Abstract

A shaving blade unit with a housing having a bottom surface and a top surface defining a pair of elongated spaced apart apertures extending from the top surface to the bottom surface. At least one blade is mounted to the housing. The blade has a blade edge extending generally parallel to the pair of apertures. A solid polymeric lubrication member having an upper skin contact surface and an opposing base. A pair protrusions extend from the base. Each protrusion has an enlarged distal end. The enlarged distal ends of the protrusions each have a dimension greater than a dimension of the corresponding aperture whereby inserting the protrusion into the corresponding aperture deflects a front wall of the housing and each of the enlarged distal ends engage the bottom surface of the housing. The solid polymeric lubrication member and the enlarged distal ends are molded from a water soluble polymer.

First claim

What is claimed is:

1. A shaving blade unit comprising:
a housing having a bottom surface and a top surface, the housing having a guard and a cap;
at least one blade mounted to the housing between the guard and the cap;
a solid polymeric lubrication member comprising a water soluble polymer in front of the blades, the solid polymeric lubrication member having an upper skin contact surface;
an elastomeric member having a plurality of fins between the at least one blade and the solid polymeric lubrication member, wherein the upper skin contact surface of the solid polymeric lubrication member has an elongated portion in front of the fins and a pair of lateral ends that extend from the elongated portion toward the at least one blade; and
a pair of clips securing the at least one blade to the housing wherein the pair of lateral ends of the solid polymeric lubrication member are positioned directly in front of and immediately adjacent to the respective clips.

2. The shaving blade unit of claim 1 wherein the fins are positioned between the pair of lateral ends of the solid polymeric lubrication member.

3. The shaving blade unit of claim 1 wherein the clips are axially aligned with the pair of lateral ends of the solid polymeric lubrication member.

4. The shaving blade unit of claim 1 wherein the clip is spaced apart from the pair of lateral ends of solid polymeric lubrication member.

5. The shaving blade unit of claim 1 wherein the clip is metallic.

6. The shaving blade unit of claim 1 wherein the fins extend parallel to the at least one blade.

7. The shaving blade unit of claim 1 wherein the guard is spaced apart from the solid polymeric lubrication member defining an elongated gap.
