Description

The present invention relates to a mask.

Conventionally, masks such as woven cloths and non-woven fabrics that cover the mouth and nose have been widely used as countermeasures against infections such as viruses and bacteria in daily life, but nowadays, under various circumstances such as when playing sports. However, it is required to wear a mask to prevent infection.

By the way, a cloth mask that is normally used can prevent infection of the user and infection of people around the user by covering the mouth and nose of the user with almost no gap. However, in an environment where a lot of water may adhere to the face, such as sweating from playing sports or bathing in water such as a pool, a cloth mask can get wet. At the same time as the air permeation becomes insufficient, the mask may stick to the user's face as a whole, making it difficult for the user to continuously wear the mask. Therefore, it is conceivable to form the mask using a sheet such as resin, and to form it in a cup shape so that a gap is formed between the user's face and the mask when the mask is worn by the user. When such a mask is used in an environment where a large amount of water adheres to the face, unlike a cloth mask, the shape is maintained even if it gets wet, and it is possible to prevent the mask from sticking to the face as a whole. However, the peripheral part of the mask may still stick to the user's face, which narrows the gap between the mask and the user's face, which may cause discomfort and difficulty in breathing.

Therefore, an object of the present invention is to provide a mask capable of suppressing discomfort during use and facilitating breathing even when the mask is used in an environment where it gets wet.

It is a front view which shows the half part (the half part on the other side in the width direction) of the mask main body part of the mask of FIG.

Hereinafter, embodiments of the present invention (hereinafter referred to as “the present embodiment”) will be described in detail, but the present invention is not limited to the present embodiment.
As shown in FIG. 1, the mask of the present embodiment is attached to the sheet-shaped mask main body 2 having the vertical direction and the width direction and both sides of the mask main body 2 in the width direction, and is to be worn by the user. It is a mask 1 provided with a mounting member 3 (not shown in FIG. 1).
Since the mask body 2 of the mask 1 of the present embodiment is in the form of a sheet, even if a large amount of water adheres to the mask 1, the user wears the mask 1 on his face so as to cover his mouth and nose (hereinafter referred to as “)”. The shape of the mask 1 can be maintained, and even if the mask gets wet, it can be prevented from sticking to the user's face as a whole like a cloth mask.
Therefore, the mask 1 of the present embodiment is not particularly limited, but can be suitably used, for example, for water resistance, that is, in an environment where a large amount of water may adhere to the face. It can be used in an environment where sweating a lot, or in an environment such as a pool where people are exposed to water (in a pool facility, etc.). In particular, when used in a pool, it can be used, for example, when walking underwater, or when instructing or monitoring a swimmer by the pool. Then, by using the mask 1 of the present embodiment, it is possible to suitably prevent the infection of the user and the infection of the people around the user in such an environment.

Here, in the present embodiment, the mask main body 2 is a main part for preventing infection of the user and infection to people around the user, and the mask is worn on the face of the user. It has a portion located below the middle in the vertical direction, specifically, from the vicinity of one ear to the vicinity of the other ear.
The mask main body 2 has a vertical direction (vertical direction in FIG. 1) and a width direction (horizontal direction in FIG. 1). The vertical direction of the mask main body 2 is a direction corresponding to the vertical direction of the user's face when the mask is attached, and the upward direction of the mask main body 2 is the upward direction of the user and the lower side of the mask main body 2. The direction is the user's downward direction. Further, the width direction of the mask main body 2 is a direction corresponding to the left-right direction of the user's face when the mask is attached, and the outside of the width direction of the mask main body 2 is the mask main body when the mask is attached. The direction in which the user's ear is located with respect to the center line L1 of 2, and the inside in the width direction of the mask main body 2 is the direction opposite to the outside in the width direction of the mask main body 2 in the mask wearing state. This is the direction toward the center line L1. Further, one of the width directions of the mask main body 2 is to the right of the user, and the other of the width direction of the mask main body 2 is to the left of the user.
Further, the mask main body 2 has outer and inner surfaces, and the outer surface refers to the surface of a pair of surfaces facing the peripheral side of the user when the mask is attached, and the inner surface. Refers to the surface of a pair of surfaces facing the user's face when the mask is attached.

In the example of FIG. 1, the mask main body portion 2 is located at the center portion 21 of the mask mainly corresponding to the mouth, nose, and cheek, and is located on both sides of the central portion 21 of the mask in the width direction to attach the mounting member 3. It has a pair of mounting portions 22.
As shown in FIG. 3, the mask central portion 21 of the illustrated example extends from the vicinity of one cheek of the user's face to the vicinity of the other cheek in the width direction in the mask wearing state, and extends in the vertical direction. , It extends from the middle of the nose to the tip of the chin. More specifically, the contour of the upper end of the mask central portion 21 is the center line L1 (described later) as shown in the figure showing the half portion (the other half portion in the width direction) of the mask main body portion 2 in FIG. It has a shape that gently tilts downward toward the outside in the width direction. As a result, when the mask is worn, the upper end of the central portion 21 of the mask faces outward in the width direction and passes through the apex of the cheekbone from the vicinity of the middle of the user's nose in the vertical direction while avoiding the lower eyelids of the eyes. ..
On the other hand, the contour of the lower end of the mask central portion 21 gently tilts upward from the center line L1 toward the outside in the width direction, and then substantially upward, as shown in the figure showing the half portion of the mask main body portion 2 in FIG. It has a shape that follows. As a result, the lower end of the central portion 21 of the mask is shaped so as to follow the shape of the user's lower jaw when the mask is attached.

