FIG. 7 is a cross-sectional view showing the operation of the end non-joining portion. FIG. 8 is an enlarged view of a main part showing a state where the mask 10 is worn on the face of the user 60.
In the following description, the left side in FIG. 3 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.

As shown in FIGS. 1 to 6, 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) are joined to each other.
As shown in FIG. 3, the main body sheet 3 includes a front side edge 3 a that is curved in a substantially arc shape, an upper edge 3 d that descends backward, and a substantially linear lower edge 3 e that rises backward. And a substantially straight rear side edge 3b (the other side 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. The length of the rear side edge 3b (the vertical dimension in FIG. 3) is shorter than that of the front side edge 3a.

As shown in FIGS. 3 to 6, the front side edge portions 3 a and 3 a of the pair of main body sheets 3 and 3 are joined to each other at the joint portion 5 by overlapping the inner surfaces 3 c and 3 c along the length direction. .
As shown in FIG. 1 to FIG. 3 and FIG. 6, the overlapping portion 4 of the front side edge portions 3a and 3a is a belt-like region having a substantially constant width extending over the entire length of the front side edge portion 3a. This is a region having a constant width from the front edge 3g (one side edge).
As shown in FIGS. 3 and 6, the joint portion 5 is a portion that joins the inner surfaces 3 c and 3 c of the main body sheet 3, and extends along the length direction of the front side edge portion 3 a.

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.
The joint portion 5 can join the main body sheets 3 to each other over the entire width of the overlapping portion 4, and can also join parts of the main body sheet 3 in the width direction 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 FIGS. 4 to 6, the front side edge 3 a of the main body sheet 3 has a form protruding forward when the user 60 is wearing it.

As shown in FIG. 4, 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 the 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. 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 (a region that varies depending on the person and undulates in a complex manner) over the top of 61 in a surface-contact manner. 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. 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 upper end 5a of the joint portion 5 is located in a height range from a line L1 connecting the eyes 63a of the user 60 to the upper end 61b of the nose 61 of the user 60 at the time of wearing.
A convex portion 1d at the lower part of the mask main body 1 (a portion located at a position lower than the lower end of the rear side edge 3b of the main body sheet 3) is a portion protruding downward from the main body main portion 1A. 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.

The portions including the upper end portion 3f (the upper end portion of the overlapping portion 4) of the front side edge portion 3a of the main body sheet 3 are not joined to each other. This non-joined portion is referred to as an end non-joint portion 17. Although the main body sheets 3 and 3 are overlapped at the end non-joining portion 17, they are not joined to each other.
The end non-joining portion 17 is located at a position higher than the line L1 connecting the eyes 63a of the user 60 when worn. The end non-joining part 17 should just be in the position where at least one part is higher than the line L1. That is, all of the end non-joining portions 17 may be higher than the line L1, or a part of the end non-joining portions 17 may be higher than the line L1.

As shown in FIGS. 3 and 6, the end non-joining portion 17 is a non-joining portion extending from the upper end of the front side edge 3a to the length direction of the front side edge 3a, and its length L2 is, for example, 5 to 5 It can be 7 mm. 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. 7, when a force in a direction away from each other (left and right direction in FIG. 7) 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. 6, the front side edge 3a is bent substantially perpendicular to the other parts, but in the state shown in FIG. 7, the bending angle is small.
Thereby, in the edge part non-joining part 17, only the front edges 3g and 3g can mutually contact the front side edge parts 3a and 3a, and the other part can take the attitude | position spaced apart 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. 7 and 8, the main body sheet 3 of the mask 10 attached to the face of the user 60 is open to the side leaving the front edges 3 g and 3 g at the end non-joining portion 17. The face 60a of the user 60, for example, a complex-shaped region 61a (a region that varies in a complicated manner and varies depending on the person) from the eye 63a to the top of the nose 61 is in close contact with the user. 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 contacts the complex shape region 61a with a large contact area, and the heat retaining effect in the complex shape region 61a is obtained. 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 part 17 covers the eye 63a and its vicinity area in a surface-tight manner, and by keeping the area warm, it is particularly effective for allergic diseases (itching, runny nose, etc.) such as the eye head and the upper nose. Can prevent and relieve symptoms.

