I am also puzzled about its utility. A suitable spout, probably of metal, could fit into the aperture on the large end, but that is normally where the filler opening and plug are. And if that were indeed the case, why is there an aperture on the small end, which curls so close to the body that it's difficult to see how it can conveniently access either the pan or the muzzle.
