    摘要： Methods of manufacturing razor cartridges are provided. One method includes loading a support portion of a supported blade into an elongated blade slot defined by a core member, the core member being configured to define a portion of a molding cavity defining the shape of the cartridge housing; and delivering a resin to the molding cavity to form the housing and capture a portion of the blade in the resin. In another method, a plurality of razor cartridges are manufactured substantially simultaneously by (a) removably mounting each blade on a core member; (b) placing each core member in a molding cavity; and (c) delivering a resin to the molding cavities to form at least a portion of the cartridge housing and capture a portion of the blade in the resin. In other methods a flexible region is provided adjacent the blade ends by: (a) delivering a compliant material to the molding cavity to capture at least the ends of the blade; (b) placing the blade and molded compliant material in a second molding cavity defining the shape of the molded housing; and (c) delivering a resin to the second molding cavity to form the molded housing, or by (a) providing coring areas in the molding cavity beyond each of the blade ends, configured to provide a flexible region of plastic adjacent each blade end in the finished product; and (b) delivering a resin to the molding cavity. In some methods, the resin is delivered through a gate that is positioned so that a substantial portion of the resin flow goes by the blade ends before the molding cavity is filled.

    摘要： Tooth cleaning devices. An embodiment of a tooth cleaning device includes: an elongated head sized to fit in an oral cavity. The elongated head having a first surface and a neck extending from the head. A first tooth cleaning element having a plurality of upstanding wiping members extends upward from below the first surface and extends radially outward from a center of the first tooth cleaning element. Each upstanding wiping member has a free outermost edge that extends upwards substantially from the first surface to the top of the wiping member. A plurality of upstanding arcuate shaped second tooth cleaning elements secured to the head and located outboard of the first tooth cleaning element are also provided. In addition, a plurality of upstanding third tooth cleaning elements are secured to the head and border an edge of the first surface. The third tooth cleaning elements have a circular cross-sectional area.
