The B.Box Insulated 335ml Food Jar in Indigo Rose is a stainless steel food flask built to carry a proper meal to school or day care and keep it at the right temperature until it's time to eat. Whether your child likes warm pasta at lunch or prefers cold fruit and yoghurt, the triple-layer insulation holds the temperature so the food is ready to enjoy when they open it.
With a 335ml capacity, it's sized for a school lunch or a hearty snack, and the design is built around little hands managing it on their own. It's suitable for kids and adults from 3 years and up, making it a practical option if you're looking for a reusable, insulated container that a child can open and close without help.
Made for independent little hands
A lot of the thinking here is about your child managing the jar themselves at the lunch table. The carry handle doubles as leverage, giving small hands something to grip so they can twist the lid open on their own. The smart stop feature stops the lid being overtightened, so it doesn't get sealed shut too firmly to reopen. There's also a spork tucked neatly into the bumper, so the utensil travels with the jar rather than getting lost at the bottom of a school bag.
Easy to personalise and easy to clean
The handles and bumper are removable, so school kids can style the jar to suit themselves. Being able to take the bumper off also makes daily washing more straightforward, and the jar is dishwasher safe on the top rack. It's made from stainless steel, PP and silicone, and is free from BPA.
How it works
- Triple-layer insulation: The layered construction slows heat transfer, keeping food cold for up to 8 hours or warm for up to 6 hours.
- Smart stop lid: A built-in stop prevents the lid from being overtightened, so it stays easy for a child to reopen.
- Easy-fill, leakproof design: The wide opening makes it simple to fill and the lid is designed to stay closed in transit.
- Carry handle for leverage: The handle gives small hands extra grip so they can open the jar independently.
Best For
The B.Box Insulated 335ml Food Jar is a great option for parents who:
- Want to send a warm or cold meal to school or day care and have it hold temperature for hours
- Are looking for a food jar a child aged 3 and up can open and close on their own
- Like an all-in-one option with the spork stored on board
- Prefer a reusable stainless steel container that can be personalised and washed easily
It may not be the best fit if you:
- Need a container you can reheat food in — this jar is not microwave safe
- Are packing very large portions beyond 335ml
Materials and safety
The jar is made using food grade 304 stainless steel. According to B.Box, all products are tested by a global independent testing body to international standards, with test reports confirming no traces of BPA, phthalates, PVC, lead or heavy metals detected.
Disclaimer
The food jar is not microwave safe. It is dishwasher safe on the top rack only. For food safety, follow current guidance on how long particular foods can be kept warm or cold, and discard food that has been returned from your child's mouth rather than saving it.
