Description

  The present invention relates to a mask effective for anti-virus and anti-hay fever measures in daily life, and more particularly, to a mask with low breath resistance and high fashionability.

  In order to prevent viruses that are transmitted through humans, masks are used to protect people when going out to crowded places in winter or when a whistle occurs. In addition, a mask may be worn to prevent hay fever caused by sucking cedar pollen that frequently occurs in spring.

  Conventionally used masks are often used with a non-woven fabric in order to be disposable. Although this non-woven fabric mask can be manufactured at low cost, it has a single color, white, light blue, light pink, and the like, and only the color of the material itself appears on the surface. For this reason, although it was practical, the faces of the people who used it were covered with a mask of the same color, it was monotonous rather than individual. If the mask covering most of the face was monochromatic, all people had the same face, making it difficult to distinguish a particular person.

  In addition, there is no room for selection of mask colors, and only the monotonous monochromatic colors described above were available. Then, the clothes of the person using the mask and the color of the mask are unbalanced, and the appearance is deteriorated. In the case of a woman, for example, the color of the coat, the color of the pattern and the skirt, and the pattern are usually selected so that the combination is good. However, since there is no room to select the color and pattern of the mask, there was a slight feeling between the mask and the clothes. For this reason, there has been a demand for a rich variety of mask colors and patterns that can be selected according to the color and pattern of clothing.

  And in the nonwoven fabric used for a mask, when it was going to collect virus and pollen efficiently, the thickness of the nonwoven fabric increased and it was difficult to breathe. In order to facilitate breathing, the thickness of the nonwoven fabric has to be reduced, making it difficult to reliably collect viruses and pollen. The thickness of the non-woven fabric was contradictory to improve the effect and usability.

  In this way, in the conventional masks available in the city, since the non-woven fabric is manufactured in a form that is exposed to the outside as it is, the color and pattern are simple and monochromatic, It was far from fashion.

  For young women who are interested in clothes on a daily basis, the narrow selection of colors and patterns for masks covering most of the face is inconvenient because it cannot be matched with the clothes.

  Moreover, in order to collect viruses, pollen, etc. with a non-woven fabric, the non-woven fabric must be thickened. However, when the effect is enhanced, it has the contradictory performance of making it difficult to breathe.

  In the present invention, a cloth mask cover is brought into close contact with a filter using a non-woven fabric, and a large number of colors and patterns of the mask cover are prepared, so that the consistency with the clothes is improved and the balance of the masked appearance is improved. The purpose is that.

  Another object of the present invention is to attach a valve mechanism to the mask separately from the filter, so that the breathing load is reduced by preventing the filter from passing through during expiration.

  The present invention uses a flat fabric as a material, a mask cover that can cover at least the mouth and nose of the face, a filter that is interposed between the mask cover and the face and collects viruses and pollen, and a mask cover. And a valve mechanism that is attached to a portion and is closed when inhaling and opened during exhalation to allow the breath to flow only in one direction. .

  The present invention uses a flat fabric as a material, a mask cover that can cover at least the mouth and nose of the face, a filter that is interposed between the mask cover and the face and collects viruses and pollen, and the nose of the mask cover A pair of valve holes opened to the left and right positions centered on the filter, a pair of valve holes opened to the left and right positions centered on the filter nose, and the valve holes of the mask cover and filter, The present invention provides a mask characterized by comprising a pair of valve mechanisms that are closed at the time and opened at the time of exhalation to allow the breath to flow only in one direction.

  In the present invention, the mask cover is composed of two right and left fabrics, the filter is composed of two left and right nonwoven fabrics, and the opposing edges of the mask cover fabric pieces and the filter nonwoven fabric pieces are arcuate in opposite directions. The opposite edges of the right mask cover fabric piece and the left mask cover fabric piece are stitched together, and the opposite edges of the right filter nonwoven piece and the left filter nonwoven piece are welded together, The present invention provides a mask characterized in that the filter is formed into a three-dimensional shape like a nose when the filter is expanded to the left and right.

