Detailed Description

The heater of patent document 1 still has room for improvement in the uniformity of heat generation.

The present invention relates to a warmer having a structure in which a heating element can generate heat more uniformly.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In all the drawings, the same components are denoted by the same reference numerals, and redundant description thereof will be omitted as appropriate.

First, the warmer 100 according to the present embodiment will be described with reference to fig. 1 to 5.

Fig. 1 shows a state in which the main body 10 and the pair of right and left ear portions 30 of the heating appliance 100 are spread flat. Fig. 1 shows a face of the heating device 100, which is a face side in a state where the heating device 100 is worn on the face of a user.

Fig. 2 shows a state in which the surface that becomes the face side in the worn state is the inside, and the heating device 100 is folded in two at the widthwise central portion of the main body 10 (the heating device 100 is folded in two). That is, fig. 2 shows a state in which the following 1 st and 2

nd portions

11 and 12 of the main body portion 10 overlap each other, and the left and

right ear portions

30 and 30 overlap each other. Fig. 2 shows the outward surface of the part 1 of the main body 10 of the heating device 100 in a state where the heating device 100 is worn on the face of the user.

Fig. 3 is a view showing a cross section (cross section along the line a-a in fig. 1) obtained by cutting the heating device 100 in the lateral direction which coincides with the arrangement direction of the 1 st part 11 and the 2 nd part 12 in a state where the heating device 100 is unfolded, and showing a surface facing the face side on the upper side and a surface facing the outside on the lower side in a state where the heating device 100 is worn on the face of the user.

In the present embodiment, the positional relationship (e.g., the vertical relationship) between the components of the heating appliance 100 will be described with reference to the positional relationship when the heating appliance 100 is worn on the face of the user with the head positioned above and the neck positioned below as shown in fig. 4, unless otherwise specified.

As shown in any one of fig. 1 to 4, the heating appliance 100 of the present embodiment includes: a main body part 10 worn along the face; a heating element 20 provided in the main body 10; and a pair of ear portions 30 provided at both ends of the body portion 10 in the lateral direction.

Each of the pair of ear portions 30 has an opening 30a for ear hanging. The ear opening 30a preferably extends along the side edge of the main body 10 (is formed in a vertically long shape having a long dimension in the longitudinal direction of the side edge of the main body 10). In the case of the present embodiment, the opening 30a for a hanging lug is a folding-line-shaped slit 31 having substantially no width.

The pair of ear portions 30 are respectively hooked to the ear portions, and the user can wear the warming apparatus 100 by hooking the ear portions 30 to the ears.

The ear portions 30 may be formed of a sheet material integral with the main body portion 10, or may be provided by joining a material separate from the main body portion 10 to the main body portion 10.

As shown in fig. 1, when the distance between the pair of ear portions 30 is W and the vertical dimension of the ear opening 30a is H in a state where the main body portion 10 and the pair of ear portions 30 are spread flat, H/W is 0.2 or more.

Here, the state in which the main body portion 10 and the pair of ear portions 30 are spread out flatly means a state in which the entire heating device 100 is spread out as flatly as possible and the entire heating device 100 is naturally placed (in a case where the heating device 100 includes the following three-dimensional structure portion 60 without applying a tensile force for stretching the heating device 100 to the surroundings, the strain of the entire three-dimensional structure portion 60 is equalized).

The distance W is, for example, a distance between the pair of ear portions 30 at the same height position as the center 20c in the vertical direction of the heat generating element 20 in a state where the entire warmer 100 is spread out as flat as possible. As shown in fig. 1, the distance between the pair of ear portions 30 is the same as the height of the center 20c of the heating element 20 in the vertical direction, and the distance between the edges of the pair of ear openings 30a on the side away from the main body 10 (see also fig. 7(a), 7(b), and 8, which will be described as a modification below).

The vertical dimension H of the opening for hanging lug 30a is the dimension of the opening for hanging lug 30a in the direction orthogonal to the arrangement direction (the direction of the distance W in fig. 1) of the pair of hanging lug 30, that is, the height difference between the upper end and the lower end of the opening for hanging lug 30a (the height difference between the lower end of the slit lower part 31a for hanging lug and the upper end of the slit upper part 31b for hanging lug).

The warmer 100 of the present invention has the following structure: the longitudinal dimension H of the ear opening 30a is greater than or equal to a certain degree than the distance W between the pair of ear portions 30. Accordingly, when the heating device 100 is worn, the side edge portion (the bent portion 81 shown in fig. 4) of the main body 10 can be bent to protrude forward, so that the external air can be smoothly introduced from the side of the main body 10 between the main body 10 and the face portion, and the heating element 20 can be more uniformly heated. The reason why the bent portion 81 is formed is as follows: the human face is convex toward the front, and the ears are located more rearward than the eyes or cheeks.

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

(1) The "upper end and lower end of the portion of the ear portion 30 closer to the body portion 10 than the ear opening 30a (the ear slit 31 in fig. 1) and along the ear opening 30 a", or the "upper end and lower end of the portion of the side edge of the body portion 10 and along the ear opening 30 a" are located relatively rearward and are disposed in the cheek in the vicinity of the portion adjacent to the front side of the ear portion.

