Description

TECHNICAL FIELD The present invention relates to a mask that can prevent the wearing position from slipping due to opening and closing of the mouth.

2. Description of the Related Art The use of masks is increasing for the prevention of infectious diseases, hay fever, and the like, and in recent years, many disposable masks made of nonwoven fabric have been distributed. The reasons for this are that, compared to gauze masks, masks made of nonwoven fabric can ensure high filter performance, can be mass-produced, and are inexpensive to manufacture. .
Many of the masks made of this nonwoven fabric have a plurality of pleats along the left-right direction of the mask body.

FIG. 30 shows an example of a mask 31 disclosed in Patent Document 1. A mask main body 32 formed in a laterally long shape (rectangular shape) by overlapping a plurality of nonwoven fabrics has a plurality of slits along the left-right direction. of pleats 33 are applied. Between the upper corners A1 and the lower corners A2 on the left and right sides of the mask body 32, one end and the other end of an ear hook string 34 formed in a string shape from rubber or elastic fiber material are provided. The ends are attached to each other, for example by heat welding or ultrasonic welding.
A nose reinforcing member (nose fit) 35 made of, for example, a plastic wire is inserted and attached along the upper edge of the mask body 32 .

According to the configuration of the mask 31 described above, when the mask 31 is attached to the front of the wearer's face using the left and right ear straps 34, the plurality of pleats 33 applied to the mask main body 32 extend in the vertical direction ( up and down). Patent Literature 1 describes that this allows the mask 31 to have a three-dimensional effect and improves the wearability of the mask 31 .

JP 2011-182810 A

By the way, in the mask 31 shown in FIG. 30, although the mask main body 32 is provided with the expandable cushioning body called the pleats 33, the wearing position of the mask 31 can be changed by, for example, repeatedly opening and closing the mouth. There is a problem that it slides down.
31 and 32 show the mask 31 disclosed in Patent Literature 1 as it is worn on the front face of the wearer. As shown in FIG. 31, the upper end of the mask body 32 covers the back of the nose h1 of the face, the lower end of the mask body 32 covers the top of the lower jaw h2, and the left and right ear hook straps are attached to the mask 31 as shown in FIG. 34 are worn by hanging them on the ears.

In this case, the tension B1 by the upper ear strap 34a stretched between the upper corner A1 of the mask main body 32 and the wearer's ear pulls the upper end of the mask main body 32 toward the ear toward the wearer's face. acts like In addition, the tension B2 by the lower ear strap 34b stretched between the lower corner A2 of the mask body 32 and the wearer's ear is drawn from a position beyond the top h2 of the lower jaw toward the ear. works. Therefore, the mask main body 32 is always in a state where a force B3 is exerted downward via the top h2 of the lower jaw.

Then, as indicated by an arrow B4 in FIG. 32 , when the wearer lowers the lower jaw by opening the mouth, the lower end of the mask body 32 wraps around the top h2 of the lower jaw. is easy to work with. Also, when the mandible is raised by closing the mouth, the top h2 of the mandible moves in the opposite direction to the above-described winding, and in this case, the action of raising the mask body 32 is difficult.

Therefore, when the mouth is repeatedly opened and closed, the pleats 34 are repeatedly stretched and contracted, but the upper end of the mask body 32 gradually moves downward from the nose back h1 to expose the nose.
In particular, when the user utters a loud voice, such as when singing in chorus or cheering, a large opening and closing movement of the mandible is involved, which significantly causes the problem that the wearing position of the mask body 32 slips down.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a mask capable of solving the problem that the mask body is displaced from its mounting position when the mouth is opened or closed.

A mask according to the present invention, which has been made to solve the above-described problems, is a mask comprising a mask body covering the mouth and nose, and ear straps for pulling the mask body to the face, wherein the left and right sides of the mask body are Pulling members for pulling up the lower corner A2 toward the left and right upper corners A1 of the mask body are arranged between the upper corner A1 and the lower corner A2, respectively. characterized by being

In this case, in one preferred embodiment, the ear strap is formed of an elastic member that can stretch and contract, and one end of the ear strap is connected to the upper corner A1, and the ear strap is connected to the upper corner A1. The other end is connected to the lower corner A2, and the intermediate portion of the ear strap is connected to the upper corner A1, so that the intermediate portion of the ear strap is connected to the lower corner. A configuration is adopted in which a part of the ear strap extending to A2 is used as the pulling member.

