First, the heating device 100 of this embodiment is demonstrated using FIGS. 1-5.

Fig. 1 shows that the body part 10 of the heating appliance 100 and a pair of hanging ear parts 30 on the left and right are flatly developed. open state. In FIG. 1 , in the heating device 100 , the surface that becomes the face side in the state where the heating device 100 is worn on the user's face is shown.

FIG. 2 shows a state in which the heating device 100 is folded in half at the central part of the main body 10 in the width direction (after the heating device 100 is folded in two) with the surface that becomes the face side in the wearing state as the inside. That is, in FIG. 2 , the following first part 11 and second part 12 of the main body part 10 overlap each other, and the state where the left ear hanging part 30 and the right ear hanging part 30 overlap each other is shown. Moreover, in FIG. 2, in the 1st part 11 of the main body part 10 of the heating device 100, the surface which faces outward in the state which wore the heating device 100 on the user's face is shown.

Fig. 3 shows the cross-section obtained by cutting the heating device 100 along the width direction consistent with the arrangement direction of the first part 11 and the second part 12 in the state where the heating device 100 is unfolded (along Fig. 1 In the diagram of the cross-section of line A-A of ), when the heating device 100 is worn on the user's face, the surface facing the face side is shown on the upper side, and the surface facing the outside is shown on the lower side.

In this embodiment, when there is no special description, the description of the positional relationship (upper and lower relationship, etc.) of the components of the heating device 100 is for wearing the heating device 100 on the top of the head as shown in FIG. 4 In addition, the positional relationship in the state of the user's face in the posture where the neck is positioned downward will be described.

As shown in any one of Fig. 1 to Fig. 4, the heating device 100 of the present embodiment is provided with: a main body portion 10, which is worn along the face; a heating element 20, which is arranged on the main body portion 10; and a pair of ear hanging portions 30, which are respectively provided at both ends of the main body 10 in the width direction.

Each of a pair of ear-hanging part 30 has the opening 30a for hanging ears. The opening 30a for hanging ears is preferably extended along the side edge of the main body part 10 (formed to be long in the longitudinal direction of the side edge of the main body part 10 the lengthwise shape). In the case of this embodiment, the opening 30a for hanging ears is the folded line slit 31 for hanging ears which does not have width substantially.

The pair of ear hanging parts 30 are respectively hung on the ears, and the user can wear the heating device 100 by hanging the ear hanging parts 30 on the ears.

The ear hanging portion 30 may be formed from a sheet material integrated with the main body portion 10 , or may be provided by joining a material different from the main body portion 10 to the main body portion 10 .

As shown in FIG. 1 , when the body portion 10 and the pair of ear-mounting portions 30 are flatly expanded, the distance between the pair of ear-hanging portions 30 is set to W and the longitudinal dimension of the ear-hanging opening 30a is set to W. When it is H, H/W is 0.2 or more.

Here, the state where the body part 10 and the pair of ear parts 30 are spread out flatly refers to the state where the whole heating device 100 is spread out as flat as possible and the whole heating device 100 is naturally placed ( However, when the heating device 100 is equipped with the three-dimensional structure part 60 described below without applying tension to extend the heating device 100 around, it is a state in which the overall strain of the three-dimensional structure part 60 is equalized).

The distance W is, for example, the distance between a pair of ear parts 30 at the same height as the center 20c in the vertical direction of the heating element 20 when the entire heating device 100 is spread out as flat as possible. As shown in Figure 1, the distance between a pair of hanging ear parts 30 is at the same height as the center 20c in the upper and lower direction of the heating element 20, and the distance between the edges of the opening 30a on the side away from the main body part 10 for a pair of hanging ears Distance (see also Fig. 7(a), Fig. 7(b) and Fig. 8 described below as variant examples).

The longitudinal dimension H of the opening 30a for the hanging ear is the dimension of the opening 30a for the hanging ear in the direction perpendicular to the arrangement direction of the pair of hanging ear parts 30 (the distance W direction in FIG. 1 ), that is, the dimension of the opening 30a for the hanging ear. The height difference between the upper end and the lower end (between the lower end of the lower part 31a of the slit for hanging ears and the upper part 31b of the slit for hanging ears height difference at the top).

