A container includes a body, a main cap, and an operating set movably inserted into the body. The body has two communicating accommodation areas, a top opening communicating with one of the accommodation areas and covered by the main cap, a partition dividing the other accommodation area into accommodation spaces, and an enclosing wall laterally disposed between the accommodation areas and defining an enclosing opening. The operating set includes a shank, two ends of which respectively formed a head protruding from the main cap and an engagement unit having at least one trough which faces the partition through the enclosing opening. When the engagement unit moves to the partition, the partition is lodged into the trough for placing the engagement unit in position. Therefore, the enclosing opening is sealed to prevent the accommodation areas and the accommodation spaces from communicating with each other and attain a preferable sealing effect.
