Description

  The present invention relates to a mask that covers a part of the face and a method of manufacturing the mask.

  2. Description of the Related Art Conventionally, masks have been known that have improved sealing properties with the face and comfort of wearing. For example, the mask described in Patent Document 1 is a non-woven mask composed of a face covering part and an ear covering part, and the face covering part is made of a continuous integral non-woven cloth.

Unexamined-Japanese-Patent No. 2007-54381

  However, the conventional mask is made of only one type of material, which is a continuous integral nonwoven of the face covering portion. For this reason, the conventional mask has characteristics of only one type of material. In addition, conventional masks generally do not have two or more types of stretchable materials. Therefore, the mask of the related art can not have other functions in the mask having stretchability.

  An object of the present invention is to provide a mask and a mask manufacturing method having other functions in addition to stretchability.

  The mask according to the first aspect of the present invention includes a covering portion covering a part of the face including the mouth, and a direction connecting the ear hooks formed on both ends is a longitudinal direction, and a direction orthogonal to the longitudinal direction A mask main body formed by a bonding sheet, which is a sheet including the covering portion and the ear hooking portion, wherein the first layer, the second layer, and the third layer are joined. The first layer, the second layer, and the third layer are all made of a stretchable material, and the third layer is adjacent to the second layer and opposite to the first layer. It is characterized in that at least two layers of the first layer, the second layer, and the third layer which are joined are materials formed by different kinds of materials or manufacturing methods.

  In this case, the mask main body including the covering portion and the ear hooking portion is formed of a bonding sheet which is a sheet in which the first layer, the second layer, and the third layer are bonded. At least two layers of the first layer, the second layer, and the third layer are materials formed by different types of materials or manufacturing methods. Therefore, in addition to the elasticity, the mask body has another function, that is, a function according to the material of the first layer, the second layer, and the third layer.

  In the mask, at least one of the first layer and the third layer may have a smaller coefficient of friction than the second layer. In this case, for example, by forming a layer having a smaller friction coefficient than the second layer among the first layer and the third layer on the inner side in contact with the face, for example, the slip with the face becomes better A good mask can be formed. Also, for example, the mask main body portion may be formed by forming a layer having a smaller friction coefficient than the second layer among the first layer and the third layer to form a mask having a slippery outer surface. it can.

  In the mask, the mask body portion is formed by integrally cutting the first layer, the second layer, and the third layer of the bonding sheet while conveying the long bonding sheet. You may In this case, after cutting the first layer, the second layer and the third layer in separate steps, the number of manufacturing steps is reduced and the cost is reduced compared to the case where the first layer, the second layer and the third layer are joined. A reduced mask can be provided.

  The mask is formed by crossing a central position in the longitudinal direction, forming a wire provided on one end of the mask main body in the width direction, and bending a part of the mask main body, And a first joint portion joining the bent portions.

  In this case, since the mask straddles the central position in the longitudinal direction and includes the wire on one end side in the width direction of the mask main body, the wire may be deformed along the face to improve adhesion with the face. it can. In addition, since the wire is covered by a bent portion formed by a part of the first layer, the second layer, and the third layer, the mask has elasticity even in the portion covering the wire and reduces the number of parts and the number of manufacturing steps. be able to.

  The mask straddles the central position in the longitudinal direction, and a wire provided on one end of the end portion in the width direction of the mask main body, and a cover material having elasticity and covering the wire And a second joint portion joining the cover material.

  In this case, since the mask straddles the central position in the longitudinal direction and includes a wire on one end side in the width direction of the mask body, the wire is deformed along the face to improve the adhesion between the mask and the face. be able to. In addition, since the wire is covered by a stretchable cover material, the mask also has stretchability in the portion covering the wire.

  In the mask, one of the end portions in the width direction at the center position in the longitudinal direction may have a protruding portion protruding in the width direction. In this case, since the mask main body has the projection projecting in the width direction, when the mask is worn on the face, the adhesion to the face can be improved while covering the nose portion.

  In the mask, one of the end portions in the width direction at the center position in the longitudinal direction may have a protruding portion protruding in the width direction, and the wire may be disposed in the protruding portion .

  In this case, the wire can be deformed along the nose when the mask is worn on the face by arranging the wire on the protruding portion that protrudes in the width direction. Thus, the mask can improve the adhesion to the face while covering the nose.

  In the mask, the bonding sheet may be obtained by bonding the first layer and the second layer over the entire surface, and bonding the second layer and the third layer over the entire surface. In this case, since the mask main body joins the first layer and the second layer over the entire surface and joins the second layer and the third layer over the entire surface, the first layer is expanded when the mask is expanded or contracted. And the second layer, and the second layer and the third layer can be prevented from being wrinkled by forming a gap.

  The mask includes a fourth layer provided between the first layer and the second layer or between the second layer and the third layer in a region across the central position in the longitudinal direction, The first layer and the second layer, or the second layer and the third layer may be joined with the fourth layer interposed therebetween.

  In this case, since the fourth layer is provided in the region across the center position in the longitudinal direction, the first layer, the second layer, and the fourth layer are formed in portions where the mask covers at least one of the mouth and the nose when the mask is attached. It is possible to provide a mask comprising a fourth layer having a material different from that of the three layers.

  The mask includes a fourth layer provided between the first layer and the second layer or between the second layer and the third layer in a region across the central position in the longitudinal direction, The first layer and the second layer, or the second layer and the third layer are joined with the fourth layer interposed therebetween, and the first layer and the second layer interposed the fourth layer, or the same The second layer and the third layer partially have non-junction regions which do not bond to each other, and the non-junction region is a region including all of the fourth layer and wider than the fourth layer, and The end in the width direction of the non-bonding region is a range closer to the center in the width direction than the end in the width direction of the mask body portion, and the first layer and the fourth layer sandwiching the fourth layer The two layers or the second layer and the third layer may be joined in a junction region other than the non-junction region.

  In this case, since the fourth layer is not joined to the first layer and the second layer, or the second layer and the third layer, the fourth layer may be made of a material having no stretchability. It does not prevent the first layer, the second layer, and the third layer from stretching and contracting. Therefore, the mask can be provided with stretchability while having the function of the material of the fourth layer.

  The fourth layer of the mask may comprise a filter material. In this case, the mask can be made more dustproof.

  The third layer of the mask may include a moisturizing agent or an antibacterial agent at least in a region across the central position in the longitudinal direction. In this case, since the third layer contains a moisturizing agent or an antibacterial agent, the moisturizing agent or the antibacterial agent can be held longer.

  In the mask, the first layer and the third layer may include at least one material of a woven fabric, a knitted fabric, and a first non-woven fabric. In this case, the mask can be provided with a color or a pattern while the first layer or the third layer has elasticity.

  In the mask, the first nonwoven fabric in the first layer or the third layer may be manufactured by a spun bond method or a thermal bond method. In this case, since the first layer or the third layer is formed of the first non-woven fabric manufactured by the process having elasticity, it has elasticity and can be colored or patterned.

  The second layer of the mask may comprise a foam or a second non-woven material. In this case, the second layer has elasticity and can increase elasticity.

  The foam in the second layer of the mask may comprise a polyurethane or polyester material. In this case, the second layer has higher elasticity and can further increase the elasticity to the face.

  The second nonwoven fabric in the second layer of the mask may be manufactured by a needle punch method. In this case, since the second layer is a second non-woven fabric manufactured by a manufacturing method having higher elasticity, it has higher elasticity and can further increase the elasticity to the face.