(2) The "middle portion in the vertical direction of the portion of the hanger part 30 closer to the main body part 10 than the hanger opening 30a and along the hanger opening 30 a" or the "middle portion in the vertical direction of the portion of the side edge of the main body part 10 along the hanger opening 30 a" is located relatively forward and is disposed at a position laterally apart from the portion adjacent to the front side of the ear part in the cheek.

Further, H/W is preferably 0.25 or more, and thus, the bending portion 81 can be bent more reliably. Further, H/W is preferably 0.7 or less, more preferably 0.6 or less.

Further, when the circumferential length of the opening 30a for the lug, which is on the side away from the main body 10 and connects the upper end and the lower end, is L, H/L is preferably 0.6 or more, and thus the bending portion 81 can be bent more reliably. In the case of the present embodiment, the circumferential length L is the sum of the length L11 and the length L12 shown in fig. 1.

In the case of the ear hanging slit 31 in which the ear hanging opening 30a does not substantially have a width as in the present embodiment, the circumferential length of the side of the ear hanging opening 30a remote from the main body 10 may be the total extension length of the ear hanging slit 31, that is, the sum of the length dimension of the ear hanging slit lower portion 31a and the length dimension of the ear hanging slit upper portion 31 b.

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

In the case of the present embodiment, the main body portion 10 is in a sheet shape (planar shape) having the following three-dimensional structure portion 60, and is formed in a size capable of covering a portion of the face from the eyes to the cheeks.

Here, the main body portion 10 covers the eye portion means covering the front (front side) of the entire eye socket (around the eye portion). The body section 10 covering the cheek means covering at least the front (front surface side) of the lower end position of the cheekbones. That is, the region of the face from the eye to the cheek covered by the body 10 is a region covering the front of the range from the upper portion around the eye to the lower portion of the cheekbones.

Since the main body 10 is formed in a size capable of covering the above-mentioned portion, the surface portion covered by the main body 10 can be warmed in a wide range by the heating element 20 disposed in the main body 10.

In the case of the present embodiment, a slit 54 extending upward from the lower edge of the main body 10 is formed in the widthwise central portion of the main body 10. The slit 54 is not limited to a linear (straight line or the like) slit, and may be a cut portion having a shape such as an inverted V-shape or an inverted U-shape. In the case of the present embodiment, the slit 54 is a linear slit in the folded state as shown in fig. 2, but is opened in an inverted V shape in the unfolded state as shown in fig. 1.

A slit 54 extending upward from the lower edge of the main body 10 is formed in the widthwise central portion of the main body 10, so that the external air can be smoothly introduced from below the main body 10 to between the lower portion of the main body 10 and the surface portion, and the external air can be supplied to the heating element 20 to generate heat from the heating element 20.

In the case of the present embodiment, the upper edge of the main body 10 extends substantially horizontally or is slightly inclined upward toward the center (is formed in an upwardly convex mountain shape), and a curved three-dimensional structure portion 60 is formed at the upper portion of the widthwise center of the main body 10 so that the upper portion is convex toward the front (details will be described later).

Therefore, the upper edge of the widthwise central portion of the main body 10 can be easily brought into close contact with or close to the forehead, and the escape of warm air from the gap upward can be suppressed, and the interior of the three-dimensional structure portion 60 can be filled with warm air. This allows the face covered by the body 10 to be sufficiently warmed over a wide range.

As described above, according to the heating device 100, the body 10 can cover the region of the face from the eyes to the cheeks, and the heating element 20 can widely warm the face. Further, the external air can be smoothly introduced from the bent portion 81 along the opening 30a for the hanging lug, and also can be smoothly introduced from the lower side of the main body portion 10, so that the entire heating element 20 can be heated. This allows the wide area of the face to be warmed more sufficiently.

Since the heating device 100 includes the three-dimensional structure portion 60, when the heating device 100 is worn, the upper portion of the widthwise central portion of the main body 10 is formed in a convex shape, and the side edge portion of the main body 10 is easily bent, so that the side edge portion (the bent portion 81 shown in fig. 4) of the main body 10 can be more easily bent in a convex manner toward the front. Therefore, the outside air can be introduced more smoothly from the side of the body 10 to between the body 10 and the surface, and the entire heating element 20 can be heated more uniformly.

In the case of the present embodiment, the heating appliance 100 is a steam heating appliance as described below. Therefore, similarly to the case of the air described above, the escape of steam from the gap between the upper edge of the widthwise central portion of the main body 10 and the face portion can be suppressed, and the space between the main body 10 and the face portion can be filled with steam.

The main body 10 is sized and shaped to cover both eyes and cheeks.

The main body 10 includes a 1 st portion 11 covering a region from the left eye to the left cheek, and a 2 nd portion 12 covering a region from the right eye to the right cheek.

The 1 st part 11 and the 2 nd part 12 are formed in substantially the same shape and size as each other. In fig. 1, the 1 st part 11 and the 2 nd part 12 are arranged side by side, and are separated from each other through a slit 54 in a lower portion of the main body 10.

