Description

Mask

This creation is about a mask.

In recent years, the functions of masks covering eyes and the eyes have been diversified, and various masks have been developed. For example, a mask having a warming effect is used in which a heat generating body which contains an oxidation heat generated by an oxidation reaction of an oxidizable metal is contained inside. Among them, eye masks, which are used to warm the eyes of the wearer with a heating element and are used to hook a pair of ear-hanging portions to the left and right ears, are widely used because they are lightweight and easy to use.

On the other hand, expectations for eye masks continue to increase. For example, Patent Document 1 discloses that the positions of the ear-hook connecting portions, the shape of the openings, and the slits are specified from the viewpoint of easily hooking the ear-hook on the ears and easily fitting the mask body to the face.

That is, the present invention provides a mask including: a mask body covering two eyes; a heating element provided on the mask body; and a pair of hanging ears respectively corresponding to the length direction of the mask body Both ends are joined and held so as to cover the wearer's eyes with the mask body; and the following conditions are satisfied.
(condition)
The ear-mounting part has an opening for ear-mounting,
In a direction perpendicular to a maximum length direction of the opening portion, a minimum value of a width of a portion of the hanging ear portion located above the opening portion is set to Da (cm), and the hanging ear portion is set to Da (cm). When the minimum value of the width of the portion lower than the opening is Db (cm), Da / Db is 1.3 or more and 15.0 or less.
When the length from the point where the straight line including the Db intersects with the outer edge of the lower side of the ear part to the outer edge of the joint part of the ear part and the mask body part is Dc (cm), Dc is 1 cm to 4.5 cm.

In recent years, the use of eye masks with a warming effect has been diversified, not only in the form of the wearer standing up and using it, but also in the form of supine and side use. In this case, in order to fully obtain the warming effect, the eye mask is required to fit the wearer as much as possible. Therefore, the prior eye mask as disclosed in Patent Document 1 still has room for improvement in fit.

Here, in order to improve the fitting feeling of the eye mask, and in the case where no special improvement is made, for example, the length in the width and width direction of the eye mask is shortened so that the warming device is in close contact with the face of the wearer, it is generated by the ears. The stress tends to be high on the part of the wearer's ears or behind the ears, which tends to produce a sense of pressure.
Therefore, the author has worked hard on the viewpoint of reducing the pressure on the ears or the pressure behind the ears and suppressing the displacement of the mask even in the side-lying position, and found that: When covering the mask, do not press the range from the eye end of the wearer to the sun hole, the eye end to the earlobe, and press the vicinity of the eyebrow of the wearer tightly at the same time, thereby effectively suppressing the lateral shift of the mask to improve the fit and reduce Oppression. Furthermore, research was advanced to solve the problems of obtaining a good balance of fit and oppression in the mask and evenly heating a wide range in the side-lying position to enhance the sense of relaxation throughout the body, It turns out that the mask meets certain conditions is effective as a pointer to solve this problem, thus completing this creation.

According to the present invention, it is possible to provide a mask which can obtain a good balance between a feeling of fit and a sense of pressure. In addition, the mask of this creation will warm a wider area than before, and with the improvement of the fit, a uniform warmth can be obtained, thereby further improving the relaxation of the whole body.

Hereinafter, an embodiment of this creation will be described using drawings. In addition, in all the drawings, the same constituent elements are assigned the same symbols, and descriptions thereof are appropriately omitted. In addition, breathability has the same meaning as breathability.

[Warming appliance]
First, an example of the heating device 50 according to this embodiment will be described with reference to FIGS. 1 to 3.
The heating device 50 of this embodiment is a so-called eye mask with a warming effect, and is used to cover the wearer's eyes with the cover body portion 51 and heats the heating body 100 from one of the cover body portions 51 provided there Water vapor to a specific temperature is imparted to the eyes and those around them. However, the aspect of the mask is not limited to this embodiment.

As shown in FIG. 1, the heating device 50 includes a cover body portion 51 and a pair of ear-mounting portions 52 (52L, 52R) each formed with an ear insertion hole 54 (54L, 54R).

The heating device 50 is worn by hooking each of the ear-mounting portions 52 to the ears of the wearer and covering the eyes of the wearer with the cover body portion 51. In this wearing state, warm steam generated from the heating element 100 described below is applied to the eyes of the wearer.

