Hereinafter, a preferred embodiment of the present invention will be described using drawings. In addition, in all drawings, the same constituent elements are given the same symbols, and repeated descriptions will be appropriately omitted.

First, the heating device 100 according to this embodiment will be described with reference to FIGS. 1 to 5. FIG. 1 shows a state where the main body portion 10 and the pair of left and right ear-mounting portions 30 of the heating device 100 are flatly developed. In FIG. 1, the heating device 100 is shown as a face on the face side when the heating device 100 is worn on the user's face. FIG. 2 shows a state in which the heating device 100 is folded in half (after the heating device 100 is folded into two folds) with the heating device 100 folded in half at the central portion in the widthwise direction of the body portion 10 in the wearing state with the face on the face side as the inside. That is, FIG. 2 shows a state where the following first portion 11 and second portion 12 of the main body portion 10 overlap with each other, and the left ear mounting portion 30 and the right ear mounting portion 30 overlap each other. In addition, in FIG. 2, the first portion 11 of the main body portion 10 of the heating appliance 100 is shown as a surface facing outward when the heating appliance 100 is worn on the face of a user.

FIG. 3 shows a cross section obtained by cutting the heating appliance 100 in a horizontal and horizontal direction consistent with the arrangement direction of the first part 11 and the second part 12 in a state where the heating appliance 100 is unfolded (along FIG. 1). A cross-section of the line AA), in a state where the heating device 100 is worn on a user's face, a face facing the face is shown on the upper side, and a face facing outside is shown on the lower side. In this embodiment, when there is no special explanation, the description of the positional relationship (upper-lower relationship, etc.) of each component of the heating appliance 100 refers to wearing the heating appliance 100 on the top of the head as shown in FIG. 4. The positional relationship of the user's face with the neck in a lower position will be described.

As shown in any one of FIGS. 1 to 4, the heating device 100 according to this embodiment includes a main body portion 10 that is worn along the face, a heating element 20 that is provided on the main body portion 10, and a pair of ear-mounting portions. 30, which are respectively provided at both ends of the body portion 10 in the widthwise direction. Each of the pair of ear-mounting portions 30 has an ear-mounting opening 30a. The hanging ear opening 30 a preferably extends along the side edge of the main body portion 10 (formed in a longitudinally long shape in the longitudinal direction of the side edge of the main body portion 10). In the case of this embodiment, the ear-mounting opening 30a is a folding-line-type ear-mounting slit 31 which does not substantially have a width. The pair of ear-mounting parts 30 are respectively hung on the ears. The user can wear the warming device 100 by hanging the ear-mounting parts 30 on the ears. The ear-mounting portion 30 may be formed using a sheet integral with the main body portion 10 or may be provided by joining a person different from the main body portion 10 to the main body portion 10.

As shown in FIG. 1, in a state where the body portion 10 and the pair of ear-mounting portions 30 are unfolded flatly, the distance between the pair of ear-mounting portions 30 is set to W, and the longitudinal dimension of the ear-mounting opening 30 a is set. When it is H, H / W is 0.2 or more. Here, the state in which the main body portion 10 and the pair of hanging ear portions 30 are flatly developed refers to a state in which the entire heating device 100 is spread out as flat as possible, and the entire heating device 100 is naturally placed ( However, in the case where the heating device 100 is not provided with a tension to stretch the surroundings, and the heating device 100 includes the three-dimensional structure portion 60 described below, the entire strain of the three-dimensional structure portion 60 is equalized). The distance W is, for example, a distance between the pair of ears 30 at the same height position as the center 20c of the heating element 20 above and below in a state where the entire heating device 100 is spread as flat as possible. As shown in FIG. 1, the distance between the pair of ear mounting portions 30 is at the same height as the center 20 c above and below the heating element 20, and the edges of the pair of ear mounting openings 30 a facing away from the main body portion 10 are at the same height. Distance (see also FIG. 7 (a), FIG. 7 (b), and FIG. 8 described below as variations). The longitudinal dimension H of the ear opening 30a is the size of the ear opening 30a in a direction orthogonal to the arrangement direction (distance W direction in FIG. 1) of the pair of ear ears 30, that is, the size of the ear opening 30a The difference in height between the upper end and the lower end (the difference in height between the lower end of the lower portion 31a of the mounting ear and the upper end of the upper portion 31b of the mounting ear).

The heating device 100 of the present invention has a structure in which the longitudinal dimension H of the ear opening 30a and the distance W between the pair of ear portions 30 are larger than a certain degree or more. Thereby, when the heating appliance 100 is worn, the side edge portion (curved 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 faced from the side of the main body portion 10. The external atmosphere is smoothly introduced into the face, so that the heating element 20 can generate heat more uniformly. Furthermore, the reason why the curved portion 81 is formed is that a person's face has a shape protruding toward the front, and the ear portion is located further behind the eyes or cheeks.

