Description

The present invention relates to a mask that does not shift even when worn on a face and used.

It has been proposed that the mask to be worn on the face is hard to slip, and the outline is as follows.
As shown in Patent Document 1, strings attached to the upper and lower ends of the side edges of the mask are provided on both sides, and one string is hung on the back of the head between the middle and upper ends and on the neck between the middle and lower ends. Hooking, the middle part of the string was hooked on the hooking member that hooks the string on the opposite side of the mask. The other string was also hung on the back of the head, hung on the neck, and hung on the hooking member. The two strings were crossed at the back of the head and the neck.
In this proposal, it is not easy to adjust the balance between the length and tensile strength of the upper and lower ends of the string hanging on the back of the head and neck, and there is a problem that the mask will shift if used in a state where the adjustment is insufficient. rice field.

JP 2016-49155

This had the following drawbacks.
In the conventional invention of Patent Document 1, a string for attaching the mask to the face is divided into an upper end side and a lower end side from the middle part of the string and hung on the back of the head and the neck to fix the mask. In the middle part of the string, the string was hooked on the slidable hooking member, but the balance between the length and tensile force of the upper end side and the lower end side of one string should be automatically adjusted optimally. It was not possible to do so, and the balance was judged based on the feeling of hooking the string, and the string had to be hooked, so it was not easy to adjust the balance of the string. If the tensile force on the upper end side of the string was weak, the string hung on the back of the head was likely to slip, causing the mask to slip.
In the configuration of the invention of Patent Document 1, the upper end side and the lower end side of one string are hooked and supported by the hooking member in the middle portion, and at the same time, the hooking member on the opposite side is hooked near the hooking member. Because the straps are attached and the tensile forces on both sides of the hooking member are concentrated at one point, the upper end of the mask pulls the left and right hooking members or the vicinity of the hooking member. Even if the nose piece is provided at the upper end of the mask and bent to eliminate the gap between the upper part of the nose and the mask and prevent the glasses from fogging, when the tensile force of the string hooked on the hooking member becomes stronger, the bent part of the nose piece Was stretched to create a gap, which reduced the degree of adhesion, and the humidification of the mouth caused leakage and clouding of the glasses.

The present invention that solves the above problems has the following configurations.
The "base under the nose" referred to in the present application means a concave portion at the boundary between the nose and the upper lip. The "base of the ear above the ear" as used in the present application means a recess in the boundary between the ear and the head above the ear. The "inside of the mask body" as used in the present application means the side of the mask body in contact with the face. The "outside of the mask body" as used in the present application means the side of the mask body that does not come into contact with the face. The "upper side end" as used in the present application means the upper side end and its surroundings (the upper side end of the mask body and its surroundings).

The slip prevention mask according to the first invention is a mask provided with attachments on the left and right side edge portions of the mask body so that the mask body can be attached to the face, and the inside of the mask body is under the nose. It has a fixing string that passes through the side and holes or rings at the left and right upper side ends of the mask body, respectively, and the fixing string is inserted into the left and right holes or rings, and both ends of the fixing string are fixed. It is characterized by having a stopper to stop the string.
In the invention having the above configuration, the wearing tool is hung on the left and right ears to wear the mask body on the face. The fixing string passes through the base under the nose inside the mask body and is inserted into the left and right holes or rings. The fixing string that has passed through the hole or the ring passes through the bases of the ears above the left and right ears, and is fixed and fixed at both ends with a stopper and attached to the head. At the stop, tie both ends of the fixing string to stop. Further, the "stop portion" of the present application also includes fixing the fixing string by using a mounting fixture. When an elastic material is used for the fixing string, the "stop portion" of the present application also includes stopping by using the expansion and contraction of the fixing string. The "holes" of the present application also include holes in the mesh sheet. The "ring portion" of the present application also includes one that creates an annular gap between the thread attached to the mask body and the mask body.
The fixing string of the first invention is attached to the head in a state of being hooked from the bottom to the top at the base under the nose and in a state of being hooked from the top to the bottom at the base of the ear above the ear, and further, the chin or neck is moved. However, since it is installed in a position where it hardly moves, it can be maintained in a state where it hardly moves. Therefore, even if the jaw moves greatly due to sneezing, yawning, coughing, conversation, etc., there is almost no effect on the displacement. In addition, the fixing string does not slip or slip even if there is sebum or sweat. The fixing string fixed to the head does not move easily even if you try to move it up and down by hand.
In the first invention, a fixing string that does not move when attached to the head is inserted through the left and right holes or the ring portion. Therefore, the hole or the ring is caught by the fixing string and cannot move downward. Even if the chin or neck is moved, the mask body can maintain its original position attached to the face.
Since the fixing string of the first invention is attached along the face inside the mask body, the degree of adhesion between the mask body and the face is not lowered. In addition, the dome shape of the mask body does not collapse or further swell, and the original swelling can be maintained, and even if the first invention is attached, there is no pressure.