Further, in the mask 1 of the present embodiment, as shown in FIG. 1, a virtual line located at the center in the width direction of the mask main body 2 and extending in the vertical direction is set as the center line L1 and is masked with respect to the center line L1. The portion of the main body 2 on one side in the width direction and the portion on the other side in the width direction are designated as one side portion 23 and the other side portion 24, respectively.
In this case, the state in which the mask main body 2 is bent along the center line L1 is viewed from below of the mask main body 2, and at least below the mask main body 2, a space is provided between the one side portion 23 and the other side portion 24. Form. In other words, when the mask main body 2 is bent along the center line L1, one side portion 23 and the other side portion 24 of the mask main body 2 sandwich the center line L1 at least below the mask main body 2. It is designed to repel each other and open. Therefore, even in the mask-mounted state as shown in FIG. 3, the one-side portion 23 and the other-side portion 24 of the mask main body portion 2 spread each other with the center line L1 at least in the portion below them. Can be shaped. As a result, at least the lower part of the mask 1 is separated from the face of the user (particularly near the mouth and chin of the user), and a space can be secured between the mask 1 and the face of the user. ..

Therefore, according to the mask 1 of the present embodiment, since the mask main body 2 is in the form of a sheet, its three-dimensional shape even if it gets wet with moisture, specifically, one side portion 23 and the other side of the mask main body 2. It is possible to maintain a shape in which the side portions 24 and the side portions 24, at least in the portions below them, spread out from each other across the center line L1. The mask 1 of the present embodiment has such a shape and is shaped so as to be separated from the face of the user (particularly near the user's mouth and chin tip), so that the mask 1 is in a wet state. However, it is necessary to sufficiently reduce the fact that the peripheral part of the mask 1 sticks to the user's face and secure a gap between the mask 1 and the user's face (especially near the user's mouth and chin). Can be done. Therefore, according to the mask 1 of the present embodiment, even when the mask 1 is used in an environment where it gets wet, it is possible to suppress discomfort during use and facilitate breathing.

In the present specification, the above-mentioned "state in which the mask main body 2 is bent at the center line L1" means that one side portion 23 and the other side portion 24 are bent around the center line L1 in the mask main body portion 2. After that, each of the pair of positions (positions on the virtual line extending in the vertical direction) separated from the center line L1 by 50 mm on both sides in the width direction is the center line L1, one side portion 23 up to the relevant position, and the center line L1. Open so that the angle formed by the other side portion 24 to the position on the other side is about 60 °, and then the portion outside the width direction from the pair of positions around the center line L1. It means a state in which the mask main body 2 is bent so as to be overlapped with each other (when the mask body 2 is bent, the mask main body portion 23 is not crushed so as to be in contact with the whole of the other side portion 24).
Further, in the present specification, the center line L1 is a virtual line located at the center in the width direction of the mask main body 2 and extending in the vertical direction, but more specifically, it is the center in the width direction of the mask main body 2. It is a virtual line that is located in the center of the thickness direction and extends in the vertical direction. Further, the center line L1 may be a curved line instead of a straight line, for example, when the shape of the mask main body 2 is three-dimensional.

Then, in the present embodiment, when the state in which the mask main body 2 is bent along the center line L1 is viewed from below the mask main body 2, at least one of the mask main bodies 2 is at the lower end of the mask main body 2. The distance at the position where the distance between the side portion 23 and the other side portion 24 is maximum is preferably 5 mm or more, more preferably 10 mm or more, still more preferably 15 mm or more. When the distance is 5 mm or more, at least the lower part of the mask 1 is separated from the face of the user (especially near the user's mouth and chin) when the mask is worn, and the mask 1 and the user More space can be secured between them.
On the other hand, the upper limit of the distance is not particularly limited from the viewpoint of securing a space between the mask 1 and the user, but the distance is preferably 30 mm or less from the viewpoint of facilitating the wearing of the mask 1. ..

Further, in the present embodiment, the state in which the mask main body 2 is bent along the center line L1 is viewed from below of the mask main body 2, and at least below the mask main body 2, one side portion 23 and the other side portion 24 The method of forming the space is not particularly limited, but a method of forming at least a portion of the mask main body 2 within a range of 50 mm on both sides in the width direction from the center line L1 with one sheet, or a mask. A method of providing, for example, a support member having a repulsive force against the inward bending of the mask main body 2 so as to extend in the width direction across the center line L1 can be mentioned below the main body 2. Either one or both of them can be used.
Specifically, in the former method, since a portion in a predetermined range is formed by one sheet around the center line L1, one side portion 23 and the other side can be used by utilizing the repulsive force against the bending of the sheet. A space can be formed with the portion 24 (in the illustrated example, the mask main body portion 2 is formed of one sheet). Further, in the latter method, for example, two sheets corresponding to one side portion 23 and the other side portion 24 of the mask main body portion 2 are overlapped with each other, and the two sheets are joined to each other at their edges in that state. In this case, at least a portion of the mask main body portion 2 within a range of 50 mm on both sides in the width direction from the center line L1 is formed by two sheets. In this case, if the mask main body 2 is bent along the center line L1, the one-sided portion 23 and the other-sided portion 24 are in contact with each other and overlapped with each other, and the space between the one-sided portion 23 and the other-side portion 24 is formed. Is not formed. However, when a member having a repulsive force against bending is provided below the mask main body 2 so as to extend in the width direction across the center line L1, at least due to the repulsive force of the support member, at least. Below the mask body 2, a space can be formed between the one-sided portion 23 and the other-sided portion 24.

