A jerrycan or jerrican is a fuel container made from pressed steel. It was designed in Germany in the 1930s for military use to hold 20 litres of fuel, and saw widespread use by both Germany and the Allies during the Second World War.
Stamped indentations stiffen the sides and allow expansion of the contents. Different colours designate the contents.
