Abstract

Disclosed here are shaving razor systems and methods including razor cartridges with a unitary frame having a length and width, a topside and an underside, wherein the unitary frame includes angled joints or bends connecting at least three guards running lengthwise on the unitary frame, the guards separated by at least three gaps in the frame, and at least three blades, affixed to the underside of the guards of the unitary frame, wherein the at least three blades include edges, and wherein the blade edges extend into the gaps in the frame when affixed to the underside of the guards of the unitary frame.

Claims (25)

1. A shaving razor system, comprising:

a cartridge housing having a length and a width, a first cartridge side defined by the length and width and a second cartridge side defined by the length and width, and a depth separating the first side and the second side,

wherein the first cartridge side includes a cap generally across the length and a guard generally across the length,

wherein the cartridge housing includes at least three substantially flat blades mounted into the cartridge housing generally across the length of the housing between the cap and the guard, and generally parallel to the cap and the guard, each blade including a blade edge,

wherein exposure is measured for each of the at least three blade edges against parallel imaginary exposure reference lines drawn across the first side of the cartridge width from the cap to the guard at each of two locations along the length of the cartridge, and

wherein exposure of a first blade of the at least three blades is different at a first imaginary exposure reference line of the two locations along the length of the cartridge, from a second of the two imaginary exposure reference line locations along the length of the cartridge, and

wherein exposure of a second blade of the at least three blades is different at the first imaginary exposure reference line of the two locations along the length of the cartridge, from the second of the two imaginary exposure reference line locations along the length of the cartridge, and

wherein exposure of the third blade of the at least three blades is different at the first imaginary exposure reference line of the two locations along the length of the cartridge, from the second imaginary exposure reference line of the two locations along the length of the cartridge.

2. The shaving razor system of claim 1 wherein, the at least three blades mounted into the cartridge housing is by a unitary frame.

3. The shaving razor system of claim 1 wherein, at least three blades mounted into the cartridge housing is by individual razor supports.

4. The shaving razor system of claim 1 wherein, the cap is not a uniform flat surface.

5. The shaving razor system of claim 1 wherein, the guard includes ridges.

6. The shaving razor system of claim 1 wherein, the blades are coated in PTFE.

7. The shaving razor system of claim 1 wherein, the at least three blades is four.

8. The shaving razor system of claim 1 wherein, the at least three blades is six.

9. The shaving razor system of claim 1 wherein, the cap is made of a lubricious material.

10. The shaving razor system of claim 9 wherein, the lubricious material wears away during use, thereby changing the exposure of the at least three blades.

11. A shaving razor system, comprising:

a cartridge housing, when in an upright position, having a length and a width, a topside and an underside,

wherein the cartridge housing first side includes a cap generally across the length of a first side of the topside and a guard generally across the length of a second side of the topside,

wherein the cartridge housing includes at least three substantially flat blades mounted into the cartridge housing generally across the length of the housing between the cap and the guard, and generally parallel to the cap and the guard, each blade including a blade edge,

wherein exposure is measured for each of the at least three blade edges against a first and second parallel imaginary exposure reference lines drawn across the top side of the cartridge width from a highest point of the cap to a highest point of the guard, and

wherein exposure of a first blade of the at least three blades is different at the first imaginary exposure reference line of the two locations along the length of the cartridge, from the second of the two imaginary exposure reference line locations along the length of the cartridge, and

wherein exposure of a second blade of the at least three blades is different at the first imaginary exposure reference line of the two locations along the length of the cartridge, from the second of the two imaginary exposure reference line locations along the length of the cartridge, and

wherein exposure of the third blade of the at least three blades is different at the first imaginary exposure reference line of the two locations along the length of the cartridge, from the second imaginary exposure reference line of the two locations along the length of the cartridge.
