Title
(EN) TRIPLE-BLADE SAFETY RAZOR
(FR) RASOIR DE SURETE A TROIS LAMES
Abstract
(EN)
A disposable safety razor (Fig. 1) uncludes a handle (10), a head (12) formed integrally with the handle (10), and three parallel stainless blades (14, 16, 18) fixed in the head (12). The cutting edges lie in a common plane making an acute angle with respect of each blade (14/16/18), and the blades (14, 16, 18) are separated by spacers (15, 17) of unequal thickness, so that the leading and middle blades (14, 16) are more closely spaced than the middle and trailing blades (16, 18). Improved shave quality and blade duration is observed.
(FR)
L'invention porte sur un rasoir de sûreté (figure 1) constitué d'un manche (10), d'une tête (12) solidaire du manche (10), et de trois lames inoxydables (14, 16, 18) parallèles fixées à la tête (12). Les bords tranchants sont disposés sur un plan commun formant un angle aigu par rapport à chaque lame (14, 16, 18), et les lames (14, 16, 18) sont séparées par des espaceurs (15, 17) d'inégale épaisseur, si bien que l'espace entre la lame d'attaque et la lame du milieu (14, 16) est moins grand que l'espace entre la lame du milieu et la lame traînante (16, 18). Le rasoir de l'invention offre une qualité de rasage et une durée de vie des lames améliorées.
