JP 11-1111515 A

  However, in the magnetic body, since the magnet portion and the covering portion are formed of different materials, the magnet portion and the covering portion do not sufficiently adhere to each other, and the magnetic force generated from the magnet portion to the outside is not sufficient. While management becomes difficult, the magnetism from a magnet part may not be made to act on a body uniformly.

  In view of such circumstances, an object of the present invention is to provide a magnetic treatment instrument that can apply magnetism to the body more uniformly.

  The invention according to claim 1 for solving the above-mentioned problems is a magnetic treatment instrument used for a necklace or the like and exerting blood circulation promoting action on the body, and is formed of a mixture of silicone rubber and magnetic powder extending in a predetermined direction. And a magnetized flexible long magnet part, and a flexible covering part that is formed of silicone rubber and covers the entire outer periphery of the magnet part. It is a characteristic (claim 1).

  According to the present invention, the magnet portion is formed of a mixture of silicone rubber and magnetic powder, and the covering portion that covers the magnet portion is formed of silicone rubber. The magnetism emitted from the magnet part to the outside can be easily made uniform. That is, since the magnetism from the magnet part can be applied uniformly to the body, the blood circulation promoting action by the magnetism can be effectively applied to the body. Further, in the present invention, as described above, since the covering portion is formed of the physiologically stable silicone rubber, even when the magnetic treatment instrument is directly brought into contact with the skin, the covering portion gives to the skin. It is possible to more reliably suppress adverse effects.

  In the present invention, the magnetic treatment instrument is preferably formed by multicolor extrusion of a mixture of silicone rubber and magnetic powder forming the magnet portion and silicone rubber forming the covering portion (claim). 2).

  In this way, the outer periphery of the magnet portion can be easily covered by the covering portion, and the magnet portion and the covering portion can be more reliably brought into close contact during extrusion.

  In the present invention, the magnetic powder is preferably a rare-earth magnet powder.

  As described above, if a rare earth magnet that is more magnetic than a conventional ferrite magnet is used as the magnetic powder, the same magnetic effect can be obtained even if the amount of the magnetic powder constituting the magnet body is reduced. Is possible. Therefore, the size of the entire instrument can be reduced while ensuring the magnetic effect.

  In addition, if the amount of magnetic powder can be reduced while ensuring the same magnetic effect as described above, the ratio of the silicone rubber in the magnet body can be reduced while maintaining the magnetic effect and size of the magnetic therapy device equivalent to the conventional one. Since it becomes possible to increase, it becomes possible to improve the elasticity of a magnet body and to improve the flexibility as the whole instrument.

  Further, in the present invention, a locking portion formed of silicone rubber at one end of the covering portion, and a cover that is formed of silicone rubber at the other end of the covering portion and is detachably locked with the locking portion. It is preferable that the engagement portion is engaged with the engagement portion, so that the covering portion has a ring shape in a state of covering the magnet body. .

  In this way, the magnetic treatment instrument can be used as a necklace, a bracelet or the like, and convenience is improved. In particular, if the locking portion and the locked portion formed on the covering portion are formed of silicone rubber in the same manner as the covering portion, it is possible to fuse the covering portion with the locking portion and the locked portion. Therefore, the locking portion and the locked portion can be easily formed on the covering portion, and the locking portion and the locked portion can be prevented from dropping off from the covering portion. become.

  As a method of manufacturing the magnetic treatment instrument as described above, the silicone rubber forming the magnet part, the magnetic powder, and the vulcanizing agent are kneaded in a first kneader and the covering part is formed.

Preferably used (claim) 5).

According to such a method, since each mixture can be sufficiently kneaded in the kneading step, mixing variation of the magnet part and the covering part is suppressed, and the magnetic effect by the magnetic powder is uniformly applied to the body or the like. It becomes possible to act on. Further, in the method, each mixture is stored in the first extruder and the second extruder in the storing step, respectively, and at the same time, the magnet portion side mixture is extruded in the extrusion step, and at the same time around the covering portion side. The mixture is extruded, and the magnet part side mixture can be easily covered with the covering part side mixture. Furthermore, in the vulcanization step, since both extruded mixtures are simultaneously vulcanized, the silicone rubber in the magnet part side mixture and the silicone rubber in the coating part side mixture can be fused, The magnet portion and the covering portion formed by these mixtures can be easily integrated. In particular, in this instrument, since both the magnet part side mixture and the covering part side mixture contain the same silicone rubber, each mixture can be vulcanized at the same time without being vulcanized under different conditions. This makes it possible to reduce the time and effort of the equipment.

  As described above, according to the present invention, it is possible to provide a magnetic treatment instrument that can cause a magnetic action to act uniformly on the body and more reliably suppress adverse effects on the skin.

  Here, it is said that the silicone rubber is physiologically stable as compared with other synthetic resins and the like, and has a relatively small adverse effect on the body. Therefore, if the magnetic part 10 is covered with the covering part 20 as described above and the covering part 20 is formed of silicone rubber, the magnetic powder adheres to the skin when the magnetic necklace 1 is brought into direct contact with the skin. Can be suppressed, and adverse effects on the skin can be more reliably suppressed.

