Description

[Technical Field]

[0001] The present invention is a groundbreaking invention of a mask that eliminates the drawbacks of known masks for the novel coronavirus, SARS, MERS, influenza, etc. The reasons for this are explained below. [Background technology]

[0002] Currently, the novel coronavirus is spreading, and the increasing rate of person-to-person infection is causing panic. Furthermore, since there is no effective medicine, the only countermeasures are washing your hands and wearing a mask. Summary of the Invention [Problem to be solved by the invention]

[0003] Disadvantages of known masks include: (1) The virus enters through the eyes. (2) Unable to converse. (3) My glasses are fogging up. (4) The size of the virus is 0.1 micrometers, so the virus can pass through both nonwoven and cloth masks. (5) Touching your face to remove the mask. (6) Lipstick and makeup get on the skin, which women dislike. (7) Since I cannot see the person's mouth, I cannot communicate by lip reading. (8) People who have the habit of touching their eyes or face with their hands can get the virus. (9) It is a waste of resources because it is discarded after one use, and the total cost is high when it is used for a long period of time. (10) My ears hurt if I wear them for a long time. (11) Putting on and taking off the earphones is a hassle. (12) Masks are irregular in shape, so they are ineffective unless they are stretched to fit the face and make contact, which is cumbersome. (13) For example, babies and small children dislike having their faces touched. There are some drawbacks, such as: Conventional masks are made of fabric or nonwoven fabric with a breathable structure that allows air to pass through, so they only prevent viruses and bacteria by up to 70%, but allow 30% of viruses and bacteria to pass through.In addition, viruses and bacteria can get into gaps in the mask, posing a risk of them entering through the nose or mouth. Furthermore, since viruses and bacteria cannot be removed once they have adhered to the mask, it is necessary to either discard the mask and use a new one, or to remove the viruses and bacteria by boiling or the like before reusing the mask, which is a cumbersome process. Furthermore, known masks do not cover the eyes, so if the new coronavirus or other viruses splash onto your eyes or if you touch your eyes with your hands, the eyes are connected to the nose, and the nose is connected to the throat, so the viruses can enter the throat and reach the lungs, potentially causing pneumonia and leading to death. Additionally, it is difficult to communicate while wearing known masks. However, when doctors talk to patients, they have to remove their masks, which has the disadvantage of allowing viruses and bacteria to enter the body. For these reasons, there is a need to invent a revolutionary mask that can replace the known masks and eliminate the drawbacks of the known masks. [Means for solving the problem]

[0004] In order to eliminate the above drawbacks, this invention is a super mask that can protect not only the mouth and nose but also the eyes, which were previously inaccessible, and is made of a non-breathable material that blocks 100% of bacterial droplets from the patient, and is designed so that speech from the mouth can be transmitted to the other person.The name of the invention, "Super Men (MEN)," means "men" (face), "M" (Mouth), "E" (Eye), and "N" (Nose), and represents an "excellent mask" that protects from viruses and bacteria. The masks claimed in the present invention include so-called face shields. [Effects of the Invention]

[0005] 1. Conventional masks are made of fabric for breathing purposes, so viruses can pass through and only prevent 70% of viruses and bacteria, whereas the mask of this invention is made of a plate, so it can block and protect 100% of viruses and bacteria. 2. In addition, while conventional masks muffle voices when worn, making it difficult to talk or communicate, the present invention has the great advantage of allowing completely clear conversation without muffling voices. For example, when a doctor speaks to a patient, he or she is forced to move the mask, which can lead to infection, but the present invention allows conversation while wearing the mask, which is safe and convenient. 3. When wearing glasses with a conventional mask, steam comes out from the top of the mask, which comes into contact with the cold air and fogs up the glasses. For example, nurses who wear glasses often leave their nostrils exposed when wearing a conventional mask, allowing viruses and bacteria to enter through the nostrils. With this invention, glasses do not fog up, allowing clear vision and preventing accidents. Furthermore, because books and signs can be clearly seen, wearing the mask while driving a car is a significant advantage in preventing accidents. 4. Furthermore, even when not wearing glasses, the present invention has a structure that allows the wearer's breath when talking or breathing to flow in and out downwards, so the transparent protective plate does not cloud the field of view and provides a good field of view. 5. Furthermore, while conventional masks could only be used once, the mask of the present invention does not come into direct contact with the mouth, nostrils, or eyes, so it does not get dirty and can be kept clean, allowing it to be used semi-permanently many times, and therefore has the effects of being low cost, convenient, and easy to use. 6. Furthermore, the product of the present invention is thin, lightweight, portable, low-cost, and does not take up much space when stored or transported. 7. Furthermore, the present invention has an inventive structure in which the product is flat when transported or stored, but is curved when in use to increase its strength, which has the effect of allowing the use of thin, light, and inexpensive materials. 8. Furthermore, the device surface can be sprayed with a disinfectant or sterilizing liquid such as "NAKAMAGIC Wash" developed by the inventor, which can easily kill any attached viruses and other bacteria, further improving the antibacterial effect. This is not possible with conventional masks. 9. Furthermore, while conventional masks have a breathability of 70-85%, the present invention has the advantage of having 100% breathability. 10. Furthermore, while known masks obscure the face of a person when worn, the present invention allows the face to be clearly seen even when worn, which is advantageous in terms of convenience for conversation and identification. 11. On the other hand, if the transparent plate of the present invention is made transparent only in the area around the eyes, it will be more effective at hiding the face than conventional masks. 12. Furthermore, while known masks do not allow symbols or letters to be written on them, the present invention allows writing and erasing on the transparent plate, which has the effect of improving the usefulness of the mask for purposes such as identification numbers and public relations. 13. It is easier to wear than conventional masks and goggles, and is lighter, less expensive, and less complicated. 14. Compared to conventional goggles, the present invention has the advantages of a wider field of view, being lighter, cheaper, and easier to handle. 15. When washing or drying your hands with a jet-powered hand wash or dryer, viruses and bacteria on your hands can get into your eyes, but wearing this invention can prevent this. 16. Since the present invention does not come into contact with the eyes, nose, or mouth, it can be reused by family and friends multiple times, which has the effect of reducing costs. 17. The twenty-fifth embodiment has the effect of enabling the present invention to be produced immediately at the scene of an emergency. 18. In the 24th and 25th embodiments, the device is small enough to fit in a pocket, making it easy to carry and store, and it can be used immediately whenever and wherever necessary. 19. The 26th embodiment of the present invention can be implemented very easily by utilizing an existing hat. 20. Conventional masks get lipstick and makeup on them, but the mask of this invention does not come into contact with the front of the face, such as lipstick or eyes, so women can wear it without worry. 21. Because it is thin, it can be carried in a thin place such as under clothes or under a bag, and because it can be rolled up, it can be stored in a narrow space in the corner. Therefore, if you are in a crowded place, you can suddenly take it out and use it to protect yourself from coronavirus and other diseases. 22. It can be cleaned multiple times and used multiple times, which makes it cheaper than conventional masks. 23. Anti-fray tape is wrapped around the end of the rubber band at right angles to its length, which helps prevent the rubber band from fraying. 24. Even if you have the habit of carelessly rubbing your eyes without realizing that your hands have bacteria or viruses on them, touching your eyes can still prevent bacteria and viruses from entering your eyes. 25. People with hearing impairments cannot communicate with conventional masks because they cannot see the mouth and cannot read lips, but with this mask, the mouth is transparent and can be seen, so even people with hearing impairments can communicate. 26. In the customer service industry, conventional masks do not convey a smile to the other person and are expressionless, which can be unpleasant. However, this invention conveys a smile to the other person, which has the effect of leaving a good impression on the customer and making them feel warmly welcomed. 27. The present invention has been proven effective in making many women's faces appear more beautiful than they actually are. This is because the transparent plate 4 of the present invention collects light and reflects it off the skin, hiding rough skin, and the transparent plate 4 of the present invention is curved horizontally, creating a lens effect that makes the face appear longer. This effect is not found in conventional masks. 28. In the present invention, breath fills the inside of the transparent plate 4, so even when the outside air temperature is low, the heat conduction coefficient is low between the transparent plate 4 and the air layer in front of the face, so you feel warm even outside in the cold winter or in an air-conditioned room. This effect is not found in conventional masks. 29. By placing an LED anywhere on the outside front of the cushion and a battery anywhere inside, the vehicle can travel in dark places at night, improving safety. By attaching reflective tape anywhere on the transparent plate, the vehicle can be seen by oncoming vehicles, ensuring personal safety. 30. The structure of the present invention comprises: (1) Compact when stored and carried (2) When in use, the structure is strengthened by bending. 31. Normally, the bottom end of the transparent plate would spread out when worn, but since the rubber band of the present invention is attached to the bottom end of the wide cushion, the bottom end of the transparent plate does not spread out. 32. This invention does not hang over the ears, so the ears do not hurt. 33. When wearing this invention, the air pressure in the space between the transparent plate and the face becomes higher than the air pressure of the outside air, preventing viruses, bacteria, etc. from entering from the outside. 34. When wearing this invention, the humidity and temperature in the space between the transparent plate and the face increase, so even if viruses or other microorganisms enter, they will be killed. 35. Since the device is fixed with staples, the Velcro (registered trademark) and rubber band will not come off when the device is attached or detached. 36. The ends of the rubber band are folded over and fixed, which helps prevent the rubber band from fraying. 37. A cushion is provided at the bottom of the transparent plate, and the box shape prevents outside air from entering the space between the transparent plate and the face. 38. The space between the transparent panel and your face must be at least 50% humidity and 22°C temperature, which will kill the coronavirus. 39. By folding the sides of the transparent plate or reinforcing them with other materials, the strength of the sides is increased, and the transparent plate will no longer deform due to wind, etc. 40. The mask of the present invention for infants and young children is made of a small transparent plate with a protective member covering the edges. (1) Even babies can breathe easily. (2) It only requires light contact, so even babies will not dislike it. (3) The transparent board means that even babies can see it without feeling uneasy. (4) There is no contact with the nose or mouth, so the child does not mind. (5) The mother can easily hear the baby's crying and other vocalizations and can respond immediately. (6) It is effective in providing complete protection from droplets from above, even when the baby is sleeping. 41. Rounding the corners of the transparent board can prevent injuries. 42. By attaching plasma or aluminum tape to part of the transparent plate, it reflects the heat emitted from body temperature, further increasing the temperature and pressure in the gap between the transparent plate 4 and the face, preventing the entry of bacteria and viruses. 43. By holding the transparent plate with multiple rubber bands, bacteria and viruses can be prevented from entering from the bottom and sides of the transparent plate. 44. By folding back the ends of the rubber band and Velcro (registered trademark) and fastening them with staples in the specified direction, the Velcro (registered trademark) and rubber band will not come off when attaching or detaching the device, and there is absolutely no risk of injury from the staples. 45. By using a diagonal rubber band glued and fixed to the center of the side of the transparent plate, it does not hurt the ears, and the top and bottom edges of the transparent plate are evenly curved, further suppressing the entry of viruses and bacteria and making the transparent plate less likely to slip. 46. ​​By painting the surface of the staple head 71 the same color as the Velcro (registered trademark) or rubber band, the staples become less noticeable and the appearance is improved. 47. It is lightweight, so you won't get tired even if you wear it for a long time. 48. Allowing sunlight to enter the space between your face and the mask increases the chances of coronavirus dying. 49. It has the effect of being comfortable to wear. 50. The lightest in the world (actual measurement: 17.5 grams) 51. By inserting an explanatory sheet into the transparent plate and a protective sheet that prevents the transparent plate and the hook-and-loop fastener from rubbing against each other, scratches on the transparent plate can be prevented. 52. Furthermore, by placing a protective sheet that is almost twice the size of the transparent plate across both the front and back, scratches on the front and back of the transparent plate can be prevented. 53. When transporting this mask, inserting a reinforcing plate of the same size as the transparent plate in addition to the description will have the effect of preventing the present invention from being destroyed even if external force is applied. 54. The cooling element further raises the temperature of the space between the face and the transparent plate, raising the temperature and pressure between the plates even higher than the outside air, preventing the entry of coronavirus and other viruses while also cooling the forehead, killing two birds with one stone. 55. The angle can be adjusted as desired while the transparent plate is still attached, which allows you to eat by placing food, cups, and other utensils inside the mask while wearing it. It also allows you to apply lipstick. 55. It is effective in completely protecting not only the face but also the head from viral droplets. 56. The transparent plates cover the ears and are effective in protecting against droplets from the sides of the head. 57. The large transparent plate that covers the head can be folded to make it small and easy to carry. 58. When wearing the mask, if the upper transparent plate 47 is raised, it can protect not only the forehead but also the head from splashes. 59. The transparent plate is curved and fixed, so the strength of the upper transparent plate 47 can be increased. 60. The transparent plate contaminated with droplets is carried with the front side facing up, preventing contamination from adhering to the outside and preventing secondary contamination. 61. When removing the mask, you can fold it by holding the elastic strap, which prevents dirt from getting on your hands. 62. By using a bending-resistant material, a heat-reflecting material, and a PSA tape at the joint between the two transparent plates, it is possible to achieve the effect of using it as both a booster and a joint hinge. 63. Multiple transparent plates can be stacked on top of each other, so they will not bend even if there is a strong wind blowing from the front when riding a bicycle or other vehicle. 64. By stacking multiple transparent sheets, the temperature between the sheets increases, the pressure increases, and the mask's ability to prevent and kill viruses increases. It also has the effect of warming the face when it is cold outdoors or indoors in winter. 65. By using two transparent plates stacked on top of each other, even if the front side becomes contaminated with viruses, bacteria, etc., the back side of transparent plate 47 can be used again, making it effective even when the transparent plates cannot be sterilized. 66.It has the effect of being able to be worn upside down. 67. You can turn it around and it works for people with long or short faces. 68. When wearing this mask again after carrying it with you, you can open the folded transparent plate by holding the rubber belt, which has the effect of preventing the new coronavirus, bacteria, etc. from re-adhering to the hand holding it even if droplets have already adhered to the surface of the transparent plate. 69. By stacking two transparent plates with a gap between them, the air layer between the two plates has a heat-retaining effect, raising the temperature in the space between the face and the mask, killing viruses and other microorganisms. It also increases the pressure, creating a pressure difference with the external pressure below and to the sides of the transparent plates, which effectively prevents viruses and other microorganisms from entering. 70. By stacking two transparent plates with a gap between them, it has a heat-retaining effect that prevents heat from escaping from the air between the face and the transparent plates. 71. By folding two transparent sheets and inserting an ultraviolet protection sheet, an infrared protection sheet, a light blocking sheet, a face veil, paper with holes for the eyes, an air freshener sheet, etc. into the gap between the two transparent sheets and wearing it, it has the effects of blocking ultraviolet rays, blocking infrared rays, enabling a good night's sleep, hiding roughness of the face and making the wearer look more beautiful, acting as a substitute for a mask, and providing relaxation with its fragrance. 72. By folding two transparent plates to form two polarizing plates, it is possible to make the inside of the mask less visible and to block out light. 73. By displaying advertising on the transparent board for the head of the two transparent boards, advertising effects can be achieved. 74. By folding back and attaching two transparent plates, the left and right corners of the bottom edge of the transparent plates are made strong against wind pressure, which has the effect of making them usable for motorcycles and bicycles, for example. 75. When two transparent plates are folded and attached, doctors can use them according to the patient's needs, for example, attaching the transparent face plate to the face of a COVID-19 patient and lifting the transparent face plate up for a general patient. 76. When two transparent plates are folded and attached, the connecting tape acts as an identification marker, which has the effect of improving visibility from cars. Furthermore, by using a reflective sheet on the back of the connecting tape, visibility can be further improved. 77. When joining two transparent plates together, using different colors of joining tape on the front and back allows you to instantly determine whether the plates are being used stacked or unfolded. 78. Two transparent sheets can be folded back and paper or other materials can be placed between them to create a file. 79. By wearing it on top of your head, it can be used as a substitute for an umbrella or parasol. 80. Folding and stacking two transparent sheets has the effect of improving strength. 81. The heat-reflecting part where the two transparent plates are joined is folded back to form a double heat-reflecting part, which doubles the amount of reflected heat in the space between the face and the mask, further improving the virus-killing effect. 82. When side cushion parts are installed on the left and right ends of a transparent plate, it acts as a three-point improvement device that increases the temperature, humidity, and air pressure in the space between the transparent plate and the face. 83. By installing side cushions on the left and right ends of a single transparent plate equipped with a head mounting fixture, the overall curvature of the transparent plate is improved, increasing its strength. This has the effect of further improving contamination prevention and durability. 84. Cooler than conventional masks. 85. By providing higher side cushions on the left and right ends of one transparent plate, babies, people with low noses, and people who are mostly bedridden can support the side cushions of the transparent plate with their faces, creating space between the transparent plate and the face, making it comfortable to breathe, and effective in preventing the entry of viruses and killing them. 83. By providing side cushion portions 55 on the left and right ends of transparent plate 46 connected to transparent plate 47, rather than transparent plate 47 with head cushions 59, viruses are prevented from entering from the left and right sides of the transparent plate, the front of the face is protected by transparent plate 46, and the head is protected by transparent plate 47, making it possible to block viruses from entering from all directions.Furthermore, the temperature and humidity in the space between the face and the transparent plate can be further increased, further improving the effectiveness of killing viruses and increasing the air pressure, making it possible to further prevent viruses from entering. 84. This mask is equipped with an ice pack that cools the wearer's forehead, which has the effect of first keeping the wearer cool and comfortable even when worn on a hot summer day, and secondly activating the frontal lobe and improving learning ability. 85. This mask is equipped with ice packs that cool the wearer's temples, which first cools the temples where the arteries pass through, effectively cooling the wearer. In addition, the ice packs act as a barrier to prevent the entry of coronaviruses and other viruses. 86. For example, by attaching a heat-retaining material such as a portable disposable hand warmer to this mask, your face will stay warm even in winter. 87. By attaching a Fresnel lens or the like to the transparent plate of this mask, it can be used as a magnifying glass while providing protection against coronaviruses and other viruses, making it effective for medical professionals as well. 88. By changing the number of times or the direction in which the ice pack or heat pack is wrapped in nonwoven fabric, etc., the cooling and heat retention effect can be adjusted, and the wearer can be prevented from suffering from low-temperature frostbite or low-temperature burns. 89. By placing the cushion part below the top edge of the transparent plate, heat insulating or cooling material can be placed on the cushion part and curved, preventing the heat insulating or cooling material from falling. 90. By tilting both ends of the cushion part at an angle of, for example, 45°, both ends of the transparent plate will cover the head or face without any gaps, preventing the entry of viruses, etc., and providing the significant effect of preventing leakage of temperature, humidity, and air pressure control, which is a feature of this invention. 91. The mask of the present invention does not fog up the face even when ice packs are placed inside. 92. By stacking two thin transparent plates, the plates will not bend even in strong winds, such as when riding a motorcycle. 93. The transparent plates or cushions on the sides of the face fit closely to the sides of the face and chin, effectively preventing the entry of aerosol airborne infections of viruses such as the new coronavirus from the sides or below the face. 94. Effect 93. The belt used acts as a chin rest, preventing the transparent plate from slipping upwards and providing a more secure fixation of the transparent plate to the face. 95. Effect 93. The belt used is effective in preventing the entry of airborne aerosols of viruses such as the new coronavirus from below. 96. Effect 93. By separating the belt and filter, the filter can be fitted to the shape of the face (chin) without any gaps, and it is also effective in preventing the entry of airborne aerosols of viruses such as the new coronavirus. 97. By inserting a sleeve with a filter under the transparent plate, the filter can be easily installed and replaced (Figure 114). 98. Effect 93. By adding a cushion to the belt, it is possible to eliminate the gap under the chin, and it has the effect of providing soft support under the chin and allowing for a snug fit. 99. By integrating the belt cushion of Effect 98 with the vertical side cushions, the gap in the chin area can be further reduced, which has the effect of making manufacturing easier. 100. By making the vertical side cushions have a large inclination, it is possible to eliminate the gap between the transparent plate in the cheek area. 101. Effect 96: By providing the filter of any shape at the bottom of the transparent plate, the filter area can be increased when worn, making breathing easier. It can also be placed inside the collar of clothing, improving the appearance. 102. Effect 96: By using an airtight material and placing the filter only in the center, it is possible to design a filter of any size. Also, by wrapping the filter around the neck like a frill, it can be used to keep out the cold. 102. By making the filter of Effect 101 bag-shaped, it is possible to use an N95 compatible filter, which has the effect of maximally preventing the intrusion of airborne aerosols of viruses such as the new coronavirus, while also making breathing less difficult. 103. By providing a replaceable bag-shaped (bowl-shaped) filter, it is possible to prevent the entry of aerosols of viruses such as the new coronavirus through the air, inexpensively and cleanly. 104. By attaching a replaceable bag-shaped (bowl-shaped) filter to the base of the nose, it is easy to prevent the entry of aerosols of viruses such as the new coronavirus through the air. 105. By dividing and joining a transparent plate to make a mask, it can be folded and carried around. 106. By dividing the transparent plate vertically into four sections, it can be placed in a breast pocket, making it extremely convenient to carry. 107. By providing a storage case that fits the folded shape of Effect 103 and 104, it is possible to carry the mask without viruses such as the new coronavirus attaching to clothes, etc. 108. The cushion is thick and designed to accommodate lenses. By providing a recess for eyeglass lenses in the cushion, eyeglass lenses and scopes do not get in the way of wearing the mask, and the mask can be securely fixed to the head. Furthermore, the transparent plate can be stably positioned perpendicular to the eyes, preventing shaking or distortion of the visual image. 109. By providing a cooling or sweat-absorbing sheet on the thick cushion part, even if the wearer sweats, the sweat is absorbed and the transparent plate does not become stuffy or cloudy. 110. A high cushion with a diagonal V-groove is provided in the center of the transparent plate, so that the transparent plate is supported only by the nose and the transparent plate is separated into upper and lower halves, which effectively prevents viruses from entering through the eyes, nose, and mouth. 111. By pushing open the bent transparent plate and wearing it, the gap between the face and the transparent plate is reduced, which has the effect of preventing the entry of viruses. In addition, no rubber band is required to wear it; simply hook it onto the ears with strings or straps and it will not move. 112. A door is attached to the transparent plate in the area that comes into contact with the wearer's mouth, which has the effect of allowing the wearer to eat while wearing the present invention. 113. The present invention, which is worn when wearing a known mask, is lightweight, can prevent viruses from entering through the eyes, allows eating and drinking, does not make the face hot, and does not hit the body even when the neck (face) is bent at a large angle or when looking down, so it does not slip or come off.