  The first layer and the third layer of the mask may have the same material. In this case, the first layer and the third layer can have the same function and appearance, and the appearance becomes better. Also, since either the first or third layer can be in contact with the face, the user can use it in a reversible manner.

  The first layer and the third layer of the mask may have different materials. In this case, the first layer and the third layer can have different functions.

  The second layer of the mask may comprise a different material than the first and third layers. In this case, the material of the second layer is not exposed to the outside which is the inner surface and the outer surface opposite to the face. For example, even if the material of the second layer is a material for enhancing the stretchability, if the appearance is not good in appearance, by covering the first layer and the third layer with materials different from the second layer, You can look good.

  The mask manufacturing method according to the second aspect of the present invention includes a covering portion covering a part of the face including the mouth, and a direction connecting the ear hooks formed on both ends is a longitudinal direction, which is orthogonal to the longitudinal direction Mask having the covering direction and the ear hooking portion, wherein the mask body is formed by a bonding sheet which is a sheet to which the first layer, the second layer, and the third layer are bonded. The first layer, the second layer, and the third layer are all made of a stretchable material, and the third layer is adjacent to the second layer and opposite to the first layer. A mask manufacturing method for manufacturing a mask bonded to the side, and at least two layers of the first layer, the second layer, and the third layer are materials formed by different kinds of materials or manufacturing methods from each other And using a cutting device, the first of the joining sheets The second layer, and cutting the third layer in the same step may include a cutting step of forming the mask body. In this case, since the first layer, the second layer, and the third layer are cut in the same step, the manufacturing time can be shortened. Conventionally, in order to form a three-dimensional shape, it is necessary to separate the vicinity of the central position in the longitudinal direction of the mask main body in advance, and to perform another bonding step of bonding the inner surface and the inner surface to each other. Another bonding step has resulted in an increase in manufacturing time. However, since the mask body can be formed by cutting the first layer, the second layer, and the third layer in the same process, the mask manufacturing time can be shortened.

  In the mask manufacturing method, the first layer and the third layer have a smaller coefficient of friction than the second layer, and the cutting step is carried by the carrying device in contact with at least the first layer or the third layer. The bonded sheet may be cut. In this case, since the joined sheet is conveyed by the conveying device in contact with the first layer or the third layer having a smaller coefficient of friction than the second layer, the conveyance of the joined sheet is smooth and good cutting can be performed.

  In the mask manufacturing method, the cutting device includes a rotating body having a cutting blade on a cylindrical outer peripheral surface, and a receiving table at a position facing the bonding sheet with the bonding sheet interposed therebetween; One of the layer and the third layer is in contact with the cradle, the other is opposed to the rotating body, and in the cutting process, the bonding is performed by rotating the rotating body while pressing in the direction of the pedestal. The sheet may be cut while being conveyed. In this case, since the bonding sheet is cut while being conveyed, the number of manufacturing steps can be reduced.

  In the mask manufacturing method, a wire disposing step of disposing a wire on one end side in the width direction across the central position in the longitudinal direction, and covering the wire disposed in the wire disposing step And forming a bent portion covering the wire by bending a part of the bonding sheet, and forming a bent portion bonding step.

  In this case, in addition to the effect of the mask manufacturing method, a mask in which a wire is arranged can be manufactured by a bent portion formed by bending a part of the bonding sheet.

  Hereinafter, an embodiment of a mask 1 embodying the present invention will be described with reference to the drawings. Note that the drawings to be referred to are used to explain the technical features that can adopt the present invention, and the present invention is not limited thereto.

  In the following description, the mask 1 shown in FIG. 1 may be referred to as a mask 1A. Further, the mask 1 shown in FIG. 4 may be referred to as a mask 1B. Further, as shown in FIG. 1, a direction connecting the ear hooks 3 formed on both ends is taken as a longitudinal direction, and a direction orthogonal to the longitudinal direction is taken as a width direction. The center in the longitudinal direction is taken as the center position C in the longitudinal direction.

  FIG. 1 is a view of the mask 1 as viewed from the side of the third layer 12 which is the inner side in contact with the face. Moreover, FIG. 2 is the figure which looked at the mask 1 from the side of the 1st layer 10 which is an outer side. The mask 1 includes a mask main body 2 having a covering portion 4 covering a part of the face including the mouth and ear hooks 3 formed on both end sides in the longitudinal direction. The longitudinal end 72 of the ear hook 3 has an arc shape. In the ear hooking portion 3, the hole 71 to be put on the ear has an elliptical shape, and the major axis of the elliptical shape is along the longitudinal direction of the mask 1. In the mask 1 shown in FIG. 1, the holes 71 have parallel portions along the long axis direction, but the invention is not limited thereto. The hole 71 may have an elliptical shape not having a parallel portion along the long axis direction. The mask body 2 has substantially the same widthwise dimension along the longitudinal direction except for the longitudinal end 72 of the ear hook 3. However, as described later (see FIG. 8), the dimensions in the width direction may not be equal. It can be deformed depending on the application of the mask. The mask main body 2 is integrally formed of a bonding sheet 50 which is a sheet to which the first layer 10, the second layer 11, and the third layer 12 are bonded (see FIGS. 3 and 4). At least two of the first layer 10, the second layer 11, and the third layer 12 are materials formed by different types of materials or manufacturing methods. The mask body 2 has a substantially symmetrical shape with respect to the central position C in the longitudinal direction.

  FIG. 3 is a sectional view taken along line AA in FIG. The bonding sheet 50 forming the mask main body 2 is a sheet obtained by bonding the first layer 10, the second layer 11, and the third layer 12. As shown in FIG. 1 and FIG. 3, the wire 80 is disposed along the longitudinal direction across the central position C in the longitudinal direction. More specifically, the wire 80 is disposed so as to be substantially symmetrical with respect to the central position C in the longitudinal direction. As shown in FIG. 3, the mask 1 </ b> A includes a bent portion 5 and a first bonding portion 15. The bent portion 5 is formed by bending the bonding sheet 50 inward. The bent portion 5 covers the wire 80. The first bonding portion 15 is a portion for bonding the bending portion 5 to the third layer 12. The first bonding portion 15 is provided on at least a part of the periphery of the wire 80 (in the present embodiment, as an example, the width direction outer side and the longitudinal direction outer side of the wire 80).

  FIG. 4 is a sectional view taken along line AA in FIG. 1 and shows an example different from the structure shown in FIG. In the following description, the mask 1 shown in FIG. 4 may be referred to as a mask 1B. The mask 1 </ b> B includes a cover material 13 and a second bonding portion 112. The cover material 13 covers the wire 80. The cover material 13 is a member different from the bonding sheet 50, and has elasticity. The second bonding portion 112 is a portion for bonding the cover material 13 to the third layer 12. The second joint portion 112 is provided on at least a part of the periphery of the wire 80 (in the present embodiment, as an example, the width direction outer side and the longitudinal direction outer side of the wire 80).

  FIG. 5 summarizes examples of the material of the first layer 10 and the third layer 12. The material of the first layer 10 and the third layer 12 can be selected from a plurality of types. Further, as the materials of the first layer 10 and the third layer 12, different materials may be selected from the materials shown in FIG. 5 or the same material may be selected. The material of the first layer 10 and the third layer 12 can be selected from woven fabric, woven fabric and non-woven fabric (first non-woven fabric 91). The dough includes cut free dough. Fabric, which is a type of material of the first layer 10 and the third layer 12, is a fabric made by combining yarns in all directions. The characteristics of the fabric are that it has stretchability and a high-class feeling. Moreover, a textile can give a color, a pattern, etc.

