Abstract
An improved skin engaging device for use in razor cartridge assemblies and shaving systems of the wet shave type. In an embodiment, there is provided a two-component, control-release device having a sheath layer made from thermoplastic resins with openings in its skin engaging surface, coextruded with a core region containing shaving aids. At least one end of the device is at least partially closed to inhibit the ingress of water at that end of the device and to inhibit the release of the shaving aid from that end of the device during a normal shaving operation. Enclosure of the end of the device can be by addition of an end cap, by application of a film of a suitable sealant or by suitably joining opposed inner walls of a portion of the sheath extending beyond the core.
