When the air pressure in the internal space of the mask main body increases due to the above, a part of the exhalation is discharged to the outside through the gap of the main body sheet in the non-joined portion.
For this reason, the filling of the expiration in the internal space can be improved, and the decrease in oxygen concentration in the internal space can be improved. Therefore, the health disturbance of the user can be reduced.
Further, when exhaled air is discharged from the non-joining part, fine particles (such as body fluid droplets) in the exhalation are adsorbed on the inner surface of the non-joining part (main body sheet), and the release to the outside is suppressed.
On the other hand, at the time of intake, the main body sheet of the non-joined portion is closed due to a decrease in the atmospheric pressure in the internal space, and the inflow of outside air from this gap is suppressed.
Since the inflow of outside air from the gap is suppressed, most of the outside air introduced into the internal space as intake passes through the main body sheet. Since the fine particles (spray of body fluid, pollen, etc.) in the outside air are captured by the main body sheet, there is no deterioration in the capturing performance.
Therefore, according to the present invention, it is possible to improve the decrease in oxygen concentration caused by the expiration of the expiration in the internal space without reducing the capture performance, and to reduce the health impairment of the user.

FIG. 12 is a configuration diagram showing a modified example of the joint portion 5 of the mask 10.
In the following description, the left side in FIG. 2 may be referred to as the front, and the right side may be referred to as the rear. The front-rear direction of the mask 10 corresponds to the front-rear direction seen from the user when the mask 10 is worn on the face. Further, “upper” and “lower” refer to the upper and lower sides in FIG.

As shown in FIGS. 1 and 2, the mask 10 includes a mask main body 1 and ear hooks 2 provided on both sides of the mask main body 1.
As the mask body 1, a nonwoven fabric using synthetic fibers made of a polyolefin material or a polyester material can be used. Polyolefin materials include polypropylene, polyethylene, poly 1-butene, and the like, and polyester materials include polyethylene terephthalate. As a material of the mask main body 1, a thermoplastic resin can also be used.
The fibers constituting the nonwoven fabric may be single fibers or composite core-sheath fibers. As the composite core-sheath fiber, polyester-polyethylene core-sheath fiber, polypropylene-polyethylene core-sheath fiber, or the like can be used.

The mask main body 1 includes a pair of main body sheets 3 and 3 in which front side edge portions 3a (one side edge portion) (front edge portions) are joined to each other.
As shown in FIG. 2, the main body sheet 3 includes a front side edge 3a that is curved in a substantially arc shape, an upper edge 3d that descends backward, and a substantially linear lower edge 3e that rises backward. And a substantially straight rear side edge 3b (the other side edge) (rear edge). The main body sheet 3 has a shape in which the height dimension is gradually reduced from the front side edge 3a toward the rear.
The front side edge 3a is curved so as to be convex toward the front. For this reason, the mask main body 1 has a three-dimensional shape that is convex forward from the face in an open state so as to be worn on the user's face. The length of the rear side edge 3b (the vertical dimension in FIG. 2) is shorter than that of the front side edge 3a.

As shown in FIGS. 2 to 5, the front side edge portions 3 a and 3 a of the pair of main body sheets 3 and 3 are overlapped along the length direction with the inner surfaces 3 c and 3 c superimposed on one or a plurality of joint portions 5 (one side Side joints).
As shown in FIGS. 2, 4 and 5, the overlapping portion 4 of the front side edge portions 3 a and 3 a is a belt-like region having a substantially constant width over the entire length of the front side edge portion 3 a. This is a region having a constant width from the front edge 3g (one side edge).

As shown in FIGS. 4B and 5, the joint portion 5 is a portion that joins the inner surfaces 3 c and 3 c of the main body sheet 3 to each other.
The plurality of joint portions 5 are formed by being separated in the length direction of the front side edge portion 3a by one or a plurality of non-joint portions 6 (one-side non-joint portion) (intermediate non-joint portion). In the example of illustration, the junction part 5 is a part of the substantially constant width formed intermittently over the full length of the front side edge part 3a. Adjacent joining part 5 and non-joining part 6 are adjacent in the length direction of front side edge part 3a.

