Description

The present invention relates to a three-dimensional cloth mask, specifically a three-dimensional cloth mask having a mask body made of woven cloth.

In 2020, the pandamic of the new global coronavirus infection "COVID-19" will occur, and a mask as an infection prevention device, especially under the chin, can be covered, and it is inexpensive and has a virus catching property. There is a shortage of expensive pleated non-woven masks.
Therefore, although it is inferior to the pleated non-woven fabric mask in terms of price and function, "three-dimensional cloth mask" such as Patent Document 1 has recently attracted attention.
The conventional three-dimensional cloth mask includes a mask body made of a bendable woven cloth in which the central part covering the mouth and nose bulges like a cup, and a pair of ear hooks arranged on the left and right sides of the mask body. It is a thing.

Masks that can be washed and used, [Searched on September 12, 2nd year of Reiwa], Internet <URL https: // item. Rakuten. co. jp / hmj-shop / 10000008 />

However, in the three-dimensional cloth mask of Patent Document 1, the central portion of the mask body bulging like a cup covering the mouth and nose is composed of a soft woven cloth. Therefore, when the mask was worn, the woven cloth was sucked by breathing and clung to the mouth, causing suffocation and discomfort. Moreover, the woven cloth of the cup part was deformed every time the person breathed, and the appearance of the mask was deteriorated.
Further, since the mask body was made of a soft woven cloth, for example, during a conversation while wearing the mask, the mask body moved up and down with the movement of the mouth, and the mask body gradually slipped off the nose. In particular, in the case of a patient with microtia in which it is difficult to put the ear hook on the ear, this misalignment was remarkable.

Therefore, as a result of diligent research, the inventor provided a shape-retaining member made of an elongated plate piece capable of holding a space in front of the mouth and nose over the entire length in the vertical direction in the middle part in the left-right direction of the mask body. If a slip-preventing member is provided on the upper part of the back side of the middle portion in the left-right direction of the mask body to prevent the mask body from being displaced in the vertical direction while wearing the mask, in particular, by being abutted against the back of the nose. Found that all of them would be resolved, and completed this idea.

The present invention has been made in view of such problems, and when the mask is worn, the woven cloth is sucked by breathing and clings to the mouth, causing suffocation and discomfort, and the appearance of the mask becomes poor. It is an object of the present invention to provide a three-dimensional cloth mask that can prevent vertical displacement including slippage along the back of the nose of the mask body while wearing the mask.

The invention according to claim 1 is a mask body made of a bendable woven cloth and having a cup-shaped central portion, a pair of ear hooks arranged on the left and right sides of the mask body, and the mask. A three-dimensional cloth mask provided at an intermediate portion in the left-right direction of the main body and provided with a shape-retaining member that holds a space in front of the mouth and nose, and the shape-retaining member is intermediate in the left-right direction of the mask body. A deformable elongated tape-shaped plate piece provided on the portion over the entire length in the vertical direction, and is in contact with the upper part of the middle portion in the left-right direction of the mask body on the back side and the upper part of the back of the nose. It is a three-dimensional cloth mask characterized in that a slip-preventing member for preventing a displacement of the mask body in the vertical direction is provided.

The "three-dimensional cloth mask" here is a mask made of woven cloth whose central portion swells like a cup and can be reused by washing with water or the like.
The size of the mask body is not limited. The size for adults (adult men), the size for women, the size for children, etc. are optional.
As the material of the woven fabric, for example, various natural cellulose fibers such as cotton, hemp, wool and pulp can be adopted. In addition, various regenerated cellulose fibers such as rayon, polynosic, and cupra (registered trademark) may be used.

As long as the mask body is bendable and has a cup-shaped bulge in the center, for example, even if it is made of one large-sized woven cloth, a plurality of woven cloth sheets are joined (sewn) together. It may be.
The mask body may be a stack of a plurality of thin woven fabrics in the thickness direction.
The hanging string may be integrally formed with the mask body or may be formed separately.
The material of the hanging string is arbitrary. For example, it may be the same material as the mask body, or it may be a separate body such as a rubber cord.

The material of the shape-retaining member is arbitrary as long as it is deformable. For example, various metals, various synthetic resins, and the like can be adopted.
The shape of the shape-retaining member is arbitrary as long as it is an elongated tape-shaped plate piece.
The size of the shape-retaining member is not limited as long as the length of the shape-retaining member is the same as the length in the vertical direction in the middle portion in the horizontal direction of the mask body.
The thickness of the shape-retaining member is arbitrary. For example, it may be 0.5 mm to 3 mm.
The mounting position of the shape-retaining member is arbitrary as long as it is in the middle portion in the left-right direction of the mask body. For example, it may be the front side or the back side.

