Query: Unsafe device to have in a car

The Hot Pot heats the water pretty weel, but the cap do not close tight, and the hot water can spill out very easy. I only use once, because I need to make some teas, while working outside and sometimes is difficult to find hot water, but I will never use it again and if I had the possibility to return I could do it, but I don't have the box and the packing list, anyways is not too expensive.I would like to know, before I bought it, this trouble with the cap.