When the thermoplastic resin is used as the material of the main body sheet 3, heat welding can be adopted for the bonding between the main body sheets 3 in the bonding portion 5. Moreover, the main body sheets 3 can also be joined with an adhesive such as polyvinyl alcohol.
In the present invention, the sheets can be joined not only by heat welding and adhesive, but also by sewing or any other method.
The joint portion 5 can join a part or the whole width in the width direction of the overlapping portion 4 of the main body sheet 3 to each other. In the illustrated example, the joint portion 5 is formed at a distance from the front edge 3 g of the main body sheet 3.

As shown in FIG. 5 and FIG. 6, the non-joining portion 6 is a portion between the adjacent joining portions 5 and 5 where the main body sheets 3 and 3 are not joined to each other.
In the non-joining part 6, the main body sheets 3 and 3 are overlapped but are not joined to each other.
For this reason, as shown in FIG. 7, the gap 11 between the main body sheets 3 and 3 can be ventilated in the non-joining portion 6, and the gas (exhalation) in the internal space 21 of the mask main body portion 1 is discharged to the outside through this gap 11. can do.
When exhaled air is discharged from the non-joining part 6, fine particles (such as body fluid droplets) in the exhalation are adsorbed on the inner surface of the main body sheet 3 of the non-joining part 6, and the release to the outside is suppressed. Since the non-joining part 6 has a sufficient width, it can effectively adsorb the fine particles in the exhalation and suppress the release to the outside.
As shown in FIG. 11, the non-joining portions 6 may be at regular intervals in the inner and outer directions, or as shown in FIG. 12, the intervals may be gradually narrowed outward (in the direction of the arrow). .
As shown in FIGS. 3, 4, and 6, the front side edge 3 a of the main body sheet 3 protrudes forward when the user 60 is wearing it.

As shown in FIG. 3, the mask main body 1 is preferably formed so as to cover at least a part of the nose 61 of the user 60 and the mouth 62.
A portion in a height range from the upper end to the lower end of the rear side edge 3b of the mask main body 1 is referred to as a main body main portion 1A (see FIGS. 1 and 2). The main body main part 1 </ b> A can cover at least a part of the nose 61 of the user 60 and the mouth 62.
An upper convex portion 1c of the mask main body 1 (a portion higher than the upper end of the rear side edge 3b of the main body sheet 3. That is, a portion protruding upward from the main body main portion 1A) extends from the eye 63a to the nose. It functions as a thermal insulation part that covers the complex shape region 61a (the region that varies depending on the person and undulates complicatedly) over the upper portion of 61. The convex part 1 c also functions as a nose part heat retaining part that covers the upper part of the nose part 61.
In the illustrated example, the upper end 5a of the joint portion 5 is in the convex portion 1c protruding from the main body portion main portion 1A, and is locked to the upper end 61b of the nose portion 61, thereby preventing the mask main body portion 1 from falling off. Held on the face 60a. Further, the upper end 5a of the joint portion 5 is locked to the upper end 61b of the nose portion 61, so that not only the mask main body portion 1 can be prevented from sliding down, but also the mask main body portion 1 can hardly be raised. Reference numeral 1a denotes the upper end of the mask main body 1 (the upper end of the mask main body 1 in a portion excluding the overlapping portion 4). Reference numeral 63 denotes an eye. The upper end 61b of the nose portion 61 is a portion that is the deepest portion of the recess when viewed from the side.

The lower end 1b of the mask main body 1 (the lower end of the mask main body 1 excluding the overlapping portion 4) is formed on the convex portion 1d protruding from the main body main portion 1A so as to reach the jaw 64 of the user 60. can do.

As shown in FIGS. 1 and 2, the ear hooking portion 2 is formed to extend rearward from the rear side edge portion 3 b of the main body sheet 3 of the mask main body portion 1. The ear hook 2 is formed with an ear hook 7 that is hooked on the ear 65 of the user 60. P <b> 1 is an upper side portion of the ear hook 2 and includes an upper portion from the ear hook 7. P <b> 2 is a lower side portion of the ear hook 2, and includes a portion below the ear hook 7.
For the ear hook 2, a sheet such as a nonwoven fabric using synthetic fibers made of a polyolefin material or a polyester material can be used. It is preferable that the ear hook 2 has higher stretchability than the mask main body 1. For example, a nonwoven fabric using elastically stretchable fibers can be used.

