Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In each drawing, unless otherwise specified, the same or corresponding configurations may be designated by the same reference numerals and description thereof may be omitted. In addition, the drawings are schematic to help the understanding of the invention.

(Basic mask configuration)
The mask according to one embodiment of the present invention may be a mask capable of covering the wearer's face, more specifically, at least the wearer's nose and mouth. The mask according to this embodiment may have a function of preventing foreign matter from reaching the face and preventing droplets generated from the wearer from scattering, and is also called a sanitary mask or a surgical mask. .. The mask may be disposable or reusable by washing.

FIG. 1 shows a plan view of the mask 100 according to this embodiment. FIG. 1 is a view of the mask 100 as viewed from the outside, that is, from the side where the mask 100 is exposed to the outside without facing the face when worn. Further, FIG. 2 shows a plan view of the mask as viewed from the inside (face side).

As shown in FIG. 1, the mask 100 according to the present embodiment is arranged in front of the wearer's face at the time of wearing, and has a mask body (also referred to simply as a body) 10 which can mainly cover the wearer's nose and mouth and a mask. It includes a pair of

ear materials

20 and 20 coupled to the main body 10. The mask body 10 has a vertical direction D1 corresponding to the vertical direction of the wearer's face at the time of wearing, and a horizontal direction D2 orthogonal to the vertical direction D1. In the form of FIG. 1, the mask body 10 has a rectangular plan view shape having a long side in the lateral direction D2, but the plan view shape of the mask body 10 is not limited to that shown in the drawing.

As shown in FIGS. 1 and 2, the mask body 10 has a pleated structure 15 formed by a plurality of folds arranged side by side in the vertical direction D1. The folds of the pleated structure 15 are formed by folding the sheet constituting the main body 10 along a folding line along the lateral direction D2. Then, in a state where a plurality of folds are formed, the side portions (lateral D2 end portions) of the mask main body 10 are joined and fixed. Therefore, when the mask 100 is used, the folds of the pleated structure 15 are widened in the vertical direction D1 so that the center of the horizontal direction D2 is curved so as to protrude toward the outer surface side of the mask 100 so as to match the three-dimensional shape of the face. Can be transformed into a different shape. The specific configuration of the pleated structure 15 is not particularly limited, and may be a known configuration formed on the mask body.

As shown in FIGS. 1 and 2, the pair of

ear materials

20 and 20 are arranged on the outer surface of the main body 10. As shown in FIG. 1, each ear material 20 may have an annular shape or a plan view shape including the annulus. At the time of wearing, the ear material 20 can be hung on the ear so that the wearer's ear enters the inside of the ring of the ear material 20, that is, the opening 29 in the center of the ear material 20.

As shown in FIG. 1, the contour of the ring of the ear material 20 may have a wavy shape or may have irregularities. Further, the wave shape may be provided on at least one of the inner contour and the outer contour of the ring, but it is preferable that the wave shape is provided on at least the inner contour. The entire contour of the ring of the ear material 20 does not have to be provided with a wavy shape. For example, the portion where the ear material 20 comes into contact with the ear when the mask 100 is worn, that is, the lateral direction D2 of the mask 100 before the start of use. It is preferable that it is formed in a portion located near the center. In particular, since the inner contour of the portion that comes into contact with the ear when worn is provided with a wave shape, the convex portion included in the wave shape can easily move independently, so that the ear material 20 can easily fit the shape of the ear. Therefore, the ear material 20 can be stably arranged on the back side of the ear when the mask 100 is worn.

The pair of

ear materials

20 and 20 may be configured as continuous sheets that are separably connected to each other at the center of D2 in the lateral direction. The bonding form of the separable bonding portions 28 of the pair of

ear materials

20 and 20 is not particularly limited, but it is preferable that the bonding is separable by pulling with the normal force of the user. For example, it may be formed as a perforation as shown in FIG. Further, the joint portion 28 may be formed by reducing the thickness of the sheet or by using other means to weaken the boundary between the pair of

ear materials

20 and 20 or make it easy to apply stress. Further, the pair of

ear materials

20 and 20 may be formed independently, slightly overlapped at the center of D2 in the lateral direction, and separably bonded by an adhesive, a heat seal, or the like to form a bonded portion 28. good.

The mask body 10 may have a multilayer structure in which a plurality of layers are laminated. For example, the structure may include at least three layers in which an intermediate layer having an enhanced function of collecting foreign substances (dust, pollen, bacteria, viruses, etc.) is sandwiched between an outer layer and an inner layer. Each layer constituting the main body 10 may include a fiber-containing layer such as a non-woven fabric, a woven fabric, or a knitted fabric, and preferably includes a non-woven fabric. Examples of the non-woven fabric include spunbonded non-woven fabric, spunlaced non-woven fabric, meltblown non-woven fabric, air-through non-woven fabric, point-bonded non-woven fabric and the like. Further, it is preferable to use a meltblown nonwoven fabric containing fine fibers as the intermediate layer. The fiber constituting the fiber-containing layer is preferably a resin fiber, and examples of the resin type of the resin fiber include polyethylene, polypropylene, polyethylene terephthalate, and nylon. The basis weight of the outer layer and the inner layer may be 10 to 50 g / m ² , preferably 15 to 50 g / m ² . Basis weight of the foreign matter trapping highly intermediate layer, preferable to be 10 ~ 100g / ^{m 2,} and more preferably a 15 ~ 50g / ^{m 2.}

