Ink tank having ink injection nozzle marking pen

摘要

The present invention relates to a marking pen ink reservoir, an ink injection nozzle, and prevents local compression of the ink reservoir when the ink injection nozzle is inserted into the ink reservoir, and prevents the fibers of the ink reservoir from being drawn out when removing the ink injection nozzle, and injecting ink. The purpose is to make this uniform and smooth. In other words, in the present invention, in the ink injection nozzle of the marking pen ink reservoir, the diameter of the ink reservoir becomes narrower toward the front end so that the fibers of the ink reservoir do not get caught when the ink reservoir is retracted and local compression of the ink reservoir due to jamming when inserted into the ink reservoir. An ink supply tube portion formed of a metal tube through which ink for ink injection into an ink reservoir is supplied at the rear end of the jam prevention insert tip formed in a cone shape and the ink supply tube portion and the ink supplied to the outer surface of the ink supply tube portion are stored in ink. It is characterized in that it is composed of an ink supply hole formed to be perforated to form multiple rows in the longitudinal direction at equal intervals so as to be injected into the barrel. Accordingly, the present invention has an effect that the fibers of the ink reservoir are not caught when the ink reservoir is partially compressed and retracted due to being jammed when inserted into the ink reservoir, and ink is evenly injected into the ink reservoir.
