AI Technical Summary

Technical Problem

Conventional marker pens with acrylic nibs are expensive, prone to breakage, and require pressing to check ink flow, leading to contamination and poor writing feel, while ink discharge is hindered by atmospheric pressure and surface tension.

Method used

A mechanical paint marker pen with an ink discharge structure that uses a polyester nib, incorporates a pipe-shaped frame and guide plate, and operates based on Bernoulli's theorem to facilitate easy ink discharge by pressing the ink tank, allowing for high-viscosity ink and brush nib usage.

Benefits of technology

Enhances operational efficiency and reduces material costs by using a cost-effective polyester nib, enabling expansion into new markets like watercolor markers and nail polish, with improved ink flow and writing experience.

Abstract

To provide a mechanical-type paint marker pen that allows ink to be easily discharged by pressing the ink tank according to Bernoulli's theorem, making it easy to use and increasing operation efficiency, and that allows the use of a relatively inexpensive polyester nib instead of an expensive acrylic nib, and when a brush nib is used, the product lineup to be expanded to include watercolor markers, or the like, allows high-viscosity ink to be used, making it possible to expand into other industries such as nail polish.SOLUTION: The mechanical-type paint marker pen includes a body; an ink tank connected to the inside of the body and containing ink; an inner rod inserted into the ink tank and connected to the body; an ink discharge part fixed to the body and discharging ink; and a nib connected to the ink discharge part.SELECTED DRAWING: Figure 1
