Fig.7 (a), FIG.7 (b), FIG.7 (c) and FIG.7 (d) are typical sectional drawings of the heating tool which concerns on 2nd Embodiment.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that in all the drawings, the same components are denoted by the same reference numerals, and redundant description will be omitted as appropriate.

[First Embodiment]
First, the first embodiment will be described with reference to FIGS. 1 to 5.
The position of the cross section shown in FIG. 2 corresponds to the position of the AA line shown in FIG. However, in FIG. 2, unlike FIG. 1, the pair of ear hooks 30 are separated from the mask body 10.

  As shown in any of FIGS. 1 to 3, the heating tool 100 according to the present embodiment includes a mask body 10 that covers both eyes, a heating element 20 provided on the mask body 10, and a width direction of the mask body 10. And a pair of ear hooks 30 that are fixed to the ears and are hooked on the ears. Each of the pair of ear hooks 30 has an ear hook opening 32 for hooking the ear hook 30 on the ear. The heating tool 100 includes a distance adjustment unit that makes it possible to adjust the distance L1 (FIG. 3 and the like) between both ends of the pair of ear hooking openings 32 when the heating tool 100 is spread flat.

In the case of the present embodiment, the distance adjusting unit is configured to include a joint part 33 between the pair of ear hooks 30 and the mask main body 10, and the joint part 33 has a predetermined range R in the lateral width direction (FIG. 1, FIG. 3) and can be peeled off.
As shown in FIG. 4 or FIG. 5, the distance L <b> 1 can be increased by partially peeling the bonding portion 33 as compared to the state before peeling of the bonding portion 33 (FIG. 3). In the state of FIG. 5, compared to the state of FIG. 4, the joint portion 33 is peeled in a wider range, and the distance L <b> 1 is longer than the state of FIG. 4.
Therefore, it is possible to fit the mask body 10 appropriately around the eyes of the face by peeling an appropriate range of the joint portion 33 according to the face size of the user. That is, regardless of the face size of the user, the mask main body 10 can be appropriately fitted around the eyes of the face. Here, the eye circumference refers to the left and right eyes and an area near the circumference.

As shown in FIG. 4 or FIG. 5, the ear hooking portion 30 is lengthened by peeling the joint portion 33 to increase the distance L1 compared to the initial state shown in FIG. The force required to stretch 30 in the lateral width direction is smaller than in the state of FIG. As a result, the wearing feeling of the heating tool 100 when the heating tool 100 is worn can be further relaxed, so that a more optimal fit can be obtained for a user with a large face size.
Furthermore, as shown in FIG. 4 or FIG. 5, the vertical width of the base end portion of the ear hook 30 is reduced by peeling the joint portion 33 to increase the distance L1 compared to the initial state shown in FIG. As a result, the force required to stretch the ear hook 30 in the lateral width direction becomes smaller than that in the state of FIG. This also makes it possible to loosen the feeling of wearing the heating tool 100 when the heating tool 100 is worn, so that a more optimal fit can be obtained for a user with a large face size.

  As described above, in the heating device 100 according to the present embodiment, the distance adjustment unit adjusts the distance L1 between both ends of the pair of ear hooking openings 32, and thus the heating device 100 is required to be stretched in the lateral width direction. The magnitude of the force changes.

The mask main body 10 has, for example, a left eye covering portion 10a that covers the left eye and a right eye covering portion 10b that covers the right eye. Although the planar shape of the left eye cover part 10a and the right eye cover part 10b is not specifically limited, For example, each is formed in the substantially square shape of a rounded corner. Further, the left eye cover portion 10a and the right eye cover portion 10b are formed in substantially the same shape and size. The left eye cover portion 10a and the right eye cover portion 10b are arranged side by side in FIG.
In the present embodiment, the upper slit 14 and the lower slit 15 are formed at the boundary position between the left eye cover portion 10a and the right eye cover portion 10b. However, the present invention is not limited to this example, and the mask body 10 is The upper slit 14 and the lower slit 15 may not be provided. In this case, when the mask main body 10 is divided into right and left at the center position in the lateral width direction of the mask main body 10, the left side portion becomes the left eye cover portion 10a and the right side portion becomes the right eye cover portion 10b.

