I heated the container with boiling water then replaced then lid. I heat my soup until it boiled,emptied the water out,placed the soup in the tub and placed in the container,lid secured.the food only kept hot for about 4 hours,but was still warm after 6 hours if you can eat your food tepid. Better for keeping items cold