FIG. 2 is a plan view schematically showing a state of the heating device 50 before the ear ear portion 52 is opened. In this figure, a pair of ear-mounting portions 52 are folded toward each other toward the inner side of the heating device 50 and are joined to each other at the longitudinal center portion of the mask body portion 51. Perforated or half-cut grooves are provided in the areas where they are joined. That is, perforations or half cuts are provided in such a way that one pair of the hanging ear portions 52 are formed in half, and the wearer cuts them apart, thereby obtaining the hanging ear portions 52L and 52R. Then, by turning the ear-mounting portion 52L and the ear-mounting portion 52R outward, the state shown in FIG. 1 can be obtained. As shown in FIG. 1, when the ear-mounting portion 52 is opened outward from the mask body portion 51, the ear-mounting portion 52 has a H shape in a plan view. In addition, when the ear-mounting portion 52 is opened outward from the mask main body portion 51, the hole 52 extends obliquely downward with respect to the longitudinal direction of the mask main body portion 51.
By adopting such an arrangement, the mask body portion 51 is more easily adhered to the face when worn.

FIG. 3 is an exploded perspective view of the heating device 50 shown in FIG. 1. As shown in FIG. 3, the mask body portion 51 is composed of a bag body 53, and a pair of heat generating bodies 100 are provided inside the bag body 53.

The mask body portion 51 has a horizontally long shape having a longitudinal direction X and a width direction Y orthogonal to the mask body portion 51, and is almost bilaterally symmetrical. In addition, the mask body portion 51 is made of a flexible and flexible sheet, and may or may not have stretchability. However, the heating device 50 is pressed tightly near the eyebrows to make people feel the patch more strongly. From the viewpoint of synergy, it is preferable to have elasticity.

The bag body 53 constituting the mask body portion 51 includes a first bag body sheet 531 located on the side closer to the wearer's skin surface and a second bag body sheet 532 located on the side away from the wearer's skin surface. Here, the first bag body sheet 531 and the second bag body sheet 532 are provided so as to sandwich the heating element 100 described below.

The first bag body sheet 531 has the same shape as the second bag body sheet 532, and has a substantially oval shape. The outer shape of the first bag body sheet 531 and the second bag body sheet 532 constitute the outer shape of the mask body portion 51. The bag body 53 is formed by overlapping the first bag body sheet 531 and the second bag body sheet 532 and joining at least a part of the peripheral edge portions thereof and joining the central portion in the Y direction in the X direction. In order to join the 1st bag body sheet 531 and the 2nd bag body sheet 532, a hot-melt adhesive can be used, for example. The heat generating body 100 may be fixed to the bag body 53 by an adhesive, heat sealing, or the like.

The first bag body sheet 531 and the second bag body sheet 532 are preferably those capable of sufficiently supplying air to the internal heating element 100, and for example, a fibrous sheet represented by a nonwoven fabric can be used. For example, one kind or two or more kinds selected from a needle-punched nonwoven fabric, a hot-air nonwoven fabric, and a spunbond nonwoven fabric can be used.

A substantially V-shaped notch portion 57 (notch portion 571) is formed in the bag body 53 at the position of the central portion of the two long sides extending in the Y direction. , Notch 572). The notches 571 and 572 have different cut-in degrees. The notch portion 571 is located between or near the eyebrows of the wearer when the heating device 50 is worn. The notch portion 572 is located on the bridge of the nose of the wearer when the heating device 50 is worn. Therefore, in general, the cut-in degree of the notch portion 572 is larger than the cut-in degree of the notch portion 571.

Further, as shown in FIG. 1, in the bag body 53, a slit 32 connected to the notch portion 572 is located in a central portion of the bag body 53 and separates the heating body 100 from the lower end of the bag body 53. The slit 32 makes it easy to improve the wearing feeling.

In a state before use, the ear-mounting portion 52 in the warming device 50 is arranged on the first bag body sheet 531 as shown in FIG. 3. In a state before use, that is, a state in which the left and right hanging ear portions 52 are located on the first bag body sheet 531, the outline formed by the left and right hanging ear parts 52 is almost the same as the outline of the first bag body sheet 531.

The ear-mounting portion 52 has a function for holding the heating device 50 on the face of the wearer.
The ear-mounting portions 52 are used as a pair, and the ear-mounting portions 52L and 52R are attached to the respective ends in the longitudinal direction (X direction) of the mask body portion 51. More specifically, in the ear-mounting portion 52, when the side of the mask body portion 51 is used as the base end and the side away from the mask body portion 51 is used as the end, the area on the base-end side of the ear-mount portion 52 and the mask body The sheet (the first bag body sheet 531) on the wearer side of the portion 51 is joined.
Further, the ear-mounting portion 52L and the ear-mounting portion 52R each have a bonding area that overlaps with the mask body portion 51.

