Abstract

Abstract An apparatus including elongate handle formed with a hollow cavity directed interiorly of the lower end of the handle wherein the hollow cavity includes an internally threaded lower end cooperative with a threaded shaft of a plug member to selectively contain replacement blades within the cavity. The cutting head includes a reciprocatable cleaning plate mounted orthogonally relative to the elongate cutting edges of the spaced cutting blades slidably mounted within the head. Each of the blades includes an elongate cutting edge defined by alternating edge thicknesses to maintain structural integrity of the cutting edge while permitting an efficient and effective shaving operation.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 364 words
A safety razor apparatus comprising in combination, an elongate longitudinally aligned cylindrical handle formed with a cavity therewithin, the cavity formed within the lower-most end portion of the handle and wherein the cavity includes a lower-most internally threaded cavity end, and the internally threaded cavity end supportingly receives a plurality of replacement blades therewithin, and a plug means threadedly received within the cavity end to effect secured storage of the replacement blades within the cavity, and a shaving head orthogonally and integrally mounted to an upper terminal end of the handle, the shaving head including a plurality of spaced cutting blades slidably mounted therewithin, each cutting blade includes a cutting edge positioned forwardly through a forward end of the shaving head, and including a cleaning plate reciprocatably mounted within the shaving head positioned in contiguous relationship between the spaced cutting blades and reciprocatably mounted orthogonally relative to the cutting edges of the cutting blades, and wherein the cleaning plate is defined by a generally "T" shaped member with a forward semi-rigid cleaning head member mounted between the cleaning blades coextensively with the cutting edges for selective cleaning of the cutting between the cutting edges, and further including a rigid support head mounting the semi-rigid head member thereon, and elongate leg extending rearwardly of the support head and integrally mounted thereto this elongated leg projects rearwardly of the shaving head, and wherein the elongate leg includes a ribbed projecting tip projecting exteriorly of the shaving head to enhance manual grasping of the elongate leg for reciprocation of elongate leg relative to the cutting blades, and wherein each cutting edge of each cutting blade is defined by alternating segments of alternating thickness, and wherein the alternating segments include first wedge shaped thinned segments mounted between cutting edge portions of a predetermined thickness greater than a thickness defined by the thinned segments, and wherein each of the first wedge shaped thinned segments is defined by a triangular configuration including a base edge coextensive with the cutting edge, and each thinned segment defines a recessed area on each side surface of the segment between the cutting edge portions to accommodate pressure and debris encountered during a shaving procedure.
