Refers to the range up to.

As shown in FIGS. 1 to 5, the heating tool 1 of the present embodiment includes a heat generating material 3, a main body 2 containing the heat generating material 3, and a pair of ears provided at the left and right ends of the main body 2. It is provided with hanging portions 4L and 4R. The heating tool 1 is attached to the face by hanging the ear hooks 4L and 4R on the corresponding ears of the left and right ears so that the main body 2 covers the left and right eyes and the periphery of each eye. .. Then, the heating tool 1 gives heat to the left and right eyes in contact with the main body 2 and the periphery of each eye when the heat generating material 3 housed in the main body 2 generates heat. Like the disposable body warmer, the heating tool 1 uses a heat-generating material 3 that uses the heat of reaction generated by the oxidation reaction as a heat source. The heating tool 1 according to the present invention is not limited to the one in which the heat of reaction generated by the heat generating material 3 accompanying the oxidation reaction is used as a heat source, and the heat generating material 3 is heated by, for example, irradiating with microwaves in a microwave oven or the like. It may have.

First, as the heat generating material 3, a powdery material that generates heat when it comes into contact with air can be used. Examples of this type of heat generating material 3 include an oxidizable metal, activated carbon, carbon black, a water retention agent (for example, wood powder, vermiculite, diatomaceous earth, pearlite, silica gel, alumina, a water-absorbent resin, etc.), and a metal salt (for example, Examples thereof include compositions containing appropriate contents of (salt, etc.) and water. The metal to be oxidized is a metal that emits heat of oxidation reaction, and examples thereof include one or more powders and fibers selected from iron, aluminum, zinc, manganese, magnesium, and calcium. Among these, iron powder is preferable from the viewpoints of handleability, safety, manufacturing cost, storage stability and stability. Examples of the iron powder include one or more selected from reduced iron powder and atomized iron powder. As the above-mentioned composition, a known composition conventionally used for disposable body warmers can be used.

As the heat generating material 3, a material other than a material that generates heat due to contact with air may be used. For example, a material that generates heat when irradiated with microwaves in a microwave oven or the like (for example, ceramic powder such as ferrite) may be used as the heat generating material 3.

Next, the main body 2 covers the left and right eyes and the periphery of each eye when the heating device 1 is attached to the face. The main body 2 is flat and horizontally long in a plan view, and is formed in a size sufficient to cover the left and right eyes and the periphery of each eye. The main body 2 has an upper edge 20 and a lower edge 21 along the horizontal direction and left and right side edges 22 and 23 along the vertical direction in a plan view, and the central position in the horizontal direction is parallel to the vertical direction. It has a symmetrical shape at the vertical center line 24 extending to.

In the present disclosure, the "horizontal direction" refers to a direction in the main body 2 that is parallel to the left-right direction (the direction connecting the left and right ears) of the face when the heating device 1 is attached to the face, and is the "vertical direction". "" Is a direction orthogonal to the lateral direction, and refers to a direction parallel to the vertical direction (direction connecting the forehead, nose, and jaw) of the face when the heating device 1 is attached to the face in the main body 2. In the present embodiment, the longitudinal direction of the main body 2 is the lateral direction. "Inside" refers to the vertical center line 24 side in the horizontal direction of the main body 2, and "outside" refers to the left and right side edges 22 and 23 opposite to the vertical center line 24 in the horizontal direction of the main body 2. Point to. The "left-right direction" defines the left-right direction based on the time when the user wears the heater 1 on his face and faces forward. The definition of these directions is not intended to limit the usage mode of the heating tool 1.

The upper edge 20 has a linear or uneven curved shape, while the lower edge 21 is located under the eyes when the heating device 1 is attached to the face, so that the lower edge 21 is laterally aligned with the shape of the nose. The central part of the direction has a concave shape. Further, the lower edge 21 extends diagonally downward with respect to the lateral direction from the lower end of the concavely constricted portion toward the left and right ends, and the lower left and right corners 25 and 26 of the main body 2 are lower. It bulges greatly to the side. As a result, the left and right corners 25 and 26 on the lower side of the main body 2 cover up to the cheekbones under the eyes when the heater 1 is attached to the face. The left and right corners 25 and 26 on the lower side of the main body 2 are rounded in the present embodiment, but they do not necessarily have to be rounded. The left and right side edges 22 and 23 have a linear shape in the present embodiment, but may have a curved shape that is convexly curved toward the outside.

The main body 2 is formed in a bag shape, and has a storage space inside which the heat generating material 3 can be sealed. The main body 2 includes two sheet materials 27A and 27B having the same shape on the front and back surfaces, and is formed into a bag shape by joining the portions along the outer peripheral edges of the two sheet materials 27A and 27B over the entire circumference. It is formed. Although heat welding (heat sealing) is used for joining the two sheet materials 27A and 27B in this embodiment, in addition to heat welding, known methods such as pressure bonding using a known adhesive and ultrasonic welding are known. Means may be used, or a combination thereof may be used.

