Abstract
A container assembly that is adapted to retain an amount of dry ice therein and be disposed within a cooler as a cooling source is provided. The container assembly includes a base and a lid assembly that seal together to provide an inner space to receive the dry ice. The container also includes an attached valve assembly and an outlet hose. The valve assembly is disposed on a side surface of the container to allow for an outflow of carbon dioxide gas produced by the dry ice within the container assembly. The hose is attached to the valve and fastened at its end to an inside surface of the cooler providing a flow of cold carbon dioxide gas to the interior of the cooler as the dry ice sublimates.