Here, the mask main body 2 of the mask 1 of the present embodiment is in the form of a sheet as described above, but specifically, the mask main body 2 is formed of a flexible sheet. As the material of the mask main body 2, a resin such as soft polyvinyl chloride or polyurethane resin, rubber such as natural rubber, or various synthetic rubbers (for example, silicon rubber) can be used. Further, the mask main body 2 may be formed from a material produced by foaming these materials, and for example, a cloth used for a wet suit or the like, which is a material obtained by foaming chloroprene rubber or the like, can also be used. .. The thickness of the mask main body 2 varies depending on the material used, but is preferably, for example, 0.5 to 2.0 mm, more preferably 0.8 to 1.5 mm, and even more preferably 0. It is 8 to 1.2 mm.
Further, when the mask main body 2 is made of a transparent material, it becomes easier for people around the user to grasp the facial expression and mouth movement of the user, and the colored material or the colored material can be used. When formed of a material that is a combination of transparent materials, the designability can be improved.

Further, the material of the mask main body 2 is a material that recovers to 90 ° or more around the crease 3 seconds after releasing the pressing for bending when the test piece is evaluated for bending under the following conditions. It is preferable, more preferably 135 ° or more, still more preferably 150 ° or more.
In the above bending evaluation, a test piece having a length of 50 mm and a width of 50 mm is prepared, the test piece is immersed in water for 10 seconds, and then the test piece after immersion is bent in the middle in the horizontal direction (position of 25 mm). The state is maintained and placed on a horizontal plane, and then the pressure for bending is released, and the state after 3 seconds (angle centered on the crease) is observed from a direction parallel to the direction of the crease.

Further, as shown in FIG. 1, the mask main body portion 2 of the present embodiment includes a part of the upper end portion of the one side portion 23 and the other side portion 24 located symmetrically with respect to the part and the center line L1. It can have a joint portion 25 that is joined to each other with a portion of the upper end portion. In the example shown in FIG. 1, the mask main body 2 possesses two joint portions 25 above the mask main body 2 and in the vicinity of the center line L1.
By having such a joint portion 25, when the mask is worn, the joint portion 25 and its surroundings cover the user's nose as a nose pad, and the mask 1 is supported, so that the mask can be easily worn.

In particular, when the above-mentioned joint portion 25 is provided and a portion of the mask main body portion 2 within a range of at least 50 mm on both sides in the width direction from the center line L1 is formed by one sheet, the mask is attached. The gap between the upper end of the mask body 2 and the user's face can be reduced, and the user's exhaled breath blows into the user's eyes through the gap between the mask 1 and the face (near the cheeks). It can be suppressed.
Specifically, as shown in FIG. 1, since the joint portion 25 joins one side portion 23 and the other side portion 24 of the mask main body portion 2, the joint portion 25 is viewed with the mask attached. On the other hand, one side portion 23 and the other side portion 24 (the upper end portion of the one side portion 23 and the other side portion 24) adjacent to the outside in the width direction are along the height direction of the user's nose (the front-back direction of the user). Easy to extend in the direction. On the other hand, one side portion 23 and the other side portion 24 below the joint portion 25 (the portion below the upper end portion of the one side portion 23 and the other side portion 24) sandwich the center line L1 as described above. Since it is made of one sheet, it is easy to extend in the direction along the width direction of the face when viewed with the mask attached. That is, the upper end portion of the one side portion 23 and the other side portion 24 tends to follow the shape of the nose, while the portion below the upper end portion of the one side portion 23 and the other side portion 24 is near the cheek of the user ( Especially near the cheekbone), it becomes easier to follow the shape. Therefore, when the above-mentioned joint portion 25 is provided and the portion of the mask main body portion 2 within a range of at least 50 mm on both sides in the width direction from the center line L1 is formed by one sheet, the mask is attached. It is possible to prevent the exhaled breath of the user from being blown into the eyes of the user through the gap between the mask 1 and the face (near the cheek).
If the one-side portion 23 and the other-side portion 24 below the joint portion 25 are not formed by one sheet with the center line L1 interposed therebetween, the one-side portion 23 below the joint portion 25 is formed. And the other side portion 24 also tends to extend in the direction along the height direction of the user's nose (the front-back direction of the user). As a result, when the mask is worn, the mask body tends to stick to the user's nose more and cause discomfort. Further, at the upper end of the mask main body 2, a gap is likely to be formed on the user's face (particularly from the nose to the cheekbone area) when the mask is attached.

