Description
本発明は、樹脂材料からなる歯間清掃具に関する。 The present invention relates to an interdental cleaning tool made of a resin material.
歯間清掃具として、金属細線からなるワイヤー素線を二つ折りにしてその間にフィラメントを配置させ、このワイヤー素線を捩じってワイヤー素線に対してフィラメントを植毛し、その後フィラメントを所望長さにカットして円柱状や円錐台状に成形してなるブラシ本体とを備えた歯間ブラシが広く実施されている（例えば、特許文献１参照。）。 As an interdental cleaning tool, a wire made of metal wire is folded in two, the filament is placed between them, this wire is twisted, the filament is flocked to the wire, and then the filament is made to a desired length An interdental brush provided with a brush main body formed into a cylindrical shape or a truncated cone shape by being cut into a square shape is widely practiced (see, for example, Patent Document 1).
また、合成樹脂からなる基材部と、エラストマーからなる軟質部とを備え、前記基材部は、ハンドル基材部と、前記ハンドル基材部の先端部に設けた細長い軸状の芯基材部とを有し、前記軟質部は、前記芯基材部を被覆する清掃用軟質部を少なくとも有し、前記ハンドル基材部で持ち手としてのハンドル部を構成し、前記芯基材部と清掃用軟質部とで歯間清掃用の清掃部を構成した歯間清掃具も提案され、実用化されている（例えば、特許文献２参照。）。 In addition, a base portion made of a synthetic resin and a soft portion made of an elastomer are provided, and the base portion is a handle base portion and an elongated shaft-like core base member provided at the tip of the handle base portion. And the soft portion has at least a cleaning soft portion covering the core base portion, and the handle base portion constitutes a handle portion as a handle, and the core base portion The interdental cleaning tool which comprised the cleaning part for interdental cleaning with the soft part for cleaning is also proposed, and is utilized (for example, refer patent document 2).
更に、歯間清掃具として、ナイロン、ポリエステル、ポリプロピレンなどの樹脂繊維からなるデンタルフロスが、広く用いられている。このデンタルフロスは、通常、ボビンに巻装されて収納され、フロスを使用する際には、必要長さをボピンから繰り出して切り取り、フロスの一端部を一方の手で保持し、他端部を他方の手で保持して、フロスの途中部を歯間に挿入し、この状態でフロスを長さ方向に動かして歯垢を除去するように構成されている（例えば、特許文献３参照。）。 Furthermore, dental floss made of resin fibers such as nylon, polyester and polypropylene is widely used as an interdental cleaning tool. This dental floss is usually wound and stored on a bobbin, and when using the floss, the necessary length is drawn out from the bopin and cut off, one end of the floss is held with one hand, the other end is While holding with the other hand, the middle part of the floss is inserted between the teeth, and in this state, the floss is moved in the length direction to remove plaque (see, for example, Patent Document 3). .
一方、結束具として、硫酸バリウムおよび／または炭酸カルシウムからなる無機粒子を含有する熱可塑性樹脂組成物からなる賦形性モノフィラメントを芯材として用い、テープ状の２枚の樹脂フィルム間に該芯材を配置させて、両樹脂フィルムを張り合わせてなる結束具であって、外部応力を作用させて捩じると、該捩じった状態を保持し得る結束具が提案されている（例えば、特許文献４参照。）。 On the other hand, using as a core material a shapeable monofilament made of a thermoplastic resin composition containing inorganic particles consisting of barium sulfate and / or calcium carbonate as a binder, the core material is formed between two tape-shaped resin films And a binder that is made by laminating both resin films, and proposed to be able to hold the twisted state when it is twisted by applying external stress (for example, a patent). Reference 4).
特許文献１記載の歯間ブラシでは、ワイヤー素線を捩じってフィラメントを植設している関係上、製作工程数が多く、製作コストが高いこと、金属ワイヤーの先端部が歯に当たったり、ワイヤーの先端部の折り返し部分が歯間に引っ掛かったりして、不快な思いをすることがあること、金属アレルギーの人は使用できないこと、金属疲労によりワイヤーが折れること、などの問題がある。 In the interdental brush described in Patent Document 1, the wire strands are twisted to implant the filaments, so the number of manufacturing steps is large and the manufacturing cost is high, and the tip of the metal wire hits the teeth. There are problems such as that the folded part of the tip of the wire may get caught between teeth and feel uncomfortable, that a person with metal allergy can not use it, the wire may be broken due to metal fatigue, etc.
一方、特許文献２記載の歯間清掃具では、合成樹脂からなる芯材をエラストマーからなる軟質部で被覆しているので、前述のような歯との接触や引っ掛かりによる不快感を防止でき、金属アレルギーの人でも使用できる。しかし、合成樹脂からなる芯基材部は、金属製ワイヤーと比較して強度剛性が低いことから、大径に構成すると歯間への挿入性が低下し、また反対に歯間への挿入性を考慮して小径に構成すると、比較的容易に折れてしまうこと、芯基材部がワイヤーのように塑性変形しないので、ワイヤーを用いた歯間ブラシと比較して、歯間に対する挿入性が低下すること、清掃部がエラストマーで構成されているので、歯間ブラシと比較して歯間の清掃性が劣ること、などの問題がある。 On the other hand, in the interdental cleaning tool described in Patent Document 2, since the core material made of synthetic resin is covered with the soft portion made of elastomer, the above-mentioned discomfort due to contact with or contact with teeth can be prevented. It can also be used by people with allergies. However, since the core material made of synthetic resin has lower strength and rigidity than metal wires, the large diameter reduces insertability between teeth, and conversely, insertability between teeth. In the case of a small diameter in consideration of the above, it is relatively easy to break, and since the core base portion does not plastically deform like a wire, the insertability between teeth is smaller compared to the interdental brush using a wire. Since the cleaning portion is made of an elastomer, there are problems such as that the cleaning performance between the teeth is inferior to that between the interdental brushes and the like.
また、特許文献３記載のデンタルフロスでは、歯間対向面の清掃性には優れ、効率的に歯垢を除去できるものの、歯間ブラシと比較して歯間部を効率的に清掃できないという問題がある。 Moreover, in the dental floss described in Patent Document 3, although the cleaning property of the interdental surface is excellent and the dental plaque can be efficiently removed, the interdental part can not be cleaned efficiently compared to the interdental brush. There is.
本発明の目的は、歯との接触による不快感の発生を防止できるとともに、歯間の清掃性を十分に確保でき、しかも耐久性に優れるとともに安価に製作可能で、金属アレルギーが発生することもない歯間清掃具を提供するものである。 The object of the present invention is to prevent the occurrence of discomfort due to contact with teeth, to ensure sufficient cleaning between the teeth, to be excellent in durability, to be manufactured at low cost, and to cause metal allergy. Provide an interdental cleaning tool.

