Jerry Cans

Jerrycans were designed in 1930s Germany for military use. Jerrycans were designed with three handles as it was specified that a soldier should be able to carry two full containers or four empty ones by holding onto the outer handle, according to Wikipedia. The three handles also come in handy when two people are carrying a jerrycan, with each grabbing one of the outer handles, or when you're grabbing it on you're own and can use the middle handle.
