Best Food Thermos

Whether it’s for school, work, a picnic or a hike, there are many reasons why we need – and want – to prepare a meal and keep it either hot or cold for an extended period of time. Sometimes we reach for ice packs and an insulated bag, but that can be cumbersome and inconvenient, and doesn’t help with keeping food hot. Instead, a food thermos can be the best way to keep food at the temperature you desire, all in an easy-to-carry container.

Food thermoses come in a variety of shapes and sizes to suit different needs. Large capacity ones are good for big appetites, and smaller, easy-to-open models are ideal for kids. Some food thermoses keep one item hot or cold, while others are multi-leveled and allow you to separate foods that need to stay at different temperatures.

With so much choice, you will be able to find something to please every member of your family.

We feature six food thermos containers you can buy online. Read on to see the one that you like best.

Things to look out for:

Consider these things when looking for a food thermos so you will choose one that best suits your needs:

Size: There’s no use getting a large capacity food thermos if you have a small appetite. Most food thermoses work best when filled at least three-quarters full, so putting small amounts into a large container may affect its ability to keep your food hot. Luckily, there are many sizes available, from smaller ones for children to large capacity sizes for anyone with a hearty appetite.

Functionality: The purpose of getting a food thermos is to keep your hot food hot for as long as possible. Check to make sure the one you choose has double-insulated walls for greater heat and cold retention. Most brands will mention how long their product keeps foods hot or cold. As well, you want something that is easy to use, so make sure the lid is easy to remove, especially when choosing a food thermos for kids or anyone with trouble gripping.
