Abstract: A container assembly comprising two composite packages fastened together for packaging and shipping, but separable for individual use at a retail location. Each package includes an outer paperboard carton and a plastic bottle contained therein, the liquid in the bottle being pourable without removing the bottle from the carton The carton is rectangular and includes front, rear and side walls and a closure flap assembly at its upper end including first and second side flaps connected to and folded substantially perpendicular to said side walls. The edges of the side flaps are shaped to form a first opening for the spout and a second opening defining a handle. The flap assembly also has front and rear flaps which fold over the side flaps and have edges which lie adjacent each other. The front flap has a third opening which aligns with the first opening to accommodate the spout, and the rear flap has a perforated section which aligns with the second opening to form the handle.
