Ink cartridge and method of producing the same

摘要

An ink cartridge includes a cartridge body defining an ink chamber, an ink supply portion provided at the cartridge body, an air flow path provided in the cartridge body, a cover, and a memory chip disposed on the cover. The cartridge body has an outer surface oriented in a first direction and an air communication port opened on the outer surface. The air flow path communicates with the ink chamber through a communication hole and with ambient air through the air communication port to permit communication between the ink chamber and ambient air. The cover covers the outer surface of the cartridge body and has an opening at a position aligned with the air communication port in the first direction. The memory chip closes the opening and stores information. External access to the memory chip permits information to be electrically retrieved therefrom.

1. An ink cartridge comprising:
a cartridge body defining an ink chamber therein for storing ink, the cartridge body having a first outer surface and an air communication port formed to be open on the first outer surface, the first outer surface being oriented in a first direction; an ink supply portion provided at the cartridge body and configured to supply the ink stored in the ink chamber to outside; an air flow path provided in the cartridge body, the air flow path being configured to be in communication with the ink chamber through a communication hole and in communication with ambient air through the air communication port to permit the ink chamber to communicate with ambient air through the air flow path; a cover covering the first outer surface of the cartridge body, the cover being formed with an opening at a position aligned with the air communication port in the first direction, the air communication port being positioned to be spaced away from the opening in the first direction to define a gap therebetween, the gap being in communication with a space formed between the cartridge body and the cover; and a memory chip disposed on the cover to close the opening and configured to store information, external access to the memory chip permitting the information to be electrically retrieved therefrom.
