Abstract

An instrument and Method for wearing maf''l that made of a sheet of foamed plastic material that is spongy, flexible, and soft. And straps that laced in holes that in it, it is a rectangle that have a bulge in it's upper side, in the shape of a trapeze The size of the rectangle the number of the straps and holes is variable as is needed. The wearing of the maf''l will be done in this way, we adhere to the upper lip above the mouth, the upper side of the rectangle, so the middle part of the upper strap, that is in the front of the sheet, is parallel to the lip. We pass the edges over the ears and tying them in the back of the head, so the maf''l is fixed because this 4 point, especially under the nose. When we tightening the strap, the front part of that is the middle part of the strap, is pressing of the upper side of the rectangle to the lip. So the bulge is adhered to the nostrils in the nose, this causes that there is a good sealing in the nostrils and all the air that is breathing through the nose, is passes just through the sheet of the material of the bulge. In order to improve the efficiency of the maf''l, we are wetting the sheet of the material with disinfection fluid in the area of the nose and the mouth. So this makes the maf''l more effective mean for trapping the tiny drops of saliva and catarrh in the air, when the human that wear the maf''l: inhaling, puffing, sneezing, coughing and talking. When a human that is in front of the human that wear the maf''l: inhaling, puffing, sneezing, coughing and talking, and when the human that wear the maf''l, is in a place that a human left in the air tiny drops of saliva and catarrh. The disinfection fluid destroy the viruses and microbes that trapped. The wetting can be done in few ways, one of them is that the bulge part of the maf''l is bended down for the user can drop in the inside of the bulge part disinfection fluid, at the end the bulge get back and protect the nose. Because the characters of dispersion, draining and evaporation, of the fluids that were accumulated, in the sheet of the plastic material, this enable to add new disinfection fluid to the place that became empty, during the wearing of the maf''l for a long time without the need to take them down. We can wear the maf''l kind nose under surgical mask to improve the protection to usual people and people with beards and separating between the nose and the mouth.

Description

A Mask and A method for filtering and purifying air that comes in contact with human being through: respiration, face and eves.

The field of invention:

God created the human being so that all the time he would be depended on three things to continue living: food, drink, and air, so that the human being would continue be connected to God all the time, But they depend on three types of toil to obtain them:

A. The food - Especially the bread, which the person needs with a low level of urgency, it can reaches to him just after he has toiled on it a lot.

B. Drinking - Mainly the water, which the person needs with a higher level of urgency relative to food, it can reaches him only after he has toiled on them but to a lesser extent.

C. The air for breathing - That the human being needs at any moment so that he can continue to living, it reaches him free at any moment without any toil at all.

The air pollution that human created, the diseases that are transmitted through the air, the living in a crowded urban society and the use of crowded means of transportation, caused the air to become dangerous to the human even though it is given for free.

Because of its necessity, the human has no choice and must continue to breathe the air, this situation has caused human obliging task that he must toil to purify the air so that his respiratory system will be protect.

This task cannot be ignored at all, the pollution severely harms human health, the diseases transmitted in the air cause enormous damage to human health, this also paralysis social life, until we got in to the unusual situation of quarantine all over the world.

Background on the invention:

Some of the background was took from a report published on March 28, 2020 on the

Ca lea list newspaper's website: https:/www.calcalist.co.il/internet/articles/0,7340,L- 3803792,00.htm

For many years, face masks have been developed to be used personally for each person to reduce the harm from air pollution, and to prevent infection of airborne diseases by humans. In the ancient times, they used a simple and quick solution of covering the nose with a scarf to prevent damage from substances that smelled bad.

In the Middle Ages, they used to make and wear a face mask with a long beak that resembled a bird, the long beak of the mask had two holes through it, which incense was introduces into them to overcome the bad smell, they thought that the bad smell is bringing the diseases. (Perhaps, It was the inspiration for the "Passover Haggada", called the "The Birds Heads Haggada", in this Haggada the heads of the men were painted as bird heads.).

About 150 years ago, in the Jewish law literature, was a description of the use of a face mask during an epidemic, which was then like a bandage or a scarf, Rabbi Israel Meir HaCohen of Raddin in Russia, that is famous after his book "Hafetz Chaim", wrote in his book "Mishna Berura" : " ... And forcing him, when he outgoing, to wear around his nose and mouth a piece of camper...." [Camper = compress].

