Exemplary embodiments are described in greater detail below explained.

The Sehreibgerät invention, as Unterechriftaieder ,, 1, registered under dan Kamen "Pentel '· al" Varenseichen and ^ «on demaalbtn-SrfInder performed consists of a rigid U faaerkarn in the form of a tapered spring au · tinem flexible and hard. material in a form suitable for everyone ", ^soft: 0 terhin there is resinified au" small .angeordneten in the longitudinal direction and a unit-forming fibers, under Verwen- \ dung of a thermosetting or heat-reversible resin..

With reference to what has been said about the core of the writing instrument,, BATH ORIGINAL

it is possible to show the tiles if the writing instrument is water-resistant or non-discolouring Ink, which consists of dye and ink and contains little activating agent • is used, with the liquid ink in the Core does not flow, and since there is no ink leakage, it is impossible free to write. On the other hand, water-soluble ink, which contains a lot of activating agent, flows in a relatively shortened core. ■ honestly well and without loss.

Accordingly, the invention also relates to a pen with hard fiber core without loss of liquid ink, and in particular to that Hard fiber pen so that it is possible to write a letter with liquid Writing ink BU, this continued duroh without loss the inside of the core flows, the ink is water-resistant or not discolored and made of some dyes is made and the ink contains little activating agent, the editing is easy and the usual pens with hard fiber core.

Exemplary embodiments of the invention are set forth below is described with reference to the drawings, in which the same reference symbols denote the same or equivalent parts.

FIG. 1 is the eleventh embodiment of a writing instrument according to FIG der Inventionι 2 is an inner part of said writing implement, and ink picked up by the core 3 flows well through the divided shells 7 into the end portion of the core 3 in the shown figure

Fig. 2 is an ink absorbing body with felt inserted in an inner part, Fig. 3 shows one solidified by rolling Hard fiber core, so that the selected fiber has strong and elastic properties, by using a thermosetting or thermoplastic resin, after which the fibers are arranged in the longitudinal direction to be in the form of a small unit to be connected. Entapreohehd dam preceding a hard fiber core is obtained, its surface is covered by a thick resin film, as this hard fiber core is produced by continuous drawing is formed by the required narrow opening. Farther 4 is a ring attached to the end piece of the core. In Figures 2-5, the core 3 is cut open and forms a divided groove 6, two or four grooves may be formed, extending from the end 5 of the body in the longitudinal direction run up to the mentioned Hing 4.

Accordingly, whether the particles are water-insoluble or not discolouring ink have little activation agent, even if the not completely liquid ink is used, it can flow from the surface of the divided groove 6 into the inner part of the core without loss. Because of this, it is an even Writing possible.

As shown in Figures 6 and 7, is expedient a plurality of grooves 7 on the outer surface of the end piece

of the cores 3 in the longitudinal direction on the side of the ring 4 and running to the tip, arranged. As shown in FIGS. 8 and 9, Ea is also possible instead of the grooves 7 to provide a plurality of depressions 8 in the surface of the end piece of the core 3.

The mentioned depressions 8 can with a drill in one A diameter of about 0.5 to 0.8 ma can be drilled into the core 3. Furthermore, ββ is expedient, the grooves 7 and the depressions also to be provided in the upper part of the fixed hanging 4 *

Duroh the writing instrument according to the invention it is possible what also always for a water resistant or yourself Non-discoloring ink with larger coarse grains is used so that this ink penetrates evenly into the end piece of the core flows, whereby the machining is easy and the usual hard fiber cores are surpassed with which it is because of the not flowing ink was not able to write evenly.
