  • Publication number: 20140106145
    Abstract: A tableware item molded from a plastic material, such as polystyrene has a metallic coating applied to at least one surface by a sputtering deposition process. The sputtered coating is suitable for food contact without an overcoat, and imparts the appearance of a metal tableware item. In embodiments, the tableware item is a cup, a plate, a bowl, a tray, a lid, a glass, a champagne flute, a goblet, a napkin ring, a candle holder, or a centerpiece receptacle. The metallic coating can be silver, steel, stainless steel, chromium, aluminum, copper, or gold. In some embodiments, the metallic coating is not applied to all surfaces of the tableware item. In various embodiments, the tableware article is molded from a clear polystyrene resin and coated with a thin stainless steel layer on only one side. The abrasion resistance of the metallic coating can be enhanced by applying a clear protective overcoat.

  • Patent number: 8621755
    Abstract: A plastic cutlery item molded from a plastic material, such as polystyrene, having a metallic coating that imparts to this cutlery item the appearance of metal cutlery or silverware. In one embodiment the plastic cutlery or tableware items are molded using injection molding techniques, and subjected to a vacuum metallizing process in an individualized non-contiguous manner, where a thin metallic layer is deposited on at least one of their surfaces. The resultant items simulate the appearance of metal cutlery or tableware. In one embodiment of the invention the plastic cutlery or tableware articles are molded from a clear polystyrene resin and are coated with a thin stainless steel layer through vacuum sputtering deposition on only one of the sides. The abrasion resistance of the metallic coating can be enhanced by subjecting the articles to a post-metallizing holding period or by applying a clear protective overcoat.

  • Patent number: 6983542
    Abstract: A plastic cutlery item, fabricated primarily from a plastic material, such as polystyrene, having a metallic coating that imparts to this cutlery item the appearance of metal cutlery or silverware. The plastic cutlery or tableware items are molded using traditional injection molding techniques, and subjected to a vacuum metallizing process in an individualized non-contiguous manner, where a thin metallic layer is deposited on at least one of their surfaces. The resultant items simulate the appearance of solid metal cutlery or tableware. In the most preferred embodiment of the invention the plastic cutlery or tableware items are molded from a light-transmitting grade of Polystyrene resin and are coated with a thin stainless steel layer through vacuum sputtering deposition on only one of the surfaces.
