  • Publication number: 20120030948
    Abstract: A shaving cartridge with a housing, a cap, and a guard. The guard has an upper surface. The cap has a top surface, a front edge, and an arcuate surface connecting the top surface and the front edge. A first blade between the cap and the guard has a cutting edge nearest the cap. A second blade between the cap and the guard has a cutting edge nearest the guard. The first and second blades define a blade plane tangent to the cutting edges. The blade plane is positioned below both (i) the surface of the guard and (ii) an intersection point of the front edge and the top surface of the cap.

  • Publication number: 20060179661
    Abstract: The invention features a shaving cartridge for connection to a handle. The shaving cartridge includes a plastic housing having a front portion, a rear portion having a rear surface, two side surfaces extending from the front portion to the rear portion, pivoting structure defining a pivot axis for pivoting of the housing with respect to the handle, and a housing axis extending from the rear portion to the front portion perpendicular to the pivot axis. One or more shaving blades are positioned between the front portion and the rear portion. The one or more blades extend along respective one or more parallel blade axes that are parallel to the pivot axis and located behind the pivot axis.
