Definitions
- the invention relates to a toner cartridge with a hollow cylindrical Main body rotating around its longitudinal axis is drivable and an outlet opening on one of its end faces for toner with a smaller diameter than the main body having.
- Such toner cartridges are both for copiers and for Fax machines and printers are well known. You will with the end with the outlet opening horizontally into the device used and driven in rotation, taking toner powder discharge into the device through the outlet opening. Because the outlet opening has a smaller diameter than the main body, the problem with these cartridges is always when the cartridge is increasingly empty, remove the residual toner from the To convey the outlet opening.
- Solutions have been proposed such as helical Transport wing in the area of the outlet opening containing the toner powder from the circumference of the hollow cylindrical main body to the outlet opening transport there. The previously known solutions are, however, only partially satisfactory and / or satisfactory relatively complex to manufacture.
- the present invention is based on the object To improve the toner cartridge of the type mentioned at the beginning, that a complete emptying of the toner content is possible.
- the object is achieved in that inside the main body has an at least substantially frustoconical shape hollow inner body is arranged, the end smaller diameter in the outlet opening of the main body opens and the end of the larger diameter with that of the outlet opening opposite face of the main body is connected, the inner body in the region of its end larger diameter has a recess in its wall and the main body on its inner surface a spiral Has rib or groove that when the cartridge is rotating conveys the toner to the recess of the inner body, and the inner body on its inner surface with a spiral Rib or groove is provided which the rotating cartridge Toner is conveyed from the recess to the outlet opening.
- the spiral rib or groove of the main body thus conveyed first the toner away from the outlet opening onto the recess of the inner body too.
- This transportation process is independent of the filling level of the cartridge.
- the radial one The recess can preferably extend over half the circumference the end of the larger diameter of the inner body. This ensures that there is always sufficient toner Quantity from inside the cartridge to the outlet opening is transported there.
- the cartridge according to the invention is
- the spiral ribs or grooves of the main body and the inner body are the same Have pitch. It is then guaranteed that there will be none Congestion of the toner in certain areas of the cartridge can come. Rather, the toner becomes uniform at first along the circumference of the main body for the recess in the inner body and then along the inner wall of the inner body transported to the outlet opening.
- the main body can with its end provided with the outlet opening in a known manner Way in a recording of a copier, fax machine or printer can be used, which with a on the scope of Main body attacking tooth profile is provided and Main body drives rotating.
- the outlet opening can also be closed by means of a cover which is located at Inserting the cartridge into the holder opens automatically. This will prevent the toner from falling out when inserting the Cartridge reliably prevented in the device.
- the only figure shows a central longitudinal section through a toner cartridge 10 having a hollow cylindrical main body 11 has.
- the main body 11 is on an end face 12 provided with a central outlet opening 13 which is smaller Diameter than the main body 11 and through the toner in the cartridge 10 is discharged.
- the end of the main body 11 with the discharge opening 13 is in a receptacle 14 of a device, not shown, for example, a copier used.
- the recording 14 has a tooth profile 15, which on the circumference of the main body 11 attacks and with the help of the cartridge 10 in the direction of the arrow 16 can be driven in rotation.
- a frustoconical hollow inner body 17 Inside the main body 11 is a frustoconical hollow inner body 17 arranged, the end of which is smaller Diameter 18 into the discharge opening 13 of the main body 11 flows.
- the end of larger diameter 19 is on the circumference the end face 20 of the main body 11, that of the end face 12 opposite, connected.
- the inner body 17 Larger in the area of the end Diameter 19, the inner body 17 has a radial recess 21 in its wall, which extends over half the circumference of the inner body 17 extends.
- the main body 11 is on his Inner surface with a spiral, protruding rib 22 provided that the toner in the conveying direction 23 on the Recess 21 of the inner body 17 transported out as soon as the cartridge rotates in the direction of arrow 16 about its longitudinal axis.
- the inner surface also with a spiral rib 24 is provided, but in opposite Direction runs like the spiral rib 22, so that with the cartridge 10 rotating in the direction of 16 Toner through the rib 24 to the outlet opening 13 and through this is conveyed out of the cartridge 10.
- spiral ribs 22, 24 ensures that the all of the toner can be transported out of the cartridge 10 and no toner remains in the cartridge 10.