The heating device 100 of the present invention has a structure in which the vertical dimension H of the opening 30 a for the ear is larger than the distance W between the pair of ear parts 30 , and is greater than a certain level. Thereby, when the heating device 100 is worn, the side edge portion (bending portion 81 shown in FIG. 4 ) of the main body portion 10 can be convexly bent forward, so that the main body portion 10 can be aligned from the side of the main body portion 10. Smooth introduction of external air between the face and the face can make the heating element 20 generate heat more uniformly. Furthermore, the reason for forming the curved portion 81 is that the face of a person is in a shape that protrudes forward, and the ears are located behind the eyes or the cheeks.

More specifically, the bent portion 81 is bent so as to satisfy the following conditions (1) and (2), for example.

(1) "The upper end and lower end of the part of the ear-hanging part 30 closer to the main body 10 side than the ear-hanging opening 30a (the ear-hanging slit 31 in FIG. 1 ) and along the part of the ear-hanging opening 30a ", or "the upper end and the lower end of the side edge of the main body 10 along the ear-hanging opening 30a" are relatively rearward, and are arranged near the front side of the cheek adjacent to the ear.

(2) "The part of the ear-hanging part 30 that is closer to the main body 10 side than the ear-hanging opening 30a and the middle part in the vertical direction along the position of the ear-hanging opening 30a", or "the side edge of the main body 10 The middle portion along the upper and lower direction of the ear-hanging opening 30a is located relatively forward, and is arranged at a position in the cheek away from the position adjacent to the front side of the ear toward the side.

Furthermore, H/W is preferably 0.25 or more, and by doing so, the bending portion 81 can be bent more reliably. Also, H/W is preferably at most 0.7, more preferably at most 0.6.

Also, when the side away from the main body part 10 and the side connecting the upper end and the lower end of the opening 30a for hanging ears are When the circumference is L, H/L is preferably 0.6 or more, and by doing so, the bending portion 81 can be bent more reliably. In the case of this embodiment, the circumference L becomes the sum of the length L11 and the length L12 shown in FIG. 1 .

When the ear opening 30a does not substantially have the wide ear slit 31 as in this embodiment, the perimeter of the ear opening 30a on the side away from the main body 10 can be set as the ear slit. The total extended length of the slit 31 is the sum of the length dimension of the lower slit 31a for the ear and the length of the upper slit 31b for the ear.

H/L is more preferably 0.8 or more. Moreover, H/L is 1 or less.

In the case of this embodiment, the main body part 10 has a sheet shape (planar shape) having a three-dimensional structure part 60 described below, and is formed in a size that can cover the parts of the face from the eyes to the cheeks.

Here, the body part 10 covering the eye means covering the front (front side) of the entire eye socket (around the eye). In addition, the body part 10 covering the cheek means covering at least the front (front side) of the lower end position of the cheekbone. That is, the part of the body part 10 covering the face from the eyes to the cheeks refers to the area covering the front of the range from the upper part around the eyes to the lower part of the cheekbones.

Since the main body 10 is formed in such a size as to cover the above-mentioned parts, the heating element 20 disposed on the main body 10 can warm the face covered by the main body 10 in a wide range.

In the case of this embodiment, a slit 54 extending upward from the lower edge of the main body part 10 is formed in the central part in the width direction of the main body part 10 . Furthermore, the slit 54 is not limited to a linear (linear, etc.) slit, and may be a notch-shaped portion in an inverted V-shape or an inverted U-shape. In the case of the present embodiment, the slit 54 is a linear slit in the folded state shown in FIG. 2 , but is opened in an inverted V shape in the unfolded state shown in FIG. 1 .

A slit 54 extending upward from the lower edge of the main body 10 is formed at the central part in the width direction of the main body 10, whereby external air can be smoothly introduced from the bottom of the main body 10 to the bottom and the bottom of the main body 10. Between the faces, and the external air can be supplied to the heating element 20 to make the heating element 20 generate heat.

In the case of this embodiment, the upper edge of the main body portion 10 extends substantially horizontally, or slightly rises and slopes toward the central portion (forming an upwardly protruding mountain shape). A three-dimensional structure portion 60 having a curved shape in which the upper portion protrudes forward is formed (details will be described later).

