Abstract

Abstract A brush having bristles of varying heights in predetermined configurations is disclosed for extirpating ingrown facial hair from false follicles prior to shaving. The brush includes bristles of specified shapes, and incorporates a support for a razor. By properly preparing ingrown hairs for shaving a condition known as pseudofolliculitis barbae is more easily managed, thus alleviating physical and social discomfort.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 225 words
Facial scrubbing brush for removing ingrown hairs from false follicles, comprising: a base portion; peripheral side support means connected to said base portion; and a plurality of elongated discrete, resilient members connected to said base portion and disposed perpendicular thereto, including first members of a uniform height, each discrete first member being arranged exclusively in first concentric annular rows on said base portion such that said first concentric annular rows exclusively comprise said first members, and second members having a plurality of heights shorter than said uniform height, each discrete second member being arranged exclusively in second concentric annular rows on said base portion such that said second concentric annular rows exclusively comprise said second members, said first annular rows being separate and distinct from said second annular rows and at least one of said first annular rows being interspaced between a pair of said second annular rows, each of said discrete first members being sufficiently resilient and having a cross-sectional dimension sized to curl beneath and into loops of ingrown facial hair, and each of said discrete second members cooperating with said first members to dislodge said ingrown hairs as the brush is moved along the face, wherein said base portion is concave in a direction opposite to said elongated members and includes a plurality of first drainage means distributed about the periphery thereof.
Claim 2
Dependent Claim 225 words
Facial scrubbing brush for removing ingrown hairs from false follicles, comprising: a base portion; peripheral side support means connected to said base portion; and a plurality of elongated discrete, resilient members connected to said base portion and disposed perpendicular thereto, including first members of a uniform height, each discrete first member being arranged exclusively in first concentric annular rows on said base portion such that said first concentric annular rows exclusively comprise said first members, and second members having a plurality of heights shorter than said uniform height, each discrete second member being arranged exclusively in second concentric annular rows on said base portion such that said second concentric annular rows exclusively comprise said second members, said first annular rows being separate and distinct from said second annular rows and at least one of said first annular rows being interspaced between a pair of said second annular rows, each of said discrete first members being sufficiently resilient and having a cross-sectional dimension sized to curl beneath and into loops of ingrown facial hair, and each of said discrete second members cooperating with said first members to dislodge said ingrown hairs as the brush is moved along the face, wherein said base portion is concave in a direction opposite to said elongated members and includes a plurality of first drainage means distributed about the periphery thereof.

Dependent Claim 19 words
Facial scrubbing brush as recited in claim 1 further comprising means for storing a razor in said base portion.
Claim 6
Dependent Claim 44 words
Facial scrubbing brush as recited in claim 4 wherein said means for storing comprises means extending to a second predetermined distance beyond said base portion in a direction opposite to said elongated members, said second predetermined distance being smaller than said first predetermined distance.
Claim 7
Dependent Claim 27 words
Facial scrubbing brush as recited in claim 1 wherein said elongated members are sized and configured to engage loops of ingrown hairs in a plurality of directions.
Claim 8

Claim 9
Dependent Claim 50 words
Facial scrubbing brush as recited in claim 7 wherein said first elongated members terminal portions are sharpened at a first radius curvature and said second elongated members terminal portions are sharpened at a second radius of curvature, said first radius of curvature being greater than said second radius of curvature.
Claim 10
Dependent Claim 27 words
Facial scrubbing brush as recited in claim 1 wherein said first members are arranged in alternate annular rows, said second members being in the alternative annular rows.
