Embodiment Construction

[0043] The invention discloses a replaceable ink storage container for providing ink to an inkjet printer. The ink reservoir includes a housing defining an ink reservoir, a vent in airflow communication with the ink reservoir, and an ink outlet in ink flow communication with the ink reservoir. The vents provide airflow communication with the ink reservoir.

[0044] The ink outlet provides ink flow communication with the ink reservoir through a guide surface defined by a vertically oriented forward wall of the housing. The ink outlet and vent holes are usually located on different walls of the housing.

[0045] As used herein, the terms printer cartridge, ink cartridge, printer box, and cartridge generally refer to ink storage containers configured for inkjet printers that function as ink cartridges. As used herein, the term "convex" means an outwardly curved or circular structure resembling the exterior of a sphere or circle. As used herein, the term "concave" means an inwa...

Abstract

An ink container includes a housing that defines an ink reservoir, an air vent in air flow communication with the ink reservoir, and an ink outlet in ink flow communication with the ink reservoir. The air vent provides air flow communication between atmosphere and the ink reservoir. The ink outlet provides an ink flow path out of the ink reservoir through a leading surface of the housing. The ink outlet and air vent can be positioned on different sides of the cartridge or on the same side of the housing. The leading surface faces in a generally horizontal direction. The leading surface can include a contoured shape such as a convex shape.

Description

technical field [0001] The present invention relates generally to an ink storage container, and more particularly to a print cartridge for an ink jet printer. Background technique [0002] Inkjet printers are a common form of printer that can be used with computers, as similar applications include document printing or graphics preparation. A typical inkjet printer has replaceable ink cartridges. The different types of ink cartridges all have structures and features that improve the performance and usability of the ink cartridges for a given printer. For example: the type of ink flow and air flow characteristics can change the ink flow characteristics of the ink expelled from the cartridge. One type of ink cartridge includes a sealed ink chamber without an air inlet. The walls of the ink chamber are flexible and are depressed under the vacuum pressure conditions within the ink cartridge that are created when ink flows out of the ink chamber. A biasing force is sometimes a...