Furthermore, a configuration in which a hook member is attached to the intermediate portion of the ear strap, and the intermediate portion of the ear strap is connected to the upper corner portion A1 via the hook member may also be preferably adopted. can.

On the other hand, one end and the other end of the ear strap are connected to the upper corner A1 in a loop shape, and between the upper corner A1 and the lower corner A2, It is also possible to employ a configuration in which the lifting member formed in a belt shape from a stretchable material or a flexible non-stretchable material is arranged.

According to the mask according to the present invention described above, the lifting members for lifting the left and right lower corners A2 of the mask body covering the mouth and nose toward the left and right upper corners A1 of the mask body are provided in the upper corners. They are respectively arranged between the corner A1 and the lower corner A2. A part of the ear strap made of an elastic member, for example, can be used as the pull-up member.

As a result, even after the wearer opens and closes his/her mouth widely, the lifting member using a part of the ear strap immediately pulls the lower corner A2 of the mask body toward the upper corner A1. can be given a pulling action.
Therefore, it is possible to provide a mask that can solve the problem that the wearing position of the mask body slips due to large opening and closing movements of the lower jaw accompanying singing, cheering, and the like.

A mask according to the present invention will be described based on an embodiment shown in the drawings.
1 and 2 show the mask of the first embodiment according to the present invention, of which FIG. 1 shows the right half of the half-finished mask.
The mask 1 shown in FIG. 1 has a mask main body 2 formed in a laterally long shape (rectangular shape) by superimposing a plurality of nonwoven fabrics. It has 3 pleats. That is, the plurality of pleats 3 are formed by performing pleat processing in a state in which a plurality of nonwoven fabrics described above are superimposed.

Between the upper corners A1 and the lower corners A2 on the left and right sides of the mask main body 2, one end of a thermoplastic ear hook string 4 formed like a string from rubber or an elastic fiber material is provided. and the other end are respectively attached by, for example, heat welding or ultrasonic welding.
Furthermore, in the mask 1 of the first embodiment, the intermediate portion A3 of the ear strap 4 near the lower corner A2 of the ear strap 4 is thermally welded or super-welded to the upper corner A1. By connecting them simultaneously by sonic welding, the ear strap 4 is connected in a loop shape at the upper corner A1 as shown in FIG.
A portion of the ear strap 4 extending from the intermediate portion A3 to the lower corner A2 is connected between the upper corner A1 and the lower corner A2, and is connected to the lower corner A2. toward the upper corner A1.

In this case, as shown in FIG. 1, the dimension between the intermediate portion A3 and the lower corner portion A2 of the ear strap 4 in the state where no pulling force is applied is L1, and the pleats 3 of the mask body 2 are set to L1. Assuming that the dimension between the upper corner A1 and the lower corner A2 in the folded flat state is L2, it is desirable to set L1<L2.
Reference numeral 5 shown in FIG. 1 indicates a nose reinforcing member (nose fit) made of, for example, a plastic wire inserted along the upper end of the mask body 2 .

FIG. 2 is a side view showing a state in which the mask of the first embodiment constructed as described above is worn.
According to this mask 1, the upper end of the mask body 2 can cover the back of the nose h1 of the wearer, and the lower end of the mask body 2 can cover the apex h2 of the lower jaw. In this state, the mask 1 is attached to the front of the face by hooking the ear string 4 attached to the upper corner A1 in a loop shape to the ear.
When the mask 1 is worn, the pull-up member 6 formed by part of the ear strap 4 pulls the lower corner A2 of the mask body 2 toward the upper corner A2. Always act to pull up.

According to the mask 1 of the first embodiment, when the wearer lowers the lower jaw, the lower part of the mask main body 2 wraps around the top h2 of the lower jaw, and the lower part of the mask main body 2 spreads the pleats 3 to accommodate the movement of the lower jaw. descend along. On the other hand, when the wearer raises the lower jaw, the lower part of the mask main body 2 rises while being wrapped around the top h2 of the lower jaw under the pulling action of the lifting member 6, and the pleats 3 are accordingly closed. do.
Therefore, the lower part of the mask body 2 always follows the movement of the lower jaw, thereby solving the problem that the mask body 2 is displaced from the mounting position.

