Refillable bottle for Packed lunches

Smallest I've seen are the Systema bottles 330ml. When buying a new lunch box one of the essential features has always been 'will the water bottle fit into it?'. Buy a bigger lunch bag!

Could you ask the school if it's possible to have jugs of water and cups available for the packed lunch children, they should already be providing them for school dinner children. A lot of children that I know, that take packed lunches don't need to bring a drink as water is provided.

Systema does a lunch box that has a flat 200 ml water bottle that fits into one of its sections. I think I got it in Sainsbury’s.

I re-use small plastic bottles from drinks/water. I've tried lots of bottles and very few of them are any good – they leak, crack, have a rubber seal that falls out, or they're expensive and then get lost. A bogstandard smoothie bottle or spout-top mineral water bottle tends to last longer than most "re-usable" ones. Of course they need replacing eventually, but so do the proper ones.

Probably not helpful as I'm guessing it's too big, but I use this short wider one. The lid even doubles as a cup!

A little Sigg bottle might fit. The metal ones last forever - I use one daily that I bought nearly 20 years ago

Chilly's bottles are great though. They keep my tea hot (or my water cold depending on the season) all day

This sistema one has a neat little bottle with it which fits in one of the compartments. The only thing I'll suggest is not putting it in the dishwasher, as after about 6 weeks of dishwashers DDs one cracked.

Sistema bottles are everywhere but I don't think they last that long. I agree with previous poster that Sigg last forever but they are expensive so you would not want your child to lose it! My son in Y3 has lost about 5 bottles. The irony of them being reusable!

I use the SHO bottles in the 260ml size for their lunch boxes. They are brilliant. They're leak proof, keep drinks cold for 24 hours and hot for 12.

I have these ones although they are 300ml they are small.

Sorry posted too soon. They are about the same size as a Fruit Shoot bottle.
