Description

The present invention relates to a hygiene mask that does not cause pain even when the hygiene mask is worn for a long period of time, does not give anxiety in communication due to the inability to see the face, and enables eating while wearing the mask.

Due to the global pandemic of the new coronavirus infection, people are required to wear a hygiene mask at all times, not only when they are out of the office where there is a high possibility of interpersonal contact and infection, but also at home. It is becoming established as a cough etiquette.
Considering the barrier property against viruses and bacteria, it is easy to think that a hygiene mask with a higher degree of sealing is desirable, but a mask with a higher degree of sealing tends to cause pain to the wearer who is stuffy and is suitable for long-term use on a daily basis. Inappropriate. If you feel pain and remove the hygiene mask, you cannot prevent the infection.

Considering that the corona sickness will continue in the future, it is necessary to reduce the overall risk of infection, as well as to ensure the quality of life and economic activities, and to reduce the stress and secondary damage caused by hygiene masks. For that purpose, it is necessary to use different hygiene masks according to the situation.

There are face shields and mouth shields that use transparent plastic as a partition forming member in order to make facial expressions visible and prevent the spread of saliva and droplets.

However, although the face is clearly visible in many of these, breathed breath and saliva tend to adhere to the surface of the shield member and become cloudy, making it difficult to see, and it is necessary to wipe them off every tens of minutes. In addition, not only is there a feeling of oppression when worn and a feeling of intimidation to others, but there is no way to prevent the diffusion of droplets from the space between the face and mouth to the outside.

On the other hand, the sanitary mask disclosed in Patent Document 1 has light transmission and bacterial barrier properties, and is intended to make facial expressions visible when the sanitary mask is worn and to reduce an unpleasant impression due to the sanitary mask. ..

The mask body of this sanitary mask has a horizontally long rectangular shape. Ear hook strap fixing parts are provided on both the left and right sides of the mask body. The central portion of the mask body except for both ends in the lateral direction is a facial covering portion that covers the mouth of the wearer's face. In the face covering portion, a substrate layer having regularly formed through holes and a nanofiber layer having a fiber diameter of 350 nm or less and a basis weight of 0.50 g / m or less are integrated as a laminated sheet, and parallel light rays of the face covering portion are formed. The transmittance is formed to be 10% or more.

Patent Document 2 states that the wearer's face is transparent and transparent, prevents the inhalation of foreign substances floating in the air such as pollen, and sufficiently discharges droplets generated from the respiratory organs such as the nose and mouth. A sanitary mask that can be blocked is technically disclosed. The transparent woven fabric is composed of synthetic fiber filaments and is treated with a water repellent treatment. The peripheral edges of the transparent woven fabric are heat-fused or surrounded by a resin sheet that is curved into an eggplant-shaped or U-shaped shape.

Patent Document 3 discloses a hygiene mask in which the nose portion is exposed with the first priority being relief from suffocation. The thin material that makes the movement of the wearer's mouth visible from the outside and the structure that maintains the transparency make it possible to speak from the movement of the wearer's mouth even when a large number of people are working. It is possible to determine who is who and what kind of content they are talking about.

The main body of this hygiene mask has a notch formed in the center of the upper end of the under-nose receiving part, and is formed so that the main body protects the circumference of the wearer's nose to protect the wearer's chin. By extending the main body downward, the wearer can protect it from radiant heat and splashed oil during work such as cooking.

Japanese Patent No. 5961738 Japanese Unexamined Patent Publication No. 2013-66643 Utility model registration No. 3210083

In Patent Document 1, the sanitary mask disclosed has a face covering portion that covers the mouth of the wearer's face at the central portion excluding both ends in the lateral direction of the mask body having a horizontally long rectangular shape. Therefore, in order to open the front of the mouth for eating, the ear hooks provided on the left and right sides of the mask body must be removed from both ears. Therefore, it is inevitable to take almost the same behavior as the above-mentioned behavior, and it is not possible to eat while wearing a mask.

Like the hygiene mask disclosed in Patent Document 1, the hygiene mask disclosed in Patent Document 2 is for eating, so that the front of the mouth is opened to cover the respiratory organs such as the wearer's nose and mouth. The ear hooks that are formed integrally with the mask body must be removed from both ears, and it is not possible to eat while wearing the mask.

Similar to Patent Document 1 and Patent Document 2, the hygiene mask disclosed in Patent Document 3 also has both ends of the rubber cord fixed to the upper part and the lower part of the back surface of the main body portion connected to the mouthpiece portion covering the wearer's mouth. Since the wearing part is formed by doing so, in order to open the front of the mouth for eating, the main body part connected to the mouthpiece and the ear hook string must be removed from both ears, and a mask is worn. You can't eat as it is.