The mask main body 2 is usually formed by stacking two to three layers or more of non-woven sheet materials. At least one of these layers is a high-density non-woven fabric produced by the meltblown method. The meltblowing method is a melt-spinning method in which a raw material resin is made into a nonwoven fabric in one step. Thermoplastic resin melted in an extruder is passed through a die with several hundred to more than 1,000 nozzles per 1m in the width direction, and high-temperature, high-speed airflow is used to create filaments. , and the fibrous stretched resin is accumulated on the conveyor. At that time, the fibers are entangled and fused together to form a web of self-adhesive ultrafine fibers with no binder.

The mask body 2 shown in the figure has a first layer 2a constituting the inside of the mask body 2 and a second layer 2b constituting the outside as a basic structure, as shown in a partially enlarged cross-sectional view in FIG. is doing.
The inner first layer 2a is a nonwoven fabric having a high fiber density and mainly performing a filter function, and the outer second layer 2b is a bulky nonwoven fabric having a lower fiber density than the first nonwoven fabric.
In addition, it is desirable to form a mask body of three or more layers of nonwoven fabric by further overlapping the wearer-side fabric 2c made of nonwoven fabric located on the wearer's side on the inner side of the first layer 2a that functions as a filter.

Since the nonwoven fabric that mainly functions as a filter and constitutes the first layer 2a needs to play a role in collecting dust, pollen, and infectious viruses, a nonwoven fabric with high collection efficiency, preferably polypropylene A meltblown nonwoven fabric made of resin, having fine fibers with an average fiber diameter of 0.1 to 10 μm, and having a basis weight of 5 to 20 g/m ² and having a high fiber density is preferably used. The average fiber diameter is a numerical value obtained by measuring the diameters in the fiber at arbitrary 30 points from an observation image of a scanning electron microscope (SEM) and averaging the measured diameters.

As the resin material of the meltblown nonwoven fabric forming the first layer 2a, polyethylene, polyethylene terephthalate, polyurethane, polyester, etc. can be suitably used in addition to the polypropylene resin described above.

More preferably, long-fiber polyester with an average fiber diameter of 3 μm or less is used to prevent deterioration of the material due to ultraviolet rays and improve heat radiation performance, thereby reducing heat build-up inside the mask body 2 . . In addition, the long-fiber polyester may be formed as a separate layer from the first layer.
Further, one surface of the nonwoven fabric layer may be adjacent to a woven fabric layer made of polyester long fibers, and the fibers in contact with each other may be in a fused state.
Furthermore, the non-woven fabric layer and the fabric layer may be sewn together with a fabric layer of yarn or a knitted fabric layer of yarn.

The nonwoven fabric forming the second layer 2b is a nonwoven fabric using a polyolefin resin material. It is desirable that the polyolefin-based nonwoven fabric constituting the second layer 2b has a lower fiber density and a higher bulk than the nonwoven fabric of the first layer 2a that functions as a filter.
That is, it is preferable that the nonwoven fabric constituting the second layer 2b has an average fiber diameter of 50 to 200 μm and a basis weight equal to or less than that of the first layer even if the nonwoven fabric is bulkier than the first layer. For the production of the second layer, a spunbond production device is used, and the thermoplastic resin melted in the extruder is used, for example, using a nozzle with a larger diameter and a smaller number than when producing the first layer, and a high-temperature, high-speed air flow. It is assumed that the molecular arrangement is arranged by the stretching effect of.

Examples of the polyolefin resin constituting the second layer 2b include high-density polyethylene resin, medium-density polyethylene resin, low-density polyethylene resin, linear low-density polyethylene resin, polypropylene resin, ethylene-propylene copolymer, ethylene-butene- 1 copolymer, ethylene-pentene-1 copolymer, ethylene-hexene-1 copolymer, ethylene-octene-1 copolymer, ethylene-vinyl acetate copolymer, ethylene-(meth)acrylate copolymer Copolymers, ethylene-vinyl chloride copolymers, ethylene-propylene-butene copolymers, and the like can be mentioned, and high-density polyethylene resins and polypropylene resins are particularly preferably used.
The second layer 2b is isotactic polypropylene: 1 to 40 parts by weight, 45 to 89 mol% of propylene, 10 to 25 mol% of ethylene, and an α-olefin having 4 to 20 carbon atoms; A polypropylene resin containing 60 to 99 parts by weight of a propylene/ethylene/α-olefin copolymer consisting of (however, the amount of the α-olefin having 4 to 20 carbon atoms copolymerized does not exceed 30 mol%) Fibers obtained by manufacturing and spinning the composition and fibers composed of other resins whose main component is a propylene random copolymer containing ethylene of 10% by weight or less, or composed of a mixture of propylene homopolymer and high-density polyethylene and a nonwoven fabric having a residual strain of less than 50% after being drawn at a draw ratio of 150%.