The width dimension of the first joint portion 28 that joins the outer peripheral edges of the two sheet materials 27A and 27B is not particularly limited, and may be an appropriate width dimension. Further, the width dimension of the first joint portion 28 may be substantially the same over the entire circumference of the outer peripheral edge of the main body portion 2, or may be different as in the present embodiment. In the present embodiment, the first joint portion 28 has vertical edge portions along the left and right side edges 22 and 23 of the main body portion 2 rather than the width dimension of the horizontal edge portion along the upper edge 20 and the lower edge 21 of the main body portion 2. It is formed so that the width dimension of is wider. Further, the first joint portion 28 is formed so that the width dimension of the vertical edge portion along the left and right side edges 22 and 23 of the main body portion 2 becomes wider toward the upper side and the lower side, and further, the main body portion 2 It is formed so that the width dimension is the widest at the lower left and right corners 25 and 26.

In the main body 2, in addition to the first joint 28, two sheet materials 27A and 27B are also joined in the pair of second joints 29L and 29R. The pair of second joint portions 29L and 29R are arranged at positions corresponding to the left and right eyes when the heating tool 1 is attached to the face in the main body portion 2. One second joint 29L hits the left eye and covers it when the heater 1 is attached to the face, and the other second joint 29R hits the right eye and covers it when the heater 1 is attached to the face. In 2, it forms the eye covering part.

The pair of second joint portions 29L and 29R (mesh covering portions) are portions in which the heat generating material 3 is not housed in the present embodiment. The pair of second joint portions 29L and 29R (eye coating portions) are separated from the portion covering the periphery of the eyes (peripheral coating portion) in the main body portion 2, and the heat generating material accommodated in the adjacent peripheral coating portion. 3 is restricted from moving to a pair of second joints 29L, 29R (mesh coverings). The pair of second joint portions 29L and 29R (eye covering portions) have a horizontally long oval shape (including an elliptical shape), but the shape is not particularly limited as long as the eyes can be covered. For example, it may have a horizontally long rectangular shape or a rhombic shape.

In the main body 2, since the heat generating material 3 is not housed in the pair of second joints 29L and 29R (eye covering parts), the left and right eyes are accompanied by the heat generated by the heat generating material 3 when the heating tool 1 is attached to the face. It is designed not to overheat with high temperature heat. If the left and right eyes (eyeballs) are heated too much with high-temperature heat, the heat may cause denaturation of corneal proteins. Therefore, in the present embodiment, it is possible to prevent the left and right eyes (eyeballs) from becoming too warm when the heating device 1 is attached to the face.

The eye covering portion of the main body 2 may contain the heat generating material 3 as long as the filling rate of the heat generating material 3 is lower than that of the surrounding covering portion, but the left and right eyes (eyeballs) when the heating tool 1 is attached to the face. ) Is not overheated, and it is preferable that the heat generating material 3 is not contained. The "filling rate" in the present disclosure means the ratio of the weight of the heat-generating material 3 actually filled to the weight of the maximum heat-generating material 3 that can be filled in the eye covering portion and the surrounding covering portion. ..

Further, the main body 2 penetrates the eye coverings that hit the left and right eyes when the heater 1 is attached to the face, from the viewpoint that the left and right eyes (eyeballs) are not overheated when the heater 1 is attached to the face. It may be a hole. However, if the eye covering portion is a through hole, when the heating tool 1 is used as an eye mask at bedtime, the effect of the eye mask is lost because the main body portion 2 cannot block the external light. Further, when the heating tool 1 is attached to the face, it is not possible to give appropriate heat to the left and right eyes, and the heat generated from the heat generating material 3 escapes from the through hole to the outside, so that the heat is effectively applied to the surroundings of the eyes. It may not be possible to give. Therefore, as in the case of the heating tool 1 of the present embodiment, since the eye covering portion of the main body portion 2 is the second joint portions 29L and 29R, the effect of the eye mask is as compared with the case where the eye covering portion is a through hole. In addition, it is advantageous in that when the heating device 1 is attached to the face, it is possible to give appropriate heat to the left and right eyes, and it is possible to suppress the temperature of the heat given to the surroundings of the eyes from dropping too much. ..

The two sheet materials 27A and 27B constituting the main body 2 have flexibility so as to follow the surface shape of the face when the heater 1 is attached to the face. The materials of the two sheet materials 27A and 27B are not particularly limited, but it is preferable to use a resin film in consideration of strength and durability of the heat generating material 3 against heat generation.

The resin used for the above-mentioned resin film is not particularly limited, but a thermoplastic resin is preferable. Examples of the thermoplastic resin include polyethylene, polypropylene, polyester, polyamide, polyurethane, polystyrene, polyvinyl alcohol, polyvinyl chloride, polyvinylidene chloride, polycarbonate, ethylene-vinyl acetate copolymer, and polyethylene terephthalate. Among them, polyethylene, polypropylene, ethylene vinyl acetate copolymer, and polyethylene terephthalate can be preferably exemplified. These resins may be used alone or in combination of two or more.

