I bought this for my husband for Christmas. He works outside and wanted something to keep liquids warm. There is no way to cap this product. I put soup in it, turned it on it's side and it spilled everywhere. It leaks, majorly! If there is any chance this product might end up on it's side, then don't buy it! Needless to say, I sent it back. So now I'm out $15 dollars and have nothing to show for it!
