Description

The present invention relates to a mask attachment attached to a mask body and a mask provided with the attachment.

As a conventional mask, for example, there is one described in Patent Document 1. The mask described in the document includes a mask body that covers the wearer's nose and mouth, and an ear strap for fixing the mask body to the wearer's face. The mask body is made of a breathable sheet-like material. Ear straps are provided on both the left and right sides of the mask body.

Japanese Unexamined Patent Publication No. 2012-40163

By covering the nose and mouth with the mask body, such a mask has a function of preventing harmful particles (viruses, bacteria, pollen, etc.) from entering the nasal cavity and the oral cavity. However, if a gap is created between both ends of the mask body and the face, there is a problem that harmful particles invade the space inside the mask body (the space between the mask body and the face) through the gap. ..

The present invention has been made in view of the above problems, and an object of the present invention is to provide a mask attachment that makes it difficult for harmful particles to enter the space inside the mask body, and a mask provided with the attachment.

As a result of diligent studies, the present inventor has found that one of the causes of the gap between both ends of the mask body and the face in the conventional mask is the upper end fixing point of the mask body (the part where the upper end of the ear strap is fixed). And it was discovered that it was due to the force from the ear strap acting on the lower end fixing point (the part where the lower end of the ear strap was fixed). That is, at each side end of the mask body, the upper end fixed point and the lower end fixed point receive an inward force from the ear strap (direction from each fixed point toward the other fixed point), so that the side end is loosened, which causes it. It causes the above gap. The present inventor has arrived at the present invention based on such findings.

The mask attachment according to the present invention is a pair of mask attachments attached along both side ends of the mask body that covers the wearer's mouth, and is hung on the wearer's ears on the left and right sides of the mask body. A pair of ear cords are provided, and the attachment for each mask has a position in which one of the intermediate portions of the ear cords is fixed in the attached state in which the attachment for the mask is attached to the mask main body. It is characterized by having a fixed portion of 1.

This mask attachment has a first fixing portion to which one part of the middle portion of the ear strap is fixed. In the attached state, the above-mentioned portion of the ear strap is fixed to the mask attachment. As a result, the force acting directly on the mask body from the ear strap is relaxed, so that both ends of the mask body are less likely to loosen.

Further, the mask according to the present invention is characterized by including the above-mentioned mask attachment and the above-mentioned mask main body.

In this mask, the above-mentioned mask attachment is attached to the mask body. In the attached state, the above-mentioned portion of the ear strap is fixed to the mask attachment. As a result, the force acting directly on the mask body from the ear strap is relaxed, so that both ends of the mask body are less likely to loosen.

According to the present invention, a mask attachment that makes it difficult for harmful particles to enter the space inside the mask body, and a mask provided with the attachment are realized.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same elements are designated by the same reference numerals, and duplicate description will be omitted.

FIG. 1 is a rear view showing an embodiment of a mask attachment and a mask according to the present invention. Further, FIG. 2 is a front view showing the embodiment. The mask 1 includes a mask body 10 and a pair of mask attachments 20. The mask body 10 has a sheet shape and covers the wearer's mouth. The mask body 10 may cover only the nose and mouth of the eyes, nose and mouth, or may cover only the mouth. 1 and 2 show the inner surface (the surface facing the wearer's face) and the outer surface of the mask body 10, respectively. The mask body 10 is made of a breathable material. As such a material, for example, non-woven fabric, paper, or gauze can be used.

A pair of ear straps 12 are provided on both the left and right sides of the mask body 10. When the mask 1 is worn, the ear strap 12 is hung on the wearer's ear. As a result, the mask body 10 is fixed to the wearer's face. The upper end 12a and the lower end 12b of the ear strap 12 are fixed to the mask body 10. The upper end fixing point of the mask body 10 (the portion where the upper end portion 12a of the ear strap 12 is fixed) is located in the vicinity of the upper end 10a of the mask body 10. Further, the lower end fixing point of the mask main body 10 (the portion where the lower end portion 12b of the ear strap 12 is fixed) is located in the vicinity of the lower end 10b of the mask main body 10. The ear strap 12 has elasticity. As the ear cord 12, for example, a rubber cord can be used. As the mask body 10 and the ear strap 12, a general commercially available mask (either a disposable type or a repeatedly used type) may be used.

