    • A marking member (such as a cosmetic crayon or brush) disposed within a barrel is urged into engagement with a companion member (such as a sharpener or cosmetic mass) disposed in a cap rotatably mounted on the barrel through the action of a screw and nut device, the male member of the screw and nut device being slidably splined to the barrel, its companion female member being rotatable relative to the male member, the female member being rotated by the cap through a slippable clutch, which will slip upon engagement of the marking member against the companion member with a predetermined axial force, thereby limiting the force with which the marking member may engage its companion member and preventing crushing of the crayon or undue deformation and pressure of the brush against the cosmetic mass.
    • 设置在筒内的标记构件(例如化妆用蜡笔或刷子)被推动与配置在通过螺钉和螺母的作用旋转地安装在筒上的帽中的配对构件(例如磨刀器或化妆品块)接合 螺钉和螺母装置的阳构件可滑动地花键连接到筒体上,其伴侣阴构件可相对于阳构件旋转,阴构件通过可滑动的离合器由帽旋转,该滑动离合器将在接合 标记构件以预定的轴向力抵靠在伴侣构件上,由此限制了标记构件可以与其配合构件接合的力,并且防止了蜡笔的破碎或刷子抵靠化妆品块的不适当的变形和压力。
