Definitions

  • the invention relates to a pen tip, in particular a tube pen tip with from behind on the writing tube, the writing tip or the like in its front end.
  • supporting cylinder body push-on writing liquid tank or push-on writing liquid cartridge, which carries a compensation chamber on the outer surface of the front end region, which ends in a connecting bore extending through the wall of the writing liquid tank or the writing liquid cartridge and is covered by a sleeve part between the and the Cylinder body the front end of the compensation chamber is connected to the ambient air.
  • the sleeve part is formed in one piece with the cylinder body, so that an annular space open to the rear is provided between the sleeve part and the cylinder body and openings are provided in the connection area between these two components.
  • a ink tank or ink cartridge is inserted into the annulus, which carries a spiral-shaped ink compensation chamber on the outer surface of the front end area, the front end of which, via the openings between the sleeve part and the cylinder body, with the ambient air, and the rear end of which via the connection hole with the room is connected adjacent to the drop weight body held in the cylinder body.
  • This compensation chamber is covered by the sleeve part.
  • the outer wall of the cylinder body has a relatively short axial length, so that it ends far in front of the connecting bore and this is not covered by the wall of the cylinder body. Rather, the connecting bore is in direct connection with the ink that comes from the tank or from the cartridge into the cylinder body and the writing tube.
  • the ink compensation chamber can be cleaned very easily because it is located on the ink tank to be removed for refilling, so that only the ink tank needs to be completely cleaned before refilling, in order to make the ink compensation chamber that is often filled with dried ink functional again close.
  • the soiled ink compensation chamber is automatically replaced by a clean ink compensation chamber when a new ink cartridge is inserted.
  • this known tube recorder there is a relatively large pressure difference between the front end of the writing tube and the connecting bore, since these two are at a relatively large distance from one another, that is to say there is a relatively large ink column with corresponding static pressure between them.
  • this 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 directly from the annular space between the ink tank or ink cartridge and drop weight body through the connecting hole in the event of overpressure. Therefore, there is also the danger that when attempting 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 pen tip of the type mentioned at the outset is designed in such a way that an inner compensation chamber is provided on the inner surface of the front end region of the write liquid tank or the write liquid cartridge, the rear end of which is connected to the connecting bore such that the entire inner compensation chamber and the Connection bore are covered by the outer surface of the cylinder body and that a transverse bore connected to the inner bore is provided in the front end region of the cylinder body, which is connected to the front end of the inner compensation chamber.
  • the compensation chamber is only partially filled in normal operation, that is to say there is generally only writing fluid in the inner compensation chamber, there is also no danger of writing fluid being thrown out of the compensation chamber to the front when the pen tip is shaken.
  • an external thread for screw engagement with an internal thread provided in the rear end region of the sleeve part can be present on the writing liquid tank or the writing liquid cartridge of the inventive pen tip, so that the sleeve part, and if this is made in one piece with the cylinder body is, the cylinder body can be firmly and captively connected to the writing fluid tank or the writing fluid cartridge.
  • a radially outwardly directed annular shoulder can be provided behind the outer compensation chamber or behind the external thread, against which the rear end of the sleeve part rests, thereby ensuring a defined position of the writing liquid tank or cartridge relative to the sleeve part.
  • sawtooth-shaped projections can be provided on the rear end surface of the sleeve part in its axial direction, the longer tooth surfaces of which opposite to the screwing-on direction of the sleeve part rise, and on the writing fluid tank or the writing fluid cartridge, behind the ring shoulder there may be an external thread having the same direction as the external thread in front of the ring shoulder for fastening 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 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 bears with its front edge against an annular shoulder 18 of the cylinder body 1.
  • this ink tank 11 there is 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 essentially sealing engagement with the inner surface of the ink tank 11.
  • a helical ink compensation chamber 12 From the connecting bore 13 extends in the outer surface of the ink tanks 11 a helical ink compensation chamber 12 to the front, and behind this outer ink compensation chamber 12 an external thread 16 is provided, which ends at a radially outwardly directed annular shoulder 15.
  • a sleeve part 9 is screwed onto the thread 16 from the front, which covers the compensation chamber 12 and has openings 10 at the front end between itself and the cylinder body 11 forms that connect the front end of the ink balancing chamber 12 with the ambient air. Otherwise, the front, radially inwardly drawn edge of the sleeve part 9 holds the cylinder body 11 by abutment against the annular shoulder 18 of the cylinder body in the ink tank 11. 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 forwards by unscrewing the thread 16, and the ink tank 11 can then be pulled backwards from the cylinder body 1.
  • the ink tank exposed in this way can be cleaned and refilled, and during cleaning the compensation chambers 12 and 14 and the connecting bore 13 can also be cleaned without requiring special cleaning of the cylinder body 1 or the sleeve part 9.
  • 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.
  • a correspondingly designed ink cartridge can of course also be used, i.e. an ink container, which was filled by the manufacturer and closed on both sides, but whose front closure lies behind the connecting bore 13 and is broken through by plugging onto the cylinder body 1 from its rear end or from the drop weight safety device 5.
  • sawtooth-shaped projections 20 are formed in the rear end face of the sleeve part 9, which protrude with their tooth faces 21, 22 from the end face, as can be seen in particular in FIG. 3.
  • the longer tooth surface 21 rises in the opposite direction of the thread of the fastening thread 16 for the sleeve part 9, i.e. in the case of a conventional right-hand thread, the rise, viewed from the front end of the sleeve part 9, takes place in a counterclockwise direction.
  • a cover cap can be applied to the sleeve part 9.
  • an external thread not specified, is present on the sleeve part.
