摘要： A writing utensil configurable between retracted and extended configurations is provided. The writing utensil includes a body having an interior volume and an aperture. A reciprocally movable nib assembly is located in the body and includes a nib that, when in the extended configuration, traverses the aperture. To prevent the nib from drying when in the retracted configuration, a sealing element seals the aperture. In an embodiment, the sealing element is a resilient valve element that can be opened by a sleeve slidably engaging the nib assembly. After the sleeve opens the valve, the sleeve slides with respect to the nib assembly to expose the nib. In another embodiment, the sealing element can be a sliding door that is attached to the nib assembly and overlays the aperture. When the nib assembly is moved to the extended configuration, the sliding door slides in a manner that opens the aperture.
摘要翻译：提供了一种可在缩回和扩展配置之间配置的书写工具。书写用具包括具有内部容积和孔的主体。可往复移动的笔尖组件位于主体中，并且包括当处于延伸构造时穿过该孔的笔尖。为了在缩回构型中防止笔尖干燥，密封元件密封孔。在一个实施例中，密封元件是可由可滑动地接合笔尖组件的套筒打开的弹性阀元件。在套管打开阀门之后，套筒相对于笔尖组件滑动以露出笔尖。在另一个实施例中，密封元件可以是连接到笔尖组件并与孔重叠的滑动门。当笔尖组件移动到延伸构型时，滑动门以打开孔径的方式滑动。

Additional components such as a seal component, spring, compression ring, a rotational stop, and/or an O-ring may be utilized.