  The present invention provides a mask characterized in that the filter is formed by superposing at least four nonwoven fabrics having different functions.

  The present invention provides a mask characterized in that a nose fitter capable of maintaining the shape of the filter by deforming the back surface of the filter so as to be in close contact with the surface of the nose is fixed to the upper part of the front surface of the filter. .

  In the present invention, the valve mechanism is provided with an opening through which air can flow in front and rear, a valve seat is provided around the opening, and a valve membrane that controls the flow of air by contacting and separating from the valve seat is detachable. The present invention provides a mask characterized in that the mask is arranged in the above.

  With the mask of the present invention, the mask cover that appears on the face of the face is made of fabric, so you can express various designs and colors on the surface, and select the clothing design, the design that matches the design, and the color mask Can be used.

  Since the mask mechanism of the present invention is provided with a valve mechanism, the breath can be discharged smoothly when exhaling, and it is not stuffy and does not place a burden on the human body.

  Hereinafter, an embodiment of a mask according to the present invention will be described with reference to the drawings.

  1 to 11 show a first embodiment of the present invention. FIG. 1 shows a state in which the human body is protected from viruses, pollen, dust and the like by wearing the mask 11 of the present invention. The mask 11 is made of a flexible cloth material and is mounted so as to cover most of the cheek B from the nose C to the chin. Ear straps 23 are attached to both sides of the mask 11, and the ear straps 23 are U-shaped and are hung on the ears D on both sides so that the entire mask 11 does not fall off the cheek B. Valve mechanisms 14 and 15 are attached to the left and right sides of the front surface of the mask 11, and the valve mechanisms 14 and 15 open only when exhaling, and are closed when inhaling. Sometimes it does not burden the lungs.

  Since the front side of the mask 11 is a flexible piece of cloth, it is possible to select and use cloths printed on various designs or dyed in various colors. Instead of a single color or plain color as in the past, the design and color can be freely expressed on the front side of the mask 11. For this reason, if many kinds of patterns and colors of the mask 11 are prepared, it is possible to select a pattern and colors that match the clothes of the person wearing the mask 11.

  FIG. 2 shows the components constituting the mask 11 separately. The mask 11 is roughly composed of the mask cover 12, the filter 13, the valve mechanisms 14 and 15, and the caps 16 and 17. A cloth piece is used for the surface of the mask cover 12, and the back side of the mask cover 12 has a double structure in which a mesh piece having a rough mesh is in close contact. When the mask 11 is worn, the mesh piece comes into close contact with the skin. . With a flat piece of cloth, sweat may get wet between the piece of cloth and the skin and become uncomfortable. However, by interposing the mesh piece between the cloth piece and the skin, the skin can be dried without staying sweat, so that a refreshing feeling can be maintained. Both ends of the ear straps 23 and 24 are connected to the left and right side surfaces of the mask cover 12, respectively, and an adjuster 25 for adjusting the length is inserted in the middle of the ear strap 23. A ring 27 is inserted in the rear part. Similarly, an adjuster 26 for adjusting the length is inserted in the middle of the ear strap 24, and a ring 28 is inserted in the rear part of the adjuster 26.

  Next, a filter 13 that collects viruses, pollen, dust, and the like is located on the back surface of the mask cover 12 (the inner surface that is in close contact with the skin in the mounted state). Vent holes 29 and 30 are opened on the lower left and right. The filter 13 is formed by laminating a plurality of layers of non-woven fabric, and has a high ability to collect viruses, pollen, dust, and the like, and has a high moisturizing performance.

  The valve mechanisms 14 and 15 incorporate a valve capable of controlling the flow of air, and operate so as to be closed during inhalation and open during exhalation. The valve mechanism 14 is inserted into the vent holes 21 and 29, and the valve mechanism 14 is fixed to the mask cover 12 by engaging the cap 16 with the valve mechanism 14 from the back side of the filter 13. Similarly, the valve mechanism 15 is inserted into the vent holes 22 and 30, and the valve mechanism 15 is fixed to the mask cover 12 by engaging the cap 17 with the valve mechanism 14 from the back side of the filter 13.

