Accordingly, as shown in FIG. 4, the curved portion 81 can be sufficiently curved, and a portion closer to the center in the lateral width direction than the curved portion 81 in the main body portion 10 can be favorably fitted to the face.
On the other hand, since the moderate extension of the ear hook lower connection portion 33 can be realized, the ear hook portion 30 can be favorably fitted to the ear regardless of the size of the user's ear.

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

The ear hooking slit 31 is, for example, convexly curved in the lateral width direction away from the main body 10. That is, in the unfolded state shown in FIG. 1, the left ear hooking slit 31 is convexly curved toward the left, and the right ear hooking slit 31 is convexly curved toward the right.
More specifically, in the case of the present embodiment, the ear hooking slit 31 is formed in, for example, a bent line shape which is bent in a convex direction in a direction away from the main body portion 10 in the lateral width direction.
The ear hooking slit 31 includes, for example, a linear ear hooking slit lower portion 31a constituting a lower portion of the ear hooking slit 31, and a linear ear hooking slit upper portion 31b constituting an upper portion of the ear hooking slit 31. And is comprised.
The bent portion 31c of the earpiece slit 31, which is the boundary between the earpiece slit lower portion 31a and the earpiece slit upper portion 31b, is the center position of the earpiece slit 31 in the vertical direction (the earpiece slit center 31d ) Is located below.

Since the bent portion 31c of the earpiece slit 31 is disposed below the earpiece slit center 31d, when the earpiece portion 30 is hooked to the ear through the earpiece slit 31, the earhook portion 30 is formed. In the above, the portion 35 (see FIG. 1) along the ear hooking slit upper portion 31b is pushed and spread by the ear for a longer distance, and is bent in the direction away from the main body portion 10. That is, the upper portion of the main body 10 is pulled backward more strongly. Therefore, as shown in FIG. 4, the bending portion 81 can be sufficiently bent.

In particular, when the vertical width dimension L1 is larger than the vertical width dimension L2 as described above, the bent portion 31c of the ear hooking slit 31 is disposed lower than the ear hooking slit center 31d. Since the extension of the ear hook upper connection portion 32 can be suppressed, the curved portion 81 can be sufficiently curved by pulling the upper portion of the main body portion 10 backward more strongly.

In the case of this embodiment, the lower end of the ear hooking slit lower portion 31a and the side 51a of the first sheet 51 are disposed close to each other, and the upper end of the ear hooking slit upper portion 31b and the side of the first sheet 51 The sides 51a are arranged close to each other. Thereby, since the expansion of the ear hook upper connection portion 32 and the ear hook lower connection portion 33 can be appropriately suppressed, the upper end portion and the lower end portion of the side edge portion of the main body portion 10 can be sufficiently pulled by the ear hook portion 30 It is possible.
Further, in the case of the present embodiment, the distance between the lower end of the ear hooking slit lower portion 31a and the outer edge 26 of the heating element 20 and the distance between the upper end of the ear hooking slit upper portion 31b and the outer edge 26 of the heating element 20 are mutually different. It is set to the same distance.

In addition, it is preferable that the center 20c in the vertical direction of the heat generating body 20 and the earpiece slit center 31d be disposed at the same height position with each other, such a configuration more reliably curves the curved portion 81. It can be done. The height difference between the center 20c and the middle portion 31d of the earpiece slit is, for example, preferably 3 cm or less, more preferably 2 cm or less, and still more preferably 1 cm or less.

In the present invention, the shape of the ear hooking slit 31 is not limited to the broken line shape as in the present embodiment, but is formed in a curved shape (arc shape etc.) convex in a direction (side) away from the main body 10 It may be done.