The slip prevention mask according to the second invention is characterized in that, in the first invention, the mask body is formed with pleats capable of spreading in the vertical direction.
In the invention having the above configuration, in addition to the same action as the first invention, the mask body is pleated so that the lower part of the mask body can be easily moved.
The left and right holes or rings of the second invention are hooked on a fixing string that does not move when attached to the head, so that the upper part of the pleated mask body moves downward. I can't. In addition, the lower part of the mask body can be moved up and down according to the chin by pleating, and when the mouth is closed, the wearing tool attracts the lower part of the mask body and returns to the original position, maintaining the original position. It becomes possible. Further, since the pleating process of the mask body absorbs the lowering force of the mask body to some extent, the force of pulling the fixing string can be weakened, and even if the second invention is attached, the mask body does not feel uncomfortable.

The slip prevention mask according to the third invention is characterized in that, in the first or second invention, the fixing string is formed into a ring shape.
In the invention having the above configuration, in addition to the same operation as in the first or second invention, the fixing string of the third invention is ring-shaped and therefore does not come off from the hole or ring.

In the first or second invention, the slip prevention mask according to the fourth invention has a substantially U-shape in which the fixing string is divided into two and through holes extending in the length direction are provided in the vicinity of both ends. In order to connect the front frame of the rod, connecting portions are provided on the left and right respectively, and the front frame is inserted into the left and right holes or the ring portion. The "long penetrating hole" of the present application also includes a long wide penetrating opening hole having an opening.
In the invention having the above configuration, in addition to the same action as in the first or second invention, mucus does not soak into the front frame by passing the front frame of the rod through the base under the nose instead of the fixing string.
The front frame of the fourth invention passes through the base under the nose inside the mask body and is inserted into the left and right holes or rings. The fixing string connected to the front frame through the hole or the ring at the connecting portion passes through the base of the ear above the left and right ears, and both ends are fixed with the fastening portion.
The front frame and the fixing string of the fourth invention are attached and fixed to the position of the head which hardly moves even if the jaw or the neck is moved. Since the hole or ring of the fourth invention is hooked on the front frame which does not move when attached to the head, the hole or ring of the mask body cannot move downward. Therefore, even if the chin or neck is moved, the mask body can maintain the initial position of being attached to the face.
Since the front frame passing through the inside of the mask body of the fourth invention is smaller than the covering portion of the mask body and has a shape that follows the contour of the face, the degree of adhesion between the mask body and the face is not lowered. In addition, the dome-shaped bulge of the mask body can be maintained, and even if the fourth invention is attached, there is no pressure.

In the first or second invention, the slip prevention mask according to the fifth invention is a substantially U-shaped rod or a substantially U-shaped rod that passes under the nose or above the back of the nose inside or outside the mask body instead of the fixing string. A fixed frame made of a tube is provided, and ear hooks to be hung on the ears are provided at both ends of the fixed frame, and the fixed frame is inserted into the left and right holes or rings.
In the fifth invention having the above configuration, in addition to the same operation as the first or second invention, it becomes possible to easily guide the fixed frame to the mounting position of the head by holding both sides of the fixed frame.
The fixed frame passing through the inside of the mask body of the fifth invention passes through the base under the nose or the back of the nose inside the mask body, and is inserted into the left and right holes or rings. The fixed frame that has passed through the hole or ring is hung on the ear at the ear hook. Further, the fixed frame passing through the outside of the mask body of the fifth invention passes over the back of the nose on the outside of the mask body and is inserted into the left and right holes or the ring portion. The fixed frame that has passed through the hole or ring is hung on the ear at the ear hook.
The fixed frame of the fifth invention is attached to the position of the head which hardly moves even if the jaw or the neck is moved. Since the hole or ring of the fifth invention is hooked on a fixed frame that does not move downward when attached to the head, the hole or ring of the mask body cannot move downward. Therefore, even if the chin or neck is moved, the mask body can maintain the initial position of being attached to the face.
Since the fixed frame passing through the inside of the mask body of the fifth invention is smaller than the covering portion of the mask body and is a fixed frame having a shape along the contour of the face, the degree of adhesion between the mask body and the face is not lowered. The dome-shaped bulge of the mask body can be maintained. Further, since the fixed frame passing through the outside of the mask body of the fifth invention does not pass through the bulging position in the center of the mask body but passes near the upper end of the mask body, the dome shape of the mask body is not crushed. The original bulge can be maintained. Therefore, the degree of adhesion between the mask body and the face is not lowered. Even if the fifth invention is attached, there is no pressure.

