The choice really depends only on your needs and preferences. Of course, you would want to have a thermos that is just of the right capacity – not more, not less. This is probably the first thing you pay attention to when you set your mind on buying a food thermos or a flask. Just like any other product, they all have their pros and cons, but at large they are among the best options on the market. We have picked seven vacuum food thermoses and flasks that are high-quality, convenient and affordable. Such vacuum containers and flasks can keep food and drinks hot for up to 12 or even 15 hours. Some manufacturers have special series of products designed to address travelers’ needs. If you travel a lot, especially in the wintertime, you need a reliable thermos or flask that will surely retain heat for a very long time. Avoid closing the lid if the thermos is still wet inside to prevent it from developing bad smell. After you’re done with the meal, you should clean the thermos thoroughly and let it air dry. Otherwise, it might go bad and cause food poisoning. Nevertheless, you should not keep your food in a vacuum thermos or flask longer than the time specified by the manufacturer. In that case the meal will stay hot longer. To achieve a better result you can fill the thermos with boiling water and let it rest for about 10 minutes and pour it out before putting your food in. Then you fill it up with your favorite homemade meal (it should be freshly cooked and hot) and screw the lid on tightly. First, you should make sure the inside of the flask is clean. Many food thermoses come with spoons for added convenience. The main difference is that food thermoses have wider mouths as compared to flasks, so that food can be easily put in and taken out. They use the same vacuum insulation technology to keep the contents hot or cold. Is there a difference between a food thermos and a thermos for beverages?īoth food thermoses and beverage flasks have similar constructions. The lid of a thermos should also be insulated (usually with foam, not vacuum). This material is absolutely hygienic, but rather fragile and therefore less popular than stainless steel. The inner part of the vacuum thermos can be made of glass as well. Stainless steel is the most widely-used material, both in inner and outer reservoirs. You should also pay attention to the quality of materials. Most of the modern thermoses have vacuum between inner and outer walls as a means of insulation. The main characteristic of a good thermos is quality of insulation. Aside from that you might also want to consider the following aspects. To sum up, vacuum insulation and premium grade stainless steel are the most important features of a good thermos. 18/10 grade steel is even better, but it’s not that popular and is usually more expensive. It is also the most common one among high-quality kitchenware. This is the optimal grade, which ensures that the product is protected against oxidation (rust) and corrosion. The numbers indicate percentages of chromium and nickel in the alloy. Most of the manufacturers of thermo food containers and flasks use 18/8 grade stainless steel. Naturally, in order to use vacuum as insulator a thermos or flask must be made of stainless steel, not plastic. In contrast to foam-insulated thermoses the former show better performance at temperature retention. Who doesn’t want to enjoy steaming hot homemade lunch at work, at school or on a trip? Today it is easy thanks to a wide range of insulated food containers and flasks available on the market.