  3 and 4 illustrate a procedure for assembling the mask cover 12 shown in FIG. 2 from members.

  As shown in FIG. 3, the members constituting the mask cover 12 are formed by cutting pieces of four fabrics, a right front cloth 35, a left front cloth 36, a right mesh cloth 37, and a left mesh cloth 38. The right front cloth 35 and the left front cloth 36 are respectively positioned on the surface of the mask 11 and are made of flat materials such as plain weave of rayon or polyester. The right mesh cloth 37 and the left mesh cloth 38 are respectively located on the back side of the mask 11, and are made of a material woven with rough eyes such as polyester and having a thick waist. Has a large space and good air flow.

  The right front cloth 35 and the right mesh cloth 37 have the same shape, and the left front cloth 36 and the left mesh cloth 38 have the same shape. The right front cloth 35 and the left front cloth 36 are reversed symmetrical, and the right mesh cloth 37 and the left mesh cloth 38 are reversed symmetrical. That is, the four pieces of cloth have the same shape and are different depending on whether they are reversed left and right. For this reason, the shape of the right front cloth 35 will be described, and the shapes of the other cloth pieces will be omitted.

  A nose line 39 curved in a bow shape is formed on the nose side of the right front cloth 35, that is, on the left side in FIG. 3, and an upper line 41 having a curved line that gently falls from left to right on the upper side of the right front cloth 35. Is formed on the right side of the right front cloth 35 and slightly curved inward (leftward) from the upper side to the lower side. On the lower side of the right front cloth 35, the right side to the right side are formed. A straight lower line 45 that is inclined so as to be slightly lifted toward is formed. The nose line 39, the upper line 41, the ear line 43, and the lower line 45 form a deformed quadrilateral that is somewhat like a rhombus. Further, a valve hole 47 is opened at a position displaced obliquely downward from the center of the right front cloth 35, and eyelet holes 49 and 50 are opened at positions above and below the ear line 43. The valve hole 47 is for inserting the valve mechanism 14 and is relatively large, and the eyelet holes 49 and 50 are for inserting eyelets and are relatively small.

  The left front cloth 36 has the shape of the right and left objects and the right front cloth 35, and the nose line 40, the upper line 42, the ear line 44, the lower line 46, the valve hole 48, and the eyelet holes 51 and 52 are formed in the same manner as the left front cloth 36. Has been.

  The right mesh cloth 37 has the same shape as the right front cloth 35, and similarly to the right front cloth 35, a nose line 55, an upper line 57, an ear line 59, a lower line 61, a valve hole 63, and eyelet holes 65 and 66 are formed. Has been.

  The left mesh cloth 38 has a shape that is the same as that of the right mesh cloth 37. Like the right mesh cloth 37, the nose line 56, the upper line 58, the ear line 60, the lower line 62, the valve hole 64, and the eyelet holes 67, 68 are used. Are formed respectively.

  In order to sew these four pieces of cloth, the right front cloth 35 is overlapped on the surface of the right mesh cloth 37, the left front cloth 36 is overlapped on the surface of the left mesh cloth 38, and the nose lines 39, 40, 55 and 56 are curved. Suture along. The stitched portion becomes a seam 76, and the shape of the human body's nose is hidden. Since each cloth piece has the same shape or the shape of the left and right, the valve holes 47 and 63 coincide, the valve holes 48 and 64 coincide, and the eyelet holes 49 and 65, 50 and 66, 51 and 67, 52 And 68 are the same position. In this state, the eyelet 71 is inserted into the eyelet holes 49 and 65, the eyelet 72 is inserted into the eyelet holes 50 and 66, the eyelet 73 is inserted into the eyelet holes 51 and 67, and the eyelet 74 is inserted into the eyelet holes 52 and 68, respectively. Secure with. By doing so, the right front cloth 35 and the right mesh cloth 37 are polymerized, the left front cloth 36 and the left mesh cloth 38 are polymerized, and the four cloth pieces are integrally formed.

