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

The method according to claim 3, further comprising: detecting or calculating any one or more parameters of a trolley moving position, a trolley moving speed, a tool horizontal position displacement amount, a tool horizontal position displacement speed, a trolley speed command, a tool reeled height, and a load weight, based on one or a combination of the parameters, building a simulation model comprising at least one of or a combination of the parameters related to the horizontal position displacement of one or more of a mechanism of said crane, driving and control mechanism of said trolley, and said rope, and estimating or calculating the horizontal position displacement of said tool based on the built simulation model. 5. An apparatus for controlling stacking of a load by a crane, said crane having a trolley which moves in a horizontal direction, and a tool which is hung down using a rope from said trolley and which ascends and descends by a reeling or an unreeling operation and which holds a load to be stacked on a stacking target position, said apparatus comprising: a load position control unit which estimates periodical displacement of said tool in a horizontal position and which positions and stops said trolley at a trolley stop position which is deviated from a stacking target position by a distance corresponding to a maximum amplitude of the periodical displacement, and a descending load speed control unit which controls a speed with which said tool descends in such a manner said tool or a load held by said tool lands on the stacking target position when an amplitude of the estimated periodical displacement becomes maximum, and lands said tool or said load. 6.