Therefore, it is easy to make the upper edge of the central part in the width direction of the main body part 10 close or close to the forehead, and it is possible to suppress warm air from escaping upward from the gap and fill the three-dimensional structure part 60 with warm air. Thereby, the face covered by the main body part 10 can be warmed sufficiently in a wide range.

In this way, according to the warming device 100 , the face can be warmed in a wide range by the heating element 20 in a state where the body part 10 covers the parts from the eyes to the cheeks of the face. In addition, outside air can be smoothly introduced from the bent portion 81 along the ear opening 30a, and outside air can also be smoothly introduced from below the main body 10, so that the entire heating element 20 can generate heat. Thus, a large area of the face can be warmed more sufficiently.

Since the heating device 100 has the three-dimensional structure part 60, when the heating device 100 is worn, a convex shape is formed on the upper part of the central part in the width direction of the main body part 10, and the side edge part of the main body part 10 is also easy to bend. Therefore, the side edge portion (bending portion 81 shown in FIG. 4 ) of the main body portion 10 can be more easily curved forwardly. Therefore, the external air can be introduced more smoothly from the side of the main body 10. Between the body part 10 and the face, the entire heating element 20 can generate heat more uniformly.

In the case of this embodiment, as described below, the heating device 100 is a steam heating device. Therefore, similar to the case of the above-mentioned air, it is possible to prevent steam from escaping from the gap between the upper edge of the central part in the width direction of the main body 10 and the face, and the steam can be filled between the main body 10 and the face.

The main body 10 is formed in a size and shape that can cover both eyes and both cheeks.

The main body portion 10 is configured to include a first portion 11 covering the area from the left eye to the left cheek, and a second portion 12 covering the area from the right eye to the right cheek.

The first part 11 and the second part 12 are formed in substantially the same shape and size as each other. In FIG. 1 , the first part 11 and the second part 12 are arranged side by side, and are separated from each other by a slit 54 at the lower part of the main body part 10 .

The planar shape of the main body portion 10 is not particularly limited, and for example, as shown in FIG. 1 , it may be a substantially rectangular shape that is slightly horizontally long. Furthermore, since the slit 54 is formed in the main body part 10 , an inverted V-shaped or inverted U-shaped cutout is formed at the lower part of the central part in the lateral direction of the main body part 10 .

Also, the planar shape of the first part 11 and the second part 12 can be, for example, a substantially quadrangular shape slightly larger than the heating element 20 (for example, a slightly elongated quadrangular shape).

In the case of this embodiment, the main body portion 10 preferably does not have a slit extending downward from the upper edge of the main body portion 10 (including the notch-shaped portion). With such a configuration, the upper edge of the main body 10 can be continuously in close contact with the user's forehead in the width direction, and warm air or steam can be filled between the main body 10 and the face.

Also, in FIG. 1 , the upper edge of the body portion 10 is slightly raised and inclined toward the central portion (formed into a mountain shape protruding upward), but in the state where the heating device 100 is folded in half as shown in FIG. 2 , for example, the body portion The upper edge of 10 slopes downward toward the side edge of the main body portion 10 .

In the case of the present embodiment, for example, the lower edge of the main body portion 10 extends substantially horizontally except for the portion where the slit 54 is formed. Moreover, in the state where the heating device 100 is folded in half as shown in FIG. 2 , for example, the lower edge of the main body 10 is inclined downward toward the side edge of the main body 10 .

The dimension of the body part 10 in the up and down direction perpendicular to the width direction is set such that the body part 10 can cover from the part slightly above the upper edge of the brow peak to the part slightly below the corner of the mouth.

Also, the side edge of the main body 10 covers, for example, from the temple to the vicinity of the rear end of the cheek (the part of the cheek adjacent to the front side of the ear).

Also, in the first portion 11 and the second portion 12, the portion along the slit 54 extends from the nose side along the nasolabial folds, for example.

The lower ends of the first part 11 and the second part 12 are located lower than the lower lip, for example.

In more detail, for example, the portion along the slit 54 in the heating element 20 (the inner edge 25 shown in FIGS. The lower end covers the corners of the mouth.