As shown in FIG. 1, the ear-mounting portion 52 includes a slit 31 that faces the hole 54 from the outer edge of the lower side. As a result, in the La direction described below, the width of the portion located below the hole 54 of the ear-mounting portion 52 and supporting the body portion 51 between the eye tip and the ear lobe when worn is reduced. In the heating device 50 of FIG. 1, the following Db (cm) is the length from the hole 54 to the upper end of the slit 31. In the heating device 50 of FIG. 1, the slit 31 is provided on a straight line including Db (cm).

In FIG. 1, the point where the slit 31 intersects the outer edge of the lower side of the ear-mounting portion 52 to the outer edge of the lower side of the ear-mounting portion 52 at the joint portion of the ear-mounting portion 52 and the mask body portion 51 is shown Length Dc (cm). In the heating device 50, Dc is 1 cm or more and 4.5 cm or less, which is a range in which the stress is easily concentrated in the ear part 52 during use. In other words, in this embodiment, the length of the straight line including Db (cm) from the joint between the ear mounting portion 52 and the mask body portion 51 in the outer edge of the lower side of the ear mounting portion 52 is 1 cm to 4.5 cm. Within the range, it intersects the outer edge of the lower side of the ear-mounting portion 52. Thereby, when the warming device 50 is worn, the stress can be effectively reduced, and the part of the ear-mounting portion 52 that touches the skin from the end of the eye to the earlobe is stretched and thinned, thereby reducing the feeling of pressure and improving the relative pressure. The hole 54 of the ear-mounting portion 52 is more extensible in the area below, and as a result, it is easy to maintain the fit and reduce the pressure.

From the viewpoint of improving the balance between the feeling of fit and the pressure, Dc is preferably 1.5 cm or more and 4.0 cm or less, and more preferably 1.8 cm or more and 2.5 cm or less.

The length of the slit 31 is not particularly limited, and it is preferably adjusted so that the following Db (cm) is within a proper range. For example, the length of the slit 31 may be 0.3 cm or more and 3.5 cm or less.
In addition, the slit 31 may be provided in a direction perpendicular to the extending direction of the hanging ear portion 52 or may be provided in a direction inclined with respect to the extending direction of the hanging ear portion 52. In view of the fact that the slice cut into the slit 31 is not easy to contact the skin of the user when the heating device 50 is worn, it is preferable that the slit 31 is provided in a direction perpendicular to the elongation direction of the ear 52.

From the viewpoint of easily controlling the balance between the feeling of fit and the feeling of pressure, the slit 31 is preferably provided only on the outer edge of the lower side of the ear-mounting portion 52. In other words, it is preferable that the ear-mounting portion 52 is not provided with a slit on the upper outer edge.

The slit 31 may be provided before the heating device 50 is used, or may be formed by the wearer breaking a preset dotted line portion before using the heating device 50.

The ear-mounting portion 52 is preferably extensible in the La direction. Specifically, in the heating device 50, the stress (N) when the ear part 52 is 100% stretched in the La direction described below is preferably 10 N or less, and more preferably 5 N or less. Thereby, the balance between the feeling of fitting and the pressure can be further improved, and the ear-mounting portion 52 can be easily extended during use, and the ear-mounting portion 52 can be easily hooked to the ear. Furthermore, from the viewpoint of obtaining a feeling of fit, the stress (N) at 100% elongation in the La direction of the ear portion 52 is preferably 1.5 N or more.

In addition, the stress (N) at the time of elongation in the ear part 52 can be measured by a method referring to JIS L1913.
That is, the width of the sample is set to 80 ± 10 mm, the initial length of the sample in the tensile tester is set to 55 ± 15 mm, and the measurement is performed at a tensile speed of 300 mm / min to extend in the La direction. Tensile strength at length (if it is a stress at 100% elongation, it is 100% of the initial length, if it is a stress at 50% elongation, it is 50% of the initial length).
Specifically, it will be described in the following embodiments.

