Patent

CA 2169901

A print head having an ink reservoir therein is made by forming, in a one-shot plastic injection molding step, a rigid monolithic frame comprising high melt temperature material having an opening therein extending from a first side to a second side, and first and second bonding surfaces surrounding the opening and facing the first and second sides, respectively. First and second thin flexible films are adhesively secured to the first and second bonding surfaces, respectively. The adhesive material may be a hot melt adhesive or dry adhesive films pre-formed to the shape of the bonding surfaces. By securing the flexible films to the bonding surfaces adhesively, rather than by heat staking, it is not necessary to form the frame of different materials during two separate molding steps.
