Description

The present invention relates to a three-dimensional cloth mask, specifically a three-dimensional cloth mask having a mask body made of a bendable 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 can catch the virus. 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.

Therefore, as a result of diligent research, the inventor solved all the above-mentioned problems by providing a shape-retaining member in front of the mouth and nose at the joint of the woven cloth sheet in the mask body. 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. The purpose is to provide a three-dimensional cloth mask that never happens.

The invention according to claim 1 includes a mask body made of a bendable woven cloth and having a cup-shaped central portion, and a pair of ear hooks arranged on both left and right sides of the mask body. The three-dimensional cloth mask is a three-dimensional cloth mask characterized in that a shape-retaining member for holding a space is provided in front of the mouth and nose at an intermediate portion in the left-right direction of the mask body.

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. For example, various metals, various synthetic resins, and the like can be adopted. The shape-retaining member may be a rigid body or a soft material.
The shape of the shape-retaining member is arbitrary. For example, it may be elongated plate-shaped, circular or oval-shaped.
The size of the shape-retaining member is also not limited. For example, the length of the shape-retaining member may be the same as or shorter than the length in the vertical direction in the intermediate portion in the horizontal direction of the mask body, for example.
The thickness of the shape-retaining member is arbitrary. For example, it may be 0.5 mm to 3 mm.

According to the second aspect of the present invention, the shape-retaining member is a deformable elongated tape-shaped plate piece, and the length of the shape-retaining member is the vertical length of the intermediate portion in the left-right direction of the mask body. The three-dimensional cloth mask according to claim 1, which is the same.

As the shape-retaining member which is a deformable elongated tape-shaped plate piece, for example, various soft synthetic resin tapes and the like can be adopted. In addition, various metal tapes such as aluminum tape and iron tape may be used.
The degree of "deformability of the shape-retaining member" here means, for example, the degree of easy deformation by the force of a fingertip.

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 with the sewn portion. The three-dimensional cloth mask according to claim 2, wherein the storage bag portion for storing the members is sewn so as to define the image.

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.

The invention according to claim 4, wherein a filter sheet is provided inside the mask body so as to be hooked on the backing cloth via a hook-and-loop fastener. , The three-dimensional cloth mask according to any one of the above.

The hook-and-loop fastener is optional as long as it can be hung on the backing cloth. For example, a male hook-and-loop fastener having a large number of minute hooks may be used. Alternatively, either one of the male hook-and-loop fastener and the female hook-and-loop fastener may be attached to the inside of the backing cloth, and the remaining one may be attached to the outside of the filter sheet.
The material of the filter sheet is arbitrary. For example, woven cloth, non-woven fabric, paper, sponge and the like may be used.
The shape and size of the filter sheet are arbitrary as long as they can capture the droplets contained in the exhaled breath when wearing the mask.

According to the invention according to claim 1, 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 particular, according to the invention according to claim 2, since a deformable elongated tape-shaped plate piece having a length in the vertical direction is adopted as the shape-retaining member in the middle portion in the horizontal direction of the mask body, it is stored. Sometimes it is easy to fold the mask in half and the cost can be reduced.

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, a backing cloth made of an elongated woven cloth was sewn 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. Also,
The present invention provides a three-dimensional cloth mask that imparts strength to prevent tearing and is particularly suitable for the touch of the three-dimensional cloth mask when worn, particularly between the middle portion in the left and right directions of the mask and the nose.

In the device according to claim 4, a filter sheet is hung on a backing cloth inside the mask body via a hook-and-loop fastener. Therefore, when the mask is worn, droplets during sighing are captured by the filter sheet, and the dirt on the mask body can be reduced.

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, the mask body 11 has a shape that includes the surfaces of the nasal cavity and the maxillary sinus when worn, 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 cloth sheet 14 which is an intermediate left half in the left-right direction, and a right woven cloth 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) bulge in an arc shape in a plan view.
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 is housed between the sewn portion a and the shape-retaining member 13 over the entire length of the sewn portion a. It is sewn so as to define the storage bag portion 18. 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.

