Abstract

A novel handle for a razor cartridge is provided. The handle comprises a head having a cartridge engaging end and an attachment end, a body formed of a first material and defining a centerline, the body having a front end and a rear end, wherein the front end is coupled with the attachment end. A cover layer at least partially overlies the body and is formed of a second material. The cover layer comprises a base surface having a plurality of projections extending therefrom, wherein each projection of the plurality of projections has an upper surface that is substantially planar.

Claims (38)

1. A handle for a razor cartridge, the handle comprising:

a head having a cartridge engaging end and an attachment end;

a body formed of a first material and defining a centerline, the body having a front end and a rear end, wherein the front end is coupled with the attachment end; and

a cover layer at least partially overlying the body and formed of a second material, the cover layer comprising a base surface having a plurality of projections extending therefrom, wherein each projection of the plurality of projections has an upper surface that is substantially planar, wherein:

each projection of the plurality of projections is interposed between a pair of immediately adjacent projections;

each projection of the plurality of projections defines a height; and

the height of each projection of the plurality of projections is:

greater than the height of one of the immediately adjacent projections; and

less than the height of the other immediately adjacent projection.

2. The handle of claim 1 , wherein:

the centerline resides in a first imaginary plane;

each projection of the plurality of projections and pair of immediately adjacent projections is intersected by the first imaginary plane; and

the height of each projection of the plurality of projections is:

greater than the height of one of the immediately adjacent projections along the first imaginary plane; and

less than the height of the other immediately adjacent projection along the first imaginary plane.

3. The handle of claim 1 , wherein:

the centerline is perpendicular to a second imaginary plane;

each projection of the plurality of projections and pair of immediately adjacent projections is intersected by the second imaginary plane; and

the height of each projection of the plurality of projections is:

greater than the height of one of the immediately adjacent projections along the second imaginary plane; and

less than the height of the other immediately adjacent projection along the second imaginary plane.

4. The handle of claim 1 , wherein each projection of the plurality of projections is frusto-pyramidal shaped.

5. The handle of claim 1 , wherein the body comprises a first shell and a second shell that are releasably coupled together.

6. The handle of claim 5 , wherein:

the first shell and the second shell each define one or more through holes; and

the cover layer extends into each of the through holes.

7. The handle of claim 1 , wherein the second material comprises thermoplastic elastomer.

8. The handle of claim 7 , wherein the second material has a durometer value of between about 15 and about 20.

9. The handle of claim 1 further comprising a rod, wherein:

the body defines a hollow interior;

the rod is disposed in the hollow interior of the body; and

the centerline extends through the rod.

10. The handle of claim 9 , wherein the rod comprises one or more of steel, stainless steel and aluminum.

11. The handle of claim 9 further comprising a clip member coupled with the rear end of the body, wherein the rod is spaced from the clip member.

12. The handle of claim 1 , wherein the cover layer entirely circumferentially surrounds at least a portion of the body.

13. The handle of claim 1 , wherein the second material is substantially translucent.

14. The handle of claim 13 , wherein the second material is less opaque than the first material.

15. The handle of claim 1 , wherein each projection of the plurality of projections has an upper surface that resides in an imaginary plane that is substantially perpendicular to a radial line extending from the centerline.
