A razor is provided, including a handle to be gripped by a user, a power generation unit disposed in the handle and configured to provide rotational power, a drive transmission unit coupled to the power generation unit and configured to be rotated by the rotational power, a cartridge including a blade housing on which one or more blades are seated, and a drive receiving unit formed at one side of the cartridge and configured to be in contact with the drive transmission unit to cause the blade housing to perform a linear movement in response to rotation of the drive transmission unit, wherein the cartridge is coupled to the handle such that the cartridge is pivotable about a pivot axis perpendicular to a rotational axis of the power generation unit, and wherein the pivot axis intersects the drive transmission unit.

A shaving aid for razor cartridges comprising water soluble filaments having nano-sized diameters and exhibiting lubricating properties and with improved visual and tactile aesthetics, wherein said nano-filament has a core and a sheath.

A shaving aid for razor cartridges comprising water soluble filaments having nano-sized diameters and exhibiting lubricating properties and with improved visual and tactile aesthetics.

A razor cartridge includes a plurality of razor blades installed in one direction of a cartridge frame, and a trimmer installed in the other direction of the cartridge frame, wherein the trimmer includes a trimming blade seated in a seating groove formed in the cartridge frame, and a trimmer cap coupled to both sides of the cartridge frame so that the trimming blade is fixed.

A shaving cartridge including a housing, a guard bar, a cap and cutting elements. The housing including an inner receiving portion and an inner attaching portion. The cutting elements further including a connecting structure at each end for connection of the cutting elements either on the housing or between adjacent cutting elements to thereby form a chain-like effect.

A shaving razor cartridge with a housing molded from a first polymeric material and having a top surface and an opposing bottom surface. The housing has a wall partially defining an opening extending from the top surface to the bottom surface. The wall has a pair of arms each with a distal end extending toward each other defining a gap. A guard is toward a front of the housing. A cap is toward a rear of the housing. At least one blade is mounted between the guard and the cap. A bridge interconnects the distal ends. The bridge is molded from a second polymeric material that is different than the first polymeric material.

Replaceable shaving assemblies are disclosed that include a razor cartridge comprising: an elongated housing defining a central open area, and, adjacent each short edge of the housing, a clip-receiving aperture and a clip-receiving channel; a plurality of blades disposed within the open area of the housing, and a pair of clips, each clip having a first leg and a second leg, the first leg extending through the clip-receiving aperture and being bent against a lower surface of the housing, and the second leg being wrapped around the housing and seated in the clip-receiving channel. Shaving systems including such shaving assemblies are also disclosed, as are methods of using such shaving systems and methods of manufacturing these cartridges.

The present invention relates to a razor including a handle, a frame coupled to the handle, a spacer, a top cap, a first blade secured between the frame and the spacer, and a second blade secured between the spacer and the top cap, wherein the first blade is supported by a portion of a top surface of the frame and a portion of a bottom surface of the spacer such that a first profile of the first blade is convexly curved upward, and wherein the second blade is supported by a portion of a top surface of the spacer and a portion of a bottom surface of the top cap such that a second profile of the second blade comprises a curved central region that is convexly curved upward and a pair of curved side regions that are concavely curved downward on opposite sides of the central region.

A method of resetting a digital counter for a personal care appliance by sending an electrical output signal from an optical sensor to a control circuit. The electrical output signal is compared to a predetermined value with the control circuit or a change in the electrical output signal from the optical sensor is detected over time. A signal is sent to a consumer user interface by the control circuit based on the electrical output signal and the predetermined value or based on the change in the electrical output signal from the optical sensor. The digital counter is reset based on an input signal from the consumer user interface.

A razor head, comprising a housing comprising one or more cutting elements, the housing further comprising a first window, and a second window; a substrate-based shaving aid delivery system, comprising a first reel that is rotatably mounted about a shaft, an actuator operationally coupled with the shaft, wherein at least part of the actuator protrudes externally from the housing via the first window; and a substrate carrying a shaving aid on its external surface.