"Of the upper part of the middle part in the left-right direction of the mask body, the back side thereof" means the part of the back side of the mask body (inside the mask) that comes into contact with the upper part of the back of the nose when the mask is worn.
The term "slip-off" as used herein means, for example, that the mask body moves up and down with the movement of the mouth during a conversation while wearing the mask, and the mask body gradually slips off along the back of the nose. The anti-slip member is for preventing the mask body from being displaced in the vertical direction including the displacement of the mask body.
The direction for preventing the position of the mask body from being displaced by the displacement prevention member is at least the vertical direction (particularly, the downward direction). For example, it may include not only the vertical direction but also the horizontal direction.
The material of the slip stopper is arbitrary. For example, various fabrics (woven fabrics, non-woven fabrics, etc.), various synthetic resins (particularly those having anti-slip properties such as silicone), various metals, various types of paper, and the like can be adopted.
The shape of the slip stopper is arbitrary. For example, it may be in the form of a sheet, a plate, a line, or a block.
The size of the anti-slip member is arbitrary as long as it can be applied to the back of the nose to prevent the mask body from being displaced in the vertical direction.

The invention according to claim 2 is that the slip-prevention member is a butterfly-shaped ribbon stopper made of a silicone-containing sheet and having a pair of left and right ribbon rings applied to both side surfaces of the upper part of the back of the nose. The three-dimensional cloth mask according to claim 1, which is a feature.

The silicone-containing sheet referred to here is a sheet in which silicone having anti-slip properties is present at least on the surface in contact with the nose. For example, the woven fabric may be treated with a silicone dip, the surface of the woven fabric or paper may be coated with silicone, or a thin silicone sheet may be used.
The length direction (axis axis direction) of each ribbon ring is the vertical direction of the mask body. It is preferable that the ribbon rings are parallel to each other in the axial direction. This is because when the mask body gradually slides down along the back of the nose, the stopper effect of the ribbon rings parallel to each other is enhanced with respect to the back of the nose that gradually spreads downward.
The sphenoid ribbon stopper can be formed, for example, by bending a ribbon made of one silicone-containing sheet. In addition, a pair of left and right ribbon rings formed separately may be combined and formed.

According to the third aspect of the present invention, the mask body has a pair of left and right woven fabric sheets, and the arc-shaped bulging adjacent ends of the woven fabric sheets are placed on one back surface and the other. It is sewn in a state of being overlapped with the surface, and on the back side of the sewn portion of the mask body, a backing cloth made of an elongated woven cloth is provided on the back side of the sewn portion of the mask body to maintain the shape of the sewn portion. The first or second aspect of claim 1, wherein the storage bag portion for storing the member is sewn so as to define the image, and the slip prevention member is provided on the back side of the upper portion of the storage bag portion. It is a three-dimensional cloth mask.

The woven fabric sheet on the left side is the sheet portion on the left side when the mask body is folded in half from the center to the left and right. On the other hand, the woven fabric sheet on the right side is the sheet portion on the right side of it.
The adjacent ends of the woven fabric sheets are bulged in an arc shape so that the central portion of the mask body after stitching becomes a cup shape in a plan view.
The backing cloth may be made of the same material as the mask body or a different material.

According to the first aspect of the present invention, when the mask is worn, the shape-retaining member arranged in the middle portion in the left-right direction of the mask body secures a space in front of the mouth and nose, so that the woven fabric is breathed. It is sucked and clings to the mouth, and you will not feel stuffy or uncomfortable, and the mask will not look bad.
In addition, as the shape-retaining member, a deformable elongated tape-shaped plate piece having a length in the vertical direction is used in the middle portion in the horizontal direction of the mask body, so that the mask can be easily folded in half at the time of storage and the cost is low. It can also be converted.
On the other hand, when the mask is worn, a slip-preventing member provided on the back side of the upper part of the middle portion in the left-right direction of the mask body is brought into contact with the upper part of the back of the nose. Therefore, for example, during a conversation wearing a mask, the mask body moves up and down with the movement of the mouth (particularly, the movement of the lower jaw), and the mask body gradually tries to slip off from the nose. However, the displacement prevention member can prevent the displacement of the mask body in the vertical direction including the displacement. As a result, it becomes a suitable mask for patients with microtia in which the ear hooks hooked on the ears are easily displaced.