Further, as shown in FIG. 2, the outer end 25e in the width direction of the joint portion 25 (the position on the outermost side in the width direction of the joint portion 25) is located on one side portion 23 and the other side portion 24 from the upper end of the center line L1. It is preferably located at 10 to 40 mm on one side and the other side in the width direction of. In other words, at the upper end portion of the mask main body portion 2, one side portion 23 and the other side portion 24 that have been joined to each other are separated from the widthwise outer end 25e of the joint portion 25 toward the widthwise outer side. The outer end 25e in the width direction of the joint portion 25 is the branch position 25e of the mask main body 2. Then, in the present embodiment, it is preferable that the branch position 25e is located 10 to 40 mm outward in the width direction from the upper end of the center line L1.
As described above, the position of the outer end 25e in the width direction of the joint portion 25 is located at a position moved 10 mm or more from the upper end of the center line L1 to the outer side in the width direction of the one side portion 23 and the other side portion 24, whereby the joint portion is formed. The length of 25 tends to be appropriate in relation to the height of the user's nose, which makes it easier to wear the mask 1. Further, the position of the outer end 25e in the width direction of the joint portion 25 is located at a position moved 40 mm or less from the upper end of the center line L1 to the outer side in the width direction of the one side portion 23 and the other side portion 24, so that the mask is attached. Therefore, the gap between the upper end of the mask main body 2 and the face of the user can be effectively reduced.
From the same viewpoint, the widthwise outer end 25e of the joint portion 25 is moved from the upper end of the center line L1 to a position moved by 10 to 30 mm from the upper end of the center line L1 to the widthwise one side and the other side of the one side portion 23 and the other side portion 24. It is more preferable to be present in.

The joint portion 25 is measured in the vertical direction downward from the upper ends of the one-side portion 23 and the other-side portion 24, but the length is preferably in the range of 20 mm or less, more preferably 15 mm, and further preferably. Is 12 mm. By allowing the joint portion 25 to exist in such a range, it is possible to prevent the joint portion 25 from becoming too large.

Further, the angle α formed by the center line L1 and the virtual line connecting the upper end of the center line L1 and the outer end 25e in the width direction of the joint portion 25 in the front view of the half portion of the mask main body portion 2 is 45 to 120 °. It is preferable to have.
When the angle α is 45 ° or more, the upper end of the mask main body 2 can be easily aligned with the user's cheek while wearing the mask, and when the angle α is 120 ° or less. It is possible to reduce the discomfort caused by the one side portion 23 and the other side portion 24 below the joint portion 25 being too close to the user's nose while wearing the mask.
From the same viewpoint, the angle α is more preferably 45 to 90 °, still more preferably 50 to 70 °.

Further, in the present specification, the above-mentioned "front view of a half of the mask main body 2" means that the mask main body 2 is cut along the center line L1 and viewed, but the center line L1 is used. It can be substantially synonymous with observing a state in which the mask main body 2 is folded so that the one-side portion 23 and the other-side portion 24 are overlapped with each other at the center. Further, the "outside in the width direction of the mask main body 2" in the half part of the mask main body 2 is the outside in the width direction in the mask wearing state, and the "outside in the width direction" in the half part of the mask main body 2 is the "outside of the mask main body 2". The "center side in the width direction" means the opposite direction to the "outside in the width direction of the mask main body 2" in the half portion of the mask main body 2.

Adhesives, fasteners such as hook-and-loop fasteners, line fasteners and point fasteners, rivet joints and the like may be used for joining, and if the sheet is made of a thermoplastic resin, they may be fused. From the viewpoint of preventing peeling due to the use of the mask 1, rivet joining and dot buttons are preferable. Further, from the viewpoint of making it possible to adjust the position of the outer end 25e in the width direction of the joint portion 25, a fastener such as a dot button is preferable.
It is also possible to join from the upper end of the center line L1 to the outer end 25e in the width direction of the joining portion 25. Further, as in the example of FIG. 1, a plurality of joining portions 25 may be present, or different joining methods may be combined.

By the way, when viewed with the mask attached, the position of the mask corresponding to the user's mouth is usually located in front of the user rather than the position of the upper end of the mask that touches or approaches the user's nose. However, as shown in FIG. 3 with the mask attached, the mask 1 of the present embodiment has the same positional relationship. Specifically, the position of the upper end portion of the mask 1 that comes into contact with or approaches the user's nose is a branch between the one-side portion 23 and the other-side portion 24 that are connected to each other above the mask main body portion 2. This is the branch position 25e, and in the case of this example, it corresponds to the outer end 25e in the width direction of the joint portion 25, as shown in FIGS. Further, the position of the mask 1 corresponding to the mouth of the user is a point 26 on the center line L1 at a distance of 70 mm downward from the branch position 25e in the front view of the half portion of the mask main body 2 (hereinafter referred to as a point 26). It is referred to as the mask front side position 26). Also in the mask 1 of the present embodiment, the mask front side position 26 is located in front of the user from the branch position 25e when viewed in the mask wearing state, in other words, the half portion of the mask main body portion 2. In front view, the mask front side position 26 is located closer to the center side in the width direction of the mask main body 2 than the branch position 25e.
The position of the mask 1 corresponding to the user's mouth (the position on the front side of the mask 26) is on the center line L1 at a distance of 70 mm downward from the branch position 25e in the front view of the half of the mask main body 2. The reason for this is that the position of the mask 1 corresponding to the user's mouth is usually located at a distance of about 70 mm downward from the branch position 25e in the mask-worn state.

