Problems solved by technology

[0002] Fountain pen is main writing implement, because of its advantages such as portability, writing fluently are very popular, but this pen often takes place when stopping using for a period of time and the phenomenon that dry nib does not enter water because of the evaporation of nib moisture, causes a lot of inconvenience, after all The main reason is that there is a large gap around the nib of this pen after the cap is put on the barrel. The air in this gap will continuously plunder the small amount of water on the nib, making the nib gradually dry. At the same time, the cap and the nib The fit of the pen barrel will also cause the air flow inside and outside the cap to accelerate and take away more water due to insufficient airtightness, which will eventually cause the nib to dry out and no longer enter the water. This phenomenon needs to be eliminated.

Embodiment Construction

[0009] Choose a soft rubber mold that is more resistant to aging, such as figure 1 Shaped into a nib cover 2, it is best to use silica gel, the shape is approximately a bottomed cylinder, the elastic recovery force should be high, and a plurality of air holes 1 are processed on the cylinder wall of the upper 1 / 2 part, through adhesive or tight The matching form fixes the nib cover 2 on the inner top of the pen cap 3, such as figure 2 As shown, the diameter of the nib cover should be slightly smaller than the inner diameter of the pen cap, and the height should be about 2 / 3 of the inner height of the pen cap. When the pen cap 3 is put on the pen holder 5 during use, the nib 4 will be inserted into the hollow barrel of the nib cover 2 Inside, the lower end surface of the nib cover and part of the lower barrel wall will be received into the hollow space in the barrel under the top touch of the nib, and the nib part will naturally form a tight wrapping effect due to its own mater...