FIG. 3 is a rear view showing the mask main body 10. A mark 14 indicating the mounting position of the mask attachment 20 is attached to the inner surface of the mask main body 10. In the present embodiment, the mark 14 is composed of two sets of key marks. One set consists of two key marks provided near the left end 10c of the mask main body 10, and indicates the position of the corner of one of the mask attachments 20. The other set consists of two key marks provided near the right end 10d of the mask body 10, and indicates the position of the corner of the other mask attachment 20.

Returning to FIGS. 1 and 2, the pair of mask attachments 20 are attached along both side ends (left end 10c and right end 10d) of the mask body 10. The mask attachment 20 may be attached to the mask body 10 in advance, or may be attached by the wearer at the time of use. The mask attachment 20 is attached to the mask body 10 so as to overlap only a part of the mask body 10 when viewed from the front. At this time, from the viewpoint of ensuring the ease of breathing through the mask body 10, it is preferable that most of the mask body 10 (a portion of 3/4 or more of the total area of the mask body 10) does not overlap with the mask attachment 20. ..

One mask attachment 20 is attached along the left end 10c of the mask body 10. The other mask attachment 20 is attached along the right end 10d of the mask body 10. These mask attachments 20 are provided separately from each other, and have a symmetrical structure including the positions and sizes of the cut portion 22, the cut portion 24, and the fixing means 26, which will be described later. There is.

The mask attachment 20 is attached to the mask body 10 so as to protrude from both side ends of the mask body 10. Specifically, one of the mask attachments 20 is attached to the mask body 10 so as to protrude from the left end 10c of the mask body 10. Similarly, the other mask attachment 20 is attached to the mask body 10 so as to protrude from the right end 10d of the mask body 10. In this way, each mask attachment 20 is attached to the mask body 10 so that only a part thereof overlaps the mask body 10 when viewed from the front.

Further, the mask attachment 20 is attached along the entire both side ends of the mask body 10. Specifically, one mask attachment 20 is attached along the entire left end 10c of the mask body 10. Similarly, the other mask attachment 20 is attached along the entire right end 10d of the mask body 10.

FIG. 4 is a front view showing the mask attachment 20. The figure shows the outer surface of the mask attachment 20 which is attached along the left end 10c of the mask main body 10 on behalf of the pair of mask attachments 20. Here, the outer surface of the mask attachment 20 is a state in which the mask attachment 20 is attached to the mask body 10 (hereinafter referred to as "attached state"), and is opposite to the inner surface which is a surface facing the wearer's face. Refers to the side surface. In the present embodiment, each mask attachment 20 has a rectangular sheet shape. The length of each mask attachment 20 in the left-right direction (equal to the left-right direction of the mask body 10) is, for example, 1 cm or more and 4 cm or less. The length of each mask attachment 20 in the vertical direction (equal to the vertical direction of the mask body 10) is substantially equal to the lengths of the left end 10c and the right end 10d of the mask body 10, for example, 7 cm or more and 11 cm or less.

Each mask attachment 20 has a notch 22 (first notch), a notch 24 (second notch), and a fixing means 26. The cut portion 22 is a fixing portion (first fixing portion) in which one place 12c of the intermediate portion of each ear cord 12 is fixed in the attached state. In the mounted state, the cut portion 22 is fixed by hooking the intermediate portion 12c of each ear cord 12. The cut portion 24 is a fixing portion (second fixing portion) to which the other portion 12d of the intermediate portion of each ear cord 12 is fixed in the mounted state. In the mounted state, the cut portion 24 is fixed by hooking the portion 12d at the intermediate portion of each ear cord 12. The middle portion of the ear strap 12 is a portion of the ear strap 12 excluding the upper end portion 12a and the lower end portion 12b.

