Description

  The present invention relates to a sanitary mask that is excellent in antiviral properties and fit properties by applying an antiviral agent to a fabric and utilizing a knitted fabric.

  In order to cope with the damage caused by viruses and other diseases, anti-virus processed fibers have been developed for clothing and bedding for textile products, and sanitary masks have some anti-viral activity. A mask is disclosed (Patent Document 1).

  On the other hand, in this sanitary mask, a gauze mask and a non-woven fabric mask are generally used. The gauze mask is rough and the non-woven mask is fine. If the anti-virus processing is applied to this non-woven mask, it is better. Although it is expected that a virus infection prevention effect is obtained, a sanitary mask having a sufficient infection prevention effect has not yet been obtained.

  Therefore, when the present inventor has closely observed the manner in which a human hygiene mask is used, in the above mask, there is a relatively large gap between the nose part and the auricle part that form the peripheral part of the mask. It is observed that it tends to occur, and even if anti-virus processing is applied to the non-woven fabric mask, the conclusion is that the virus will enter from this gap and the anti-viral effect of the mask will be halved. It came to.

  Therefore, as a result of further research, the present inventor has focused on the function of a knit fabric rich in stretchability as a sanitary mask fabric, and solves the problem of gaps and the like by utilizing the stretchability of this knit fabric. It has been successful.

  Thus, the present invention is intended to satisfy the infection prevention function of the sanitary mask by the antiviral agent, and at the same time, to solve various problems in use as a mask generated from the knit fabric. .

  In addition, although the technique which has the layer which consists of the knitted fabric which knit the multilayer structure yarn with respect to the sanitary mask is disclosed (patent document 2), this is what expects hygroscopicity to the cotton fiber used for a sheath part simply. Therefore, the stretchability of the knitted fabric is not used for the mask fabric.

  The sanitary mask disclosed in Patent Document 1 is a combination of an antiviral agent and an activated carbon sheet, and is different from the antiviral sanitary mask with excellent fit of the present invention. is there.

The antiviral mask of the present application is composed of two or more layers of a knitted fabric with an antiviral agent and a knitted fabric without an antiviral agent, and covers the nose, lower jaw, and left and right auricles. Then, the mask body is formed by overlapping the knitted fabric with the antiviral agent on the front side and the knitted fabric without the antiviral agent on the inner side in contact with the nose portion and the lower jaw portion, , Hanaitadaki part, outside of the left auricle portion, the lower jaw, along the periphery connecting the outer right ear portion to form a frame body forming a border of constant thickness knit fabric, a central portion, of the nose portion A non-stretchable joint that forms a space covering the bottom of the nose and the lips is formed.

According to a second aspect of the present invention, the knit fabric is made of polyester fiber, and an acrylic resin having paste properties is attached as a bonding agent.

According to a third aspect of the present invention, the frame body forming the edging is characterized in that a knitted fabric of a band body has a binder finish.

According to claim 4, in the mask body, to form the frame body inside of both auricles of the left and right, it characterized the kite.

According to claim 5 , the joint portion is made of two knitted fabrics cut into a fan-shaped outer bulge, the joint portion is sewn, and the ends opened to the left and right are stitched and stitched as two split stitches. It is characterized by being sutured.

  When the mask body of the present invention is attached to the face, the frame is slightly stretched and hooked on the nose, lower jaw, and both left and right auricles, and the force in the shrinking direction (inward direction) is applied as a reaction force of the knit fabric against the extension. This produces an effect of bringing the frame into close contact with the face, and it is possible to prevent the invasion of viruses as much as possible.

  Even if there is a possibility that a gap is generated between the inside of the auricle portion serving as the end portion and the mask main body, a frame body with a constant thickness border is formed with a knit fabric over the inside of both auricles. Therefore, virus invasion can be prevented by the adhesion due to the contraction force.

  At the same time, when the close contact with the face by the frame is promoted, the stretchable knitted fabric itself is in close contact with the cheek and chin, and in addition to the virus intrusion prevention effect by the frame, The invasion prevention effect in the meaning of heavy is promoted.

