Abstract

The invention discloses a pen capable of improving the sealing performance of an ink bag. The pen comprises a pen cap, a pen tip set, an ink bag and a pen holder, wherein the pen tip set is composed of a pen point sleeve, a pen tip, an ink guide assembly, a flow guide pipe, a film opener and a sealing gasket, the pen tip is arranged at the top of the pen tip sleeve in a penetrating mode, the ink guide assembly is arranged at the bottom of the pen tip in the pen tip sleeve, the flow guide pipe is arranged in the middle of the ink guide assembly, the film opener is arranged at the bottom of theflow guide pipe, the sealing gasket is arranged outside the film opener in a sleeved mode, the ink bag is arranged outside the film opener in a sleeved mode, the ink bag is composed of a connecting pipe, a sealing film, a bag pipe and a plugging head, and the pen holder is composed of a first mounting part, a handhold part, a pen cap clamping part and a spring. According to the pen, the closed film can be opened, so that ink can flow out smoothly, the plugging effect of the ink bag can be improved, the ink can be prevented from leakage, the sealing effect of the ink bag can be improved, the clamping and fixing of the pen cap at various working positions can be realized, the wear resistance of the pen holder can be improved, the service life is prolonged, the structure is simple, and the ink bag is easy to replace.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of writing instruments, in particular to the technical field of a pen capable of improving the sealing performance of an ink bag. [0003] 【Background technique】 [0004] In the existing study and life, the fountain pen is one of the essential stationery. Since the nib of the fountain pen is made of metal, it is round, elastic and smooth to write, so the fountain pen is also favored by many office workers. When writing with a pen, ink needs to be inhaled first, which brings some troubles to people carrying the pen. If people put the pen in their bag or pocket, the cap of the pen may fall off, and the ink will leak out and pollute the bag or pocket. Of course This also caused some damage to the pen. So researching a kind of fountain pen that can improve ink bag sealing performance becomes the needs of the development of the times. [0005] The fountain pens currently on the market have strong aesthe...

AI Technical Summary

Problems solved by technology

[0005] The fountain pens currently on the market have strong aesthetics, but their nibs are easily broken and broken, which is inconvenient to replace and carry. The amount of ink stored in the steel nib of traditional dip pens is small, and ink needs to be dipped frequently during the writing process. , it is very inconvenient to write in this way, and it is easy to cause discontinuity in the writing process and affect the writing effect, poor wear resistance and short service life