The cut portion 22 is composed of a straight cut line. The length of the cut portion 22 is, for example, 5 mm or more and 15 mm or less. In the present embodiment, the cut portion 22 extends diagonally with respect to the vertical direction of the mask main body 10. Specifically, the cut portion 22 gradually moves away from the upper end of each mask attachment 20 as it approaches the outer end of each mask attachment 20. Here, the outer end of the mask attachment 20 is the end of both sides of each mask attachment 20 that is farther from the center line of the mask body 10 (a straight line that bisects the mask body 10 to the left and right) in the mounted state. Refers to the side edge.

The starting end 22a of the notch 22 is located on the outer end of each mask attachment 20. The end 22b of the cut portion 22 is located at the central portion of each mask attachment 20 (a portion other than the end portion of each mask attachment 20). That is, the cut portion 22 extends from the outer end to the central portion of each mask attachment 20. Further, the entire notch portion 22 exists in the protruding portion (the portion protruding from the mask main body 10 in the attached state) of each mask attachment 20. In order to hook the ear cord 12 to the notch portion 22, the ear cord 12 may be inserted from the start end 22a through the notch portion 22 to the end end 22b. At this time, it is preferable that there is no looseness in the portion from the upper end portion 12a to the portion 12c of the ear cord 12.

The end 22b of the notch 22 is located between the upper end 12a and the lower end 12b of the ear strap 12 in the vertical direction of the mask body 10 in the mounted state (see FIGS. 1 and 2). That is, when viewed from the front, the distance from the end 22b to the straight line including the upper end 10a of the mask body 10 is larger than the distance from the upper end 12a to the straight line, and from the end 22b to the straight line including the lower end 10b of the mask body 10. The distance is larger than the distance from the lower end 12b to the straight line.

The end 22b of the notch 22 is located closer to the upper end 12a than the lower end 12b of the ear strap 12 in the attached state. That is, the distance from the terminal 22b to the upper end 12a is smaller than the distance from the terminal 22b to the lower end 12b. In the mounted state, the vertical distance d1 (see FIG. 5) from the terminal 22b to the upper end 12a is preferably 5 mm or more and 20 mm or less. The distance d1 is defined as a distance between a straight line L1 extending in the left-right direction of the mask body 10 through the upper end portion 12a and a straight line L2 extending in the left-right direction of the mask body 10 passing through the end point 22b.

The cut portion 24 is composed of a straight cut line. The length of the cut portion 24 is, for example, 5 mm or more and 15 mm or less. In the present embodiment, the cut portion 24 extends diagonally with respect to the vertical direction of the mask main body 10. Specifically, the cut portion 24 gradually moves away from the lower end of each mask attachment 20 as it approaches the outer end of each mask attachment 20.

The starting end 24a of the cut portion 24 is located on the outer end of each mask attachment 20. The end 24b of the notch 24 is located at the center of each mask attachment 20. That is, the cut portion 24 extends from the outer end to the central portion of each mask attachment 20. Further, the entire notch portion 24 exists in the eclipse portion of each mask attachment 20. In order to hook the ear cord 12 to the notch portion 24, the ear cord 12 may be inserted from the start end 24a through the notch portion 24 to the end end 24b. At this time, it is preferable that there is no looseness in the portion from the lower end portion 12b of the ear cord 12 to the portion 12d.

The end 24b of the notch 24 is located between the end 22b of the notch 22 and the lower end 12b in the vertical direction of the mask body 10 in the mounted state (see FIGS. 1 and 2). That is, when viewed from the front, the distance from the end 24b to the straight line including the upper end 10a of the mask body 10 is larger than the distance from the end 22b to the straight line, and the distance from the end 24b to the straight line including the lower end 10b of the mask body 10. Is greater than the distance from the lower end 12b to the straight line.

The end 24b of the notch 24 is located closer to the lower end 12b than the upper end 12a of the ear strap 12 in the attached state. That is, the distance from the terminal 24b to the lower end 12b is smaller than the distance from the terminal 24b to the upper end 12a. In the mounted state, the vertical distance d2 (see FIG. 5) from the terminal 24b to the lower end 12b is preferably 5 mm or more and 20 mm or less. The distance d2 is defined as the distance between the straight line L3 that passes through the lower end portion 12b and extends in the left-right direction of the mask main body 10 and the straight line L4 that passes through the terminal portion 24b and extends in the left-right direction of the mask main body 10.