DETAILED DESCRIPTION OF THE INVENTION

[0007] A front view of a person wearing a known mask 1 is shown in FIG. In Figure 1, a mask 1 is used, with the mouth and nose covered with a mask material. The mask has ear loops 2 that are attached to the ears with elastic or string. Conventional masks can only filter out 70% of viruses. Issues include glasses fogging up when breathing, making it difficult to talk, and not being able to prevent viruses from entering the eyes. Furthermore, conventional masks are made of woven or nonwoven fabrics made of fine resin fibers. The idea behind using such fiber masks to remove viruses is that the viruses themselves that have entered the fabric of the conventional masks could become a virus source, or that very small viruses could enter the mouth, making it difficult for conventional masks to prevent viruses. Furthermore, conventional masks only cover the mouth and nose, and do not provide any protection for the eyes. If you are face-to-face with a virus carrier and have a conversation, droplets or breath may get into your eyes, or you may unconsciously touch your eyes. If the virus enters through your eyes, because there are connections between the eyes and nose, nose and mouth, and mouth and throat, it can pass through the nose, mouth, and throat, and even enter the lungs from the throat. Conventional masks that do not protect the eyes cannot protect against viruses.

[0008] To prevent this, goggles are worn in addition to the conventional mask, but the goggles are heavy, the field of view is narrow, and the operation is complicated because the goggles and mask are separate, which is time-consuming, large-scale, and expensive.

[0009] In contrast, the present invention covers the face with a material that is highly transparent and not breathable (specifically, acrylic, plastic, vinyl, OHP sheet, etc.).

[0010] A first embodiment of the present invention will be described with reference to FIGS. FIG. 2 shows the present invention as seen from the inside (the surface to be worn). The transparent thin plate (transparent plate) 4 is a vertically long plate, such as B5 size (182 x 257 mm), large enough to cover the face. Cushioned foam tape is attached with adhesive to the inside of the top of the transparent thin plate 4 (i.e., the side closest to the face). In addition, the ends of a wide rubber band 6 (including buttonhole rubber and round rubber) are fixed or glued to the left and right sides of the transparent thin plate 4. A wide rubber band 6 is fixed to the lower portion of the cushion portion 5. This is because, in FIG. 2, the wide rubber band 6 is fixed by driving staples 7 (so-called stapler (registered trademark)) from the inside to the outside.

[0011] FIG. 5 is a side view of the first embodiment of the present invention, in which a single wide rubber band 6 is fixed to a transparent thin plate 4 by driving staples 71 from the inside outward. This means that the ends of the staples are not in the area that faces the face, so there is no risk of injury to the face.

[0012] The transparent thin plate 4 is made of a transparent and deformable material. For example, it is a flat, bendable plate made of a transparent material such as acrylic, polyester, polyvinyl chloride resin, polypropylene, polyethylene (PE), polystyrene, PET (polyethylene terephthalate), or overhead projector sheet. The surface and inner surface of the plate are smooth, allowing it to be cleaned and sterilized with a spray or other method. Its thickness is preferably approximately 50 microns to 3 mm. The transparent plate of the present invention also includes a film-like transparent body approximately 100 microns thick. The film transparent body has a thickness of 50 to 200 microns. In particular, in the case of Figures 157 to 193, a transparent film of 100 microns or 75 microns is desirable. The film of the present invention is preferably subjected to anti-fogging and anti-reflection (low-reflection) treatment. Anti-fogging is achieved by hydrophilizing the film surface, for example, by coating or incorporating the material into the film. Furthermore, low-reflection treatment is achieved by lowering the refractive index, for example by laminating a film with a moth-eye structure onto the surface. The thickness is set to, for example, about 0.2 mm, so that it can easily conform to the shape of the face and leave gaps around the mouth and nose so that it is not difficult to breathe. It covers the front and sides, and can protect not only the mouth and nose but also the eyes, which is not possible with conventional masks. The size of the transparent thin plate 4 may be other than B5 or A5, and it is used in the vertical or horizontal direction. The transparent thin plate 4 may be transparent only in the area corresponding to the eyes, which makes it possible to use it in applications where it is necessary to conceal the face. Furthermore, the thin plate 4 may have a curved surface shape that is curved left and right or up and down.

[0013] The cushion portion is made of cushion material 51 and adhesive material 52, and is adhered to the transparent plate 4 to improve adhesion to the face and prevent viruses and bacteria from entering from above. As shown in Figures 4 and 5, cushion material 51 comes into contact with the forehead and is made of a material that feels comfortable against the skin even when in contact with the forehead for long periods of time, such as foamed polyurethane. The cushion is, for example, cushion material 51, which is about 15 mm wide and 10 mm thick.

[0014] In addition, it is possible to place an LED anywhere on the cushion, such as on the front exterior, and a battery anywhere inside. This is useful for reading or walking in the dark, and it is visible to other vehicles, improving safety. Also, by attaching reflective material anywhere on the cushion, such as on the front exterior, it becomes more visible to oncoming vehicles at night, improving safety.

[0015] The first embodiment of the present invention uses a transparent thin plate 4, which has a very simple structure, is lightweight, requires little storage space, and is lightweight and thin, making it easy to carry and quickly remove in crowded areas for complete protection against viruses. Furthermore, the mask does not obstruct the wearer's field of vision, and even if a virus carrier speaks directly in front of the wearer, droplets and breath do not reach mucous membranes such as the eyes, nose, and mouth, providing 100% protection against viruses and bacteria. Furthermore, the cushion portion 5 is tightly attached to the forehead, preventing droplets from falling from above and contacting the eyes. Furthermore, the transparent thin plate 4 can be disinfected and reused by wiping. Therefore, even if a conventional mask costs 20 yen, the mask can be discarded once, costing approximately 600 yen per month, or approximately 1,800 yen over three months. This makes the present invention less expensive than conventional masks. Furthermore, since the bottom is open when worn, conversation can be carried out in a normal voice. Also, even if the front is covered with a transparent plate 4, the field of view does not become cloudy because there is an air inlet at the bottom. Also, the headset can be worn over glasses, and the glasses do not fog up. The inflow of bacteria from below the worn product of the present invention is suppressed for the following reasons. (1) Since the coronavirus is transmitted through droplets and not through the air, droplets hit the transparent panel 4 directly, preventing them from entering from below. (2) Even in the case of airborne infection, in the present invention, the temperature of the surface of the face causes the air on the face and inside the transparent plate 4 to expand, increasing the air pressure compared to the outside air. Furthermore, exhaled air is hot, which increases the temperature of the face as well as the temperature inside the transparent plate 4. This causes the temperature of the cushion 5 in contact with the forehead and the air between the transparent plate 4 and the face to rise and expand. In other words, this has the effect of creating a positive pressure state relative to the outside air.

[0016] Next, a second embodiment of the present invention will be described with reference to FIGS.

[0017] FIG. 3 shows the present invention from the user's perspective. The transparent thin plate 4 is long (height) enough to hide the face and is a thin plate 4 that can protect at least the mouth, nose, and eyes. Because it is transparent, it provides good visibility. The head support band is provided here. The ends of the wide rubber band 6 are fixed or adhered near the left and right ends of the transparent thin plate 4. The fixing or adhering may be on either the front or back of the transparent thin plate 4. If this is fastened from the outside with a stapler, the legs of the staples will protrude towards the face and cause facial injury, which is dangerous. The staples may be of any size as long as they can secure the wide rubber band 6 to the transparent thin plate 4. For example, it is preferable to use a size 3 staple (shoulder width 11.5 mm, staple foot 6 mm). Then, the cushion part 5 is placed on top of it and stuck on. It consists of a cushion 51 and adhesive 52, one side of which is adhered to the transparent thin plate 4 with the staple legs protruding, and the other side is adhered to the cushion material 51. That is, the wide rubber band 6 is fixed at the same position as the cushion portion 5.

[0018] Figure 6 is a side view of Figure 3 of the second embodiment, in which the wide rubber band 6 is set in the same position as the cushion part 5, and staples 7 are driven from the outside to the inside to fix the wide rubber band 6 to the transparent thin plate 4, and then the adhesive 57 of the cushion part 5 and the cushion material 56 are stuck on top of it. As a result, there are no protrusions on either the outside or inside of the transparent plate 4, which prevents injuries, etc.

[0019] FIG. 7 is a front view of the second embodiment of the present invention worn on the head and face of a wearer. The transparent thin plate 4 is a deformable thin plate that conforms to the curvature of the face, providing 100% protection from virus and bacterial droplets. The bottom is open, allowing the sound waves of conversation to be transmitted to the outside. The cushion part 5 is shaped and sized to fit snugly against the wearer's forehead to prevent viruses from getting into the eyes. The cushion also prevents pain to the face, and the wide rubber band 6 is wrapped around the head 3 so that it is positioned above the ears, and the rubber strength, thickness, and ring size are sized so that the thin plate 4 does not slip off the face.

[0020] FIG. 9 is a side view of the second embodiment of the present invention attached to the head 3. The thin transparent plate 4 is placed on the face, and the loops of the wide rubber band 6 are placed on the head 3 and attached to the face. Alternatively, the wide rubber band 6 can be attached as a rubber ring by hooking it over the ears, like a known mask. The thin transparent plate 4 is supported by the cushion portion 5 and the nose, creating space in front of the mouth, below the nose, and in front of the mouth, allowing eyeglasses to be worn in the space in front of the eyes and breathing in the space created in front and below the mouth. Furthermore, because space is maintained in front of the eyes, below the nose, and in front of the mouth, the eyes, mouth, and nostrils do not come into contact with the transparent plate 4, so the transparent plate remains clean and can be reused multiple times. Furthermore, the area below the mouth is open, allowing breathing through the nose and mouth, and steam from the mouth escapes downwards, so the transparent plate 4 does not fog up eyeglasses. Furthermore, since the mask does not come into contact with the face, women can wear it even after applying makeup, so women prefer the mask of the present invention to conventional masks. The wide rubber band 6 is positioned above the tip of the nose, and the wide rubber band 6 is adhered to the upper half of the thin plate 4 so that the upper part of the transparent thin plate 4 approaches the forehead. The left and right ends of the transparent thin plate 4 are pulled toward the back of the head by a wide rubber band 6, and curved along the head 3, so that the forehead of the wearer comes into contact with the cushion part 5 without leaving any gap.

[0021] According to the second embodiment of the present invention, the wide rubber band 6 is fixed in the same position as the cushion part 5, which has the effect of allowing the cushion part 5 to fit tightly against the wearer's forehead. Also, since the staples 72 are driven in from the outside toward the inside, no staples protrude from either the outside or the inside, preventing injury.

[0022] A third embodiment of the present invention will be described with reference to FIG. Figure 4 shows an example in which the transparent thin plate 4 is B5 size (182 x 257 mm) and is used with the long side horizontal. The transparent thin plate 4 deforms and provides protection in the horizontal direction, completely preventing splashes from the side and leaving the area below the mouth unobstructed. In Figure 4(A), staples 7 are driven from the outside to the inside of transparent plate 4 and then covered with a cushion to secure both ends of wide rubber band 6, while in Figure 4(B) both ends of wide rubber band 6 are secured with rivets so that the fastening side 73 of the rivet is on the inside of transparent plate 4. When worn, even if the rivets of the rubber band are exposed, the thick cushion prevents the fastening side of the rivet from coming into contact with the skin and causing no injury.

[0023] A fourth embodiment of the present invention will be described with reference to FIG. In FIG. 8, the cushion part 5 on the top of the transparent thin plate 4 is omitted, and belts, elastic cords, etc. are provided at any position above, in the middle, or below the transparent plate 4, and are attached to the ears or other parts of the head. This makes the present invention thin and lightweight, and it can be laid flat or rolled up vertically or horizontally, which is advantageous for storage and transportation, and also reduces costs.

[0024] A fifth embodiment of the present invention will be described with reference to FIGS.

[0025] Figure 10 shows a side view of the present invention worn, in an embodiment where the mask is worn below the eyes to protect only the nose and mouth. This mask is used when there is no risk of droplets getting into the eyes, or when large goggles or large glasses are required. In the fifth embodiment, the vertical length of the transparent plate 4 may be shortened. The transparent plate 4 may be translucent or opaque. The length of the wide rubber band 6 is adjustable so that it can be used either to protect the eyes or to cover only the nose and mouth.

[0026] FIG. 11 is a front view of the sixth embodiment of the present invention when worn. When worn below the eyes, it is necessary to eliminate gaps between the nose and cheeks and the transparent plate 4 when viewed from above, so the sponge at nose height is removed (for example, by making a V-shaped depression) or divided and placed as horizontal left cushion part 53 and horizontal right cushion part 54, thereby improving the fit between the nose and the present invention.

[0027] According to the sixth embodiment of the present invention, it can be used in a form that covers only the nose and mouth. Also, by dividing the sponge, there is an effect that the intrusion of droplets through the gaps between the nose and cheeks and the transparent plate 4 is almost prevented.

[0028] A seventh embodiment of the present invention will be described with reference to FIGS.

[0029] The seventh embodiment of the present invention shown in FIG. 12 is an embodiment in which vertical side cushion portions 55 are provided on three sides of the transparent thin plate 4, on the inside of the upper end and the left and right ends. In Figure 12, the cushion portion 5 at the upper end of the transparent plate (thin transparent plate) 4 is provided inside the transparent plate up to the left and right ends of the transparent plate, and the vertical side cushion portion 55 is provided inside the transparent plate with its upper end extending to the side of the cushion portion 5 and its lower end extending to the lower end of the transparent plate. This will make the world's first baby mask. The transparent plate 4 is small, for example B6, and as described in paragraph number

[0084] , the corners are rounded and cushions are provided on the left and right ends of the transparent plate. Since a baby's nose is not yet developed and is low, the transparent plate 4 cannot be supported by the nose, and furthermore, the baby is mostly facing upwards, so the baby cannot breathe through the transparent plate 4. Therefore, in order to separate the face from the transparent plate 4, a space is created between the face and the transparent plate 4 by the vertical side cushion parts 55 on the left and right ends of the transparent plate 4 and the upper end cushion part 5. For masks for babies, people with low noses, or sleeping people, it is preferable that the cushions 5 and 55 are thick, for example, 20 mm. As an example of how to wear this on the face, the ring-shaped rubber bands 61 are fastened to the left and right ears, and the left and right ends of the transparent thin plate 4 are pulled, and the transparent thin plate 4 is curved, and the vertical and side cushion parts 55 prevent viruses and bacteria from entering from above and from the left and right.

[0030] 13 is a side view of the seventh embodiment of the present invention. The vertical side cushion portion 55 is attached so as to be in contact with the underside of the upper cushion portion 5, and is made up of cushion material 56 and adhesive 57. The length of the vertical side cushion portion 55, including the upper cushion portion 5, may be the same as the vertical length of the transparent thin plate 4, or it may be a length that comes into contact with the temples, corners of the eyes, and cheeks according to the size of the face. The ring-shaped rubber band 61 may be a commercially available rubber band.

[0031] Figure 14 is a side view of the eighth embodiment of the present invention. In this embodiment, the mask is attached to the user using a wide rubber band 6. As in Figure 12, the forehead, temples, and cheeks of the wearer are all in contact with the cushion, providing a significant protection against splashes, just as in the previous example.

[0032] According to the seventh and eighth embodiments of the present invention, vertical side cushion portions 55 are also provided on the sides of the wearer, so that breath or air cannot be sucked in from the sides, further preventing viral infection.

[0033] A ninth embodiment of the present invention will be described with reference to FIG. Figure 15 shows the ninth embodiment of the present invention, (A) a side view of the case with cushion portion 5 and vertical side cushion portion 55, and (B) a front view of the case with cushion portion 5. Instead of one wide rubber band 6, two wide rubber bands are provided on the left and right sides of transparent plate 4, with Velcro (registered trademark) 8 (connecting part such as hook-and-loop fastener) at each end.

[0034] According to the ninth embodiment of the present invention, the headgear can be adjusted to fit the size of the wearer's head using connecting parts such as rubber bands and hook-and-loop fasteners, so that the wearer can freely adjust it without feeling any pressure, it can be easily removed, and the wearer's hair is not disturbed when putting it on or taking it off.

[0035] A tenth embodiment of the present invention will be described with reference to FIG. FIG. 16 is a side view of the tenth embodiment of the present invention. By using a string (including temples) instead of a wide rubber band 6, the transparent plate 4 can be attached with an appropriate tightness regardless of the wearer's head size.

[0036] FIG. 17 is an explanatory diagram showing an eleventh embodiment of the present invention. The wide rubber band 6 is made to be sufficiently longer than the standard head size, and the length of the wide rubber band 6 can be adjusted by pinching the wide rubber band 6 at approximately the center 62, inserting the center 62 of the wide rubber band 6 into the slit 641 of a separately prepared plate-shaped adjustment tool 64 made of rubber or the like and pulling out the wide rubber band 62. The slit 641 tightens the base of the pulled-out wide rubber band 62, thereby fixing the length of the wide rubber band 6. This allows people with different head sizes to use the wide rubber band 6 of the present invention with the same length. In this case, a belt or string may be used instead of the wide rubber band 6, which is the eleventh embodiment of the present invention.

[0037] Figure 18 shows the adhesive fixing structure of the transparent plate 4, wide rubber band 6, and cushion portion 5 according to the twelfth embodiment of the present invention. The end of the wide rubber band 6 is placed on the inner side of the transparent plate 4, which is the side facing the user's face, and is fixed with staples 7. The staples 7 are driven vertically from the outside of the transparent plate so that the staple heads 71 ​​are on the outside of the transparent plate 4 and the staple feet 72 are on the wide rubber band 6. Cushion material 51 is adhered to the end of the wide rubber band 6 and on the staple feet 72 with adhesive 52. Therefore, the staple feet 72 are sandwiched between the sponge portion 7 and the rubber band 6. The end of the wide rubber band 6 attached to the inner side of the transparent plate 4 is, for example, approximately 20 mm wide, and is attached approximately 2 mm below the top edge of the side of the transparent plate 4 and approximately 5 to 20 mm inward from the edge of the side of the transparent plate 4. The staples 7 are driven into the approximate center of the contact area between the wide rubber band 6 and the transparent plate. For example, the position is approximately 1 to 10 mm from the edge of the side of the transparent plate 4, but this is not limited to this. If the end of the wide rubber band 6 and the staple driving position are too close to the edge of the side of the transparent plate, the rubber band may come off or the transparent plate may crack. Furthermore, if the position is too far from the edge of the side of the transparent plate (the staple fixing position is too far inward), it may obstruct the wearer's view, or the transparent plate may not be bent sufficiently, leaving a large gap between the side of the transparent plate and the wearer's side, which is undesirable, and it also increases the cost of the rubber band. The rubber band 6 may be attached to the outside of the transparent plate 6. As described above, the wide rubber band 6 is securely fixed to the transparent plate and the legs 72 of the staples are sandwiched between the sponge part 7 and the rubber band 6, so the face is not injured by the legs of the staples and it is safe, and if the rubber band is placed inside the transparent plate, the aesthetic appearance is not impaired.

[0038] Figure 19 shows a thirteenth embodiment of the present invention, showing that anti-fray tape 65 is wrapped perpendicular to the length of the ends of the wide rubber bands (right) 6R and (left) 6L attached to the left and right sides of the vertical side of the transparent plate 4, as well as the other ends of the two wide rubber bands 6L and 6R. The reason for wrapping the anti-fray tape 65 is that if the long wide rubber bands 6 are cut into shorter lengths during the manufacturing process, the ends will fray. Therefore, the anti-fray tape is wrapped around the parts to be cut in advance, and then the bands are cut at that point. The anti-fray tape 65 is, for example, masking tape, made of paper or other material, and is, for example, about 10 mm wide. As shown in the enlarged cross-sectional view, Velcro (registered trademark) 8, approximately 40 mm long and 20 mm wide, is attached to the wide rubber band (right) 6R and wide rubber band (left) 6L, which have been prevented from fraying by the rubber bands and the fray prevention tape 65, and to the fray prevention tape 65. Of the wide rubber bands attached to the left and right sides of the transparent plate 4, one wide rubber band (right) 6R has Velcro (registered trademark) 8 attached to the outside of the end, and the other wide rubber band (left) 6L has Velcro (registered trademark) 8 attached to the inside of the end. The end of the wide rubber band and the Velcro® may be fastened with a stapler so that the staples face outward, which prevents the Velcro® and the wide rubber band from coming apart after repeated use.

[0039] 20 shows a fourteenth embodiment of the present invention, in which the ends of the wide rubber bands 6 (6L, 6R) fixed to the transparent plate 4 and / or the ends of the wide rubber bands to which Velcro® 8 is attached are folded back to prevent fraying of the wide rubber bands 6. Specifically, the end of the wide rubber band (left) 6L fixed to the transparent plate 4 is folded back, for example, by about 2 to 7 mm and fixed to the transparent plate 4 with staples 7, and the folded back end of the wide rubber band is attached to the cushion material 51 with adhesive 52 of the cushion part 5. In addition, the end of the wide rubber band (left) 6L attached to the Velcro® 8 is also folded back, for example, by about 2 to 7 mm, and the folded back end of the wide rubber band is attached to the Velcro® 8 with Velcro® adhesive 81. Similarly, the end of the wide rubber band (right) 6R is also fixed to the transparent plate 4, adhered to the cushion part 5, and adhered to the Velcro (registered trademark) 8. By folding back the wide rubber band 6, it is possible to further prevent the end of the wide rubber band from fraying, and the appearance is not impaired.

[0040] FIG. 21 is an explanatory diagram showing a fifteenth embodiment of the present invention. In the ninth embodiment, two wide rubber bands 6 are attached to the left and right sides of the transparent plate 4, but in the fifteenth embodiment, only one wide rubber band 6 is used. As shown in Figure 21, one end of one wide rubber band 6 is fixed to the transparent plate 4 with a staple 7 or the like, and Velcro (registered trademark) 8 is attached to the other end of the rubber band, and another Velcro (registered trademark) 8 corresponding to this Velcro (registered trademark) is attached to the other end of the transparent plate 4, not to the part where the wide rubber band 6 is attached. This allows the Velcro (registered trademark) 8 to be fastened on the side of the head when worn, making it easier to operate. Furthermore, there is no need to divide the wide rubber band 6 into two as in the ninth embodiment, making it easier to manufacture.

