A container system comprising an outer container, an inner container and a spout. The outer container includes a body and an outer spout. The inner container includes a bag and an inner spout. The inner container is positionable within the outer container such that the inner spout can extend through the outer spout. The spout interfacing assembly comprises a gasket and a lock ring. The gasket includes an outer container interfacing surface engagable with the outer spout and an inner container interfacing surface engagable with the inner spout. The lock ring is couplable to one of the inner spout and outer spout, the lock ring capable of limiting the movement of the inner spout relative to the outer spout. The attachment of a valve assembly substantially uniformly compresses the gasket to, in turn, maintain a substantially uniform and fluid tight seal between the inner spout and the outer spout.
