あった。2. Description of the Related Art Generally, an interdental brush is manufactured by folding a wire back in the middle and twisting both ends of the wire by sandwiching a brush between the wires (twisting and bristling). The property of the wire used for this twisted hair is that the brush is fixed by the twisting deformation of the wire, so that the twisting deformation of the wire does not return. That is, as the wire material, one that is plastically deformable is suitable, but one that is elastically deformable is not suitable,
Generally, a bare metal wire such as a stainless soft wire is used. In addition, the interdental brush, from the point of passing of the interdental part,
Although it is required to twist and implant hair using a thin wire as much as possible, the strength of the wire is reduced when the diameter of the wire is reduced, and therefore the wire is easily bent and easily broken, resulting in a problem in durability.

なかった。As means for improving the durability of the wire of an interdental brush, Japanese Utility Model Publication No. 61-180014, Japanese Utility Model Publication No. 63-161536, and Japanese Utility Model Publication No. 3-35730.
There are devices such as Japanese patent publications.In these devices, when positioning the tip of the brush part to the cleaning part, the wire base is bent and used, so that the wire base is repeatedly bent and easily broken. It is an attempt to improve the wire base by coating it with a flexible resin. However, these devices do not improve the strength of the wire itself.Therefore, if the wire diameter is made thinner in order to improve the interdental part of the brush, the strength of the wire is reduced and the coating resin of the wire base is reduced. There is a drawback in that the wire is remarkably deteriorated in durability and is also deteriorated in usability by being deformed at the boundary of the wire or deformed at an intermediate position of the brush portion. Also, as seen in Japanese Utility Model Publication No. 1-41304, an interdental brush in which a wire is coated with a soft elastic resin has been devised, but it prevents the galvanic effect and damages to the tooth, and therefore the wire diameter is If it is thin, it is easily deformed, and it has hardly helped to improve the durability and usability of the wire.

することができなかった。On the other hand, when the wire is hard to bend and has high bending strength (rigidity) in order to improve the durability, the wire is twisted due to the spring back and the brush comes off, which is thin and durable. An interdental brush could not be manufactured.

An interdental brush characterized in that the brush is integrally fixed to the outer circumference of the wire by melting and solidifying the coating resin, and a thermoplastic resin having a melting point lower than the deformation temperature of the brush and a thermal deformation temperature higher than the oral temperature is used.

止される。[Function] By using a wire whose outer periphery is coated with a low-melting thermoplastic resin by a method such as extrusion molding, electrostatic coating, sintering, dipping, etc., after twist-planting, by high-frequency heating, electric heating, heater heating, etc. By heating the brush, melting it, and then solidifying it, an interdental brush in which the outer circumference of the wire and the brush are integrally fixed by the coating resin is obtained. Therefore, even if a high-strength wire is used to improve the durability of the wire, the twisting deformation of the wire is also fixed by the fixing with the coating resin, the spring back does not return, and the brush does not come off. Further, the coating resin on the outer circumference of the wire also prevents the brush from being cut by the wire when the wire is twisted and planted.

Thermoplastic resin having strength and elongation that does not break by deformation during flocking, such as polyethylene (PE), ethylene / vinyl acetate copolymer resin (EVA resin), polypropylene (PP), 6-66 copolymer nylon, 6-66- 12 Copolymer nylon, etc. are suitable. If the coating thickness on the wire is too thick, the wire coating diameter will be thick and the interdental passage will be poor, while if it is too thin, sufficient bonding strength between the wire and the brush will be obtained.

毛を固着する高周波誘電加熱法がある。As a heating method for heating and melting the coating resin, there are high-frequency heating, electric heating, heater heating and the like. However, the coating resin can be uniformly melted and the fixing force of the brush is stabilized, so that the brush can be fixed in a short time. High-frequency heating is preferable because it has the advantages that it can be melted and the brush is not deformed by heating. For high frequency heating, magnetic wires such as ferritic stainless steel, martensitic stainless steel, and precipitation hardening stainless steel are heated by high frequency induction heating to melt the low melting point thermoplastic resin on the outer periphery to remove the wire and brush. There is a high-frequency induction heating method for fixing, and PE, EVA resin, PP, 6-66 copolymer nylon, etc. are suitable as the low melting point thermoplastic resin in this case. In addition, a non-magnetic or weakly magnetic wire such as austenitic stainless steel or cobalt-based alloy is used, and 6-66 copolymer nylon, 6-66-12 copolymer nylon is used as the low melting point thermoplastic resin covering the wire periphery. There is a high-frequency dielectric heating method in which a resin having a high dielectric constant is used to heat and melt the coating resin by high-frequency dielectric heating to fix the wire and the brush.

Then, the wire 1 is heated by a high-frequency induction heating device, and the coating resin 2 is heated and melted, and then cooled and solidified. And the brush 3 were integrally fixed. In this case, the wire 1
The brush 3 is not cut by the coating resin on the outer circumference of the wire, and the twisting deformation of the wire 1 is fixed by the melting and solidification of the coating resin 2 after the production, so that the springback does not occur.
The wire 1 did not fall off during use, and the durability of the interdental brush was improved.
