The present invention relates to a plastic pen body for writing well like a fountain pen.

In general, the calligraphy is different from the pen writing written by fountain pens, ballpoint pens, pencils, etc., in that the penetrating or penetrating portion of the writing has a sharp part due to the intrusion or protrusion of the brush, or a gradually thinning flow part at the removing part of the brush.

Therefore, the calligraphic writing as described above could not be used as a pen body with the same orientation as a conventional fountain pen.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a plastic pen body designed to be written well, such as a pen, while having a pen-like direction with a fountain pen.

When one embodiment of the present invention is described according to the drawings of FIGS. 1 to 4, the plastic pen pen according to the present invention is a nylon formed with elastic wetting molybdenum, which is integrally molded in the shape of a nib of a fountain pen. The nib 1 has a triangular cross-sectional shape, such as a third, with a sharp back and flattened abdomen, and the tip 2 touches an angle θ of about 45 degrees to 65 degrees to suit the writing angle. At the same time, the ink groove 3 through which the ink flows is cut into the pen tip abdomen so as not to be separated from each other.

In addition, the pen tip 1 is bent like a pen tip to give elasticity so that the tip 2 can be pressed, and the tip 2 reaches an appropriate range ℓ to always maintain the same cross-sectional shape even when the tip 2 is worn. It has the same width and the same cross section (triangle shape).

(4) is a mounting hole perforated at the rear end of the pen body so as to communicate with the ink groove 3, so that the pen body mounting is possible by covering the tip protrusion 5a of the eccentric 5 with the mounting hole. It is.

In FIG. 5, reference numeral 6 denotes a writing instrument body 7 having a pen nib 5 embedded therein, and a tightening screw for pushing the nib 5 together with the packing 8, and 9 a piercing tube to tear the sealing film of the ink bottle. Numerals 10 and 10 are ink grooves provided in the pen core 5 to communicate with the ink grooves 3 of the pen body abbreviation as shown in the drawing.

Reference numeral 11 denotes an air introduction hole.

Next, a pen body of the second embodiment of the present invention shown in FIGS. 6 and 7 will be described. The ink groove 3 of the pen body of the first embodiment shown in FIGS. The pen tip part 1 is cut off so that the pen tip 1 does not fall, so that a part of the opening 3a is formed on the back side.

In addition, the pen body of the third embodiment shown in FIG. 8 is attached with a pen core plain thread 5a (蛇 服 部) as shown in FIG. 5, which integrally constitutes the eccentric 5, and also shown in FIG. The pen body of the fourth embodiment is integrally provided with the protruding insert portion 12 which is to be inserted into the nib 5, and both of them have a cross-sectional shape of the nib 1 and the shape of the tip 2 in contact with the tip type. Same as the example.

However, in the case of the pen body of FIG. 8, the ink groove 3 is formed to the rear end through the plain thread portion 5a, and the air groove 11a is separately laid in the relationship between the pen core and the pen.

Also in the case of the fin body of FIG. 9, the ink groove 3 and the air groove 11a are provided similarly to this.

The plastic pen body of the present invention has an angle of 45 degrees to 65 degrees in which the nib 1 has a pointed back surface, the abdomen has a triangular cross-sectional shape, and the tip paper contacting portion 2 is adapted to the writing angle as described above. At the same time as forming the θ and cutting the ink groove 3 to allow the ink to flow to the tip end portion, the pen tip 1 is cut out so that it does not fall off, and the tip contact portion 2 is rented on the ground. If the pen pressure is used as the pusher, the pen tip (1) bends well like the tip of the brush by its elasticity, and then it is restored. It is written well like a brush.

In addition, the pen body of the present invention is directional at the time of writing, and unlike the brush, it does not spread or crush, so anyone can easily use it, such as writing a fountain pen, and the cost is low because the molding is simple. There is this.

Claims (1)

In the pen body which is molded by elastic plastic and directional in writing, the nib part 1 has the back part pointed and the abdomen part in a flat triangular cross-sectional shape, and the tip paper contact part 2 is suitable for the writing angle. A plastic pen body, formed at an angle θ of 45 degrees to 65 degrees, and provided with an ink groove (3) on the pen body portion in which the nib portions are cut away from each other so that ink flows into the contact portion of the tip paper.