In any one of the first, second, or third inventions, the slip prevention mask according to the sixth invention has a hole hooking portion or a ring hooking portion on the hooking tool for hooking on the tip of the nostril or the outer nostril, and has a fixing string. It is characterized in that the central portion is inserted through the hole hooking portion or the ring hooking portion.
In the invention having the above configuration, in addition to the same action as that of the first, second or third invention, the fixing string is provided on the tip of the nose or the outside of the nostril by providing a hook for hooking on the tip of the nose or the outer nostril at the center of the fixing string. It can be hooked on the nostril (fixed at the tip of the nostril or the position of the outer nostril), and the position where the central part of the fixing string passes can be on the upper side of the nose.

In the fifth aspect of the invention, the slip prevention mask according to the seventh invention is formed on the left and right sides of a fixed frame made of a substantially U-shaped rod or tube passing over the back of the nose on the outside of the mask body. It features a cushioning tool to prevent breath from leaking from the upper end of the mask body.
In the invention having the above configuration, in addition to the same operation as in the fifth invention, the cushioning tool attached to the fixed frame fixed to the head of the seventh invention is a mask body having a recess extending from the back of the nose to both cheeks. By pressing (pushing) on the face, it is possible to eliminate the gap between the upper end of the mask body and the face.
The present invention comprises the above configuration.

According to the first invention, the fixed string is used as the mask body even under adverse conditions such as sneezing, yawning, conversation, etc. By preventing the displacement, it became possible to continue to maintain the mounting position at the time of mounting. Further, in the first invention, since the fixing string and the attachment are separate strings and the attachment method is different, one string is divided into an upper end and a lower end as in the invention of Patent Document 1, and the lengths of the upper and lower strings are obtained. There is no need to balance the pod tensile force. Therefore, the first invention does not cause the problem of the mask body being displaced and the problem of feeling uncomfortable due to the difference in the tightening balance of the strings.
Since the hole or ring of the first invention is only hooked on the fixing string, it can move along the fixing string and does not pull the upper end of the mask body to the left or right, so that the upper end of the mask body Moisture leakage from the mouth due to tension does not occur.
As an application of the first invention, for example, in a workplace or a medical field where food is handled, when the first invention is attached and the mask body is not displaced, the mask body may be inadvertently touched to correct the displacement. It disappeared and the hygiene was improved. In addition, by using the first invention, if the mask body is not displaced, the discomfort due to the displacement is eliminated, and the chance of contact infection by touching the mask body is reduced, so that viruses and bacteria can spread through the hands. It has decreased. Furthermore, until now, in the case of wearing a mask and performing dirty manual work, if the mask is displaced during the work, it is necessary to correct the displacement of the mask after washing the hands or removing the gloves. By wearing the mask, the mask does not shift, so there is no need to correct the shift of the mask until the work is completed, and it is possible to concentrate on the work.

In the second invention, in addition to the effect of the first invention, since the mask body has a pleated structure that spreads in the vertical direction, the lower part of the mask body can be easily moved up and down according to the chin. It returns to the position of, and the mask body does not shift. In addition, the pleating process of the mask body absorbs the lowering force of the mask body to some extent, so the force of pulling the fixing string can be reduced, and even if you continue to wear it, you can continue working without reducing your concentration. Has become easier.

In the third invention, in addition to the effects of the first or second invention, the fixing string does not come off from the hole or ring of the mask body.