Further, from the viewpoint of improving the feel of the heating tool 1, the two sheet materials 27A and 27B are laminated with a breathable woven cloth or non-woven fabric on the side opposite to the side facing the heat generating material 3 of the resin film. It is preferably composed of a laminated body.

Examples of the above-mentioned woven fabric or non-woven fiber material include natural fibers such as cotton, linen, silk and paper; semi-synthetic fibers such as rayon and acetate; nylon, vinylon, polyester, acrylic, polyethylene, polypropylene and polyvinyl chloride. , Polyester terephthalate, polybutylene terephthalate and other synthetic fibers; mixed fibers of these fibers can be exemplified. Among them, nylon, polyester, polypropylene, and polyethylene terephthalate can be preferably exemplified as the fiber material, and nylon, polyester, and polyethylene terephthalate can be more preferably exemplified as the fiber material from the viewpoint of improving the feel on the skin. These fiber materials may be used alone or in combination of two or more. The basis weight of the woven fabric or non-woven fabric is not particularly limited as long as it can prevent leakage of the heat-generating material 3 to the outside, but it may be, for example, about 20 g / m ² or more and 90 g / m ² or less. preferable.

Of the two sheet materials 27A and 27B, the first sheet material 27A on the side opposite to the side facing the face when the heater 1 is attached to the face has breathability. As the resin film constituting the first sheet material 27A, for example, a porous resin film or a resin film in which a plurality of perforations (not shown) are formed by needles is used in order to ensure air permeability, and a plurality of small resin films are used. Air communicates inside and outside the main body 2 through the holes. The plurality of small holes may be formed in the entire area of the resin film, or may be formed in a part of the area. The size of each small hole is not particularly limited as long as it can prevent the heat generating material 3 from leaking to the outside of the main body 2 through the small hole, and as an example, 0.1 μm or more and 30 μm or less is exemplified. Will be done. The shape and number of the small holes are not particularly limited, and the size, shape, and number of the small holes are appropriately set in consideration of the heat generation temperature of the heat generating material 3 at the time of use according to the air permeability of the main body 2. Will be done.

When the heating tool 1 is used for the purpose of warming the left and right eyes and the surroundings of each eye, the heat generation temperature is 30 ° C. or higher and 70 ° C. or lower, preferably 35 ° C. or higher and 60 ° C. or lower in an environment of 20 ° C. ( The temperature measurement method is preferably designed so as to be set in accordance with Japanese Industrial Standards S4100).

Of the two sheet materials 27A and 27B, the second sheet material 27B on the side facing the face when the heating device 1 is attached to the face has the same degree of air permeability as the first sheet material 27A. It may have poor breathability, which has a greater resistance to ventilation than the first sheet material 27A, or may be non-breathable, which does not allow air to pass substantially. When the resin film constituting the second sheet material 27B is non-breathable, a non-breathable resin film that is neither a porous film nor a perforation (not shown) is used.

The thickness of the two sheet materials 27A and 27B is not particularly limited, but is preferably about 0.1 mm or more and 2.0 mm or less. As a result, the main body 2 can be made soft and easily fit to the face, while the main body 2 can maintain a certain strength.

The two sheet materials 27A and 27B do not necessarily have to be composed of a laminate of a resin film and a woven fabric or a non-woven fabric, and may be composed of a single resin film or a single woven fabric or a non-woven fabric. It may be composed of.

Next, the pair of ear hooks 4L and 4R are hung on the left and right ears when the heater 1 is attached to the face. In the pair of ear hooks 4L and 4R, one ear hook 4L is provided at the left end of the main body 2, and the other ear hook 4R is provided at the right end of the main body 2.

When the pair of ear hooks 4L and 4R have elasticity, it is possible to easily hang the pair of ear hooks 4L and 4R on the ears when the heating device 1 is attached to the face. The pair of ear hooks 4L and 4R do not necessarily have to have elasticity, and may have a property of extending but weakly contracting or not contracting, or having a property of neither stretching nor contracting. Good.

The material of the pair of ear hooks 4L and 4R is not particularly limited, and examples thereof include a woven fabric, a non-woven fabric, and a resin film, and the pair of ear hooks 4L and 4R use these independently. Alternatively, a laminate obtained by combining a plurality of these may be used. As the fiber material of the woven fabric or the non-woven fabric, for example, natural fibers such as cotton, linen, silk and paper; semi-synthetic fibers such as rayon and acetate; nylon, vinylon, polyester, acrylic, polyethylene, polypropylene, polyvinyl chloride and poly. Synthetic fibers such as butylene terephthalate; mixed fibers of these fibers can be exemplified. These fiber materials may be used alone or in combination of two or more. The resin used for the resin film is not particularly limited, but is polyethylene, polypropylene, polyolefin, polyester, polyamide, polyurethane, polystyrene, polyvinyl alcohol, polyvinyl chloride, polyvinylidene chloride, polycarbonate, ethylene-vinyl acetate common weight. Coalescence and the like can be exemplified. These resins may be used alone or in combination of two or more.