先ず、線材製作工程において、異なる樹脂材料を用いて芯材２と羽材３とを同時一体成形して、図４、図５、図６（ａ）に示すような歯間清掃具用線材１を製作する。より具体的には２台の押出機をダイス直前で結合して、芯材２を構成する樹脂材料と、羽材３を構成する樹脂材料とを同時にダイスから押出して、歯間清掃具用線材１を同時一体成形することになる。ただし、予め芯材２を製作し、これをクロスヘッドダイを使用してテープ状の羽材３の中央部に押出して、一体化する製造方法を採用することもできる。 First, in the wire rod manufacturing process, the core material 2 and the feather material 3 are simultaneously integrally molded using different resin materials, and the wire material 1 for interdental cleaning tools as shown in FIG. 4, FIG. 5 and FIG. Produce More specifically, two extruders are connected immediately before the die, and the resin material forming the core material 2 and the resin material forming the feather material 3 are simultaneously extruded from the die, and the wire material for interdental cleaning tools 1 will be integrally molded simultaneously. However, it is also possible to employ a manufacturing method in which the core material 2 is manufactured in advance, and this is extruded to the central portion of the tape-like feather material 3 using a crosshead die and integrated.
次に、持ち手部形成工程において、図６（ｂ）に示すように、プレス加工やレーザー加工などにより、持ち手部１３に対応する位置における羽部３ｂを順次切除して、持ち手部１３を形成するとともに、ブラシ部１２に対応する位置に羽部１２Ａを有する、長さＬ１の複数の単位歯間清掃具１０Ａを連設してなる歯間清掃具２０Ａを製作する。 Next, in the handle formation process, as shown in FIG. 6 (b), the wings 3 b at positions corresponding to the handle 13 are sequentially cut out by press processing, laser processing, etc. Are manufactured, and an interdental cleaning tool 20A having a plurality of unit interdental cleaning tools 10A of length L1 having a wing portion 12A at a position corresponding to the brush portion 12 is manufactured.
次に、ブラシ毛形成工程において、図６（ｃ）、図７に示すように、羽部１２Ａに対してプレス加工やレーザー加工などにより、羽部１２Ａの幅方向に延びる切込み又は切欠きからなる切れ目１５を羽部１２Ａの長さ方向に間隔をあけて複数本形成して、羽部１２Ａを複数本のブラシ毛１２ａに分割したブラシ部１２Ｂを有する、複数の単位歯間清掃具１０Ｂを連設してなる歯間清掃具２０Ｂを製作する。ただし、持ち手部形成工程とブラシ毛形成工程とは同一工程内で行うことも可能であるし、ブラシ毛形成工程を行った後、持ち手部形成工程を行うことも可能である。 Next, in the brush hair forming step, as shown in FIG. 6C and FIG. 7, the wing 12A is formed by notches or notches extending in the width direction of the wing 12A by press working, laser processing, or the like. A plurality of unit interval cleaning tools 10B are formed by forming a plurality of cuts 15 at intervals in the length direction of the wing portion 12A and having brush portions 12B obtained by dividing the wing portion 12A into a plurality of brush bristles 12a. The interdental cleaning tool 20B to be provided is manufactured. However, the handle portion forming step and the brush hair forming step can be performed in the same step, or the brush portion forming step can be performed after the brush hair forming step.
次に、ブラシ部形成工程において、図３に示すように、芯線部１１を中心にしてブラシ部１２Ｂを矢印Ｒの方向へ一定回数だけ捩じった後、歯間清掃具２０Ｂを歯間清掃具１０の長さＬ１にカットして、歯間清掃具１０を得ることになる。ただし、歯間清掃具２０Ｂを歯間清掃具１０の長さＬ１にカットした後、矢印Ｒの方向へ一定回数捩じって、歯間清掃具１０を製作することも可能である。また、歯間清掃具２０Ｂを捩じってから或いは捩じらないで、そのままボビン等に巻装し、利用者に提供することも可能である。更に、線材製作工程において製作した歯間清掃具用線材１を、歯間清掃具１０の長さＬ１にカットした後、持ち手部１３に対応する位置における羽部３ｂを切除し、その後ブラシ毛１２ａを形成し、芯線部１１を中心として捩じることで製作することも可能である。 Next, in the brush portion forming step, as shown in FIG. 3, after twisting the brush portion 12B in the direction of the arrow R a fixed number of times centering on the core wire portion 11, the interdental cleaning tool 20B is cleaned between the teeth By cutting into the length L1 of the tool 10, the interdental cleaning tool 10 is obtained. However, it is also possible to manufacture the interdental cleaning tool 10 by cutting the interdental cleaning tool 20B into the length L1 of the interdental cleaning tool 10 and twisting it in the direction of the arrow R a certain number of times. Also, after the interdental cleaning tool 20B is twisted or untwisted, it can be wound around a bobbin or the like as it is and provided to the user. Furthermore, after cutting the interdental cleaning tool wire 1 manufactured in the wire manufacturing process into the length L1 of the interdental cleaning tool 10, the wing 3b at a position corresponding to the handle 13 is cut off, and then brush bristles It is also possible to form 12a and twist by twisting around the core portion 11.
ブラシ毛形成工程における羽部１２Ａの分割数は、任意に設定可能であるが、５０本／ｃｍ未満の場合には、歯間の清掃性が低下し、２００本／ｃｍを超えると、ブラシ毛１２ａが切れ易くなるので、５０〜２００本／ｃｍに設定することが好ましい。 The division number of the wing 12A in the brush hair forming step can be arbitrarily set, but if it is less than 50 / cm, the cleaning property between the teeth decreases, and if it exceeds 200 / cm, the brush hair It is preferable to set to 50 to 200 pieces / cm because 12a is easily cut.
ブラシ毛１２ａの幅Ｗは、任意に設定可能であるが、０．０５ｍｍ未満の場合には、ブラシ毛１２ａが切れ易くなり、０．２５ｍｍを超えると、歯間の清掃性が低下するので、０．０５ｍｍ〜０．２５ｍｍに設定することが好ましい。ブラシ部１２Ｂは、全て同じ幅Ｗのブラシ毛１２ａで構成してもよいし、異なる幅Ｗのブラシ毛１２ａを混在させて構成してもよい。 The width W of the brush bristles 12a can be arbitrarily set, but if it is less than 0.05 mm, the brush bristles 12a become easy to break, and if it exceeds 0.25 mm, the cleaning property between the teeth decreases, It is preferable to set to 0.05 mm-0.25 mm. The brush portions 12B may be configured by brush hairs 12a having the same width W, or may be configured by mixing brush hairs 12a having different widths W.