The tension of the upper side portion P1 is preferably larger than the tension of the lower side portion P2. Accordingly, the mask main body 1 can be prevented from sliding down, and the mask main body 1 can be stably held at a position where the upper end 5 a of the joint 5 is engaged with the upper end 61 b of the nose 61. Further, by making the tension of the upper side portion P1 larger than the tension of the lower side portion P2, the burden on the ear 65 due to the wearing of the mask 10 can be reduced.
The ear hook 2 may be formed integrally with the mask main body 1 as a part of the mask main body 1.

  As shown in FIGS. 2, 4 and 8, the inner surface 3c of the rear edge 3b of the main body sheet 3 is overlapped with the outer surface 2b of the front edge 2a of the ear hook 2 along the length direction. The main body sheet 3 and the ear hook 2 are joined to each other by a plurality of rear joints 15 in the band-like overlapping portion 8. The overlapping portion 8 of the rear side edge 3b of the main body sheet 3 and the front edge 2a of the ear hook 2 is not limited to the illustrated example, and the outer surface of the main body sheet 3 and the inner surface of the ear hook 2 are overlapped. Also good.

As shown in FIGS. 2 and 4C, the rear joining portion 15 (the other joining portion) is a portion that joins the inner surface 3 c of the main body sheet 3 and the outer surface 2 b of the ear hook 2. The plurality of rear joining portions 15 are formed by being separated in the length direction of the rear side edge portion 3b by one or a plurality of rear non-joining portions 16 (non-joining portions on the other side). In the example of illustration, the back junction part 15 is a part of the substantially constant width formed intermittently along the length direction of the back side edge part 3b.
For welding the main body sheet 3 and the ear hook 2 at the rear joint 15, heat welding or an adhesive can be used.
The rear joint 15 can be joined to each other over the entire width of the overlapping portion 8 between the main body sheet 3 and the ear hook 2, or a part of the overlapping portion 8 in the width direction can be joined to each other.

As shown in FIGS. 5 and 8, the rear non-joining portion 16 is a portion between the adjacent rear joining portions 15 and 15 where the main body sheet 3 and the ear hooking portion 2 are not joined to each other.
In the rear non-joining portion 16, the main body sheet 3 and the ear hooking portion 2 are overlapped but are not joined to each other. For this reason, as shown in FIG. 9, the gap 12 between the main body sheet 3 and the ear hook 2 can be ventilated in the rear non-joining portion 16, and the air in the internal space 21 of the mask main body 1 is externally passed through the gap 12. Can be discharged.
When exhaled air is discharged from the rear non-joining portion 16, fine particles (such as body fluid droplets) in the breath are adsorbed on the inner surface of the rear non-joining portion 16 (main body sheet 3) and the outer surface 2b of the ear hooking portion 2, The release to the is suppressed. Since the rear non-joining portion 16 has a sufficient width, it can effectively adsorb the fine particles in the exhalation and suppress the release to the outside.

  The structure in which the main body sheet 3 and the ear hook 2 are joined to each other by the plurality of rear joints 15 in the overlapping portion 8 is employed only in the overlapping portion 8 of the two ear hooks 2 and the main body sheet 3. Alternatively, both of the two ear hooks 2 may be employed in the overlapping portion 8 with the main body sheet 3.

Hereinafter, a method of using the mask 10 will be described.
As shown in FIG. 3, the mask 10 can be mounted so that the mask body 1 covers at least a part of the nose 61 of the user 60 and the mouth 62.
In the illustrated example, the thermal insulation part 1c (nasal part thermal insulation part) of the mask main body 1 covers a complex shape region 61a (an area that varies depending on the person and undulates complicatedly) extending from the central part 63a to the upper part of the nose 61, and the mask main body. The upper end 5 a of the joint portion 5 of the portion 1 protrudes from the main body main portion 1 A and reaches the upper end 61 b of the nose portion 61. The lower end 1b of the mask main body 1 (the lower end of the front side edge 3a) protrudes from the main body main portion 1A and reaches the jaw 64 of the user 60.

FIG. 13 is a cross-sectional view showing the structure of the human head. In this figure, the cavities existing on the left and right of the median line Y are the nasal cavity M.
On both sides of the nasal cavity M, the ethmoid sinus S ₁ communicating with the nasal cavity M and reaching the vicinity of the eye cavity and the maxillary sinus S ₂ reaching the vicinity of the zygomatic bone are the sinuses.
In the wearing state shown in FIG. 3, since most of the nose 61 is covered by the mask body 1, both the nasal cavity M and the paranasal sinuses (the ethmoid sinus S ₁ and the maxillary sinus S ₂ ) are kept warm. Will be.