In the present specification, the horizontal width direction is a direction that coincides with the alignment direction of the left eye cover portion 10a and the right eye cover portion 10b in a state where the mask body 10 is flat as shown in FIG.
The horizontal width direction also coincides with the direction from one ear hook 30 to the other ear hook 30 in a state where the pair of ear hooks 30 are expanded to flatten the entire heating tool 100.
That is, the horizontal width direction is the left-right direction in FIG.

  Moreover, in this specification, the upper side means the direction which becomes an upper side in the state in which the upright user wore the heating tool 100, and the lower side in the state in which the upright user wore the heating tool 100. This means the lower direction. The upper side and the lower side are the upper side and the lower side in FIG.

The mask body 10 is formed in a horizontally long shape.
The mask body 10 is made of a flexible (soft) sheet material.
The mask body 10 may or may not have extensibility. The mask body 10 may or may not have elasticity.
When the mask main body 10 has extensibility or stretchability, it is preferable to have extensibility or stretchability in the lateral width direction.

More specifically, the mask body 10 includes a first sheet 11 located on the face side when the heating tool 100 is worn, and a second sheet 12 (FIG. 2) located on the opposite side to the face when worn. It is configured. Each of the first sheet 11 and the second sheet 12 may be composed of a single layer sheet, or may be a laminate of a plurality of sheets.
Examples of the material of the sheet material (the first sheet 11 and the second sheet 12) constituting the mask main body 10 include a nonwoven fabric, a woven fabric, other knitted fabrics, a resin film such as polyethylene and urethane, a porous body, and any of them. Or a combination of two or more thereof.

The first sheet 11 and the second sheet 12 are formed to have the same planar shape and dimensions, are overlapped with each other, and are joined to each other at the joint portion 13. The 1st sheet 11 and the 2nd sheet 12 may be joined by adhesion or adhesion, and may be joined by heat seal.
The joint portion 13 is disposed, for example, in the entire periphery of the peripheral edge (of the first sheet 11 and the second sheet 12) of the mask main body 10 and the range from the upper end to the lower end of the central portion in the lateral width direction of the mask main body 10. Has been. That is, the joining part 13 is arrange | positioned at the peripheral part of the left eye cover part 10a, and the peripheral part of the right eye cover part 10b.

The first sheet 11 and the second sheet 12 are not joined to each other in a region excluding the peripheral portion in the left eye cover portion 10a, that is, in the central portion of the left eye cover portion 10a. The gap between the first sheet 12 and the second sheet 12 constitutes an accommodation space 18 for accommodating the heating element 20.
Similarly, the first sheet 11 and the second sheet 12 are not joined to each other in the region excluding the peripheral edge portion in the right eye cover portion 10b, that is, in the central portion of the right eye cover portion 10b. A gap between the first sheet 11 and the second sheet 12 constitutes an accommodation space 18 for accommodating the heating element 20.
That is, the heating tool 100 includes a pair of left and right heating elements 20, one heating element 20 in the accommodation space 18 of the left eye cover 10a, and the other heating element 20 in the accommodation space 18 of the right eye cover 10b. Each is housed. Therefore, the left and right heating elements 20 are held inside the mask body 10.
When the user wears the heating tool 100, the left eye cover 10a covers the left eye, the heating element 20 in the left eye cover 10a covers the left eye, and the right eye cover 10b covers the right eye. The left and right heating elements 20 are arranged so that the heating element 20 in the right eye covering portion 10b covers the right eye.

An upper slit 14 extending downward from the upper edge of the mask main body 10 is formed at the upper edge of the central portion in the horizontal width direction of the mask main body 10. A lower slit 15 extending upward from the lower edge of the mask body 10 is formed at the lower edge of the central portion of the mask body 10 in the lateral width direction.
In the case of this embodiment, the length dimension (vertical dimension) of the lower slit 15 is larger than the length dimension (vertical dimension) of the upper slit 14. That is, the lower slit 15 is deeper than the upper slit 14.
The upper slit 14 is formed in the first sheet 11 and the second sheet 12, and the upper slit 14 of the first sheet 11 and the upper slit 14 of the second sheet 12 overlap each other in plan view.
Similarly, the lower slit 15 is formed in the first sheet 11 and the second sheet 12, and the lower slit 15 of the first sheet 11 and the lower slit 15 of the second sheet 12 are mutually in plan view. overlapping.
The upper slit 14 and the lower slit 15 are disposed at a boundary position between the left eye cover portion 10a and the right eye cover portion 10b.
In addition, the mask main body 10 may have a notch-shaped portion having a shape in which the mask main body 10 is notched instead of the upper slit 14 and the lower slit 15 above and below the central portion.