The planar shape of the main body 10 is not particularly limited, and may be a substantially rectangular shape having a slightly lateral length, as shown in fig. 1, for example. Since the slit 54 is formed in the main body 10, an inverted V-shaped or inverted U-shaped notch is formed in the lower portion of the widthwise central portion of the main body 10.

The planar shapes of the 1 st and 2

nd portions

11 and 12 may be, for example, substantially quadrangular shapes (for example, slightly elongated quadrangular shapes) which are slightly larger than the heat generating element 20.

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

In fig. 1, the upper edge of the main body 10 is slightly inclined upward toward the center (formed in a mountain shape that is convex upward), but in a state where the heating device 100 is folded in two as shown in fig. 2, for example, the upper edge of the main body 10 is inclined downward toward the side edge of the main body 10.

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

The vertical dimension of the main body portion 10 perpendicular to the lateral width direction is set so that the main body portion 10 can cover, for example, a portion slightly above the upper edge of the eyebrow ridge to a portion slightly below the mouth corner.

The side edge portion of the body 10 covers, for example, the region from the temple to the vicinity of the rear end of the cheek (the region of the cheek adjacent to the front side of the ear).

In the 1 st and 2

nd parts

11 and 12, the portion along the slit 54 extends, for example, from the nose side along the grain.

The lower ends of the 1 st and 2

nd parts

11 and 12 are located, for example, further down than the lower lip.

More specifically, for example, a portion of the heat generating element 20 along the slit 54 (the inner edge 25 shown in fig. 1 and 4) extends along the grain, and a lower end portion of the main body 10 along the slit 54 covers the nozzle corner.

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

In the case of the present embodiment, the heating unit 100 includes the 1 st sheet 51 and the 2 nd sheet 52 disposed to overlap the 1 st sheet 51.

Each of the 1 st sheet 51 and the 2 nd sheet 52 may be a single-layer sheet or a multilayer sheet.

The 1 st sheet 51 and the 2 nd sheet 52 are each made of a flexible material. Examples of the material of the 1 st sheet 51 and the 2 nd sheet 52 include a nonwoven fabric, a woven fabric, another woven fabric, a resin film such as polyethylene or urethane, a porous body, and a combination of any 2 or more of these.

The 1 st sheet 51 is formed in the shape of the main body 10, for example.

On the other hand, the 2 nd sheet 52 is formed in the same shape as the overall shape of the warming appliance 100. More specifically, as shown in fig. 1, the left and right end portions of the 2 nd sheet 52 extend from the 1 st sheet 51, and the extending portions constitute the left and right ear portions 30. When the warmer 100 is worn, the 1 st sheet 51 is positioned on the face side, and the 2 nd sheet 52 is positioned on the opposite side (i.e., outward) from the face.

As shown in fig. 3, mutually opposing faces of the 1 st sheet 51 and the 2 nd sheet 52 are mutually engaged with each other at an engaging portion 53.

The 1 st sheet 51 and the 2 nd sheet 52 may be joined by adhesion or adhesion, or may be joined by heat sealing. In the case of the present embodiment, the joining portion 53 is formed by, for example, heat fusion.

The joint portion 53 is disposed, for example, on the entire periphery of the peripheral edge portion of the main body portion 10 and on the range from the upper edge to the lower edge of the central portion in the lateral width direction of the main body portion 10. More specifically, the joint portion 53 is disposed, for example, on the entire periphery of the peripheral edge portion of the 1 st portion 11 and the entire periphery of the peripheral edge portion of the 2 nd portion 12.

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

Between the 1 st sheet 51 and the 2 nd sheet 52, the heat generating body 20 is provided.

More specifically, in each of the 1 st and 2

nd sections

11 and 12, the heat generating element 20 is provided between the 1 st and 2

nd sheets

51 and 52.

In the case of the present embodiment, the arrangement region of the heat generating element 20 is set to a size covering a range from the eyes to a region lower than the mouth corner in the cheek.

This allows the face to be warmed more sufficiently over a wide range from the eyes to the cheeks (lower parts than the corners of the mouth in the cheeks).

More specifically, the heat-generating elements 20 provided in the 1 st part 11 are set to have a size covering a range from the left eye to a portion lower than the left mouth corner in the left cheek, and the heat-generating elements 20 provided in the 2 nd part 12 are set to have a size covering a range from the right eye to a portion lower than the right mouth corner in the right cheek.

The heating element 20 provided in the 1 st part 11 is set to a size covering the left temple, and the heating element 20 provided in the 2 nd part 12 is set to a size covering the right temple.

Here, in the 1 st part 11, a single heating element may be provided, or a heating element group which is an aggregate of a plurality of heating elements arranged adjacent to each other or in close proximity may be provided.

Similarly, in the 2 nd part 12, a single heating element may be provided, or a heating element group which is an aggregate of a plurality of heating elements arranged adjacent to each other or in close proximity may be provided.

The heat-generating body 20 means a single heat-generating body, or a heat-generating body group as referred to herein. Therefore, the arrangement region of the heating elements 20 may be an arrangement region of a single heating element or an arrangement region of a heating element group.

