Description

  The present invention relates to a warming tool for applying thermal stimulation to acupoints of the body, and more particularly to a warming tool used by warming in a microwave oven.

  Traditionally, acupuncture has been used for the treatment of stiff shoulders, low back pain, neuralgia, and the like. Hyperthermia is performed by placing a bowl directly on the position of the acupoint on the meridian that is stretched around the body and applying thermal stimulation to the acupuncture point.

  As this type of thermotherapy, there is widely known a method of applying heat stimulation to the acupuncture point by attaching mogusa to the position (affected part) of the body's acupuncture point and igniting and burning the mogosa. On the other hand, recently, a heating device that contains a heating element that generates heat when irradiated with microwaves in a container with excellent heat resistance can be used for acupoints so that thermotherapy can be easily performed without using fire. A method of applying thermal stimulation is also known (see, for example, Patent Document 1).

  In the warming tool of Patent Document 1, the heating element is heated to a predetermined temperature with a microwave oven, and then the container is brought into contact with the affected part and held for a predetermined time, so that the heat stored in the heating element is passed through the container to the affected part. Reportedly.

JP 59-206480 A

  However, in the warming tool of Patent Document 1, the heating element is only covered with the container, and the container is in contact with the heating element at the contact surface to be brought into contact with the body and the side surface for gripping the container. Therefore, when the heating device is heated by the microwave oven, the heat generated from the heating element is directly transmitted to the container, and the temperature of the heating device is greatly increased as the heating element is heated. The container becomes very hot. Therefore, when taking out a warming tool from a microwave oven after heating with a microwave oven, there exists a problem that a storage tool is too hot and a user cannot hold a storage tool.

  The present invention has been made by paying attention to the above-described problems, and even when immediately after heating by a microwave oven or the like, the container is not so hot, and the user can easily grab the container and hold the microwave oven. An object of the present invention is to provide a warming tool that can be taken out from a hot spring.

  The above object of the present invention is to provide a heating element that generates heat when irradiated with microwaves, a cylindrical container that has bottoms at both ends and accommodates the heating element therein, and at least the heating element or the container. This is achieved by a warming tool provided on one side and provided with a plurality of ribs that form spaces between the outer peripheral surface of the heating element and the inner peripheral surface of the container.

  In the warming tool having the above configuration, it is preferable that three or more ribs are arranged at equal intervals along the circumferential direction of the outer peripheral surface of the heating element or the inner peripheral surface of the container.

  Moreover, it is preferable that the 1st protrusion is provided in one said bottom part of the said container.

  In addition, it is preferable that a second protrusion that sandwiches the heating element with the one bottom portion is provided on the other bottom portion of the container.

  Moreover, it is preferable that the height of the first protrusion is lower than that of the second protrusion.

  Moreover, it is preferable that the said rib is provided in the inner peripheral surface of the said container, and the groove | channel by which the said rib is fitted is provided in the outer peripheral surface of the said heat generating body.

  The container includes a bottomed cylindrical container that houses the heating element and a bottomed cylindrical cover that is attached to the container, and the cover is in contact with a bottom part that abuts the heating element. It is preferable that the container can be displaced in the axial direction so as to move between a position and a separation position where a bottom portion forms a space with the heating element.

  According to the warming tool of the present invention, since a space is formed by the rib interposed between the inner peripheral surface of the container and the outer peripheral surface of the heating element, it is generated from the heating element during heating by the microwave oven. Therefore, the temperature of the container is prevented from being significantly increased by the heat from the heating element. Therefore, the temperature of the container immediately after heating by the microwave oven does not become too high as in the conventional heating tool disclosed in Patent Document 1, and can be set to a sufficiently low temperature that does not feel so much heat. Therefore, immediately after heating by the microwave oven, the user should easily grasp the storage device and take out the heating device from the microwave oven or set it on the affected part of the body without causing burns even if it touches the storage device. Can do.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG.1 and FIG.2 has shown the internal structure of the hot water tool 1 which concerns on one Embodiment of this invention. 3 to 7 show the external appearance and internal configuration of the container 3 shown in FIGS. 1 and 2, and FIGS. 8 to 10 show the external appearance and internal configuration of the cover 4 shown in FIGS. Yes. In the following description, the vertical direction in FIGS. 1 and 2 is referred to as the vertical direction.

