Thereby, the magnetic flux from the magnet portion 10 will be applied to the user's body to exert a magnetic gas action such as blood flow promoting action on the user's body. In the magnetic gas necklace 1, the magnetic field strength from the magnet portion 10 is about 50 mT.

A method of manufacturing the above-described magnetic gas necklace 1 will be described below with reference to the drawings. Fig. 3 is a schematic front view showing an extrusion molding apparatus for extruding a magnetic gas necklace, and Fig. 4 is a top view showing the extrusion molding apparatus of Fig. 3. Figure 5 is a schematic cross-sectional view showing one of the crystal grains used in the extrusion molding apparatus. The extrusion molding apparatus comprises: a first kneading machine 31; a second kneading machine 32; a first extruder 41; a second extruder 42; a vulcanizing machine 50; two drawing machines 60, 61; A winding machine 70.

The manufacturing method of the magnetic gas necklace 1 using the pressing device includes the following steps.

(1) Crushing Step A pulverizing step is performed to pulverize and plasticize the millable type silicone for the magnet portion 10 and the sheath portion 20. In this pulverizing step, the raw rubber of the millable type silicone is repeatedly kneaded by the rolls in the first and second kneading machines 31, 32, and gradually plasticized.

(2) Kneading Step The kneading step is performed to knead the plasticized millable type of silicone and the additional material. In the kneading step, a millable type silicone, a rare earth magnet powder, a ferrite magnet powder, and a vulcanizing agent such as an organic peroxide are placed in the first kneader 31, and kneaded and uniformly mixed together to obtain a magnet. Side mixture. Further, a millable type silicone and a vulcanizing agent such as an organic peroxide are placed in the second kneader 32, and kneaded and uniformly mixed together to obtain a sheath side mixture.

Specifically, in the charging step, the magnet side mixture kneaded in the first kneader 31 is filled into the first extruder 41, and the sheath side mixture kneaded in the second kneading machine 32 is filled. To the second extruder 42.

(4) Extrusion Step A pressing step is performed to press the filled magnet side and sheath side mixture from the corresponding first and second extruders 41, 42. The first and second extruders 41, 42 are each connected to a bonding unit 43 provided on the vulcanizer 50. Specifically, the bonding unit 43 has the crystal grains 43a as shown in FIG. The die 43a includes a cylindrical inner frame 45 formed vertically extending from a thin-walled plate member, and an outer frame 44 surrounding the inner frame 45. The outlet of the first extruder 41 is coupled to the inlet of the inner frame 45 and the outlet of the second extruder 42 is coupled to the inlet of the annulus surrounded by the inner and outer frames 45,44.

In the pressing step, the first extruder 41 operates to press the magnet side mixture filled in the first extruder 41 from the outlet of the inner frame 45 downward through its inner space. At the same time, the second extruder 42 operates to press the jacket side mixture filled in the second extruder 42 downward from the outlet of the annular space surrounded by the inner and outer frames 45, 44. In this manner, the sheath side mixture is extruded in such a manner as to cover the extruded magnet side mixture, and the combined magnet side and sheath side mixture are continuously fed toward the vulcanizer 50.

(5) Vulcanization Step The one vulcanization step is performed to vulcanize the combined magnet side and sheath side mixture which is pressed from the first and second extruders 41, 42. In the vulcanization step, hot air of about 200 ° C at ambient pressure is supplied to the outer periphery of the sheath-side mixture covering the mixture on the magnet side to vulcanize and harden the millable type contained in the mixture on the magnet side and the sheath side Silicone. In this step, the silicone in the mixture on the magnet side and the silicone in the sheath side mixture are vulcanized in contact with each other. Thereby, the individual silicone rubber is hardened so that the magnet portion 10 and the sheath portion 20 are bonded together. In this manner, the string-like magnetic gas member 1a having the structure of the entire magnet portion 10 and the sheath portion 20 covering the magnet portion 10 is formed by the vulcanization step.

(6) Winding Step A winding step is performed to wind the string-shaped magnetic gas member 1a, which is discharged from the vulcanizer 50 in the form of the entire structure of the magnet portion 10 and the sheath portion 20. In the winding step, the magnetic gas members 1a are pulled by the pulling machines 60, 61 each having a drum unit, and are continuously wound by the winding machine 70.

(7) Cutting Step A cutting step is performed to cut the string-shaped magnetic gas member 1a wound by the winding machine 70 to a given length.

(8) Locking section fusion bonding step-locking section The fusion bonding step is performed to melt-bond the locking section including the locking portion 22 and the engaging portion 26 to the magnetic gas member 1a cut to a given length Sheath portion 20. In the locking section fusion bonding step, the first opposite end of the sheath portion 20 is attached to the engagement side mold assembly 80 of the pattern 80a including the locking portion 22 as shown in FIG. Then, the separately formed millable type crepe films are inserted into the mold assembly 80. Next, upon application of a given molding pressure to the mold assembly 80, the sheet is melt bonded to the first end of the jacket portion 20. In the same manner, the locking portion 22 is formed at the other end of the sheath portion 20, that is, the second end. The outer shape of the magnetic gas necklace 1 is formed by the locking section fusion bonding step.