In particular, according to the invention according to claim 2, since a sphenoid ribbon stopper made of a silicone-containing sheet having anti-slip properties is used as the slip-preventing member, the left and right sides having appropriate elasticity and cushioning properties when wearing a mask. A pair of ribbon rings are pressed against both sides of the back of the nose.
For example, when the wearer has a conversation in this state, the mask body moves up and down with the movement of the mouth, and the mask body gradually tries to slide down along the back of the nose. However, although each ribbon ring abutting on the left and right sides of the back of the nose is once deformed and pulled in this displacement direction, the displaced mask body is pulled back to the vicinity of the original position due to its shape restoration action. This prevents the mask body from being displaced in the vertical direction, including the displacement of the mask body.
Further, by adopting the sphenoid ribbon stopper made of the silicone-containing sheet in this way, the back of the nose is less likely to hurt even if the mask is worn for a long time, as compared with the case of, for example, a block-shaped anti-slip member.

Further, according to the invention according to claim 3, as the mask main body, the ends of the pair of left and right woven fabric sheets swelling in an arc shape on the adjacent side are overlapped with one back surface and the other front surface. And sewn on the back side of this sewn part with a backing cloth made of an elongated woven cloth over the entire length of the sewn part so as to define a storage bag part for a shape-retaining member with this sewn part. The thing is adopted.
The elongated shape-retaining member is stored in the storage bag portion so that the outer surface is in contact with the back side (back surface) of the sewn portion of the mask body.

By the way, (1) If the shape-retaining member is arranged on the front side of this intermediate portion, a long streak-like ridge appears in the intermediate portion of the mask body by that amount, and the design of the three-dimensional cloth mask is improved. descend. Further, for example, when the adjacent ends of the pair of left and right woven fabric sheets are sewn so as to be in contact with each other in a protruding state to the outside, a streaky ridge higher than this is also obtained. Appears in the middle part of the mask body.
Therefore, here, the arc-shaped bulging adjacent ends of each woven fabric sheet are sewn together with one back surface and the other surface overlapped, and the shape-retaining member is sewn to the middle portion of the mask body. It is provided on the back side of.

(2) Further, the deformable elongated shape-retaining member is appropriately deformed according to the shape of the wearer's nose when each mask is worn. Therefore, if the shape-retaining member is arranged on the back side of the intermediate portion in the left-right direction of the mask body in this way, the outer surface of the shape-retaining member rubs against the back side of the intermediate portion each time the deformation occurs, and the mask is reused. Even when washing repeatedly, the shape-retaining member is pressed against the intermediate portion, so that the portion is likely to be torn. Therefore, here, by suturing the adjacent ends of each woven fabric sheet in a state where one back surface and the other surface are overlapped with each other, the thickness of the intermediate portion is increased to increase the strength. ..

(3) Further, when attaching the shape-retaining member to the back side of the intermediate portion, for example, (a) adhesion, (b) direct sewing of the shape-retaining member to the back side of the central portion using a sewing machine, (c). It is conceivable that an elongated storage bag for a shape-retaining member may be sewn on the back side of the intermediate portion.
Of these, in the cases of (a) and (b), the adhesive may peel off during repeated washing described above or when the shape-retaining member is repeatedly deformed according to the shape of the wearer's nose when wearing a mass. , The sewing thread is liable to fray. Therefore, when attaching the shape-retaining member to the back side of the sewn portion, it is preferable to use the elongated storage bag (c), which does not cause these problems.

Moreover, in the case of this (c), the shape-retaining member does not directly touch the wearer's nose. Therefore, the feel of the mask on the face, especially on the nose, is also good. However, it is not preferable that the storage bag is in the shape of a bag in advance. The reason is that when this is adopted, the outer part of the storage bag is sandwiched between the back side of the sewn part and the shape-retaining member, and the middle part of the mask body is increased by the thickness of this woven cloth. This is because there is a risk that the three-dimensional cloth mask will be streaked outward and spoil the appearance of the three-dimensional cloth mask. Therefore, here, a backing cloth made of an elongated woven cloth is sewn over the entire length of the sewn portion so as to define a storage bag portion for storing the shape-retaining member between the sewn portion (intermediate portion). There is.

