How We Picked And Tested
For this guide, we read six roundups and articles on thermoses from publications like Good Housekeeping and Popular Mechanics and blogs like A Well Paced Life and Mighty Nest. We also checked out best-selling models from kitchen and home stores like Amazon, IKEA, Target, Walmart, the Container Store, and Storables. Then, we took a closer look at offerings from notable brands like Thermos and Zojirushi. We considered models designed for kids as well as a general audience. We preferred thermoses that come in multiple sizes and colors, and we tested smaller size options when possible because we wanted a thermos that was easily portable and fit into our picks for the best lunch box or a bag.
A great thermos should keep foods at a food-safe temperaturebelow 40 °F for cold foods and above 140 °F for hot foodsfor long periods of time. Thermoses are meant to hold liquidy foods like soups or stews, and they shouldnt leak. Because accidents happen, they also shouldnt break or dent significantly when dropped. Most companies recommend hand-washing thermoses to preserve their vacuum insulation, but the lids and jars should be intuitive to take apart and clean.
The Best Food Thermos: Stanley Adventure Vacuum Food Jar
Stanley is a heritage brand thats been making solid camping gear for decades. The Stanley Adventure food jar was a top performer across categories. It kept soup above 160ºF for over two hours, and bounced off the bricks with only the slightest scratch. It was one of the top performers in the cold retention test, but still failed to keep its contents at food-safe temperatures for two hours. For cold safety, pack this jar in a cooler with ice packs.
This jar jumped out of the pack with a never ending list of features. The Stanley is basically a portable, dishwasher-safe picnic kit. It includes a spork, a lid that doubles as a bowl, and a loop for easy carrying. These features make it an appealing option for a car or camping trip when you dont have easy access to a stocked kitchen. The only drawback is the design of the utensil holder: The spork attaches to the outside of the jar. While convenient, this placement doesnt seem very hygienic.

Make The Soup Extra Hot Before Pouring Into Your Thermos
Remember, you’re making the soup to be a good temperature to eat later in the day, not right now. So you’ll want to make your soup as hot as possible before putting it in your thermos.
It’s advised to bring your soup up to boiling point, or nearly boiling point, then quickly pouring it into your Thermos and putting on the lid so no heat escapes.
This will keep your soup hotter for longer and it’ll also mean that your soup is going to spend less time in the danger zone of 40-140ºF which is where bacteria can multiply and grow and cause your soup to go bad.
Ideally you want your soup to be above 140ºF when it comes time to drink it. This not only keeps your soup out of the danger zone where bacteria can grow but colder than this and your soup will start to feel not hot enough.

So Why Are Thermoses Better At Keeping Things Cold
Concerning heat transfer, the greater the difference in temperature between two objects, the faster the energy will transfer between them, from hot to cold. Our perception of hot and cold is also an important thing to consider in this question. Consider that room temperature is about 70 degrees Fahrenheit water freezes at 32 degrees Fahrenheit and boils at 212 degrees Fahrenheit .
Thus, the difference between room temperature and a thermos of an ice-cold drink is much smaller than the difference between room temperature and a thermos of hot soup off the stove. Now, a thermos is far from perfect, and some heat is gradually lost. Every time you open the thermos, for example, a significant amount of heat transfer will occur . However, a larger amount of energy will be transferred between coffee and the cooler air, due to the larger difference in temperature. A smaller amount of energy will transfer between the cold water and the warmer air, due to their smaller difference in temperature.
This is where human perception comes into play we will be more aware of the temperature change in the coffee than the temperature change in the water. As a result, popular opinion states that thermoses are better at keeping things cold than keeping things warm, but by percentage of heat energy transferred, thermoses are equally efficient at either end of the temperature spectrum.

What Is A Thermos
Before we can understand its intricacies, lets take a broad look at thermoses to have a clearer idea of the subject. A thermos is any container that is able to keep liquids either hot or cold, thanks to a double-walled design featuring a vacuum.
More formally known as a vacuum flask, this invention has been around since the end of the 19th century, when researcher Sir James Dewar stumbled upon it in the course of his study of cryogenics. Dewar placed two brass flasks inside of one another, and joined them at the neck. The air that became trapped between the two flasks in a thermos can be removed or evacuated, creating a vacuum inside the space.
Without any air to facilitate heat transfer, liquid placed in the inner flask will be isolated from the exterior conditions, and will thus be able to retain its temperature more effectively. Although this was a rudimentary version of a thermos, and only offered a partial vacuum, it was a huge breakthrough.

And while you’ll be carrying this thermos food jar, unlike any other models existing out there, its outward surface would neither sweat nor let you feel the high or freezing temperature from the outside, thanks to its improved and shiny double-walled construction!
Equally impressive is its interior copper lining that boosts the thermal insulation of this Blue Canyon product. Apart from its aesthetic appeal, it also occupies the long term temperature holding feature. Besides, it never leaks causing your soup or other liquid food-substances to spill inside your backpack. Hence, a perfect travel partner!
One thing to keep in mind though – before you put the soup on the container, manage to hold some hot water on the jar for like 10 to 15 minutes so to make the thermos hot itself. Then empty the pot and store your food items inside. This conscious preheating process will ensure you a hot lunch even after around 5 hours.
A life saving tip- never tighten its lid too forcefully as the metal lid stretches naturally in touch of increased heat leading the lid to stiffer closure. A snug close will assure a more realistic experience, however. And finally, it’s safe to say, you can dispose this BPA free once you’re done with this eco friendly food jar.