Here, the above-described three-dimensional structure unit 60 will be described.
As described above, the main body 10 covers the first portion 11 covering a region from one eye (left eye) to one cheek (left cheek), and from the other eye (right eye) to the other cheek (right cheek) And a second portion 12 covering the portion of
In the case of the present embodiment, the three-dimensional structure portion 60 is a connection portion 61 connecting the first portion 11 and the second portion 12 to each other above the slit 54.
The connection portion 61 includes a lower connection portion 61a extending vertically and an upper connection portion 61b adjacent to the upper side of the lower connection portion 61a and extending vertically. There is.
As shown in FIG. 2, in the state where the heating tool 100 is folded in two, the lower connection portion 61 a and the upper connection portion 61 b do not exist on the same straight line, and mutually at the boundary portion. It is bent. More specifically, the lower connection portion 61a and the upper connection portion 61b are bent at an angle α.

The angle α (FIG. 2) is preferably 120 degrees or more and 170 degrees or less, and more preferably 130 degrees or more and 160 degrees or less. By having such an angle, when the heating tool 100 is attached, the upper edge in the widthwise central portion of the main body portion 10 can be brought into close contact with or close to the forehead 71 (see FIG. 4). And the three-dimensional structure 60, and the space can be filled with a sufficient volume of warm air.

Further, as described above, the slit 54 is formed at the central portion in the width direction of the main body portion 10. The slit 54 extends upward from the lower edge of the main body 10.
Here, it is preferable that the upper and lower dimensions H2 (FIGS. 2 and 5) of the slits 54 be 40% or more of the upper and lower dimensions H1 of the central portion of the main body portion 10. More preferably, the upper and lower dimension H2 is 50% or more of the upper and lower dimension H1.

The slits 54 can be made to open largely in an inverted V-shape or an inverted U-shape. That is, as shown in FIG. 4, when the heating tool 100 is worn on the face, the slit 54 can be largely opened in an inverted V shape or an inverted U shape and can be extended along the statute line. By this, external air can be more smoothly introduced between the lower part of the main body 10 and the face from the lower side of the main body 10.
For example, as shown in FIG. 4, when the heating tool 100 is worn on the face, it is preferable that the nose 72 and the mouth 73 be exposed through the slits 54, whereby the heating tool 100 is You will be able to breathe comfortably when wearing
In addition, 75% or less of the upper and lower dimension H1 is preferable, and 70% or less of the upper and lower dimension H2 is more preferable.

The ear hooking portion 30 can be inclined as compared to the case where the 100 is folded in half.
That is, in the state of FIG. 1, the straight line AX1 connecting the upper end and the lower end of the ear hooking slit 31 approaches the center of the widthwise direction of the main body 10 toward the upper portion of the straight line AX1 compared to the state of FIG. So as to tilt.
For this reason, when the heating implement 100 is attached, the upper portion of the ear hooking portion 30 is more strongly pulled backward, and the bending portion 81 can be bent more sufficiently.

In addition, the slits 54 are largely opened in an inverted V-shape or an inverted U-shape, so that each heating element 20 can be fitted well to the region from the eyes of the face to the cheek.

Here, the state in which the main body portion 10 and the pair of ear hook portions 30 are spread flatly refers to a state in which the entire heating tool 100 is spread as flat as possible and the entire heating tool 100 is naturally mounted (however, the heating tool In the case where the heating tool 100 is provided with a three-dimensional structure portion 60 to be described later, the strain is made uniform throughout the three-dimensional structure portion 60 without applying a tension for stretching 100 around.
The vertical dimension H of the ear hooking opening 30a is the size of the ear hooking opening 30a in the direction orthogonal to the alignment direction (left and right direction in FIG. 1) of the pair of ear hooking portions 30, that is, the upper end of the ear hooking opening 30a. And the lower end (the difference between the lower end of the ear hooking slit lower portion 31a and the upper end of the ear hooking slit upper portion 31b).
The distance W can be, for example, the distance between the pair of ear hooks 30 at the same height position as the center 20 c in the vertical direction of the heat generating body 20. The distance between the pair of ear hooks 30 is, as shown in FIG. 1, the distance between the farthest portions of the pair of ear hook openings 30a at the same height as the center 20c in the vertical direction of the heating element 20. (Refer also to FIG. 7 (a) and FIG. 7 (b) which are mentioned later as a modification).

