Definitions

  • the invention relates to a writing instrument with a writing fluid reservoir in the form of a fiber body, which has capillary channels in the direction of the longitudinal fiber extensions, and with a housing accommodating the writing fluid reservoir, in the front end of which a writing tip is held, a writing fluid conductor extending coaxially in the writing fluid reservoir , which is in liquid-conducting connection with the writing tip.
  • the writing fluid store consists of an essentially cylindrical fiber body, in which the fibers extend in the direction of the longitudinal axis of the cylinder and thus parallel to the writing fluid conductor arranged coaxially in the fiber body.
  • the fibers transport the writing liquid received by the writing liquid storage when consumed as a result of writing or drawing on the one hand in the direction of the axially extending capillary channels and on the other hand in the radial direction to the writing liquid conductor.
  • a writing instrument of the type mentioned at the outset is designed in accordance with the invention in such a way that the writing fluid store consists of fibers which extend perpendicular to and radially with respect to the longitudinal axis of the writing fluid conductor.
  • the fibers of the writing fluid reservoir are arranged in such a way that they extend from the outside inwards in the direction of the coaxially arranged writing fluid conductor and are in fluid-conducting connection therewith, so that the fibers Capillary channels formed run in the radial direction.
  • Writing fluid in operation i.e. if the writing liquid conductor releases writing liquid to the writing tip during writing or drawing, it is transported from the writing liquid store in the direction of the writing liquid conductor.
  • the writing fluid conductor inserted into the writing fluid reservoir is preferably a flank-open, capillary-channel wick which receives writing fluid from the radially inner ends of the fibers of the writing fluid reservoir via its peripheral surface.
  • a particularly simple construction results if the front end of the writing liquid conductor forms the writing tip, since then only one component is required for the writing liquid conductor and writing tip.
  • the writing instrument shown has an essentially cylindrical, elongated housing 1, in the front end of which there is a passage opening into which a support tube 3 is inserted. Furthermore, there is a ventilation hole 2 in the front end face of the housing 1, via which a pressure equalization between the interior of the housing 1 and the surroundings is effected.
  • a cylindrical writing fluid reservoir 4 is inserted into the housing 1 and extends essentially through the entire length of the housing.
  • the writing fluid reservoir is constructed from individual fibers which form capillary channels in the direction of their longitudinal extent, the longitudinal extent of the fibers extending radially. This means that the fibers run radially outwards from a writing liquid conductor 5 inserted coaxially into the writing liquid memory.
  • the fibers are in liquid-conducting connection, usually in direct contact, with the writing liquid conductor 5, and the writing liquid conductor 5 is a flank-open wick known for this purpose, which has capillary channels. It extends forward from the writing fluid reservoir 4 through the passage opening in the housing 1 and the support tube 3, so that its front end forms the writing tip of the writing instrument.
  • the writing liquid conductor 5 is fed from the writing liquid storage 4 soaked with writing liquid, such as ink, via the radially extending capillary channels of the writing liquid storage, which reaches the writing tip 5 to the front and is applied to the writing pad from there.
  • writing liquid such as ink
