Title (EN) SHAVING SYSTEMS AND FOILS
(FR) SYSTEMES ET FEUILLES METALLIQUES DE RASAGE
Abstract:
(EN) A shaving cutter (111) comprises a skin-engaging surface (116) having both a convex elliptic region (116a) and a hyperbolic region (116b). The elliptic region merges with the hyperbolic region along a parabolic transition region (117). Preferably, at least one of the surface regions is perforate. In addition, a concave parabolic skirt region (114) may depend from the hyperbolic region, while a convex parabolic skirt region (115) depends from the elliptic region. Methods of manufacturing the shaving cutter are also described.
(FR) Cette feuille métallique de rasage (111) comprend une surface (116) entrant en contact avec la peau et présentant une région elliptique (116a) ainsi qu'une région hyperbolique (116b). La région elliptique fusionne avec la région hyperbolique le long d'une région de transition (117). De préférence, l'une au moins de ces régions de surface est perforée. En outre, une jupe parabolique et concave (114) peut partir de la région hyperbolique, tandis qu'une jupe parabolique et convexe (115) part de la région elliptique. L'invention concerne également des procédés de fabrication de cette feuille métallique de rasage.