切れ目１５は、芯線部１１に対して直交状に形成してもよいし、芯線部１１に対して斜めに角度を付けて形成することもできる。具体的には、図９に示すブラシ部１２ＢＡのように、ブラシ部１２Ｂに代えて、芯線部１１に対して斜めに角度を付けて切れ目１５Ａを形成し、ブラシ部１２ＢＡを複数本のブラシ毛１２ＢＡａに分割構成できる。また、切れ目１５、１５Ａは、直線状に形成したが、サイン波状や三角波状や鋸歯状や矩形波状などの波形状や、円弧状などの曲線状や、直線と曲線の組み合わせ形状に形成することも可能である。 The cut 15 may be formed orthogonal to the core portion 11 or may be formed at an angle with respect to the core portion 11. Specifically, instead of the brush portion 12B as in the brush portion 12BA shown in FIG. 9, the cut 15A is formed at an angle with respect to the core portion 11, and the brush portion 12BA is formed of a plurality of brush hairs. It can be divided into 12 BAa. In addition, although the cuts 15 and 15A are formed in a linear shape, they may be formed in a wave shape such as a sine wave, a triangular wave, a sawtooth shape or a rectangular wave, a curved shape such as an arc shape, or a combination of straight lines and curves. Is also possible.
持ち手部１３は、ブラシ部１２の片側のみに設けることも可能であるが、両側に設けると歯間清掃具１０の操作性を向上できるので好ましい。 Although the handle portion 13 can be provided only on one side of the brush portion 12, providing the handle portion 13 on both sides is preferable because the operability of the interdental cleaning tool 10 can be improved.
持ち手部１３の長さＬ２は、短すぎるとブラシ部１２を操作し難くなり、長すぎると歯間清掃具用線材の使用量が増えて、歯間清掃具１０の材料コストが高くなるので、２５〜５０ｍｍに設定することが好ましい。 If the length L2 of the handle portion 13 is too short, it becomes difficult to operate the brush portion 12. If it is too long, the amount of use of the interdental cleaning tool wire increases and the material cost of the interdental cleaning tool 10 increases. It is preferable to set to 25 to 50 mm.
ブラシ部１２の捩じり回数は、任意に設定可能であるが、１０回／ｃｍを超えると、ブラシ部１２の形状がいびつになって、ブラシ部１２の外観が低下するので、１０回／ｃｍ以下に設定することが好ましい。 The number of times of twisting of the brush portion 12 can be arbitrarily set, but if it exceeds 10 times / cm, the shape of the brush portion 12 becomes distorted and the appearance of the brush portion 12 is deteriorated, so 10 times / It is preferable to set to cm or less.
ブラシ部１２の長さＬ３は、任意に設定可能であるが、短すぎると歯間を清掃し難くなり、長すぎると歯間清掃具用線材の使用量が増えて、歯間清掃具１０の材料コストが高くなるので、５０〜４００ｍｍ、好ましくは１００〜３００ｍｍに設定することが望ましい。 The length L3 of the brush portion 12 can be arbitrarily set, but if it is too short, cleaning between the teeth becomes difficult, and if it is too long, the amount of use of the interdental cleaning tool wire increases. It is desirable to set to 50 to 400 mm, preferably 100 to 300 mm, because the material cost is high.
図９（ｂ）に示すブラシ部１２ＢＢのように、ブラシ部１２Ｂに代えて、外側縁をサイン波状や三角波状や鋸歯状や矩形波状などの波形状に形成し、切れ目１５によりブラシ部１２ＢＢを複数本のブラシ毛１２ＢＢａに分割構成することもできる。 As in the brush portion 12BB shown in FIG. 9B, the outer edge is formed in a sine wave shape, a triangular wave shape, a sawtooth shape, a rectangular wave shape or the like instead of the brush portion 12B. It may be divided into a plurality of brush hairs 12BBa.
また、図８（ａ）に示す歯間清掃具１０Ｃのように、切れ目１５により複数本のブラシ毛１２ａに形成した羽部１２Ａを捩じらない状態で、これをそのまま利用者に提供し、利用者の好みに応じて、ブラシ部１２を捩じって歯間清掃具１０として使用できるように構成したり、図８（ｂ）に示す歯間清掃具１０Ｄのように、切れ目１５を省略するとともに、ブラシ部１２Ａを捩じらないで、これをそのまま利用者に提供し、利用者の好みに応じて、ブラシ部１２Ａを捩じって歯間清掃具１０として使用するように構成したり、図８（ｃ）に示すように、複数の歯間清掃具１０を連設した歯間清掃具２０Ｄをボビン等に巻装し、利用者が１つの歯間清掃具１０をボビンから繰り出して切り取り、使用できるように構成することも可能である。 Further, as shown in FIG. 8 (a), as the interdental cleaning tool 10C does not twist the feather 12A formed on the plurality of brush hairs 12a by the cut 15, this is provided to the user as it is, According to the preference of the user, the brush portion 12 can be twisted to be used as the interdental cleaning tool 10, or the cut 15 can be omitted as in the interdental cleaning tool 10D shown in FIG. 8 (b). And the brush portion 12A is provided to the user as it is without twisting, and the brush portion 12A is configured to be used as the interdental cleaning tool 10 according to the preference of the user. As shown in FIG. 8C, the inter-tooth cleaning tool 20D in which a plurality of inter-tooth cleaning tools 10 are connected is wound around a bobbin or the like, and the user draws out one inter-tooth cleaning tool 10 from the bobbin It is also possible to cut it out and configure it for use.
また、羽部１２Ａをブラシ毛１２ａに分割しないで、これをそのまま芯線部１１を中心にして螺旋状に捩じり、この螺旋状に捩じった羽部でブラシ部１２を構成することも可能である。また、歯間清掃具用線材１を螺旋状に捩じらないで、平板状の羽部１２Ａで歯間を清掃するように構成することも可能である。螺旋状に捩じらない場合には、塑性変形しない素材で歯間清掃具用線材１を製作することも可能である。 In addition, it is also possible not to divide the wing portion 12A into the brush hairs 12a, and to twist it in a spiral shape centering on the core wire portion 11 as it is, and to form the brush portion 12 with this spirally twisted wing portion. It is possible. Moreover, it is also possible to comprise so that between teeth may be cleaned with flat blade part 12A, without twisting the wire 1 for interdental cleaning tools helically. If the helical wire is not twisted, it is also possible to manufacture the interdental cleaning tool wire 1 from a material that does not deform plastically.