The three-dimensional structure part 60 covers, for example, the portion from the lower end of the central part in the width direction of the forehead to the upper end of the bridge of the nose (nose root). In the case of the present embodiment, the three-dimensional structure portion 60 is configured to include a part of the upper edge of the main body portion 10 . However, the present invention is not limited to this example, and the three-dimensional structure part 60 may not include the upper edge of the main body part 10 (it may also be arranged at a position lower than the upper edge of the main body part 10).

In the case of the present embodiment, the heating device 100 is configured to include a first sheet 51 and a second sheet 52 arranged to overlap the first sheet 51 .

Each of the first sheet 51 and the second sheet 52 may consist of a single-layer sheet, or may be a laminate of plural-layer sheets.

Each of the first sheet 51 and the second sheet 52 includes a flexible material. Examples of materials for the first sheet 51 and the second sheet 52 include nonwoven fabrics, woven fabrics, other knitted fabrics, resin films such as polyethylene or urethane, porous bodies, and any two of them. Combinations of the above, etc.

The first sheet 51 is formed, for example, in the shape of the main body 10 .

On the other hand, the second sheet 52 is formed in the same shape as the overall shape of the heating tool 100 . More specifically, as shown in FIG. 1 , the left end and the right end of the second sheet 52 protrude from the first sheet 51 respectively, and the protruding portions constitute the left and right ear hanging portions 30 . When the heating device 100 is worn, the first sheet 51 is located on the face side, and the second sheet 52 is located on the opposite side to the face (that is, facing outward).

As shown in FIG. 3 , the opposing surfaces of the first sheet 51 and the second sheet 52 are joined to each other at the joining portion 53 .

The first sheet 51 and the second sheet 52 may be joined by adhesion or adhesion, or may be joined by heat sealing. In the case of this embodiment, the junction part 53 is comprised by heat fusion, for example.

The joint part 53 is arranged, for example, over the entire periphery of the peripheral part of the main body part 10 and in the range from the upper edge to the lower edge of the central part in the width direction of the main body part 10 . More specifically, the joining portion 53 is arranged, for example, over the entire circumference of the peripheral portion of the first portion 11 and the entire circumference of the peripheral portion of the second portion 12 .

In addition, the joining part 53 joins not only the 1st sheet 51 and the 2nd sheet 52, but also joins the 1st sheet 51 or the 2nd sheet 52, and the heat generating body 20, for example.

The heating element 20 is provided between the first sheet 51 and the second sheet 52 .

More specifically, the heating element 20 is provided between the first sheet 51 and the second sheet 52 in each of the first part 11 and the second part 12 .

In the case of the present embodiment, the disposition area of the heating element 20 is set to a size that covers the range from the eyes to the lower part of the cheek than the corner of the mouth.

Thereby, it is possible to more fully warm a large area of the face from the eyes to the cheeks (the part of the cheeks that is lower than the corners of the mouth).

More specifically, the heating element 20 installed in the first part 11 is set to cover the range from the left eye to the lower part of the left cheek than the corner of the left mouth, and the heating element 20 installed in the second part 12 The size that is set to cover the area from the right eye to the part of the right cheek that is lower than the corner of the right mouth.

Moreover, the heating element 20 provided on the first part 11 is set to cover the left temple, and the heating element 20 provided on the second part 12 is set to cover the right temple.

Here, in the first part 11, a single heating element may be provided, or a heating element group which is an aggregate of a plurality of heating elements arranged adjacent to or close to each other may be installed.

Similarly, in the second part 12, a single heating element may be provided, or a heating element group which is an aggregate of a plurality of heating elements arranged adjacent to each other or close to the ground may be installed.

The heating element 20 refers to the single heating element mentioned here, or the heating element group. Therefore, the arrangement area of the so-called heating element 20 can be set as the arrangement area of a single heating element, or the arrangement area of the heating element group. setting area.

The planar shape of the disposition area of the heating element 20 in the first part 11 and the second part 12 is not particularly limited. In the case of this embodiment, for example, the disposition area of each heating element 20 is formed in a rectangular shape (for example, a square shape).