The ear material 20 may be formed of a material having elasticity, preferably a material having higher elasticity than the main body 10. Further, the ear material 20 may have elasticity at least in the lateral direction D2, and may have elasticity in both the vertical direction D1 and the lateral direction D2. The elasticity in the vertical direction D1 and the elasticity in the horizontal direction D2 may be the same or different from each other. When the elasticity in the vertical direction D1 and the elasticity in the horizontal direction D2 are different, it is preferable that the elasticity in the horizontal direction D2 is higher than the elasticity in the horizontal direction D2 of the main body 10. The ear material 20 is hung on the wearer's ear at the time of wearing and is pulled mainly in the lateral direction D2. Therefore, by having elasticity at least in the lateral direction D2, the main body 10 can be better positioned and fixed to the front of the face, and the burden on the ears of the ear material 20 can be reduced.

The ear material 20 may include a fiber-containing sheet having elasticity and / or may include a film having elasticity or elasticity. Examples of the fiber-containing sheet include non-woven fabrics, woven fabrics, knitted fabrics, and the like, and among these, it is preferable to use non-woven fabrics because of their good touch and breathability. Examples of the non-woven fabric include air-through non-woven fabric, spunbond non-woven fabric, spunlace non-woven fabric, needle punch non-woven fabric, chemical bond non-woven fabric and the like. The fiber contained in the nonwoven fabric is preferably a resin fiber, and examples of the resin type of the resin fiber include polyethylene, polypropylene, polyethylene terephthalate, and nylon.

The ear material 20 may include the above-mentioned elastic fiber-containing sheet or elastic film in a single layer, or a plurality of the above-mentioned elastic fiber-containing sheets and / or elastic films are laminated. For example, it may be configured by laminating a fiber-containing sheet and an elastic film. When the fiber-containing sheet has elasticity, the elasticity is expressed by the fiber-containing sheet containing elastic fibers, for example, the fiber material itself has elasticity or the fibers are crimped fibers. It's okay. Alternatively, elasticity may be exhibited by a predetermined physical structure, for example, by having irregularities on the surface. Further, the ear material 20 may be formed by sandwiching the thread-like rubber with a fiber-containing sheet having or not having elasticity. When the elasticity of the fiber-containing sheet is low or not, the fiber-containing sheet can be attached from both sides in a stretched state.

More specifically, as the ear material 20, a single-layer non-woven fabric such as a stretchable air-through non-woven fabric, a stretchable spunbond non-woven fabric, a stretchable spunlace non-woven fabric, a stretchable needle punch non-woven fabric, and a stretchable chemical bond non-woven fabric can be used. .. Further, a non-woven fabric having a plurality of layers such as spunbond / meltblown / spunbond can be used. Further, a laminated sheet such as a non-woven fabric / stretchable film, a non-woven fabric / stretchable film / non-woven fabric (for example, spunbond / stretchable film / spunbond, air-through / stretchable film / air-through, etc.) can be used. When the ear material 20 is formed from a plurality of layers, the layers may be bonded to each other with a stretchable or non-stretchable hot melt non-woven fabric (a non-woven fabric in which the fibers are softened or melted by heating and can be adhered to other members). The basis weight of the ear material 20 may be ^{20 to 150 g / m 2.} The thickness of the ear material 20 may be 100 to 3,000 μm.

The pair of

ear materials

20 and 20 are connected to the side portions (lateral D2 end portions) of the outer surface of the main body 10, respectively. More specifically, the pair of

ear materials

20 and 20 are bonded to both sides of the main body 10 via the

auxiliary materials

30 and 30, respectively (the auxiliary materials will be described in detail later). That is, the outer portions of the pair of

ear materials

20 and 20 in the lateral direction D2 are joined to the main body 10, and the other parts are not joined to the main body 10. When starting to use the mask 100 according to this embodiment, before wearing the mask 100, the pair of

ear materials

20 and 20 are separated from each other by releasing the separable bonds (separation operation). The portions of the

ear materials

20 and 20 that are not joined to the main body 10 are opened laterally to the D2 side (also referred to as unfolding operation). Such a separation / deployment operation and a configuration related to the operation will be described in more detail below.

(Separation / deployment operation of ear material)
FIG. 3 shows a diagram showing a state in which the mask 100 shown in FIG. 1 is about to be used. Further, FIG. 4 shows a sectional view taken along line II of FIG. At the start of use, the user can pinch or grasp the pair of

ear materials

20 and 20 with their respective hands and pull them in opposite directions as shown in FIG. Thereby, first, the bond of the separable connecting portion 28 can be released. If the joint portion 28 is composed of perforations formed along the boundary line between the pair of

ear materials

20 and 20, the perforations are broken and both

ear materials

20 and 20 are placed along the boundary line. Can be separated. After that, the user can open the pair of

ear materials

20 and 20 outward in the lateral direction D2 in the directions shown by the arrows in FIGS. 3 and 4, while holding the pair of

ear materials

20 and 20, respectively.