  Another type of material for the first layer 10 and the third layer 12 is knit. A knit is a fabric made by forming a continuous loop in the latitudinal or longitudinal direction. The characteristic of knit is that it is rich in stretchability and drape. The knit fits gently into the three-dimensional human body and movement. In addition, the knit is freely assignable to colors, patterns, etc. and can be imparted to colors, patterns, etc. Furthermore, the antimicrobial agent 16 and the moisturizing agent 14 can be provided and scented. Examples of the antimicrobial agent 16 include those made of silver, charcoal and minerals. Moreover, as an example of the moisturizing agent, what the collagen, ceramide, and the vitamin were mix | blended is mentioned. One type of knit is tricot fabric. Tricot fabric is one type of fabric in warp knitting and is produced by a tricot knitting machine. The characteristics of Tricot fabric are that it has good shape stability and little change in shape after washing, it has a soft texture and excellent fit, and it has a porous structure that resists wrinkles and creases, etc. is there.

  Yet another type of material of the first layer 10 and the third layer 12 is a first non-woven fabric 91 (see FIGS. 3 and 4). In order to distinguish from the nonwoven fabric of the second layer 11 described later, the nonwoven fabric of the first layer 10 and the third layer 12 is referred to as a first nonwoven fabric 91. The first non-woven fabric 91 is manufactured by the spun bond method or manufactured by the thermal bond method. The characteristic of the spunbonded nonwoven fabric is that it is thin but soft and strong. The non-woven fabric by the spun bond method is hygienic without using an adhesive resin because it is manufactured by thermocompression bonding. In addition, the non-woven fabric by the spun bond method is excellent for mass production due to the simple process of hot roll welding of long fibers by direct spinning. A feature of the thermal bond non-woven fabric is that it is hygienic because it does not use an adhesive. Moreover, the nonwoven fabric by a thermal bond method has a soft texture.

  The material of the first layer 10 and the third layer 12 is, for example, nylon, polyester, polyurethane and the like. Besides this, it is possible to select materials that exhibit similar characteristics. Among the materials of the first layer 10 and the third layer 12, for example, the coefficient of friction of a knit is generally 0.1 to 0.3 when the object is a metal. Moreover, in the case of the nonwoven fabric by a spun bond method, 0.2 to 0.4 is general, when object is a metal. All the materials shown in FIG. 5 have higher durability when washed than the materials shown in FIG. 6 described later.

  FIG. 6 shows an example of the inner material which is the second layer 11. The material of the second layer 11 can be selected from a plurality of types. One type of material of the second layer 11 is a foam. Although a foamed article uses polyurethane, polyester, etc. as a material, you may use the other material with the same characteristic. The foamed product has a polyol and a polyisocyanate as main components. The foamed product is formed by mixing a foaming agent, a foam control agent, a catalyst, a coloring agent and the like and resinifying it. The characteristics of the foamed product are that it has excellent elasticity performance and good adhesion to the face. For example, the coefficient of friction of the foamed polyurethane is generally 0.4 to 0.8 when the object is metal.

  Another material of the second layer 11 is a second non-woven fabric 92 (see FIGS. 3 and 4). In order to distinguish it from the nonwoven fabric of the first layer 10, a second nonwoven fabric 92 is used. The second non-woven fabric 92 is manufactured by a needle punch method. The feature of the nonwoven fabric by the needle punch method is that the durability and the strength are strong. In addition, the non-woven fabric by the needle punching method has a soft and flexible texture. Examples of materials are synthetic fibers such as polyester, polypropylene and rayon, chemical fibers, and natural fibers such as cotton. In the needle punching method, fibers are mechanically entangled by processing a web made by a carding machine into a non-woven fabric by piercing a needle with a protrusion, which is called a barb, several tens of times / cm 2 (square centimeters) or more It is a manufacturing method. The non-woven fabric by the needle punch method changes the texture and the coefficient of friction depending on the shape of the needle (thickness and shape of the barb, etc.), needle puncture density (number of sticks per unit area) and needle depth (depth of needle puncture).

  The first layer 10, the second layer 11, and the third layer 12 make the coefficient of friction of the first layer 10 and the third layer 12 smaller than the coefficient of friction of the second layer 11 depending on the type of material and the selection of the manufacturing method. be able to. For example, assuming that the first layer 10 and the third layer 12 are knitted and the second layer 11 is a foamed polyurethane, the coefficient of friction against metal is larger for the foamed polyurethane, so the coefficient of friction of the first layer 10 and the third layer 12 Is smaller than the coefficient of friction of the second layer 11.

  In the case of the first layer 10, the second layer 11, and the third layer 12 described above, the design property can be improved by attaching a color, a pattern, or the like to the mask 1 in the first layer 10 and the third layer 12. it can. In the second layer 11, a more stretchable or elastic material can be used. Since the first layer 10, the second layer 11, and the third layer 12 are all made of a stretchable material, the mask 1 is stretchable.

  FIG. 7 shows that the mask 1 contains either the second layer 11 or the third layer 12 as follows. A second layer 11 or a third layer 12 containing a humectant 14. One containing the antibacterial agent 16 in the second layer 11 or the third layer 12. Alternatively, the second layer 11 or the third layer 12 contains the moisturizer 14 and the antibacterial agent 16 in combination. In the following description, the mask 1 shown in FIG. 7 may be referred to as a mask 1C. As shown in FIG. 7, the moisturizer 14 is included in the second layer 11 or the third layer 12 of the covering portion 4 in a predetermined range 73 across the center position C in the longitudinal direction. Alternatively, the second layer 11 and the third layer 12 contain the antibacterial agent 16. Alternatively, the second layer 11 and the third layer 12 include the humectant 14 and the antibacterial agent 16 in combination. In FIG. 7, a predetermined range 73 is a range surrounded by an alternate long and short dash line. The predetermined area 73 in which the moisturizer 14 or the antibacterial agent 16 is contained is an area covering the nose and the periphery of the mouth when the mask 1 is worn.

  FIG. 8 shows a mask 1 D which is an example of the mask 1. The mask 1D has a protrusion 20 and a protrusion 21 whose end in the width direction further protrudes in the width direction at a central position C in the longitudinal direction, as compared to the mask 1A. The wire 80 is disposed in the protrusion 20. The protrusion 20 is a portion that hits the nose when the mask 1 is worn. Since the wire 80 is at the protrusion 20, it can deform along the shape of the nose. A protrusion 21 is also provided on the opposite side in the width direction with respect to the protrusion 20. The protrusion 21 is a portion that hits the jaw when the mask 1 is attached.

  Next, a method of manufacturing the mask 1 in the above embodiment will be described. FIG. 9 is a schematic view showing a production facility and a production process of the mask 1. As shown in FIG. 9, the manufacturing process of the mask 1 includes a bonding process S1, a cutting process S2, a wire arranging process S3, and a bending portion forming process S4. In the bonding step S1, the cutting step S2, the wire arranging step S3, and the bending portion forming step S4, the first layer 10, the second layer 11, the third layer 12, and the bonding sheet 50 are transported by the transport device 34 described later. While being executed.

