Abstract:
A cooler apparatus for an entirely rigid bottle having a top, a neck which increases in diameter down its length, and an end, said cooler apparatus comprising:a lower cylindrical enclosure means comprising an insulating foam material for thermally insulating said rigid bottle and having a closed end and a circular upper rim defining a circular opening into a cylindrical interior for receiving the end of said rigid bottle; an upper enclosure means comprising an insulating foam material for thermally insulating said rigid bottle and having a dome-shaped upper end unitarily and integrally forming into a lower cylindrical section, the lower cylindrical section terminating in a circular rim sized in diameter to telescopically interfit into the interior cylindrical surface of said lower enclosure means; said upper dome-shaped portion including a circular opening means therein sized in diameter to pass over the top of said rigid bottle and come into a locking relation with the neck of said rigid bottle at a selected diameter along said neck, said locking relation preventing further downward progress of said upper dome-shaped portion along said neck, the diameter of said opening means determining the ultimate and final extent to which the lower cylindrical section of said upper enclosure means extends into said lower cylindrical enclosure means; a first thread means located on the inside of said lower cylindrical enclosure means; and a second thread means formed on a lower portion of the exterior surface of said upper enclosure means and extending to a point at least halfway up the side of said upper enclosure means, said first and second thread means cooperating with one another for providing insertion of said upper enclosure means into said lower enclosure means, said insertion continuing until said locking relationship with the neck of said rigid bottle is achieved, said first and second thread means thereafter cooperating for retaining said upper enclosure means located within said lower enclosure means.
