Abstract
Abstract A shaving system in the nature of a kit comprises a single elongated handle and a pair of disposable blade assemblies, one blade assembly carrying a single edge blade and the other blade assembly carrying a pair of closely spaced twin blades. The handle end and each blade assembly are formed with coacting twist-lock fittings so that first the single edge blade assembly and then the double edge blade assembly can be detachably connected to the handle so that the user can shave with both blade assemblies in sequence to obtain an unusually close shave. The kit also includes a covered caddy for receiving and retaining the handle and two blade assemblies when they are not in use.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
130 words
A shaving kit comprising an elongated handle, a pair of blade assemblies to be used in sequence, each assembly having an elongated neck and a head formed integrally with the neck, a single edge blade mounted in one shaving assembly head, a pair of closely spaced, parallel blades mounted in the other shaving assembly head, coacting means on an end of the handle and on the free end of the neck of each blade assembly for detachably connecting the neck to the handle, and a caddy for removably retaining the handle and the two blade assemblies, said caddy comprising a container having three receptacles, one receptacle sized to receive and retain an end of the handle and the other two receptacles sized to receive and retain the two blade assemblies.
Claim 2
Dependent Claim
130 words
A shaving kit comprising an elongated handle, a pair of blade assemblies to be used in sequence, each assembly having an elongated neck and a head formed integrally with the neck, a single edge blade mounted in one shaving assembly head, a pair of closely spaced, parallel blades mounted in the other shaving assembly head, coacting means on an end of the handle and on the free end of the neck of each blade assembly for detachably connecting the neck to the handle, and a caddy for removably retaining the handle and the two blade assemblies, said caddy comprising a container having three receptacles, one receptacle sized to receive and retain an end of the handle and the other two receptacles sized to receive and retain the two blade assemblies.
Claim 3
Dependent Claim
29 words
The kit defined in claim 1 and further including a protective cover for engaging over the handle and blade assemblies retained in the caddy and seating on the caddy.
Claim 4
Dependent Claim
45 words
The kit defined in claim 1 wherein the connecting means comprise a twist-lock connector, one component of the connector being mounted to the end of the handle and the other component of the connector being formed at the free end of each blade assembly neck.
Claim 5
Dependent Claim
153 words
The kit defined in claim 3 wherein the connector component on the handle comprises a cylindrical neck projecting from the end of the handle and a larger diameter semicylindrical lug formed on the free end of the neck with the centers of the neck and the lug coinciding, and the connector component on each shaving assembly neck comprises a semicylindrical passage extending into the free end of the neck, the diameter of the passage being more or less the same as that of the lug, a quadrant passage formed at the bottom of the semicylindrical passage, said quadrant passage being coaxial with and having the same radius as that of the semicylindrical passage so that the lug can be inserted into the longitudinal passage and turned at right angles about its axis so that an end of the lug extends into the quadrant passage thereby locking the blade assembly neck to the handle.
Claim 6
Dependent Claim
79 words
The kit defined in claim 4 wherein each blade assembly neck extends at right angles relative to the associated blade assembly head, with the segment of each neck containing the passages being oriented at an obtuse angle relative to the remainder of the neck so that, when the handle is grasped by the user while shaving, the blade mounted to the head of each blade assembly is oriented at the proper shaving angle relative to the surface being shaved.
Claim 7
Dependent Claim
57 words
A shaving method comprising the steps of washing the face; applying a thin layer of facial cream to the face; applying lather to the face over the cream layer; shaving the face with a single edge hollow ground razor; rinsing the face free of all shaving materials and shaving again with a twin type feather edge razor.