(9) Polarization Step In the polarization step, a high magnetic field is applied to the magnet portion 10 covered by the sheath portion 20 to magnetically polarize the magnet portion 10.

By the polarization step, the magnet portion 10 is formed to have magnets of N and S poles each arranged along the longitudinal direction of the magnet portion. In the above manner, the magnetic gas necklace 1 capable of uniformly applying the magnetic flux of the magnet portion 10 to the user's body is formed.

As described above, in the magnetic gas necklace 1 according to the above embodiment, the magnet portion 10 formed of the silicone powder of the mixed magnetic powder is covered by the sheath portion 20 formed of silicone rubber. This makes it possible to prevent the magnetic powder from adhering to the skin of the user or the like and damaging the skin of the user. Further, the magnet portion 10 is formed of a silicone rubber and a magnetic powder mixture, and the sheath portion 20 is formed of the same silicone rubber as the magnet portion 10. This allows the magnet portion 10 and the sheath portion 20 to be in contact with each other with sufficient uniformity so that the magnetic flux emitted from the magnet portion 10 to the outside is easily uniformized, and the blood flow promoting effect of the magnetic flux is effectively exerted on the user's body. Further, since the silicone rubber has a physiologically stable material, it is possible to more easily suppress the adverse effect of the sheath portion on the skin.

In the above embodiment, the powder of the rare earth magnet having high magnetic flux strength is used as the magnetic powder of the magnet portion 10. Thereby, the silicone ratio in the magnet portion 10 can be increased while ensuring the magnetic effect. This allows the magnetic gas necklace 1 to have greater elasticity to more properly contact the skin of the user. If the ratio of silicone is not increased, the magnetic necklace 1 can be reduced in size while ensuring the required elasticity.

In the above embodiment, the locking portion 22 provided to the sheath portion 20 and the engaging portion 26 adapted to be releasably locked by the locking portion 22 are formed of silicone rubber. This allows fusion between the sheath portion 20 and the locking portion 22 and between the engaging portion 26 to facilitate the formation of the locking portion 22 and the engaging portion 26 in the sheath portion 20, and to prevent the locking portion 22 and the engaging portion. 26 is separated from the sheath portion 20.

In the above-described manufacturing method of the magnetic gas necklace 1, the magnet side mixture is extruded in the pressing step while pressing the sheath side mixture to the outer circumference of the magnet side mixture. This makes it possible to easily cover the magnet portion 10 by the sheath portion 20. In the vulcanization step, the extruded magnet side and sheath side mixture are simultaneously vulcanized to effect melting of the tannin in the mixture on the magnet side and the tantalum in the sheath side mixture so that the respective vulcanized mixture will be formed. The integration between the magnet and the sheath portions 10, 20 is facilitated. In particular, in the vulcanization step, the magnet side and the sheath side mixture are each hardened based on vulcanization of the silicone rubber contained in the magnet side and the sheath side mixture. That is, the two extruded mixtures are not vulcanized by vulcanizing the respective mixtures under different conditions. This makes it possible to reduce the complexity of the process and to simplify the manufacturing equipment.

An advantageous embodiment of the invention has been shown and described. It is apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention as set forth in the appended claims. For example, although the above embodiment has been described based on an example in which a mixed powder including a rare earth magnet powder and a ferrite magnet powder is used as the magnetic powder of the magnet portion 10, the magnetic powder used in the present invention is not limited to this. Powder, but may be any suitable magnetic powder, such as neodymium iron-based magnets.

Further, although the mixing ratio of the magnetic powder to the silicone in the above embodiment is set to about 7:3, the present invention is not limited to this specific ratio. In view of the balance between elasticity and magnetic field strength, the mixing ratio of the magnetic powder to the silicone is preferably set in the range of about 5:5 to 9:1.

The diameter of the magnet portion 10 and the thickness of the sheath portion 20 can be appropriately changed.

In addition to the magnetic gas necklace, the present invention can be applied to any other magnetic gas therapy device.

The sheath portion may contain other materials such as a pigment or a colorant as needed.

In the above embodiment, the sheath portion 20 is formed of a single type of mixture. Alternatively, the sheath portion 20 may be formed of a mixture of plural types of different colors. For example, as shown in FIG. 7, the bonding unit in the above embodiment may have a die provided with a plurality of spacers that divide the space between the inner frame 105 and the outer frame 104 into a plurality of subspaces, and The second extruder in the above embodiment may include a plurality of second extruders in which mixtures of different colors are extruded from individual subspaces separated by partitions 104a. In this case, as shown in FIG. 8, a magnetic gas necklace 100 having a sheath portion 20 including a plurality of sub-sheath portions 20a, 20b of different colors may be provided.

As described above, a magnetic gas therapy device is used as a wearable article that includes a chain to exert a blood flow promoting effect on the user's body. The magnetic gas treatment apparatus comprises: an elongated flexible magnet portion formed by a mixture of silicone rubber and magnetic powder to extend in a given direction and magnetically polarized; and a flexible sheath portion formed of silicone rubber Covered on the entire circumference of the magnet section.

