jerrycans

A jerrycan is a robust container designed for the safe transport and storage of liquids, especially fuels. Its distinctive design combines durability, portability, and efficient pouring, making it a staple in military, emergency, and civilian applications. The term originated from Allied slang for the German design used in the mid-20th century, and the format has since been widely adopted and standardized in various forms.

Historically, the jerrycan was developed in the 1930s to address the need for inexpensive, easy-to-transport fuel for military operations. The design emphasizes a sturdy construction, a tight-sealing cap, and a pour-spout that reduces spills during handling and refueling. Although closely associated with German engineering of the era, the concept was quickly adopted by Allied forces and evolved into broader international use, including NATO-standard versions.

The typical jerrycan is a rectangular, pressed metal or plastic container, commonly with a capacity of 20 liters (about 5.3 US gallons). It is usually made from steel or high-density polyethylene and features a secure, gasket-sealed cap and a pouring mechanism that supports controlled dispensing. The container is designed for two or more handles to aid carrying, stacking, and rapid distribution in field conditions, and it is built to withstand rough handling and exposure to the elements.

Common uses include transporting gasoline, diesel, kerosene, and other liquids. While steel and plastic variants exist, all jerrycans require compatibility between the container material and the liquid stored. Modern adaptations have continued to evolve, but the basic form remains widely recognized for its practicality, reliability, and widespread logistical utility.
