poire-poudre is the French term for these powder flasks with a flattened pear shape and straight spout.
Powder flasks were an essential piece of shooting equipment before pre-made paper cartridges became standard in the 19th century. In Europe By the 19th century, stamped metal flasks with a central design in low relief are more common, and standard types by particular manufacturers dominate the field, some produced by gun or powder manufacturers and carrying branding or advertising. The pear shape has become dominant for smaller flasks, which are presumably mostly kept in a pocket
Powder flasks were generally made of non ferrous materials, which can give off sparks when hit, so copper was common.
