Abstract

(57) [Abstract] [Purpose] It is a fountain pen that has a pen tip that can be manufactured at low cost by pressing, and is applicable to thick strokes, fills and underlines. [Structure] Folded face to face, with the bent portion 5 as the writing tip portion 7, both side surfaces are tapered along the tip portion,
It has a pen tip 4 made of a metal plate piece having a slit 6 formed substantially on the center line toward the writing tip portion 7, and a slit-shaped ink guide groove is provided in the middle of the plate piece portion facing the pen tip 4. Support part 8 that is in close contact with the writing tip part 7
Is provided and fixed to the tip of the barrel, the ink flow rate adjusting unit and the ink are stored in the barrel so that the ink can be led to the writing tip.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of a pen tip used for a fountain pen or the like.

[0002]

[Prior Art]

 A conventional nib used for a fountain pen or the like is generally known in which gold, iridium, or the like is attached to the tip by a method such as welding.

[0003]

[Problems to be solved by the device]

 The conventional nibs used for fountain pens and the like cannot be applied to the pen tips of fountain pens and the like which are expensive and inexpensive because of the use of precious metals and the processing steps. The purpose of the present invention is to make it possible to provide an inexpensive pen tip for a fountain pen under the circumstances, and to use it as a fountain pen suitable for thick writing lines, filling and underlining, and using an underline using a conventional sliver core The purpose of the marker is to make it reusable, while the marker is disposable because it becomes unusable when the pen tip is worn or deformed, or when it is dried up.

[0004]

[Means for Solving the Problems]

 The pen tip of the fountain pen of the present invention devised to achieve the above-mentioned object is formed by pressing a stainless steel plate material toward the center in a tapered shape and a substantially symmetrical shape, and is bent at the center to face each other. However, a slit is formed toward the tip with the bent portion as the writing tip. The pen nib is fixed to the tip of the barrel by mounting a supporting part with a slit-shaped ink guide groove in the middle of the facing plate piece in close contact with the tip of the writing. It is configured to be connected to the support part on the front side and to store the ink on the ink flow rate adjusting part and on the rear side so that the ink is led out to the writing tip part.

[0005]

Embodiments FIGS. 1 to 5 show an embodiment of the present invention. First, as shown in FIG. 1, the pen tip 4 is formed by pressing a plate material such as stainless steel into a tapered shape that is substantially symmetrical toward the center, and is bent at the bent portion 5 at the center to face each other. A writing tip 7 is provided. Further, a slit 6 is formed substantially on the center line toward the writing tip portion 7, and a slit shape or an ink guide core (not shown) is provided in the middle of the opposing plate pieces so as to be close to the writing tip portion 7. The support portion 8 is provided up to and fixed to the tip of the tip shaft 3. Further, an ink flow rate adjusting portion (not shown) is provided in the front shaft 3 so as to be connected to the support portion 8, and the rear shaft 2 is attached to the rear end of the front shaft 3 by screwing or the like. In addition, an ink cartridge (not shown) in which ink is stored is installed in the rear shaft 2 so as to face the rear end of the ink flow rate adjusting unit, and the ink is guided to the writing front end. There is. That is, the barrel is composed of the front shaft 3 and the rear shaft 2.

[0006]

[Effect of the device]

 The structure of the present invention is as described above, and it is possible to mass-produce inexpensively by pressing using noble metal such as gold and iridium like a conventional nib and eliminating the troublesome process such as welding. It becomes possible to use it for the pen tip of an inexpensive fountain pen. In addition, it is more rigid and less prone to damage than conventional pen nibs, and its rounded tip makes it easy to write on, has a thick line, and is suitable for filling and underlining. Therefore, the underline marker that used the conventional sliver core cannot be used due to abrasion, crushing, and dry-up of the pen core, so it is a disposable type, but it can be reused by filling it with ink. There is.
