Abstract
Abstract An improved shaver includes a plate having a substantially flat spreading surface for spreading shaving cream or gel onto an area to be shaved to form a thin substantially uniform layer of shaving cream or gel. The substantially flat spreading surface is preferably as wide as the shaving head and long enough to avoid the shaving cream foam flowing over the bottom of the plate. The shaver preferably includes a chamber for storing the shaving cream and a mechanism for dispensing it onto the substantially flat spreading surface at a preselected rate. The substantially flat surface can include flat parallel projections that are spaced apart from each other. These projections facilitate spreading of the cream or gel. The substantially flat spreading surface can be subdivided into a plurality of articulated panels which can be folded over the shaving head to protect the razor blade.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
169 words
A shaver capable of dispensing and spreading shaving cream onto an area to be shaved, said shaver comprising: a shaving head having a first portion for holding at least one razor blade and a second portion opposite to said first portion; an elongated handle attached to the second portion of said shaving head; a chamber inside said handle for holding pressurized shaving cream; a plate having a substantially flat spreading surface, said plate attached to said handle and to the second portion of said shaving head, said substantially flat surface being generally perpendicular to the plane of the razor blade and having at least one opening therein; an actuator for selectively opening and closing communication between said chamber and said opening so that when the communication is open the shaving cream flows from said chamber through said opening onto said substantially flat spreading surface so as to allow said shaving cream to be distributed into a thin uniform layer onto the shaved area using said substantially flat spreading surface.
Claim 2
Dependent Claim
169 words
A shaver capable of dispensing and spreading shaving cream onto an area to be shaved, said shaver comprising: a shaving head having a first portion for holding at least one razor blade and a second portion opposite to said first portion; an elongated handle attached to the second portion of said shaving head; a chamber inside said handle for holding pressurized shaving cream; a plate having a substantially flat spreading surface, said plate attached to said handle and to the second portion of said shaving head, said substantially flat surface being generally perpendicular to the plane of the razor blade and having at least one opening therein; an actuator for selectively opening and closing communication between said chamber and said opening so that when the communication is open the shaving cream flows from said chamber through said opening onto said substantially flat spreading surface so as to allow said shaving cream to be distributed into a thin uniform layer onto the shaved area using said substantially flat spreading surface.