FIG. 5 shows a state in which the pair of

ear materials

20 and 20 are opened outward from the lateral D2 from the state of FIG. Further, FIG. 6 shows a sectional view taken along line II-II of FIG. As shown in FIGS. 5 and 6, when the pair of

ear materials

20 and 20 are opened, the

ear materials

20 and 20 are turned inside out, and the surface facing the main body 10 in the state before the start of use is exposed. Then, it is mainly arranged outside the lateral D2 of the main body 10, and the entire outer surface of the main body 10 is exposed.

As shown in FIG. 3, after the user grasps the pair of

ear materials

20 and 20 and opens them outward in the lateral direction D2, the outer surface of the mask 100 becomes the user who opens the

ear materials

20 and 20. Facing each other, the inner surface (face side) of the mask 100 faces the side opposite to the user. Therefore, the mask 100 according to this embodiment is suitable for being worn by another wearer. For example, with the mask 100 placed with the outside of the mask 100 facing up (the outer surface of the main body 10 facing up), the user grips the pair of

ear materials

20 and 20 by hand and outside the lateral D2. Open towards. After that, while holding the pair of

ear materials

20 and 20, the mask 100 is moved to the face of another wearer, and the mask body 10 is placed at a desired position on the face of the wearer, and then the holding method is changed. Instead, the pair of

ear materials

20 and 20 can be hung on the wearer's ears, respectively. Therefore, the mask 100 according to this embodiment can be suitably used when a person who has difficulty in wearing the mask by himself / herself, such as a child or a sick person, is to wear the mask.

Further, since the pair of

ear materials

20 and 20 are arranged on the outer surface of the main body 10 as described above, when the pair of

ear materials

20 and 20 are separated from each other and opened outward in the lateral direction D2, the user The possibility of the hand touching the inside of the mask 100 can be reduced or eliminated. Therefore, the unfolding operation of the

ear materials

20 and 20 in the preparatory stage before wearing the mask 100 can be performed hygienically.

Further, as shown in FIG. 3, the pair of

ear materials

20 and 20 has a pinch portion that can be picked by the user when the pair of

ear materials

20 and 20 are separated from each other and opened outward in the lateral direction D2. It may have 25, 25. It is preferable that the

knob portions

25, 25 project from the edge of the main body 10 in a plan view. Since the

grips

25 and 25 protrude from the edge of the main body 10, the user picks the

picks

25 and 25 with both hands without touching the main body 10 itself, that is, neither the outer surface nor the inner surface of the main body 10. Can be pinch. Then, the user can separate and deploy the pair of

ear materials

20 and 20 without touching or hardly touching the main body 10. Therefore, even in a situation where the user cannot give sufficient consideration to the hygiene of the fingers, the mask 100 in a good hygiene state can be worn by oneself or another person. Further, it is preferable that the

knob portions

25, 25 project from the lower end (lower end portion in FIG. 3) of the main body 10 in a plan view because the ear material can be naturally separated and deployed.

Further, since the ear material 20 has the

knob portions

25 and 25, the user can easily adjust the ear material by holding the

grip portions

25 and 2 when or after the ear material 20 is hung on the wearer's ear. Can be done. That is, holding the

knobs

25 and 25, the ear material 20 is displaced relative to the ear in the circumferential direction to adjust the position, and the ear material 20 is pulled or loosened toward the rear side. The tension of the ear material 20 can be adjusted.

The maximum length of the vertical D1 of the protruding portion of the grip portion 25 from the lower end of the main body 10, that is, the vertical D1 length from the lower end of the main body 10 to the apex of the protruding portion of the grip portion 25 is 5 to. It may be 15 mm. Further, the length of the lateral D2 from the end of the lateral D2 of the mask 100 or the main body 10 to the position of the apex of the protruding portion of the knob 25 closer to the end is the length of the entire mask 100 or the main body 10. It may be 45 to 90% of 1/2 the length of the lateral D2.

While the mask 100 is being worn, that is, when the

ear materials

20 and 20 are opened sideways and hung on the ears, the

ear materials

20 and 20 are pulled toward the wearer's ears, and the ear materials 20 are accompanied by this. The joint portion of 20 with the main body 10 is pressed toward the wearer's face. Here, in this embodiment, the pair of

ear materials

20 and 20 are connected to both sides of the outer surface of the main body 10, respectively (FIGS. 3 and 4). Therefore, while the mask 100 is worn, a part of the ear material 20 is arranged on the outside of both sides of the main body 10 (FIGS. 5 and 6), that is, both sides of the main body 10 are the ear material 20 and the wearer's face. Since it is arranged between and, both side portions of the main body 10 are pressed toward the face by the ear material 20. As a result, the gap between the main body 10 and the face can be reduced on both sides of the mask main body 10, and the function of the mask, for example, the function of blocking foreign matter, the function of not scattering the droplets emitted by the wearer, and the like can be improved. Further, since the ear material 20 is not arranged on the inside (face side) of both side portions of the main body, the ear material 20 does not come into contact with the wearer's face on both side portions of the main body 10 during wearing, which is better. You can also get a feeling of wearing.