More specifically, the bent portion 81 is bent so as to satisfy the following conditions (1) and (2), for example. (1) "The upper ear portion 30 is closer to the main body portion 10 side than the opening ear opening 30a (in FIG. 1, the ear ear slit 31 in Fig. 1) and along the upper and lower ends of the portion of the body ear portion 30 Part ", or" the upper and lower ends of the part along the side edge part of the body part 10 along the ear opening 30a "is relatively backward, and is arranged near the part of the cheek adjacent to the front side of the ear part. (2) "the middle portion of the ear-mounting portion 30 that is closer to the body portion 10 side than the ear-mounting opening 30a and along the up-down direction of the portion of the ear-mounting opening 30a", or "the side edge portion of the body portion 10 The middle part of the middle along the opening 30a for hanging ears is relatively located forward, and is arranged on the cheek away from the part adjacent to the front side of the ear to the side.

H / W is more preferably 0.25 or more, and by doing so, the bending portion 81 can be more surely bent. The H / W is preferably 0.7 or less, and more preferably 0.6 or less.

In addition, when the side of the opening 30a for mounting ears that is far from the main body portion 10 and the circumference connecting the upper end and the lower end is set to L, the H / L is preferably 0.6 or more. By doing so, the bending portion 81 can be bent more reliably. . In the case of this embodiment, the perimeter L becomes the sum of the length L11 and the length L12 shown in FIG. 1. In the case where the ear-mounting opening 30a does not substantially have a width of the ear-mounting slit 31 as in this embodiment, the circumference of the ear-mounting opening 30a on the side away from the main body portion 10 can be set as the ear-mounting slit. The total extended length of the slit 31, that is, the sum of the length dimension of the lower portion 31a of the mounting ear and the length dimension of the upper portion 31b of the mounting ear. H / L is more preferably 0.8 or more. H / L is 1 or less.

In the case of this embodiment, the main body portion 10 has a sheet shape (planar shape) of the three-dimensional structure portion 60 described below, and is formed in a size that can cover the face from the eyes to the cheeks. Here, the covering of the eye portion by the body portion 10 means covering the entire front of the eye socket (around the eye portion) (front side). The covering of the cheek by the body portion 10 means covering the front (front side) of at least the lower end position of the cheek bone. That is, the portion from the eye to the cheek where the body portion 10 covers the face refers to a region covering the range from the upper part of the periphery of the eye to the lower part of the cheekbone. Since the main body portion 10 is formed to have a size that can cover the above-mentioned parts, the face covered by the main body portion 10 can be warmed in a wide range by the heat generating body 20 disposed on the main body portion 10.

In the case of this embodiment, a slit 54 extending upward from the lower edge of the main body portion 10 is formed at the central portion in the widthwise direction of the main body portion 10. It should be noted that the slit 54 is not limited to a linear (straight, etc.) slit, and may be a cut-out portion having a shape such as an inverted V shape or an inverted U shape. In the case of this embodiment, the slit 54 is a straight slit in the folded state as shown in FIG. 2, but is opened in an inverted V shape in the unfolded state as shown in FIG. 1. A slit 54 extending upward from the lower edge of the main body portion 10 is formed at the central portion in the widthwise direction of the main body portion 10, thereby the external atmosphere can be smoothly introduced from below the main body portion 10 to the lower portion of the main body portion 10 and Between the faces, the external air can be supplied to the heat generating body 20 to heat the heat generating body 20.

In the case of this embodiment, the upper edge of the main body portion 10 extends substantially horizontally, or slightly rises and inclines toward the central portion (formed as a mountain shape protruding upward), at the upper portion of the central portion in the widthwise direction of the main body portion 10, A three-dimensional structure portion 60 is formed in a curved shape with the upper portion protruding toward the front (details will be described later). Therefore, the upper edge of the central portion in the widthwise direction of the main body portion 10 can be easily brought into close contact with or close to the forehead. Thereby, the face covered by the main body portion 10 can be warmed over a wide range and sufficiently.

As described above, according to the heating device 100, the face can be warmed in a wide range by the heating element 20 in a state where the body portion 10 covers the face from the eyes to the cheeks. In addition, the external atmosphere can be smoothly introduced from the bent portion 81 along the ear opening 30a, and the external atmosphere can also be smoothly introduced from below the main body portion 10, so that the entire heating element 20 can generate heat. Thereby, a large area of the face can be warmed more fully.