An embodiment in which the main body portion is extended downward is disclosed, but this extended portion is for a cook or the like, and is located below the mouthpiece portion of the main body portion, and is cooked by the wearer. This is to protect the chin and neck from radiant heat and splashed oil during work such as inside. Since the downwardly extending part closes the mouth, it is difficult to eat, and after all, it is not possible to eat with this mask on.

In this way, all of these patent documents describe the problems when using hygiene masks for a long time in the field where communication is important, especially the meal that facilitates communication, which is a problem due to virus infection and the like. No mention is made of the relationship with hygiene masks or how hygiene mask users handle hygiene masks during meals.

It takes time to remove both ear hooks of the hygiene mask from both ears. This is because even if you can remove it from your right ear with one hand, it is difficult to remove it from your left ear in the opposite direction with your right hand. Conversely, even if you can remove it from your left ear with your left hand, it is difficult to remove it from your right ear with your left hand. To remove it with both hands, you have to stop the work with your right or left hand, and it takes time to stop the work, which requires at least several tens of seconds to several minutes. However, in the past, we have not been aware of the problems that exist in the relationship between conversation during meals and wearing masks. The general practice is to remove the mask during meals and place it on a table, or store it in a pocket or special case, and then put on the mask again after meals.

Therefore, in order to prevent the scattering of saliva and the like due to conversation during meals, it is required to strictly prohibit conversation during meals and concentrate on eating silently during meals. No matter how strict the rules are, no effect can be expected with the infection control method that ignores and hinders smooth communication such as conversation while eating, which strictly prohibits conversation during meals.

The present invention solves the problem of wearing a sanitary mask for a long time while emphasizing the aesthetic appearance when the mask is worn because it has light transmission that was not recognized as a problem in the conventional sanitary mask described above. Moreover, the purpose is to provide a hygienic mask that enables eating while wearing it.

In order to be able to instantly deal with the spread of droplets due to sudden coughing or sneezing during meals while taking advantage of the smooth communication effect of conversation while eating, the following two actions must be dealt with. It doesn't become.

That is, in order to put food and drink in the mouth during meals, the hygiene mask that covers the mouth surface "should not exist", but it prevents the spread of droplets due to sudden coughing or sneezing during meals. The purpose is to provide a sanitary mask that solves the antinomy contradictory problem of "must exist".

In order to achieve this purpose, the temporal issue that the hygiene mask "exists" in front of the mouth and "does not exist" in front of the mouth during meals is changed to the spatial relationship between the covering body of the hygiene mask and the ear hook string. I focused on it and solved it. That is, if an ear strap fixing portion is provided at the corner above the center of the covering main body, the lower end side of the covering main body is squeezed by hand and lifted outward in a half-folded state, the upper part of the covering main body becomes the face. While it is curved along the upper end, the lower end of the covering main body connected to the upper end is curved along the face in a direction opposite to the bending direction of the upper end of the covering main body.

In such a state, even if the hand is released, the lower end of the covering main body remains independent, and spatial separation that "the covering main body does not exist in front of the mouth" becomes possible, resulting in infection. For prevention, "I want a sanitary mask to exist", but for meals, I got the idea that I can solve the time problem of "I don't want a sanitary mask to exist" and solved the problem. ..

The hygiene mask according to the present invention is a covering main body in which at least two horizontally elongated fabrics that are flexible and cover the face are overlapped so as to be separated from each other, and the upper edge portion and the lower edge portion of each are closely fixed. It is provided with a portion and an ear strap fixing portion provided at the left and right corners above the vertical center portion of the covering main body portion.

The binaural strap fixing portions of the sanitary mask according to the present invention are provided at both ends above the vertical center portion of the covering main body portion at an angle of about 40 to 50 degrees, respectively.

In the central portion of the covering main body of the sanitary mask according to the present invention in the vertical direction, a folded portion extending in the lateral direction is provided over the left and right ends.

The covering main body of the sanitary mask according to the present invention is made of an organdy fabric in which polyester multifilament warps and wefts are plain weave.

The inner upper end of the covering main body of the sanitary mask according to the present invention is covered with a flexible narrow gauze band.

That is, the ear hook string provided on the sanitary mask according to the present invention is attached to the ear hook string fixing portion provided at an inclination of about 40 to 50 degrees at each of the left and right ends above the vertical center portion of the covering main body portion. Since it is fixed, when the lower end side of the covering main body of the sanitary mask is turned up and outward, the lower end side bends along the face in the direction opposite to the bending direction of the upper end surface of the covering main body. Even if you let go of your hand, you can maintain an independent state, and while wearing a sanitary mask, you can separate the covering body from "existence" and "non-existence" in front of your mouth.

