<p>The present disclosure is directed to a shaving cartridge (10) for use with a razor handle (12) having a pair of cartridge engaging shell rocker bearings (14, 16) biased toward one another each of which has at least one undercut rocker bearing (18, 20) for receiving the cartridge (10). The cartridge (10) has at least one blade thereon and has curved under surfaces (48, 50) pivotal upon and relative to the rocker bearing surfaces (18, 20) of the cartridge engaging shell rocker bearings (14, 16). At least one protrusion (52, 54) extends from the curved under surfaces (48, 50) of the cartridge (10) and is positioned to engage the shell rocker bearing surfaces (14, 16) when the cartridge (10) is introduced to the shell bearings (14, 16) of the handle (12) to avoid reverse insertion of the cartridge (10) in the handle (12).</p> |
