摘要:
A refill for a correction pen is constructed of a molded article of a polyamide resin obtained from monomers having an aromatic ring or a naphthene ring, a molded article of a blend of two or more kinds of polyamide resins, or a molded article having a multi-layered structure of two or more layers whose innermost layer in contact with the correction fluid is constituted of a polyamide resin. The applying part of a refill unit mounted on a ballpoint type applicator having a pressurizing mechanism in linkage with clicking action is formed by press fitting the rear end of a ballpoint pen tip having a rotatable ball to the attachment portion at the front end of an ink reservoir and a metal tube is squeezed to cover the outer periphery of the attachment portion at the front end of the ink reservoir to which the tip is fitted.
