摘要: A writing instrument comprises a writing nib having a writing tip at one end and an enlarged head portion at the other end, and a resilient seat urging the head portion of the nib toward a tip of the instrument. The nib is movably secured in a nib holder body in such a manner that a writing pressure enables the nib to move backward against the resilient force of the seat to form an ink-feed space between the head portion and the nib holder body. When the writing instrument is not in use, the head portion is engaged with the nib holder body to close the ink-feed space.
摘要翻译: 一种书写工具,包括:一端具有书写尖端和另一端具有扩大头部的书写笔尖;以及一弹性座,其朝向该器具的尖端推动笔尖的头部。 笔尖可移动地固定在笔尖保持器主体中,使得书写压力使得笔尖能够抵抗座椅的弹力向后移动,以在头部和笔尖座之间形成供墨空间。 当书写工具不使用时,头部与笔尖保持体接合以封闭供墨空间。
