Description
図2を参照すると、カミソリ用カートリッジは、ガード10、キャップ12、及び2枚の刃14、16を有している。第1の刃14は、第2の刃16よりも高い切断抵抗を有し、ガードと第2の刃との間に配置されている。したがってカミソリの使用時には第1の刃14は第2の刃16よりも先に毛髪と接触することになる。第1の刃14は使用者の皮膚を通過する際に毛髪と接触し、これを引っ張ることによって毛髪を毛包の外部へと引き出し、所定の第1の長さに切断する。毛髪が元の位置にまで完全に引っ込む前に、第2の刃16が使用者の皮膚を通過して毛髪をより短い長さに再び切断する。切断後、毛髪は皮膚の表面下の毛包内に定位する。
カミソリの刃先をポリフルオロカーボンでコーティングする方法は当該技術分野において公知であり、例えばトランキーム(Trankiem)に付与された米国特許第5,263,256号に開示されている。ポリフルオロカーボンでコーティングされた刃先は、当該技術分野において知られるいずれの方法によっても製造することができる。例えば刃先をポリフルオロカーボンの分散液によりコーティングしてもよい。
テフロン(登録商標)のような表面摩擦が低く濡れ性が低い材料は、例えばプラズマエッチングなどによってその表面摩擦が徐々に増加するように改質することができる。プラズマの例としては、高周波(RF)プラズマや直流(DC)プラズマを挙げることができる。コーティングされた刃を適当な条件下でプラズマに曝露することで高分子コーティングに化学的及び物理的変化をもたらすことができる。こうした変化によって、これらに限定されるものではないが、粗さ、濡れ性、架橋、分子量といったいずれも刃の切断抵抗に影響する様々な性質(例、高分子の性質)に影響を与えることができる。
場合により、高分子でコーティングされていない刃をプラズマに曝露してこれにコーティングを成膜する。例えば、プラズマを用いてフッ素含有部分(例、CF2化学種)を刃に直接(例えばダイヤモンド状炭素などの硬質コーティング上に)成膜することによって切断抵抗が高い、コーティングされていない刃を切断抵抗の低い刃へと改質することができる。例えば高イオン衝突プラズマなどのプラズマ蒸着を用いることによって上記に述べた方法を用いて高分子(例、PTFE高分子)をコーティングした刃とは異なる性質を有する刃を得ることができる。
Claims (12)
- ガード、キャップ、及び、ガードとキャップとの間に配置される少なくとも2枚の平行かつ鋭利な刃先を有する刃を有する安全カミソリ刃ユニットを備えたカミソリであって、少なくとも2枚の刃は、異なる摩擦抵抗を与えるような異なる種類の高分子コーティングによりコーティングされ、少なくとも2枚の刃は、ガードに近い方の刃先を画定する第1の刃およびキャップに近い方の刃先を画定する第2の刃を有し、第1の刃の高分子コーティングは、第1の刃が第2の刃の切断抵抗よりも高い切断抵抗を有するように第1の刃の摩擦抵抗を増加させるよう改質された、少なくとも一部のコーティングからなり、第1の刃をコーティングする高分子組成物は第2の刃をコーティングする高分子組成物よりも潤滑性が低いことを特徴とするカミソリ。
- 第1の刃は第2の刃の切断抵抗よりも少なくとも0.44N(0.1lbs.)高い切断抵抗を有する請求項1に記載のカミソリ。
- 第1の刃は第2の刃の切断抵抗よりも0.44N(0.1lbs.)〜44N(10lbs.)高い切断抵抗を有する請求項1に記載のカミソリ。
- 前記高分子コーティングの少なくとも一つはポリフルオロカーボンである請求項1に記載のカミソリ。
- 前記ポリフルオロカーボンはポリテトラフルオロエチレンである請求項4に記載のカミソリ。
- 第2の刃は第1の刃よりも多量の高分子組成物によってコーティングされる請求項1に記載のカミソリ。
- 第1の刃の高分子コーティングはプラズマに曝露されることにより形成される請求項1記載のカミソリ。
- 第1の刃の高分子コーティングは電流に曝露されることにより形成される請求項1記載のカミソリ。
- 第1の刃の高分子コーティングはレーザーまたは電気ビームに曝露されることにより形成される請求項1記載のカミソリ。
- 少なくとも2枚の刃は、3枚の平行かつ鋭利な刃先を有する刃からなる請求項1記載のカミソリ。
- 第1の刃はガードに最も近い刃である請求項10記載のカミソリ。
- 第1の刃はガードに最も近い刃ではない請求項10記載のカミソリ。
