Today in 1934, US Patent 1950714 A was issued, an invention of Ernest Joseph D’Aoust and Herbert Lawrence Dickens, for their “Container and Cooler.” There’s no Abstract, although in the description it includes this summary:

The invention relates to a container and cooler, as described in the present specification and illustrated in the accompanying drawing that forms part of the same.

The invention consists essentially of the unit combining the means for refrigerating and the container as pointed out in the claim for novelty following a description in detail of the parts making up the unit.

The objects of the invention are to cool liquids such as beer, especially contents being continually drawn upon thereby making it possible to maintain the volume of liquid in constant use in a palatable condition while a considerable volume remains unchilled, which are ideal conditions for dispensing beer and many liquids, especially where they are sold by the glass; to facilitate the transport of beer and some other beverages, particularly those beverages liable to deterioration from changes of temperature and therefore deliver the container with its contents in as fit a state as when it left the brewery, factory or other production centre; to utilize dry ice, artificial ice, natural ice or chemical refrigerants to the best advantage for cooling containers and introduce the cooling medium with ease; and generally to provide for restaurants, hotels, merchants, dwellings and places of entertainment, a convenient form of container from which the beverage will be delivered in a wholesome condition and which will not materially add to the cost of the invention to the consumer.