As shown in FIG. 7 and FIG. 10, ventilation through the gap 11 of the main body sheet 3 is possible at the non-joining portion 6 of the front side edge 3 a of the main body sheet 3.
For this reason, when the atmospheric pressure in the internal space 21 of the mask main body 1 is increased by the exhalation of the user 60, a part of the exhalation is discharged to the outside through the gap 11 in the non-joining part 6. For this reason, exhalation does not fill the internal space 21, and a decrease in oxygen concentration in the internal space 21 can be improved. Therefore, the health disturbance of the user 60 can be reduced.

  When exhaled air is discharged from the gap 11, the main body sheets 3, 3 are difficult to separate from each other due to a decrease in atmospheric pressure due to the airflow. Since the main body sheet 3 is a structure made of fibers, the inner surface 3c is not a smooth surface, but has irregularities, so that fine particles (such as body fluid droplets) in the exhalation are adsorbed to the inner surface 3c to the outside. Release is suppressed. Since the overlapping portion 4 has a sufficient width, it is possible to effectively adsorb the fine particles in the exhalation and suppress the release to the outside.

As shown in FIG. 9 and FIG. 10, the other part of the breath of the user 60 is the rear non-joining of the overlapping portion 8 between the rear side edge 3 b of the main body sheet 3 and the front edge 2 a of the ear hook 2. It is discharged from the gap 12 in the portion 16 to the outside. For this reason, the fall of the oxygen concentration in the internal space 21 can be improved, and the health disturbance of the user 60 can be reduced.
When exhaled air passes through the gap 12, the main body sheet 3 and the ear hook 2 are difficult to separate due to a decrease in atmospheric pressure due to the air flow, so that some of the fine particles in the exhalation are part of the inner surface 3 c of the main body sheet 3 and the ear hook. 2 is adsorbed on the outer surface 2b. Since the overlapping portion 8 has a sufficient width, it is possible to effectively adsorb fine particles in exhaled air and suppress the release to the outside.

  As shown in FIG. 7, another part of the breath of the user 60 passes through the main body sheet 3 of the mask main body 1 and is discharged to the outside. At this time, some of the fine particles in the exhalation are captured by the main body sheet 3.

As shown in FIG. 6, at the time of intake, the front side edges 3 a, 3 a of the main body sheets 3, 3 of the non-joined portion 6 are closed due to a decrease in the atmospheric pressure of the internal space 21, and the gap 11 leads to the internal space 21. Inflow of outside air is suppressed.
Similarly, as shown in FIG. 8, the main body sheet 3 and the ear hook 2 are also closed at the overlapping portion 8 between the rear side edge 3 b of the main body sheet 3 and the front edge 2 a of the ear hook 2. Inflow of outside air from the gap 12 into the internal space 21 is suppressed.

As shown in FIG. 6 and FIG. 8, since the inflow of outside air from the gaps 11 and 12 is suppressed, most of the outside air introduced into the internal space 21 as intake passes through the main body sheet 3. At this time, fine particles in the outside air (body fluid splashes, pollen, etc.) are captured by the main body sheet 3, so that the capturing performance is not deteriorated.
Therefore, the mask 10 can improve the decrease in oxygen concentration caused by the expiration of the internal space 21 without deteriorating the capture performance, and reduce the health disturbance of the user 60.