次に、歯間清掃具用線材１について説明する。
図３、図４に示すように、歯間清掃具用線材１は、樹脂材料で構成した中実の芯材２と、芯材２を構成する樹脂材料とは異なる樹脂材料で構成した羽材３とからなり、羽材３が、芯材２に外装される鞘部３ａと、鞘部３ａから芯材２の長さ方向と直交する方向の外方側へ延びる少なくとも１枚の羽部３ｂを有し、芯材２と羽材３とを同時一体成形したものである。
Next, the interdental cleaning tool wire 1 will be described.
As shown in FIGS. 3 and 4, the interdental cleaning tool wire 1 is made of a solid core material 2 made of a resin material and a feather material made of a resin material different from the resin material constituting the core material 2. 3 and the sheath 3 is covered with the core 2, and at least one wing 3b extending outward from the sheath 3a in a direction perpendicular to the longitudinal direction of the core 2. And the core 2 and the feather 3 are integrally molded at the same time.
芯材２を構成する樹脂材料としては、ポリエチレンテレフタレート（以下、ＰＥＴという）、ポリブチレンテレフタレート（以下、ＰＢＴという）、ポリエチレンナフタレート、ポリシクロヘキサンジメチレンテレフタレート等のポリエステル樹脂およびその共重合体、ナイロン６、ナイロン６６、ナイロン６１０、ナイロン６１２、ナイロン６／６６共重合体等のポリアミド樹脂およびその共重合体、ポリフッ化ビニリデン、エチレン・テトラフルオロエチレン共重合体、テトラフルオロエチレン・ヘキサフルオロプロピレン・フッ化ビニリデン共重合体等のフッ素樹脂、ポリエチレン、ポリプロピレン等のポリオレフィン樹脂、ポリフェニレンスルフィド樹脂（以下、ＰＰＳという）、ポリエーテルエーテルケトン樹脂（ＰＥＥＫ）、ポリアセタール樹脂、等の熱可塑性樹脂を好適に採用できるが、強度や靭性、口腔内での使用安全性の面から、ポリエステル、ポリアミド、ＰＰＳ、ＰＥＥＫから選ばれた少なくとも１つの樹脂材料を採用することが好ましい。 Examples of resin materials constituting the core material 2 include polyester resins such as polyethylene terephthalate (hereinafter referred to as PET), polybutylene terephthalate (hereinafter referred to as PBT), polyethylene naphthalate, polycyclohexane dimethylene terephthalate and copolymers thereof, nylon 6, Polyamide resins such as nylon 66, nylon 610, nylon 612, nylon 6/66 copolymer and copolymers thereof, polyvinylidene fluoride, ethylene / tetrafluoroethylene copolymer, tetrafluoroethylene, hexafluoropropylene, fluorine Fluorocarbon resins such as vinylidene fluoride copolymer, polyolefin resins such as polyethylene and polypropylene, polyphenylene sulfide resin (hereinafter referred to as PPS), polyetheretherketone resin (PEEK) Although thermoplastic resins such as acetal resins can be suitably employed, at least one resin material selected from polyester, polyamide, PPS, and PEEK in view of strength, toughness, and safety in use in the oral cavity. Is preferred.
羽材３を構成する樹脂材料としては、歯間清掃性を考慮して、スチレン系、オレフィン系、ポリアミド系等の熱可塑性エラストマーや、ＰＥＴ、ＰＢＴ、ポリエチレンナフタレート、ポリシクロヘキサンジメチレンテレフタレート等のポリエステル樹脂およびその共重合体、ナイロン６、ナイロン６６、ナイロン６１０、ナイロン６１２、ナイロン６／６６共重合体等のポリアミド樹脂およびその共重合体から選ばれた少なくとも１つの樹脂材料を採用することが好ましい。 As a resin material which constitutes feather material 3, thermoplastic elastomers, such as a styrene system, an olefin system, and a polyamide system, PET, PBT, polyethylene naphthalate, polycyclohexane dimethylene terephthalate etc. are considered in consideration of the cleaning property between teeth. Employing at least one resin material selected from polyamide resins such as polyester resins and copolymers thereof, nylon 6, nylon 66, nylon 610, nylon 612, nylon 6/66 copolymers and copolymers thereof preferable.
芯材２の樹脂材料には無機粒子が含有され、歯間清掃具用線材１が塑性変形できるように構成されている。この無機粒子の材質としては、ガラスビーズ、タルク、シリカ、マイカ、炭酸カルシウム、水酸化マグネシウム、アルミナ、酸化亜鉛、酸化マグネシウム、水酸化マグネシウム、シリカアルミナ、酸化チタン、酸化カルシウム、ケイ酸カルシウム、硫化モリブデン、酸化アンチモン、クレー、珪藻土、硫酸カルシウム、亜硫酸カルシウム、リン酸カルシウム、酸化鉄、硫酸バリウム、炭酸マグネシウム、塩基性炭酸マグネシウム、ドロマイド、モンモリロナイト、ベントナイト、鉄粉、鉛粉、亜鉛粉、アルミニウム粉、カーボンブラック等が例示できる。これらの中でも、熱可塑性樹脂中への分散性や価格の面から、特に硫酸バリウム、炭酸カルシウム、リン酸カルシウムから選ばれた少なくとも１種を採用することが好ましい。 Inorganic particles are contained in the resin material of the core material 2 so that the interdental cleaning tool wire 1 can be plastically deformed. Materials of the inorganic particles include glass beads, talc, silica, mica, calcium carbonate, magnesium hydroxide, alumina, zinc oxide, magnesium oxide, magnesium hydroxide, silica alumina, titanium oxide, calcium oxide, calcium silicate, sulfide Molybdenum, antimony oxide, clay, diatomaceous earth, calcium sulfate, calcium sulfite, calcium phosphate, iron oxide, barium sulfate, magnesium carbonate, basic magnesium carbonate, dromid, montmorillonite, bentonite, iron powder, lead powder, zinc powder, aluminum powder, carbon Black etc. can be illustrated. Among these, it is preferable to use at least one selected from among barium sulfate, calcium carbonate and calcium phosphate, from the viewpoint of dispersibility in the thermoplastic resin and cost.
