Description

本発明は一般的には口腔衛生に関し、より詳しくは、隣接歯間表面の予防処置及び歯肉の刺激のための器具に関する。   The present invention relates generally to oral hygiene, and more particularly to a device for prophylactic treatment of the interproximal surface and gingival stimulation.

口腔衛生プログラムにおいては、定期的にブラッシングをすることが主たる要素を構成するが、ブラッシングは針毛が届くことができる歯の表面、すなわち、舌側の表面、唇側の表面、頬側の表面、 咬合面及び切面に関してのみ有効であった。   In an oral hygiene program, regular brushing constitutes the main element, but brushing is the surface of the tooth that the needle hair can reach, ie the lingual surface, the labial surface, the buccal surface Only effective for occlusal and cut surfaces.

歯間部の洗浄は、デンタルフロス及び爪楊枝に頼ってきた。デンタルフロスはしばしば、特に、隙間なく接した歯の歯間面を洗浄又は綺麗にしようとする時、使用が困難であった。親指と小指とを張った長さのフロスをしっかり掴み、張力をかけ、該張力のかかったフロスを歯肉接合部へ向けて押し入れる。教示のフロスが該接触面を通り越すとき、該フロスがプツンと切れ、該歯肉に強く当たり、切傷、創傷、炎症を引き起こす傾向があった。   Interdental cleaning has relied on dental floss and toothpicks. Dental floss is often difficult to use, especially when trying to clean or clean the interproximal surfaces of the teeth that touched without gaps. Grasp the length of the floss with the thumb and little finger tight, apply tension, and push the tensioned floss towards the gingival junction. When the taught floss passed over the contact surface, the floss plunged and struck the gums apt to cause cuts, wounds, and inflammation.

更に、該フロスを咬合平面の方向に引っ張って取り除こうとする時、例えば歯冠のような、歯の修復物を除去してしまう危険があった。   Furthermore, when the floss is pulled away in the direction of the occlusal plane, there is a risk of removing a dental restoration, such as a dental crown.

木製の爪楊枝は異なる欠点を有する。木製の爪楊枝の形状は通常、機能よりもむしろ、製造上の理由によって決定される。木の持つ吸収性により、雑菌混入に関する問題があり、木は潜在的に裂ける危険があった。   Wooden toothpicks have different drawbacks. The shape of a wooden toothpick is usually determined by manufacturing reasons rather than function. Due to the absorbency of the tree, there was a problem with contamination and the tree could potentially tear.

米国意匠第382,368号で開示されているような成形したプラスチックの爪楊枝は、単一の歯間ブラシと組み合わせることにより、歯間を綺麗にするためのくさび状の突起の有利性を提供した。しかし、歯肉への潜在的な傷害を減らすと同時に、食物残査、プラーク、白質、初期の歯石等をより効果的に除去する必要があった。   Molded plastic toothpicks as disclosed in US Design No. 382,368, in combination with a single interdental brush, provided the advantage of a wedge-shaped protrusion for clean- ing the teeth. However, there was a need to more effectively remove food residues, plaque, white matter, early calculus and the like while reducing potential injury to the gums.

発明の概要
成形した熱可塑性プラスチック口腔衛生器具は、一端に歯間ブラシを有する中心柄を含み、他端に先の細くなったくさびを含む。 SUMMARY OF THE INVENTION A molded thermoplastic oral hygiene device includes a central handle having an interdental brush at one end and a tapered wedge at the other end.

該歯間ブラシは段階的な長さの針毛を平面状の魚の骨状に配列して有する軸方向の羽柄を含む。段階的な長さの針毛は、歯間及び歯周ポケットを洗浄すると同時に、創傷を最小限にしながら歯肉表面を刺激するのに適している。   The interdental brush includes an axial feather having stepped lengths of bristles arranged in the shape of a flat fish bone. The graded length of bristle is suitable for cleaning the interdental and periodontal pockets while simultaneously stimulating the gingival surface while minimizing wounds.