Since the heating appliance 100 includes the three-dimensional structure part 60, when the heating appliance 100 is worn, a convex shape is formed on the upper part of the central part in the widthwise direction of the body part 10, and the side edge part of the body part 10 is also easy to bend. , The side edge portion (curved portion 81 shown in FIG. 4) of the main body portion 10 can be more easily convexly bent forward. Therefore, the external atmosphere can be more smoothly introduced from the side of the main body portion 10 between the main body portion 10 and the face, and the entire heating body 20 can be more uniformly heated.

In the case of this embodiment, as described below, the heating device 100 is a steam heating device. Therefore, as in the case of the air described above, it is possible to suppress the escape of steam from the gap between the upper edge of the central portion in the widthwise direction of the body portion 10 and the face, and to allow steam to fill the space between the body portion 10 and the face.

The body portion 10 is formed in a size and shape that can cover both eyes and cheeks. The main body portion 10 includes a first portion 11 covering a portion from the left eye to the left cheek, and a second portion 12 covering a portion from the right eye to the right cheek. The first portion 11 and the second portion 12 are formed to have substantially the same shape and size as each other. In FIG. 1, the first portion 11 and the second portion 12 are arranged side by side, and are separated from each other through the slit 54 below the main body portion 10.

The planar shape of the main body portion 10 is not particularly limited. For example, as shown in FIG. Furthermore, since the slit 54 is formed in the main body portion 10, an inverted V-shaped or inverted U-shaped notch shape is formed in the lower portion of the central portion in the widthwise direction of the main body portion 10. In addition, the planar shapes of the first portion 11 and the second portion 12 may be, for example, a substantially quadrangular shape (for example, a slightly long rectangular shape) that is one circle larger than the heating element 20.

In the case of this embodiment, the main body portion 10 preferably does not have a slit (including a notch-shaped portion) extending downward from the upper edge of the main body portion 10. With this configuration, the upper edge of the main body portion 10 can be continuously in close contact with the forehead of the user in the widthwise direction, and warm air or steam can be filled between the main body portion 10 and the face. Also, in FIG. 1, the upper edge of the main body portion 10 slightly rises and slopes toward the center (formed as a mountain shape protruding upward), but in a state where the heating device 100 is folded in half as shown in FIG. The upper edge of 10 is inclined downward toward the side edge of the main body portion 10. In the case of this embodiment, the lower edge of the main body portion 10 extends substantially horizontally, for example, except for the formation portion of the slit 54. Furthermore, in a state where the heating device 100 is folded in half as shown in FIG. 2, for example, the lower edge of the main body portion 10 is inclined downward toward the side edge of the main body portion 10.

The size of the main body portion 10 in the up-down direction orthogonal to the widthwise direction is set, for example, so that the main body portion 10 can cover from a portion slightly above the upper edge of the eyebrow peak to a portion slightly below the corner of the mouth. In addition, the side edge portion of the main body portion 10 covers, for example, the vicinity of the rear end of the cheek (the part of the cheek that is adjacent to the front side of the ear). In addition, in the first portion 11 and the second portion 12, the portion along the slit 54 extends along the decree line from the nose side, for example. The lower ends of the first portion 11 and the second portion 12 are located lower than the lower lip, for example. More specifically, for example, the portion along the slit 54 in the heating element 20 (the inner edge 25 shown in FIGS. 1 and 4) extends along the decree, and the portion along the slit 54 in the body portion 10. The lower end covers the corners of the mouth. The three-dimensional structure portion 60 covers, for example, a portion from the lower end portion of the central portion in the widthwise direction of the forehead to the upper end portion (nasal root) of the bridge of the nose. In the case of this embodiment, the three-dimensional structure portion 60 is configured to include a portion 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 portion 60 may not include the upper edge of the main body portion 10 (it may be disposed at a position lower than the upper edge of the main body portion 10).

In the case of this embodiment, the heating device 100 is configured to include a first sheet material 51 and a second sheet material 52 that is arranged to overlap the first sheet material 51. Each of the first sheet material 51 and the second sheet material 52 may include a single-layer sheet or a laminate of a plurality of sheets. Each of the first sheet 51 and the second sheet 52 includes a flexible material. Examples of the material of the first sheet 51 and the second sheet 52 include non-woven fabrics, woven fabrics, other knitted fabrics, resin films such as polyethylene and urethane, porous bodies, and any two of them. A combination of the above.