The fixing means 26 is arranged near the inner end (side end opposite to the outer end) of each mask attachment 20, and extends along the inner end. The fixing means 26 is a means for fixing each mask attachment 20 to the mask main body 10. In the present embodiment, the fixing means 26 is made of an adhesive. One of the mask attachments 20 is fixed to the vicinity of the left end 10c of the mask body 10 by being attached to the inner surface of the mask body 10 via the fixing means 26. The other mask attachment 20 is fixed to the vicinity of the right end 10d of the mask body 10 by being attached to the inner surface of the mask body 10 via the fixing means 26.

The mask attachment 20 is removable from the mask body 10. Here, "detachable" means that the mask attachment 20 can be alternately switched between the state of being attached to the mask body 10 and the state of not being attached to the mask body 10 without damaging the mask body 10 and the mask attachment 20. Say that. The removable mask attachment 20 can be realized by appropriately adjusting the adhesive force of the adhesive (fixing means 26).

The mask attachment 20 has flexibility. The material of the mask attachment 20 may be the same as or different from the material of the mask body 10. As the material of the mask attachment 20, for example, in addition to non-woven fabric, paper, and gauze, urethane, soft rubber, silicon, and the like can be used. In the present embodiment, the thickness of the mask attachment 20 is larger than the thickness of the mask body 10. The mask attachment 20 may have the same color as the mask body 10 or may have a different color. A pattern may be drawn on the mask attachment 20. Examples of such a symbol include a symbol such as an animal, a sweet (dessert), a vehicle, or a character such as an animation or a cartoon.

The effect of this embodiment will be described. The mask attachment 20 has a fixing portion (cut portion 22) to which one portion 12c of the intermediate portion of the ear strap 12 is fixed. In the attached state, the portion 12c of the ear strap 12 is fixed to the mask attachment 20. As a result, the force acting directly on the mask body 10 from the ear strap 12 is relaxed, so that both ends of the mask body 10 are less likely to loosen. Therefore, a mask attachment 20 that makes it difficult for harmful particles to enter the space inside the mask body 10 and a mask 1 provided with the attachment 20 are realized.

Further, the mask attachment 20 has a fixing portion (cut portion 24) to which the other portion 12d of the intermediate portion of the ear strap 12 is fixed. In the attached state, the portion 12d of the ear strap 12 is also fixed to the mask attachment 20. As a result, the force acting directly on the mask body 10 from the ear strap 12 is further relaxed, so that both ends of the mask body 10 are less likely to loosen.

As described above, in the present embodiment, the point of action of the force from the ear strap 12 is shifted from the upper end fixing point and the lower end fixing point of the mask body 10 to the cut portion 22 and the cut portion 24 of the mask attachment 20, respectively. As a result, the force from the ear strap 12 is released from the mask body 10 to the mask attachment 20. As a result, it is possible to prevent the force that causes the slack at both ends of the mask body 10 from acting directly on the mask body 10.

Further, since the mask attachment 20 closes at least a part of the gap between both side ends of the mask body 10 and the face, it becomes easy to keep the humidity of the space inside the mask body 10 high. By increasing the humidity of the space, the effect of reducing the infectivity of influenza virus and the like can be expected.

In the present embodiment, as a first fixing portion in which the portion 12c of the intermediate portion of the ear strap 12 is fixed, a notch portion 22 in which the portion 12c is hooked is provided. As a result, the first fixed portion can be realized with a simple configuration. Similarly, as a second fixing portion to which the portion 12d of the intermediate portion of the ear cord 12 is fixed, a notch portion 24 in which the portion 12d is hooked is provided. As a result, the second fixed portion can be realized with a simple configuration.