It should be noted that the mask main body 2 that is gentle on the skin can be made by using a blend of polyester fibers for the cloth 2c on the wearer's side.
As a result, it is possible to provide the mask 1 which can improve heat retention in the mask main body 2, which dries well after washing, and which hardly shrinks.
In addition, polyester fibers are much less susceptible to deterioration by ultraviolet rays than polypropylene, which is often used in conventional non-woven masks, so they can be sterilized by drying in the sun.

Moreover, it is preferable that the nonwoven fabric of each layer contains a component having antibacterial and antiviral properties. The component having antibacterial and antiviral properties is preferably at least one compound selected from the group consisting of palmityldiethanolamine and stearyldiethanolamine.
As the component having antibacterial and antiviral properties, palmityldiethanolamine or stearyldiethanolamine may be used alone, or a mixture thereof may be used. Palmityldiethanolamine is an alkyldiethanolamine having a palmityl group, which is a long-chain alkyl group having 16 carbon atoms. Stearyldiethanolamine is an alkyldiethanolamine having a stearyl group with 18 carbon atoms.
Stearyldiethanolamine and palmityldiethanolamine have relatively higher melting points than myristyldiethanolamine and lauryldiethanolamine. Therefore, stearyldiethanolamine and palmityldiethanolamine are relatively difficult to volatilize during, for example, melt molding of the polyethylene layer, particularly during heat setting when the polyethylene layer is a stretched film. Moreover, stearyldiethanolamine and palmityldiethanolamine are excellent in antibacterial performance and antiviral performance. Furthermore, the nonwoven fabric of the present invention is relatively slow in transferring to contact objects, is excellent in safety, and can maintain its performance.
(Alkyldiethanolamine; number of carbon atoms in long-chain alkyl group; melting point)
Stearyldiethanolamine; 18 pieces; 51°C
Palmityldiethanolamine; 16 pieces; 28°C
Myristyldiethanolamine; 14; 22-23°C
Lauryldiethanolamine; 12 pieces; liquid at room temperature

Each component may also contain analogous compounds individually. For example, palmityldiethanolamine (16 carbon atoms) may contain a small amount of myristyldiethanolamine (14 carbon atoms) or an alkyldiethanolamine having an alkyl group of 12 to 20 carbon atoms such as stearyldiethanolamine (18 carbon atoms). Also, stearyldiethanolamine (18 carbon atoms) may contain a small amount of alkyldiethanol having an alkyl group of 16 to 20 carbon atoms, for example. Ingredients having antibacterial and antiviral properties may also contain small amounts of compounds in which a portion of the amines of these analogous compounds of palmityldiethanolamine and stearyldiethanolamine are esterified with aliphatic carboxylic acids. Compounds analogous to these components having antibacterial and antiviral properties are generally synthesized at the same time in the steps of synthesis and separation of components having antibacterial and antiviral properties, or are difficult to separate. Moreover, the similar compound is preferably less than 50 parts by mass with respect to 100 parts by mass of the component having antibacterial and antiviral properties.

The nonwoven fabric contains 0.1 to 100 mg/m ² as a surface amount, preferably 0.4 to 50 mg/m ² . Examples of the method for making the surface amount of the component having antibacterial and antiviral performance in the nonwoven fabric include spraying the component on the surface of the nonwoven fabric, or preparing a solution or suspension containing the component on the surface. A coating method such as applying a Moreover, the said component may exist on the surface by making the said component bleed out to the said nonwoven fabric by making the layer other than the said nonwoven fabric contain the said component. Further, after kneading the components in advance in the material constituting the nonwoven fabric in an extrusion process, a thermoplastic process, or the like, the material kneaded with the components may be formed into the nonwoven fabric. The amount (total content) of the component in the nonwoven fabric of the present invention is preferably 0.01 to 1% by weight, and 0.01 to 1% by weight, from the viewpoint of allowing the component to bleed out to the surface in the above range. 02 to 0.8% by mass is more preferable.
The components having antibacterial and antiviral properties described above can also be similarly employed in each mask after the second embodiment described below.