The ear-mounting portion 52 may be composed of a single layer of sheet material, or may be a laminated body of a plurality of sheets. As the ear-mounting portion 52, a fiber sheet made of a fiber material such as a non-woven fabric can be used. The ear-mounting portion 52 may be the same material as the bag body 53 described above, or may be a material using a different material. From the viewpoint of easily controlling the balance between the feeling of fitting and the feeling of pressure, the ear-mounting portion 52 is preferably a non-woven fabric.

The planar shapes of the pair of hanging ear portions 52 are not particularly limited, and it is preferable that the planar shape on the right side and the planar shape on the left side of the mask body portion 51 when the mask body portion 51 is bisected by the longitudinal center line are respectively shape. For example, a substantially square shape is mentioned.

The hole 54 is a hole for hooking the ear-mounting portion 52 to the ear of the wearer, and is an opening penetrating the ear-mounting portion 52. The hole 54 is provided at approximately the center of the ear-mounting portion 52. The hole 54 is formed in a region other than a bonding region where the mask body portion 51 and the ear-mounting portion 52 are joined.

The shape of the hole 54 is not particularly limited. In FIGS. 1 and 2, the shape of the hole 54 is a long strip in the widthwise direction, and has a substantially triangular shape (droplet shape) with rounded corners that widen from the base end toward the end of the ears 52. Moreover, the hole 54 may be vertically symmetrical or asymmetrical. That is, the upper and lower curvature radii may be the same or different. In addition, when the ear 54 is opened outward from the mask body portion 51 with respect to the hole 54, the hole 54 extends downward with respect to the longitudinal direction of the mask body portion 51 and is inclined.

The hole 54 of the ear-mounting part 52 can also adjust the opening area to cope with any of the larger ears and the smaller ears, and the vicinity of the outline of the hole 54 is provided near the outline of the hole 54 to face the hanging One or more slits extending from the outer periphery of the ear portion 52. The slit can be opened as needed when hooking the ear-mounting portion 52 to the ear, so that the opening area can be adjusted.

[heating stuff]
Next, the heating element 100 included in the heating device 50 will be described. In this embodiment, a pair of heating elements 100 are disposed on the heating device 50, and each heating element 100 covers the eyes of the wearer.

The planar shape of the heating element 100 is substantially square. The rigidity of the heating body 100 is greater than the rigidity of the cover body portion 51, and the heating body 100 as a whole is less likely to expand and contract than the cover body portion 51.

FIG. 4 is a plan view showing an example of the heating element 100 according to this embodiment. 5 is a cross-sectional view taken along the line A-A of FIG. 4. The heat generating body 100 according to the present embodiment includes a heat generating portion 10 and a container 20 accommodating the heat generating portion 10.

The heat generating portion 10 includes an oxidizable metal, a carbon component, a water absorbent, water, a reaction accelerator, and the like.
Specifically, the heat generating portion 10 is a person who generates heat by an oxidation reaction of an oxidizable metal to give a warming effect, and a person having a performance of a heating temperature of 30 ° C. to 70 ° C. in the measurement according to JIS S4100 can be used. In addition, the heat generating portion 10 functions to generate water vapor by heating the contained water.

The oxidizable metal is a metal that generates an oxidation reaction heat, and examples thereof include powders or fibers of one or more metals selected from the group consisting of iron, aluminum, zinc, manganese, magnesium, and calcium.

The carbon component has a water-holding ability, an oxygen supplying ability, and a catalyst ability. For example, one or two or more materials selected from the group consisting of activated carbon, carbon black, acetylene black, and graphite can be used.

A water-absorbing agent can be contained in the heat generating part 10 to hold moisture, and the oxidation reaction of the oxidizable metal can be performed efficiently. As the water-absorbing agent, a polymer having water absorption or a powder having water absorption can be used.

In this embodiment, the heat generating portion 10 is shown in a sheet form, but the heat generating portion 10 may be in a powder form or in a sheet form. However, in terms of excellent use feeling, a sheet shape is preferred. Such a sheet-like heating element can be obtained by any method such as a method of making paper with fibers, a method of coating, and a method of compacting by pressing or the like.

From the viewpoint of obtaining moderate rigidity, the thickness of the heating portion 10 is preferably 0.2 mm or more, more preferably 0.4 mm or more, and even more preferably 0.5 mm or more. From the viewpoint of improving the operability, the thickness of the heating portion 10 is preferably 5 mm or less, more preferably 3 mm or less, and even more preferably 2 mm or less.
By setting the thickness of the heat generating portion 10 to the above range, it is possible to increase the heat generating effect and to make the heat generating body 100 a size that is easy to use. Moreover, since the heat generating part 10 has a moderate rigidity, it is possible to more strongly feel the fitting feeling when the heating device 50 is worn.
It should be noted that the thickness of the heat generating portion 10 indicates an average thickness.

