Definitions

  • the invention relates to an ink writing device according to Preamble of claim 1.
  • Such ink pens are well known (e.g. DE-A-1 461 628, DD-A-0 151 561).
  • the annular pressure equalization chambers Shaped bodies having capillary dimensions of such Ink pens are injection molded in a jaw mold made which has two mold halves, each in Half of the form of sheet metal packages held from thin-walled sheet metal lamellae are, for example, have a thickness of 0.10 mm to 1.0 mm can.
  • the laminated core is one of the mold halves an axially extending longitudinal plate provided in the peripheral region provided by the axially in the molded body to be produced running, capillary ink guide channel, approximately in the form of a Flattening (DE-A-3 429 031) is formed from which in operation Ink enters the annular pressure equalization chamber when Overpressure occurs inside the ink pen.
  • the object of the invention is a writing instrument according to the preamble of claim 1 to improve in that without significant Manufacturing effort is achieved that the annular pressure compensation chambers of the molded body over practically their entire Circumference have a constant width.
  • a writing instrument designed according to the invention such that the Shaped body to form the ink guide channel an axially extending Has flattening and that the mold parting plane extends through this flattening.
  • the mold parting plane lies in the writing instrument according to the invention not offset by 90 ° to the radii through the center of the Ink guide channel, but in the plane of such radii, the Ink guide channel formed by flattening the molded body becomes.
  • the formation of the ink guide channel by flattening makes it possible in the mold halves to match the jaw shape radially inwardly projecting areas to be formed in the Close the jaw shape together and open the Cheek mold after performing the injection molding process and Do not hinder ejection of the molded article produced.
  • the annular pressure equalization chambers are covered by sheets of Sheet packets formed in the mold halves, each of which one side of the flat to diametrically flat extend opposite side of the molded body, so that the Sheets of the two mold halves on this opposite side collide. If there is a certain axial offset of the Sheet metal results, so this does not reduce the volume of the annular pressure equalization chambers, even if this on the Flattening opposite side not at all with each other stay in contact.
  • each mold half is a half forms such a pressure compensation chamber and each of these halves in connection with the flattening forming the ink guide channel stands, there is a connection of the entire pressure compensation chamber with the ink guide channel, without a possible Interruption in the course of the pressure compensation chamber at the Ink guide channel opposite side to a volume reduction would lead.
  • the flattening can be in the area of a formed in the molded body Partition wall that interrupts the annular spaces in the circumferential direction, the flattening being a width at least equal to that Thickness of the partition in its radially outer area has a sufficient connection between the ink guide and the to obtain annular pressure compensation chambers.
  • the mold parting line runs through the middle of the partition and the middle of the flattening.
  • the areas of the disc-shaped areas opposite the flattening Walls of the molded body can form the air duct be flattened.
  • the front end of the air duct can on one in connection with the ambient air standing annulus end.
  • the Writing tip through an in an axial through hole of the Shaped body used wick or liquid guide educated.
  • the writing instrument shown has a protruding writing tip 1, the front end of a wick or liquid guide 2 is formed, which is in an axial through hole 4 of a molded body 3 to be described and protrudes at the rear end. At the front end is the wick or liquid guide 2 is jammed in the front Section 5 of the molded body 3 held.
  • the molded body 3 is seated in a holder shaft 20, the rear closed end, in the protruding end of the wick or liquid body 2 protrudes with free writing fluid, preferably ink, which may also contain micro-color particles.
  • This writing fluid is used in the usual way a wick body 2 through its capillary structures formed in the body from the rear end to the writing tip 1 and is at Use of a non-porous liquid guide body 2 in the surface of which has capillary channels to the writing tip 1 guided.
  • the molded body 3 has in the usual manner in the circumferential direction running circular pressure equalization chambers 13 capillary Dimension limited by lateral disk-shaped walls 12 are and their chamber width, as is also known, from behind increases forward.
  • the flat 10 forms together with the enveloping Holder shaft 20 has a capillary ink guide channel 11 (FIG 1), the axially from the rear flange 8 of the molded body to a lying in front of the annular pressure equalization chambers 13 disc-shaped wall 14, which may be the front Boundary wall of the front pressure compensation chamber can be.
  • an air duct 16 is formed, which one formed between disc-shaped walls 14 and 18 Annulus 17 and another, through a disc-shaped Partition 19 interrupted annular space and an axial groove 7 in the effecting front clamping of the molded body 3 in the holder shaft 20 Section 6 of the molded body 3 in connection with the ambient air stands.
  • the molded body 3 has one Formation of the ink guide channel 11 serving flat 10, the on both sides of the partition 9 with the annular pressure compensation chambers 13 communicates.
  • a jaw mold made of two mold halves is used, those in the closed state with their parting level in level 25 lies.
  • Each of the mold halves thus contains laminated cores for formation of the annular pressure compensation chambers 13, which are in the parting plane 25 and on the partition 9 diametrically opposite Side collide.
