Description

本発明は、軸筒にシール、印刷等の表示部を施した筆記具に関する。 The present invention relates to a writing instrument in which a shaft cylinder is provided with a display unit such as a sticker or printing.

従来より、筆記具においては、軸筒に印刷等の表示部を施すことで、装飾性の向上や筆記具の識別を容易にしている。 Conventionally, in a writing instrument, a display unit such as printing is provided on the shaft cylinder to improve the decorativeness and facilitate the identification of the writing instrument.

また、特許文献1〜3に示されるように、筆記具のクリップ、軸筒、インク収容管などの筆記具用部材の好適な箇所に文字、図形などの表示部をシールや刻印などで施し、シール等の表示位置を容易にし、軸筒のどこに表示部があるかの視認性を向上させている。 Further, as shown in Patent Documents 1 to 3, display parts such as characters and figures are attached to suitable parts of writing instrument members such as writing instrument clips, shaft cylinders, and ink storage tubes with stickers, engravings, etc., and the seals, etc. The display position of the ink is facilitated, and the visibility of where the display unit is located on the barrel is improved.

しかしながら、特許文献1〜3に示された技術は、いずれもボールペンであり、筆記部が径方向に対して非対称形状である場合は、軸筒と筆記部との回転位置がずれることがあり、軸筒に印刷等の表示を施した製品によっては、使用時における軸筒の表示位置が異なることがあり、ユーザーによっては使用感を損なうおそれがあるなどの課題がある。 However, the techniques shown in Patent Documents 1 to 3 are all ballpoint pens, and when the writing portion has an asymmetrical shape with respect to the radial direction, the rotational positions of the barrel and the writing portion may shift. Depending on the product on which the display such as printing is applied to the shaft cylinder, the display position of the shaft cylinder at the time of use may be different, and there is a problem that the usability may be impaired depending on the user.

In addition, only the visible portion 43 may be made of a material having visibility.
Further, the holding body 40 may be formed by using one type of each of the above materials, or two or more types of materials from the viewpoint of further improving durability and visibility, injection molding, blow molding and the like. It can be molded by various molding methods of.
In the writing tool A, the holding groove 46 has side holding grooves 46a and 46a and a front holding groove 46b for securely fixing the pen core 35, and when the pen core 35 is fitted into the holding groove 46. , The pen core 35 penetrates strongly into the holding groove 46 from the bottom surface side of the ink guiding portions 36, 36, and the pen core 35 is securely fixed to the holding groove 46 of the holding body 40. In the present embodiment, in order to prevent the writing body 37 from being displaced during writing or the like on the front surface portion 47b of the holding groove 46, which is a portion of the pen core 35 that comes into contact with the writing body 37, and to ensure holding. A non-smooth surface portion 47 having a concavo-convex shape is formed. In addition, in order to ensure the fixing of the pen core 35, an adhesive such as a hot melt type or ultrasonic welding may be used.

このペン芯35を固定した保持体40(図5)から構成される筆記部50は、図5等に示すように、非対称形状の筆記部となるものであり、この筆記部50における保持体40を、先軸20の開口部20内に圧入すると、先軸20の嵌合部23に保持体40の嵌合部41aが嵌合することにより、ペン芯35は保持体40を介して筆記具軸筒10に固着され筆記部50と軸筒10とは相対回転不能となると共に、ペン芯35のインク誘導部36,36の後方側端部36a、36aはインク吸蔵体30の先端側内部に入り込む構成となっている。なお、インク吸蔵体30の先端側内部にインク誘導部35,35の後方側端部36a、36aを挿入する凹部を形成してもよい。また、軸筒10内の圧力等が増大にした際に、インク垂れ等がペン先から生じることがあるが、本実施形態の筆記具Aでは、空気流通溝41bを介して軸筒10内と外気とを調整している。
キャップ60は、先軸20の先端側外周面に嵌合等により着脱自在に取り付けられるものである。キャップ60は、不透明の材料にて成形されるが、キャップ60の外から筆記部50を視認できるよう透明(又は半透明)な材料で成形してもよい。
As shown in FIG. 5 and the like, the writing unit 50 composed of the holding body 40 (FIG. 5) to which the pen core 35 is fixed is an asymmetrical writing unit, and the holding body 40 in the writing unit 50 Is press-fitted into the opening 20 of the toe shaft 20, and the fitting portion 41a of the holding body 40 is fitted to the fitting portion 23 of the toe shaft 20, so that the pen core 35 is inserted into the writing instrument shaft via the holding body 40. The writing portion 50 and the shaft cylinder 10 are fixed to the cylinder 10 so that they cannot rotate relative to each other, and the rear end portions 36a and 36a of the ink guiding portions 36 and 36 of the pen core 35 enter the inside of the tip side of the ink storage body 30. It is composed. It should be noted that a recess may be formed inside the tip side of the ink storage body 30 into which the rear end portions 36a, 36a of the ink guiding portions 35, 35 are inserted. Further, when the pressure in the barrel 10 increases, ink dripping or the like may occur from the pen tip, but in the writing tool A of the present embodiment, the inside of the barrel 10 and the outside air pass through the air flow groove 41b. And are adjusting.
The cap 60 is detachably attached to the outer peripheral surface on the tip end side of the toe shaft 20 by fitting or the like. Although the cap 60 is molded of an opaque material, it may be molded of a transparent (or translucent) material so that the writing portion 50 can be visually recognized from the outside of the cap 60.