  In the present invention, the antiviral agent applied to the mask fabric acts on the virus when the frame of the knit fabric and the fabric ground prevent the entry of the virus resulting from the gap as much as possible. The effect of ions, copper ions, etc. produces an effect of greatly reducing the number of ions. According to the drug used in the present invention, if the virus activity value is 3.0 or more, an effect of reducing it to 1 / 1,000 or less can be expected.

  On the other hand, when the mask body is a knitted fabric, the adhesiveness is too short due to its stretchability, and there is a risk of restraining breathing and movement of the mouth. A non-stretchable joint that covers the space is formed, so even if you move your lips during conversation or breathing, there will be no change such as expansion or contraction due to the knit fabric. This can be done.

  At this time, since the antiviral agent is not applied to the inner body, the conversation, breathing, and the like can be made smoother.

In the invention according to claim 2, even if there is a possibility that a gap is generated between the protruding nasal apex and the mask main body, an inner curved curved portion is formed on the left and right at the central apex at the nasal apex of the mask main body. Therefore, the curved inner concave portion is fitted to the bulge of the nose, and both are brought into close contact with each other, thereby enhancing the effect of preventing virus entry.

In the invention according to claim 3, when an acrylic resin having paste properties is attached to the knit fabric as a bonding agent, the acrylic resin having paste properties follows even if the knit fabric is pulled and the stitches are enlarged. The gap formed in the stitches can be narrowed, and the gap ensures air permeability necessary for breathing.

In the invention of claim 4, wherein the frame body forming the border, when the knitted fabric of the strip and the binder finish, some stretch leave but stretchable body knitted fabric becomes what was suppressed to some extent .

In the invention according to claim 5 , in the mask body, the frame is also formed on the left auricle part and the right auricle part formed along the outer periphery extending outside the left and right auricle parts, the frame body by forming the bulge outside ring can enhance the adhesion further.

In the invention described in claim 6 , the joint portion is made by combining two knit fabrics cut into a fan-shaped outer bulge, the stitched portion is sewn, and the ends opened to the left and right are stitched and stitched as two split stitches. When stitched non-stretching, non-stretching of the joint is ensured, and breathing, conversation, etc. can be performed stably.

  EMBODIMENT OF THE INVENTION Hereinafter, the form for implementing the antiviral sanitary mask which concerns on this invention is demonstrated based on drawing.

  The antiviral agent is used for the purpose of reducing viruses adhering to the knit fabric, which will be described later, and for example, an amino group having silver ions, copper ions, zinc ions or the like added thereto can be used. Specifically, C125 Co., Ltd. K125 can be mentioned, and according to the product, antiviral test certification stipulated in 2014 ISO 18184 can be obtained. When the anti-virus activity value is 3.0 or more in the ISO18184, the number of viruses can be reduced to 1 / 1,000 or less.

  In the present invention, in view of the stretchability of the knitted fabric, it is desirable to apply a bonding agent between the antiviral agent and the fabric.

  This bonding agent refers to a material having a function of improving the function of an antiviral agent on a fabric.

  For example, when the knit fabric is made of polyester resin, an acrylic resin having paste properties can be used as a bonding agent. A mixture of acrylic resin and distilled water is prepared as the antiviral agent, and the knit fabric is added to the mixture. After being dipped, it can be pulled up and dried for a predetermined time.

  When the knitted fabric is stretched, the adhesive agent having adhesiveness extends following the knitted fabric, and it is possible to narrow the gap between the knitted fabrics.

  Between fabrics, the performance which contradicts the air permeability accompanying breathing and the shielding property which prevents invasion of a virus is requested | required, but both adjustment is achieved by the said structure.

  Also, it can withstand washing due to the bonding between the bonding agent and the fiber.

Next, a knit fabric rich in stretchability is used for the mask fabric used in the present invention (see FIGS. 1 and 2).

  Here, the knit fabric refers to a fabric that is stretched and contracted (stretchable) by knitting.

  For example, circularly knitted 75th yarn of polyester fiber can be used.

  Polyester is excellent in adhesion to an antiviral drug described later, and a thread of about No. 75 is suitable for knitting the mask and ensuring air permeability.

