Abstract
Abstract A multi function device, adapted to be employed as a closure member for wide diameter containers by virtue of an outer rim and narrow diameter containers by virtue of an inner rim. The cover surface extends upward and can provide a partial vacuum seal. The cover surface is designed for aerodynamic stability and the device can be thrown with a spinning motion for gliding effects. Also, two of the devices can be combined to form a string wound amusement device.
