However, because of the protruding cheekbones near the lower eyes of the face, the left and right corners covering the lower side of the body near the face cannot follow the face and float, and the heat generated by the self-heating material escapes to The exterior, etc., cannot effectively impart the warmth around the user's eyes. In the heating element of Patent Document 1, if the earhooks are expanded downwardly with respect to the lateral direction of the main body, the main body can be easily adhered to the face when worn. However, there is still improvement in Patent Document 1 for the aforementioned problems. room.

The present invention was developed to solve the aforementioned problems, and its object is to provide an eye mask-type heating element that can be worn well on the face. Means to solve the problem

The present invention relates to an eye mask type heating element that is worn on the face of a user. The heating element of the present invention is characterized by having: a heating material; a body part which accommodates the heating material and covers the left and right eyes and around each eye when worn; and a pair of ear hooks, which are hung on the ears when worn; One of the pair of ear hooks is provided at the left end of the main body, the other is provided at the right end of the main body, and each of the pair of ear hooks includes a part that is joined to the end corresponding to the main body. The joint part of the pair of ear hooks has a contour line on the inner side in the transverse direction of the main body part. After being bent inward halfway, it reaches the lower edge of the main body part, so a part of each joint part protrudes toward the inside.

In the heating element of the present invention, in each of the joints of the pair of ear hooks, the inwardly curved part that can constitute the inner contour line is composed of the following first and second parts: the first part is self-facing The inner bend is a part extending parallel to the lateral direction of the main body part; the second part is a part that is connected to the first part and extends parallel to the longitudinal direction orthogonal to the lateral direction of the main body part to reach the lower edge of the main body part.

In the heating element of the present invention, among the joint parts that can constitute the pair of ear hooks, except for the part extending in parallel from the lower edge of the body part and the longitudinal direction orthogonal to the transverse direction of the body part, the inner contour line is curved inward The part of is intersecting an imaginary line parallel to the lateral direction of the aforementioned main body.

For example, each joint of the pair of ear hooks may be configured such that the inner contour line becomes concave or convexly curved toward the inside in the middle.

Alternatively, each joint of the pair of ear hooks may be configured such that the inner contour line is bent toward the inside halfway so as to incline downward relative to the lateral direction of the main body.

Alternatively, the joint portions of the pair of ear hooks may be configured such that the inner contour line is bent toward the inner side in the middle to form a stepped shape with a plurality of height differences.

The warming element of the present invention may constitute a portion protruding toward the inside of each joint portion of the pair of ear hook portions, and at least one partition portion is provided at intervals in the lateral direction of the main body portion.

In the heating element of the present invention, the contour lines of the joint parts that can constitute the pair of ear hanging parts in the lateral middle and outer sides of the body part overlap with the left and right side edges of the body part.

In the heating element of the present invention, the aforementioned pair of ear hanging parts can be formed to be self-superposed on the aforementioned main body part, and the joint parts can be folded back and unfolded. Invention effect

In the heating element of the present invention, in the joining part of the pair of ear hanging parts and the body part, the inner contour line is bent toward the inner side to reach the lower edge of the body part in the middle. Therefore, according to the heating element of the present invention, when a pair of ear hooks are stretched laterally outward with respect to the main body in order to hang a pair of ear hooks on the ears of a user, the area under the left and right ends of the main body is strongly stretched, and The longitudinal curvature of the main body is deformed to bend toward the user's face, so the area under the left and right ends of the main body can be adhered to the face without floating from the face. Especially, when the area on the lower side of the left and right ends of the main body covers the vicinity of the cheekbones under the eyes, even if the cheekbones are protruding, they can bend along the surface shape and cover the vicinity of the cheekbones, so the main body can be adhered well. Close to the user's face.

The form used to implement the invention

Hereinafter, the embodiment of the eye mask type heating element (hereinafter, simply referred to as "the heating element") of the present invention will be described with reference to the drawings. The warming piece is used after being worn on the user's face. By providing warmth to the left and right eyes and around each eye, it can heal eye fatigue or relieve muscle stiffness around the eyes, which can give a relaxing effect. Furthermore, the eye circumference is the range from the upper eyelid to the lower eyelid in the vertical direction of the face, preferably from the eyebrows to the nose, and the horizontal middle of the face refers to the range from the head of the eye to the area between the eyes and ears.

As shown in Figures 1 to 5, the heating element 1 of this embodiment has: a heating material 3, a main body 2 containing the heating material 3, and a pair of ear hooks 4L, 4R provided at the left and right ends of the main body 2 . The heating element 1 hangs the ear hanging parts 4L, 4R on the ear parts of the corresponding sides of the left and right ears, so that the main body part 2 is worn on the face so as to cover the left and right eyes and around each eye. In addition, in the heating element 1, the heating material 3 accommodated in the main body 2 generates heat, so that the left and right eyes in contact with the main body 2 and the peripheries of each eye are given warmth. The heating element 1 is the same as, for example, a disposable heating bag, and uses the reaction heat generated by the heating material 3 along with the oxidation reaction as a heat source. Furthermore, the heating element 1 of the present invention is not limited to using the reaction heat generated by the heating material 3 as a heat source as the heat source, and may be, for example, microwave irradiation by a microwave oven or the like to make the heating material 3 have heat energy.