Then, in the mask 1 of the present embodiment, when the virtual tangent line L2 to which the center line L1 touches is drawn at the position 26 on the front side of the mask in the front view of the half portion of the mask main body portion 2, the virtual tangent line L2 passes through the lower end of the center line L1. The line L3 parallel to the tangent line L2 preferably passes through the branch position 25e and is located closer to the center in the width direction than the line L4 parallel to the virtual tangent line L2. By doing so, when the mask is worn, the space between the lower portion of the mask 1 and the user (particularly the chin) becomes large, and the user can easily breathe.
In the illustrated example, since the center line L1 is a substantially straight line in the front view of the half portion of the mask main body 2, the virtual tangent line L2 in contact with the center line L1 drawn at the position 26 on the front side of the mask is the center line L1. The line L3 that substantially coincides and passes through the lower end of the center line L1 and is parallel to the virtual tangent line L2 is located on the center side in the width direction with respect to the line L4 that passes through the branch position 25e and is parallel to the virtual tangent line L2 and is located on the center line L1. Is consistent with. Further, the width direction of the mask main body portion 2 may be a direction orthogonal to the virtual tangent line L2 to which the center line L1 touches at the position 26 on the front side of the mask.

Further, from the viewpoint of increasing the space between the lower portion of the mask 1 and the user (particularly the tip of the jaw) when the mask is attached, the lower end of the center line L1 is viewed from the front of the half of the mask main body 2. The line L3 parallel to the virtual tangent line L2 passes through the middle of the branch position 25e and the virtual tangent line L2 (the position where the distance between the branch position 25e and the virtual tangent line L2 is halved) and is parallel to the virtual tangent line L2. It is preferably located on the center side in the width direction with respect to the straight line.

Here, in the present embodiment, the mounting portion 22 of the mask main body 2 is located on both outer sides of the mask main body 2 in the width direction and above, as shown in FIG. Further, the attachment portion 22 of the mask main body portion 2 extends from the vicinity of the cheek (particularly the cheekbone) of the user's face to the vicinity of the ear in the width direction when viewed with the mask attached. Further, the mounting portion 22 of the mask main body 2 is seen in front of a half of the mask main body 2, and as shown in FIG. 2, in the vertical direction, half of the maximum vertical length of the mask main body 2 is more specific. It can be a portion having a length of 1/3. The length of the mask main body 2 in the vertical direction can be a length measured along a direction parallel to the virtual tangent line L2 in which the center line L1 touches at the position 26 on the front side of the mask.

In the illustrated example, as shown in FIG. 3, a string is used as the mounting member 3 to be attached to the mounting portion 22, but in this case, the mounting portion 22 is used as the mounting member 3 as shown in FIG. It is possible to have one or more holes 27 for attaching the string to the string (in the example shown in the figure, there are a total of 6 holes in 2 steps in the vertical direction and 3 rows in the width direction). Further, when the user has a plurality of holes 27, the user can appropriately select the holes 27 through which the string is passed so that the holes 27 can be arbitrarily adjusted according to the size of the head.

Further, as shown in FIG. 3, the mounting portion 22 can have a repulsion generating means 221 capable of repelling the mounting portion 22 to the outside of the user's surface while the mask is mounted. Specifically, the mounting portion 22 of the mask 1 is located in the portion from the vicinity of the cheek to the vicinity of the ear (near the temple) of the user in the mask wearing state, and the mounting portion 22 is placed near the temple by the repulsion generating means 221. It can be positioned so that it rises above the face from the face.
In the present embodiment, the presence of the repulsion generating means 221 improves the sticking of the portion existing around the cheekbone of the user in the mask main body 2 to the face in the mask wearing state, and the wearability of the mask 1 is improved. Can be improved. That is, when the mask is worn, the mask body 2 extends outward in the width direction on the surface of the user's nose, cheekbones, and cheekbones, and the position where the cheekbones of the human face are located is relatively bulging. Since the position where the cheeks are located is relatively dented with respect to the cheekbones, when the mask 1 is attached, the mask body 2 (particularly the central part 21 of the mask) is lifted or has a low contact state on the face where the cheekbones are located, and the mask is masked. In some cases, the wearability of 1 was lowered. On the other hand, when the mounting portion 22 has the repulsion generating means 221, the mask main body portion 2 is warped in the portion between the mask central portion 21 and the mounting portion 22 of the mask main body portion 2, and the mask main body portion 2 Due to the restoring force against the warp, a force for pressing the face is generated in the portion of the mask main body 2 corresponding to the cheekbone position. Therefore, the repulsion generating means 221 increases the sticking to the face near the temples, and can improve the wearability of the mask 1.

Further, in the present embodiment, the specific repulsion generating means 221 can be a mounting portion 22 having a length measured along the width direction of 60 mm or more. By setting the length of the mounting portion 22 to that length, the user of the mask 1 can mount the mask 1 by bending a part of the outside of the mounting portion 22 in the width direction inward as shown in FIG. The portion 22 repels the outside of the user's surface. From the viewpoint of generating the repulsive force more reliably, it is preferably 80 mm or more. On the other hand, if the length of the mounting portion 22 is too long, the handleability of the mask 1 may deteriorate. Therefore, the length is preferably 120 mm or less, more preferably 100 mm or less.
The length of the mounting portion 22 is a length measured along the width direction of the mask main body portion 2, but specifically, it may be a length measured along the extending direction of the mounting portion 22. can.

