Claims
- 1. A replaceable blade cartridge shaving system comprising:
- an elongated handle member having a head portion extending transversely thereof, the head portion including a pair of longitudinally extending co-planar opposed flange members extending substantially perpendicular to the head portion and a substantially rigid protuberance member located medially of the flanges and extending a predetermined significant distance beyond the plane containing the flanges; and
- a replaceable blade cartridge having coupling structure defining two opposed spaced grooves adapted for longitudinal slidable engagement with the flange members for attaching the cartridge to the handle in a desired shaving position, and a clearance recess between the coupling grooves for accepting the protuberance member when the cartridge is slidingly coupled to the handle, said protuberance member having a particular geometry transversely of the longitudinal extent of said flange members, and the geometry of said clearance recess transversely of the longitudinal extent of said cartridge being sufficient to clear said protuberance member at least from one end of said cartridge continuously to a position enabling said attachment of said cartridge with said handle in said desired shaving position.
- 2. The system of claim 1 wherein the protuberance member is substantially co-extensive with the flange members.
- 3. The system of claim 2 wherein the flange members include a substantially "U" shaped member having side walls upstanding from a base portion affixed to the head and longitudinally co-extensive therewith, and the protuberance member extends medially of the side walls and is of substantially rectangular cross-section.
- 4. The system of claim 3 wherein the head terminates in a planar surface having at least one post member upstanding therefrom, the post member being in registration with and extending through a complementary aperture in the base portion and into a complementary recess in the protuberance member and is affixed thereto.
- 5. The system of claim 4 wherein there are two post members affixed to the base portion and protuberance member.
- 6. The system of claim 5 wherein the head and the protuberance member are made of plastic and ultrasonically welded together.
- 7. The system of claim 2 wherein the head, the protuberance member and the flange member are integrally molded of plastic material.
- 8. The system of claim 1 wherein the head has a trapezoidal cross-section and terminates in a planar surface forming the larger base thereof, and the flange member comprises a substantially "U" shaped member having side walls upstanding from a base portion in contact with the surface and with flanges extending outwardly normally of the side walls, and tang members extending from the base portion for affixing the flange member to the head when the tang members are bent into contact with longitudinal surfaces of the trapezoidal shaped terminal end.
- 9. The system of claim 8 wherein the side walls extend from the base portion toward the handle, and the protuberance member comprises the base portion with the flange member affixed thereto.
