Additional function like folded spoon (preferably made of stainless steel), special spaces, where you can hold small sugar bags, salt, or any other thing. A lid that can also be used as a serving bowl will surely help you in eating the meal. Of course we cannot forget about large opening. As a result, we can eat the food directly from the flask

If you want to have a food flask that guarantees great heat retention, then you should always pay attention to the description delivered by manufacturer. However, in order to increase the chances of getting great product, look for double-wall technology. An extra temperature maintenance is guaranteed by vacuum insulation system.