The planar shape of the arrangement region of the heating elements 20 in the 1 st and 2

nd parts

11 and 12 is not particularly limited, and in the case of the present embodiment, for example, the arrangement region of each heating element 20 is formed in a rectangular shape (for example, a square shape).

As shown in fig. 1, the upper edge of the arrangement region of the heating element 20 is inclined upward toward the side edge of the main body 10, for example. Therefore, the vertical dimension of the region between the upper edge of the arrangement region of the heating element 20 and the upper edge of the main body 10 (i.e., the region above the heating element 20 where the heating element 20 is not present) gradually increases, for example, toward the widthwise center of the main body 10 (gradually decreases toward the side edge of the main body 10). Thus, the upper portion of the widthwise central portion of the main body portion 10 is formed into a curved shape that projects forward, and the upper edge of the heat generating device 100 can be easily attached to or brought into close contact with the forehead.

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

On the other hand, in the heat-generating body 20, an edge portion (outer edge 26 shown in fig. 1) on the opposite side to the inner edge 25 extends, for example, along the side 51a (fig. 1) of the 1 st sheet 51 (e.g., extends parallel to the side 51 a). The outer edge 26 is disposed, for example, closely to the side edge 51 a.

As shown in fig. 3, the heating element 20 is configured to include, for example, a 1 st coated sheet 21, a 2 nd coated sheet 22, and a sheet-like heating element 23 held between the 1 st coated sheet 21 and the 2 nd coated sheet 22.

The 1 st coated sheet 21 and the 2 nd coated sheet 22 are formed in the same shape and size, for example. Further, they are overlapped with each other so that their outline lines are uniform, and their peripheral edge portions are joined to each other. This constitutes a housing for housing the heating material 23 therein. The joining of the 1 st and 2 nd coated

sheets

21 and 22 may be accomplished by adhesion or adhesion, or by heat sealing.

The planar shapes of the 1 st and 2 nd coated

sheets

21 and 22 are not particularly limited, and in the case of the present embodiment, the 1 st and 2 nd coated

sheets

21 and 22 are each formed in a rectangular shape (for example, a square shape), for example.

The 1 st coated sheet 21 is disposed on the 1 st sheet 51 side, i.e., on the side that becomes the face side when the thermal appliance 100 is worn, and the 2 nd coated sheet 22 is disposed on the 2 nd sheet 52 side, i.e., on the side opposite to the face side (front side) when worn.

The heat generating material 23 is configured to contain an oxidizable metal. The heat generating material 23 generates heat by an oxidation reaction caused by contact between the oxidizable metal and oxygen. In the case of the present embodiment, the heat generating material 23 is configured to generate heated water vapor by heat generated in an oxidation reaction caused by contact between the oxidizable metal and oxygen.

The heating material 23 includes, for example, an oxidizable metal, a reaction accelerator, an electrolyte, and water.

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

In one housing body constituted by the 1 st coated sheet 21 and the 2 nd coated sheet 22, 1 heating member 23 or a plurality of heating members 23 may be housed.

The "single heating element" includes one housing and 1 or more heating elements 23 housed in the one housing.

On the other hand, the "heat generating element group" is configured by disposing a plurality of "single heat generating elements" configured as described above adjacent to each other or in close proximity to each other.

For example, 1 or more of the heat generating materials 23 are arranged in a rectangular (for example, square) region smaller than the 1 st covering sheet 21 and the 2 nd covering sheet 22.

The heating material 23 is preferably bonded to at least one of the 1 st covering sheet 21 and the 2 nd covering sheet 22.

The joining portion 53 joins the peripheral edge portion of the heat generating body 20 and at least one of the 1 st sheet 51 and the 2 nd sheet 52 to each other. That is, the joining portion 53 joins the 1 st coated sheet 21 and the 1 st sheet 51 to each other, or joins the 2 nd coated sheet 22 and the 2 nd sheet 52 to each other. In the case of the present embodiment, for example, as shown in fig. 3, the joining portion 53 joins the 1 st coated sheet 21 and the 1 st sheet 51 to each other, and joins the 2 nd coated sheet 22 and the 2 nd sheet 52 to each other.

Thus, the left and right heating elements 20 are held in the 1 st and 2

nd sections

11 and 12, respectively.

In the central portion (portion other than the peripheral portion) of the heating element 20, for example, the heating element 20 and the 1 st sheet 51 are not joined to each other, and the heating element 20 and the 2 nd sheet 52 are not joined to each other (see fig. 3).

At least one of the 1 st and 2 nd coated

sheets

21 and 22 of the heat-generating body 20 has air permeability.

In the case of the present embodiment, the 1 st coated sheet 21 has air permeability. The 1 st coated sheet 21 has higher air permeability than the 2 nd coated sheet 22. The 2 nd coated sheet 22 may be air-permeable or substantially air-impermeable.

Further, the 1 st coated sheet 21 has air permeability so as to allow air and water vapor to pass therethrough. On the other hand, the 2 nd coated sheet 22 is less breathable or non-breathable than the 1 st coated sheet 21.