About 110 years ago, in China was developed against airborne diseases, the face mask that is the basis of today's face masks, it contained several protective layers.

About 100 years ago in The World War I, was developed the face mask with the anti-gas filter, which is until today useful for military and civilian defense purposes. These masks were large and cumbersome, it was difficult to breathe through them, and they greatly warm the faces of those who wore them, (today they have the same problems).

About 50 years ago, it was the beginning of the development of the "disposable face masks."

Review of things that are existing in the market and that are related to the

Patent:

1) A CPAP device for treating respiratory disorders during sleep that is pumping air to the patient, model Prisma-Smart manufacturer Levinstein. It has an air filter made of foamed plastic material that is spongy and flexible. Its size is 6x37x63 millimeters for use with a 32x52 millimeter air entry hole. The air pressure is in the range of 4-20 cm water, which is the range of pressures during breathing. The device is depicts on the company's website http://www.icpap.co.il/.

2) An air tube that comes out of the CPAP device and attaches the face mask that the patient wears during sleeping. There are three types of masks that made of silicone: One - which covers the nose and mouth, the second - that covers only the area of the nose and the third - that covers only the nostrils of the nose. The good sealing is be formed by the pressure generated on the nose when tying the mask to the head, and because the soft mask material in the nostril area of the nose, and in the edges. This mask is depicts in the address: https://www.youtube.com/watch?v=fvpIBCVmjDw.

3) In a device that measures carbon dioxide, a water trap is attaches for trapping the moisture and tiny drops of water, from the air that coming out of a ventilated person. In their presence the detector of the device does not work, so this air is inserted into an array of tubes and narrow passages, in the water trap that traps them, this is depicts in the website of Drager company : . https ://www.draeger.com/en.uk/Products/waterlock-2.

4) Solutions of salt that sold in all pharmacies, for hilling and purifying breathing system by: inhalation, rinse and dropping, against viruses and microbes. Are advisable by medical agents for example the Wolfson hospital, this is depicts in the website:

5) Copper fibers are combined in a face mask by MedCu company to destroy viruses in the air that passing through it, this is depicts in the report: https://tech.waIla.co.il/item/3350134.

6) Face masks that are not soft and flexible caused with safety glasses, after few hours of wearing, signs of pressure wounds, this is depicts in the report: https://www.Inn.co.il/News/News.aspx/434242.

7) For many people it is not comfortable to wear a face mask, therefor they wear it partially or remove it at all sometimes, especially when they talk in the phone, it is very dangerous, this is depicts in the report: https://www.ynet.co.il/health/article/r1VVS3Bu8. 8) In a military face mask for ABC, it was designed for use in a long term of time, therefor there is a pipe to drink water and separations between the: eyes, nose and mouth, this is depicts in the page of the company Shalon that manufacture it: http://www.shalon.co.il/WEB/8888/NSF/Web/1114/shalon%20prospect%20milresp-

9) For men that have a beard even military face mask for Abe are not sealing, therefor there is a blower that always supplies through a pipe , purified air to the military face mask. In simple face mask just 60% of the air is being purified, this is depicts in the report from April 20: Https://www..rrjsn.com/he-y/health/rngd

10) In a research that was done in Japan in March 2021, was founded that a surgical mask made of non-woven material were blocking viral spread in different percentages: 69% - when was wearing loose-fit, 81% - when was wearing fitted and 89% - when was wearing fitted and a polyurethane mask above it, this is depicts in the report: https://www.reuters.com/article/us-health-coronavirus-japan-supercompute- idUSKBN2AX0BA.

11) A wide research was done in 2020 year by the Ada- American Dental Association - https ://www.ada,org/en , 73 % of the dentists used mostly face mask and other means and most of them take care that the patients will be protected in the waiting, an abstract of this research is depicts in the report: https://pubmed.ncbi.nlm.nih.gov/33071007/.

The definition of the invention:

Introduction and a short description:

Our mask is a face mask that combining a method for purifying and filtering air that a human being is breathing. The exclusive and the innovative of the invention are depict in relation to patents and of things that are existing in the market that where detailed in the previous article of the background on the invention, here we relate to a part of them when the main is the definition of the invention:

1) The sheet of the material is made from one layer of a foamed plastic that is: spongy, flexible, soft and light weight - in the other face masks the body of the masks are made from multilayer.

