A razor cartridge has an elongated housing with a guard having spaced-apart ribs; a cap at a respective front and rear region of the housing; and a partition extending between and integrally formed with opposed lateral side walls of the housing. A first razor blade is mounted in a first blade mounting region between the guard and the partition. A second razor blade adjacent the partition, and a third razor blade are mounted in a second blade mounting region between the partition and the cap. A first span between the cutting edge of the first razor blade and the cutting edge of the second razor blade is at least 3.0 mm up to 5.12 mm. Pivotal connecting structure of the housing defines a pivot axis in a region between the cutting edges of the first and second razor blades.

One or more implementation disclosed herein provides razor assemblies that allow a user to have a less than smooth shave by changing the distance between razor blades and a razor blade guard. The distance between the razor blade(s) and the guard may be increased or decreased using a movable knob mechanism, a rotatable dial mechanism, a movable razor assembly and housing mechanism, a rotatable threaded handle, one or more slider mechanisms, a rotating blade mechanism, etc.

A razor blade including a blade body, an expanded coating structure arranged on a surface of the blade body so as to cover the blade body at least partially, the expanded coating structure including one or more expanded polymer microspheres, at least one of the one or more expanded polymer microspheres including a gas encapsulated within a hollow thermoplastic polymer shell. A process for fabrication of same, including providing a blade body, depositing a liquid suspension, the liquid suspension including expandable polymer microspheres dispersed in a liquid uncured polymer precursor, each expandable polymer microsphere including a gas encapsulated within a hollow thermoplastic polymer shell, on a surface of the blade body to obtain a deposit, and expanding at least a portion of the expandable polymer microspheres in the deposit to obtain an expanded deposit including one or more expanded polymer microspheres arranged on the surface of the blade body, the liquid uncured polymer precursor being configured to remain uncured during expansion of the expandable polymer microspheres. A skincare device including such a razor blade. A process of fabricating same, including attaching such a razor blade to a cartridge.

A razor cartridge comprising three or more substantially parallel cutting members disposed between a leading longitudinal side and a trailing longitudinal side of the razor cartridge in a shaving direction of the razor cartridge. Each of the cutting members comprises a blade support comprising a blade mounting portion disposed on an inner surface of the respective blade support that, in use, faces away from a shaving plane, and a blade attached to the blade mounting portion. The cutting members are disposed to define a plurality of inter-blade spans between cutting edges of the blades. A leading inter-blade span that is closer to the leading longitudinal side of the razor cartridge than a trailing inter-blade span is different to the trailing inter-blade span that is closer to the trailing longitudinal side of the razor cartridge than the leading inter-blade span.

A blade assembly including at least one blade support and at least one blade element having a cutting edge portion. The blade support includes a base portion and a flat portion. The flat portion extends at an angle with respect to the base. The at least one blade is attached to the flat portion of the blade support. The blade assembly further includes a lubricating element. The lubricating element is attached to the flat portion and the at least one blade element.

A cutting member (1) for a shaving cartridge includes a front side, a back side opposing the front side, and a flat cutting portion (2) with a cutting edge portion (4). Further the cutting member includes a first bent portion (8), an intermediate portion (11), a second bent portion (9) and a base portion (10) that are made out of one single piece of material. The first bent portion is integral with the flat cutting portion. The first bent portion is convex on the back side of the cutting member, and the second bent portion is concave on the back side of the cutting member. The proposed shape of the cutting member resembles an “S” shape or a question mark shape.

An intelligent shaving system includes a handle, at least one blade connected to the handle, a microcontroller attached to the handle, a wireless communication unit configured to send and receive data from microcontroller to an external device, a memory configured to store data applicable to the at least one blade, and one or more sensors configured to send sensory data from the one or more sensors to microcontroller. The one of the one or more sensors is a proximity sensor or a camera having image sensor configured to capture video and/or still images. The shaving system assists in determining blade attrition and provides indicators to assist in shaving techniques. The shaving system further may include at least one blade slightly curved to follow a tangent of the skin. The at least one blade may have a nanolattice structure.

A flexible razor assembly for shaving contours on a user's body includes a handle that has a blade channel integrated therein. A lever is pivotally coupled to the handle and a blade case is coupled to the lever. The blade case is positionable in an open position and a closed position and the blade case is bendable to conform to curvature of a user's body. A blade is provided and the blade is comprised of a bendable material. The blade is positionable in the blade case having a cutting edge of the blade being exposed for shaving the user's body.

A razor cartridge is proposed. The razor cartridge may include at least one blade having an edge portion and a cutting edge formed at the tip of the edge portion. The at least one blade may include a substrate comprising a substrate tip and a coating layer formed on the substrate to form the cutting edge. The coating layer may include a first facet extending toward one side from a final edge forming a tip of the cutting edge, to face a skin surface during shaving and a second facet extending toward the other side from the final edge to opposite to the first facet. A blade angle between the skin surface and a line passing through a bisector of the edge portion may be greater than an efficient angle between the skin surface and a line passing through a bisector of the final tip.

A razor cartridge is proposed. The razor cartridge may include at least one blade having a cutting edge. The blade may include a substrate including a substrate tip, and a coating layer formed on the substrate to form the cutting edge. The coating layer may include a first facet extending toward one side from a final tip forming a tip of the cutting edge, a second facet extending toward the other side from the final tip, a third facet extending from the first facet, and a fourth facet extending from the second facet. A distance between a second wedge formed at a boundary between the second facet and the fourth facet and a dividing line dividing the final tip may be longer or shorter with a deviation 20% as compared to a distance between a first wedge formed at a boundary between the first facet and the third facet and the dividing line.
