5-gallon water

A 5-gallon plastic water thermos is a large insulated container designed to keep water or other beverages hot or cold for an extended period of time. The thermos typically has a double-wall vacuum insulation that helps to maintain the temperature of the liquid inside. It often comes with a screw-on lid that features a spout or a handle for easy pouring, and may also have a handle for carrying. The thermos is made of plastic and may also feature additional features such as a built-in cup or a carrying strap.