Note that a mark 18 that enables distinction between the outer surface and the inner surface of the main body 10 (distinguishing the front and back) may be formed on the outer surface and / or the inner surface of the main body 10 by embossing, printing, sewing, or the like. The form of the mark 18 is not limited as long as it can be visually recognized by the user. As shown in FIG. 1, the mark 18 may be a character, a number, a symbol, a figure, a logo, or the like.

(Auxiliary material)
In this embodiment, as described above, the pair of

ear materials

20 and 20 are connected to both sides of the main body 10 via the

auxiliary materials

30 and 30, respectively. The configurations and functions of the

auxiliary materials

30 and 30 will be described in more detail below.

FIG. 7 shows an enlarged view of a portion of the mask 100 where the auxiliary material 30 is provided. 7 (a) is a partial plan view, and FIG. 7 (b) is a sectional view taken along line III-III of FIG. 7 (a). Further, FIG. 8 shows a view after the ear material 20 is opened laterally D2 outward from the state shown in FIG. 7. 8 (a) is a partial plan view, and FIG. 8 (b) is a sectional view taken along line IV-IV of FIG. 8 (a). In the examples of FIGS. 7 and 8, the main body 10, the ear material 20, and the auxiliary material 30 are laminated in this order. In FIGS. 7 and 8, the pleated structure 15 (FIG. 1) of the mask body 10 is not shown.

The auxiliary material 30 is provided to indirectly connect the main body 10 and the ear material 20 with the main body 10 and the ear material 20 interposed therebetween. More specifically, the main body 10 and the auxiliary material 30 are joined at the first joint portion B1, the ear material 20 and the auxiliary material 30 are joined at the second joint portion B2, and the main body 10 and the ear material 20 are joined. Is not directly joined to. The first joint portion B1 and the second joint portion B2 are, for example, means for joining the facing surfaces of the members by applying pressure and / or heat, for example, heat sealing, ultrasonic sealing, non-heating embossing, etc. Can be formed by. Of these, it is preferable to use a heat seal because reliable bonding is possible.

As described above, the main body 10 has a function of blocking the intrusion of foreign matter and preventing the scattering of droplets generated by the wearer, while the ear material 20 is hung on the wearer's ear at the time of wearing. It has a function of holding the main body 10. Therefore, the main body 10 and the ear material 20 are usually made of different materials, and it is preferable that the ear material 20 is made of a material having relatively high elasticity. Therefore, in the conventional configuration in which the main body 10 and the ear material 20 are directly joined, when a force is applied to the mask 100 due to the ear material 20 being pulled or the like, the main body 10 cannot follow the elongation of the ear material 20. There is also the possibility that the joint cannot be maintained and the two will come off from each other.

On the other hand, according to this embodiment, the first joint portion B1 which is the joint portion between the main body 10 and the auxiliary material 30 and the second joint portion B2 which is the joint portion between the ear material 20 and the auxiliary material 30 are separately separated. Can be formed. That is, when the joint portion includes the first joint portion B1 and the second joint portion B2, the force applied to the joint portion is dispersed, and the ear material 20 is less likely to come off. In addition, each joint can be formed in a form suitable for the characteristics of the two members to be directly bonded. Further, as the material of the auxiliary material 30, it is possible to select a material that can optimize both the bonding with the main body 10 and the bonding with the ear material 20. As a result, the indirect bond between the main body 10 and the ear material 20 is less likely to break, and as a result, a mask that is less likely to break even when a force is applied can be obtained.

As described above, before wearing the mask 100 of this embodiment, the

ear materials

20 and 20 are separated from each other by picking and pulling the

grip portions

25 and 25 provided on the pair of

ear materials

20 and 20, respectively. , Open to each side. In such a separation / deployment operation of the

ear materials

20 and 20, the mask 100 may be used depending on the configuration of the joint portion 28 of the pair of

ear materials

20 and 20 and the method of separating the

ear materials

20 and 20 of the user. May cause damage. For example, when it is difficult to start the separation of the

ear materials

20 and 20 at the joint portion 28, the user pulls the

ear materials

20 and 20 open by excessive force, and the joint portion between the ear material 20 and the main body 10 is opened. There is a possibility that the ear material 20 will come off due to a large force applied to the ear material 20. However, according to this embodiment, the

ear materials

20 and 20 are not easily peeled off from the main body 10 even in the separation / deployment operation of the

ear materials

20 and 20 at the start of use, and the wearing can be started in a good state.

Further, according to this embodiment, it is not necessary to use a large amount of adhesive or an adhesive that becomes excessively hard after curing in order to firmly bond the main body 10 and the ear material 20, so that each member does not need to be used. The function of the mask is not hindered, the flexibility of the mask can be maintained, and a mask with good wearing feeling and usability can be obtained.