As shown in FIG. 1 , the upper edge of the disposition area of the heating element 20 is, for example, inclined upward toward the side edge of the main body portion 10 . Therefore, the upper and lower dimensions of the area between the upper edge of the disposition area of the heating element 20 and the upper edge of the main body 10 (that is, the area on the upper side of the heating element 20 where the heating element 20 does not exist) are, for example, toward the width of the main body 10. The center of the direction gradually expands (towards the side edge of the main body portion 10, it gradually decreases). Thereby, the upper part of the central part in the width direction of the main body part 10 becomes a curved shape protruding forward, and it is easy to wear the upper edge of the heating device 100 closely or close to the forehead.

In addition, the portion along the slit 54 in the heating element 20 (the inner edge 25 shown in FIGS. 1 and 4 ) extends parallel to the slit 54 , for example. The inner edge 25 is arranged close to the slit 54, for example.

On the other hand, in the heating element 20, the edge portion (the outer edge 26 shown in FIG. 1 ) on the opposite side to the inner edge 25 extends, for example, along the side edge 51a ( FIG. 1 ) of the first sheet 51 (for example, for the side side 51a extends in parallel). The outer edge 26 is arranged close to the ground with respect to the side 51a, for example.

As shown in FIG. 3 , the heat generating body 20 is configured, for example, as a sheet-shaped sheet including a first covering sheet 21, a second covering sheet 22, and a thin sheet held between the first covering sheet 21 and the second covering sheet 22. Heating material 23.

The first covering sheet 21 and the second covering sheet 22 are, for example, formed in the same shape and size as each other. inch. In addition, they overlap each other so that their outer contour lines are consistent, and their peripheral edge portions are joined to each other. Thereby, the container which accommodates the heating material 23 inside is comprised. The joining of the first covering sheet 21 and the second covering sheet 22 may be completed by adhesion or bonding, or may be completed by heat sealing.

The planar shapes of the first covering sheet 21 and the second covering sheet 22 are not particularly limited, and in the case of the present embodiment, the first covering sheet 21 and the second covering sheet 22 are respectively formed in a rectangular shape (for example, square shape).

The first covering sheet 21 is disposed on the first sheet 51 side, that is, the side that becomes the face side when the heating device 100 is worn, and the second covering sheet 22 is disposed on the second sheet 52 side, that is, the side that becomes the face side when the heating device 100 is worn. It becomes the side opposite to the face side (front side).

The heat generating material 23 is composed of a metal to be oxidized. The heating material 23 generates heat by the oxidation reaction caused by the contact between the oxidized metal and oxygen. Also, in the case of the present embodiment, the heating material 23 is configured to generate heated water vapor by utilizing the heat generated in the oxidation reaction caused by the contact between the oxidized metal and the acid.

The heat generating material 23 contains, for example, a metal to be oxidized, a reaction accelerator, an electrolyte, and water.

The heat generating material 23 is formed in a sheet shape, for example.

In one container including the first covering sheet 21 and the second covering sheet 22, one heating material 23 may be accommodated, or a plurality of heating materials 23 may be accommodated.

In addition, the above-mentioned "individual heating element" is configured to include one housing and one or a plurality of heating materials 23 accommodated in the one housing.

On the other hand, the above-mentioned "heat-generating body group" is obtained by combining a plurality of such "separate The "heating elements" are arranged adjacent to each other or close to the ground.

For example, one or a plurality of heat generating materials 23 are arranged in a rectangular (for example, square) region smaller than the first covering sheet 21 and the second covering sheet 22 .

In addition, the heat generating material 23 is preferably bonded to at least one of the first covering sheet 21 or the second covering sheet 22 .

In addition, the joining portion 53 joins the peripheral portion of the heating element 20 and at least one of the first sheet 51 or the second sheet 52 to each other. That is, the joining part 53 joins the 1st covering sheet 21 and the 1st sheet 51 mutually, or joins the 2nd covering sheet 22 and the 2nd sheet 52 mutually. In the case of this embodiment, for example, as shown in FIG. 3 , the joining portion 53 joins the first covering sheet 21 and the first sheet 51 to each other, and joins the second covering sheet 22 and the second sheet 52 to each other. join.

In this way, the heat generating elements 20 on the left and right are respectively held inside the first part 11 and the second part 12 .

Moreover, in the central part (except the peripheral portion) of the heating element 20, for example, the heating element 20 and the first sheet 51 are not joined to each other, and the heating element 20 and the second sheet 52 are not joined to each other (refer to image 3).