2) The upper strap that is used to tie the mask to the head is also used as a separator between the nose and the mouth, together with a part of the one layer of the foamed plastic. - In other face masks the straps are used just to tie the mask to the head and they are not separating between the nose and the mouth. So, when puffing from the nose warm air is getting to the mouth zone and accumulates under the mask, When inhaling back, comes to the nose warm air that was warmed near the mouth.

3) The upper strap that is used to tie the mask to the head, is also used as a mean to create good seal near the nostrils of the nose, by tightening a part, of the one layer of the foamed plastic, to the nostrils. So there no air that is getting in and getting out the nose, that passing not through the one layer of the foamed plastic - In other face mask the straps are used just to tie the mask to the head, therefor there is no sealing between the mask and the skin of the face. So when inhaling from the nose there is air that penetrate, between the edges of the face mask and the skin of the face too, and not just through the layers of the mask, therefor there is no full filtering. There are masks that in the edges is a gel like material but still it is not full sealing. In CPAP and military masks there is a good sealing. But in disposable masks in the medical and civilian markets it is not existing. 4) The separation between the nose and the mouth, and the sealing of the nose, reduces the passage of the air to the glasses that wear the mask user, therefor it prevents mostly, fog forming on the glasses with breathing. - In the common face masks, that there is not separation between the nose and the mouth, and there is not sealing of the nose, there is many fog forming on the glasses with breathing. There are face masks that have a metal wire on the nose place in the mask to reduce the fog forming, but it dose not solves the problem. 5) The upper strap that is used to tie the mask to the head. Is also used as a mean to fix the mask on it's place, because it passes on 4 places that create together stability: Under the nose with the part of the one layer of the foamed plastic, Above the two ears and In the back of the head. - In the other face masks, the straps are tying to the head. In the back of the head or in the back of the ears, so they are not stable and shift from there place. Or upper and then the mouth is be exposed or down and then the nose is be exposed. 6) The softness of the material that the sheet of the mask is made, gives a comfortable touch to the skin of the face of the user and an excellent sealing. - In other face masks that are not flexible, the strong tying causes to an uncomfortable pressure of the skin of the user, nevertheless the sealing is partial and not good. 7) The tiny air cells in the sheet of the plastic material, they are of the kind of open cells that are dispersed randomly .Thus the passage of the air through the sheet of the material is dispersed and not in a straight line, so this is increasing the filtering of the air that breathed through it. Because the thickness of the material that works as a filter is greater than the actually thickness of the material- In other face masks, just the actually thickness of the sheet is working as a filter, and it is very thin. 8) The tiny air cells in the sheet of the plastic material in the kind of open cells, are using as water trap because there are many narrow passages through them, as in a water trap in a device that measures carbon dioxide from the air that coming out of a ventilated person. - In other face masks there is not this action because they are very thin, there are few masks that do trap the water but after a short time they become blocked and not effective. 9) The tiny air cells, in the sheet of the plastic material, are used as a reservoir for the disinfection fluid. That we wetting the sheet of the plastic material ahead, or dropping drops in to the sheet, during the wearing it, with a new disinfection fluid. Thus the efficiency of the mask is being kept all the period of time of the usage - In other face masks there is not a place to store fluid, but there are masks with a solid layer that can disinfection, but after a short time the efficiency vanishes. 10) The tiny air cells, in the sheet of the plastic material, that contain disinfection fluid improves the efficiency of the mask to filter, and adsorbs tiny particles. Therefor, clean air is getting to the nose all of the period of time of the usage - In other face masks there is not a place to store fluid in them, There is a disposable mask that accumulate fluid from the air but after a short time the efficiency vanishes.

11) The tiny air cells in the sheet of the plastic material in the kind of open cells, are creating the characters of: dispersion, draining and evaporation, of the fluids that were accumulated in the sheet of the plastic material. So, fluids that were accumulated in specific region in the sheet of the plastic material, are dispersing to all area, then a part of them is draining and sinking, and a part of them is evaporating out to the air. Thus the mask is not getting block. - In other face masks, because they are thin they are getting block after a short time and there efficiency vanishes. In one patent there is a description of a mask with layers for draining but it is complicated and expensive.