The auxiliary material 30 may be formed of a non-stretchable or small material, or is preferably formed of a material having a certain degree of elasticity. Further, the auxiliary material 30 may be formed of a material whose shape can be irreversibly changed when a force is applied. The auxiliary material 30 may also contain the same type of stretchable nonwoven fabric as the ear material 20, but the stretchability of the auxiliary material 30 is preferably at least lateral D2 and smaller than the stretchability of the ear material 20. .. Further, the elasticity of the auxiliary material 30 is preferably larger than the elasticity of the main body 10 at least in the lateral direction D2.

By providing the auxiliary material 30 having elasticity, even when the ear material 20 is pulled, the difference between the elongation of the main body 10 and the elongation of the auxiliary material 30, and the elongation of the ear material 20 and the elongation of the auxiliary material 30 The difference can be suppressed respectively. The auxiliary material 30 can act as a cushioning material between the main body 10 and the ear material 20. Therefore, both the first joint portion B1 between the main body 10 and the auxiliary material 30 and the second joint portion B2 between the ear material 20 and the auxiliary material 30 are less likely to break, and as a result, the indirect connection between the main body 10 and the ear material 20 Bonds are less likely to break. The basis weight of the auxiliary material 30 may be ^{5 to 100 g / m 2.} The thickness of the auxiliary material 30 may be 100 to 1,000 μm.

As shown in FIG. 7A, the auxiliary material 30 may be a sheet-like member extending along the vertical direction D1 of the mask 100. The length of the auxiliary material 30 in the vertical direction D1 is preferably the same as the length of the vertical direction D1 of the mask 100 (the length of the vertical direction D1 of the main body 10), but is shorter than the length of the vertical direction D1 of the mask 100. You may. Further, on one side (either left or right side) of the lateral direction D2 of the mask 100, the outer end 31 of the lateral direction D2 of the auxiliary material 30 is inward of the lateral direction D2 from the outer end 11 of the lateral direction D2 of the main body 10. It may be located on the outside or on the outside, but as shown in FIG. 7A, it is preferably located at a position aligned with the outer end 11 of the main body 10 in the lateral direction D2.

The length (width) W of the auxiliary material 30 in the lateral direction D2 is preferably 15 to 35 mm, although it depends on the size and configuration of the entire mask 100 and the size, shape, and material of the main body 10 and the ear material 20. By setting the length of the lateral direction D2 within the above range, it is possible to sufficiently secure the areas of the first joint portion B1 and the second joint portion B2, respectively, while the auxiliary material 30 is used for the separation / deployment operation at the start of use and / Alternatively, it does not interfere with the wearing and does not interfere with the functions of the main body 10 and the ear material 20.

The width W of the auxiliary material 30 can be set to a width such that the auxiliary material 30 overlaps with the opening 29 of the ear material 20 as shown in FIG. 7 and the like. However, the width W of the auxiliary material 30 may be set so that the auxiliary material 30 does not overlap with the opening 29 of the ear material 20.

As shown in FIGS. 7A and 7B, the auxiliary material 30 is arranged on the outer surface side of the main body 10. Therefore, even while the mask 100 is being worn, the possibility that the auxiliary material 30 itself comes into contact with the wearer's face is low, and the good wearing feeling of the mask 100 of the present embodiment is not hindered.

Further, as described above, the ear material 20 in the present embodiment can function to press both sides of the main body 10 toward the wearer's face, but at least the auxiliary material 30 laminated on the outer surface side of the main body 10 is also included. Partially, together with the ear material 20, it can perform the function of pressing the main body 10 toward the face. As a result, the gap between both sides of the main body 10 and the face can be further reduced, and the function of the mask 100 can be improved.

In the state before the start of use of the mask 100, as shown in FIGS. 7A and 7B, the first joint portion B1 which is the joint portion between the main body 10 and the auxiliary material 30 is the ear material 20 and the auxiliary material 30. It is located on the outer side of D2 in the lateral direction from the second joint portion B2 which is the joint portion with and. Therefore, when the ear material 20 is opened outward in the lateral direction D2 at the start of use, a part of the auxiliary material 30 (outside the lateral D2) remains fixed to the main body 10 due to the presence of the first joint portion B1. The inside of the auxiliary material in the lateral direction D2 is opened outward (sideways) in the lateral direction D2 together with the ear material 20 by the second joint portion B2 (FIGS. 8A and 8B). That is, the auxiliary material 30 is bent in the horizontal direction D2 along a line along the vertical direction D1.

Restoring force (force to return from the bent state to the state before bending) is generated in the bent auxiliary material 30 according to the characteristics of the materials constituting the auxiliary material 30. As described above, during wearing, the ear material 20 and at least a part of the auxiliary material 30 act to press both sides of the main body 10 toward the face, and such an action of pressing both sides of the main body 10. Can be improved by bending the auxiliary material 30. As shown in FIGS. 7 and 8, in the example in which the auxiliary material 30 is arranged on the outer surface side of the ear material 20 and is arranged on the outermost surface of the mask 100, the ear material 20 is opened laterally to the outside of D2. In this state, since the auxiliary material 30 is arranged inside the ear material 20 (face side), the function of pressing both side portions of the main body 10 toward the face is further enhanced. Therefore, the action of reducing the gap between the mask body and the face is further improved.