The air permeability of the 1 st coated sheet 21 is preferably 1000 seconds/100 ml or more, and more preferably 2000 seconds/100 ml or more, in terms of sufficiently warming a wide area of the face. Further, it is preferably 50000 seconds/100 ml or less, more preferably 20000 seconds/100 ml or less, and further preferably 10000 seconds/100 ml or less.

Air permeability is a value measured in accordance with JIS P8117, and passed through 6.45cm of air of 100ml under a fixed pressure²Time definition of the area of (a). The air permeability can be measured by a penetrometer of the Wang type or a measuring machine based on the penetrometer.

As such a breathable sheet, a porous sheet made of a resin having moisture permeability but no water permeability or a sheet made of a resin having air permeable pores can be used, and for example, polyethylene, polypropylene, an ethylene-vinyl acetate copolymer, or the like can be used.

The resin porous sheet can be obtained by molding a melt-kneaded product of a thermoplastic resin and an organic or inorganic filler incompatible with the resin into a film and uniaxially or biaxially stretching the film. Further, it is possible to provide the air-impermeable sheet or the hardly air-permeable sheet with micropores by using needles or the like, or to provide the air-permeable sheet with micropores by using needles or the like. The thickness of the air-permeable sheet is preferably 5 μm or more and 200 μm or less.

On the other hand, the 2 nd coated sheet 22 may be a breathable sheet or a non-breathable sheet. When the 2 nd coated sheet 22 is an air-permeable sheet, the air permeability is preferably 80000 seconds/100 ml or more. When the 2 nd coated sheet 22 is a non-air-permeable sheet, a laminated sheet obtained by laminating a non-air-permeable resin film and paper or the like can be used as the non-air-permeable sheet.

The 1 st coated sheet 21 and the 2 nd coated sheet 22 may be each composed of 1 sheet, or may be composed of a laminate of a plurality of sheets. As such a laminate, a laminate obtained by laminating a nonwoven fabric and an air-permeable sheet, or a laminate obtained by laminating a woven fabric and an air-permeable sheet can be used.

In the case of the present embodiment, as described above, the heat generating material 23 generates heat to generate water vapor, and the 1 st coated sheet 21 has moisture permeability and the 1 st sheet 51 has moisture permeability. Therefore, the steam can be released through the face of the main body 10, which is the face side, and can be brought into contact with the face.

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

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

The vertical dimension of the ear portion 30 is set to be, for example, the same as the vertical dimension of the main body portion 10.

Since the ear portion 30 is vertically long, the upper end portion and the lower end portion of the side edge portion of the body portion 10 can be pulled rearward by the ear portion 30, and therefore the bent portion 81 can be bent sufficiently.

In the case of the present embodiment, the ear portion 30 has a vertically long ear slit 31 as an ear opening 30 a. When the heating device 100 is worn, as shown in fig. 4, the body 10 is closely attached to the face from the eye 75 to the cheek 76, the left and right ear portions 74 are inserted into the ear slits 31 of the left and right ear portions 30, and then the ear portions 30 are hooked behind the ear portions 74.

More specifically, the height position of the lower end of the hanger slit 31 is set to, for example, a height position substantially equal to the lower end of the heating element 20. On the other hand, the height position of the upper end of the hanger slit 31 is set, for example, below the upper end of the heat generating element 20 and above the center 20c (fig. 1 and 2) of the heat generating element 20 in the vertical direction.

That is, the hanger slit 31 is disposed slightly below the heating element 20. With such an arrangement of the ear hanging slit 31, the slit 54 can be opened largely in an inverted V-shape or an inverted U-shape when the thermal appliance 100 is worn, and the size of the gap between the three-dimensional structure portion 60 and the face can be sufficiently secured. Further, since the upper portion of the body 10 can be pulled more strongly rearward, the bending portion 81 can be bent sufficiently.

A portion between the upper end of the ear slit 31 and the upper edge of the ear portion 30 is an ear upper connection portion 32 that connects a portion of the ear portion 30 on the side closer to the main body portion 10 than the ear slit 31 and a portion on the side farther from the main body portion 10 than the ear slit 31 above the ear slit 31.

Similarly, a portion between the lower end of the ear slit 31 and the lower edge of the ear portion 30 is an ear lower connection portion 33 that connects a portion of the ear portion 30 on the side closer to the main body 10 than the ear slit 31 and a portion on the side farther from the main body 10 than the ear slit 31 below the ear slit 31.

In the case of the present embodiment, the vertical width L1 (fig. 1 and 2) of the upper lug link 32 is set to be larger than the vertical width L2 (fig. 1 and 2) of the lower lug link 33. In other words, the distance between the upper edge of the tab portion 30 and the upper end of the tab slit 31 is greater than the distance between the lower end of the tab slit 31 and the lower edge of the tab portion 30.

This can suppress the pulling of the upper ear connection part 32 when the thermal appliance 100 is worn, and the upper part of the side edge part of the body part 10 can be pulled more sufficiently rearward by the ear part 30 when the ear part 30 is hooked to the ear part. This makes it possible to sufficiently bend the bending portion 81 as shown in fig. 4, and to make the portion of the main body 10 closer to the widthwise center than the bending portion 81 fit to the face well.

