Soup Flask Buying Guide
We always like to include a buying guide for any product where we have completed detailed reviews. People buy these for a variety of reasons and that could be to give one to their kids to bring a hot lunch to school, for days at the beach, for road trips and a whole variety of other reasons.
One of the most popular reasons though is to be able to take hot soup or really anything hot to work. Many parents will also simply want to be able to take hot water with them to make up milk for their babies.
How Long do Thermos Flasks Retain Heat?
It depends a great deal on the quality of the flask and how it is constructed. The really good ones will last for about 24 hours.
More typically though you should get about 12 hours of heat retention from a good quality flask. There are cheaper models available, but at best, you will get anything between 6-8 hours.
Can a Thermos Flask Keep Food Cool?
Yes it is all about the temperature inside the flask. The flask tends to stay at the same temperature as the liquid inside it, though over the hours this will slowly change.
Always a really good idea to add ice cubes to your drink as that helps a lot in keeping it as cold as possible.
Soup Flask Key Features
Material - Almost of all the better flasks are made from some form of stainless steel. It should be food quality stainless steel
Double Wall Insulation - There are essentially two walls, known as lips, which make the soup in the food flask insulated from outside temperature completely
Folding Spoon - the better flasks will come with a folding spoon which is really useful. We find most of these are just too small and if you are ever close to a camping shop, nip in and buy a proper camping spoon. They are not dear and a much better utensil to use.
Release Air Button - this helps avoid spills when you open the flask as by pushing that you can release any air pressure that has built up in the flask during transit
