Abstract: A container with a flexible spout adapted to selectively regulate the flow of liquid therefrom. The spout has a diameter appropriate for being received in an accommodating fill opening such as the oil fill opening of an automobile engine. The spout has an outer portion and a inner portion bendable about a portion of the spout located between the outer portion and inner portion. The bendable portion may be configured as an annular groove extending around the circumference of the spout. The inner portion extends from the top portion of the reservoir. The outer portion extends from the annular groove and terminates at a normally open outlet through which the oil from the container is poured into the oil fill. Threads are provided about the exterior of the outer portion of the spout adjacent the opening to threadedly receive a cap to cover the outlet and close the opening. The annular groove uniformly extends around the circumference of the spout.
