  The present invention relates to a heating device that applies heat to a worn site.

  2. Description of the Related Art Conventionally, there has been known a heating tool that applies heat to, for example, eyes or around the eyes using a heating element that generates heat with an oxidation reaction of metal powder such as iron powder (see, for example, Patent Document 1). ). Specifically, this heating tool heats water by the heat generated by the heating element to make it steam, and supplies the steam to the eyes and around the eyes together with the heat.

Japanese Patent No. 3049707

However, in Patent Document 1, since the exothermic body contains, for example, salts, water, a water retention agent, a reaction accelerator and the like in addition to the metal powder, the degree of dispersion of the metal powder is non-uniform. As a result, the degree of progress of the oxidation reaction of the metal powder varies, and the temperature of heat generation becomes non-uniform. Furthermore, if the degree of dispersion of water in the heat generating body is not uniform, the amount and temperature of water vapor generated with the oxidation reaction of the metal powder will vary.
As described above, there is a problem that it becomes difficult to adjust the amount of water vapor generated and the temperature, and the usability is deteriorated.

  Then, the subject of this invention is providing the heating tool which can suppress the variation | change_quantity of the generation amount and temperature of water vapor | steam.

That is, by adjusting the heat capacity of the water vapor generator, even if a part of the water vapor generator is heated with the heat generation of the heat generator, the rapid temperature change of the part is suppressed and the water vapor is locally generated. Generation | occurrence | production can be suppressed and water vapor | steam can be generated uniformly from the said whole water vapor | steam generator. At this time, since the heating element has a surface temperature of 50 ° C. or lower in the heat generation state, the temperature of water vapor generated from the water vapor generator is also 50 ° C. or lower.

It is a figure for demonstrating the heat generating body of the main-body part of the heating tool for eyes of FIG. It is a figure for demonstrating the main-body part of the heating tool for eyes of the modification 1. FIG. It is a figure for demonstrating the main-body part of the heating tool for eyes of the modification 2. FIG.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. However, the scope of the invention is not limited to the illustrated examples.
FIG. 1 is a front view showing an eye heating device 100 according to an embodiment to which the present invention is applied. 2A and 2B are cross-sectional views of the eye heating device 100 taken along the line II-II in FIG. 1, and FIG. 2A shows heat generation and water vapor generated by the eye heating device 100. FIG. 2B shows a state in which heat generation and water vapor are generated by the eye heating device 100. FIG.

The eye heating tool 100 is a heating tool that is formed in an eye mask shape, for example, and covers the eyes E and E of the wearer H to apply heat. Specifically, as shown in FIGS. 1, 2 (a) and 2 (b), the eye heating device 100 is worn so as to cover the left and right eyes E and E of the wearer H during use. Two main body portions 1 and 1 and a pair of ear hook portions 2 and 2 that are hung on each ear of the wearer H.
In the present embodiment, the left-right direction connecting the left and right eyes E, E of the wearer H is the X direction, the one direction orthogonal to the X direction is the Y direction, and the direction orthogonal to both the X direction and the Y direction is Z. The direction. Note that the eye heating device 100 is generally used in a state where the front of the face is directed upward (see, for example, FIG. 2A) such that the wearer H is on his back, In the following description, it is assumed that the Z direction is substantially parallel to the vertical direction (gravity direction).
2 (a) and 2 (b) schematically show a state in which the eye heating device 100 is worn over the eyebrow H1 to the cheek H2 with the eyelid H3 of the wearer H closed. It represents.

Two main body parts 1 are provided in the X direction (left and right direction) so as to correspond to the left and right eyes E and E respectively. Each main body 1 has a length (width) in the X direction (left-right direction) and a length in the Y direction (direction extending from the eyebrows H1 to the cheek H2) sufficient to cover the eyes E during use. doing.
Specifically, each main body 1 includes a heating element 11, a steam generator 12 that generates steam with the heat generated by the heating element 11, and an exterior body 13 that covers the heating element 11 and the steam generator 12. It has.

As the heating element 11, for example, a structure that generates heat due to a phase transition of a predetermined solution L in a supercooled state or a structure that generates heat due to an oxidation reaction of a metal powder such as iron powder can be applied.
Hereinafter, an example of the heating element 11 that generates heat due to the phase transition of the predetermined solution L in the supercooled state will be described with reference to FIGS. 3 (a) and 3 (b).
FIG. 3A is a front view showing the heating element 11, and FIG. 3B is a cross-sectional view of the heating element 11 taken along line BB in FIG. 3A.

As shown in FIG. 3A and FIG. 3B, the heating element 11 includes a first storage portion 111 in which a predetermined solution L in a supercooled state that generates heat due to phase transition is stored, and a predetermined solution L. A second housing portion 112 in which a crystallization start portion P for starting crystallization is housed, and a partition portion 113 that holds the first housing portion 111 and the second housing portion 112 in a non-communication state are provided.
In addition, the heating element 11 includes first and second packaging members 11A and 11B having substantially the same shape, for example, and a predetermined position of the superimposed first and second packaging members 11A and 11B is a predetermined pressure bonding method (for example, , Heat sealing, etc.) to form the first housing part 111, the second housing part 112, and the partition part 113.