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, and the shape-retaining member 13 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 drawn on the back side of the sewn portion a of the mask body 11, and a storage bag portion 18 for the shape-retaining member 13 is drawn between the sewn portion a and the back cloth 17. Sew to form (see FIGS. 4 and 5). At this time, one end of the backing cloth 17 in the length direction is not sewn and is left open.
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 to produce the three-dimensional cloth mask 10 (see FIG. 1).

Next, a method of using the three-dimensional cloth mask 10 of the first embodiment will be described with reference to FIG.
As shown in FIG. 5, when using the three-dimensional cloth mask 10, similarly to the general-purpose mask, each ear hook portion 12 is hooked on the left and right ears, and the sewn portion a of the mask body 11 is hung via the back cloth 17. The mask body 11 covers the entire face from the jaw to the mouth, the nose, and the cheeks on both the left and right sides thereof, including the surfaces of the nasal cavity and the maxillary sinus, with the mask body 11 in contact with 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, in the three-dimensional cloth mask 10 of the first embodiment, when the mask is worn, the shape-retaining member 13 arranged in the middle portion in the left-right direction of the mask main body 11 secures a space in front of the mouth and nose. The woven cloth of the mask body 11 is sucked by breathing and clings to the mouth without feeling stuffy or uncomfortable, and the appearance of the three-dimensional cloth mask 10 does not deteriorate.
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.

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. A backing cloth 17 made of an elongated woven cloth was sewn on the back side 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 over the entire length. 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.

By the way, (1) If the shape-retaining member 13 is arranged on the front side of the intermediate portion, a long streak-like ridge appears in the intermediate portion of the mask main body 11 by that amount, and the three-dimensional cloth mask 10 The design is reduced. 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. Is sewn on.

Based on the above points, in the three-dimensional cloth mask 10 of the first embodiment, the above-mentioned configuration is adopted in order to solve the above-mentioned problems (1) to (3) at the same time.
As a result, in order not to deteriorate the design of the three-dimensional cloth mask 10, the intermediate portion (sewn portion a) in the left-right direction of the mask main body 11 is not raised as much as possible, and the adjacent ends of the left and right woven cloth sheets are separated from each other. By superimposing, it is possible to give the intermediate portion a strength that does not easily tear even if the shape-retaining member 13 is repeatedly washed or deformed, and the touch of the three-dimensional cloth mask 10 when worn, especially the left side of the mask. ， The touch between the middle part in the right direction and the nose can also be suitable.

Next, the three-dimensional cloth mask according to the second embodiment of the present invention will be described with reference to FIG.
As shown in FIG. 6, the feature of the three-dimensional cloth mask 10A of the second embodiment is that the filter sheet 31 is detachably provided inside the mask main body 11.

The filter sheet 31 has a shape similar to that of the mask body 11 and is smaller than this.
The filter sheet 31 may be made of a disposable non-woven fabric or a woven cloth that can be reused by washing.
A male hook-and-loop fastener 30 is sewn on the central portion of the front side of the filter sheet 31.

When using the three-dimensional cloth mask 10A of the second embodiment, the male hook-and-loop fastener 30 is hooked on the back cloth 17 in advance, and the filter sheet 31 is attached to the back side of the mask main body 11 in a stretched state. In this state, the three-dimensional cloth mask 10A is worn in the same manner as in the case of the first embodiment.
When wearing the mask, droplets during breathing are mainly captured by the filter sheet 31. As a result, dirt on the mask body 11 can be reduced.
When the filter sheet 31 becomes dirty, only the filter sheet 31 can be replaced.
Since other configurations, actions, and effects are substantially the same as those in the first embodiment, the description thereof will be omitted.

The present invention is useful as a technique for a three-dimensional cloth mask having a mask body made of a bendable woven cloth.