  As shown in FIG. 9, the bonding step S <b> 1 is a step of bonding the first layer 10, the second layer 11, and the third layer 12 by the bonding device 31. The bonding method will be described by taking frame laminating as an example. Two burners 70 heat the first layer 10 and the third layer 12 on the upstream side of the pair of rollers 35. By heating and melting the first layer 10 and the third layer 12 in contact with the second layer 11, the pair of rollers 35 press and rotate in the direction of the arrow 74 to convey the first layer 10, the second layer The layer 11 and the third layer 12 are joined to form a joined sheet 50. When the first layer 10, the second layer 11, and the third layer 12 are bonded on the entire surface, the two burners 70 heat the entire surfaces of the first layer 10 and the third layer 12, respectively. When the first layer 10, the second layer 11, and the third layer 12 are partially joined, the two burners 70 heat the area to be joined to the first layer 10 and the third layer 12, respectively.

  Although the example which manufactures the joining sheet 50 by joining process S1 was shown in this embodiment, it does not restrict to this. A bonding sheet 50 in which the first layer 10, the second layer 11, and the third layer 12 are bonded may be prepared in advance, and the bonding step S1 may be omitted. When there is the bonding step S <b> 1, the pair of rollers 35 is a part of the bonding device 31. When the bonding step S1 is omitted, the pair of rollers 35 serves as an introduction device 42 for the bonding sheet 50. In this case, the introducing device 42 introduces the bonding sheet 50 into the cutting device 32.

  The cutting step S2 is a step of cutting the bonding sheet 50 conveyed by the conveying device 34 described later to the cutting device 32 into a mask shape. The cutting device 32 will be described in two examples shown in FIGS. 10 and 11. The cutting device 32 shown in FIG. 10 has a structure in which the bonding sheet 50 is held between the rotating body 38 provided with the cutting blade and the pedestal 39 on the outer peripheral surface of the cylindrical member. The rotating body 38 rotates while pressing the bonding sheet 50 in the direction of the receiving table 39, and cuts the bonding sheet 50 into a mask shape. The cutting device 32 shown in FIG. 11 has a structure in which a flat plate 40 is provided with a cutting blade, and the plate 40 operates in the direction of the receiving stand 39 with the bonding sheet 50 interposed therebetween for cutting.

  The wire arrangement step S3 is a step of arranging the wire 80 in the wire arrangement device 33. The wire arrangement step S3 is the following procedure. As shown in FIG. 12A, the wire 80 is disposed on the mask main body 2 on the bonding sheet 50. Although not shown, the wire placement device 33 includes a wire feeding device for feeding the wires 80 one by one. Alternatively, the wire 80 may be manually disposed without using the wire supply device.

  In the bending portion forming step S4, as shown in FIG. 12 (b), the bending portion 5 of the outer shape of the mask main body 2 cut in the cutting step S2 is bent to cover the wire 80, and It is a process of joining. The first bonding portion 15 in which the bending portion 5 and the third layer 12 of the mask main body 2 are in contact with each other welds the bending portion 5 and the third layer 12 in a spot manner. If welding is performed by avoiding the wire 80, the wire 80 does not weld to the first layer 10, the second layer 11, and the third layer 12. The wire 80 uses, for example, a resin material that does not normally expand and contract such as a polyethylene material, a metal material, and the like. Even if the wire 80 is disposed, the first layer 10, the second layer 11, and the third layer 12 can expand and contract. One example of a welding method is ultrasonic welding. A cross-sectional view of the state where the wire 80 is disposed is shown in FIG.

  Although the form of the mask 1A shown in FIG. 3 has been described in the above-mentioned bent portion forming step S4, in the case of the mask 1B shown in FIG. The mask 1 </ b> B uses the cover material 13 instead of using the bent portion 5. Instead of the step of bending the bent portion 5 to cover the wire 80, the cover material 13 covering the wire 80 is attached, and the cover material 13 and the third layer 12 are welded at the second bonding portion 112.

  As shown in FIG. 9, the conveyance device 34 includes a conveyance roller 36 and a sheet receiving table 37. The transport roller 36 contacts the third layer 12 of the bonding sheet 50 and rotates in the direction of the arrow 75 to transport the bonding sheet 50. The first layer 10 of the bonding sheet 50 moves while sliding on the sheet support 37. Since the first layer 10 has a small coefficient of friction with the sheet support 37 made of metal, resin or the like, the bonding sheet 50 smoothly moves on the sheet support 37. In the example of FIG. 9, the transport device 34 is located at the most downstream side in the transport direction of the bonding sheet 50, but the present invention is not limited to this position. For example, the conveying device 34 may be positioned upstream of the cutting device 32 and the bonding sheet 50 may be pushed out to the cutting device 32. Furthermore, the transport device 34 may be located not only at one location but at multiple locations.

  Although not shown, when the second layer 11 or the third layer 12 of the mask 1C is impregnated with the moisturizer 14, a moisturizer impregnation step is provided. Alternatively, in the case where the second layer 11 and the third layer 12 are impregnated with the moisturizer 14, a moisturizer impregnation step is provided. The moisturizing agent impregnation step may be performed anywhere before or after the cutting step S2 and before or after the bending portion forming step S4. Furthermore, in the case where the antibacterial agent 16 is applied to the second layer 11 or the third layer 12 of the mask 1C, an antibacterial agent applying step is provided. Alternatively, in the case where the antimicrobial agent 16 is applied to the second layer 11 and the third layer 12, an antimicrobial agent applying step is provided. The antimicrobial agent applying step may be performed anywhere before or after the cutting step S2 and before or after the bending portion forming step S4, as in the moisturizing agent impregnating step.

  FIG. 13 is a view showing the state of the bonding sheet 50 in each manufacturing process of the mask 1 shown in FIG. FIG. 13A is a view in which the first layer 10, the second layer 11, and the third layer 12 are joined to form a joined sheet 50. FIG. FIG. 13 (b) is a plan view of the bonding sheet 50. FIG. 13C shows a state in which the bonding sheet 50 passes through the cutting device 32 and the cutting device 32 cuts the bonding sheet 50 into the shape of the mask 1. FIG. 13D shows the mask 1 in which the wire 80 is disposed and the bent portion 5 is formed. The plurality of masks 1 can be continuously manufactured in a series of steps on the bonding sheet 50 formed on a long sheet by the manufacturing equipment and the manufacturing process described above.

  The manufacturing method of the mask 1 described above is also applicable to the mask 1C, the mask 1D, and the mask 1E and the mask 1F described later.

  Next, a mask 1E which is the mask 1 according to the modification will be described. As shown in FIG. 14, the fourth embodiment differs in that a fourth layer 60 is added to the mask 1A (see FIG. 1). The inside of the broken line R is a view in which the third layer 12 is peeled off to represent the fourth layer 60. Or it is the figure which peeled off the 2nd layer 11 and the 3rd layer 12 in order to represent the 4th layer 60. FIG. Further, in FIG. 14, the same parts as those in the above embodiment are denoted by the same reference numerals, and the description thereof will be omitted.

  The mask 1E is provided with a fourth layer 60 in a region straddling the central position C in the longitudinal direction. FIG. 15 is a cross-sectional view taken along line E-E in FIG. A bonding sheet 500 bonded to the entire surface with the fourth layer 60 interposed between the second layer 11 and the third layer 12 is used. Although not shown, the fourth layer 60 may be provided between the first layer 10 and the second layer 11.

  The fourth layer 60 uses a filter material. The filter material is made of a material that improves dust resistance, and has a size limited around the nose and mouth. The filter material has high dust resistance compared to the first layer 10 and the second layer 11. The filter material is generally a material having poor stretchability, and if the fourth layer 60 is sandwiched between the first layer 10 and the second layer 11 in a wide range and joined, the stretchability of the mask 1E is lost. As an example of the filter material, a polypropylene melt-blown non-woven fabric is used.