  The first and second packaging members 11A and 11B are formed of a predetermined material considering strength, durability, and the like. Examples of the material of the first and second packaging members 11A and 11B include films such as polyethylene (PE), low-density polyethylene (LDPE), polypropylene (PP), polyethylene terephthalate (PET), polyamide (PA), and the like. The laminated body which laminated | stacked the kind of film etc. are mentioned.

The first accommodating portion 111 and the partition portion 113 are formed by bonding the first and second packaging members 11A and 11B, which are overlapped in a predetermined direction (for example, the Z direction), in, for example, a substantially “B” shape. Is done.
That is, a predetermined solution L (which may be in a supercooled state or may be in a state before being supercooled) is disposed at a predetermined position on the first and second packaging members 11A and 11B. In this state, the first bonding portion 114 is formed by bonding the periphery thereof in a substantially “B” shape. Accordingly, the first accommodating portion 111 is configured inside the first bonding portion 114, and the partition portion 113 is configured by a part (for example, a portion on the eyebrow H1 side) of the first bonding portion 114. The
Thus, the 1st bonding part 114 is formed so that the circumference | surroundings of the 1st accommodating part 111 may be enclosed.

The first storage unit 111 has, for example, a substantially rectangular shape in plan view, and the first storage unit 111 stores a predetermined solution L in a supercooled state.
The predetermined solution L is an aqueous solution in which a predetermined salt is dissolved in water at a predetermined concentration. Specifically, the predetermined solution L is, for example, dissolved in a predetermined amount of water (by heating if necessary) so as to be in a supersaturated state, and is in a supercooled state. Is.
Here, as the predetermined salt, inorganic hydration such as anhydrous sodium acetate, sodium acetate trihydrate, sodium sulfate decahydrate, calcium chloride hexahydrate, sodium pyrophosphate decahydrate, barium hydroxide hexahydrate, etc. Examples thereof include a mixed salt of an inorganic hydrated salt in which the melting point is adjusted by blending a salt and other salts, paraffin, polyethylene glycol, fatty acid, and the like. Among these, sodium acetate trihydrate and sodium sulfate decahydrate are preferable.

For example, when sodium acetate trihydrate is in a supercooled state, for example, sodium acetate trihydrate and water are mixed and then heated to dissolve sodium acetate trihydrate, or sodium acetate trihydrate and water are mixed. It is necessary to dissolve sodium acetate trihydrate by heating after filling the container.
Alternatively, an anhydride or an aqueous solution of acetic acid and sodium hydroxide may be mixed and used. In this case, heat is generated by the neutralization reaction, so that the temperature of the mixture rises due to the heat and the sodium acetate is dissolved. It is considered that it can be handled in a liquid state without requiring heating.

The predetermined solution L may be added with an adjusting agent that adjusts the softness of the predetermined solution L in a crystallized state.
Examples of the regulator include monohydric alcohols such as ethanol, polyhydric alcohols such as glycerin and polyethylene glycol (PEG), polysaccharides such as fructose and cyclodextrin, and the like. These monohydric alcohols, polyhydric alcohols, and polysaccharides may be used individually as adjusting agents, or may be used in combination. That is, the adjusting agent may contain at least one of alcohol and polysaccharide.
Here, the alcohol has a smaller molecular weight than the polysaccharide and the molecular structure is not complicated, so that it is easy to become familiar with the predetermined salt and water contained in the predetermined solution L. Therefore, when it is necessary to maintain sufficient softness in the crystallized state, it is preferable to mainly use alcohol (particularly polyhydric alcohol), and to maintain a certain degree of hardness in the crystallized state. When necessary, it is preferable to use mainly polysaccharides.

Moreover, when adding a regulator to the predetermined solution L, it is preferable that the addition amount will be 5-20 [weight%].
If the lower limit is less than 5% by weight, sufficient softness cannot be maintained in a state in which the predetermined solution L is crystallized, and fit to a worn part (for example, an eye E part). This is because it gets worse. Further, if the upper limit exceeds 20 [wt%], the predetermined solution L cannot be sufficiently crystallized, and sufficient heat of solidification cannot be generated due to phase transition.

The partition portion 113 has a lower bonding strength than other portions of the first bonding portion 114.
That is, when the first and second packaging members 11 </ b> A and 11 </ b> B are bonded together by a predetermined pressure bonding method to form the first bonded portion 114, the partition portion 113 is the other portion of the first bonded portion 114. Is crimped at a low temperature. Thereby, the bonding strength of the partition portion 113 is lower than the bonding strength of other portions in the first bonding portion 114.

