Abstract

The invention discloses a roller ball pen. The roller ball pen comprises an ink storage device, a pen point and a water device assembly, the water device assembly comprises a pen item and a water device sleeved with the pen item, the two ends of the water device are connected with the ink storage device and the pen point respectively, the water device comprises a water conveying channel, an air inlet groove and a side through groove, wherein the side through groove is communicated with the water conveying channel, the air inlet groove and the ink storage device. According to the gel ink pen, by improving the structure of the ink container, the water outlet smoothness and sealing performance of the gel ink pen can be improved, and therefore ink waste can be reduced, and the ink dryness resistance can be improved.

Description

technical field [0001] The invention relates to the technical field of writing utensils, in particular to a water-based pen. Background technique [0002] Existing straight liquid pens all adopt the sealing method of nesting a pen item outside the water container, and the cooperation state of the water container and the pen item determines the smoothness and uniformity of the ink output. If the cooperation between the water container and the pen item is too tight, it is easy to cause poor writing ink; if the gap between the water container and the pen item is too large, it is easy to cause ink leakage, resulting in ink waste. Especially when the external air pressure changes greatly, the phenomenon of ink leakage is unavoidable. [0003] When the water-based pen adopts erasable ink, due to the high cost of the erasable ink, ink leakage will cause great waste. [0004] Therefore, it is urgent to provide a water-based pen with better airtightness and stability to solve the a...
