Abstract

A device to supply printing material to a printing material container of a printing apparatus includes a container including a plunger and to contain the printing material, a portal couplable to a refill port to the printing material container. The portal includes a discharge port through which the printing material is transferrable from the container, and a connector to receive power to move the plunger, to cause a transfer of the printing material contained in the container to the printing material container through the discharge port.

First claim

What is claimed is:

1. A device to supply printing material to a printing material container of a printing apparatus, the device comprising:
a container including a plunger and to contain the printing material;
a portal couplable to a refill port to the printing material container, the portal including
a discharge port through which the printing material is transferrable from the container, and
a connector to receive power to move the plunger, to cause a transfer of the printing material contained in the container to the printing material container through the discharge port.

2. The device of claim 1 , further comprising:
a shaft rotatable to move the plunger toward the discharge port, to cause the transfer of the printing material.

3. The device of claim 2 , wherein
the shaft includes an engaging portion to engage the plunger, and
the plunger is to engage with the engaging portion to be movable by rotating of the shaft along the engaging portion, to cause the transfer of the printing material.

4. The device of claim 2 , wherein the container includes an agitator to rotate along with rotating of the shaft to move printing material around the agitator in the container.

5. The device of claim 4 , wherein the agitator is deformable by the plunger moving toward the discharge port.

6. The device of claim 2 , wherein the shaft includes a sifting flange disposed adjacent to the discharge port, the sifting flange to rotate along with the shaft to sift the printing material toward the discharge port.

7. The device of claim 2 , wherein the connector includes a first gear to contact a second gear disposed at the refill port to engage with the second gear, to be rotatable by the second gear receiving the power, to rotate the shaft to move the plunger.

8. The device of claim 1 , wherein the plunger is movable based on an amount of printing material contained in the printing material container.

9. The device of claim 1 , further comprising:
a locking structure including
a first locking piece having a first portion of the discharge port, and
a second locking piece having a second portion of the discharge port,

wherein at least one among the first locking piece and the second locking piece is movable to connect the first portion and the second portion to form an opening of the discharge port and to disconnect the first portion from the second portion to close the opening of the discharge port.

10. A printing apparatus to include a printing material container coupleable to a device, the printing apparatus comprising:
a refill port through which the device including printing material is couplable to the printing material container and to receive power to drive the device to supply the printing material included in the device to the printing material container.

11. The printing apparatus of claim 10 , wherein the refill port includes a power transference medium through which the device is to receive the power to drive the device.

12. The printing apparatus of claim 11 , further comprising:
a power supply to supply the power to the device through the power transference medium to drive the device to supply printing material to the printing material container.

13. The printing apparatus of claim 12 , wherein
the device includes a first gear rotatable to deliver power to drive the device to supply printing material to the printing material container, and
the power transference medium includes a second gear to contact the first gear through the refill port to engage with the first gear to supply the power.

14. The printing apparatus of claim 10 , further comprising:
a controller to meter an amount of printing material in the printing cartridge.

15. The printing apparatus of claim 14 , wherein the controller is to meter the amount of printing material in the device.