The end 22b of the notch 22 is located between the upper end 12a and the lower end 12b of the ear strap 12 in the vertical direction of the mask body 10 in the mounted state. In this case, the cut portion 22 has an ear as compared with the case where the terminal 22b is located near the upper end of each mask attachment 20 (the region on the straight line L1 shown in FIG. 5 and the region above the straight line L1). It becomes difficult to receive an inward force from the string 12.

The end 24b of the cut portion 24 is located between the end 22b of the cut portion 22 and the lower end portion 12b in the vertical direction of the mask main body 10 in the mounted state. In this case, the cut portion 24 is in the ear as compared with the case where the terminal 24b is located near the lower end of each mask attachment 20 (the region on the straight line L3 shown in FIG. 5 and the region below the straight line L3). It becomes difficult to receive an inward force from the string 12.

With reference to FIGS. 6 to 8, the mechanism by which the mask attachment 20 is less likely to receive an inward force from the ear strap 12 will be described. FIG. 6 shows a case where the end 22b and the end 24b are located near the upper end and the lower end of each mask attachment 20, respectively. In this case, when the mask 1 is worn, the terminal 22b receives a diagonally downward force F1 from the ear strap 12, and the terminal 24b receives a diagonally upward force F2 from the ear strap 12. Therefore, the component force f1 of the force F1 and the component force f2 of the force F2 become inward forces and act on the terminal 22b and the terminal 24b, respectively. The component force f1 and the component force f2 are the component forces in the vertical direction when the force F1 and the force F2 are decomposed into the vertical direction and the horizontal direction of the mask main body 10, respectively. As shown in FIG. 7, such an inward force causes the mask attachment 20 to loosen. FIG. 6 is a view of the mask attachment 20 of FIG. 6 as viewed from the right.

On the other hand, in FIG. 8, in the vertical direction of the mask body 10, the end 22b is located between the upper end 12a and the lower end 12b of the ear strap 12, and the end 24b is between the end 22b and the lower end 12b. It shows the case of being located. In this case, the directions of the force F1 and the force F2 approach horizontal (the left-right direction of the mask body 10). Then, the values of the component force f1 and the component force f2 (the inward direction is positive) become smaller. This means that the mask attachment 20 is less likely to receive an inward force from the ear strap 12. As a result, the mask attachment 20 is less likely to loosen, so that the degree of adhesion of the mask attachment 20 to the face can be increased when the mask 1 is attached.

The end 22b of the notch 22 is located closer to the upper end 12a than the lower end 12b of the ear strap 12 in the attached state. Such a configuration is suitable for shifting the point of action of the force from the ear strap 12 from the upper end fixing point of the mask body 10 to the cut portion 22 of the mask attachment 20. Further, the end 24b of the cut portion 24 is located closer to the lower end portion 12b than the upper end portion 12a of the ear strap 12 in the attached state. Such a configuration is suitable for shifting the point of action of the force from the ear strap 12 from the lower end fixing point of the mask body 10 to the cut portion 24 of the mask attachment 20.

The larger the vertical distance d1 from the end 22b of the notch 22 to the upper end 12a of the ear strap 12, is advantageous for reducing the above-mentioned component force f1. From this point of view, the distance d1 is preferably 5 mm or more. On the other hand, if the distance d1 is too large, the upper portion of each mask attachment 20 (the portion above the straight line L2 shown in FIG. 5) tends to be rolled up when the mask 1 is attached. From this point of view, the distance d1 is preferably 20 mm or less.

The larger the vertical distance d2 from the end 24b of the notch 24 to the lower end 12b of the ear strap 12, is advantageous for reducing the above-mentioned component force f2. From this point of view, the distance d2 is preferably 5 mm or more. On the other hand, if the distance d2 is too large, the lower part of each mask attachment 20 (the part below the straight line L4 shown in FIG. 5) tends to be rolled up when the mask 1 is attached. From this point of view, the distance d2 is preferably 20 mm or less.

The cut portion 22 extends diagonally with respect to the vertical direction of the mask main body 10. In this case, the state in which the ear cord 12 is hooked on the cut portion 22 is stably maintained as compared with the case where the extending direction of the cut portion 22 is perpendicular to the vertical direction of the mask body 10. It will be easier.

