CA 2726584

The invention provides a razor cartridge (10) with multiple blades (25) and peg(s) (74) or pegged support members (72) that aid in the control of the blades by restricting fore and aft blade movement, which in turn, reduces the amplitude of blade deflection and/or vibration during shaving. This reduction provided by the pegs improves shaving performance. Blades rest between pegs which are rounded or shaped such that the blade bottom portion contacts the peg at one point, forming a single line of contact. The pegs may be in a slalom-like, linear (with one or more peg columns), or offset arrangement. Pegs or pegged support members may be at any location of the razor blade assembly; for instance, at the center and/or at blade slot ends. Pegs may each be of different shapes and may or may not be equidistant or at the same heights as each other, depending on blade spans and exposures.

Linvention concerne une cartouche de rasoir (10) équipée de multiples lames (25) et de cheville(s) (74) ou déléments de support chevillés (72) contribuant à contrôler les lames en limitant leur mouvement vers lavant et vers larrière, ce qui réduit lamplitude de la déviation et/ou de la vibration des lames pendant le rasage. Cette réduction fournie par les chevilles améliore la performance de rasage. Les lames reposent entre des chevilles qui sont arrondies ou formées de sorte que la partie inférieure de la lame vienne en contact avec la cheville en un point, formant ainsi une ligne unique de contact. Les chevilles peuvent présenter un agencement ondulé, linéaire (avec une ou plusieurs colonnes de chevilles), ou décalé. Les chevilles ou les éléments de support chevillés peuvent se trouver en tout emplacement sur lensemble lames de rasoir ; par exemple, au centre et/ou sur les extrémités des fentes des lames. Les chevilles peuvent présenter différentes formes et peuvent ou non être équidistantes ou aux mêmes hauteurs, en fonction de lespacement des lames et de leur exposition.
