Abstract
A blade cartridge including one or more blades fixed between a platform member and a cap member. The blades have apertures that allow lubricants removed from a surface of a shaver by the cutting edge of the blade to be transported through the blade and supplied to the cutting edge of the adjacent blade or to a skin engaging surface of the cap member, whichever the case may be. The apertures in the blades define flow paths that allow lubricants to reach successive cutting edges or skin engaging surfaces, thereby reducing irritation to the shaver. The blades are spaced apart by spacers that are constructed with passages that allow the free flow of lubricant through adjacent flow paths. The cap member includes passages that allow the free flow of lubricating agents through the flow paths to the skin engaging surface of the cap member. This arrangement is especially significant for razor blade cartridges having three blades, where, in conventional razor blade cartridges, the third blade and cap member are likely to encounter dry skin.