First, the heat generating material 3 may use a powdery material that generates heat by contact with air. The heating material 3 can be an example of a composition containing the following substances in an appropriate content. The foregoing substances are oxidizable metals, activated carbon, carbon black, and water-retaining agents (such as wood powder, vermiculite, diatomaceous earth, wave Laminated iron, silica gel, alumina, water-absorbent resin, etc.), metal salt (such as table salt, etc.) and water. The oxidizable metal is a metal that can generate oxidation reaction heat, and examples thereof include powders or fibers selected from one or more of iron, aluminum, zinc, manganese, magnesium, and calcium. Among them, iron powder is also preferred from the viewpoints of handling, safety, manufacturing cost, preservation and stability. The iron powder may be one or more selected from reduced iron powder and atomized iron powder as examples. The above-mentioned composition can use a known composition that is conventionally used in disposable warm packs.

Furthermore, the heat-generating material 3 may also use a material that does not generate heat by contact with air. For example, a material that generates heat by receiving microwave irradiation such as a microwave oven (for example, ceramic powder such as fat iron, etc.) may be used as the heat generating material 3.

Next, the main body part 2 covers the left and right eyes and around each eye when the heating element 1 is worn on the face. The main body 2 is flat and formed in a horizontally long shape when viewed from a plan view, and is formed to be large enough to cover the left and right eyes and the periphery of each eye. In a plan view, the main body 2 has an upper edge 20 and a lower edge 21 along the transverse direction, and left and right side edges 22, 23 along the longitudinal direction. , Is a symmetrical shape.

Furthermore, in the present disclosure, "horizontal" refers to the direction parallel to the left-right direction (the direction connecting the left and right ears) of the face when the heating element 1 is worn on the face in the main body 2, and "longitudinal" refers to the horizontal direction. In the other direction, the direction parallel to the upper and lower direction of the face (the direction connecting the forehead, nose, and chin) in the main body 2 when the heating element 1 is worn on the face. In this embodiment, the longitudinal direction of the main body 2 is the horizontal direction. "Inner side" refers to the side of the main body part 2 in the transverse direction of the center line 24, and "outside" means the side of the left and right side edges 22, 23 in the transverse direction of the main body part 2 opposite to the longitudinal center line 24. The "left-right direction" defines the left-right direction based on when the user faces the front after wearing the heating element 1 on the face. The definition of these directions does not limit the usage of the heating element 1.

Relative to the upper edge 20, the lower edge 21 is located below the eyes when the heating element 1 is worn on the face. Therefore, the lateral center portion has a concave shape in the middle to follow the shape of the nose. In addition, the lower edge 21 extends obliquely downward with respect to the lateral direction from the lower end of the concave portion toward the left and right ends, and the left and right corners 25, 26 on the lower side of the main body 2 greatly expand on the lower side. Thereby, the left and right corners 25, 26 on the lower side of the main body 2 will cover the vicinity of the cheekbones under the eyes when the heating element 1 is worn on the face. The left and right corners 25, 26 on the lower side of the main body 2 have a curvature in this embodiment, but they do not necessarily have a curvature. The left and right side edges 22, 23 are linear in this embodiment, but they may also be curved convexly curved toward the outside.

The main body 2 is formed in a bag shape, and has a storage space in which the heating material 3 can be sealed in a sealed manner. The main body 2 has two sheets 27A, 27B with the same shape on the front and back, and all parts along the outer periphery of the two sheets 27A, 27B are joined to form a bag shape. In this embodiment, the two sheets 27A, 27B are joined by thermal bonding (heat sealing), but in addition to thermal bonding, well-known methods such as pressure bonding using known adhesives, ultrasonic bonding, etc. can also be used. The method can also be a combination of these.

The width dimension of the first joining portion 28 to which the outer peripheral edges of the two sheets 27A and 27B are joined is not particularly limited, and may be an appropriate width dimension. In addition, the width dimension of the first joining portion 28 may be slightly the same over the entire circumference of the outer peripheral edge of the main body portion 2, or may be different as in this embodiment. In this embodiment, the first joining portion 28 is formed along the width dimension of the longitudinal edge portions of the left and right side edges 22, 23 of the main body portion 2, which is longer than the horizontal edge portions along the upper edge 20 and the lower edge 21 of the main body portion 2. The width is large. In addition, the first joining portion 28 is formed so that the width dimension of the longitudinal edge portions along the left and right side edges 22, 23 of the main body 2 becomes larger toward the upper and lower sides, and is formed to the left and right corners to the lower side of the main body 2. The 25 and 26 sections have the largest width dimension.

