Abstract

<P>PROBLEM TO BE SOLVED: To provide a mask comfortably put on a healthy person during work or study or on the way to work in view of problems in a conventional mask which sucks particles such as pollen, dust and exhaust gas due to a poor sealing method, resulting in feeling hot in the face and stifling besides the mask being hard and ugly. <P>SOLUTION: This mask is provided with a collar at the inside upper part of a mask body to limit a sealing range of the mask only around the nose. A vertical rising wall is thereby formed to change a square mask into a three-dimensional mask, and the upper part of the mask is sealed. As to lower sealing, a part under the nose and cheeks are covered with a lower turn-up with a sealing material put inside, which is held down by the mask body to seal. The nasal mask is further provided with a filtering function part and an exhaust function part by attaching a nose pad cloth to the mask. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mask that mainly covers a nose portion, prevents fine particles such as pollen, dust, exhaust gas, etc. from entering a nostril, and enables a worker to work, study, and do housework normally while using the mask. Things.

As a general mask, there is a sheet-shaped mask having ear straps on both the left and right sides and a bendable wire inserted at the upper end of the mask. When the mask is worn, the mask body is bent in an arc shape at the nose, and triangular gaps are formed on both sides of the nose as shown in FIG. For this reason, a wire is inserted in the upper part of the mask to seal the gap along the shape of the face. However, when speaking or moving the mouth, the mask moves or the mask is wider than the ear width, so that both ends of the mask are deformed into an arc shape, and the outside air flows through the gap. Furthermore, although the nostrils face downward as shown in FIG. 22, since the mask is substantially parallel, it is not exhausted through the mask, so that expiration is easily trapped inside and breathing is difficult. Another drawback was that the heat from the mouth and nose lit the face and made it uncomfortable. FIG. 20 shows a sanitary mask disclosed in Japanese Patent Application Laid-Open No. Hei 10-5360 (Japanese Patent Application No. Hei 8-159404) as an improved seal method using a wire. In this mask, the upper part of the mask body is folded twice, a wire 53 is inserted into the tip of the outer bag 52, and both sides are sewn to form a bag. At the time of wearing, when the double bag is simultaneously turned up and put on the nose, the terminal of the inner bag 51 becomes insufficient in length by the amount of the turn, so that the mask body is curved as shown in FIG. Creates a triangular gap that has been pulled together. In order to fill this gap, the outer bag 52 is turned up, a vertical wall is formed so that the curtain is lowered from above, the wire at the tip is pressed, and the shape is fitted to the face and sealed. Regarding the lower part of the mask, the bag-shaped folded back 54 is turned up and applied to the chin to seal the lower part. In this mask, since the seal body is pressed by the mask body and positioned by the jaws, the mask does not move, the gap is reduced, and the sealing property is improved, but the above-mentioned drawbacks remain. In order to seal the triangular gap with a molded product, there is a mask at the upper end of a commercially available mask as shown in FIG. 23, which allows a sponge molded product to be removed. In this method, since the sponge is pressed from above by the mask body, there is no leakage to the upper part, but there is a step in the thickness of the sponge on the side of the mask, and leakage occurs from the side. And it takes time and effort to form the sponge, and the cost is high.

Masks that wrap only the nose include (1) those that forcibly deliver oxygen for medical use and (2)
A piece with a piece in the nostrils and gauze or non-woven fabric in the piece There is a set nasal mask. Since (1), (2) and (3) have little relevance to the present invention, they are excluded from the object, and the mask of Japanese Utility Model Registration No. 3076663 (Japanese Patent Application No. 2000-7002) shown in FIG. There is. This mask is provided with a breath blocking section 72 at the upper end of the nose cover section 71, and a moist gauze is applied to the nose, and this is held down by the nose cover section 71. It is unknown, but it seems that the lace fabric was sewn with a straight line at the top. Since the top of the mask is sewn in a straight line, it is difficult to seal the triangular gap with a height of approximately 12 mm by simply turning over the lace cloth on the upper side and only riding on the nose in a plate shape. Furthermore, since there is no seal at the lower part, exhaled air leaks from the lower part with a narrow nasal mask. The mask of Japanese Patent Application Laid-Open No. 2000-322 (Japanese Patent Application No. 10-168495) shown in FIG. 25 is provided with a bag-shaped nose hook 82 in which the upper portion of the mask body is folded inward and both sides are sewn, and the bag is turned up at the time of wearing. There is a mask that covers the nose. As described above, this mask has a triangular gap shown in FIG. 21 and cannot seal the upper portion. Some of the same applications cover the nostrils shown in FIG. In this method, a nose hook portion 82 and a nose closing portion 83 are provided inside the mask body, and both sides are sewn up to turn over the upper and lower bags to seal the nose and the nostrils. This mask is a good method of breathing through gauze, since the sealing effect of the nose hook portion is not the same as described above, but the nose blocking portion 83 seals with the force of pulling up the nostril surface. However, the nasal obstruction is too close to the nostrils, making it difficult to breathe when a gauze is applied. In addition, there is a drawback that the portion covering the nose and the nostrils protrudes outside and is unsightly.