In addition, the bonding strength of the partition portion 113 is such that the partition portion 113 is peeled off by pressure applied from at least one of the first housing portion 111 and the second housing portion 112 (for example, the first housing portion 111). Is set to
That is, the partition part 113 partitions the first storage part 111 and the second storage part 112 when the eye heating device 100 is not in use, and is thereby stored in the first storage part 111. The predetermined solution L and the crystallization start part P stored in the second storage part 112 are held so as not to contact each other.
When the eye heating device 100 is used, at least one of the first housing portion 111 and the second housing portion 112 (for example, the first housing portion 111) is replaced with the other housing portion (for example, When the pressure is applied to the side of the second housing portion 112 and the like, the partition portion 113 is peeled off, and the inside of the first housing portion 111 and the inside of the second housing portion 112 (the crystallization start portion P of the crystallization start portion P). Existing space). As a result, the predetermined solution L stored in the first storage unit 111 and the crystallization start unit P stored in the second storage unit 112 are brought into contact with each other.
In addition, the user of the eye heating tool 100 is not limited to the wearer H of the eye heating tool 100, and may be an assistant who assists the use of the eye heating tool 100.

In addition, for example, the length (width) in the left-right direction of the partition part 113 is narrower as it is further away from the first housing part 111 toward the eyebrow H1. That is, the partition part 113 formed in a substantially trapezoidal shape in plan view is formed on the eyebrow H1 side of the first housing part 111 formed in a substantially rectangular shape in plan view. And the 2nd accommodating part 112 is formed so that the length (width | variety) of the left-right direction of the partition part 113 may adjoin the upper bottom part which is the narrowest.
Of the portion on the eyebrow H1 side in the first bonding portion 114, the portion other than the partition portion 113 has a higher bonding strength than the partition portion 113, like the other portions in the first bonding portion 114. Has been.
In addition, the shape of the partition part 113 is an example, is not restricted to this, It can change arbitrarily arbitrarily.

The second storage unit 112 stores a crystallization start unit P that starts crystallization of the predetermined solution L stored in the first storage unit 111.
The second housing portion 112 has a portion on the opposite side of the first housing portion 111 across the partition portion 113 in the first and second packaging members 11A and 11B overlapped in a predetermined direction (for example, the Z direction). It is formed by bonding by a predetermined pressure bonding method (for example, heat sealing). That is, the first and second packaging members 11 </ b> A and 11 </ b> B are bonded in a gate shape on the eyebrow H <b> 1 side with respect to the first housing portion 111 to form the second bonding portion 115. Specifically, the first and second packaging members 11A and 11B are attached to the second bonding portion 115 so as to be adjacent to the eyebrow H1 side portion (the portion including the partition portion 113) of the first bonding portion 114. Are combined. Thereby, the 2nd accommodating part 112 in which the crystallization start part P is accommodated inside the 2nd bonding part 115 is comprised.
Note that the bonding of the first bonding unit 114 and the second bonding unit 115 may be performed at the same timing or may be performed at different timings.

The crystallization start part P is, for example, a fine crystal obtained by crystallizing a predetermined solution L stored in the first storage part 111, and comes into contact with the predetermined solution L to crystallize the predetermined solution L. To start.
In addition, for example, a predetermined amount of fine crystals as the crystallization start portion P is attached to the inner surface of one of the first and second packaging members 11A and 11B (for example, the first packaging member). Yes. That is, by printing fine crystals on a predetermined position on the inner surface of one packaging member by a predetermined printing method such as gravure printing, flexographic printing, silk screen printing, etc., the inner surface of the one packaging member is Fine crystals are attached.
Here, the position where the fine crystal is printed on one of the packaging members is the position inside the second bonding portion 115, that is, the portion where the first and second packaging members 11A and 11B are bonded (first bonding). In the mating portion 114), the partition portion 113 is adjacent to the opposite side of the first housing portion 111.
Thus, the 2nd accommodating part 112 is provided in the edge part side (For example, the edge part side by the side of the eyebrow H1, etc.) of the main-body part 1. FIG.

Further, the heating element 11 is configured so that the surface temperature when the heat generation is caused by the phase transition of the supercooled predetermined solution L is 50 ° C. or less.
That is, when the crystallization start portion P and the predetermined solution L stored in the first storage portion 111 come into contact with each other, the crystallization of the predetermined solution L starts and the solidification heat is generated by the phase transition of the predetermined solution L. Will occur. The heating element 11 is configured so that the surface temperature at this time is 50 ° C. or less.
Here, the control of the surface temperature of the heating element 11 is performed, for example, by changing the type or thickness of the first packaging member 11A or the second packaging member 11B, or by a covering member such as a nonwoven fabric or paper covering the heating element 11. It can be performed by adding, changing the content of the predetermined salt in the predetermined solution L in the supercooled state stored in the first storage unit 111, or changing the addition amount of the adjusting agent.
Thus, the heating element 11 has a surface temperature of 50 ° C. or lower in the heat generation state.

