Abstract: PURPOSE: A tip for ball point pen is provided to increase the discharge amount of ink according to the increase of forward and backward flow interval. CONSTITUTION: A ball(101) is formed in a sphere shape. The front end side of a tip body(110) is formed in a circular cone shape. A ball house(112) is formed at the end portion of an ink outflow path(111). A part of the ball is exposed to the ball house. A ball support portion is formed by the shutting of a front end part(114) so that the ball is supported in the state where the ball is exposed. The outer circumference of the front end part for the formation of the ball support portion of the tip body sets a taper angle in a range of 3~10°.
Abstract translation: 目的：提供圆珠笔尖，根据正向和反向流动间隔的增加增加墨水的排放量。 构成：球（101）形成为球形。 尖端体（110）的前端侧形成为圆锥形状。 在墨水流出路径（111）的端部形成球室（112）。 球的一部分暴露在球室。 通过关闭前端部（114）形成球支撑部，使得球以暴露的状态被支撑。 用于形成尖端体的球支撑部的前端部的外周将锥角设定在3〜10°的范围内。

Abstract: PURPOSE: A free ink type ballpoint pen refill is provided to evenly mix an ink composite using a mixing member when an coloring agent including metallic or the titanium oxide with a heavy specific gravity is precipitated. CONSTITUTION: A free ink type ballpoint pen refill comprises: an ink storage pipe; a writing tip(16) which is combined on tip-end part of the ink storage pipe and in which a ball is rotatably assembled; an ink composite(20) saved inside the ink storage pipe; and an ink follower(22) which blocks a rear part of the ink storage pipe and moves to the writing tip side as storage quantity of the ink composite diminishes. A viscosity of the ink composite is 5~1000mPa.s(B type Viscometer, and 20°C) and a stirring member(30) is installed inside of the ink composite.
Abstract translation: 目的：提供一种自由的墨水圆珠笔笔芯，以便当包含金属或重比重的氧化钛的着色剂沉淀时，使用混合构件均匀地混合墨水复合材料。 构成：自由墨水圆珠笔笔芯包括：墨水储存管; 书写尖端（16），其组合在储墨管的前端部分上，其中可转动地组装球; 储存在储墨管内的油墨复合材料（20）; 以及墨水随动体（22），其阻止墨水储存管的后部并随着墨水复合物的储存量的减少而移动到书写尖端侧。 油墨复合体的粘度为5〜1000mPa.s（B型粘度计，20℃），搅拌部件（30）安装在油墨复合体的内部。