[0041] FIG. 22 shows a sixteenth embodiment of the present invention, in which the ends of the wide rubber bands 6 (6L, 6R) fixed to the transparent plate 4 of the wide rubber bands of the fourteenth embodiment are not folded back, but are instead attached with double-sided tape 66. Specifically, for example, the end of the wide rubber band 6L is covered from the front to the back with double-sided tape 66, enveloping the cut surface of the end of the wide rubber band 6L, and the front of the end of the wide rubber band 6L is adhered to the transparent plate 4. Then, staples 7 are driven in from the transparent plate side to secure the end of the wide rubber band 6L to the transparent plate 4. Furthermore, the end of the wide rubber band 6L and the staple legs 72 are adhered to the cushioning material 51 with adhesive 52. The double-sided tape 66 on the side (front side) of the end of the wide rubber band 6 that comes into contact with the transparent plate 4 has a width approximately equal to the width of the rubber band and a length of, for example, 5 to 20 mm, and is adhered to the front side of the wide rubber band. The adhesive tape on the side (back side) that comes into contact with the cushion part of the end of the wide rubber band has a width approximately equal to the width of the rubber band and a length of, for example, 2 to 10 mm, and is adhered to the back side of the wide rubber band. By applying double-sided tape 66 long on the front side of the rubber band and short on the back side so as to wrap around the cut end, the end of the wide rubber band does not fray, can be securely fixed to the transparent plate, and also has a strong bond to the cushion, resulting in a good appearance.

[0042] FIG. 23 shows a seventeenth embodiment of the present invention, in which both ends of the Velcro® 8 are fixed with staples to prevent the Velcro® 8 from peeling off the wide rubber band 6. A specific description will be given based on the enlarged cross-sectional view of the portion fixed with staples in FIG. The wide rubber band 6R has a folded end, and the folded end is attached to the Velcro® 8 with adhesive 81 for Velcro®. A staple 7 is driven into one end of the Velcro (registered trademark) 8 so that the head 71 of the staple is on the surface of the Velcro (registered trademark) 8. The foot 72 of the staple is engaged with the folded-back portion of the wide rubber band 6R. Specifically, for example, the end of the Velcro (registered trademark) 8 and the end of the rubber band are bonded together with adhesive 81, a staple is driven into the bonded end of the Velcro (registered trademark) 8, the end of the rubber band 6R is folded back, and the Velcro (registered trademark) 8, the foot of the staple, and the rubber band 6R are bonded together with the Velcro (registered trademark) adhesive 81, thereby achieving the structure shown in the enlarged cross-sectional view. At the other end of the Velcro (registered trademark) 8, a staple head 71 is located on the surface of the rubber band 6R, and a staple 7 is driven in so that the staple foot 72 penetrates and engages the Velcro (registered trademark) 8. This prevents the wide rubber band 6 and the Velcro (registered trademark) 8 from coming apart when opening and closing the Velcro (registered trademark), and also prevents the wearer's head or hands from being injured by the staples as the staples are driven in from a predetermined direction, and also has the effect of preventing the wide rubber band 6R from fraying at its end. The structure of the rubber band 6R and the Velcro (registered trademark) 8 has been described above, but the structure of the rubber band 6L and the Velcro (registered trademark) 8 is also similar. It should be noted that the fixing of the other end of the Velcro (registered trademark) 8 with a staple can be omitted. Alternatively, Velcro (registered trademark) and a wide rubber band may be fastened with staples at one or more locations.

[0043] FIG. 24 shows the seventeenth embodiment of the present invention (FIG. 23) with the rubber bands 6R and 6L fastened around the back of the wearer's head. Figure 24(A) is a view from behind of the joint between rubber bands 6R and 6L at the back of the wearer's head, and Figure 24(B) is a view from the back of the wearer's head of the joint between rubber bands 6R and 6L (a view of the inside of the joint between the rubber bands). Velcro (registered trademark) 8 is fixed to each of the rubber bands 6R and 6L, and the area surrounded by the dotted line shows the Velcro (registered trademark) 8 fixed to 6L. Velcro (registered trademark) is also fixed to the tip ends of the rubber bands 6R and 6L with staples as shown in Figure 23. When peeling off the Velcro® 8 from the rubber bands 6R and 6L to separate them, the rubber band 6L is pulled at position a and peeled off. At this time, each Velcro® 8 will not come off because it is fixed to the rubber bands 6L and 6R with staples. Also, because there are staples at both ends of the Velcro® 8, the Velcro® 8 will not come off the rubber bands even if the Velcro® is joined so that positions a and b are approximately in the same position.

[0044] FIG. 25 shows an 18th embodiment of the present invention, in which the Velcro (registered trademark) 8 is fixed with a stapler and the ends of the Velcro (registered trademark) 8 and the rubber band 6 are folded back and glued together to prevent the Velcro (registered trademark) 8 from peeling off from the wide rubber band 6. An enlarged cross-sectional view of the portion where the rubber band 6R and the Velcro (registered trademark) 8 are fixed with a staple will be described. The structure of one end of the Velcro (registered trademark) 8 is the same as that explained in FIG. 23, so a description thereof will be omitted. The other end of the Velcro (registered trademark) 8 is structured so that it is folded back at the other end, and the folded back portion is fixed with a stapler 7. The stapler is driven in so that the head 71 is on the surface of the rubber band 6. The foot 72 of the staple is engaged with the folded back portion of the Velcro (registered trademark) 8.

[0045] FIG. 26 shows the eighteenth embodiment of the present invention (FIG. 25) with the rubber bands 6R and 6L fastened together with Velcro (registered trademark) 8 at the back of the wearer's head. Figure 26(A) is a view from behind of the joint between rubber bands 6R and 6L at the back of the wearer's head, and Figure 26(B) is a view from the back of the wearer's head of the joint between rubber bands 6R and 6L (a view of the inside of the joint between the rubber bands). In the 18th embodiment of the present invention, the direction in which the staples are driven into the other end of the Velcro (registered trademark) 8 is different from that of the 17th embodiment of the present invention shown in Fig. 24, and as shown in Fig. 26, the staple head 71 is on the surface of the Velcro (registered trademark) 8. Therefore, at position b, there is an additional effect that not only does the Velcro (registered trademark) 8 and the rubber band 6 not come off, but also injury from the staples on the surface of the Velcro (registered trademark) 8 does not occur.

[0046] In the nineteenth embodiment of the present invention, the surface of the staple head 71 is colored to match the color of the surface of the Velcro (registered trademark) 8 and the color of the surface of the rubber band. For example, when the Velcro (registered trademark) 8 and the rubber band 6 are black, black epoxy resin is applied to the surface of the staple 7 and then driven in. This makes it the same black color as Velcro (registered trademark) and rubber bands, which has the effect of making it look good and making staples less noticeable.In addition, the use of epoxy resin means that the color hardly fades.

[0047] FIG. 27 shows the twentieth embodiment of the present invention, in which one piece of Velcro (registered trademark) 8 is adhesively fixed to the transparent plate 4 and the other piece of Velcro (registered trademark) 8 is adhesively fixed to the end of the wide rubber band 6 to prevent the Velcro (registered trademark) 8 from peeling off from the wide rubber band 6. The 20th embodiment uses only one wide rubber band 6, with one end of the wide rubber band 6 fixed to the transparent plate 4 with a stapler 7 or the like, Velcro (registered trademark) 8 attached to the other end of the rubber band, and the end of Velcro (registered trademark) 8 corresponding to this Velcro (registered trademark) 8 fixed with a stapler or the like to the inside of the other end of the transparent plate 4, not the part where the wide rubber band 6 is attached. The enlarged view of part A in Figure 27 is a cross-sectional view at the position where the staple has penetrated, and Velcro (registered trademark) 8 is fixed to the rubber band 6 with staples and adhesive 81 so that it faces the wearer's head, and the end of the rubber band 6 is folded back so that the staple legs do not protrude from the surface. Also, the enlarged view of part B in Figure 27 is a cross-sectional view at the position where the staple has penetrated, but the Velcro (registered trademark) 8 does not have adhesive 81 attached, and is fixed to the transparent plate 4 with a staple, and further, the staple foot and the Velcro (registered trademark) 8 are adhered to the cushion material 51 with adhesive 52. The lengths of the rubber band 6 and the Velcro (registered trademark) 8 are adjusted so that the Velcro (registered trademark) 8 attached to the rubber band and the Velcro (registered trademark) 8 fixed to the transparent plate 4 can be connected at the temples of the head of the wearer of the present invention. As a result, when the connected Velcro (registered trademark) 8 is peeled off to remove the mask, the Velcro (registered trademark) 8 attached to the rubber band 6 and the Velcro (registered trademark) 8 fixed to the transparent plate 4 are both fixed with staples or the like, so there is an effect that the Velcro (registered trademark) 8 will not peel off from the rubber band or the transparent plate. Furthermore, when worn, the Velcro (registered trademark) 8 can be fastened on the side of the head, making it easier to operate. Also, there is no need to divide the wide rubber band 6 into two, making it easier to manufacture.

[0048] Figure 28 shows the 21st embodiment of the present invention, in which there is no cushion portion 5 on the top of the transparent plate 4, and vertical side cushion portions 55 are provided only on the sides. This makes it easier for the transparent plate 4 to bend horizontally. This makes it easier for the vertical side cushion portions 55 to fit tightly against the face on the sides of the head, preventing viruses and bacteria from entering from the sides.

[0049] 29 shows the 22nd embodiment of the present invention, in which left and right cushions 55 or a lower cushion part 58 are provided on the transparent plate 4 in addition to the headrest 5 on the transparent plate 4. This increases the temperature and pressure in the space between the face and the transparent plate 4, further preventing the entry of viruses. Furthermore, in the 154th embodiment of the present invention, the cushion portion is provided with a material to which makeup does not adhere, such as polytetrafluoroethylene PSA tape, thereby preventing makeup from coming off.

[0050] FIG. 30 is a diagram showing the vocalization 24 and breathing 16 states of the present invention. It shows that breathing 16 and vocalization 24 are transmitted to the outside through the lower part 42 of the transparent plate 4, and that breathing is also possible.

[0051] FIG. 31 is a diagram illustrating the operating principle of the present invention. It is thought that viruses such as coronavirus and bacteria may enter through the side 41 and bottom 42 of the transparent plate 4, but the present invention is designed to prevent this. The basis for this is that the present invention uses heat 15 generated from the face due to body temperature to raise the air temperature in the space 25 formed between the transparent plate 4 and the face. As a result, the air pressure P1 in the space 25 becomes higher than the air pressure P2 outside the transparent plate 4, and therefore viruses such as coronavirus and bacteria cannot enter through the side 41 or bottom 42 of the transparent plate 4.

[0052] Figure 32 is a diagram explaining the operating principle of the present invention, in which the transparent plate 4 of the 22nd embodiment is provided with an upper cushion portion 5, vertical side cushion portions 55, and a lower cushion portion 58, which prevents air from flowing out from the sides 41 and bottom 42 of the transparent plate 4 and increases the temperature of the space, thereby further increasing the pressure in the space between the transparent plate 4 and the face compared to the second embodiment (Figure 3) and third embodiment (Figure 4) of the present invention in Figure 31, and making it possible to increase the pressure difference between P1 and P2, thereby further preventing the entry of bacteria and viruses.

[0053] Figure 33 is a diagram explaining the function of the lower cushion 58 of the present invention. The flow of outside air 162 entering the gap between the lower cushion part 58, the transparent plate 4 and the face changes direction three times as shown by the white arrows by the box shape, and the flow is blocked. 1. Hitting the chin (162-1) 2. Hit the transparent board 4 (162-2) 3. Hit the lower cushion part 58 (162-3) This prevents the entry of bacteria, viruses, etc.

[0054] FIG. 34 illustrates the working principle and effect of the present invention for preventing coronavirus by increasing humidity and temperature. In Figure 34, the humidity in the space 25 formed between the transparent plate 4 and the face increases due to moisture 163 contained in the exhaled air and moisture 164 due to the exhaled air, and the temperature also increases due to heat 15 generated from the face due to body temperature. Experiments by the inventor have confirmed that this humidity reaches 50% or more and the temperature reaches 22°C or more (when the body temperature is 36°C). It is known that coronaviruses die at humidity levels of 50% or higher and temperatures of 22°C or higher, so even if coronaviruses enter the transparent plate 4, they will be killed before they reach the nasal cavity or retina, demonstrating the operating principle of the present invention. Additionally, sunlight entering the space between the face and the transparent panel further increases the coronavirus mortality rate.

[0055] A 23rd embodiment of the present invention will be described with reference to FIGS.

[0056] FIG. 35 is a front view of the 23rd embodiment of the present invention attached to the head 3. A transparent bag 10 that allows breathing from the bottom and the back of the head is put over the head 3. The transparent bag 10 is wider than the head 3, and when worn, the bottom end reaches below the chin. The transparent bag 10 can be made of vinyl or polyethylene, as long as the transparent surface is impermeable to air and water. There are no restrictions on the thickness, but it should be thick enough to be firm enough not to block the mouth and nose, for example, 30-300 microns. For example, commercially available 100-micron thick bags can also be used.

[0057] FIG. 36 is a rear view of the transparent bag 10 to be attached to the head 3 shown in FIG. The transparent bag 10 has many holes on the back of the wearer's head to allow air to enter. The number and size of the holes are not limited. For example, circular holes of about 20 mm diameter are evenly spaced in a 3-column x 4-row pattern.

[0058] According to the 23rd embodiment of the present invention, the entire head is completely covered with a transparent bag, which makes it quick and easy to put on and take off, and completely blocks the adhesion and intrusion of droplets from the front and sides. It is lightweight, easy to carry, store, and transport, very simple, inexpensive, and can be reused after sterilization.

[0059] A 24th embodiment of the present invention will be described with reference to FIG. FIG. 37 shows a side view of the present invention. Two large semicircular holes 111 are provided in the rear portion of the transparent bag 10 (on the side of the back of the head when worn). The holes can be cut in one go by folding the center of the transparent bag 10 and cutting it. Then, place the transparent bag 10 over your head 3 so that the unopened side (the left side in Figure 37) is over your eyes, nose, and mouth. When worn, there will be two holes on the back of your head.

[0060] According to the 24th embodiment of the present invention, the opening for breathing is formed by cutting out the bent portion of the transparent bag, which has the advantage that it can be easily made using commercially available transparent bags.

[0061] A 25th embodiment of the present invention will be described with reference to FIGS. FIG. 38 is a side view of the transparent bag 10 folded up and down in the production of the 25th embodiment. The back part of the transparent bag 10 (the side facing the back of the head when worn) is folded and cut in a straight line to form a diamond shape 112. In the case of Example 25, there is no need to create a round shape, so the shape is simple, and it can be cut with scissors without a mold and made on site.

[0062] FIG. 39 is a side view of the completed invention after being unfolded as shown in FIG. In FIG. 38, a diamond-shaped cut is made, so that two large diamond-shaped openings are formed at the rear portion of the transparent bag 10. Then, the transparent bag 10 is placed over the head 3 so that the unopened side of the folded portion (the left side in FIG. 39) is over the eyes, nose, and mouth.

[0063] In this embodiment, the cutout method is a single fold up and down, but it is also possible to fold it multiple times or left and right to form more openings at different positions, which is also included in the embodiments of the present invention.

[0064] According to the 25th embodiment of the present invention, by overlapping and cutting in a straight line, it is possible to easily create a plurality of uniform openings in the rear part (the side of the back of the head when worn) of the transparent bag 10. This has the effect of not only securely holding the head, but also providing appropriate holes for air circulation, and being lightweight and compact and thin when folded, making it easy to store or carry in a pocket, allowing for sudden use in a crowd.

[0065] A 26th embodiment of the present invention will be described with reference to FIGS. FIG. 40 is a view showing the transparent sheet of the 26th embodiment of the present invention in an unfolded state. Adhesive portions 12 are provided at multiple locations on the upper end of the transparent thin plate 4. Also, adhesive tape 13 is provided at the upper center. This is, for example, a single-sided adhesive tape 13 made of foam measuring 10 mm x 50 mm. The transparent thin plate 4 is used in a horizontal position, for example, in the size of B4.

[0066] 41 and 42 show the transparent plate of FIG. 40 adhered to a known hat, sun visor, etc., with FIG. 41 being a view from above and FIG. 40 being a view from the side. The adhesive is achieved by adhering one side of the double-sided adhesive tape 12 shown in Figure 40 to a transparent plate and the other side to the left and right sides of the hat 13, with the tape 13 shown in Figure 40 being adhered to the center of the peak 141. The center of the peak 141 is adhered to the top of the peak and the tape 13 in an L shape as shown in Figure 42. When the wearer puts on the hat or the like 14, their face is protected by the transparent sheet 4.

[0067] The hat or the like 13 may be a sun visor or a helmet. Anything that can be worn on the head 3 and can support the transparent thin plate 4 is included in the present invention.

[0068] The 26th embodiment of the present invention is one that is worn without the wide rubber band 6, and an existing hat, sun visor, etc. 14 can be used, or this part can be specially made, making it easy for the wearer to put on and take off, and also has the effect of simplifying the process by using an existing hat.

[0069] The 27th embodiment of the present invention is an embodiment of the present invention in which a mask is formed three-dimensionally like a toy mask, the eyes are made transparent, and the mask is deformed so that there are no holes in the eyes, nose, or mouth.

[0070] FIG. 43 shows the 28th to 32nd embodiments of the present invention, in which an LED is installed in the present invention.

[0071] 43(A) is a front view of the 28th embodiment of the present invention, in which an LED is provided at the top center of the transparent plate 4, and a battery is provided next to the LED. The LED 17, battery 18, and switch 181 are connected by wiring 19. The LED and battery are provided on the adhesive surface between the wide cushion portion 59 and the transparent plate 4, and are fixed to the transparent plate 4. The light from the LED 17 is emitted through the transparent plate 4. This allows the area in front of the wearer to be illuminated from above the transparent plate 4.

[0072] 43(B) is a front view of the 29th embodiment of the present invention, in which LEDs are provided on the upper part of both sides of the transparent plate 4, and a battery 18 is installed in the center of the cushion part 5. The LEDs 17, battery 18, and switch 181 are connected by wiring 19. Light from the LEDs 17 is emitted through the transparent plate 4. This allows the front to be illuminated widely, including the sides.

[0073] 43(C) is a top view of the 30th embodiment of the present invention, in which an LED 17 is attached to the front surface of the transparent plate 4, and a battery 18 is provided on the adhesive surface between the cushion part 5 and the transparent plate. Wiring 19 passes through the transparent plate 4 and connects the LED 17, the battery, and the switch. This has the effect of allowing the light to be emitted directly rather than passing through the transparent plate 4 in FIG. 43(A), thereby increasing the amount of light.

[0074] Figure 43(D) is a front view of the 31st embodiment of the present invention, in which an LED 17 is provided at the top of the upper surface of the transparent plate 4. The cushion part 5 is adhered to the top of the transparent plate 4, and the LED 17 is adhered to the center of the upper side of the cushion part 5. The battery and switch may be installed in any position. Multiple LEDs 17 may be installed. This allows the light to be irradiated directly and from above, so that a wide area can be strongly irradiated.

[0075] 43(E) is a top view of the 28th embodiment of the present invention, in which the LED 17 is located inside the transparent plate 4 and is installed in the cushion part 5. Light is irradiated through the transparent plate 4. As a result, even if the mask of the present invention is subjected to vibration or impact, the LED 17 will not break down because it is located inside the cushion part 5. Figure 43(F) is a front view of the 32nd embodiment of the present invention, in which an LED 17 is provided below the cushion part on the upper surface of the transparent plate 4. The battery and switch may be installed in any position. Multiple LEDs 17 may be installed.

[0076] FIG. 44 is a front view of the 33rd embodiment of the present invention, in which a reflector or phosphorescent material 20 is adhered to the top of a transparent plate 4. This makes it possible to wear the mask of the present invention safely even in dark places, since the reflector shines in the headlights of a car or the like.

[0077] Figure 45 is a front view of the 34th embodiment of the present invention, in which a reflector or phosphorescent material 20 is adhered to the outside of the transparent plate 4 at the upper cushion part, vertical side cushion parts and / or lower cushion part.

[0078] 46 is a front view of the 35th embodiment of the present invention, in which an L-shaped member 23 is provided on the edge of a vertical side surface inside the transparent plate 4, as shown in the a-a' cross section. The L-shaped member 23 is made of, for example, rubber or plastic. The L-shaped member 23 is adhered to the transparent plate 4. The L-shaped member 23 of the present invention is provided in a portion of 5 to 20 mm from the edge of the transparent plate. By inserting L-shaped members 23 into the side edges to prevent deformation, the strength of the curved transparent plate 4 is increased at the sides, which has the effect of preventing deformation of the transparent plate 4 due to wind, etc. Also, at the bottom and sides of the transparent plate 4, the gap between the wearer's face and the transparent plate 4 is narrowed, which increases the pressure in the gap between the transparent plate 4 and the face, further providing protection against viruses and bacteria.

[0079] FIG. 47 is a cross-sectional view of the 36th embodiment of the present invention, in which the edge surface of the transparent plate 4 is bent. The edge portion of the transparent plate 4 is folded inward. The width of the fold is, for example, 3 mm to 10 mm. This makes it inexpensive and increases the strength of the side surfaces of the transparent plate 4, suppressing deformation of the transparent plate 4, narrowing the gap between the wearer's face and the transparent plate 4 at the bottom and sides of the transparent plate 4, increasing the pressure in the gap between the transparent plate 4 and the face, and further providing protection against viruses and bacteria. The present invention also includes bending the edge portion of the transparent plate 4 into an L-shape or a round shape.

[0080] Figure 48 is a front view of the 37th embodiment of the present invention, in which the upper cushion portion 5 of the transparent plate 4 is made into an enlarged wide cushion portion 59, and a rubber band 6 is glued and fixed to match the position of the lower end of the wide cushion portion 59. The wide cushion portion 59 is, for example, 30 mm wide and 20 mm thick. The width of the rubber band is 20 mm. In FIG. 48, l indicates the length from the bottom end of the transparent plate 4 to the center of the rubber band, and L indicates the vertical length of the transparent plate 4.

[0081] Figure 49 is an explanatory diagram related to Figure 48, and is a top view of the transparent plate 4 when it is worn and curved flexibly. When the transparent plate 4 is worn on the wearer's head and curved to fit the shape of the head at the upper end, w denotes the width, and the transparent plate 4 at the lower end 42, W denotes the width. In Figure 48, it is desirable to set the length l to the center of the rubber band 6 to approximately 1 / 2 of L, as this will allow both the top and bottom of the transparent plate 4 to be curved evenly. By doing so, W in Figure 49 will be approximately equal to w. However, this can cause problems such as the wearer's nose coming into contact with the transparent plate 4 or the rubber band touching the ears. Therefore, in Figure 48, placing the rubber band 6 at the bottom end of the wide cushion 59 contributes to reducing W (reducing the spread of the bottom end of the transparent plate 4) rather than placing the rubber band 6 in the center. This is the 37th embodiment of the present invention. According to the 37th embodiment of the present invention, the gap between the transparent plate 4 and the face is narrowed at the bottom and sides of the transparent plate 4, thereby providing further protection against viruses and bacteria.

