Abstract

A cap for a cup includes a piston seat which includes a room, and an aperture is defined through the lower end of the piston seat. An air path communicates with the aperture. A check valve is movably engaged with the lower end of the piston seat and includes a plate which is deformable to control the air path to be opened or closed. A suction device is located in the piston seat and includes a position rod whose lower end is connected to a piston head which is located in the room of the piston seat. The upper end of the piston rod protrudes beyond the top end of the piston seat and is connected to a handle. By pulling and pushing the handle, the air in the cup is sucked out.
