    B.Box Insulated Food Jars – BBox Food Jar for Warm School Lunches

    Cold pasta.

    Lukewarm soup. 

    A lunch your kid refuses to eat.

    The B.Box insulated food jar solves all of it. Purpose-built for school-aged kids, the bbox food jar keeps food hot for up to 6 hours and cold for up to 8 - so whatever you pack at 7am is still at the right temperature when the lunch bell rings.

    At BentoBliss, we stock the complete b.box insulated food jar range in both sizes: the 335ml standard jar for primary school kids and the 210ml mini for toddlers and smaller appetites.

    Two Sizes. One Smart System.

    The 335ml b.box insulated food jar fits a full serve of pasta, rice, noodles, soup, or stew - enough to keep hungry primary schoolers fuelled through the afternoon. Double-wall stainless steel construction with vacuum insulation means no heat transfer and no sweating on the outside.

    The 210ml bbox food jar mini is sized for little hands - perfect for toddlers, daycare, and kindy kids who just need a warm snack-sized portion.

    What Makes the Insulated Food Jars Different?

    • Clip-in spork included - tucks neatly into the custom bumper, no loose cutlery rattling around the school bag

    • Easy-grip handles - give kids enough leverage to open the jar independently from kinder age

    • Lid stop feature - prevents overtightening so kids aren't wrestling it open at lunch

    • 304 food-grade stainless steel - no plastic touches food inside; BPA-free and built to last

    • Dishwasher safe - lid and base both top-rack safe for easy cleaning

    Pro Tip: Get Better Heat Retention

    Pre-heat your b.box insulated food jar by filling it with hot water for 2–3 minutes before adding food. This simple step dramatically extends how long meals stay warm - especially useful for soups, curries, and pasta sauces.

    FAQs

    1. Does the b.box food jar come with its own cutlery? 

    Yes, each jar includes a clip-in spork that tucks into the custom bumper, so there's no separate cutlery to pack or lose. It clips in securely, which means no loose spoon rattling around the bottom of the school bag. This is built into every jar in the range, not sold separately.

    2. Can kids open the b.box food jar by themselves? 

    Yes, the easy-grip handles give kids enough leverage to open the jar independently from kinder age. A lid stop feature also prevents overtightening, so they're not stuck wrestling with it at lunchtime. This is designed to build independence without needing an adult to step in.

    3. What's the difference between the 335ml and 210ml bbox food jar? 

    The 335ml is the standard size built for primary school kids and fits a full serve of pasta, rice, or soup. The 210ml mini is sized for toddlers and smaller appetites who just need a warm snack-sized portion. Both use the same double-wall vacuum insulation, just scaled to different needs.

    4. How do I get the best heat retention from the food jar? 

    Pre-heat the jar by filling it with hot water for 2 to 3 minutes before adding food. This step dramatically extends how long meals stay warm, especially for soups, curries, and pasta sauces. Liquid-based meals generally hold heat longer than drier foods like rice.

    5. What material is the b.box insulated food jar made from? 

    It's made from 304 food-grade stainless steel, so no plastic ever touches the food inside. It's BPA-free and built to last through daily school use. The double-wall vacuum construction also stops the outside of the jar from sweating, even when packed with hot food.