  Next, a mask 1F according to a modification of the mask 1 will be described. As shown in FIG. 16, a difference is that a non-junction region 61 is provided around the fourth layer 60 with respect to the mask 1E (see FIG. 14). In FIG. 16, the same parts as those in the above embodiment are denoted by the same reference numerals, and the description thereof will be omitted.

  Similar to the mask 1E, the mask 1F includes the fourth layer 60 in a region across the central position C in the longitudinal direction. The mask 1F has a junction region 62 indicated by hatching crossing the non-junction region 61 as described later. The non-junction region 61 is wider than the fourth layer 60. The region in the width direction of the non-bonding region 61 is a range on the center side in the width direction than the end in the width direction of the mask 1F. That is, at the width direction end of the mask 1F, there is a bonding region 62 so as to surround the fourth layer 60. Therefore, the fourth layer 60 does not protrude or protrude from the mask 1F.

  FIG. 17 is a cross-sectional view taken along line F-F in FIG. The second layer 11 and the third layer 12 sandwich the fourth layer 60 to form a bonding sheet 600. Although not shown, the fourth layer 60 may be interposed between the first layer 10 and the second layer 11. Hereinafter, the case where the second layer 11 and the third layer 12 sandwich the fourth layer 60 will be described. Around the fourth layer 60 is a non-junction region 61, and the second layer 11 and the fourth layer 60, and the third layer 12 and the fourth layer 60 are not joined. The fourth layer 60 is movable with respect to the second layer 11 and the third layer 12 within the non-junction region 61. The second layer 11 and the third layer 12 are joined at a junction region 62. Since the second layer 11 and the third layer 12 are not joined to the fourth layer 60, even if the fourth layer 60 is a material with poor stretchability, the mask 1F has stretchability. Although FIG. 17 is a cross-sectional view of the mask 1F cut in the longitudinal direction, the non-bonding region 61 is provided all around the fourth layer 60 including the width direction. The first layer 10 and the second layer 11 are also joined in the non-junction region 61.

  Next, a method of manufacturing the mask 1E and the mask 1F will be described. FIG. 18 is a schematic view showing a manufacturing apparatus and manufacturing steps of the mask 1E and the mask 1F. The manufacturing process of the mask 1E and the mask 1F adds the attaching process S5 of the fourth layer 60 to the manufacturing process (see FIGS. 9 to 12) of the mask 1A. The same manufacturing steps as in the above embodiment are given the same reference numerals as in FIG. 10, and the description will be omitted. FIG. 19 is a view showing the state of the bonding sheet 500 and the bonding sheet 600 in each manufacturing process of the mask 1E and the mask 1F shown in FIG.

  As shown in FIG. 19A, the fourth layer 60 is attached to the second layer 11 in the attachment step S5 of the fourth layer 60 (see FIG. 18). The mounting device 41 is located upstream in FIG. 18 and mounts the fourth layer 60 at regular intervals with respect to the longitudinal direction of the bonding sheets 500 and 600. This interval is adjusted to the interval when forming the mask 1E and the mask 1F along the longitudinal direction of the bonding sheet 500 and the bonding sheet 600.

  As shown in FIG. 18, in the bonding step S <b> 1, the first layer 10, the second layer 11, and the third layer 12 are bonded by the bonding device 31. Bonding process S1 demonstrates a frame lamination process to an example. Two burners 70 heat the first layer 10 and the third layer 12 on the upstream side of the pair of rollers 35. The heated and melted first layer 10 and the third layer 12 are in contact with the second layer 11, and the pair of rollers 35 press and convey the sheet, whereby the first layer 10, the second layer 11, and the third layer The layer 12 is joined to form a joined sheet 500 or a joined sheet 600.

  When manufacturing the mask 1E, the two burners 70 heat the entire surface of the first layer 10 and the third layer 12, respectively. The heated and melted first layer 10 is in contact with one side of the second layer 11, and the third layer 12 is in contact with the other side of the second layer 11 on which the fourth layer 60 is mounted, and the pair of rollers The sheet 35 is conveyed while being pressed. The first layer 10, the second layer 11, the fourth layer 60, and the third layer 12 are bonded on the entire surface to form a bonding sheet 500. The first layer 10, the second layer 11, the fourth layer 60, and the third layer 12 can be partially joined. In that case, the two burners 70 heat the area joined to the first layer 10 and the third layer 12, respectively.

  When manufacturing the mask 1F, a part of bonding process S1 differs from the case of the mask 1E. The burner 76 avoids the non-bonding area 61 so as to form a non-bonding area 61 which is wider than the area in which the fourth layer 60 is arranged when the third layer 12 contacts the second layer 11 Do. The burner 70 heats the entire surface of the first layer 10. The heated and melted first layer 10 is in contact with one side of the second layer 11, and the third layer 12 is in contact with the other side of the second layer 11 on which the fourth layer 60 is mounted, and the pair of rollers The sheet 35 is conveyed while being pressed. One side of the third layer 12 and the second layer 11 is joined except for the fourth layer 60 and the non-junction region 61 around it, and the other side of the first layer 10 and the second layer 11 is entirely joined To form a bonding sheet 600. The cutting step S2, the wire arranging step S3, and the bending portion forming step S4 are the same as those of the embodiment shown in FIG. It is also possible to partially bond one side of the first layer 10 and the second layer 11 and the other side of the third layer 12 and the second layer 11. In that case, the burner 70 heats the area joining to one side of the second layer 11 with respect to the first layer 10, and the burner 76 joins with the other side of the second layer 11 with respect to the third layer 12 Heat the area.

  The mask 1 described above has various effects. As shown in FIG. 1, the mask 1 is provided with a covering portion 4 covering a part of the face including the mouth, and a direction connecting the ear hooks 3 formed on both ends is a longitudinal direction, and a direction orthogonal to the longitudinal direction In the width direction. Also, as shown in FIG. 3 to FIG. 6, a joined sheet 50 which is a sheet including the covering portion 4 and the ear hooked portion 3 and in which the first layer 10, the second layer 11 and the third layer 12 are joined. The mask main body 2 is formed by the sheet 500 and the bonding sheet 600. The first layer 10, the second layer 11, and the third layer 12 are all made of a stretchable material. The third layer 12 is joined adjacent to the second layer 11 and opposite to the first layer 10. At least two of the first layer 10, the second layer 11, and the third layer 12 are materials formed by different types of materials or manufacturing methods.

  In this case, the mask main body 2 including the covering portion 4 and the ear hooking portion 3 is formed by the joining sheet 50 which is a sheet to which the first layer 10, the second layer 11, and the third layer 12 are joined. . At least two of the first layer 10, the second layer 11, and the third layer 12 are materials formed by different types of materials or manufacturing methods. Therefore, the mask main body 2 has a function according to the other functions, that is, the materials of the first layer 10, the second layer 11, and the third layer 12, in addition to the stretchability.