Next, a description will be given of the containing body 20 constituting the heating body 100.
The container 20 is at least partially breathable and accommodates the heat generating portion 10. The storage body 20 can be configured by, for example, bonding the peripheral edge portions 203 of two sheets (the first storage body sheet 201 and the second storage body sheet 202) as shown in FIG. 5.
In addition, the first containing body sheet 201 is located on the skin side of the wearer more than the heat generating part 10, and the second containing body sheet 202 is located on the skin side of the wearer more than the heat generating part 10. When water vapor is supplied to the eyes or the skin by the warming device 50, from the viewpoint of efficiently imparting water vapor to human eyes or skin, the first container sheet 201 is preferably one having good air permeability. Sheet, on the other hand, the second container sheet 202 is preferably a sheet that lacks air permeability. That is, it is preferable that the second storage body sheet 202 is less air-permeable than the first storage body sheet 201, and more preferably, it is non-ventilated. In other words, the air permeability of the second container sheet 202 is preferably higher than the air permeability of the first container sheet 201.

When the heat generating part 10 is a person having a heat generating function based on the oxidation of an oxidized metal, the first container body sheet 201 is adjusted as described above in order to efficiently impart water vapor to the eyes or the skin using the heating device 50. In the case of the air permeability of the second storage body sheet 202, air is preferentially taken in from the first storage sheet 201 side in the heat generating section 10 to cause a heat reaction. Therefore, from the viewpoint of obtaining a balance between a feeling of fit and a fever reaction and moderately warming the eyes or the skin, the ventilation rate of the first storage sheet 201 is preferably 3,000 to 6,000 seconds / 100 ml, more preferably 4,000 ~ 6,000 seconds / 100 ml.

In addition, "air permeability" is defined by the value measured by JIS P8117, and the time when 100 ml of air at a constant pressure passes through an area of 6.45 cm ² .

As the air-permeable sheet, a porous sheet made of a resin or a sheet made of a resin having air holes can be used. For example, one or two or more of polyethylene, polypropylene, and an ethylene-vinyl acetate copolymer can be used. .

As the second container sheet 202, those which are substantially impervious to oxygen can be used, and for example, polyolefins such as polyethylene and polybutadiene, polyvinyl chloride, polyvinylidene chloride, polyester, polyether, and polyfluorene can be used. And one or more of polyamines.

In addition, since the heating device 50 of this embodiment has an oxidizable metal that is oxidized by oxygen, it is usually sealed in an oxygen barrier bag and stored.

The heating device 50 according to this embodiment includes a cover body portion 51 covering both eyes, a heating element 100 provided on the cover body portion 51, and a pair of mounting ear portions 52 (52L, 52R), and the like. It is joined to both ends in the longitudinal direction of the mask body portion 51 and is held so as to cover the eyes of the wearer with the mask body portion 51; and the following conditions are satisfied.
(condition)
The ear-mounting part 52 has a hole 54 for ear-mounting,
In a direction perpendicular to the maximum length direction of the hole 54, set the minimum value of the width of the portion above the hole 54 among the mounting ear portions 52 to Da (cm), and set the middle of the mounting ear portion 52 to Da (cm). When the minimum value of the width of the portion located below the hole 54 is set to Db (cm), Da / Db is 1.3 or more and 15.0 or less. A straight line including Db intersects with the outer edge of the lower side of the mounting ear portion 52. When the length from the point to the outer edge of the joint portion of the ear mounting portion 52 and the mask body portion 51 is set to Dc (cm), Dc is 1 cm or more and 4.5 cm or less.

Here, the maximum length of the hole 54 means the length La (cm) when no load is applied to the ear part 52 in a state before the heating device 50 is used. In the heating device 50, as shown in FIGS. 1 and 2, both ends of the hole 54 in the X direction are arc-shaped, and a straight line connecting the deepest points of the arcs is La (cm). The maximum length direction of the hole 54 means a direction parallel to the La direction.
When the La in the hole 54L is different from the La in the hole 54R, the La of the hole 54 is the average of the two. When the ear-mounting portion 52 has a slit extending from a portion of the outer edge of the hole 54 toward the outer edge of the ear-mounting portion 52, the slit is not included in the maximum length La. Further, in the case where the hole 54 is a mask formed by a cut-in having no opening area (for example, a T-shaped cut-in), a straight line corresponding to the vertices at both ends of the opening portion of the hole 54 extending in the La direction becomes La (cm)). Moreover, the mask main body 51 and the ear-mounting part 52 may be integrated (one connected sheet).