Further, in the covering main body of the sanitary mask according to the present invention, the front cloth and the back cloth of the organdy fabric in which the warp and weft of the polyester multifilament are plain-woven are slightly offset and overlapped with each other. Moire fringes appear on the surface.

The hygiene mask of the present invention has good light transmission and breathability, has excellent visibility of the wearer's facial expression, has good breathability, and is softly along the face so that the light cloth of the covering body covers the face from above. Since it just hangs down, it does not cause suffocation, and it does not cause any pain even if it is used all day long. Moreover, unlike face shields and festival masks, it can be used without the troublesome operation of constantly cleaning the surface that is clouded with breath or saliva.

In addition, the hygiene mask according to the present invention can be turned up in an instant with one hand to stand on its own, so there is no need to remove the hygiene mask from the ear during meals, and only when putting food in the mouth with one hand. It is possible to instantly turn up the covering main body to make it self-supporting, and to instantly lower the lower edge of the covering main body from chewing to swallowing. By such a usage method, it is possible to catch the droplets scattered during chewing while smoothly communicating during meals. Furthermore, if you are about to cough or sneeze, you can not only prevent the spread immediately, but also prevent the spread of droplets associated with conversation during chewing.

Hereinafter, description will be made with reference to the drawings based on the preferred embodiment of the present invention.
The sanitary mask 1 according to an embodiment of the present invention has the structure shown in the front view of FIG. 1 and the rear view of FIG.

As shown in FIGS. 1 and 2, the covering main body consists of two organdy fabrics, which are plain weaves of polyester multifilament having flexibility, light transmission, and breathability, with warp 20 denier and weft yarn 40 denier, on the front and back. Used as a cloth, a horizontally long front cloth and a horizontally long back cloth made of organdy fabric with almost the same shape and the same characteristics are overlapped so that the central part can be separated, and the upper edge and the lower side of each are overlapped. Closely fix the edge part, and cover the main body part outer cloth 2. The backing cloth 3 of the covering main body is used.

In the following description using FIGS. 1 and 2, close contact fixing by sewing is shown, but this is because a plurality of fabrics forming the covering main body front cloth 2 and the covering main body back cloth 3 are used. Since the purpose is to firmly fix the upper edge and the lower edge of each so that they do not shift back and forth, left and right, and up and down, in addition to sewing, the fabric made of polyester fabric or non-woven fabric is melted and blown. Other means and methods such as bonding with an ultrasonic fusing cutter that cuts the molten surface without generating burrs, adhesion using an adhesive, and fusion by heat may be used.

Therefore, the left and right sides of the sanitary mask 1 are covered by hand because the central end portion 25 is formed by superimposing the covering main body portion front cloth 2 and the covering main body portion back cloth 3 so that the central portion can be separated from each other. When the central portion of the main body portion front cloth 2 and the covering main body portion back cloth 3 is squeezed and pulled in opposite directions, a gap is formed between the two.

In this way, the front cloth 2 of the covering main body and the back cloth 3 of the covering main body are overlapped so that the central part can be separated from each other, so that the water droplets of saliva coming out of the mouth form the warp and weft of the polyester multifilament. Even if it passes through the lattice of the covering main body lining cloth 3 formed of plain weave, the warp and weft of the polyester multifilament also collide with the lattice of the covering main body lining cloth 2 formed of plain weave in the traveling direction. However, it is supplemented and does not scatter beyond that.

Further, light interferes with each other in the lattices of the covering main body front cloth 2 and the covering main body back cloth 3, and moire fringes are displayed on the surface of the covering main body front cloth 2. The moire fringes vary in the degree of light scattering depending on the shape of the wearer's face, and none of them are the same, giving a unique aesthetic impression to the person facing the wearer of this sanitary mask.

In order to cover the face of the sanitary mask user with the covering main body front cloth 2 and the covering main body back cloth 3 so that they can be hung on both ears of the user, a rubber ring-shaped ear hook string 41 is attached. The ear hook portion 4 is provided, and the mounting position of the ear hook portion 4 is devised in order to enable a long time of the sanitary mask.

In the conventional sanitary mask, the ear hook is hung on the left and right sides of the covering body between the vertical upper and lower corner ends of the covering body, and the ear hook is in the direction of attracting the covering body to the face. An ear hook is provided so that a pulling force does not create a gap between the hygiene mask and the face, and the covering body always covers the front of the mouth. Unless the mask is removed, the covering body will continue to exist in front of the mouth, and in order to prevent gaps, the hygiene mask will constantly press on the face, which constantly causes pain to the hygiene mask user. continue.

