b.box drink bottles are built for one job: getting kids to actually drink enough water, without the leaks. From the everyday b.box Drink Bottle to the double-walled b.box Insulated Drink Bottle and the big-capacity b.box Insulated Flip Top Drink Bottle, every design uses b.box's signature spill-proof spout — so bags, backpacks and car seats stay dry.
Shop the Full b.box Drink Bottle Range
b.box Drink Bottle (450mL & 600mL): The everyday school bottle. Lightweight, BPA-free and fitted with a flip-top, bite-and-sip spout that's easy for little mouths to use and genuinely leak-proof in the bag.
b.box Insulated Drink Bottle (500mL): Double-walled stainless steel keeps water cold for hours, even on hot Aussie days. Same easy-sip spout, with the added bonus of a bottle that won't sweat all over their lunchbox.
b.box Insulated Flip Top Drink Bottle (1L): A bigger, insulated option for older kids, sport, or anyone who needs more water to get through the day. The flip-top lid opens one-handed and locks flat for a clean seal.
b.box Cleaning Brush Sets: Purpose-built brushes to reach every straw and spout, so bottles stay properly clean and fresh — not just rinsed.
Why Aussie Parents Choose b.box Drink Bottles
Genuinely Leak-Proof: The flip-top spout seals tight and is tested to stay dry even upside down in a schoolbag — no more soggy lunchboxes or wet library books.
Easy for Little Hands: One-handed flip lids and a soft, bite-resistant spout mean kids can open, drink and reseal their own bottle from an early age.
BPA-Free & Built to Last: Free from BPA, PVC and phthalates, and tough enough to survive daily drops in and out of a school bag.
A Size for Every Age: From a 450mL bottle for preschoolers to a 1L insulated option for older kids and sport, there's a b.box bottle sized to the day ahead.
Frequently Asked Questions
Are b.box drink bottles leak-proof?
Yes — the flip-top spout is designed to seal tightly and stay leak-proof even when the bottle is upside down in a bag, as long as the lid is clicked fully closed.
What's the difference between the Drink Bottle and the Insulated Drink Bottle?
The standard b.box Drink Bottle (450mL/600mL) is a lightweight everyday bottle, while the Insulated Drink Bottle (500mL) has double-walled stainless steel that keeps water cold for hours — ideal for hot days or sport.
What size b.box drink bottle should I get for my child?
The 450mL suits younger kids or shorter days, the 600mL and 500mL insulated options suit most primary schoolers, and the 1L Insulated Flip Top Drink Bottle is best for older kids, sport, or longer days needing more water.
Are b.box drink bottles dishwasher safe?
Yes, b.box drink bottles are dishwasher safe (top rack recommended for the spout and lid). A dedicated cleaning brush also helps keep the straw and spout properly fresh between washes.
Can I buy spare parts for my b.box drink bottle?
Yes — we stock replacement lids, spouts, straws and seals, so you don't need to replace the whole bottle if one part wears out or goes missing.