12) The natural humidity in the air, the tiny drops of saliva and catarrh, that were trapped and accumulated in the tiny air cells, in the sheet of the plastic material in the kind of open cells, and the air that is passing through it. Are getting in touch with the disinfection fluid that before was dropped in the sheet of the plastic material, so the viruses and microbes are destructed. Later, those fluids are dispersing, draining and it's water part evaporating, thus evacuated place for a new disinfection fluid and the efficiency of the sheet of the plastic material is being kept all over the time of usage. - In other face masks with a solid layer that can disinfection, after a short time the efficiency vanishes.

13) The tiny air cells in the sheet of the plastic material in the kind of open cells and the characters of the plastic material, gives the possibility to immerse and wash the plastic material each end of day after the usage. Thus it is ready to another usage like a new one, actually it is a long use not disposable mask. - Other face masks are disposable, after a short time the efficiency vanishes and they have to be throwaway.

Our mask is protecting, mainly of the breathing from the nose, by trapping the tiny drops of the saliva and the catarrh in the air, but because there are some kinds of masks that are protecting more parts of the face too. Therefor we will call our mask in very briefly: MAF"L, in Hebrew it is acronym of: mask, nose, face and trap.

They will be manufacture in some kinds according the constraints of the user and the environment, and in few sizes according the age of the user.

Summery:

The maf"l gives an innovative and an excellent solution, to filter and to purify better the air that breathing who wear it, instead the usual face mask that was invented 100 year ago, and instead the surgical face mask that is for use in surgery room that the air there is clean and filtered.

The innovation is resulting of that, that the maf"l is made of unique material with special characters and special shape that other face mask in the market do not have. With a special method to wear the maf"l that causes the separation between the nose and mouth, and causes an excellent sealing to the nostrils in the nose.

With a special method to add disinfection fluid to the maf"l when the user wear it.

All of this cause to a breakthrough, that gives a new direction that gives the possibility to the wearer to protected himself excellently against infection and not infect other people.

The definition of the invention detailed:

In a superficially view it is a simple mask, but after we will see the four great advantages of the invention we will understand that the maf"l is a breakthrough:

A. 1) The characters of the sheet of the material that the maf"l is made from, that are: Foamed, spongy, flexible, soft and light weight, together with the shape of a rectangle that have a bulge in it's upper side, in the shape of a trapeze, create those characters:

1) The high flexibility and softness of the sheet causes an excellent sealing to the nostrils in the nose, so there is excellent protection when breathing through the nose in: inhaling, puffing and sneezing.

2) The shape and the flexibility of the sheet causes good isolation around the mouth, so there is a protection when breathing through the mouth in: inhaling, puffing, sneezing and coughing.

3) The basic flat structure of the sheet together with the flexibility and the springy characters cause to a stability of the structure of the maf"l when is tying to the head.

4) The sheet of the material manufactured in some densities, 18-60 kg for cubic meter, as it needed, so it flexible, soft, light weight and comfortable for use.

5) The flexibility and softness of the sheet causes a good fitness between the maf"l and the face when it's tied to the head of the user.

6) The flexibility and softness of the sheet causes that there will not be any pressure on the face when the maf"l is tied to the head of the user, this gives a good feeling.

7) The flexibility and porous of the sheet causes that will be comfortable to talk through it and to another human to hear through it.

8) The flexibility and simplicity of the sheet causes that it is easy to wear the maf"l.

9) The flexibility of the maf"l gives the ability to cover easily and comfortably some important areas on the face as is need to protect.

10) In all the sheet of the material of the maf"l there are tiny air cells in kind of open cells that are dispersed randomly, that makes the maf"l an effective filter with a large filtering area and thickness that is more thick then the thickness of the sheet. 11) In all the sheet of the material of the maf"l there are tiny air cells in kind of open cells that are dispersed randomly, that makes the maf"l an effective mean to filter poisons and pollutes in the air when inhaling.

12) In all the sheet of the material of the maf"l there are tiny air cells in kind of open cells that are dispersed randomly, that makes the maf"l an effective mean that is trapping the tiny drops of saliva and catarrh in the air, when the human that wear the maf"l: inhaling, puffing, sneezing, coughing and talking. When a human that is in front of the human that wear the maf"l: inhaling, puffing, sneezing, coughing and talking, and when a the human that wear the maf"l, is in a place that a human left in the air tiny drops of saliva and catarrh.