In the fourth invention, in addition to the effects of the first or second invention, the mucus secreted from the nasal glands, goblet cells, etc. does not soak into the anterior frame, so that the mucus adhering to the anterior frame can be easily wiped off after wiping. Was able to eliminate the discomfort of the wiped area even when it was reattached. In addition, when an elastic material was used for the front frame, it became easy to hold the vicinity of both ends of the front frame and guide it to a position where the base under the nose passes.

In the fifth invention, in addition to the effects of the first or second invention, it is easy to hold both sides of the fixed frame and guide it to a position under the nose or above the back of the nose, and the fixed frame can be attached and detached. Has become simpler.

In the sixth invention, in addition to the effect of any one of the first, second or third inventions, a hook is used to fix the mucus secreted from the nasal gland, goblet cells, etc. on the upper side of the nose above the position where the mucus flows. Since it can pass through the string, it is possible to prevent mucus from staying on the fixed string.

In the seventh invention, in addition to the effect of the fifth invention, since there is no gap between the upper end of the mask body and the face, no breath comes out from the upper end of the mask body, and the eyes (contact lens wearing). (Including) is no longer directly exposed to breath or the glasses are no longer fogged. Even if a commercially available mask has a breath leakage countermeasure (nose piece, etc.) at the upper end of the mask body, if the mask body is displaced, the effect of the breath leakage countermeasure may be reduced. The fixed frame attached to the head and fixed prevents the mask body from slipping, and the cushion attached to the fixed frame does not create a gap at the upper end of the mask body.

The explanatory view and FIG. 10 seen from the bottom to the top when the guide portion is provided on the shift prevention mask according to the above are the cases where the guide portion (modification example) is provided on the shift prevention mask according to the first embodiment of the present invention. Explanatory view seen from the bottom to the top, FIG. 11 is a view of the side of the slip prevention mask (a modified example of the mask body) according to the first embodiment of the present invention in contact with the face, and FIG. 12 is an embodiment of the present invention. It is a figure which looked at the side which came in contact with a face of the displacement prevention mask (a modified example of a wearing tool) which concerns on form 1.

As shown in FIG. 1, the slip prevention mask 100 according to the first embodiment of the present invention has ears on the left and right side edge portions 66 of the mask body 1a so that the mask body 1a and the mask body 1a can be attached to the face. In the mask 90a provided with the attachment tool 2a that can be hung, the fixing string 3a that passes near the base under the nose inside the mask body 1a and the holes 80 that are the holes 80 in the left and right upper side end portions 65 of the mask body 1a. 8a are provided respectively, the fixing string 3a is inserted into the left and right holes 8a, and both ends of the fixing string 3a are fixed and fixed behind the head (fixed and fixed by a fixing portion 84 described later). By passing the fixing string 3a through the hole 8a, the hole 8a is caught in the fixing string 3a. The hole 8a, which is the hole 80, is a hole 8a that penetrates the front and back of the mask body 1a.

When the slip prevention mask 100 is attached to the face, as shown in FIG. 2, the attachment 2a is hung on the left and right ears to attach the mask body 1a to the face, and the fixing string 3a is centered inside the mask body 1a. Hook the area from the bottom to the base under the nose and pass over the base of the ears above the left and right ears. Behind the head, as shown in FIG. 3, both ends of the fixing string 3a are fixed and fixed by the fixing portions 84. In the fastening portion 84, both ends of the fixing string 3a are fastened with a knot 62b (a bow knot as an example of the knot), but it can also be fastened and fixed by using a mounting fixture 50 described later. The attachment order of the attachment 2a and the fixing string 3a is not particularly limited. The method of tying the knot 62b is not particularly limited as long as the fixing string 3a can be attached to the head.