  The state assembled in this way is indicated by (•) in FIG. Since the curved nose lines 39, 40, 55, and 56 are stitched together at the seam 76, they are flat when folded, but when the sides of the ear lines 43 and 44 are opened to the left and right, the nose lines 39, 40, 55 , And rises three-dimensionally along the curve 56, and has a shape with the center rising as indicated by (•) in FIG. In this shape, it becomes the shape of the face of the human body and can be closely attached to the cheek while hiding the nose and mouth.

  Further, in order to complete the semi-finished product as shown in FIG. 3 (•) as the mask cover 12, the hooking straps 23 and 24 must be trimmed, and the process will be described with reference to FIG.

  In FIG. 4, the semi-finished product of the mask cover 12 shown in FIG.

  First, an edge cloth is sewed around the semi-finished product, so that the periphery of the four pieces of cloth is not exposed and the whole is given strength.

  The upper edge cloth 81 obtained by cutting a flexible cloth into a belt shape is covered with the edges of the upper lines 41, 42, 57, and 58 of the right front cloth 35, the left front cloth 36, the right mesh cloth 37, and the left mesh cloth 38 described above. The edging is performed by stitching the upper edge fabric 81 from the upper and lower sides. Similarly, the lower lines 45, 46, 61, and 62 are covered by folding a lower edge cloth 84 obtained by cutting a flexible cloth into a band shape and stitching the upper edge cloth 84 on the front and back. Further, the edge of the ear lines 43 and 59 is covered with a right edge cloth 82 obtained by bending a flexible cloth into a band shape and stitched from the upper side of the right edge cloth 82 to the front and back. Further, a left edge cloth 83 obtained by cutting a flexible cloth into a belt shape is folded and covered on the edges of the ear lines 44 and 60, and the left edge cloth 83 is sewn on the front and back sides to be trimmed. By bordering in this manner, the upper edge cloth 81, the right edge cloth 82, the left edge cloth 83, and the lower edge cloth 84 are surrounded around the right front cloth 35, the left front cloth 36, the right mesh cloth 37, and the left mesh cloth 38. It is sewn and formed integrally so that the four pieces of cloth are not peeled off at the same time.

  Next, one end of the ear strap 23 is inserted into the eyelet 71, and one end of the ear strap 23 is tied to the knot 86 on the back side of the right mesh cloth 37. Next, the other end of the ear strap 23 is inserted into the eyelet 72, and the other end of the ear strap 23 is tied to the knot 87 on the back side of the right mesh cloth 37. One end of the ear strap 24 is inserted into the eyelet 73, and one end of the ear strap 24 is tied to the knot 88 on the back side of the left mesh cloth 38. Further, the other end of the ear strap 24 is inserted into the eyelet 74, and the other end of the ear strap 24 is tied to the knot 89 on the back side of the left mesh cloth 38. These knots 86, 87, 88, 89 prevent the left and right ear straps 23, 24 from falling off the eyelets 71, 72, 73, 74. The state in which the ear strap 24 is tied so that the ear strap 24 does not come off from the eyelet 73 is shown in a circular enlarged view in FIG.

  FIG. 5 illustrates a procedure for assembling the filter 13 in FIG. 2 from a material.

  The filter 13 includes three members: a right filter piece 91, a left filter piece 92, and a nose fitter 93. Since the right filter piece 91 and the left filter piece 92 have symmetrical shapes in which left and right are reversed and have the same shape, the shape of the right filter piece 91 will be described, and the left filter piece 92 will be omitted.

  A nose line 96 having a circular arc shape is formed on the nose side (left side in FIG. 5) of the right filter piece 91, and a slightly straight upper line 98 inclined from the left to the right is formed on the upper side. The ear line (right side in FIG. 5) of the filter piece 91 is formed with an ear line 100 that is slightly straight from the upper side to the lower side, and the lower line 102 that is slightly straight and inclined from the left to the right on the lower side. Is formed. The junction between the upper line 98 and the ear line 100 and the junction between the ear line 100 and the lower line 102 are rounded, and the entire right filter piece 91 has a scale-like quadrilateral shape. A valve hole 104 is opened at a position slightly displaced from the center of the right filter piece 91 to the left.