該先の細くなったくさびは、横に湾曲した背骨及び対向する横側面を含み、それぞれの横側面は、横断する三面体のリブを間隔を空けた配列で有する。該リブの鋭利な縁は、該器具を歯間内で軸方向の往復運動で操作する時、隣接面及び隣接歯間面から白質、菌膜、プラーク、初期の歯石、食物残査等を除去するのに効果的である。該湾曲した背骨は、歯肉の創傷の可能性を減少させる。   The tapered wedge includes a laterally curved spine and opposing lateral sides, each lateral side having transverse trihedral ribs in a spaced arrangement. The sharp edges of the ribs remove white matter, fungus, plaque, early tartar, food residues, etc. from the adjacent and adjacent interdental surfaces when the appliance is manipulated by axial reciprocation within the teeth. It is effective. The curved spine reduces the likelihood of gingival wounds.

該柄は通常円筒の形状であるが、該針毛及び該先の細くなったくさびの共通の軸面と平行な面に横たわる一対の側面を持つ。該側面は掴み面としての役割を果たし、使用者が該歯間ブラシ及び該先の細くなったくさびの双方の向きを決める際の手助けをする。   The handle is generally cylindrical in shape, but has a pair of sides lying on a plane parallel to the common axial plane of the bristles and the tapered wedge. The side surface serves as a gripping surface and assists the user in orienting both the interdental brush and the tapered wedge.

好ましい具体例の説明
同じ番号は一貫して同じ部品を示した図を詳細に参照する。参照番号１０は本発明に従い、本発明を例示するように構成された口腔衛生器具を一般に示す。該口腔衛生器具は、中心に概ね円筒状の柄１２を含む。柄１２の一端から軸方向に歯間ブラシ１４が突き出しており、一方、先の細くなったくさび１６が柄１２の反対側の端から軸上に延びている。本発明に従って、該口腔衛生器具１０は一体形成可塑性プラスチック構成で製造される。 DESCRIPTION OF PREFERRED EMBODIMENTS Reference will now be made in detail to the drawings, in which like numerals consistently refer to like parts. Reference numeral 10 generally indicates an oral hygiene device configured in accordance with the present invention to exemplify the present invention. The oral hygiene device includes a generally cylindrical handle 12 in the center. An interdental brush 14 protrudes axially from one end of the handle 12, while a tapered wedge 16 extends on the shaft from the opposite end of the handle 12. In accordance with the present invention, the oral hygiene device 10 is manufactured in an integrally formed plastic plastic configuration.

図１、図２及び図4を注目すると、歯間ブラシ１４は軸方向の羽柄１８及び平面状で実質的に対称な配列２０の柔軟な針毛を含むことが認められるであろう。該配列２０の針毛は実質的に1つの平面２２内にある。図２に最も良く描かれているように、配列２０は実質的に魚の骨又はひし形形状をしており、最も短い長さを持つ先頭及び後端の針毛２４、漸次長さが長くなる針毛２６、２８、３０及び最も長い中心の針毛３４を含む。   Referring to FIGS. 1, 2 and 4, it will be appreciated that the interdental brush 14 includes an axial wing 18 and a planar, substantially symmetrical array 20 of flexible bristles. The bristles of the array 20 are substantially in one plane 22. As best depicted in FIG. 2, the array 20 is substantially in the shape of a fish bone or rhombus, with leading and trailing needle hairs 24 having the shortest length, progressively longer needles. The bristles 26, 28, 30 and the longest central stylus 34 are included.

該羽柄１８は後部歯間部まで完全に届くように10mmから15mmのオーダーの長さを持つ。更に、該後端の針毛２４は該柄１２の端から約4mmから5mmの距離だけ間隔を空けている。このようにして、実質的に全ての針毛は後部歯間部を横断することができ、歯の舌側面に関与することができる。   The wing pattern 18 has a length on the order of 10 mm to 15 mm so as to reach the rear interdental part completely. In addition, the trailing end bristle 24 is spaced from the end of the handle 12 by a distance of about 4 mm to 5 mm. In this way, substantially all the bristle can cross the back interdental region and can participate in the lingual side of the tooth.

該羽柄の直径は0.5mmから0.8mmのオーダーであり、好ましくは柄の端つまり基部の直径約0.7mmから先端の直径約0.5mmとなるように先が細くなり、これにより、歯間部の通路を確保する。   The diameter of the stalk is on the order of 0.5 mm to 0.8 mm, and preferably the taper is tapered so that the diameter of the end of the handle, that is, the base is about 0.7 mm, and the diameter of the tip is about 0.5 mm. Secure the passage.

