Shaving Aid Geometry for Wet Shave System
The invention discloses a novel geometry for a lubricating body, strip or cap, composed of shaving aids, taking into consideration their shape, materials and placement along with their interaction with multiple blades for improved shaving attributes in a wet shaving system. A strip exposure and a strip angle is disclosed where generally a maximum height of the lubricating strip is greater than or equal to the maximum height of the blade plane.
1 . A razor cartridge comprising:
a plurality of blades and at least one lubricating body in the dry state, said body having a maximum height greater than or equal to a maximum blade plane height of said plurality of blades.
2 . The razor cartridge of claim 1 wherein the lubricating body is a lubricating strip.
3 . The razor cartridge of claim 1 wherein the lubricating body is a cap.
4 . The razor cartridge of claim 1 wherein the lubricating body is a coated cap.
5 . The razor cartridge of claim 1 wherein said at least one lubricating body can be any shape.
6 . The razor cartridge of claim 1 wherein said plurality of blades are of any type.
7 . The razor cartridge of claim 1 wherein said plurality of blades are low cutting force (sharp) blades.
8 . The razor cartridge of claim 1 wherein said plurality of blades are at the same height.
9 . The razor cartridge of claim 1 wherein said plurality of blades are at different heights.
10 . The razor cartridge of claim 1 wherein said lubricating body is in contact with fluid.
11 . The razor cartridge of claim 1 wherein said lubricating body maximum height is greater than or equal to a height of a blade or blades most proximal to said lubricating body.
12 . A razor cartridge comprising:
a plurality of blades and at least one lubricating body in the dry state having a strip exposure greater than or equal to −0.10 millimeters.
13 . The razor cartridge of claim 12 further comprising a strip angle greater than or equal to zero degrees.
14 . The razor cartridge of claim 12 wherein said strip exposure is between about 0.00 mm and about 0.10 mm.
15 . The razor cartridge of claim 12 wherein said strip exposure is between about −0.10 mm and about 0.00 mm.
16 . The razor cartridge of claim 13 wherein said strip angle is between about 0 degrees and about 10 degrees.
17 . The razor cartridge of claim 12 wherein said lubricating body is a strip.
18 . The razor cartridge of claim 12 wherein said lubricating body is a cap.
19 . The razor cartridge of claim 12 wherein said lubricating body comprises any shape.
20 . The razor cartridge of claim 12 wherein said plurality of blades are of any type.
21 . The razor cartridge of claim 12 wherein said plurality of blades are of mixed type.
22 . The razor cartridge of claim 12 wherein said plurality of blades are at the same height.
23 . The razor cartridge of claim 12 wherein said plurality of blades are at different heights.
24 . The razor cartridge of claim 12 wherein said lubricating body is in contact with fluid.
25 . The razor cartridge of claim 12 wherein said strip exposure is relative to a blade or blades of said plurality of blades most proximal to said lubricating body.
26 . A razor cartridge comprising:
a plurality of blades and at least one lubricating body having a strip exposure greater than or equal to −0.10 millimeters and a strip angle greater than or equal to zero degrees in the dry state.
