    • PROBLEM TO BE SOLVED: To stabilize the behavior of air inside an ink tank. SOLUTION: The refill of a low-viscosity aqueous ball-point pen comprises a housing, a pen point fitted to the apex of the housing, an ink tank 4 formed inside the housing, an ink guidance member which guides the internal ink of the ink tank 4 to the pen point, and an air passageway which is formed inside the housing between the ink tank 4 and the pen point and connects the ink tank 4 with the outside of the housing. The ink tank is internally divided into a plurality of ink chambers arranged longitudinally by a partition wall 11, and the internal ink of the these ink chambers is guided successively to the pen point, to begin with, from the ink chamber closest to the pen point. In addition, an almost uniform clearance 13 is provided across the entire circumference of the ink tank 4 between the outer peripheral surface of the partition wall 11 and the inner peripheral surface of the ink tank 4. Further, the ink is retained inside the ink chamber by an annular ink liquid film formed in the clearance 13, so as to allow the inflow of air into the ink chamber through the clearance 13.

    • 要解决的问题:稳定墨水罐内空气的行为。 解决方案:低粘度水性圆珠笔的再填充物包括壳体,装配到壳体的顶点的笔尖,形成在壳体内部的墨水罐4,引导内部墨水的墨水引导构件 墨盒4到笔尖的空气通道,以及形成在墨盒4和笔尖之间的壳体内的空气通道,并将墨盒4与壳体的外部连接。 墨盒内部被分隔成由分隔壁11纵向布置的多个墨室,并且这些墨室的内部墨水被连续地引导到笔尖,从最接近笔尖的墨室开始 。 此外,在分隔壁11的外周表面和墨水罐4的内周表面之间,在墨水罐4的整个圆周上提供几乎均匀的间隙13.此外,墨水保持在墨水室内 通过形成在间隙13中的环形油墨液膜,以便允许空气通过间隙13流入墨室。版权所有(C)2008,JPO&INPIT
