Abstract

This invention relates to an improved skin engaging member (64) for use in razor blade cartridge assemblies and shaving systems of the wet shave type. In accordance with one aspect of the invention, there is provided a two-component, control-release shaving device consisting of (a) a sheath layer (72) made from thermoplastic resins with openings therein and (b) a core region (70) containing internal shaving aids. Potentially, the device can maintain surface appearance, control-release the shaving aids, minimize the degradation of the shaving aids, and prevent the shaving aids from being trapped in a strip. Furthermore, the addition of low-melt additives to the shaving aids becomes feasible and the compatibility between the shaving aids and the shaving aid carrier such as polystyrene in the lubricating strip composite becomes less critical.
