A razor cartridge is disclosed herein. An embodiment of the present disclosure provides a razor cartridge configured to be coupled to a razor handle and used, the razor cartridge including: at least one shaving blade having a cutting edge; a blade housing configured to accommodate the at least one shaving blade so that the at least one shaving blade is placed in a longitudinal direction, the blade housing including a top side to which the cutting edge is directed and a bottom side facing the top side; a support structure coupled to one side of the blade housing; and at least one first living hinge configured to connect at least a portion of the blade housing to at least a portion of the support structure.

A shaving head that doubles as breaking mechanism to break a safety razor blade into two pieces to form a 2-blade shaving razor. The shaving head includes a front component having a retention guide, a first position stop and a second position stop at a distance offset from the first position stop. The shaving head further includes a back component having a blade slot configured to receive a first blade portion and a second blade portion formed from breaking a double-edge safety razor blade such that the first blade portion has a different width compared to the second blade portion. The retention guide is configured to retain the first blade portion and the second blade portion in the blade slot responsive to the retention guide being at least partially inserted into the blade slot. The sharp shaving edges once installed form a shaving angle between 5 and 30 degrees, where the shaving angle is determined by where the blade is broken.

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.

A method of manufacturing a razor cartridge by molding a housing having a first mounting surface with a first notch extending into the housing to a first inner side wall. At least one blade is having a cutting edge is mounted to the housing. A first blade retention member is mounted over the cutting edge and on top of the first mounting surface. The first blade retention member is spaced apart from the first inner side wall by at least 0.25 mm.

A shaving blade cartridge including a housing having a top side, a bottom side and two longitudinal sides. A cutting element is mounted in the housing between the longitudinal sides, and is retained in the housing by a retainer. The retainer includes an internal surface which extends in a direction toward the cutting element. The internal surface is provided with a non-smooth pattern that cooperates with the cutting element. The shaving blade cartridge including the retainer having an internal surface provided with a non-smooth pattern is configured to be connected to a handle of a shaver.

A razor head that includes a housing having a top face defining a shaving window delimited by a front guard and a rear cap together defining a tangent plane, at least one rigid cutting member, each freely mounted in the housing, and having a cutting edge portion extending along a cutting edge portion axis, and having a cutting edge accessible through the shaving window, a guided portion extending along a guided portion axis, and a bent portion intermediate the cutting edge portion and the guided portion. An angle measured between the cutting edge axis and the tangent plane is between 5° and 30°.

A shaving razor having a cartridge containing a razor blade coupled to a monolithic yoke. The yoke is formed from a single piece of material possibly by injection molding. The yoke has a bridge and a pair of cross pieces each coupled to the bridge by a living hinge. The cartridge is coupled to the cross pieces and spans between the cross pieces.

A linkage for reciprocating razor. The linkage with flexible regions between the blade assembly attachment points. The linkages permitting reciprocating motion of the blade assemblies where adjacent assemblies reciprocate in opposite directions. Other embodiments are also described and claimed.

Embodiments of the invention include a blade unit (10) for a safety razor (8), comprising: a connecting structure (14) configured to fix the blade unit to a handle (16); a blade housing (12) comprising a plurality of blades (18) having respective cutting edges (20) lying in a shaving plane and being arranged to exert a cutting action when moved across a user's skin in a shaving direction; and a rear portion (24) arranged next to the plurality of blades in the shaving direction, comprising a non-flexible concave back portion (26) that arcuately bends away from the shaving plane, and a convex lubricating pad (22) arranged on and being supported by the non-flexible concave back portion and which extends up to a rear edge (28) of the rear portion of the blade unit.

A razor cartridge and a method of manufacturing the same are disclosed. The present disclosure in at least one embodiment provides a razor cartridge including one or more shaving blades each having a cutting edge, a blade housing configured to accommodate the one or more shaving blades in a longitudinal direction of the blade housing, and one or more clips each configured to fix the one or more shaving blades to the blade housing and having a shape of a closed loop.
