Definitions
- the invention relates to a writing liquid tank or a writing liquid cartridge for plugging onto the rear end of a writing tube, a writing tip or the like in the front end.
- supporting cylinder body of a pen tip in particular a tube pen tip, which, or 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.
- a known writing fluid tank or a known writing fluid cartridge of this type (DE-A-1967021) is on the outer surface of the front end region.
- an ink compensation chamber provided .
- 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 provide an optimal pressure compensation.
- the compensation chamber is relatively short and therefore only has a relatively small volume for receiving ink, the ink in the event of overpressure directly from the annulus between the ink tank or ink cartridge and drop weight body enters the compensating chamber through the connecting bore.
- a writing fluid tank or a writing fluid cartridge of the type mentioned at the outset is designed in such a way that the inner end of the connecting bore is connected to an inner compensation chamber provided on the inner surface of the front end region, which is provided with an expansion chamber provided in the front part of the cylinder body. transverse bore extending into the inner bore of the cylinder body is connectable.
- inventive recording liquid tank or in the inventive ink cartridge is thus located both on the inner surface as well as on the outer surface of the front end region an equalizing chamber, and that compensation chambers are connected via the connecting hole with each other, while the writing fluid inlet in. Said inner balance chamber at its front End done.
- Such a tank or such a cartridge is intended to be plugged onto the cylinder body of a pen tip, in the front part of which a transverse bore is provided in the receiving surface for the tank or the cartridge, while the area behind the transverse bore is dimensioned such that he 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 area of the writing liquid tank according to the invention or the writing liquid cartridge according to the invention behind the compensation chamber located on the outer 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 it is formed integrally with the cylinder body, also the cylinder body. can be firmly and captively connected to the writing fluid tank or the writing fluid cartridge.
- 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 falling weight body 2 In the inner bore of the tubular cylinder body 1 there is a falling 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 is moved back and forth with the falling weight body 2 in the axial direction can.
- a falling weight safety device 5 having a central opening is inserted.
- transverse bore 7 which connects the outer cylinder surface of the cylinder body 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.
- 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 one through the Wall of the ink tank 11 extending connection bore 13 is connected.
- 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.
- From the connecting bore 13 extends in the outer surface of the ink tank 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 on 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 back from the cylinder body 1.
- the ink tank exposed in this way can be cleaned and refilled, and during cleaning the equalizing chambers 12 and 14 and the connecting bore 13 can also be cleaned without special cleaning of the cylinder body 1 or Sleeve part 9 would be required.
- 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.
