  • a method of improving the visibility by performing a surface treatment such as a treatment with fluorine, a silicone treatment, or the like on the ink by using a rib shape or the like.
  • the method of improving the ink drainage property by the rib shape or the like has a problem in that the steps such as complicating the mold shape become complicated. Also, Even if the surface has been improved such as ink removal by the shape of the ink or surface treatment such as fluorine treatment or silicone treatment, the visibility is still insufficient, especially for dark inks such as black and blue. However, there is still a problem in the visibility of the direct liquid type writing instrument filled with the ink, which is poor in the cutting performance of the ink, and there is no such thing in practice that has excellent visibility.
  • Japanese Utility Model Publication No. 3-53902 discloses a transparent or translucent ink cylinder made of polyethylene or polypropylene, wherein the ink is a water-based ink, and the water-based ink has a terminal side.

Abstract

L'invention concerne un instrument d'écriture (A) comportant une portion réservoir d'encre (31) permettant d'y stocker de l'encre (11), caractérisé en ce que l'encre (11) contenue dans la portion réservoir d'encre (31) comprend un constituant encre (12) et un constituant couche de séparation (13) séparé, sous la forme d'une couche, du constituant encre (12), la densité et la tension de surface du constituant couche de séparation (13) étant inférieures à celles du constituant encre (12), l'encre (11) pouvant se déplacer librement à l'intérieur de la portion réservoir d'encre (31). Grâce à ces caractéristiques, on obtient un instrument d'écriture et un dispositif d'application de liquide permettant de visualiser la quantité restante d'encre.
