Abstract
A cooking and/or boiling utensil for bottom thermal energy application through thermal conduction or through electromagnetic induction. The container has a round horizontal section of austenitic steel, a thermal distribution plate of suitable thickness flush against the container base of a metal with a good thermal conductivity, and a ferromagnetic plate cover against the thermal distribution plate. The ferromagnetic metal plate cover has cover recesses mainly formed as radial slots. The radial slots start at the center and end inwardly of the cover collar. The sandwich unit consisting of the container base, the thermal distribution plate and the plate cover is substantially deformation-proof due to adjustment of the container thickness of the container base and the container thickness of the plate cover on one hand and the length and width of the slots and the diameter of the center on the other, during thermal energy application through thermal expansion.