The mask 90a of the slip prevention mask 100 is provided with a mask main body 1a and attachments 2a on the left and right side edge portions 66 of the mask main body 1a so that the mask main body 1a can be attached to the face. The mask body 1a is a mask used for the purpose of covering the mouth and nose, preventing the invasion of fine particles such as pollen and dust, preventing the invasion and scattering of viruses and bacteria, and preventing the scattering of saliva. The main body 1a is mainly made of a breathable member such as cloth, gauze, or non-woven fabric, and the material is not particularly limited. A known material used for the mask can be used. The breathable sheet of the mask body 1a may be a single sheet or a plurality of sheets (laminated structure), and one or more materials may be used. This is an example in which a polypropylene non-woven fabric sheet is used for the mask body 1a of the slip prevention mask 100. The attachment 2a is fixed (attached) to the mask body 1a by means such as welding (ultrasonic welding or the like), sewing, or stopping. Examples of the material of the fitting 2a include cotton, urethane fiber, nylon fiber, polyester fiber, polypropylene fiber, rubber and the like, but other known materials can be used, and these materials are not limited. .. As a special example of welding and fixing the mounting tool 2a to the mask body 1a, although not shown, a plurality of through holes (gap) are provided in a portion to be joined to the mask body 1a on the end side of the mounting tool 2a, and the mask body is provided. The joint portion of the fitting 2a is covered with a non-woven fabric made of the same material as 1a, and the through hole (gap) of the fitting 2a is filled with the non-woven fabric made of the same material and the mask body 1a by welding to connect and fix the fitting 2a. Further, although not shown, a cavity may be provided in each of the left and right side edge portions 66 of the mask body 1a in the vertical direction, and the attachment 2a may be attached in a ring shape by passing the attachment 2a through the cavity.

As shown in FIG. 2, the fixing string 3a of the slip prevention mask 100 is hooked from the bottom to the top at the base under the nose, and is hooked from the top to the bottom at the bases of the ears above the left and right ears. Attach and fix to the part. Furthermore, since the fixing string 3a can be fixed at the position of the head that hardly moves, it is a bad thing that the mask shifts, such as wearing it for a long time, being in a slippery state due to sebum and sweat, and moving the jaw greatly. Even under the conditions, it is attached to the head in a stable state and does not shift or come off. Since the fixing string 3a is attached along the face inside the mask body 1a, the dome shape of the mask body 1a is not crushed or further bulged. At the portion where the fixing string 3a comes into contact with the outside of the mask body 1a after the hole 8a is inserted, the mask body 1a is lightly sandwiched between the fixing string 3a and the face. It is possible to increase the airtightness of the upper side end portion 65 of the mask body 1a without lowering.

In the slip prevention mask 100, the fixing string 3a attached and fixed to the head is inserted into the hole 8a which is the hole 80, so that the hole 8a is caught in the fixing string 3a, and the fitting 2a is a mask. Since the main body 1a is attracted to the face, the mask main body 1a having the hole 80 cannot move in the vertical direction. Therefore, the mask body 1a can maintain the initial position without being displaced.

The fixing string 3a of the slip prevention mask 100 is preferably a string having a small elongation, and even if the hole 8a which is the hole 80 of the mask body 1a is pulled downward, if the elongation of the fixing string 3a is small, the hole of the mask body 1a The portion 80 cannot move downward. Specific examples of the material of the fixing string 3a include Japanese paper, cotton, linen, silk, lyocell fiber, rayon fiber, cupra fiber, polynosic fiber, acetate fiber, triacetate fiber, promix fiber, nylon fiber, and vinylon fiber. , Polyvinyl chloride fiber, polyester fiber, acrylic fiber, polyethylene fiber, polypropylene fiber and the like, but these materials are not limited. Further, the fixing string 3a may use one kind or two or more kinds of materials. The rubber or polyurethane fiber may be used as a covering material for the fixing string 3a in order to reinforce the knotting force. For the fixing string 3a of the slip prevention mask 100, a cotton flat string that is easy to tie and unravel is used as an example, but a known string having a small elongation can be used. As an example of the method of attaching the fixing string 3a to the head with a margin, lightly tie both ends of the fixing string 3a behind the head first, and slightly tie both sides of the fixing string 3a near the knot 62b on the head ring side. After pulling, by squeezing the knot 62b again, it can be stopped and fixed with a margin on the head ring side of the fixing string 3a, which can press the place passing through the nose and ears or bite into the skin. Prevent slack.

FIG. 4 is a modification of the hole 80 of the slip prevention mask 100, in which the inside of the mask body 1a is drawn centering on the upper side end portion 65 of the mask body 1a. Further, the left hole 80 paired with the right hole 80 is omitted because it is symmetrical with the right hole 80, and only the right hole 80 will be described. Further, FIG. 4 is an explanatory view of the hole 80, and the fitting 2a is omitted.