13) In all the sheet of the material of the maf"l there are tiny air cells in kind of open cells that are dispersed randomly, this character makes the maf"l an effective mean that is dispersing the air to all of the front space, that the maf"l wearer puffing through the sheet. When the maf"l wearer inhaling through the sheet, the air comes from all of the front space. The air passes the sheet of the maf"l not in a straight line.

14) In all the sheet of the material of the maf"l there are tiny air cells in kind of open cells that are dispersed randomly, this character makes the maf"l as a reservoir for the fluids that were accumulated from the tiny drops that were trapped.

15) The material and the structure of the maf"l with the simplicity, make it as a cheap cost to manufacture and a cheap cost of material.

16) The kinds of the foam plastic to manufacture the maf"l is: or polyurethane, or silicon, or any plastic material that has the characters that needed. It is forbidden to use flame retarder additives because they emission poisonous gases.

17) There is a priority to use polyurethane because it resistant to mold and odorless. When manufacturing polyurethane it's color is white, later when it exposes to sun light the color became yellow but it's characters are not changed.

B. The exclusively of tying the upper strap that passes under the nose creates the following characters:

1) When tying the upper strap, we put the upper side of the rectangle on the upper lip above the mouth, and the bulge that in the shape of a trapeze, near the nostrils in the nose. When we tightening the strap, the front part of it is the middle part of the strap, is pressing of the upper side of the rectangle to the lip, so the bulge that in the shape of a trapeze, is adhere to the nostrils in the nose. This causes that there is a good sealing in the nostrils and all the air that is breathing through the nose, is passes through the sheet of the material of the bulge that in the shape of a trapeze.

2) This tightening of the strap causes to a separation between the nose and the mouth, so air that coming out from the nose do not reach to the mouth, and the area of the mouth is not getting warm because the air that coming out nose us warm and wet. This gives a good feeling comparatively to a human that wear usual face mask that there is no separation, so air that coming out from the nose reaches to the mouth, and the area of the mouth is getting warm and this is not comfortable. 3) When talking, air that coming out from the mouth do not reach the nose because of the separation this gives a good feeling, Comparatively to a human that wear usual face mask that there is no separation, air that coming out from the mouth reaches the nose, causes warming that is not comfortable for the breathing. 4) The separation between the nose and the mouth, and the sealing of the nose, reduces the passage of the air to the glasses that wear the maf"l user, therefor it prevents mostly, fog forming on the glasses with breathing. Comparatively to a human that wear glasses with usual face mask. 5) The upper strap that used to tie the mask to the head. Is also used as a mean to fix the mask on it's place, because when we tightening the strap, the front part that is the middle part of the strap, is pressing of the upper side of the rectangle to the lip under the nose. 6) The upper strap that used to tie the mask to the head. Is also used as a mean to fix the mask on it's place, because it passes on 4 places that create together stability: Under the nose with the part of the one layer of the foamed plastic, Above the two ears and In the back of the head. 7) In all kinds of maf"l the strap can be tied in the back of head that is easily can be untie or using buckle. When a stretch strap is in used, first, we fix the length and then we put a buckle. If we connect the strap without buckle the starching character can be used as holder. We must pay attention that the connection of the strap will not disturb the breathing. 8) The softness of the material in the maf"l, gives a comfortable touch to the skin of the face of the user and an excellent sealing, so even when we tie the strap, signs of pressure wounds are not created, in other masks it happens. 9) For people that has limitation about the ability to cover all there face, because medical reasons or other, the maf"l will be manufacture in some kinds according the constraints of the user and the environment. Even so there will be differences in all the kinds of the maf'ls, the protection of the breathing through the nose will remain excellent:

I. Nose and mouth and cheeks and forehead, with two straps, upper and lower, when the lower strap improve the isolation around the mouth, there are little holes for the eyes, so the eyes and the forehead are excellent protected.

II. Nose and mouth and cheeks and forehead, with one strap the upper, there are more bigger holes for the eyes, so the eyes and the forehead are good protected.

III. Nose and mouth and cheeks, with two straps, upper and lower, w hen the lower strap improve the isolation around the mouth, and the cheeks are good protected. IV. Nose and mouth and cheeks, with one strap the upper, it is possible to clean and drink with mouth, the cheeks are good protected.

V. Nose and mouth enlarged, with one strap the upper, that connected to the sheet of the material with 4 holes that gives quit good protection around the mouth.

VI. Nose and mouth, with one strap the upper, that connected to the sheet of the material with 2 holes that gives partial protection around the mouth.