  In the present invention, it consists of two or more layers of a knitted fabric with an antiviral agent and a knitted fabric without an antiviral agent. A knitted fabric is used, and the mask body 10 is formed by overlapping the knitted fabric not applied with the antiviral agent on the inner body 12 in contact with the nose and the like.

  On the front side in contact with outside air, an antiviral agent that protects against invading viruses is applied, but on the inner side in contact with lips, nose, cheeks, etc., this is not applied for the purpose of avoiding damage from the drug .

  In addition, it is possible to provide two or more layers by providing an intermediate layer or the like as necessary.

  The form of the mask body 10 is a length from the nasal apex portion 21 (part of the raised nose) to the lower jaw portion 22 (portion entering the throat direction of the lower jaw) in the vertical direction, and one right side in the left-right direction. Alternatively, the length starts from the back side of the left pinna and reaches the back side of the other left or right pinna (see FIGS. 1 to 4 and 8).

  As a whole, the entire nose, left and right auricles, and lower jaw are covered.

  With such a configuration, the face can be covered widely, and an adhesion effect of the peripheral frame 20 described later is derived.

Next, a frame body 20 is formed along the outer periphery of the mask body 10 to form a border having a certain thickness with a knitted fabric (see FIGS. 1 and 2).

  Here, as the frame body 20, a long knitted fabric having a constant width (band shape) is prepared, and this can be obtained by binding the belt body along the outer edge of the two knitted fabrics. . For example, two knitted fabrics are overlapped with borders equivalent to two strips, so that a total thickness of four sheets is formed, and a frame having a thickness twice that of the main body knitted fabric is formed ( (See FIG. 3).

  The frame body 20 is knit fabric and has elasticity, but its elasticity is suppressed by the stitching of the binder finish, and generally the elasticity of the main body knit fabric is suppressed to some extent although some elasticity remains. .

  In the form of the mask main body 10, the nasal apex portion 21 is formed with an inner curved left curved portion 21 a and a right curved portion 21 b at a location located at the apex of the nose portion with the apex at the upper center of the mask as a boundary. (See FIG. 5).

  Since the human nose is raised and has a slightly outward bulging shape, when the opposite curved concave portion is formed from the apex of the nose according to the bulging, both are fitted together, and the frame 20 is the nose. Adhesiveness that does not cause a gap as much as possible between the parts can be maintained (see FIG. 8).

  Moreover, you may attach the nose stopper made from a polyester resin as needed.

  The lower jaw portion 22 of the mask main body 10 is hung on the bottom portion of the lower jaw and covers the portion of the lower jaw that enters the throat.

  This is for enhancing the adhesion effect of the frame body by covering the nose part, the left and right auricle parts, and the lower jaw part as a whole.

On the other hand, in the left-right direction, in addition to forming the left auricle portion 23a and the right auricle portion 23b along the outer periphery extending to the outside of both auricles, the inner left auricle is trimmed with a constant thickness with a knitted fabric inside the auricle. A medial part 24a and a right inner auricular part 24b are formed (see FIGS. 1 and 6).

  The left auricular portion 23a and the right auricular portion 23b along the outer circumference extending to the outside of the left and right auricles exert an adhesive force from the nasal apex portion 21 toward the auricular outer side. A gap is easily generated between the two.

  Therefore, the left inner pinna portion 24a and the right inner pinna portion 24b are also formed on the inner side of the pinna to prevent the gap between both pinna and the cheek from being generated.

  At this time, it is desirable to form the left auricle portion 23a and the right auricle portion 23b along the outer periphery in a ring shape so as to bulge out with respect to the left inner auricle portion 24a and the right inner auricle portion 24b on the inner periphery (see FIG. 6). ).

  As shown in FIG. 7, the end of the knitted fabric piece is elongated along the frame 20, and the end is shifted from the other end to make it long (FIG. 7A). Can be rounded into a ring shape and the end can be fixed to one end (FIG. 7B), and the periphery can be sewn with a band (FIG. 7C).

  In the central part, a non-stretchable joint 13 is formed which covers the lower nose and the lip and forms a space S (see FIG. 9).