In the magnetic gas therapy device, the magnet portion is formed of a silicone rubber and a magnetic powder mixture, and the sheath portion covering the magnet portion is formed of silicone rubber. This allows the magnet portion and the sheath portion to be in contact with each other with sufficient uniformity so that the magnetic flux emitted from the magnet portion to the outside is easily uniformized. That is, in the magnetic gas therapy device, the magnetic flux from the magnet portion is uniformly applied to the body of the user, so that the blood flow promoting effect based on the magnetic flux can be effectively exerted on the user's body. Further, as described above, the sheath portion in the magnetic gas treatment device is formed of silicone having physiological stability. Thereby, even when the magnetic therapeutic apparatus directly contacts the skin of the user, the adverse effect of the sheath portion on the skin can be more surely suppressed.

Preferably, the magnetic gas treatment device is formed by subjecting the silicone and magnetic powder mixture of the magnet portion and the silicone of the sheath portion to a multi-color extrusion molding process.

This feature makes it easier to form the sheath portion in such a manner as to cover the outer circumference of the magnet portion while making the magnet portion and the sheath portion more surely contact each other in the extrusion molding process.

Preferably, in the magnetic gas therapy device, the magnetic powder may be a powder of a rare earth magnet.

According to this feature, a rare earth magnet having a magnetic flux strength higher than that of a conventional magnetic material such as a magnetite portion of a ferrite magnet is used as the magnetic powder. Thereby, even if the amount of magnetic powder in the magnet portion is reduced, the magnetic effect of the required magnet portion can be maintained. This makes it possible to achieve a reduction in the overall size of the appliance while ensuring magnetic effects.

Further, if the amount of magnetic powder is allowed to be reduced while ensuring the same degree of magnetic effect as the manner of explanation, the rubber ratio of the magnet portion can be increased while maintaining the magnetic effect and size of the magnetic therapeutic apparatus to the same extent as the conventional apparatus. This makes it possible to provide a higher restoring force to the magnet portion and achieve greater elasticity of the entire device.

Preferably, the magnetic gas treatment device may include: a locking portion formed by the silicone at an opposite end of the sheath portion; and an engaging portion formed by the silicone at the other end of the sheath portion and adapted to be locked Releasably locked, wherein the magnetic therapy device is adapted to have an annular shape while maintaining the state in which the sheath portion covers the magnet portion when the engaging portion is locked by the locking portion.

This feature allows the magnetic therapy device to have the same increased durability and usability as wearable articles such as necklaces or bracelets. In particular, the locking portion and the engaging portion provided to the sheath portion are formed of silicone rubber so that melting can be performed between the sheath portion and the locking portion and between the engaging portions. This makes it easier to form the locking portion and the engaging portion in the sheath portion, and more reliably prevent the locking portion and the engaging portion from being undesirably separated from the sheath portion, that is, falling off.

Furthermore, the method for manufacturing a magnetic gas therapy apparatus includes: a kneading step of kneading the silicone and magnetic powder of the magnet portion together with the vulcanizing agent in the first kneader, and kneading the rubber of the sheath portion together with the vulcanizing agent in the second kneading. Kneading in the machine; in a feeding step, the kneaded mixture of the tannin extract, the magnetic powder and the vulcanizing agent is fed into the first extruder, and the kneaded rubber and the sheath side mixture of the vulcanizing agent are fed to the second extruder a pressing step of extruding the magnet side mixture from the first extruder while simultaneously pressing the sheath side mixture from the second extruder to the outer circumference of the magnet side mixture; and a vulcanization step of applying heat to The two extruded mixture is used to vulcanize the mixture.

In this method, each of the magnet side mixture and the sheath side mixture can be sufficiently kneaded in the kneading step to prevent a change in the mixed state in the magnet portion and the sheath portion. This makes it possible to achieve uniformization of the magnetic effect of the magnetic powder exerted on the user's body. Further, in this method, the magnet side and the sheath side mixture are respectively filled into the first and second extruders in the feeding step, and in the pressing step, the magnet side mixture is extruded while being extruded The jacket side mixture is to the periphery of the magnet side mixture. This makes it easier to cover the magnet side mixture from the sheath side mixture. Then, in the vulcanization step, the two extruded mixtures are simultaneously vulcanized. This makes it possible to achieve the fusion between the silicone in the mixture on the magnet side and the silicone in the sheath side mixture, so that the integration between the magnet and the sheath portion formed by the respective vulcanized mixture becomes easier. In particular, in a magnetic gas therapy device, the magnet side mixture and the sheath side mixture each may comprise the same type of silicone such that the two extruded mixtures may be vulcanized simultaneously without vulcanizing the mixture under different conditions. This makes it possible to reduce the complexity of the process and to simplify the manufacturing equipment.

The magnetic gas therapy device can uniformly apply magnetic flux to the user's body while more reliably suppressing adverse effects on the user's skin. This method can efficiently manufacture a magnetic gas therapy device in an efficient manner.