  Even when the heating element is configured to generate heat with the oxidation reaction of the metal powder, it is necessary to configure it to have a surface temperature of 50 ° C. or lower in the heating state from the viewpoint of adjusting the temperature of the water vapor. There is. The surface temperature of the heating element can be controlled by, for example, adding a coating member such as a film, a nonwoven fabric, or paper covering the heating element, adjusting the thickness of the coating member, metal powder, salts, and reaction promotion in the heating element. It can be performed by adjusting various components such as an agent.

The steam generator 12 is disposed adjacent to the heating element 11 in the Z direction.
Specifically, the water vapor generator 12 is formed, for example, in a sheet shape having a shape substantially equal to the outer shape of the heating element 11, and is disposed on the skin side of the wearer H rather than the heating element 11. The one side of the skin of the wearer H and the one side opposite to the skin of the water vapor generating body 12 are in contact with each other.
Further, one surface of the water vapor generator 12 opposite to the heating element 11, that is, one surface on the skin side of the wearer H is arranged so as to cover the eyes E of the wearer H when the eye heating device 100 is used. It is installed. Here, the water vapor generator 12 functions as an eye cover that is disposed so as to cover the eye E of the wearer H when the eye heating device 100 is used, and the water vapor generator 12, the eye cover, Are integrally formed.

  Further, the water vapor generator 12 is in the form of a gel containing a large amount of water. Specifically, the water vapor generator 12 is, for example, a hydrated gel or non-woven fabric obtained by crosslinking polyacrylic acid, borax (1-2 wt.%) In a polyvinyl alcohol aqueous solution having a predetermined concentration (20-20%). %]) Is added to form a hydrous material or the like. Moreover, the water vapor generator 12 can adjust the heat capacity of the water vapor generator 12 by adjusting the amount of water and components.

Further, the outer surface of the water vapor generator 12 is covered with, for example, a breathable waterproof film having an appropriate air permeability and preventing moisture from leaking out.
This breathable waterproof film is formed by forming a melt-kneaded product of a thermoplastic resin such as polyethylene and fine particles (filler) such as calcium carbonate into a film shape and stretching it uniaxially or biaxially. It has a quality structure.

The water vapor generator 12 configured in this manner generates water vapor by evaporating the water in the water vapor generator 12 as the heat generating body 11 generates heat, and the eye E side (FIG. Water vapor is supplied in the direction indicated by the arrow in 2 (b) (see FIG. 2 (b)).
That is, the water vapor generator 12 is deformed as the internal pressure of the water vapor generator 12 increases with the generation of water vapor. Specifically, in a state where heat generation and water vapor are not generated by the eye heating device 100 (see FIG. 2A), one surface of the water vapor generator 12 on the eye E side of the wearer H and the wearer H A predetermined space is formed between the eye E and a portion around the eye E.
When water vapor is generated from the water vapor generator 12 as the heat generator 11 generates heat, the water vapor generator 12 expands a portion on the eye E side of the wearer H of the water vapor generator 12 according to the amount of water vapor generated. Deform to That is, it deform | transforms so that one surface of the wearer's H eyes E side of the water vapor generation body 12 may approach the wearer's H eyes E and the part around the eyes E. As a result, the water vapor generator 12 is deformed so as to correspond to the unevenness of the eyes E and the surrounding portions of the eyes E, and it becomes easy to fit the portions of the eyes E.
When the internal pressure of the water vapor generator 12 becomes larger than a predetermined value due to the generated water vapor, the water vapor leaks outside through the breathable waterproof film of the water vapor generator 12. Specifically, since the heating element 11 having a waterproof function exists on the side opposite to the skin of the wearer H of the steam generator 12, the steam generator 12 mainly has the side opposite to the heating element 11 (the wearer Water vapor leaks to the H skin side). In this way, water vapor is applied from the water vapor generator 12 to the eyes E which are the wearing sites of the wearer H.
The function of the exterior body 13 will be described later.

The exterior body 13 constitutes a covering that covers the heating element 11 and the water vapor generator 12 from the side opposite to the skin of the wearer H.
Specifically, the exterior body 13, for example, covers the steam generator 12 and the heating element 11 stacked in the Z direction from the side opposite to the skin of the wearer H of the heating element 11 and generates steam. The ends of the body 12 and the heating element 11 in the Y direction are covered so as to wrap around to a position where they can come into contact with the skin of the wearer H. In addition, although illustration is abbreviate | omitted, the exterior body 13 may coat | cover so that the edge part of the X direction of the water vapor | steam generator 12 and the heat generating body 11 may wrap around to the position which can contact the wearer's H skin.
Moreover, the exterior body 13 is comprised from the material which has a heat insulation function and a waterproof function, for example, films, such as PE, PP, PET, nylon, or these film materials are made into a bag shape and air is enclosed in it. And a laminate in which a foamed urethane sheet or a pulp sheet is laminated on a film material. Therefore, the heat generated from the heating element 11 is transmitted to the steam generator 12 side without being released outside (for example, the side opposite to the skin of the wearer H) by the exterior body 13 having a heat insulating function. In addition, the water vapor generated from the water vapor generator 12 is supplied to the skin side of the wearer H by the exterior body 13 and the heating element 11 having a waterproof function (see FIG. 2B). .