The pair of ear hooks 4L and 4R are stacked on the main body 2 in the closed state before the heating tool 1 shown in FIG. 1 (B) is attached to the face. The pair of ear hooks 4L and 4R have the same outer shape as the left half and the right half of the main body 2 with the vertical center line 24 as the boundary, respectively, and the pair of ear hooks 4L and 4R have the same outer shape as the upper edge and the pair of ear hooks 4L and 4R. The lower edge is located (overlapping) on the upper edge 20 and the lower edge 21 of the main body 2, and one side edge of the pair of ear hooks 4L and 4R is the left and right side edges 22 and 23 of the main body 2. Positioned (overlapping) above, the other side edge of the pair of ear hooks 4L, 4R is positioned (overlapping) on the vertical center line 24 of the main body 2.

The pair of ear hooks 4L and 4R are attached to the lateral ends of the main body 2 by joining a part thereof to the corresponding lateral ends of the main body 2. The pair of ear hooks 4L and 4R have their outer ends (base ends) facing each other when the main body 2 is attached to the face in the closed state shown in FIG. 1 (B). (The surface of the second sheet material 27B). In this embodiment, heat welding (heat sealing) is used for joining the main body 2 and the pair of ear hooks 4L and 4R, but in addition to heat welding, for example, crimping using a known adhesive and ultrasonic waves.

As shown in FIGS. 1B and 5, each joint portion 5 extends along the vertical direction of the main body portion 2 with a predetermined lateral width at the left and right end portions of the main body portion 2. In the present embodiment, each joint portion 5 extends from the left and right side edges 22 and 23 of the main body portion 2 along the vertical direction of the main body portion 2 with a predetermined lateral width. Therefore, the outer contour line 50 of each joint portion 5 in the lateral direction of the main body portion 2 is located (overlapping) on the left and right side edges 22 and 23 of the main body portion 2.

The inner contour line 51 of the main body 2 of each joint 5 extends parallel to the vertical direction of the main body 2, but bends inward in the middle to reach the lower edge 21 of the main body 2. .. Therefore, a part (protruding portion 52) of each joint portion 5 protrudes inward on the lower end side. Specifically, in the present embodiment, the inner contour line 51 of each joint portion 5 extends downward from the upper edge 20 of the main body portion 2 in parallel with the vertical direction of the main body portion 2, and then is perpendicular to the inside. It is bent in the lateral direction of the main body 2) and extends further downward. Therefore, in the present embodiment, the inner contour line 51 of each joint portion 5 is continuous with the third portion 51C extending parallel to the vertical direction of the main body portion 2 from the upper edge 20 of the main body portion 2 and the third portion 51C. A second portion 51A that bends inward in the lateral direction of the main body 2 from a portion 51D that bends inward, and a second portion that is continuous with the first portion 51A and extends parallel to the lower edge 21 of the main body 2 in the vertical direction of the main body 2. Each joint portion 5 is composed of a portion 51B, and a part (protruding portion 52) including a lower end portion protrudes inward in each joint portion 5. The first portion 51A is orthogonal to the third portion 51C and extends parallel to the lateral direction of the main body portion 2.

It is more preferably 5 mm or more. The third portion 51C does not necessarily have to be parallel to the vertical direction of the main body portion 2, and may be slightly inclined inward or outward.

The inner contour line 51 of each joint portion 5 determines the deployment direction of the pair of ear hook portions 4L and 4R from the closed state. In the present embodiment, the inner contour line 51 of each joint portion 5 protrudes inward on the lower end side than on the upper end side. Therefore, as shown in FIGS. 3 and 5, when the pair of ear hook portions 4L and 4R are folded back and unfolded at each joint portion 5 from the closed state shown in FIG. 1 (B), the main body portion 2 Deploy in a shape that extends diagonally downward with respect to the lateral direction. Since the ears are slightly lower in position than the eyes, the pair of ear hooks 4L and 4R can be deployed diagonally downward so that the heater 1 can be worn on the user's face without discomfort.