In addition to the first joining part 28, the main body part 2 is joined to a pair of second joining parts 29L, 29R with two sheets 27A, 27B. A pair of second joining parts 29L, 29R are arranged in the main body 2 and correspond to the positions of the left and right eyes when the heating element 1 is worn on the face. One of the second joining parts 29L corresponds to and covers the left eye when the heating element 1 is worn on the face, and the other second joining part 29R corresponds to and covers the right eye when the heating element 1 is worn on the face. Covers, respectively, in the main body 2 to become eye coverings.

The pair of second joining parts 29L, 29R (eye covering parts) are parts where the heat generating material 3 is not housed in this embodiment. A pair of second joining parts 29L, 29R (eye covering part) are separated from the part (peripheral covering part) of the main body 2 that covers the eye circumference, and restricts the heating material 3 contained in the adjacent surrounding covering part from moving to a pair The second joining parts 29L, 29R (eye covering parts). The pair of second joining parts 29L, 29R (eye covering parts) have a horizontally long oblong shape (including an ellipse), but their shape is not particularly limited as long as they can cover the eyes. For example, they may have a horizontally long rectangle or Diamond and so on.

Since the main body 2 does not contain the heat-generating material 3 in the pair of second joint parts 29L, 29R (eye covering parts), it is designed so that when the heating element 1 is worn on the face, the left and right eyes will not be accompanied by the heat-generating material 3 Excessive heating caused by high temperature heat. If the left and right eyes (eyeballs) are heated excessively with high temperature heat, there is a concern that the corneal protein will deteriorate due to heat. Therefore, in the present embodiment, it is prevented that the left and right eyes (eyeballs) are excessively heated when the heating element 1 is worn on the face.

If the filling rate of the heating material 3 of the eye covering part of the main body 2 is lower than that of the surrounding covering part, the heating material 3 can also be accommodated. From the viewpoint of ), it is preferable that the heat generating material 3 is not accommodated. Furthermore, the "filling rate" in the present disclosure refers to the ratio of the weight of the heat generating material 3 actually filled with respect to the weight of the largest heat generating material 3 that can be filled in the eye covering part and the surrounding covering part.

In addition, from the viewpoint of not overheating the left and right eyes (eyeballs) when the heating element 1 is worn on the face, the main body 2 can also be used for the left and right eyes when the heating element 1 is worn on the face. The covering part of the eye serves as a through hole. However, if the eye covering part is used as a through hole and the heating element 1 is used as an eye mask at bedtime, the main body part 2 cannot be used to shield external light, and the effect of the eye mask is lost. In addition, when the heating element 1 is worn on the face, the left and right eyes cannot be appropriately warmed, and the heat generated by the self-heating material 3 will escape from the through hole to the outside, so it cannot effectively impart the temperature around the eyes. Hot doubts. Therefore, as in the heating element 1 of the present embodiment, if the eye covering part of the main body 2 is the second joining part 29L, 29R, compared with the case where the eye covering part is a through hole, the effect of the eye mask can be achieved more effectively. In addition, when the warming element 1 is worn on the face, proper warmth can be imparted to the left and right eyes, and the temperature of the warmth imparted around the eyes can be prevented from excessively dropping, which is preferable.

The two sheets 27A, 27B constituting the main body 2 have flexibility to follow the shape of the face when the heating element 1 is worn on the face. The materials of the two sheets 27A, 27B are not particularly limited, but in consideration of strength and durability against heat generation of the heating material 3, it is preferable to use a resin film.

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

In addition, from the viewpoint of making the skin contact of the heating element 1 good, the two sheets 27A, 27B are preferably composed of a laminate that is on the side opposite to the side facing the heat generating material 3 of the resin film Laminated layers have air-permeable woven or non-woven fabrics.

Examples of the fiber materials of the woven or non-woven fabric include: natural fibers such as cotton, linen, silk, and paper; semi-synthetic fibers such as rayon and acetate; nylon, vinylon, polyester, acrylic, polyethylene, and polypropylene , Polyvinyl chloride, polyethylene terephthalate, polybutylene terephthalate and other synthetic fibers; blended fibers of these fibers, etc. Among them, from the viewpoint of good skin contact, fiber materials can be preferably exemplified such as nylon, polyester, polypropylene, polyethylene terephthalate, and more preferably exemplified such as nylon, Polyester, polyethylene terephthalate. These fiber materials may be used alone or in combination of two or more kinds. The size of the woven fabric or non-woven fabric is not particularly limited as long as it can prevent the heat generating material 3 from leaking from the outside of the main body portion 2, but is ^{preferably about 20 g/m 2} or more and 90 g/m ² or less.

