    • PROBLEM TO BE SOLVED: To provide a liquid supply tool capable of reliably forming an air hole, and capable of smoothly supplying a liquid.SOLUTION: The tool is provided, in an outer cylinder 12, with a liquid retaining unit 20 for retaining a liquid, and a liquid supply body 30 which projects from the liquid retaining unit 20 toward a tip end opening 18a of the outer cylinder 12 and is capable of guiding the liquid within the liquid retaining unit 20 to the outside through the tip end opening 18a. The liquid supply body 30 comprises a core 32 for guiding the liquid, and an outer casing 34 provided around the core 32. The core 32 and the outer casing 34 are integrally formed, the outer casing 34 surrounds the external circumference of the core 32 from the tip end portion of the core 32 to the liquid retaining unit 20, and at least one air hole 34a is formed within the cylindrical wall of the outer casing 34 so that the air hole 34a extends from the tip end side of the core 32 to the inside of the liquid retaining unit 20 by penetrating in the axial direction.
    • 要解决的问题:提供能够可靠地形成空气孔并且能够平稳地供应液体的液体供给工具。 解决方案:工具在外筒12中设置有用于保持液体的液体保持单元20和从液体保持单元20朝向外部的顶端开口18a突出的液体供应体30 并且能够通过顶端开口18a将液体保持单元20内的液体引导到外部。 液体供应主体30包括用于引导液体的芯32和围绕芯32设置的外壳34.芯32和外壳34一体形成,外壳34围绕芯32的外周围 在外壳34的圆筒壁内形成有芯32的前端到液体保持单元20的至少一个气孔34a,使得空气孔34a从芯32的顶端侧延伸到 液体保持单元20的内部沿轴向穿透。 版权所有(C)2012,JPO&INPIT

    • PROBLEM TO BE SOLVED: To form a nib among parts which constitute a writing utensil, with a synthetic resin material employing engineering plastic.SOLUTION: An ink supply wick 39 includes a wick cover 49. An outer shape of a wick cover 49 is determined such that it is attached to an outer periphery of the ink supply wick 39 between the nib 1 and the ink supply wick 39 and is made to closely adhere to an inner periphery of the nib 1 at least at the tip of the nib 1. A space between the nib 1 and the ink supply wick 39 is filled with the wick cover 49. The nib is made of the synthetic resin material employing the engineering plastic. Therefore, the nib wear resistance and duration of the nib or the writing utensil can be extended.
    • 要解决的问题:在使用工程塑料的合成树脂材料上形成构成书写用具的零件之间的笔尖。 油墨芯39包括油芯盖49.油芯盖49的外部形状被确定为使得其附接到笔尖1和墨水供墨芯之间的墨水供应芯39的外周边 并且至少在笔尖1的尖端处紧密地附着到笔尖1的内周。笔尖1和墨水供墨芯39之间的空间被芯盖49填充。笔尖由 使用工程塑料的合成树脂材料。 因此,可以延长笔尖或书写工具的笔尖耐磨性和持续时间。 版权所有(C)2013,JPO&INPIT
