The present invention is directed to a cover for a container. The cover includes a moveable member and a motor having armature connected to the moveable member. A sensor generates a sensing signal when motion is detected. A controller is connected to the sensor and the motor. The controller receives the sensing signal from the sensor and activates the motor to move the moveable member from a closed position to an opened position. After a predetermined period of time, the controller deactivates the motor to move the moveable member from the opened position to the closed position.
