Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案は万年筆、マーキングペン等のペン先に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a pen tip such as a fountain pen and a marking pen.
筆記具のペン先は、滑らかな書き味が得られ、耐摩耗性
に優れ、且つ、複写書きが可能であることが好ましい。It is preferable that the pen tip of the writing instrument has a smooth writing feel, is excellent in abrasion resistance, and is capable of writing by copying.
従来の万年筆のペン先は、前二者の要請を満たすが、複
写書きができず、また、比較的高価であるという欠点が
あり、マーキングペンのペン先は、経済的には有利であ
るが、耐摩耗性に欠け、複写書きができないという欠点
がある。そこでこれらの欠点をカバーするためにセラミ
ック製のペン先が提唱された。Although the fountain pen nib of the related art meets the requirements of the former two, it has the drawback that it cannot be copied and written and is relatively expensive, and the nib of the marking pen is economically advantageous. However, it has a drawback that it lacks abrasion resistance and cannot be copied. Therefore, a ceramic nib was proposed to cover these drawbacks.
従来のセラミック製ペン先は、中継芯を挿入するための
通路を抉り設けなければならず、どうしても製造コスト
が割高となってしまう。The conventional ceramic nib has to be provided with a passage for inserting the relay core, which inevitably increases the manufacturing cost.
従って本考案の課題は、上述したペン先に対する要請を
すべて満たし、しかも製造容易で、比較的廉価にて供給
し得るペン先を提供せんとするところにある。SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a pen tip that satisfies all the above-mentioned requirements for the pen tip, is easy to manufacture, and can be supplied at a relatively low cost.

題を解決した。[Means for Solving the Problem] The present invention is composed of two semi-cylindrical ceramic bonding members of the same shape, and a cylinder into which a relay core is fitted by bonding the bonding members. -Shaped core holding portion is formed, and the tip end of each of the coalescing members is a hemispherical writing part that is squeezed, and the facing surface of each of the coalescing members is in contact with each of the coalescing members. The above-mentioned problems are solved by a pen tip formed by providing a step on the surface, and thus forming an ink seeping slit communicating with the inside of the lead holding portion between the facing surfaces.
同一形状の合着部材を合着することにより、中継芯を挿
入する芯保持部とスリットが形成される。By joining the joining members having the same shape, the lead holding portion for inserting the relay lead and the slit are formed.

Reference numeral 2 denotes a ceramic bonding member of the same shape, each having a semi-cylindrical shape, and by bonding them, a cylindrical core holding portion 3 for inserting and inserting a core is formed. Reference numeral 4 is a writing portion formed by squeezing the tips of the coalescing members 1 and 2, and serves as a slit 5 that holds a gap between the coalescing member 1 side and the coalescing member 2 side to allow ink to seep out. That is, the facing surfaces of the writing unit 4 on the side of the coalescing member 1 and the side of the coalescing member 2, respectively,
It is formed by providing a step on the contact surface of No. 2. By doing so, the slit 5 communicating with the inside of the lead holding portion 3 at the time of attachment is formed. Reference numeral 6 denotes a relay core fitted and inserted in the core holding portion 3, and may be inserted in the core holding portion 3 in a state where it is fitted and inserted in the core tube 7 as shown in FIG. Reference numeral 8 denotes a tip end portion of the shaft cylinder into which the joining members 1 and 2 are fitted in a joined state.

揮しうる効果がある。The present invention is as described above, can be manufactured easily and inexpensively, and, because it is made of ceramic, has any of hardness, strength, surface roughness, abrasion resistance, corrosion resistance, and color freedom. It is also excellent in that it has a smooth writing feel and is free to copy and write, and has the effect of withstanding a little rough handling and writing pressure and exhibiting the same writability as the original for a long time.