Specifically, the central portion of the mask main body 10 is separated into left and right, and is cut into a fan shape having an external bulge that maintains a constant space between the nose and the lips, and the front main body 11 is cut to the left of the front main body. A piece 11a, a front-side main body right piece 11b, an inner main body 12 as an inner main body left piece 12a, an inner main body right piece 12b, and the front-side main body left piece 11a, front-side main body right piece 11b, and inner main body left piece 12a, inner side The main body right pieces 12b are stitched together so as to be non-stretchable with no stretchability as much as possible. The joined portion 13 is formed with the front side as the front side joined portion 13a and the inside as the inside joined portion 13b (see FIGS. 1 and 2).

  This stitching is possible by, for example, stitching both fabrics with the remainder left outside, then opening the remainder, stitching the edges, stitching into two stitches, and double stitching. Non-stretchability can be obtained.

  That is, if the knit stretch is applied as it is, it reaches the bottom of the nose and the surface of the lips.

  Therefore, when the lips are shaped so as to maintain a sufficient space S and are joined by double stitching, even if lip movements occur due to nasal breathing and conversation, the knit stretchability is It will be suppressed and this will not be disturbed.

  A filter layer can be interposed between the front side main body 11 and the inner side main body 12 with a nonwoven fabric or the like.

  Below, the effect of this invention is demonstrated.

  In the mask of the present invention, a mask main body 10 is formed so as to cover a nose part, a lower jaw part, and both left and right auricle parts, and a frame body 20 that forms a border of a constant thickness with a knitted fabric along the outer periphery of the mask main body 10. Formed (see FIGS. 1 to 3).

  The frame body 20 is made of knit fabric and has elasticity, but its elasticity is suppressed by stitching, and some elasticity remains, but the elasticity of the main body knit fabric is suppressed to some extent.

  Therefore, when the mask body 10 is attached to the face in use, the frame 20 is slightly stretched and applied to the nose, the lower jaw, and the left and right auricles. A force acts in (inward direction) (see FIG. 8).

  When a knit fabric rich in stretchability is stretched by a tensile force, a reaction force is generated there, and the reaction force pulls the frame 20 inward.

  As a result, the frame body 20 hung on the nose part, the lower jaw part, and the left and right auricle parts slightly contracts inward, and this produces the effect of closely attaching the frame body 20 to the face.

  That is, in the conventional mask, a gap is likely to be generated in the peripheral portion of the mask, and this is a factor that allows the virus to enter the nose and mouth. The frame body 20 formed so as to cover the left and right auricle parts is in close contact with the face, and it is possible to prevent the virus from entering as much as possible.

At this time, there is a tendency that a gap is likely to be generated between the protruding nasal apex 21 and the mask main body 10 due to the unevenness, but the nose apex 21 of the mask main body 10 of the present application is inward to the left and right with the central vertex as a boundary. Since the curved left curved portion 21a and the right curved portion 21b are formed, the inner curved curved concave portion is fitted to the bulge of the nose portion, and both are brought into close contact (see FIGS. 5 and 8). ).

  As a result, the effect of preventing the entry of the virus is further enhanced.

  At the same time, as described above, there is a tendency that a gap is easily generated between the inside of the auricle portion serving as the end portion and the mask body 10.

Therefore, as described above, in addition to forming the left auricle portion 23a and the right auricle portion 23b along the outer periphery extending to the outside of both auricles, the left inner auricle is trimmed with a certain thickness on the inner side of the auricle with a knitted fabric. A portion 24a and a right inner pinna portion 24b are formed (see FIGS. 3 and 6).

  Then, the frame body 20 is formed over the outer side and the inner side of the auricle part, and virus invasion can be prevented by the adhesiveness accompanying the contraction force.

  At this time, when the left auricle portion 23a and the right auricle portion 23b along the outer periphery are formed in an outer bulge in a ring shape with respect to the left inner auricle portion 24a and the right inner auricle portion 24b on the inner periphery, a swelled annular frame body 20 becomes a form along an auricle part, and contact | adhesion power can be strengthened further (refer FIG. 7).

  As shown in FIG. 7, the end of the knitted fabric piece is elongated along the frame 20, and the end is shifted from the other end to make it long (FIG. 7A). The ring 20 is rounded and the end is fixed to one end (FIG. 7B), and the periphery thereof is sewed with a binder (FIG. 7C), so that the formation of the frame body 20 becomes more complete.