Based on the above points, in the present invention of claim 3, the above-described configuration has been adopted in order to simultaneously solve the above-mentioned problems (1) to (3).
That is, in order not to deteriorate the design of the three-dimensional cloth mask, the intermediate portion (sewn portion) in the left-right direction of the mask body is not raised as much as possible, and the intermediate portion is repeatedly washed and repeatedly deformed. Further, the present invention provides a three-dimensional cloth mask that imparts strength to prevent tearing and is suitable for the touch of the three-dimensional cloth mask when worn, particularly the touch between the middle portion in the left-right direction of the mask and the nose.

Further, for example, when a configuration is adopted in which a slip prevention member is directly provided on the upper back side of the middle portion in the left-right direction of the mask body, if there is a defect in the attachment of the slip prevention member, the entire mask body is used. There is a risk that this will have to be discarded. However, in claim 3, since the member to which the slip prevention member is directly attached is the storage bag portion, even if such an unexpected situation occurs, the storage bag portion, which is cheaper than the mask body, can be discarded. It will be possible.

Hereinafter, examples of the present invention will be specifically described with reference to the drawings.

In FIG. 1, reference numeral 10 denotes a three-dimensional cloth mask according to the first embodiment of the present invention. The three-dimensional cloth mask 10 is made of a bendable woven cloth, and has a mask main body 11 having a cup-shaped central portion and a mask main body. It is provided with a pair of ear hooks 12 arranged on both the left and right sides of the mask body 11 and a shape-retaining member 13 provided in the middle portion in the left-right direction of the mask body 11 to hold a space in front of the mouth and nose. ..

As shown in FIGS. 1 and 2, when worn, the mask body 11 includes the surfaces of the nasal cavity and maxillary sinus, and covers the entire face from the chin to the mouth, the nose, and the cheeks on both the left and right sides thereof. A sheet made of synthetic fibers of 82% polyester and 18% polyurethane having a size and size.
The mask main body 11 has a left woven fabric sheet 14 which is an intermediate left half in the left-right direction, and a right woven fabric sheet 15 which is the remaining right half. The ends of the left and right woven fabric sheets 14 and 15 on the adjacent sides (center side of the mask) are sewn together (hereinafter, this is referred to as a sewn portion a) and bulge in an arc shape when viewed from the side.
The pair of left and right ear hooks 12 are woven fabrics whose tips are substantially semi-elliptical, and are integrally formed of the same material at the outer ends of the woven fabric sheets 14 and 15 on which the base ends correspond to each other. Has been done. Each ear hook portion 12 is provided with a horizontally long elliptical ear hook hole 16.

As shown in FIG. 1, on the back side of the sewn portion a of the mask main body 11, a backing cloth 17 made of an elongated woven cloth (width of about 1 cm) is held between the sewn portion a and the sewn portion a over the entire length of the sewn portion a. It is sewn so as to define the storage bag portion 18 for storing the shape member 13. The backing cloth 17 is longer than the length of the stitched portion a.
The shape-retaining member 13 is an elongated, bendable synthetic resin tape in which a metal wire (not shown) is embedded as a core material. The thickness of the shape-retaining member 13 is 0.8 mm.

Further, as shown in FIGS. 1 and 6, the back side (inside the mask) of the upper part of the storage bag portion 18 is brought into contact with the upper part of the back of the nose of the wearer to cause the mask body 11 to be displaced in the vertical direction. A butterfly-shaped stopper (slip prevention member) 30 for preventing is provided.
The butterfly-shaped ribbon stopper 30 is formed by bending a ribbon R (made of a silicone-containing sheet) made of a woven cloth into a butterfly blade shape (see also FIG. 2).
The sphenoid ribbon stopper 30 is composed of the ribbon R, and has a pair of left and right parallel ribbon rings 31 that are applied to both side surfaces of the upper part of the back of the nose.
The size of the ribbon R is about 5 cm in length, about 2 cm in width, and about 0.1 mm in thickness.
Further, each ribbon ring 31 has a diameter of about 7 mm whose axis extends in the vertical direction of the mask body 11.

Here, a method of manufacturing the three-dimensional cloth mask 10 will be described with reference to FIGS. 1 to 5.
The left side woven cloth sheet 14, the right side woven cloth sheet 15, the back cloth 17, the shape-retaining member 13, and one ribbon R are prepared in advance (see FIG. 2).
First, the adjacent ends of the left and right woven fabric sheets 14 and 15 are sewn with a sewing machine in a state where one back surface and the other front surface are overlapped to form the mask body 11 (see FIG. 3). ).

