摘要： Razors cartridges including a guard, a cap, and at least two blades with parallel sharpened edges located between the guard and cap are provided. The first blade has a first color and a second blade has a second color, where the first color is different than the second color. The blade color corresponds to an attribute of the blade (e.g., low cut force) that the color is disposed on or an attribute of the razor cartridge (e.g., sensitive skin). The color of the blade corresponds to a target user of the razor cartridge (e.g., male or female). The first blade defines a blade edge near or nearest the guard and a second blade defines a blade edge near or nearest the cap.

摘要： The present invention relates to razor blade cutting edges and methods of producing edges exhibiting improved shave performance longevity and lower cutting forces. Conventional razor blades have increasing cutting forces with use due to the outer coating wear and adhesion loss. Blade edges produced according to the novel process exhibit significantly lower cutting forces when subjected to wool felt cutting shaving simulation, which correlates to more comfortable shaves initially and over the life of the blades. The present invention treats razor blade edges having a first adherent polyfluorocarbon coating with a first solvent to partially remove the polyfluorocarbon coating, adds a second polyfluorocarbon coating, heats, and treats the blade edge with a second solvent providing a final blade edge having a thin, uniform polyfluorocarbon coating. Preferred solvents include perfluoroalkanes, perfluorocycloalkanes, and perfluoroaromatic compounds having a critical temperature or boiling point above the dissolution temperature for the polyfluorocarbon in the solvent.
摘要翻译：本发明涉及剃刀刀片切割边缘和生产边缘的方法，其显示改进的剃刮性能寿命和较低的切割力。由于外涂层磨损和粘附损失，常规剃刀刀片在使用中具有增加的切削力。根据新工艺生产的刀刃在进行羊毛毡切割剃须模拟时表现出明显较低的切削力，这与最初和在刀片寿命期间更舒适的剃刮相关。本发明用第一溶剂处理具有第一粘附多氟烃涂层的剃刀刀刃，以部分地除去多氟烃涂层，加入第二多氟烃涂层，加热并用第二溶剂处理刀刃，从而提供具有薄的，均匀的聚氟碳涂层。优选的溶剂包括具有高于溶剂中多氟烃溶解温度的临界温度或沸点的全氟链烷烃，全氟环烷烃和全氟芳族化合物。
