Sandwiched between the inner and outer layers is a void - this vacuum stops the heat from the inner layer reaching the outer layer as heat can only be conducted through particles, whether it’s in the air, through liquids or solids. If you’re buying a soup flask then it’s because you want to be able to keep your soup hot and tasty until you’re ready to eat it. However, some flasks have inferior insulation while others will keep the soup hot all day long. Think about this and compare it to your needs; nobody wants to get to lunch time to find that their food is tepid at best. Is The Flask Leakproof? Plus, the tapered top of the flask means it’s much easier to drink out of - but of course, you can use the foldable spoon as well. How does a vacuum flask work? The ValueTalks food flask is made from BPA free materials, just like the last one we looked at. It’s also designed to keep food hot or cold and will manage this for up to 12 hours. This means that it will keep food hotter for longer than the SHO but the SHO does manage up to 20 hours for cold foods so it really depends on what type of food you’ll be storing.One of the most important things to think about when buying a soup flask is how heavy it is. If you’re going to be carrying the flask around with you, the last thing you want is something that’s going to weigh you down. If the flask is already pretty chunky, just think how that weight is going to increase when you fill it. On a budget – The 720°DGREE wunderJar Food Flask makes for surprisingly good value for those not wanting to overspend on a food flask. Even with its environmentally-friendly credentials, which often come with a little extra on the price tag, this particular flask is very reasonably-priced for a flask with a solid amount of volume for single portions and exceptional build quality and style. Of course, one of the main reasons to buy a flask is to keep hot food hot. As such, heat retention is another of the most important factors to consider before buying. This heat retention time can vary hugely between around 4 hours, up to 12 hours and potentially even longer than that. This means that you have to factor in how, where and when you intend to use your flask. For single portions, a few hours is probably fine, but on longer expeditions with multiple meals, you’re naturally going to need one that’ll hold onto that heat for longer. We don’t think it’s a huge problem but obviously it depends on how long you’d need to keep your food warm. For a camping trip where you might not eat for hours, it’s not ideal but for the office, the keep-warm time should be sufficient. Food flasks vary in price depending on how big they are and how long they will keep your food warm.

Of course, there is a limit to this and eventually the soup will get cooler but some of the best soup flasks can keep the soup warm for up to 24 hours! Now that’s impressive. And you might think that this means just keeping the soup lukewarm but we’re talking still hot, so much so that you have to blow it before you can eat it. For best results, please pre-heat/pre-cool your SHO Food Flask with boiling water/ice cold water for 5-10 minutes.Fill and then close the lid.Empty after 10 minutes.If you are out and about and want some delicious soup later in the day then the best way to ensure your food stays warm is by using a soup flask. This is the main reason for buying one. But what’s more they’re so versatile; you can use them to take soup to work or when you’re out hiking, cycling, camping and so much more.
