the color of the ear hook member and the color of the first surface and / or the second surface are mixed (hereinafter, simply). (Also referred to as “mixed color”) is configured to be visible from the first surface side via a substantially transparent fused portion. However, the color or mixed color of the ear hook member is different from the color of the first surface. Therefore, when the user views the disposable mask from the first surface side, the color different from that of the first surface, that is, the fused portion is seen through and grasped at the positions of the fused portions at both ends in the width direction. The color or mixed color of the ear hook member can be easily confirmed. Therefore, when the user looks at the first surface of the disposable mask, the color of the first surface and the color grasped through the fused portion are different, so that the user's line of sight is fused on the first surface side. It can be easily pointed at the landing part. As a result, it is easy for the user to know that the fused portion on the first surface side is not the fused portion on the second surface side to which the ear hook member is directly fused, and thus that surface is the first surface. It can be grasped. Conversely, when the user looks at the second surface of the disposable mask, since the ear hook member is directly fused, it can be easily grasped that the surface is the second surface. That is, the user can easily distinguish between the second surface and the first surface.
Here, the user knows in advance which of the first surface and the second surface is the inner surface and which is the outer surface in the drawing of the mask package or the like. Alternatively, the user can initially use the disposable mask once, even if he / she does not know which of the first and second surfaces is the inner surface and which is the outer surface, and then which is the inner surface. Yes, you can figure out which is the outer surface. Thereby, the user can easily distinguish between the first surface and the second surface, and thus the inner surface and the outer surface.
Further, since it is not necessary to provide a symbol on the first surface or the second surface in order to distinguish between the inner surface and the outer surface, it is possible to suppress the influence on the mask performance and the increase in cost.
Then, it is suppressed that it takes time to put on the disposable mask, the disposable mask can be put on correctly, and the disposable mask can correctly exert its original function.

The disposable mask of the present invention may be (2) the disposable mask according to (1) above, wherein the color of the ear hook member is similar to the color of the second surface of the mask body.
In this disposable mask, the color of the ear hook member is similar to the color of the second surface to which the ear hook member is fused. Therefore, when the user sees the first surface of the disposable mask, the color of the first surface and the color grasped through the fused portion are different, that is, the color of the first surface and the ear hook member. Since the colors or mixed colors of the above are not similar to each other, it can be immediately understood that the surface is not the second surface to which the ear hook member is directly fused. Conversely, when the user looks at the second surface of this disposable mask, the color of the second surface and the color of the fused portion (the color of the ear hook member itself is from the second surface side) are mutually exclusive. Since the colors are similar, it can be easily grasped that the surface is the second surface. That is, the user can easily distinguish between the second surface and the first surface. In this case, the similar colors include the same color.

In this disposable mask, the ear hook member is coupled to the outer surface side so as to press the mask body from the second surface, that is, the outer surface side toward the skin when worn. As a result, when the disposable mask is worn by the user, it can be properly fitted to the face and can correctly exert its original function. In addition, when the user looks at the first surface of the disposable mask, that is, the inner surface, the color of the inner surface and the color grasped through the fused portion are different, so that the surface is immediately the inner surface. I can grasp it. Conversely, when the user looks at the second surface, that is, the outer surface of the disposable mask, the ear hook member is directly fused, so that the surface can be immediately grasped as the outer surface. That is, the inner surface and the outer surface can be easily distinguished.

In the disposable mask of the present invention, (4) the color of the ear hook member and the color of the first surface of the mask body have a hue of 5 or more, a brightness of 1 or more, or a saturation in the Munsell color system.

Further, in the woven rubber, even if tension is applied in the length direction, the dimension in the width direction hardly changes and does not become thin. Therefore, the color of the woven rubber as the ear hook member can be easily grasped even when tension is applied in the length direction. They allow the inner and outer surfaces to be more easily distinguished by color.

In the disposable mask of the present invention, (6) the color of the warp and weft in the woven rubber, whichever has the larger number of threads per unit volume, is different from the color of the first surface of the mask body. It may be the disposable mask according to 5).
In this disposable mask, the color of the warp and weft, which has the larger number of threads per unit volume, is different from the color of the first surface of the mask body. It is possible to more easily distinguish between the two surfaces and the first surface where the color of the woven rubber can be visually recognized through the fused portion. Thereby, the inner surface and the outer surface can be more easily distinguished by the color.

In the disposable mask of the present invention, (7) the mask body has an extension portion in which at least one of the both ends in the vertical direction extends outward in the width direction at each of the both ends in the width direction.

