Abstract

A razor that facilitates a user's removal of shaving lubricant, cut hairs, and other shaving-related debris, from around, and between, the razor's blade(s). A scoop at the upper portion of the razor's blade assembly funnels water to the blade channel in which the blades are affixed, and at least a portion of that water flows around and/or over the blade(s). The scoop captures, and directs through the razor's blades, a greater volume of water per unit time than can be achieved with an unmodified blade assembly. The cross-sectional area of the scoop's inflow mouth is greater than that of the blade channel's outflow mouth, thereby promoting a Venturi effect which increases the speed of the water's flow over the blades.

Claims (7)

1. A razor blade cartridge, comprising:

an open razor blade housing having, a mouth defined by first and second triangular side walls, a back wall portion, and a base portion, inner surfaces of said sidewalls, said back wall portion, and said base portion cooperating to define a concave scoop, said base portion including a drain substantially centered along said base portion and spaced from front and rear edges of said base portion; and

a plurality of razor blades fixed inside said drain;

wherein the inner surface of the back wall portion has an increasing curve from a tip of said back wall portion to said drain; and

wherein said plurality of blades are all angled parallelly toward said back wall portion.

2. The razor blade cartridge of claim 1 , further comprising a handle.

3. The razor blade cartridge of claim 2 , wherein an angle formed by a plane defined by an outer surface of said triangular side walls that define an opening at said mouth and a plane defined by said inner surface of said base portion defining an opening in said drain is less than ninety degrees.