Regarding the ear strap, there is a mask provided with two ear straps in Utility Model Registration No. 3089472 (Japanese Utility Model Application No. 2002-2279) in FIG. This is provided with an ear hook upper string 91 at the upper end of a conventional ear hook main string 92. At the time of wearing, the main string and the upper string are put on the ears, and when the masked person blows the nose, the main string is removed and the nose is blown with the mask attached. There is also a type in which an ear hook lower string 93 is provided instead of the ear hook upper string as shown by a dotted line, but the usability is the same as the above.

Currently, the mainstream shown in Fig. 21 for sealing the gap formed beside the nostril is supported by inserting a deformable wire, but the mask moves during conversation or the gap is increased by being pulled on both sides. However, the sealing method is not perfect. In a method in which a bag is provided inside the mask and the bag is turned up and sealed, the gap cannot be sealed even if the mask is deformed. As described above, a method of using the mask body to seal the gap beside the nostril has not yet been established.

In the current rectangular mask, since the nostrils and the mask body are almost parallel, the expiratory breath is not discharged through the mask, but is discharged from the mask terminal, and the inhalation is also inhaled from the mask terminal. bad. And the breath without energy is stuffed in the mask and breathless. In addition, heat from the nose and mouth heats up the inside of the mask, causing the face to burn and reduce thinking ability. Then, even when the mask is taken, the feeling of masking the face remains unpleasant.

The paper and non-woven masks are made of hard material, so they hit the protruding part of the face and do not fit the face. The gauze cloth is the best material to cover the unevenness of the face smoothly. However, the current mask has a thick mask body (approximately 16 folds) and a germicidal sheet and the like, so that it has a hard plate shape. As a result, the properties of gauze cloth are not being used.

In the current nasal mask, the seal parts and the folded bag protrude outside the mask, and the appearance is poor. Also in the mask covering the nose and the mouth, the mask body is pulled up and down by the ear hanging string, and the mask body is rounded up and down, and the outside air enters from the side due to wrinkles. Then, there was a problem that the appearance was poor.

The purpose of wearing a mask is, firstly, that a person who has a cold does not spread the cold. To prevent sneezing, coughing, and splashing of saliva during conversation, and to prevent drying of the nostrils and to prevent worsening of symptoms. The second is to prevent healthy people from inhaling pollen, sputum, exhaust gas and smoke. Considering the mask used by healthy people, when they are active, they breathe in their nose and their mouths are closed. When you speak, you only exhale, not inhale. Therefore, the mask for the purpose of prevention does not need to be sealed to the mouth, and if only the nose is used, it is possible to talk, eat, smoke, and smoke. It has been considered that the above-mentioned object can be achieved even in a mask for a person suffering from a cold by attaching a mouth cover under the nasal mask by extending the nasal mask.

