The gel pen has the advantages that by the adoption of the simple one-way valve principle, the purpose of circularly injecting the ink can be achieved; the gel pen is novel in construction, simple in structure and convenient to operate, resources for manufacturing gel pens and packaging the gel pens can be saved truly and effectively, the plastic rubbish generated in the using process of the gel pens is reduced effectively, the environment is well protected, and the gel pen has good popularization value.

Description

technical field [0001] The invention belongs to a gel pen, in particular to a recyclable ink filling gel pen. Background technique [0002] In today's environment where gel pen writing is more and more widespread, whether it is signing, homework, accounting, writing official documents, etc., gel pens are basically used. Although the gel pen is very good for writing, the written words are not only beautiful, but also very convenient to carry, but it also has some shortcomings of its own, that is, the service life is not long, and the ink of a gel pen is used up.

Although the gel pen is very good for writing, the written words are not only beautiful, but also very convenient to carry, but it also has some shortcomings of its own, that is, the service life is not long, and the ink of a gel pen is used up. It's over, all that's left is a plastic body that people just throw away as trash

This not only causes environmental pollution, but also aggravates the waste of resources. Especially for the earth, a planet with limited resources, human beings should use resources more rationally and save resources, so as to promote the harmonious development between man and nature. Therefore, the design of recyclable automatic injection Ink gel pens not only conform to the historical trend, but also as a responsibility of human beings, protecting the earth and saving resources is everyone's responsibility

After researching the design of most gel pens, we found that most gel pens are not suitable for refilling ink. If you pull out the nib to refill ordinary gel pens, it is inconvenient and affects the writing quality.