The part is fused to the extended fusion part. In this way, by locating the extension fusion splicing portion in the extension portion extending in the outer direction in the width direction, the user can easily grasp the extension fusion splicing portion, so that the extension fusion splicing portion can be easily grasped. The color or mixed color of the ear hook member can be easily visually recognized from the first surface side. Therefore, the user can more easily distinguish between the second surface and the first surface. Thereby, the inner surface and the outer surface can be more easily distinguished by the color.

In the disposable mask of the present invention, (8) the extending portion is the first one in which one end portion in the vertical direction extends outward in the width direction at each of both ends in the width direction of the mask body. An extension portion, a second extension portion having the other end portion in the vertical direction extending in the outer direction in the width direction, and an extension portion between the first extension portion and the second extension portion. The constricted portion confined in the inner direction in the width direction is located, and the extension fusion splicing portion is located at the first extension fusion splicing portion located at the first extension portion and the second extension fusion splicing portion. The ear hook member includes a second extension fusion splicing portion, one end of which is fused by the first extension fusion splicing portion, and the other end portion of the mask by the second extension fusion splicing portion. The disposable mask according to (7) above, which is fused to the main body, may be used.
In this disposable mask, the mask body includes first and second extending portions having both ends in the vertical direction extending in the outward direction in the width direction at the end portions in the width direction, and the ear hook member is formed by the ear hook member. One end and the other end are fused to the first and second extension fusion splicing portions. In this way, by locating the first and second extension fusion splicers in the first and second extension portions extending in the outer direction in the width direction, the first and second extension fusion splicing portions can be formed. Since it can be easily grasped, the color or mixed color of the ear hook member can be easily visually recognized from the first surface side via the first and second extension fusion splicing portions. Therefore, the user can more easily distinguish between the second surface and the first surface. Thereby, the inner surface and the outer surface can be more easily distinguished by the color.

The disposable mask of the present invention has (9) any one of the above (1) to (8), wherein the fused portion is formed by melting the mask main body and the ear hook member with ultrasonic waves. It may be the disposable mask described in 1.
In this disposable mask, the fused portion is formed by melting the mask body and the ear hook member with ultrasonic waves, so that the non-woven fabric of the mask body can be easily formed into a film, whereby the second The color or mixed color of the ear hook member located on the surface can be easily made visible from the first surface side via the fused portion. Thereby, the inner surface and the outer surface can be more easily distinguished by the color.

In the disposable mask of the present invention, (10) the mask main body is a laminated body in which a plurality of non-woven fabrics are laminated, and the laminated body has a plurality of main body fusion portions for fusing the plurality of non-woven fabrics to each other.

It may be a disposable mask.
The disposable mask includes a character string that is legible when viewed from the second surface, and has a character string fusion portion that is asymmetric with respect to the center line. Thereby, the second surface and the first surface can be easily distinguished from the state of the character string in the character string fusion portion. Further, since the character string fusion portion is a fusion portion for fusing a plurality of nonwoven fabrics to each other, the character string fusion portion can be formed while suppressing the influence on the mask performance and the increase in cost. Thereby, the inner surface and the outer surface can be more easily distinguished by the color.

Further, the disposable mask of the present invention has a structure in which (11) the fused portion is formed by fusing the film portion formed by the mask body into a film and the end portion of the ear hook portion via a joint surface (11). The disposable mask according to any one of 1) to (10) may be used.

According to the present invention, it is possible to provide a disposable mask capable of easily distinguishing between an inner surface and an outer surface while suppressing the influence on the mask performance.

It is a perspective view which shows the structural example of the disposable mask which concerns on embodiment. It is a side view of the outer surface side which shows the structural example of the disposable mask which concerns on embodiment. It is a side view of the inner surface side which shows the structural example of the disposable mask which concerns on embodiment. It is a partial cross-sectional view of the disposable mask shown in FIG. It is a front view which shows the structural example of the disposable mask which concerns on other embodiment. It is a back view which shows the structural example of the disposable mask which concerns on other embodiment.

Hereinafter, the disposable mask according to the embodiment will be described with reference to the drawings.
1 to 4 are diagrams showing a configuration example of the disposable mask 1 (hereinafter, also simply referred to as “mask 1”) according to the embodiment. However, FIG. 1 is a perspective view showing an aspect of wearing the mask 1. FIG. 2 is a side view showing the outer surface of the mask 1 in a state where the mask 1 is folded in half. FIG. 3 is a side view showing the inner surface of the mask 1 in a state where the mask 1 is folded in half. FIG. 4A is a partial cross-sectional view taken along the line IVa-IVa in FIG. 2, and FIG. 4B is a partial cross-sectional view taken along the line IVb-IVb in FIG. The mask 1 is fused to a mask main body 10 made of a sheet-like member including a non-woven fabric that covers the wearer's mouth and nose by a fusing portion 30, and is hung on a pair of wearer's ears. It is provided with a pair of ear hook members 20 made of a string-shaped or band-shaped member.