In a form in which the auxiliary material 30 is bent when the ear material 20 is deployed, the auxiliary material 30 preferably has a relatively high bending resilience (strength of the repulsive force when bent), for example. It may have a bending resilience larger than the bending resilience of the ear material 20. As a result, the restoring force of the bent auxiliary material 30 is enhanced, and the action of the auxiliary material 30 pushing the main body 10 toward the inside (face side) can be further improved.

In the state before the start of use (FIGS. 7A and 7B), on one side (either left or right side) of the lateral D2 of the mask 100, the outer end 21 of the lateral D2 of the ear material 20 is. It is located inward of the lateral D2 from the outer end 11 of the lateral D2 of the main body 10. That is, the ear material 20 is laterally displaced inward of D2 with respect to the main body 10. Therefore, by laminating the main body 10, the ear material 20, and the auxiliary material 30 in order, the portion where the auxiliary material 30 can directly contact the main body 10 and the auxiliary material 30 are the ear material 20 without performing a process such as folding back. A portion that can be directly contacted can be easily formed. Therefore, the first joint portion B1 between the main body 10 and the auxiliary material 30 and the second joint portion B2 between the ear material 20 and the auxiliary material 30 can be formed without a complicated structure and process. For example, the auxiliary material 30 is arranged on the ear material 20 so that the outer end 21 of the lateral direction D2 of the ear material 20 is located inward of the lateral direction D2 from the outer end 31 of the lateral direction D2 of the auxiliary material 30. A combination obtained by joining the ear material 20 and the auxiliary material 30 at the second joint portion B2 is prepared. Then, the combination is arranged on the main body 10 so that the outer end 21 of the lateral direction D2 of the ear material 20 is located inward of the lateral direction D2 from the outer end 11 of the lateral direction D2 of the main body 10. As a result, a portion where the vicinity of the outer end 11 of the lateral direction D2 of the main body 10 and the auxiliary material 30 are in direct contact with each other can be obtained, so that the first joint portion B1 can be formed in a state where the combination and the main body 10 are overlapped with each other. ..

The first joint portion B1 is preferably formed over the vertical direction D1. _{The length (width) w 1} (FIG. 7 (a)) of the first joint portion B1 in the lateral direction D2 can be 3 to 10 mm. In the example shown in FIG. 7, the width w ₁ of the first joint portion B1 is constant over the vertical direction D1, but the width w ₁ does not necessarily have to be constant and may vary depending on the location. By setting the width w ₁ in the above range, a reliable joint can be formed between the main body 10 and the auxiliary material 30, and it is possible to prevent the first joint portion B1 from becoming hard and impairing the flexibility of the entire mask 100. .. In addition, it is possible to reduce the discomfort that occurs when the first joint portion B1 touches the face.

It is preferable that the second joint portion B2 is also formed over the vertical direction D1. _{The length (width) w 2} (FIG. 7 (a)) of the second joint portion B2 in the lateral direction D2 can be 3 to 10 mm. In the example shown in FIG. 7, the width w ₂ of the first joint portion B1 is constant over the vertical direction D1, but the width w ₂ does not necessarily have to be constant and may vary depending on the location. By setting the width w ₂ in the above range, a reliable joint can be formed between the ear material 20 and the auxiliary material 30, and the second joint portion B2 becomes hard, which impairs the flexibility of the entire mask 100. Can be prevented.

It is preferable that the first joint portion B1 and the second joint portion B2 are provided apart from each other. _{The distance w 0} (FIG. 7A) between the first joint portion B1 and the second joint portion B2 may be 3 to 13 mm. Further, the distance w ₀ is preferably larger than _{the width w 1} of the first joint portion B1. By setting the distance w ₀ to the above value, when the ear material 20 is unfolded, the ear material 20 can be easily turned inside out and the auxiliary material 30 can be bent, and the flexibility of both sides of the mask 100 can be prevented from being impaired. can.

When the ear material 20 is deployed, the ear material 20 and the auxiliary material 30 are turned over and the auxiliary material 30 is bent with the vicinity of the inner end of the lateral direction D2 of the first joint portion B1 as a base point. Therefore, it is preferable that the distance s between the inner end of the first joint portion B1 in the lateral direction D2 and the outer end 21 of the ear material 20 in the lateral direction D2 is secured to some extent. Further, by not increasing the distance s excessively, it is possible to avoid shortening the lateral D2 length of the ear material 20. The distance s may be 1 to 10 mm.

When the first joint portion B1 and the second joint portion B2 are formed by a heat seal, the welded portion formed by the heat seal may be continuous in the vertical direction D1 and / or the horizontal direction D2, or may not be continuous. It may be continuous. If it is discontinuous, a plurality of welded portions may be arranged over the entire joint. Since the welded portions are arranged discontinuously, it is possible to form a reliable joint while ensuring a certain degree of flexibility in the joint portion.

