Abstract

La présente invention a trait à un rasoir à double lame pouvant être facilement nettoyé et simplement assemblé. Plus particulièrement, la présente invention a trait à un rasoir à double lame permettant d'agencer une ou plusieurs lames ayant des arêtes à double tranchant entre une partie de base et une partie de couvercle d'une tête, de former un ou plusieurs orifices de sortie sur les lames et la partie de base de manière à autoriser l'écoulement de l'eau de nettoyage et l'évacuation des résidus du rasage, de disposer des entretoises entre les lames de manière à ce que les orifices de sortie des lames ne soient pas bloqués par les entretoises, et de maximiser les zones des orifices de sortie, ce qui permet de nettoyer le rasoir de façon efficace et facile. De plus, les composants de la tête du rasoir sont assemblés à l'aide d'un moyen de couplage doté d'une tige de couplage intercalée entre la partie de base et la partie de couverture et à l'aide d'éléments de couplage disposés des deux côtés de la tête, ce qui permet de simplifier les procédures d'assemblage lors de la fabrication et ainsi de réduire les coûts de fabrication.