Among the two sheets 27A and 27B, the first sheet 27A on the side opposite to the side facing the face when the heating element 1 is worn on the face has air permeability. In order to ensure the air permeability of the resin film constituting the first sheet 27A, for example, a porous resin film or a resin film formed with a large number of perforations (not shown) with needles is used. Many small holes can be formed in the entire area of the resin film or 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 may be 0.1 μm or more and 30 μm or less. The shape and number of the small holes are not particularly limited. The size, shape, and number of the small holes can be appropriately set after considering the air permeability of the main body 2 and the heating temperature of the heating material 3 during use.

Furthermore, when the heating element 1 is used for the purpose of heating the left and right eyes and around each eye, the heating temperature should be set to 30°C or more and 70°C or less in an environment of 20°C, and 35°C or more and 60°C or less should be set as Good (The temperature measurement method is based on the Japanese Industrial Standard S4100).

Among the two sheets 27A, 27B, the second sheet 27B on the side facing the face when the heating element 1 is worn on the face can have the same degree of air permeability as the first sheet 27A. It may have low air permeability, which has a greater resistance to air permeability than the first sheet 27A, or may have non-air permeability that does not allow air to pass substantially. If the resin film constituting the second sheet 27B is non-air-permeable, a non-porous film is used and a non-air-permeable resin film is not formed with perforations (not shown).

The thickness of the two sheets 27A, 27B is not particularly limited, but is preferably about 0.1 mm or more and 2.0 mm or less. Thereby, the main body 2 can be made soft and easy to fit on the face, and a certain strength can be maintained in the main body 2.

Furthermore, the two sheets 27A, 27B do not necessarily need to be composed of a laminate of a resin film and a woven fabric or non-woven fabric, and may be composed of a separate resin film or a separate woven fabric or non-woven fabric.

Then, a pair of ear hanging parts 4L, 4R are hung on the left and right ears when the heating element 1 is worn on the face. Among the pair of ear hook parts 4L, 4R, one ear hook part 4L is provided at the left end of the main body part 2, and the other ear hook part 4R is provided at the right end of the main body 2.

The pair of ear hooks 4L and 4R are composed of one sheet and are stretchable. The stretchability is preferably as follows: the stretched length of the lateral outer side of the main body 2 (that is, the stretched length from the main body 2 toward the ears when the warming element 1 is worn) is greater than the longitudinal direction of the main body 2 (that is, the same as the aforementioned self The stretched length of the direction perpendicular to the direction from the main body 2 is long. If the pair of ear hooks 4L, 4R are stretchable, the pair of ear hooks 4L, 4R can be easily hooked on the ears when the heating element 1 is worn on the face. Furthermore, the pair of ear hooks 4L, 4R does not necessarily have to be stretchable, and may also be stretchable but weakly contracted or unable to contract, or unable to stretch and contract.

The material of the pair of ear hooks 4L, 4R is not particularly limited. Examples include woven fabrics, non-woven fabrics, and resin films. The pair of ear hooks 4L, 4R can be used alone or in combination. The majority of the layered body. Examples of woven or non-woven fiber materials include natural fibers such as cotton, linen, silk, and paper; semi-synthetic fibers such as rayon and acetate; nylon, vinylon, polyester, acrylic, polyethylene, polypropylene, etc. Synthetic fibers such as polyvinyl chloride and polybutylene terephthalate; blended fibers of these fibers, etc. These fiber materials may be used alone or in combination of two or more kinds. The resin used in the resin film is not particularly limited, and examples include polyethylene, polypropylene, polyolefin, polyester, polyamide, polyurethane, polystyrene, polyvinyl alcohol, polyvinyl chloride, and polyvinyl chloride. Vinylidene chloride, polycarbonate, ethylene-ethyl acetate copolymer, etc. These resins may be used alone or in combination of two or more kinds.

In the closed state where the warming element 1 shown in FIG. 1(B) is worn in front of the face, a pair of ear hooks 4L and 4R are superimposed on the main body 2. A pair of ear hooks 4L, 4R respectively present the same shape on the left and right half bounded by the longitudinal center line 24 of the main body 2. The upper and lower edges of the pair of ear hooks 4L, 4R are located on the main body 2On the upper edge 20 and the lower edge 21 (overlapping), the side edges of a pair of ear hooks 4L, 4R are located on the left and right side edges 22, 23 of the main body 2 (overlapping), a pair of ear hooks 4L, The side edge of the other side of 4R is located on the longitudinal center line 24 of the main body 2 (overlapped).

The pair of ear hooks 4L, 4R are respectively connected to the lateral ends of the main body 2 by joining parts of them to the lateral ends of the main body 2 respectively. In the closed state as shown in Figure 1(B), the outer ends (base ends) of the pair of earhooks 4L and 4R are joined to the warming element 1 of the body 2 when worn to the face and face The surface (the surface of the second sheet 27B) on the side facing the part. The main body 2 and the pair of ear hooks 4L, 4R are joined by thermal bonding (heat sealing) in this embodiment, but in addition to thermal bonding, for example, crimping using known adhesives, ultrasonic bonding, etc. The well-known method can also be a combination of these.