The main body sheet used for the mask of the present invention may be composed of one sheet body or a plurality of sheet bodies.
14 and 15 show another example of the main body sheet. FIG. 14 is a cross-sectional view of the joint portion 5 of the front side edge 3a, and FIG. 15 is a cross-sectional view of the non-joint portion 6.
The main body sheet 3 is a laminated structure composed of three sheet bodies 13a. As the sheet 13a, a non-woven fabric using synthetic fibers made of a polyolefin material or a polyester material can be used.
The sheet body 13a can be electretized (electret process).
Electretization is a process of forming a dielectric state in which a predetermined amount of positive or negative charge is applied to the fiber surface and polarized. For the electretization, a known method, for example, a method of charging the sheet body 13a by corona discharge can be adopted.
As shown in FIG. 16, when exhaled air passes through the gap 11 of the non-joining portion 6, the main body sheets 3 and 3 are not easily separated from each other due to a decrease in atmospheric pressure due to the air flow, so that fine particles in exhaled air (such as body fluid splash) Is adsorbed to the inner surface 13c of the sheet body 13a.
When the sheet body 13a is electretized, fine particles in the exhalation are electrically sucked into the sheet body 13a. For this reason, the adsorption | suction performance of microparticles | fine-particles can be improved.
As shown in FIG. 15, during intake, the main body sheets 3 and 3 are closed due to a decrease in atmospheric pressure in the internal space 21, and the inflow of outside air from the gap 11 into the internal space 21 is suppressed.
Since most of the inhalation passes through the main body sheet 3, fine particles (such as body fluid droplets and pollen) in the outside air are captured by the main body sheet 3.

Second Embodiment
FIG. 17 is a perspective view of a mask 20 according to the second embodiment of the present invention. The mask 20 is a general mask (a mask having a general shape). In the following description of the embodiments, the same reference numerals are given to the already described configurations, and the description may be simplified or omitted.
The mask 20 is different from the mask 10 shown in FIGS. 1 to 3 and the like, and the upper edge 1d of the mask main body 1 is at a relatively low position. In the illustrated example, the upper edge 1d is a line connecting the eyes 63a. It is located below L1. Other configurations of the mask 20 can be the same as those of the mask 10.
In the mask 20, similarly to the mask 10, it is possible to improve the decrease in oxygen concentration in the internal space 21 without reducing the capture performance.

<Third Embodiment>
FIG. 18 is a perspective view of a mask 30 according to the third embodiment of the present invention. FIG. 19 is an enlarged view of a main part of the mask 30. FIG. 20 is a side view of the mask 30 in a folded state. FIG. 21 is a cross-sectional view of the end non-joining portion 17 at the front side edge portion of the mask 30. FIG. 22 is a cross-sectional view showing the operation of the end non-joining portion 17. FIG. 23 is an enlarged view of a main part showing a state where the mask 30 is mounted on the user's face.

As shown in FIGS. 18 to 21, in the mask 30, a portion including the upper end portion 3 f (the upper end portion of the overlapping portion 4) of the front side edge portion 3 a of the main body sheet 3 is the end non-joining portion 17. Except for this, the configuration is the same as the mask 10 of the first embodiment shown in FIGS.

In the end non-joining part 17, since the main body sheets 3 and 3 are overlapped but not joined to each other, the posture is easily changed when a force is applied.

For this reason, as shown in FIG. 22, when force in a direction away from each other (left and right direction in FIG. 22) is applied to the main body sheets 3, 3, the posture of the front side edge 3 a is bent due to the bending elasticity of the main body sheet 3. It changes so that an angle becomes small. For example, in the state shown in FIG. 21, the front side edge 3a is bent substantially perpendicularly to the other parts, but in the state shown in FIG. 22, the bending angle is small.
In the end non-joining portion 17, the front side edges 3a and 3a can be in a posture in which only the front edges 3g and 3g are in contact with each other and the other parts are separated from each other. That is, the front side edge portions 3a and 3a are opened to leave the front edges 3g and 3g.

As shown in FIGS. 22 and 23, the end non-joining portion 17 of the mask 30 attached to the face of the user 60 has a form opened to the side leaving the front edges 3 g and 3 g. The face 60a, for example, a complex-shaped region 61a (a region that varies in a complicated manner depending on the person) extending from the eye 63a to the top of the nose 61 is contacted. The end non-joining portion 17 covers at least the eye 63a and the vicinity thereof in a surface-contact manner.
Since the end non-joining portion 17 is in close contact with the complex shape region 61a in a state of spreading along the face 60a, the end non-joint portion 17 is in contact with the complex shape region 61a with a large contact area, and the heat retaining effect in the complex shape region 61a is enhanced. In particular, it can prevent and alleviate symptoms of allergic diseases such as hay fever such as the eyes and upper nose. In particular, the end non-joining portion 17 covers the eye 63a and the vicinity thereof, and by keeping this region warm, particularly allergic diseases (itching, runny nose, etc.) such as the eye and the upper nose can be effectively prevented and manifested. Can be relaxed.