  The left filter piece 92 has a left / right target shape with respect to the right filter piece 91, and a nose line 97, an upper line 99, an ear line 101, and a lower line 103 are formed around the left filter piece 92, and the valve hole 105 is opened It is.

  The nose fitter 93 is formed of a material that can be deformed with some force and maintain the deformed shape using a material such as aluminum or hard resin.

  In order to assemble the filter 13 from these three members, the nose lines 96 and 97 of the right filter piece 91 and the left filter piece 92 are combined, and the edges of both are fixed by heat sealing. Then, the nose lines 96 and 97 are continuously joined by fusion, and become the joining line 107, and the right filter piece 91 and the left filter piece 92 are integrated. A nose fitter 93 is disposed between the front upper portions of the right filter piece 91 and the left filter piece 92, and both ends of the nose fitter 93 are fixed by heat-sealing to the surfaces of the right filter piece 91 and the left filter piece 92. To do.

  The filter 13 assembled in such a procedure is shown in FIG. The filter 13 shown in FIG. 5 (·) shows a state in which the right filter piece 91 and the left filter piece 92 are spread on both sides, and the nose fitter 93 is linearly deformed. 107 rises three-dimensionally by the curves of the nose lines 96 and 97, and changes to a shape that can cover the nose and mouth of the human body. When the right filter piece 91 and the left filter piece 92 are folded, the nose fitter 93 is folded at the center thereof, and the inner surfaces of the right filter piece 91 and the left filter piece 92 can be deformed so as to be in close contact with each other. .

  The right filter piece 91 and the left filter piece 92 are made of a material having air permeability and a function of collecting viruses, pollen, bacteria, dust and the like. Even a single non-woven fabric conventionally used for masks can fulfill a temporary function, but in order to obtain a good effect, a material in which a plurality of non-woven fabrics having different functions are stacked is preferable. It is. For example, two sheets of anti-viral processed full-tect (registered trademark of Shikibo Co., Ltd., a material mixed with half of rayon and polypropylene) and non-woven fabric with high functionality for bacterial collection, The four layers of polypropylene non-woven fabrics are layered on the front and back of the two materials, and using a four-layered non-woven fabric that integrates them, the virus infectivity is reduced, and high-performance non-woven fabrics are used for pollen, bacteria, Bacteria and dust can be collected efficiently. In addition, since the nonwoven fabric is not made into a single layer but is made into four layers and thickened, the moisture retention is improved, and the softness is improved because it becomes softer. In addition, even if it is not a nonwoven fabric like this illustration, the other material which can perform an antiviral and a pollen allergy effectively as a filter by superimposing in multiple layers is also considered.

  FIG. 6 shows the external appearance of the valve mechanism 14 and the cap 16 shown in FIG. 2, and a pair of the valve mechanism 14 and the cap 16 are combined to attach them to the mask cover 12 and the filter 13. The filter 13 can be attached to the mask cover 12. The valve mechanism 14 has the same structure as the valve mechanism 15, and the cap 16 has the same structure as the cap 17. For this reason, description of the structure of another set of valve mechanisms 15 and caps 17 is omitted.