For example, as shown in FIG. 2, the heating element 20 includes a first covering sheet 21, a second covering sheet 22, and a sheet-like heat generated between the first covering sheet 21 and the second covering sheet 22. And a unit 23.
Although the planar shape of the heat generating body 20 is not specifically limited, For example, it is formed in the substantially square shape of a rounded corner.

The first cover sheet 21 and the second cover sheet 22 are formed in the same shape and size. The 1st covering sheet 21 and the 2nd covering sheet 22 are mutually overlapped so that those outlines may correspond, and those peripheral parts are joined mutually. Accordingly, the first covering sheet 21 and the second covering sheet 22 constitute a housing that houses the heat generating portion 23 therein. The first cover sheet 21 and the second cover sheet 22 may be joined by adhesion or adhesion, or by heat sealing.
The planar shape of the first cover sheet 21 and the second cover sheet 22 is formed in, for example, a substantially square shape with rounded corners.
Of the first cover sheet 21 and the second cover sheet 22, the first cover sheet 21 is disposed on the first sheet 11 side, that is, on the face side when the heating device 100 is worn. 22 is arranged on the second sheet 12 side, that is, the side opposite to the face side when worn.

The heat generating portion 23 is configured to include an oxidizable metal, and is a portion that generates heated water vapor using heat generated by an oxidation reaction caused by contact of the oxidizable metal with oxygen. . The heat generating part 23 contains an oxidizable metal, a reaction accelerator, an electrolyte, and water.
The planar shape of the heat generating part 23 is formed in, for example, a substantially square shape. The heat generating part 23 is held inside the container constituted by the first cover sheet 21 and the second cover sheet 22, that is, in the gap between the first cover sheet 21 and the second cover sheet 22.

  The heating element 20 is joined to the mask body 10 at the joint 24 shown in FIGS. 2 and 3. The joint portion 24 is disposed in a partial region of the heating element 20 in the lateral width direction. In FIG. 3, the area where the joint portion 24 is present is hatched in a plan view.

The rigidity of the heating element 20 is larger than the rigidity of the mask body 10, and the heating element 20 is less likely to deform than the mask body 10.
Here, since the joining portion 24 is arranged in a partial region in the width direction of the heating element 20, a range in which expansion and contraction of the mask main body 10 is restricted by the heating element 20 can be limited, and the joining portion 24 in the heating element 20. The other parts can be moved relative to the mask main body 10. Therefore, when the mask main body 10 has extensibility or stretchability, parts other than the joint portion 24 in the mask main body 10 can be easily stretched or stretched.

More specifically, for example, in each heating element 20, the joint portion 24 is disposed at an edge on the center side in the lateral width direction of the mask body 10.
More specifically, for example, of the outer surface of the second covering sheet 22 of the heating element 20, the edge on the center side in the lateral width direction of the mask body 10 extends from the upper end to the lower end of the edge 12. It joins with the joint part 24 with respect to the inner surface.

However, in the present invention, the joint portion 24 may be disposed over the entire surface of the heating element 20.
Further, the heating element 20 may be bonded to the inner surface of the first sheet 11 instead of the inner surface of the second sheet 12 at the bonding portion 24, or the inner surface of the first sheet 11 and the inner surface of the second sheet 12. Both may be joined at the joint 24.
Further, the inner surface of the first sheet 11 may be bonded to the heating element 20 or the second sheet 12 at the bonding portion 24 or the bonding portion 13 over the entire surface.
Similarly, the inner surface of the second sheet 12 may be bonded to the heating element 20 or the first sheet 11 at the bonding portion 24 or the bonding portion 13 over the entire surface.
That is, one surface or both surfaces of the heating element 20 may be bonded to the first sheet 1 or the second sheet 12 over the entire surface.

