What’s the best food thermos like?
The main characteristic of a good thermos is quality of insulation. Most of the modern thermoses have vacuum between inner and outer walls as a means of insulation. You should also pay attention to the quality of materials. Stainless steel is the most widely-used material, both in inner and outer reservoirs. The inner part of the vacuum thermos can be made of glass as well. This material is absolutely hygienic, but rather fragile and therefore less popular than stainless steel. The lid of a thermos should also be insulated (usually with foam, not vacuum).
Is there a difference between a food thermos and a thermos for beverages?
Both food thermoses and beverage flasks have similar constructions. They use the same vacuum insulation technology to keep the contents hot or cold. 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. Many food thermoses come with spoons for added convenience.
How to use a thermos for hot food?
It’s very simple. First, you should make sure the inside of the flask is clean. Then you fill it up with your favorite homemade meal (it should be freshly cooked and hot) and screw the lid on tightly. 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. In that case the meal will stay hot longer. Nevertheless, you should not keep your food in a vacuum thermos or flask longer than the time specified by the manufacturer. Otherwise, it might go bad and cause food poisoning. After you’re done with the meal, you should clean the thermos thoroughly and let it air dry. Avoid closing the lid if the thermos is still wet inside to prevent it from developing bad smell.
How can I keep food warm when traveling?
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. Some manufacturers have special series of products designed to address travelers’ needs. Such vacuum containers and flasks can keep food and drinks hot for up to 12 or even 15 hours.

Finding the Best Way to Keep Food Warm: Insulated Food Container Buyer’s Guide
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. However, not all thermoses are the same. Vacuum insulated ones are the best. In contrast to foam-insulated thermoses the former show better performance at temperature retention. Naturally, in order to use vacuum as insulator a thermos or flask must be made of stainless steel, not plastic.
Most of the manufacturers of thermo food containers and flasks use 18/8 grade stainless steel. The numbers indicate percentages of chromium and nickel in the alloy. This is the optimal grade, which ensures that the product is protected against oxidation (rust) and corrosion. It is also the most common one among high-quality kitchenware. 18/10 grade steel is even better, but it’s not that popular and is usually more expensive.
To sum up, vacuum insulation and premium grade stainless steel are the most important features of a good thermos. Aside from that you might also want to consider the following aspects.
This is probably the first thing you pay attention to when you set your mind on buying a food thermos or a flask. Of course, you would want to have a thermos that is just of the right capacity – not more, not less. The choice really depends only on your needs and preferences. How large of a serving do you want to carry with you? Are you getting a thermos only for yourself or do you need the one that can be taken to family picnics to serve food or beverages from it? Is this a thermos for an adult or a kid? Answering these questions will help you make a decision. Fortunately, food thermoses and thermal flasks come in so many different sizes that you will definitely find the right one to suit your needs.
Most vacuum flasks and thermoses have approximately the same temperature retention capabilities. As usual, it’s 5-6 hours for hot food and around 12 hours for cold. In a regular scenario, when you just need to take hot food for lunch at work (or to send your child to school with a hot lunch) this is more than enough. However, if you leave home very early, have a hectic schedule with no fixed lunch time or travel a lot, you might need a thermos with better heat retention. There are vacuum flasks that can hold heat for up to 15 hours. They are usually more expensive but are worth their money.
Your vacuum thermos is a container where your food will stay for 5 to 10 hours. Thus, it must be safe, i.e. not to contain any harmful elements, such as BPA, phthalates, and others. Responsible manufacturers make their thermoses and flasks only with food-safe materials, including stainless steel, silicone, polypropylene and other types of safe plastic. If you feel unsure about safety of plastic when it comes in contact with hot food, you can choose a flask that is all stainless steel on the inside.
Wideness of the mouth
This characteristic usually defines how convenient it would be for you or your child to eat out of the flask. It’s always better to have a thermos with a wide mouth, unless it has a lid that can be used as a bowl.
Before buying a vacuum thermos, you should make sure you will feel comfortable carrying it around. This is especially important when you are getting one for your child. Most vacuum thermoses and flasks are not too heavy, but there are some extra-durable models with thick walls, which are not very appropriate for everyday use.
Ease of use
To have only positive experience with your vacuum thermos or flask you should choose the one that is user-friendly. What does that mean? First of all, it should be easy to unscrew. The lid should be large enough to provide a good grip (better yet textured or even with dents). If it’s a large flask, it should have a handle to be carried by.
To stay hygienic and safe it is important that your vacuum thermos receives proper cleaning after each use. The flask should not have inner seams or other tricky spots, which will be hard to clean. This is especially important if a particular thermos can only be cleaned by hands. However, some vacuum thermoses are dishwasher safe and that might be a significant advantage.
