Definitions

  • the invention relates to an ink pen with a writing tip, with a tank for the liquid ink and with means for guiding the ink from the tank to the writing tip.
  • Such ink pens are known in particular as fountain pens, but also as so-called roller balls or fiber pens.
  • the ink is transported from the tank to the nib by capillary action according to one of two principles. If the tank gradually empties in this way, a negative pressure gradually develops in the tank, which would prevent further ink from reaching the writing tip. In order to avoid this, the negative pressure must be eliminated by supplying air from the outside.
  • tampon memory that is to say a porous material, for example containing fibers, which is impregnated with the ink.
  • the disadvantage of these tampon stores is that they cannot be completely emptied. Increases after some namely the letter T intenmenge and thus the extent to which the porous pad memory is moistened, ab, so the ink flow diminishes, that is, the print quality decreases. With the same volume, the tampon storage has the disadvantage over the conventional tank that it has to be refilled or replaced more frequently.
  • a higher write speed can be with a T intenschreiber with tank achieve because there is the tampon Schreiber difficulties of ink flow at high write speeds, since the ink from the more humid regions of the tampon memory passes slowly to the regions by the rapid writing partially dried are. and with increasing emptying of the tampon, the counteracting the ink flow
  • the tank has many advantages, it has the disadvantages mentioned above.
  • Such is an ink very sensitive to temperature, and space must be provided for compensation rooms and the like, for example in the form of capillary stores.
  • the internal pressure in the tank will depend on the fill level, since with different fill levels, different hydrostatic pressures at the opening at which the air is to enter modifies the entry of air bubbles.
  • the object of the invention is to provide an ink recorder of the type mentioned, which has the advantages of the tank memory, but it has a temperature variations and pressure variations and the F üll- was independent ink.
  • the solution according to the invention is that the tank is closed off by an open-pored porous wall at least on the side facing away from the writing tip.
  • the porous wall is as follows.
  • the wall is soaked in ink.
  • the porous wall is expediently connected to the lower region of the tank (in the writing position) via appropriate capillary lines, for example also a porous wall, in which ink is normally always present located.
  • the side walls also consist of open-pored, porous wall material, so that the upper part is always kept moistened via these side walls.
  • the tank according to the invention with an open-pore porous wall can be used with all ink writing devices, both with roller balls, fiber pens and fountain pens.
  • the tank is advantageously delimited on all sides by open-pore porous wall material, since in this way the upper part in the writing position always remains well wetted with ink.
  • the tank is expediently surrounded in the lower region and on the side walls with an impermeable material.
  • the impermeable material of the side walls and - apart from the means for directing the ink to the writing tip - the part facing the writing tip are expediently surrounded by an impermeable material.
  • This impermeable material can be shrunk plastic, for example.
  • the porous wall material can also consist of plastic. Conveniently, however, it can also consist of glass, or of sintered metals or other materials.
  • the porous wall material advantageously has an average pore diameter of 10 to 100 ⁇ m, preferably approximately 10 to 50 ⁇ m. It is very particularly advantageous if the porous wall material has an average pore diameter of approximately 25 ⁇ m.
  • the porous wall is soaked with ink.
  • the porous wall material has been hydrophilized, that is to say has been subjected to such an additional treatment that the wall material is particularly hydrophilic, that is to say it attracts water and soaks up particularly well with water or ink.
  • the material is treated in such a way that the porous wall material is rendered hydrophobic, that is to say water or ink repels.
  • the porous wall material repels the ink liquid, which can no longer penetrate the wall material.
  • an ink film forms on the inside of the hydrophobic wall, which seals off the air space inside the tank against the outside air.
  • the wall material is selected so that it completely repels the ink, so that here no ink film wets the hydrophobized wall on the inside of the tank. In such cases, ink would leak out of a normal fountain pen.
  • this additional cover can in turn be formed by a porous wall if it is provided that at least some of the walls of the tank are formed by a hydrophilized porous wall material which is covered on the outside by a hydrophobic porous wall.
  • FIG. 1 shows a conventional ink pen, for example a fountain pen, with a tank 1 which is filled with ink 2. There is an air bubble 3 above the ink 2. If ink 2 is now removed by capillary lines 5 when writing in the direction of the arrow 4, a negative pressure gradually forms in the tank. To equalize the pressure, a small opening 6 is provided in the lower end face of the tank in the writing position, through which small air bubbles 7 rise in the ink 2 with a correspondingly large negative pressure and thus reduce the negative pressure of the air volume 3. When the temperature rises or the outside pressure drops, the air in space 3 expands, so that ink is pressed downwards or outwards through the capillary tube 5 and possibly also the opening 6. So that the ink flowing through the capillary tube 5 does not drip out, a relatively complex capillary memory 8 must therefore be provided, for example, in the spring of a fountain pen.
  • a relatively complex capillary memory 8 must therefore be provided, for example, in the spring of a fountain pen.
  • Fig. 2 shows a first embodiment of the ink pen according to the invention.
  • the upper end wall 9 (in the writing position) of the tank 1 consists of an open-pored porous material.
  • the side walls 10 also consist of such open-pored porous wall material.
  • the lower end face consists of an impermeable wall material, although it could also consist of open-pore wall material.
  • Lower end face 11 and side walls 10 are from a jacket 12 surrounding impermeable material so that no ink can evaporate here.
  • the ink is taken down when writing in the direction of arrow 4. It is conducted from the tank to the outside through appropriate capillary conductors, for example through a writing wick 13 made of porous material similar to that of the wall material.
  • FIG. 4 shows a further embodiment which has a writing tip with a ball 15 and a writing wick 13.
  • the micropores are only indicated in part of the walls 9, 10 and 11 of the tank, although these micropores can of course be present anywhere.
  • the cross-section of the wick is dimensioned so that the flow resistance is small enough to be sufficient even for broad nibs or broad pen tips