Here, at least one of the first cover sheet 21 and the second cover sheet 22 is made of a material having air permeability. In the case of the present embodiment, the first covering sheet 21 has higher air permeability than the second covering sheet 22. In addition, the 2nd coating sheet 22 may have air permeability, and does not need to have air permeability substantially.
The first cover sheet 21 is a moisture permeable sheet. On the other hand, the second covering sheet 22 is a moisture-permeable sheet or a moisture-impermeable sheet. When the second cover sheet 22 is a moisture permeable sheet, is the breathability of the second cover sheet 22 the same as the breathability of the first cover sheet 21 or lower than the breathability of the first cover sheet 21? The air permeability of the first cover sheet 21 is higher.

  The first sheet 11 is made of a material having air permeability and moisture permeability. The second sheet 12 may not have air permeability, or may not substantially have air permeability. Moreover, the 2nd sheet | seat 12 may have moisture permeability and may not have moisture permeability substantially.

Each of the pair of ear hooks 30 is configured by an ear hook part constituting sheet 31 that is a flexible (soft) sheet material.
The ear hook 30 has extensibility in the lateral width direction. The ear hook 30 is more preferably stretchable in the lateral width direction.
The ear hook portion constituting sheet 31 may be constituted by a single layer sheet or a laminated body of a plurality of sheets.
As the ear hook portion constituting sheet 31, a fiber sheet made of a fiber material such as a nonwoven fabric can be used.

One end of each of the pair of ear hooks 30 is bonded and fixed to both ends of the mask body 10 in the lateral width direction at the bonding portion 33. That is, one end of one ear hook 30 is fixed to one end of the left eye cover 10 a at the joint 33. Similarly, the one end part of the other ear hook part 30 is being fixed with respect to the one end part of the right eye cover part 10b in the junction part 33. FIG.
More specifically, for example, as shown in FIG. 4, the ear hooking portion 30 is fixed to the surface on the face side of the first sheet 11 by bonding at a bonding portion 33.
The joining of the ear hook 30 to the mask body 10 may be performed by heat sealing, or may be performed by adhesion or adhesion.

  In the following description, in the ear hooking portion 30, the mask body 10 side (the left eye covering portion 10a side or the right eye covering portion 10b side) is the base end (base end side), and the side far from the mask main body 10 is the tip (front end side). ). That is, the base end side portion of the ear hook 30 is fixed to the mask body 10 by the joint 33.

Although the planar shape of the ear hook 30 is not particularly limited, for example, it is formed in the same shape as the left eye cover 10a and the right eye cover 10b.
For example, as shown in FIG. 1, when the heating device 100 is folded (before being unfolded), one ear hook 30 overlaps each of the left eye cover 10 a and the right eye cover 10 b. .

As shown in FIG.1 and FIG.3, the junction part 33 is formed in the convex arc shape toward the horizontal width direction outer side. In the present embodiment, the curvature of the arc of the joint 33 is constant or substantially constant over the entire length of the joint 33.
Both end edges of the mask main body 10 in the horizontal width direction are also formed in an arc shape that protrudes outward in the horizontal width direction, and each joint portion 33 extends in an arc shape along the edge of the mask main body 10 in the horizontal width direction. doing.
In addition, in the state where the pair of ear hooks 30 overlap with the left eye cover 10a and the right eye cover 10b as shown in FIG. 1, the left edge of the left ear hook 30 in FIG. The left ear hooking portion 30 is formed so as to form a convex arc toward the right side, and the right end edge of the right ear hooking portion 30 in FIG. 1 is convex convex toward the right. The right ear hook portion 30 is formed.

In the state of FIG. 1, for example, the tips of the pair of ear hooks 30 are connected to each other. An easily breakable portion 37 extending in the vertical direction is formed at the tips of the pair of ear hooks 30. At the time of using the heating tool 100, the ear hook portion constituting sheet 31 constituting the ear hook portion 30 can be easily broken along the easy break portion 37 so that the pair of ear hook portions 30 can be separated from each other. Yes.
The easily breakable portion 37 is constituted by, for example, a half cut groove or a perforation formed in the ear hook portion constituting sheet 31 constituting the ear hook portion 30.

