Abstract

A liquid container includes, in a container body 3, an ink containing portion 5, an ink supply portion 7, an ink leading path 9 for leading an ink stored in the ink containing portion 5 to the ink supply portion 7, and an atmosphere communication port 4, and an ink end sensor 11 for detecting an inflow of a gas to the ink leading path 9, thereby detecting that a residual amount of the ink in the ink containing portion 5 is zero is provided in the middle of the ink leading path 9, and furthermore, an air bubble trap passage 13 for catching air bubbles mixed in the ink is provided in the ink leading path 9 between a detecting position of the ink end sensor 11 and the ink containing portion 5.

Description

technical field [0001] The present invention relates to an atmosphere-communicating type liquid container suitable, for example, as an ink cartridge attached to an inkjet printer. Background technique [0002] As an ink cartridge (liquid container) to be attached to an inkjet printer, various atmosphere-communicating type containers have been proposed which include an ink containing portion (liquid containing portion) for containing ink in a container body attached to the printer, a connection An ink supply portion (liquid supply portion) to the print head on the printer side, an ink guide path (liquid guide path) for guiding ink stored in the ink containing portion to the ink supply portion, and an ink containing portion for Consumption of the ink in the medium introduces the atmosphere from the outside to the atmosphere communication port in the ink containing portion. [0003] Furthermore, some ink cartridges are provided with an ink remaining amount detection mechanism ...
