Shaving razor cartridge

1. A shaving razor cartridge comprising:

a housing that extends between a front end and a rear end, the housing comprising:

a blade support portion positioned between the front end and the rear end and comprising:

a cap; and

a guard spaced from the cap and cooperating with the cap to define a shaving plane; and

a handle interface portion positioned between the front end and the rear end and comprising:

a front wall comprising a lower surface and an interior surface;

a rear wall comprising a lower surface and an interior surface, the front wall and the rear wall being spaced from each other such that the interior surfaces cooperate to at least partially define a handle receptacle;

an upper surface that defines an upper opening; and

a locking member extending from the interior surface of the rear wall towards the front wall, the locking member configured to facilitate selective retention of a razor handle to the housing; and

at least one razor blade disposed in the blade support portion between the cap and the guard, wherein:

the lower surfaces cooperate to define a lower opening;

the handle receptacle extends between the lower opening and the upper opening;

the locking member overhangs the rear wall and extends into the handle receptacle; and

the upper opening is more proximate to the shaving plane than the lower opening.

2. The shaving razor cartridge of claim 1 wherein the locking member extends from the rear wall at a vertical distance that is between about 1 mm and about 3 mm.

5. The shaving razor cartridge of claim 4 wherein:

the deflection member comprises a pair of distal members and central portion that is interposed between the pair of distal members;

the at least one support arm comprises a pair of support arms;

the distal members are coupled with respective ones of the support arms; and

the central portion is more proximate the front wall than the distal members.

6. The shaving razor cartridge of claim 5 wherein the deflection member comprises an upper surface and the lower surface of the rear wall and the upper surface of the deflection member are spaced from each other and cooperate to define a slot therebetween.

7. The shaving razor cartridge of claim 6 wherein the upper surface of the deflection member and the interior surface of the rear wall are angled with respect to each other by less than 90 degrees.

8. The shaving razor cartridge of claim 7 wherein the upper surface of the deflection member and the interior surface of the rear wall are angled with respect to each other by about 80 degrees.

9. The shaving razor cartridge of claim 4 wherein:

the interior surface of the rear wall is substantially planar and defines a rear plane that intersects the locking member; and

the deflection member is interposed between the rear plane and the front wall.

10. The shaving razor cartridge of claim 1 wherein the front wall has a first height, the rear wall has a second height and the first height is less than the second height.

11. The shaving razor cartridge of claim 10 wherein:

the at least one razor blade extends laterally between opposing sides of the blade support portion;

the lower opening has a first length that extends laterally along the handle interface portion;

the upper opening has a second length that extends laterally along the handle interface portion; and

the first length is greater than the second length.

12. The shaving razor cartridge of claim 1 wherein the upper surface is within a vertical distance of the shaving plane.

13. The shaving razor cartridge of claim 12 wherein the upper surface is disposed between the shaving plane and the lower surfaces.

14. The shaving razor cartridge of claim 13 wherein the vertical distance is less than 1 mm.

15. A shaving razor cartridge comprising:

a housing that extends between a front end and a rear end, the housing comprising:

a blade support portion positioned between the front end and the rear end and comprising:

a cap; and

a guard spaced from the cap and cooperating with the cap to define a shaving plane; and

a handle interface portion positioned between the front end and the rear end and comprising:

a front wall comprising a lower surface and an interior surface;

a rear wall comprising a lower surface and an interior surface, the front wall and the rear wall being spaced from each other such that the interior surfaces cooperate to at least partially define a handle receptacle;

an upper surface that defines an upper opening; and

a locking member extending from the interior surface of the rear wall towards the front wall, the locking member configured to facilitate selective retention of a razor handle to the housing; and

at least one razor blade disposed in the blade support portion between the cap and the guard, wherein:

the lower surfaces cooperate to define a lower opening;

the handle receptacle extends between the lower opening and the upper opening;

the upper opening is more proximate to the shaving plane than the lower opening;

the locking member comprises a deflection member and a pair of support arms that overhang the rear wall and extend into the handle receptacle;

each support arm of the pair of support arms is coupled with the rear wall and extends from the rear wall;

the deflection member comprises a pair of distal members and central portion that is interposed between the pair of distal members;

the distal members are coupled with respective ones of the support arms; and

the central portion is more proximate the front wall than the distal members.

16. The shaving razor cartridge of claim 15 wherein the deflection member comprises an upper surface and the lower surface of the rear wall and the upper surface of the deflection member are spaced from each other and cooperate to define a slot therebetween.

17. The shaving razor cartridge of claim 15 wherein the upper surface of the deflection member and the interior surface of the rear wall are angled with respect to each other by less than 90 degrees.

18. The shaving razor cartridge of claim 17 wherein the upper surface of the deflection member and the interior surface of the rear wall are angled with respect to each other by about 80 degrees.
