  • These are loose razor blades suitable for being placed, in removable condition, on the well-known elongated handle machines.

Abstract

L'invention concerne un rasoir du type qui utilise des cartouches amovibles porteuses des unités de coupe (lames à raser) montées dans des conditions telles que leurs chants à bord affûté se projettent vers l'extérieur de manière dûment orientée pour effectuer le rasage lorsque la machine se déplace raisonnablement sur la peau de l'utilisateur. Ledit rasoir comprend une tête fixe (1) à l'intérieur de laquelle est logée une cartouche rotative (2) porteuse d'une pluralité d'unités de coupe à double arête qui sont distribuées au niveau de faces de rasage correspondantes définies dans le corps de la cartouche, chacune desquelles se plaçant en conditions d'utilisation lorsqu'elle fait face à une fenêtre frontale (5) définie dans la tête fixe. La cartouche est un corps allongé de forme parallélépipédique, qui possède une pluralité de faces principales, de préférence rectangulaires, définies entre deux faces latérales plus petites, dans lesquelles sont montées les unités de coupe, chacune desquelles possède deux arêtes longitudinales égales et parallèles légèrement séparées entre elles, quatre arêtes de coupe parallèles étant ainsi constituées sur chaque face, réparties de manière ordonnée l'une sous l'autre. Les unités de coupe à double arête longitudinale présentent une certaine élasticité structurale et sont logées, avec une certaine justesse dans des gorges droites et longiformes qui s'étendent dans chacune des faces de rasage de la cartouche rotative. Chaque unité de coupe est définie par un corps longiforme, droit et allongé de section transversale en "U", des oreilles obliques, parallèles entre elles, qui s'étendent d'une extrémité à l'autre, faisant saillie à partir desdits bords libres.