The first sheet 51 is formed in the shape of the main body portion 10, for example. On the other hand, the second sheet material 52 is formed in the same shape as the entire shape of the heating device 100. More specifically, as shown in FIG. 1, the left end portion and the right end portion of the second sheet material 52 respectively protrude from the first sheet material 51, and the protruding portions constitute left and right ear mounting portions 30, respectively. 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 side opposite to the face (that is, outward).

As shown in FIG. 3, mutually facing surfaces of the first sheet material 51 and the second sheet material 52 are joined to each other at the joint portion 53. The first sheet material 51 and the second sheet material 52 may be joined by adhesion or adhesion, or may be joined by heat sealing. In the case of this embodiment, the joint portion 53 is configured by, for example, hot-melt. The joint portion 53 is arranged, for example, over the entire periphery of the peripheral edge portion of the main body portion 10 and from the upper edge to the lower edge of the central portion in the widthwise direction of the main body portion 10. More specifically, the joint portion 53 is arranged, for example, on the entire periphery of the peripheral portion of the first portion 11 and on the entire periphery of the peripheral portion of the second portion 12. In addition, the joining portion 53 not only joins the first sheet 51 and the second sheet 52, but also, for example, joins the first sheet 51 or the second sheet 52 and the heating element 20.

A heat generating body 20 is provided between the first sheet 51 and the second sheet 52. More specifically, a heating element 20 is provided between each of the first portion 11 and the second portion 12 between the first sheet 51 and the second sheet 52.

In the case of this embodiment, the arrangement area of the heating element 20 is set to a size covering a region from the eyes to the lower part of the cheek than the corner of the mouth. Thereby, a large part of the face from the eyes to the cheek (the part of the cheek lower than the corner of the mouth) can be warmed more fully.

In more detail, the heating element 20 provided in the first portion 11 is set to cover a range from the left eye to the left cheek to a portion lower than the corner of the left mouth, and the heating element 20 provided in the second portion 12 is set. The size is set to cover the area from the right eye to the right cheek, which is lower than the corner of the right mouth. The heating element 20 provided in the first portion 11 is set to cover the left temple, and the heating element 20 provided in the second portion 12 is set to cover the right temple.

Here, in the first part 11, either a single heating element may be provided, or a heating element group as a collection of a plurality of heating elements arranged adjacent to each other or near ground may be provided. Similarly, in the second part 12, either a single heating element may be provided, or a heating element group as an assembly of a plurality of heating elements arranged adjacent to each other or near ground may be provided. The heating element 20 refers to a single heating element or a group of heating elements mentioned herein. Therefore, the arrangement area of the heating element 20 may be an arrangement area of an individual heating element or an arrangement region of a heating element group.

The planar shape of the arrangement area of the heating elements 20 in the first portion 11 and the second portion 12 is not particularly limited. In the case of this embodiment, for example, the arrangement region 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 arrangement region of the heating element 20 is inclined upward toward the side edge of the main body portion 10, for example. Therefore, the upper and lower dimensions of the area between the upper edge of the disposition area of the heating body 20 and the upper edge of the main body portion 10 (ie, the area on the upper side of the heating body 20 where the heating body 20 does not exist) are, for example, the width of the main body portion 10 The direction center is gradually enlarged (toward the side edge of the main body portion 10). Thereby, the upper part of the central part in the widthwise direction of the main body part 10 has a curved shape protruding toward the front, and it is easy to put the upper edge of the heating device 100 in close contact with the forehead or wear it close to the ground. Further, a portion of the heating element 20 along the slit 54 (the inner edge 25 shown in FIGS. 1 and 4) extends parallel to the slit 54, for example. The inner edge 25 is arranged near the ground with respect to the slit 54, for example. On the other hand, the edge portion (outer edge 26 shown in FIG. 1) on the side opposite to the inner edge 25 in the heating element 20 extends along the side edge 51 a (FIG. 1) of the first sheet 51 (for example, the side The sides 51a extend in parallel). The outer edge 26 is, for example, disposed close to the side 51a.

As shown in FIG. 3, the heating element 20 is configured to include, for example, a first covering sheet 21, a second covering sheet 22, and a sheet-like structure held between the first covering sheet 21 and the second covering sheet 22.热 材 23。 Heating material 23.

The first covering sheet 21 and the second covering sheet 22 are formed to have the same shape and size, for example. In addition, they overlap with each other so that their outer contour lines coincide, and their peripheral edges are joined to each other. Thereby, the storage body which accommodates the heat generating material 23 inside is comprised. The joining of the first covering sheet 21 and the second covering sheet 22 can be performed by adhesion or adhesion, or by heat sealing. The planar shapes of the first covering sheet 21 and the second covering sheet 22 are not particularly limited. In the case of this embodiment, the first covering sheet 21 and the second covering sheet 22 are, for example, formed into rectangular shapes (for example, Square). The first covering sheet 21 is arranged 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 arranged on the second sheet 52 side, that is, when the warming device 100 is worn. It is the side opposite to the face side (front side).