Each of the pair of ear hooks 30 has an ear hook opening 32 for hooking the ear hook 30 on the ear.
In the present embodiment, the ear hooking opening 32 is a through hole penetrating the front and back of the ear hooking portion 30. However, the present invention is not limited to this example, and the ear hooking opening 32 may be a slit formed in the ear hooking portion 30.
The shape of the ear hooking opening 32 is not particularly limited. For example, the ear hooking opening 32 is formed long in the width direction. Further, the vertical width dimension of the ear hook opening 32 is widened toward the tip end side of the ear hook portion 30.
The ear hooking opening 32 is disposed, for example, at the center of the ear hooking portion 30 in the vertical direction.

Each of the pair of ear hooks 30 includes a first ear hook slit 34, a second ear hook slit 35, and a third ear hook slit 36 that are continuous with the ear hook opening 32.
Of these, the first ear hook slit 34 extends downward from the lower edge of the ear hook opening 32.
The second ear-hanging slit 35 extends obliquely downward from the lower portion of the tip edge of the ear-hook opening 32 toward the tip side.
The third ear hook slit 36 extends obliquely upward from the upper end edge of the ear hook opening 32 toward the front end.
For example, the first ear hook slit 34 is longer than the second ear hook slit 35, and the third ear hook slit 36 is shorter than the second ear hook slit 35.

When the heating device 100 is used, the first ear hook slit 34, the second ear hook slit 35, and the third ear hook slit 36 are integrated with the ear hook opening 32, so that the ear hook opening Become.
For this reason, the distance L1 shown in FIGS. 1 to 3 is a distance when the ear hooking opening 32 includes the first ear hook slit 34 to the third ear hook slit 36.

In addition, the heating tool 100 is enclosed in the packaging bag (not shown) comprised with the soft packaging material in the state before use. When the heating tool 100 is taken out of the packaging bag at the time of use, the heat generating portion 23 of the heating element 20 comes into contact with oxygen in the air, and the heat generating portion 23 generates heat and generates water vapor (steam heat). The first cover sheet 21 and the first sheet 11 are discharged to the outside.
Therefore, when the user wears the heating tool 100, the water vapor is supplied to the user's face. Thereby, the user can feel comfort as if the user's face is warmed with a steam towel.
Thus, the heating tool 100 according to the present embodiment is a steam heating tool.

  When the heating tool 100 is used, the first sheet 11 of the mask body 10 is faced, the left eye cover 10a and the right eye cover 10b are respectively placed around the left and right eyes, and the pair of ear hooks 30 are respectively connected to the left and right eyes. Hook it in your ear. That is, the ear hooking openings 32 of the pair of ear hooks 30 are hooked on the left and right ears, respectively.

Since the first ear hook slit 34, the second ear hook slit 35, and the third ear hook slit 36 (see FIG. 1 and the like) are formed around the ear hook opening 32, the ear hook portion. 30 can hit the ear not by the line but by the surface, and the tactile sensation of the ear hook 30 with respect to the ear becomes softer.
In addition, since the upper slit 14 and the lower slit 15 are respectively formed in the upper edge portion and the lower edge portion of the central portion of the mask body 10 in the width direction, the heating tool 100 is easily deformed along the shape of the face. The feeling of fitting of the heating tool 100 is improved. In particular, since the lower slit 15 is formed, interference between the mask main body 10 and the nose can be suppressed.

Here, when the user wearing the heating tool 100 feels that the heating tool 100 is tight (small), for example, as shown in FIG. 4 or FIG. After expanding L1, the heating tool 100 is mounted again.
Thereby, it becomes possible to fit the mask main body 10 appropriately around the eyes of the face regardless of the face size of the user. Here, the eye circumference refers to the left and right eyes and an area near the circumference.

  When the bonding portion 33 is peeled off, the bonding portion 33 is peeled off with the end portion 33a on the center side in the lateral width direction of the mask body 10 as a starting point. For example, as shown in FIG. 3, the joint portion 33 can be peeled from the end portion 33 a side by unfolding the ear hook portion 30 and pulling the ear hook portion 30 toward the distal end side.

