Abstract
A container is provided with two chambers, each with a mechanism for expressing its contents toward an outlet neck. The neck mounts a captive cap with an opening through its end wall. A web which longitudinally divides the outlet neck, has an outer tip which is positioned to clean out and close the cap opening as a collar which encircles the captive cap is rotated to axially move the captive cap further onto the container. Rotation of the collar in the angularly opposite sense axially projects the cap so that container contents moving out the neck in the individual lumens can mix where the lumens merge and flow out together through the captive cap outer end opening.