At least one of the first covering sheet 21 and the second covering sheet 22 of the heating element 20 has air permeability.

In the case of this embodiment, the first covering sheet 21 has air permeability. Also, the first covering sheet 21 has higher air permeability than the second covering sheet 22 . In addition, the 2nd covering sheet 22 may have air permeability, and may not have air permeability substantially.

Furthermore, the first covering sheet 21 has air permeability so as to allow air and water vapor to pass therethrough. On the other hand, the second covering sheet 22 is less air-permeable or impermeable than the first covering sheet 21 .

The air permeability of the first covering sheet 21 is preferably at least 1000 seconds/100ml, and more preferably at least 2000 seconds/100ml, in order to more sufficiently warm a wide area of the face. Moreover, it is preferably 50000 seconds/100ml or less, more preferably 20000 seconds/100ml or less, still more preferably 10000 seconds/100ml or less.

Air permeability is a value measured according to JIS (Japanese Industrial Standards) P8117, and is defined by the time for 100ml of air to pass through an area of 6.45cm ² under a fixed pressure. The air permeability can be measured by Wangyan air permeability meter or a measuring machine based on it.

As such an air-permeable sheet, a resin-made porous sheet having moisture-permeability but not water-permeability or a resin-made sheet having air holes can be used, for example, polyethylene, polypropylene, ethylene, etc. can be used. - vinyl acetate copolymers and the like.

As the porous resin sheet, one obtained by molding a melt-kneaded thermoplastic resin and an organic or inorganic filler incompatible with the resin into a film and stretching it uniaxially or biaxially can be used. In addition, a non-air-permeable sheet or an air-impermeable sheet provided with fine holes by needles or the like, or a sheet further provided with fine holes by needles or the like can be used. The thickness of the air-permeable sheet is preferably not less than 5 μm and not more than 200 μm.

On the other hand, the second covering sheet 22 may be an air-permeable sheet or an air-impermeable sheet. When the second covering sheet 22 is an air-permeable sheet, the air permeability is preferably 80000 seconds/100ml or more. In the case where the second covering sheet 22 is an air-impermeable sheet, as As the air-impermeable sheet, a laminated sheet obtained by laminating an air-impermeable resin film and paper or the like can be used.

The first covering sheet 21 and the second covering sheet 22 may each include a single thin sheet, or may include a laminate of a plurality of thin sheets. As such a laminate, a laminated sheet obtained by laminating a nonwoven fabric and an air-permeable sheet, or a laminated sheet obtained by laminating a knitted fabric and an air-permeable sheet can be used.

In the case of this embodiment, as described above, the heat generating material 23 generates water vapor by heat generation, and the first covering sheet 21 has moisture permeability, and the first sheet 51 has moisture permeability. Therefore, water vapor can be released through the face side of the body part 10, and the water vapor can be brought into contact with the face.

That is, the heat generating material 23 generates water vapor when it generates heat, and the heating device 100 is configured such that the water vapor is released to the outside through the surface of the main body 10 that is on the face side.

The shape of the ear hanging portion 30 is not particularly limited, but in the case of the present embodiment, the ear hanging portion 30 is formed in a vertically long shape (a vertically long shape).

The upper and lower dimensions of the ear hanging portion 30 are set to be equal to the upper and lower dimensions of the main body portion 10 , for example.

Since the hanging ear part 30 is vertically long, the upper end and the lower end of the side edge of the main body part 10 can be respectively pulled backward by the hanging ear part 30, so that the bending part 81 can be fully bent.

In the case of this embodiment, the ear hanging portion 30 has a vertically long ear hanging slit 31 as an ear hanging opening 30a. When wearing the warming device 100, as shown in FIG. 4, the body part 10 is closely attached to the part of the face from the eyes 75 to the cheeks 76, and the left and right ear parts 74 are inserted into the hanging parts of the left and right ear parts 30. Behind the ear slit 31 , hang the ear hanging part 30 behind the ear part 74 .

More specifically, the height position of the lower end of the slit 31 for hanging ears is set to be substantially the same height position as the lower end of the heating element 20 , for example. On the other hand, the height position of the upper end of the slit 31 for hanging ears is, for example, set at a lower position than the upper end of the heating element 20, and is set at the center 20c of the heating element 20 in the vertical direction (Fig. 1, Fig. 1 ). Figure 2) The position is closer to the top.

