View Patent ↗A razor cartridge comprising a housing; a guard located at the front of the housing; a cap located at the rear of the housing; two or more blades disposed in the housing between the guard and the cap; a skin contact element extending across the housing between two of said blades; and a plurality of projections extending from a base of said skin contact element, each having a skin contacting surface, the projections being spaced along the length of the skin contact element, wherein there is a pitch of up to 2 mm between adjacent projections and the skin contacting surface has a width extending for up to 35% of the pitch.
1. A razor cartridge comprising:
a) a housing ( 19 );
b) a guard ( 16 ) located at the front of the housing;
c) a cap ( 17 ) located at the rear of the housing;
d) a plurality of blades ( 12 ) disposed in the housing between the guard and the cap, each of said plurality of blades having a cutting edge, each cutting edge facing in the same direction;
e) a skin contact element ( 14 , 50 ) extending across the housing between two of said plurality of blades, and a rinse-through gap ( 23 ) immediately before and after the skin contact element wherein said skin contact element is not attached to any one of said plurality of blades disposed in the housing; and
f) a plurality of projections ( 51 ) extending from a base ( 52 ) of said skin contact element, each having a skin contacting surface ( 54 ), the projections being spaced along the length of the skin contact element, wherein there is a pitch ( 53 ) of up to about 2 mm between adjacent projections and the skin contacting surface has a width (w) extending for up to about 35% of the pitch.
2. The razor cartridge of claim 1 wherein the skin contact element comprises between about 15 and 150 projections.
3. The razor cartridge of claim 1 wherein the skin contacting surface is about 0.10 mm to 0.70 mm in width.
4. The razor cartridge of claim 1 wherein the width of the skin contacting surface extends for up to about 25% of the pitch.
5. The razor cartridge of claim 1 comprising slots ( 55 ) between adjacent projections, where the slots have a width of between 0.19 mm to 1.3 mm.
6. The razor cartridge of claim 1 wherein each projection has a depth of between about 0.3 mm to 2.5 mm.
7. The razor cartridge of claim 1 wherein the projections comprise a curved section ( 59 ) of up to about 0.3 mm in length and wherein the projections comprise a substantially flat portion on a top face ( 58 ) of up to 0.6 mm in length.
8. The razor cartridge of claim 1 wherein the distance between two adjacent blade edges is less than 1.0 mm.
9. The razor cartridge of claim 1 wherein the projections have a height of from about 0.25 mm to 1.00 mm.
10. The razor cartridge of claim 1 wherein the blade tangent angle ( 48 ) of the blade following the skin contact element ranges from about 25 to 40 degrees.
11. The razor cartridge of claim 1 , wherein said skin contact element is disposed in a blade position.