A pair of ear hooks 4L, 4R are automatically superimposed on the main body 2 as shown in Fig. 1(B) to the state shown in Figs. 3, 5, and 13(A). The joints 5 of 2 are folded back and unfolded to be in a state where they can be placed on the ears.

As shown in FIG. 1(B) and FIG. 5, in the left and right ends of the main body 2, the joint portions 5 have a predetermined width and extend along the longitudinal direction of the main body 2. In this embodiment, the joint portions 5 extend from the left and right side edges 22, 23 of the main body 2 and extend along the longitudinal direction of the main body 2 with a predetermined width. Therefore, the contour line 50 of each joint 5 is located on the left and right side edges 22, 23 of the main body 2 (overlapped) in the lateral outer side of the main body 2.

The inner contour line 51 of each joint 5 in the transverse direction of the main body 2 extends parallel to the longitudinal direction of the main body 2, but is bent toward the inside in the middle and reaches the lower edge 21 of the main body 2. Therefore, a part (protruding part 52) of each joint 5 protrudes toward the inner side from the lower end side. Specifically, the inner contour line 51 of each joint 5 in this embodiment extends from the upper edge 20 of the main body 2 to the lower side parallel to the longitudinal direction of the main body 2, and then faces at right angles to the inner side (to the lateral direction of the main body 2). After bending in parallel), it extends to the lower side. Therefore, in this embodiment, the inner contour line 51 of each joint 5 is composed of a third portion 51C, a first portion 51A, and a second portion 51B. The first part 51A is connected to the third part 51C and is bent at the lateral inner side of the body part 2 from the inwardly bent part 51D. The second part 51B is connected to the first part 51A and extends from the body part 2. The lower edge 21 extends in parallel with the longitudinal direction of the main body portion 2, and each joint portion 5 includes a portion of the lower end portion (the protruding portion 52) that protrudes toward the inner side. The first portion 51A and the third portion 51C are orthogonal to each other, and extend parallel to the lateral direction of the main body 2. From the viewpoint of ensuring the bonding strength between the body part 2 and the ear hook parts 4L, 4R, the distance between the third part 51C and the left and right side edges 22, 23 of the body part 2 is preferably 3mm or more, and 5mm or more is more preferable . Furthermore, the third portion 51C does not necessarily have to be parallel to the longitudinal direction of the main body 2, and may be slightly inclined toward the inside or outside.

The inner contour line 51 of each joint 5 determines the expansion direction of the pair of ear hooks 4L, 4R from the closed state. In this embodiment, the lower end side of the inner contour line 51 of each joint 5 protrudes inwardly from the upper end side. Therefore, as shown in FIGS. 3 and 5, the pair of ear hooks 4L, 4R are expanded from the closed state shown in FIG. The form that extends obliquely downward is unfolded. Since the position of the ears is slightly lower than the eyes, if the pair of ear hooks 4L and 4R are spread out obliquely and downwards, the heating element 1 can be comfortably worn on the user's face.

In addition, the inner contour line 51 of each joint 5 is projected inward from the lower end side than the upper end side. Therefore, as shown in FIG. When the outer side is stretched, the main body portion 2 is strongly stretched via the area below the left and right end portions of the joint portions 5 (near the left and right corners 25, 26 on the lower side of the main body portion 2). At this time, since the inner contour line 51 of each joint part 5 is bent inward halfway and reaches the lower edge 21 of the main body part 2, the main body part 2 is deformed to the left and right due to the bending of the inner contour line 51 of each joint part 5 The ends, particularly the lower area (near the left and right corners 25, 26 on the lower side of the main body 2) are curved toward the user's face (the front side in the figure in FIG. 6). Thereby, the left and right corners 25, 26 on the lower side of the main body 2 cover the vicinity of the cheekbones under the eyes when the heating element 1 is worn on the face, and does not float from the face and adhere to the face. As a result, the adhesion between the main body 2 and the face is improved. In this way, in this embodiment, by providing the inward bend 51D in the middle of the inner contour line 51 of each joint 5, the area under the left and right ends of the main body 2 (the left and right corners 25 on the lower side of the main body 2) Near 26) is easy to bend and deform along the shape of the user's face. Furthermore, the upper areas of the left and right ends of the main body 2 (near the left and right corners on the upper side of the main body 2) are also deformed toward the face of the user due to the bending of the inner contour line 51 through the joints 5 (Figure 6 The front side of the figure in the middle) is curved. Therefore, the area above the left and right ends of the main body 2 (near the left and right corners on the upper side of the main body 2) does not float from the face to adhere to the face, and the adhesion to the face is improved.