  The warming tool 1 according to the present embodiment includes a heating element 2 that generates heat upon receiving microwave irradiation, and a cylindrical container 5 that has bottom portions 30 and 40 at both ends and accommodates the heating element 2 therein. I have. The heating tool 1 generates heat by, for example, heating the heating element 2 to a predetermined temperature using a microwave oven, and then holding the bottom 40 of the container 5 in contact with the position (affected part) of the body for a predetermined time. A heat stimulus is given to the acupuncture point by heat emitted from the body 2. In addition, when making one bottom part 40 of the container 5 contact an affected part, although illustration is abbreviate | omitted, the seal | sticker which has adhesiveness or adhesiveness on both surfaces is previously affixed on an affected part, and one side of the container 5 is attached to this seal | sticker. By sticking the bottom part 40, the container 5 can be held for a long time without detaching from the affected part.

  The heating element 2 contains a heat generating material that absorbs microwaves and generates heat as a main component. Examples of the heat generating material described above include manganese-zinc-based, nickel-zinc-based, magnesium-nickel-based, magnesium-copper-based ferrite, silicon carbide, carbon material, silicon dioxide, phenol resin, urea resin, melanin resin, Examples thereof include polymer compounds such as polyethylene glycol and polyvinyl chloride. This heat-generating material powder, granules, lumps or liquid / viscous material is mixed in a heat-resistant binder such as silicone rubber or fluoro rubber to disperse it uniformly, and if necessary, prevent aging of the dispersant and rubber. The heating element 2 is manufactured by forming a composition to which an agent and an antioxidant are added into an arbitrary shape such as a cylindrical shape and heat-treating it. Such a heat generating body 2 is a conventionally well-known thing, For example, the thing of Unexamined-Japanese-Patent No. 2012-57829 and Unexamined-Japanese-Patent No. 2010-6617 can be used conveniently. It is preferable that the heat generating body 2 is produced so that it may be heated up to about 50 degreeC-120 degreeC by the heating by a microwave oven. Thereby, the temperature of one bottom 40 of the container 5 that plays a role of transferring heat to the affected part of the body is preferably about 50 ° C. to 80 ° C., which is the maximum temperature of the thermotherapy with mogusa.

  In this embodiment, the container 5 includes a bottomed cylindrical container 3 that houses the heating element 2 and a bottomed cylindrical cover 4 attached to the container 3, and the bottom 40 of the cover 4 is attached to the affected part of the body. , The heat generated from the heating element 2 is transmitted to the affected area, and the acupuncture points are thermally stimulated. The container 3 and the cover 4 are formed of a material that transmits microwaves even when irradiated with microwaves, and the container 3 and the cover 4 themselves do not generate heat. For example, in addition to ceramics and glass fiber, nylon, polyethylene, polystyrene It is formed by molding a hard synthetic resin having heat resistance such as polypropylene. Among these, polypropylene is preferable from the viewpoint of heat resistance and moldability. Both the container 3 and the cover 4 have a bottomed cylindrical shape having an opening at one end and a bottom portion 30, 40 at the other end, and the disk-shaped bottom portions 30, 40 are cylindrical side wall portions 31. , 41 has a larger outer shape.

  The container 3 includes a bottom portion 30 and a side wall portion 31, and the heating element 2 is accommodated in the internal space. An annular second protrusion 32 protruding from the inner surface of the bottom 30 is integrally provided on the bottom 30 of the container 3, and the heating element 2 is supported on the bottom 30 via the second protrusion 32. In addition, on the outer surface opposite to the inner surface of the bottom portion 30, a recessed surface 35 that is smoothly recessed in a dish shape at the center is formed. The recessed surface 35 follows the shape of the abdomen of the fingertip of a human hand. By bringing the fingertip into contact with the recessed surface 35, the container 3 is pushed toward the cover 4 as will be described later, and the cover 4 When the container 3 is slid with respect to the container 3, the container 3 is easily pushed. On the other hand, since the bottom portions 30 and 40 of the container 3 and the cover 4 are formed larger than the side wall portions 31 and 41, the bottom portions 30 and 40 are held when the cover 4 is slid away from the container 3. To be a hand, you can easily pull them apart using both hands.