  In addition to the virus invasion preventing effect by the frame body 20, a close effect of the face and the knitted fabric on both cheek surfaces, the upper jaw and the lower jaw by the knit fabric can be expected.

  That is, when the close contact action with the face by the frame body 20 is promoted, for example, the stretchable knitted fabric itself is in close contact with the portion of the cheek that is slightly swollen and the protruding upper and lower jaws. (See FIG. 8).

  As a result, in addition to the virus intrusion prevention effect by the frame 20, the virus intrusion effect due to adhesion can be expected also at this part, and the effect in a double sense is promoted.

  Now, when the frame 20 and the fabric itself prevent the invasion of viruses from the gap as much as possible, in the present invention, the antiviral agent applied to the fabric itself acts on the virus, Produces the effect of reducing the number.

  That is, the antiviral agent used in the present invention is effective for, for example, silver ions, copper ions, zinc ions, etc. added to amino groups acting on viruses entering from the stitches of the knit fabric with respiration. Work to reduce to.

  As a result, according to the drug used in the present invention, it was confirmed that the virus activity value was 3.4, so that the effect of reducing it to 1 / 1,000 or less can be expected.

  According to this value, due to human immunity, the effect is sufficiently exerted on the invading virus, and it can be expected to prevent many diseases caused by the virus.

  At this time, the knit fabric has a tendency to expand the fabric stitch when it is pulled because of its elasticity.

  Therefore, an acrylic resin having paste properties can be attached as a bonding agent.

  As a result, even when the knitted fabric is stretched, the acrylic resin having paste properties can follow and extend, and the voids generated by the stitches can be narrowed, and the voids ensure the breathability necessary for breathing. .

  Further, in the application of this antiviral agent, it is necessary to protect against the invading virus on the front side in contact with the outside air, but there is a concern about the harm of the drug in the inner main body 12 in contact with the lips and the like.

  Therefore, an antiviral agent is applied to the front side main body 11, but an antiviral agent is not applied to the inner side main body 12 so that there is no contradiction.

  By the way, when the mask body 10 is a knitted fabric, because of its stretchability, if it covers the lower nose, lips, etc. in the form as it is, the adhesiveness will pass, suppressing breathing and movement of the mouth, May cause difficulty in breathing and conversation.

  Therefore, a non-stretchable joint 13 that forms the space S covering the nose and lips is formed in the center, for example, the center of the mask body 10 is separated into left and right, and the nose and lips 9 is cut into a fan shape with an outward bulge so as to maintain a constant space between the left and right parts, and the left and right pieces are sewn together so as to be non-stretchable with no stretchability as much as possible (FIG. 9). reference).

  As a result, a space S covering the lower nose and the lips is formed, and the space S is non-stretchable, so even if the lips are moved in conversation or the like, This can be performed stably without causing a change such as enlargement or reduction due to the knit fabric.

  At this time, two knit fabrics cut into a fan-shaped bulge at the center are joined together, the stitches are sewn together, and the ends opened to the left and right are stitched and stitched as two split stitches. When sutured, the non-stretchability of the joint is ensured, and breathing, conversation, etc. can be performed stably.

  Further, the aspect in which the antiviral agent is not applied to the inner main body 12 can make the conversation, breathing, and the like smoother.

  Next, other embodiment which implements the antiviral hygiene mask which concerns on this invention is described based on drawing using FIGS. In the description of the present embodiment, the description of FIGS. 1 to 9 described above is referred to as appropriate, and the repeated description is omitted as much as possible. Therefore, regarding the constituent members of the antiviral sanitary mask M of the present embodiment, the same reference numerals are used for the same constituent members as the above-described antiviral sanitary mask.

  FIG. 10A is a perspective view for explaining the appearance of the antiviral sanitary mask M of this embodiment viewed from the front side. FIG. 10B is a perspective view for explaining the external appearance of the antiviral sanitary mask M of this embodiment viewed from the inside. FIG. 10C is a plan view for explaining the replaceable fabric 106 of the antiviral sanitary mask M of the present embodiment.

