US Patent 7089630 Hot knob

A knob assembly for use with cooking utensils, which includes a hand graspable metallic knob, a metallic bezel for the knob, a first heat insulating separator between the knob and the bezel and a second heat separator between the bezel and the cooking utensil to which the knob assembly is to be attached. The double heat insulators prevent the conduction, as well as radiation of heat, from the hot surface of the cooking utensil to the bezel and from the bezel to the metallic knob. When the assembly is tightened together, only the metallic knob and the bezel are visible and accessible, allowing for easier cleaning of the knob and for maintaining improved hygienic conditions.