H / L is 1 or less.

The heating implement 100 is sealed in a packaging bag (not shown) made of, for example, a packaging material having an oxygen barrier property before use. When the heating tool 100 is taken out of the packaging bag at the time of use, the heat generating material 23 of the heat generating body 20 comes into contact with oxygen in the air to generate heat and generate steam (vapor thermal). And, it is discharged to the outside through the first sheet 51.
Therefore, when the user wears the heating implement 100, the water vapor is supplied to the user's face. This makes it possible to warm the user's face with a steaming towel. Thus, the heating implement 100 according to the present embodiment is a steam heating implement.
In order to attach the heating implement 100, the first sheet 51 of the main body 10 is on the face side, and the first portion 11 and the second portion 12 are applied to the left and right eyes 75 to the cheek 76, respectively. The hooks 30 are hooked on the left and right ears 74 respectively.

Here, an example of a method for forming the three-dimensional structure 60 will be described with reference to FIG.
The heating implement-constituting sheet 120 shown in FIG. 5 is a material for producing the heating implement 100. The heating tool-constituting sheet 120 is different from the heating tool 100 in that the pair of left and right planned joining portions 56 shown in FIG. 5 are not joined to each other, and in the other points, the configuration is the same as the heating tool 100. It is done.
For example, as shown in FIG. 5, by forming a V-shaped cutout portion 55 at the upper edge of the widthwise central portion of the main body portion 10 in the first sheet 51 and the second sheet 52, the heating tool configuration is provided. The sheet 120 is obtained. Then, the upper connection portions 61b of the three-dimensional structure 60 are formed as shown in FIG. 1 and FIG. 2 by mutually joining a pair of planned joining portions 56 which are the left and right edges of the notch shaped portion 55, The heating implement 100 can be manufactured.
The lower connection portion 61a of the three-dimensional structure 60 is, for example, a portion in which the portion on the first portion 11 side and the portion on the second portion 12 side are mutually connected in the first sheet 51 and the second sheet 52, for example. It is.

Note that the method of forming the three-dimensional structure 60 is not limited to this example, and for example, a straight line extending vertically at the upper edge of the widthwise central portion of the main body 10 in the first sheet 51 and the second sheet 52 A three-dimensional structure 60 similar to that shown in FIGS. 1 and 2 can be formed by forming a slit (not shown) in the shape of a loop and overlapping portions of the left and right sides of the slit and joining them.
Alternatively, the structure of the lower connection portion 61a and the upper connection portion 61b may be reversed to that of the present embodiment. In this case, in the first sheet 51 and the second sheet 52, the upper connecting portion 61b is originally a portion in which the portion on the first portion 11 side and the portion on the second portion 12 side are mutually connected. On the other hand, the lower connection portion 61 a is formed by mutually bonding the left and right edges of the slit connected to the upper side of the slit 54.
Alternatively, the three-dimensional structure 60 can be formed by pressing (press) on the top of the central portion in the width direction of the main body 10.
Alternatively, the three-dimensional structure portion 60 can be formed by partially forming an upper portion of the widthwise center portion of the main body portion 10 with a structure containing rubber fibers and shrinking the portion in the width direction.

The heating implement 100 preferably has, for example, a surface maximum temperature of 38 to 70.degree. The surface maximum temperature of the heating implement 100 and the amount of water vapor generation are numerical values measured as follows using the device 90 shown in FIG. The apparatus 90 shown in FIG. 6 measures a measurement chamber (volume 4 L) 91 made of aluminum, and an inflow path 92 which allows dehumidified air (humidity less than 2%, flow rate 2.1 L / min) to flow into the lower part An outlet 93 for discharging air from the upper part of the chamber 91, an inlet temperature and humidity meter 94 and an inlet flow meter 95 provided in the inlet 92, and an outlet temperature and humidity meter 96 and an outlet flow meter 97 provided in the outlet 93. And a thermometer (thermistor) 98 provided in the measurement chamber 91. As the thermometer 98, one having a temperature resolution of about 0.01 ° C. is used.