The mask body 10 has a vertical direction L, a width direction W, and a thickness direction T, and has an inner surface IS (first surface) and an outer surface OS (second surface) which are one and the other surfaces in the thickness direction T. ). Here, in the vertical direction L, the fusion portion 30 for fusing one of the pair of ear hook members 20 and the mask body 10 and the fusion portion for fusing the other of the pair of ear hook members 20 with the mask body 10 are fused. When the mask body 10 is folded in half so that the portions 30 overlap with each other, it is the direction of the straight line formed by the folds. However, as in the present embodiment, when the crease forms a curve (FIG. 2), the vertical direction L is the top Ca in the curve, which is located at the uppermost position on the face when worn, and the lowermost position. The direction is the direction of the straight line CL connecting the top Cb to be located. The width direction W is orthogonal to the vertical direction L and is a direction along the outer surface OS or the inner surface IS. The thickness direction T is a direction orthogonal to the vertical direction L and the width direction W, and is therefore the direction of the thickness of the sheet constituting the mask body 10. The shape of the mask body 10 is not limited to the examples in these figures as long as it can cover the nose and mouth, and for example, a substantially elliptical shape, a substantially inverted triangular shape, a substantially polygonal shape, and the like. Combinations and the like can be mentioned.

The pair of ear hook members 20 are fused to the outer surface OS (second surface) on both sides of the mask body 10 in the width direction W by the fused portions 30 and 30. The fused portion 30 is formed, for example, by a method in which the ear hook member 20 and the mask body 10 are fused by heat or ultrasonic waves. When the mask body 10 is fused with the ear hook member 20 by the fusion portion 30, the portion corresponding to the fusion portion 30 of the mask body 10 is once melted to form a film-like film portion 15 (described later), and the film is formed. The portion 15 and the end portion 22 (described later) of the ear hook member 20 are fused. Therefore, the fused portion 30 includes the film portion 15 and the end portion 22, and both have a structure in which they are fused via the joint surface CS. In the joint surface CS, both may be partially mixed with each other. In another embodiment, the inner surface IS is the second surface and the outer surface OS is the first surface. In that case, the pair of ear hook members 20 are fused to the inner surfaces IS (second surface) of both side portions of the mask main body 10 in the width direction W by the fused portions 30 and 30. The end of a member or the like in a certain direction (example: vertical direction L, width direction W) is 1/5 of the total length of the member or the like in that direction from the edge in that direction. The range of dimensions. For example, the end portion of the mask body 10 in the width direction W means a range of a width of 1/5 of the maximum length of the mask body 10 in the width direction W from the edge of the mask body 10 in the width direction W.

In the fused portion 30, since the film portion 15 is substantially transparent, it is possible for a part or all of the light rays (eg, visible light rays) to pass through the inside. However, depending on the color of the outer surface OS and the color of the inner surface IS, the color of the film portion 15 may be a color including at least one of the color of the outer surface OS and the color of the inner surface IS. Therefore, when the film portion 15 is viewed from the inner surface IS side or the outer surface OS side, the colors of the members and the like (eg, the end portion 22 of the ear hook member 20) located in the vicinity of the outer surface OS side or the inner surface IS side on the opposite sides, respectively. Is visible. The fusion method, that is, the method for forming the fusion portion 30, is a method of fusion with ultrasonic waves from the viewpoint of ease of film formation of the film portion 15 in the mask body 10, ease of high-speed production, and reliability. Is preferable.

The color of the ear hook member 20 is different from the color of the inner surface IS (first surface) of the mask body 10. Therefore, the color of the ear hook member 20 (end 22) or the color of the ear hook member from the inner surface IS (first surface) side via the fused portion 30 (the film portion 15 of the mask body 10). A mixed color (also simply referred to as “mixed color”) in which the colors of the inner surface IS and / or the outer surface OS are mixed can be easily visually recognized. Therefore, when the user looks at the inner surface IS of the mask body 10, the color of the inner surface IS and the fusion portion 30 on the inner surface IS side (the film portion 15 of the mask body 10) can be seen through the outer surface OS side. It can be confirmed that the color or the mixed color of the ear hook member 20 (end 22) is different. Therefore, it is easy to distinguish between the inner surface IS and the outer surface OS to which the ear hook member 20 is directly attached. However, the color of the inner surface IS is preferably a white color. As a result, the color of the ear hook member 20 can be less affected by the color of the inner surface IS of the film portion 15, and can be easily visually recognized via the fused portion 30.
Further, in the present embodiment, the color of the inner surface IS of the mask body 10 is different from the color of the outer surface OS. This is to make it easier to distinguish between the inner surface IS and the outer surface OS. Further, in the present embodiment, the color of the ear hook member 20 is similar to or similar to the color of the outer surface OS of the mask body 10. As a result, the color of the ear hook member 20 in the fused portion 30 is emphasized by the color of the outer surface OS, so that the color of the inner surface IS of the film portion 15 can be less affected, and the color of the ear hook member 20 can be further reduced through the fused portion 30. It becomes easier to see. That is, the ear hook member 20, the outer surface OS, and the inner surface IS can be more easily distinguished, and by extension, the inner surface IS and the outer surface OS can be more easily distinguished.