  FIG. 7 shows a state in which the valve mechanism 14 is opened, and the inside of the valve mechanism 14 is illustrated. The valve mechanism 14 includes a main body 111, a lid portion 112, and a hinge 113, and these three parts are integrally formed by injection molding or the like. Since the thickness of the hinge 113 is thin, the lid 112 can be rotated at an angle of 180 degrees with the hinge 113 as the center of rotation with respect to the main body 111, and can be opened and closed. Can do. The main body 111 that forms the backbone of the valve mechanism 14 has a horseshoe shape as a whole when viewed from the front, and a base 115 is the base that supports the whole. The base 115 has a flat shape, and a cylindrical engagement cylinder 138 is connected to the center of the base 115 downward in FIG. 7, and a vent hole 119 opened in the vertical direction is opened by the engagement cylinder 138. That's right. In the inner space of the engagement cylinder 138, a support column 120 that also serves as a reinforcement is bridged in a direction perpendicular to the axis thereof, and the valve pin 121 is directed toward the front side in FIG. Is protruding. In addition, a pair of screws 125 and 126 are formed on the inner peripheral surface of the engagement cylinder 138, and the screws 125 and 126 are processed into a screw shape so as to be positioned obliquely on the inner peripheral surface of the engagement cylinder 138. is there.

  Peripheral walls 116 and 117 are formed around the base 115 so as to stand up from the surface of the flat base 115, and a frame like a band is formed around the base 115 by the peripheral walls 116 and 117. 116 and 117 form a space in the main body 111. A V-shaped protrusion 124 having an acute angle toward the center is formed at the center of the inner periphery of the base 115 which has an arc shape, and pin holes 122 and 123 are opened near the ends of the peripheral walls 116 and 117, respectively. It is. Further, a linear engagement surface 118 is formed at the end of the base 115 (a position corresponding to a horseshoe-shaped opening).

  Next, the entire lid portion 112 has a shape like a ginkgo leaf (a shape like a bee of a shamisen) with a circular arc at the top and gentle left and right sides. The hinge 113 is connected to the center of the position corresponding to the circular portion. The lid portion 112 can be opened and closed by a hinge 113 and can cover the surface of the main body 111 when folded toward the main body 111. In the center of the lid cover 127 near the hinge 113, a valve pin hole 129 to be fitted to the valve pin 121 is formed. 130 and 131 are projected. The lid cover 127 has a curve that narrows its left and right width from the upper part (right side in FIG. 7) to the lower part (left side in FIG. 7), and the lower end of the lid cover 127 (in FIG. 7). At the left end), a hook 128 is formed in a key shape. When the lid cover 127 is bent about the hinge 113 to approach the main body 111, the valve pin 121 enters the valve pin hole 129, the pin 130 enters the pin hole 122, the pin 131 enters the pin hole 123, and the hook 128. Meshes with the lower surface of the engagement surface 118.

  In addition, a valve membrane 134 is accommodated inside the valve mechanism 14, and the valve membrane 134 is formed of a flexible thin film membrane, and an engagement hole 135 is opened in a part of the valve membrane 134. In the vicinity of 135, a notch 136 is cut in a V shape. In the valve membrane 134, the valve pin 121 is inserted into the engagement hole 135 and the notch 136 is fitted with the V protrusion 124, whereby the entire valve membrane 134 can be held in the internal space of the base 115.

  The cap 16 is integrally formed by injection molding or the like, and there is an engaging cylinder 141 that is greatly opened in the front and rear at the center, and the inside of the engaging cylinder 141 is reinforced so as to be perpendicular to the axis thereof. No. 144 is spanned. A pair of claws 142 and 143 project from the outer periphery of the engagement cylinder 141, and a flat flange 145 extending outward is formed at the opening of one end (the lower surface side in FIG. 7) of the engagement cylinder 141. . The engagement cylinder 141 can be inserted into the engagement cylinder 138 of the valve mechanism 14, and the pair of claws 142 and 143 can be engaged with the screws 125 and 126, respectively.

  Next, a procedure for combining the valve mechanism 14 and the cap 16 with the mask cover 12 and the filter 13 will be described with reference to FIGS. 2 shows a state before the mask 11 is assembled, FIG. 1 shows a state after the mask 11 is assembled, and FIGS. 1 and 2 are also referred to. And easy to understand.

  First, in the assembly of the valve mechanism 14, the engagement hole 135 of the valve membrane 134 is inserted into the valve pin 121, the notch 136 is aligned with the V projection 124, and the valve membrane 134 is held in the internal space of the base 115. After that, the lid cover 127 is bent around the hinge 113, the valve pin hole 129 is fitted into the valve pin 121, the pin 130 is fitted into the pin hole 122, and the pin 131 is fitted into the pin hole 123.

