  • FIG. 4 is a block diagram explaining the metal container processing flow of the present invention.
  • FIG. 5 is an elevational view of a metal container made according to the present invention.
    • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • Referring to FIGS. 1˜5, the present invention is adapted to process a metal container 1 that can be used in a microwave stove to cook food. The metal container processing method includes the steps of shape forming 2, deburring 3, surface treatment 4, and heat insulation coating 5. During the step of shape forming, a metal sheet material 11 is stamped into a blank container subject to the desired shape. At this time, the metal sheet material 11 of the blank container has sharp burrs 12 and sharp dents 13 on the surface and sharp burrs 12 at the cutting edge that are not visible with bare eyes. These sharp burrs 12 and sharp dents 13 will cause sparks by microwave molecules in a microwave stove. Therefore, the step of deburring 3 is necessary to remove the sharp burrs 12 and sharp dents 13 from the metal sheet material 11 of the blank container. After deburring, it proceeds to the step of surface treatment 4 where a layer of surface coating 14 is covered on the surface of the metal sheet material 11 of the blank container to fill up the gaps in the capillary holes on the surface of the metal sheet material 11 of the blank container, thereby providing a smooth surface. After surface treatment 4, it proceeds to the step of heat insulation coating 5 to cover a layer of heat insulation coating 15 on the layer of surface coating 14.
  • During the step of deburring 3, sodium nitrite solution is applied to remove the sharp burrs 12 and sharp dents 13 from the metal sheet material 11 of the blank container. During the step of surface treatment 4, phosphorous compound is coated on the surface of the metal sheet material 11 of the blank container to form the desired layer of surface coating 14. During the step of heat insulation coating 5, a coating material containing Teflon and heat insulating material at the ratio of about 100:25˜35% is coated on the surface of the layer of surface coating 14.
  • The metal container 1 thus obtained can be used to cook food in a microwave stove, baking oven, gas range, as well as electric stove.