Further, since the lower end side of the inner contour line 51 of each joint portion 5 protrudes inward from the upper end side, as shown in FIG. 6, a pair of ears are used to expand the pair of ear hook portions 4L and 4R. When the hanging portions 4L and 4R are pulled outward, the main body portion 2 has the lower regions of the left and right ends (around the lower left and right corners 25 and 26 of the main body portion 2) via the respective joint portions 5. It is pulled strongly. At this time, since the inner contour line 51 of each joint portion 5 bends inward in the middle and reaches the lower edge 21 of the main body portion 2, the main body portion 2 passes through each joint portion 5 of the inner contour line 51. Due to the bending, the area on the lower side of the left and right ends (around the lower left and right corners 25 and 26 of the main body 2) bends toward the user's face (the front side in the figure in FIG. 6). Deform. As a result, the lower left and right corners 25 and 26 of the main body 2 cover the cheekbones under the eyes when the heater 1 is attached to the face, and fit the face without rising from the face. Therefore, the main body 2 has improved adhesion to the face. As described above, in the present embodiment, by providing the inner contour line 51 of each joint portion 5 with the portion 51D that bends inward in the middle, the region below the left and right ends of the main body portion 2 (of the main body portion 2). It is possible to easily bend and deform the lower left and right corners (around 25 and 26) along the surface shape of the user's face. In the main body 2, the upper region of the left and right ends (around the upper left and right corners of the main body 2) is also a user's face due to the bending of the inner contour line 51 via each joint 5. It is deformed so as to bend to the side (the front side in the figure in FIG. 6). Therefore, the main body portion 2 fits the face without rising from the face even in the upper regions of the left and right end portions (around the upper left and right corners of the main body portion 2), and the adhesion to the face is improved.

As shown in FIGS. 1B and 3, openings 40 are formed in the pair of ear hooks 4L and 4R. The opening 40 is a portion into which the ear is inserted when the pair of ear hook portions 4L and 4R are hung on the user's ear. The opening 40 is formed horizontally so that the ear can be easily inserted into the opening 40. Further, the opening 40 has a vertical width (direction orthogonal to the longitudinal direction) from the base end side to the tip end side, that is, in the direction away from the main body 2 and toward the ear when the heating tool 1 is attached. The length) is formed so as to gradually expand. As a result, the ear can be easily inserted into the opening 40, and the fit of the pair of ear hooks 4L and 4R to the ear can be improved. The shape and size of the opening 40 are not particularly limited as long as the ear can be inserted into the opening 40.

Next, the method of using the above-mentioned heating tool 1 will be described. Since the heat generating material 3 generates heat in the presence of air, the heating tool 1 needs to be prevented from coming into contact with air before use, and is stored in an airtight packaging bag (not shown) that does not allow air to pass through. There is. At the time of use, the packaging bag is opened and the heating tool 1 is taken out. Then, the pair of ear hook portions 4L and 4R are expanded from the closed state, and the main body portion 2 is used by the user so that the second joint portions 29L and 29R (eye covering portions) of the main body portion 2 hit the left and right eyes of the user. The pair of ear hooks 4L and 4R are pulled outward and hung on the ears. As a result, the heat generated from the heat generating material 3 gives heat to the left and right eyes and around each eye.

When the heating tool 1 is attached to the face, the central portion of the lower edge 21 of the main body 2 in the horizontal direction is curved in a concave shape and is largely constricted. It folds in two and deforms along the shape of the face. Therefore, the main body 2 fits well on the user's face.

In addition, in the pair of ear hook portions 4L and 4R, at the joint portion 5 with the main body portion 2, the inner contour line 51 bends inward in the middle and reaches the lower edge 21 of the main body portion 2. As shown in, when the pair of ear hooks 4L and 4R are pulled laterally outward with respect to the main body 2 in order to hang the pair of ear hooks 4L and 4R on the ears, the area below the left and right ends of the main body 2 (main body). (Around the left and right corners 25 and 26 on the lower side of 2) are strongly pulled, and the main body 2 is deformed so as to be curved in the vertical direction and bent toward the user's face side (front side in the figure in FIG. 6). The left and right corners 25 and 26 on the lower side of the main body 2 hit the cheekbones under the eyes when the heater 1 is attached to the face, but even if the cheekbones are protruding, they bend along the surface shape. It covers the cheekbones and fits the face without rising from the face. Therefore, the main body 2 can be brought into close contact with the user's face with better fit, and the heat generated from the heat generating material 3 can be suppressed from escaping to the outside.

As described above, according to the heating tool 1 of the present embodiment, the main body 2 can be fitted to the user's face well, so that the heating effect of the heat generating material 3 can be effectively brought out, and the user can effectively bring out the heating effect. It can effectively apply heat to the eyes and the area around the eyes.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention.

As a modification, in the above embodiment, in each of the joints 5 of the pair of ear hooks 4L and 4R, the inner contour line 51 is formed by bending inward in the middle, and the portion 52 protruding inward (hereinafter, hereinafter, The "protruding portion 52") is formed in a continuous series without interruption, but as shown in FIG. 7, the protruding portion 52 of each joint portion 5 must be formed in a continuous series. However, it may be formed intermittently so as to be interrupted in the middle, and the protruding portion 52 of each joint portion 5 includes at least one separating portion 54 provided at intervals in the lateral direction of the main body portion 2. May be good. Although the left half of the heating tool 1 is not shown in FIG. 7, the configuration is the same as that of the right half.

In FIG. 7A, the protruding portion 52 of each joint portion 5 is spaced apart from the bent portion 53, which bends inward at the lower end of each joint portion 5, in the lateral direction of the main body portion 2. It is composed of two separating portions 54 provided in the above. Further, in FIG. 7B, the protruding portion 52 of each joint portion 5 is composed of three separation portions 54 provided at the lower end of each joint portion 5 at intervals in the lateral direction of the main body portion 2. There is.