  For example, the designability can be improved by attaching a color, a pattern, or the like to the first layer 10 and the third layer 12. In the second layer 11, the stretchability and elasticity of the mask 1 can be improved by using a more stretchable material. In the above embodiment, as shown in FIG. 5, the first layer 10 and the third layer 12 have stretchability and can be freely imparted with colors and patterns, thus providing the mask 1 rich in fashion. can do. In addition, since the first layer 10 and the third layer 12 have a good touch and fit, when the third layer 12 is in contact with the face with the mask 1 attached, a good wearing feeling can be obtained. Furthermore, the first layer 10 and the third layer 12 have high durability when washed as compared with the material of the second layer 11. Since the first layer 10 and the third layer 12 sandwich the second layer 11, the mask 1 has high durability when it is washed. As shown in FIG. 6, the second layer 11 is excellent in elasticity and stretchability, and by providing the second layer 11 between the first layer 10 and the third layer 12, the mask 1 has elasticity and There is an effect that elasticity becomes high. In the mask 1, the first layer 10 and the third layer 12 are formed in three layers sandwiching the second layer 11, and washing is performed while taking advantage of the advantages of the second layer 11 (the point that the elasticity and stretchability are excellent). It is a mask with improved durability when

  Conventional masks need to sacrifice design properties such as color and pattern if importance is attached to the face, and conversely, adherence to the face, which is the original function of the mask, is sacrificed if emphasis is placed on design. I needed to. The mask 1 is a mask having both design and elasticity and elasticity, which are functions that the mask is originally required. Further, since each of the first layer 10, the second layer 11, and the third layer 12 is made of a material having stretchability, the mask 1 has stretchability.

  Further, in the mask 1, at least one of the first layer 10 and the third layer 12 has a smaller coefficient of friction than the second layer 11. Therefore, by forming the layer having a smaller coefficient of friction than the second layer 11 of the first layer 10 and the third layer 12 on the inner side in contact with the face, the mask body 2 improves the slippage with the face and the touch Good mask 1 can be formed. In the present embodiment, the third layer 12 having a smaller coefficient of friction than the second layer 11 is formed on the inside in contact with the face.

  Further, the mask main body portion 2 forms the mask 1 having the slippery outer surface by forming the layer having a smaller friction coefficient than the second layer 11 out of the first layer 10 and the third layer 12. be able to. Since the outer surface is slippery, the user who wears the mask 1 feels good when touching the mask 1. In the present embodiment, the first layer 10 having a smaller coefficient of friction than the second layer 11 forms the outer surface of the mask 1.

  As shown in FIGS. 9 to 12, the mask body 2 in the mask 1 transports the long bonding sheet 50 while the first layer 10, the second layer 11, and the third layer 12 of the bonding sheet 50. By cutting it integrally. The mask body 2 is formed by cutting continuously along the longitudinal direction of the long bonding sheet 50.

  In this case, as compared with the case where the first layer 10, the second layer 11, and the third layer 12 are joined after the first layer 10, the second layer 11, and the third layer 12 are cut in separate steps, It is possible to provide the mask 1 with a reduced number of manufacturing steps and reduced costs. Since the number of manufacturing steps is reduced, the mask 1 can be manufactured in large quantities. In addition, since mass production can be performed with one production facility, production volume can be secured without introducing a new production facility.

  As shown in FIG. 3, the mask 1A (also the masks 1C, 1D, 1E, and 1F) straddles the central position C in the longitudinal direction, and includes the wire 80 on one end side in the width direction. Furthermore, the mask 1A (the masks 1C, 1D, 1E, 1F are also the same) is formed by bending a part of the mask main body 2, and the bending portion 5 covering the wire 80 and the bending portion 5 And a first joint 15 joined to the

  In this case, since the mask 1A (the masks 1C, 1D, 1E, 1F also crosses the central position C in the longitudinal direction and includes the wire 80 on one end side in the width direction), the wire 80 along the face It can be deformed to improve adhesion to the face. In addition, since the wire 80 is covered by the bent portion 5 formed of a part of the first layer 10 and the second layer 11, the mask 1A (the masks 1C, 1D, 1E, 1F are the same) also covers the wire 80 While having elasticity, the number of parts and the number of manufacturing steps can be reduced.

  As shown in FIG. 4, the wire 80 may have another arrangement. The mask 1B has a wire 80 provided at the end of one of the end portions in the width direction, the center portion C in the longitudinal direction, a cover member 13 having elasticity and covering the wire 80, and a cover member And a second joint 112 joining the second layer 11 to the second layer 11.

  In this case, since the mask 1B straddles the central position C in the longitudinal direction and includes the wire 80 on one end side in the width direction, the wire 80 is deformed along the face to improve the adhesion between the mask 1B and the face It can be done. Although the wire 80 does not have stretchability, since the cover material 13 having stretchability covers it, the mask 1 </ b> B also has stretchability in the portion covering the wire 80. In addition, since the cover material 13 can be made of a thin material, the wire 80 can be disposed without making large unevenness on the inner side surface of the mask 1B. When the user wears the mask 1B, the adhesion to the face is improved. Furthermore, since the cover material 13 is a component separate from the bonding sheet 50, the bonding sheet 50 can have the minimum width dimension required for the mask main body 2, and the material cost can be reduced.

  As shown in FIG. 8, one end of the mask 1 D in the width direction at the center position C in the longitudinal direction has a protrusion 20 and a protrusion 21 protruding in the width direction. The protrusion 20 at one end is a portion that covers the nose when the user wears the mask 1D. Since the protrusion 20 covers the nose, when the user wears the mask 1D, the mask 1D fits the face including the nose. The protrusion 21 may be provided on the opposite side in the width direction with respect to the protrusion 20. The protrusion 21 is a portion that hits the jaw when the mask 1D is attached. Since the protrusions 21 cover the jaws, when the user wears the mask 1D, the mask 1D fits more on the face.

  When a mask having stretchability is stretched in the longitudinal direction, the dimension in the width direction tends to decrease as the stretch. In particular, the central position C in the longitudinal direction is a portion covering the nose and the mouth, and when the dimension in the width direction becomes short, the nose and the mouth can not be covered. However, the mask 1D shown in FIG. 8 has the protrusion 20 and the protrusion 21. The widthwise dimension at the longitudinal center position C is larger than the widthwise dimension of the other portions. Therefore, when the mask 1D is stretched in the longitudinal direction, the nose and the mouth can be covered even if the dimension in the width direction is shortened as a whole.

  Furthermore, as shown in FIG. 8, one end of the width direction at the center position C in the longitudinal direction has a protrusion 20 protruding in the width direction, and the mask 80 is a protrusion 20 for the wire 80. Place on

  In this case, by arranging the wire 80 on the projecting portion 20 protruding in the width direction, the wire 80 can be deformed along the nose when the user wears the mask 1D on the face. Thus, the mask 1D can further improve the adhesion to the face while covering the nose.

  The bonding sheet 50 or the bonding sheet 500 covers the entire surface of the first layer 10 and the second layer 11 like the masks 1A, 1B, 1C, 1D and 1E shown in FIG. 3, FIG. 4, FIG. 7, FIG. The second layer 11 and the third layer 12 are bonded over the entire surface.

  In this case, when the masks 1A, 1B, 1C, 1D, and 1E are expanded or contracted, the mask main body 2 does not have a gap between the first layer 10, the second layer 11, and the third layer 12, and wrinkles occur. It can be prevented from occurring.

  As shown in FIG. 7, the third layer 12 of the mask 1 </ b> C includes a moisturizer 14 at least in the region across the center position C in the longitudinal direction. Also, instead of the moisturizing agent 14, an antibacterial agent 16 may be provided. Alternatively, the moisturizer 14 and the antibacterial agent 16 may be included together. In this case, the mask 1 </ b> C holds the moisturizing agent 14 or the antibacterial agent 16 longer because the elastic third layer 12 includes the moisturizing agent 14 or the antibacterial agent 16.