After that, a backing cloth 17 having both ends in the length direction folded inward is formed on the back side of the sewn portion a of the mask body 11, and a storage bag portion 18 for a shape-retaining member is defined between the sewn portion a and the back cloth 17. (See FIGS. 4 and 5). At this time, one end of the backing cloth 17 in the length direction is not sewn and is released.
Next, the shape-retaining member 13 is inserted into the storage bag portion 18 from the open portion b, and then the open end of the backing cloth 17 is sewn to the stitched portion a. As a result, the shape-retaining member 13 is enclosed in the storage bag portion 18.

Next, as shown in FIG. 6, a sphenoid stopper 30 is provided on the back side of the upper portion of the storage bag portion 18 using one ribbon R. Specifically, after sewing one end of the ribbon R in the length direction to one end in the width direction on the upper back side of the storage bag portion 18, the ribbon R is sewn on the other end in the width direction on the upper back side of the storage bag portion 18. Sew the other end in the length direction of. After that, the intermediate portion in the length direction of the ribbon R is sewn to the intermediate portion in the width direction on the upper back side of the storage bag portion 18. These three sewing lines are parallel to each other. Further, at each sewing, the sewn portion a of the mask body 11 is also sewn integrally. In this way, the three-dimensional cloth mask 10 is produced (see FIG. 1).

Next, a method of wearing the three-dimensional cloth mask 10 of the first embodiment will be described with reference to FIG. 7.
As shown in FIG. 7, when using the three-dimensional cloth mask 10, each ear hook portion 12 is hooked on the left and right ears with the sphenoid ribbon stopper 30 pressed against the upper part of the back of the nose. As a result, the mask body 11 covers the entire surface of the nasal cavity and maxillary sinus, from the chin to the mouth, the nose, and the cheeks on both the left and right sides thereof. At this time, a pair of left and right ribbon rings 31 are pressed against both side surfaces of the upper part of the back of the nose.
After that, while appropriately deforming the shape-retaining member 13 with the fingertips, a space for relieving suffocation is secured in front of the mouth and nose.

As described above, when the three-dimensional cloth mask 10 is worn, a space is secured in front of the mouth and nose by the shape-retaining member 13 arranged at the intermediate portion in the left-right direction of the mask main body 11. Therefore, the woven cloth of the mask body 11 is sucked by breathing and clings to the mouth, and the suffocation and discomfort are not felt, and the appearance of the three-dimensional cloth mask 10 is not deteriorated.
Further, as the shape-retaining member 13, a deformable elongated plate piece having a length in the vertical direction is adopted in the middle portion in the horizontal direction of the mask main body 11, so that the three-dimensional cloth mask 10 can be easily folded in half during storage. Cost reduction can also be achieved.

Further, in the three-dimensional cloth mask 10, since the butterfly-shaped ribbon stopper 30 is provided on the upper part of the middle portion in the left-right direction of the mask main body 11, the mask main body 11 is less likely to slip off while wearing the mask. As a result, it becomes a suitable mask for patients with microtia in which the ear hook portion 12 hooked on the ear is easily displaced.
Furthermore, since the sphenoid ribbon stopper 30 is made of a silicone-dipped ribbon R, it has sufficient anti-slip properties for the pair of left and right ribbon rings 31 despite being an inexpensive and lightweight anti-slip member. As well as obtaining appropriate elasticity, cushioning property and high shape restoration property.
For example, when the wearer has a conversation while wearing the mask, the mask body 11 moves up and down with the movement of the mouth (particularly, the movement of the lower jaw), and the mask body 11 gradually slides down along the back of the nose. Try to. However, although each ribbon ring 31 abutted on the left and right sides of the back of the nose is once deformed and pulled in this displacement direction, the mask body 11 is pulled back to the vicinity of the original position by the shape restoration action. This prevents the mask body 11 from being displaced in the vertical direction, including slipping off. Further, since the axes of the ribbon rings 31 are parallel to each other, the stopper effect on the back of the nose is generally enhanced when the mask body 11 gradually shifts along the back of the nose that spreads downward.

