Abstract
An insulating device for keeping a container of liquid from losing its thermal content to its environment that can double as a recreational throwing toy. The device is constructed of two open-ended cylinder bodies, one inside the other. The inner cylinder 8 of an insulating material for the purpose of keeping a container of liquid cold (or warm) is adhered to the inner side of the outer cylinder 10 of a stiff, yet flexible plastic composite that provides aerodynamic stability and durability. A uniformly weighted ring 2 encircles the forward end of the device sandwiched between the two cylinders, thus providing a forward center of gravity that produces stability in flight. The forward edge 6 of the device is rounded for durability and aerodynamics, while the rear edge 4 is rounded and slightly tapered to reduce drag while in flight. The device, when propelled through the air and provided with a rotation about its horizontal axis will fly in a smooth and calculatable manner. The device, when slipped over a cylindrical beverage container will provide an insulating property for keeping the liquid within at a desirable temperature.