In the present disclosure, the contour line of the joint portion 5 refers to a line forming around the overall outer shape of the joint portion 5, and even in the modified example of FIG. 7, the contour line 51 inside each joint portion 5 is used. As in the above embodiment (see FIG. 1 (B) and the like), after extending downward from the upper edge 20 of the main body 2 parallel to the vertical direction of the main body 2, it is perpendicular to the inside (main body 2). It bends in the horizontal direction) and extends further downward. The inner contour line 51 extends from the upper edge 20 of the main body 2 to the side of the main body 2 from the third portion 51C extending parallel to the vertical direction of the main body 2 and the portion 51D continuous with the third portion 51C and bending inward. It is composed of a first portion 51A extending parallel to the direction and a second portion 51B continuous with the first portion 51A and extending parallel to the vertical direction of the main body 2 from the lower edge 21 of the main body 2. The first portion 51A of the inner contour line 51 is represented by a line connecting the bent portion 53 and the upper edges of the two separating portions 54 in the modified example of FIG. 7 (A) from the portion 51D that bends inward. In the modified example of B), it is represented by a line connecting the upper edges of the three separating portions 54. In FIG. 7, the contour line 51 is shown at a position slightly deviated from the actual position of the contour line inside the joint portion 5 in order to make the contour line 51 easier to see.

The separation portion 54 has a predetermined width and extends parallel to the vertical direction of the main body portion 2 on the lower edge 21 side of the main body portion 2. The separating portion 54 is formed to have a length that does not reach the upper edge 20 of the main body portion 2, preferably a length that does not reach the center of the main body portion 2 in the vertical direction. The separation portion 54 may extend from the lower edge 21 of the main body portion 2 or may extend from a position separated by a predetermined distance from the lower edge 21 of the main body portion 2 in the vertical direction of the main body portion 2. Further, the separating portion 54 does not necessarily have to extend in parallel in the vertical direction as long as it is along the vertical direction of the main body portion 2, and may extend slightly inwardly or outwardly. Further, when a plurality of separating portions 54 are provided, the positions of the upper ends and the lower ends of the plurality of separating portions 54 may all be the same position or different positions in the lateral direction of the main body portion 2.

Also in the modified example of FIG. 7, in the pair of ear hook portions 4L and 4R, at the joint portion 5 with the main body portion 2, the inner contour line 51 bends inward in the middle and reaches the lower edge 21 of the main body portion 2. Therefore, when the pair of ear hooks 4L and 4R are pulled laterally outward with respect to the main body 2 in order to hang the pair of ear hooks 4L and 4R on the ears, the area below the left and right ends of the main body 2 (of the main body 2). The lower left and right corners (around 25 and 26) are pulled strongly and deformed so as to bend toward the user's face. The left and right corners 25 and 26 on the lower side of the main body 2 hit the cheekbones under the eyes when the heater 1 is attached to the face, but even if the cheekbones are protruding, they bend along the surface shape. It covers the cheekbones and fits the face without rising from the face. Therefore, the main body 2 can be brought into close contact with the user's face with better fit, and the heat generated from the heat generating material 3 can be suppressed from escaping to the outside.

In addition, at each joint portion 5, the angle 55 at which the first portion 51A and the second portion 51B of the inner contour line 51 intersect is provided on the main body portion 2 in order to hang the pair of ear hook portions 4L and 4R on the ears. On the other hand, when it is pulled outward in the lateral direction, it is the portion where the load is most applied, and if an excessive load is applied to the corner 55, the ear hook portions 4L and 4R may be cut at the corner 55. At this time, as in the above embodiment (see FIG. 1B and the like), if the upper edge of the protruding portion 52 of each joint portion 5 extends continuously in parallel with the lateral direction of the main body portion 2, the ear There is a possibility that the cuts of the hanging portions 4L and 4R will continuously spread from the corner 55 to the portion 51D that bends inward along the upper edge of the protruding portion 52. On the other hand, in the modified example of FIG. 7, since the upper edge of the protruding portion 52 of each joint portion 5 extends intermittently in parallel with the lateral direction of the main body portion 2, the ear hook portions 4L, 4R at the corner 55 Even if there is a break, the continuous cut of the ear hooks 4L and 4R stops once at a position where there is no upper edge of the protruding portion 52, and the cut of the ear hooks 4L and 4R bends inside each joint 5. It is possible to prevent the continuous spread to the portion 51D.

As another modification, in the above embodiment, at each joint portion 5 of the pair of ear hook portions 4L and 4R, the inner contour line 51 is bent inward at a right angle (parallel to the lateral direction of the main body portion 2) in the middle. However, as shown in FIGS. 8 and 9, if the inner contour line 51 is bent inward in the middle, it does not necessarily have to be bent at a right angle (parallel to the lateral direction of the main body 2). Although the left half of the heating tool 1 is not shown in FIGS. 8 and 9, the configuration is the same as that of the right half.