VII. Nose with one strap, that connected to the sheet of the material with 2 holes, that cover just the nose but the protection of the breathing through the nose will remain excellent.

VIII. Nose with one strap, that connected to the sheet of the material with 2 holes, but is wearing under usual mask: surgical, cloth etc.

C. The disinfection fluid that we add to the sheet of the plastic material neat the nose and the mouth creates those characters:

1) I order to improve the efficiency of the maf"l, we are wetting the sheet of the material with disinfection fluid in the area of the nose and the mouth. So this makes the maf"l more effective mean for trapping the tiny drops of saliva and catarrh in the air, when the human that wear the maf"l: inhaling, puffing, sneezing, coughing and talking. When a human that is in front of the human that wear the maf"l: inhaling, puffing, sneezing, coughing and talking, and when the human that wear the maf"l, is in a place that a human left in the air tiny drops of saliva and catarrh. The disinfection fluid destroy the viruses and microbes that trapped.

2) I order to improve the efficiency of the maf"l during the day, we add drops of disinfection fluid to the bulge that in the shape of a trapeze, we do it by bending the bulge with a finger.

3) We can use a little bottle with a little pump.

4) It forbidden to use a sprayer because it is dangerous for the eyes.

5) We can wet the maf"l near the mouth with an open bottle from outside.

6) The tiny air cells, that contain disinfection fluid improves the efficiency of the maf"l to filter, and adsorbs tiny particles. Therefore, clean air is getting to the nose all of the time of the usage.

7) The disinfection fluid destroy the viruses and microbes that was trapped in the maf"l and in the air that passing through.

8) The disinfection fluid that is recommend for use is what got approval from the medical authorities and will not damage the material of the maf"l.

9) Sensitive people will ask his doctor.

10) An inexpensive disinfection fluid a solution I teaspoon of salt in 1 coup of water.

11) Such solution of concentration of 3% is selling in pharmacies for many years and for many uses in the breathing system of the human.

12) If there is not disinfection fluid, it can be wet with water.

13) Wetting the maf"l causes cooling when is needed. 14) In a cold weather, the salt decrease the freezing point.

15) In a very cold weather, it can be added alcohol to the solution to decrease more the freezing point.

16) The maf"l can be used as an inhalator with medical approval.

17) The wetting of the maf"l can put it in a standard for mask against fire if is need.

D. The good resistance of the material that the maf"l is made, together with the ability to drain and evaporate, gives the maf"l the character of long use not disposable mask and the character to operate effectively for a long time:

1) The sheet of the foamed plastic material is in use for long years and can withstand for long years, after immersing and washing, it can be used as a new.

2) The tiny air cells in the sheet of the plastic material, in the kind of open cells, are creating the characters of: dispersion, draining and evaporation, of the fluids that were accumulated in the sheet of the plastic material. So, fluids that were accumulated in specific region in the sheet of the plastic material, are dispersing to all area, then a part of them is draining and sinking, and a part of them is evaporating out to the air, thus it not get block .

3) Those characters enable to add new disinfection fluid to the place that became empty, during the wearing of the maf"l for a long time without the need to take them down.

4) In other face masks, because they are thin they are getting block after a short time and there efficiency vanishes.

5) At the end of the day we immerse and wash the maf"l and it can be used as a new, so the maf"l is a long use not disposable mask.

Description of the numbered parts in the drawings:

[The number in the square brackets marks the drawings that there is the part] [1-2, 4-5] The maf"l for nose and mouth and cheeks, made from sheet of plastic material that foamed, spongy, and flexible, that contain tiny air cells in kind of open cells, that protects the nose and mouth and cheeks, the size of the rectangle: Length 23-27 c"m, height 11-12 c"m, thickness 1-1.5 c"m. [1-21]The bulge that in the shape of a trapeze, that is in the middle of the upper side of the rectangle in all the kinds of the maf"l: Nose, nose and mouth, nose and mouth enlarged, nose and mouth and cheeks. In the maf"l kind of nose and mouth and cheeks and forehead, the bulge is between the 2 rectangle holes for the eyes. The bulge designed to seal the nostrils, and all the air that is breathing through the nose, is passes through the sheet of the material of the bulge and will be filtered and purified. The size of the bulge that in the shape of a trapeze: upper base length 3-4.5 c"m , lower base length 5-7.5 c"m , height 1.5-2 c"m. The bulge is cut off for not disturb the looking. Everybody can cut it as he need but must pay attention not hurt the sealing. [1-21]The upper strap to tie the maf"l to the head, is laced in the sheet of the material in 2 or 4 upper holes. They are 1.5-3 c"m in distance from the upper side of the rectangle. In a maf"l that protects the forehead too, the distance is measured from the lower side of the 2 rectangle holes for the eyes. The two middle holes are beneath of the low edges of the trapeze (2). The two outer holes are in distance of 3-5 c"m from the edges of the maf"l. The thickness of the upper strap must to be 0.8-1.2 c"m to get a good sealing in the nose by the bulge. The section of the strap can be round or rectangle, but if it is a rectangle we must to take care that the wide thickness of 0.8-1.2 c"m will be attached to the sheet of the maf"l, the narrow thickness can be at least of 0.3 c"m. [1-2,4-5,20-21] The lower strap to tie the maf"l to the head, is laced in the sheet of the material in 4 lower holes. They are 1.5-3 c"m in distance from the lower side of the rectangle. The two middle lower holes are beneath the two middle upper holes. The same is for the 2 outer lower holes. The thickness of the lower strap can be 0.3- 0.5 c"m. [1-21] [In 10,15,16 it not seen but exists] The front part that is the middle part of the upper strap works in this way. When tying the upper strap, we put the upper side of the rectangle on the upper lip above the mouth, and the bulge that in the shape of a trapeze, near the nostrils in the nose. When we tightening the strap, the front part of that is the middle part of the strap, is pressing of the upper side of the rectangle to the lip, so the bulge that in the shape of a trapeze, is adhere to the nostrils in the nose. This causes that there is a good sealing in the nostrils and all the air that is breathing through the nose, is passes through the sheet of the material of the bulge that in the shape of a trapeze. It also causes to separation between the nose and mouth. [1-2,4-5,20-21] The front part that is the middle part of the lower strap, that is in the lower side of the rectangle, is designed to tightening the lower part of the maf"l under the mouth and chin to get more sealing.

Detailed description of the invention:

For maf"l kind nose and mouth and cheeks, with two straps, as described in fig. 1, 2,4,5 and with one straps without fig.: We take maf"l (1) made from sheet of plastic material that foamed, spongy, and flexible, so that the bulge that in the shape of a trapeze (2) is up. If the maf"l (1) comes without straps (3) and (4) laced in it, we lace them in the way of stitching. The upper strap (3) we lace in to 4 upper holes (40), The lower strap (4) we lace in to 4 upper holes (41). We aimed that the front parts of the straps (5) and (6) will be in the front side of maf"l (1), while the back side of maf"l (1) will be attached to the face of the user (10) or (14) or (15) in the maf"l (1). When we make the straps (3) and (4) from un stretchy material, we pick up the two edges of the upper strap (3) and put them after the back of head of the user (10) while the fourth of the strap (9) will be above the ears. We adhere to the upper lip above the mouth the upper side of the rectangle. So the middle part (5) of the upper strap (3), that is in the front of the sheet, is parallel to the lip above the mouth and under the nose. So the bulge is adhered to the nostrils in the nose and bending to the front as we see clearly in fig. 6. We are tying the upper strap (3) in the back of the head in a tie (7), strong but comfortable that can be easily untied. We find out that there is a good sealing in the nostrils of the nose, by that the bulge (2) is adhered to the nostrils and bended to the front so it is parallel to the nostrils. This causes that there is a good sealing in the nostrils and all the air that is breathing through the nose, is passes just through the sheet of the material of the bulge. We must pay attention that the tie including 4 things: strength, comfortable, sealing and good breathing. If we use an upper strap (3) with a rectangle cross section, we must to take care that the wide thickness of 0.8-1.2 c"m will be attached in parallel to the sheet of the maf"l. If we use an upper strap (3) with a round cross section, we must to take care that the thickness of the strap is important to create a good sealing in the nostrils of the nose by the bulge (2). We are tying the lower strap (4) in the back of the head in a tie (8) that can be easily untied and that do not have to be strong, while the fourth of the strap will be under the ears so there will a partial sealing in the nose and chin. The thickness of this strap can be 0.3-0.5 c"m. When un stretchy straps are in used, we can use 2 buckles (12) and (13), instead of ties (7) and (8). Then first we fix the length and then we put a buckle. We get that maf"l (1) protects the face (except the eyes and the forehead) against infected fluids. We get an excellent sealing in the nostrils so all the air that is breathing through the nose, is passes through the sheet of the material of the bulge that in the shape of a trapeze (20). We get that maf"l (1) protects the mouth by partially sealing, and when talking. We get that maf"l (1) causes to separation between the nose and mouth. We get that maf"l (1) causes that the tiny air cells in the sheet of the plastic material, they are of the kind of open cells that are dispersed randomly .Thus the passage of the air through the sheet of the material is dispersed and not in a straight line, so this is increasing the filtering of the air that breathed through it. Because the thickness of the material that works as a filter is greater than the actually thickness of the material. We get that maf"l (1) causes the tiny air cells in the sheet of the plastic material, they are of the kind of open cells that are dispersed randomly, are using as water trap because there are many narrow passages through them. So there is excellent protection when breathing through the nose in: inhaling, puffing and sneezing and so there is a good protection when breathing through the mouth in: inhaling, puffing, sneezing and coughing. By wetting maf"l (1) disinfection fluid in the area of the nose (2) and the mouth before and during the wearing. In fig. 4 and 16 by dropping (17) and in fig. 5 by bottle (19) , makes the maf"l (1) more effective mean for trapping the tiny drops of saliva and catarrh in the air, when the human that wear the maf"l: inhaling, puffing, sneezing, coughing and talking. When a human that is in front of the human that wear the maf"l: inhaling, puffing, sneezing, coughing and talking, and when the human that wear the maf"l, is in a place that a human left in the air tiny drops of saliva and catarrh. We can use a little bottle with a little pump in it's head. It forbidden to use a sprayer because it is dangerous for the eyes. By wetting maf"l (1) disinfection fluid the tiny air cells, that contain disinfection fluid improves the efficiency of the maf"l to filter, and adsorbs tiny particles. Therefore, clean air is getting to the nose all of the time of the usage. The disinfection fluid destroy the viruses and microbes that trapped. The separation between the nose and the mouth (5), and the sealing of the nose (2), reduces the passage of the air to the glasses that wear the maf"l (1) user, therefor it prevents mostly, fog forming on the glasses with breathing. When stretchy straps are in used, we can use 2 buckles (12) and (13), instead of ties (7) and (8). Then first we fix the length and then we put a buckle. It is also possible to not use buckles, first we fix the length and then make a steady tie, when we will wear the maf"l (1) the strap will be stretched. In this case the strap (4) must be wear before the strap (3). 23) When using 2 buckles there in no difference.

24) People that need to clean there mouth can use maf"l with one strap.

25) In public places where it not sure that the usual masks are efficient or vanished the maf"l will be given free.

For maf"l kind nose and mouth enlarged, with one strap, as described in fig. 3 and 10:

1) For people that can not wear maf"l (1), it will be manufactured a nose and mouth enlarged maf"l (11). That has 4 holes for the upper strap, that made of a sheet of material of foamed plastic, spongy and flexible, that contain tiny air cells in kind of open cells that let air pass through it, it protects of the nose, mouth and a part of the cheeks.

2) The maf"l (11) has one upper strap that is the same the one upper strap in the maf"l (1) and all way of wearing is the same.

3) Except maf"l (11) do not have lower strap all the description in maf"l (1) is the same.

4) The lower part (21) of the maf"l (11) is bended up with the user finger (20) for he can cleaning the mouth and drink water from a bottle (20), at the end it get down and protect of the mouth, while drinking the excellent sealing in the nostrils remains.

For maf"l kind nose and mouth, with one strap, as described in fig. 6-8:

1) For people that can not wear maf"l (11), it will be manufactured a nose and mouth maf"l (27) ,that has 2 holes for the upper strap. That made of a sheet of material of foamed plastic, spongy and flexible, that contain tiny air cells in kind of open cells that let air pass through it, it protects of the nose and mouth.

2) The maf"l (27) has one upper strap that is the same the one upper strap in the maf"l (1) and all way of wearing is the same.

3) But the one upper strap (3) will be laced in just in 2 upper holes (39) it has.

4) The maf"l (27) will continue to protect the nose because the excellent sealing in the nostrils remains.

5) Except maf"l (27) do not have lower strap and just 2 holes, all the description in maf"l (1) is the same.