FIG. 17 is a schematic diagram showing the structure of the lacrimal organ. Tears are secreted from the lacrimal gland 201, flow along the surface of the eyeball 210 with pollen and dust, etc., pass through the lacrimal passages such as the canalicular tubule 202, lacrimal sac 203, and nasolacrimal duct 204 close to the eye 63a, and discharged into the nasal cavity as a runny nose. Is done. When hay fever develops, the nasal mucous membrane becomes inflamed, and particularly the eyelid 63a becomes prominent and edema occurs, the tear duct 202 is blocked, and tear flow is inhibited. When the flow of tears is inhibited, pollen and dust are not discharged into the nasal cavity, so they stay in the eye 63 for a long time, the allergen component elutes in the tears and stimulates the mucous membrane of the eye, causing inflammation, Causes itchy eyes and tears (condensation of a large amount of tears) due to conjunctivitis.
The mask 10 shown in FIG. 1 and the like covers and keeps the surface of the complex shape region 61a (a region that varies depending on the person and undulates in a complicated manner) from the eye 63a to the upper portion of the nose 61 by the end non-joining portion 17 in a surface contact manner. In this way, the effect of keeping the lacrimal passage such as the lacrimal sac 203 and the nasolacrimal duct 204 around the lacrimal canal 202 is enhanced. In particular, the inflammation and edema of the lacrimal canal 202 are suppressed, the blockage is eliminated, and the tears are distributed. Make it possible. If tears can be circulated, allergen components contained in pollen and dust are discharged as a runny nose into the nasal cavity through the lacrimal passages such as the lacrimal canal 202, lacrimal sac 203, and nasolacrimal duct 204 before elution. For this reason, the symptoms of hay fever such as conjunctivitis and tears can be suppressed.

In the mask 10, since the contact area of the front side edge portion 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. 8, a force in a direction away from the face 60 a acts on the main body sheet 3 by the bending elasticity of the end non-joining portion 17 that is in contact with the face 60 a in the open form. For this reason, the force which the upper end 5a of the junction part 5 applies to the face 60a is relieved. Therefore, as shown in FIG. 9, 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.

  As shown in FIGS. 1, 3 and 4, the ear hook 2 is formed to extend rearward from the rear side edge 3 b of the main body sheet 3 of the mask main body 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.

The ear hook 2 can be a non-woven fabric using synthetic fibers made of a polyolefin-based material or a polyester-based material. 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. 1 to 3, the inner surface of the rear side edge 3 b of the main body sheet 3 is overlapped with the outer surface of the front edge 2 a of the ear hook 2 along the length direction. In the portion 8, the main body sheet 3 and the ear hook 2 are joined to each other. For welding the main body sheet 3 and the ear hook 2, heat welding or an adhesive can be used.

As shown in FIG. 4, 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 example shown in the figure, the insulative part 1c (nasal part insulative part) of the mask main body 1 has a complex shape area 61a (an area that varies depending on the person and undulates complicatedly) extending from the inguinal part 63a to the upper part of the nose part 61 in a surface-contact manner. The upper end 5a of the joint portion 5 of the mask main body 1 covers the upper end 61b of the nose portion 61 protruding from the main body main portion 1A. 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. The thermal insulation section 1c reaches a position higher than the line L1 that connects the temporal eyes 63a. Specifically, the upper end 1a of the mask main body 1 is located higher than the line L1. In addition, the height direction here is the upper part of FIG. 4, and the position higher than the line L1 means being located above the line L1 in this figure.

FIG. 10 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. 4, 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.
In particular, the end non-joining portion 17 that is in an open form is in close contact with a complex shape region 61a (a region that varies depending on the person and undulates complicatedly) from the eye head 63a to the upper portion of the nose 61 with a large contact area. By abutting and in close contact with the complex shape region 61a, the heat retaining effect can be enhanced, and in particular, allergic diseases such as hay fever such as the eyes and nose can be prevented and symptoms can be mitigated.

