FIELD: personal use articles.

SUBSTANCE: invention relates to a safety razor cartridge design. The invention describes the geometry of a lubricating body, strip or overlay. Auxiliary shaving means are considered with account for their shape, the materials used for manufacture and their positioning in interaction with multiple blades to improve shaving characteristic when wet shaving systems are used. The maximum height of the projecting part of the strip is in excess of or equal to the blades plane maximum height. Thus, the surface of the lubricating strip contact with the skin is usually positioned over the surface of the blade contact with the skin. The strip or overlay is capable of delivering a lubricant onto the user's skin during shaving to reduce drag, helps to smooth away the skin to ensure effective and clean shaving and acts as an arm bearing par of the load caused by the pressure the user exerts on the cartridge. In cases when a coloured strip representing wear indicator is embedded into their top surface, the strip or overlay signals cartridge replacement time approach.

EFFECT: overlay additionally ensures safety since in the process of shaving it is positioned up ahead with the blades positioned behind incapable to cut the user's skin.
