The writing implement 10 has a holder housing 12. When the man of the pen is full, which is open at both ends and an ink tube is inserted into the holder housing 12, Forms container 14, in which an insert 16 is arranged, the rear end 30 of the pen 26 is pressed net is. The insert 16 is made of a material in the front of the ink container 14 to for which can store a large amount of ink, with a good transfer of the ink from the insert 16 for example made of felt. Take care of the pen 26 as shown in FIG. The writing instrument F i g. 3, the insert 16 has an essentially ready-to-write condition, and the air ducts take care of it circular cross-section.

24 serves. This nib holder 24 carries the cross section and has a centrally arranged

actual pen 26. The pen 26 is a star of rays 60 that extends through its entire length

mounted so that its rear end 30 extends into the inlet 25 the pen and the ink flow through

position 16 protrudes, while the nib 38 enables the pen due to capillary action,

protrudes beyond the nib holder 24. As a result, the writing tip 38 is substantially conical

In this arrangement, the ink flows through capillary formed, the apex angle of this cone

The nib holder 24 has a substantially the same number of absorption channels 64 is formed in the borrowed frustoconical front part 50 and in the rear end 30 of the pen, essentially cylindrical rear part 52, these channels 62, 64 have a relatively smaller diameter than the largest diameter 40 small cross section £>. It has been found that, so that a best possible ink flow through the transition point between the rear part 52 and the stylus through the clear width D of the cadres front portion 50, a shoulder is formed on the frusto-conical front portion 50 to achieve 54th The nibs in the order of 0.127 to 0.064 mm nib holder 24 has a central bore 55 must be.

The length L of two mutually narrowing slots 56 that form axial air channels, the opposite legs of the pen should be connected to the interior of the holder housing, however, in the order of 0.51 to 0.76 mm. The slots 56 extend into a portion of the frusto-conical front post to be smaller than the outside diameter of the writing front.

Claims (1)

1 2 window star-shaped capillary channels that cover the patent claim: entire length of the pen to the front end of the writing tip and up to its outer A writing instrument with an elongated holder surface is sufficient. By opening the door while writing, with an ink container in this area, the sticks can attach themselves to their homes, With an insert in the ink tank and the contact surfaces move slightly against each other with one in one end of the holder housing and even lift off from each other .; Changed in the process hold elongated rod-shaped plastic - the cross-section of the writing pen between the rods, its interior on its entire running capillary channels, and that on the writing length The line that is created to convey the ink from the insert surface is of different widths, the ink container to its outside of the shark. With a soft and / or resilient pen housing located cone-shaped. underlay and / or with only slight pressure Capillary channels are penetrated by the writing tip, which is exerted by the writer gene is characterized in that the rods are at least over part of their the slit-shaped capillary channels (62) do not lift sufficiently from one another in the transverse length, so that cut, to a ray star (60) with the writing paste not even and sufficient are connected to each other. penetrates to the front end of the writing tip and therefore no or at least no uniform ger line emerges. On the other hand, it can 20 Writing utensils tend to blob on a hard writing surface and high pressure, as the sticks The invention relates to a writing instrument with a surface then too far apart (Austrian Holder housing, with an ink container (see patent specification 202 897). In this housing, with an insert in the ink, based on this prior art, is the container and with one in one end of the Halterge- 25 invention the underlying technical problem, a to create the elongated, stick-shaped artificial writing instrument held in the house, which is suitable for a practically non-material writing pen, its interior has an even ink length over its entire limited period of time to promote the ink from the insert of the flow and provides an even stroke. To the The invention provides an ink container for its outside of the holder- solution of this object housing located, conical design 30 writing implement of the type mentioned above, Writing tip is crisscrossed by capillary channels. that the slit-shaped capillary channels in the transverse A writing instrument of this type is known, when seen in section to form a star of rays with one another to which the pen is connected to a pen filled with fine fibers. Is hollow cylinder. Between the fibers there remain between This design of the writing instrument according to the free spaces that form the capillary channels. This invention has the advantage that the ink or Capillary channels are extremely fine, so that they write paste a uniform passage across due to the small amount of waste carried along by the ink. The cross section of the slit-shaped impurities can add. Since the fibers do not reach the capillary channels, on the one hand it is sufficiently small run completely parallel to each other and also kinks to promote the ink by capillary action, and have, on the other hand, an irregular transverse 40 is also large enough to allow the ink sectional shape of the capillary channels. Furthermore, there is a steady flow and no impurities the well-known pen cannot be ruled out that there are places where they are unhindered protrude at the free end of the pen and close one or more capillary channels, fine fibers over time, especially zen. The slit-shaped capillary channels and when writing with greater pressure, to a certain extent they complement each other to form a star of rays be squeezed wide. With this known offer a uniform passage cross-section, Writing implement is therefore a uniform and not a constant flow of ink constant ink flow as well as an even and even line thickness guaranteed.