[0082] FIG. 50 is a diagram illustrating the structural strengthening that occurs when the present invention is used. The elements that strengthen the structure are: 1. When storing, storing, or carrying (1) Transparent flat plate (2) A thin surface that can be bent (for example, a 0.2 mm thick plate) (3) The skin contact is also flat and thick. (4) Wide band (5) Joint part (6) With upper blocking material 2.When in use (1) By bending a flat transparent plate in the X direction (2) Strengthening in the Y direction (3) A material with a thickness that allows the inside to be compressed (4) Combine (5) Upper isolation material By optimizing the above, the strength of the mask can be increased.

[0083] When stored, stowed, or carried, it is flat and easy to carry, but when in use, it is curved and wrapped around the wearer's head in the circumferential direction (X direction), increasing the strength of the transparent plate in the vertical direction (Y direction). This prevents deformation of the transparent plate due to wind, contact, etc., and makes it less likely to break. Additionally, a mask having one or more of the above elements is included in the present invention.

[0084] FIG. 51 shows the 38th embodiment of the present invention, which is suitable for babies, infants, This invention is for children. It uses a small-sized transparent plate 43 with a safety border 21 at the edge, something that is not found in any masks for babies, infants, or children, including currently known masks. The small-sized transparent plate 43 may be, for example, B6 size or smaller. The safety border 21 may be, for example, a urethane or rubber edge 21, or the edge may be covered with tape. The transparent plate 44 has rounded corners for safety. Furthermore, this rounded-corner transparent plate 44 is provided with a urethane safety border 21. Although there are no known masks for infants, the 38th embodiment of the present invention can be used by children under 18 months old, for the following reasons: 1. Ordinary masks are uncomfortable to wear and are often removed immediately, but the mask of the present invention has open sides 42 and bottom 41 of the transparent plate, making it easy to breathe. 2. The rubber bands and cushions only lightly touch the head and forehead, so even babies will not dislike them. 3. Because the plate is transparent, even the baby wearing it can see what is going on around them, so there is no sense of insecurity. 4. There is no contact with the nose or mouth, so the child does not mind. 5. The baby can cry freely when crying, and at the same time, the mother can hear the baby's voice clearly and respond to the crying immediately. 6. It provides complete protection from droplets from above, even when your baby is sleeping.

[0085] FIG. 52 is a front view of the 39th embodiment of the present invention, in which the lower corners of the transparent plate 4 of the 37th embodiment (FIG. 48) are rounded. This prevents injuries from the corners of the transparent plate 4.

[0086] FIG. 53 is a front view of the fortieth embodiment of the present invention, in which a plasma tape member or an aluminum tape member 22 is adhered to the surface of the transparent plate 4 at the adhesive portion between the transparent plate 4 and the upper cushion. As shown in Figure 53(B), the plasma tape or aluminum tape acts as a booster, reflecting the heat 59 emitted from the face, further increasing the temperature and pressure in the gap between the transparent plate 4 and the face, providing further protection against bacteria and viruses.

[0087] FIG. 54 is a front view of the 41st embodiment of the present invention, in which a rubber band 6 is adhered and fixed to the transparent plate 4 at an angle to the center of the side of the transparent plate 4. The rubber band 6 is slanted because if it is attached straight to the center of the side of the transparent plate 4, it will hit the ear 31 and the transparent plate 4 will be easily displaced, so the rubber band is made slanted and is passed over the ear 31 and fastened at the back of the head. The angle of inclination between the transparent plate 4 and the side surface is, for example, 45 degrees, and the angle is set so that the rubber band is above the wearer's ears. As a result, the transparent plate is not pulled backward at the top but is pulled diagonally backward from the center of the side, so that the upper and lower ends of the transparent plate 4 are curved uniformly and are less likely to slip off, and the pressure in the gap between the transparent plate and the face increases, further preventing bacteria and viruses.

[0088] 55 shows a 42nd embodiment of the present invention, in which at least two rubber bands 6 are glued to one side of the transparent plate 4, and the same number of rubber bands are glued to the other side. One set of rubber bands 6 is glued to the lower part of the side of the transparent plate 4. The other set of rubber bands 6 is glued to the lower end of a wide cushion 59 on the side of the transparent plate 4. This also pulls the lower side of the transparent plate backward, preventing the curve of the lower part of the transparent plate from widening, allowing it to be narrowed, further reducing the gap between the transparent plate and the face. Also, the transparent plate 4 is fixed to the head with two sets of rubber bands, so it can be attached to the face stably without slipping.

[0089] FIG. 56 shows a 43rd embodiment of the present invention, in which rubber bands are adhesively fixed to the side and bottom surfaces of the transparent plate 4. One set of rubber bands 6 is glued and fixed at a position near the center of the side of the transparent plate 4 so that the rubber bands do not come into contact with the ears, and the other set of rubber bands 6 is glued and fixed at both ends of the lower surface of the transparent plate 4. By fixing the lower surface with a rubber band, the chin part of the wearer can also be covered with the transparent plate 4, the gap between the transparent plate and the face can be further reduced, and the transparent plate will not be deformed or its curvature will not spread even in wind or the like.

[0090] 57 and 58 are diagrams illustrating the present invention when the product of the present invention is transported according to the 44th embodiment of the present invention. In Figure 57, the hook-and-loop fastener 8 attached to the end of the rubber band 6 glued to the transparent plate 4 hangs down toward the bottom of the transparent plate inside the transparent plate 4 during transportation and carrying, and may come into contact with the inner surface of the transparent plate 4 and damage the transparent plate 4. Therefore, the 44th embodiment is characterized in that, as shown in Figure 57, a protective sheet 27 is inserted between the inner surface of the transparent plate 4 and the hanging rubber band 6 and hook-and-loop fastener 8, thereby preventing the transparent plate from being scratched by contact. The protective sheet 27 is sized to cover the transparent plate 4. The protective sheet 27 is made of a material that is softer than the transparent plate 4, such as paper, nylon, or soft plastic. The protective sheet 27 may also serve as an instruction manual, and may include illustrations to appeal to users or advertise them. This embodiment is applicable not only during transportation, but also during storage and carrying. The protective sheet 27 may be smaller than the above-mentioned size. good.

[0091] Figure 58(A) shows the state in which almost the entire width of the hook and loop fasteners 8 are fastened together. In order to reliably fix the mask of the present invention to the wearer's head 3, the hook and loop fasteners 8 are fastened together over almost the entire width. 58(B) shows a partial fastening method in which a 1 to 15 mm portion of the hook-and-loop fastener 8 is not pressed strongly. This is the fastening method applied in the 44th embodiment of the present invention. This method does not damage the transparent plate 4, does not get in the way, and allows for easy opening and closing without putting stress on the hook-and-loop fastener 8 or rubber band 6. It may be used for transportation in a packaging bag or for carrying when the present invention is removed.

[0092] Figure 59 shows the 45th embodiment of the present invention, characterized in that the size of the protective sheet of the 44th embodiment (Figure 57) is doubled, folded roughly in the middle, and wrapped with a protective sheet 271 that straddles both sides of the transparent plate. Also, the hook and loop fastener 8 is partially joined as shown in Figure 58(B). As a result, the inner and outer surfaces of the transparent plate 4 are completely covered with the protective sheet 271 and are therefore not damaged.

[0093] Figure 60 shows the 46th embodiment of the present invention, which is characterized in that a reinforcing plate 28 is provided between the protective sheet 27 and the packaging bag 26 in the 44th embodiment (Figure 57(B)) or the 45th embodiment (Figure 59). Also, the hook and loop fasteners 8 are partially joined as shown in Figure 58(B). The reinforcing plate 28 is made of a material that is difficult to deform, such as corrugated cardboard or thin wood. As a result, even if an external force is applied to the mask of the present invention during transportation, the transparent plate 4 is not easily deformed and is not damaged. The configurations of the 44th to 46th embodiments are suitable not only for transportation but also for removing the mask of the present invention for storage or carrying.

[0094] 61 and 62 are diagrams showing a mask according to the 47th embodiment of the present invention, in which a Peltier element device 29 is installed in the cushion portion, being worn. In Figure 61, the low-temperature side 292 of the Peltier element 291 is in direct contact with the wearer's forehead, and the heat dissipation fin 293 provided on the high-temperature side of the Peltier element is closed at the top by the cushion and is open at the bottom, contacting the transparent plate and the air in the space around the face. The Peltier element device 29 is embedded in the bottom of the wide cushion part 59. The battery that drives the Peltier element is a rechargeable storage battery or button battery, and can be placed inside the cushion to make it compact. The switch is placed outside the cushion. FIG. 62 is an explanatory diagram showing that heat generated by the heat radiation fins 293 on the high temperature side in FIG. 61 warms the air in the space between the transparent plate and the face. In the embodiment 47 of this invention, the temperature of the space between the transparent plate 4 and the face is increased by the Peltier element in addition to the temperature of the face, which makes the pressure in the space 25 between the transparent plate 4 and the face higher than the outside air, preventing the invasion of coronaviruses and the like, and the temperature increase kills any coronaviruses that may have entered the space between the transparent plate and the face. In addition, the forehead is cooled, providing a cooling effect even in summer.

[0095] Figure 63 shows the 48th embodiment of the present invention, characterized in that the rubber band that holds the head can be shifted or curved, the contact part between the cushion part and the forehead can be shifted above the head, and the support part can change the angle of the transparent plate 4 as desired. The angle of the transparent plate 4 can be changed, and by opening the transparent plate 4 widely, it is possible to put food or tableware such as a cup 32 inside the mask and eat. It also has the effect of allowing lipstick to be applied.

[0096] Figures 64 to 66 show the 49th embodiment of the present invention, in which a transparent plate 4 covers the head. For example, if the transparent plate in other embodiments of the present invention is B5 size, in this embodiment the transparent plate is twice that size, B4 size, and this invention protects the head and ears from splashes, making it an important invention for doctors. In FIG. 64, a cushion part 5 is provided in the approximate center of a B4 size transparent plate 45, and rubber bands 6 fixed to the transparent plate 45 are placed on both ends of the cushion part. As shown in Figures 65 and 66, the transparent plate is large, so the head and the sides of the ears are also protected by the transparent plate. In addition, for example, when using a transparent plate made of a single A4 sheet placed vertically, the standard distance from the top edge of the transparent plate to the part that comes into contact with the head or face is, for example, 7 cm. This provides 100% protection from the head to the chin against droplets from the front, and prevents droplets from the sides from hitting the ears, making it extremely useful for doctors.

[0097] Figure 67 shows the 50th and 58th embodiments of the present invention, with the 50th embodiment being the same as Figure 67 but without the reflector 20. The 50th embodiment is characterized in that instead of using a transparent plate twice the size of the single plate described above, two transparent plates are joined together to form a larger transparent plate, with another transparent plate 47 joined to the upper end of transparent plate 46 so that it can be rotated and folded. The size of the transparent plates is, for example, B5 size, but when two plates are joined together it becomes B4 size. A cushion part 59 and a rubber band 6 are attached to the transparent plate 46, for example, as in the 37th embodiment of the present invention, and the bottom end of the other transparent plate 47 and the top end of the transparent plate 46 are adhesively fixed with PSA tape or the like 30 so that they can rotate. When not in use, the two transparent plates 46 and 47 can be folded with their front sides overlapping, reducing the mask to half its original size for easy portability. The overlapping of the two transparent plates provides high strength. Furthermore, when worn, the upper transparent plate 47 can be raised to protect not only the face but also the top of the head, making it extremely useful for medical use. By simultaneously curving the two transparent plates, the separate and weak transparent plates 46 and 47 are strengthened and erected to the same cross section, making this a significant invention. Furthermore, since the two transparent plates are carried with their surfaces overlapping each other even if they are contaminated by droplets, this significantly reduces contamination and prevents secondary contamination from adhering to the outside. Furthermore, when removing the mask, the mask can be folded by holding the rubber strap, preventing contamination from transferring to the handle. The two transparent plates may be of different sizes, and may be made of a material such as a polarizing plate, and a plurality of plates may be joined together. In the 58th embodiment, as shown in FIG. 67, a reflective material 20 is adhered onto a PSA tape or the like 30.

[0098] Figure 68 shows the 51st embodiment of the present invention, in which two transparent plates are joined together using a booster 221. This is the 50th embodiment of the present invention, characterized in that the two transparent plates are joined together using a booster 221 that increases the temperature of the space between the face and the transparent plates. The booster is, for example, made by laminating an aluminum layer and a glass cloth layer and coating it with a PSA layer. A plasma tape may be used. By laminating the glass cloth, the heat-reflective material is given repeated bending strength, so that the transparent plate will not break no matter how many times it is folded. Also, since the heat-reflective material is laminated, it serves as a booster to further increase the temperature and pressure in the space between the face and the transparent plate. Also, the PSA serves to hinge-bond the transparent plates.

[0099] FIG. 69(A) is a side cross-sectional view of the 51st embodiment (FIG. 68), and the length from the upper part of the cushion part 59 to the lower end of the transparent plate 46 is defined as d. FIG. 69(B) shows the 52nd embodiment of the present invention, characterized in that a cushion part is provided on one of the two transparent plates of the same size, for example, joined by a hinge. Specifically, for example, a wide cushion part 59 and a rubber band 6 (shown by a dotted line) are attached to the lower end of the upper transparent plate 47 in the same manner as in the 37th embodiment of the present invention at the time of wearing, and the lower end of the transparent plate 47 and the upper end of the transparent plate 46 are adhered with a booster (for example, a heat-reflective tape laminated with glass cloth and aluminum) 221 so as to be rotatable. The lower transparent plate 46 is not provided with a mounting tool such as a rubber band. FIG. 69(B) is a side cross-sectional view of this embodiment, and the length from the upper part of the cushion part 59 to the lower end of the transparent plate 46 is defined as D. That is, if FIG. 69(A) is turned over and worn as shown in FIG. 69(B), even if the two transparent plates are of the same size, d < D, and the position of the mounting tool is shifted to one side, the length covering the face of the transparent plate can be increased, and it can accommodate people with long faces. Conversely, if it is worn in the reverse direction as shown in FIG. 69(A), it will be the size of a face protection transparent plate suitable for people with short faces. Furthermore, when the mask is carried and then reinstalled, the rubber band 6 can be used to open the folded transparent plate, so that even if droplets of the new coronavirus or the like have adhered to the surfaces of the transparent plates 46 and 47, the reattachment of the coronavirus, bacteria, etc. to the hand holding the mask of the present invention can be prevented.

[0100] FIG. 70 shows a 53rd embodiment of the present invention, characterized in that a reflector 20 is disposed at the joint between two transparent plates. Figure 70(A) is a front view of two transparent plates unfolded, Figure 70(B) is a front view of them folded and stacked, and Figure 70(C) is a cross-sectional view of them folded and stacked. Of the two transparent plates, a reflecting material 20 is attached to the back surface of the joint of the transparent plate that does not have a cushion portion. For example, it is attached to the back of the transparent plate 47 corresponding to the upper half of the booster (for example, a heat reflective tape made by laminating glass cloth and aluminum) 221 attached to the joint between two transparent plates. The reason is that if the reflective material 20 is attached to the front side, it will hide the label and the booster 221, but if it is attached to the back of the transparent plate 47 for the head of the transparent plate, this will not happen. As a result, when the transparent plate 47 is folded back, the reflective material 20 appears on the outside, improving visibility from cars at night. The reflective material can be attached to the entire back side of the width of the joint of the transparent plate 47, which has the effect of increasing the reflective effect. Instead of the reflective material, a phosphorescent material may be used.

[0101] FIG. 71 shows the 54th embodiment of the present invention, characterized in that papers and the like are filed in the gap between two transparent plates. FIG. 71(A) shows two transparent plates 46 and 47 folded together with a paper 33 filed in the gap. This has the effect of allowing papers and the like to be organized in the gap between the two folded transparent plates and then stored or moved. Figure 71(B) shows two transparent plates 46, 47 spaced apart and joined together with a bonding booster heat reflective tape 221, so that the gap between them is wider when the two transparent plates are folded, and paper 33 or the like is filed inside. This allows you to file large amounts of paper, etc., and the rounded joints increase the folding strength, providing a great booster effect when unfolded and worn.

[0102] Figures 72(A) and (B) show a 55th embodiment of the present invention, which is a cross-sectional side view, characterized in that a shielding material 34 such as paper, a filter, or cloth can be inserted into the gap between two overlapping transparent plates 46 and 47. In FIG. 72(A), by inserting a filter 342 that blocks ultraviolet rays into the gap between two transparent plates, it is possible to provide strong protection against ultraviolet rays from the sun outside, and it has the effect of functioning as a sun visor. In addition, by inserting an infrared-blocking filter 343, it can be used as a mask for work in welding factories, glass processing, etc. It can also be used at home to protect against the heat of stoves and sunlight. Furthermore, inserting a face veil, lace or other fabric 344 will have the effect of making the woman's face look even more beautiful at a party or the like. In addition, by inserting a paper mask 345 with holes for the wearer's eyes, it becomes a mask. Furthermore, by inserting an opaque light-blocking material 341 such as paper and wearing the mask of the present invention when going to bed as shown in Figure 72(B), it acts as an eye mask, blocking out external light and allowing you to sleep soundly.

[0103] FIG. 73 shows the 56th embodiment of the present invention, characterized in that the transparent plates 46, 47 are facing upward and are worn on the head. In Figure 73(A), a transparent plate is placed on the head and secured to the chin with a rubber band 6 and hook-and-loop fastener 8 to create an umbrella. In Figure 73(B), a light-blocking plate 35 such as cloth or paper is placed on the outside or inside of a transparent plate, and the mask of the present invention is placed on the head and secured to the chin with a rubber band 6 and hook-and-loop fastener 8 to create a parasol. As a result, even if you do not need to carry an umbrella or a hat, by carrying the lightweight and compact mask of the present invention, you can prevent getting wet in a sudden rain, etc., and it also has the effect of protecting you from ultraviolet rays instead of a hat.

[0104] Figure 74 shows the 57th embodiment of the present invention, characterized in that the booster (for example, a heat-reflective tape laminated with glass cloth and aluminum) that connects the two transparent plates 46, 47 has different colors on the front and back, making it possible to immediately determine whether the two transparent plates are overlapping or spread apart. For example, the booster (heat-reflecting tape) 222 that connects two transparent plates has a silver surface and a white back surface, and when the two transparent plates are opened and unfolded (Figure 74(A)), a silver stripe is visible, and when the two transparent plates are folded and doubled (Figure 74(B)), a white stripe is visible, which has the effect of making it possible to instantly determine whether the two transparent plates are opened and unfolded or whether the two plates have been folded and become one.

[0105] Figure 75 shows the 58th embodiment of the present invention, in which, instead of a transparent plate 47 with a head cushion 59 attached, side cushion portions 55 are provided on the left and right ends of a transparent plate 46 connected to the transparent plate 47 as shown in Figure 75. As a result, the vertical and side cushions 55 can prevent the novel coronavirus and other viruses from entering from the left and right sides of the transparent plate 46. In addition, the transparent plate 46 can protect against the novel coronavirus and other viruses from the front of the face, and the transparent plate 47 can protect against the front of the head, making it possible to obtain a perfect professional mask that can prevent the novel coronavirus and other viruses from entering from all directions.

[0106] In the 59th embodiment of the present invention, as shown in Figure 76, the vertical side cushion portions 55 at the left and right ends of the transparent plate (thin transparent plate) 4 extend to the upper and lower ends of the transparent plate and are provided on the transparent plate, and both left and right ends of the cushion portion 5 are provided to the sides of the vertical side cushion portions 55. In addition, rubber bands etc. (6, 6R, 6L, 61, 63) are fixed to the transparent plate 4 at the position of the cushion portion 5 at the upper end of the transparent plate 4 or at appropriate positions on the vertical side cushion portion 55. In Figure 76, the transparent plate and rubber bands etc. are fixed at the upper end of the transparent plate 4 below the vertical side cushion portion. According to the 59th embodiment of the present invention, first, by installing side cushion parts on the left and right ends of the transparent plate, it has the effect of functioning as a three-point improvement device that increases the temperature, humidity, and air pressure in the space between the transparent plate and the face. Secondly, by attaching the head mounting fixture to the three-point elevating device, the degree of curvature of the entire surface of the transparent plate is improved, which has the effect of improving its strength. Third, this improves both contamination resistance and durability, helping to protect medical workers. Fourth, it is cooler than conventional masks and is therefore easier to use.

[0107] The 60th embodiment of the present invention is characterized by providing a cold insulation material in the cushion portion of the transparent plate 4. Figure 77(A) is a view from the inside of the transparent plate, showing that a cold insulation material 38 is provided in the cushion portion 59 at the upper end of the transparent plate 4. As shown in the side cross-sectional view of part AA', a cold insulation material is provided on the surface of the wide cushion portion 59. Figure 77(B) shows that when wearing the mask of the present invention, the ice pack 38 comes into contact with the wearer's forehead, and the ice pack is arranged so that the ice pack 38 comes into contact with the part of the wearer's forehead. FIG. 77(C) shows the shape of the ice pack 38 provided in the mask of the present invention, and for example, a rectangular gel-like ice pack 14 cm long and 5 cm wide is used. The ice pack 38 is fixed to the cushion portion of the ice pack 38 by a known method. Alternatively, the ice pack 38 may be placed in a gap formed in the cushion portion. If frostbite is a concern, you can wrap the ice pack in cloth beforehand. According to the 60th embodiment of the present invention, it has the effect of being able to be worn and stay cool even in the hot summer. It also has the effect of activating the frontal lobe and improving learning ability. Furthermore, it can be used as a simple facial cooling device. If a portable disposable warmer is used instead of the ice pack 38, it can be used in cold regions.

[0108] The 61st embodiment of the present invention is characterized in that the ice pack bag 37 is attached to the transparent plate and the ice pack comes into contact with the forehead, and as shown in Fig. 78(A), the ice pack bag 37 is fixed to the transparent plate 4 and the cushion part 59 with double-sided adhesive tape 372 on the inside of the transparent plate 4, and the ice pack 38 can be inserted into the ice pack bag 37 facing downward. As shown in Fig. 78(B), when wearing the present invention, the ice pack bag 37 is folded toward the part of the cushion part 59 that comes into contact with the forehead, and the mask of the present invention is fixed to the head with the rubber band 6 in a state where the ice pack 38 is sandwiched between the forehead and the cushion part. This has the effect of allowing the forehead to be cooled by the ice pack, and the ice pack can be easily attached and detached from the mask of the present invention.Furthermore, the ice pack is hardly noticeable when viewed from the front of the wearer, so it looks good. The ice pack bag 37 does not need to have an inlet fastener 371 such as a zipper, hook, or button (see, for example, Figures 80 and 81).

[0109] In the 62nd embodiment of the present invention, as shown in FIG. 79, a cold insulation bag 37 is provided on the upper side.

