Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
347 words
A substantially cylindrical pocket razor having: a substantially cylindrical body shaft having an upper portion and a lower portion, wherein the upper portion includes a slanted segment which is not parallel to the lower portion and front and back segments which are substantially parallel to the lower portion, the lower portion is substantially parallel to the shaft axis, the front segment of the shaft has a reduced diameter, the back segment has an interior chamber for containing shaving gel, and the slanted or front segment has one or more openings for removing the gel from the chamber; a razor blade base pivotably or removably attached to the front segment of the body shaft with a connector, the base having a razor blade; a substantially cylindrical plunger communicating with the body shaft, the plunger having an upper portion and a lower portion, wherein the upper portion includes a slanted segment which is not parallel to the lower portion and front and back segments which are substantially parallel to the lower portion, the lower portion is substantially parallel to the plunger axis which is substantially parallel to the shaft axis, wherein a major portion of the plunger has a diameter smaller than the inside diameter of the shaft, and wherein the communication is such that the plunger is slidable within the shaft; a substantially cylindrical plunger end cap having a closed end and an open end, the plunger cap having a diameter greater than either the plunger or the shaft, wherein the plunger cap interior surface communicates with the shaft outside surface and is capable of sliding along the shaft axis, and wherein plunger cap interior surface projections communicate with the plunger and transfer force which is administered to the plunger cap in the direction of the shaft front segment, to the plunger; and a substantially cylindrical shaft end cap having a closed end and an open end, the shaft cap having a diameter greater than the shaft, wherein the shaft cap interior surface communicates with the shaft outside surface and is capable of sliding along the shaft axis.
Claim 2
Dependent Claim

A substantially cylindrical pocket razor having: a substantially cylindrical body shaft having an upper portion and a lower portion, wherein the upper portion includes a slanted segment which is not parallel to the lower portion and front and back segments which are substantially parallel to the lower portion, the lower portion is substantially parallel to the shaft axis, the front segment of the shaft has a reduced diameter, the back segment has an interior chamber for containing shaving gel, and the slanted or front segment has one or more openings for removing the gel from the chamber; a razor blade base pivotably or removably attached to the front segment of the body shaft with a connector, the base having a razor blade; a substantially cylindrical plunger communicating with the body shaft, the plunger having an upper portion and a lower portion, wherein the upper portion includes a slanted segment which is not parallel to the lower portion and front and back segments which are substantially parallel to the lower portion, the lower portion is substantially parallel to the plunger axis which is substantially parallel to the shaft axis, wherein a major portion of the plunger has a diameter smaller than the inside diameter of the shaft, and wherein the communication is such that the plunger is slidable within the shaft; a substantially cylindrical plunger end cap having a closed end and an open end, the plunger cap having a diameter greater than either the plunger or the shaft, wherein the plunger cap interior surface communicates with the shaft outside surface and is capable of sliding along the shaft axis, and wherein plunger cap interior surface projections communicate with the plunger and transfer force which is administered to the plunger cap in the direction of the shaft front segment, to the plunger; and a substantially cylindrical shaft end cap having a closed end and an open end, the shaft cap having a diameter greater than the shaft, wherein the shaft cap interior surface communicates with the shaft outside surface and is capable of sliding along the shaft axis.
Claim 3
Dependent Claim
53 words
A razor according to claim 1 wherein the razor blade base is coupled to a bracket which is mounted to the shaft front segment, such that the razor blade base may be selectively positioned in a position substantially parallel to the shaft axis, or in a position substantially perpendicular to the shaft axis.