本発明となる筆記具Aでは、筆記具の軸筒10内に筆記具用インクを吸蔵したインク吸蔵体30を挿入して保持せしめ、先軸20、ペン芯35を嵌入保持等により固定した保持体40を順次嵌合等により固着せしめることにより、筆記部50と軸筒10とは相対回転不能となり、簡単に筆記具Aを作製することができ、インク吸蔵体30に吸蔵されたインクは毛管力によりペン芯35の筆記体37に効率的に供給され、図7に示す態様で、筆記に供されるものとなる。 In the writing instrument A according to the present invention, the ink storage body 30 that stores the ink for the writing instrument is inserted into the shaft cylinder 10 of the writing instrument and held, and the holding body 40 in which the tip shaft 20 and the pen core 35 are fixed by fitting and holding is provided. By sequentially fitting and fixing them together, the writing unit 50 and the barrel 10 cannot rotate relative to each other, and the writing instrument A can be easily manufactured. The ink stored in the ink storage body 30 is a pen core due to the capillary force. It is efficiently supplied to the writing body 37 of 35 and is provided for writing in the manner shown in FIG.

このように構成される筆記具Aでは、非対称形状の筆記部50を有し、筆記部50が取り付けられる軸筒10には、径方向断面に非正円形状部分を有し、筆記部50と軸筒10とは相対回転不能であることから、非対称形状のペン先となる筆記部50の向きと軸筒10の印刷等の表示部19の向きを一定方向に配置できることから、使用時における軸筒10の印刷方向を安定させることができ、使用感の向上を図ることができる。また、軸筒10は印刷等だけでなく、握り形状等とすることも可能となる。
また、軸筒10の後端面には、非正円形状の穴18を形成することにより、成形時のゲート部と筆記部50との位置決めが容易となる。更に、軸筒10内には上述のリブ体17、17が形成されているので、インク吸蔵体(中綿)30の位置安定と、印刷位置の安定を図ることができることとなる。
更に、本発明の筆記具Aは、上述の如く、ペン芯35を固着した保持体40が、視認性を有する材料で構成されているので、当該保持体40の可視部43が、筆記方向を視認できる視認部となるものであり、筆記方向に書いてある文字を確実に読むことができる十分な視認性が付与することができると共に、終筆まで使用可能な筆記具が提供されるものとなる。
The writing instrument A configured in this way has an asymmetrically shaped writing portion 50, and the barrel 10 to which the writing portion 50 is attached has a non-circular portion in the radial cross section, and the writing portion 50 and the shaft. Since the cylinder 10 cannot rotate relative to the cylinder 10, the direction of the writing portion 50, which is an asymmetrical pen tip, and the orientation of the display portion 19 for printing, etc. of the shaft cylinder 10 can be arranged in a fixed direction. The printing direction of 10 can be stabilized, and the usability can be improved. Further, the barrel 10 can be formed not only by printing but also by a grip shape or the like.
Further, by forming a non-circular hole 18 on the rear end surface of the barrel 10, the gate portion and the writing portion 50 can be easily positioned at the time of molding. Further, since the rib bodies 17 and 17 described above are formed in the barrel 10, the position of the ink storage body (filling) 30 can be stabilized and the printing position can be stabilized.
Further, in the writing tool A of the present invention, as described above, the holding body 40 to which the pen core 35 is fixed is made of a material having visibility, so that the visible portion 43 of the holding body 40 can visually recognize the writing direction. It is a visible part that can be provided, and it is possible to provide sufficient visibility that can reliably read characters written in the writing direction, and a writing tool that can be used until the end of writing is provided.