[0110] In the 63rd embodiment of the present invention, as shown in Figures 82 and 83(A), ice packs 37 are attached to the vertical side surfaces of the left and right ends of a transparent plate and joined with PSA tape. Also, as shown in Figures 82(B) and 83(C), when the mask of the present invention is worn, the temples are cooled by ice packs 38 inserted in the ice packs 37. Figure 82 uses a square ice pack, while Figure 83 uses a long, thin ice pack. This also cools the temples of the wearer, making it possible to wear the present invention more comfortably even in the hot summer, and also preventing viruses from entering from the sides.

[0111] The 64th embodiment of the present invention, as shown in Figure 84, cools both the forehead and temples. The arrow indicates the direction in which the ice pack is inserted. Heat packs such as hand warmers may be used instead of the ice packs.

[0112] In the 65th embodiment of the present invention, as shown in FIG. 85, the ice pack 37 is directly bonded to the transparent plate 48.

[0113] In the 66th embodiment of the present invention, as shown in FIG. 86, a material 39 to which foreign matter such as tetrafluoroethylene does not adhere is placed between the ice pack and the forehead. Specifically, a polytetrafluoroethylene (PSA) tape 39 is attached to a bag 37 containing ice packs 38. This reduces the cold air by preventing the ice packs from directly contacting the forehead, preventing low-temperature frostbite and also preventing the attachment of viruses and the like.

[0114] In the 67th embodiment of the present invention, as shown in Figure 87, a foam material 391 is used instead of the tetrafluoroethylene 39. As the foam material is thick, a space is created between the ice pack and the forehead, further mitigating the cold air.

[0115] As shown in FIG. 88, the 68th embodiment of the present invention is an embodiment in which a cold insulation or heat insulation material retaining material 591 is provided inside the head cushion 59, an opening 373 is provided between the two, cold insulation material and heat insulation material 38 are inserted, and a bottom retaining part 592 for the cold insulation material and heat insulation material is provided at the bottom.

[0116] As shown in FIG. 89, the 69th embodiment of the present invention is an embodiment in which a head or face contact cushion 59 and a rubber band 6 are provided at a position approximately 1 / 3 of the way up a transparent board 45 for B4 portrait orientation, and a bag 37 for cold and heat insulation materials is provided, with cold insulation materials 38 placed in the bag 37 and placed on top of the head or face contact cushion 59.

[0117] In the 70th embodiment of the present invention, as shown in FIG. 90, two transparent plates of B5 size, for example, are used horizontally and joined so as to be flexible with a tape 30 made of tetrafluoroethylene, polyimide (for example, trademarked Kapton), or polyester (for example, trademarked Mylar), PSA, or the like, and a bag 37 for ice or heat insulation material is provided at the position of the transparent plate for the head 47, and ice or the like 38 is inserted from an opening 373 at the top of the bag 37 and placed on the head or face contact part 59. This has the effect of preventing the face panel 46 from fogging up.

[0118] As shown in Figure 91, the 71st embodiment of the present invention is an embodiment in which two transparent plates are joined together as in Figure 90, a bag 37 for ice or heat insulation material is provided, the ice insulation material is inserted and placed on the head or face contact part 59, and the position of the head or face contact part 59 is set away from the joint part 49 of the transparent plates (d). This shortens the length of the transparent plate 47 in the head cooling section and lengthens the length of the face section, so that the face is adequately covered and the area of ​​the transparent plate 47 that becomes cloudy due to the cooling section is reduced, while still providing sufficient protection from viruses, etc.

[0119] The 72nd embodiment of the present invention, as shown in FIG. 92, is an embodiment in which two transparent plates are joined together as in FIG. 90, and the ice pack 38 is placed on the head or face contact portion 59 without providing a bag for the ice pack and heat pack.

[0120] The 73rd embodiment of the present invention is an embodiment in which a transparent plate is provided with vertical side cushion portions 55 and a cold insulation bag 37 is provided on the side of the transparent plate 4, as shown in FIG.

[0121] The 74th embodiment of the present invention, as shown in Figures 94-95, is a B4-sized transparent plate 45 used vertically, with a cold pack bag 37 (for example, a white nonwoven fabric or a nonwoven fabric dyed a concealing color such as black) provided above the center of the transparent plate 45 (Figure 94), and the cold pack 38 is inserted and wrapped in the bag 37, placed on the head or face contact part 59, and leaned against both the transparent plate 45 and the head or face contact part 59 (Figure 95). Depending on how the bag 37 for the ice pack or heat pack 38 is wrapped, the number of sheets placed between the human body and the ice pack holder can be adjusted from one sheet of nonwoven fabric as shown in Figure 95(A) to three sheets as shown in Figure 95(B), by wrapping more as shown. This allows the degree of coolness or warmth to be adjusted.

[0122] As shown in Figures 96 to 98, the 75th embodiment of the present invention uses a transparent plate 48 of A4 size used horizontally with rounded corners, and provides a bag 37 for cold insulation or heat insulation material made of nonwoven fabric or transparent plastic with a pattern in black or other colors, in which cold insulation or heat insulation material or other small items such as cards, business cards, bills, coins, documents, smartphones, cosmetics, tissues, etc. can be stored. The size of the transparent plate can be, for example, A4 size in landscape orientation, and the transparent plate can protrude, for example, 15 mm above the head contact area to serve as a plate to prevent the cooling or heat insulating material from falling. The standard width of the rounded transparent plate is, for example, 297 mm, the standard height is, for example, 210 mm, and the standard thickness is, for example, 0.5 mm; the standard distance from the top of the part that comes into contact with the head or face to the top of the transparent plate is, for example, 15 mm; the standard width of the bag for the ice pack and heat pack is, for example, 180 mm; and the standard length from the top of the part that comes into contact with the head or face to the top of the storage bag is, for example, 110 mm, but this is not limited to these. The ice pack, heat insulator, or container (called ice pack, etc.) placed in the ice pack bag is rolled up and placed on top of the cushion part, and is loosely in contact with the wearer's forehead. The opening 373 of the ice pack may be oriented sideways ((A), (B)) as shown in FIG. 96 or upward ((C), (D)). In addition, the size of the transparent plate can be, for example, A4 size in landscape orientation, and the transparent plate can protrude, for example, 15 mm above the head contact area to serve as a plate to prevent cooling or heat insulating materials from falling.

[0123] 97 is a diagram of the 75th embodiment of the present invention, in which a cold pack, a heat pack, or a small item 38 is inserted into a bag 37, rolled up, and leaned against the transparent plate 48 and the head or face contact portion 594. The cold pack, etc., does not need to be fixed to the cushion portion, as it curves along the wearer's head when worn, and will not fall off. The ice pack does not come into direct contact with the forehead, but rather comes into contact with it with some gaps, so it does not damage the skin with low-temperature frostbite or the like. Wearing the device with the nonwoven fabric of the ice pack bag on the forehead side in the single layer (A) provides a strong cooling effect, while wearing it with the nonwoven fabric of the ice pack bag in the triple layer (B) provides a gentle cooling effect, so the wearer can choose which to use.

[0124] Figure 98 is a diagram of the 75th embodiment of the present invention, showing specific dimensions in centimeters. Of course, dimensions other than these are also included in the present invention.

[0125] The 76th embodiment of the present invention is an embodiment in which both ends of the head or face contact portion 594 are inclined at an angle of, for example, 45°, as shown in FIG. As a result, as shown in Figure 99(B), both side edges of the transparent plate 45 completely cover the head or face, preventing the entry of viruses and the like, and also providing the significant effect of preventing leakage of temperature, humidity, and air pressure control, which is a feature of the present invention.

[0126] The 77th embodiment of the present invention is a rectangular or square ice pack as shown in FIG. 100, showing specific dimensions, for example. (A) is rectangular, for example, approximately 14 x 6 cm. (B) is a rectangle made by joining two squares, for example, approximately 14 x 6 cm. (C) is a square, for example, approximately 7 x 6 cm. The above (A) to (C) are solid granular ice insulation materials. (D) is rectangular, for example, approximately 14 x 5 cm. (D) is a blue gel-like material. Experiments have shown that this gel-like material can be cooled for a long time, is flexible, and has a good aesthetic appearance.

[0127] In the 78th embodiment of the present invention, instead of two B5 size sheets connected with tape as shown in Figure 92, one A4 size sheet is used vertically, and the length above the rubber band is set to, for example, 7 cm (not shown).

[0128] The 79th embodiment of the present invention is an embodiment in which a lens 90 such as a Fresnel lens is provided inside the transparent plate 4, as shown in FIG. The Fresnel lens can be attached by using double-sided transparent adhesive tape around the lens (see Figures 101-104) or by using an arm (see Figures 105 and 106). Due to the focal length, the cushion portion 593 is made thicker to increase the distance between the eyes and the Fresnel lens. The mask of the present invention allows for magnified vision while protecting against droplets of coronavirus and other viruses, thereby preventing viral infection among medical workers.

[0129] In the eightieth embodiment of the present invention, as shown in FIG. 102, a lens 90 such as a Fresnel lens is provided inside the transparent head plate 47 made of two transparent plates. When using the present invention as a mask, the face transparent plate 46 and the head transparent plate 47 are curved and placed on the same plane as shown in Figures 102(A) and (B), and when using a Fresnel lens, the face transparent plate 46 and the head transparent plate 47 are folded and placed as shown in Figures 102(C) and (D).

[0130] In the 81st embodiment of the present invention, as shown in FIG. 103, the width of the joint between the two transparent plates is narrowed, so that the head transparent plate 47 can be folded over the face transparent plate 46 while the mask of the present invention is still being worn. Since the connecting tape 30 is attached only to the center of the transparent plate, tape is attached to the front and back of the transparent plate to ensure strength. Also, by attaching the transparent plates 46 and 47 with a gap between them, they can be easily folded over, and the distance between the eye and the Fresnel lens can be increased.

[0131] The 82nd embodiment of the present invention, as shown in FIG. 104, is a B4 size vertically mounted transparent plate 45, with a head or face contact portion 592 provided above the center of the transparent plate 45 and a Fresnel lens or other lens 90 provided in the center. By using B4 vertically, the transparent plate can be tilted and the distance to the Fresnel lens increased, allowing for focusing.

[0132] 105, the 83rd embodiment of the present invention is such that a Fresnel lens attachment 901 is provided on the upper end of a transparent plate 4 and a lens 90 such as a Fresnel lens is provided in front of the transparent plate 4. The Fresnel lens attachment 901 is a movable lens arm that is attached by being clamped to the transparent plate.

[0133] In the 84th embodiment of the present invention, as shown in FIG. 106, a B4 size vertically mounted transparent plate 45 is provided with a Fresnel lens attachment 901 at the upper end of the transparent plate 45 and a lens 90 such as a Fresnel lens is provided in front of the transparent plate 45. This allows the Fresnel lens to be used over a wider range and makes it easier to focus the Fresnel lens.

[0134] The 85th embodiment of the present invention is characterized in that the lower part of the transparent plate is curved toward the jaw side in order to reduce air and water resistance (not shown in the figure, see Figs. 10 and 11).

[0135] The 86th embodiment of the present invention is a mask characterized in that the transparent plate extends over the entire face and has a forehead support such as a cushion when the transparent plate touches the forehead (not shown in particular, see Figs. 10 and 11).

[0136] This is the 87th embodiment of the present invention, and is a mask characterized by the elimination of the cushion or other forehead support portion of the 86th embodiment (not shown in particular. See Figures 10 and 11).

[0137] The 88th embodiment of the present invention is characterized in that a bib-shaped sheet (made of a material such as a vinyl sheet, cloth, nonwoven fabric, or N95 filter) 1000 is provided at the lower end of the transparent plate 4, as shown in FIG. (A) is a front view of the bib-shaped sheet 1000 attached to the lower end of the transparent plate 4 across the entire width, and (B) is a front view of the bib-shaped sheet 1000 with a window in part and an N95 filter 1095 attached. The bib-shaped sheet 1000 is attached, for example, to the bottom edge of a transparent plate with a width of about 5 mm using double-sided tape. The size of the bib-like sheet 1000 is such that its width is approximately the same as that of the transparent plate, and its length is approximately the same as that of the transparent plate so that the gap between the transparent plate and the throat under the chin is covered when the present invention is worn. Specifically, assuming B5 size, the size of the bib-like sheet 1000 is preferably a nonwoven fabric sheet with a width of approximately 250 mm, a length from the bottom edge of the transparent plate to the bottom edge of the bib-like sheet of approximately 200 mm, and a thickness of approximately 1 mm. The material of the bib-like sheet 1000 may be a flexible material that is airtight, such as a vinyl sheet, or an airtight material, such as cloth or nonwoven fabric, or even an airtight material such as a filtering material, such as an N95 filter. It is preferable that the entire surface or a part of the bib-like sheet 1000 serves as a filter. The bib-like sheet 1000 may be hung in front of clothing or tucked into a jacket. According to the 88th embodiment (A) of the present invention, the use of a material that allows air to pass through and filters the air, making breathing comfortable, and the gap between the transparent plate under the chin and the throat, through which air can pass, prevents aerosol airborne infection of the novel coronavirus. Furthermore, the use of an airtight material blocks cold air from the wind around the neck in winter, keeping the wearer warm. Furthermore, placing the mask inside a jacket or other garment effectively maintains a tight seal without the filter getting in the way. According to (B) of the 88th embodiment of the present invention, breathing is not difficult, aerosol airborne infection of the new coronavirus can be prevented, and the mask has the dual effect of maintaining a tight seal around the neck and keeping the wearer warm.

[0138] The 89th embodiment of the present invention, as shown in Figures 108 to 111, is characterized in that the curvature of the transparent plate is narrowed to prevent aerosol airborne infection of the new coronavirus from the sides of the face and chin.

[0139] As shown in front views 108 and 109 (rear view), the transparent face plate 46 is, for example, an A4 size sheet oriented horizontally, and a long, horizontally long transparent head plate 47, half the size of the short side of an A4 sheet, is joined to the top of the transparent face plate 46 with a folded connecting tape 30, and rubber bands 6 are fixed with staples and adhesive at both ends of the forehead contact cushion 59 so that they are sandwiched between the cushion 59 and the transparent plate 46. In addition, a cooling bag 37 made of black nonwoven fabric or the like is provided between the transparent head plate 47 and the cushion portion 59, so that the user can wear the mask comfortably even in summer. A forehead cushion 59, vertical side cushions 55, and lower cushion 58 are provided on the top, side, and bottom edges of the inside of the transparent plate 46. A belt 67 is adhered to the outside of the bottom side of the transparent plate 46 with double-sided adhesive 66, and a thin Velcro strip is attached to the other end of the belt 67 with the soft side facing up in one place, or if it is round Velcro, in multiple places with adhesive. Meanwhile, a round Velcro strip 8 is attached to the bottom side of the other end of the transparent plate 46 with the mating hook side facing up. This belt 67 presses the sides of the transparent plate 46 against the sides of the face and chin, preventing the COVID-19 virus from entering the air as an aerosol through the sides of the face or chin. The role of the belt 67 is not limited to the above, but also prevents airborne infection from below and supports the transparent plate under the chin to prevent it from slipping upwards.

[0140] Figure 110 shows the 89th embodiment of the present invention, viewed from behind when the wearer is wearing the present invention. Normally, when a transparent plate is attached to the head 3 using a rubber band 6 or the like, the face transparent plate 46 expands in a curved shape, spreading away from the sides of the face and chin, as indicated by dotted line 461. This creates a large gap between the wearer's sides of the face or chin and the transparent plate 46. In the 88th embodiment of the present invention, belts 67 are provided to narrow the expansion at the bottom of the transparent plate, and as shown in Figure 110, the lower edges of the left and right sides of the transparent plate are pulled by the belts 67. This eliminates gaps between the sides of the face or chin and the sides of the transparent plate 46, thereby preventing the spread of the novel coronavirus in the form of aerosols and airborne infection.

[0141] FIG. 111 is a top view of the 89th embodiment of the present invention, showing the vicinity of the jaw when the present invention is worn. In the 89th embodiment of the present invention, the transparent plate 46 is curved and has a widened lower edge on the side as shown by the dotted line 461, and the belt 67 is attached to the bottom of the transparent plate or its vicinity. This eliminates gaps between the transparent plate and the wearer's face, cheeks, and chin, thereby preventing coronavirus infection. The belt 67 has a Velcro 8 that can be attached at a different position, so that the length of the belt can be adjusted to fit the size of the face.

[0142] The 89th embodiment of the present invention has the effect of narrowing the lateral extent of the transparent plate to prevent aerosol airborne infection of viruses such as the new coronavirus from the sides of the face. In addition to the effect of providing horizontal protection against aerosol airborne infection of viruses such as the new coronavirus from below with the belt portion, there are many other effects, such as the belt acting as a chin rest to more securely fix the transparent plate 46 to the face.

[0143] This is a 90th embodiment of the present invention, characterized in that the jaw belt 67 in FIG. 108, for example, is wide. The material of belt 67 may be plastic, vinyl, nylon, nonwoven fabric, filter material, etc., and the size of belt 67 may be any width, such as 10 to 150 mm. The length of belt 67 may be, for example, 20 mm for the part attached to the transparent plate, 170 mm for the entire length including the attached part, and 50 mm for the hook-and-loop fastener 8 attached to the tip of belt 67. Belt 67 may be any shape, such as rectangular, trapezoidal, semicircular, semi-elliptical, etc., but these dimensions are merely examples and other dimensions may be used. According to the 90th embodiment of the present invention, the cushion can be firmly in contact with the face because it can be pulled from various directions with the belt, and the area of ​​the transparent plate below the belt that is in contact with the outside air can be adjusted as desired, and the strength of the belt is maintained, so the transparent plate can be stabilized and not wobble.

[0144] The 91st embodiment of the present invention is the present invention in which a filter 1067 is provided under the jaw of the lower opening of the curved part of the transparent plate, as shown in Fig. 112. In this case, the filter 1067 also serves as the belt 67, is made of an elastic filter material, and is 150 mm wide, and is an example in which the curved inner opening below the transparent plate is entirely covered with the filter 1067.

[0145] Figure 113 is a front view of the 91st embodiment of the present invention, with Figure 112 expanded. One side of the sector-shaped filter 1067 is adhered to the lower end of the transparent plate 46, and a claw-like protrusion is formed on the arc portion of the sector-shaped filter 1067, which also serves as the belt 67. A hook-and-loop fastener (not shown) is provided on the backside of the arc-shaped protrusion of the sector-shaped filter 1067 to connect the hook-and-loop fastener 8 provided on the lower end of the transparent plate 46 to the claw-like protrusion. In Figure 112, the protrusion is connected to the hook-and-loop fastener 8 at the lower end of the transparent plate, and the filter is positioned below the transparent plate without any gaps. Although Figures 112 and 113 show three hook-and-loop protrusions on the arc portion of the sector-shaped filter 1067 and three connection points with hook-and-loop fasteners 8, the number and locations are not limited. According to the 91st embodiment of the present invention, by placing a filter at the lower end of the transparent plate under the chin, it is possible to prevent inhaling aerosols of viruses such as the new coronavirus when breathing, and the filter does not stick to the mouth.Furthermore, since the filter has a large area, it has the effect of making breathing much easier.

[0146] The 92nd embodiment of the present invention is characterized in that, as shown in Fig. 114, the belt 67 and the subchin filter 1067 are separately provided at the lower end of the transparent plate 46. A hook and loop fastener (Velcro (registered trademark)) 8 is provided on the belt 67 to narrow the lower end of the transparent plate as shown in Fig. 111, and the hook and loop fastener (Velcro (registered trademark)) 8 provided on the subchin filter 1067 and the belt (surface side) pulls and attaches the filter so that it comes into tight contact with the lower opening of the transparent plate without any gaps. By separating the belt and the filter, adjustment of the connection between the belt 67 and the lower end of the transparent plate under the chin and adjustment of the adhesion of the filter 1067 under the entire chin can be performed separately, which has the effect of preventing gaps from occurring between the filter and the transparent plate regardless of the wearer's chin or face shape.

[0147] The 93rd embodiment of the present invention, as shown in Figure 115, is characterized by a horseshoe-shaped sleeve 1010 with a filter 1067 attached, which is removably fitted to the bottom of a transparent plate like a denture, tightly curving the bottom of the transparent plate, with the filter 1067 sealing the lower opening of the transparent plate. When the transparent plate is worn on the head, the bottom end of the transparent plate expands to form a shape 461 that is away from the sides of the face and chin. The sleeve 1010 with the filter 1067 of the present invention is pushed straight into the mouth, like a denture, so that the bottom end of the transparent plate is curved tightly. The force that expands the transparent plate outward and the friction between the horseshoe-shaped sleeve and the transparent plate prevent the sleeve from slipping off the bottom end of the transparent plate or easily coming off the curved transparent plate. The inner curved surface of the sleeve is preferably made of a material such as rubber or adhesive that has a high adhesion to the transparent plate. According to the 93rd embodiment of the present invention, the filter is attached by a sleeve, which makes it easy to replace the filter and also makes it possible to adjust the horseshoe shape to fit the size of the face.

[0148] The 94th embodiment of the present invention is characterized by the provision of a vertical side cushion portion 553 with an inclined end face that can also be used as a chin rest, as shown in Figures 116, 117 and 120, in which the side vertical cushion of the A4 transparent plate 48 is extended to the chin belt 67. 116 shows (A) a front view and (B) a side view, in which a part of the chin belt 67 is adhered to the surface of the side of the transparent plate 48.

In Figures 129 and 131, removable medical PSA double-sided tape 941 is used for attachment, but not only double-sided tape but also single-sided tape may be used, and in the case of a transparent plate, removable PSA tape 94 may also be used.

[0163] The 105th embodiment of the present invention, as shown in Figures 130 and 132, is an invention characterized in that the filter is a nose and mouth sheet 1020, and part of the side of the approximately rectangular shape is joined to form a tray shape, making it removable and replaceable to a transparent plate or face. Figure 130 (1-1) shows a removable medical PSA double-sided tape 941 attached to the upper edge of the nasal-oral sheet 1020, and (1-2) shows a removable medical PSA single-sided tape 942 attached to the upper edge of the nasal-oral sheet 1020. In the case of the removable medical PSA single-sided tape 942, a portion of the tape is attached to the nasal-oral sheet 1020 as shown by the dotted line, and the remaining portion is attached to a transparent plate or the base of the nose on the face. In (1-1) or (1-2), the sheet is folded upward from the dotted line, and portions of both sides of the sheet (dotted lines) are joined, for example, by heat sealing, as shown in (2), forming a saucer shape as shown in (3). (3) shows a perspective view of the sheet when slightly curved, as seen from the wearer's side indicated by the arrow. N95 filters and saucer- or bowl-shaped filters should be attachable, detachable, or openable.