  As shown in FIG. 10A, the mask main body 100 of the antiviral sanitary mask M is mainly attached to the front side main body 101, the inner main body 102, the left auricle portion 103, and the right auricle portion 104. Sections 105 and 108 and replaceable fabric 106 are included. The different structures of the mask main body 10 described above and the mask main body 100 of the present embodiment are mainly formed on the materials used for the front side main body 101 and the inner main body 102 and their knitting structures, and on the front side main body 101 and the inner main body 102. The shape of the nasal apex 107, the material used for the left auricle 103 and the right auricle 104, and the structure thereof, the engaging portion 105 newly provided in the inner body 102, the replaceable fabric 106 and the replaceable fabric There is an engaging portion 108 provided in 106.

  In the following description, the difference will be mainly described. The mask body 100 is also provided with a frame body 20 in the same manner as the mask body 10. In addition to the effect of preventing the virus from entering the frame body 20, the mask body 100 covers both cheek surfaces, upper jaws and lower jaws of the cotton fabric of this embodiment. It is the same that the adhesion effect between the face and cotton fabric can be expected.

  The front-side main body 101 has a front-side main body left piece 101a and a front-side main body right piece 101b. The front-side main body left piece 101a and the front-side main body right piece 101b are sewn together in the central region of the front-side main body 101, and the joint portion 13 Is formed. The sewing structure of the joint portion 13 is as described above, and a structure that obtains as much non-stretchability as possible by double stitching is realized, and the above-described space S is provided.

  The front-side main body left piece 101a and the front-side main body right piece 101b are formed of, for example, a fabric knitted by a warp knitting machine using cotton yarn. Warp knitting expands and contracts in one direction depending on the knitting method, and expansion and contraction in a direction orthogonal to the one direction is suppressed. And the front side main body left piece 101a and the front side main body right piece 101b are expanded and contracted with respect to the left and right direction, and expansion and contraction in the vertical direction is suppressed. Similar to the mask main body 10 described above, the mask main body 100 also mainly contracts in the left-right direction due to a structure that expands in the left-right direction. The main body 100 and the user's face can be easily adhered.

  The antiviral agent mentioned above is given to the front side main body 101. At this time, it is desirable that a bonding material be applied between the antiviral agent and the cotton fabric, similarly to the mask body 10 described above. Specifically, after preparing the liquid mixture which prepared the mixture of an acrylic resin and distilled water in the said antiviral agent, the front side main body 101 which is the cloth of cotton material was immersed in this liquid mixture, By pulling up and drying for a predetermined time, a bonding material is applied between the antiviral agent and the cotton fabric. In the front-side main body 101 as well, as in the mask main body 10 described above, there is a structure in which the fabric can be adjusted for the contradictory performance between breathability associated with breathing and shielding properties that prevent the invasion of viruses. Realized.

  As shown in FIG. 10B, the inner main body 102 has an inner main body left piece 102a and an inner main body right piece 102b, and the inner main body left piece 102a and the inner main body right piece 102b are the center of the inner main body 102. The joint 13 is formed by stitching in the region. The sewing structure of the joint portion 13 is as described above, and a structure that obtains as much non-stretchability as possible by double stitching is realized, and the above-described space S is provided.

  The inner main body 102 is formed of, for example, a fabric knitted by a warp knitting machine using a yarn made of cotton material, like the front side main body 101 described above. The inner main body left piece 102a and the inner main body right piece 102b expand and contract in the left-right direction, and expansion and contraction in the vertical direction is suppressed, so that the inner main body 102 also expands and contracts in the same direction as the front side main body 101. In the present embodiment, the inner body 102 is applied with the above-described antiviral agent as well as the front side main body 101, and furthermore, a bonding material is applied between the antiviral agent and the cotton fabric. Has been.

  For example, six engaging portions 105 are provided along the periphery of the inner main body 102. Then, the replaceable fabric 106 is attached to the inner main body 102 via the engaging portions 105 and 108. As shown in FIG. 10C, for example, a non-woven fabric is used as the replaceable fabric 106, and the shape is slightly smaller than the inner main body 102. The replaceable fabric 106 is provided with, for example, six engaging portions 108 at locations corresponding to the engaging portions 105 of the inner main body 102.

