A shaving demonstration method having a step of providing a first shaving razor with a shaving surface having at least one blade with a cutting edge. A transparent first surface is provided. The shaving surface the first shaving razor contacts the transparent first surface. Another step includes illustrating the shaving surface of the first shaving razor against the transparent first surface through a transparent second surface opposite the first surface. The first shaving razor is moved along the transparent first surface.

A razor comprises a cartridge comprising a blade, the cartridge configured to rotate about a first axis, and a handle coupled to the cartridge. The handle comprises a first end, a second end opposite the first end, and a rotatable portion coupled to the second end such that the rotatable portion is configured to rotate relative to the first end and about a second axis. The rotatable portion comprises a base and a retention system. The retention system is configured to apply a resistance torque upon the rotatable portion when the rotatable portion is rotated from an at rest position.

A shaving razor that improves stability, corresponding user control and offers a closer shave is provided. The shaving razor can include a razor handle configuration that reduces the propensity for the shaving razor to roll in a users hand and improves the maneuverability of the razor cartridge during shaving. In addition, the shaving razor can include a biasing pivoting member producing a progressively increasing return torque on the razor cartridge that forces the cartridge into flat contact with the skin thus improving glide and shaving closeness.

An apparatus for demonstrating at least a first shaving razor, having a first shaving surface with a first lubrication member, may include a first sheet of paper, a liquid composition, and a light source transmitting ultraviolet light onto the first sheet of paper. The liquid composition may include water and an ultraviolet dye. The apparatus may position the shaving razor to engage the first sheet of paper and to allow relative motion between the first lubrication member and the first sheet of paper such that the first lubrication member deposits the liquid composition onto the first sheet of paper.

An apparatus for testing a razor blade comprises a base, a material support table, a material sample, a transport carriage, a blade retention assembly, and a razor blade. The material support table is supported by the base. The transport carriage is movably coupled with the base and is movable with respect to the material support table between a start position and an end position. The blade retention assembly is movably coupled with the transport carriage and is movable with respect to the material support table between a blade-engaged position and a blade disengaged position. The blade retention assembly is movable together with the transport carriage between the start position and the end position. The blade is releasably attached to the blade retention assembly. The razor blade contacts the material sample when the blade retention assembly is in the blade-engaged position. Methods are also provided.

The invention features a method for determining the worn shape of a deformable body in sliding contact with a deformable substrate. A wear depth w in an inward normal direction is determined at select points on a surface of the deformable body at each point in time t by integration of the following equation: dw d τ = kT n v b where k is a material dependent variable determined by physical tests, Tn is a contact pressure determined by finite element analysis of the deformable body in sliding contact with the deformable substrate at each point in time t, v is a constant sliding velocity between the deformable body and the deformable substrate, b is a constant determined by physical tests, and τ=tb is a computational time.

摘要:
A shaving demonstration apparatus having a rotatable support surface. A drive unit is operatively connected to the rotatable support surface. A fixture is spaced apart from the rotatable support surface. A first shaving razor has a first handle having a central longitudinal axis, said handle mounted to the fixture. A first blade cartridge unit is mounted to an end of the first handle, and rotates about a torsional rotation axis with respect to said handle, wherein the central longitudinal axis and the torsional rotational axis are generally parallel. The first blade cartridge unit contacts the rotatable support surface.