[0164] Figure 132 shows the 105th embodiment of the present invention being worn, (A) is a diagram of the present invention attached to the lower end of a transparent plate provided with vertical side cushions 55, for example, (B) is a diagram of the present invention attached to a transparent plate 4 provided with a chin belt 671 that narrows the curvature, (C) is a diagram of the present invention attached to the base of the nose on the head and face with removable medical PSA double-sided tape 941, and (D) is a diagram of (C) viewed from the side. N95 filters and saucer-shaped or bowl-shaped filters should be attachable, detachable, or openable.

[0165] In the 104th and 105th embodiments of the present invention, the length of the tape for attaching to the transparent plate or face may be the length across the entire upper edge of the nose and mouth sheet 1020, and when attaching to the face in particular, it may be about 10 mm wide, for example, at two points on the left and right sides of the base of the nose. According to the 104th and 105th embodiments of the present invention, a bag-shaped (bowl-shaped) or dish-shaped sheet is attached in a removable and replaceable manner, which has the effect of making it possible to provide an inexpensive and always clean filter. Furthermore, when attached to the face, the present invention has a flat and compact shape, which has the effect of making it very convenient to carry and easy to put on.

[0166] The 106th embodiment of the present invention is characterized in that, as shown in Figures 132 and 133, a bib-like sheet (made of a material such as a vinyl sheet, cloth, nonwoven fabric, or N95 filter) 1000 is provided at the lower end of a transparent plate 4, and neck belts 672 are attached to both ends of the bib-like sheet 1000. Figure 133 is a front view showing the bib-like sheet 1000, which has an inverted ladder shape and is adhered to the lower end of the transparent plate 4. The upper part of both sides of the sheet is provided with neck straps 672 for wrapping the sheet around the neck in the horizontal direction.

[0167] FIG. 134 is a rear view of the 106th embodiment of the present invention, in which a cushion is provided also at the upper end of the bib-like sheet 1000, thereby eliminating gaps on the sides of the chin. When wearing the present invention, the bib-like sheet 1000 is fixed to the head with the rubber band 6, and the neck belts 672 at both ends of the bib-like sheet 1000 are narrowed below the transparent plate 4 behind the neck, and the hook-and-loop fasteners 8 of the neck belts 672 are fastened while pulling backward so that there is no gap between the cushion parts 59, 55 and the cushion at the top of the bib sheet and the face. According to the 106th embodiment of the present invention, the lower part of the transparent plate 4 is narrowed behind the neck without using a chin belt, which makes it easy to fasten and makes it easier to talk without a chin belt. The bib-like sheet 1000 also has the effect of replacing a cold weather scarf. The bib-like sheet 1000 eliminates any gaps between the transparent plate and the face, which has the effect of preventing the entry of viruses such as the new coronavirus while still allowing for easy breathing.

[0168] The 107th embodiment of the present invention is characterized in that, as shown in Figures 135 and 136, a window is provided in part of a bib-like sheet (made of a material such as a vinyl sheet, cloth, nonwoven fabric, or N95 filter) 1000 attached to the lower end of a transparent plate 4, and an N95 filter 1095 is attached to it. Figure 135 shows an N95 filter 1095 attached near the center of the bib-like sheet 1000 of Figure 133. The N95 filter 1095 is positioned so that it is in the space under the chin when the present invention is worn. Since N95 filters are expensive, they can be arbitrarily small, but it is also possible to use an N95 filter for the entire bib-like sheet. The N95 filter can be attached using known methods such as gluing or sewing. FIG. 136 is a rear view of FIG. According to the 107th embodiment of the present invention, an N95 filter is provided, so even if the material of the bib-shaped sheet is made of an impermeable material such as a vinyl sheet, it is not difficult to breathe and can also prevent viruses.

[0169] The 108th embodiment of the present invention is characterized in that, as shown in FIG. 137, an N95 bag-shaped filter 1095 is provided at the lower end of the transparent plate 4 and covers the area around the chin in a bowl shape. Figure 137 shows the method of forming and structure of the bag-shaped N95 filter 1095 that is attached to the lower end of a transparent plate that is narrowed downward when worn. (1) is an overall view of the invention when unfolded, and for example, the chin belt 67 is a diagram using the chin belt 67 of the 94th embodiment. The size of the transparent plate is B5 or A4, horizontally. One side of the approximately ladder-shaped N95 filter 1095 is adhered to the transparent plate 4 with, for example, double-sided tape 66. (2) is a diagram of an N95 filter 1095 showing its unfolded size, where a is the shortest distance when bent, b is the width of the transparent plate, and c is the direction in which the N95 filter is bent. (3) is a diagram of (2) bent in the direction of c along the dotted line with heat seals 92 applied to both ends. (4) is a perspective view of (3) in which the difference in length between a and b has resulted in a bag-like shape with an opening 93 at the top. The part indicated by the "x" surrounded by the end of the N95 filter indicates the opening 93 of the bag made from N95. (5) shows a front view when attached, and (6) shows a cross-sectional view. One side of the N95 bag-shaped filter 1095 is adhered to the surface of the transparent plate, and the opposite side is adhered to the underside of the attached chin belt 67 with, for example, double-sided tape 66. The size of the N95 bag-shaped filter 1095 is an inverted trapezoid shape in Figure 137, but the shape can be determined arbitrarily so that when the lower end of the transparent plate is narrowed and curved, the shortest distance a when curved and the size are equal to or greater than the width b of the transparent plate. According to the 108th embodiment of the present invention, by covering the filter with a bag-like (bowl-shaped) filter, it is possible to maximize the prevention of airborne infection and intrusion of aerosols of viruses such as the new coronavirus, and the large surface area has the effect of making breathing less difficult.

[0170] The 109th embodiment of the present invention is an invention characterized in that a transparent plate 481 divided horizontally into two is joined with a connector 49 such as a transparent adhesive tape made of polyester or the like, as shown in Figures 138 and 139. The transparent plate, which is oriented horizontally and measures B5 or A4 in size before division, is divided into two halves, top and bottom. As shown in Figure 139, when not in use, it can be folded so that the side on which viruses such as the new coronavirus are attached is on the inside (so that the cushion 59 is on the outside). According to the 109th embodiment of the present invention, the contaminated surface of the transparent plate can be folded inward, which makes it easy to carry and has the effect of preventing secondary contamination.

[0171] The 110th embodiment of the present invention is an invention characterized in that, as shown in Figures 140 and 141, a transparent plate 482 is divided into two parts vertically and horizontally, and the whole is divided into four parts, which are joined together with a transparent connector 49 such as a transparent adhesive tape made of polyester or the like. As shown in Figure 140, connectors 49 are attached to the outside of the divided transparent plate 482 (the outside of the transparent plate when worn) in the horizontal direction, extending to the left and right ends of the transparent plate, and connectors 49 separated by horizontal connectors 49 are attached in the vertical direction. When worn, the position of the eyes is higher than the connectors that cross horizontally, so connectors 49 do not obstruct the field of vision. As shown in FIG. 141, the present invention is folded horizontally and then vertically. In Figure 141, for ease of understanding, the connectors are shown as long and with gaps between the transparent plates 482, but because the transparent plates 482 are flexible, each transparent plate 482 is connected by the connectors without any gaps, allowing it to be folded vertically and horizontally. According to the 110th embodiment of the present invention, the size is, for example, 1 / 4 of A4 size when carried, making it convenient to carry around. In addition, there is an advantage that the connector 49 is not positioned at the eye level when worn, so it does not obstruct the field of view.

[0172] The 111th embodiment of the present invention is an invention characterized in that a transparent plate 483 divided into two vertically and three horizontally is connected with a transparent connector 49 such as a transparent adhesive tape made of polyester or the like, as shown in Figures 142 and 143. As shown in Figure 143, fold it in half horizontally, then fold it twice vertically. According to the 111th embodiment of the present invention, when carried, the size is, for example, 1 / 6 of A4 size, so that it is very small and can be carried around with ease.

[0173] The 112th embodiment of the present invention is characterized in that, as shown in Figures 144 and 145, transparent plates 484 divided vertically into four are connected with connectors 49 such as transparent adhesive tape made of polyester or the like. Each transparent plate 484 has rounded corners. The R of the corners is an arc with a radius of 1 mm to 6 mm. The size of the entire transparent plate of the present invention is, for example, A4, and four transparent plates 484 are connected, but the size of the entire transparent plate may be B5 or other sizes. Forehead cushion portions 595 are provided on each of the two central transparent plates 484, and rubber bands 6 for fixing to the head are provided on the upper ends of the two outer transparent plates 484.

[0174] 145 shows the folding sequence for the 112th embodiment of the present invention. The present invention is in an unfolded state (A), and the two outer transparent plates 484 are folded so that the cushion portions 595 face outward (B), and the rubber band 6 is also folded at the same time (C), and then the two central transparent plates 484 are also folded so that the cushion portions 595 face outward (D). 144 and 145 are vertically divided into four parts, but the scope of the present invention also includes folding the bag vertically into two, three or five parts. According to the 112th embodiment of the present invention, for example, if the entire device is A4 size, the width will be approximately 74 mm, which has the advantageous effect of being able to fold it to a size that can be inserted into a breast pocket. In addition, all corners of the transparent plate 484 are rounded, which has the effect of preventing injury from the corners and making it safe.

[0175] The 113th embodiment of the present invention, as shown in Figures 146 and 147, is characterized in that a transparent plate 484 is divided vertically into four sections, the head fixing device is a folded plastic band 68, and a triangular small cushion 596 is provided in the forehead contact portion. The forehead cushion portion 595 is provided only on the two central transparent plates 484, and furthermore, small triangular cushions 596 are provided on the two outer transparent plates 484 so as to contact the ends of the central cushions 595, so that when the present invention is worn on the forehead, there is no gap between the head and the transparent plates when viewed from above. The plastic band 68 should be thin, flexible, and strong; it does not have to be elastic; suitable materials are Teflon, vinyl, PE, PP, and PET, and the thickness should be 50 to 300 microns and the width 10 to 30 mm. As shown by the dotted lines in the plastic band 68 in Figure 146, to make it easier to fold, it is bent near the adhesive part with the transparent plate and at about half the length.

[0176] 147 shows the folding sequence for the 113th embodiment of the present invention. (A) The present invention is in an unfolded state, (B) the two outer transparent plates 484 are folded so that the cushion portions 595 face outward, (C) the plastic band 68 is also folded at the same time, and (D) the two central transparent plates 484 are also folded so that the cushion portions 595 face outward. According to the 113th embodiment of the present invention, in addition to the effect that it can be folded and put in a breast pocket, the small right-angled triangular cushion 596 has the effect that the transparent plate can be closely attached to the forehead when worn, and the plastic band 68 can reduce the size when folded, and the plastic band 68 has the effect of being easy to fold because it has a folding tendency.

[0177] The 114th embodiment of the present invention is characterized in that, as shown in FIG. 148, an N95 filter 1095, for example, is provided at the lower end of a transparent plate 484. This makes it foldable for easy portability, and it can be quickly removed and has the effect of preventing viruses from entering the mouth, nose, and eyes with the N95 filter 1095 that covers the part of the transparent plate below the chin.

[0178] The 115th embodiment of the present invention is characterized by a case 261 capable of storing the inventions of Figures 144 to 145, as shown in Figure 149. The opening of the storage case 261 has a belt 262 to which the hook-and-loop fastener 8 of the storage case is adhered, preventing the stored items from falling out. The storage case 261 is made of a flexible material with a thickness of 300 microns or less, such as plastic, Teflon, vinyl, PE, PP, or PET. According to the 115th embodiment of the present invention, there is an advantage that the invention of the 112th embodiment (Figures 144 and 145) can be carried without transferring contamination of viruses such as the new coronavirus to other items.

[0179] The 116th embodiment of the present invention is characterized by a case 261 having a protruding portion 263 that corresponds to the folding of the cushion portion capable of storing the invention of the 113th embodiment (Figures 146 to 147), as shown in Figure 150. In Figure 150, e is the expanded width of the protruding portion, and d is the depth of the protruding portion. The opening of the storage case 261 has a protruding portion 263 with a depth e of about 40 mm and an opening width d of about 10 mm, to match the cushion's depth of about 30 mm. In the 113th embodiment (Figs. 146 and 147), a triangular small cushion 596 is provided at the forehead contact portion, so the upper portion of the folded transparent plate 484 is partially thick. Therefore, if the device is placed in the storage case of the 115th embodiment (Fig. 149), the opening may be torn. However, according to the 116th embodiment of the present invention, there is an advantage that the invention of the 113th embodiment (Figures 146 and 147), in which the thickness of the cushion part becomes thicker when folded, can be easily carried without the case being torn, without the contamination of viruses such as the new coronavirus being transferred to other objects.

[0180] 151, the 117th embodiment of the present invention is an invention characterized in that the cushion portion is provided with a thick cushion portion 593 with both ends inclined, and a recess 5931 is provided in the cushion portion to accommodate the portion of the lens of a scope or the like that protrudes forward from the forehead. This invention is suitable for use when using a dental scope or for anesthesiology, etc., and the entire cushion is thick and has a recess cutout so that the portion of the scope and spectacles located at the base of the nose do not interfere with wearing the invention. The thickness of the thick cushion portion 593 is, for example, 40 mm, and can be set arbitrarily between 10 and 60 mm to match the thickness of the glasses or scope adjustment portion. The width of the thick cushion is, for example, 30 mm, and a width of 20 to 40 mm is provided to stabilize the product of the present invention attached to the head so that it does not wobble. Polyurethane foam is preferable as the cushion material, but a surface treatment can be applied to reduce dust generation, or a gel-like substance can be used. The size of the transparent board is A4 or B5 landscape orientation. The recess 5931 is not cut out to both ends of the cushion to ensure strength. The step of the recess 5931 is set to a level that does not interfere with the scope or glasses. According to the 117th embodiment of the present invention, by providing a recess in the thick cushion, the present invention can be attached correctly to the head, and the transparent plate can be attached perpendicular to the face, which has the effect of preventing blurring or distortion of the field of view. In addition, since the scope or glasses do not get in the way, the present invention can be worn stably without wobbling.

[0181] The 118th embodiment of the present invention is characterized in that a sheet 1030 such as a cooling water-absorbing sheet is provided on the thick cushion portion 593 as shown in FIG. (A) is a rear view (hereafter, to clarify the distinction between the drawings, an x ​​symbol within a circle indicates the direction in which the present invention is viewed from the wearer's side, indicating that it is a rear view of the present invention), (B) is a top (plan) view, and (C) is a side cross-sectional view. A cooling water-absorbent sheet 1030 is attached to the top and side surfaces of the thick forehead support cushion 593, excluding the inclined portion of the cushion with an inclined end. In this case, the cooling water-absorbent sheet 1030 does not need to be joined or fastened to the cushion. This is because, when worn, the cooling water-absorbent sheet 1030 is sandwiched between the cushion 593 and the wearer's forehead, so it will not fall off. However, for safety, hook-and-loop fasteners 8 may be attached in multiple locations on the top of the cushion 593 (for example, two locations on the left and right ends), as shown in the cross-section of (C). The hook and loop fastener 8 is, for example, a hook-shaped hook and loop fastener (male) attached to the surface of the cushion with double-sided adhesive tape, and the hook and loop fastener (male) 8 is directly joined to the cooling water absorbent sheet or other sheet 1030. If the surface of the cooling water absorbent sheet is too smooth, it will not bond, so in that case a loop-shaped hook and loop fastener (female) is also attached to the cooling water absorbent sheet. Cooling absorbent sheets are made of fibers such as nylon, and are cool to the touch when they come into contact with the skin, providing a cool, comfortable feel. They also have a breathable structure that quickly absorbs and diffuses sweat, allowing it to evaporate, making them comfortable against the skin. As shown by the dotted lines in (A) and (C), a recess 5931 for a lens such as a scope may be provided, as in the 117th embodiment. The present invention is suitable for use when working in an anesthesiology department, for example. In addition, in the present invention, when a recess 5931 for a lens such as a scope is provided, it is preferable to wear it during dental work, for example. The 118th embodiment of the present invention has the effect of preventing viruses such as the new coronavirus while enabling dentists, anesthesiologists, etc. to work efficiently. In other words, even if you sweat while wearing it, the cooling absorbent sheet absorbs the water and provides a cool feeling to the touch, allowing you to work comfortably. In addition, since the cooling absorbent sheet is removable, it can be easily cleaned and the cushion part will not be damaged.

[0182] The present invention is a 119th embodiment, characterized in that a cooling, water-absorbing sheet or the like 1030 is provided on the entire side of the thick cushion part 593 that comes into contact with the head, as shown in Figure 153, (A) back view, (B) top view, and (C) side cross-sectional view. The cooling sheet 1030, such as a water-absorbing cooling sheet, is provided only on the sides of the thick cushion portion 593, and both ends of the cooling sheet 1030 face hook-shaped hook-and-loop fasteners 8 (male) attached with double-sided adhesive to the inclined portion of the cushion portion, joining the cooling sheet 1030 to the thick cushion 593. The hook-and-loop fasteners prevent the cooling sheet from falling off the cushion. When worn, the present invention allows the cooling sheet to come into contact with not only the forehead but also the sides of the head. The cooling sheet 1030 is, for example, an A4 landscape sized transparent plate, approximately 30 mm wide and 300 mm long, and is replaceable. In Figure 153, only two hook-shaped hook-and-loop fasteners 8 (male) are provided on the cushion, and no hook-and-loop fasteners are provided on the cooling sheet 1030, but loop-shaped hook-and-loop fasteners 8 (female) may be provided depending on the surface condition of the cooling sheet 1030. The hook-and-loop fasteners 8 are circular or semicircular with a diameter of about 20 mm, and may be installed in three or more places. If the cooling sheet 1030 and the cushion are connected and fixed at only two places on both ends of the cooling absorbent sheet or the like 1030 as described above, the cooling sheet 1030 may sag if the transparent plate is bent, and if multiple hook-and-loop fasteners are used to fasten the present invention, it will feel uncomfortable against the skin when worn. Therefore, it is preferable to install hook-and-loop fasteners 8 in four or fewer places. As shown by dotted lines in (A), (B), and (C), the present invention may also be provided with a recess 5931 for a lens such as a scope, as in the 117th embodiment. The present invention is suitable for use when working in an anesthesiology department, for example. Furthermore, when the present invention is provided with a recess 5931 for a lens such as a scope, it is preferable to wear it during dental work, for example. According to the 119th embodiment of the present invention, when the present invention is worn, the cooling absorbent sheet 1030 is applied not only to the forehead but also to the sides of the head of the wearer, so that it is possible to absorb sweat over a wide area and provide a cooling effect. In addition, since all parts of the cooling absorbent sheet are in contact with the head, the sheet is highly efficiently utilized, and it is cost-effective.

[0183] The 120th embodiment of the present invention is an invention characterized in that, as shown in FIG. 154, only a cooling water-absorbing sheet 1030 that comes into contact with the head is provided on a transparent plate, i.e., there is no head support cushion portion. (A) is a rear view, (B) a top (plan) view, and (C) a side view. Rubber bands 6 with hook-and-loop fasteners 8 for fastening to the wearer's head are fixed to the upper ends of both sides of the transparent plate 4, and circular hook-and-loop fasteners 8 (male) are adhered to the inside of the transparent plate, further to the ends of the rubber bands. A cooling, water-absorbing sheet 1030 is provided on top of the transparent plate so as to cover the ends of the rubber bands fixed to the upper ends of both sides of the transparent plate 4. The cooling, water-absorbing sheet 1030 is joined to the hook-and-loop fasteners 8 (male) adhered to the transparent plate, so it will not come off when worn. In FIG. 154, there are two hook-and-loop fasteners 8 (male) adhered to the transparent plate, but multiple fasteners may be provided depending on the bending (sagging) state of the cooling water absorbent sheet or other sheet 1030. In addition, the width of the cooling water absorption sheet etc. 1030 is 10 to 50 mm. However, it is preferable that the width be approximately the same as that of the rubber band. The thickness of the cooling water absorbent sheet or the like 1030 is set to 0.2 to 5 mm, but in the present invention where there is no contact cushion for the forehead, etc., it is preferable that it is 1 mm or more. The present invention is suitable for use in, for example, otolaryngology. After the present invention is attached to the head, a concave mirror can be attached to the head and the transparent plate of the present invention, allowing for hygienic work. Furthermore, in the present invention, when the nose comes into contact with the transparent plate, a non-foamed cushioning material or the like that comes into contact with the nose may be provided approximately in the center of the transparent plate. According to the 120th embodiment of the present invention, there is an advantage that it is clean because it does not have a foam cushion. It also has the advantage of absorbing sweat and providing a cooling sensation. Furthermore, even when a large-sized attachment such as a concave mirror needs to be worn on the head, there is an excellent advantage that the large attachment can be worn after wearing the present invention.

[0184] The 121st embodiment of the present invention is characterized in that a thick nose cushion 501 is provided at the approximate center of a transparent plate recessed into a V shape or the like, as shown in FIG. (A) is a rear view, (B) a top (plan) view, and (C) a side view. The 87th embodiment is a mask in which a transparent plate covering the entire face is held in place by nose pads. In the present invention, a thick cushion 501 with a groove conforming to the shape of the nose and an inclined cushion edge (e.g., a 15-degree slope) is provided in the center of a horizontally placed transparent plate 4, for example, of A4 size, in order to fit the mask around the base of the nose. The thickness of the thick cushion 501 is, for example, 40 mm, and can be set arbitrarily between 10 and 60 mm so as not to come into contact with the forehead, but a thickness of 20 mm or more is preferable. The width of the cushion is 20 to 40 mm, which allows for stable attachment when worn around the nose. As shown by the dotted line in the center of the thick nose cushion 501 in Figure 155, the groove formed in the thick nose cushion 501 to fit the shape of the nose is wider and deeper at the bottom than at the top, so that it fits the shape of the base of the nose and evens out the pressure that the cushion presses against the face. However, a simple V-shaped groove may also be formed. To wear the mask of the present invention, the left and right sides of the transparent plate are pulled with the rubber bands 6 with hook-and-loop fasteners 8, and the transparent plate is brought into tight contact with the cushion from the nose to the cheeks, and then attached and fixed to the head. The rubber band may be a string (including temples) as in the tenth embodiment, and the material of the nose pad cushion with a V-shaped recess or the like can be selected arbitrarily. According to the 121st embodiment of the present invention, the nose, mouth, and eyes are separated and blocked by cushions above and below, so inhaled air is also blocked and does not enter the eyes. Also, the air in the gap between the upper transparent plate and the face is warmed by the heat of the face and flows upward, making it difficult for outside air to enter the gap between the upper transparent plate and the face. Furthermore, the heat of exhaled air in the gap between the lower transparent plate and the face has the effect of preventing the entry of viruses such as coronavirus.