In the mask 30, since the contact area of the main body sheet 3 (front side edge 3a) with the face 60a is increased, the pressing force applied to the face 60a is dispersed, so that discomfort of the user 60 can be suppressed. .
Further, as shown in FIG. 23, the force applied by the upper end 5a of the joint portion 5 to the face 60a is relieved by the bending elasticity of the end non-joint portion 17 in contact with the face 60a in the open form. Therefore, as shown in FIG. 24, compared with the conventional product in which the joint portion 25 reaches the upper end of the front side edge portion 3a, it is possible to suppress discomfort of the user 60 due to the joint portion 5 hitting the face 60a.

Except for this, it has the same configuration as the mask 30 of the third embodiment shown in FIGS.
The notch 18 is a notch extending from the upper end of the front side edge 3a to the length direction of the front side edge 3a, and its length L3 can be set to 5 to 7 mm, for example. The width of the notch 18 can be the same width as the overlapping portion 4.
The inner edge 18a (side edge) of the notch 18 is formed in a direction along the front edge 3a, and can be said to be the front edge of the main body sheet 3 in the portion where the notch 18 is formed. The upper end portion 3h of the main body sheet 3 that is a portion including the front side edge portion 18a is convex upward, and when the mask 20 is attached, the upper end portions 3h, 3h of the pair of main body sheets 3, 3 are It becomes a form separated from each other.

  In the mask 40, since the upper end portions 3h of the main body sheet 3 are not joined to each other, the upper end portions 3h, 3h are in an open form, and a complex shape region 61a (from a person to the upper portion of the nose portion 61) Differently, the region undulates in a complicated manner) with a large contact area in close contact with the surface. Therefore, the heat retaining effect in the complex shape region 61a can be enhanced, and prevention of allergic diseases such as hay fever, etc., and symptom relief can be achieved.

<Twelfth embodiment>
FIG. 34 is a perspective view of a mask 10F according to the twelfth embodiment of the present invention.
The mask 10F has the same configuration as that of the mask 10 shown in FIGS. 1 to 3 and the like except that the mask main body 1 is composed of one sheet.

In the mask of the present invention, the mask body is selected from the group consisting of far-infrared radiation material, metal foil, iron powder-containing heat generating material, blood circulation accelerator, negative ion generating material, magnet, hygroscopic heat generating material, and heat storage sheet. It is good also as a structure containing 1 or 2 or more (henceforth a functional material).
For example, at least one sheet body constituting the main body sheet may include the functional material.

The far-infrared radiation material is a material that can be converted into far-infrared rays by receiving heat radiated from the human body or the outside. For example, Al ₂ O ₃ , SiO ₂ , TiO ₂ , Cr ₂ O ₃ , ZrO ₂ , MgO, So-called far-infrared rays such as metal oxides such as Fe ₂ O ₃ ; carbon compounds such as SiC, TiC, ZrC and B ₄ C; nitrides such as Si ₃ N ₄ , BN and AlN; or a composite of two or more thereof Radioactive ceramics can be used. The use of far-infrared radiation material can enhance the heat retention effect.
Examples of the metal foil include aluminum foil, which can be used by being laminated on a nonwoven fabric constituting the main body sheet. The heat retention effect can be enhanced by using metal foil.

The iron powder-containing exothermic material uses heat of reaction when the iron powder reacts with oxygen and moisture in the air, and includes, for example, iron powder, sodium chloride, and, if necessary, an oxidation catalyst. The iron powder-containing heat generating material can be used as a heating element in a sheet shape enclosed in a bag. The warming body reacts with oxygen in the air when taken out from the sealed container at the time of use and generates heat, thereby heating the inside of the mask body.
As the blood circulation promoter, for example, methyl salicylate, camphor, menthols, various perfume oils, cypress oil, hiba oil, capsicum tincture and the like can be used. When a blood circulation promoter is used, a volatile component can penetrate into the skin and promote blood circulation in a subcutaneous capillary.
As the negative ion generating material, for example, tourmaline powder or electrolyzed alkaline ionized water can be used.
The magnet can promote blood circulation by applying a magnetic force to subcutaneous capillaries.