That is, the slits 31 for hanging ears are arranged slightly lower than the heating element 20 . With such an arrangement of the slits 31 for hanging ears, when the heating device 100 is worn, the slits 54 can be largely opened in an inverted V-shape or an inverted U-shape, and the three-dimensional structure can be sufficiently ensured. The size of the gap between 60 and the face. Furthermore, since the upper part of the main body part 10 can be pulled back more strongly, the bending part 81 can be fully bent.

The part between the upper end of the ear slit 31 and the upper edge of the ear part 30 becomes the upper side connection part 32 of the ear, which connects the side of the ear part 30 closer to the main body 10 than the slit 31 for the ear The part and the part on the side farther from the main body 10 than the slit 31 for the ear are connected on the upper side of the slit 31 for the ear.

Similarly, the part between the lower end of the ear-mounting slit 31 and the lower edge of the ear-mounting portion 30 becomes the lower side connecting portion 33 of the ear-mounting ear, which connects the ear-mounting portion 30 closer to the body than the ear-mounting slit 31 The part on the side of the part 10 and the part on the side farther from the main body part 10 than the slit 31 for the ear are connected at the lower side of the slit 31 for the ear.

In the case of this embodiment, the upper and lower width dimension L1 ( FIGS. 1 and 2 ) of the upper ear connection portion 32 is set larger than the upper and lower width dimension L2 ( FIGS. 1 and 2 ) of the lower ear connection portion 33 . In other words, the distance between the upper edge of the ear part 30 and the upper end of the slit 31 for the ear is greater than the distance between the lower end of the slit 31 for the ear and the lower edge of the ear part 30 .

Thereby, the stretching of the upper connecting portion 32 of the ear hanging can be suppressed when the heating device 100 is worn, and when the ear hanging 30 is hung on the ear, the side edge of the main body 10 can be held by the ear hanging 30. The upper part is drawn more fully towards the rear. Thus, as shown in FIG. 4 , the bending portion 81 can be sufficiently bent, and the portion of the main body 10 that is closer to the center in the width direction than the bending portion 81 can be satisfactorily conformed to the face.

On the other hand, since the lower connecting portion 33 of the hanging ear can be stretched moderately, the ear hanging portion 30 can fit well on the ear regardless of the size of the user's ear.

Here, the upper and lower width dimension L1 can be set, for example, as the distance between the upper edge of the ear part 30 and the slit 31 on the straight line AX1 ( FIGS. 1 and 2 ) connecting the upper end and the lower end of the slit 31 for the ear. distance from the top.

Also, the vertical width dimension L2 can be set as the distance between the lower edge of the ear part 30 and the lower end of the slit 31 for the ear on the straight line AX1 (Fig. 1, Fig. 2).

The slits 31 for hanging ears are, for example, protruding and curved in a direction away from the main body 10 in the widthwise direction. That is, in the unfolded state shown in FIG. 1 , the slit 31 for the hanging ear on the left side protrudes and bends toward the left, and the slit 31 for the hanging ear on the right side protrudes and bends toward the right.

More specifically, in the case of the present embodiment, the slit 31 for the lug is formed, for example, in a folded line shape that is convexly bent in a direction away from the main body portion 10 in the widthwise direction.

For example, the slit 31 for the ear is configured to include the straight slit lower part 31a for the ear which constitutes the lower part of the slit 31 for the ear and the straight slit for the ear which constitutes the upper part of the slit 31 for the ear. upper part 31b.

Furthermore, the interface between the lower slit 31a for the ear and the upper slit 31b for the ear is the slit for the ear. The bending part 31c of the slit 31 is arrange|positioned below the center position (31d of the slit center 31d for hangers) in the up-down direction of the slit 31 for hangers.

The bent part 31c of the slit 31 for the ear is disposed lower than the center 31d of the slit for the ear, so when the ear is passed through the slit 31 for the ear and the ear 30 is hung on the ear, The part 35 (refer to FIG. 1 ) along the upper slit 31 b of the ear hanging portion 30 is spread over a longer distance from the ear portion and bends away from the main body portion 10 . That is, the upper part of the main body part 10 is pulled back more strongly. Thereby, the bending portion 81 can be sufficiently bent as shown in FIG. 4 .

