Abstract

(57) [Summary] [Purpose] Consume a large amount of ink during writing, such as when writing large characters with thick handwriting in a state where the ink is bleeding on paper with large ink absorption, such as Japanese paper and half-paper. We will provide fountain pen nibs that can follow the ink supply and can be used for writing. [Structure] The tip portion where the ink groove 2 is cut is made thicker, or a laminated plate 5 is attached to the base plate 1 portion at the tip to make it thicker, and further, an ink groove is formed between the original plate and the laminated plate. An ink holding gap 6 that communicates with the ink is provided to increase the amount of ink held in the pen tip so that the ink supply can follow the large consumption of ink.

Description

Detailed Description of the Invention

The present invention relates to a pen tip for a fountain pen.

[0002]

2. Description of the Related Art A pen tip for a fountain pen is made of a metal plate made of stainless steel or a gold alloy and having a thickness of about 0.3 mm, and has a substantially arc-shaped cross section and a substantially triangular tip. , Has a well-known shape. An ink groove having a predetermined length is cut from the tip, and a ball made of cemented carbide is welded to the tip. The pen tip is attached to the tip of a fountain pen together with a pen core having a function of preventing ink from dripping, and the ink of the pen core supplied from the ink cylinder is transmitted to the ink groove of the pen tip and used for writing. Then, when a large writing pressure is applied, the tip portion bends to widen the ink groove, and characters can be written with a thick handwriting.

[0003]

As described above, the pen tip for a fountain pen has an advantage that the thickness of the handwriting can be adjusted according to the magnitude of the writing pressure. Therefore, sometimes on large-ink-absorbing paper such as Japanese paper or half-paper, large characters are written with thick handwriting in which the ink is bleeding into the paper, and it looks like a character written with a brush. In this case, the amount of ink consumed is naturally high. However, the amount of ink supplied to the paper surface with high ink absorption is small because the ink is held in the ink groove of the pen tip by capillary force, and there is a problem that the ink supply cannot follow the large consumption of ink. .

Therefore, the present invention consumes a large amount of ink at the time of writing, such as when writing a large character with a thick handwriting in a state where the ink is bleeding on the paper having a large ink absorption capacity such as Japanese paper or half-paper. In this case, it is also an object of the present invention to provide a fountain pen nib capable of following ink supply and writing.

[0005]

In order to achieve such an object, the present invention provides a fountain pen nib in which an ink groove having a predetermined length is cut from the tip, and a tip portion in which the ink groove is cut is provided. To make it thick, or to attach a laminated plate to the base plate part of the tip where the ink groove is cut to make it thick,
Increases the amount of ink retained in the ink groove.

Alternatively, an ink-holding gap communicating with the ink groove is provided between the base plate and the mating plate to increase the amount of ink held by the pen tip.

[0007]

Action: That is, in the fountain pen nib, the tip portion where the ink groove is cut is made thicker, or the base plate portion of the tip is laminated with a laminated plate to make it thicker. An ink-holding gap that communicates with the ink groove is provided between the mating plates to increase the amount of ink held by the pen tip, so that you can follow the ink supply even when a large amount of ink is consumed during writing, enabling writing. Become.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to the embodiments shown in the drawings. FIG. 1 shows a plan view of an embodiment of the present invention. The planer shape of the fountain pen nib of the present invention is almost the same as that of a known fountain pen nib. That is, the plate thickness is 0.3
The base plate 1 made of a stainless steel plate of mm has a substantially arcuate cross section, and its tip has a triangular shape. Then, a ball 3 made of cemented carbide is welded to the tip, and the ink groove 2 having a predetermined length is cut and cracked from the tip.

Here, the portion where the ink groove 2 is cut and cut at the tip of the base plate 1 has a thick plate thickness, and constitutes a thick portion 4. As shown in FIG. 2, the plate thickness is thicker toward the tip, and the wall thickness in the vicinity of the ball 3 is 1.25 mm. Therefore, the area of the ink groove 2 is much larger than that of the conventional fountain pen tip, and the area of the ink groove 2 is larger toward the tip.

To form the thick portion 4, as shown in FIG. 3, a laminated plate 5 may be attached to the base plate 1 having a uniform plate thickness. At this time, a gap 6 communicating with the ink groove 2 is provided between the base plate 1 and the mating plate 5, the ink supplied to the ink groove 2 or the ink is held in the gap 6, and the ink groove 2
It is preferable that the ink in the gap 6 is supplied to the ink groove 2 when the above ink is consumed.

The fountain pen nib having such a structure is attached to the tip of the fountain pen together with the pen core having a function of preventing ink from dripping, but the ink of the pen core supplied from the ink cylinder is transmitted to the ink groove 2. Be used for. At this time, the ink held in the ink groove 2 or the ink groove 2 including the gap 6 is much larger than that of the conventional fountain pen nib, so that it can be used on paper with large ink absorption, such as Japanese paper or half-paper. Even when a large amount of ink is consumed, such as when writing a large character with a thick handwriting in a state where the ink is bleeding on the paper, the ink supply follows and it is possible to write.

[0012]

As described above, in the fountain pen nib of the present invention, the tip portion where the ink groove is cut is made thick, or the base plate portion of the tip where the ink groove is cut is laminated with the laminated plate. To increase the amount of ink held in the pen tip by providing a gap between the base plate and the laminated plate that can hold ink and communicates with the ink groove.
Even when a large amount of ink is consumed during writing, such as when writing large characters with thick handwriting where the ink is bleeding onto the paper that has a high ink absorption capacity such as Japanese paper or half-paper, the ink supply follows. It can be used as a fountain pen tip that can be written.