The hygroscopic exothermic material has a function of generating heat by absorbing moisture, and includes, for example, an acrylate-based material and a cellulose-based material. The moisture-absorbing heat generating material generates heat by absorbing sweat sweated from the face, for example.
As the heat storage sheet, a sheet-shaped heat storage agent such as CMC, PVA, or acrylic acid polymer enclosed in a bag can be used. The heat storage sheet can be heated by a microwave oven or the like. A user's face can be heated by using a thermal storage sheet for a mask. Unlike the iron powder-containing heat generating material, the heat storage sheet can be used repeatedly because the used product can be reused if heated using a microwave oven or the like.

The functional material (one or two or more selected from the group consisting of far-infrared radiation material, metal foil, iron powder-containing heat generating material, blood circulation promoter, negative ion generating material, magnet, hygroscopic heat generating material, and heat storage sheet) It can be used by laminating or impregnating part or all of the mask body. Although the use position (for example, attachment position of a heating body) of the said functional material is not specifically limited, It is preferable to use it for the eye-head heat retention part 1c (nasal part heat retention part). The usage form of the functional material (for example, the attachment form of the heating body) is not particularly limited, and may be any form.
Prevention, alleviation of symptoms, and allergic diseases such as hay fever can be achieved by heating, heat retention, blood circulation promotion, and the like by using the functional material.

<13th Embodiment>
FIG. 35 is a sectional view of a mask 10G according to the thirteenth embodiment of the present invention.
The mask 10G is a usage example of the functional material.
The main body sheet 3 of the mask 10G has a laminated structure in which sheet bodies 13a made of a plurality of nonwoven fabrics or the like are laminated.
An intervening layer 13b is interposed between the sheet bodies 13a and 13a. The intervening layer 13b is a layer containing the functional material.

The mask of the present invention can be enclosed in a bag to form a mask enclosure. In particular, when the functional material is used, the functional material can be prevented from being deteriorated by enclosing it in a bag.
A bag that can accommodate the mask in a sealed state is used. As the bag, those having gas barrier properties are suitable. For example, when using an iron powder-containing heat generating material, it is necessary to prevent the material from coming into contact with oxygen in order to prevent the material from generating heat before using the mask. This is effective for breaking the contact between oxygen and the above material.
Moreover, as a bag, what has a moisture barrier property can be used. For example, when using a hygroscopic exothermic material, it is necessary to prevent the material from touching moisture in order to prevent the material from generating heat before using the mask. This is effective for breaking contact with the above material.
Examples of materials having high gas barrier properties and moisture barrier properties include polypropylene, polyethylene, and polymethylpentene. For this reason, the bag which consists of 1 or 2 or more among polypropylene, polyethylene, and polymethylpentene can be used.
Polypropylene, polyethylene, and polymethylpentene have high heat resistance, and even when heated in a microwave oven, harmful substances (such as harmful gases) are not easily generated. For this reason, it is suitable when a heat storage sheet is used for the mask and the heat storage sheet is heated in a microwave while the mask is put in a bag.
FIG. 36 shows a mask enclosure 81, (a) is a plan view, and (b) is a cross-sectional view. The mask enclosure 81 includes a mask 10 and a bag 80 enclosing the mask 10. The mask 10 can be used after being taken out of the bag 80.

The present invention provides a mask using the functional material. When the functional material is used, there may or may not be a non-joining portion. As a mask without a non-joining part, the mask 110 shown in FIG. 37 can be illustrated. The mask 110 has a mask main body portion 101 composed of a pair of main body sheets 103 in which front side edge portions 103 a are continuously joined over the entire length, and an ear hooking portion 102. The main body sheet 101 and the ear hook 102 are continuously joined over the entire length of the edge.
The functional material can be used as the interposed layer 13b in the structure shown in FIG. As shown in FIG. 36, the mask 110 can be enclosed in a bag 80 to form a mask enclosure 81. When using a heat storage sheet, the heat storage sheet can be heated by processing the mask 110 with a microwave oven. The mask 110 can also be processed in a microwave oven in the bag 80. The configuration of the first to thirteenth embodiments described above can be adopted for the mask 110 except for the non-bonded portion.
The mask 110 includes a mask main body portion 101 made of a sheet and ear hooking portions 102 made of sheets provided on both sides of the mask main body portion 101, and the functional material is used for the mask main body portion 101. . The functional material can be used by being laminated on a part or all of the mask main body 101. The functional material may be attached to the mask main body 101 in any form.
