Definitions

  • the invention relates to a writing liquid tank or a writing liquid cartridge to be plugged onto the rear end of the cylindrical body of a writing tip, a writing tip or the like carrying a writing tip, in particular a tubular writing tip, which carries a compensation chamber on the outer surface of its front end region which can be covered by the inner surface of a sleeve part of the pen tip and which is connected in the rear region to a connecting bore extending through the wall.
  • the tank or the cartridge can be inserted into an annular space which is open to the rear between the cylinder body and is formed integrally with this sleeve part, which has openings in the connection area between the sleeve part and the cylinder body.
  • the helical ink compensation chamber is covered by the inner surface of the sleeve part, and its front end is connected to the ambient air via the openings.
  • the rear end of the ink compensation chamber communicates via the connecting bore with the space adjacent to the drop weight body held in the cylinder body.
  • the ink compensation chamber does not achieve optimal pressure compensation.
  • the compensation chamber is relatively short and thus only has a relatively small volume for receiving ink, the ink entering the compensation chamber through the connecting hole in the event of overpressure directly from the annular space between the ink tank or ink cartridge and drop weight body. Therefore, there is also the danger that when trying to make the writing instrument capable of writing by spinning movements, ink will be thrown out of the openings between the sleeve part and the cylinder body at the front.
  • a writing fluid tank or a writing fluid cartridge of the type mentioned at the outset is designed according to the invention in such a way that the inner end of the connecting bore is provided with one on the inner surface of the front end region.
  • inner compensation chamber is connected, which can be connected to a transverse bore provided in the front part of the cylinder body and extending into the inner bore of the cylinder body.
  • a compensation chamber both on the inner surface and on the outer surface of the front end region, and these compensation chambers are connected to one another via the connecting bore, while the writing liquid enters the inner compensation chamber at its front end .
  • Such a tank or such a cartridge is intended to be plugged onto the cylinder body of a pen tip, in the receiving part of which a transverse bore is provided in the front part for the tank or the cartridge, while the area behind the transverse bore is dimensioned in such a way that that it covers the entire inner compensation chamber of the attached tank or cartridge.
  • the writing liquid tank according to the invention or the writing liquid cartridge according to the invention is thus connected to such a new writing tip, there is on the one hand a small distance between the front end of the writing tip and the entry area of the writing liquid into the compensation chamber, i.e. a small pressure difference, and on the other hand a relatively long, i.e. large volume Compensation chamber, because the writing fluid can flow backwards in the inner compensation chamber, then through the connecting hole and then from the connecting hole in the outer compensation chamber to the front.
  • the compensation chamber is only partially filled during normal operation, that is to say there is generally only writing fluid in the inner compensation chamber, there is also no risk of writing fluid being thrown out of the compensation chamber when the pen tip is shaken.
  • the compensation chamber located on the surface preferably has an external thread for screw engagement with the rear end region of the sleeve part of the pen tip, so that the sleeve part, and if this is formed in one piece with the cylinder body, the cylinder body is also firmly and captively connected to the writing liquid tank or the writing liquid cartridge can.
  • a simple attachment of the holder shaft for the writing tip can be achieved by providing an external thread behind the ring shoulder onto which the holder shaft can be screwed.
  • a writing liquid tank according to the invention is shown partly as a view, partly in section, which is attached to a tube pen tip and connected to a holder shaft.
  • the tube pen tip shown contains a cylinder body 1, in the front end of which the tube 4 is held by means of a metal holder 3 embedded in the cylinder body 1.
  • a drop weight body 2 in the inner bore of the tubular cylinder body 1 there is a drop weight body 2, in the front end of which the cleaning wire is fastened in a manner not shown, which extends into the writing tube 4 and can be moved back and forth with the drop weight body 2 in the axial direction.
  • a falling weight safety device 5 having a central opening is inserted.
  • a transverse bore 7 which connects the outer cylinder surface of the cylinder body 1 with its inner bore.
  • a ink tank 11 is attached to the cylinder body 1 from the rear and rests with its front edge on an annular shoulder 18 of the cylinder body 1.
  • a helical compensation chamber 14 in the inner surface, the front end of which is connected to the transverse bore 7, while its rear end is connected to a connecting bore 13 extending through the wall of the ink tank 11.
  • This inner ink compensation chamber is covered by the outer cylindrical surface of the cylinder body 1, which is in sealing engagement with the inner surface of the ink tank 11.
  • a helical ink compensation chamber 12 extends forward from the connecting bore 13 in the outer surface of the ink tank 11, and an external thread 16 is provided behind this outer ink compensation chamber 12 and ends at a radially outwardly directed annular shoulder 15.
  • the rear end of the sleeve part 9 touches the annular shoulder 15 of the ink tank 11.
  • the sleeve part 9 can be removed by unscrewing the thread 16 to the front, and the ink tank 11 can then be pulled off the cylinder body 1 to the rear.
  • the ink tank exposed in this way can be cleaned and refilled, and the cleaning chambers 12 and 14 and the connecting bore 13 can also be cleaned with the cleaning without any special cleaning of the cylinder body 1 or of the casing element 9 being necessary.
  • the newly filled ink tank 11 is then put back on the cylinder body 1, and the two elements are connected to one another by screwing on the sleeve part 9.
  • the ink tank 11 can also be replaced by an ink cartridge, which has been filled by the manufacturer and sealed on both sides, the front closure of which, however, lies behind the connecting bore 13 and by being plugged onto the cylinder body 1 is broken through by its rear end or by the drop weight safety device 5.
