Abstract

A shaving razor cartridge with a housing having a guard and a cap. A pair of laterally spaced apart blade stabilizers are on the housing. A primary blade member is positioned between the guard and the cap. A blade retention member is mounted to a top surface of the housing. The primary blade member has a cutting edge constrained between the blade retention member and the pair of laterally spaced apart blade stabilizers.

Claims (19)

1. A shaving razor cartridge comprising:

a housing having a pair of laterally spaced apart blade stabilizers, a guard, and a cap;

a primary blade positioned between the guard and the cap, wherein the primary blade having a cutting edge, a vertical base and a bent portion between the cutting edge and the vertical base;

a blade retention member mounted to a top surface of the housing, wherein the cutting edge of the primary blade is constrained between the blade retention member and the pair of laterally spaced apart blade stabilizers, wherein the cutting edge of the primary blade directly contacts the pair of laterally spaced apart blade stabilizers and the blade retention member, wherein the blade stabilizers are spaced apart from the vertical base; and

wherein the pair of laterally spaced apart blade stabilizers directly contact the blade retention member.

2. The shaving razor cartridge of claim 1 wherein the pair of laterally spaced apart blade stabilizers are positioned directly under the corresponding blade retention members.

3. The shaving razor cartridge of claim 1 further comprising a plurality of blade members positioned between the primary blade and the cap.

4. The shaving razor cartridge of claim 3 wherein each of the plurality of blade members has a respective cutting edge that is unsupported.

5. The shaving razor cartridge of claim 1 wherein the pair of laterally spaced apart blade stabilizers comprise an elastomeric material.

6. The shaving razor cartridge of claim 1 wherein the pair of laterally spaced apart blade stabilizers are positioned between a front interior wall of the housing and the vertical base of the primary blade.

7. The shaving razor cartridge of claim 6 wherein the pair of laterally spaced apart blade stabilizers extend from the front interior wall of the housing and are spaced apart from the vertical base of the primary blade.

8. The shaving razor cartridge of claim 1 wherein a portion of the cutting edge of the primary blade is depressed into the pair of laterally spaced apart blade stabilizers.

9. The shaving razor cartridge of claim 1 wherein the blade stabilizers comprise a material having a Shore A hardness of 30 to 60.

10. The shaving razor cartridge of claim 1 wherein the pair of laterally spaced apart blade stabilizers each comprise at least one protrusion having a height of about 0.25 mm to about 0.50 mm from a base to a top surface of the protrusion.

11. The shaving razor cartridge of claim 1 wherein the blade retention member comprises a pair of clips.

12. The shaving razor cartridge of claim 1 wherein the primary blade is a monolithic unitary member.

13. The shaving razor cartridge of claim 12 wherein at least one of the blade stabilizers is spaced more than 0.15 mm from the vertical base of the primary blade.

14. The shaving razor cartridge of claim 1 wherein each of the blade stabilizers has a respective top surface that declines in a direction toward a rear of the housing.

15. The shaving razor cartridge of claim 1 wherein an area between the cutting edge and the bent portion of the primary blade depresses into the respective blade stabilizers.
