Abstract

A toner container which includes a main body for storing toner, an opening for dispensing toner, and a mechanism for sealing the opening. The mechanism for sealing the opening includes a slidable shutter which includes a cover and an extension, connected to the cover part, including a pushing surface and a blocking surface. The mechanism for sealing further includes a restriction which contacts the blocking surface to prevent the slidable shutter from sliding.

Claims

1. A toner container for storing toner, comprising:

an opening for dispensing toner; and

a mechanism for sealing the opening, including;

a slidable shutter including;

a cover; and

an extension, connected to the cover, including a pushing surface and a contact portion, the extension being downstream of the cover relative to an opening direction of the shutter, the pushing surface disposed between the contact portion and the cover,

a restriction which contacts the contact portion of the slidable shutter to prevent the slidable shutter from sliding,

wherein;

the pushing surface is to receive a pushing force which causes a flexing of the extension which moves the contact portion such that the restriction does not block the contact portion and does not prevent the slidable shutter from sliding, and

the contact portion of the extension is at an end of the slidable shutter.

2. The toner container according to claim 1, further comprising:

an opening force receiving area which receives a force to open the slidable shutter and is at an end of the slidable shutter which is opposite to the end of the slidable shutter at which the contact portion is located.

3. The toner container according to claim 1, wherein:

the restriction houses a portion of the slidable shutter, when the slidable shutter is in an open position.

4. The toner container according to claim 3, wherein:

the restriction houses the portion of the slidable shutter when the extension is in a flexed position.

5. The toner container according to claim 1, wherein:

the pushing surface includes two angled surfaces which contact each other.

6. The toner container according to claim 1, further comprising:

a cap which includes the opening and the mechanism for sealing the opening.

7. The toner container according to claim 1, further comprising:

a second contact portion and a second restriction to prevent the slidable shutter from sliding.

8. The toner container according to claim 1, further comprising:

a main body which includes the toner.

9. A toner dispensing system, comprising:

a container holder including a biasing portion; and

a toner container which comprises;

an opening for dispensing toner; and

a mechanism for sealing the opening, including;

a slidable shutter including;

a cover, and

an extension, connected to the cover, including a pushing surface and a contact portion, the extension being downstream of the cover relative to an opening direction of the shutter, the pushing surface disposed between the contact portion and the cover; and

a restriction which contacts the contact portion of the slidable shutter to prevent the slidable shutter from sliding,

wherein;

the pushing surface is to receive a pushing force which causes a flexing of the extension which moves the contact portion such that the restriction does not block the contact portion and does not prevent the slidable shutter from sliding, and

the contact portion of the extension is at an end of the slidable shutter.

10. The toner dispensing system according to claim 9, wherein:

the contact portion of the extension is at an end of the slidable shutter.

11. The toner dispensing system according to claim 9, further comprising:

an opening force receiving area which receives a force to open the slidable shutter and is at an end of the slidable shutter which is opposite to the end of the slidable shutter at which the contact portion is located.

12. The toner dispensing system according to claim 9, wherein:

the restriction houses a portion of the slidable shutter, when the slidable shutter is in an open position.

13. The toner dispensing system according to claim 12, wherein:

the restriction houses the portion of the slidable shutter when the extension is in a flexed position.

14. The toner dispensing system according to claim 9, wherein:

the pushing surface includes two angled surfaces which contact each other.

15. The toner dispensing system according to claim 9, further comprising:

a cap which includes the opening and the mechanism for sealing the opening.

16. The toner dispensing system according to claim 9, further comprising:

a main body which includes the toner.

17. A toner container for storing toner, comprising:

an opening for dispensing toner; and

a mechanism for sealing the opening, including;

a slidable shutter including;

a cover; and

an extension, connected to the cover, including a pushing surface and a contact portion, the extension being downstream of the cover relative to an opening direction of the shutter,

a restriction which contacts the contact portion of the slidable shutter to prevent the slidable shutter from sliding,

wherein;

the pushing surface is to receive a pushing force which moves the contact portion upward such that the restriction does not block the contact portion and does not prevent the slidable shutter from sliding, and

the contact portion of the extension is at an end of the slidable shutter.

18. The toner container according to claim 17, further comprising:

an opening force receiving area which receives a force to open the slidable shutter and is at an end of the slidable shutter which is opposite to the end of the slidable shutter at which the contact portion is located.

19. The toner container according to claim 17, wherein:

the restriction houses a portion of the slidable shutter, when the slidable shutter is in an open position.

20. The toner container according to claim 19, wherein:

the restriction houses the portion of the slidable shutter when the extension is in a flexed position.

21. The toner container according to claim 17, wherein:

the pushing surface includes two angled surfaces which contact each other.

22. The toner container according to claim 17, further comprising:

a cap which includes the opening and the mechanism for sealing the opening.

23. The toner container according to claim 17, further comprising:

a second contact portion and a second restriction to prevent the slidable shutter from sliding.

24. The toner container according to claim 17, further comprising:

a main body which includes the toner.