As shown in FIG. 1(B) and FIG. 3, the opening 40 is formed in a pair of ear hook part 4L, 4R. The opening 40 is a part to be put into the ear when the pair of ear hooks 4L, 4R are hung on the ears of the user. The opening 40 is formed horizontally, whereby the ear can be easily inserted into the opening 40. In addition, the opening 40 is formed from the proximal side to the distal side, that is, when the heating element 1 is worn, the vertical width (length in the direction orthogonal to the longitudinal direction) gradually changes from the main body 2 toward the ears. Big. Thereby, the ear can be easily inserted into the opening 40, and the conformability of the pair of ear hooks 4L, 4R to the ear can be improved. Furthermore, as long as the ear can be inserted into the opening 40, the shape or size of the opening 40 is not particularly limited.

Next, the method of using the above-mentioned heating element 1 will be explained. Since the heating material 3 generates heat in the presence of air, it is necessary to prevent contact with the air before use, and store the heating element 1 in an airtight packaging bag (not shown) with no air circulation. At the time of use, take out the warming piece 1 after opening the packaging bag. In addition, the pair of ear hooks 4L, 4R are unfolded from the closed state, so that each of the second joint portions 29L, 29R (eye covering portion) of the main body 2 corresponds to the left and right eyes of the user to connect the main body 2 with the user. While touching the face, stretch the pair of ear hooks 4L and 4R toward the outside while hooking the ears. In this way, the heat emitted by the self-heating material 3 is used to impart warmth to the left and right eyes and around each eye.

When the heating element 1 is worn on the face, since the horizontal center of the lower edge 21 of the main body 2 is curved into a concave shape, and the middle is greatly concave, the main body 2 is easily placed on the vertical center line 24 of the horizontal center. Fold in half and deform along the shape of the face. Therefore, the main body 2 adheres to the user's face with good conformability.

In addition, in the joint 5 between the pair of ear hooks 4L, 4R and the main body 2, the inner contour line 51 is bent inward halfway and reaches the lower edge 21 of the main body 2, so as shown in FIG. When the main body 2 is stretched laterally outward to hang a pair of ear hooks 4L, 4R on the ears, the area under the left and right ends of the main body 2 (near the left and right corners 25, 26 on the lower side of the main body 2) is received With a strong pulling force, it is bent toward the longitudinal direction of the main body 2 and then deformed to bend toward the user's face side (the front side in the figure in FIG. 6). The left and right corners 25, 26 on the lower side of the main body 2 are equivalent to the cheekbones under the eyes when the heating element 1 is worn on the face. Even if the cheekbones protrude, they will be curved along the surface to cover the cheekbones. Nearby, you can stick to your face without lifting from your face. Therefore, the main body 2 can be made to adhere to the user's face more conformably, and the heat generated by the self-heating material 3 can be prevented from escaping to the outside.

As described above, according to the heating element 1 of the present embodiment, since the main body 2 can be well fitted to the user's face, the heating effect generated by the heating material 3 can be effectively guided, and the user can be effectively given The eyes or around the eyes are warm.

The embodiments of the present invention are described above, but the present invention is not limited by the foregoing embodiments, and various changes can be made without departing from the spirit of the present invention.

As a modified example, in each joint 5 of the pair of ear hooks 4L, 4R in the foregoing embodiment, the inner contour line 51 is bent inward to form a portion 52 (hereinafter, referred to as "convex The projecting portion 52".) is formed continuously and continuously, but as shown in FIG. The protruding portion 52 of the portion 5 may also include at least one partition portion 54 arranged at intervals in the lateral direction of the main body portion 2. Furthermore, although the drawing of the left half of the heating element 1 is omitted in FIG. 7, it has the same structure as the right half.

In FIG. 7(A), the protruding portion 52 of each joint 5 is composed of a bent portion 53 and two partitions 54. The bent portion 53 is continuously bent toward the inner side at the lower end of each joint 5, and the partition The portion 54 is provided at intervals from the bending portion 53 in the lateral direction of the main body portion 2. In addition, in FIG. 7(B), the protruding portion 52 of each joint 5 is composed of three partitions 54 which are arranged at intervals in the lateral direction of the main body 2 at the lower end of each joint 5 .

Furthermore, in the present disclosure, the contour line of the joint 5 refers to a line that forms the overall outer shape of the joint 5, and in the modification of FIG. 7, the inner contour 51 of each joint 5 is also the same as that of the previous embodiment (see FIG. 1 (B) etc.) The same, after extending from the upper edge 20 of the main body 2 to the lower side parallel to the longitudinal direction of the main body 2, bend at a right angle inward (parallel to the lateral direction of the main body 2) and further extend to the lower side. The inner contour line 51 is composed of a third portion 51C, a first portion 51A, and a second portion 51B. The third portion 51C extends from the upper edge 20 of the body portion 2 in parallel with the longitudinal direction of the body portion 2. The first portion 51A Connected to the third portion 51C and extending parallel to the lateral direction of the main body portion 2 from the inwardly bent portion 51D, the second portion 51B connected to the first portion 51A and parallel to the longitudinal direction of the main body portion 2 from the lower edge 21 of the main body portion 2地extended. The first portion 51A of the inner contour line 51 is bent from the inner side 51D, which is represented by a line connecting the upper edges of the bent portion 53 and the two partition portions 54 in the modification of Fig. 7(A), as shown in Fig. 7(B) In the modified example, the line connecting the upper edges of the three partitions 54 is shown. Furthermore, in FIG. 7, in order to easily recognize the contour line 51, the contour line 51 is shown at a position slightly shifted from the actual position of the inner contour line of the joint 5.

