    • A lead cartridge that is provided with a tank part for storing leads and is capable of being detachably connected to a receiving part provided in a lead feeding mechanism of a mechanical pencil to supply a lead can reduce costs for manufacturing the lead cartridge and the number of manufacturing steps and can prevent a lead from falling out from the lead cartridge inadvertently.
      The lead cartridge 10 includes a case 12 and a swing cover 14. A tank part 12a is defined inside the case 12 and the tip end part of the case 12 is formed with an open tip end connection part 12b. Between the tank part 12a and the tip end connection part 12b, a lead port 12e is formed. The swing cover 14 is mounted in the case 12 swingably to a closing position where the swing cover 14 closes the lead port 12e and to an opening position where the swing cover 14 opens the lead port 12e. The swing cover 14 includes an interfered part 14c capable of being interfered with an interference part 46e of a cartridge receiving part 46b of the mechanical pencil. The swing cover 14 is biased in a swing direction from the opening position to the closing position but swings from the closing position to the opening position when the tip end connection part 12b is fitted with the cartridge receiving part 46b so as to cause the interfered part 14c to be interfered with the interference part 46e.
    • 一种引线盒,其具有用于存储引线的容器部分,并且能够可拆卸地连接到设置在自动铅笔的引线馈送机构中的接收部分以提供引线可以降低制造引线盒的成本和数量 制造步骤,并且可以防止铅不经意地从铅盒中脱落。 引线盒10包括壳体12和摆动盖14.容器部分12a限定在壳体12内部,并且壳体12的末端部分形成有敞开的尖端连接部分12b。 在罐部12a和前端连接部12b之间形成有引线端口12e。 摆动罩14可旋转地安装在壳体12中,在关闭位置,摆动盖14将引导口12e和摆动盖14打开引导口12e的打开位置关闭。 摆动盖14包括能够与机械铅笔的盒容纳部46b的干涉部46e相干涉的干涉部14c。 摇摆盖14从开启位置向关闭位置沿摆动方向偏置,但是当前端连接部12b与盒接收部46b嵌合时,从关闭位置向打开位置摆动,从而使干涉部 14c被干扰部分46e干扰。

    • A cartridge (11) for storing pencil leads (14) and dispensing such leads into the lead storage chamber 30 of a pencil 31 has an assembly slidably (16) mounted therein which has a dispensing spout (21) on one end thereof. Pencil leads are contained within the cartridge and prevented from being released therefrom by a gate member (19) formed on the slidable assembly. When the slidable assembly is actuated to effect slidable motion thereof relative to the main body of the cartridge, the gate member is driven out of the path between the leads and the dispensing spout, permitting the leads to be dispensed into the chamber of the pencil.
    • 用于存储铅笔引线(14)并且将这种引线分配到铅笔31的铅存储腔室30中的盒(11)具有安装在其中的可滑动组件(16),该组件在其一端具有分配喷嘴(21)。 铅笔引线被容纳在盒内并且被形成在可滑动组件上的门构件(19)阻止从其释放。 当可滑动组件被致动以实现其相对于盒的主体的可滑动运动时,门构件被驱动离开引线和分配喷嘴之间的路径,从而允许引线被分配到铅笔的腔室中。

    • A cartridge for a mechanical pencil has a tubular body (2) wherein pencil leads are contained. Upon insertion of one end of the cartridge in a complementary passage (77) of a lead guide (7), a cylindrical axial projection (71) is received into a hole (107a) provided in a capping structure (10) of resiliently deformable material which closes the end of the cartridge. The end of the projection (71) is received and engages a membrane-like tongue part provided with a central passage 11. When relaxed, the passage 11 is of a diameter too small to allow for the transfer of leads. Engagement with the projection stresses the tongue part to expand the passage 11 and allow the lead to be transferred singly from the cartridge to the lead guide (7) for use. The capping structure (10) is received within the end of the cartridge body (2) and is provided with a circumferential flange (103) which engages the rim of the cartridge body (2).
    • 用于自动铅笔的墨盒具有容纳铅笔线的管体(2)。 当将盒的一端插入引导引导件(7)的互补通道(77)中时,圆柱形轴向突起(71)被接收到设置在弹性可变形材料的封盖结构(10)中的孔(107a)中 关闭墨盒的末端。 突起71的端部被接收并与设置有中心通道11的膜状舌部接合。当松弛时,通道11的直径太小而不能传递引线。 与突出部配合会使舌部膨胀通道11,并允许引线从药筒单独转移到引导引导件(7)以供使用。 封盖结构(10)被容纳在盒体(2)的端部内并且设置有与盒体(2)的边缘接合的周向凸缘(103)。