FIG. 3 is a side view showing the mask of the second embodiment in a worn state.
The mask 1 of the second embodiment is the half-finished mask 1 shown in FIG. A structure in which the intermediate portion A3 of the ear strap 4 is connected to the upper corner portion A1 of the mask body 2 via the hook member 7 is adopted.
In the illustrated example, the hook member 7 attached to the intermediate portion A3 of the ear strap 4 is engaged with the root portion of the ear strap 4 connected to the upper corner A1 of the mask body 2. As shown in FIG. As a result, a configuration in which the intermediate portion A3 of the ear strap 4 is substantially connected to the upper corner portion A1 of the mask body 2 is adopted.
The structure other than the use of the hook member 7 is the same as that of the mask 1 of the first embodiment shown in FIG. 2, and the parts corresponding to the parts shown in FIG. are omitted.

According to the mask 1 having this configuration, the ear strap 4 extending from the upper corner A1 of the mask body 2 to the intermediate portion A3 to which the hook member 7 is attached is substantially looped around the upper corner A1. After being attached, the mask 1 is worn on the front of the face by hooking the loop-shaped ear straps 4 to the ears.
The elastic action of the ear strap 4 between the hook member 7 and the lower corner A2 of the mask body 2 pushes the lower corner A2 of the mask body 2 toward the upper corner A2. It functions as a pulling member 6 that always pulls up.

Therefore, in the mask 1 of the second embodiment shown in FIG. 3 as well, effects similar to those of the mask 1 of the first embodiment shown in FIG. 2 can be obtained.
Also, in the mask body 2 of the mask 1 of the second embodiment, similar to the mask 1 of the first embodiment, a plurality of layers of melt-blown nonwoven fabrics are superimposed and molded to obtain the same effects. can be done.

FIG. 4 shows a preferred example of the hook member 7 used in the mask 1 of the second embodiment shown in FIG.
FIG. 4A shows a first example, in which the hook member 7 is formed in a U shape using, for example, a resin material or a light metal material such as aluminum. Then, the intermediate portion A3 of the thermoplastic ear strap 4 can be attached to the hook member 7 by, for example, thermally welding the intermediate portion A3 to a portion of the side surface 7a of the hook member 7 .
In this state, the U-shaped bent portion 7b of the hook member 7 is engaged with the base portion of the ear strap 4 connected to the upper corner portion A1 of the mask body 2, whereby the second hook shown in FIG. A mask 1 having the same functions as the embodiment can be obtained.

FIG. 4B shows a second example of the hook member 7, which is also formed using a resin material or a light metal material such as aluminum. The hook member 7 is provided with a groove 7d through which the ear strap 4 is passed along the axis. A fixing screw 7e for fixing to 7 is attached.
A U-shaped bent portion 7b is formed in the hook member 7, and the bent portion 7b is engaged with the root portion of the ear strap 4 connected to the upper corner A1 of the mask body 2. Thus, the mask 1 having the same functions as those of the second embodiment shown in FIG. 3 can be obtained.
The fixing screw 7e may be fixed by thermal welding using a punch or the like.

FIG. 4C shows a third example of the hook member 7. As shown in FIG. This hook member 7 is different from the hook member 7 shown in FIG. will be provided.
Therefore, the same reference numerals are given to the parts having the same functions as the parts shown in FIG. 4B, and the description thereof will be omitted.
The first insertion portion 7g and the second insertion portion 7h of the ear strap 4 let the ear strap 4 attached to the through groove 7d go out of the hook member 7 through the first insertion portion 7g and the second insertion portion 7h. The ear strap 4 is passed through the portion 7h and returned into the groove 7d. As a result, a length adjusting function is provided for adjusting the effective length of the ear strap 4. - 特許庁

FIG. 5 is a side view showing the mask of the third embodiment in a worn state.
The mask 1 of the third embodiment differs from the mask 1 of the second embodiment shown in FIG.
That is, in the mask 1 of the third embodiment, one end and the other end of the ear strap 4 are heat-welded or super-welded at the upper corner A1 and the lower corner A2 on the front side of the mask body 2, respectively. Attached by sonic welding.
The configuration other than the attachment state of the ear straps 4 to the mask body 2 is the same as that of the mask 1 of the second embodiment shown in FIG. , and the description thereof is omitted.

