Definitions

  • the invention relates to a writing tip with a ball for liquid ink, with a tube of small diameter, in which an indentation serving for the ball system is provided, an ink conductor essentially filling the interior of the tube being provided in the tube.
  • the invention further relates to a method for producing such a writing tip.
  • European patent application 0066541 (application number 82810220.1.) Describes a method for producing a ballpoint pen tip fed with liquid ink, in which the starting material is a tube with an inner diameter of 1 mm. This tube is subjected to various deformation stages in order to produce the writing tip and to receive the ball, the inner diameter of the tube in the area of the tip in particular being reduced in several stages. The free end of the tube is ela deformed 'so that the ball can be pushed in from the front and the tip resiliently surrounds the ball. An ink conductor extends inside the front portion of the writing tip and is axially spaced from the ball.
  • the object on which the invention is based is therefore to specify a method for producing a writing tip for liquid ink of the type outlined at the beginning and to propose a writing tip which is safe and effective in operation without having to use technically complex means.
  • the writing tip according to the invention is characterized in that the tube, with the exception of the circumferential, cylindrical cut-out indentation, has the same diameter throughout and in the front area of the tube in the inner wall of which parallel and spaced-apart ink channels are provided, which are so long, that they partially surround the ink conductor, and wherein the ball is held between the circumferential indentation forming a ball bearing surface and an inwardly curved edge at the free end of the tube.
  • the main advantage of the proposal according to the invention is that a thin-walled tube can be used with a diameter which corresponds essentially to the ball diameter, in particular by the Formation of the axially extending ink channels, which partially overlap the ink guide located further back in the tube, a very good ink contact between the ink guide and ball is guaranteed, so that lines of uniform line width can be generated with such a writing instrument.
  • the writing tip according to the invention is simple to manufacture and thus inexpensive.
  • the scream is used to manufacture pointed a thin-walled tube 5 with an inner diameter of about 0.51 mm.
  • circumferentially spaced, axially extending grooves or channels 3 are formed in the inner wall of the tube 5, which are produced in particular so that the tube 5 is fixed and centered in a collet, afterwards with a stamp in the form of a profile needle with sharp edges, these channels are granted.
  • the material cleared from the channels 3 is pressed away with a further punch and at the same time the inner circumference of the tube 5 is deburred in the area of these channels 3.
  • An outer cone 7 is provided in the front area of the free end of the tube.
  • a circumferential, annular indentation 9 is rolled in with the aid of a tool 10.
  • a ball support 6 is created by this continuous indentation.
  • the channels 3 follow the indentation of the inner wall of the tube.
