Definitions

  • the present invention relates to a refill device for fine-grained or powdery goods, in particular toners for toner cartridges of laser printers, photocopiers and the like. the like
  • Either disposable toner modules, which are replaced after toner consumption, or refillable toner cartridges are common for the after-supply.
  • a refill device for fine-grained or powdery goods in particular toner for toner cartridges of laser printers, photocopiers and the like.
  • a container which holds refillable material and which on the outlet side merges via a funnel-shaped wall part into an inlet connector which is intended for insertion into a filling opening of a toner cartridge and comprises a closure pin or closure cone which can be displaced relative to the container against the action of a closing spring.
  • each toner cartridge with a corresponding filling opening in a form-fitting manner to the inlet nozzle on the refill device is provided, quickly and absolutely clean and to be refilled several times with toner, whereby the pressure exerted to move the sealing cone against the action of the closing spring ensures an effective seal between the inlet nozzle and the cartridge to be filled, thus preventing the toner from being dusted into the environment.
  • a further refinement of the subject matter of the invention can then preferably consist of the closure cone being displaceable out of the inlet connection via an actuating rod which penetrates the container and can be pressed down against the spring, or that the closure cone on the inside of a cylindrical outlet part forming the inlet connection Container surrounding, arranged against the action of the spring sleeve
  • the container is closed on the top side by a cover part which has a vent hole which is closed by a tear-off and guarantee film.
  • the present invention further relates to a use the refill device according to the invention for refilling toner in a toner cartridge of a laser printer, photocopier or the like.
  • the refill device according to FIG. 1 comprises a container 1 which holds the toner and, on the outlet side, merges via a funnel-shaped wall part 2 into an inlet connection 3 intended for insertion into a filling opening of a toner cartridge (not shown).
  • a closure cone 5 cooperates with the inlet nozzle 3, which can be pressed out of the inlet nozzle 3 against the action of a spring 4 in order to allow the toner to flow out.
  • the wear cone 5 is fastened to an actuating rod 6, which penetrates the container 1 upwards and can be pressed down against the spring 4 and which carries an actuating flange 7 at the free end, which forms a counter shoulder for the spring 4, which is supported on the other hand on the cover part 8.
  • a securing sleeve (not shown in detail) can be placed on the free end of the actuating rod in order to prevent the locking cone from being pressed down undesirably.
  • An essentially axial bore 9 in the actuating rod 6 serves to vent the module to be filled (not shown).
  • a bore 13 in the cover part 8 serves for pressure equalization in the emptying container 1, which is expediently closed by a tear-off and guarantee film 12.
  • the sealing cone 5 ' is alternatively arranged on the inside of a sleeve which is open on the bottom and forms a inlet part 3' and surrounds a cylindrical outlet part 10 on the container 1 and can be pressed in against the action of the spring 4 between it.
  • a jacket bore 14 serves to vent the module to be filled (not shown).
  • the container of the refill device can be made of any material, but preferably crystal-clear plastic, the latter allowing the toner color to be recognized without further markings.
  • the container can have any geometric cross-section, but can preferably be cylindrical.
