  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. 4 corresponds to the position of the AA line shown in FIG. However, unlike FIG. 3, the pair of ear hooks 30 are separated from the mask main body 10 in FIG. 4.

  The heating tool 100 according to the present embodiment has a mask body 10 that covers both eyes, a heating element 20 provided on the mask body 10, and one end of each of the mask body 10 that is fixed to both ends of the mask body 10 in the lateral width direction. And a pair of ear hooks 30 to be hung on the ear. The heating tool 100 includes an easily breakable portion (for example, perforation 41) extending inward from the upper edge of the heating tool 100.

Here, inward refers to the inside of the heating tool 100 from the upper edge of the heating tool 100 in a state where the pair of ear hooks 30 are deployed and the entire heating tool 100 is flattened as shown in FIG. It is the direction to go. Typically, as shown in FIG. 1, the easily breakable portion (perforation 41) extends downward from the upper edge of the heating tool 100. When the easily breakable portion extends downward from the upper edge of the heating tool 100, the easily breakable portion only needs to extend in a direction having a vertical component. Therefore, the extending direction of the easily breakable portion may be the vertical direction or may be inclined with respect to the vertical direction.
However, the present invention is not limited to this example, and the easily breakable portion may extend directly from the upper edge of the heating tool 100.

  By breaking the heating tool 100 along the easily breakable portion, it is possible to form a cut portion in the heating tool 100, thereby making it possible to easily extend the upper portion of the heating tool 100 in the lateral width direction. ing. Moreover, since the length which fractures | ruptures an easily breakable part can be adjusted arbitrarily, the extensibility of the upper part of the heating tool 100 can be adjusted by adjusting the length to fracture | rupture suitably.

  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 part 10a and the right eye cover part 10b are arranged side by side in FIGS. 1 and 2.

Here, in this 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 FIGS. is there.
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 FIGS.

  Moreover, in this specification, the upper (upper side) means the direction which becomes the upper (upper side) when the upright user wears the heating tool 100, and the lower (lower side) means the upright user. Means the direction of being down (lower side) in a state where the heating tool 100 is worn. The top and bottom are the top and bottom in FIGS.

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 preferably has extensibility, and more preferably has elasticity.
In particular, the mask body 10 preferably has extensibility in the width direction, and more preferably has elasticity in the width direction.

More specifically, the mask main body 10 includes a first sheet 11 that is located on the face side when the heating tool 100 is worn, and a second sheet 12 that is located on the opposite side of the face when worn. . 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.
The first sheet 11 and the second sheet 12 are not joined to each other in the region excluding the peripheral portion in the right eye cover portion 10b, that is, in the central portion of the right eye cover portion 10b. In the region, the first sheet The gap between the first sheet 12 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.

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.
For example, 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 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.

For example, as shown in FIG. 4, 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 bonded to the mask body 10 at the bonding portion 24 shown in FIGS. 1 and 4. The joint portion 24 is disposed in a partial region of the heating element 20 in the lateral width direction. In addition, in FIG. 1, the area | region in which the junction part 24 exists in planar view is hatched.
Here, 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 extend than the mask body 10, but the joint 24 is a partial region in the lateral width direction of the heating element 20. Is arranged. For this reason, the range in which the expansion and contraction of the mask main body 10 is restricted by the heating element 20 can be limited, and the portions other than the joint portion 24 in the heating element 20 can move 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 the edge on the center side in the 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 width direction of the mask body 10 extends from the upper end to the lower end of the edge, and the second sheet 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, and more preferably has elasticity 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 fixed to both ends of the mask body 10 in the lateral width direction at the fixing portion 33. That is, one end of one ear hook 30 is fixed to the one end of the left eye cover 10 a at the fixing portion 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 fixing | fixed 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 a fixing portion 33 by bonding.
The ear hook 30 may be fixed to the mask main body 10 by heat sealing, or by adhesion or adhesion.

Although the planar shape of the fixing portion 33 is not particularly limited, for example, the fixing portion 33 is formed in a vertically long shape (extends vertically).
In the case of the present embodiment, as shown in FIG. 1, the longitudinal axis X1 of one fixing part 33 and the longitudinal axis X2 of the other fixing part 33 extend in parallel with each other with the mask body 10 being flat. It has become.
That is, the fixing portions 33 of the pair of ear hooks 30 with respect to the mask main body 10 extend vertically and extend in parallel with each other.