  The said latching | locking part 22 is for latching the to-be-latched part 26 mentioned later. The locking portion 22 is formed at one end of the covering portion 20 with silicone rubber. Further, the locking portion 22 is provided with a locking projection 24 protruding outward from the covering portion 20 side, and a locking hole provided in the locking projection 24 and a locked portion 26 described later. The locked portion 26 is locked to the locking portion 22 by engaging with 28.

  The locked portion 26 is locked to the locking portion 22, and is provided at the end of the covering portion 20 opposite to the locking portion 22. The locked portion 26 is formed with a locked hole 28 that is detachably engaged with the locking protrusion 24, and the locked hole 28 and the locking protrusion 24 are engaged with each other. By doing so, the coating | coated part 20 becomes ring shape.

The magnetic necklace 1 configured as described above is fixed around the neck of the body by the engagement of the locking protrusion 24 and the locked hole 28, and the covering portion 20 covers the magnet portion 10. By bending, it adheres to the skin around the neck. And the magnetism from the said magnet part 10 acts on a body, and blood circulation promotion etc. of a body are performed. Here, in this magnetic necklace 1, it is comprised so that the magnetic force by this magnet part 10 may be set to about 50 mT.

  Next, the manufacturing method of this magnetic necklace 1 is demonstrated with reference to drawings. 3 is a schematic front view of an extrusion molding apparatus for extruding this magnetic necklace, FIG. 4 is a schematic top view of FIG. 3, and FIG. 5 is a schematic sectional view of a die used in the extrusion molding apparatus. is there. The extrusion molding apparatus includes a first kneader 31, a second kneader 32, a first extruder 41, a second extruder 42, a vulcanizer 50, take-up machines 60 and 61, and a winder 70. And are provided.

  The manufacturing method of the magnetic necklace 1 using this extrusion molding apparatus includes the following steps.

1) Mastication process This process is a process of masticating and plasticizing the millable silicone rubber forming the magnet part 10 and the covering part 20. In this process, the raw rubber of the millable silicone rubber is plasticized by being repeatedly kneaded by rollers in the first kneader 31 and the second kneader 32.

2) Kneading step This step is a step of kneading another material into the plasticized millable silicone rubber. In this step, the millable silicone rubber, the rare earth magnet powder, the ferrite magnet powder, the organic peroxide as a vulcanizing agent, and the like are charged into the first kneading machine 31, and these are uniformly distributed. To be mixed. In addition, the millable silicone rubber and an organic peroxide as a vulcanizing agent are charged into the second kneader 32 and mixed so as to be uniform.

3) Storage step This step is a step of storing each mixture kneaded in the kneading step in the first extruder 41 and the second extruder 42, respectively. In this step, the magnet part side mixture kneaded by the first kneading machine 31 is stored in the first extruder 41, and the coating part side mixture kneaded by the second kneading machine 32 is stored in the second extruder 42. Is done.

4) Extrusion Step This step is a step of extruding each mixture from the first extruder 41 and the second extruder 42. Here, the first extruder 41 and the second extruder 42 are respectively connected to a connecting portion 43 provided above the vulcanizer 50, and the connecting portion 43 has a connection as shown in FIG. A dice 43a is provided. The die 43a is provided with a cylindrical inner frame 45 and an outer frame 44 that are formed of thin plate-like members and extend vertically. The inner frame 45 is provided with an outlet of the first extruder 41. Are connected, and the outlet of the second extruder 42 is connected to a portion surrounded by the inner frame 45 and the outer frame 44.

  In this step, the magnet-unit-side mixture stored in the first extruder 41 is extruded downward from the inside of the inner frame 45 by the first extruder 41, and at the same time, the second extruder 42, the covering portion side mixture stored in the second extruder 42 is extruded downward from a portion surrounded by the inner frame 45 and the outer frame 44. Thus, each mixture is continuously extruded to the vulcanizer 50 side in a state where the magnet portion side mixture is covered with the covering portion side mixture.

5) Vulcanization step This step is a step of vulcanizing the mixture extruded from each of the extruders 41 and 42 by the vulcanizer 50. In this step, hot air of about 200 ° C. is supplied under atmospheric pressure around the magnet part side mixture coated with the coating part side mixture, and the millable silicone rubber contained in each mixture is vulcanized and cured. Let At this time, since the silicone rubber of the magnet part side mixture and the silicone rubber of the covering part side mixture are vulcanized in close contact with each other, the magnet part 10 and the covering part 20 are cured in an integrated state. Will be. In this way, in this vulcanization step, a string-like magnetic body 1a in which the covering portion 20 and the magnet portion 10 covered with the covering portion 20 are integrated is formed.

6) Winding step This step is a step of winding the string-like magnetic body 1a composed of the magnet portion 10 and the covering portion 20 discharged from the vulcanizer 50. In this step, the magnetic body 1a is pulled by the take-up machines 60 and 61 having a roller portion and is taken up by the take-up machine 70 sequentially.

7) Cutting process This process is a process of cutting the string-like magnetic body 1a wound up by the winder 70 into a predetermined length.