  Here, for example, a hook-and-loop fastener is used as the engaging portions 105 and 108, and a loop is provided on one side and a hook is provided on the other side, so that the replaceable fabric 106 is attached to and detached from the inner body 102. Can be attached freely. The structure of the engaging portions 105 and 108 is not limited to a hook-and-loop fastener, but may be a button or a fastener.

  The mask main body 100 has a three-layer structure of a front side main body 101, an inner main body 102 and a replaceable fabric 106, and the replaceable fabric 106 plays a role as a filter layer of the mask main body 100. Even when a minute air pollutant such as PM2.5 or dust passes through the front main body 101 or the inner main body 102, the air pollutant can be obtained by the replaceable fabric 106 interposed in front of the user's mouth. Is greatly prevented from entering the human body.

  The front main body 101 and the inner main body 102 of the mask main body 100 can be repeatedly washed and used in the same manner as the mask main body 10 described above. On the other hand, since the replaceable fabric 106 abuts on the user's mouth and face, the user's saliva, sweat, and female cosmetics are likely to adhere. Therefore, it becomes possible for the user of the antiviral sanitary mask M to use the antiviral sanitary mask M in a sanitary manner by appropriately replacing and using the replaceable fabric 106 by the disposable method. .

  In addition, the front side main body 101 and the inner side main body 102 are being fixed by the frame 20 provided in the circumference | surroundings. The frame 20 is sewn so as to sandwich the front main body 101 and the inner main body 102. With this structure, the front main body 101 and the inner main body 102 are fixed in an annular shape around the periphery, but the inner side is not fixed. For example, a cut may be provided in the inner main body 102 along the engaging portion 105, and a dust filter or an aroma material may be inserted between the front main body 101 and the inner main body 102.

  FIG. 11 is a side view for explaining the appearance of the antiviral hygiene mask M of the present embodiment folded. In FIG. 11, the antiviral hygiene mask M is folded in half at the central joint 13 and viewed from the left side surface.

  As shown in FIG. 11, the nasal apex portion 107 of the mask main body 100 is formed at an acute angle with respect to the nasal apex portion 21 of the mask main body 10 described above. Specifically, the angle α of the nasal apex portion 107 is α <β with respect to the angle β (see FIG. 3) of the nasal apex portion 21, an acute angle, and the nasal apex portion 107 is longer in the upward direction than the nasal apex portion 21. Is formed. With this structure, the nasal apex portion 107 is mounted along the user's nose muscles so as to wrap up to the upper portion of the nose portion. As described above, the front main body 101 and the inner main body 102 expand and contract in the left-right direction of the mask main body 100 and are difficult to expand in the vertical direction due to the warp knitting shape. Attached in close contact along the concavo-convex shape. With this structure, the gap between the user's nose and the mask body 100 is further reduced, and the entry of viruses from the gap is prevented.

  The shape of the mask main body 100 is substantially the same as the shape of the mask main body 10 described above except for the shape of the nasal apex 107 described above. It has a shape that covers. Similarly to the mask main body 10, a frame body 20 made of the same fabric as the front main body 101 and the inner main body 102 is formed on the outer periphery of the front main body 101 and the inner main body 102. A silicon core material (not shown) that is deformed along the shape of the user's nose is disposed in the frame 20 of the nasal apex 107. After the user wears the antiviral sanitary mask M, the antiviral sanitary mask M is not easily displaced from the face by deforming the core material in accordance with the shape of his nose.

  FIGS. 12A and 12B are side views for explaining the structure and manufacturing method of the binaural parts 103 and 104 of the antiviral sanitary mask M of this embodiment. 12A and 12B show the antiviral sanitary mask M viewed from the front side and will be described with the left auricle portion 103, but the right auricle portion 104 has the same structure. And since it becomes a manufacturing method, the description is referred and abbreviate | omitted.

