Title: Vent for an ink-jet print cartridge

Abstract: An ink-jet print cartridge includes a body with a lid. The body defines a vent structure communicating between ambient and an ink reservoir internally of the body. One embodiment of the vent structure includes a straight cylindrical bore opening through the lid of the print cartridge body between ambient and the ink reservoir. This vent structure includes a tapered annular surface surrounding the opening of the straight cylindrical bore on a surface of the lid, so as to direct ink away from the opening of the bore. An annular ink well surrounds the tapered annular surface so as to catch and hold ink flowing along this surface away from the opening of the straight cylindrical bore.