In the warming device 50, the minimum value Db (cm) of the width of the hanging ear portion 52 which is lower than the hole 54 becomes the direction perpendicular to the La direction from the upper end of the slit 31 to the hole 54 Its length. In other words, in a direction perpendicular to the length direction of the hole 54 of the ear-mounting portion 52, the width of the portion below the ear-mounting portion 52 becomes smaller due to the slit 31.

In the heating device 50, Da / Db is 1.3 or more and 15.0 or less. That is, since the ear-mounting portion 52 is provided with a region having a width smaller than that of the portion above the hole 54 in a direction perpendicular to the La direction, the periphery of the user's cheek to the periphery of the earlobe The area in contact with the skin becomes smaller, and when the heating ear 50 is extended to hang the heating device 50, the upper end portion of the mask body portion 51 can easily fit near the eyebrows of the wearer, and the ears 52 The lower part is prone to elongation, and it is easy to suppress the stress from being concentrated on the lower part, thereby reducing the pressure on the part or the ear behind the ear-hanging portion 52. Among them, the stress in the region from the eye tip to the earlobe can be reduced. Furthermore, since Da / Db is 15.0 or less, it is possible to maintain the strength of the ear-mounting portion (for example, it does not break from below the ear-mounting portion 52), the feeling of fitting, and reduce the pressure.
From the viewpoint of easily extending the lower part of the ear-mounting portion 52 to reduce the feeling of pressure, Da / Db is preferably 1.7 or more, more preferably 2.0 or more, and even more preferably 2.5 or more. On the other hand, from the viewpoint of obtaining a feeling of bonding, Da / Db is preferably 12 or less, more preferably 7.0 or less, and even more preferably 5.0 or less.

In the heating device 50, Da is preferably 0.5 cm or more and 4.0 cm or less. From the standpoint of maintaining the strength of the ears 52, Da is more preferably 0.8 cm or more, and further preferably 1.0 cm or more. Furthermore, it is more preferably 2.0 cm or more, and still more preferably 2.5 cm or more. On the other hand, from the viewpoint of reducing the pressure on the ear-mounting portion 52, Da is more preferably 3.5 cm or less, and further preferably 3.3 cm or less.

Further, in the warming device 50, from the viewpoint of both the improvement of the feeling of fit and the reduction of the pressure, Db is preferably 0.3 cm or more and less than 2.0 cm. From the viewpoint of maintaining the strength of the ear-mounting portion 52 and the viewpoint of improving the fitting feeling, Db is more preferably 0.5 cm or more, and still more preferably 0.6 cm or more. On the other hand, from the viewpoint of maintaining the fitting feeling of the ear-mounting portion 52 and improving the extensibility to effectively suppress the pressure, Db is more preferably 1.5 cm or less, and further preferably 1.3 cm or less.

Here, the heating device 50 of the eye mask type tends to have a significant effect on the heating effect even with a slight gap, and depending on the situation, excessive heat may be generated due to the entry of oxygen from the gap. Therefore, a higher level of fit is required. On the other hand, there is a so-called trade-off relationship between the feeling of fit and the feeling of pressure. Therefore, it is important to appropriately control the balance of the load applied to the wearer throughout the heating device 50.
In the warming device 50 in this embodiment, by satisfying the above conditions, the warming device 50 is easy to be in close contact with the eyebrows of the wearer, which can improve the fitting feeling, and can reduce the hanging ears for the wearer. The load applied to the part of the part 52 or behind the ear suppresses the feeling of pressure, so that the warming effect produced by the warming device 50 can be sufficiently obtained. In addition, with the improvement of the fit feeling, a more uniform heating effect can be obtained in the entire heating device 50. Furthermore, according to the heating device 50, a wider range is heated than before and the eyes are effectively warmed, so that a relaxed feeling of the whole body is also easily obtained.

In the above, the implementation form of this creation has been described with reference to the drawings, but these are examples of this creation, and various structures other than the above can also be adopted.
