The THERMOS FUNTAINER Kids Food Jar is a 10-ounce vacuum-insulated stainless steel food container with a folding spoon that stores in the lid. Ten ounces is sized for a child's portion of soup, pasta, mac and cheese, or oatmeal, not an adult lunch. Vacuum insulation is what lets food packed hot in the morning still be warm at midday without a microwave, which is the entire reason this category exists for schools that do not have one. The lid-stored spoon solves the recurring failure of packing warm food and forgetting the utensil. The wide mouth is sized for a child to eat directly from the jar. Best fit: elementary-age kids, schools with no microwave, and picky eaters who will only eat a short list of warm foods.
Pros
- Folding spoon stores in the lid, so the utensil cannot be left on the kitchen counter
- Vacuum-insulated stainless keeps food warm to lunchtime with no microwave needed
- 10 ounces is a realistic child portion rather than an adult container a kid will not finish
- Wide mouth lets a child eat directly from the jar without transferring food to a bowl
Cons
- Vacuum jars hold temperature but do not heat, so food has to go in already hot and the jar preheated with boiling water, or lunch arrives lukewarm

Frequently asked questions
How long does food stay warm?
Performance depends heavily on preheating. Fill the empty jar with boiling water, let it sit a few minutes, dump it, then add food that is already piping hot. Skipping the preheat is the number one reason parents report lukewarm lunches.
Can it hold cold food too?
Yes, vacuum insulation works both directions, so it keeps yogurt, fruit, or pasta salad cold through the morning just as well as it holds heat.
Is it dishwasher safe?
Thermos generally rates the FUNtainer body and lid as top-rack dishwasher safe. Hand-washing the lid gasket extends its life, since dishwasher heat degrades seals fastest.
Will 10 ounces be enough food?
Ten ounces suits an elementary-age portion of soup, pasta, or oatmeal. For an older child or a bigger eater, the larger FUNtainer and adult Thermos sizes are the better fit.