On the other hand, since the lower hanger connecting portion 33 can be appropriately stretched, the hanger 30 can be satisfactorily attached to the ear regardless of the size of the ear of the user.

Here, the vertical width L1 may be set to be, for example, a distance between the upper edge of the ear portion 30 and the upper end of the ear slit 31 on a straight line AX1 (fig. 1 and 2) connecting the upper end and the lower end of the ear slit 31.

The vertical width L2 may be set to be a distance between the lower edge of the ear portion 30 and the lower end of the ear slit 31 on the straight line AX1 (fig. 1 and 2).

The ear slit 31 is curved convexly in the lateral width direction, for example, in a direction away from the main body 10. That is, in the expanded state shown in fig. 1, the left-side ear hanging slit 31 is convexly curved to the left, and the right-side ear hanging slit 31 is convexly curved to the right.

More specifically, in the case of the present embodiment, the ear slit 31 is formed in a zigzag shape that is bent to protrude in a direction away from the main body 10 in the lateral width direction, for example.

The ear slit 31 includes, for example, a linear ear slit lower portion 31a constituting a lower portion of the ear slit 31 and a linear ear slit upper portion 31b constituting an upper portion of the ear slit 31.

The bent portion 31c of the ear slit 31, which is the boundary between the ear slit lower portion 31a and the ear slit upper portion 31b, is disposed below the central position (ear slit center 31d) of the ear slit 31 in the vertical direction.

Since the bent portion 31c of the ear slit 31 is disposed below the ear slit center 31d, when the ear portion is passed through the ear slit 31 and the ear portion 30 is hooked to the ear portion, a portion 35 (see fig. 1) of the ear portion 30 along the ear slit upper portion 31b is opened over a longer distance at the ear portion and is bent in a direction away from the body portion 10. That is, the upper portion of the body 10 is pulled more strongly rearward. This allows the bending portion 81 to be sufficiently bent as shown in fig. 4.

In particular, when the vertical width L1 is larger than the vertical width L2 as described above, the bent portion 31c of the ear slit 31 is disposed below the ear slit center 31d, whereby the extension of the ear upper connection portion 32 can be suppressed, and therefore the upper portion of the body 10 can be pulled more strongly rearward, and the bent portion 81 can be bent sufficiently.

In the case of the present embodiment, the lower end of the lower hooking slit part 31a and the side 51a of the 1 st sheet 51 are disposed close to each other, and the upper end of the upper hooking slit part 31b and the side 51a of the 1 st sheet 51 are disposed close to each other. Accordingly, since the extension of the upper and

lower hangers

32 and 33 can be appropriately suppressed, the upper and lower ends of the side edge of the main body 10 can be sufficiently pulled by the ear 30.

In the case of the present embodiment, the distance between the lower end of the lower hanger slit part 31a and the outer edge 26 of the heating element 20 and the distance between the upper end of the upper hanger slit part 31b and the outer edge 26 of the heating element 20 are set to be equal to each other.

It is preferable that the center 20c of the heating element 20 in the vertical direction and the center position of the opening for the lug in the vertical direction (the lug slit center 31d in the example of fig. 1) are arranged at the same height position, and by this configuration, the bent portion 81 can be bent more reliably. The height difference between the center 20c and the central position in the vertical direction of the opening for hanging ring (for example, the slit center 31d for hanging ring) is preferably 3cm or less, more preferably 2cm or less, and still more preferably 1cm or less.

When a plurality of heating elements 20 are disposed in the 1 st part 11 or the 2 nd part 12 of the main body 10, it is preferable that the center position of the assembly of the plurality of heating elements 20 and the center position in the vertical direction of the opening for hanging ears are disposed at the same height position, and the height difference thereof is, for example, preferably 3cm or less, more preferably 2cm or less, and still more preferably 1cm or less.

In the present invention, the shape of the ear slit 31 is not limited to the zigzag shape as in the present embodiment, and may be formed in a curved shape (arc shape or the like) protruding in a direction (lateral direction) away from the body 10.

Here, the three-dimensional structure portion 60 will be described.

As described above, the main body 10 includes: a 1 st portion 11 covering a portion from one eye (left eye) to one cheek (left cheek); and a 2 nd portion 12 covering a region from the other eye (right eye) to the other cheek (right cheek).

In the case of the present embodiment, the three-dimensional structure portion 60 is a connecting portion 61 that connects the 1 st part 11 and the 2 nd part 12 to each other above the slit 54.

The connection portion 61 includes: a lower connecting portion 61a extending upward and downward; and an upper connecting portion 61b adjacent to an upper side of the lower connecting portion 61a and extending vertically.

As shown in fig. 2, in the state where the heating device 100 is folded in two, the lower connecting portion 61a and the upper connecting portion 61b are not aligned with each other, but are bent at the boundary portion thereof, more specifically, the lower connecting portion 61a and the upper connecting portion 61b are bent at an angle α.

When the main body 10 is unfolded, the upper portion of the widthwise central portion of the main body 10 is formed into a curved shape that bulges forward (see fig. 4).