  The side wall 31 of the container 3 has a slightly larger outer diameter than the heating element 2, and the tip (lower end) of the side wall 31 is chamfered so that it can be smoothly inserted into the side wall 41 of the cover 4. Yes. A plurality of ribs 33 extending in the axial direction (vertical direction) from the bottom 30 are integrally provided on the inner peripheral surface of the side wall 31 at a plurality of locations. The rib 33 abuts on the outer peripheral surface of the heating element 2 supported on the second protrusion 32, thereby forming a space 34 between the outer peripheral surface of the heating element 2 and the inner peripheral surface of the side wall portion 31. . Also, the rib 33 functions as a positioning for positioning the heating element 2 supported on the second protrusion 32 at a predetermined position without moving by contacting the outer peripheral surface of the heating element 2. In order to make the ribs 33 function as such positioning, it is preferable that at least two, preferably three or more ribs 33 are arranged on the inner peripheral surface of the side wall portion 31 at equal intervals along the circumferential direction. . In the present embodiment, the four ribs 33 are arranged at intervals of 90 degrees. Even when only two ribs 33 are provided, a groove (not shown) extending in the axial direction (vertical direction) is formed on the outer peripheral surface of the heating element 2, and the rib 33 is fitted into this groove. Then, the heating element 2 can be positioned at a fixed position without moving reliably. Even when three or more ribs 33 are provided, the grooves described above may be formed on the outer peripheral surface of the heating element 2. In the present embodiment, the rib 33 is formed in a tapered shape with a tapered tip and is connected to the inner peripheral surface of the side wall portion 31. However, the rib 33 is not necessarily formed in a tapered shape. The tip (lower end) may extend to the tip of the side wall 30.

  A space 34 between the outer peripheral surface of the heating element 2 and the inner peripheral surface of the side wall portion 31 functions as a heat insulating layer due to the presence of air, and is generated from the heating element 2 when the heating device 1 is heated by the microwave oven. The heat is directly transmitted to the side wall portion 31, thereby preventing the temperature of the side wall portion 31 from becoming high due to the heat from the heating element 2. Thereby, the temperature of the side wall part 31 of the container 3 after heating by the microwave oven is in a range of about 30 ° C. to 60 ° C. which is a temperature range in which the user can sufficiently grasp the side wall part 31 without feeling so hot. Can be set. In addition, since the heat generated from the heating element 2 can be efficiently stored in the container 3 without passing through the side wall portion 31 and out of the container 3, the heat retaining property of the heating element 2 can be improved. The height H1 of the rib 33 is preferably 0.2 mm or greater and 1.0 mm or less, and is approximately 0.5 mm in the present embodiment. This is because if the height H1 of the rib 33 is lower than 0.2 mm, the temperature of the side wall portion 31 is likely to rise due to the heat generated from the heating element 2, and the temperature of the side wall portion 31 may become high.

  Note that the second protrusion 32 on the bottom portion 30 of the container 3 also forms a space 39 between the upper end surface of the heating element 2 and the inner surface of the bottom portion 30, similarly to the ribs 33 on the side wall portion 31. It functions as a heat insulating layer due to the presence of air, and heat generated from the heating element 2 is directly transmitted to the bottom 30 when the heating device 1 is heated by the microwave oven, and the temperature of the bottom 30 is caused by the heat from the heating element 2. High temperature is prevented. Thereby, the temperature of the bottom part 30 of the container 3 after heating by a microwave oven can also be set to the range of about 50 degreeC-80 degreeC, and when a user slides the cover 4 with respect to the container 3, a user However, it becomes possible to touch the hollow surface 35 of the bottom part 30 without feeling so hot. The height H2 of the second protrusion 32 is preferably not less than 0.5 mm and not more than 6.0 mm, and is about 1.0 mm to 4.0 mm in this embodiment. Note that the second protrusion 32 of the bottom 30 of the container 3, as will be described later, strongly presses the heating element 2 against the bottom 40 of the cover 4 when the cover 4 is slid toward the container 3. Also plays the role of sandwiching the heating element 2 with the bottom 40 of the four.