針毛２４から針毛３４は柔らかく、柔軟で好ましくは厚さ又は直径が0.2mmのオーダーであり、羽柄１８部の0.2mmから端部の0.1mmとなるように先が細くなっても良い。   The needle hairs 24 to 34 are soft and flexible and preferably have a thickness or diameter on the order of 0.2 mm, and may be tapered from 0.2 mm at the 18-feather pattern to 0.1 mm at the end. .

例として、先頭及び後端の針毛２４のそれぞれは該羽柄１８から約0.7mmの距離だけ突き出しており、一方、中心の針毛３４は該羽柄１８から約1.7mmの距離突き出している。   As an example, each of the leading and trailing needle hairs 24 protrudes from the feather pattern 18 by a distance of about 0.7 mm, while the central needle hair 34 protrudes from the feather pattern 18 by a distance of about 1.7 mm. .

該柄１２の反対の端において、該先の細くなったくさび１６がナイフの形状と同様の形状で構成されており、該柄の端から約2cm突き出している。   At the opposite end of the handle 12, the tapered wedge 16 is constructed in a shape similar to that of a knife and protrudes about 2 cm from the end of the handle.

該くさび１６は図６に示すように、湾曲した周縁表面を有する直線状の背骨３８を含む。該湾曲した表面は歯肉の切創、炎症、創傷等が起こる傾向を低くする。該先の細くなったくさび１６は1対の傾斜した横側面４０、４２を含み、それらは規定された端縁４４に沿って交わる。該端縁４４は尖った先端４６まで傾斜しており、その先端は該端縁４４及び横方向に湾曲した背骨３８との接合点を構成する。   The wedge 16 includes a straight spine 38 having a curved peripheral surface, as shown in FIG. The curved surface reduces the tendency for gingival cuts, inflammation, wounds and the like to occur. The tapered wedge 16 includes a pair of inclined lateral sides 40, 42 that meet along a defined edge 44. The edge 44 is slanted to a pointed tip 46 that constitutes the junction of the edge 44 and the laterally curved spine 38.

図５及び図６の検討から言及されるように、背骨３８の最大の横断幅は、該側面４０、４２の間の対応する距離をわずかに超えて延びている。傾斜のついた肩４６、４８は該側面の基部から湾曲した該背骨３８へ向けて外側に延びている。   As noted from the discussion of FIGS. 5 and 6, the maximum transverse width of the spine 38 extends slightly beyond the corresponding distance between the side surfaces 40, 42. Inclined shoulders 46, 48 extend outwardly from the lateral base toward the curved spine 38.

本発明に従って、横向きに配列した三面体のリブ５０が該側面４０、４２から突き出ている。リブ５０のそれぞれは、掻き取り端縁５６に沿って交差する一対の先の細くなった側壁５２、５４によって構成される。三面体のリブ５０の該側面５２、５４は該側面４０、４２の端縁４４から一定の距離を空けた場所から延びている。該三面体のリブは肩４６、４８の接合点に形成された基部で終わる。該掻き取り端縁５６は該三面体のリブの基部において背骨３８の幅より少し横に突き出している。   According to the present invention, laterally arranged trihedral ribs 50 protrude from the side surfaces 40, 42. Each of the ribs 50 is constituted by a pair of tapered side walls 52, 54 that intersect along the scraping edge 56. The side surfaces 52, 54 of the trihedral rib 50 extend from a distance from the edge 44 of the side surfaces 40, 42. The trihedral ribs terminate at the base formed at the junction of the shoulders 46,48. The scraping edge 56 protrudes slightly laterally beyond the width of the spine 38 at the base of the trihedral rib.

該三面体のリブ５０同士の間隔は、好ましくは該三面体のリブ５０の最大幅より広い0.8mmのオーダーであり、これにより、プラーク、白質、菌膜、食物残査及び初期の歯石ような、器具１０を用いて口腔から除去するための掻き集められた物質が堆積するのに十分な領域が提供される。   The spacing between the trihedral ribs 50 is preferably on the order of 0.8 mm, which is wider than the maximum width of the trihedral ribs 50, such as plaque, white matter, fungus film, food residue and early tartar. Sufficient area is provided for depositing the scraped material for removal from the oral cavity using the instrument 10.

