摘要： A penpoint assembly includes a penpoint which is made of a metal plate cut off at both side edges to form a taper toward the writing tip. A slit is provided extending from the front end of the writing tip to the vicinity of the rear end of the writing tip along the center line of the penpoint. The penpoint is bent at the writing tip to form small bent projections at both sides of the slit, the bent portion surrounding a small space. An ink guide core extends under the slit and communicates at the tapered portion of the ink guide core with the slit. A support member supports the ink guide core and penpoint. A writing instrument includes the penpoint assembly, the support member being integrally formed with an ink flow regulating portion, so that ink in an ink storage member in the rear portion of a penholder is guided to the writing tip through the ink guide core.
摘要翻译：笔尖组件包括由在两个侧边缘处切断的金属板制成的笔尖以朝向书写尖端形成锥形。从笔尖的前端沿着笔尖的中心线向笔尖的后端附近设置狭缝。笔尖在书写尖端处弯曲，以在狭缝的两侧形成小的弯曲突起，弯曲部分围绕着小的空间。墨水导向芯在狭缝的下方延伸，并在墨水导向芯的锥形部分与狭缝连通。支撑构件支撑墨水导向芯和笔尖。书写工具包括笔尖组件，支撑构件与油墨流动调节部分整体形成，使得笔筒后部的墨水容纳构件中的墨水通过墨水导向芯被引导到笔尖。

摘要： In a liquid-applying tip assembly in which the liquid-applying member is pushed to operate the valve to allow the liquid to flow to the liquid-applying member, the liquid-applying member is a plastic member which comprises: a plurality of ribs extending radially and axially from an axial core in such a manner as to form a plurality of axial liquid passageways therebetween. A barrier is provided between the valve and the cylinder of the tip assembly, the barrier having a hole whose diameter is slightly larger than the outside diameter of the liquid-applying member to control the flow of liquid.

摘要： Ink and a follower advancing with consumption of the ink are stored directly in the inside of a barrel having a pen point at its forward end. An outer tail plug constituted by a closed-end cylinder is fitted to a rear outer surface of the barrel. An air course is formed between the rear outer surface of the barrel and an inner surface of the outer tail plug to communicate with the inside of the barrel through a rear end aperture portion of the barrel. At least one air hole is provided ahead of the rear end aperture portion of the barrel to make the air course communicate with the outside air.

摘要： A ball-point pen tip provided with a tubular ink guide portion formed of metal. The ink guide portion is formed with radial projections extending radially inwardly produced by the pressing deformation of the metal tube. These projections define capillary channels between neighbouring projections and a ball seat at their radially oriented surfaces. An ink guide stem disposed in the tubular ink guide portion has one end in contact with at least one of the projections, and has the other end confronting with an ink supply stem inserted in a holder. The holder and the ink guide portion provide a socket of the pen tip. Such pen tip is applied to a ball-point pen which includes an ink reservoir adapted to be connected to said ink supply stem. Such ball-point pen employs an aqueous solution based low viscosity ink.
摘要翻译：一种圆珠笔笔尖，设有由金属形成的管状墨水引导部分。墨水引导部形成有径向向内延伸的径向突出部，其通过金属管的挤压变形而产生。这些突起在其径向定向的表面处限定相邻突起和球座之间的毛细通道。设置在管状墨水引导部分中的墨水导向杆具有与至少一个突起接触的一端，并且另一端面对插入在支架中的供墨杆。保持器和墨水引导部分提供笔尖的插座。这种笔尖被应用于包括适于连接到所述供墨杆的墨水贮存器的圆珠笔。这种圆珠笔采用基于水溶液的低粘度油墨。