  The side wall 31 of the container 3 is notched in the predetermined length axial direction from the tip (lower end), thereby providing a pair of left and right concave grooves 36, and one end of the side wall 31 between the concave grooves 36. A locking piece 37 that is cantilevered is provided. The locking piece 37 and the pair of left and right concave grooves 36 are provided at at least two positions on the side wall portion 31, and are arranged at equal intervals along the circumferential direction of the side wall portion 31. A protruding portion 38 is provided at the tip (lower end) of the locking piece 37 so as to protrude outward. In the present embodiment, the projecting portion 38 has a first projecting portion 38A extending vertically in the axial direction and a pair of second projecting portions provided on both sides of the first projecting portion 38A at the center of the width of the locking piece 37. 38B. The first convex portion 38A is formed in a triangular shape in a right-angled cross-sectional view in which the height protruding from the outer surface of the locking piece 37 increases upward, and the second convex portion 38B is more than the first convex portion 38A. The height is low, and the top is formed in a mountain shape with a round top in a cross-sectional view so that the first protrusion 38A and the end are aligned. The convex portions 38 (first convex portion 38A and second convex portion 38B) are engaged with and disengaged from upper and lower concave portions 44 and 45 formed on a side wall portion 41 of the cover 4 described later. In addition, the shape of the convex part 38 (1st convex part 38A and 2nd convex part 38B) may be various shapes, if it engages / disengages with the upper and lower recessed parts 44 and 45 of the side wall part 41 of the cover 4.

  The cover 4 includes a bottom 40 and a side wall 41, the side wall 41 has a larger outer diameter than the side wall 31 of the container 3, and the side wall 31 of the container 3 can be inserted into the internal space of the cover 4. In addition, the cover 4 can be displaced in the axial direction with respect to the container 3 by sliding the cover 4 in the axial direction. Thereby, the cover 4 has a contact position (shown in FIG. 1) where the bottom portion 40 contacts the heating element 2, and a separation position (FIG. 2) where the bottom portion 40 forms a space 42 between the heating element 2. Move between. The tip (lower end) of the side wall 41 is chamfered so that the side wall 31 of the container 3 can be inserted smoothly.

  The bottom 40 of the cover 4 is integrally provided with an annular first protrusion 43 protruding from the inner surface of the bottom 40, and when the cover 4 is slid toward the container 3 to be in the contact position, the bottom 40 The first protrusion 43 comes into contact with the heating element 2. Since the bottom 40 of the cover 4 is a part that contacts the affected part of the body when using the warming tool 1 and transmits heat generated from the heating element 2 to the affected part, if the height H3 of the first protrusion 43 is too high, The heat generated from the heating element 2 is not sufficiently transmitted to the entire bottom 40, and the heat transfer effect to the affected area is reduced. Therefore, the height H3 of the first protrusion 43 is preferably 0.1 mm or more and 0.5 mm or less so that the heat from the heating element 2 is sufficiently transmitted to the entire bottom portion 40, and in this embodiment, about 0.3 mm. It is. The height H3 of the first protrusion 43 is preferably lower than the height H2 of the second protrusion 32, and the ratio of H2 and H3 is preferably 3 or more. Further, the first protrusion 43 is preferably an annular shape thicker than the second protrusion 32 so that heat from the heating element 2 is sufficiently transmitted to the entire bottom portion 40. In the present embodiment, the first protrusion 43 has an annular shape. While the thickness is about 1 mm, the thickness of the ring of the second protrusion 32 is about 2.5 mm.

