Collapsible ink reservoir structure and printer ink cartridge. |
摘要 |
<p>A collapsible ink reservoir structure (25) to facilitate assembly of a replaceable or refillable printer ink cartridge is comprised of a relatively rigid frame (20) and flexible membranes (22, 24) forming an ink reservoir having side walls which collapse to a substantially flat shape to minimize the amount of ink remaining in the reservoir structure after computer generated printing has depleted the ink from the cartridge. The structure (25) is a separate unit which is assembled and mounted in an outer housing (10) to form an ink cartridge. The structure preferably contains an ink pressure regulator (30) which maintains a negative pressure therein.</p> |
