Abstract
A container assembly with a closure and the structure of the closure. The container has multiple compartments for holding different materials. The container has a closure with a fitment that attaches to the container. The fitment has separate bottom receptacle areas on one side and a top receptacle on the other. The separate receptacle areas are each exposed to different compartments within the container. The top receptacle area is connected to each of the separate receptacle areas by conduits. A selection head is provided having a pour spout and a plurality of baffle chambers. The pour spout has an open central conduit, wherein only some of the baffle chambers are open to that central conduit. The baffle chambers are received within the top receptacle area of the fitment. Different combinations of the baffle chambers selectively align with different conduits as the selection head rotates within the fitment.
