Description

  The present invention relates to a thermal pad used for heating a body by heating with a microwave oven or the like.

  A thermal pad that warms the body against the body is used for thermal treatment, prevention of cold, recovery from fatigue, and the like. In recent years, there has been proposed such a thermal pad in which a granular material that can be heated by electromagnetic waves is filled in a bag and heated in a microwave oven (for example, Patent Document 1).

Japanese Patent No. 3101728

  Although the thermal pad described in Patent Document 1 can warm the body, it is difficult to physically massage the warmed portion. Even if force is applied from the back side of the thermal pad to the surface of the body with fingers or palms, the fine granular material filled inside will disperse the force around, and local force cannot be applied to the surface of the body. is there. If the thermal pad is made thinner, it becomes easier to apply a local force to the body surface, but it is not practical because the heat capacity becomes smaller and it becomes easier to cool.

  This invention is made | formed in view of this present condition, and aims at provision of the thermal pad which can massage the part currently warmed appropriately.

  The present invention is a thermal pad formed by filling a flat bag body with a plurality of granular bodies that can be heated by electromagnetic waves and a massage ball having a diameter that is at least half the thickness of the bag body.

  In such a configuration, a local force can be applied to the body surface by pressing the portion where the massage ball is positioned against the body surface with a finger or palm from the back side. That is, in the thermal pad in which only the granular material is filled in the bag body, the force applied from the back side is propagated and dispersed because the granular material is fine, and local force cannot be applied to the body surface. In the present invention, a force can be applied to the body surface from the back side of the pad without dispersing the force to the surroundings by applying a force through a massage ball much larger than the granular body. is there. For this reason, according to the thermal pad of the present invention, the heated thermal pad is applied to the body surface, and the body surface is pressed against the body surface with a finger or palm from the back side while warming the body surface, It is possible to press or hesitate the warmed portion, and to obtain a massage effect at the same time as the heat effect.

  In the present invention, since the massage balls are filled in the bag together with the granules, when the massage balls are pressed against the body surface, the granules are sandwiched between the massage balls and the cloth of the bag. Will be. For this reason, when massage is performed by pressing the massage ball, the uneven portions formed by the sandwiched granular body are pressed against the body surface, thereby strongly stimulating the body surface and higher A massage effect can be obtained.

  In addition, the thermal pad of the present invention can be deformed flexibly so as to follow the shape of the body surface by flowing the granular material filled in the bag, so even in a portion where the undulations such as the face and the shoulder are severe Can be massaged while warming up properly.

  In addition, the massage ball according to the present invention is not limited to a true sphere, and may be an ellipsoidal shape. And in this invention, when making the ball for massage into an ellipsoidal shape, what is necessary is just to comprise so that the shorter diameter of an ellipsoid may become half or more of the thickness of a bag.

  Moreover, in this invention, it is preferable that the said several granule is 1-5 mm in particle size. If the granular material has a particle size of 5 mm or less, an appropriate copying function can be exhibited in accordance with the shape of the body surface. Further, if the granule has a particle size of 1 mm or more, when the massage ball is pressed against the body surface, the granule on the surface of the ball can give an appropriate stimulus to the body surface. There is also an advantage that it is difficult to leak from the gap. On the other hand, it is desirable that the massage ball has a substantially spherical shape with a diameter of 1.5 to 3.5 cm. With this configuration, the massage ball has the size of a thumb, and is suitable for pressing the pressure points on the body surface.

  Further, in the present invention, the bag body is made of a breathable cloth, and the plurality of granular bodies have hygroscopicity and are heated by electromagnetic waves, thereby absorbing absorbed moisture as steam. It is proposed to release. In such a configuration, when the thermal pad is heated, steam is released around the thermal pad, and an effective massage can be performed while warming the body under high humidity conditions.

  As described above, according to the present invention, by pressing the massage ball toward the body surface side, it is possible to massage the portion appropriately while warming the body. Further, in the present invention, when the massage ball is pressed against the body surface, the granule sandwiched between the massage ball and the body surface stimulates the body surface, so that a higher massage effect Can be obtained. Moreover, since the thermal pad of the present invention can be flexibly deformed so as to follow the undulations on the body surface, it is possible to massage appropriately while warming relatively undulating parts such as the face and shoulders.

It is a top view which shows the thermal pad 1a of another Example.

  Embodiments of the present invention are described according to the following examples.

  As shown in FIGS. 1 and 2, the thermal pad 1 of the present embodiment has a flat shape of a heart shape in plan view. As a suitable size of the thermal pad 1, the vertical and horizontal sizes are 7 to 15 cm and the thickness is 2.5 to 4.5 cm.

  As shown in FIGS. 3 and 4, the thermal pad 1 is formed by filling a bag body 2 with a large number of granular bodies 3 and one massage ball 4. The granular body 3 and the massage ball 4 are filled in the bag body 2 with a margin so that it can flow inside the bag body 2.

  The bag body 2 is formed by sewing a general cloth having air permeability into a heart shape in a plan view. There are no compartments inside the bag body 2, and the granules 3 and the balls 4 are configured to flow freely inside. Although the kind of cloth which forms the bag body 2 is not particularly limited, it is desirable to use a heat-resistant cloth that is flexible and difficult to tear.