However, in the present specification, "different" means that the Munsell color system (100 hues) has a hue of 5 or more (preferably 8 or more, more preferably 10 or more) and a brightness of 1 or more (preferably 2). The above, more preferably 3 or more), or the saturation of 1 or more (preferably 2 or more, more preferably 3 or more), and separated. Further, in the present specification, "similar" or "similar color" means a difference in hue less than 5, lightness less than 1, or saturation less than 1 in the Munsell color system (100 hues). It means that the colors are the same, including the case where they are the same. The color of the ear hook member 20, the color of the inner surface IS of the mask body 10, and the color of the outer surface OS of the mask body 10 are not particularly limited as long as each of the above conditions is satisfied. The white color is a color having a lightness of 7 or more, preferably a color of 8 or more, and more preferably a color of 9 or more.

Alternatively, "different" in color means that the color difference ΔE is 1 or more, preferably ΔE is 2 or more, more preferably ΔE is 3 or more, and further preferably ΔE is 5 or more. There may be. In that case, the color difference ΔE is less than 1 when the colors are “similar” or “similar colors”. The white color has L ^* of 70 or more, preferably 80 or more, and more preferably 90 or more.

(1) Prepare an X-Rite eXact Standard (measurement diameter: 1.5 mm) manufactured by X-Rite.
(2) CIE L ^* a ^* b ^* coordinates of the part to be measured of the sample are measured at 10 or more points by changing the position, and the average value ([L ₁ ^* , a ₁ ^* , b ₁ ^* ]) of them is measured. calculate.
(3) Measure the L ^* a ^* b ^* coordinates of the parts to be compared in the sample at 10 or more points by changing the position, and calculate the average value ([L ₂ ^* , a ₂ ^* , b ₂ ^* ]) of them. do.
(4) The color difference ΔE is calculated by the following equation:

Calculated by

As described above, in the mask 1 according to the present embodiment, when the non-woven fabric of the mask main body 10 is fused with the ear hook member 20 at the fused portion 30, it melts into a film and becomes substantially transparent (film portion 15). ). Therefore, the user applies the color or mixed color of the ear hook member 20 fused to the outer surface OS (second surface) to the inner surface IS (first surface) side via the film portion 15 of the substantially transparent fused portion 30. It has a structure that can be visually recognized from. Here, the color or mixed color of the ear hook member 20 is different from the color of the inner surface IS. Therefore, when the user sees the mask 1 from the inner surface IS side, the film portion 15 of the fused portion 30, which is a color different from the inner surface IS, is placed at the position of the fused portions 30 at both ends in the width direction W. The color or mixed color of the ear hook member 20 that can be grasped through through can be easily confirmed. Therefore, when the user sees the inner surface IS of the mask 1, the color of the inner surface IS and the color grasped through the film portion 15 of the fused portion 30 are different, so that the user's line of sight is on the inner surface IS side. Can be easily directed to the fused portion 30 of. As a result, the user can easily understand that the fused portion 30 on the inner surface IS side is not the fused portion 30 on the outer surface OS side to which the ear hook member 20 is directly fused, and thus the surface is the inner surface IS. Can be made to. Conversely, when the user looks at the outer surface OS of the mask 1, the user can easily grasp that the surface is the outer surface OS because the ear hook member 20 is directly fused. can. That is, the outer surface OS and the inner surface IS can be easily distinguished.
Here, the user previously determines which of the one surface and the other surface of the mask 1 (mask body 10) is the inner surface IS and which is the outer surface OS in the figure or photograph of the package of the mask 1. I know. Alternatively, the user can initially use the mask 1 once, even if he / she does not know which of the one surface and the other surface of the mask 1 is the inner surface IS and which is the outer surface OS, and then after that. Knows which is the inner IS and which is the outer OS. Thereby, the user can easily distinguish one surface and the other surface of the mask 1, and can easily distinguish the outer surface OS and the inner surface IS.
Further, since it is not necessary to provide a symbol on one surface and the other surface of the mask 1 in order to distinguish between the outer surface OS and the inner surface IS, it is possible to suppress the influence on the mask performance of the mask 1 and the increase in cost.
Then, it is suppressed that it takes time to attach the mask 1, the mask 1 can be attached correctly, and the mask 1 can correctly exert its original function.