The heat generating material 23 is configured to include an oxidizable metal. The heat generating material 23 generates heat by an oxidation reaction caused by the contact between the oxidized metal and oxygen. In the case of this embodiment, the heat generating material 23 is configured to generate heated water vapor by using heat generated during an oxidation reaction caused by the contact between the oxidized metal and the acid. The heat generating material 23 includes, for example, an oxidized metal, a reaction accelerator, an electrolyte, and water.

The heat generating material 23 is formed in a sheet shape, for example. A single heat-generating material 23 or a plurality of heat-generating materials 23 can be accommodated in a container including the first covering sheet 21 and the second covering sheet 22. The "single heating element" is configured to include one storage body and one or a plurality of heat generating materials 23 stored in the one storage body. On the other hand, the above-mentioned "heat generating body group" is constituted by arranging a plurality of "individual heat generating bodies" having such a configuration adjacent to each other or near grounding. For example, one or a plurality of heat generating materials 23 are arranged in a rectangular (eg, square) region smaller than the first covering sheet 21 and the second covering sheet 22. 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 edge 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 portion 53 joins the first covering sheet 21 and the first sheet 51 to each other, or joins the second covering sheet 22 and the second sheet 52 to each other. In the case of the present embodiment, for example, as shown in FIG. 3, the joint portion 53 joins the first covering sheet 21 and the first sheet 51 to each other, and also connects the second covering sheet 22 and the second sheet 52 to each other. Join. In this way, the left and right heating elements 20 are held inside the first portion 11 and the second portion 12, respectively. Furthermore, in the central portion (except the peripheral portion) of the heating element 20, for example, the heating element 20 and the first sheet 51 are non-joined to each other, and the heating element 20 and the second sheet 52 are non-joined to each other (see image 3).

At least one of the first covering sheet 21 and the second covering sheet 22 of the heat generating body 20 is breathable. In the case of this embodiment, the first covering sheet 21 has air permeability. The first covering sheet 21 has higher air permeability than the second covering sheet 22. The second covering sheet 22 may be either air-permeable or substantially non-air-permeable.

Furthermore, the first covering sheet 21 has air permeability so that air and water vapor can pass therethrough. On the other hand, the second covering sheet 22 is less air-permeable or non-breathable than the first covering sheet 21. The air permeability of the first covering sheet 21 is preferably 1,000 seconds / 100 ml or more, and more preferably 2000 seconds / 100 ml or more in terms of warming a large area of the face more fully. In addition, it is preferably 50,000 seconds / 100 ml or less, more preferably 20,000 seconds / 100 ml or less, and even more preferably 10,000 seconds / 100 ml or less. The air permeability is a value measured according to JIS (Japanese Industrial Standards) P8117, and is defined by the time that 100 ml of air passes through an area of 6.45 cm ² under a fixed pressure. The air permeability can be measured by Wang Yan type air permeability meter or a measuring machine based on this.

As such a breathable sheet, a porous sheet made of a resin having moisture permeability but not having water permeability, or a sheet made of a resin having breathable holes can be used. For example, polyethylene, polypropylene, or ethylene can be used. -Vinyl acetate copolymers and the like. As the porous sheet made of a resin, a melt-kneaded product of a thermoplastic resin and an organic or inorganic filler having no compatibility with the resin can be used to obtain a film by uniaxially or biaxially stretching it. In addition, it is possible to use a person having micropores in a non-breathable sheet or a gas-impermeable sheet using a needle or the like, or a gas-permeable sheet further having micropores in a needle or the like. The thickness of the air-permeable sheet is preferably 5 μm or more and 200 μm or less.

On the other hand, the second covering sheet 22 may be either a breathable sheet or a non-breathable sheet. When the second covering sheet 22 is an air-permeable sheet, the air permeability is preferably 80,000 seconds / 100 ml or more. When the second covering sheet 22 is a non-breathable sheet, a laminated sheet obtained by laminating a non-breathable resin film and paper can be used as the non-breathable sheet. The first covering sheet 21 and the second covering sheet 22 may each include one sheet, or may include a laminate of a plurality of sheets. As such a laminate, a laminate sheet obtained by laminating a nonwoven fabric and a breathable sheet, or a laminate sheet obtained by laminating a knitted fabric and a breathable sheet can be used.

