Razor handles with integrated spring elements and/or methods of fabricating the same. In one example, a handle for a razor can comprise a head portion and a spring element having a distal end and a proximal end that longitudinally opposes the distal end to define an arc length of the spring element. The head portion can facilitate coupling razor cartridges in pivotal relation with the handle. The spring element can extend integrally from the head portion at the proximal end. The spring element can deflect as an abutment surface on the distal end travels in sliding engagement with a cam surface of a razor cartridge to an end point of the cam surface while exerting progressively increasing return torque as the razor cartridge rotates about a front pivot axis from a neutral position. The end point can fall proximal to a rear edge of the razor cartridge.

Shaving razor cartridge

Razor

A shaving razor cartridge includes a housing and at least one razor blade. The housing extends between a front end and a rear end. The housing includes a blade support portion and a handle interface portion. The blade support portion is positioned between the front end and the rear end and includes a cap and a guard. The guard is spaced from the cap and cooperates with the cap to define a shaving plane. The handle interface portion is positioned between the front end and the rear end and includes a rear wall, a front wall, a first sidewall, and a second sidewall. The rear wall includes a lower surface and an interior surface. The front wall includes a lower surface and an interior surface and is spaced from the rear wall. The at least one razor blade is disposed in the blade support portion.

A shaving razor cartridge includes a housing and at least one razor blade. The housing extends between a front and rear end and defines an overall width. The housing includes a blade support portion and a housing portion. The blade support portion is positioned between the front and rear ends and includes a cap and a guard spaced from the cap. The handle interface portion is positioned between the front and rear ends and includes a front and rear wall. The front wall includes lower and interior surfaces. The rear wall includes a lower surface, a central portion, a first distal portion, and a second distal portion. The central, first distal and second portions each include respective interior surfaces. The at least one razor blade is disposed in the blade support portion. Each of the first distal portion and the second distal portion extends from the central portion.

The invention provides a razor cartridge with multiple blades and peg(s) or pegged support members that aid in the control of the blades by restricting fore and aft blade movement, which in turn, reduces the amplitude of blade deflection and/or vibration during shaving. This reduction provided by the pegs improves shaving performance. Blades rest between pegs which are rounded or shaped such that the blade bottom portion contacts the peg at one point, forming a single line of contact. The pegs may be in a slalom-like, linear (with one or more peg columns), or offset arrangement. Pegs or pegged support members may be at any location of the razor blade assembly; for instance, at the center and/or at blade slot ends. Pegs may each be of different shapes and may or may not be equidistant or at the same heights as each other, depending on blade spans and exposures.
