convert any bottle to a sports bottle? any one know if you can buy tops to put on water bottles?

[overthemill]

many moons ago (about 10 i think) I got a great freebie from something baby related and it was a bottle cap that fitted standard mineral water bottles and it had a sports cap with a flip over lid. it was great but got all chewed up.

I now want to get one for my dd who has to have a see through bottle of water for school that has a sports cap but must be no more than 500ml!!!! The ones with sports caps seem to be 750 or more so i wondered if anyone knew a source?

I have googles but seem to get replacements for actual sports bottels which isn't what i mean

we have loads of metal sports bottles but those tops don't fit...

bump for the afternooon crowd?

I'm sure I've bought sports cap bottles of water smaller than 500ml before in the supermarket, for birthday parties. They might not be big enough for a whole day at school though? Think they were about 300ml.

i have looked and only found fruit shoots smaller but of course they aren't see through (which it needs to be so kids only bring in water). Its a real pain!!

Don't Robinson's do a flavoured water Fruit Shoot now? I'm sure I've seen some and they're the size of the normal bottles but see-through.

ooh will look, ta! Still hoping someone sells the ones i think i remember too!