このように、芯材２を構成する樹脂材料に無機粒子を配合すると、芯材２の弾性回復性を抑制し、芯材２が塑性変形可能に構成されて、例えば歯間清掃具用線材１を捩じると、その捩じった形状が芯材２の塑性変形により維持されるという、優れた賦形性が得られる。無機粒子を含有することによる賦形性の向上の機構は明確ではないが、樹脂材料中に分散された無機粒子が、樹脂ポリマー鎖間の相互作用を部分的に阻害するため、芯材２の変形時にミクロな空隙を作り出し、さらにこのミクロな空隙が歪んだり、裂けたりといった不可逆的な変形をするため、優れた賦形性を有するものと推定される。また、芯材２としては、賦形性をより一層向上するため、延伸することが好ましい。 Thus, when inorganic particles are blended in the resin material which constitutes core material 2, elastic recovery of core material 2 is controlled and core material 2 is constituted so that plastic deformation is possible, for example, wire rod 1 for cleaning teeth between teeth By twisting, excellent formability is obtained, in which the twisted shape is maintained by plastic deformation of the core material 2. Although the mechanism of the improvement of the formability by containing the inorganic particles is not clear, the inorganic particles dispersed in the resin material partially inhibit the interaction between the resin and polymer chains. It is presumed to have excellent shapeability because it produces micro voids upon deformation and causes irreversible deformation such as distortion or tearing of the micro voids. Moreover, as the core material 2, in order to further improve the shaping property, it is preferable to stretch.
次に、歯間清掃具用線材１の具体的な形状について図面を参照しながら説明する。
図３、図４に示すように、歯間清掃具用線材１は、樹脂材料で構成した中実の芯材２と、芯材２を構成する樹脂材料とは異なる樹脂材料で構成した羽材３であって、芯材２に外装される鞘部３ａと、鞘部３ａから芯材２の長さ方向と直交する方向の外方側へ延びる少なくとも１枚の羽部３ｂを有する羽材３とを備え、芯材２と羽材３とが同時一体成形され、芯材２の長さ方向と直交する断面方向における、芯材２の最大幅αと、羽部３ｂの先端部から芯材２の中心Ｐまでの最大距離βとの比率α／２βを０．０２５〜０．７５に設定したものである。
Next, the specific shape of the interdental cleaning tool wire 1 will be described with reference to the drawings.
As shown in FIGS. 3 and 4, the interdental cleaning tool wire 1 is made of a solid core material 2 made of a resin material and a feather material made of a resin material different from the resin material constituting the core material 2. A wing 3 having a sheath 3a which is encased in the core 2, and at least one wing 3b extending outward from the sheath 3a in a direction perpendicular to the length direction of the core 2; And the core material 2 and the wing material 3 are simultaneously integrally molded, and the core material 2 from the tip end of the wing portion 3b in the cross-sectional direction orthogonal to the length direction of the core material 2 and the core material The ratio α / 2β to the maximum distance β to the center P of 2 is set to 0.025 to 0.75.
芯材２は、それを構成する樹脂材料に対して、前述のように無機粒子を添加して、塑性変形可能に構成することが好ましい。このように構成することで、歯間清掃具用線材１を捩じると、その捩じった形状が芯材２の塑性変形により維持されるので、例えば図３、図４に示す歯間清掃具用線材１のように、芯材２を中心として歯間清掃具用線材１を捩じることによって、歯間清掃具用線材１の芯材２と羽材３と鞘部３ａと羽部３ｂを捩じってなる、芯材２と羽材３と鞘部３ａと羽部３ｂをそれぞれ形成し、螺旋状に形成される羽部３ｂを歯間清掃具１０の清掃部として用いることで、羽部３ｂにより掻き出し効果を高めて、歯間の清掃性を一層向上することができる。また、歯間への挿入方向を考慮して、歯間清掃具用線材１を折り曲げて、臼歯部間への挿入性を向上することもできる。 The core material 2 is preferably configured so as to be plastically deformable by adding inorganic particles as described above to the resin material that constitutes it. With such a configuration, when the interdental cleaning tool wire 1 is twisted, the twisted shape is maintained by the plastic deformation of the core member 2. Therefore, for example, between the teeth shown in FIGS. 3 and 4 As in the case of the cleaning tool wire 1, by twisting the interdental cleaning tool wire 1 with the core 2 as the center, the core material 2, the feather 3, the sheath 3 a and the feather of the interdental cleaning tool wire 1 Forming the core 2, the wing 3, the sheath 3 a and the wing 3 b by twisting the part 3 b and using the wing 3 b formed in a spiral shape as the cleaning part of the interdental cleaning tool 10 Thus, the scraping effect can be enhanced by the wing portion 3b, and the cleaning performance between the teeth can be further improved. Moreover, in consideration of the insertion direction between teeth, the interdental cleaning tool wire 1 can be bent to improve the insertability between the molars.
芯材２の長さ方向と直交する断面の形状（横断面形状）は、図３に示す芯材２のように円形に形成することができる。ただし、芯材２の長さ方向と直交する断面の形状は、任意の形状に形成することが可能で、例えば２個以上の円若しくは偏平円が部分的に重なった形状、楕円形、多角形又は不定形に形成すると、歯間清掃具用線材１を捩じっても、芯材２と羽材３とが物理的、機械的に係合して、両者の相対回転を防止できるので、歯間清掃具用線材１を捩じった状態に形状維持する上で好ましい。具体的には、図１０（ａ）に示す歯間清掃具用線材１Ａのように、芯材２Ａの横断面形状を、２個の円が部分的に重なったマユ型形状に形成し、それに応じた形状に鞘部３Ａａを形成したり、図１０（ｂ）に示す歯間清掃具用線材１Ｂのように、芯材２Ｂの横断面形状を、３個の円が部分的に重なった三つ葉形状に形成したり、図１０（ｃ）に示す歯間清掃具用線材１Ｃのように、芯材２Ｃの横断面形状を長方形状に形成し、それに応じた形状に鞘部３Ｃａを形成したりすることができる。 The shape (cross-sectional shape) of the cross section orthogonal to the length direction of the core material 2 can be formed circularly like the core material 2 shown in FIG. However, the shape of the cross section orthogonal to the length direction of the core material 2 can be formed into any shape, for example, a shape in which two or more circles or flat circles partially overlap, an oval, or a polygon Alternatively, if the interdental cleaning tool wire 1 is twisted, the core 2 and the feather 3 can be physically and mechanically engaged to prevent relative rotation between the two, even if the interdental cleaning tool wire 1 is twisted. It is preferable to maintain the shape of the interdental cleaning tool wire 1 in a twisted state. Specifically, as shown in FIG. 10 (a), the cross-sectional shape of the core 2A is formed into a mule shape in which two circles partially overlap, as in the wire 1A for an interdental cleaning tool shown in FIG. As shown in FIG. 10 (b), a sheath 3Aa is formed in a shape according to the shape according to the cross-sectional shape of the core 2B as in the interdental cleaning tool wire 1B, three-leaf in which three circles partially overlap As shown in FIG. 10 (c), the core 2C is formed in a rectangular cross-sectional shape, and the sheath 3Ca is formed in a corresponding shape, as shown in FIG. 10 (c). can do.
