Abstract

A handle for a razor cartridge is provided. The handle includes 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 wherein the body comprises a first shell and a second shell that are releasably coupled together. A cover layer formed of a second material at least partially overlies the body and surrounds entirely at least a portion of the body. The cover layer has a base surface having a plurality of projections extending therefrom. Each projection of the plurality of projections is interposed between a pair of immediately adjacent projections. Each projection defines a height where the height of each projection is greater than the height of one of the immediately adjacent projections and less than the height of the other immediately adjacent projection.

Claims (29)

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 wherein the body comprises a first shell and a second shell that are releasably coupled together;

a cover layer at least partially overlying the body and surrounding entirely at least a portion of 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 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; and wherein:

the centerline is perpendicular to a first imaginary plane;

each projection of the plurality of projections and pairs of immediately adjacent projections are intersected by the first imaginary plane;

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.

2. The handle of claim 1 , wherein:

the centerline resides in the first imaginary plane.

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

4. The handle of claim 1 , 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.

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

6. The handle of claim 5 , wherein the second material has a hardness value of between 15 and 20 Shore A.

7. 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.

8. The handle of claim 7 , wherein the rod comprises one or more of steel, stainless steel and aluminum.

9. The handle of claim 7 further comprising a clip member coupled with the rear end of the body, wherein the rod is spaced from the clip member.

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

11. The handle of claim 10 , wherein the second material is less opaque than the first material.