In the case of this embodiment, as described above, the heat generating material 23 is a person that generates water vapor by generating heat, the first covering sheet 21 has moisture permeability, and the first sheet 51 has moisture permeability. Therefore, water vapor can be released through the surface on the face side in the body portion 10, and the water vapor can be brought into contact with the face. That is, the heat generating material 23 is a generator accompanied by water vapor when generating heat, and the heating device 100 is configured such that water vapor is released to the outside through the surface of the body portion 10 that becomes the face side.

The shape of the ear-receiving portion 30 is not particularly limited. In the case of this embodiment, the ear-receiving portion 30 is formed in a vertically long shape (lengthwise shape). The upper and lower dimensions of the ear part 30 are set to, for example, the same size as the upper and lower dimensions of the body part 10. Since the ear-mounting portion 30 is vertically long, the upper end portion and the lower-end portion of the side edge portion of the body portion 10 can be pulled toward the rear by the ear-mounting portion 30, respectively, so that the bending portion 81 can be sufficiently bent.

In the case of this embodiment, the ear-mounting part 30 has a long ear-mounting slit 31 as the ear-mounting opening 30a. When the warming appliance 100 is worn, as shown in FIG. 4, the body part 10 is closely attached to the part of the face from the eye 75 to the cheek 76, and the left and right ear parts 74 enter the left and right hanging ear parts 30. After the ear slit 31, the ear-hanging portion 30 is hung behind the ear portion 74.

More specifically, the height position of the lower end of the ear-mounting slit 31 is set, for example, to a height position substantially equal to the lower end of the heating element 20. On the other hand, the height position of the upper end of the mounting ear slit 31 is set lower than the upper end of the heating element 20, and is set to the center 20c of the heating element 20 in the vertical direction (FIG. 1, FIG. 1). Figure 2) Further up. That is, the ear-mounting slit 31 is based on the heating element 20 and is arranged slightly below. With the arrangement of the ear-mounting slits 31 as described above, 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 portion can be sufficiently secured. 60 the size of the gap with the face. In addition, since the upper portion of the main body portion 10 can be pulled more strongly toward the rear, the bending portion 81 can be sufficiently bent.

The portion between the upper end of the ear-mounting slit 31 and the upper edge of the ear-mounting portion 30 becomes the ear-mounting upper connecting portion 32, which is closer to the body portion 10 side of the ear-mounting portion 30 than the ear-mounting slit 31. The part is connected to the upper side of the ear-mounting slit 31 from the side farther from the body part 10 than the ear-mounting slit 31. Similarly, the portion between the lower end of the ear-mounting slit 31 and the lower edge of the ear-mounting portion 30 becomes the ear-mounting lower connection portion 33, which is closer to the body than the ear-mounting slit 31 in the ear-mounting portion 30. The part on the side of the part 10 and the part farther from the side of the body part 10 than the ear-mounting slit 31 are connected to the lower side of the ear-mounting slit 31. In the case of this embodiment, the upper and lower width dimension L1 (FIG. 1, FIG. 2) of the upper ear connecting portion 32 is set larger than the upper and lower width dimension L2 (FIG. 1, FIG. 2) of the lower ear connecting portion 33. In other words, the distance between the upper edge of the ear-mounting portion 30 and the upper end of the ear-mounting slit 31 is greater than the distance between the lower end of the ear-mounting slot 31 and the lower edge of the ear-mounting portion 30. Thereby, it is possible to suppress the stretching of the upper connecting portion 32 of the hanging ear when the heating appliance 100 is worn, and when the hanging ear portion 30 is hung on the ear, the side edge portion of the main body portion 10 can be hanged by the hanging ear portion 30. Pull the upper part towards the rear more fully. As a result, as shown in FIG. 4, the bent portion 81 can be sufficiently bent, and the portion of the body portion 10 that is closer to the center in the widthwise direction than the bent portion 81 can be satisfactorily applied to the face. On the other hand, since a moderate stretching of the lower connecting portion 33 of the hanging ear can be achieved, the hanging ear portion 30 can be satisfactorily attached to the ear regardless of the size of the ear portion of the user.

Here, the upper and lower width dimension L1 may be, for example, the upper edge of the ear-mounting portion 30 on the straight line AX1 (FIG. 1, FIG. 2) connecting the upper end and the lower end of the ear-mounting slit 31 and the ear-mounting slit 31. The distance from the top. The vertical width dimension L2 may be a distance between the lower edge of the ear-mounting portion 30 on the straight line AX1 (FIGS. 1 and 2) and the lower end of the ear-mounting slit 31.

