    • On both cap and tubular sheath are formed sealing fit portions for sealing between a writing tip and a front-end opening of the tubular sheath and also formed override fit portions for preventing dislodgement of the cap from the tubular sheath in such a manner that their sealing fit motion and override fit motion start simultaneously at the time of mounting of the cap, whereby the loading on a finger tip in the course of mounting the cap is only once. The outer surface of the cap is integrally provided with a clip which is wider than a connecting leg portion for connection with the cap and which defines an air flow gap extending from the clip head including the connecting leg portion up to the opening portion. Further, on both sides of the connecting leg portion are formed longitudinal grooves extending continuously in parallel from the head portion toward the opening portion so that even in the event of swallowing the cap there can be ensured a wider and fully sufficient air flow area with more safety by the air flow gap formed between the outer surface of the cap and the clip and also by the two longitudinal grooves.
    • 在盖和管状护套上形成密封配合部分,用于在书写尖端和管状护套的前端开口之间进行密封,并且还形成用于防止帽从管状护套脱出的超越配合部分,使得它们的密封 在安装帽时同时启动适配运动和超驰配合运动,由此在安装盖子的过程中指尖上的负载仅为一次。 盖的外表面一体地设置有夹子,该夹子比用于与盖连接的连接腿部部分宽,并且限定从包括连接腿部的夹头延伸到开口部分的气流间隙。 此外,在连接腿部的两侧形成有从头部朝向开口部分平行延伸的纵向槽,使得即使在吞咽帽的情况下,也可以确保更宽且充分充分的空气流动区域,具有更多 通过在盖的外表面和夹子之间以及由两个纵向槽形成的气流间隙的安全性。

    • The subject of the invention is to provide a knock-type writing instrument in which a cloth can be prevented from being stained by the clip releasing mechanism having a compact structure when the writing instrument is stored in a pocket and further the writing extremity end can be prevented from being damaged under the projected state by an unintended use of it. The window hole is formed at the peripheral surface of the barrel, the ball section of the clip is provided with the inner protrusions which can be extended or retracted into said window hole, the rotor is provided with a plurality of peripheral protrusions at the outer peripheral surface in a circumferential direction so as to stop the rotor by being abutted against said inner protrusions of the clip when said extremity end is projected, the inner protrusions of the clip are moved toward an outer side of the shaft as the clip is opened when said extremity end is projected, resulting in that the protrusions are not abutted against the peripheral protrusions of the rotor and then the rotor is rotated to cause the writing extremity end to be retracted into the barrel.
    • 本发明的目的是提供一种敲击式书写工具,其中当书写工具储存在口袋中时,可以防止布料被具有紧凑结构的夹子释放机构染色,并且进一步的书写末端可以是 防止在预计状态下由于意外使用而被损坏。 窗口孔形成在筒体的周面,夹子的球部设置有能够延伸或缩回到所述窗孔中的内部突起,转子在外周设有多个周边突起 在圆周方向上表面,以便当所述末端伸出时通过抵靠夹子的所述内部突起来停止转子,当所述夹子的所述前端突出时,夹子的内部突起在夹子被打开时朝向轴的外侧移动 突出端部,导致突起不抵靠转子的周边突起,然后使转子旋转,使书写端部端部缩回到筒体内。

    • A writing tool including: a cylindrical shell containing ink of a solid-liquid separation type and a stirring piece; an ink flow-out control mechanism disposed in the cylindrical shell, which includes a valve main body having an ink introducing port around the peripheral surface thereof, and a valve which is contained in the valve main body in such a manner as to freely advance and retreat and which is biased in the valve closing direction by a coil spring; and a writing tool mounted to the cylindrical shell through the ink flow-out control mechanism; wherein an enclosed ink containing cylindrical body having a suitable length and diameter is disposed in the cylindrical shell; the ink and the stirring piece are contained in the ink containing cylindrical body; and an ink flow-out port for supplying the ink from the ink containing cylindrical body into an ink introducing port of the valve main body is formed at a suitable portion of the ink containing cylindrical body.
    • 一种书写工具,包括:包含固液分离型油墨和搅拌片的圆柱形壳体; 设置在所述圆筒形壳体中的墨水流出控制机构,其包括具有围绕其外周表面的墨水引入口的阀主体和以自由推进方式包含在所述阀主体中的阀, 并且通过螺旋弹簧在阀关闭方向上偏置; 以及通过墨水流出控制机构安装到圆筒形壳体上的书写工具; 其中在所述圆筒形壳体中设置具有适当长度和直径的封闭油墨容纳圆筒体; 油墨和搅拌片被包含在含油墨筒体中; 并且在墨水容纳圆柱体的适当部分形成有用于将墨水从墨水容纳圆筒体供给到阀主体的墨水引入口中的墨水流出口。