The surface maximum temperature of the heating tool 100 is measured by removing the heating tool 100 from the packaging bag at a measurement environment temperature of 30 ° C. (30 ± 1 ° C.) and positioning the face of the heating tool 100 on the face side Of the two sheets 52, the surface on the side of the first sheet 51) is placed on top in the measurement chamber 91, and a thermometer 98 having a metal ball (mass of 4.5 g) is placed on it and measured.
In this state, dehumidified air is allowed to flow from the lower part, and the difference in absolute humidity before and after air flows into the measurement chamber 91 is determined from the temperature and humidity measured by the inlet temperature and humidity meter 94 and the outlet temperature and humidity meter 96. From the flow rates measured by the flow meter 95 and the outlet flow meter 97, the amount of water vapor released by the heating implement 100 is calculated.
The surface temperature in the present specification means the highest temperature reached on the surface of the heating tool 100 after the heating tool 100 is taken out from the packaging bag, that is, after the generation of water vapor is started, Is the total amount of the amount of water vapor measured up to 10 minutes after the temperature tool 100 is removed from the oxygen blocking bag, that is, when the generation of water vapor is started.

According to the embodiment as described above, the main body portion 10 of the heating tool 100 is formed in a size capable of covering the region from the eyes to the cheek in the face, and the lateral width direction central portion of the main body portion 10 A slit 54 extending upward from the lower edge of the main body 10 is formed, and a three-dimensional structure that causes the upper part to have a convex curved shape toward the front at the upper part in the lateral width direction central part of the main body 10 The portion 60 is formed.
Therefore, the face can be widely heated by the heating element 20 in a state where the body part 10 covers the eyes to the cheek in the face. Further, outside air can be smoothly introduced between the lower portion of the main body portion 10 and the face from the lower side of the main body portion 10, and the external air can be supplied to the heat generating body 20 to cause the heat generating body 20 to generate heat. And since it becomes easy to closely contact or approach the upper edge in the lateral width direction central part of the main body 10 to the forehead, warm air escapes upward from the gap between the upper edge and the face in the lateral width direction central part of the main body 10 This warm air can be filled between the main body 10 and the face. Therefore, the wide area of the face can be warmed more sufficiently.

Hereinafter, modified examples of the above embodiment will be described.

As in the modified example 1 shown in FIG. 7A and the modified example 2 shown in FIG. 7B, the ear hooking opening 30a may be the ear hooking slit 31 having a shape having a lateral width. . In the case of the modified example 1 shown in FIG. 7A, the circumferential length L on the side far from the main body 10 in the ear hook opening 30a is the sum of the length L11 and the length L12 shown in FIG. .
Further, in the case of the second modification shown in FIG. 7B, the circumferential length L of the ear hook opening 30a on the side far from the main body 10 is based on the longitudinal axis AX2 connecting the upper end and the lower end of the ear hook opening 30a. As a length along the edge far from the main body 10, that is, a length L13 shown in FIG.

The present invention is not limited to the above-mentioned embodiment and each modification, and also includes various modifications, improvements and the like as long as the object of the present invention is achieved.

For example, although an example in which the number of three-dimensional structure parts 60 formed in the main body part 10 is one has been described above, a plurality of (for example, two) three-dimensional structure parts 60 are arranged side by side. It is good.

Further, although the example in which the main body portion 10 and the pair of ear hooking portions 30 are configured by a part of each of the series of sheets (second sheet 52) has been described above, the ear hooking portion 30 is the main body portion 10 The sheet separate from the sheet constituting the sheet may be provided on the main body portion 10 by joining the sheet constituting the body portion 10 to the sheet.

Also, the heating element 20 may be an exothermic one that does not release steam. Therefore, the heating implement 100 may not be a steam heating implement but a simple heating implement.