For example, in the modified example of FIG. 8A, each joint portion 5 of the pair of ear hook portions 4L and 4R is curved so that the inner contour line 51 becomes convex inward in the middle of the main body portion 2. It has reached the lower edge 21. As a result, a part (protruding portion 52) including the lower end portion of each joint portion 5 protrudes inward. In the modified example of FIG. 8A, the inner contour line 51 of each joint portion 5 has a third portion 51C extending parallel to the upper edge 20 of the main body portion 2 in the vertical direction of the main body portion 2 and a third portion 51C. It is composed of a first portion 51A that reaches the lower edge 21 of the main body 2 while being curved inward in the lateral direction from the portion 51D that is continuous and bends inward, and is continuous with the first portion 51A.

It is composed of a second portion 51B extending in parallel with the second portion 51B, but there is no second portion 51B, and the first portion 51A may reach the lower edge 21 of the main body portion 2 while bending diagonally downward.

Further, in the modified example of FIG. 9B, each joint portion 5 of the pair of ear hook portions 4L and 4R is bent in a staircase shape in which the inner contour line 51 has a plurality of steps toward the inside in the middle of the main body. It reaches the lower edge 21 of the portion 2. As a result, a part (protruding portion 52) including the lower end portion of each joint portion 5 protrudes inward. In the modified example of FIG. 9B, the inner contour line 51 of each joint portion 5 has a third portion 51C extending parallel to the upper edge 20 of the main body portion 2 in the vertical direction of the main body portion 2 and a third portion 51C. The first part 51A, which is continuous with the first part 51A and bends inward in a stepwise manner from the portion 51D in the lateral direction of the main body 2, and the vertical direction of the main body 2 from the lower edge 21 of the main body 2 which is continuous with the first part 51A. It is composed of a second portion 51B extending in parallel with the second portion 51B.

Further, as in the modified example of FIG. 9C, in each of the joint portions 5 of the pair of ear hook portions 4L and 4R, the inner contour line 51 is halfway and is oblique toward the inside with respect to the lateral direction of the main body portion 2. Although it reaches the lower edge 21 of the main body 2 while bending downward, a part of each joint 5 is branched, and the branched portion 52 may protrude inward. In the modified example of FIG. 9C, the inner contour line 51 of each joint portion 5 has a third portion 51C extending parallel to the upper edge 20 of the main body portion 2 in the vertical direction of the main body portion 2 and a third portion 51C. The first part 51A that bends diagonally downward in the lateral direction of the main body 2 from the portion 51D that is continuous with and bends inward, and the vertical direction of the main body 2 from the lower edge 21 of the main body 2 that is continuous with the first part 51A. It is composed of a second portion 51B extending in parallel with the second portion 51B, but there is no second portion 51B, and the first portion 51A may reach the lower edge 21 of the main body portion 2 while bending diagonally downward.

Also in the modified examples of FIGS. 8 and 9, in the pair of ear hook portions 4L and 4R, the inner contour line 51 is bent inward in the middle at the joint portion 5 with the main body portion 2, and the lower edge 21 of the main body portion 2 is formed. When the pair of ear hooks 4L and 4R are pulled laterally outward with respect to the main body 2 in order to hang the pair of ear hooks 4L and 4R on the ears, the area below the left and right ends of the main body 2 (main body). The left and right corners 25 and 26 on the lower side of the portion 2) are strongly pulled and deformed so as to bend toward the user's face side. The left and right corners 25 and 26 on the lower side of the main body 2 hit the cheekbones under the eyes when the heater 1 is attached to the face, but even if the cheekbones are protruding, they bend along the surface shape. It covers the cheekbones and fits the face without rising from the face. Therefore, the main body 2 can be brought into close contact with the user's face with better fit, and the heat generated from the heat generating material 3 can be suppressed from escaping to the outside.

In addition, also in the modified examples of FIGS. 8 and 9, when the pair of ear hook portions 4L and 4R are pulled laterally outward with respect to the main body portion 2 in order to hang the pair of ear hook portions 4L and 4R on the ears, each joint portion 5 is inside. The load is most applied to the predetermined portion 56 of the contour line 51, and if an excessive load is applied to the portion 56, the ear hook portions 4L and 4R may be cut at the portion 56. On the other hand, in the modified examples of FIGS. 8 and 9, the portion that bends inward of the inner contour line 51 of each joint portion 5 extends parallel to the lower edge 21 of the main body portion 2 in the vertical direction of the main body portion 2. Except for the portion, it intersects with the virtual line 57 parallel to the lateral direction of the main body portion 2, and the upper edge of the protruding portion 52 of each joint portion 5 does not extend parallel to the lateral direction of the main body portion 2. Therefore, in each joint portion 5, even if the ear hook portions 4L and 4R are cut at the predetermined portion 56 of the inner contour line 51, the ear hook portions 4L and 4R are cut in the lateral direction from the portion 56 to the main body portion 2. Since the upper edge of the protruding portion 52 is located above the outside of the portion 56, the upper edge of the protruding portion 52 becomes a wall, and the cuts of the ear hooks 4L and 4R are cut at the joints. It is suppressed that it spreads to the portion 51D that bends inward of 5. Therefore, it is possible to prevent the cuts of the ear hook portions 4L and 4R from continuously spreading from the cut portion 56 to the bent portion 51D inside each joint portion 5.