In particular, when the vertical width dimension L1 is greater than the vertical width dimension L2 as described above, the bent portion 31c of the slit 31 for the hanger is arranged lower than the center 31d of the slit for the hanger. Since the elongation of the upper connection part 32 of the ear is suppressed, the upper part of the main body part 10 can be pulled back more strongly, and the bending part 81 can be fully bent.

In the case of this embodiment, the lower end of the slit lower part 31a for the ear and the side edge 51a of the first sheet 51 are arranged close to each other, and the upper end of the slit upper part 31b for the ear is connected to the side of the first sheet 51. The sides 51a are arranged close to each other. Thus, the elongation of the ear upper connecting portion 32 and the ear lower connecting portion 33 can be moderately suppressed, so that the upper end and the lower end of the side edge of the main body 10 can be sufficiently pulled by the ear 30 .

Also, in the case of this embodiment, the distance between the lower end of the slit lower part 31a for hanging ears and the outer edge 26 of the heating element 20 and the distance between the upper end of the slit upper part 31b for hanging ears and the outer edge 26 of the heating element 20 are determined. Set to the same distance from each other.

Also, it is preferable to arrange the center 20c of the heating element 20 in the vertical direction and the center position in the vertical direction of the opening for hanging ears (in the example of FIG. 1 , the center of the slit for hanging ears 31d) to be arranged at the same height as each other. With such a configuration, the bending portion 81 can be bent more reliably. The height difference between the center 20c and the central position in the vertical direction of the opening for the ear (such as the center 31d of the slit for the ear) is preferably, for example, 3 cm or less, more preferably 2 cm or less, and still more preferably 1 cm or less.

Also, when a plurality of heat generating elements 20 are arranged in the first part 11 or the second part 12 of the main body 10, it is preferable to connect the central position of the aggregate of the plurality of heat generating elements 20 to the opening for the ear. The central positions in the up-down direction are arranged at mutually equal height positions, and the height difference thereof is, for example, preferably 3 cm or less, more preferably 2 cm or less, and still more preferably 1 cm or less.

Furthermore, in the present invention, the shape of the slit 31 for hanging ears is not limited to the folded line shape as in the present embodiment, and may also be formed in a curved shape protruding toward a direction (side) away from the main body portion 10 ( arc, etc.).

The slit 54 can be widely opened in an inverted V shape or an inverted U shape. That is, when the heating device 100 is worn on the face as shown in FIG. 4 , the slit 54 can be largely opened in an inverted V shape or an inverted U shape. Thereby, outside air can be more smoothly introduced from below the main body part 10 toward between the lower part of the main body part 10 and the face.

Moreover, by joining the edge portions of the left and right sides of the notch shape portion 55, that is, a pair of pre-bonded portions 56, the upper connection portion 61b of the three-dimensional structure portion 60 can be formed as shown in FIGS. Heat appliance 100.

The lower connecting portion 61a of the three-dimensional structure portion 60 is, for example, a portion where the part on the side of the first part 11 and the part on the side of the second part 12 are originally connected to each other in the first sheet 51 and the second sheet 52 .

Moreover, the method of forming the three-dimensional structure portion 60 is not limited to this example, for example, it can be formed by forming a vertically extending upper edge portion of the central portion of the main body portion 10 in the first sheet 51 and the second sheet 52. The linear slit (not shown) overlaps and joins the parts on the left and right sides of the slit to form the same three-dimensional structure portion 60 as shown in FIG. 1 and FIG. 2 .

In this case, the upper connecting portion 61b is provided on the first sheet 51 and the second sheet 52 Among them, the part on the side of the first part 11 and the part on the side of the second part 12 are originally connected to each other. On the other hand, the lower connecting portion 61 a is formed by joining the edge portions of the left and right sides of the slit connected to the upper side of the slit 54 to each other.

Alternatively, the three-dimensional structure portion 60 may be formed by embossing (pressurizing) on the upper portion of the central portion in the width direction of the main body portion 10 .

Alternatively, the three-dimensional structure part 60 may be formed by partially adding rubber fibers to the upper part of the central part in the width direction of the main body part 10, and contracting this part in the width direction.