In the present embodiment, the mask body 10 is located on the left side in the width direction W when viewed from the inner surface IS side, and is located on the left half surface sheet 10a covering the left half of the wearer's face and on the right side in the width direction W. It includes a right half sheet 10a that covers the right half of the wearer's face. The left half-sided sheet 10a and the right-sided half-sided sheet 10a are integrated by joining the opposite ends along the edge. The joints between the ends form a joint 10b. The joint portion 10b is formed, for example, by a method of fusing the ends with heat or ultrasonic waves, a method of joining with an adhesive, or the like. At that time, in the left half-sided sheet 10a and the right half-sided sheet 10a, the end edges of the opposite ends have a substantially curved shape that is convex toward the outside of each sheet. Therefore, both the integrated seats can form a three-dimensional shape (three-dimensional structure) that is concave with respect to the wearer's face when worn by the wearer. In another embodiment, the mask body does not have the left half-face sheet and the right half-face sheet as described above, and has an integrally substantially planar shape (exemplification: Patent Document 2). In yet another embodiment, it has an integral substantially planar shape and has a plurality of folds arranged in the vertical direction (example: Patent Document 1).

In the present embodiment, the mask body 10 is between the inner sheet 12 facing the face side, that is, the inner surface IS side when worn, the outer sheet 11 facing the outer side, that is, the outer surface OS when worn, and the inner sheet 12 and the outer sheet 11. It is provided with a filter sheet 13 located at. The inner sheet 12, the filter sheet 13, and the outer sheet 11 are fused to each other by a plurality of fusion portions 16 (main body fusion portions) arranged so as to border the outer edge of the mask main body 10. The shape of the fused portion 16 is not particularly limited, and examples thereof include a dot shape, a circular shape, an elliptical shape, a polygonal shape, a pattern shape, and a combination thereof. The fused portion 16 is formed by fusing the inner sheet 12, the filter sheet 13, and the outer sheet 11 by heat or ultrasonic waves. At that time, at least a part of each sheet is melted and then cooled and solidified, so that the fused portion 16 is formed into a substantially transparent film. Therefore, the shape of the fused portion 16 can be visually recognized from both the inner surface IS side and the outer surface OS side.

In another embodiment, the mask body 10 includes two or more filter sheets 13. In yet another embodiment, the mask body 10 is made up of one or two sheets as a whole. When the mask body 10 is formed of two sheets, for example, one sheet has the functions of an inner sheet and a filter sheet, the other sheet has the functions of a filter sheet and an outer sheet, one sheet is an inner sheet, and the other is. It has the functions of a filter sheet and an outer sheet, or one sheet has the functions of an inner sheet and a filter sheet, and the other has a function of an outer sheet. When the mask body 10 is formed of one sheet, for example, the sheet has a function of at least one of an inner sheet and an outer sheet and a filter sheet, or the sheet has a function of a filter sheet.

In the present embodiment, the plurality of fusion parts 16 (main body fusion parts) have the shape of a character string in which a plurality of characters readable from the outer surface OS (second surface) are arranged (the fusion part 17 (the main body fusion part). Character string fusion part) is included. The shape of the fused portion 17 can be visually recognized from both the inner surface IS side and the outer surface OS side, similarly to the shape of the fused portion 16. Here, the fused portion 17 is located at the center of the character string in the direction of the character string and is asymmetric with respect to the virtual center line extending in the direction orthogonal to the direction of the character string. In the example showing the outer surface OS of FIG. 2, the character string of the fusion splicer 17 is “Mask”, the center line is located between “a” and “s”, and is orthogonal to the direction of character arrangement. The character string "Mask" is not line-symmetrical, that is, asymmetrical with respect to its center line. Therefore, in the example showing the inner surface IS of FIG. 3, the character string of the fused portion 17 is the one in which "Mask" is reversed. Therefore, by looking at such a character string, the user can easily distinguish between the outer surface OS and the inner surface IS.