The ear-mounting slit 31 is convexly curved in a direction away from the main body portion 10 in the widthwise direction, for example. That is, in the expanded state shown in FIG. 1, the left ear mounting slit 31 is convexly curved toward the left, and the right ear ear slit 31 is convexly curved toward the right. In more detail, in the case of this embodiment, the ear-mounting slit 31 is formed in the shape of a fold line which is convexly bent in a direction away from the main body portion 10 in the widthwise direction, for example. The ear-mounting slit 31 includes, for example, a linear ear-mounting slit lower portion 31 a constituting a lower portion of the ear-mounting slit 31 and a linear ear-mounting slit forming an upper portion of the ear-mounting slit 31. Upper 31b. Further, the bent portion 31c of the ear-mounting slit 31, which is the boundary between the ear-mounting slit lower portion 31a and the ear-mounting slit upper portion 31b, is disposed at a relatively central position above and below the ear-mounting slit 31 ( The center of the mounting ear slit 31d) is further down.

The bent portion 31c of the ear-mounting slit 31 is disposed lower than the center 31d of the ear-mounting slit. Therefore, when the ear portion passes through the ear-mounting slit 31 and the ear-mounting portion 30 is hung on the ear, The portion 35 (see FIG. 1) of the ear-mounting portion 30 along the upper portion of the ear-mounting slit 31 b (see FIG. 1) is widened over a longer distance and is bent away from the body portion 10. That is, the upper portion of the main body portion 10 is pulled more strongly toward the rear. Thereby, as shown in FIG. 4, the bending part 81 can fully bend.

In particular, when the vertical width dimension L1 is larger than the vertical width dimension L2 as described above, the bent portion 31c of the mounting ear slit 31 is disposed lower than the center 31d of the mounting ear slit. Since the elongation of the upper connecting portion 32 of the mounting ear is suppressed, the upper portion of the main body portion 10 can be pulled more strongly toward the rear, so that the bent portion 81 is sufficiently bent.

In the case of this embodiment, the lower end of the lower portion 31a of the mounting ear and the side 51a of the first sheet 51 are arranged close to each other, and the upper end of the upper portion 31b of the mounting ear slit and the side of the first sheet 51 The sides 51a are arranged close to each other. Thereby, the elongation of the hanging ear upper side connecting portion 32 and the hanging ear lower side connecting portion 33 can be moderately suppressed. Therefore, the upper end portion and the lower end portion of the side edge portion of the body portion 10 can be sufficiently pulled by the hanging ear portion 30. In the case of this embodiment, the distance between the lower end of the lower portion 31a of the mounting ear and the outer edge 26 of the heating element 20 and the distance between the upper end of the upper portion 31b of the mounting ear and the outer edge 26 of the heating element 20 Set the distances equal to each other.

Further, it is preferable that the center 20c of the heating element 20 above and below and the center position of the opening for the hanging ears above and below (in the example of FIG. 1 the center of the slit for the hanging ears 31d) are arranged at the same height. With this configuration, the curved portion 81 can be bent more reliably. The height difference between the center 20c and the center position above and below the opening for mounting ears (for example, the center of the slit for mounting ears) is preferably 3 cm or less, more preferably 2 cm or less, and even more preferably 1 cm or less. . In the case where a plurality of heating elements 20 are arranged in the first portion 11 or the second portion 12 of the main body portion 10, it is preferable that the center position of the assembly of the plurality of heating elements 20 and the opening for mounting ears The upper and lower center positions are arranged at equal height positions, and the difference in height between them is preferably 3 cm or less, more preferably 2 cm or less, and even more preferably 1 cm or less.

In addition, in the present invention, the shape of the ear-mounting slit 31 is not limited to the polygonal line shape as in this embodiment, and may be formed in a curved shape protruding in a direction (side) away from the main body portion 10 ( Arc, etc.).

Here, the three-dimensional structure unit 60 will be described. As described above, the main body portion 10 is configured to include: the first portion 11 covering the part from one eye (left eye) to the cheek (left cheek) on one side; and the second portion 12 covering the other From the eye (right eye) on one side to the cheek (right cheek) on the other side. In the case of this embodiment, the three-dimensional structure portion 60 is a connection portion 61 that connects the first portion 11 and the second portion 12 to each other above the slit 54. The connection portion 61 is configured to include a lower connection portion 61a extending vertically, and an upper connection portion 61b adjacent to and above the lower connection portion 61a and extending vertically. As shown in FIG. 2, in a state where the heating appliance 100 is folded in half, the lower connection portion 61 a and the upper connection portion 61 b do not exist on the same straight line with each other, but are bent at each other's boundary portions. More specifically, the lower connection portion 61 a and the upper connection portion 61 b are bent at an angle α. When the main body portion 10 is unfolded, the upper portion of the central portion in the widthwise direction of the main body portion 10 has a curved shape protruding toward the front (see FIG. 4). The angle α (FIG. 2) is preferably 120 degrees or more and 170 degrees or less, and more preferably 130 degrees or more and 160 degrees or less. By having such an angle, when wearing the heating device 100, the upper edge of the central portion in the widthwise direction of the main body portion 10 can be in close contact with or close to the forehead 71 (see FIG. 4), and the face can be sufficiently secured. The gap between the three-dimensional structure part 60 and the gap is filled with a sufficient volume of warm air.