  On the side wall 41 of the cover 4, recesses 44 and 45 are provided vertically at positions corresponding to the contact position and the separation position described above. In this embodiment, the recesses 44 and 45 are formed by through holes that penetrate the side wall 41. A pair of upper and lower concave portions 45, 45 is provided in a number corresponding to the convex portions 38 of the side wall portion 31 of the container 3, and in this embodiment, two locations are equally spaced along the circumferential direction of the side wall portion 41 of the cover 4. Is arranged. The upper and lower recesses 44 and 45 are connected by a long hole 46 extending in the vertical direction penetrating the side wall 41. The lateral width of the long hole 46 is the same as the lateral width of the first convex portion 38A of the side wall 31 of the container 3, and when the cover 4 slides in the axial direction with respect to the container 3, The part 38A passes through. Further, the lateral width of the concave portions 44 and 45 is wider than the lateral width of the long hole 46 and is the same as the lateral width of the convex portions 38 (the first convex portion 38A and the second convex portion 38B) of the side wall portion 31 of the container 3. The cover 4 can be fixed at the above-described contact position and separation position by the protrusions 38 (the first protrusion 38A and the second protrusion 38B) being hooked and locked in the recesses 44 and 45, respectively. When the cover 4 slides in the axial direction with respect to the container 3, the second convex portion 38 </ b> B of the container 3 abuts on both sides of the long hole of the side wall 41 of the cover 4, but the locking piece 37 is slightly The second projection 38B bends inward and rides over both sides of the long hole of the side wall 41 of the cover 4 described above, so that sliding is possible.

  Next, the usage method of the warming tool 1 of the said structure is demonstrated. First, the cover 4 is moved to the separation position shown in FIG. In this state, the heating tool 1 is placed on the microwave oven with the cover 4 facing down and heated for a predetermined time. As a result, the heating element 2 generates heat upon receiving the microwave irradiation, and the temperature is raised to a predetermined temperature. At the time of heating by the microwave oven, the cover 4 is in a separated position, the bottom 40 of the cover 4 is not in contact with the heating element 2, and a space 42 is formed between the heating element 2. Since the space 42 functions as a heat insulating layer due to the presence of air, the heat generated from the heating element 2 is directly transmitted to the bottom 40 of the cover 4 during heating by the microwave oven, and the bottom 40 is heated by the heat from the heating element 2. Is prevented from significantly rising. Therefore, the temperature of the bottom 40 of the cover 4 after heating by the microwave oven does not become high, and can be suppressed to a relatively low temperature of about 30 ° C. to 50 ° C.

  Furthermore, spaces 34 and 39 are also interposed between the bottom 30 and the side wall 31 of the container 3 and the heating element 2 and similarly function as a heat insulating layer due to the presence of air, thereby generating heat during heating by a microwave oven. The heat generated from the body 2 is directly transmitted to the bottom 30 and the side wall 31 of the container 3, and the temperature of the bottom 30 and the side wall 31 is prevented from being significantly increased by the heat from the heating element 2. Therefore, since the temperature of the bottom part 30 and the side wall part 31 of the container 3 after heating by a microwave oven can be suppressed to the low temperature which can touch enough, without feeling so hot about 30 to 60 degreeC, a user is When the heating tool 1 is taken out of the microwave oven, the bottom part 30 and the side wall part 31 of the container 3 and the side wall part 41 of the cover 4 positioned outside the side wall part 31 of the container 3 can be hotly touched. It is not difficult.

  And when the heating by a microwave oven is complete | finished, the warmth tool 1 is taken out from a microwave oven, and it moves to the contact position shown in FIG. As a result, the bottom 40 of the cover 4 comes into contact with the heating element 2, and heat generated from the heating element 2 is directly transmitted to the bottom 40. Then, a sticky or adhesive seal is attached to both sides of the affected part of the body, and the bottom 40 of the cover 4 is attached to this seal and held for a long time, so that the heat generated from the heating element 2 is covered by the cover 4. It can be transmitted to the affected area through the bottom 40 of the body, and heat stimulation can be given to the acupoint.