To improve the sealing of the square mask that covers the nose with ear straps on both sides, an exhaust port is provided in the center of the nose mask, the mask body presses the upper and lower seal parts of the nose from above, and the seal shape is changed to the unevenness of the face By attaching, it is possible to prevent the invasion of outside air and to seal around the nose. And, in a wide mask that covers the nose and mouth, a mouth cover is provided under the nose mask, and two ear straps with a reduced width are simultaneously wrapped to prevent deformation of the mask, Creates a mask that adheres to the face. First of all, in order to eliminate the triangular gap formed beside the nostril, an eaves that is not fixed to the mask body was provided under the bag that turns over the inside of the mask. As shown in FIG. 2, a sealing material having elasticity and rigidity is provided on the upper folded part 2 which is folded inside the mask with a dimension obtained by adding the length of the eaves 8 to the height of the nose x from the place several mm below the upper end. Insert 9 and sew the outer circumference of the mask body. Then, when the upper side of the folded back is sewn with the substantially horizontal cross-sectional shape (6) of the face, cuts 7 are made at both ends of the eaves 8 formed below the sewing line, and eaves 8 not fixed to the mask body are provided. If the sewn shape is straight, only the eaves will be turned over and there is no sealability, but if sewn with the horizontal cross-sectional shape of the face, it will be transformed into a three-dimensional shape along the face, and the resilience of the built-in seal material will turn the nostril side I made a vertical standing wall and thought that the eaves under the standing wall would stick to the face and seal the gap. For example, the tip of a triangle connecting the apex d of the nose and the cheeks e and f shown in FIG. 15 is sewn as shown in FIG. 2 with a line a cut at the height x of the nose as shown in FIG. When the eaves 8 with cuts 7 at both ends of the eaves 8 are turned over and attached to the face, the mask body 1 is deformed into a curved surface passing def, and the chevron sewing line 6 becomes a straight line as shown in FIG. Then, as shown in FIG. 18, the eaves 8 stand vertically, and the terminals of the eaves 8 are compressed and waved. The horizontal portion 5 covers the R portion of the nose, and the swirling of the height of the nose x creates a vertical wall along the nose, closes the gap beside the nostril shown in FIG. Free eaves 8 that are not fixed will seal your face. This seal is pressed from above by the mask body 1 to close the gap above the mask. The seal at the lower part of the mask covers the lower part of the nose and the cheek with a width of about 1/3 from the lower end of the mask and about half the thickness of the nostrils, and the mask body 1 presses the above from above to close the gap. Then, the sealing material to be put into the lower folded part is divided into three pieces and the terminals are overlapped (FIG. 4), so that the mating part comes to the depression line where the arc of the lower nose and the upper jaw and the line of the cheek intersect (FIG. 15). It was thought that the sealing performance would be further improved by setting. If the sewing line of the upper folded part 2 is set to be approximately 1/3 of the mask width from the upper end, the folded eaves do not protrude from the mask body, and the exhaust port is formed in the center of the mask body. Finally, for the masks on the left and right sides, make the total length of the mask longer than the face width (130 mm) and seal it on the side of the face. Then, if the thickness of the bent portion is reduced by making the built-in sealing material a face width, the mask body follows the face and there is no gap. In addition, the wide mask that covers the nose and mouth can be divided into two pieces of ear straps, which can be worn around the ears at the same time to prevent deformation of the mask, eliminating gaps on both sides, and closing the gaps. Can be done.

Regarding the breathlessness of the mask, it is necessary to know the process of exhalation. As for the exhalation, at first, a large-volume and expiratory exhalation (about 2/3) is exhaled at a stretch, and then, an exhaled exhalation (about 1/3) is exhaled slowly. This breathless breath cannot be exhaled, making it difficult to breathe. In order to discharge the breathless breath, the mask main body was brought close to the nostril at a right angle and a thin discharge function part was provided to increase the internal pressure to facilitate discharge. In order to set up the mask, an elastic sealing material made of nylon was placed inside the eave, and the vertical wall was made with the restoring force when the eave was turned over. In order to facilitate exhalation, the fold of the main body is made eight-fold, and when turning over the eaves, the exhaust port is made four-fold thin. A space 14a (FIG. 8) through which exhaled air is passed is provided between the nose rugs by sandwiching the garment 14 between the lower folded portions 3 (approximately half the thickness of the nostrils), so that the exhaled breath is exhausted from the exhaust function unit. I made it. When this mask is worn and breathing, first, a large amount of expiratory breath and inhaled air are sucked and exhausted through a filtering function part composed of the nose pad cloth 14 and the mask body 1 in contact with the nostrils. As shown in FIG. 19, the air flows laterally against the wall of the lower turnback 3 (approximately half the thickness of the nostril) and is exhausted from the exhaust ports of the mask body 1 on both sides. The width of the exhaust port was reduced to approximately 1/3 of the mask width, and the internal pressure was instantaneously increased to facilitate discharge. Certainly, if the mask body is thin, it seems that the filtering function of the mask is lost. However, since it can be adjusted by the thickness of the nose pad and the air can be sucked and exhausted through the mask, the filtering function is considered to be improved as compared with the conventional mask.