  Here, since the joint portion 33 has an arc shape that protrudes outward in the lateral width direction as described above, the end portion 33a is relatively easily peeled off against the force in the lateral width direction. On the other hand, in the joint portion 33, the end portion 33b on the end side in the lateral width direction of the mask body 10 is relatively difficult to peel off with respect to the force in the lateral width direction. Therefore, it is possible to easily peel the joining portion 33 partially starting from the end portion 33b while suppressing the joining portion 33 from being completely peeled off.

The heating tool 100 according to the first embodiment as described above includes a distance adjustment unit that makes it possible to adjust the distance L1 between both ends of the pair of ear hooking openings 32 when the heating tool 100 is spread flat.
Therefore, by using the distance adjusting unit to adjust the distance L1 to a length that matches the face size of the user, the mask body 10 can be appropriately fitted around the eyes of the face.
That is, regardless of the face size of the user, the mask body 10 can be appropriately fitted around the eyes of the face.

<Modification of First Embodiment>
Next, the heating tool 100 which concerns on the modification of 1st Embodiment is demonstrated using FIG.
The heating tool 100 according to this modification is different from the heating tool 100 according to the first embodiment in the shape of the joint portion 33, and is otherwise the same as the heating tool 100 according to the first embodiment. It is configured.
In the case of the present modified example, the joint portion 33 is locally bent at the outer width direction outer end portion (that is, the end portion 33b) of the joint portion 33, which is more than that in the first embodiment (FIG. 1). It has a convex arc shape.
Thereby, the adjustment width | variety of the distance between the both ends of a pair of opening 32 for ear hooks when the heating tool 100 is spread flatly is wider than 1st Embodiment.

  Each of FIG. 7A, FIG. 7B, and FIG. 7C is a schematic cross-sectional view of the heating tool 100 at the same position as FIG. However, in FIG. 7A, FIG. 7B, and FIG. 7C, only the portion in the vicinity of the proximal end portion of the ear hook 30 in the heating device 100 is shown, and the ear hook 30 is The state expanded in the width direction is shown.

  In the case of the present embodiment, as shown in FIG. 7A, the ear hooking portion constituting sheet 31 constituting each of the pair of ear hooking portions 30 is a first laminated sheet in the vicinity of the base end portion of the ear hooking portion 30. It has the laminated part 110 comprised by folding so that the two-layer sheet part of the part 111 and the 2nd laminated sheet part 112 might overlap. A folded portion 113 shown in FIG. 7A is a boundary portion between the first laminated sheet portion 111 and the second laminated sheet portion 112.

The 1st lamination sheet part 111 and the 2nd lamination sheet part 112 are mutually joined by three places, the 1st junction part 121, the 2nd junction part 122, and the 3rd junction part 123. FIG. The first joint 121, the second joint 122, and the third joint 123 are separated from each other in the lateral width direction. From the proximal end side of the ear hook 30, the first joint 121, the second joint 122, and the third joint 123 are arranged in this order.
In addition, the 3rd junction part 123 is spaced apart from the folding | returning part 113, for example.
These joint portions (the first joint portion 121, the second joint portion 122, and the third joint portion 123) can be peeled off.
In the case of this embodiment, the distance adjustment part is comprised including these junction parts (the 1st junction part 121, the 2nd junction part 122, and the 3rd junction part 123).

In other words, in the ear hook 30, a portion separated from the fixing portion (joint portion 33) of the ear hook 30 with respect to the mask body 10 is detachably bonded to the other portion of the ear hook 30, and the distance adjustment is performed. The part is configured to include this joining portion.
In addition, a plurality of parts (for example, three parts of the first joint part 121, the second joint part 122, and the third joint part 123) spaced apart in the lateral width direction of the ear-hanging part 30 with respect to the other parts in the ear-hooking part 30. Each of the distance adjusting portions is configured to include these bonding portions.

