ABSTRACT:
A dispenser body and a closure cap assembly for a container is presented which provides not only a closure for the container, except for communication with the dispenser, but also provides an air inlet operable upon the withdrawal or expulsion of the contents of the container so that air will be replenished therein to restore normal air pressure. The air inlet closes automatically when this has been accomplished to prevent leakage of the contents of the container.