芯材２の最大幅αは、任意に設定可能であるが、０．２〜１．５ｍｍ、望ましくは０．４〜１．０ｍｍに設定することが好ましい。つまり、芯材２の最大幅αが０．２ｍｍ未満の場合には、塑性変形時における歯間清掃具用線材１の形状安定性を十分に確保することが困難になるとともに、歯間清掃具用線材１の耐久性を十分に確保できず、１．５ｍｍを超えると、歯間清掃具用線材１の鞘部３ａの外形が大きくなって、歯間への挿入性が低下するので、０．２〜１．５ｍｍに設定することが好ましい。 The maximum width α of the core material 2 can be arbitrarily set, but is preferably set to 0.2 to 1.5 mm, preferably 0.4 to 1.0 mm. That is, when the maximum width α of the core member 2 is less than 0.2 mm, it becomes difficult to sufficiently ensure the shape stability of the interdental cleaning tool wire 1 during plastic deformation, and the interdental cleaning tool The durability of the wire rod 1 can not be sufficiently secured, and if it exceeds 1.5 mm, the outer shape of the sheath portion 3a of the wire rod 1 for interdental cleaning tools becomes large, and the insertability between teeth decreases. It is preferable to set to .2-1.5 mm.
羽部３ｂは、その厚さ方向の中心を含む面内に芯材２の中心線が配置されるように形成されている。ただし、羽部３ｂの厚さ方向の中心を含む面が芯材２の中心線からオフセットした位置に配置されるように、羽部３ｂを形成することもできる。 The wing portion 3 b is formed such that the center line of the core 2 is disposed in a plane including the center in the thickness direction. However, the wings 3 b can be formed so that the plane including the center in the thickness direction of the wings 3 b is disposed at a position offset from the center line of the core 2.
羽部３ｂの厚さＴは、任意に設定可能であるが、厚すぎると歯間清掃時の使用感が低下し、薄すぎると成形性が低下するとともに、歯間清掃時に羽部３ｂが破損し易くなるので、０．０５〜０．２０ｍｍ、望ましくは０．０５〜０．１２５ｍｍに設定することが好ましい。 The thickness T of the wing portion 3b can be set arbitrarily, but when it is too thick, the feeling of use during interdental cleaning decreases, while when it is too thin, the formability decreases and the feather 3b breaks during interdental cleaning Since it becomes easy to do, it is preferable to set it as 0.05-0.20 mm, desirably 0.05-0.125 mm.
羽部３ｂの枚数は、図３、図４に示す歯間清掃具用線材１の羽材３では２枚に設定したが、１枚でもよいし、３枚以上に設定することも可能である。例えば、図１１（ａ）に示す歯間清掃具用線材１Ｄの羽材３Ｄのように１枚でもよいし、図１１（ｂ）に示す歯間清掃具用線材１Ｅの羽材３Ｅのように４枚設けることもできる。羽部３ｂを複数枚設ける場合には、隣接する羽部３ｂのなす角度は同じに設定することもできるし、異なる角度に設定することもできる。 The number of feathers 3b is set to two for the feathers 3 of the interdental cleaning tool wire 1 shown in FIGS. 3 and 4, but may be one or three or more. . For example, it may be a single sheet like the feather 3D of the interdental cleaning tool wire 1D shown in FIG. 11 (a), or may be one like the feather 3E of the interdental cleaning tool wire 1E shown in FIG. Four sheets can also be provided. When a plurality of wing portions 3b are provided, the angles formed by the adjacent wing portions 3b can be set to be the same or can be set to different angles.
芯材２の長さ方向と直交する断面方向における、羽部３ｂの最大長さγは、任意に設定可能であるが、０．７５ｍｍ未満の場合には、歯間の清掃性を十分に確保できず、３．８５ｍｍを超えると、歯間清掃具用線材１の歯間への挿入性が低下するので、０．７５〜３．８５ｍｍ、望ましくは１．０〜３．０ｍｍに設定することが好ましい。 The maximum length γ of the wing 3b in the cross-sectional direction orthogonal to the length direction of the core member 2 can be set arbitrarily, but if less than 0.75 mm, sufficient inter-teeth cleaning is ensured If it exceeds 3.85 mm, the insertability of the interdental cleaning tool wire 1 to the inter teeth decreases, so set it to 0.75 to 3.85 mm, preferably 1.0 to 3.0 mm. Is preferred.
羽部３ｂの先端部から芯材２の中心Ｐまでの最大距離βは、１．０〜５．０ｍｍ、望ましくは１．３〜４．０ｍｍに設定することが好ましい。最大距離βは、歯間サイズに応じて適宜に設定できるが、最大距離βを１．０〜５．０ｍｍに設定すると、歯間に対する歯間清掃具用線材１の挿入性を十分に確保できるとともに、歯間の清掃性を十分に確保できる。 The maximum distance β from the tip of the wing 3b to the center P of the core 2 is preferably set to 1.0 to 5.0 mm, preferably 1.3 to 4.0 mm. The maximum distance β can be appropriately set according to the interdental size, but if the maximum distance β is set to 1.0 to 5.0 mm, the insertability of the interdental cleaning tool wire 1 to the interdental teeth can be sufficiently ensured. At the same time, it is possible to ensure sufficient cleaning between the teeth.
羽部３ｂの先端部（外側縁）は、図１２（ａ）に示す歯間清掃具用線材１Ｆの羽材３Ｆの羽部３Ｆｂのように、先細りの先細部４で構成することもできるし、図１２（ｂ）に示す歯間清掃具用線材１Ｇの羽材３Ｇの羽部３Ｇｂのように、先端側へ行くにしたがって厚肉になる厚肉部５で構成することもできるし、図１２（ｃ）に示す歯間清掃具用線材１Ｈの羽材３Ｈの羽部３Ｈｂのように、横断面円形の柱状部で構成することもできる。歯間清掃具用線材１Ｆのように先細部４を形成すると、歯間への挿入性を向上でき、歯間清掃具用線材１Ｇ、１Ｈのように厚肉部５や柱状部６を形成すると、掻き出し効果をたかめて、歯間の清掃性を向上できる。 The tip (outer edge) of the wing portion 3b can also be configured with a tapered portion 4 like the wing portion 3Fb of the wing material 3F of the interdental cleaning tool wire 1F shown in FIG. 12 (a) As shown in FIG. 12 (b), like a wing 3Gb of a feather 3G of a wire 1G for an interdental cleaning tool, it can be constituted by a thick portion 5 which becomes thicker as it goes to the tip side. Like a wing portion 3Hb of a feather 3H of a wire 1H for an interdental cleaning tool shown in FIG. 12 (c), it can also be constituted by a columnar portion having a circular cross section. If the tapered portion 4 is formed as in the interdental cleaning tool wire 1F, the insertability between the teeth can be improved, and if the thick portion 5 or the columnar portion 6 is formed as in the interdental cleaning tool wire 1G, 1H The cleaning effect between teeth can be improved by using a scraping effect.