Then, the lid cover 127 is integrated with the main body 111, and the valve membrane 134 in the base 115 is held inside, and this state is shown in FIG. 6, and its cross section is shown in FIG.

  Next, from the state where the mask cover 12 and the filter 13 are separated as shown in FIG. 2, the filter 13 is brought into close contact with the back surface of the mask cover 12, and the positions of the vent hole 21 and the vent hole 29 are aligned (not shown). However, the vent hole 22 and the vent hole 30 are also aligned). FIG. 8 shows a state where the mask cover 12 and the filter 13 are in close contact. In this state, the engagement cylinder 138 of the valve mechanism 14 is inserted into the vent holes 21 and 29 from the left side to the right side in FIG. 111 is brought into close contact with the surface of the mask cover 12. Then, the engagement cylinder 141 of the cap 16 is inserted from the right side to the left side in FIG. 8 into the engagement cylinder 138 while being inserted into the vent holes 21 and 29. Further, when the entire cap 16 is rotated and the claws 142 and 143 are brought into contact with the inclined surfaces of the screws 125 and 126 and screwed as shown in FIG. 9, the engagement cylinder 141 moves to the back of the engagement cylinder 138, and the flange 145 The side faces of the filter 13 come into close contact with the back surface of the filter 13.

  When the cap 16 is screwed into the valve mechanism 14 in this manner, as shown in FIG. 10, the mask cover 12 and the filter 13 are sandwiched between the inner surface of the base 115 of the valve mechanism 14 and the inner surface of the flange 145 of the cap 16 from the left and right. As a result, the mask cover 12, the filter 13, the valve mechanism 14, and the cap 16 are integrated, and the mask 11 is assembled. Although not shown, the valve mechanism 15 and the cap 17 similarly sandwich the mask cover 12 and the filter 13 from both sides.

  The operation of the assembled mask 11 will be described.

  To use the mask 11 assembled from the components shown in FIG. 2, the back side (right side in FIG. 2) of the filter 13 is applied to the nose and mouth, the ear strap 23 is hooked to the ear D, and the ear strap 24 is opposite. Hang on the side ear. The adjusters 25 and 26 are moved back and forth in a provisional state where the ear straps 23 and 24 are hung on the ear D, and adjustment is performed so that the ear straps 23 and 24 are perfectly held by the ear D. Then, the nose fitter 93 is deformed by pushing the center upper part from the surface of the mask cover 12 with a finger and adjusted so as to coincide with the curved surface of the nose C. Since the nose fitter 93 is formed of a soft and deformable metal or the like, the nose fitter 93 is deformed so that the upper part of the filter 13 is in close contact with the curved surface of the nose C, and can maintain its shape. In this way, the state in which the mask 11 is worn on the face of the head A is shown in FIG. 1, and the nose C and mouth are hidden by the mask 11 so that most of the cheek B is covered.

  If the mask 11 is thus worn, the human body inhales the outside air through the mask 11 and exhales from the human body, and the human body is kept in an environment where viruses and bacteria are floating such as crowds and hospitals. Can be protected. When the human body inhales, the right filter 13 side in FIG. 10 becomes negative pressure, the valve membrane 134 closes in close contact with the surface of the base 115, the outside air cannot pass through the engagement cylinders 138 and 141, and the intake air is not masked. It passes through the cover 12 and the filter 13. When the outside air passes through the filter 13, viruses, pollen, fungi, dust, etc. floating in the outside air are collected by the filter 13 to prevent entry into the human lungs. The filter 13 is composed of, for example, a non-woven fabric having antiviral properties and a non-woven fabric having a bacteria collecting function in a four-layer structure, so that the virus infectivity is reduced and bacteria, pollen, fungi, dust, etc. are efficiently removed. Can be collected to prevent adverse effects on the human body. Moreover, since the filter 13 has laminated the nonwoven fabric thickly on four layers, it has high moisture retention and soft contact with the skin, thereby reducing discomfort.

