Print media and ink supply cartridge
View Patent ↗A print media and ink supply cartridge includes a base molding and a cover molding between which there is located a deformable film. Ink is stored in a deformable volume between the deformable film and the cover molding. A number of ink outlet nozzles, which communicate with the deformable volume are formed into the cover molding whereas air inlets are formed into the base molding. Pierceable seals cover the ink nozzles and are pierced upon coupling of the cartridge to a printer. The cartridge is arranged so that the nozzles are located clear of the cartridge's print media housing in order that the nozzles are readily accessible to the printer.

an ink chamber base molding;
an ink chamber cover molding, the base molding and cover molding together defining a plurality of separate ink chambers;
a deformable member disposed between the base molding and top molding, the deformable member including a deformable wall for each of said ink chambers, the deformable wall dividing each ink chamber thereby defining a deformable first volume and a deformable second volume, the first volume providing a deformable ink storage volume for each ink chamber;
for each ink chamber, one or more outlets from said ink storage volume; and
for each ink chamber, one or more air inlets into said second volume.
2. A print media and ink supply cartridge according to claim 1 , wherein the one or more outlets comprise nozzles formed in the cover molding.
3. A print media and ink supply cartridge according to claim 2 , including pierceable ink seals located to seal the nozzles.
4. A print media and ink supply cartridge according to claim 2 , wherein a region of the cover molding supporting the nozzles extends beyond a paper storage portion of said cartridge.
5. A print media and ink supply cartridge according to claim 1 , wherein the ink chamber base molding, ink chamber cover molding and the deformable member are configured to provide a number of distinct ink chambers to store different inks.
6. A print media and ink storage cartridge according to claim 1 wherein said deformable member is retained by and between said base molding and said cover molding.
