Abstract

Abstract An all-plastic ''''Jerry Can'''' is made with a recessed handle and a screw-top opening. A breather tube extends from the highest part of the inside of the can, through the recessed plastic handle, to a point on the upper ledge surface of the single screw-top opening which point is sealed by the cap, when in place. When the cap is removed, air may pass from the exposed end of the breather tube and into the highest part of the can, thereby allowing the gasoline or other fluid to flow smoothly from the can, without surging caused by the successive creation and breaking of a vacuum pocket inside the container.
