A container assembly includes a cover cap mounted sealingly on a container. The cap has a pump-mounting wall portion defining a pump-receiving chamber, an inlet formed in the pump-mounting wall portion and in fluid communication with the chamber and a storing space of the container, and a valve-mounting wall portion defining an opening which is in the fluid communication with the storing space and the atmosphere. A pump member is disposed movably and sealingly in the chamber, and has an outlet in fluid communication with the chamber and the atmosphere. An urging member urges the pump member away from the inlet. First and second check valves are mounted respectively on the cap and the pump member for closing the inlet and the outlet of the chamber, respectively. An air-inlet valve is mounted on the valve-mounting wall portion for closing the opening in the cap, and is operable to uncover the opening in the cap.