  As shown in FIG. 5, in the mask 1, the first layer 10 and the third layer 12 have either a woven or knitted (knitted) fabric or a first non-woven fabric 91. In this case, while the first layer 10 and the third layer 12 have stretchability, the mask 1 can be colored or patterned. Since the material of the first layer 10 or the third layer 12 has a good touch, the surface of the mask 1 has a good touch. Further, since the material shown in FIG. 5 has high durability when washed, by using it for both the first layer 10 and the third layer 12 of the mask 1, it is possible to wash and provide a mask that can be repeatedly used. Furthermore, the antimicrobial agent 16 and the moisturizing agent 14 can be applied to the third layer 12 or the first layer 10, or can be scented. The tricot fabric is particularly elastic, so it is advantageous to the application of the antibacterial agent 16, the moisturizing agent 14, or the aromatization. Since the third layer 12 is in direct contact with the face of the user wearing the mask, the user can obtain an antibacterial effect, a moisturizing effect, or a relaxing effect by the scent.

  As shown in FIG. 5, the mask 1 may be one in which the first non-woven fabric 91 in the first layer 10 or the third layer 12 is manufactured by a spun bonding method or a thermal bonding method. In this case, since the first layer 10 or the third layer 12 is formed of a non-woven fabric having stretchability, it has stretchability and can be colored or patterned.

  As shown in FIG. 6, the second layer 11 of the mask 1 has a foam or a material of a second non-woven fabric 92. In this case, the second layer 11 has elasticity and can increase elasticity.

  As shown in FIG. 6, the foam in the second layer 11 of the mask 1 may have a polyurethane or polyester material. In this case, the second layer 11 has higher elasticity and can further increase the elasticity to the face.

  As shown in FIG. 6, the second non-woven fabric 92 in the second layer 11 of the mask 1 may be manufactured by a needle punch method. In this case, since the second layer 11 is the second non-woven fabric 92 manufactured by the manufacturing method having higher elasticity, it has higher elasticity and can further increase the elasticity to the face.

  The first layer 10 and the third layer 12 of the mask 1 may have the same material. In this case, the first layer 10 and the third layer 12 can have the same function and appearance, and the appearance becomes better. In addition, since either the first layer 10 or the third layer 12 can be in contact with the face, the user can use it in a reversible manner. For example, if the first layer 10 and the third layer 12 are made of materials having the same color, pattern, or the like, the mask 1 can have the same design on the inside and the outside. In addition, since one kind of material can be used for the first layer 10 and the third layer 12 in manufacturing, labor and cost for procuring the material can be saved.

  The first layer 10 and the third layer 12 of the mask 1 may have different materials. In this case, the first layer 10 and the third layer 12 can have different functions. For example, the first layer 10 may be selected as a material having design properties, and the third layer 12 may be made of a material having dust resistance or antibacterial properties, or may be provided with an antibacterial agent 16. It is possible to provide a mask with different functions on the inside and the outside.

  The second layer 11 of the mask 1 may have a different material than the first layer 10 and the third layer 12. In this case, the material of the second layer 11 is not exposed to the outside which is the outer surface opposite to the inner side in contact with the face. For example, even if the material of the second layer 11 is a material for enhancing the stretchability, the first layer 10 and the third layer 12 having a material different from that of the second layer 11 are not good in appearance. Covering can improve the appearance.

  Furthermore, the mask 1E and the mask 1F have various effects. As shown in FIGS. 14 to 17, the mask 1E and the mask 1F are between the first layer 10 and the second layer 11, or the second layer 11 and the third layer in the region across the center position C in the longitudinal direction. A fourth layer 60 is provided between the first and second layers 12, and the first layer 10 and the second layer 11, or the second layer 11 and the third layer 12 are joined with the fourth layer 60 interposed therebetween.

  In this case, since the fourth layer 60 is provided in the region across the center position C in the longitudinal direction, the first layer 10, the first layer 10, the first layer 10 in the portion where the mask 1 covers at least one of the mouth and the nose A second layer 60 may be provided which has a different material than the second layer 11 and the third layer 12. The material of the fourth layer 60 can be variously selected from materials different from those of the first layer 10 and the second layer 11.

  The mask 1F is, as shown in FIGS. 16 and 17, between the first layer 10 and the second layer 11 or between the second layer 11 and the third layer 12 in a region across the center position C in the longitudinal direction. The first layer 10 and the second layer 11 or the second layer 11 and the third layer 12 are joined with the fourth layer 60 interposed therebetween. The first layer 10 and the second layer 11 or the second layer 11 and the third layer 12 have a non-bonding region 61 which does not bond to each other in part, and the non-bonding region 61 This area is wider than the fourth layer 60 including. The end in the width direction of the non-bonding region 61 is a range closer to the center in the width direction than the end in the width direction of the mask body 2 of the mask 1F, and the first layer 10 and the second layer sandwiching the fourth layer 60 11, or the second layer 11 and the third layer 12 are joined at a junction region 62 other than the non-junction region 61.

  In this case, since the fourth layer 60 is not joined to the first layer 10 and the second layer 11 or the second layer 11 and the third layer 12, the fourth layer 60 is made of a material having no stretchability. Even if the first layer 10, the second layer 11, and the third layer 12 does not hinder the expansion and contraction. Therefore, the mask 1F can have stretchability while having the function of the material of the fourth layer 60. Further, since the end in the width direction of the non-bonding region 61 is in the range on the center side in the width direction, the fourth layer 60 can be prevented from protruding or protruding from the mask 1F when the user wears the mask 1F.

  The mask 1E and the fourth layer 60 of the mask 1F may have a filter material. In this case, the mask 1E and the mask 1F can improve dust resistance. Therefore, the mask 1E and the mask 1F impart design characteristics in terms of color, pattern, etc. in the first layer 10 and the third layer 12, have elasticity and further elasticity in the second layer 11, and The fourth layer 60 can improve the third function, that is, dust resistance. Moreover, if the material which has especially antimicrobial property as a filter raw material is used, the penetration | invasion of a virus etc. can be prevented.

  Furthermore, the method of manufacturing the mask 1 has various effects. The mask 1 has a covering portion 4 covering a part of the face including the mouth, and a direction connecting the ear hooks 3 formed on both ends of the mask 1 is a longitudinal direction, and a direction orthogonal to the longitudinal direction is a width direction Mask. The mask 1 includes a mask main body 2 formed of a sheet including a covering portion 4 and ear hooks 3 and in which a first layer 10, a second layer 11, and a third layer 12 are joined. The sheets joined are the joining sheet 50, the joining sheet 500, and the joining sheet 600 (it describes as the following joining sheet 50 grade | etc.,). Each of the first layer 10, the second layer 11, and the third layer 12 has a stretchable material. The third layer 12 is adjacent to the second layer 11 and joined to the opposite side to the first layer 10, and at least two of the first layer 10, the second layer 11 and the third layer 12 are mutually connected It is a material formed by different types of materials or manufacturing methods. As shown in FIG. 9 to FIG. 12, a mask manufacturing method for manufacturing the mask 1, using a cutting device 32, the first layer 10 such as the bonding sheet 50, the second layer 11, and the third layer 12 A cutting process S2 is performed in which the mask main body 2 is formed by cutting in the same process.

  In this case, since the first layer 10, the second layer 11, and the third layer 12 are cut in the same step, the manufacturing time can be shortened. Conventionally, in order to form a three-dimensional shape, another bonding step is required in which the central position in the longitudinal direction of the mask main body 2 is separated in advance and the inner surface and the inner surface are bonded to each other. . Another bonding step has resulted in an increase in manufacturing time. However, since the mask main body 2 can be formed by cutting the first layer 10, the second layer 11, and the third layer 12 in the same process, the manufacturing time of the mask 1 can be shortened.

