Abstract
The invention provides an improved ink jet cartridge for an ink jet printer and a method for making the improved ink jet cartridge. The method includes providing a thermoplastic, flexible web having an edge portion, a first side and a second side and providing a substantially inflexible frame member having at least one peripheral edge. Disposing the first side of the flexible web adjacent the peripheral edge of the frame, thereby defining a substantially closed cavity. Heat welding the edge portion of the web and peripheral edge of the frame to one another using a heated platen using a heat welding structure and conditions which minimize thinning of the flexible web on the bonding surface at least adjacent the substantially closed cavity. Minimizing the thinning of the flexible web adjacent the closed cavity substantially improves the weld and resulting reliability of the ink cartridge.