9 (a) and 9 (b) show enlarged views of the partial V and the partial VI in FIG. 7 (a), respectively. As shown in FIG. 9A, the first joint portion B1 includes a plurality of welded portions discontinuous in each of the vertical direction D1 and the horizontal direction D2. More specifically, the welded portions of the squares are arranged vertically and horizontally at a predetermined distance from each other. By having the welded portions discontinuous in each of the vertical direction D1 and the horizontal direction D2 of the joint portion, a highly flexible joint portion can be obtained over the entire first joint portion B1 while forming a reliable joint.

On the other hand, as shown in FIG. 9B, the second joint portion B2 includes a plurality of welded portions discontinuous in the vertical direction D1. In the illustrated example, the welded portion included in the second joint portion B2 has a bar shape (or a linear shape) extending in the lateral direction D2, and more specifically, a rectangle. Since the ear material 20 is pulled during wearing, the second joint portion B2 (the ear material 20 and the auxiliary material 30 joined by the second joint portion B2) is particularly susceptible to a force in the lateral direction D2. Therefore, by forming the welded portion included in the second joint portion B2 into a bar shape continuous in the lateral direction D2, it is possible to suitably prevent the ear material 20 from peeling off when pulled in the lateral direction D2. The shape of the welded portion of the joint portion is not limited to the one shown in the figure as long as the joint portion can sufficiently maintain the strength. The welded portion may be formed in a shape narrower than the length, that is, in a linear shape (straight line or curved line), or in a dot shape (shape that can be visually recognized as a point). More specifically, the plan view shape of each welded portion may be any shape such as a quadrangle such as a rectangle or a rhombus, a polygon other than the quadrangle, a circle, or an ellipse.

In the example described above, the auxiliary material 30 interposed for the connection between the main body 10 and the ear material 20 is arranged in one layer on the outermost side of the mask 100, but the arrangement of the auxiliary material 30 is not shown. Not limited to the example of. Further, the auxiliary material 30 may be folded into two layers in a state before the start of use.

FIG. 10 shows one modification of the mask 100 according to this embodiment. FIG. 10 is a diagram corresponding to FIG. 7, and is an enlarged view of a portion of the mask 100 where the auxiliary material 30 is provided. 10 (a) is a partial plan view, and FIG. 10 (b) shows a sectional view taken along line VII-VII of FIG. 10 (a). Further, FIG. 11 shows a view after the ear material 20 is opened laterally D2 outward from the state shown in FIG. 11 (a) is a partial plan view, and FIG. 11 (b) is a sectional view taken along line VIII-VIII of FIG. 11 (a). In the modification shown in FIGS. 10 and 11, the auxiliary material 30 is arranged outside the ear material 20. The other basic configurations are the same as those described with reference to FIGS. 7 and 8, and the same actions and effects can be obtained.

In the examples of FIGS. 10A and 10B, the ear material 20 is arranged on the outermost side when both side portions (both ends of the lateral direction D2) of the mask 100 are viewed from the outside, and the ear material 20 is arranged outside the lateral direction D2 of the ear material 20. The auxiliary material 30 is exposed to the outside from the end 21. Therefore, when the ear material 20 is opened outward in the lateral direction D2 at the start of use and unfolded, the bent auxiliary material 30 is arranged on the outermost side of the main body 10, and the outer end 21 of the ear material 20 is arranged. Covered by auxiliary material 30. Therefore, the outer end 21 of the ear material 20 is not exposed and can be protected during wearing.

Hereinafter, specific embodiments of the present invention will be added.

(Appendix 1)
The embodiment according to Appendix 1 includes a mask body, a pair of ear materials bonded to the mask body, and an auxiliary material arranged on the outer surface side of the mask body, and the pair of ear materials are provided in a state before the start of use. The ear materials are separably coupled to each other and arranged on the outer surface side of the mask body, the contour of the ear material has a wavy shape, and the pair of ear materials are attached to the mask body via the auxiliary material. It is connected to the outer surface of each side.

According to the embodiment according to the above appendix 1, since the pair of ear materials are respectively bonded to the mask body via the auxiliary material, the mask can be configured without directly bonding the ear materials and the mask body. Therefore, the joint portion between the mask main body and the auxiliary material and the joint portion between the ear material and the auxiliary material can be formed separately. That is, each joint can be formed separately in a format suitable for the material of the two members to be directly bonded. As a result, even if the ear material is pulled when the mask is worn, an indirect, hard-to-break bond can be formed between the ear material and the mask body without impairing the function and wearing feeling of the member. A good mask can be obtained.

In this embodiment, the pair of ear materials have a structure in which the pair of ear materials are separably bonded to each other, and at the start of use, the pair of ear materials can be separated from each other and opened laterally. During such a separation / deployment operation, the ear lumber is pulled with an excessively large force depending on the type of connection between the pair of ear lumbers and / or the method by which the user separates the pair of ear lumbers from each other. The mask can be damaged. On the other hand, in this embodiment, the ear material and the mask body are not directly bonded, but are bonded via the auxiliary material as described above, so that the pair of ear materials are separated from each other at the start of use. It is possible to form a mask that is hard to break.