  In the mask manufacturing method, the first layer 10 and the third layer 12 have a smaller coefficient of friction than the second layer 11, and the bonding sheet 50 or the like is conveyed by the conveying device 34 in contact with at least the first layer 10 or the third layer 12. In the cutting step S2, the bonding sheet 50 or the like conveyed in the conveying step may be cut.

  In this case, since the bonding sheet 50 or the like is conveyed by the conveying device 34 in contact with the first layer 10 or the third layer 12 having a smaller coefficient of friction than the second layer 11, the conveyance of the bonding sheet 50 or the like becomes smooth and favorable. It can be disconnected. The conveyance of the bonding sheet 50 and the like does not cause wrinkles, and the yield is improved.

  In addition, as shown in FIG. 10, in the method of manufacturing the mask 1, the rotating body 38 provided with the cutting blade on the outer peripheral surface of the cylindrical shape, and the receiving stand 39 at the position opposite to sandwich the bonding sheet 50 etc. A cutting device 32 may be used. In the cutting step S <b> 2, one of the first layer 10 and the third layer 12 is in contact with the pedestal 39, the other is opposed to the rotary body 38, and the rotary body 38 rotates while pressing in the direction of the pedestal 39. You may cut | disconnect, conveying junction sheet 50 grade | etc.,.

  In this case, since the bonding sheet 50 or the like is cut while being transported, the number of manufacturing steps can be reduced. In addition, since the first layer 10 or the third layer 12 is in contact with the pedestal 39, the rotating sheet 38 can be smoothly conveyed by rotating while being pressed in the direction of the pedestal 39.

  Further, as shown in FIGS. 9 and 12, the method of manufacturing the mask 1 may include a wire disposing step S3 and a bent portion forming step S4. The wire disposing step S3 is a step of disposing the wire 80 on the bonding sheet 50 or the like. Bent part formation process S4 bends a part of joining sheet 50 grade so that wire 80 arranged by wire arrangement process S3 may be covered, and it forms bending part 5 which covers wire 80, and makes bending part 5 It is a step of bonding to the three layers 12. In this case, in addition to the mask manufacturing method, the mask 1 in which the wire 80 is disposed can be manufactured. The mask 1 and its manufacturing method described above are an example.

  In addition, this invention is not limited to said embodiment, A various change is possible. For example, FIG. 1 shows the case where the mask main body 2 has substantially the same widthwise dimension at the ear hook portion 3 and the central position C in the longitudinal direction, but the present invention is not limited thereto. The widthwise dimension of the ear hooking portion 3 may be larger than the widthwise dimension of the central position C in the longitudinal direction. Also, conversely, the widthwise dimension of the central position C in the longitudinal direction may be larger than the widthwise dimension of the hook portion 3. It is possible to change the dimensions in consideration of the use scene of the mask and the design.

  Although the mask 1 showed the example which is object shape with respect to the center position C of a longitudinal direction, it does not restrict to this. For example, the mask 1 may have an asymmetric shape with respect to the central position C in the longitudinal direction.

  Although at least one of the first layer 10 and the third layer 12 shows an example in which the material has a smaller coefficient of friction than the second layer 11, the present invention is not limited thereto. The second layer 11 may have a coefficient of friction equivalent to that of the first layer 10 or the third layer 12, and furthermore, the coefficient of friction of the first layer 10 or the third layer 12 is the coefficient of friction of the second layer 11. The above may be sufficient. Even in such a case, it is possible to give different functions to the first layer 10 or the third layer 12 and the second layer 11.

  The mask 1 showed the example formed by cutting process S2 which cut | disconnects the joining sheet 50 which the 1st layer 10, the 2nd layer 11, and the 3rd layer 12 joined, the joining sheet 500, and the joining sheet 600 in the same process. But it is not limited to this. The mask 1 may be formed by separately cutting at least one of the first layer 10, the second layer 11, and the third layer 12 and then bonding them.

  Although both the mask 1B and the mask 1C showed the example joined to the mask main-body part 2 using the member which covers the wire 80, it does not restrict to this. For example, the wire 80 may be directly bonded to the third layer 12. As an example of the bonding method, the wire 80 and the third layer 12 may be bonded, or the wire 80 may be welded to the third layer 12. Furthermore, the wire 80 may be bonded to the first layer 10.

  Although the mask 1D shown in FIG. 8 includes the protrusions 20 and the protrusions 21, only one of them may be used. The mask 1D may include only the protrusion 20 in order to cover the nose reliably, or may include only the protrusion 21 so as to cover a portion of the jaw.

  Although the mask 1 except the mask 1F showed the example which joins the 1st layer 10, the 2nd layer 11, and the 3rd layer 12 in the whole surface, it is not restricted to this. For example, the mask main body 2 can also join only the outer peripheral portion in a spot manner. Also, for example, the mask body 2 can be partially joined to the inside in addition to the outer peripheral portion.

  In the mask 1F, the first layer 10 and the second layer 11, or the second layer 11 and the third layer 12 partially have a non-bonding region 61 which is not bonded to each other, and the non-bonding region 61 is a fourth layer Although the example which is an area | region which includes all 60 and is wider than the 4th layer 60 was shown, it does not restrict to this. For example, a part of the fourth layer 60 may be joined to the first layer 10 or the second layer 11 or the second layer 11 or the third layer 12. In this case, the mask 1 can be more stretchable than when the entire surface of the fourth layer 60 is joined to the first layer 10 and the second layer 11 or the second layer 11 and the third layer 12.

  Although the 4th layer 60 showed the example which has a filter raw material, it is not restricted to this. For example, the fourth layer 60 may be made of a material impregnated with a fragrance. By wearing the mask, the user can obtain a relaxing effect. Also, instead of impregnating the third layer 12 with the moisturizer 14, the fourth layer 60 may be impregnated with the moisturizer 14.

  Although the mask 1C showed the example containing the moisturizer 14 or the antibacterial agent 16 in the range of the predetermined | prescribed range 73, it does not restrict to this. For example, the entire mask 1 may contain the moisturizing agent 14 or the antibacterial agent 16, or the moisturizing agent 14 or the antibacterial agent 16 may be included in the area other than the area across the central position C in the longitudinal direction. Alternatively, the mask 1 may include the moisturizer 14 or the antibacterial agent 16 in the first layer 10 or the second layer 11 as well as the third layer 12.

  Although the 1st layer 10 or the 3rd layer 12 of the mask 1 showed the example which has the raw material of the fabric or the cloth of a knitted fabric, or the 1st nonwoven fabric 91, it is not restricted to this. It is also possible to select other materials that have stretchability and can be processed such as printing and dyeing.

  Although the 2nd layer 11 of the mask 1 showed the example which has a raw material of a foamed article or the 2nd nonwoven fabric 92, it is not restricted to this. It is also possible to select other materials having elasticity and elasticity.

  The mask manufacturing method for manufacturing the mask 1 forms the mask main body 2 by cutting the first layer 10 such as the bonding sheet 50, the second layer 11, and the third layer 12 in the same process using the cutting device 32. Although the example provided with the cutting process S2 which performed is shown, it does not restrict to this. At least one layer of the first layer 10, the second layer 11, or the third layer 12 in the bonding sheet 50 or the like may be cut in another step.
