A gel pen for refilling ink

Abstract

The invention discloses a gel pen allowing ink to be injected repeatedly. The gel pen comprises a pen shell, a pen point and a pen cap. The pen point is connected with the pen shell. The pen cap is installed on the pen point. The gel pen is characterized by further comprising a nib, a sealed ink disc, an ink storage device, an ink extraction device and a communication rod, wherein the nib is installed in the pen point, the sealed ink disc, the ink storage device and the ink extraction device are sequentially connected and installed in the pen shell, and the nib with the ink storage device are connected through the communication rod. According to the gel pen, the advantages that a gel pen is comfortable in writing and convenient to carry and the advantages that ink can be repeatedly absorbed by a pen are combined, when the ink is used up, the ink can be extracted only by screwing off the pen point, placing a communication vessel in the ink and pulling an ink extraction control line; the gel pen can be reused multiple times and environment pollution caused by waste of refills is eradicated; the straight up and down characteristics of a traditional ink extractor are changed through the ink extraction control line, the length of the gel pen is reduced, and the ink storage space of the ink storage device is increased; the communication rod and the compressed ink storage device respectively can be made from recycled refills and plastic, waste of the refills is avoided, and wasted refills can be recycled and reused.

Description

technical field [0001] The invention relates to a gel pen, in particular to a gel pen with repeated ink filling. Background technique [0002] A ball-point pen with a writing medium whose viscosity is between water and oil is called a gel pen; a gel pen is a popular writing tool at present, and a gel pen has the advantages of both a fountain pen and a ball-point pen. Low, so it is smoother than ordinary oil-based ballpoint pens, and it is an upgraded product of oil-based ballpoint pens. [0003] The structure of a gel pen is composed of a pen holder, a refill, and a cap. In order to ensure that the ink in the refill can come out of the pen tip, the design of the refill of the gel pen relies on the piston to push the ink. Because the solid piston is not easy to control in industrial production, it can also achieve sealing. It is very difficult to achieve a very smooth effect. A slight error in size may cause the piston to be stuck or fall off (the pen does not emit water), r...

Problems solved by technology

[0003]The structure of the gel pen is composed of the pen holder, the pen core and the pen cap. In order to ensure that the ink in the pen core can come out of the pen tip, the design of the gel pen core relies on the piston Pushing the ink, because the solid piston is not easy to control in the industrial production, it is difficult to achieve the sealing and very smooth effect at the same time, a little error in the size may cause the piston to be stuck or fall off (the pen does not come out of water), the rough will be stuck, and the smooth will be As a result, the sealing effect is not good (the pressure cannot be formed to squeeze the ink). Therefore, the pen core structure design of the gel pen uses liquid silicone oil (colloidal liquid on the ink) as the piston, and replaces the new pen core after the pen core is used up. , Most of the used refills are discarded, and the discarded refills will cause environmental pollution and material waste

[0004] In the prior art, the reuse of the pen core is realized by the pen core ink injector, and the pen core ink injector refills the recovered pen core, but its There are: expensive, bulky, high power consumption, inconvenient to use, and the refill can only be refilled once and cannot be reused. It can be seen that it has not fundamentally solved the problem of reusing the refill.

[0005]Another reusable neutral refill application number 201010172303.3 (authorized announcement number CN 101830136 B), it still uses the "patch" piston type Sealed compression design, and the piston can only use liquid silicone oil, so this design is not popular, and even can't work normally

[0006]Therefore, there is no gel pen in the prior art that can realize repeated ink filling and normal writing, and the ink filling operation is simple to reduce waste