芯材２の長さ方向と直交する断面方向における、鞘部３ａの最大幅δは０．３〜２．０ｍｍに、望ましくは０．５〜１．４ｍｍに設定することが好ましい実施の形態である。このように構成すると、鞘部３ａの剥離を防止しつつ、歯間清掃具用線材１の歯間への挿入性を十分に確保できる。 In a preferred embodiment, the maximum width δ of the sheath portion 3a in the cross-sectional direction orthogonal to the longitudinal direction of the core member 2 is set to 0.3 to 2.0 mm, preferably 0.5 to 1.4 mm. is there. According to this structure, it is possible to sufficiently ensure the insertability between the teeth of the interdental cleaning tool wire 1 while preventing peeling of the sheath portion 3a.
単位長さ当たりにおける、芯材２の重量Ｗ１と、羽材３の重量Ｗ２との重量比率Ｗ１／Ｗ２を２０／８０〜６０／４０に設定することが好ましい。つまり、重量比率Ｗ１／Ｗ２は、２０／８０未満の場合には、賦形性が低下し且つ強度が低くて歯間に挿入し難くなり、６０／４０を超えると、太くなり過ぎて歯間に挿入し難くなるとともに、捩じり難くなるので、２０／８０〜６０／４０、望ましくは２５／７５〜４０／６０に設定することが好ましい。 It is preferable to set weight ratio W1 / W2 of weight W1 of core material 2 to weight W2 of feather 3 per unit length to 20/80 to 60/40. In other words, if the weight ratio W1 / W2 is less than 20/80, the formability is reduced and the strength is low and it becomes difficult to insert between the teeth, and if it exceeds 60/40, it becomes too thick and the interdental space It is preferable to set it to 20/80 to 60/40, preferably 25/75 to 40/60, since it becomes difficult to insert the screw and to twist.
この歯間清掃具１０では、樹脂材料で構成した中実の芯材と、該芯材を構成する樹脂材料とは異なる樹脂材料で構成した羽材とからなる歯間清掃具用線材１を用いて歯間清掃具１０を構成し、ワイヤー素線を用いないので、ブラシ部１２と歯との接触による不快感の発生を防止できるとともに、樹脂材料を適正に選定することで耐久性を向上でき、しかも金属アレルギーの人でも使用できる歯間清掃具１０を実現できる。また、羽材３に、芯材２の長さ方向と直交する方向の外方側へ延びる羽部３ｂを形成し、この羽部３ｂに切れ目１５を入れて形成したブラシ部１２により歯間を清掃できるので、歯間ブラシと同等の清掃性を確保することが可能となる。更に、芯材２と羽材３とを同時一体成形して歯間清掃具用線材１を製作できるので、歯間ブラシと比較してブラシ部１２の製作コストを安くできる。 In this interdental cleaning tool 10, the interdental cleaning tool wire 1 comprising a solid core material made of a resin material and a feather material made of a resin material different from the resin material constituting the core material is used. Since the interdental cleaning tool 10 is configured and no wire wire is used, generation of discomfort due to contact between the brush portion 12 and the teeth can be prevented, and durability can be improved by appropriately selecting the resin material. In addition, it is possible to realize the interdental cleaning tool 10 that can be used even by people with metal allergy. Further, a feather portion 3b extending outward in a direction orthogonal to the length direction of the core material 2 is formed on the feather material 3, and a brush section 12 is formed by inserting a cut 15 in the feather portion 3b. Since cleaning is possible, it is possible to ensure the same cleaning performance as the interdental brush. Furthermore, since the core material 2 and the feather material 3 can be simultaneously integrally molded to produce the interdental cleaning tool wire 1, the manufacturing cost of the brush portion 12 can be reduced compared to the interdental brush.
次に、ブラシ部１２の評価試験について説明する。
図３、図４に示すように、ブラシ部１２を構成する歯間清掃具用線材１として、ポリエチレンテレフタレートに対して硫酸バリウムからなる無機粒子を含有させてなる芯材２と、２枚の羽部３ｂを有するポリエステル系エラストマ（ハイトレル：東レ・デュポン社株式会社製）からなる羽材３とを一体成形してなり、芯材２の最大幅αが０.５ｍｍ、羽部３ｂの先端部から芯材２の中心Ｐまでの最大距離βが２．９ｍｍ、羽部３ｂの厚さが０．１３ｍｍ、羽部３ｂの最大長さγが２．５ｍｍの歯間清掃具用線材１を製作した。そして、図６（ｂ）に示すように長方形状に形成した羽部１２Ａに、図７に示すように、０．１０ｍｍ、０．１５ｍｍ、０．２０ｍｍのピッチで長さ方向に間隔をあけてプレス加工やレーザー加工にて切れ目１５を入れて、幅Ｗが０．１０ｍｍ、０．１５ｍｍ、０．２０ｍｍのブラシ毛１２ａを形成した３種類のブラシ部１２を製作した。
Next, an evaluation test of the brush unit 12 will be described.
As shown in FIG. 3 and FIG. 4, as the interdental cleaning tool wire 1 constituting the brush unit 12, a core material 2 made of polyethylene terephthalate containing inorganic particles of barium sulfate, and two feathers Integrally formed with a polyester-based elastomer (Hytrel, manufactured by Toray DuPont Co., Ltd.) having a portion 3b, and the core 2 has a maximum width α of 0.5 mm and the tip of the wing 3b The interdental cleaning wire 1 was manufactured with a maximum distance β of the core 2 to the center P of 2.9 mm, a thickness of the wing 3 b of 0.13 mm, and a maximum length γ of the wing 3 b of 2.5 mm. . Then, as shown in FIG. 7, the wing portion 12A formed in a rectangular shape as shown in FIG. 6B is spaced in the length direction at a pitch of 0.10 mm, 0.15 mm, 0.20 mm. By making cuts 15 by press processing or laser processing, three types of brush portions 12 having brush bristles 12a having widths W of 0.10 mm, 0.15 mm, and 0.20 mm were produced.