Also, while wearing the mask, that is, when the ear material is opened sideways and hung on the ear, the ear material is pulled toward the wearer's ear, and the ear material is combined with the mask body accordingly. A force is applied to the part so that it is pressed against the wearer's face. In this embodiment, since the pair of ear materials are connected to the outer surface side of the mask body, both side portions of the mask body are arranged inside the ear material (on the face side of the wearer) at the time of wearing. Therefore, both sides of the mask body are pressed toward the face by the ear material. As a result, the gap between the mask body and the face can be reduced on both sides of the mask body, and the function of the mask, for example, the function of blocking foreign matter, the function of not scattering the droplets emitted by the wearer, and the like can be improved. In addition, since the ear material is not arranged on the inside (face side) of both sides of the mask body, the ear material does not come into contact with the wearer's face on both sides of the mask body during wearing, so that the wearing is better. You can get a feeling.

(Appendix 2)
In the aspect according to Appendix 2, the mask has a vertical direction corresponding to the vertical direction of the wearer's face and a horizontal direction orthogonal to the vertical direction, and at least the lateral elasticity of the auxiliary material is increased. It is higher than the lateral elasticity of the mask body and lower than the lateral elasticity of the ear material.

The ear material is a member that can be hung on the wearer's ear during wearing, and is often composed of a material that has higher elasticity than the elasticity of the mask body. Therefore, when the ear material and the mask body are directly bonded, it is difficult for the mask body to follow the expansion and contraction deformation of the ear material, the difference between the elasticity of the ear material and the elasticity of the mask body, and / or the ear during use. Depending on the degree to which the material expands and contracts, the ear material and the mask body may separate. On the other hand, according to the aspect according to the above appendix 2, as the material of the auxiliary material, a material having elasticity between the elasticity of the mask body and the elasticity of the ear material is used at least in the lateral direction. Even when the elasticity of the ear material and the elasticity of the main body are significantly different, the auxiliary material can cushion the difference in elasticity and reduce the possibility that the ear material and the main body are separated from each other.

(Appendix 3)
In the embodiment according to Appendix 3, the main body and the auxiliary material are joined at the first joint portion, and the ear material and the auxiliary material are joined at the second joint portion. The joint portion is located laterally inwardly separated from the first joint portion.

According to the aspect according to the above-mentioned appendix 3, the first joint portion which is the joint portion between the main body and the auxiliary material is in the state before the start of use, that is, in the state where the pair of ear materials are not separated and opened. A second joint portion, which is a joint portion between the ear material and the auxiliary material, is formed laterally outward and laterally inward from the first joint portion. Therefore, when the pair of ear materials are opened laterally (laterally outward) at the start of use, the lateral outer portion of the auxiliary material remains fixed to the main body at the first joint and is lateral to the auxiliary material. Since the inner part in the direction is opened together with the ear material, the auxiliary material is bent laterally. In the bent auxiliary material, a restoring force (force to return from the bent state to the state before bending) is generated according to the characteristics of the material constituting the auxiliary material. Therefore, when the mask is worn, the restoring force of the auxiliary material works from the outer surface side to the inner surface side (face side) of the mask, so that the action of reducing the gap between both sides of the mask body and the face can be enhanced. can.

(Appendix 4)
In the embodiment according to Appendix 4, the auxiliary material is arranged on the outer surface side of the ear material.

According to the aspect according to the above appendix 4, since the auxiliary material is arranged on the outer surface side of the ear material, when the pair of ear materials are opened when the mask is worn, the ear material is arranged on the outermost side and the auxiliary material is arranged. It is placed inside the ear material. Therefore, when the ear material is hung on the ear and pulled, the ear material functions to press the auxiliary material and the mask body toward the face on the side portion of the mask. As a result, the action of reducing the gap between the mask body and the face on both side portions (horizontal end regions) of the mask body is further improved.

(Appendix 5)
In the aspect according to the appendix 5, the lateral outer end of the ear material is located inward from the lateral outer end of the mask body.

According to the aspect according to the above appendix 5, since the positions of the lateral outer end of the ear material and the lateral outer end of the mask body are deviated, the mask body and the ear material are moved from the inner surface side to the outer surface side of the mask. By laminating in order and further laminating the auxiliary material so as to cover both the mask body and the ear material, the auxiliary material can be brought into surface contact with both the mask body and the ear material. Therefore, the auxiliary material and / or the ear material is not bent or folded back, and the joint portion between the mask body and the auxiliary material (first joint portion) and the joint portion between the ear material and the auxiliary material (second joint portion). Part) can be easily formed.

(Appendix 6)
In the embodiment according to Supplementary Note 6, each of the pair of ear materials is provided with a grip portion protruding from the edge of the mask body in a plan view, and the pair of ear materials is pulled by pinching the grip portion at the start of use. Ear materials can be separated from each other.

At the start of use of the mask according to this embodiment, the user can hold the gripped portion with each hand and pull it to separate the bonded ear materials from each other, and further open the ear materials sideways. According to the aspect according to the above-mentioned appendix 6, since the knobs provided on the pair of ear materials are formed so as to protrude from the edge of the mask body, when the user holds the knobs, the user It is possible to reduce the possibility that the finger touches the mask body. Therefore, the user can separate the pair of ear materials and open them sideways while maintaining the hygienic condition of the mask.