8) Locking part welding process This process is a process of welding the locking part 22 and the locked part 26 to the covering part 20 of the magnetic body 1a cut to the predetermined length. In this step, first, one end of the covering portion 20 is attached to the locked portion side mold 80 shown in FIG. As shown in FIG. 6, the locked portion side mold 80 has a concave portion 80 a shaped like the locked portion 26. Then, a separately molded sheet of millable silicone rubber is sandwiched between the molds 80. Thereafter, by applying a predetermined pressure to the mold 80, the sheet is formed into the shape of the locked portion 26, and the sheet is welded to one end of the covering portion 20. Similarly, the locking portion 22 is formed at the other end of the covering portion 20, thereby forming the outer shape of the magnetic necklace 1.

9) Magnetization step In this step, the magnet portion 10 is magnetized by radiating high magnetism to the magnet portion 10 covered with the covering portion 20.

  In this way, the magnet portion 10 becomes a magnet in which magnetic poles are arranged along the longitudinal direction, and the magnet necklace 1 is formed by the magnet portion 10 so that magnetism acts uniformly on the body.

As described above, according to this magnetic necklace 1, since the magnet unit 10 in which magnetic powder is mixed is coated with a coating portion 20 formed of silicone rubber, skin may adhere the magnetic powder on the skin, etc. Can be prevented from being damaged. Further, the magnet portion 10 is formed of a mixture of silicone rubber and magnetic powder, and the covering portion 20 is formed of the same silicone rubber, so that the magnet portion 10 and the covering portion 20 can be sufficiently blended. Therefore, the magnetism emitted from the magnet unit 10 to the outside can be easily uniformed, the magnetism can be easily managed, and the blood circulation promoting action by the magnetism can be effectively applied to the body. Moreover, since silicone rubber is a physiologically stable substance, it is possible to more reliably suppress adverse effects on the skin.

  Further, as described above, if a strong magnetic rare earth magnet powder is used as the magnetic powder forming the magnet portion 10, the ratio of silicone rubber in the magnet portion 10 can be increased while ensuring the magnetic effect. The flexibility of the magnetic necklace 1 can be improved. As a result, the magnetic necklace 1 that can be more closely attached to the skin can be constructed. Further, when the ratio of the silicone rubber is not increased, the magnetic necklace 1 can be reduced in size while ensuring a predetermined flexibility.

  Further, as described above, the cover portion 20 is formed of the same silicone rubber as the cover portion 20, and is detachably locked to the lock portion 22 and is formed of the silicone rubber. If the latched portion 26 is provided, it is possible to fuse the covering portion 20 with the latching portion 22 and the latched portion 26, and easily form the latching portion 22 and the like on the sheath portion 20. can do. Furthermore, it can suppress that these latching | locking parts 22 grade | etc., Remove | deviate from the coating | coated part 20. FIG.

  In addition, if the above-described method is used as a method of manufacturing the magnetic necklace 1, the covering portion side mixture is extruded at the same time as the magnet portion side mixture is extruded in the extruding step. The magnet portion 10 can be easily covered with the covering portion 20. In the vulcanization step, since the extruded coating portion side mixture and magnet portion side mixture are vulcanized at the same time, the silicone rubber in the magnet portion side mixture and the silicone rubber in the covering portion side mixture are vulcanized. And the magnet part 10 and the covering part 20 formed by the mixture thereof can be easily integrated. In particular, in this vulcanization step, each mixture can be cured simply by vulcanizing the silicone rubber contained in the magnet portion side mixture and the coating portion side mixture. That is, since each mixture can be vulcanized at the same time without being vulcanized under different conditions, it is possible to reduce labor and simplify the equipment.

  Here, in the said embodiment, although it showed about the case where the magnetic powder of the mixed magnet of a rare earth magnet and a ferrite magnet was used as magnetic powder which forms the said magnet part 10, it is not restricted to this, For example, a samarium iron nitrogen system magnet Magnetic powder such as may be used.

  In the above embodiment, the case where the mixing ratio of the magnetic powder and the silicone rubber is 7: 3 is shown, but the ratio is not limited to this. However, in view of the balance between flexibility and magnetic force, the mixing ratio of the magnetic powder and the silicone rubber is preferably about 5: 5 to 9: 1.

  Further, the diameter of the magnet part 10 and the thickness of the covering part 20 can be appropriately changed.

  Moreover, the magnetic treatment instrument according to the present invention can be used as appropriate in addition to the magnetic necklace.

  Further, paint or the like may be mixed into the covering portion 20.

Moreover, in the said embodiment, although the case where the coating | coated part 20 was formed with one type of mixture was shown, you may form with multiple types of mixtures from which a color differs. For example, as shown in FIG. 7, a die 103 a provided with a plurality of partition plates 104 a in a portion surrounded by an inner frame 105 and an outer frame 104 is used, and a plurality of extruders are further added to the second extruder 42. And a mixture of different colors may be extruded into the region partitioned by the partition plate 104a. In this case, as shown in FIG. 8, a magnetic necklace 100 in which a plurality of covering portions 20 a and 20 b having different colors is formed on the covering portion 20 can be constructed.
