Abstract
A spout for a jerrycan, characterized by its flexing and telescoping capabilities. The spout consists of a main accordion-like tubular section, with a connector at one end and a nozzle at the other end. The length of the spout can double relative to its retracted condition, wherein it can be forcibly telescopingly extended/retracted, yet will maintain its last chosen extended/retracted condition when the forcible action ceases. The spout main section can be also be flexed, yet will similarly maintain its last chosen flexed condition once this forcible action ceases.
