Frequently Asked Questions
Is this food jar safe for my child to use independently at school?
Yes. The push-button flip-top lid is designed for one-handed operation by small hands, and the integrated foldable spoon stores right in the lid so kids have everything they need to eat without adult help. The exterior stays room temperature, so it will not burn little fingers.
Will the wide mouth make it easy for my kid to eat chunky foods like pasta or fruit?
The 16 ounce jar features a wide-mouth opening that fits a standard fork or the included foldable spoon, making it easy to scoop up pasta, soup with vegetables, oatmeal, or yogurt with berries. It also makes hand-washing the inside simple for parents.
Is the stainless steel durable enough to survive being dropped in a school backpack every day?
The jar is made from 18/8 stainless steel double-wall construction that is built to handle daily drops, dings, and the rough treatment of being tossed into a backpack. It is the same grade of steel used in adult outdoor bottles, just sized for kids.
Will this fit inside my child's standard lunch box?
The compact 3.46 x 3.72 x 6.65 inch footprint is designed to slide into most standard kids' lunch boxes. At only 0.6 pounds empty, it adds very little weight to whatever bag or backpack your child is already carrying.
Is it safe for a preschooler or toddler in daycare?
Yes. The BPA-free materials, food-grade 18/8 stainless steel, and secure push-button lid make it appropriate for daycare and preschool use. Staff can pre-fill it with hot soup, pasta, or cold snacks and know the temperature will hold until mealtime.
Where is the best place to buy a matching set for my whole family?
You can purchase the FUNTAINER directly through Thermos brand retailers and many multi-pack listings on major marketplaces. Buying a multi-pack is a popular way to color-coordinate a jar for each family member so no one mixes up their lunch at school.
Can my 5 year old open the lid without help?
Yes, the push-button mechanism is intentionally designed for young children ages 5 and up to operate with one hand. There is no twisting, no unscrewing, and no sharp edges. Kids can flip it open at lunch, eat with the foldable spoon, and snap it shut again on their own.
Will food taste metallic or like leftover soap after washing?
No. The 18/8 stainless steel interior is non-reactive, meaning it will not transfer flavors, odors, or metallic taste to food. As long as you rinse it after washing, yesterday's mac and cheese will not show up in today's apple slices.
How does it compare to a plastic kids' lunch container?
Unlike plastic containers, this vacuum-insulated jar keeps hot food hot for 7 hours and cold food cold for 9 hours, so soup stays warm at lunch and yogurt stays cool in a warm classroom. Stainless steel is also more durable, more hygienic, and free of BPA and other plastic concerns.
Is it better than a thermos brand I have never heard of?
Thermos brand has been making insulated products for over 120 years, which means the vacuum seal, lid threads, and stainless steel grade have all been refined over generations. Cheaper unbranded jars often lose their insulation ability within a year, while a Thermos jar is built to be passed down to siblings or cousins.
What if my child is a picky eater and the food goes uneaten, will it leak in the backpack?
The push-button lid creates a tight seal when closed properly, so the jar is designed to be leak-resistant in a backpack. We still recommend transporting it upright and confirming the button is fully snapped down before packing, especially with very liquid foods like soup.
Is the outside of the jar going to feel hot or cold when my child picks it up?
No. The double-wall vacuum insulation keeps the exterior at room temperature regardless of what is inside. Hot soup will not warm the outside, and cold yogurt will not cause condensation on the outside, so it is comfortable and safe to hold in any weather.
Will my child actually use the foldable spoon or lose it on day one?
The spoon folds and clicks securely into the lid, so it stays attached to the jar even when tossed in a backpack. Kids cannot accidentally throw it away with a disposable utensil, and parents do not have to remember to pack a separate spoon each morning.
What if the paint or finish chips off after a few months?
The matte black finish is designed for daily school use, but like any coated product, heavy abrasion can eventually wear the finish. The stainless steel underneath remains fully functional and food-safe, so a cosmetic chip will not affect the insulation or safety of the jar.
Is the lid dishwasher safe too, or do I have to hand wash it?
Yes, both the jar and the lid are top-rack dishwasher safe, which is a major time-saver for busy parents. Just pop both pieces in after school and they will be clean and ready to pack again the next morning.
How long will soup actually stay hot until lunchtime?
In testing, the vacuum insulation keeps soup hot for up to 7 hours when pre-warmed properly. For best results, fill the jar with hot (not just warm) food right out of the pot and close the lid right away. Packed at 7 a.m., it will still be steaming at noon.
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.