  Further, when exhaling from the human body, the right side of the filter 13 becomes positive pressure as shown in FIG. 11, so that the valve membrane 134 is bent to the left side in FIG. The ventilation hole 119 of 138 is opened. The exhalation from the human body flows as shown by the arrow in FIG. 11 and is exhaled smoothly without passing through the mask cover 12 and the filter 13.

  12 and 13 show a second embodiment of the present invention.

  FIG. 12 is an exploded view of the parts of the mask 11 and corresponds to FIG. 2 described above. The difference from FIG. 2 is a method of attaching the ends of the ear straps 23 and 24 to the mask cover 12. Is different. The method of attaching the ear straps 23 and 24 is described in detail with reference to FIG.

  In FIG. 13, one end of the ear strap 23 is inserted into the eyelet 71, and its end is bent outward to form a bent portion 161, and the other end of the ear strap 23 is inserted into the eyelet 72. The bent portion 162 is bent outward. The ends of the bent portions 161 and 162 are arranged close to the positions of the ear lines 43 and 59. Similarly, one end of the ear strap 24 is inserted into the eyelet 73, and its end is bent outward to form a bent portion 163, and the other end of the ear strap 24 is inserted into the eyelet 74, and its end is outside. The bent portion 164 is bent. The ends of the bent portions 163 and 164 are arranged close to the positions of the ear lines 44 and 60.

  When sewing the right front cloth 35, left front cloth 36, right mesh cloth 37, left mesh cloth 38, upper edge cloth 81, right edge cloth 82, left edge cloth 83, and lower edge cloth 84, The right edge cloth 82 is put on the sides of the lines 43 and 59 so as to have a V shape, and the ends of the bent portions 161 and 162 are inserted into the right edge cloth 82 at the same time. Thereafter, the front and back surfaces of the right front cloth 35 and the right mesh cloth 37 are sewn together with the right edge cloth 82 by the sewing machine, and at the same time, the ends of the bent portions 161 and 162 are sewn inside the right edge cloth 82. Similarly, the left edge cloth 83 is placed on the sides of the ear lines 44 and 60 so as to be V-shaped, and the ends of the bent portions 163 and 164 are inserted into the left edge cloth 83 at the same time. Thereafter, the front and back surfaces of the right front cloth 36 and the right mesh cloth 38 are sewn together with the left edge cloth 83 by the sewing machine, and at the same time, the ends of the bent portions 163 and 164 are sewn into the left edge cloth 83.

  By sewing in this way, as shown in the enlarged view in the upper right of FIG. 13, the bent portion 163 is sewn and positioned inside the left edge cloth 83, and the end of the ear strap 24 may fall off from the eyelet 73. Disappear. The other bent portions 161, 162, and 164 are sewn in the same manner.

  As described in the above embodiment, in this embodiment, the surface of the mask is a flat fabric, so it is possible to use various patterns and dyed or printed fabrics, not single color or white. You can express your favorite designs and colors. A conventional mask that displays the nonwoven fabric as it is is a single color and may not match the color of the clothing, but the design of the clothing can be selected freely. It is possible to use a mask that matches the color and design.

  With the mask, the mask cover and filter can be disassembled, the filter can be removed depending on the frequency of use, and a new filter can be replaced, so that it can always be used in a sanitary manner and has the ability to collect viruses and pollen. It can be used in good condition.

  Since the valve mechanism is attached to the mask, the valve is closed during inhalation and the valve is opened during exhalation. For this reason, when inhaling, outside air passes through the filter and is filtered, and viruses and pollen are collected. At the time of exhalation, since the breath passes through the valve mechanism and is discharged to the outside, the burden on the human body is reduced.

  In order to attach the valve mechanism to the mask, the valve mechanism can be assembled by simply inserting the valve mechanism into the opening of the mask and screwing the cap from the rear side.
