Large-capacity gel pen

Abstract

The invention provides a large-capacity gel pen. The gel pen capable of containinga large capacity of ink is formed in a manner that a pen ink tube also used as a pen holder is connected with a pen nib at the front end through a spiral head in a screwing manner. In use, the pen ink tube also used as the pen holdercan be filled witha large capacity of ink. As the pen holder is directly arranged into acartridge tube and connected with the pen nib into a whole in the screwing manner, the gel pen can be conveniently filled with the ink at any time.

Description

technical field [0001] The invention relates to a water-based pen, in particular to a large-capacity water-based pen. Background technique [0002] All kinds of water-based pens in use now have the structure of directly replacing the refill. Since the refill is installed in the pen barrel, the capacity of the refill is limited, resulting in a single refill that cannot be used for a long time, and the existing refill They are all one-time use products, and in the continuous replacement and use, it also causes a certain waste of resources. Contents of the invention [0003] The invention provides a large-capacity water-based pen. The pen holder is directly set as a pen core, which not only increases the ink capacity, but also can add ink at any time. [0004] The present invention includes a nib, and the adopted technical scheme is that: the water-based pen that can be loaded with large-capacity ink is a pen-ink tube that doubles as a pen holder and is screwed together with...

AI Technical Summary

Problems solved by technology

[0005] The beneficial effect of the present invention is that: by directly setting the pen holder as a pen core, and having a split structure that can be screwed with the nib, the thicker pen holder has a larger ink capacity, and the ink can be used for a long time after filling once. And the nib can be disassembled to refill ink at any time, thus solving the problem that the current water-based pen can only be used by replacing the refill and the limited capacity brings inconvenience to the use
