Razor cartridge
A razor cartridge comprising a first blade support and a second blade support, each of the first and second blade supports include a flat portion having a lower surface and a front end. A support plane S is tangent to the respective front ends of the first and second blade supports and the lower surface faces away from the support plane S. A first blade is attached to the lower surface of the flat portion of the first blade support. The first blade includes a first cutting edge. A second blade is attached to the lower surface of the flat portion of the second blade support. The second blade includes a second cutting edge. The first and second cutting edges are offset with respect to the support plane S.
1. A razor cartridge comprising:
a first blade support, a second blade support, and a third blade support, each of the first, second, and third blade supports including a flat portion having a lower surface a front end, wherein a support plane is tangent to the respective front ends of the first, second, and third blade supports, and the lower surface faces away from the support plane;
wherein each of the first, second, and third blade supports includes a base portion extending at an angle from the flat portion;
a first blade attached to the lower surface of the flat portion of the first blade support, wherein the first blade includes a first cutting edge;
a second blade attached to the lower surface of the flat portion of the second blade support, wherein the second blade includes a second cutting edge;
a third blade attached to the lower surface of the flat portion of the third blade support, wherein the third blade includes a third cutting edge;
wherein the first, second, and third cutting edges are offset with respect to the support plane,
wherein the third cutting edge is offset from the support plane in a direction opposite the direction the lower surface of the third blade support faces, and
wherein a distance between the first cutting edge and the second cutting edge is between 1.6 mm to 2.2 mm.
2. The razor cartridge of claim 1 , wherein the first cutting edge has a first cutting edge exposure and the second cutting edge has a second cutting edge exposure, wherein each of the first cutting edge exposure and the second cutting edge exposure is between −80 μm to +80 μm with respect to the support plane.
3. The razor cartridge of claim 2 , wherein the first and second cutting edge exposures are between −45 μm to +45 μm with respect to the support plane.
4. The razor cartridge of claim 2 , wherein at least one of the first and second cutting edge exposures is negative with respect to the support plane.
5. The razor cartridge of claim 2 , wherein at least one of the first and second cutting edge exposures is positive with respect to the support plane.
6. The razor cartridge of claim 1 , wherein a first distance between the first cutting edge and the front end of the first blade support and/or a second distance between the second cutting edge and the front end of the second blade support are/is within a range of 0.3 to 0.7 mm.
7. The razor cartridge of claim 6 , wherein the first and/or second distance are/is between 0.4 to 0.6 mm.
8. The razor cartridge of claim 6 , wherein the first and second distances are the same.
9. The razor cartridge of claim 6 , wherein the first and second distances are different.
10. The razor cartridge of claim 1 , wherein one or more of the front ends is rounded.
11. The razor cartridge of claim 1 , wherein the angle between the base portion and the flat portion is within a range of 104° to 120°.
12. The razor cartridge of claim 1 , further comprising a fourth blade support and a fifth blade support, each of the fourth and fifth blade supports including a flat portion having a lower surface and a front end, wherein the support plane is tangent to the respective front ends of the fourth and fifth blade supports and the lower surfaces face away from the support plane; wherein each of the fourth and fifth blade supports includes a base portion extending at an angle from the flat portion;
a fourth blade attached to the lower surface of the flat portion of the fourth blade support, wherein the fourth blade includes a fourth cutting edge; and
a fifth blade attached to the lower surface of the flat portion of the fifth blade support, wherein the fifth blade includes a fifth cutting edge;
wherein the fourth and fifth cutting edges are offset with respect to the support plane.
13. The razor cartridge of claim 12 , wherein a third distance between the fourth cutting edge and the front end of the fourth blade support and/or a fourth distance between the fifth cutting edge and the front end of the fifth blade support are/is within a range of 0.3 mm to 0.7 mm.
14. The razor cartridge of claim 12 , wherein the fourth and fifth cutting edges have respectively a fourth cutting edge exposure and a fifth cutting edge exposure that are in the range between −80 μm to +80 μm with respect to the support plane.