  According to the warming tool 1 having the above configuration, the spaces 34 and 39 are formed by the ribs 33 and the second protrusions 32 interposed between the side wall portion 31 and the bottom portion 30 of the container 3 and the heating element 2. Immediately after the heating by the microwave oven, the temperature of the side wall 31 and the bottom 30 of the container 3 is slightly higher than that before the heating by the microwave oven, but becomes too high as in the conventional heating device of Patent Document 1. The temperature can be low enough not to feel so much heat. Therefore, the user can easily touch the side wall portion 31 and the bottom portion 30 of the container 3 and further the side wall portion 41 of the cover 4 immediately after heating by the microwave oven without causing burns or the like. The warming tool 1 can be taken out of the microwave oven and set on the affected part of the body, or the container 3 can be pushed and slid with respect to the cover 4.

  Moreover, according to the warming tool 1 of the said structure, although the temperature of the bottom part 40 of the cover 4 contacted with a body after heating with a microwave oven also rises a little from before the heating with a microwave oven, patent of a prior art It does not become too high like the contact surface of the warming tool in Document 1, and gradually rises in temperature upon receiving heat from the heating element 2, and gradually reaches a maximum temperature after a predetermined time. The temperature goes down. This temperature course is similar to the temperature course of Mogusa that has been widely used for thermotherapy. In other words, in the thermotherapy with mogusa, the mogusa does not have a high temperature immediately after the fire is lit, and heat is transferred to the affected area by gradually raising the temperature over time, and the temperature is the highest in about 2 to 5 minutes. However, in the warming tool 1 having the above-described configuration, the cover 4 is attached to the container 3 so that at least a part of the bottom 40 can be brought into contact with and separated from the heating element 2, Thermal stimulation equivalent to the thermal stimulation by the above-mentioned mogusa can be given to the acupuncture point, and the thermotherapy similar to the thermotherapy by the mogusa can be given to the user.

  As mentioned above, although one Embodiment of this invention was described, the specific aspect of this invention is not limited to the said embodiment. For example, in the above embodiment, the first protrusion 43 of the bottom portion 40 of the cover 4 is formed in an annular shape in plan view, but is not necessarily formed in an annular shape, and the outer shape is a rectangular or polygonal frame. In addition to the shape, it may be formed in a flat shape in which the hollow interior of the frame or ring is filled. Further, the first protrusion 43 is not necessarily provided.

  Moreover, in the said embodiment, although the cyclic | annular 2nd processus | protrusion 32 is provided in the bottom part 30 of the container 3, it does not necessarily need to be formed cyclically | annularly, besides the frame shape of a rectangular shape or a polygonal shape, You may form in the flat shape with which the hollow inside of the frame and the ring was filled. A plurality of second protrusions 32 may be provided. Further, the second protrusion 32 is not necessarily provided.

  Moreover, in the said embodiment, although the rib 33 is provided in the side wall part 30 of the container 3, the shape of the heat generating body 2 is changed, and the inner peripheral surface of the side wall part 31 of the container 3 is changed to the outer peripheral surface of the heat generating body 2. The rib which contacts with may be provided integrally.

  Moreover, in the said embodiment, although the recessed parts 44 and 45 are provided in the side wall part 41 of the cover 4, and the convex part 38 is provided in the side wall part 31 of the container 3, the convex part 38 is provided in the side wall part 41 of the cover 4 in a container. Concave portions 44 and 45 may be provided in the three side wall portions 31. Moreover, although the convex part 38 is comprised from 38 A of 1st convex parts and the 2nd convex part 38B, you may be comprised only by 38 A of 1st convex parts. Further, the cover 4 that slides with respect to the container 3 is fixed to the contact position and the separation position by the concave portions 44, 45 and the convex portion 38, respectively, but the cover 4 is fixed to the contact position by using other means. And may be fixed at the separation position.