The partition 54 has a predetermined horizontal width and extends parallel to the longitudinal direction of the main body 2 on the side of the lower edge 21 of the main body 2. The partition 54 is formed to a length that does not reach the upper edge 20 of the main body 2, preferably a length that does not reach the longitudinal center of the main body 2. Furthermore, the partition 54 may extend from the lower edge 21 of the main body 2, or may extend from the lower edge 21 of the main body 2 at a position separated by a predetermined distance in the longitudinal direction of the main body 2. In addition, as long as the partition 54 is along the longitudinal direction of the main body 2, it does not necessarily extend parallel to the longitudinal direction, and it may extend more or less obliquely to the inside or the outside. In addition, in the case where a plurality of partitions 54 are provided, the positions of the upper and lower ends of the plurality of partitions 54 in the lateral direction of the main body 2 may be all at the same position, or may be at different positions.

In the modified example of FIG. 7, in the joint 5 between the pair of ear hooks 4L, 4R and the main body 2, the inner contour line 51 is bent inward halfway and reaches the lower edge 21 of the main body 2. 2 When the pair of ear hooks 4L, 4R are stretched laterally outward to hang the ear hooks, the lower areas of the left and right ends of the main body 2 (near the left and right corners 25, 26 on the lower side of the main body 2) are strongly strengthened Stretches and deforms to bend toward the user’s face. The left and right corners 25, 26 on the lower side of the main body 2 are equivalent to the cheekbones under the eyes when the heating element 1 is worn on the face. Even if the cheekbones protrude, they will be curved along the surface to cover the cheekbones. Nearby, you can stick to your face without lifting from your face. Therefore, the main body 2 can be made to adhere to the user's face more conformably, and the heat generated by the self-heating material 3 can be prevented from escaping to the outside.

In addition, in each joint 5, the corner 55 at which the first portion 51A and the second portion 51B of the inner contour line 51 intersect is stretched laterally outward with respect to the main body 2 to hang the pair of ear hooks 4L, 4R on The part that receives the most load between the ears, and if the corner 55 receives too much load, the ear hooks 4L, 4R may be broken at the corner 55. At this time, as in the foregoing embodiment (refer to FIG. 1(B), etc.), if the upper edge of the protruding portion 52 of each joining portion 5 extends continuously in parallel in the lateral direction of the main body portion 2, there are ear hook portions 4L, 4R The rupture starts at the corner 55 and continuously spreads along the upper edge of the protruding portion 52 to the inward bend 51D. In contrast to this, in the modification of FIG. 7, since the upper edge of the protruding portion 52 of each joint 5 extends in parallel and intermittently with the lateral direction of the main body 2, even if the ear hook 4L, 4R is formed at the corner 55 Fracture, the continuous fracture of the ear-hook parts 4L, 4R can still be temporarily stopped at the position without the upper edge of the protruding part 52, which can prevent the fracture of the ear-hook parts 4L, 4R from continuously spreading to the inward folding of each joint 5 The bend is 51D.

The second part 51B may also be omitted. The first part 51A is bent obliquely downward and reaches the lower edge 21 of the main body 2.

In the modified example of FIGS. 8 and 9, in the joint 5 between the pair of ear hooks 4L, 4R and the main body 2, the inner contour line 51 is bent inward halfway and reaches the lower edge 21 of the main body 2, so When the pair of ear hooks 4L, 4R are stretched laterally outward with respect to the main body 2 to hang on the ears, the area on the lower side of the left and right ends of the main body 2 (near the left and right corners 25, 26 on the lower side of the main body 2) ) Under strong pulling force, it deforms into a bend toward the user's face. The left and right corners 25, 26 on the lower side of the main body 2 are equivalent to the cheekbones under the eyes when the heating element 1 is worn on the face. Even if the cheekbones protrude, they will be curved along the surface to cover the cheekbones. Nearby, you can stick to your face without lifting from your face. Therefore, the main body 2 can be made to adhere to the user's face more conformably, and the heat generated by the self-heating material 3 can be prevented from escaping to the outside.