In the present embodiment, the inner sheet 12, the filter sheet 13, the outer sheet 11, and the ear hook member 20 are fused to each other at the fused portion 30. The shape of the fused portion 30 is not particularly limited, and examples thereof include a plurality of or a single dot shape, a circular shape, an elliptical shape, a polygonal shape, a grid shape, a dot grid shape, a pattern shape, and a combination thereof. The fused portion 30 is formed by fusing the inner sheet 12, the filter sheet 13, the outer sheet 11 and the ear hook member 20 by heat or ultrasonic waves. At that time, at least a part of the inner sheet 12, the filter sheet 13, and the outer sheet 11 is melted and then cooled and hardened, so that the inner sheet 12, the filter sheet 13, and the outer sheet 11 are in the form of a substantially transparent film. The film portion 15 is formed. When it cools and hardens, a part or all of the end portion 22 of the ear hook member 20 can be melted and fused with the outer sheet 11 (including the film portion 15). As a result, the color or mixed color of the ear hook member 20 can be visually recognized from the inner surface IS side through the film portion 15.

The pair of ear hook members 20 include a left ear hook member 20 in the width direction W and a right ear hook member 20 when viewed from the inner surface IS side. The left ear hook member 20 has one and the other end portions 22 and 22 on the left side at the upper and lower ends of the left half surface sheet 10a in the vertical direction L, respectively. It is joined by a fused portion 30 so as to extend outward from the end portion. Similarly, in the right ear hook member 20, one end 22 and 22 are on the right side of the right end portion of the right half surface sheet 10a, respectively, at the upper and lower ends in the vertical direction L. It is joined by the fused portion 30 so as to extend outward from the end portion of the. In another embodiment, the pair of ear hook members 20 are fused to the inner surfaces IS (first surface) of both side portions of the mask main body 10 in the width direction W by the fused portions 30 and 30.

In the present embodiment, the mask main body 10 has a first extending portion 10P1 in which one end portion in the vertical direction L extends outward in the width direction W at each of both end portions of the mask main body 10 in the width direction W. The other end of the vertical direction L includes a second extending portion 10P2 extending in the outer direction of the width direction W. A constricted portion 10Q confined in the inner direction of the width direction W is located between the first extending portion 10P1 and the second extending portion 10P2. Then, one end of the ear hook member 20 is fused by a fused portion 30 (first extended fused portion) located at the first extended portion 10P1, and the other end is fused with the second extended portion 10P2. It is fused by the fusional part 30 (second extension fusional part) located at. The first extension section 10P1 and the second extension section 10P2 can be collectively referred to as an extension section. Further, the first extension fusion splicing portion and the second extension fusion splicing portion can be collectively referred to as an extension fusion splicing portion. In another embodiment, at least one of the first extending portion 10P1 and the second extending portion 10P2 is not provided, so that the constricted portion 10Q is not provided either. That is, at each of both ends of the mask body 10 in the width direction W, at least one of one end and the other end of the vertical direction L does not extend to the outside of the width direction W and is fused to the non-extending end. The unit 30 is located.

In the present embodiment, the inner sheet 12 and the outer sheet 11 hold the filter sheet 13 from both sides in the thickness direction, and maintain the shape of the mask body 10. From the viewpoint of its function, the inner sheet 12 and the outer sheet 11 preferably have higher ventilation performance and higher rigidity than the filter sheet 13. It is preferable that the inner sheet 12 is more comfortable to the touch. Examples of the basis weight of the inner sheet 12 and the outer sheet 11 include 10 to 100 g / m ² .

In the present embodiment, the filter sheet 13 is a virus, bacteria, dust, pollen, or fine particulate matter (PM2) that tries to pass through the filter sheet together with the gas when a gas such as air flows through the filter sheet 13. It captures and collects substances such as .5) (hereinafter, also simply referred to as "micro substances"). Examples of the basis weight of the filter sheet 13 include 10 to 200 g / m ² .

Examples of the material of the inner sheet 12, the outer sheet 11 and the filter sheet 13 include a non-woven fabric. Examples of the non-woven fabric include spunlaced non-woven fabric, air-through non-woven fabric, spunbonded non-woven fabric, air-laid non-woven fabric, melt blown non-woven fabric, flash spun non-woven fabric, thermal bonded non-woven fabric, carded non-woven fabric, or a non-woven fabric in which some of these are combined. The fiber constituting the non-woven fabric is not particularly limited as long as it is a fiber that can be melted by heat or ultrasonic waves to form a film. Examples of such fibers include synthetic resin fibers (eg, polyethylene, polypropylene, polybutylene, ethylene-vinyl acetate copolymer, ethylene-ethyl acrylate copolymer, ethylene-acrylic acid copolymer, ionomer resin and the like. Polyethylene; polyesters such as polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate, polylactic acid; polyamides such as nylon, etc.) and the like. In addition, some natural fibers (example: wool, cotton) and recycled fibers (example: rayon, acetate) may be contained. The fibers constituting the non-woven fabric may be composed of a single component, or may be composed of composite fibers such as core / sheath type fibers, side-by-side type fibers, and island / sea type fibers. It may be a single-layer non-woven fabric or a laminate in which a single-layer non-woven fabric is laminated (example: SMS non-woven fabric).