  In the above embodiment, the cover 4 is slid in the axial direction to displace the cover 4 in the axial direction with respect to the container 3, but means for displacing the cover 4 in the axial direction with respect to the container 3 is provided. However, the present invention is not limited to this. For example, a female screw is formed on the inner peripheral surface of the cover 4 and a male screw is formed on the outer peripheral surface of the container 3. The male screw and the female screw are screwed together, and the cover 4 is screwed into the container 3. To be attached to. Then, the cover 4 may be displaced in the axial direction of the container 3 along with the rotation by rotating the cover 4 in the forward / reverse direction with respect to the container 3.

  In the above embodiment, the cover 4 is displaced in the axial direction with respect to the container 3 so that at least a part of the bottom 40 of the cover 4 can be brought into contact with and separated from the heating element 2. By attaching the cover 4 to the container 3 in a detachable manner, at least a part of the bottom 40 of the cover 4 can be brought into contact with and separated from the heating element 2. That is, when heating the warming tool 1 with a microwave oven, the cover 4 is removed from the container, and only the container 3 is heated with the microwave oven. The effect similar to that of the above embodiment can also be obtained by attaching the cover 4 to the container 3 after heating by the microwave oven and bringing the bottom portion 40 of the cover 4 into contact with the heating element 2.

  Moreover, in the said embodiment, although the container 3 and the cover 4 are cylindrical shapes, various shapes, such as a rectangular tube shape, may be sufficient.

  Moreover, in the said embodiment, although the container 5 is comprised by the container 3 and the cover 4, you may be comprised by the single member.

  Hereinafter, the present invention will be described in more detail based on examples and comparative examples. However, the present invention is not limited to the following examples.

After heating, the heating tool 1 was taken out of the microwave oven, and the temperature change of the side wall 31 of the container 3 was measured. Further, as Comparative Example 1, the basic configuration is the same as that of the warming tool 1 shown in the above embodiment, but the side wall 31 of the container 3 is not provided with the rib 33, and the side wall 31 of the container 3 and the heat generation. It heated with the microwave oven in the state which the body 2 contact | abutted, the heating tool 1 was taken out from the microwave oven after the heating, and the temperature change of the side wall part 31 of the container 3 was measured. The heating time by the microwave oven (700 W) was 60 seconds, and the temperature of the heating element 2 immediately after taking out the heating tool 1 from the microwave oven was about 90 ° C. The temperature of the side wall 31 of the container 3 is measured at room temperature (about 25 ° C.) at the place where the temperature sensor (AM-8000E manufactured by Anritsu Keiki Co., Ltd.) is installed. Three side wall portions 31 were placed on the temperature sensor and measured. In the temperature measurement, as shown in FIG. 2, the temperature of the side wall 31 of the container 3 was measured in a state where the cover 4 was slid away from the container 3. The measured temperature change of the side wall part 31 of the cover 3 of Example 1 and Comparative Example 1 is shown in FIG. In addition, the container 3 and the cover 4 of the warming tool 1 are made of polypropylene in both Example 1 and Comparative Example 1, and the heating element 2 is made of ferrite powder as a main component. Moreover, the temperature measured by the temperature sensor at the measurement start time (0 minutes) indicates room temperature (about 25 ° C.).

  According to FIG. 11, in Comparative Example 1, immediately after the start of measurement, the measured temperature jumps to 60 ° C. or higher, so that the temperature of the side wall 31 of the container 3 immediately after taking out the heating tool 1 from the microwave oven is 60. It is confirmed that the temperature is higher than ℃. Then, it is confirmed that the temperature reaches about 70 ° C., which is the maximum temperature, in only about 15 seconds thereafter. On the other hand, in Example 1, the measurement temperature immediately after the start of measurement is about 40 ° C., so that the temperature of the side wall 31 of the container 3 immediately after taking out the warming tool 1 from the microwave oven becomes very high. It is confirmed that it is not. Further, the subsequent temperature rise is more gradual than in Comparative Example 1, and the temperature of the side wall 31 of the container 3 reaches the maximum temperature (about 55 ° C.) after about 30 seconds, and the maximum temperature is also It is confirmed that it is lower than Comparative Example 1. As described above, the warming tool 1 of Example 1 and Comparative Example 1 are both formed of the same material. However, according to the warming tool 1 of Example 1, when heated by the microwave oven, By forming the space 34 between the heating element 2 and the rib 33, the temperature of the side wall 31 of the container 3 immediately after taking out from the microwave oven can be suppressed to a low temperature. Therefore, when the warming tool 1 is taken out from the microwave oven, even if the user grasps the side wall 31 of the container 3, the user does not feel so hot and grasps the side wall 31 of the container 3 to take out the warming tool 1 from the microwave oven. It can be seen that it can be set.