[0185] The 122nd embodiment of the present invention is an invention characterized by the fact that a transparent plate 401 folded in two is worn while being pushed open, as shown in Figure 156, where (A) is a rear view, (B) is a top view, and (C) is a side view, and (A), (B), and (C) are unfolded views of the transparent plate 401 that is folded along the dotted line in the center of the transparent plate, and a bib-shaped sheet 1000 is attached to the bottom end of the transparent plate. (D) is a schematic diagram (top view) showing the transparent plate being pushed open in order to wear it, and (E) is a schematic diagram (top view) of the present invention worn on the face, and the bib-shaped sheet 1000, cushion, etc. are omitted from (D) and (E). The present invention is characterized by the provision of thick nose pad cushion 501, rubber belt 6, bib-shaped sheet 1000, etc., and by folding the transparent plate in half along the dotted line in the center as shown in (D), and plastically deforming the transparent plate so that when opened in the direction of the arrow in (D), a restoring force acts in the bent direction. (E) is a schematic diagram showing how the face of head 3 is sandwiched between transparent plate 401 by the restoring force in the bent direction. The thick nose pad cushion 501 of the present invention has a large slit in the center so as not to hinder the folding of the transparent plate. The thickness is also adjusted depending on the restoring force of the transparent plate. If the restoring force of the transparent plate pressing against the sides of the face is strong, the rubber band 6 may not be provided and a rubber band or the like may be used instead. (It is worn like a mask, so to speak.) According to the 122nd embodiment of the present invention, the mask is designed to be worn in an unfolded position, so there is no need to feel like your head is being tightened by a rubber band, etc. Also, the gap between the face and the transparent plate can be reduced, which has the effect of preventing outside air from entering, and furthermore, since the bib-like sheet 1000 is provided, the area under the chin is also sealed with a filter, which has the effect of preventing viruses such as coronavirus.

[0186] The 123rd embodiment of the present invention, as shown in Figure 157, is an invention in which the transparent plate at the position of the mouth when worn can be opened and closed, and transparent plate doors 402 with openable portions are provided on the two central transparent plates of the transparent plate 484 divided vertically into four, (A) is a front view and (B) is a back view. The present invention is characterized by the provision of an opening and a lid at the bottom of the transparent plate, and the lid can be opened and closed vertically or horizontally, allowing food to be inserted through this opening and eaten safely under the coronavirus. For example, in FIG. 156, an openable door 4021 is provided on a transparent plate so as to open like a double door, and is fixed in place by hook and loop fasteners 8 when opened or closed.

[0187] The 124th embodiment of the present invention, as shown in Figure 158, is an invention in which a double-door lid 4021 is attached to a single transparent plate having an opening in the lower center. The size of the openable door 4021 is set so that the opening in the transparent plate 402 and the openable door 4021 partially overlap. This eliminates gaps from the front, preventing droplets of coronavirus and the like from spreading. In addition, removable PSA tape 94 is attached to the edge of the openable door 4021 and the edge of the transparent plate 402. By using the removable PSA tape 94, the open / closed door can be easily attached and detached with little force.

[0188] The 125th embodiment of the present invention is another embodiment of the present invention in which, as shown in Figure 159, an openable door is provided on the transparent plate at the position of the mouth when the device is worn, allowing food to be ingested. Example (A) is characterized by folding the lower part of the transparent plate 402 upward. When the transparent plate is thick (for example, 300 microns or more), it is removed and the transparent plate 4 is flattened, and then the lower part of the transparent plate 402 is folded outward and upward along the solid line so that the dotted line is at the bottom edge of the transparent plate. The transparent plate is then curved again and attached. When the transparent plate is thin (for example, 100 microns or less), the transparent plate deforms slightly, so the lower part of the transparent plate can be lifted as is. Because the transparent plate is curved, the folded part is fixed to the main body of the transparent plate. This allows for eating, etc. The transparent plate 4 is connected to the other transparent plate portions by a connector 49 such as a transparent adhesive tape made of polyester or the like. According to the present invention (A), the structure is simple, and the lower part of the folded transparent plate is fixed and opened, so it can be manufactured at low cost. In addition, the side of the transparent plate also opens when worn, making it easier to eat. The present invention (B) is characterized in that a door 402 having an openable portion is provided on one of the central transparent plates divided vertically into three. The openable portion is fixed with a hook and loop fastener 8 or the like. The present invention (C) is an invention in which an openable door 402 is provided at the bottom center of a single transparent plate 4. The openable transparent plate door is fixed with a hook and loop fastener 8 or the like. According to the 123rd, 124th, and 125th embodiments of the present invention, the opening and closing part of the transparent plate is fixed by hook and loop fasteners, double-sided tape, or the effect of curvature, so that it can be easily opened and closed while attached, allowing meals to be eaten.

[0189] The 126th embodiment of the present invention is an invention characterized by the fact that the lid is attached to a transparent plate and can be flipped up, as shown in Figures 160 and 161. By overlapping the transparent plate and the transparent lid, firstly, the flipped up transparent plate does not get in the way of the eyes when flipped up, secondly, the bottom or both ends can be used as handles for flipping up whether you are left-handed or right-handed, and thirdly, it has the effect of sealing the gap between the main body and the door. As shown in FIGS. 160(A), (B), FIGS. 161(A), (B), if the width and height dimensions of the opening 4023 of the transparent plate 402 are l and h respectively, and the width and height dimensions of the transparent lid 4021 are L and H respectively, then l < L and h < H. L is made longer than the length from one end to the other end of both eyes during wearing. l and h are opened to a length that allows food to pass through sufficiently. The transparent plate 402 and the lid 4021 are overlapped on the vertical side surface of the transparent plate opening 4023 by a length of (L - l) / 2. Also, the upper surface of the transparent plate opening 4023 overlaps with the lid 4021 by (H - h) / 2, and they are joined by a transparent plate connector 4024 such as a transparent PSA tape to the transparent plate 402. The lower end of the lid 4021 protrudes downward by a length of (H - h) / 2 from the lower end of the transparent plate to form a handle. The overlap of the transparent plate 402 and the lid 4021 on the vertical side surface of the transparent plate opening 4023 is preferably such that there is no gap when the lid is closed, and it is about 2 mm to 20 mm, but it is preferably overlapped by about 10 mm. The protruding length of the lower end of the lid 4021 from the lower end of the transparent plate should be about 0 to 20 mm so that it can be easily lifted by hand at the lower end or both ends of the transparent lid. If it protrudes too much, it will be in the way, so it is preferably about 10 to 5 mm. As shown in FIG. 160(B), in the 126th embodiment where a transparent lid is provided on three horizontally connected elongated transparent plates 402, it can be folded, put into a pocket and carried, and taken out during meals for instant use. As shown in FIG. 160(C), when the lower end of the lid 4021 is held as a handle during wearing and the lid 2021 is rotated around the connector 4024 such as a transparent PSA tape indicated by the dotted line in the direction of the arrow, since the transparent plate 402 is curved along the face, the lid 4021 is deformed as it bounces up. When it rotates to the upper part where the transparent plate and the transparent lid overlap, the lid does not rotate and fall downward, and the transparent plate 402 and the lid 4021 are integrated and fixed in the raised state, so the opening is maintained. 161(C), the transparent lid may be made in any shape, such as semicircular. The reason for this is that the length of the transparent plate connector 4024 can be shortened, making it easier to raise and lower the lid 4021. According to the 124th embodiment of the present invention, an advantage is that while a normal mask requires the wearer to take it off and put it back on every time they put food in their mouth, the mask of the present invention can be opened and closed instantly with one hand from either the left or right side, making it possible to eat safely during the COVID-19 pandemic.

[0190] The 127th embodiment of the present invention is characterized by the provision of a rotatable transparent plate door 4026 with a fulcrum on the head fixing rubber band 6 at the bottom of a transparent plate 402 having an opening and closing portion long enough not to cover the mouth, as shown in Fig. 162. The transparent plate 402 and the transparent plate door 4026 below it partially overlap, preventing splashes from the front. Furthermore, when the present invention is worn, the rotatable fulcrum of the transparent plate door 4026 becomes the side of the wearer, and when eating, the transparent plate door 4026 can be flipped up, allowing food to be brought to the mouth.

[0191] The 128th embodiment of the present invention, as shown in Figure 163, is an invention characterized by opening and closing the lower part of the transparent plate by sliding the transparent plate door. In (A), a sliding transparent door 4027 with a groove is connected to a transparent plate 402 having an opening and closing portion with pins 4028 on the left and right sides, with small holes at both ends of the groove to stop the sliding, so that the transparent door 4027 can be slid upward to insert food into the mouth when eating. In (B), the transparent door 4027 is connected to a transparent plate 402 having a groove in a locking shape with a pin 4028, so that the transparent door 4027 can be slid to insert food into the mouth when eating. For example, as shown in Figure 163, grooves are formed on the sides in an inverted J shape when attached, so that the transparent door 4027 can bend when slid up and not fall.

[0192] The 129th embodiment of the present invention is for use with a conventional mask. As shown in the front view of Figure 164(A), the size of the transparent plate 485 is shorter than the B5 or A4 size used in other embodiments, e.g., a vertical length of approximately 105 mm and a horizontal length of approximately 297 mm. The width of the belt is approximately 25 mm. As shown in the top view of Figure 164(B), the thickness of the cushion 594 is approximately 20 to 40 mm, with both ends inclined at an angle of, e.g., 45 degrees. Figure 164(C) is a front view of a conventional mask 1, 2 and the present invention 485, 594 worn by a person 3. By using a cushion 594 that is thicker than usual, e.g., approximately 40 mm, the mask will not fog up when used with a conventional mask and will also allow the use of glasses. The 129th embodiment of the present invention has the effect of preventing the entry of viruses such as the novel coronavirus through the eyes, which are not covered by conventional masks. Furthermore, while conventional face shields make it impossible to eat or drink, this embodiment has the effect of making it possible. Furthermore, while conventional masks and face shields cause the face to heat up, the embodiment of the present invention has the effect of preventing the face from getting hot. Furthermore, conventional face shields tend to hit the shoulders or clothing when turning the neck (face) or looking down, causing them to slip or come off. However, this embodiment does not hit the body even when the neck is bent at a large angle or when looking down, so it does not slip or come off. Furthermore, it is half the size and half the weight of conventional face shields, making it compact and easy to carry.

[0193] As shown in Figure 165, the 130th embodiment of the present invention is a transparent plate 4 provided with a head support cushion 59, a vertical side cushion portion 553 that also serves as a chin support, a vertical side cushion portion 55, and a lower cushion portion 58, which is joined at a position, for example, 1 / 3 from the bottom of the transparent plate 4, and is separated into two pieces at a position, for example, 1 / 3 from the bottom, and the two separated pieces can be freely rotated as shown by the arrows in the figure using a connector 49. To use this embodiment, when eating or drinking, remove the present invention from your face, fold the lower part of the transparent plate 4, for example, about 1 / 3 of it, as shown by the arrow, and overlap it with 1 / 2 of the upper 2 / 3 of it. When you then put this embodiment on your face, the transparent plate 4 and the folded 1 / 3 of it will bend, and the 1 / 3 of it will be fixed while overlapping the 2 / 3 of it. The vertical side cushion portion 55 and the vertical side cushion portion 553 that also serves as a chin rest have a slit 511 in the cushion at the separation position of the transparent plate 4 so that the cushion does not get in the way of folding back. When wearing the present invention, the lower part of the transparent plate 4 is narrowed by the chin belt 67, but only when eating is the lower part of the transparent plate 4 partially opened according to the procedure of the present invention to take food or drink.

[0194] Similar to FIG. 165, the 131st embodiment of the present invention is such that the rubber band 6 of the 130th embodiment is positioned not at the top of the transparent plate 4 but at approximately the center of the transparent plate 4, as shown in FIG. A thick nose cushion 501, a head cushion 59, a vertical side cushion part 553 also used as a chin cushion, a vertical side cushion part 55, and a lower cushion part 58 are provided on the transparent plate 4, and are separated into two pieces, for example, at the bottom 1 / 3, and the two separated pieces can be freely rotated as shown by the arrows in the figure using a connector 49. The thick nose cushion 501 is provided with a nose-shaped recess 512 that fits the shape of the nose, and when worn, it fits tightly to the face without any gaps. The thick nose cushion 501 is 20 to 40 mm thick, while the head cushion 59, vertical side cushions 55, vertical side cushions 553 that also serve as a chin rest, and lower cushion 58 are 10 to 30 mm thick. This allows the thick nose cushion 501 to fit snugly against the nose when the mask is worn by a person 3 using the rubber band 6, separating the eyes, nose, and mouth. The head cushion 59, vertical side cushions 55, and vertical side cushions 553 that also serve as a chin rest contact the face, blocking outside air. The lower cushion 58 and chin strap 67 also eliminate gaps between the face and the transparent plate around the cheeks and chin.

[0195] According to the 130th and 131st embodiments of the present invention, the transparent plate 4 has no gaps on the face and can block outside air, which has the effect of preventing viruses from entering through the eyes and nose when eating or drinking. Furthermore, according to the 127th embodiment, the nose pad thick cushion separates the nose, mouth, and eyes from the transparent plate and the facial space, which has the effect of preventing the transparent plate in the eye area from fogging up due to exhaled breath.

[0196] 167, is an invention characterized in that ear loops and strings are provided on, for example, a known mask 1 as a breathing portion covering the nose and mouth with nonwoven fabric or cloth, and a transparent film body 404 having a thickness of about 100 microns or 75 microns is attached integrally to the mask, and for example, a cushion-cum-adhesive part 944 is used to adhesively fix the inside of the transparent film body 404, the cushion 502, and the known mask 1. Fig. 167(A) is a front development view of the known mask 1 adhesively fixed to the invention of Fig. 168(A), Fig. 167(D) is a front development view of the known mask 1 adhesively fixed to the invention of Fig. 168(D), and (F) is a front development view of the known mask 1 adhesively fixed to the invention of Fig. 168(F). The method of joining and fixing is not limited to the adhesive bonding method used in this embodiment, but the transparent plate 404, cushion 502 and known mask 1 may be joined and fixed to one piece by welding, sewing, adhesive or the like. According to the 132nd embodiment of the present invention, since it is an integrated type, it can protect the eyes at the same time as wearing a conventional mask, and it is foldable and easy to store.

[0197] The 133rd embodiment of the present invention, as shown in FIG. 168, is characterized by a transparent film body 403 having a nose cushion portion 502 at the lower end thereof, which can be detachably attached to the mask 1, and is attached to the head 3 by the rubber bands 2 of the mask 1, etc., and worn on the face. 168(A), (B), and (C), nose pad cushions 502 for contacting and supporting the wearer's nose are adhered with adhesive 52 to the film surface of transparent film body 403, which is a horizontally long rectangular film approximately 100 microns or 75 microns thick, that will be on the inside when worn, and removable adhesive portion 943 is adhered to the film surface of transparent film body 403 that will be on the outside when worn. As shown in (B), removable adhesive portion 943 adhered to transparent film body 403 is composed of permanent PSA tape 9431, carrier 9432, removable or permanent PSA tape 9433, and release liner 9434. As shown in (C), nose pad cushions 502 and removable adhesive portion 943 are provided from the left end to the right end of transparent film body 403. In the 133rd embodiment, the removable adhesive portion 943 uses a removable PSA tape 9433, while in the 132nd embodiment, the removable adhesive portion 943 is bonded and fixed using a permanent PSA tape 9433. Figure 168(D) is a diagram showing another embodiment of the positions of nose pad cushion 502 and removable adhesive part 943 in the 133rd embodiment, in which removable adhesive part 943 is provided at the lower end of the inside of transparent film 403, and nose pad cushion 502 is provided on top of that. Figure 168(E) is a cross-sectional view of Figure 168(D). 168(F) and (G) are a rear view (F) and a side cross-sectional view (G) showing another form of the 133rd embodiment. A nose pad cushion 502 for contacting and supporting the wearer's nose is provided on the inner surface of the transparent film 403, which is a horizontally long rectangular film with a thickness of approximately 100 microns or 75 microns, when worn. The nose pad cushion 502 is attached to the transparent film 403 at a position extending, for example, by approximately half its width from the lower end of the transparent film 403. The cushion-combined adhesive 944, which is used to attach the conventional mask 1, is provided with a release liner 9441, as shown in (G), in the cushion-combined adhesive portion 944, which extends, for example, by approximately half its width from the lower end of the transparent film 403. The cushion-combined adhesive portion 944, like the removable adhesive portion 943, is composed of a permanent PSA tape, a carrier, removable or permanent PSA tape, and a release liner, but these are not shown. In the products of the present invention shown in the 133rd and 132nd embodiments, after peeling off the release liners 9434, 9441, the nose pad cushion 502 and the transparent film 403 are adhered to the upper end of a known mask 1, which serves as a head attachment device covering the mouth and nose, and the mask is attached to the face and head 3 using ear loops 2 or the like. The transparent film 403 according to the 133rd embodiment is a very thin plate with a thickness of 50 to 200 microns, a width of 100 to 210 mm, and a height of 50 to 180 mm, made of a transparent material such as PP or PET. To make it lightweight, the thickness is about 100 microns or 75 microns, and the width is about 170 mm to match the size of a known mask, with a height of about 100 mm, but this is not limited to this. The nose pad cushion 502 is approximately 10 mm wide and 20 mm thick, and its length is either the same as the transparent plate or shorter than that of a known mask 1. The width is 10-30 mm, as it is adjusted to suit the size of the face and nose, fit, comfort, and whether or not the mask is worn with glasses. If the width is too wide, the mask will be heavy and difficult to bend, preventing the mask from fitting tightly to the face and nose. The thickness is 10-40 mm, so that the mask does not come into contact with the eyes or glasses. The thicker the better, but a narrower width can cause slippage and instability when worn, so the mask should be 40 mm or less. The removable adhesive portion 943 and the cushion adhesive portion 944 are double-sided adhesive tape with a width that allows them to be attached to the upper end surface of the mask 1, that does not come off when worn, and that does not obstruct the field of vision when worn, and are 3 to 25 mm wide. A width of approximately 5 to 10 mm is preferable. Furthermore, the transparent film body 403 with the cushion attached and the known mask 1 only need to be detachably connected, and may be connected by, for example, pressing or hooking with hook-and-loop fasteners, tape, clips, etc. Furthermore, a hook-and-loop fastener may not be provided on the known mask, but a hook-and-loop fastener (male) may be provided on the transparent film body. In addition, since the transparent film 403 is placed in front of the eyes, both sides of the transparent film are treated with anti-reflection to make it easier to see, and furthermore, since moisture and exhaled air rise to the top through the gaps in the mask and humidity increases due to body temperature, an anti-fogging treatment is applied to the inside of the transparent film.

[0198] Figures 169 (A-1) and (A-2) of the 133rd and 132nd embodiments of the present invention are front views and side cross-sectional views of the present invention when worn in the form of Figures 167 and 168 (A), in which a known mask 1 is attached to the outer lower end of the transparent film 403 with removable or permanent PSA tape 9433 after peeling off the release liner 9434, and when worn, the nose pad cushion 502 comes into contact with the nose area without any gaps, and the transparent film 403 is positioned in front of the eyes. Figures 169 (D-1) and (D-2) of the 133rd and 132nd embodiments of the present invention are front views and side cross-sectional views of the present invention when attached in the form of Figures 167 and 168 (D), in which the release liner 9434 at the inner lower end of the film transparency 403 is peeled off and then the film transparency 403 is attached by adhering it with a removable or permanent PSA tape 9433. Figures 169 (F-1) and (F-2) of the 133rd and 132nd embodiments of the present invention are a front view and a side cross-sectional view of the present invention when worn in the form of Figures 167 and 168 (F), in which the transparent plate 403, nose pad cushion 502 and the upper end of a known mask 1 are adhered with cushion-cum-adhesive 944 from which the release liner 9441 has been peeled off, and the mask is worn on the head 3. Although FIG. 169 shows the transparent film 403 as the 133rd embodiment, the transparent film 403 in FIG. 169 can be read as the transparent film 404 to make it the 132nd embodiment. The removable or permanent PSA tape 9433 or cushion adhesive 944 is attached to the known mask 1 in a removable manner in Example 133, and in Example 132, it is fixedly bonded, but as mentioned above, the bonding with the known mask is not limited to adhesive. According to the 133rd embodiment of the present invention, the present invention has the advantage that it can be easily attached to, detached from, and replaced with a known mask, making it easy to operate. In addition, according to Examples 132 and 133, by separating the mouth, nose, and eyes with a cushion in contact with the nose, the exhaled air generated upwards with conventional masks is blocked by the cushion and does not enter the eyes, and the transparent plate does not fog up, preventing viruses such as the new coronavirus from entering the eyes from the outside. Furthermore, since the cushion has a recess that matches the shape of the nose, it adheres closely to the nose. Furthermore, using an adhesive that also serves as the cushion has the effect of reducing costs.

[0199] The 134th embodiment of the present invention is characterized in that the nose cushion 502 provided under the transparent film 403 is shaped to fit the shape of the nose and come into contact with the nose without any gaps, as shown in FIG. 170(A) shows a configuration in which a slit 511 is made in the position (almost at the center) of the nose pad cushion 502 that comes into contact with the vicinity of the nose when worn, (B) shows a configuration in which a V-shaped groove that is a nose-shaped depression 512 is provided in the position (almost at the center) of the nose pad cushion 502 that comes into contact with the vicinity of the bridge of the nose when worn, and (C) shows a configuration in which a deep groove that divides the V-shaped cushion into two is provided as a nose-shaped depression 512 in the position (almost at the center) of the nose pad cushion 502 that comes into contact with the vicinity of the bridge of the nose when worn, and furthermore, (D) is a form in which there is a rounded recess and a sloped shape for the nose, (E) is a form in which the cushion is separated into two at the part where the nose touches, (F) is a nose pad cushion 502 form in which the cushion has a rounded sloped shape in form (E), (G) is a nose pad cushion 502 form in form (F) in which the cushion becomes smaller towards the tip of the nose to fit the shape of the nose, and can be in contact with the nose without any gaps. (H) is a form in which the cushion material is a nose pad cushion 515 made of soft fabric such as nonwoven fabric, which feels good against the skin and can prevent roughness of the skin around the nose.