Further, since the sphenoid ribbon stopper 30 is used as the slip stopper here, the back of the nose becomes painful even if the three-dimensional cloth mask 10 is worn for a long time, as compared with the case where the block-shaped slip stopper is used, for example. Hateful.
Further, since the butterfly-shaped ribbon stopper 30 is provided on the back side of the upper part of the storage bag portion 18, for example, the butterfly-shaped ribbon stopper 30 may be sewn to the storage bag portion 18 after being sewn to the mask body 11 in this way. If the butterfly-shaped ribbon stopper 30 is sewn on the back side of the upper part of the backing cloth 17 in advance, even if there is a defect in the sewing of the butterfly-shaped ribbon stopper 30, it is necessary to discard the entire mask body 11. It is also possible to dispose of the backing cloth 17 which is cheaper than the mask main body 11.
Furthermore, an ear strap hook made of a rubber band or the like is placed on the back of the head (not shown), and a pair of left and right ear hooks 12 are hooked on the ear hooks to eliminate pain in both ears when wearing a mask. May be good. In this case as well, the mask body 11 may slip off due to the movement of the mouth while wearing the mask.

By the way, here, as the mask main body 11, the ends of the pair of left and right woven fabric sheets 14 and 15 on the adjacent sides bulging in an arc shape are sewn together with one back surface and the other surface overlapped. On the back side of the sewn portion a, a backing cloth 17 made of an elongated woven cloth was sewn over the entire length of the sewn portion a so as to define a storage bag portion 18 for the shape-retaining member 13 with the sewn portion a. The thing is adopted. The elongated shape-retaining member 13 is housed in the storage bag portion 18 so that the outer surface is in contact with the back side (back side) of the sewn portion a of the mask body 11.

(1) If the shape-retaining member 13 is arranged on the front side of the intermediate portion, a long vertical ridge appears in the intermediate portion of the mask body 11 by that amount, and the design of the three-dimensional cloth mask 10 is improved. Decreases. Further, for example, even when the adjacent ends of the pair of left and right woven fabric sheets are sewn so that the back surfaces of the woven fabric sheets come into contact with each other in an outward protruding state, a streak-like ridge higher than this is formed on the mask body. Appears in the middle part of.
Therefore, in this three-dimensional cloth mask 10, the arc-shaped bulging adjacent ends of the woven cloth sheets 14 and 15 are sewn together with one back surface and the other surface overlapped with each other, and the shape is retained. The member 13 is provided on the back side of the intermediate portion of the mask main body 11.

(2) Further, the deformable elongated shape-retaining member 13 is appropriately deformed according to the shape of the wearer's nose when each mask is worn. Therefore, if the shape-retaining member 13 is arranged on the back side of the intermediate portion in the left-right direction of the mask body 11 in this way, the outer surface of the shape-retaining member 13 is rubbed against the back side of the intermediate portion each time the mask body 11 is deformed, and the mask body 13 is reused. Therefore, even when the three-dimensional cloth mask 10 is repeatedly washed, the shape-retaining member 13 is pressed against the intermediate portion many times, so that the portion is likely to be torn. Therefore, here, the intermediate portions of the mask main body 11 are thickened by suturing the adjacent ends of the woven fabric sheets 14 and 15 in a state where one back surface and the other front surface are overlapped with each other. To increase the strength.

(3) Further, when the shape-retaining member 13 is attached to the back side of the intermediate portion, for example, (a) adhesion, (b) direct sewing of the shape-retaining member 13 to the back side of the central portion using a sewing machine, ( c) On the back side of this intermediate portion, an elongated storage bag for the shape-retaining member 13 may be sewn.
Of these, in the cases of (a) and (b), the adhesive is peeled off during repeated washing described above or when the shape-retaining member 13 is repeatedly deformed according to the shape of the wearer's nose when wearing a mass. Also, the sewing thread is likely to fray. Therefore, when attaching the shape-retaining member 13 to the back side of the sewn portion a, it is preferable to use the elongated storage bag (storage bag portion 18) of (c), which does not cause these problems.

Moreover, in the case of this (c), the shape-retaining member 13 does not directly touch the wearer's nose. Therefore, the feel of the mask on the face, especially on the nose, is also good. However, it is not preferable that the storage bag is in the shape of a bag in advance. The reason is that when this is adopted, the outer portion of the storage bag is sandwiched between the back side of the sewn portion a and the shape-retaining member 13, and the mask body 11 is made by the thickness of this woven cloth. This is because the intermediate portion may be raised outward in a streak pattern, which may impair the appearance of the three-dimensional cloth mask 10. Therefore, here, the back cloth 17 made of an elongated woven cloth is defined as the storage bag portion 18 for storing the shape-retaining member 13 with the sewn portion (intermediate portion) a over the entire length of the sewn portion a.
