Ink-fillable writing pen

Abstract

The invention relates to an ink-fillable writing pen. The ink-fillable writing pen utilizes the elastic force of a hollow elastomer to provide nearly constant pressure to act on ink, and can be used for writing on the medium surface with small friction force and under the condition of no gravity; if a nib is blocked, an ink filling device of the ink-fillable writing pen can be easily used for trying to repair the blockage; an ink containing space formed by the combination of an ink containing pen holder, the hollow elastomer and a sealing plug replaces an ink tube of a disposable pen refill, so that the structure is simplified, the ink containing space has larger ink containing capacity compared with the common disposable pen refill, and ink can be repeatedly added; and the nib can be replaced, so that the problem of pollution to the environment caused by frequent replacement and abandonment of disposable pen refills is avoided, and the use cost is reduced.

Description

technical field [0001] The invention relates to a pen, which may be specifically a refillable writing pen. Background technique [0002] Pens are commonly used writing tools, generally divided into pens, pencils, ballpoint pens, etc. Among them, ballpoint pens are divided into oily ballpoint pens, gel pens, and fountain pens. The different names are also called ballpoint pens, signature pens, and ballpoint pens. The principle of writing is generally to use the ball in the tip of the pen to roll on the writing medium by the ink or the weight of the ink, and the ball in the tip of the pen will take out the ink in the ink tube or apply it evenly on the writing medium. Because ballpoint pen writing requires ball rolling and ink Or the self-weight of the ink, so ordinary ballpoint pens and gel pens and ballpoint pens of the same principle cannot write normally when there is no gravity and the friction of the writing medium is small, such as on glass or smooth plastic sheets; Due...

AI Technical Summary

Problems solved by technology

[0003] The problem to be solved by the present invention is to provide a refillable writing pen, which can write on the medium surface with less friction and under the condition of no gravity; if there is a clogging of the nib, it can be easily set by using the refillable writing pen Compared with ordinary disposable refills, it has a larger ink capacity and can refill ink and replace the nib repeatedly, avoiding the problem of environmental pollution caused by frequent replacement of disposable refills and reducing the cost of use;
