Camelback kids thermos in fridge?

[hillview]

There is no reason I can't keep camelback kids thermos (straw cups -- the metal kind) in the fridge for a couple of days for an easy grab out the door right? Am I missing something?

I've done it - no problems so far. If it's insulated, make sure the liquid is cold before going in. I put room temp juice in a funtainer then put it in the fridge. The juice was still room temp when I took it out!

That's where mine live.