  As shown in FIG. 12A, the structure in which the left auricle portion 103 is different from the left auricle portion 23a described above is that a rubber-like portion 109 is disposed therein. One end of the rubber-like portion 109 is fixed to the upper end portions of the front side main body 101 and the inner main body 102 by stitching, for example. On the other hand, the other end of the rubber-like portion 109 is fixed to the lower end portions of the front-side main body 101 and the inner main body 102 by sewing, for example. The left and right end portions of the front side main body 101 and the inner side main body 102 are fixed by the cross frame 20b in the vertical direction as in the case of the frame 20.

  As shown in FIG. 12B, the frame body 20 extends from the periphery of the front side main body 101 and the inner side main body 102 and is sewn along the rubber-like portion 109, so that the left side along the outer side of the auricle is left. The auricle portion 103 is formed. That is, the frame 20 is formed in an annular shape from the periphery of the front main body 101 and the inner main body 102 to the left auricle portion 103 and the right auricle portion 104 (see FIG. 10A).

  In the mask main body 100, the left auricle portion 103 expands and contracts in accordance with the expansion and contraction of the rubber-like portion 109 according to the size and shape of the user's face, thereby improving the adhesion between the mask main body 100 and the user's face. Is done. Further, the left auricle portion 103 is repeatedly pulled by the user when worn, and is further repeatedly washed together with the mask body 100, but the rubber-like portion 109 is disposed inside, so that the rubber-like portion is arranged. The shape returns to match 109, and the left auricle 103 is prevented from extending completely. And even if it uses antiviral hygiene mask M repeatedly, the fall of the adhesiveness to a user's face is prevented significantly.

  FIG. 13 is a diagram for explaining the results of the antiviral test at the Japan Textile Products Quality Technology Center.

  In this test, the test method is ISO18184, which is an antiviral test method for textile products. The test outline is that the test virus is influenza A virus (H3N2), the host cell is MDCK cell (canine kidney-derived cell), the test sample is 0.4 g of fabric used for the mask body 100, and the washing solution Is SCDLP medium, the standing condition is 25 ° C. for 2 hours, and the infectivity titration method is a plaque measurement method. In addition, as a selection method, it is suspension hanging according to JIS L 0217 103, and a JAFET standard combination detergent is used.

Specifically, first, a host cell is infected with a virus, and after culturing, the cell residue is removed by centrifugation to obtain a virus suspension. Next, the virus suspension is diluted 10-fold with sterilized distilled water, and adjusted to 2 ± 1 × 10 ⁷ PFU / mL is used as a test virus suspension. Next, 0.2 mL of the test virus suspension is inoculated into each specimen. Next, after standing at 25 ° C. for 2 hours, 20 mL of the washing solution is added and stirred with a vortex mixer to wash out the virus from the specimen. Finally, the virus infectivity titer is measured by the plaque measurement method.

  As shown in the figure, the antiviral activity value is 4.0 or more in the fabric of the mask body 100 of the present embodiment, and the antiviral activity value is 4.0 or more in the fabric after three washings. Test results were obtained. And in this embodiment, the effect which reduces the effect | action of a virus to 1 / 10,000 or less is acquired because an antiviral activity value will be 4.0 or more.

  Also from the above test results, the antiviral sanitary mask M of this embodiment uses the fabric knitted with the cotton material, and the antiviral function is not easily lowered even after repeated washing. Was proved. As described above, the antiviral sanitary mask M has an antiviral property even when repeatedly washed and used due to the structure in which the antiviral agent is applied to the front main body 101 and the inner main body 102 of the mask main body 100. Function can be obtained for a long time. Note that there is no health problem even if the user's mouth is in direct contact with the fabric to which the antiviral agent is applied. However, in this embodiment, the user's mouth is resistant to the gap between the user's mouth and the inner body 102. By providing the replaceable fabric 106 that is not applied with a virus agent, consideration is given to the user who is concerned about the contact.

  In the present embodiment, the case has been described in which the replaceable fabric 106 is made of, for example, a non-woven fabric and the engaging portion 108 is provided on the surface thereof. However, the present invention is not limited to this case. For example, when the replaceable fabric 106 is directly locked to the engaging portion 105 of the inner main body 102, the replaceable fabric 106 may not be provided with the engaging portion 108. Various modifications can be made without departing from the scope of the present invention.
