US Patent 8950637 Valved fluid transport container

A fluid flow-control valve is housed within a fluid transport container or vessel. The valve is operated by a trigger actuating a plunger or shaft. The trigger is located in the handgrip space of a pouring handle so as to resiliently provide one-handed control of fluid flow from the vessel. The valve is resiliently biased to a closed state. A telescopically extendable spout is attached to and housed within the main body of the valve and may include an integral breather passageway. When the spout is retracted it locks out the operation of the trigger.
