Crown Cork and Seal is famous and still exists to this day thanks to William Painter and his invention. The bottle listed here was originally thought to be a short beer bottle but after further information it more appears to be a pressure testing bottle. The bottle has a hole in the rear and would be pressurized to determine how much pressure the bottle could hold before the Loopseal would fail. The attached advertisement from 1903 shows the line up of their products which included the Crown Cork Seal, Loopseal and Aluminum Stopper.
