I found this while rehabbing a house. It is two and three quarters inches high and two inches across the top. It is unusual in that it has a lip on the inside that goes about halfway to the bottom. It has a screw type top. It has a seam running up each side but it doesn't appear to go through the top. The bottom has a circle with the number 19 and also reads,"PAT.D.1759866". Any help would be appreciated.
Thank you,
Tim