The cut portion 24 extends diagonally with respect to the vertical direction of the mask main body 10. In this case, the state in which the ear cord 12 is hooked on the cut portion 24 is stably maintained as compared with the case where the extending direction of the cut portion 24 is perpendicular to the vertical direction of the mask body 10. It will be easier.

The cut portion 22 extends diagonally as it approaches the outer end of each mask attachment 20 so as to gradually move away from the upper end of the mask attachment 20. Similarly, the notch portion 24 extends diagonally as it approaches the outer end of each mask attachment 20 so as to gradually move away from the lower end of the mask attachment 20. In this case, as shown in FIG. 9, an outward force (component force f3, f4) is likely to act on the cut portion 22 and the cut portion 24 of each mask attachment 20. The component force f3 is a component force in the vertical direction when the force F1 is decomposed in a direction parallel to the cut portion 22 and a direction perpendicular to the cut portion 22. Further, the component force f4 is a component force in the vertical direction when the force F2 is decomposed into a direction parallel to the cut portion 24 and a direction perpendicular to the direction. As a result, the mask attachment 20 is pulled up and down, so that the mask attachment 20 can be made more difficult to loosen.

The starting end 22a of the notch 22 is located on the outer end of the mask attachment 20. Such a configuration is advantageous for facilitating the passage of the ear strap 12 through the notch 22. Similarly, the starting end 24a of the cut portion 24 is located on the outer end of the mask attachment 20. Such a configuration is advantageous for facilitating the passage of the ear strap 12 through the notch 24.

The mask attachment 20 is attached to the mask body 10 so as to protrude from both side ends of the mask body 10. Therefore, the eclipse portion of each mask attachment 20 can block harmful particles that try to enter the space inside the mask body 10. By blocking the harmful particles on the outside of the mask body 10 in this way, it is possible to prevent the harmful particles from invading the space inside the mask body 10.

The mask attachment 20 is attached along the entire side end of the mask body 10. In this case, the effect of blocking harmful particles by the mask attachment 20 can be enhanced as compared with the case where the mask attachment 20 is attached along only a part of both side ends of the mask body 10.

The thickness of the mask attachment 20 is larger than the thickness of the mask body 10. This makes it difficult for harmful particles to pass through the mask attachment 20. This also contributes to the improvement of the blocking effect of harmful particles by the mask attachment 20. Further, increasing the thickness of the mask attachment 20 is also advantageous in maintaining a stable state in which the ear strap 12 is hooked on the cut portions 22 and 24.

When the mask attachment 20 has a color different from that of the mask body 10, the fashionability of the mask 1 can be improved. The same applies when a pattern is drawn on the mask attachment 20. In particular, animal, sweets, vehicles, or character designs are of great interest to children. Therefore, when these patterns are drawn on the mask attachment 20, it becomes easy for the child to wear the mask 1 without dislike.

The mask attachment 20 has fixing means 26. Therefore, the mask attachment 20 can be fixed to the mask main body 10 without separately preparing a fixing means. In particular, when the fixing means 26 is an adhesive, the mask attachment 20 can be easily fixed to the mask body 10.

The mask attachment 20 is removable from the mask body 10. As a result, the mask 1 can be used in either the state where the mask attachment 20 is attached to the mask body 10 or the state where the mask attachment 20 is removed, which enhances convenience for the wearer.

The mask body 10 is marked with a mark 14 indicating the mounting position of the mask attachment 20. Thereby, when the mask attachment 20 is attached, the alignment of each mask attachment 20 with respect to the mask main body 10 can be easily performed.

The ear strap 12 has elasticity. In this case, the tension (contraction force) of the ear strap 12 increases the force acting on the point of action of the force from the ear strap 12. Therefore, the problem of slackening at both ends of the mask body 10 due to the force from the ear strap 12 becomes remarkable. Therefore, as described above, the present embodiment capable of relaxing the force acting directly on the mask body 10 from the ear strap 12 becomes particularly useful.