Each of the pair of ear hooks 2, 2 is provided continuously on both side portions of each main body 1 in the left-right direction (X direction).
Moreover, the ear hook part 2 is comprised from the raw material which has a stretching property, and is specifically comprised from the nonwoven fabric, the woven fabric, paper, the resin film etc., for example.

  Next, the application of the heat and water vapor from the eye heating device 100 to the wearer's H wearing part (the part of the eye E) will be described with reference to FIGS. 2 (a) and 2 (b).

First, when using the heating device for eyes 100, each main body 1 is worn so as to cover each of the left and right eyes E and E of the wearer H, and a pair of ear hooks 2 and 2 are worn by the wearer H. It is put on the ear (see FIG. 1).
In this state, the first storage portion 111 and the second storage portion 112 of the heating element 11 are partitioned by the partition portion 113, and are stored in the predetermined solution L stored in the first storage portion 111 and the second storage portion 112. The predetermined solution L is in a liquid state and does not generate heat because it does not come into contact with the crystallization start part P. Moreover, since water | moisture content is hold | maintained in the water vapor | steam generator 12, ie, it has not expanded | swelled by generation | occurrence | production of water vapor | steam, the one surface of the wearer's H eye E side of the said water vapor | steam generator 12, and the eyes E and eyes E of the wearer H A predetermined space is formed between the surrounding portions (see FIG. 2A).

Next, of the first storage unit 111 and the second storage unit 112, for example, when the first storage unit 111 is pressurized by the user toward the second storage unit 112, the partition unit 113 is peeled off, The inside of the 1st accommodating part 111 and the inner side of the 2nd accommodating part 112 will be in a communication state. And when the predetermined solution L accommodated in the 1st accommodating part 111 and the crystallization start part P accommodated in the 2nd accommodating part 112 contact | connect, the crystallization of the said predetermined solution L will start. Further, when the predetermined solution L undergoes phase transition, heat of solidification is generated and the heating element 11 generates heat.
When the heat generated by the heat generator 11 is transmitted to the water vapor generator 12, the water in the water vapor generator 12 evaporates to generate water vapor. The steam generator 12 is deformed so that the internal pressure of the steam generator 12 increases as the steam is generated, and the portion of the steam generator 12 on the eye E side of the wearer H expands according to the amount of steam. To do. Thereby, the surface of the wearer H on the eye E side of the water vapor generator 12 approaches the eye E of the wearer H or a portion around the eye E, and the water vapor generator 12 is placed around the eye E or around the eye E. It deform | transforms so that it may correspond to the unevenness | corrugation of a part, and it fits the part of the said eye E. FIG.
At this time, since the surface other than the one on the skin side of the wearer H of the water vapor generator 12 is covered with the exterior body 13 and the heating element 11 having a waterproof function, the water vapor generated from the water vapor generator 12 is Then, it leaks through the breathable waterproof film to the eye E side (the direction indicated by the arrow in FIG. 2 (b)), which is the wearing site of the wearer H (see FIG. 2 (b)).
In other words, the water vapor leaked from the water vapor generator 12 is applied to the eye E in a state where the water vapor generator 12 is fitted to the eye E.

As described above, according to the eye heating device 100 of the present embodiment, the heating element 11 is disposed adjacent to the heating element 11 having a surface temperature of 50 ° C. or less in the heating state, and the heating element 11 generates heat. Since the water vapor generator 12 that generates water vapor is provided, it is possible to evenly apply water vapor having a temperature of 50 ° C. or less from the water vapor generator 12 to the wearer's wearing site without being influenced by the heat generation state of the heat generator 11. it can. That is, by adjusting the heat capacity of the water vapor generator 12, even if a part of the water vapor generator 12 is heated with the heat generation of the heat generator 11, the rapid temperature change of the part is suppressed and the water vapor is generated. It can suppress generating locally and can generate | occur | produce water vapor | steam uniformly from the said water vapor | steam generator 12 whole. At this time, since the heating element 11 has a surface temperature of 50 ° C. or lower in the heat generation state, the temperature of the water vapor generated from the water vapor generator 12 is also 50 ° C. or lower. In particular, since the heating element 11 and the water vapor generator 12 are arranged so that their one surfaces are in contact with each other, the heat generated by the heat generating element 11 can be efficiently transmitted to the water vapor generator 12, and the water vapor generation Water vapor having a temperature of 50 ° C. or less can be efficiently generated from the body 12.
Therefore, by providing the heating element 11 and the steam generator 12 as separate bodies, the amount of steam generated and the temperature can be easily adjusted as compared with the heating element 11 containing water on the inside. Variation in generation amount and temperature can be suppressed.

