Abstract (en)

A method for manufacturing an ink cartridge includes the step of connecting a film or a pair of films to a frame. The films and the frame define an ink chamber therein, and the ink cartridge includes the films and the frame. The method also includes the step of positioning a patterned member adjacent to the films. The patterned member includes a first pattern, and the first pattern includes a first portion and a second portion which is raised with respect to the first portion. Moreover, the method includes the step of forming a second pattern corresponding to the first pattern on the films by generating a pressure differential between a pressure inside the ink chamber and a pressure outside the ink chamber, in which the pressure differential draws the films into contact with the first pattern.