  The granular material 3 is a small particle having a particle diameter of about 2 to 3 mm, and a large number are filled in the bag body 2. On the other hand, the massage ball 4 is a spherical body having a diameter of about 2.5 cm, and is contained in the bag body 2 so as to be mixed with the granular body 3. The granule 3 and the massage ball 4 are made of hygroscopic ceramic that can be heated by electromagnetic waves of a microwave oven.

Below, the usage method of the said thermal pad 1 is demonstrated.
When using the heating pad 1, first, the granule 3 and the massage ball 4 made of hygroscopic ceramic are heated using a microwave oven. Although heating conditions depend on the size of the thermal pad 1, the thermal pad 1 can be heated to a sufficient temperature by heating for about several minutes in a 500 W microwave oven. At this time, the granular body 3 and the massage ball 4 are not only heated, but the moisture contained in the granular body 3 and the massage ball 4 becomes steam, and the generated steam passes through the cloth of the bag body 2. And released to the surface of the thermal pad 1.

  As shown in FIG. 5 (a), the heated thermal pad 1 can warm the body by being applied to the body surface 10 directly or from above clothing or the like. At this time, since the steam is released from the thermal pad 1, the portion to which the thermal pad 1 is applied is heated under high humidity conditions. The body part to which the thermal pad 1 is applied is not particularly limited, and examples include the neck, shoulders, face, decollete, soles, calves, and back.

  As shown in FIG. 5 (b), when the portion with the massage ball 4 is pressed against the body surface 10 from the opposite side with the thermal pad 1 applied to the body surface 10, the body is interposed via the massage ball 4. A local force can be applied to Table 10, and the body surface 10 can be pressed and massaged while the body surface 10 is warmed. In addition, if the massage ball 4 is moved along the body surface 10 in a state where the massage ball 4 is pressed against the body surface 10, it is possible to perform acupuncture massage at a location warmed by the thermal pad 1.

  Here, when the massage ball 4 is pressed against the body surface 10, as shown in FIG. 5B, the granular material between the bag body 2 and the massage ball 4 is caused by the frictional force of the fabric of the bag body 2. 3 will be sandwiched. For this reason, when massage is performed by pressing the massage ball 4, the unevenness formed by the sandwiched granular body 3 stimulates the body surface 10, and thereby the smooth surface of the massage ball 4 is formed. A stronger stimulation than pressing can be given to the body surface 10.

  Further, the thermal pad 1 can be deformed so as to follow the shape of the body surface 10 even if the part 3 is relatively undulated by the granular body 3 filled in the bag body 2 flowing inside. . For this reason, as shown in FIG. 6, the thermal pad 1 of the present embodiment can be attached to the body surface even in a undulating place such as the periphery of the nose and reliably heat the part. Moreover, the massage effect can be reliably obtained by pressing the massage ball 4 against the body surface 10 in such an attached state.

  As described above, according to the heating pad 1 of the present embodiment, it is possible to perform massage by applying a local force to the warmed portion while warming the body. And when performing a massage, a strong stimulation can be given to the body surface 10 by pressing the granular body 3 against the body surface 10 rather than pressing the massage ball 4 directly. Furthermore, since the granular body 3 flows, it is possible to perform massage while appropriately warming even a relatively undulating portion of the body surface.

  FIG. 7 shows another example of use of the thermal pad 1 of the present embodiment. In such an example of use, the heated thermal pad 1 is accommodated in a plurality of pockets 6 formed in the belt-shaped rubber band 5, and the rubber band 5 is wound around the trunk or legs to form the rubber band 5. By joining the hook-and-loop fasteners 7 and 7 provided at both ends, the rubber band 5 is fixed while being wound around the body. In such a method of use, if the rubber band 5 is wound so as to tighten the trunk or legs, the thermal pad 1 can be brought into close contact with the body surface by the elastic force of the rubber band 5, and the massage ball 4 can be pressed against the body surface.

  FIG. 8 shows a thermal pad 1a of another embodiment. In the present embodiment, three bag bodies 2 a are provided along the longitudinal direction of the belt-shaped bag body 8, and each bag body 2 a is filled with the granular material 3 and the massage balls 4. The heating pad 1a is attached to the body by heating the bag body 8 with a microwave oven and tying the strings 9, 9 provided at both ends in a state where the bag body 8 is applied to the body surface. Even in such a thermal pad 1a, a portion to be warmed can be massaged appropriately by pressing the massage balls 4 filled in each bag 2a against the body surface in a state of being applied to the body surface. Thus, the thermal pad of the present invention is not limited to a single bag, but can also be composed of a plurality of bags.

  In addition, the thermal pad of this invention can add a various change in the range which does not deviate from the summary of not only the form of the said Example but this invention. For example, the heating pad of the present invention is not limited to a dedicated product that is heated by electromagnetic waves of a microwave oven, and may be heated by other heating means. In addition to warming the body, the body may be cooled by a refrigerator or the like and then applied to the body surface to cool the body. Further, in the above embodiment, one massage ball is filled in one bag, but two or more massage balls may be filled in one bag.
