I put the thermos in the outside elastic pocket of my backpack. In Charlotte, I took it out, removed the cap and laid it next to my laptop. No problem. On the way home yesterday from Heathrow, the lady assisting everyone with security simply asked if it was empty, I said yes, and she left it in the pocket and sent the whole thing through x-ray. I saw a LOT of people sending drinking cups and thermoses through with their children's luggage, so I didn't feel as nervous as I would have..
