Food containers with cold accumulator

 

— the purpose of this device is well described already in the name: the cold accumulator is able to “accumulate” cold (for example, after lying in the refrigerator), and then “give it away” to the contents of the container, slowing down the temperature rise inside. This function will be useful in all cases when you want to keep food cold for a long time, but it is especially useful for storing perishable products that do not tolerate heat well.