As described above, the slit 54 is formed in the central portion in the widthwise direction of the main body portion 10. The slit 54 extends upward from the lower edge of the main body portion 10. Here, the upper and lower dimensions H2 (FIG. 2 and FIG. 5) of the slit 54 are preferably 40% or more of the upper and lower dimensions H1 of the central portion of the main body portion 10. The vertical dimension H2 is more preferably 50% or more of the vertical dimension H1. If the upper and lower dimensions H2 are more than 40% of the upper and lower dimensions H1, when the main body portion 10 is unfolded and the three-dimensional structure portion 60 has a three-dimensional shape as shown in FIG. 1, the linear narrow portion is in a folded state as shown in FIG. 2. The slit 54 can be opened in a large V shape or a large U shape. That is, when the heating device 100 is worn on the face as shown in FIG. 4, the slit 54 may be opened substantially in an inverted V shape or an inverted U shape. Thereby, the external atmosphere can be introduced more smoothly from below the main body portion 10 toward between the lower part of the main body portion 10 and the face. For example, when the heating device 100 is worn on the face as shown in FIG. 4, it is preferable that the nose portion 72 and the mouth portion 73 are exposed through the slit 54, thereby making it easy to wear the heating device 100. Breathe gently. The upper and lower dimensions H2 are preferably 75% or less of the upper and lower dimensions H1, and more preferably 70% or less.

During use, the heating device 100 is taken out of the packaging bag, whereby the heating material 23 of the heating element 20 comes into contact with oxygen in the air, the heating material 23 generates heat and generates water vapor (steam warming), and the water vapor passes through the first The covering sheet 21 and the first sheet 51 are released to the outside. Therefore, since the user wears the heating device 100, the water vapor is supplied to the face of the user. This makes the user's face warm, for example, with a hot towel. As described above, the heating device 100 of the present embodiment is a steam heating device. In order to wear the warming device 100, the first sheet 51 of the main body portion 10 is the face side, and the first portion 11 and the second portion 12 are closely adhered to the positions from the left and right eye portions 75 to the cheek 76, respectively, and The pair of ear-hook portions 30 are respectively hung on the left and right ear portions 74.

Here, an example of a method of forming the three-dimensional structure portion 60 will be described using FIG. 5. The heating appliance constituting sheet 120 shown in FIG. 5 is a material for making the heating appliance 100. The difference between the heating appliance configuration sheet 120 and the heating appliance 100 is that the pair of left and right pre-joined portions 56 shown in FIG. 5 are not joined to each other, and are otherwise configured similarly to the heating appliance 100. For example, as shown in FIG. 5, in the first sheet 51 and the second sheet 52, a V-shaped notch-shaped portion 55 is formed on the upper edge portion of the central portion in the widthwise direction of the main body portion 10. The warming device constitutes the sheet 120.

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

In addition, the method of forming the three-dimensional structure portion 60 is not limited to this example. For example, the upper edge portion of the central portion in the widthwise direction of the main body portion 10 in the first sheet 51 and the second sheet 52 may be extended vertically. A linear slit (not shown) is formed such that the left and right sides of the slit overlap each other and are joined to form a three-dimensional structure portion 60 similar to that shown in FIGS. 1 and 2. Alternatively, the structures of the lower connection portion 61a and the upper connection portion 61b may be reversed from those of the present embodiment. In this case, the upper connection portion 61b is a portion of the first sheet 51 and the second sheet 52 in which the portion on the first portion 11 side and the portion on the second portion 12 side are originally connected to each other. On the other hand, the lower connection portion 61 a is formed by joining the edge portions on 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) the upper portion of the central portion in the widthwise direction of the main body portion 10. Alternatively, the three-dimensional structure portion 60 may be formed by setting the upper portion of the central portion in the widthwise direction of the main body portion 10 to a structure in which rubber fibers are locally added and the portion is shrunk in the widthwise direction.

The heating device 100 preferably has a maximum surface temperature of 38 to 70 ° C, for example.
