## Description

Get your kids ready for school lunch or snack time with the THERMOS FUNtainer 10oz Vacuum Insulated Stainless Steel Food Jar with spoon that keeps hot foods hot and cold foods cold. Designed for kids, our insulated food containers come in different fun colors and patterns for any elementary or middle schooler to choose from. Perfect for back-to-school season and daily packed lunches year-round. With its double-wall stainless steel construction, your child gets a hot and fresh lunch even hours after you packed it. If they're in the mood for a cold snack, pack it up with yogurt and berries, or apples and peanut butter. It includes a foldable spoon and compact design, ensuring it fits most standard lunch boxes, and your kid always has their utensils ready to go. Use it as an all-in-one lunch solution; food and utensils in one leak-proof container when closed, so your child can enjoy a warm lunch at the table. Our insulated lunch containers are sweat-proof and lightweight with a push-button lid and wide-mouth opening, so they're easy to eat from, carry and clean. For maximum thermal insulation efficiency, preheat or pre-chill with hot or cold tap water, attach the lid, and let stand 5 to 10 minutes before using. Built for the picky eater who needs food to stay just the way they like it, and the busy parent who wants lunch prepped the night before. To clean, you can pop your Thermos FUNtainer food jar in the top rack of your dishwasher. However, hand washing is recommended. Our kids food jar is BPA-Free and stays cool to the touch with hot contents.

Review: preheat it with hot water for the best results - The THERMOS FUNTAINER has been really great for packing kids’ lunches. It keeps food warm for hours, so things like mac and cheese, soup, or chicken nuggets are still warm by lunchtime. The 10 oz size is perfect for kids—not too big or too small—and I love that it comes with a spoon that stays attached, making it super convenient. It feels durable and holds up well to everyday use, plus it’s easy to clean. The only thing is you’ll want to preheat it with hot water for the best results, but overall it’s a solid lunch container for school or outings.
Review: Perfect for kindergarten school lunch - My son LOVES Lightning McQueen, so we grab anything with him on it. 🚗💨 This thermos is PERFECT for warm school lunches! I’ve been using it every single day for 2 months, and it still looks brand new — no scratches, no dishwasher marks. My 5-year-old opens and closes it all by himself. Portion size? Spot on for a 5-year-old. It doesn’t keep food hot for super long — after 3 hours it’s just barely warm — but honestly, that’s kind of a bonus so he doesn’t burn himself. Lightweight, super easy to open, and the spoon is fantastic. If it came with a fork too, I’d give it 6 stars! ⭐⭐⭐⭐⭐ Big thanks to the maker and seller for such a fun, high-quality product!

### ⭐⭐⭐⭐⭐ Perfect for School Lunches – Keeps Food Hot & Fresh! 🥣💙
*by G***A on April 23, 2026*

The THERMOS FUNTAINER 10 oz Food Jar in Teal has been a total win for packing kids’ lunches. It’s the perfect size for soups, pasta, oatmeal, or snacks, and it keeps food at the right temperature for hours. The insulation is excellent—hot foods stay warm until lunchtime, and cold items stay fresh without any leaks or sweating. The lid seals tightly, so I never have to worry about spills in a backpack, which is a huge relief. I also love the included spoon—it stores neatly inside and makes it super convenient for kids to use at school without needing extra utensils. The wide opening makes it easy to fill, eat from, and clean afterward. The build quality feels very durable, and it’s clearly designed to handle daily use by kids without any issues. Plus, the teal color is fun and vibrant, which makes it a favorite. If you’re looking for a reliable, leak-proof food jar for school or travel, this one is a fantastic choice. Highly recommend!
