Air bag placed in a print cartridge and method for manufacturing the same

摘要

An air bag placed in a print cartridge and a method for manufacturing the same are provided, wherein a layered material with two faces of different ingredients are utilized. After cutting and opening of connection holes and air vent holes, flexible stacking according to the capacity requirement of the air bag and thermal pressuring are performed. Through the characteristic that two low-melting-point ingredients can be affixed together but two high-melting-point ingredients or a low-melting-point ingredient and a high-melting-point ingredient cannot be affixed together, the whole air bag can be integrally formed. The air bag forms a plurality of receiving rooms having connected air vent holes. The air bag can be folded up to make inflation and deflation, hence filling up the ink-storage capacity of the print cartridge. Moreover, the back pressure can be adjusted.