  Moreover, since the water vapor | steam generator 12 is formed in the sheet form, and is arrange | positioned by the wearer's H skin side rather than the heat generating body 11, the water vapor | steam generate | occur | produced from the whole surface of the said water vapor | steam generator 12 which makes | forms a sheet form. It can be uniformly applied to the wearer's skin wearing site.

  Moreover, since the exterior body 13 having a heat insulating function and a waterproof function coats the heating element 11 and the water vapor generator 12 from the side opposite to the skin of the wearer H, it is 50 ° C. or less generated from the water vapor generator 12. It is difficult to supply water vapor at a temperature opposite to the skin of the wearer H, and the heat and water vapor generated from the eye heating device 100 are efficiently applied to the portion of the eye E that is the wear site of the wearer H. be able to.

  Further, the steam generator 12 is disposed as an eye covering portion so as to cover the eyes E of the wearer H when the eye heating device 100 is used, and the internal pressure is increased by the steam generated from the steam generator 12. Therefore, by generating water vapor from the water vapor generator 12 by the heat generation of the heat generator 11, the water vapor generator 12 can be deformed so as to correspond to the uneven shape of the portion of the eye E. Accordingly, it is possible to improve the fit of the eye heating tool 100 to the uneven eye E portion.

Further, since the portion of the eye H side of the wearer H of the water vapor generator 12 is deformed according to the amount of the generated water vapor, the eye heating tool 100 is worn on the eye E of the wearer H. In this state, even if there is a gap between the eye E of the wearer H or a portion around the eye E and one surface of the water vapor generator 12 on the eye E side of the wearer H, the gap It can be filled with the steam generator 12 which deform | transforms so that the part by the side of eyes E of the wearer H may expand | swell, and the fitting property of the said heating tool 100 for eyes with respect to the part of the eyes E with an unevenness | corrugation can be improved.
In particular, the water vapor generator 12 is configured to vent the outside of the water vapor generator 12 when the internal pressure of the water vapor generator 12 exceeds a predetermined value due to the generated water vapor. The water vapor leaked to the eye E side of the wearer H can be applied to the eye E of the wearer H.

  In addition, when the heating element 11 is configured to generate heat due to the phase transition of the supercooled predetermined solution L, the oxidation reaction proceeds like the heating element 11 that generates heat accompanying the oxidation reaction of the metal powder. The temperature of the heat generation does not become non-uniform due to the variation that occurs according to the degree, and the entire heat generator 11 can generate heat uniformly and be transmitted to the adjacent water vapor generator 12. Further, by adding an adjusting agent for adjusting the softness in a state where the predetermined solution L is crystallized to the predetermined solution L, the softness is maintained in a state where the predetermined solution L is crystallized. It is possible to improve the fit when the eye heating device 100 is worn on the eye E of the wearer H.

  In the above embodiment, the steam generator 12 is exemplified by a configuration that is deformed by the generated steam. However, the configuration is not limited to this, and the configuration of the steam generator 12 is arbitrarily changed as appropriate. Is possible. That is, in a state where the eye heating device 100 is worn on a predetermined wearing site of the wearer H, there is a gap between the predetermined wearing site of the wearer H and one surface on the skin side of the wearer H of the water vapor generator 12. When it does not occur, it is considered that the eye heating device 100 is sufficiently fitted to the wearing site of the wearer H, and therefore it is not necessary to have a configuration in which the water vapor generator 12 is deformed by water vapor.

  Moreover, in the said embodiment, although what comprised the heat insulation function and the waterproof function was illustrated as the exterior body 13, it is an example and is not restricted to this, The structure of the exterior body 13 can be changed arbitrarily arbitrarily. is there. That is, the exterior body 13 may be configured to have at least one of a heat insulating function and a waterproof function.

The present invention is not limited to the above-described embodiment, and various improvements and design changes may be made without departing from the spirit of the present invention.
Below, the modification of each structure of the heating element 100 for eyes which concerns on this invention is demonstrated. Note that points other than those described below are substantially the same as those in the above embodiment, and detailed descriptions thereof are omitted.

<Modification 1>
FIG. 4 is a view for explaining the main body 201 of the eye heating device 100 of the first modification, and is a cross-sectional view of the main body 201 at a position substantially equal to the line II-II in FIG.
As shown in FIG. 4, the main body 201 is provided with a heating element 211 disposed on the skin side of the wearer H with respect to the water vapor generator 12.

Specifically, the heating element 211 is formed in a smaller area than one surface on the skin side of the water vapor generator 12. In addition, one surface of the heating element 211 opposite to the skin of the wearer H and one surface of the water vapor generating body 12 are in contact with each other. That is, the heating element 211 has a shorter length in the Y direction than the steam generator 12, and the Y of the steam generator 12 is located outside both ends of the heating element 211 in the Y direction (upper and lower sides in FIG. 4). Both ends of the direction are arranged.
Although not shown, the heating element 211 has a length in the X direction that is shorter than that of the steam generator 12, and the X direction of the steam generator 12 is outside of both ends of the heating element 211 in the X direction. Both ends may be arranged.
Moreover, since the heating element 211 contacts the skin of the wearer H, from the viewpoint of improving the fit of the eye heating device 100, the supercooled predetermined solution L to which an adjusting agent for adjusting the softness is added. A heating element configured to generate heat by this phase transition is desirable.

