Abstract

A toner container for use in an image forming device according to one example embodiment includes a body having a reservoir for holding toner, a toner port on the body in fluid communication with the reservoir, and a shutter translatable along a first dimension between a closed position blocking the toner port and an open position unblocking the toner port. A lock is translatable along a second dimension orthogonal to the first dimension between a locked position blocking the shutter from moving from the closed position to the open position and an unlocked position unblocking the shutter permitting the shutter to move from the closed position to the open position.

Claims (37)

1. A toner container for use in an image forming device, comprising:

a body having a reservoir for holding toner;

a toner port on the body in fluid communication with the reservoir;

a shutter translatable along a first dimension between a closed position blocking the toner port and an open position unblocking the toner port; and

a lock translatable along a second dimension orthogonal to the first dimension between a locked position blocking the shutter from moving from the closed position to the open position and an unlocked position unblocking the shutter permitting the shutter to move from the closed position to the open position.

2. The toner container of claim 1 , wherein the first dimension is a horizontal dimension, and the second dimension is a vertical dimension.

3. The toner container of claim 2 , wherein the lock moves upward when the lock moves from the locked position to the unlocked position, and the lock moves downward when the lock moves from the unlocked position to the locked position.

4. The toner container of claim 1 , wherein the lock includes a locking arm having a blocking surface, the locking arm is movable between the locked position where the blocking surface is positioned in a path of the shutter blocking the shutter from moving from the closed position to the open position and the unlocked position where the blocking surface is positioned clear from the path of the shutter permitting the shutter to move from the closed position to the open position.

5. The toner container of claim 4 , wherein the locking arm is spaced from the shutter when the lock is in the unlocked position and the shutter is in the open position.

6. The toner container of claim 4 , wherein the locking arm contacts the shutter when the lock is in the unlocked position and the shutter is in the open position.

7. The toner container of claim 4 , wherein the lock includes a camming surface positioned to receive a force from a corresponding surface in the image forming device that causes the lock to move from the locked position to the unlocked position during installation of the toner container into the image forming device.

8. A toner container for use in an image forming device, comprising:

a body having a reservoir for holding toner;

a toner port on the body in fluid communication with the reservoir;

a shutter translatable along a horizontal dimension between a closed position blocking the toner port and an open position unblocking the toner port; and

a lock movable upward and downward between a locked position blocking the shutter from moving from the closed position to the open position and an unlocked position permitting the shutter to move from the closed position to the open position.

9. The toner container of claim 8 , wherein the lock is translatable upward and downward between the locked position and the unlocked position.

10. The toner container of claim 9 , wherein the lock moves upward when the lock moves from the locked position to the unlocked position, and the lock moves downward when the lock moves from the unlocked position to the locked position.

11. The toner container of claim 9 , wherein the lock is translatable along a vertical dimension orthogonal to the horizontal dimension.

12. The toner container of claim 8 , wherein the lock includes a locking arm having a blocking surface, the locking arm is movable between the locked position where the blocking surface is positioned in a path of the shutter blocking the shutter from moving from the closed position to the open position and the unlocked position where the blocking surface is positioned clear from the path of the shutter permitting the shutter to move from the closed position to the open position.

13. The toner container of claim 12 , wherein the locking arm is spaced from the shutter when the lock is in the unlocked position and the shutter is in the open position.

14. The toner container of claim 12 , wherein the locking arm contacts the shutter when the lock is in the unlocked position and the shutter is in the open position.

15. The toner container of claim 12 , wherein the lock includes a camming surface for contacting a corresponding surface in the image forming device during insertion of the toner container into the image forming device and receiving an actuation force from the corresponding surface in the image forming device to move the lock from the locked position to the unlocked position.

16. A toner container for use in an image forming device, comprising:

a body having a top, a bottom, a first side and a second side positioned between a first longitudinal end and a second longitudinal end of the body, a longitudinal dimension of the toner container that is orthogonal to a vertical dimension of the toner container extends between the first longitudinal end of the body and the second longitudinal end of the body, the first longitudinal end of the body leads during insertion of the toner container into the image forming device and the second longitudinal end of the body trails during insertion of the toner container into the image forming device, the body has a reservoir for holding toner;

an outlet port on the bottom of the body for exiting toner from the reservoir;

a shutter movable along the longitudinal dimension of the body between a closed position blocking the outlet port and an open position unblocking the outlet port, the shutter moves in a direction away from the first longitudinal end of the body and toward the second longitudinal end of the body when the shutter moves from the closed position to the open position and the shutter moves in a direction away from the second longitudinal end of the body and toward the first longitudinal end of the body when the shutter moves from the open position to the closed position; and

a lock positioned on the first side of the body and movable along the vertical dimension of the body between a locked position blocking the shutter from moving from the closed position to the open position and an unlocked position permitting the shutter to move from the closed position to the open position.

17. The toner container of claim 16 , wherein the lock is translatable along the vertical dimension of the body between the locked position and the unlocked position.

18. The toner container of claim 17 , wherein the shutter is translatable along the longitudinal dimension of the body between the closed position and the open position.

19. The toner container of claim 16 , wherein the lock moves upward when the lock moves from the locked position to the unlocked position, and the lock moves downward when the lock moves from the unlocked position to the locked position.

20. The toner container of claim 16 , wherein the lock includes a locking arm having a blocking surface, the locking arm is movable between the locked position where the blocking surface is positioned in a path of the shutter blocking the shutter from moving from the closed position to the open position and the unlocked position where the blocking surface is positioned clear from the path of the shutter permitting the shutter to move from the closed position to the open position.

21. The toner container of claim 20 , wherein the locking arm is spaced from the shutter when the lock is in the unlocked position and the shutter is in the open position.

22. The toner container of claim 20 , wherein the locking arm contacts the shutter when the lock is in the unlocked position and the shutter is in the open position.

23. The toner container of claim 20 , wherein the lock includes a camming surface for contacting a corresponding surface in the image forming device during insertion of the toner container into the image forming device and receiving an actuation force from the corresponding surface in the image forming device to move the lock from the locked position to the unlocked position.

24. The toner container of claim 23 , wherein the camming surface is positioned on an engagement arm of the lock spaced apart from the locking arm.

25. The toner container of claim 24 , wherein the engagement arm and the locking arm extend downward from the lock.