In the case of the present embodiment, as shown in FIGS. 7B to 7D, any one or more of the first joint part 121 to the third joint part 123 are peeled off to obtain FIG. The distance L2 from the base end of the ear hook 30 to the tip of the ear hook opening 32 can be increased compared to the initial state shown in FIG.
That is, FIG. 7B shows a state where the first joint 121 (FIG. 7A) is peeled off, and the second joint 122 and the third joint 123 are not peeled. The distance L2 is longer than that in the state (a).
FIG. 7C shows a state where the first joint 121 and the second joint 122 (FIG. 7A) are peeled off, and the third joint 123 is not peeled. The distance L2 is further longer than in the state of (b).
FIG. 7D shows a state in which all of the first joint 121, the second joint 122, and the third joint 123 (FIG. 7A) are peeled off, and FIG. Compared with the state of FIG.
In addition, although illustration of the whole heating tool 100 is abbreviate | omitted, in this embodiment, since distance L2 can be adjusted in this way, between the both ends of a pair of opening 32 for ear hooks when the heating tool 100 is spread flatly. Obviously, the distance L1 (see FIGS. 3 to 5) can also be adjusted.

  In the case of this embodiment, according to the face size of the user, as shown in FIGS. 7B to 7D, any one or more of the first joint part 121 to the third joint part 123 is the first. By separating the joining portion 121, the second joining portion 122, and the third joining portion 123 in this order, the distance L2 and thus the distance L1 can be adjusted, so that the mask body 10 can be appropriately fitted around the eyes of the face. It becomes possible. That is, regardless of the face size of the user, the mask main body 10 can be appropriately fitted around the eyes of the face.

In addition, as shown in FIG.7 (b)-FIG.7 (d), distance L2 is lengthened compared with the initial state shown to Fig.7 (a) by peeling the 1st junction part 121-the 3rd junction part 123. FIG. By doing so, since the ear hooking portion 30 becomes longer, the force required to stretch the ear hooking portion 30 in the lateral width direction becomes smaller than that in the state of FIG. As a result, the wearing feeling of the heating tool 100 when the heating tool 100 is worn can be further relaxed, so that a more optimal fit can be obtained for a user with a large face size.
Further, as shown in FIGS. 7B to 7D, the distance L2 is made longer than the initial state shown in FIG. 7A by peeling the first joint 121 to the third joint 123. By doing so, the length in the horizontal width direction of the laminated portion 110 having a larger elastic force than the other portion with respect to the force that stretches the ear hooking portion 30 in the horizontal width direction is shortened. This also reduces the force required to extend the ear hook 30 in the width direction compared to the state of FIG. This also makes it possible to loosen the feeling of wearing the heating tool 100 when the heating tool 100 is worn, so that a more optimal fit can be obtained for a user with a large face size.

  As described above, also in the heating device 100 according to the present embodiment, the distance adjustment unit causes the distance L2 from the proximal end of the ear hook 30 to the tip of the ear hook opening 32 (and thus the pair of ear hooks by the distance adjuster). By adjusting the distance L1 between both ends of 32 (see FIG. 3 and the like), the magnitude of the force required to stretch the heating tool 100 in the lateral width direction changes.

  In addition, in 2nd Embodiment, the heating tool 100 does not need to be provided with the adjustment function of the distance L1 using the junction part 33 which was demonstrated in 1st Embodiment. Therefore, in 2nd Embodiment, the shape of the junction part 33 is not specifically limited, It does not need to be an arc shape as shown in FIG.1 and FIG.3.

  Moreover, in 2nd Embodiment, although the site | part spaced apart from the fixing | fixed part (joining part 33) in the ear hook part 30 demonstrated the example currently joined so that peeling with respect to the other part in the ear hook part 30, In the ear hook 30, a part separated from the fixing part (joining part 33) may be detachably joined to the mask main body 10.

  Moreover, although 2nd Embodiment demonstrated the example in which the heating tool 100 has three junction parts (1st junction part 121-3rd junction part 123), a junction part should just be one or more places.

  The present invention is not limited to the above embodiment, and includes various modifications and improvements as long as the object of the present invention is achieved.

  For example, in each of the above-described embodiments, the example in which the ear hooking portion 30 has the extensibility or stretchability in the lateral width direction has been described. good.