In the mask 10, the end non-joining portion 17, which is a portion including the upper end portion 3 f of the main body sheet 3, is in an open form when worn, and a complex shape region 61 a extending from the eye 63 a to the upper portion of the nose 61 (depending on the person, A complex undulating region) is brought into close contact with a large contact area, thereby increasing the heat-retaining effect, and in particular, preventing and alleviating symptoms of allergic diseases such as hay fever such as the eyes and nose.
Moreover, since the contact area with respect to the face 60a of the main body sheet | seat 3 (front side edge part 3a) becomes large, the pressing force applied to the face 60a is disperse | distributed. Further, the force applied to the face by the upper end 5a of the joint portion 5 is alleviated by the bending elasticity of the end non-joint portion 17 that is in contact with the face 60a in the open configuration. Therefore, the discomfort of the user 60 due to the joining portion 5 hitting the face 60a can be suppressed.
Further, as shown in FIG. 17, since the end non-joining portion 17 is easily deformed, a belt-like shape extending from the end non-joining portion 17 along the upper edge portion 3d toward the rear side edge portion 3b. The upper edge region 19 is also easily deformed and the posture change is likely to occur. For this reason, the upper edge area | region 19 becomes the attitude | position in alignment with the face 60a, and contact | abuts to the face 60a surface-contactingly, and can improve the heat retention effect of an abutting part.

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.
FIG. 11 shows another example of the main body sheet. The main body sheet 3 shown here 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.

Second Embodiment
In the mask 10 shown in FIG. 1 to FIG. 4 and the like, the end non-joining portions 17 are hardly separated from each other. However, as shown in FIG. 12, a part of the end non-joining portions 17 may be separated from each other. It is.
The end non-joining portion 17 abuts in a surface contact with a complex shape region 61a (a region that varies depending on the person and undulates complicatedly) from the eye 63a to the upper portion of the nose 61 with a large contact area. By increasing the heat-retaining effect, it is possible to prevent and alleviate symptoms, in particular, allergic diseases such as hay fever such as the eyes and nose. In particular, the end non-joining portion 17 covers the eye 63a and the vicinity thereof, and keeping this region warm can effectively prevent and alleviate symptoms of allergic diseases.

<Third Embodiment>
FIG. 13 is a side view of the mask 20 in a folded state according to the third embodiment of the present invention. FIG. 14 is a perspective view showing a state in which the mask 20 is mounted on the user's face.
The mask 20 has a notch 18 formed at the upper end 3f of the front side edge 3a of the main body sheet 3 (the upper end of the overlapping portion 4), so that the portion including the upper end 3h of the main body sheet 3 is not mutually non-existent. Except for being joined (end non-joined portion 18A), it has the same configuration as the mask 10 of the first embodiment shown in FIGS.
As shown in FIG. 13, 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 is, for example, 5 to 7 mm. it can. 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 end non-joining portion 18A of the main body sheet 3 which is a portion including the front side edge portion 18a is convex upward, and when the mask 20 is attached, the end non-end portions of the pair of main body sheets 3 and 3 are not provided. The joint portions 18A and 18A are separated from each other.

As shown in FIG. 14, in the mask 20, since the part (end part non-joining part 18A, 18A) containing the upper end part 3h of the main body sheet | seat 3 is mutually non-joined, the end part non-joining part 18A, 18A is open to the side, and a complex contact area 61a from the eye 63a to the upper part of the nose 61 (a region that varies depending on the person and undulates in a complex manner) is brought into close contact with a large contact area. The heat retaining effect can be enhanced by contacting the region 61a with a large contact area.
Accordingly, it is possible to prevent and alleviate symptoms of allergic diseases such as hay fever in which symptoms appear in the eyes and nose. In particular, the end non-joining portions 18A and 18A cover the eye head 63a and the vicinity thereof, and keeping this region warm can effectively prevent and alleviate symptoms of allergic diseases such as the eye head and nose.

FIG. 15 is a perspective view showing a state in which the mask 30 according to the fourth embodiment of the present invention is mounted on the user's face.
In the mask 30, the front side edge portions 3a and 3a of the main body sheets 3 and 3 are joined to each other by a plurality of joining portions 35 (joining portions on one side). The plurality of joint portions 35 are separated from each other in the length direction of the front side edge portion 3a by one or a plurality of intermediate non-joint portions 36 (one-side non-joint portions). In the example of illustration, the junction part 35 is a part of the substantially constant width formed intermittently over the full length of the front side edge part 3a. The upper end 35 a of the joint portion 35 can be locked to the upper end 61 b of the nose portion 61.

The intermediate non-joining portion 36 is a portion between the adjacent joining portions 35 and 35 where the main body sheets 3 and 3 are not joined to each other.
In the intermediate non-joining portion 36, the main body sheets 3 and 3 are overlapped but are not joined to each other. For this reason, the gap between the main body sheets 3 and 3 can be ventilated in the intermediate non-joining portion 36, and the gas in the internal space of the mask main body portion 1 can be discharged to the outside through this gap. Further, as will be described later, the inflow of outside air can be suppressed during intake.