In the example shown in FIG. 4A, the deformation of the hole 80 provided with two holes 8a that penetrate the mask body 1a in the front and rear through the mask body 1a through which the fixing string 3a can be passed through the upper side end 65 of the mask body 1a. This is an example. A plurality of holes 8a may be arranged in the vertical direction or the diagonal vertical direction, and the number of holes 8a may be one or two or more. By inserting the fixing string 3a into one hole 8a from the inside of the mask body 1a, the hole 8a is in a state of being caught by the fixing string 3a, and the mask body 1a does not come off. When there are other holes 8a through which the fixing string 3a does not pass, they can be used for adjusting the mounting position of the mask body 1a in the vertical direction, and the number of holes 8a is not limited. The hole 80 on the left side is the same as that on the right side. In the example shown in FIG. 4B, four holes 8a are provided in the front and rear through the mask body 1a through which the fixing string 3a can be passed, at a position close to the edge side of the upper side end portion 65 of the mask body 1a.

In the slip prevention mask 200, by passing the fixing string 3a through the hole 8a which is the hole 80, the upper part of the mask body 1d does not move up and down because the hole 8a is caught by the fixing string 3a, and the lower part of the mask body 1d is Since it is pleated so that it spreads in the vertical direction, it can be moved up and down according to the jaw. Of course, when the chin returns to the upper position, the lower part of the mask body 1d is pulled by the fitting 2a and returns to the original position at the time of wearing, and the mask body 1d does not shift. The fixing string 3a is preferably a string having a small elongation, but the lower part of the mask body 1d can absorb the lowering force to some extent by pleating and weaken the pulling force of the fixing string 3a, so that a material such as rubber or polyurethane fiber can be used. A string having an elastic force made of the above can also be used. In that case, the stop portion 84 may be finely adjusted by using the mounting fixture 50. The mask body 1d of the slip prevention mask 200 may increase the number of pleats in order to further enhance the effect of absorbing the lowering force due to the pleated structure. Also, the folding dimension of the pleated folds may be slightly longer. Furthermore, when the mask body 1d is attached to the face, the mask body 1d may not be fully spread up and down, and may be attached with a margin. If a non-woven fabric that does not have directional strength or elongation and does not fray is used for the mask body 1d of the slip prevention mask 200, the hole size of the holes 8a does not increase even if it is used continuously, and pleating is easy. So good. This is an example in which a polypropylene non-woven fabric sheet is used for the mask body 1d of the slip prevention mask 200. Even if a known pleated mask is used for the mask 90d of the slip prevention mask 200, it is known by providing a hole 80 or a ring portion 82 at the left and right upper side end portions 65 of the mask body 1d and using a fixing string 3a. The pleated mask of the above is not displaced, and the displacement prevention mask 200 is obtained.

In the slip prevention mask 200, by passing the fixing string 3a through the hole 8a which is the hole 80, the upper part of the mask body 1d does not move up and down because the hole 8a is caught by the fixing string 3a, and the lower part of the mask body 1d is Since it is pleated so that it spreads in the vertical direction, it can be moved up and down according to the jaw. Of course, when the chin returns to the upper position, the lower part of the mask body 1d is pulled by the fitting 2a and returns to the original position at the time of wearing, and the mask body 1d does not shift. The fixing string 3a is preferably a string having a small elongation, but the lower part of the mask body 1d can absorb the lowering force to some extent by pleating and weaken the pulling force of the fixing string 3a, so that a material such as rubber or polyurethane fiber can be used. A string having an elastic force made of the above can also be used. In that case, the stop portion 84 may be finely adjusted by using the mounting fixture 50. The mask body 1d of the slip prevention mask 200 may increase the number of pleats in order to further enhance the effect of absorbing the lowering force due to the pleated structure. Also, the folding dimension of the pleated folds may be slightly longer. Furthermore, when the mask body 1d is attached to the face, the mask body 1d may not be fully spread up and down, and may be attached with a margin. If a non-woven fabric that does not have directional strength or elongation and does not fray is used for the mask body 1d of the slip prevention mask 200, the hole size of the holes 8a does not increase even if it is used continuously, and pleating is easy. So good. This is an example in which a polypropylene non-woven fabric sheet is used for the mask body 1d of the slip prevention mask 200. Even if a known pleated mask is used for the mask 90d of the slip prevention mask 200, it is known by providing a hole 80 or a ring portion 82 at the left and right upper side end portions 65 of the mask body 1d and using a fixing string 3a.
