The present invention relates to a volume variable container, which comprises a container body (1) and a cover component. The cover component comprises a tubular telescopic body (2) and a cover body (3). The tubular telescopic body (2) is arranged in the container body (1) and an upper end thereof is arranged at a container opening, a sealing part (7) is arranged on a periphery of a lower end thereof, and the sealing part (7) is tightly connected to an inner wall of the container body (1). The cover body (3) is matched with an inner periphery of the lower end of the tubular telescopic body (2). An air vent (6) and a knob (5) arranged beside the air vent (6) are arranged on the cover body (3). The air vent (6) can be opened or closed by rotating the knob (5). The present invention has advantages that a size of the tubular telescopic body can be changed according to a number of contained objects to reduce air in the container body, so that damping of objects in the container body or chemical reaction with the air can be reduced or retarded. |
