A container assembly includes a cover cap (3) mounted detachably and sealingly on a container (2). The cover cap (3) has a pump-mounting wall portion (34) defining a pump-receiving chamber (45), an inlet (343) formed in the pump-mounting wall portion (34) and in fluid communication with the pump-receiving chamber (45) and a storing space (23) of the container (2), and a valve-mounting wall portion (35) defining an opening (350) which is in fluid communication with the storing space (23) and the atmosphere. A pump member (4) is disposed movably and sealingly in the pump-receiving chamber (45), and has an outlet (411) in fluid communication with the pump-receiving chamber (45) and the atmosphere. An urging member (42) urges the pump member (4) away from the inlet (343). First and second check valves (31, 43) are respectively mounted on the cover cap (3) and the pump member (4) for closing the inlet (343) and the outlet (411) of the pump-receiving chamber (45), respectively. An air-inlet valve (32) is mounted on the cover cap (3) for closing the opening (350) in the cover cap, and is operable to uncover the opening (350) in the cover cap (3). <IMAGE>
