    摘要： The present invention relates to a skin engaging member for use in a razor blade cartridge assembly or shaving systems of the wet shave type comprising an elongated flexible sheath region and at least one elongated, rigid core region. The core region is surrounded by the sheath such that the outer surface of the core does not intersect the outer surface of the sheath. Generally, the core or cores extend axially throughout the sheath and provide sufficient mechanical strength and rigidity to provide adequate mechanical strength and rigidity to provide adequate mechanical strength to the entire skin engaging member, as initially produced, during the shaving operation and after a significant amount of shaves.

    摘要： Extrusion apparatus is employed in a co-extrusion process to produce a triangular-shaped barrel for a writing instrument. An inner layer of material is extruded in tubular form having a substantially circular cross-section. A coating layer of three strips of material, equally spaced one from the other, is co-extruded about the outer periphery of the inner layer. A combination of forces produced during the process is effective to distort the inner layer to form a product having a substantially triangular shape.
