发明名称 PROCESS FOR INSERT MOLDING WET-SHAVING RAZOR UNIT AND UNIT MADE THEREFROM
摘要 The present invention provides a wet-shaving razor unit with at least one exposed blade edge (E) for shaving which comprises a continuous thermoplastic body (9) to which the blade (B) is secured against movement and vibration during shaving. The body (9) includes skin-engaging portions which provide a constant shaving geometry over the length of said blade. A method of producing the razor unit is also provided in which the blade (B) is supported in a mould with the edge (E) surrounded by male mould members (M1, M2, M3). The blade (B) is mechanically buttressed on both sides and thermoplastic material is injected into the mould to provide counterbalancing high pressure on both sides of the blade (B) during moulding to prevent deformation of the blade (B). <IMAGE> <IMAGE>