[0200] The 135th embodiment of the present invention is an embodiment of the present invention in which, as shown in FIG. 171, a nose pad cushion part 502 is provided at the lower end of a transparent body 405 whose upper edge is V-shaped and which is worn on the face. In Figure 171(A), when the known mask 1 is worn, the upper end of the known mask is higher in contact with the nose and lower in contact with the cheeks relative to the horizontal plane. The height from the upper end of the known mask to a belt 911, such as that used by medical personnel to secure a scope, is measured (X, Y in the figure), and as shown in Figure 171(B), the V-shaped transparent film 405 is set to have a length X at the end and a length Y at the center, which is the height from the upper end of the V-shaped transparent film 405 to the upper end of the known mask 1. This allows the product of the present invention to be used without coming into contact with the scope even with the scope attached. Specifically, the V-shaped transparent film body 405 is a horizontally long rectangular film approximately 100 microns thick with a V-shaped upper surface, and is attached to the conventional mask using removable or permanent PSA tape. The product of the present invention is attached using the ear loops 2 of the conventional mask 1. The width of the V-shaped transparent film body 405 is the same as that of the conventional mask, and the height is, for example, Y = 55 mm, X = 65 mm, with a difference of about 10 mm being preferable, but both X and Y can be set to 30 to 100 mm depending on the facial shape. In this embodiment, a V-shape is described, but the present invention is not limited to this, and the top edge shape of the transparent film body can be made optimal for the attachment other than that of the present invention. Shapes in which the top edge shape of the transparent film body is non-linear are included in the present invention. Although the nose cushion portion 502 is provided at the lower end of the transparent body 405 in the above description, the present invention also includes a configuration in which there is no nose cushion and the V-shaped film transparent body 405 is directly bonded to the upper end of a known mask. According to the 135th embodiment, even if there is an object such as a scope fixed to the head with a belt or the like, the present invention can be used without coming into contact with the object or blocking the field of view.

[0201] The 136th embodiment of the present invention, as shown in FIG. 172, is an embodiment in which a nose pad cushion portion is partially provided on the inside of the lower end of the transparent film body 403, on the outside of the mask. In FIG. 172(A), a cushion is provided on the lower inside portion of the transparent film body 403. Removable or permanent PSA tape is used for adhesion. Then, as shown in FIG. 172(B), the transparent film body 403 is attached to the upper end of the mask 1. FIG. 172(C) shows the state when only the normal mask 1 is worn. If the transparent film body is attached to the mask 1 without a cushion, the surface of the mask 1 is tilted along the nose, so the transparent film body comes into contact with the upper part of the eyes and the forehead. However, as shown in FIG. 172(D), when the transparent film body 403 of the present invention is worn, it has the effect of being comfortable without contacting the forehead, etc. The cushion may be provided across the transparent film 403 in addition to the two locations as in the embodiment. If the cushion is too low, it will come into contact with the forehead, so it is preferable that the cushion has a height of 5 to 30 mm. Approximately 10 mm is preferable. The cushion may be tilted to further prevent it from coming into contact with the forehead. The transparent film 403 is placed in front of the eyes, so both sides are treated with anti-reflection coating to make it easier to see, and furthermore, the inside is treated with anti-fogging coating to prevent moisture and exhaled air from rising to the top through gaps in the mask and humidity from increasing due to body temperature. According to the 136th embodiment, the cushion has the effect of allowing the film transparent plate to be placed away from the eyes.

[0202] The 137th embodiment of the present invention is an invention in which a transparent film body 403 is provided on a transparent plate of the present application (for example, the fifth embodiment, FIG. 10) having a nose cushion, as shown in FIG. 173, where (A) is an expanded front view of the transparent film body 403 provided between the cushion 5 of the transparent plate 4, a side view of the attached transparent film body 403, and a side view of the attached transparent film body 403, and (B) is an expanded front view of the transparent film body 403 having a cushion provided on the outside of the transparent plate 4. When the transparent film body 403 is provided on the inside as in (A), the nose pad cushion 5 is already provided on the transparent plate, so it may be inserted and bonded between the cushion 5 and the transparent plate 4, or may be bonded inside the cushion 5. Also, if the height of the cushion 5 causes the transparent film body 403 to come into contact with the forehead when worn, it may be bonded diagonally inside the cushion as shown in the figure. Also, as in (B), when a transparent film 403 is provided on the outside of the transparent plate 4, the transparent film 403 may be directly adhered, but it is preferable to use a transparent film 403 with a cushion 502 attached. According to the 137th embodiment, there is an effect that an eye protection function can be detachably attached to the transparent plate of the present invention.

[0203] The 138th embodiment of the present invention is an embodiment in which a nonwoven fabric is provided inside the transparent plate or mask of the present invention that corresponds to the position of the mouth and nose when worn, as shown in Fig. 174. Fig. 174(A) is a front view showing that a transparent film body 403 with a cushion 502 adhered to the mask 1 is used to insert a nonwoven fabric 1095 inside the mask 1, and (B) is a side view of the mask when worn. For example, the nonwoven fabric can be an N95 filter 1095, with a width smaller than that of the mask 1 and larger than that of the mouth, and a vertical height sufficient to cover the mouth and nose, and which is adhered to the mask 1 with a removable adhesive or the like so as to be detachable. Figure 174(C) is a front view of the case where nonwoven fabric 1095 is inserted into the product of the present invention, which has a transparent film body 403 attached to a transparent plate 4 with a nose cushion 502 fixed to the head with a rubber band, and (D) is a side view of the product attached. Nonwoven fabric 1095 such as N95 is adhered to the inside of the transparent plate 4 with a removable adhesive. Since the transparent plate 4 becomes slanted when attached to the nose, a slanted cushion 5 or the like is inserted into the transparent film body 403 and adhered to the outside of the transparent plate 4 so that it does not come into contact with the forehead. According to the 138th embodiment, by inserting the nonwoven fabric 1095, the transparent plate 4 and the transparent film 403 do not become cloudy, and droplets from the wearer themselves do not enter the mouth again.

[0204] The 139th embodiment of the present invention is an embodiment in which a bag 1094 into which the nonwoven fabric of the 138th embodiment is inserted is provided, as shown in Figure 175, (A) and (C) are front views of the unfolded mask, and (B) and (D) are side views of the mask when worn. The bag 1094 is adhered to the inside of the mask 1 or the transparent plate 4. The bag 1094 contains a nonwoven fabric 1095, such as N95. Insert from the horizontal direction indicated by the arrow as needed. According to the 139th embodiment, the nonwoven fabric is inserted into the bag, which makes it easy to take the nonwoven fabric in and out, and has the effect of always providing clean nonwoven fabric.

[0205] The 140-1 embodiment of the present invention is a mask 101 for COVID-19, etc., made of plastic, covering the nose and mouth, with a chin pad and ear loops to hold it in place at the chin, as shown in Figure 176(A). The 140-2 embodiment of the present invention is shown in Figure 176(B), P This is a mask 102 for COVID-19, etc., made of rustic plastic that covers the nose and mouth, has no chin rest, and is supported by ear loops 200. The upper sides of the cheeks come into contact with the ear loops 200, but there are gaps between the nose and mouth and the mask. Example 140-3 of the present invention is shown in Figure 176(C), and is provided with a transparent portion 403 at the top of the mask 101. Example 140-4 of the present invention is shown in Figure 176(D), and is provided with a transparent film 403 on the inside of the mask 101 via a cushion 5. Example 140-5 of the present invention is shown in Figure 176(E), and is provided with a cushion 5 on the outside of the mask 101, and a transparent film 403 on the outside of that. Example 140-6 of the present invention is shown in Figure 176(F), and is provided with a cushion 5 on the outside of the mask 102, and a transparent film 403 on the outside of that. This effectively protects the eyes from droplets of viruses and other viruses.

[0206] In the 141st embodiment of the present invention, as shown in Figure 177, the nose cushions 502 are thick enough to allow the mask to be worn without causing any problems when wearing eyeglasses. Figures 177(A) and 177(B) show a view of a naked-eye wearer wearing the mask using, for example, the cushion shown in Figure 170(F), and a top view of the invention of Example 134. In the case of naked-eye wearers, the shape of the upper end of the mask 1 provided with the transparent film 403 does not need to be adjusted to fit the shape of the nose, and the shape of the nose cushions 502 can be changed to fit the nose. However, in the case of a wearer wearing eyeglasses, if the cushioned transparent film is provided on the inside, the nose cushions 502 become quite thick, which can cause the mask 1 covering the mouth and nose to separate from the face, creating gaps. Therefore, as shown in Figure 177(D), a transparent film body 403 with a cushion 502 is provided on the outside of the mask 1, and a nose fitting 1090 such as a wire is used to shape it to fit the shape of the nose when worn. The nose cushion 502 is made thick enough so that the fitting can maintain the shape of the nose, the shape of the lower part of the transparent film body 403 can be deformed according to the shape of the nose, and the adhesion between the mask, cushion, and transparent film body does not come off. Specifically, for example, when using a mask 1 with metal fittings 1090 as shown in Figure 177(D), when worn, the metal fittings 1090, which are shaped to fit the shape of the nose, sink into the nose pad cushion 502 as shown in Figures 177(C) and (E), and the transparent film on the outside of the cushion (transparent film body 403) does not develop large waves or unevenness. The cushion 502 has a thickness of 10 to 30 mm, preferably 20 mm, so that the nose portion can sink in. The transparent film preferably has a thickness of 100 microns or 75 microns. The metal fittings that fit the nose shape can be made of not only wire but also plastic or other materials that maintain their shape. The thickness of the cushion and the metal fittings are selected according to the ease with which the transparent plate can be bent. Figure 177(F) shows another embodiment of the present invention in which cushions 502 are provided on the upper parts of both the front and rear surfaces of the mask 1, and transparent films 403 are adhered to the front of the cushions. That is, cushions 502 are also provided on the inside of the mask of Figure 177(D) above, and cushions 502 are adhered to the upper parts of both the outer and inner surfaces of the mask 1, with the outer cushion 502 being a thick cushion with transparent films 403 adhered to the outside, and the inner cushion 502 being a cushion with a groove that fits the shape of the nose. In Figures 177(D), (C), and (E), metal fittings 1090 are provided on the mask 1, but metal fittings may be provided on the cushion 502 and bonded to the mask 1, or as in Figure 177(F), metal fittings 1090 may be omitted. According to the 141st embodiment, a thick cushion is used, so that even a wearer who wears glasses can use the present invention without contacting the face, and there is an effect that the gap between the face and the product of the present invention can be reduced.

[0207] The 142nd embodiment of the present invention, as shown in Figure 178, is an embodiment in which the transparent plate provided with the head attachment is a film-like transparent body 403, and is worn in a curved state, and when eating, the film-like transparent body 403 can be lifted up (see arrow). Figure 178(A) shows the 9th embodiment (Figure 15(B)) in which the transparent plate is a film-like transparent body 403 of approximately 100 microns. Figure 178(B) shows the 89th embodiment (Figures 108 and 109) in which the transparent plate is a film-like transparent body 403 of approximately 100 microns. When wearing the device, the chin strap can be removed and the film-like transparent body 403 can be lifted to bring food to the mouth. According to the 142nd embodiment, there is an advantage that the transparent film body 403 can be lifted from below to bring food to the mouth while wearing the mask of the present invention.

[0208] The 143rd embodiment of the present invention is, as shown in Figure 179, an embodiment in which, in Example 142 (Figure 178(A)), a plurality of transparent plates 484 or transparent film bodies 403 are used, which are arranged so as to overlap partially, and Figure 179(A) is a front view in which two transparent film bodies 403, for example, of 100 microns, are arranged so as to overlap, and (B) is a front view in which two transparent plates, for example, of 300 microns, are arranged at the left and right ends of the cushion part 5, and transparent film bodies 403, for example, of 100 microns, are arranged in the center so as to overlap each other. The present invention is fixed to the head with a rubber band 6, and the transparent plate and transparent film body are curved and overlapped without any gaps to protect against droplets of viruses such as coronavirus, and when eating, the lower end of the transparent film body 403 is pinched as shown by the arrow, bent and raised upward to bring food to the mouth. The transparent film 403 is not limited to 100 microns, and may be a thin transparent plate of 75 microns or less. According to the 143rd embodiment, (A) has the effect that the transparent film body 403 can be lifted by holding either the side edge or the bottom edge when eating, and can be used for right-handed and left-handed people by changing the overlapping order of the transparent film body 403. In (B), the transparent plates on the sides are about 300 microns thick, and when worn, the two transparent plates 484 and the transparent film body 403 are curved, so there are no gaps even if the respective transparent plates and transparent bodies are not joined, and since the front is the transparent film body 403, it is easier to bring food to the mouth than the center.

[0209] The 144th embodiment of the present invention, as shown in Fig. 180, is an embodiment of the present invention having a transparent film body 403, in which the head contact body is a plate or rod-shaped transparent plate support material 1060 that does not bend, (A) is a front view in which the transparent plate is the transparent film body 403 and the cushion 5 is replaced by a columnar or flat transparent plate support material 1060, and because the transparent plate support material 1060 does not bend, the transparent film body 403 is flat when worn, which has the effect of making it easy to lift the transparent film body and bring food to the mouth. (B) is a front view in which bent transparent plates 484 are provided on the left and right side portions of the transparent film body 403 joined to the transparent plate support material 1060, so that only the center portion can be lifted. The transparent plate support material 1060 is a straight, flat plate 1 to 10 mm thick and 5 to 30 mm wide, or a columnar rod 3 to 10 mm in diameter, and can be made of wood, plastic, metal, hard sponge, resin, etc., as long as it has enough stiffness to prevent bending when attached to the head, and it is preferable that the part that comes into contact with the head is protected with a soft material. According to the 144th embodiment, the transparent film body 403 provided on the transparent plate support material 1060 is in a flat state, and when worn, the transparent film body can be easily lifted, which has the effect of allowing eating.

[0210] 181, the 145th embodiment of the present invention is an embodiment in which the head contact member is composed of a low-curvature transparent plate support material and a cushion portion, (A) is a front view of a transparent film body 403 joined to a low-curvature transparent plate support material 1060, with transparent plates joined to the cushions on the left and right side surfaces, and (B) is a top view. Only the center portion of the transparent plate 484 is made of a transparent film body, for example, 100 microns thick, and is bonded to the transparent plate support material 1060, with a portion overlapping the transparent plates 484 on the left and right sides bonded to the cushions 59. When the present invention is worn, the side transparent plates curve, but the central transparent plate remains flat and uncurved, so that food can be brought to the mouth by lifting the central transparent plate. The width of the central transparent plate and the side transparent plates is optional.

[0211] The 146th embodiment of the present invention, as shown in Figure 182, has an opening with a transparent film 403 at the bottom of the transparent plate, and the head contact body is composed of a low-curvature transparent plate support material and a cushion part with a recess, (A) is a front view and (B) is a top view. A transparent plate 402 with an opening at the bottom is adhered to the center of transparent plate support material 1060, and a cushion portion 514 that is recessed to fit the shape of the forehead is adhered to the back of the transparent plate support material. Transparent plates 486 that are bent into an L shape so as to cover the sides and part of the front of the wearer are adhered to both sides of transparent plate 402 and are provided on transparent plate support material 1060. In addition, a transparent film 403 is attached with PSA adhesive tape or the like to cover the bottom opening of transparent plate 402. When the present invention is worn, the transparent plate 402 and the transparent film body 403 are flat, and the transparent film body 403 is only present in the area that touches the mouth, which has the effect of making it easy to lift and bring food to the mouth. The cushion that conforms to the shape of the forehead also has the effect of making the transparent plate support material 1060 less likely to bend. Furthermore, the transparent plate 486 has an L-shaped side, and rubber bands 6 are attached to the side, which has the effect of reducing the force that pulls the transparent plate support material backward and bends it when worn.

[0212] The 147th embodiment of the present invention is characterized in that the head mounting device is shaped like a glasses frame with temples and supports a transparent plate 486 and a film transparency 403, as shown in Fig. 183, where (A) is a front view of the transparent plate unfolded, (B) is a perspective view of the transparent plate adhered to a glasses frame with temples 1070, and (C) is a top view. By adhering a transparent plate with a double-sided adhesive, which is PSA tape 95, to the top of the glasses frame with temples 1070 as shown in (A), a transparent plate 486 is provided that covers part of the side and front, and a film transparency 403 is provided on top of it, as shown in (B). The corners of the transparent plate 486 are right angles, following the shape of the glasses frame. The product of the present invention is worn by hooking it onto the ears with the temples, and when eating, food or drink can be inserted by lifting the bamboo blind-like transparent film (transparent film 403).

[0213] The 148th embodiment of the present invention, as shown in Fig. 184, is an invention characterized in that in the embodiment 147 (Fig. 183), the eyeglass frame with temples is joined to the transparent plate and transparent film body by hooks 1080, (A) is a perspective view and (B) is a top view. As shown in (A), the temple portion of the eyeglass frame 1070 and the upper part of the hook-shaped hook 1080 on the central eyeglass frame 1070 are turned from the inside to the temple portion and engaged so as not to hurt the face. This allows the transparent plate 486 and the transparent film 403 to be easily attached and detached.

[0214] As shown in Figure 185, the 149th embodiment of the present invention is an embodiment in which the joining method of Example 148 is modified by drilling holes in the top of the transparent plate and passing the temples through them, where (A) is a front view of the transparent plate unfolded, (B) is a perspective view of the transparent plate fixed to an eyeglass frame with temples 1070, and (C) is a top view. The two holes 4861 on one side are sized to allow the temples of the eyeglass frame to pass through, and since the transparent plate 486 is about 300 microns apart, it is best to leave the two holes about 20 mm apart. Furthermore, the transparent plate 486 and the transparent film 403 are joined at the overlapping upper part with transparent plate connecting tape 49, so the transparent film 403 will not fall off. This allows the transparent plate or film to be easily attached to the frame of the eyeglasses without damaging the frame itself.

[0215] The 150th embodiment of the present invention, as shown in FIG. 186, is characterized by the provision of slit-shaped holes 4061 in a transparent plate 406 having an opening at the bottom for attaching a mask, through which a mask is inserted and integrated with the transparent plate. (A) is a front view of the product of the present invention unfolded. A mask (e.g., a known nonwoven mask with ear straps) is inserted into opening 4023 in transparent plate 406, which has an opening for attaching a mask and a through-hole, and the mask's ear straps are passed through slits 4061, integrating the mask and transparent plate 406 to wear the product of the present invention. Because the mask's ear straps pass through slits 4061 in transparent plate 406, they do not fall off and are in close contact with the mask. The mask protects against droplet infection from the mouth and nose, and transparent plate 406 protects the eyes. The thickness of the transparent plate 406 may be about 300 microns so that it can be curved, or about 100 microns so that it can be bent. The width of the transparent plate should be about the same as the width of the face so that it does not interfere with putting the ear loops of the mask over the ears. The size and position of the opening 4023 in the transparent plate is determined so that the width is narrower than the width of the mask so that the transparent plate and the mask overlap, and the upper edge of the opening also overlaps with the upper part of the mask. This overlap is about 5 to 10 mm. The slits 4061 need only be wide enough to allow the ear straps of the mask to pass through, and are provided so that the mask fits into the opening of the transparent plate. The method of integration is to align the mask from the inside of the transparent plate 406, insert the left and right ear strings of the mask into the left and right slits from the inside of the transparent plate, align the position of the mask with the position of the opening of the transparent plate, and attach the ear strings on the outside of the transparent plate to the ears to use. This allows the mask to be integrated with a known mask without using adhesives or extra tools, making it low-cost, convenient to carry, and disposable.

[0216] The 151st embodiment of the present invention, as shown in Figure 187, uses a head mount in the shape of a temple-shaped eyeglass frame. It includes a curved, approximately 300-micron-thick transparent plate 4 with an opening in the center of the bottom, and a transparent film body 403. (A) and (B) are perspective views, and (C) is a top view. The transparent plate 4, which has the transparent film body 403 in its center, is fixed to the temples of the eyeglass frame 1070, resulting in a curved overall shape. (A) shows the transparent film body 403 attached to the top of the transparent plate with transparent adhesive tape 49, while (B) shows the transparent film body 403 attached approximately halfway down from the bottom of the transparent plate. The transparent film body 403 is 50 to 100 microns thick. For example, if the transparent film body 403 is approximately 75 microns thick, lifting the transparent film body 403 as shown by the arrow will either lift it partway and return to its original position, or the film will bend and stick to the upper transparent plate, preventing it from returning to its original position. This can be adjusted by the lifting method. The transparent film 403 and the transparent plate 4 overlap with the transparent film 403 on the outside, with the overlap amount being 5 to 20 mm, with 10 mm being preferable. The width of the transparent adhesive tape 49 is 15 to 20 mm. The overlap amount should be as small as possible because double overlapping reduces visibility, but if the overlap amount is too small, gaps will form between the transparent film 403 and the transparent plate 4, making it impossible to prevent splashes. The present invention has the effect of making it easier to bring food to the mouth during meals. In (D), the head attachment is a single rubber band, and a transparent film body 403 is attached to a transparent plate 4 of about 300 microns in thickness with a cushion 5 having an opening, and is connected with a connector 4024 such as transparent PSA tape, and is used by bending it when worn. When the transparent film body 403 is lifted during a meal, the bending makes the transparent film body 403 one with the upper part of the transparent plate 4, creating an opening without the need to support it with one's hand.

[0217] The 152nd embodiment of the present invention, as shown in Figure 188, is characterized in that it can be rolled up into a scroll and carried around. (A) shows a transparent film 403 about 100 microns thick, with a cushion 5 and rubber band 6 at the top, which serve as the head contact portion, and as shown by the arrow, it is rolled up like a scroll around the cushion 5 as the axis. The transparent film 403 has a thickness of 50 to 100 microns, which is a thickness that can be rolled up. (B) shows a cross section seen from the side when rolled up, and by inserting it directly into a cylindrical case 264 as shown by the arrow, it has the unique effect of being convenient to carry around. To make it ultra-lightweight and rollable, the size of the transparent film 403 is B5 landscape or A4 landscape, the cushion 5 is small, for example, about 10 mm thick and 15 mm wide, and the rubber band 6 is also preferably 10 mm wide and 0.5 to 1 mm thick. The product of the present invention weighs 8.9 grams, making it the lightest in the world, and has the added advantage of being extremely light and easy to carry. The sizes of the transparent film 403, the cushion 5, and the rubber band 6 are not limited to those mentioned above, and any form in which they can be rolled up around the cushion as an axis is included in the present invention. Figure 1C) shows the product of the present invention (A) with the male and female hook-and-loop fasteners 8 attached to the lower side of the transparent film body 403, spaced apart by a distance equivalent to one circumference of the film when rolled up. Figure 1D shows a cross-sectional view of the product of the present invention (C) rolled up and fastened with hook-and-loop fasteners 8. Because the hook-and-loop fasteners 8 secure the product, it does not come apart and is portable without the need for a case. Figure 1E shows the present invention rolled up and fastened with a removable PSA tape 96 made of tetrafluoroethylene resin. When rolled up, this can be used as a fastener as shown in Figure 1F. Alternatively, this tape can be separated and, as shown in Figure 1G, removable PSA tape 96 made of tetrafluoroethylene resin can be applied to the fingertip from the nail to the pad. For example, by pressing a telephone button with the part with the tetrafluoroethylene resin tape 96 applied, viruses such as the novel coronavirus do not adhere to the fingertips, and the mask and tape effectively protect against both airborne and contact infection. The PSA tape may be a sheet containing copper in add...
