    • A retractable felt tip pen has a seal system that prevents air from drying out the felt between uses. The seal system can be actuated with one hand, and comprises two sealing devices that may be used in series in the pen or may be used alone. The first sealing device is a flexible self-sealing membrane, and the second is a specially-shaped and hinged cap. The membrane is actuated by extension and retraction of the felt itself. The cap may be actuated either by extension of the felt alone or by the push of a finger on the cap. Replacement of the cap is effected by snapping the cap over the end of the pen, again with one finger.
    • 可伸缩毛毡笔具有密封系统,其防止空气在使用之间弄湿毛毯。 密封系统可以用一只手来致动,并且包括两个可以在笔中串联使用或者可以单独使用的密封装置。 第一密封装置是柔性自密封膜,第二密封装置是特殊形状和铰链盖。 膜通过毡本身的伸缩而被致动。 盖可以通过单独的毛毯的延伸或通过在手指上的推动而被致动。 盖子的替换是通过用一根手指再次将盖子盖住笔的末端来实现的。

    • A combination ballpoint pen and mechanical pencil comprising a barrel with a nose cone having a hole therethrough. A plurality of different writing cartridges are provided, with each writing cartridge having a writing tip. A component is for radially positioning the writing cartridges within the barrel, so that the writing tips will face the hole in the nose cone of the barrel. Structures are for facilitating manual movement of each writing cartridge with the writing tip to and from the nose cone of the barrel. An element is for guiding one writing tip of one writing cartridge into and out of the hole in the nose cone of the barrel. When the writing tip extends out of the hole, a person can grip the barrel and write with the writing tip.
    • 一种组合圆珠笔和自动铅笔,其包括具有穿过其中的孔的具有鼻锥的筒。 提供了多个不同的写入盒,每个写入盒具有写入尖端。 组件用于将书写卡盘径向定位在镜筒内,使得写入尖端将面向镜筒的鼻锥中的孔。 结构用于促进每个写入盒的书写尖端与筒的鼻锥体的手动移动。 一个元件用于将一个写入筒的一个写入尖端引导到筒的鼻锥中的孔中。 当书写笔尖从孔中延伸出来时,一个人可以握住镜筒并用书写笔写。