Moreover, the exterior body 13 of the main body 201 covers the end portions in the Y direction of the water vapor generator 12 and the heat generator 211 so as to wrap around to a position where the skin of the wearer H can be contacted, as in the above embodiment. Yes.
Here, a predetermined space is formed between the outer end portion of the heating element 211 in the Y direction and the inner surface of the exterior body 13 in the Y direction, and the predetermined space is generated from the water vapor generator 12. It constitutes a water vapor channel. That is, the water vapor generated from the water vapor generator 12 is supplied to the skin side of the wearer H (in the direction indicated by the arrow in FIG. 4) via a predetermined space along the inner surface of the exterior body 13. It has become.
Although not shown, a predetermined space is also formed between the outer end portion of the heating element 211 in the X direction and the inner surface of the exterior body 13 in the X direction, and the predetermined space is a water vapor generator. The flow path of the water vapor generated from 12 may be configured.

Therefore, according to the eye heating device 100 of the first modification, even if the heating element 211 is disposed on the skin side of the wearer H with respect to the water vapor generator 12, the surface temperature of the heating element 211 is concerned. Is 50 ° C. or lower in a heat generation state, and excessively high temperature heat is not transmitted to the skin of the wearer H. Furthermore, since the exterior body 13 having a heat insulating function and a waterproof function covers the heating element 211 and the steam generator 12 from the side opposite to the skin of the wearer H, the heating element 11 is more than the steam generator 12. Even if it is disposed on the skin side of the wearer H, water vapor generated at a temperature of 50 ° C. or less generated from the water vapor generator 12 is unlikely to be supplied to the side opposite to the skin of the wearer H. It will be supplied to the skin side of the wearer H along the inner surface. In particular, heat generated from the side opposite to the skin of the wearer H of the heating element 211 can be transmitted to the water vapor generator 12, and the heat generated from the skin side of the wearer H of the heating element 211 is transmitted to the skin side of the wearer H. The heat generated by the heating element 211 can be used efficiently, and the time during which the heat can be applied by the eye heating device 100 can be extended.
Therefore, the heat and water vapor | steam which generate | occur | produced from the said heating tool 100 for eyes can be provided efficiently to the part of the eyes E which are the wearer's H wear part.

<Modification 2>
FIGS. 5A to 5C are views for explaining the main body 301 of the eye heating device 100 according to the second modification.
Among these, FIG. 5A and FIG. 5B are cross-sectional views of the main body 301 at a position substantially equal to the line II-II in FIG. 1, and FIG. FIG. 5B shows a state in which heat generation and water vapor are generated by the eye heating device 100. FIG. FIG. 5C is an enlarged view of a region A surrounded by a one-dot chain line in FIG.
As shown in FIGS. 5 (a) to 5 (c), in addition to the heat generator 211 and the water vapor generator 12, the main body 301 includes the eyes of the wearer H when the eye heating device 100 is used. An eye covering 14 disposed so as to cover E is provided, and water vapor generated from the water vapor generating body 12 through the eye covering 14 is applied to a portion of the eye E of the wearer H.

The eye cover 14 is disposed away from the water vapor generator 12. That is, in the said embodiment, although the water vapor | steam generator 12 was comprised integrally with the eye cover part, in the said modification 2, the water vapor generator 12 and the eye cover 14 are comprised separately. Yes.
Specifically, in substantially the same manner as in the first modification, the heating element 211 is disposed on the skin side of the wearer H with respect to the water vapor generation body 12, and the eyes are covered on the skin side of the wearer H with respect to the heating element 211. A body 14 is disposed. The eye cover 14 is formed in a larger area than one surface on the skin side of the heating element 211. In addition, one surface of the eye cover 14 opposite to the skin of the wearer H and one surface of the heating element 211 on the skin side are in contact with each other. That is, the heating element 211 has a shorter length in the Y direction than the eye cover 14, and covers the outer side of the heating element 211 at both ends in the Y direction (upper and lower sides in FIG. 5A, etc.). Both ends of the body 14 in the Y direction are arranged.
Although not shown, the heating element 211 has a length in the X direction that is shorter than that of the eye cover 14, and the X direction of the eye covering body 14 extends outside both ends of the X direction of the heating element 211. Both ends may be arranged.

The eye cover 14 is formed of, for example, a breathable waterproof film that has an appropriate air permeability and prevents moisture from leaking out.
This breathable waterproof film is formed by forming a melt-kneaded product of a thermoplastic resin such as polyethylene and fine particles (filler) such as calcium carbonate into a film shape and stretching it uniaxially or biaxially. It has a quality structure.