こうして製作したブラシ部１２のうちの、ブラシ毛１２ａの幅Ｗが０．１０ｍｍ、０．１５ｍｍのブラシ部に関しては、芯線部１１を中心とした１ｃｍ当たりの捩じり回数が、３回、５回、７回、１０回となるように捩じり、その後手を放した後における、円柱状のブラシ部１２の状態を写真撮影した。また、ブラシ毛１２ａの幅Ｗが０．２０ｍｍのブラシ部１２に関しては、芯線部１１を中心とした１ｃｍ当たりの捩じり回数が、３回、７回となるように捩じり、その後手を放した後における円柱状のブラシ部１２の状態を写真撮影した。その結果を表１に示す。 Among the brush parts 12 produced in this manner, the number of twists per 1 cm centering on the core part 11 is 3, 5 for the brush parts having a width W of 0.10 mm and 0.15 mm of the brush hairs 12a. The state of the cylindrical brush portion 12 was photographed after twisting 7 times and 10 times and releasing the hand thereafter. In addition, with respect to the brush portion 12 having a width W of 0.20 mm of the brush hair 12a, the number of twists per 1 cm centering on the core wire portion 11 is 3 times and 7 times, and then hand The state of the cylindrical brush portion 12 after releasing The results are shown in Table 1.
また、ブラシ毛１２ａの幅Ｗ及び捩じり回数の異なる前記１０種類のブラシ部１２について、サンスター株式会社製のガム・ソフトピックを用いた場合の清掃面積を１００とした場合における、清掃面積をそれぞれ求めた。その結果を図１３に示す。清掃面積は、Ａｄｏｂｅ Ｐｈｏｔｏｓｈｏｐ（アドビシステムズ社製）を使用し、清掃前後の画像解析によって測定した。 In addition, the cleaning area when the cleaning area when using a soft soft pick made by Sun Star Co., Ltd. is 100 for the 10 types of brush parts 12 having different widths W of the bristles 12 a and the number of times of twisting. I asked for each. The results are shown in FIG. The cleaning area was measured by image analysis before and after cleaning using Adobe Photoshop (manufactured by Adobe Systems).
表１に示すように、捩じり回数は、３回〜７回の範囲では、ブラシ毛１２ａは綺麗な螺旋形状となるが、１０回を超えると、ブラシ毛１２ａの螺旋形状が乱れることが分かる。 As shown in Table 1, while the number of times of twisting is in the range of 3 times to 7 times, the brush hair 12a becomes a beautiful helical shape, but when it exceeds 10 times, the helical shape of the brush hair 12a may be disturbed I understand.
また、図１３に示すように、清掃性に関しては、捩じり回数が１０回を超えても、サンスター株式会社製のガム・ソフトピックと比較して２．５倍以上の清掃性が得られ、ブラシ毛１２ａの幅Ｗが０．１０ｍｍ、０．１５ｍｍでは、捩じり回数が３回〜７回において良好な清掃性が得られることが分かる。 Further, as shown in FIG. 13, regarding the cleaning property, even if the number of times of twisting exceeds 10 times, the cleaning property of 2.5 times or more is obtained as compared with the Gum soft pick made by Sun Star Co., Ltd. It can be seen that when the width W of the brush bristles 12a is 0.10 mm and 0.15 mm, good cleaning performance can be obtained when the number of times of twisting is 3 to 7 times.
次に、歯間清掃具の持ち手部が歯間に挿入可能な強度を有するか否かを評価した。
図５に示す歯間清掃具用線材１の芯線部１１として、芯材２をポリエステルに硫酸バリウムを添加した樹脂製で構成し、羽材３をポリエステルエラストマーで構成し、２枚の羽部３ｂを除去したものを用いた。実施例１では、芯材２の直径を０．７０ｍｍに設定し、鞘部３ａの厚みを０．０９ｍｍに設定し、ポリエステルエラストマーとしてショアＤ硬度７２のものを用いた。実施例２では、芯材２の直径を０．６８ｍｍに設定し、鞘部３ａの厚みを０．０９ｍｍに設定し、ポリエステルエラストマーとしてショアＤ硬度７２のものを用いた。実施例３では、芯材２の直径を０．７５ｍｍに設定し、鞘部３ａの厚みを０．０５ｍｍに設定し、ポリエステルエラストマーとしてショアＤ硬度６３のものを用いた。実施例４では、芯材２の直径を０．６８ｍｍに設定し、鞘部３ａの厚みを０．０５ｍｍに設定し、ポリエステルエラストマーとしてショアＤ硬度６３のものを用いた。また、比較例１〜３として、サンスター株式会社製のバトラーフロスレッダー、サンスター株式会社製のバトラーイージースレッドフロス、Ｐ＆Ｇ社製のoral-Bスーパーフロスをそれぞれ用いた。
Next, it was evaluated whether the handle part of the interdental cleaning tool had the strength which can be inserted between teeth.
As core wire portion 11 of interdental cleaning tool wire 1 shown in FIG. 5, core material 2 is made of polyester plus barium sulfate resin, feather material 3 is made of polyester elastomer, and two feathers 3b The one from which the was removed was used. In Example 1, the diameter of the core material 2 was set to 0.70 mm, the thickness of the sheath portion 3a was set to 0.09 mm, and a material having a Shore D hardness of 72 was used as the polyester elastomer. In Example 2, the diameter of the core material 2 was set to 0.68 mm, the thickness of the sheath portion 3a was set to 0.09 mm, and a material having a Shore D hardness of 72 was used as the polyester elastomer. In Example 3, the diameter of the core material 2 was set to 0.75 mm, the thickness of the sheath portion 3 a was set to 0.05 mm, and a material having a Shore D hardness of 63 was used as the polyester elastomer. In Example 4, the diameter of the core material 2 was set to 0.68 mm, the thickness of the sheath portion 3a was set to 0.05 mm, and a material having a Shore D hardness of 63 was used as the polyester elastomer. In addition, as Comparative Examples 1 to 3, butler flosser manufactured by Sun Star Co., Ltd., butler easy thread floss manufactured by Sun Star Co., Ltd. and oral-B super floss manufactured by P & G Co., Ltd. were used respectively.
そして、株式会社島津製作所製のオートグラフＡＧＳに、冶具から１０ｍｍ突出するように、実施例１〜４、比較例１〜３の芯線部を順次セットして、１０ｍｍ／ｍｉｎの速度で、芯線部の長さ方向に圧縮荷重を加え、その最大値する測定する試験を３回行った。表２に、各測定結果とその平均値を示す。 Then, the core portions of Examples 1 to 4 and Comparative Examples 1 to 3 are sequentially set so as to protrude 10 mm from the jig on an autograph AGS manufactured by Shimadzu Corporation, and the core portion at a speed of 10 mm / min. A compressive load was applied in the longitudinal direction, and the test for measuring its maximum value was performed three times. Table 2 shows each measurement result and its average value.
表２から、実施例１〜４の芯線部（持ち手部）では、比較例１〜３の４〜１０倍程度の耐圧縮性が得られ、歯間に対して無理なく挿入できることが分かる。 From Table 2, in the core wire part (handhold part) of Examples 1-4, about 4-10 times of compression resistance of Comparative Examples 1-3 is obtained, and it turns out that it can insert to an interdental space unreasonably.
