Abstract: A razor cartridge is provided that includes a frame, at least four razor blades, a guard that includes a contact surface, and a cap that includes a contact surface. The razor blades are supported by the frame. The guard is disposed forward of the razor blades and the cap is disposed aft of the razor blades. The razor blades are arranged so that the cutting edge of each razor blade is adjacent a plane that tangentially intersects the contact surfaces of the guard and the cap. As a result, each stroke of the razor exposes the surface being shaved to at least four razor blade cutting edges in succession. A unitary razor assembly that includes a head characterized in the same manner as the above-described cartridge is also provided.

Abstract: A razor blade and support assembly is provided which flexes in response to shaving forces near slots in the blade support. A razor cartridge includes one or more of the aforementioned razor blade and support assemblies positioned in a housing. The razor cartridge may be permanently or removably coupled to a handle to provide a shaving razor.

Abstract: A razor assembly is provided that includes a razor cartridge with one or more razor blades, a shaving aid body, a handle, and a linkage pivotally connected to the handle. The linkage is connected to the razor cartridge and the shaving aid body in a manner such that the razor cartridge and the shaving aid body are moveable relative to the handle. Movement of one of the razor cartridge or the shaving aid body in a first direction causes the other of the razor cartridge or the shaving aid body to move in a second direction substantially opposite the first direction. As a result, the positions of the shaving aid body and the razor cartridge are continuously adjusted to maintain the contact surface of the shaving aid body approximately co-planar with the cutting edges of the razor blades within the razor cartridge.

Abstract: An improved skin engaging device for use in razor cartridge assemblies and shaving systems of the wet shave type. In an embodiment, there is provided a two-component, control-release device having a sheath layer made from thermoplastic resins with openings in its skin engaging surface, coextruded with a core region containing shaving aids. At least one end of the device is at least partially closed to inhibit the ingress of water at that end of the device and to inhibit the release of the shaving aid from that end of the device during a normal shaving operation. Enclosure of the end of the device can be by addition of an end cap, by application of a film of a suitable sealant or by suitably joining opposed inner walls of a portion of the sheath extending beyond the core.

Abstract: The present invention is directed in one aspect to a razor cartridge having a shaving aid dispensing system that includes a housing that defines a cavity in which a supply of shaving aid film is disposed. At least one razor blade is positioned within the housing and has an at least partially exposed cutting edge. The supply of shaving aid film is positioned in the cavity and is used to transfer shaving aid to a user's skin during a shaving operation. An applicator is coupled to the housing adjacent the cutting edge of the razor blade. shaving aid film is drawn over the applicator in response to the razor cartridge being moved over, and in contact with, a user's skin during a shaving operation. The shaving aid film deposits at least a portion of the shaving aid provided onto the user's skin.

Abstract: In a shaving implement a handle is provided that includes a body section and an end portion projecting outwardly therefrom. An axle member is rotatably coupled to the end portion for selective angular movement relative thereto. A razor cartridge is coupled to the axle member and includes at least one razor blade that defines an at least partially exposed cutting edge. The razor cartridge is rotatably moveable with the axle member and the detent is provided for releasably retaining the axle member and thereby the razor cartridge in the user selected angular position relative to the handle.

Abstract: In a razor cartridge, a platform portion has a first cartridge section that includes at least one first pair of razor blades position therein. Each of the first pair or razor blades has an at least partially exposed cutting edge. A second cartridge section is also provided and is coupled to the platform portion. The second cartridge section includes at least one pair of second razor blades positioned therein, each of the second pair of razor blades also has an at least partially exposed cutting edge. The razor cartridge can be mounted either temporarily or permanently to a handle and the cutting edges of each of the first and second pair of razor blades face one another so that during a shaving operation, the razor cartridge can cut hair when drawn over a user's skin in either of two generally opposite directions.

Abstract: A blade cartridge for a wet shaving device comprises a housing defining a cavity in which at least two blade assemblies are disposed. Each blade assembly includes a plurality of blades defining respective cutting edges that are substantially parallel to each other and generally face the cutting edges of another blade assembly. The blades are mounted on a carrier, and a wire is spirally wound about the cutting edges of the blades along the length of the cutting edges.

Abstract: A method for manufacturing a razor blade. In the method, a razor blade blank is coined to produce a razor blade with a cutting edge. It is preferred that the razor blade blank be unhardened for coining. Additional manufacturing steps that may be performed are hardening of the razor blade at least in the vicinity of the cutting edge, and finishing the cutting edge. The method allows for the cost-effective manufacture of razor blades having both linear and non-linear cutting edges.

Abstract: In a razor cartridge, a housing is provided having first and second razor blade assemblies positioned therein. The first and second razor blade assemblies each include at least one razor blade and an at least partially exposed cutting edge. The razor blades are positioned in the first and second blade assemblies to allow hair to be cut from a user's skin when the razor cartridge is drawn thereover in either of two generally opposite cutting directions. At least one shaving aid outlet is defined by the razor cartridge and positioned between the first and second razor blade assemblies to allow the shaving aid to be dispensed therethrough.