In the present embodiment, the mounting member 3 is provided on the mounting portion 22 of the mask main body portion 2, and a string (band) can be used or a hook for hanging on the upper part of the user's ear can be used. When the mounting member 3 is used as a string, as shown in the illustrated example, a pair of mounting portions 22 are connected with a string so that the mask 1 as a whole is looped so that it can be mounted on the user's head. It is also possible to form a loop with a string on each pair so that it can be hung around the ear. In the present embodiment, from the viewpoint of making it possible to mount the mask 1 more reliably, it is preferable to use a string as the mounting member 3 and connect the pair of mounting portions 22 with the string to form a loop as the entire mask 1.
When the mounting member 3 is a string, the string is not particularly limited, but is preferably elastic, and may be formed of a relatively flexible rubber having rubber elasticity or a plastic material such as silicon or polyurethane. can.
Further, when the mounting member 3 is a hook for hanging on the upper part of the user's ear, the material is not particularly limited as long as it is a material having a hardness sufficient to maintain the shape. For example, it can be formed by using metal, resin, or rubber. In addition, in order to use it in an environment with a lot of moisture and to avoid sharpening the tip if it breaks, the material has elasticity and hardness enough to maintain its shape, for example, silicon, rubber, etc. Polyurethane is preferred.

Here, in the first modification of the present embodiment, the mask main body portion 2 can have a strip-shaped elastic sheet 28 at the upper end portion as shown in FIG. Since the mask main body 2 has the elastic sheet 28, it is possible to reduce the gap between the mask main body 2 and the user's face at the upper end of the mask when the mask is attached, whereby the user's breath can be reduced. Can be prevented from being caught in the eyes of the user through the gap between the sheet and the cheeks of the face and causing discomfort.
The specific elastic sheet 28 is not particularly limited as long as it has elasticity, but it can be formed of a relatively flexible rubber having rubber elasticity or a plastic material such as silicon or polyurethane, and more preferably. It is porous. A specific material is porous polyurethane.

The elastic sheet 28 preferably has a length (width) measured in a direction orthogonal to the extending direction of the elastic sheet 28, preferably 3 to 20 mm, more preferably 6 to 15 mm, and further preferably 6 to 6. It is 10 mm. When the length is 3 mm or more, the exhaled breath is effectively suppressed from passing through the gap between the sheet and the cheeks of the face, and when the length is 20 mm or less, the area in contact with the user's face is increased. Since it is suppressed from becoming large, it is possible to make the user less likely to feel uncomfortable.
Further, it is preferable that the elastic sheet 28 extends to a range where a gap between the sheet and the cheeks of the face is generated when the mask is attached, but more preferably, the user is at least wearing the mask from the branch position 25e. It is to extend to the position corresponding to the cheekbone. Specifically, it preferably extends from the branch position 25e to at least 30 mm outward in the width direction of the mask main body 2, more preferably at least 50 mm outward in the width direction of the mask main body 2, and even more preferably. It extends at least to the outside in the width direction of the mask central portion 21 in the mask main body portion 2. By extending the elastic sheet 28 as described above, it is possible to effectively suppress the exhalation from passing through the gap between the sheet and the cheeks of the face.
Further, the elastic sheet 28 preferably has a thickness of 3 to 10 mm, more preferably 4 to 8 mm. When the thickness is 3 mm or more, the gap between the sheet and the cheeks of the face can be easily reduced, and when the thickness is 10 mm or less, the user can be less likely to feel uncomfortable.
Further, the elastic sheet 28 can be attached to the mask main body 2 by using an adhesive or by heat fusion.

Here, in the second modification of the present embodiment, as shown in FIG. 5, the mask main body 2 is the upper end 30 of the mask main body 2, and the upper part of the sheet 6 of the mask main body 2 is the mask. It is possible to have a bent portion 5 bent on the inner surface side of the.
More specifically, as shown in the left side view in FIG. 6, the bent portion 5 is a portion corresponding to the upper portion of the sheet 6 for manufacturing the mask main body portion 2 (the upper part in the figure is the upper part of the mask). .. For example, in the sheet 6 for manufacturing the mask main body 2 shown in FIG. 1, the upper portion of the sheet 6 does not project upward, but in the sheet 6 shown in FIG. 6, the upper portion thereof is, for example, the mask main body 2 on the center line L1. The upper part of the sheet 6 is projected above the upper end of the mask, as shown in the left side view to the right side view in FIG. 6, on the inner surface side of the mask (in other words, among a pair of surfaces of the mask). The bent portion 5 is formed by being bent toward the user's face side while wearing the mask.
Of the sheet 6 for manufacturing the mask main body 2, the portion other than the portion to be the bent portion 5 (the upper part of the sheet 6) is also referred to as the main portion of the sheet 6.

In the present embodiment, since the mask main body 2 has the bent portion 5, it is possible to reduce the gap between the mask main body 2 and the user's face at the upper end of the mask in the mask wearing state, thereby reducing the gap between the mask main body 2 and the user's face. It is possible to prevent the exhaled breath of the user from being caught in the eyes of the user through the gap between the sheet 6 and the cheeks of the face and causing discomfort.

The length LG1 of the bent portion 5 from the upper end of the mask main body 2 (the upper end of the bent portion 5) to the lower end of the bent portion 5 is not particularly limited, but as shown in FIG. 7, the half portion of the mask main body 2 In front view, the length LG1 can be 20 to 40 mm, preferably 25 to 35 mm, and more preferably 30 mm. The length LG1 is a length measured along the vertical direction from the upper end of the mask main body 2 to the lower end of the bent portion 5 in the front view of the half of the mask main body 2.
By setting the length LG1 of the bent portion 5 to the above range, it is possible to effectively prevent the exhaled breath of the user from passing through the gap between the sheet 6 and the cheeks of the face.

