That was one time at the beginning of Captain America. People put it in containers to either hide the Tesseract or channel its power into machines. Given how Cosmic Cubes are supposed to be lesser versions of the Reality Stone, odds are weird things happen when people touch it because they subconsciously want it to happen. For instance, when Red Skull picked it up it sent him into a portal. Given the situation, he probably wanted to retreat and it gave him the means to do so.