According to the mask 1 of the third embodiment, the lifting members 6 by the ear straps 4 extending from the hook member 7 to the lower corner A2 are arranged along the outer sides of the left and right ends of the mask body 2. can be done. According to this, the left and right side portions of the mask body 2 are brought into close contact with the face side by the pull-up members 6 formed by the elastic ear straps 4 . As a result, when the mask 1 is worn, the central portions of both sides of the mask body 2 can be prevented from bulging outward, making it difficult to create a gap between the mask body 2 and the face.

FIG. 6 is a front view showing the essential parts of the mask of the fourth embodiment, and FIG. 7 is a side view showing the mask in a worn state.
The mask 1 of the fourth embodiment is an example of a cloth mask in which the mask main body 2 is three-dimensionally sewn according to the size of the face of a general wearer.
A mask body 2 covering the nose, mouth, chin, etc. of the wearer's face and a pair of ear straps 4 for locking the mask body 2 to the left and right ears of the wearer are provided.

In the mask 1 of the fourth embodiment, an elastic stretchable material is sewn along the upper edge of the mask body 2 as the upper hem cloth 8 . Extending to both sides of the mask body 2 at the corners A1, the ends of the upper hem cloth 8 are sewn in loops at the upper corners A1 to form the ear straps 4. As shown in FIG.
That is, in this embodiment, one end and the other end of the ear strap 4 are connected in a loop shape at the upper corner A1.

Also, in this mask 1, an elastic stretchable material is sewn along the lower edge of the mask body 2 as a lower edging cloth 9. It connects between the lower corners A2.
Further, on the left and right sides of the mask body 2, belt-shaped elastic bodies are sewn to the mask fabric so as to connect the upper corner A1 and the lower corner A2. It functions as a lifting member 6 that lifts the lower corner A2 toward the upper corner A1 of the mask body. The belt-shaped elastic body that functions as the pull-up member 6 is desirably stretchable such as plain weave rubber using elastic cords for the warp. It is desirable that the mask body 2 be configured to assist the expansion and contraction of the mask body 2 when opened and closed.

The mask 1 of the fourth embodiment is worn by hooking the ear straps 4 connected to the left and right upper corners A1 of the mask body 2 in a loop shape to the ears.
When the mask 1 is worn, the lifting member 6 pulls the lower corner A2 of the mask body 2 upward toward the upper corner A1.

Therefore, according to the mask 1 of the fourth embodiment, when the wearer lowers the lower jaw, the lower part of the mask body 2 wraps around the top h2 of the lower jaw, and the lower part of the mask body 2 is sewn. The extension of the lower edging cloth 9 and the pulling member 6 together with the cloth of the lower side drapes smoothly along the movement of the mandible.
On the other hand, when the wearer raises the lower jaw, the pulling action of the lifting member 6 and the lower hem cloth 9 causes the lower part of the mask body 2 to rise while wrapping around the top h2 of the lower jaw.
Therefore, the lower part of the mask body 2 always follows the movement of the lower jaw, thereby solving the problem that the mask body 2 is displaced from the mounting position.

In addition, in the mask 1 of the fourth embodiment, an example of using stretchable belt-like cloth as the lifting member 6 is shown, but it is also possible to use cloth made of a flexible non-stretchable material.
In this case, the lower part of the mask body 2 along with the sewn fabric of the mask body 2 is naturally lowered along with the movement of the mandible due to the extension of the lower hem cloth 9 .
In addition, between the upper corner A1 and the lower corner A2 of the mask body, a certain distance is maintained by a fabric made of a flexible non-stretchable material, and when the wearer raises the lower jaw, , the lower part of the mask main body 2 rises while wrapping around the top h2 of the lower jaw together with the lower edging cloth 9 and the sewn fabric of the mask main body 2 .
As a result, the lower part of the mask body 2 follows the movement of the mandible, and the problem of the mask body 2 slipping off can be solved.

As described above, when a fabric made of a flexible non-stretchable material is used as the pull-up member 6, as shown in FIG. It is desirable to use the retractor 10 to act to bring the lower corner A2 of the mask body 2 into close contact with the face.

FIG. 8 is a rear view of the essential parts of the mask of the fifth embodiment, viewed from the face mounting side, and FIG. 9 is a side view of the mask being worn.