The present invention is not limited to the above embodiment, and various modifications are possible. In the above embodiment, the mask main body 10 may have a bag-shaped or pocket-shaped water-retaining material accommodating portion for accommodating the water-retaining material. In that case, the humidity of the space inside the mask main body 10 can be increased by using the mask 1 with the water-retaining material accommodated in the water-retaining material accommodating portion.

In the above embodiment, the mask attachment 20 may be in a charged state. The mask attachment 20 can be realized by using a non-woven fabric or the like charged with static electricity by corona treatment, plasma treatment, or the like as the material of the mask attachment 20. In this case, the static electricity of the mask attachment 20 can adsorb and capture harmful particles. As a result, the effect of blocking harmful particles by the mask attachment 20 can be further improved.

In the above embodiment, the mask attachment 20 may contain an antibacterial component. In that case, since it is possible to suppress the propagation of various germs, the mask attachment 20 and thus the mask 1 can be used more hygienically.

In the above embodiment, the case where each mask attachment 20 is composed of one unfolded sheet is exemplified. However, each mask attachment 20 may be formed by bending one sheet, for example, as shown in FIG. FIG. 11 is a schematic view showing a state of the mask attachment 20 of FIG. 10 as viewed from below. Further, FIG. 12 is a developed view showing the mask attachment 20 of FIG. In addition, in FIG. 11, in order to make it easy to see, a gap is provided between the bent sheets.

Each mask attachment 20 has a mountain fold line M1, a valley fold line V1 to V3, and cuts C1 and C2. The mask attachment 20 shown in FIG. 10 can be obtained by making a mountain fold along the mountain fold line M1 and making a valley fold along the valley fold lines V1 to V3. The cut C1 and the cut C2 constitute the cut portion 22 and the cut portion 24, respectively. The cuts C1 and C2 may be formed before each mask attachment 20 is bent along the mountain fold line M1 and the valley fold lines V1 to V3, or may be formed after the fold. By bending one sheet in this way to form the attachments 20 for each mask, it is possible to secure a large thickness of the attachments 20 for each mask even if a thin sheet is used.

In the above embodiment, the case where the thickness of the mask attachment 20 is larger than the thickness of the mask main body 10 is illustrated. However, the thickness of the mask attachment 20 may be equal to the thickness of the mask main body 10 or smaller than the thickness of the mask main body 10.

In the above embodiment, the case where the mask attachment 20 is attached to the mask body 10 so as to protrude from both side ends of the mask body 10 is illustrated. However, the mask attachment 20 may be attached to the mask body 10 so as not to protrude from both side ends of the mask body 10. That is, the mask attachment 20 may be attached to the mask body 10 so that the entire mask attachment 20 overlaps the mask body 10 when viewed from the front.

In the above embodiment, the case where the mask attachment 20 is attached along the entire both side ends of the mask body 10 is illustrated. However, the mask attachment 20 may be attached only along a part of both side ends of the mask body 10. That is, one mask attachment 20 may be attached only along a part of the left end 10c of the mask body 10, and the other mask attachment 20 may be attached only along a part of the right end 10d of the mask body 10. It may be attached.

In the above embodiment, the case where the start end 22a of the cut portion 22 and the start end 24a of the cut portion 24 are located on the outer end of each mask attachment 20 has been exemplified. However, the starting ends 22a and 24a may be located on an end portion (inner end, upper end, or lower end) other than the outer end of each mask attachment 20.

In the above embodiment, the case where the end 22b of the notch 22 is located between the upper end 12a and the lower end 12b of the ear strap 12 in the vertical direction of the mask body 10 is exemplified. However, the end 22b may be located near the upper end of each mask attachment 20.

In the above embodiment, the case where the end 24b of the cut portion 24 is located between the end 22b of the cut portion 22 and the lower end portion 12b in the vertical direction of the mask main body 10 is exemplified. However, the terminal 24b may be located near the lower end of each mask attachment 20.

In the above embodiment, the case where the cut portions 22 and 24 extend diagonally with respect to the vertical direction of the mask main body 10 is illustrated. However, the extending direction of each of the cut portions 22 and 24 may be parallel to the vertical direction of the mask main body 10 or may be perpendicular to the vertical direction.

