Abstract

A shaving cartridge with a housing, having a primary guard at a front of the housing and a secondary cap at a rear of the housing. A bridge member having a primary cap surface and a secondary guard surface is positioned between the primary guard and the secondary cap. The bridge member has a plurality of spaced apart ribs extending transverse to the cutting edge of the first blade and defining a plurality of openings. A first blade has a cutting edge. The first blade is mounted to the housing between the primary guard and the primary cap surface. A second blade having a cutting edge extending in the same direction as the cutting edge of the first blade is mounted to the housing between the secondary guard surface and the secondary cap. A width of the bridge member is about 2.5 mm to about 4 mm.

Claims (14)

1. A shaving razor cartridge comprising:

a housing having a primary guard at a front of the housing and a secondary cap at a rear of the housing;

a bridge having an outer surface defining an opening;

a lubrication member positioned within the opening of the outer surface of the bridge, the lubrication member having a primary cap surface and a secondary guard surface positioned between the primary guard and the secondary cap;

a first blade having a cutting edge, the first blade mounted to the housing between the primary guard and the primary cap surface;

a second blade having a cutting edge extending in a same direction as the cutting edge of the first blade, the second blade mounted to the housing between the secondary guard surface and the secondary cap, wherein a width of the lubrication member is greater than 50% of an interblade span between the cutting edge of the first blade and the cutting edge of the second blade and the interblade span is greater than 3 mm and a width of the bridge member is about 2.5 mm to about 4 mm.

2. The shaving razor cartridge of claim 1 further comprising a blade support member mounted to the housing and the first blade is mounted to the blade support member wherein the bridge member is spaced apart from a blade support member to define a rinse channel.

4. The shaving razor cartridge of claim 1 wherein an outer surface of the lubrication member is not positioned on a same plane tangent to one of the cutting edges.

5. The shaving razor cartridge of claim 1 wherein an outer surface of the lubrication member is not positioned on a same plane tangent to both the cutting edges.

6. The shaving razor cartridge of claim 1 wherein an outer surface of the lubrication member defines a shave plane (P 1 ) about 0.01 mm to about 0.20 mm above a plane (P 3 ) tangent to the cutting edges.

7. The shaving razor cartridge of claim 1 wherein an outer surface of the lubrication member defines a shave plane (P 1 ) that is below a shave plane (P 3 ) tangent to the cutting edges.

8. The shaving razor cartridge of claim 7 wherein the plane (P 1 ) is about 0.01 mm to about 0.15 mm below the plane (P 3 ).

9. The shaving razor cartridge of claim 1 further comprising a pair of clips mounted to the housing, wherein an outer surface of the lubrication member defines a plane (P 1 ) between an outer surface of the clips and an inner surface of the clips.