In addition, in the modified examples of FIGS. 8 and 9, when the pair of ear hooks 4L and 4R are hung on the ears by stretching laterally outward with respect to the main body 2, the inner contour line 51 of each joint 5 is predetermined The place 56 will receive the most load. If the place 56 receives too much load, there is a suspicion that the ear hooks 4L, 4R will break at the place 56. In contrast, in the modified examples of FIGS. 8 and 9, except for the portion extending from the lower edge 21 of the main body 2 in parallel with the longitudinal direction of the main body 2, the inner contour line 51 of each joint 5 is curved toward the inner side. The imaginary lines 57 that are parallel in the lateral direction of the main body 2 intersect, and the upper edges of the protruding portions 52 of the joint portions 5 do not extend parallel to the lateral direction of the main body 2. Therefore, in each joint 5, even if a break of the ear hooks 4L, 4R occurs at the predetermined position 56 of the inner contour line 51, the break of the ear hooks 4L, 4R will not be parallel to the lateral direction of the main body 2 from the position 56. Since the upper edge of the protruding part 52 is located above the outer side of the place 56, the upper edge of the protruding part 52 is used as a barrier to prevent the breakage of the ear hook parts 4L, 4R from spreading to the inward folding of the joint parts 5 The bend is 51D. Therefore, it is possible to prevent the breakage of the ear hooks 4L, 4R from spreading to the inwardly bent portion 51D of each joint 5 from the break 56 as a starting point.

Furthermore, in order to effectively prevent the breakage of the ear hooks 4L, 4R from continuously spreading to the inwardly bent portion 51D of each joint 5, the inner contour line 51 of each joint 5 as shown in FIG. 9(B) The first part 51A is preferably bent into a stepped shape.

In the modification of FIGS. 8 and 9, the protruding part 52 in each joint 5 of the pair of ear hook parts 4L, 4R does not necessarily need to be continuously formed, and may also be intermittently broken in the middle as shown in FIG. 10 form. In FIG. 10, the protruding portion 52 of each joining portion 5 includes at least one partition portion 54 provided at intervals in the lateral direction of the main body portion 2. In FIG. 10(A)(B), the protruding portion 52 of each joint 5 at the lower end of each joint 5 is constituted by three partitions 54 arranged at intervals in the lateral direction of the main body 2. In FIG. 10(C), a part of each joint 5 is branched toward the inner side, and the branched part becomes a protruding part 52. The protruding part 52 is displaced in the longitudinal direction of the main body 2 and is arranged at intervals in the lateral direction of the main body 2的三分部54 constituted. Furthermore, although the drawing of the left half of the heating element 1 is omitted in FIG. 10, it has the same structure as the right half.

The first portion 51A is connected to the third portion 51C and is bent from the inward bend 51D to be inclined downward toward the lateral inner side of the main body 2. The second portion 51B It is connected to the first portion 51A and extends from the lower edge 21 of the main body 2 in parallel with the longitudinal direction of the main body 2. The first portion 51A of the inner contour line 51 is curved from the inner side 51D to a line connecting the upper edges of the three partitions 54. The inner contour line 51 in FIG. 10(A) may not have the second portion 51B, and the first portion 51A is bent obliquely downward and reaches the lower edge 21 of the main body 2.

In the modified example of FIG. 10(B)(C), the inner contour line 51 of each joint 5 is bent inwardly into a step shape with a large number of height differences in the middle, and then reaches the lower edge 21 of the main body 2 and the inner contour line 51 It is composed of a third portion 51C, a first portion 51A, and a second portion 51B. The third portion 51C extends from the upper edge 20 of the body portion 2 in parallel with the longitudinal direction of the body portion 2. The first portion 51A and the third portion 51C is connected and is bent into a stepped shape at the lateral inner side of the body part 2 from the inwardly bent part 51D.

The first portion 51A of the inner contour line 51 is curved from the inner side 51D, and is represented by a line connecting the upper edge of the three partitions 54 and the upper inner side edge. In addition, in FIG. 10, in order to easily recognize the contour line 51, the contour line 51 is shown at a position slightly shifted from the actual position of the inner contour line of the joining portion 5.

The modification of FIG. 10 also exhibits the same effect as the modification of FIGS. 8 and 9. In addition, in the modification of FIG. 10, since the upper edge of the protruding portion 52 of each joint 5 is formed intermittently, even if the ear hook 4L, 4R breaks, the ear hook 4L, 4R can still be broken continuously. Temporarily stopping at each partition 54 can prevent the breakage of the ear hooks 4L and 4R from continuously spreading to the inner bending part 51D of each joint 5.

In terms of other modified examples, in the foregoing embodiment, each joint 5 of the pair of ear hooks 4L, 4R reaches the lower edge 21 of the main body 2 after the inner contour line 51 is bent inward halfway, as shown in Figs. 11 and 12 As shown, one part of the lower end side (the projecting part 52) protrudes toward the inside, but the inner contour line 51 can also be bent inward halfway to reach the upper edge 20 of the main body 2 so that the other part of the upper end side (the projecting part 58) Protruding toward the inside.
