Mr. Geddie explained:
The objectives of the present invention are accomplished by providing a rigid hat that may be adjusted to fit different size heads such, for example, as a safety helmet or hard hat with an adjustable head band provided therein. Several drink containers are mounted on the sides of the hat using elastic bands that are inserted through slots in the hat and fastened to the inside of the hat. In the illustrated embodiment there are six such containers, including two relatively large containers that might be used for soft drinks such, for example, as soda or ginger ale. The other four containers are relatively smaller and might be used to hold one or more alcoholic beverages. Each drink container is provided with a tube for carrying liquid from the container to one of two gang valves on the front of the hat that may be used for mixing drinks from two or more drink containers. Alternatively, a user of the portable bar may drink from any one container by opening the valve controlling the flow of liquid from that container and closing the valves that control the flow of liquid from all of the other drink containers.
