Nothing is more annoying than a leaky water bottle or lunch box, right? Fortunately, this blog is here to help you get started and offer some tips.
The most leak-proof choice is a water bottle with a full screw-top system and a lunchbox with separate, tightly sealing compartments. Also, look for a closure that your child can open themselves, but that stays firmly closed at the bottom of the school bag. Stainless steel lasts the longest and also keeps drinks cool for hours.

Why does a water bottle or lunchbox actually leak?
It's usually due to the closure. A cheerful flap or a pop-up spout is handy at the table, but it gives way a little more easily when the bottle is lying on its side in a full school bag. With lunchboxes, it's often the lid that doesn't seal all around, allowing a wet slice of cucumber or a tasty yogurt to find its way to the notebooks.
The solution is not complicated: choose a system that really closes tightly, and teach your child to place the bottle upright in the bag. That saves a lot of wet sandwiches.

Which water bottle doesn't leak?
A bottle with a screw cap that you tighten completely is the safest choice for a school bag. Such a cap seals all around, whereas a flap or drinking spout always carries a small risk. If you still need a spout for on the go, choose one with a click lock that snaps over it.
Preferably choose stainless steel. Such a bottle is sturdy, doesn't leave an aftertaste, and keeps water or juice fresh for an entire school day. The insulated bottles from 24Bottles are a great example of this: leak-proof, lightweight, and made to last for years instead of just one school year.

Which lunchbox doesn't leak?
For a lunchbox, it's all about separate compartments that each seal well, the bento principle. Wet and dry items stay separated, and nothing spills from one compartment to another. A lid that clicks all around or closes with a sturdy clamp keeps everything in place, even if the box ends up upside down for a moment.
Also make sure that the box fits in the school bag next to the bottle, and that your child can open and close it themselves. A lunchbox that only mom or dad can open will likely come back unopened after school or a day at camp.
What else do you look for with children?
A few things make a daily difference:
- Choose a closure that small hands can operate themselves, but that is sturdy enough to stay closed in the bag.
- Go for material that can withstand a knock and is easy to clean. A wide opening and as few corners as possible where dirt can get in, will save you a lot of washing up in the evening.
- A size that matches your child's age and hunger/thirst. For a toddler, a smaller 300ml water bottle is sufficient; an older schoolchild drinks a lot more, so it's best to give them a larger water bottle.
- Materials without nasty substances are most popular with everyone, such as stainless steel and food-grade plastic.