To make the mask as soft as its feathers and you don't know what you're wearing, the mask body has been thinned to make it easier to fit on your face. Then, in order to wrap the skin gently, a ribbon planted on both sides of the sealing material was used to softly wrap the unevenness of the face. Then, in order to bring out the softness of the entire mask, the lower seal material was not sewn to the main body but was floated in the air without being sewn to the main body, and the lower nose and the cheek were covered like a floating bag.

To improve the appearance of the nasal mask, the eaves were placed inside the mask terminal so that the turned eaves did not protrude outside. Then, the eaves sewn shape was selected as the line a in FIG. 15 so that the mask body drawn a beautiful arc. Originally, if sewn in line b, the mask body conforms to the shape of the face and reduces the gap, but it was not adopted because the sides of the nose were dent and unsightly.

As a measure to prevent the face from burning, limit the air intake / exhaust opening only around the nose, and open or loosen the mouth cover to prevent heat and exhalation from the mouth from being trapped in the mask. Can be released. For this reason, the ear strap is divided into upper and lower ear straps (Fig. 12), an intermediate hole is drilled on the side of the mask so that the length can be easily adjusted, and one ear strap is passed through the figure 8 ( A mask provided with a center string (FIG. 14) in which the ear strap was pulled out from the intermediate hole and an ear strap was provided.

The nasal mask of the present invention is configured as described above.First of all, the mask body presses the eaves standing wall and the lower folded back seal portion and securely seals a narrow area, so that it passes through the mask. No more breathing outside air and no exhalation leaks. Furthermore, the area covered is limited to the nose only, and the seal area is narrowed, so that the face is no longer hot. Secondly, the exhaust port of the mask body is thinned so that it can be easily exhausted, and divided into a filtering function section and an exhaust function section with a nose pad cloth. With no exhalation, I was able to get out of both sides of the mask, so I didn't have any suffocation and didn't bother me at work. Rather, the nose is warm enough to boost your energy and focus on your work. Third, using a gauze cloth and flocking ribbon that is gentle on the skin as the material, the mask body was thinned, sewing was not performed, and rigid parts were eliminated, resulting in a comfortable mask that gently wraps the face. And the appearance, beautiful curves and squares were maintained, and it was no longer embarrassing to put it on the train. To sum up, in the opinion of a person with hay fever, when there is pollen in the house and there is no help for nose, it stops as soon as you put on a mask. And, while wearing a nose mask, they can see the taste of the dishes, talk, and eat, which is very convenient. In this way, a healthy person can easily wear it, and a simple rectangular mask has been replaced with a three-dimensional mask, and the cost has become meaningful. The mask that covers the nose and mouth also has the effect of the nose mask, and the use of a plurality of ear straps eliminates gaps. I was able to make a mask.

Embodiment 1 FIG. 1 shows a nasal mask main body 1, in which a gauze cloth is folded as shown in FIG. 9 and an upper seal material 9 and a lower seal material 10 are put inside, thereby forming a folded main body shown in FIG. A side-contact ribbon 11 is attached to the folded body, and the outer periphery 4 of the mask body is sewn as shown in FIG. Then, a horizontal sewing line 5 and a mountain-shaped sewing line 6 are sewn from a place several mm below the upper side to form an eave 8, and both sides of the eave are vertically cut 7 and a nose mask is completed through an ear hook upper string 13-1. I do. To explain the details in detail, a 130 mm long lower sealing material 10 in which three ends of three 1.6 mm thick, 6 mm wide ribbons, each of which has been flocked on both sides, are superimposed at 20 mm on each side is inserted into portion 2a in FIG. When it is rolled up four times, the lower folded part 3 is made. In FIG. 9, the upper folded portion 2 is formed by folding the upper sealing material 9 having a thickness of 1.6 mm, a width of 24 mm, and a length of 130 mm into a portion c folded in the dimension b, and winding it in the dimension c to form an upper folded portion 33 mm from the upper end. . On both sides of the main body shown in FIG. 10 consisting of the upper folded back 2 and the lower folded back 3, a side-applied 0.6 mm thick, 24 mm wide, 48 mm long side-applied ribbon 11 is attached to the main body, and a 48 mm wide, 160 mm long mask body set product Can be done. When sewing the outer periphery 4 of the set product shown in FIG. 2, the lower seal material 10 and the upper seal material 9 are adjusted so that the positions are not sewn into the mask body 1 and then sewn, and a place approximately 10 mm lower than the upper end of the mask. The seal material and the mask body are sewn on the horizontal sewing line 5 and the chevron sewing line 6 to form an eaves sewing line. If the both ends of the bag formed below the sewing line are cut 7 mm vertically 7 mm, an eave 8 is formed and the mask body 1 is completed. The nasal mask is completed by passing the ear hook upper string 13-1 on both sides of the mask body 1. The nose pad cloth 14 shown in Fig. 5 to be inserted into this mask, when the gauze cloth folded in half is folded vertically into three pieces, the upper edge is sewn with a difference of 5mm at the terminal, 55mm long, 33mm in height and 28mm below opening A nose pad 14 is formed.

