Summary:A method of manufacturing an ink follower for water-base ballpoint pens, in which a thickener is constant in dispersibility for each manufacturing lot and viscosity variation is small and in which minute bubbles present in the thickener contained in the ink follower are removed, the method involves the step of uniformizing the thickener at any temperature in the range of 40 DEG C to 130 DEG C, preferably, in the range of 100 DEG C to 130 DEG C. La présente invention concerne un procédé permettant de fabriquer le bouchon suiveur d'encre des stylos à bille à encre à base aqueuse. On utilise en l'occurrence un épaississant conservant une dispersabilité constante à toutes les étapes de fabrication et présentant peu d'écarts de viscosité. Les bulles microscopiques ont été chassées de l'épaississant contenu dans le bouchon suiveur d'encre. Le procédé utilisé consiste à uniformiser l'épaississant à une température quelconque comprise dans la plage des 40 DEG C à 130 DEG C, mais de préférence dans la plage des 100 DEG C à 130 DEG C.
