No. 2487340). This, which melts at ordinary temperature, is a completely normal pen, or a fine, foam-like elastic which has a claw 14/16 in its writing tip 5 plate or a synthetic resin plate of great porosity that holds the ball 19. The ball then flows or is provided by powder metal. F i g. 9 shows the ink over slot 31/32 too. The nib has an overall device of a ballpoint pen device, that is to say, separate from the penholder, an ink reservoir which is attached to a penholder 6. As in voir on. F i g. 4, 5 and 10, the ballpoint pen is shown, in contrast, the present invention is in the direction of the invention with a fastening that the ink container of the pen device is attached to the pen holder; the shape itself is formed, the ink reservoir inside this fastening piece is held in a circular shape and sits half of the spring. The invention therefore exists and is thus a modification of the invention. As shown in the fact that the pen has a longitudinally in Fig. 6, 7, 8, 11 and 12, the spherical extension of inner surfaces of the pen as 15 writing device of the invention has an ink container wall surfaces surrounded and in the ter 1, the shape of which is conically modified and so-called the ink container one in ballpoint pens per se with a modification of the shape shown first, the sinking surface of the ink M- represents. Low protective layer 4 made of liquid or paste-like form. From the explanations given above, it emerges that the medium does not mix with the ink. In particular, the shape of the ink container and the extension piece 3 in cross-section of the circular ring feeder 1 is conical or pyramidal and has a shape and that the ink container has a conical ball (2) at its front end, which has a fastening or pyramid-like shape. piece 3 at the rear end, through which it is attached to the spring piece 3 at least over part of its length the 25 holder; Furthermore, the protective layer 4 has a cross section of half a circular ring. against leakage of ink at the rear end of the In an exemplary embodiment, the ink container is shown. This allows the ball invention shown in the drawings, spring-free easily to ordinary spring-F i g. 1 shows the longitudinal section of such a ball holder or fountain pen, attached or descriptive device, which according to the present invention is removed, and is just as light as it is produced in the case of fertilization; homely pens. On the other hand, in Ge-F i g. 2 shows a section along the line AA in contrast to ordinary spring holders according to that of FIG. 1 represents; Invention the ink is stored in the ink container, Fig. 3 is the front view of Fig. 1; and therefore offers the user this ball-fig. 4 shows the longitudinal section of another writing device for great convenience,
game of a ballpoint pen device according to the invention is the introduction of a lying invention is; Ballpoint pen, which can easily be attached to the usual F i g. 5 is the top view of FIG. 4; borrowed pen pens or fountain pens attached. Therefore, the present invention is embodied; need the length or diameter of the ballpoint pen fig. FIG. 7 shows the section along the cutting device according to the invention from the line 3 through FIG. 6; speaking dimensions of ordinary penholders F i g. 8 is the front view of FIG. 6; not to be very different.
FIG. 9 shows the side view of the ballpoint pen device according to the invention as shown in FIG. 1, which can be attached to or removed from a conventional pen holder instead of the conventional pen Pen holder is attached; 10 is a side view, as shown in FIG. 4, spring holders. The ball spring of the present invention is shown attached to an ordinary pen holder 5 ° so that the ink is mounted in the ball; pen itself is kept, the ballpoint pen Fig. Fig. 11 shows the side view of the ballpoint pen on top of the conical ink container as shown in Fig. 6 supported on or pyramidal shape to which the ordinary pen holder is attached, the cross section not always being circular; a longitudinal sectional plane of the fastening is indicated by the dashed line 55 of the ball spring at the rear of the; Container attached; a protective layer is also provided.