Further, the range of existence of the bent portion 5 in the upper end portion 30 of the mask main body portion 2 is not particularly limited, but as shown in FIG. 5, the bent portion 5 is present in the mask central portion 21 from the mounting portion 22 for mounting the mounting member. Can be done. By allowing the bent portion 5 to exist in this way, it is possible to effectively prevent the exhaled breath of the user from passing through the gap between the sheet 6 and the cheeks of the face.
More specifically, with respect to the inner end in the width direction (the end on the center side in the width direction) of the bent portion 5, the length LG2 measured along the width direction from the center line L1 to the inner end in the width direction of the bent portion 5 is In the front view of the half portion of the mask main body 2 shown in FIG. 7, it is preferably 10 mm or more, more preferably 30 mm or more outward from the center line L1 of the mask main body 2 in the width direction. Further, when the mask main body 2 has the joint portion 25 as shown in FIG. 5, the inner end in the width direction of the bent portion 5 is the width direction of the joint portion 25 in the front view of the half portion of the mask main body 2. It is also preferable that it is located outside in the width direction with respect to the outer end.
Further, the outer end in the width direction of the bent portion 5 is preferably located at the mounting portion 22 of the mask body, but more preferably, as shown in FIG. 5, the outer end in the width direction of the mask main body 2 (mounting portion). It is located at the outer end in the width direction of 22).

As shown in FIGS. 5 and 6, the bent portion 5 is preferably chamfered in the width direction, and specifically, the bent portion 5 is directed from the inside to the outside of the mask main body 2 in the width direction. The length from the upper end to the lower end of the bent portion 5 can be gradually increased until it reaches the above-mentioned predetermined length. With such a shape, the contact pressure of the mask main body 2 on the user's face can be dispersed, and the adhesion to the skin can be softened.
Further, as shown in FIG. 5, the bent portion 5 is formed on the mask main body portion 2 in the same shape as a pair, but may have different shapes.
Further, when the bent portion 5 is formed in the mounting portion 22, a hole 27 through which the mounting member (not shown) penetrates is formed in each of the bent portion 5 and the main portion of the sheet 6, as shown in FIG. However, it is also possible to allow the mounting member to pass through each hole 27.

The means for maintaining the bent state of the bent portion 5 is not particularly limited, and for example, the bent portion 5 is bent by joining the entire bent portion 5 to the main portion. The state may be maintained (not shown).
However, in the present embodiment, as a means for maintaining the bent state of the bent portion 5, as shown in FIG. 5, a part of the lower end portion of the bent portion 5 (before forming the bent portion 5). Focusing on the sheet 6 in the above state, it is preferable that a part of the upper end portion 30 of the upper part of the sheet 6) is joined to a part of the main part of the sheet 6. By joining in this way, in the bent portion 5, a space can be formed between the bent portion 5 and the main portion due to the restoring force against the bending of the sheet 6.
Since the face of the user (from the cheekbones to the temples) has irregularities, the mask may be lifted or have a low contact state according to the mask wearing state, and the wearability of the mask 1 may be deteriorated. On the other hand, in this way, in the bent portion 5, a space is formed between the bent portion 5 and the main portion so as to match the unevenness of the user's face (over the cheekbones and temples) when the mask is attached. The mask can be easily contacted, the adhesion to the skin can be softened, and the wearability of the mask can be improved. Further, since a part of the lower end portion of the bent portion 5 is joined to a part of the main portion of the sheet 6, the restoring force (repulsion) of the bent portion 5 is appropriately suppressed, and the skin adheres to the skin. Can be softened.
As a means for maintaining the bent state of the bent portion 5, in the state where the bent portion 5 is formed, a hole 27 through which the mounting member penetrates is provided in the mounting portion 22 (the main portion of the bent portion 5 and the sheet 6). It is also possible to maintain the bent state of the bent portion 5 by the mounting member formed in each) and passed through the hole 27, which also forms a space between the bent portion 5 and the main portion in the bent portion 5. be able to.

The joining 51 may use an adhesive, a fastener such as a hook-and-loop fastener, a line fastener, a point fastener, a rivet joint, or the like, or may be fused if the sheet 6 is made of a thermoplastic resin. As shown in FIG. 5, from the viewpoint of forming a space between the bent portion 5 and the main portion, a fastener or a rivet joint, more preferably a point fastener or a rivet joint can be used.

When a part of the lower end portion of the bent portion 5 is joined to a part of the main portion of the sheet 6, the length LG3 from the upper end of the mask body to the upper end of the joint 51 is as shown in FIG. In the front view of the half of the mask main body 2, it is preferably 20 to 26 mm, more preferably 25 mm. By setting the length to LG3 in this way, the contactability of the mask according to the unevenness of the user's face (cheekbone and temples) in the mask-wearing state is improved, the adhesion to the skin is softened, and the mask is made. It is possible to further improve the wearability of the wearer. The length is a length measured along the vertical direction from the upper end of the mask main body 2 to the upper end of the joint 51 downward.