When mounting this mask, first, when turning both ends of the eaves 8 shown in FIG. 7, a quadruple exhaust port appears in the center of the mask, and a bag of the lower folded back 3 appears below it. The nose pad 14 is inserted into the folded bag, the nose is applied to the upper end of the nose pad, and the upper ear strap 13-1 is applied to both ears so as to cover the nostrils. When the mask body is swung to the left and right to make the angle line straight (Fig. 16), the eaves with the height of the nose x create a vertical wall on the cheek, and the free eaves adhere to the face and seal the top, A lower fold 3 that is half the thickness of the nostril seals under the nose. Then, both sides of the mask are broken by the cheekbones to seal the sides, and the periphery of the nose is sealed. To check the exhaust status, we checked the flow with cigarette smoke. A large amount of energetic smoke was exhausted from the center of the mask body, and the weak smoke was slowly released like steam from both sides of the mask after a while. Smoke from both sides slightly clouded the outside of the glasses, but there was no breathing difficulty or air leakage. Then, the appearance of the mask was such that a beautiful square curved surface was formed and the appearance was improved.

Example 2 The mask that covers the nose and mouth shown in FIG. 12 covers the nose and mouth by folding four times as shown in FIG. 9 at 57 mm obtained by adding the length of the folded back portion of the nose mask 15 mm and the cover 42 mm to the mouth as shown in FIG. 9. I made a mask set. On both sides of this set, attach a side-contact ribbon 11 of 0.6 mm thickness, 24 mm width and 90 mm length with double-sided tape 12, and make a cut (intermediate hole 16) through the ear hanging string 45 mm from the upper end of the ribbon. A 90mm wide, 160mm long mask body was made. After the outer periphery of the mask body is sewn on the outer peripheral sewing line 4 shown in FIG. 12 by adding a mouth cover to the outer peripheral sewing line of the nasal mask, a horizontal sewing line 5 on the upper side of the eaves and a chevron like the nasal mask The mask body 1 is made by sewing the sewing line 6 and cutting 7 on both sides of the bag. A mask for covering the nose and mouth with the upper ear strap 13-1 and the lower ear strap 13-2 by passing an ear strap through the middle hole from the upper end and a figure eight through the middle hole from the lower end. Is completed. A mask with an open mouth cover is completed by shortening the ear-hook lower string 13-2 as shown by a dotted line and putting only the ear-hook upper string 13-1 on the ear. In the mask provided with the central ear strap 13-3 shown in FIG. 14, the central ear strap 13-3 is formed when the ear strap is passed from the upper end to the lower end and the ear strap is pulled out from the intermediate cord hole 16.

This mask is worn in the same manner as the above-mentioned nose mask by turning over the eaves, sandwiching the nose pad 14 at the lower part, covering the nostrils by applying the nose to the upper end of the nose pad, and placing the upper and lower ear straps 13-1 and 13-1. Hang the lower string 13-2 on both ears. Then, holding both sides of the mask and straightening the chevron sewing line 6, the eaves make a wall and seal the nose three-dimensionally. The lower mouth covering part covers the mouth along the face, Despite having disappeared, the exhaust was exhausted from the thin mouth cover, so there was no heat and no stuffiness. The only concerns were a slight sweat on the nose and a slight movement around the mouth during the conversation. Then, there was no gap in which the entire mask moved or deformed into an R shape, and a good-looking mask was obtained. And because it became a refreshing mask, it was natural to wear a mask when going out.
