Printing system structures
View Patent ↗A liquid ink container having mating features for self alignment with an ink delivery station. The ink delivery station includes a receiver with an actuated puncture ring. The liquid ink container includes a cap that is punctured by the ring to allow fluid flow from the container. The receiver and container also include means for introducing pressurized gas into the container to facilitate evacuation of liquid ink.
1. A structure associated with a printing system, the structure comprising:
a liquid ink container, comprising
a receptacle having an inner volume defined therein for holding liquid ink, wherein the receptacle comprises a bottom surface, a top surface opposite the bottom surface, and at least one wall extending from the bottom surface to the top surface, wherein a hole is disposed through the top surface, and wherein the at least one wall comprises one or more inwardly extending notches, and
a cap coupled to the receptacle for sealing the hole, wherein the cap comprises
a puncture seal, and
a gas fitting that is configured to allow pressurized gas into the receptacle; and
an ink delivery station that is configured to support the liquid ink container at an angle wherein the liquid ink flows from the liquid ink container due to the force of gravity, wherein the ink delivery station comprises a support surface having one or more protrusions extending therefrom, and wherein each of the protrusions are configured to mate with a corresponding one of the notches, to prevent movement of the receptacle when a force is exerted on the cap.
2. The structure of claim 1 , wherein the ink delivery station further comprises a receiver that is configured to mate with the cap.
3. The structure of claim 2 , wherein the receiver further comprises a ring that is actuatable to stamp a hole in the puncture seal.
4. The structure of claim 2 , wherein the receiver further comprises a nozzle for the pressurized gas, wherein the nozzle is configured to mate to the gas fitting.
5. The structure of claim 1 , wherein the liquid ink container further comprises a radio frequency identification (RFID) tag coupled to the receptacle, wherein the RFID tag contains information related to the contents of the liquid ink container, and wherein the ink delivery station further comprises a processor coupled with an RFID reader that is configured to read the contents of the liquid ink container stored on the RFID tag.
6. The structure of claim 5 , further comprising:
a display configured to display the contents of the liquid ink container stored on the RFID tag.
7. The structure of claim 1 , wherein the support surface is disposed at an acute angle from the horizon such that the liquid ink container is supported at a downward angle.
8. The structure of claim 1 , wherein the ink delivery station further comprises a processor, wherein the processor is configured for any of
a puncture of the puncture seal, or
an introduction of pressurized gas into the liquid ink container.
9. The structure of claim 1 , wherein the receptacle, including the inner volume, is substantially rigid.
