The Funtainer comes in a lot of different colors and themes that kids will love. More importantly, a wide brim makes it easier for kids who are just learning how to use tools to eat, and the outside won’t hurt their hands because it stays cool. Best of all, it’s small and light enough for kids to open with their little hands and put in their lunch box.

It’s important to follow the directions exactly, like warming the inside with hot water for five to ten minutes before putting food in there that will be eaten later. When we did this at home, we found that it kept hot food hot for five hours, even if we opened it every hour to check the temperature. It also kept drinks cold for seven hours, and at the end of the test, ice cubes could still be seen. Overall, it is one of the best food thermos that you can buy.

The BPA-free Foogo is a favorite of parents because its 10-ounce body, which stays cool to the touch, is the perfect size for a child’s lunch. The base and lid are both made of rubber, which makes it easier for people with smaller hands to hold on to the jar. Other benefits include a low price and a tough, scratch-proof body. Our home tester liked that it was insulated with two walls and that it was small enough for people to use for hot sides and drinks. Still, it is one of the best food thermos that you can buy.

But our writer focused on one of the most important things about a thermos: how long does it keep food hot? Thermos says this can keep food warm for up to five hours, but in our tests, it didn’t do that well. Mac and cheese only stayed hot for two hours. After four hours, it was still warm enough to eat, but by hour five, it needed to be heated up again in a different container. When it came to cold drinks, it did last nine hours, as ice cubes were still there after a full workday.

The Thermos King is said to keep food hot or cold for as long as possible because of its super-tight seal. This is because two walls of stainless steel keep the heat in. The lid is also a big plus because it can be used as a bowl with the standard-sized stainless steel folded spoon that comes with it. Overall, it is one of the best food thermos that you can buy.

Thermos King says this can keep liquids hot for nine hours and cold for up to 14 hours, so we put that promise to the test in a home kitchen. Our tester put all 16 ounces of freshly made mac and cheese in the thermos and opened it every hour to check if the temperature stayed the same. The temperature didn’t drop until the ninth hour. Also, it did a great job of keeping water ice-cold. After 14 hours, our tester could still see ice cubes in the thermos.

FAQs

What is a food thermos?

A food thermos is a container that keeps food hot or cold for a long time. It is also called a food flask or food jar. It is made up of a cylinder with two walls and insulating materials that help keep the food at the right temperature.

How does a food thermos work?

Most food thermos cases are made with two walls, which makes an air layer between the inner and outer walls that keeps the food warm. Most of the time, the inner wall is made of stainless steel, which helps keep the food warm. The vacuum-sealed space between the walls stops heat from moving through conduction and convection, so the food stays hot or cold for longer.

How long can a food thermos keep food hot or cold?

How long a food thermos can keep food hot or cold relies on the quality of the thermos, the initial temperature of the food, and the temperature of the room where the food is kept. A well-insulated thermos, on the other hand, can usually keep food hot for 4 to 6 hours and cold for 6 to 8 hours.
