摘要： The cap for the writing instrument comprises a jacket mounted slidably on a sealing insert or sleeve which provides a sealed moisture chamber for the writing tip when the cap is on the writing instrument. Near the writing tip there is a circular bulge on the shaft of the writing instrument which enters into a sealing engagement with an interior passage of the sealing insert. On putting the cap on the writing instrument the sealing insert is pushed over the circular bulge until it contacts a contacting stop on the jacket. Then the circular bulge presses tightly into the sealing insert and it locks the jacket to the writing instrument so that the entire arrangement is kept in that position until the cap is removed. A signal slider is attached with the sealing insert which is extendable out from the end of the jacket in order to signal in its extended position the proper seating of the cap on the writing instrument. Erroneous indications of a sealed state are prevented with our invention.

摘要翻译： 用于书写工具的盖子包括可滑动地安装在密封插入件或套筒上的护套，当封盖在书写工具上时，该封套为写入尖端提供密封的水分室。 在书写工具附近，书写工具的轴上有一个圆形凸起，它与密封插入件的内部通道形成密封接合。 将盖子放在书写工具上时，密封插件被推到圆形凸起上，直到它接触到外套上的接触止动件。 然后，圆形凸起紧紧地压入密封插入件中，并且将夹套锁定到书写工具，使得整个布置保持在该位置，直到盖被移除。 信号滑块附着有密封插入件，该密封插入件可从夹套的端部延伸出来，以便在其延伸位置发出信号，使盖子适当地安放在书写工具上。 我们的发明阻止了密封状态的错误指示。
