<p>A blade cartridge (10) including three or more blades (30, 50, 70) fixed between a platform member (20) and a cap member (80). The present invention provides improved blade geometry where five contact surfaces (24, 34, 54, 74, 84) with the skin are considered, including the edges (32, 52, 72) of each blade, a guard member (22) and a cap member (80). The five contacting surfaces (24, 34, 54, 74, 84) are oriented at an equal distance from a common axis (14) in order to ensure that the shaving forces normal to the contacting surfaces (24, 34, 54, 74, 84) are shared by all the contacting surfaces (24, 34, 54, 74, 84). Additionally, the blades (30, 50, 70) of the present invention are movable to a less aggressive position in response to applied shaving forces. The arrangement of the present invention provides optimal blade geometry, thereby producing a close and comfortable shave.</p> |