In order to effectively prevent the above-mentioned cuts of the ear hook portions 4L and 4R from continuously spreading to the portion 51D that bends inward of each joint portion 5, each joint as shown in FIG. 9B is formed. It is preferable that the first portion 51A of the contour line 51 inside the portion 5 is bent in a stepped manner. Further, when the pair of ear hook portions 4L and 4R are pulled laterally outward with respect to the main body portion 2 in order to hang the pair of ear hook portions 4L and 4R on the ears, the load applied to the predetermined portion 56 of the contour line 51 inside each of the joint portions 5 described above.

It may be formed intermittently, which is interrupted in the middle. In FIG. 10, the protruding portion 52 of each joint portion 5 includes at least one separating portion 54 provided at intervals in the lateral direction of the main body portion 2. In FIGS. 10A and 10B, the protruding portion 52 of each joint portion 5 is composed of three separation portions 54 provided at the lower end of each joint portion 5 at intervals in the lateral direction of the main body portion 2. ing. In FIG. 10C, a part of each joint portion 5 is branched inward, the branched portion forms a protruding portion 52, and the protruding portion 52 is displaced in the vertical direction of the main body portion 2. Moreover, it is composed of three separating portions 54 provided at intervals in the lateral direction of the main body portion 2. Although the left half of the heating tool 1 is not shown in FIG. 10, the configuration is the same as that of the right half.

Also in the modified example of FIG. 10, the contour line of the joint portion 5 refers to a line forming around the overall outer shape of the joint portion 5, and in FIG. 10 (A), the contour line 51 inside each joint portion 5. Is bent diagonally downward with respect to the lateral direction of the main body 2 toward the inside to reach the lower edge 21 of the main body 2, and the inner contour line 51 is from the upper edge 20 of the main body 2 to the main body. A third portion 51C extending parallel to the vertical direction of 2 and a first portion 51A and a first portion 51A that bend diagonally downward in the lateral direction of the main body 2 from a portion 51D that is continuous with the third portion 51C and bends inward. It is composed of a second portion 51B which is continuous with and extends parallel to the lower edge 21 of the main body portion 2 in the vertical direction of the main body portion 2. The first portion 51A of the inner contour line 51 is represented by a line connecting the upper edges of the three separation portions 54 from the inwardly curved portion 51D. In FIG. 10A, the inner contour line 51 may reach the lower edge 21 of the main body portion 2 while the first portion 51A is bent diagonally downward without the second portion 51B.

In the modified example of FIGS. 10B and 10C, the inner contour line 51 of each joint portion 5 is bent in a step shape having a plurality of steps toward the inside in the middle to reach the lower edge 21 of the main body portion 2. The inner contour line 51 extends from the upper edge 20 of the main body 2 to the third portion 51C extending parallel to the vertical direction of the main body 2 and from the portion 51D continuous with the third portion 51C and bending inward to the main body. It is composed of a first portion 51A that bends inward in the lateral direction in a stepwise manner, and a second portion 51B that is continuous with the first portion 51A and extends parallel to the lower edge 21 of the main body 2 in the vertical direction of the main body 2. To. The first portion 51A of the inner contour line 51 is represented by a line connecting the upper edge of the three separation portions 54 and the upper part of the inner side edge from the portion 51D that bends inward. Also in FIG. 10, in order to make the contour line 51 easier to see, the contour line 51 is shown at a position slightly deviated from the actual position of the contour line inside the joint portion 5.

In the modified example of FIG. 10, the same effect as that of the modified examples of FIGS. 8 and 9 is obtained. Further, in the modified example of FIG. 10, since the upper edge of the protruding portion 52 of each joint portion 5 is intermittent, even if the ear hook portions 4L and 4R are cut, the ear hook portion 4L is formed at each separation portion 54. It is possible to prevent the cuts of the ear hooks 4L and 4R from temporarily stopping and continuously spreading to the portion 51D where the cuts of the ear hooks 4L and 4R are bent inside the joints 5.

As another modification, in the above embodiment, the joint portion 5 of the pair of ear hook portions 4L and 4R has an inner contour line 51 bent inward in the middle to reach the lower edge 21 of the main body portion 2. , A part of the lower end side (protruding portion 52) protrudes inward, but as shown in FIGS. 11 and 12, the inner contour line 51 bends inward in the middle and reaches the upper edge 20 of the main body 2. As a result, a further part (protruding portion 58) on the upper end side may protrude inward. Although the left half of the heating tool 1 is not shown in FIGS. 11 and 12, the configuration is the same as that of the right half.