On the other hand, in the sanitary mask 1 according to the embodiment of the present invention, the covering main body hangs down from the top of the face so as not to cause pain to the sanitary mask user even if the sanitary mask is worn for a long time. Ear hooks are provided at the left and right upper corners of the main body of the mask so that the face can be covered so that it can be lightly touched.

That is, since the outer material 2 of the covering main body and the left and right end portions of the backing cloth 3 of the covering main body are locked, the left and right corners above the central portion in the vertical direction are inclined by about 40 to 50 degrees, preferably 45 degrees, respectively. Ear hook string fixing portions 22 are provided on the left and right. Therefore, rather than attracting the covering body to the face, it is slanted in order to hang it.

In the ear hook string fixing portion 22, the corners of the overlapped covering main body outer material 2 and the covering main body backing cloth 3 are folded back so as to be hollow inward, and the seams 9 are sewn. A ring-shaped ear strap 41 is passed through the hollow portion of the ear strap fixing portion 22, and the upper side of the ear strap 41 is engaged with the upper fixing portion 42 located above the ear strap fixing portion 22. The lower side of the ear hook string 41 is stopped by the lower fixing portion 43 located below the ear hook strap fixing portion 22. The rubber cord used as the ear strap 41 is soft and soft to the touch, and uses antibacterial processed natural rubber with excellent elasticity (elongation rate 250%), strength, and durability that is often used for baby products and children's products. ing.

The covering main body front cloth 2 and the covering main body back cloth 3 of the sanitary mask 1 are overlapped with each other and folded inward at the upper end edge portion 21 to form the upper folded portion 6. A flexible narrow gauze band 7 is further superposed on the upper folded portion 6, and the position of the seam 9 is sewn. Therefore, the organdy fabric does not come into direct contact with the face surface and induce inflammation on the skin. It is the soft gauze that comes into contact with the skin of the face, and the lower part of the mask is open and has good breathability, so that the makeup does not come off when the mask is worn.

The soft gauze uses a non-woven gauze made from cotton, which has very little fiber shedding, so it is difficult to remove fluff and friction is small, so damage when rubbing against the skin can be suppressed. In addition, since it can quickly absorb and retain about 13 times its own weight of water, it can maintain a dry feel without being sticky even if it absorbs sweat.

Similarly, the front cloth 2 of the covering main body and the back cloth 3 of the covering main body are overlapped with each other so that the central portion can be separated from each other, folded inward at the lower end edge portion 23, sewn at the position of the seam 10, and folded downward. Part 8 is formed.

Since this sanitary mask 1 requires flexibility, light transmission, and breathability, an organdy fabric in which polyester multifilament warps and wefts are plain-woven is used. In selecting this organdy fabric, the results observed with a scanning electron microscope will be described.

FIG. 3 shows the result of observing the surface of one organdy cloth with a scanning electron microscope. The distance between the fibers of one organdy fabric was about 200 μm. Generally, it is considered that one drop of water is about 50 μl, so that the amount of splashed water droplets scattered by sneezing or coughing is also considered to be about the same. Therefore, when this organdy fabric is used for the main body of the covering, the facial expression and movement of the face and mouth can be seen transparently, but the scattering of water droplets due to saliva and sneezing is 200 μm vs. 50 μl, which prevents scattering. The effect is thought to be weakened.

FIG. 4 shows the results of observing the surface of the fabric with a scanning electron microscope when two organdy fabrics are stacked. The distance between the fibers when two orgy fabrics are stacked is about 50 μm to 100 μm. As mentioned above, it can be said that a splash of about 50 μl scattered by sneezing or coughing can be sufficiently caught. This is the result obtained by observing the surface of the front cloth with the scanning electron microscopes of FIGS. 10, 11 and 12 due to the refraction and mutual interference of the light when the light passes through the front cloth and the back cloth.

FIG. 5 shows the results of observing the surface of the fabric with a scanning electron microscope when three organdy fabrics are stacked. The distance between the fibers when three orgy fabrics are stacked is about 10 μm to 50 μm. It is possible to catch about 50 μl of splashes scattered by sneezing or coughing more than when two layers of augage fabric are stacked, but the flexibility, light transmission, and breathability are when two layers of augage fabric are stacked. Will be inferior to.

