摘要： A razor cartridge has a housing with a blade mounting region between a guard and a cap. A first and a second razor blade are sequentially mounted in the blade mounting region with an intermediate non-cutting and skin engaging structure between the blades. The intermediate structure has a leading edge region closest the guard and at or adjacent a skin engaging surface of the intermediate structure. The leading edge region of the intermediate structure has an elastomeric linear seal contacting the first razor blade to seal any gap between the intermediate structure and the first blade.

摘要： A razor cartridge (10) includes a frame (12) and a razor blade (14). The frame includes a guard (46), a cap (52), an opening configured to receive a razor blade (14), and a blade-receiving slot (40). The blade-receiving slot includes a front support (56) and a rear support (58). The front support includes a front side surface (64) and a front blade locating surface (60). The rear support includes a rear side surface (66) and a rear blade locating surface (62). The front side surface and the rear side surface are coplanar. The front blade locating surface and the rear blade locating surface extend from the coplanar side surfaces in generally opposite directions. The razor blade includes an edge portion (22) and a support portion (20) that are bent at an angle relative to one another. The support portion of the razor blade is positioned in the slot. A clip (26) may be utilized to retain the razor blade in the slot.

摘要： A razor cartridge (20) has a housing (30) with a blade mounting region (70) between a guard (40) and a cap (50). A first, second and third razor blade (80, 90, 100) are sequentially mounted in the blade mounting region. An over-guard (120) is secured over the blades. The cutting edges (82, 92, 102) of the blades have an as-defined increased sharpness. The blades are mounted at a reduced angle A between each blade portion bearing the cutting edge and a reference plane (200) tangential to the cutting edges of the first and third blade. Individual longitudinal members (150, 160, 170) of the over-guard that lie over each blade and have a progressively decreasing height H1, H2, H3 above the reference plane in a front to back direction of the razor cartridge. A further longitudinal member (140) is forward of the first blade and has a height H0 above the reference plane.

摘要： A safety razor handle (20) has a body (21) having a cartridge attachment end (24) with an adjoined elongated hollow portion (22) terminating in an opening (44) at an opposed end (26) of the body. A pushbutton (50) is slidably retained in the opening and movable along an axis (42) of the hollow portion between an at- rest position and a depressed position. An elongated transfer rod (60) is located in the hollow portion and has a first end (62) in the cartridge attachment end region of the hollow portion and a second end (64) closely abutting the pushbutton. A compression spring (70) acts between the cartridge attachment end and the first end of the transfer rod to bias the transfer rod along the axis towards the opening. An ejector (80) is mounted in the cartridge attachment end having an outer end (84) extendable outwardly from the cartridge attachment end and an inner end (82) closely abutting the first end of the transfer rod.

摘要： A safety razor 10 has a handle 12 with an extension 30 having a pair of depressions 34 to each receive a respective one of two detents 56, 58 of a razor cartridge 14 and which extension provides cartridge support structure that engages a recess 50 of the razor cartridge. The razor cartridge has a blade unit 16, 18 and a connector 20. The recess of the razor cartridge is in part defined by opposed walls of the connector providing a floor 60 and a ceiling 70 and the two detents are on the floor and extend into the recess. The floor has a slot 90 between the two detents and the slot is sized such that deflection of any one detent on its respective floor portion is substantially independent of deflection of the other detent on its respective floor portion.

摘要： A lubrication box for a shaving cartridge has a body including an upper wall and a sidewall in combination defining a cavity. The upper wall has an aperture. A support structure is disposed within the cavity. The support structure has a plurality of support structure apertures that extend, directly or indirectly, from the upper wall aperture. A solid shaving aid material is disposed within the cavity, the shaving aid material at least partially filling the upper wall aperture and the support structure apertures. A lid is attached to the sidewall such that the cavity is substantially closed. The support structure can be integrally formed with the body or the support structure and body can be separate structures. The support structure apertures can be aligned with the upper surface aperture or can be relatively angled.

摘要： A razor cartridge handle configured to be connected to first and second type razor cartridges, which first and second type razor cartridges are different from one another, is provided. The handle includes a cartridge end, a first assembly, a second assembly, an ejector, and a plunger. The first assembly is configured to connect the first type razor cartridge to a cartridge end of the handle. The second assembly is configured to connect the second type razor cartridge to the cartridge end of the handle. The razor cartridge ejector is operable to selectively eject both first type razor cartridges and second type razor cartridges. The plunger is normally biased to a position where a distal end of the plunger is in contact with the attached razor cartridge.

摘要： A method for making a razor blade having a bent portion is disclosed. The method includes: providing an elongated strip of stainless steel that can be 0.076 mm thick; hardening the strip; providing a cutting edge along an edge of the strip and providing coating(s) on the cutting edge. The stainless steel has a carbon content preferably between 0.45% and 0.55% by weight. The strip is separated lengthwise into discrete razor blades. The bent portion of the razor blade is then formed using a swivel bending process. When the razor blade is bent to define an included angle of 90 degrees between planar regions adjacent the bent portion and an inner surface having a radius about 0.3-0.35 mm, the outer surface of the bent portion is free from macro-cracks.

摘要： A safety razor (20) has a blade unit (30) with a housing (32) and a razor blade (34), and an elongated handle (40) having a uniform thickness and having a first end (44) including an aperture (46) extending into the thickness, and an opposed second end (48). The safety razor also has a connector (60) to connect the blade unit to the handle. A body (62) of the connector has a recess (64) with an opening (66), and a user- operable latch (68) including a protrusion (70) extending into the recess. The first end of the handle is removably received in the recess and the protrusion is received in the aperture to secure the handle to the connector. The protrusion is releasable from the aperture by a user-applied force to a lever (74) at an end of the latch opposite the protrusion end to release the first end of the handle from the recess.

摘要： A razor blade has a first and a second portion. The first portion has a cutting edge at an exterior end and is angled relative to the second portion by a bending process. A bent region that can be arcuate is intermediate the first and second portions. The razor blade is manufactured from martensitic stainless steel being mostly iron and having (by weight): 0.40 to 0.60% C; 0.30 to 0.55% Si; 0.70 to 0.90% Mn; 13.0 to 14.0% Cr; 0.50 to 1.0% Mo; and 0.03 to 0.2%, more preferably 0.03-0.1% N.