As the material of the filter sheet 13, it is preferable that the collection performance of minute substances is higher than that of the inner sheet 12 and the outer sheet 11. In the present embodiment, for example, an electretized non-woven fabric can be used as the material of the filter sheet 13. The electretized non-woven fabric can capture and collect minute substances in gas by the force of static electricity. Such a non-woven fabric can be obtained by applying an electret treatment to the non-woven fabric. The material of the non-woven fabric to be electretized is preferably a non-polar polymer, and examples thereof include polypropylene, polyethylene, polystyrene, or a combination thereof.

Further, the fiber density of the filter sheet 13 is preferably higher than the fiber density of the inner sheet 12 and the outer sheet 11 from the viewpoint of capturing minute substances. Examples of the fiber density of the filter sheet 13 include 0.03 to 0.20 g / cm ³ , preferably 0.05 to 0.10 g / cm ³ . If the fiber density of the filter sheet is too high, the electret treatment may not reach the inside of the filter sheet because the formation of an electric field in the filter sheet by the electret treatment is hindered by the fibers. Further, if the fiber density of the filter sheet is too high, the flow of gas is hindered, it becomes difficult for the gas to pass through the filter sheet 13, and the ventilation performance thereof may be deteriorated. On the other hand, if the fiber density is too low, the number of fibers that capture minute substances may be too small and the collection performance may deteriorate.

The material of the ear hook member 20 is not particularly limited as long as it is hung on the wearer's ear, and examples thereof include elastic members such as round rubber having a circular cross section and flat rubber having a rectangular cross section. Examples of the elastic member include woven rubber or knitted rubber formed by weaving or knitting synthetic resin fibers (which may be elastic fibers). In this embodiment, woven rubber is used. The width of woven rubber does not change even if it is stretched. Therefore, it is preferable to use woven rubber because it is possible to prevent the color of the ear hook member 20 from becoming difficult to see even if the ear hook member 20 is stretched. Further, since the ear hook member 20 does not become thin when it is hung on the ear, it is possible to secure a sufficient area of the portion of the woven rubber that comes into contact with the user's ear, and it is possible to improve the wearing comfort of the mask 1. Therefore, the mask 1 can correctly exhibit its original function and can be worn for a long time.

In this embodiment, the ear hook member 20 is made of woven rubber. In that case, the color of at least one of the warp (example: elastic urethane fiber) and the weft (example: polyester fiber) in the woven rubber is the inner surface IS (first surface) of the mask body 10. Different from the color. In another embodiment, the color of the warp and weft in the woven rubber, which has a larger number of threads per unit volume, is different from the color of the inner surface IS of the mask body. In that case, the color of the other thread may be, for example, a similar color or white. As a result, the color of the ear hook member 20 can be made different from the color of the inner surface IS as a whole.

As a preferred embodiment of the present embodiment, in the present mask 1, the color of the ear hook member 20 is similar to the color of the outer surface OS (second surface) to which the ear hook member 20 is fused. Therefore, when the user sees the inner surface IS (first surface) of the mask 1, the color of the inner surface IS and the color grasped through the fused portion 30 are different, that is, the color of the inner surface IS and the ear. Since the colors or mixed colors of the hanging member 20 are not similar to each other, it is possible to immediately grasp that the surface is not the outer surface OS to which the ear hanging member 20 is directly fused. Conversely, when the user looks at the outer surface OS of the mask 1, the color of the outer surface OS and the color of the fused portion 30 (the color of the ear hook member 20 itself is the color from the outer surface OS side) are similar to each other. Since it is a color, it can be easily grasped that the surface is the outer surface OS. That is, the inner surface IS and the outer surface OS can be immediately distinguished. The similar colors include the same color.

It is combined. Therefore, when the user sees the first surface of the mask 1, that is, the inner surface IS, the color of the inner surface IS and the color grasped through the fused portion 30 are different, and that surface is the inner surface IS. Can be grasped immediately. Conversely, when the user looks at the second surface of the mask 1, that is, the outer surface OS, the ear hook member 20 is directly fused, so that the surface can be immediately grasped as the outer surface OS. That is, the inner surface IS and the outer surface OS can be easily distinguished.