Further, when a part of the lower end portion of the bent portion 5 is joined to a part of the main portion of the sheet 6, from the inner end in the width direction (the end on the center side in the width direction) to the outer end of the bent portion 5. Can also be joined together. Preferably, the inner end in the width direction of the joint 51 is positioned outside the inner end in the width direction of the bent portion 5. By doing so, the restoring force (repulsion) of the bent portion 5 can be adjusted more appropriately, and the wearability can be effectively improved.
Further, more preferably, as shown in FIG. 7, the length LG4 measured along the width direction from the center line L1 of the mask body to the inner end in the width direction of the joint 51 is the half portion of the mask body 2. In front view, it is set to 110 to 130 mm. By setting the length LG4 within a predetermined range, the restoring force (repulsion) inside the bent portion 5 in the width direction (center side in the width direction) is appropriately relative to the restoring force outside the width direction of the bent portion 5. It can be made larger to match the unevenness of the user's face (especially the large dents between the nose and cheeks and the dents around the temples), improving the contact of the mask and softening the adhesion to the skin. , The wearability can be effectively improved.
As described above, it is preferable that the inner end in the width direction of the joint 51 is located outside the inner end in the width direction of the bent portion 5, but the position of the outer end in the width direction of the joint 51 (the width direction of the joint 51). Length) can be arbitrary. In other words, all the bent portions 5 outside the width direction of the inner end of the joint 51 in the width direction may be joined, or may be joined halfway. Although not particularly limited, in FIG. 5, the joint 51 is a rivet joint at one place.

By the way, in the present embodiment, the mask main body 2 has a through hole 29 at a position corresponding to the user's mouth when the mask is attached, and the mask 1 can open and close the through hole 29. A sheet-shaped cover member 4 joined on the outer surface of the portion 2 can be provided. Specifically, the through hole 29 is at the center of the mask main body 2 in the width direction (for example, within a range of 50 mm on both sides in the width direction with the center line L1 interposed therebetween), and is at the center in the vertical direction (for example, from the upper end to the lower direction). Can be in the area (within a range of 120 mm). The width direction range of the region where the through hole 29 exists is preferably within a range of 35 mm on both sides in the width direction with the center line L1 interposed therebetween, and more preferably within a range of 20 mm on both sides in the width direction. Further, the vertical range of the region where the through hole 29 exists is preferably within a range of 100 mm downward from the upper end, and more preferably a position 30 mm downward from the upper end and a position 100 mm downward from the upper end. It is in the area sandwiched between.
In the illustrated example, one through hole 29 exists so as to pass through the center line L1, but a plurality of through holes 29 may exist as long as they are in a position corresponding to the user's mouth when the mask is attached. ..
Then, in the present embodiment, when the through hole 29 exists, as shown in FIG. 1 and the like, the sheet-shaped cover member 4 is provided in the range where the through hole 29 exists. Further, the cover member 4 is joined on the outer surface of the mask main body 2 so that the through hole 29 can be opened and closed. In the illustrated example, the upper end portion of the cover member 4 and both end portions in the width direction are riveted to the mask main body portion 2 at two places, whereby the cover member 4 is upwardly started from the upper end portion thereof. It can be turned up (that is, the through hole 29 can be opened and closed). In addition to the illustrated example (upper end portion of the cover member 4), the joint portion of the cover member 4 may be one end portion, the other end portion, or the lower end portion in the width direction of the cover member 4. Further, as a joining method, in addition to rivet joining, an adhesive may be used or fusion may be performed.

As described above, when the mask main body 2 has the through hole 29 and the mask 1 includes the cover member 4, the cover member 4 is in a mask-worn state and talks with a person at a relatively distant position. By turning up and opening the through hole 29, it is possible to make it easier to talk to the person at the distant position. Specifically, when the mask is attached, the cover member 4 is provided in a place where the voice is easily muffled and is difficult to be clearly transmitted to a person at a distant position (especially in a place where the voice is easily resonated such as a pool facility). By turning over, you can make it easier to convey your voice clearly. When talking to a person at a distant position, it is estimated that the risk of spreading infection by vocalization is low even if the through hole 29 is opened.
Further, when the cover member 4 is joined to the mask main body 2 at the upper end or the lower end of the cover member 4 (when the starting point of opening / closing of the cover member 4 is the upper end or the lower end), the mask is attached to the mask. Since 1 is curved along the width direction, when the cover member 4 is turned up by hand and then released, a restoring force is generated against the deformation (turning up) of the cover member 4. Therefore, in such a case, since the cover member 4 tries to return to the closed state naturally, the operation when closing the cover member 4 can be simplified.
Further, when the cover member 4 is joined to the mask main body 2 at one end or the other end in the width direction of the cover member 4 (the opening / closing starting point of the cover member 4 is one end or the other end in the width direction). In the case), by providing a fastener at the end opposite to the starting point of opening and closing, it is possible to easily maintain the closed state of the cover member 4.

The cover member 4 can be formed of the same material as the material that can be used in the mask main body 2, and specifically, the cover member 4 can be formed of a flexible sheet. As specific materials, synthetic resins such as soft polyvinyl chloride and polyurethane resins, rubber materials such as natural rubber, and various synthetic rubbers can be used. The material of the cover member 4 may be the same as or different from the material of the mask main body 2. The thickness of the cover member 4 is preferably 0.5 to 2.0 mm, more preferably 0.7 to 1.5 mm, and even more preferably 0.8 to 1.2 mm.

Although the embodiments of the present invention have been described above with reference to the drawings, the mask of the present invention is not limited to the above example, and the mask of the present invention can be appropriately modified.

According to the present invention, it is possible to provide a mask capable of suppressing discomfort during use and facilitating breathing even when the mask is used in an environment where it gets wet.