  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 proximal end portion of the ear hook 30 is fixed to the mask body 10 by the fixing portion 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. 3, 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. . In this state, the outline of the left eye cover 10a and the outline of the ear hook 30 overlapping the left eye cover 10a coincide with each other in plan view, and the outline of the right eye cover 10b The outline of the ear hook 30 that overlaps the right eye cover 10b coincides with each other in plan view.

Moreover, in the state of FIG. 3, the front-end | tips of a pair of ear hook part 30 are connected, for example. A separable portion 36 that extends vertically is formed at the tip of the pair of ear hooks 30. The ear hook portion constituting sheet 31 constituting the ear hook portion 30 can be easily broken along the separable portion 36 so that the pair of ear hook portions 30 can be separated from each other.
This separable part 36 is comprised by the half cut groove | channel or perforation formed in the ear hook part structure sheet | seat 31 which comprises the ear hook part 30, for example.

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.
In the case of the present embodiment, as shown in FIG. 1, in the state where the pair of ear hooks 30 are expanded and the entire heating device 100 is flattened, the longitudinal axis X3 of one ear hook opening 32 and the other ear The longitudinal axis X4 of the hanging opening 32 extends in the lateral width direction, and the longitudinal axis X3 and the longitudinal axis X4 are located on the same straight line.

Each of the pair of ear hooks 30 includes a first ear hook slit 34 and a second ear hook slit 35 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 hook slit 35 extends from the tip edge of the ear hook opening 32 to the tip end side.
For example, the first ear hook slit 34 is longer than the second ear hook slit 35.

  As shown in FIGS. 1 and 2, the easily breakable portion (for example, perforation 41) is disposed in the vicinity of the fixing portion 33 of the ear hooking portion 30 with respect to the mask main body 10.

Here, the vicinity of the fixing portion 33 between the left eye covering portion 10a and the ear hooking portion 30 is fixed to the region closer to the fixing portion 33 than the center position in the lateral width direction of the left eye covering portion 10a or the left eye covering portion 10a. It can be set as the area | region near the said fixing | fixed part 33 rather than the center position in the horizontal width direction of the ear hook part 30. FIG.
Similarly, the vicinity of the fixing portion 33 between the right eye covering portion 10b and the ear hooking portion 30 is fixed to the region closer to the fixing portion 33 than the center position in the lateral width direction of the right eye covering portion 10b or to the right eye covering portion 10b. It can be set as the area | region near the said fixing | fixed part 33 rather than the center position in the horizontal width direction of the ear hook part 30. FIG.

In the present embodiment, the easily breakable portion (perforation 41) is formed in the ear hook portion 30.
That is, the perforation 41 extends inward from the upper edge of the ear hook 30 at a portion of the ear hook 30 near the fixing portion 33.
The position of the lower end of the perforation 41 is not particularly limited, but is preferably a position above the lower edge of the ear hook 30. That is, it is preferable that the ear hook 30 is not divided even if the ear hook 30 is broken along the perforation 41 from the upper edge of the ear hook 30 to the end of the perforation 41.
The perforation 41 is separated from the ear hooking opening 32 and is not connected to the ear hooking opening 32. Thereby, even if the ear hook 30 is broken to the end of the perforation 41, the perforation 41 and the ear hooking opening 32 are not connected.
The height position (position in the vertical direction) of the perforation 41 may be above the ear hooking opening 32 as shown in FIG. 1 or may be below the ear hooking opening 32. It may be between the upper end and the lower end of the ear hooking opening 32.

  The user can easily break the ear hanger 30 along the perforation 41 by pinching the ear hanger 30 with both left and right hands and tearing the ear hanger 30 in the ear hanger 30. It is like that.

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. As a result, 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.

As shown in FIG. 5, when the heating device 100 is used, the first sheet 11 of the mask body 10 faces the face side, the left eye cover portion 10a and the right eye cover portion 10b are respectively placed around the left and right eyes 52, and a pair of The ear hooks 30 are hooked on the left and right ears 54, respectively.
At this time, by cutting the ear hook 30 in advance along the perforation 41 by an appropriate length according to the user's face size, the portion that was the perforation 41 as shown in FIG. It becomes a shape and the ear hook part 30 can extend easily. Thereby, the mask main body 10 can be fit moderately around the eyes of the face 51. Here, the circumference of the eyes are the left and right eyes 52 and a region in the vicinity thereof.
Further, when the user feels that the heating tool 100 is tight after wearing the heating tool 100 once, the mask body 10 is made to face 51 by breaking the ear hook 30 deeper along the perforation 41. It can be fit moderately around the eyes.
Of course, when the user's face size is small, the perforation 41 need not be broken. Further, the perforations 41 may be broken equally for the left and right ear hooks 30, or the left and right perforations 41 may be made different in length for adjusting the fit.