  Next, as Example 2, in the warmth tool 1 shown in the above embodiment, the bottom 40 (first protrusion 43) of the cover 4 is not brought into contact with the heating element 2 but separated from the heating element 2 ( 2), the heating tool 1 was taken out of the microwave oven, and the temperature change of the bottom 40 of the cover 4 was measured. Moreover, as a comparative example 2, in the heating device 1 shown in the above embodiment, in a state where the bottom 40 (first protrusion 43) of the cover 4 is in contact with the heating element 2 (shown in FIG. 1), After heating, the heating tool 1 was taken out of the microwave oven, and the temperature change of the bottom 40 of the cover 4 was measured. The heating time by the microwave oven (700 W) was 60 seconds, and the temperature of the heating element 2 immediately after taking out the heating tool 1 from the microwave oven was about 90 ° C. The temperature of the bottom 40 of the cover 4 is measured at room temperature (about 25 ° C.) at the place where the temperature sensor (AM-8000E manufactured by Anritsu Keiki Co., Ltd.) is installed. The bottom 40 was placed on a temperature sensor and measured. In Example 2, the temperature was measured in a state where the cover 4 was slid and the bottom 40 of the cover 4 was in contact with the heating element 2 after the heating tool 1 was taken out of the microwave oven. The measured temperature change of the bottom 40 of the cover 4 of Example 2 and Comparative Example 2 is shown in FIG. The container 3 and the cover 4 of the warming tool 1 are made of polypropylene in both Example 2 and Comparative Example 2, and the heating element 2 is made of ferrite powder as a main component. Moreover, the temperature measured by the temperature sensor at the measurement start time (0 minutes) indicates room temperature (about 25 ° C.).

  According to FIG. 12, in the comparative example 1, immediately after the start of measurement, the measured temperature jumps to 60 ° C. or more, whereby the temperature of the bottom 40 of the cover 4 immediately after taking out the heating tool 1 from the microwave oven is 60 ° C. It is confirmed that the temperature is higher than the above. After that, the temperature rises rapidly, and it is confirmed that the temperature of the bottom 40 of the cover 4 gradually decreases after reaching the maximum temperature (about 68 ° C.) in only about 30 seconds. . On the other hand, in Example 2, the measurement temperature immediately after the start of measurement is about 40 ° C., so that the temperature of the bottom 40 of the cover 4 immediately after taking out the heating device 1 from the microwave oven is very high. It is confirmed that there is not. Then, the temperature rise thereafter is more gradual than that of the comparative example, and the temperature of the bottom 40 of the cover 4 reaches the maximum temperature (about 63 ° C.) after about 1 minute, and then gradually decreases. It is confirmed that As described above, both the heating tool 1 of Example 2 and Comparative Example 2 are formed of the same material. However, according to the heating tool 1 of Example 2, the bottom 40 of the cover 4 is heated when heated by the microwave oven. By keeping away from the body 2, the temperature of the bottom 40 of the cover 4 immediately after taking out from the microwave oven, that is, immediately after the start of the thermotherapy, can be suppressed to a low temperature, and until the maximum temperature is reached. It is possible to delay the time. Therefore, since the temperature course of the bottom 40 of the cover 4 can be similar or equivalent to the temperature course of the moxa, it can be seen that the user can perform a thermotherapy similar to or equivalent to the thermotherapy by the moxa.
