  • Patent number: 7600938
    Abstract: 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.

  • Patent number: 7140798
    Abstract: In order to inhibit titanium oxide from settling down over a long period of time and secure a leveling property of a coating fluid including an ink composition, provided is a coating fluid for a fluid applicator, comprising at least titanium oxide, a resin and an organic solvent, wherein an additive comprising an N-acylamino acid derivative whose fundamental frame is at least one selected from N-acylamino acid amides and N-acylamino acid esters is added in an amount of 0.6 to 4.5% by weight based on the total amount of the ink composition, and a content of the resin described above is 1.5 to 11 parts by weight based on a content of 1 part by weight of the additive described above.

  • Publication number: 20060075924
    Abstract: A refill for a correction pen which is excellent insolvent resistance and moldability and can make its content, i.e., a correction fluid having methyl cyclohexane as the main solvent and the remaining amount easily visible during usage and as time passes, 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.