In the above embodiment, the case where the cut portions 22 and 24 are in a straight line is illustrated. However, each of the cut portions 22 and 24 may be composed of two or more line segments (folded lines), for example, as shown in FIG. In the figure, the cut portion 22 is composed of a line segment extending in the left-right direction of the mask main body 10 from the start end 22a, and a line segment continuous with the line segment and extending in the vertical direction of the mask main body 10 to the end end 22b. Similarly, the cut portion 24 includes a line segment extending in the left-right direction of the mask main body 10 from the start end 24a, and a line segment continuous with the line segment and extending in the vertical direction of the mask main body 10 to the end end 24b. Alternatively, the cut portions 22 and 24 may have a curved shape, for example, as shown in FIG.

In the above embodiment, the case where both the cut portion 22 and the cut portion 24 are provided in the mask attachment 20 is illustrated. However, the mask attachment 20 may be provided with only one of the cut portion 22 and the cut portion 24. When only the notch portion 24 is provided, the notch portion 24 corresponds to the "first notch portion".

In the above embodiment, the case where the mask attachment 20 is fixed to the inner surface of the mask body 10 is illustrated. However, the mask attachment 20 may be fixed to the outer surface of the mask body 10. In that case, the mark 14 is attached to the outer surface of the mask body 10. Further, the fixing means 26 is provided on the inner surface of the mask attachment 20.

In the above embodiment, the case where the fixing means 26 is provided on the mask attachment 20 is illustrated. However, it is not essential to provide the fixing means 26 on the mask attachment 20. When the mask attachment 20 is not provided with the fixing means 26, the mask attachment 20 may be fixed to the mask main body 10 by a fixing means such as an adhesive tape separately prepared by the wearer.

In the above embodiment, the case where the ear strap 12 has elasticity is illustrated. However, the ear strap 12 does not have to have elasticity. In that case, for example, a non-woven fabric can be used as the material of the ear strap 12.

In the above embodiment, the case where the first and second fixed portions are the first and second cut portions, respectively, is illustrated. However, as the first and second fixing portions, means other than the incision may be used as long as the portions 12c and the portions 12d in the middle portion of the ear strap 12 can be fixed, respectively. For example, the first and second fixing portions may be the sandwiching portion 32 and the sandwiching portion 34 shown in FIG. 15, respectively. As shown in FIG. 16, the sandwiching portion 32 includes a plate-shaped portion 32a and a connecting portion 32b. FIG. 15 is a view of the holding portion 32 of FIG. 15 as viewed from the vertical direction of the mask main body 10. One end of the connecting portion 32b is connected only to a part (a portion including the center) of the plate-shaped portion 32a. The other end of the connecting portion 32b is fixed to the mask attachment 20. The sandwiching portion 32 sandwiches and fixes the intermediate portion 12c of the ear strap 12 between the plate-shaped portion 32a and the mask attachment 20.

As shown in FIG. 17, the sandwiching portion 34 includes a plate-shaped portion 34a and a connecting portion 34b. FIG. 15 is a view of the holding portion 34 of FIG. 15 as viewed from the vertical direction of the mask main body 10. One end of the connecting portion 34b is connected only to a part (a portion including the center) of the plate-shaped portion 34a. The other end of the connecting portion 34b is fixed to the mask attachment 20. The sandwiching portion 34 sandwiches and fixes the intermediate portion 12d of the ear strap 12 between the plate-shaped portion 34a and the mask attachment 20. As the material of the sandwiching portions 32 and 34, for example, metal, resin, paper or the like can be used.

Alternatively, when the mask attachment 20 is pre-attached to the mask body 10, the first and second fixing portions have the portions 12c and the portions 12d of the ear straps 12 by means of welding, adhesion, stapler, etc., respectively. May be fixed in advance. Examples of welding include ultrasonic welding, heat welding and the like. Hot melt adhesion is preferable for adhesion. For the stapler, it is preferable to use a resin or paper stapler.