As a preferred embodiment in the present embodiment, in the present mask 1, the color of the ear hook member 20 and the color of the inner surface IS (first surface) of the mask body 10 are 5 or more in the Munsell color system (100 hues). The lightness is 1 or more, or the saturation is 1 or more. Therefore, the user can more easily see the color or the mixed color of the ear hook member 20 from the inner surface IS side via the fused portion 30. That is, it is possible to more easily distinguish between the outer surface OS (second surface) to which the ear hook member 20 is fused and the inner surface IS in which the color or mixed color of the ear hook member 20 can be visually recognized via the fusion unit 30. Thereby, the inner surface IS and the outer surface OS can be easily distinguished.

As a preferred embodiment of the present embodiment, in the present mask 1, since the ear hook member 20 is made of woven rubber, its width hardly changes even when tension is applied in the length direction thereof, and the color of the ear hook member 20 is difficult to see. It can be suppressed. As a result, the user can visually recognize the outer surface OS (second surface) on which the woven rubber as the ear hook member 20 is fused and the color of the woven rubber through the fused portion 30 (inner surface IS). The first surface) and can be easily distinguished. Thereby, the inner surface IS and the outer surface OS can be more easily distinguished by the color. Further, since the width of the woven rubber hardly changes regardless of the tension, it is possible to sufficiently secure the area of the woven rubber that comes into contact with the user's ear. Thereby, the wearing comfort of the present mask 1 can be improved. Therefore, the mask 1 can correctly exhibit its original function and can be worn for a long time.

As a preferred embodiment of the present embodiment, in the present mask 1, in the woven rubber as the ear hook member 20, the color of the warp and weft, whichever has the larger number of threads per unit volume, is the inner surface IS (the first) of the mask body 10. It is different from the color on the first side). Therefore, the user can more easily distinguish between the outer surface OS (second surface) on the side where the woven rubber is fused and the inner surface IS where the color of the woven rubber can be visually recognized through the fused portion 30. Thereby, the inner surface IS and the outer surface OS can be more easily distinguished.

As a preferred embodiment of the present embodiment, in the present mask 1, at the end of the mask body 10 in the width direction W, at least one of both ends of the vertical direction L extends in the outward direction of the width direction W. The ear hook member 20 includes 10P, and at least one end thereof is fused to the fusion splicing portion 30 (extended fusion splicing portion). As described above, by locating the fused portion 30 on the extended portion 10P extending in the outer direction of the width direction W, the user can easily grasp the fused portion 30, so that the fused portion 30 can be used. The color of the ear hook member 20 can be easily visually recognized from the inner surface IS (first surface) side. Therefore, the user can more easily distinguish between the inner surface IS and the outer surface OS.

As a preferred embodiment in the present embodiment, in the present mask 1, in the present mask 1, at the end portion in the width direction W, both ends in the vertical direction L extend in the outward direction in the width direction W. The protrusions 10P1 and 10P2 are included, and the ear hook member 20 has one end and the other end fused to the fusion parts 30 and 30 (first and second extension fusion parts). In this way, by locating the fused portions 30 and 30 on the first and second extended portions 10P1 and 10P2 extending in the outer direction of the width direction W, the fused portions 30 and 30 can be more easily accommodated. Since it can be grasped, the color or mixed color of the ear hook member 20 can be easily visually recognized from the inner surface IS (first surface) side via the fused portions 30 and 30. Therefore, the user can more easily distinguish the inner surface IS and the outer surface OS by the color.

As a preferred embodiment in the present embodiment, in the present mask 1, the fused portion 30 is formed by melting the mask main body 10 and the ear hook member 20 with ultrasonic waves. Therefore, the non-woven fabric of the mask body 10 can be easily formed into a film, whereby the color of the ear hook member 20 located on the outer surface OS (second surface) is transferred to the inner surface IS (first surface IS) via the fused portion 30. It can be easily visible from the surface) side. Thereby, the inner surface IS and the outer surface OS can be more easily distinguished.

As a preferred embodiment in the present embodiment, the mask 1 includes a character string (example: Mask) that can be read from the outer surface OS (second surface), and is asymmetric with respect to the center line in the direction in which the character strings are arranged. A fusion unit 17 (character string fusion unit) is provided. Thereby, the outer surface OS (second surface) and the inner surface IS (first surface) can be easily distinguished from the state of the character string of the fused portion 17. Further, since the fused portion 17 is a fused portion for fusing a plurality of nonwoven fabrics to each other, the fused portion 17 can be formed while suppressing the influence on the mask performance and the increase in cost. Thereby, the inner surface IS and the outer surface can be more easily distinguished by the color.