The end portion of the eye cover 14 is covered with an exterior body 313. That is, the exterior body 313 covers the Y-direction end portions of the water vapor generator 12, the heating element 211, and the eye cover 14 so as to go around to the position where the skin of the wearer H can be contacted.
Here, a predetermined space is formed between the outer end portion of the heating element 211 in the Y direction and the inner surface of the exterior body 313 in the Y direction, and the predetermined space is generated from the water vapor generator 12. It constitutes a water vapor channel. That is, the water vapor generated from the water vapor generator 12 is supplied to the eye cover 14 side (in the direction indicated by the curved arrow in FIG. 5C) via a predetermined space along the inner surface of the outer package 313. It has come to be.
Although not shown, a predetermined space is also formed between the outer end portion of the heating element 211 in the X direction and the inner surface of the exterior body 313 in the X direction, and the predetermined space is a water vapor generator. The flow path of the water vapor generated from 12 may be configured.

When the water vapor generated from the water vapor generator 12 is supplied to the eye cover body 14 configured in this way, the eye cover side portion of the wearer H of the eye cover body 14 according to the amount of water vapor supplied. Deforms to expand.
That is, the eye cover 14 is deformed due to an increase in internal pressure caused by water vapor generated from the water vapor generator 12. Specifically, in a state where no heat is generated and no water vapor is generated by the eye heating device 100 (see FIG. 5A), the eye E side of the wearer H of the eye cover 14 and the wearer H A predetermined space is formed between the eye E and a portion around the eye E.
When water vapor is generated from the water vapor generator 12 and supplied to the eye cover 14 with the heat generation of the heat generator 211 (see FIG. 5C, etc.), the eye cover 14 is adjusted to the amount of the supplied water vapor. Accordingly, the eye covering body 14 is deformed so that the portion of the eye H side of the wearer H expands. That is, it deform | transforms so that one surface of the wearer's H eye E side of the eye cover 14 may approach the wearer's H eye E and the part around the eye E. FIG. Thereby, the eye covering body 14 is deformed so as to correspond to the unevenness of the eye E and the surrounding portion of the eye E, and it becomes easy to fit the eye E portion.
When the internal pressure of the eye cover 14 becomes larger than a predetermined value due to the supplied water vapor, the water vapor leaks to the outside through the breathable waterproof film of the eye cover 14. Specifically, a heating element 211 having a waterproof function exists on the side of the eye cover 14 opposite to the skin of the wearer H, and the end side of the eye cover 14 is covered with an exterior body 313. Therefore, water vapor leaks from the eye covering 14 on the side opposite to the heating element 211 (the skin side of the wearer H; the direction indicated by the straight arrows in FIGS. 5B and 5C). (See FIG. 5B and FIG. 5C).
That is, in a state where the eye cover 14 is fitted to the eye E part, the water vapor leaked from the eye cover 14 is applied to the eye E part.

Therefore, according to the eye heating device 100 of the second modified example, the eye covering 14 disposed separately from the water vapor generator 12 corresponds to the amount of water vapor generated and supplied from the water vapor generator 12. Since the eye E side portion of the wearer H of the eye covering 14 is deformed so as to expand, the eye of the wearer H can be worn with the eye heating tool 100 worn on the eye E of the wearer H. Even if there is a gap between the E or the surrounding part of the eye E and one surface of the wearer H of the eye cover 14 on the side of the eye E, the part on the eye E side of the wearer H It can be filled with the eye covering 14 that is deformed so as to expand, and the fit of the eye heating tool 100 to the uneven eye E can be improved.
Further, heat generated from the side opposite to the skin of the wearer H of the heating element 211 can be transmitted to the water vapor generating body 12, and the heat generated from the skin side of the wearer H of the heating element 211 is worn by the eye cover 14. This can be transmitted to the skin side of the person H, the heat generated by the heating element 211 can be used efficiently, and the time during which the heat can be applied by the eye heating device 100 can be extended.

  In the second modification, the heating element 211 is disposed on the skin side of the wearer H with respect to the water vapor generator 12, but this is only an example and the heating element 211 is not limited thereto. The arrangement of 211 and the steam generator 12 can be arbitrarily changed as appropriate. That is, similarly to the above-described embodiment, the water vapor generator 12 may be disposed on the skin side of the wearer H with respect to the heating element.

  Further, in the above-described embodiment and each modification, two left and right main body portions 1 and 1 (201 and 301) are provided so as to correspond to the left and right eyes E and E, respectively, and the corresponding eyes E are independently provided. Although it was set as the structure which can provide warm heat, it is an example and is not restricted to this, The shape of the main-body part 1 can be changed arbitrarily arbitrarily. For example, the main body 1 may have a shape that is long in the left-right direction covering the left and right eyes E, E.

  Moreover, in the said embodiment and each modification, although the eye heating tool 100 was illustrated and demonstrated as a heating tool, the said heating tool is not limited for eyes E use. That is, any heating tool can be used as long as it can be worn at a predetermined location such as a joint portion or a fracture location.

  In addition, it should be thought that embodiment disclosed this time is an illustration and restrictive at no points. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