The angle α (fig. 2) is preferably 120 degrees or more and 170 degrees or less, and more preferably 130 degrees or more and 160 degrees or less, and by providing such an angle, when the heating appliance 100 is worn, the upper edge of the widthwise central portion of the main body portion 10 can be brought into close contact or close contact with the forehead 71 (see fig. 4), and a sufficient gap between the face and the three-dimensional structure portion 60 can be secured, and the gap can be filled with a sufficient volume of warm air.

As described above, the slit 54 is formed in the widthwise central portion of the main body 10. The slit 54 extends upward from the lower edge of the main body 10.

Here, the vertical dimension H2 (fig. 2 and 5) of the slit 54 is preferably 40% or more of the vertical dimension H1 of the central portion of the body 10. The vertical dimension H2 is more preferably 50% or more of the vertical dimension H1.

If the vertical dimension H2 is 40% or more of the vertical dimension H1, the linear slit 54 can be opened widely in an inverted V-shape or an inverted U-shape in the folded state shown in fig. 2 when the main body 10 is unfolded and the three-dimensional structure portion 60 is formed in a three-dimensional shape as shown in fig. 1. That is, when the warmer 100 is worn on the face as shown in fig. 4, the slit 54 can be opened largely in an inverted V-shape or an inverted U-shape. This allows the outside air to be introduced more smoothly from below the body 10 to between the lower portion of the body 10 and the face.

For example, when the warmer 100 is worn on the face as shown in fig. 4, it is preferable that the nose 72 and the mouth 73 are exposed through the slit 54, so that breathing can be easily performed when the warmer 100 is worn.

The vertical dimension H2 is preferably 75% or less, and more preferably 70% or less of the vertical dimension H1.

When the slit 54 is largely opened in the inverted V-shape or the inverted U-shape as described above, the vertically long shape of the ear portion 30 can be inclined when the main body portion 10 and the ear portion 30 are unfolded as shown in fig. 1, compared to when the warmer 100 is folded in two as shown in fig. 2.

That is, in the state of fig. 1, the straight line AX1 connecting the upper end and the lower end of the ear slit 31 is inclined toward the upper portion of the straight line AX1 toward the widthwise central portion of the body 10, as compared with the state of fig. 2.

Therefore, when the heating appliance 100 is worn, the upper portion of the ear portion 30 is pulled more strongly rearward, and the bending portion 81 can be bent more sufficiently.

Further, the slit 54 is opened largely in the shape of an inverted V or U, so that each heating element 20 can be attached well to the area from the eyes to the cheeks of the face.

Before use, the heating appliance 100 is sealed in a packaging bag (not shown) made of a packaging material having an oxygen barrier property, for example. When the heating device 100 is taken out from the packaging bag at the time of use, the heat generating material 23 of the heat generating element 20 comes into contact with oxygen in the air, the heat generating material 23 generates heat and generates water vapor (steam warmth), and the water vapor is released to the outside through the 1 st coated sheet 21 and the 1 st sheet 51.

Thus, the water vapor is supplied to the face of the user as the user wears the warming appliance 100. This may warm the face of the user with the hot towel. As described above, the heating appliance 100 of the present embodiment is a steam heating appliance.

In order to wear the heating device 100, the 1 st sheet 51 of the main body 10 is made to face side, the 1 st and 2

nd portions

11 and 12 are respectively brought into close contact with the regions from the left and right eye portions 75 to the cheeks 76, and the pair of ear portions 30 are respectively hooked on the left and right ear portions 74.

Here, an example of a method for forming the three-dimensional structure portion 60 will be described with reference to fig. 5.

The warmer constituting sheet 120 shown in fig. 5 is a material for producing the warmer 100. The difference between the heater constituting sheet 120 and the heater 100 is that the pair of right and left pre-joint portions 56 shown in fig. 5 are not joined to each other, but are otherwise configured similarly to the heater 100.

For example, as shown in fig. 5, in the 1 st sheet 51 and the 2 nd sheet 52, a V-shaped notch portion 55 is formed at an upper edge portion of the widthwise central portion of the main body portion 10, whereby a heater constituting sheet 120 is obtained. Further, by joining the pair of preliminary joining portions 56, which are the left and right side edges of the cutout-shaped portion 55, to each other, the upper connecting portion 61b of the three-dimensional structure portion 60 is formed as shown in fig. 1 and 2, and the heating appliance 100 is manufactured.

The lower connecting portion 61a of the three-dimensional structure portion 60 is, for example, a portion on the 1 st portion 11 side and a portion on the 2 nd portion 12 side of the 1 st sheet 51 and the 2 nd sheet 52, which are originally connected to each other.

The method of forming the three-dimensional structure portion 60 is not limited to this example, and for example, a straight slit (not shown) extending vertically may be formed in the upper edge portion of the widthwise central portion of the main body portion 10 in the 1 st sheet 51 and the 2 nd sheet 52, and the left and right portions of the slit may be overlapped and joined to each other, thereby forming the three-dimensional structure portion 60 similar to that shown in fig. 1 and 2.

