Abstract: A razor blade unit for safety razor has optimized shape and dimensions for body shaving, especially the regions of the axillae. The blade unit has an elongate blade with a rectilinear sharpened edge, and a skin contacting surface at which the length is 1 to 4 times the width and not greater than about 60 mm, e.g., 40 to 45 mm. The skin contacting surface has a footprint area of at least 450 mm2, e.g., 600 to 750 mm2, and a circularity which is not less than the lower of (i) 65%, and (ii) the circularity of a rectangle with the same length and width as the skin contacting surface and with corner radii of 30% of the width. In a plane perpendicular to the blade edge the skin contacting surface is convex and shaped to make at least a three point contact with an imaginary circumscribing circle with a radius of 15 to 70 mm, e.g., 25 mm. Guard cap surfaces in front of and behind the blade edge each have a skin contact area of at least 140 mm2,and their combined area is preferably at least 400 mm2, e.g.

Abstract: A safety shaving assembly for attachment to a razor handle has optimised shape and dimensions for body shaving, especially the regions of the underarm. The shaving assembly has an elongate blade with a linear sharpened edge, and a skin contacting surface whose length is 1 to 4 times the width, preferably 1 to 2.8 times the width, has a large footprint area of at least 450 mm2, preferably at least 600 mm2, and a circularity (as herein defined to relate the area enclosed by the perimeter to the length of the perimeter) of not less than 70%. The shaving assembly is substantially inflexible over a major longitudinal dimension in use. In preferred embodiments the circularity is about 80%. A preferred shape is an oval resembling a rectangle with semi-circular ends. The forward and rearward skin-engaging surfaces in front of and behind the blade edge each can have a skin contact area of at least 140 mm2, and their combined areas is preferably at least 400 mm2.

Abstract: A shaving system comprising a razor handle for detachably mounting a blade unit, and a dispensing container housing a plurality of blade units side by side in a row between entry and exit ends of the container, the handle being arranged to be guided along the container during blade unit replacement for disengaging and leaving the blade initially thereon at the trailing end of the row, and for engaging and withdrawing from the container the leading blade unit, the blade units each having a guide for guiding the razor handle along the container.

Abstract: A safety razor blade unit (FIG. 1) comprises at least one elongate blade (1, 2) and a skin-engaging member (3) extending longitudinally of the blade or blades (1, 2) and defining a surface (9) exposed for contact with the skin during shaving. A plurality of pockets (10) is provided in the skin-engaging member (3) for holding respective portions of a shaving enhancement product (FIG. 2). The pockets (10) are distributed along the surface (9) and across the width thereof in an array spanning substantially the whole of the area of the skin-contacting surface (9). The pockets (10) can be in communication with reservoir chamber (4) containing the shave enhancement product.

Abstract: The tandem blades of a razor can be protected when not in use for shaving, without disturbing a pre-set shaving geometry and with reduced risk of damage to the blades and the fingers of a user during manipulation, by providing a shaving cartridge 11 which is movable, relative to a handle 10 of the razor, for retraction behind a shield 23 formed in the handle. Also disclosed are means to provide, in such a razor, replaceable cartridges for a permanent handle which includes a cartridge carrier 61.

Abstract: A safety razor blade unit has cap structure with upstanding fin elements directed perpendicular to the blade edges to define a cap surface featuring low frictional resistance characteristics during shaving. The fin elements are spaced at a pitch distance of 0.3 to 0.7 millimeter, are 0.3 to 1.0 millimeter in height and are substantially triangular in cross-section with an aspect ratio of 2:1 to 4:1.
