Frequently Asked Questions
Is this food jar BPA-free and safe for my child?
Yes. Every component that touches food is made from BPA-free, food-grade materials. The 18/8 stainless steel interior and the lid plastics are both free of bisphenol A, phthalates, and other concerning chemicals commonly found in cheaper plastic lunch containers.
Could the outside of the jar burn my child's hands if the soup inside is hot?
No. The double-wall vacuum insulation creates a thermal barrier that keeps the exterior at room temperature, even when the soup inside is boiling hot. Your child can hold the jar comfortably at lunch without feeling any heat transfer through the walls.
Is the stainless steel interior safe for kids with food allergies or sensitivities?
Yes. The 18/8 stainless steel is non-reactive, meaning it will not leach chemicals, flavors, or allergens into food. It is also non-porous, so allergens like peanut butter or dairy residue can be fully washed out, which is important for kids with severe allergies who may share a daycare space.
Could the lid or spoon be a choking hazard for younger children?
The foldable spoon folds and clicks securely into the lid, so it cannot come loose during transport. All components are sized appropriately for school-age children 5 and up. For children under 3, we recommend adult supervision, as with any small parts.
Is the lid secure enough that it will not pop open in a backpack and leak hot soup?
The push-button flip-top lid is engineered with a positive lock that requires the button to be pressed to release. As long as the lid is fully snapped down, the jar is leak-resistant. We recommend always checking that the button is fully seated before packing the jar in a backpack.
How does this compare to a plastic microwaveable lunch container in terms of safety?
Plastic containers can leach chemicals when microwaved, especially older or scratched ones, and they do not keep food at safe temperatures during a long morning. The FUNTAINER eliminates both concerns by using inert stainless steel and passive insulation, so there is no reheating required and no plastic-to-food heat transfer.
How does it compare to glass food jars for kids?
Glass jars can shatter if dropped on a cafeteria floor or playground, creating a serious safety hazard. The FUNTAINER uses 18/8 stainless steel that is shatterproof and dent-resistant, making it dramatically safer for active kids in unpredictable school environments.
Is this safer than sending my child to the cafeteria line for hot lunch?
Sending a packed lunch in the FUNTAINER gives you control over ingredients, allergens, and portion sizes. Cafeteria food sits in warming trays for hours, which can affect both safety and taste. A home-packed lunch in an insulated jar is typically safer, fresher, and more nutritious.
How do I know the insulation is actually working and the food is still safe to eat at lunch?
Pre-warm or pre-chill the jar with hot or cold water for a few minutes before filling, and your food will hold its temperature for 7 to 9 hours. When your child opens it at lunch, the soup should still be steaming and the yogurt should still be cold to the touch, both of which are signs the food is in the safe temperature zone.
What if the rubber seal on the lid gets moldy over time?
The lid is designed to be fully disassembled for cleaning, and all parts are dishwasher safe. We recommend occasionally removing the seal and washing it separately to prevent any food residue buildup. With proper cleaning, the seal will stay hygienic for years.
Is the finish on the outside safe if it chips?
The exterior matte finish is a cosmetic coating over stainless steel. If it chips from heavy abrasion, the underlying steel is still food-safe and non-toxic. There is no lead, cadmium, or heavy metal in the coating.
Could the metal interior react with acidic foods like tomato soup?
No. 18/8 stainless steel is the same grade used in professional cookware and is non-reactive with acidic foods. Tomato soup, orange juice, and yogurt will not taste metallic, and the steel will not corrode or leach into the food.
Is this safe to put in the dishwasher with the rest of the family's dishes?
Yes. Both the stainless steel jar and the plastic lid are top-rack dishwasher safe. The materials are designed to withstand daily dishwasher cycles without warping, leaching, or degrading.
What happens if my child drops it on concrete?
The 18/8 stainless steel body is built to absorb drops and dings from daily school use. The vacuum seal between the double walls may eventually dent, but a drop will not cause sharp edges, shattering, or any immediate safety concern, unlike glass or hard plastic containers.
Is the foldable spoon safe to eat with every day?
Yes. The integrated spoon is made from food-grade plastic that is BPA-free and dishwasher safe. It is the same material standard as the lid, so it is safe for daily contact with hot and cold foods.
How can I be sure this is a genuine Thermos product and not a counterfeit?
Buy directly from Thermos brand retailers, the official Thermos website, or authorized sellers on major marketplaces. Genuine Thermos products come in branded packaging with model numbers and warranty information. Avoid third-party sellers with prices that seem too good to be true.
How do I pre-warm or pre-chill the jar for best results?
For hot food, fill the jar with boiling water and let it sit for 5 minutes, then empty and fill with your hot meal. For cold food, fill with ice water and let it sit for 5 minutes, then empty and fill with your cold snacks. This simple step dramatically extends the temperature hold time.
What is the best way to clean the jar and lid?
Both pieces are top-rack dishwasher safe. For hand-washing, use warm soapy water and a bottle brush to clean the inside, and make sure to disassemble the lid to clean under the seal. Allow everything to air dry completely before reassembling.
How long does it take to fully hand-wash the jar?
With a bottle brush and warm soapy water, most parents can hand-wash the jar and disassembled lid in about 3 to 5 minutes. The wide-mouth opening makes the interior very easy to reach, which is a major upgrade over narrow-neck water bottles.
Will this jar fit inside a bento-style or insulated lunch box?
Yes. The compact 3.46 x 3.72 x 6.65 inch footprint is designed to fit inside most standard kids' lunch boxes, including bento boxes, soft-sided lunch bags, and hard-shell insulated cases. Just check the internal dimensions of your lunch box if you have a smaller model.
Is it compatible with ice packs for extra cold retention?
Yes. The 9 hour cold retention is achieved without any ice pack, but you can pair the jar with a small ice pack in the lunch box for even longer cold hold times. It is also compatible with thermos brand ice packs sold separately.
What is included in the box when I receive it?
You will receive the 16 ounce vacuum-insulated stainless steel food jar with the push-button flip-top lid, and the integrated foldable spoon that stores in the lid. No additional accessories or batteries are required. The product is ready to use right out of the package after a quick wash.
Is this product safe for everyday use over many years?
Yes. The 18/8 stainless steel and BPA-free plastics are designed for daily use over many years without degrading. With proper care, the jar will not rust, corrode, or lose its insulation ability, which is why Thermos brand offers a 120-year heritage of long-lasting quality.
What should I do if the jar stops insulating properly?
First, make sure you are pre-warming or pre-chilling the jar before filling, as this dramatically affects performance. If insulation is still poor after proper use, contact Thermos customer service for warranty support, as the vacuum seal should last for many years under normal conditions.
What is the difference between this and a thermos food flask for adults?
The kids' FUNTAINER is sized at 16 ounces to fit a child-sized meal and a standard kids' lunch box, while adult thermoses are typically 24 to 32 ounces. The kids' version also features a child-friendly push-button lid and integrated foldable spoon, which adult versions usually do not have.
