The open slots have a slot depth between the lower surface and the upper surface of about 0.10 mm to about 0.5 mm.
1. A shaving cartridge comprising:
a housing;
at least one blade mounted to the housing;
a guard having a plurality of spaced apart projections with an upper surface, the projections defining a plurality of open slots extending transverse to the blade, the open slots having a lower surface extending between the plurality of projections, wherein the open slots have a slot depth between the lower surface and the upper surface of about 0.10 mm to about 0.5 mm, wherein the lower surface between the projections has a radius of about 0.15 mm to about 1 mm.
2. The shaving cartridge of claim 1 wherein the upper surface of the projections is convex.
3. The shaving cartridge of claim 1 wherein the guard has a rearward edge in front of the blade and the plurality of spaced apart projections extend from a bottom edge of the guard up to and not beyond the rearward edge of the guard.
4. The shaving cartridge of claim 1 wherein the guard has a rearward edge in front of the blade and the slot depth measured at the rearward edge of the guard is about 0.20 mm to about 0.30 mm.
5. The shaving cartridge of claim 1 wherein the slot depth measured at a front face of the housing that is greater than the slot depth between the lower surface and the upper surface measured at a rearward edge of the guard that is located between the blade and the front face.
6. A shaving cartridge comprising:
a housing;
at least one blade mounted to the housing;
a guard having a plurality of spaced apart projections defining a plurality of open slots having a concave lower surface extending between the plurality of projections, the projections having a convex upper surface extending generally transverse to the at least one blade from a front face of the guard toward a rearward edge of the guard, wherein the upper surface and the lower surface form a continuous undulating skin contacting surface that extends along the length of the guard parallel to the at least one blade, wherein the lower surface of the guard has a radius of about 0.15 mm to about 1 mm.
7. The shaving cartridge of claim 6 wherein the projections extend and up to and not beyond the rearward edge of the guard.
8. The shaving cartridge of claim 6 wherein the slots have a depth between the lower surface and the upper surface of about 0.10 mm to about 0.5 mm measured at the rearward edge of the guard.
9. The shaving cartridge of claim 8 wherein the slots have a depth between the lower surface and the upper surface measured at the front face of the guard that is greater than the slot depth between the lower surface and the upper surface measured at the rearward edge of the guard.
10. The shaving cartridge of claim 6 wherein the plurality of spaced apart projections extend from a bottom edge of the guard to the rearward edge of the guard.
11. The shaving cartridge of claim 6 wherein the depth of the plurality of open slots at the rearward edge is the guard of about 0.20 mm to about 0.30 mm.
12. The shaving cartridge of claim 6 wherein the plurality of open slots have a slot width that increases from the front face of the guard toward the rearward edge of the guard.
13. The shaving cartridge of claim 6 wherein the projections have a width that decreases from the front face of the guard toward the rearward edge of the guard.
14. The shaving cartridge of claim 6 wherein the projections have a generally circular cross section.