The inner surface of the rear side edge portion 3b of the main body sheet 3 is overlapped with the outer surface of the front edge portion 2a of the ear hook portion 2 along the length direction. 2 are mutually joined by the some back junction part 45 (joint part of the other side).
The plurality of rear joining portions 45 are formed to be separated in the length direction of the rear side edge portion 3b by one or more rear non-joining portions 46 (non-joining portions on the other side).

When the pressure in the internal space 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 a gap in the intermediate non-joining portion 36 of the front side edge 3 a of the main body sheet 3. The other part of the exhalation is discharged to the outside through a gap in the rear non-joining portion 46 of the overlapping portion 8 between the rear side edge 3b of the main body sheet 3 and the front edge 2a of the ear hook 2.
For this reason, exhalation does not fill the internal space, and a decrease in oxygen concentration in the internal space can be improved. Therefore, the health disturbance of the user 60 can be reduced.

When exhaled air is discharged from the gap in the intermediate non-joining portion 36, the main body sheets 3 and 3 are less likely to be separated from each other due to a decrease in atmospheric pressure due to the air flow. Since the main body sheet 3 is a structure made of fibers, the inner surface 3c (see FIG. 7) is not a smooth surface microscopically, but has irregularities, so that fine particles (such as body fluid droplets) in the exhalation are not joined. Is adsorbed on the inner surface 3c, and the release to the outside is suppressed.
Even when exhaled air is discharged from the gap at the rear non-joining portion 46, fine particles (such as body fluid droplets) in the exhalation are adsorbed on the inner surface 3c of the non-joining portion 46 and the outer surface of the ear hooking portion 2 to suppress the release to the outside. It is done.
Since the intermediate non-joining part 36 and the rear non-joining part 46 have a sufficient width, the fine particles in the exhalation can be effectively adsorbed and released to the outside.

During intake, the front side edge portions 3a and 3a of the main body sheets 3 and 3 of the intermediate non-joining portion 36 are closed due to a decrease in atmospheric pressure in the internal space, and no external air flows into the internal space from the gap.
Similarly, in the overlapping portion 8 between the rear side edge portion 3b of the main body sheet 3 and the front edge portion 2a of the ear hook portion 2, the main body sheet 3 and the ear hook portion 2 are closed in the rear non-joining portion 46, and the gap The outside air does not flow into the internal space.
For this reason, most of the outside air introduced into the internal space as intake air passes through the main body sheet 3. At this time, fine particles (eg, pollen) in the outside air are captured by the main body sheet 3, so that the capturing performance is not deteriorated.
Therefore, the mask 30 can improve the decrease in oxygen concentration due to the expiration of the internal space without lowering the capture performance, and reduce the health disturbance of the user 60.

<Fifth Embodiment>
FIG. 16 is a main part enlarged view showing a state in which the mask 40 according to the fifth embodiment of the present invention is mounted on the user's face.
The mask 40 has the same configuration as the mask 10 of the first embodiment shown in FIGS. 1 to 3 and the like except that an ear cover 41 that covers the ear 65 is provided on the outer surface side of the ear hook 2.
As the ear cover 41, a non-woven fabric having substantially the same outer shape as the ear hook 2 can be used. By using the ear cover 41, the ear 65 (for example, the pinna and the external auditory canal) can be kept warm and fine particles in the outside air can be removed.
Therefore, it is possible to enhance the heat retaining effect of the auricle and the external auditory canal, and to remove fine particles in the outside air, thereby preventing ear allergic diseases and alleviating symptoms.

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

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. The heat retention effect can be enhanced by using the heat storage sheet.

These materials (one or two or more selected from far-infrared radiation materials, metal foil, iron powder-containing heat generating materials, blood circulation promoters, negative ion generating materials, magnets, hygroscopic heat generating materials, and heat storage sheets) It can be used by laminating or impregnating part or all of it. Although the use position (for example, attachment position of a heating body) of the said material is not specifically limited, It is preferable to use especially for the eye head heat retention part 1c (nasal part heat retention part). The method for using the material (for example, a method for attaching a warming body) is not particularly limited, and any method may be used.
By using the above-mentioned materials, it is possible to prevent and alleviate the symptoms of allergic diseases such as hay fever, such as the eyes and nose, by heating, keeping warm and promoting blood circulation.
