Abstract
An inkjet cartridge for use with a thermal inkjet printer includes a free ink chamber with a tube disposed therein, wherein the tube defines therein an entrained ink chamber. The tube can extend from the top of the free ink chamber to the bottom thereof. The tube is preferably laterally enveloped by the free ink chamber. The tube has an interior surface on which a longitudinal channel can be defined, and wherein the channel can be helical.
Claims22
An inkjet cartridge including a free ink chamber and an entrained ink chamber, the inkjet cartridge comprising a tube which defines therein the entrained ink chamber, wherein:
- the tube is disposed within the free ink chamber;
- and
- the tube has an interior surface on which a substantially longitudinal channel is defined.
An inkjet cartridge including a free ink chamber and an entrained ink chamber, the inkjet cartridge comprising:
- a wall that defines the free ink chamber, the wall comprising a top panel and a bottom panel;
- and
- a tube that defines the entrained ink chamber, wherein the tube is disposed within the free ink chamber and extends between the top panel and the bottom panel, and wherein the bottom panel defines therethrough a discharge opening that is substantially circumscribed by the tube.
An inkjet cartridge, comprising:
- a wall that encloses a free ink chamber, wherein the wall defines at least a top panel and bottom panel that are oriented in substantially parallel, spaced-apart, juxtaposed relation to one another
- an elongated tube disposed within the free ink chamber, wherein:
- the tube has a first end that is connected to the top panel;
- and,
- the tube has an opposite distal second end that is connected to the bottom panel.
An inkjet cartridge comprising:
- a wall that encloses a free ink chamber, wherein the wall defines at least a top panel and a bottom panel that are oriented in substantially parallel, spaced-apart, juxtaposed relation to one another;
- and
- an elongated tube disposed within the free ink chamber, wherein:
- the tube has a first end that is connected to the top panel;
- and
- the tube has an opposite second distal end that is connected to the bottom panel;
- and
- the bottom panel defines therethrough a discharge opening that is substantially circumscribed by the tube.
An inkjet cartridge, comprising:
- a wall that encloses a free ink chamber, wherein wall defines at least a top panel and a bottom panel that are oriented in substantially parallel, spaced-apart, juxtaposed relation to one another;
- an elongated tube disposed within the free ink chamber, wherein:
- the tube has a first end that is connected to the top panel;
- the tube has an opposite distal second end that is connected to the bottom panel;
- the top panel defines therethrough a vent opening that is substantially circumscribed by the tube;
- the bottom panel defines therethrough a discharge opening that is substantially circumscribed by the tube;
- the tube defines therethrough an ink port;
- and
- the capillary reticulate material substantially fills the tube and covers the ink port;
- and
- a capillary reticulate material disposed within the tube.
An inkjet cartridge, comprising:
- a wall that encloses a free ink chamber;
- and,
- a tube that has a first end and an opposite distal second end, wherein:
- the tube is disposed within the free ink chamber;
- the first end is connected to the wall;
- and,
- the second end is connected to the wall.
An inkjet cartridge including a free ink chamber and an entrained ink chamber, the inkjet cartridge comprising a tube which defines therein the entrained ink chamber, wherein:
- the tube is disposed within the free ink chamber;
- the tube defines therethrough an ink port;
- and
- the tube has an interior surface on which is defined a substantially helical open channel that intersects the ink port.