Further, since the perforation 41 is disposed in the vicinity of the fixing portion 33, the ear hooking portion 30 can be easily deformed in the vicinity of the fixing portion 33. Therefore, the longitudinal axis X3 of one of the ear hooking openings 32 can be inclined downward toward the tip of the ear hooking portion 30 while maintaining the axis X5 extending in the lateral width direction of the mask body 10 substantially horizontal. Although not shown in FIG. 5, the longitudinal axis X4 (see FIG. 1) of the other ear hooking opening 32 can also be inclined downward toward the tip of the ear hooking portion 30.
Thereby, it is possible to achieve both good fit of the mask body 10 around the eyes of the face 51 and reduction of the load acting on the ear 54 from the ear hook 30.

Since the first ear hook slit 34 and the second ear hook slit 35 (see FIG. 1 and the like) are formed around the ear hook opening 32, the ear hook portion 30 is not a line but an ear. You can hit 54. Therefore, the tactile sensation of the ear hook 30 with respect to the ear 54 becomes softer.
In addition, since the upper slit 14 and the lower slit 15 are formed in the upper edge portion and the lower edge portion of the central portion of the mask body 10 in the lateral width direction, the heating tool 100 is deformed along the shape of the face 51. It is easy to improve the fit of the heating tool 100. In particular, since the lower slit 15 is formed, interference between the mask main body 10 and the nose 53 can be suppressed.

  According to the heating tool 100 according to the first embodiment as described above, since the easily breakable portion (for example, perforation 41) extending inward from the upper edge of the heating tool 100 is provided, the face size of the user Regardless of this, the mask main body 10 can be appropriately fitted around the eyes of the face.

  Further, since the perforation 41 as the easily breakable portion is disposed in the vicinity of the fixed portion 33, as shown in FIG. 5, the longitudinal axes X3 and X4 of the ear hooking opening 32 are set while the axis X5 is substantially horizontal. It is easy to incline with respect to the axis X5.

Here, when the mask main body 10 and the ear hook 30 are made of materials that are difficult to be bonded to each other by heat sealing, for example, an adhesive or an adhesive is applied to the mask main body 10 and the mask main body 10 and the ear hook are attached. The part 30 can be joined to each other by the fixing part 33. In this case, it is easier to apply the adhesive or the adhesive to the mask body 10 when the pair of fixing portions 33 extend in parallel to each other as in the present embodiment.
On the other hand, when the fixing portions 33 are parallel to each other, the inclination angle of the longitudinal axis X3 with respect to the axis line X5 and the inclination angle of the longitudinal axis X4 with respect to the axis line X5 as shown in FIG. On the other hand, the heating tool 100 according to the present embodiment includes an easily breakable portion (for example, perforation 41) extending inward from the upper edge of the heating tool 100. Therefore, even when the pair of fixing portions 33 extend in parallel with each other by breaking the easily breakable portion, the inclination angle of the longitudinal axis X3 with respect to the axis X5 as shown in FIG. The inclination angle of the longitudinal axis X4 with respect to the axis X5 can be easily generated. That is, both the ease of manufacturing the heating tool 100 and ensuring or improving the fit of the mask body 10 can be achieved.

<Variation 1 of the first embodiment>
Next, Modification 1 of the first embodiment will be described with reference to FIG.
The heating tool 100 according to the present modification is different from the heating tool 100 according to the first embodiment in the points described below, and is otherwise similar to the heating tool 100 according to the first embodiment. It is configured.

In the case of this modification, the heating tool 100 has a second perforation 42 as a second easily breakable portion that extends upward from the lower edge of the ear hook 30. The second perforation 42 is disposed in the vicinity of the fixed portion 33. More specifically, the second perforation 42 is disposed on the extension of the perforation 41.
The length dimension of the second perforation 42 is not particularly limited, but is preferably shorter than the perforation 41.

  In the case of this modification, for example, the perforation 41 and the second perforation 42 are each broken so that the break length of the perforation 41 is longer than the break length of the second perforation 42 (the second perforation 42 is The heating tool 100 can be worn, including the case where it does not break.

  According to this modification, the same effect as in the first embodiment can be obtained, and only the upper edge portion can be obtained by breaking the second perforation 42 at the lower edge portion of the ear hook portion 30 as necessary. In addition, since the extensibility of the lower edge portion can be adjusted, the mask body 10 can be more appropriately fitted around the eyes.
