Best Soup Flasks UK Reviews

Thanks for taking your time to read our information on the best soup flasks that are currently available on the UK market. Many people like a hot lunch, or simply want to have really hot soup on a day out. A great way to ensure that happens is to own the best soup flask. Many people refer to a soup flask as a thermos.

In the better quality  flasks, soup can stay hot for between 5-7 hours. The secret is to make the soup hotter than you normally would at home. Then pour it into the flask. That way it stays hotter for longer.

Many people also use these to keep their pasta warm, stews, casseroles and some even keep their hot dogs in them. Many buyers also recommended that you avoid foods like curry, as they do leave an after taste in the flask. Some people even buy a separate flask to accomplish that task.

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.

Soup Flask Key Features

Material - Almost of all the better flasks are made from some form of 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.

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