図１及び図2に注目すると、柄１２は一対の平行な平面の側板５８，６０が窪んだ状態であることを除いて、概ね円筒状であることが認められるであろう。側板５８、６０は軸面２２と平行な平面内にある。従って、親指と人差し指の間に側板５８、６０を掴んで器具１０を持つことができ、歯間部に挿入する際、該器具を詳しく調べる必要なしに、鏡も必要とせずに、該針毛配列２０及び該先の細くなっているくさび１６の向きがわかる。   1 and 2, it will be appreciated that the handle 12 is generally cylindrical except that the pair of parallel planar side plates 58, 60 are recessed. The side plates 58 and 60 are in a plane parallel to the axial surface 22. Therefore, the side plate 58, 60 can be grasped between the thumb and the index finger to hold the device 10, and when inserting it into the interdental portion, it is not necessary to examine the device in detail, and a mirror is not required. The orientation of the array 20 and the tapered wedge 16 is known.

該先の細くなった魚の骨又は菱形の形状の針毛配列２０により、歯間部に挿入する時、また歯間部から引き出す時にも、先頭及び後端の最も短い針毛２４が最初に歯間部と係合し、次に漸次より大きな針毛が係合することを確保する、ということもまた認められるであろう。従って、挿入及び引き出しに必要な苦労が最小化される一方、同時に歯肉の創傷の可能性も減少する。   With the tapered fish bone or diamond-shaped needle hair array 20, the shortest head hair 24 at the beginning and the rear end is the first tooth when inserted into the interdental region or pulled out from the interdental region. It will also be appreciated that it engages the interspace and then ensures that progressively larger bristle is engaged. Thus, the effort required for insertion and withdrawal is minimized while at the same time the likelihood of gingival wounds is reduced.

該先の細くなったくさび１６において、歯間部内を軸方向に往復運動することにより、該三角体のリブ５０に連続的に間隔を置いて配置された掻き取り端縁５６が、歯間部と定義される対向する隣接面と接触し、掻き取り、及びこのような面からプラーク、白質、食物残渣等を除去することとなる。該掻き取られた物質は隣接する三角体のリブの間のスペースに蓄積する。   In the tapered wedge 16, the scraping edge 56 continuously spaced from the rib 50 of the triangular body is reciprocated in the interdental portion in the axial direction so that the scraping edge 56 is interdental. Will contact, scrape and remove plaque, white matter, food debris, etc. from such surfaces. The scraped material accumulates in the space between adjacent triangular ribs.

多数ある熱可塑性プラスチックのいずれをも一体形口腔衛生器具１０の射出成形に利用できるが、Polyplastics Taiwan Co., Ltd. から入手できるTepcon M450のようなポリオキシメチレン（POM）コポリマーが、本発明における実施によく適合し、歯間ブラシの細かい規定を維持しつつ十分な柔軟性を確保する。   Although any of a number of thermoplastics can be used for injection molding of the integrated oral hygiene device 10, a polyoxymethylene (POM) copolymer such as Tepcon M450 available from Polyplastics Taiwan Co., Ltd. is used in the present invention. It fits well in practice and ensures sufficient flexibility while maintaining the fine provisions of the interdental brush.

従って、本発明の種々の局面、特徴、目的を達成する口腔衛生器具が提供され、これは実際上の使用の条件を満たすのに好適であると理解できるであろう。   Accordingly, it will be appreciated that an oral hygiene device that achieves various aspects, features, and objectives of the present invention is provided, which is suitable to meet the conditions of practical use.

本発明の趣旨を離れない範囲で、種々の可能な実施例を本発明から作成することができ、本明細書に記載した典型的な実施例において種々の変更を行なうことができるが、本明細書において記載され、添付した図面で示した全ての事項は、限定されない例として理解されるべきである。   Various possible embodiments can be made from the present invention without departing from the spirit of the present invention, and various changes can be made in the exemplary embodiments described herein.
