  • Publication number: 20040232142
    Abstract: A microwavable metal food-heating tray for a microwave oven is provided that includes a metal tray having a bottom surface and a plurality of insulators that are evenly distributed and vulcanized on the bottom surface of the metal tray. The insulators on the bottom surface of the tray effectively detach the metal food-heating tray from the rotating tray of a microwave oven to avoid sparks resulting from electric conduction between the metal food-heating tray and the rotating tray, when the rotating tray is metal rotating tray. However, the metal food-heating tray performs equally when used in a microwave oven having a non-metal rotating tray.

  • Publication number: 20040232143
    Abstract: A kind of metal food-heating tray for microwave oven that comprising a metal tray, characterized in that insulating ears are symmetrically distributed on the edge of the metal tray. The eared metal food-heating tray for microwave oven in this utility model is scientific in design and reasonable in structure. The insulating ears on two sides of the tray can make the operation and utilization of metal tray more convenient and thereby the tray can be taken with hand regardless of the high temperature of the foods in the tray and the hotness of the tray itself. In order to make the metal food-heating tray applicable to microwave oven-used rotating trays made of different materials, insulating stands may be evenly distributed on the bottom surface of the eared metal food-heating tray for microwave oven in this utility model.

The insulating stands on the bottom surface of the tray effectively detach the metal food-heating tray for microwave oven from the rotating tray of microwave oven to avoid sparks resulting from electric conduction between the two trays. Said metal food-heating tray for microwave oven performs equally as the metal food-heating tray for use with other than microwave oven and may be used together with both non-metal and metal rotating trays in the microwave oven.