Alternatively, the configurations of the lower connecting portion 61a and the upper connecting portion 61b may be reversed from those of the present embodiment. In this case, the upper connecting portion 61b is a portion that originally connects the portion on the 1 st portion 11 side and the portion on the 2 nd portion 12 side of the 1 st sheet 51 and the 2 nd sheet 52 to each other. On the other hand, the lower connecting portion 61a is formed by joining the left and right side edges of the slit connected to the upper side of the slit 54 to each other.

Alternatively, the three-dimensional structure portion 60 may be formed by embossing (pressing) the upper portion of the widthwise central portion of the main body 10.

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

The heating device 100 preferably has a maximum surface temperature of 38 to 70 ℃. The maximum surface temperature and the amount of water vapor generated by the heating device 100 were measured by the following method using the device 90 shown in fig. 6. The apparatus 90 shown in fig. 6 includes: a measuring chamber (volume 4L)91 made of aluminum; an inflow path 92 through which dehumidified air (humidity less than 2%, flow rate 2.1L/min) flows into a lower portion of the measurement chamber 91; an outflow path 93 through which air flows out from the upper portion of the measurement chamber 91; an inlet thermo-hygrometer 94 and an inlet flow meter 95 provided in the inflow path 92; an outlet thermo-hygrometer 96 and an outlet flow meter 97 provided in the outflow path 93; and a thermometer (thermistor) 98 provided in the measurement chamber 91. As the thermometer 98, a thermometer having a temperature resolution of about 0.01 ℃ was used.

The measurement of the maximum surface temperature of the warmer 100 was carried out by taking the warmer 100 out of the packaging bag at a measurement ambient temperature of 30 ℃ (30 ± 1 ℃), placing the warmer 100 in the measurement chamber 91 with the face side surface of the warmer 100 (the 1 st sheet 51 side surface of the 1 st sheet 51 and the 2 nd sheet 52) facing upward, and placing the thermometer 98 with the metal ball (mass 4.5g) in the measurement chamber 91.

In this state, the dehumidified air flows in from the lower portion, the difference in absolute humidity before and after the air flows into the measurement chamber 91 is obtained from the temperature and humidity measured by the inlet thermo-hygrometer 94 and the outlet thermo-hygrometer 96, and the amount of water vapor released from the heater 100 is calculated from the flow rates measured by the inlet flowmeter 95 and the outlet flowmeter 97.

The surface temperature in the present specification means the maximum reaching temperature of the surface of the heating device 100 after the heating device 100 is taken out from the packaging bag, that is, after the generation of water vapor is started, and the amount of water vapor generated in the present specification means the total amount of water vapor measured from the time point when the heating device 100 is taken out from the oxygen barrier bag, that is, from the time when the generation of water vapor is started, to 10 minutes later.

According to the above-described embodiment, when the distance between the pair of ear portions 30 is W and the vertical dimension of the ear opening 30a is H in a state where the main body portion 10 and the pair of ear portions 30 are spread flat, H/W is 0.2 or more.

With this configuration, when the heating device 100 is worn, the side edge portion (the bent portion 81 shown in fig. 4) of the main body 10 can be bent to protrude forward, so that the external air can be smoothly introduced from the side of the main body 10 between the main body 10 and the face portion, and the heating element 20 can be more uniformly heated.

Next, a modification of the above embodiment will be described.

As in modification 1 shown in fig. 7(a) and modification 2 shown in fig. 7(b), the ear opening 30a may be an ear slit 31 having a laterally wide shape. In the case of modification 1 shown in fig. 7(a), the circumferential length L of the opening 30a for hangers on the side away from the main body 10 is the sum of the length L11 and the length L12 shown in fig. 7 (a).

In the case of modification 2 shown in fig. 7(b), the circumferential length L of the opening for hanging lug 30a on the side away from the body 10 is a length L13 shown in fig. 7(b), which is a length along the edge on the side away from the body 10 with reference to a length axis AX2 connecting the upper end and the lower end of the opening for hanging lug 30 a.

As in modification 3 shown in fig. 8, the ear portion 30 may be a cord (e.g., a cord having elasticity). In this case, the opening 30a for the lug is an opening formed between the string and the main body 10, and the circumferential length L of the opening 30a for the lug on the side away from the main body 10 is the length of the inner circumferential side portion of the string.

The present invention is not limited to the above-described embodiments and modifications, and various modifications and improvements may be made to the embodiments as long as the object of the present invention is achieved.

For example, although the example in which the number of three-dimensional structure portions 60 formed in the main body portion 10 is 1 has been described above, a plurality of (for example, 2) three-dimensional structure portions 60 may be arranged side by side.

In the above, the example in which the main body portion 10 and the pair of ear portions 30 are formed by the respective portions of the continuous sheet material (the 2 nd sheet material 52) has been described, but the ear portions 30 may be provided on the main body portion 10 by joining a sheet material separate from the sheet material forming the main body portion 10 to the sheet material forming the main body portion 10.

The heating element 20 may be a heat generating element that does not emit steam. Thus, the warmer 100 may also be a simple warmer, rather than a steam warmer.