As described above, in the sanitary mask 1 of the embodiment of the present invention, if two or more organgie fabrics are used for the covering main body portion, moire fringes are clearly displayed on the surface of the covering main body portion, and the person wearing the sanitary mask. The moire stripe pattern appears to change slightly depending on the standing position, line of sight, and angle of the viewer, giving an aesthetic impression peculiar to the moire stripe and giving a sense of security.

Next, when the lower end side of the covering main body surface cloth 2 of the sanitary mask 1 is squeezed by hand and lifted upward along the face, the lower end side maintains an independent state even if the hand is released, and hygiene. While the ear hook 4 of the mask 1 is attached to the ear, the front cloth 2 and the back cloth 3 of the covering main body can be separated temporally and spatially from "existence" and "non-existence" in front of the mouth. The mechanism and how to use the sanitary mask 1 will be described with reference to FIGS. 6 to 9.

FIG. 6 is an explanatory view in which the ear hook portion 4 of the sanitary mask 1 is worn by hanging it on both ears. FIG. 7 shows a state in which the lower folded portion 8 of the sanitary mask 1 is picked up by hand and lifted upward while eating.

In such a state, the sanitary mask 1 resists the pulling force of the left and right ear hook rubber cords 41 and lifts the lower folded portion 8 upward by hand. At this time, the covering main body portion outer cloth 2 and the covering main body portion 3 are made of a flexible organdy fabric, and the rigidity of the upper folded portion 6 of the covering main body portion outer cloth 2 and the sewn gauze portion 7 are sewn. , The warp and weft that form the front cloth 2 and the back cloth 3, and the overlapping contact resistance due to the weft, etc. A folded portion extending laterally over the portion will be formed. That is, the lower portion connected to the upper side of the covering main body portion upper cloth 2 is curved and folded back along the facial contour in the direction opposite to the upper bending direction. Therefore, as shown in FIG. 8, the lower folded portion is folded back. The self-supporting state is maintained so that 8 is located on the upper side.

Therefore, even if the hand is released from the sanitary mask 1, the self-standing half-folded state is maintained as it is. In such a state, the front of the mouth surface is opened, so that it is possible to put food or drink 11 in the mouth and eat as shown in FIG. Then, during the period from mastication to swallowing, the droplets during mastication can be caught by lowering the lower edge portion of the covering main body portion to the lower side. Furthermore, if you are about to cough or sneeze, you can not only prevent the spread immediately, but also prevent the spread of droplets associated with conversation during chewing. Therefore, it is important in terms of function and design that the ear hook portion is provided diagonally from the center in the vertical direction to the upper side of the covering main body portion.

In the above-described embodiment, the covering main body front cloth 2 and the covering main body back cloth 3 are each flat cloth, and the folded portion at the central portion thereof extends laterally over the left and right ends. However, the underside of the sanitary mask 1 was squeezed, the backing cloth 3 of the covering main body was smoothly turned over to the front side, and the lower folded portion 8 of the backing cloth 3 of the covering main body was formed of the backing cloth 2 of the covering main body. In order to invert it so that it is located on the upper side, one or more creases are made in advance along the center line CC of the covering main body front cloth 2 and the covering main body back cloth 3, or a wavy shape like a pleated skirt cloth. If the folded part is formed by several methods such as ironing and pressing, not only the covering main body part can be easily inverted, but also an aesthetic impression different from the moire fringe can be given.

In still another embodiment, the folded portion is formed in a horizontally long groove shape or is projected in the opposite direction, and the folded portion in the shape of a string or a strip is formed by means or methods such as sewing, fusion, and adhesion. You may. In short, it may be formed so as to cause a slight difference in the rigidity between the folded portion and the fabric of the other covering main body portion.

The weight of the sanitary mask 1 of the present embodiment is about 2.9 g, which is about 0.5 g lighter than the weight of a general non-woven fabric sanitary mask of about 3.4 g, and the ear hook string 41 is moved upward and left and right. It is formed so that the covering body is hung from above by fixing it to the mask, and the lower left and right sides of the covering body are released, so you can not feel the stuffiness and blockage when wearing the mask, and it is comfortable enough to forget to put it on. Can be maintained.

With the conventional sanitary mask, even if it is forcibly worn, it is limited to a few hours, whereas with the sanitary mask 1 of the embodiment of the present invention, it is painful even if it is worn for 12 hours or more. It is suitable for long lectures and work because it does not feel.

After use, the sanitary mask 1 of the present embodiment can be reused in its original state after several hours by washing it by hand with lukewarm water or water and soap, drying it indoors after towel drying. Since it is made of a material and form with excellent durability, it can be used under the same conditions and conditions for more than a month without problems even if it is used and washed repeatedly every day.
