Abstract: A package comprises two or more toothbrushes which are dated to indicate a service period such as by designating a starting date and/or an ending date, or some other date in the service period. The service periods are sequential and add up, ideally, to one complete year so that a package, purchased at any time during a year, provides toothbrushes that can be used for twelve sequential months. Providing sequentially dated toothbrushes provides an indication to the user to discard used toothbrushes at the ends of the service periods thereby promoting dental health as recommended by dentists and toothbrush manufacturers. The service period indicator may be numbers, letters, words, symbols, colors, figures or any combination that suggests a period of service of a particular toothbrush and may be placed at any suitable location on each toothbrush. Suitable instructions, placed on and/or in the package or separate from the package, are preferably provided to inform potential users of the meanings of the indicators.

Abstract: A heat extracting substrate is moved along a melt front formed at the edge of the surface of a molten material so that a layer of molten material is deposited on the substrate, cooled and removed from the substrate to form ribbon, filaments, fiber or film directly from the molten material. The edge may be formed by providing an upper edge upon a portion of the wall of a receptacle lower than the top of the receptacle. The molten material may be overflowed over this relatively horizontal edge and against the moving substrate surface.
