Buyer’s Guide - Best Kids’ Thermoses & Food Jars

When it comes to choosing a thermos for your child’s school lunch, there are a few things you’ll want to keep in mind. Some of the most important factors that we based our ranking on include: size, material, heat retention, outside temperature, and lids. Price is obviously something to consider as well, but we left that out and opted to find five within a reasonable price range.


Volume is important to consider when purchasing a thermos for your child. A good rule of thumb is to choose a size that can accommodate at least two cups of food. This will ensure that there’s enough space for a hearty portion, as well as leftovers if need be!


When it comes to material, there are a few different options. The most popular choice is stainless steel, as it doesn’t retain flavors or scents and is very durable. Look for a thermos with double-wall vacuum insulation, as this will ensure that your child’s food stays at the perfect temperature.

Heat Retention

One of the most important factors to consider when choosing a thermos is how well it retains heat. Look for a model that can keep food hot for at least five hours, as this will ensure that your child’s lunch stays warm until they’re ready to eat it.

Outside Temperature

A thermos needs to be cool to the touch because that means that no heat is escaping it. If there is, then heat will be escaping the thermos making the outside temperature hot and potentially burning your kid's hands.


A good lid is crucial when picking a thermos for your kid. You want something that will keep contents inside secure, but not is difficult for your kid to open at lunch. Look for a model with a tight-fitting seal to prevent leaks, as well as a wide opening for easy access. Some lids even come with built-in utensils, which can be handy if your child forgets theirs at home.
